<p>For my project, I have taken a data set which have 1296765 observations of 23 columns, I want to take just 10% of this data randomly. How can I do that in R.</p>
<p>I tried the below code but it only sampled out just 10 rows. But, I wanted to select randomly 10% of the data. I am a beginner so please help.</p>
<pre><code>library(dplyr)
x <- sample_n(train, 10)
</code></pre>

<p>Because Enums aren't guaranteed to be of type int...</p>
<pre><code>public enum ExampleEnum : int / ulong / whatever
</code></pre>
<p>You cannot do this with enums:</p>
<pre><code>int i = (int)exampleEnum;
</code></pre>
<p>However in my case, while I don't know the exact 'type of enum' being used, I can guarantee that it will be a "int type" of enum.</p>
<p>So I can do this:</p>
<pre><code>int i = Convert.ToInt32(exampleEnum);
</code></pre>
<p>Cool. <strong>Here's the problem</strong>: I don't know of a way to do the inverse (which I need to do), as:</p>
<pre><code>Enum exampleEnum = (Enum)exampleEnum;
</code></pre>
<p>has error:</p>
<blockquote>
<p>Cannot cast expression of type 'int' to type 'Enum'</p>
</blockquote>
<p>And I cannot find an inverse of Convert.ToInt32(Enum enum)</p>
<hr />
<p>That is the question, if you think more detail on what I'm trying to do is useful, I can provide you with it. But in a nutshell I am creating a generic GUI method that takes in any type of Enum:</p>
<pre><code>public static int EditorPrefEnumField(string label, Enum defaultValue, string editorPrefString)
</code></pre>
<p>and getting it to work (the way I want) involves converting the Enum to and from an int.</p>

<p>This function was built in to try and know how to use a dictionary properly.</p>
<pre class="lang-py prettyprint-override"><code>dict(d, 'bonjour')
hello
Unknown
Unknown
Unknown
</code></pre>
<p>It returns <code>hello</code>, and then <code>Unknown</code>. Why? It should only return <code>hello</code>. Help would be appreciated!</p>
<p>Thanks,</p>

<p>So essentially it is a simple two sum problem but there are multiple solutions. At the end I would like to return all pairs that sum up to the target within a given list and then tally the total number of pairs at the end and return that as well. Currently can only seem to return 1 pair of numbers.</p>
<p>So far my solution has to been to try and implement a function that counts the amount of additions done, and while that number is less than the total length of the list the code would continue to iterate. This did not prove effective as it would still not take into account other solutions. Any help would be greatly appreciated</p>

<p>I'm trying to make an array of unsigned char's and make a pointer which points to the first position of the array but I keep getting an error. This is my code as well as the error:</p>
<pre><code>void initBuffer
{
unsigned char buffer[size];
unsigned char *ptr;
ptr = &buffer;
}
</code></pre>
<p><a href="https://i.stack.imgur.com/OXCiP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/OXCiP.png" alt="enter image description here" /></a></p>
<p>I suspect it's a very simple type error buy I'm new to C and not sure how to fix it.</p>

<p>I am following <a href="http://scipy.github.io/devdocs/dev/contributor/conda_guide.html#conda-guide" rel="nofollow noreferrer">steps in the contributor guide</a> to create a development environment. I am up to step 2.</p>
<blockquote>
<p>The Python-level dependencies for building SciPy will be installed as part of the conda environment creation - see environment.yml</p>
<p>Note that we’re installing SciPy’s build dependencies and some other software, but not (yet) SciPy itself. Also note that you’ll need to have this virtual environment active whenever you want to work with the development version of SciPy.</p>
<p>To create the environment with all dependencies and compilers, from the root of the SciPy folder, do</p>
<p><code>conda env create -f environment.yml</code></p>
</blockquote>
<p>However this gives an error that the environment file does not exist.</p>
<p><a href="https://github.com/scipy/scipy/blob/main/environment.yml" rel="nofollow noreferrer">https://github.com/scipy/scipy/blob/main/environment.yml</a> <-- environment.yml should look like this, so I have copied and put an environment.yml file in the <code>envs</code> folder.</p>
<p>I am unsure whether I should put this file in the envs folder or if I need to go to the root of the scipy version that already exist in my pkgs folder.</p>
<pre><code>C:\\Users\\micha\\anaconda3\\envs\>conda env create -f environment.yml
EnvironmentFileNotFound: 'C:\\Users\\micha\\anaconda3\\envs\\environment.yml' file not found
</code></pre>
<p>After inserting the environment.yml file:</p>
<pre><code>C:\\Users\\micha\\anaconda3\\envs\>conda env create -f environment.yml
Collecting package metadata (repodata.json): done
Solving environment: /
</code></pre>
<p>I am still awaiting the reults, however not sure if I have done the correct thing with the directory.</p>

<p>I want to delete duplicates from a Redshift table that are true duplicates. Below is an example of two rows that are true duplicates.</p>
<p>Since it is Redshift, there are no primary keys to the table. Any help is appreciated.</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>id</th>
<th>Col 1</th>
<th>Col 2</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Val 1</td>
<td>Val 2</td>
</tr>
<tr>
<td>1</td>
<td>Val 1</td>
<td>Val 2</td>
</tr>
</tbody>
</table>
</div>
<p>I tried using window functions <code>row_number()</code>, <code>rank()</code>. Neither worked as when applying Delete command, SQL command cannot differentiate both rows.</p>
<p>Trial 1:</p>
<p>The below command deletes both rows</p>
<pre><code>DELETE From test_table
where (id) IN
(
select \*,row_number() over(partition by id) as rownumber from test*table where row*number !=1
);
</code></pre>
<p>Trial 2:</p>
<p>The below command retains both rows.</p>
<pre><code>DELETE From test_table
where (id) IN
(
select \*,rank() over(partition by id) as rownumber from test*table where row*number !=1
);
</code></pre>

<p>I am looking to implement concurrency inside part of my app in order to speed up processing. The input array can be a large array, that I need to check multiple things related to it. This would be some sample code.</p>
<p>EDITED:
So this is helpful for looking at striding through the array, which was something else I was looking at doing, but I think the helpful answers are sliding away from the original question, due to the fact that I already have a <code>DispatchQueue.concurrentPerform</code> present in the code.</p>
<p>Within a for loop multiple times, I was looking to implement other for loops, due to having to relook at the same data multiple times. The <code>inputArray</code> is an array of structs, so in the outer loop, I am looking at one value in the struct, and then in the inner loops I am looking at a different value in the struct. In the change below I made the two inner for loops function calls to make the code a bit more clear. But in general, I would be looking to make the two <code>funcA</code> and <code>funcB</code> calls, and wait until they are both done before continuing in the main loop.</p>
<pre class="lang-swift prettyprint-override"><code>//assume the startValues and stop values will be within the bounds of the
//array and wont under/overflow
private func funcA(inputArray: [Int], startValue: Int, endValue: Int) -> Bool{
for index in startValue...endValue {
let dataValue = inputArray[index]
if dataValue == 1_000_000 {
return true
}
}
return false
}
private func funcB(inputArray: [Int], startValue: Int, endValue: Int) -> Bool{
for index in startValue...endValue {
let dataValue = inputArray[index]
if dataValue == 10 {
return true
}
}
return false
}
private func testFunc(inputArray: [Int]) {
let dataIterationArray = Array(Set(inputArray))
let syncQueue = DispatchQueue(label: "syncQueue")
DispatchQueue.concurrentPerform(iterations: dataIterationArray.count) { index in
//I want to do these two function calls starting roughly one after another,
//to work them in parallel, but i want to wait until both are complete before
//moving on. funcA is going to take much longer than funcB in this case,
//just because there are more values to check.
let funcAResult = funcA(inputArray: dataIterationArray, startValue: 10, endValue: 2_000_000)
let funcBResult = funcB(inputArray: dataIterationArray, startValue: 5, endValue: 9)
//Wait for both above to finish before continuing
if funcAResult && funcBResult {
print("Yup we are good!")
} else {
print("Nope")
}
//And then wait here until all of the loops are done before processing
}
}
</code></pre>

<p>I am learning python and I what I need to achieve is to count how many denominations of 1000, 500, 200, 100, 50, 20, 10, 5, 1 , 0.25, 0.01 count base on my input data of <strong>1575.78</strong>.This specific code bums me out.</p>
<pre><code>def withdraw_money():
denoms = (1000, 500, 200, 100, 50, 20, 10,5,1,.25,0.01)
while True:
try:
withdraw = 1575.770
break
except Exception as e:
print('Incorrect input: %s' % e)
print("Here is the bill breakdown for the amount input")
for d in denoms:
count = withdraw // d
print('P%i = %i' % (d, count))
withdraw -= count * d
withdraw_money()
</code></pre>
<p>My current output is:</p>
<pre><code>Here is the bill breakdown for the amount input
P1000 = 1
P500 = 1
P200 = 0
P100 = 0
P50 = 1
P20 = 1
P10 = 0
P5 = 1
P1 = 0
P0.25 = 3
P0.01 = 2
</code></pre>
<p>which is wrong because the <code>P0.01 = 2</code> is suppose to be <code>P0.01 =3.</code></p>
<p>However this code is correct when running whole numbers like 1500, or 20 but large number with decimal it get wrong on the 0.01 denomination count.</p>

<p>I am new to Python and I need your help in getting the similarity between two sequences. Assuming they are not of the same length and some may have (-) gap symbols.</p>
<p>So here is my code bellow in getting the similarity in only one sequence.</p>
<pre><code>seq1 = "AAAATCCCTAGGGTCAT"
def similarity(seq1):
base_dic={}
for i in range(len(seq1)):
if seq1[i] in base_dic.keys():
base_dic[seq1[i]]+=1
else:
base_dic[seq1[i]]=1
for key in base_dic.keys():
base_dic[key]=base_dic[key]/len(seq1)*100
return base_dic
similarity(seq1)
Output:
{'A': 35.294117647058826,
'T': 23.52941176470588,
'C': 23.52941176470588,
'G': 17.647058823529413}
My question is how could I modify this code, so that it can take two sequences at a time and find the similarities?
for ex.
seq1 = "AAAATCCCTAGAAAGGTCAT"
seq2 = “AAGATC---TTTCTACT”
</code></pre>
<p>Any ideas? Thanks</p>
<p>i am expecting to get the similarity of A, T, G, C but not -. as they should be counted as unsimilar.</p>

<p>Sorry for the vague question.
I'm trying to add ID from Table 1</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Fruit_Name</th>
<th>Fruit_ID</th>
</tr>
</thead>
<tbody>
<tr>
<td>Apple</td>
<td>01</td>
</tr>
<tr>
<td>Banana</td>
<td>02</td>
</tr>
<tr>
<td>Pear</td>
<td>03</td>
</tr>
<tr>
<td>Grape</td>
<td>04</td>
</tr>
</tbody>
</table>
</div>
<p>to table 2 ID part.</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Fruit_Name</th>
<th>Fruit_ID</th>
<th>Grown In</th>
</tr>
</thead>
<tbody>
<tr>
<td>Apple</td>
<td></td>
<td>Farm A</td>
</tr>
<tr>
<td>Pear</td>
<td></td>
<td>Farm B</td>
</tr>
<tr>
<td>Apple</td>
<td></td>
<td>Farm B</td>
</tr>
</tbody>
</table>
</div>
<p>I want to put the same Fruit_ID from Table 1 into Table 2. So that it looks like
| Fruit_Name | Fruit_ID | Grown In |
| -------- | -------- | -------- |
| Apple | 01 | Farm A |
| Pear | 03 | Farm B |
| Apple | 01 | Farm B |
<a href="https://i.stack.imgur.com/3NGHg.png" rel="nofollow noreferrer">1</a></p>
<p>There are 35 rows in Table 1, and 300 rows in Table 2.
How do I do it?</p>
<p>I tried using
ALTER TABLE Table2 ADD FOREIGN KEY (Fruit_ID) REFERENCES Table1(Fruit_ID);</p>
<p>but it didn't work.</p>

<p>I maintain an Arduino library which uses the following code (simplified) to print results received by infrared.</p>
<pre><code>unsigned long long decodedData; // for 8 and 16 bit cores it is unsigned long decodedData;
Print MySerial;
MySerial.print(decodedData, 16);
</code></pre>
<p>Most of the 32 bit arduino cores provide the function <code>size_t Print::print(unsigned long long n, int base)</code> and compile without errors.</p>
<p>But there are 32 bit cores, which do not provide <code>size_t Print::print(unsigned long long n, int base)</code>, they only provide <code>size_t Print::print(unsigned long n, int base)</code> and there I get the expected compile time error
<code>call of overloaded 'print(decodedData, int)' is ambiguous</code>.</p>
<p>I tried to understand <a href="https://stackoverflow.com/questions/87372">Check if a class has a member function of a given signature</a> but still have no clue.</p>
<p>I want to use</p>
<pre><code> MySerial.print((uint32_t)(decodedData >> 32), 16);
MySerial.print((uint32_t)decodedData & 0xFFFFFFFF, 16);
</code></pre>
<p>in case the function <code>size_t Print::print(unsigned long long n, int base)</code> is not provided.</p>
<p>I tried</p>
<pre><code>template<typename T>
struct has_uint64_print {
template<typename U, size_t (U::*)(unsigned long long, int)> struct SFINAE {
};
template<typename U> static char test(SFINAE<U, &U::print>*);
template<typename U>
static int test(...);
static const bool has64BitPrint = sizeof(test<T>(nullptr)) == sizeof(char);
};
</code></pre>
<p>and this works (Thanks to Remy Lebeau) :-).</p>
<p>But this check does not work, since it still references the long long print function (update: and using <code>if constexpr ()</code> -which is not available for all cores- does not help).</p>
<pre><code> if(has_uint64_print<Print>::has64BitPrint){
MySerial.print(decodedData, 16);
} else {
MySerial.print((uint32_t)(decodedData >> 32), 16);
MySerial.print((uint32_t)decodedData & 0xFFFFFFFF, 16);
}
</code></pre>
<p>Is there any chance to avoid this compile error?</p>
<p>BTW. I do not want to substitute all occurences of the 64 bit print with the 2 32 bit prints, only for one seldom used and lazy implemented 32 bit core, since all mainsteam cores work well with the 64 bit print.</p>

<p>I have a dataset like this:</p>
<pre><code>row num Group
1 3 B
2 6 A
3 12 A
4 15 B
5 16 A
6 18 A
7 20 B
8 25 A
9 27 B
10 29 B
</code></pre>
<p>In R,
I would like to compare an input number with the values in <strong>num</strong>, and I would like to find the location of the closest bigger value in <strong>Group A</strong> only.</p>
<p>For example, if the input number is 8, then the closest, bigger value in group A should be 12, and I would like to get its location which should be 3. If the input is 18, then the value returned should be 18, and the location should be 6. If the input is 20, then the value returned should be 25, and the location should be 8.</p>
<p>I tried which.min, but for some reason, index 1 is always returned regardless of my imput number.</p>
<pre><code>#called the dataset f
which.min(f$num[f$Group=="A"][f$num[f$Group=="A"]>=8])
</code></pre>
<p>I would like to still use base R if possible
I would appreciate any thoughts on which part I did wrong and how to fix it.</p>
<p>Thank you.</p>

<p>i wanna ask my case about array and object, i still less of knowledge about this because still newbie. i have bunch of data as following:</p>
<pre><code> counterTraffic : [
{
id: 1,
daerah: "Bandung",
date:"1668790800000",
kendaraan: [
{rodaEmpat: 50},
{rodaDua: 22},
{truck: 30},
{Bus: 70},
]
}, {
id: 2,
daerah: "Tasik",
date:"1668877200000",
kendaraan: [
{rodaEmpat: 80},
{rodaDua: 15},
{truck: 10},
{Bus: 50},
]
},
{
id: 3,
daerah: "Bekasi",
date:"1669050000000",
kendaraan: [
{rodaEmpat: 30},

kendaraan: [
{rodaEmpat: 20},
{rodaDua: 15},
{truck: 5},
{Bus: 150},
]
}
]
</code></pre>
<p>and i want take value data of counterTraffic.kendaraan and assign to new variable.
so when i go mapping the counterTraffic, and then assign to new variable with kendaraan data</p>
<pre><code>the result have to become: let kendaraanNew = [50,22,30,70]
</code></pre>
<p>the data above from counterTraffic[0].kendaraan that already mapping before.</p>
<p>thank you for your helping</p>

<p>If I have coordinates of center point of circle, circle radius and also coordinates of the point that need to be check if a point lies inside or on the boundary of the Circle.</p>
<ul>
<li>$circle_x and $circle_y => center point latitude and longitude of the circle</li>
<li>$rad => radius(Meter) of the circle</li>
<li>$x and $y => latitude and longitude of the point that need to be check</li>
</ul>
<p>I have tried 2 ways,</p>
<pre><code> public function pointInCircle($circle_x, $circle_y, $rad, $x, $y)
{
$dx = abs($x - $circle_x);
$dy = abs($y - $circle_y);
$R = $rad;
if ($dx + $dy <= $R) {
return "inside";
} else if ($dx > $R) {
return "outside";
} else if ($dy > $R) {
return "outside";
} else if ($dx ^ 2 + $dy ^ 2 <= $R ^ 2) {
return "inside";
} else {
return "outside";
}
}
</code></pre>
<p>Second method is,</p>
<pre><code> public function pointInCircle($circle_x, $circle_y, $rad, $x, $y)
{
if ((($x - $circle_x) * ($x - $circle_x) + ($y - $circle_y) * ($y - $circle_y)) <= ($rad * $rad)){
return "inside";
} else {
return "outside";
}
}
</code></pre>
<p>But above 2 methods couldn't provide correct result, please help to find if provided point lies inside or on the boundary of the Circle using PHP.</p>

<p>I'm trying to make a navigation bar for reading information. I got the information panels to change after I click on the according tab, but the tab changes color back to its unclicked form. I want to show which tab is currently active.</p>
<p>I tried following a different person's example in here: <a href="https://stackoverflow.com/questions/68150534/color-does-not-change-corresponding-the-radio-checked-in-pure-css-tab-layout">Color does not change corresponding the radio checked in Pure CSS Tab Layout</a>

<p>During technical inspection, the car is examined to ensure it meets rule and safety requirements. Inspection is sequentially divided into scrutineering, tilt, noise, and brake tests. After each test, a sticker is placed on the car, showing that it passed. The car cannot compete without passing technical inspection.<br/>
In the scrutineering phase of the inspection, judges investigate the car for any possible rule violations. During tilt, the car is placed on a tilt stand with a driver, where it is tilted towards the fuel tank fill nozzle. It must not spill fluids up to 45 degrees and must not roll over up to 60 degrees. For the noise test, the car’s noise output from the exhaust must meet the standards set in the FSAE Rulebook. The car is also tested to ensure the kill switch is functional. To pass the brake test, a driver must accelerate the car on a short straightaway and prove brake integrity by coming to a complete stop without spinning. All four wheels must lock, and the engine must still be running.</p>
</div>
<div class="panel" id="two-panel">
<p>The business logic case is a document each team must submit to the FSAE Committee. It summarizes the business case behind the plan for production on a larger scale. The document highlights the production scale, targeted market, profitability, and key features. <br/>The presentation is given to judges at competition, where two representatives from the team, usually the Business Lead and a business team member, showcase the car and team to potential “investors”. They must also be able to answer any questions the investors may ask. The judges should be treated as if they are executives at a corporation.</p>
</div>
<div class="panel" id="three-panel">
<p>A cost report must be created and submitted before competition, which lists the cost for every part and manufacturing process required to build a complete car for production. During the event, a team representative must defend any conflicting items judges find between the car and the document submitted beforehand. Any inconsistencies that cannot be explained will be penalized in the final score. Teams are scored based on the final adjusted cost to produce their car. In addition, a real case scenario is presented to the teams requiring them to respond to a cost overrun or other production issue.</p>
</div>
<div class="panel" id="four-panel">
<p>The design event is the most heavily weighted static event. The entire team explains and defends design choices, testing, and analysis that went into building the racecar. Judges, engineers who often work in the automotive industry, question team members on their choices, and attempt to challenge every position a team takes and every fact the team states. They want to see that a team has validated every design choice, such as intake shape, suspension point locations, tire sizes/type, engine calibration, and chassis design. <br/>
A design document is submitted to support this event, which members and judges refer to when going over each system. The team is scored based on how knowledgeable the members are, the appropriateness of the parts used, and overall fit-and-finish of the car.</p>

<p>Sorry if this has been answered, but I couldn't quite seem to find an answer that addressed this particular issue. Here is a small sample of the data I'm using:</p>
<pre><code>precinct_no,newsom_count,dahle_count,difference
0001-100000-SAN PASQUAL,5,18,-13
0002-100090-SAN PASQUAL,567,622,-55
0003-100120-SAN PASQUAL,0,0,0
0004-100150-SAN PASQUAL,0,0,0
0005-105000-RANCHO BERNARDO,572,538,34
0006-105040-RANCHO BERNARDO,609,582,27
</code></pre>
<p>In the precinct_no column, how can I strip everything except for the middle six digits? I don't want the four digits in the beginning, the town names at the end, or the dashes. Just those middle six digits. I need to do this for about 3,000 rows.</p>

<p>I'm writing a function to convert a weirdly formatted Degrees Minutes Seconds to Degrees Decimal.</p>
<p>My code is:</p>
<pre><code>def fromDMS(coordinate):
lat_dms = coordinate[0:10]
lon_dms = coordinate[11:21]
lat_sign = lat_dms[0]
lat_deg = float(lat_dms[1:3])
lat_min = float(lat_dms[3:5])
lat_sec = float(lat_dms[5:])
lon_sign = lon_dms[0]
lon_deg = float(lon_dms[1:4])
lon_min = float(lat_dms[4:6])
lon_sec = float(lat_dms[6:])
lat_deg = (lat_deg + (lat_min/60) + (lat_sec/(60 * 2)))
if lat_sign == "-": lat_deg = lat_deg * -1
lon_deg = (lon_deg + (lon_min/60) + (lon_sec/(60 * 2)))
if lon_deg == "-": lon_deg = lon_deg * -1
return lat_deg, lon_deg
</code></pre>
<p>The format in question is this string</p>
<pre><code>-365535.000+1745401.000
</code></pre>
<p>where "-365535.000" (-36 degrees, 55 minutes, 35 seconds) is the latitude and "+1745401.000" (174 degrees, 55 minutes, and 1 second) is the longitude. Using an online calculator, these values should result in "-36.926389" and "174.916944", but end up as "37.20833333333333" and "174.92499999999998". I've heard that float's can be a little weird sometimes, but not to this extent.</p>

<p>I want to check if all elements of a list are not present in a string.</p>
<p>ex :</p>
<pre><code> l = ["abc","ghi"]
s1 = "xyzjkl"
s2 = "abcdef"
</code></pre>
<p>So , when l is compared with s1 it should return True,
when l is compared with s2 it should return False.</p>
<p>This is what i tried :</p>
<pre><code> all(x for x in l if x not in s1) = True
all(x for x in l if x not in s2) = True
</code></pre>
<p>I am getting True for both cases, But it should be false in second case.
Can someone please help, any solution will help, i just want to have it in a single line.</p>
<p>Thanks,</p>

<p>I want to add virtual fields / attributes to a rails model and have it included in the attributes that get returned by default when I call <code>@my_model</code></p>
<p>Assuming I have a model called Booking that has a <code>start_at</code> and <code>end_at</code> that are both datetime fields.</p>
<pre class="lang-ruby prettyprint-override"><code>@booking = Booking.new(start_at: DateTime.now, end_at: DateTime.now + 4.hours)
</code></pre>
<p>When I print the booking or say render it as json etc I get the following:</p>
<pre class="lang-ruby prettyprint-override"><code>p @booking
# Booking
id => 1,
start_at => Wed, 30 Nov 2022 10:50:20 +0800,
end_at => Wed, 30 Nov 2022 14:50:22 +0800
</code></pre>
<p>All standard so far.</p>
<p>Now I want to add virtual attributes called <code>start_date, start_time, end_date, end_time</code> that will be derived from the <code>start_at</code> and <code>end_at</code> fields</p>
<p>So I add them as attributes to the class:</p>
<pre class="lang-ruby prettyprint-override"><code>class Booking < ApplicationRecord
attr_accessor :start_date, :start_time, :end_date, :end_time
def start_time
self.start_at.strftime('%H:%M')
end
...etc
end
</code></pre>
<p>so now I print the model again:</p>
<pre class="lang-ruby prettyprint-override"><code>
@booking
# Booking
id => 1,
start_at => Wed, 30 Nov 2022 10:50:20 +0800,
end_at => Wed, 30 Nov 2022 14:50:22 +0800
</code></pre>
<p>The virtual attributes are not shown.</p>
<p>However if I add them to the attributes method I can call <code>@booking.attributes</code>:</p>
<pre class="lang-ruby prettyprint-override"><code>
class Booking < ApplicationRecord
attr_accessor :start_date, :start_time, :end_date, :end_time
def start_time
self.start_at.strftime('%H:%M')
end
def attributes
super.merge({'start_time' => start_ime})
end
end
@booking.attributes
# Booking
id => 1,
start_at => Wed, 30 Nov 2022 10:50:20 +0800,
end_at => Wed, 30 Nov 2022 14:50:22 +0800
start_time => '10:50'
...etc
</code></pre>
<p>So my question is how can i modify what attributes get returned by default, so I don't have to call .attributes on the model every time? I would like to just do <code>render json: @booking</code> and have all attributes (including the virtual ones) included.</p>
<p>Thanks in advance</p>

<p>I'm creating a website using NextJS and Docker so that I can easily deploy it. I used <code>npx-create-next-app</code> to initialize it and used <a href="https://github.com/vercel/next.js/blob/canary/examples/with-docker/Dockerfile" rel="nofollow noreferrer">this Dockerfile</a> (slightly modified) to containerize it. Since I wanted to use SSL with my server without going through the hassle of setting up a proxy, I followed <a href="https://noobgrammer.com/2021/03/07/enable-https-in-local-nextjs-application/" rel="nofollow noreferrer">this article</a>, and setup the custom server.</p>
<p>This worked fine when I ran it outside of a docker container, and performed as expected, serving over HTTPS. However when I containerized it, and tried to open the webpage over HTTPS, I came up with <code>SSL_ERROR_RX_RECORD_TOO_LONG</code>, but I could open the page using just HTTP (which I could not do when running outside of a container). Some googling led me to <a href="https://stackoverflow.com/questions/20576362/running-https-not-on-443-how-is-this-possible">this question</a>, from which I concluded that when running outside of a docker container, the custom server runs the server over HTTPS, as expected, however when I containerize it, it starts running HTTP, even though no code has been changed.</p>
<p>I'd expect the behavior to be the same when running locally or containerized.</p>
<p>At first I assumed this was due to invalid <code>key</code> and <code>cert</code> values in <code>httpsOptions</code> however I wasn't able to find anything that would make them invalid, and I don't see how that would cause this strange behavior. I tried changing the Docker run environment from <code>node:alpine-16</code> to just <code>node:latest</code> to see if it had something to do with the parent image, but that was fruitless.</p>
<p>One other minor issue I had is that <code>console.log</code> does not seem to output to the container's log for some reason, I tried googling this but didn't find much of anything pertaining to it. This has made debugging much harder as I can't really output any debug data. The only log I get when running inside of a container is <code>Listening on port 3000 url: http://localhost:3000</code>, which I assume is output by some library/package as it isn't anywhere in my code.</p>
<p>Here is my custom server code in case it would be helpful:</p>
<pre class="lang-js prettyprint-override"><code>const https = require('https');
const fs = require('fs');
const { parse } = require('url');
const next = require('next');
const dev = process.env.NODE_ENV !== 'production';
const hostname = "127.0.0.1";
const port = process.env.PORT || 3000
const app = next({ dev, hostname, port })
const handle = app.getRequestHandler()
const httpsOptions = {
key: fs.readFileSync('./cert/privkey.pem'),
cert: fs.readFileSync('./cert/fullchain.pem')
};
app.prepare().then(() => {
https.createServer(httpsOptions, async (req, res) => { // When running on docker this creates an HTTP server instead of HTTPS
const parsedUrl = parse(req.url, true)
const { pathname, query } = parsedUrl
await handle(req, res, parsedUrl)
}).listen(port, (err) => {
if(err) throw err
console.log(`Ready on https://localhost:${port}`)
})
})
</code></pre>
<p>Link to a reproducible example <a href="https://github.com/jaydevelopsstuff/Docker-HTTPS-Bug-MRE" rel="nofollow noreferrer">here</a>.</p>

<p>I'm trying to create a shiny app with multiple actionButtons that render unique text to the same varbatimTextOutput. I'd like it to work like this, where buttons 1 and 2 would print different text to the same place:</p>
<p><a href="https://i.stack.imgur.com/hbygY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hbygY.png" alt="enter image description here" /></a></p>
<p>Here's what I tried:</p>
<pre><code>library(shiny)
ui <- fluidPage(
actionButton("button1", "Button 1"),
actionButton("button2", "Button 2"),
verbatimTextOutput("button_out", placeholder = TRUE)
)
server <- function(input, output) {
button_out <- eventReactive({
input$button1
}
,{
paste0("You pressed button 1!")
})
button_out <- eventReactive({
input$button2
}
,{
paste0("You pressed button 2!")
})
output$button_out <- renderText({
button_out()
})
}
shinyApp(ui = ui, server = server)
</code></pre>
<p>I was expecting this to allow both actionButtons to output to the same place, but instead only Button 2 works, I guess because the code for that is overwriting the code for button 1. I considered putting an if statement in eventReactive, but I'm not exactly sure how to do it?</p>
<p>Is there a way to do this that I'm not seeing?</p>

<p>So I have a problem while doing the search filtering features for searching through all columns in the Datagrid table; I've implemented the search based on the selected column field, which is working just fine, and there is an option for the search input to search through the <code>All columns</code>.</p>
<p>I get all the column data dynamically from the MUI Grid API and the <code>valueTwo</code> array is the representation of the column data that I got from the MUI Grid API.</p>
<pre><code>const valueOne = [
{
name: 'Jacqueline',
reference: 'PRD-143',
active: true,
},
{
name: 'Jacqueline',
reference: 'PRD-143',
active: true,
},
{
name: 'Jacqueline',
reference: 'PRD-143',
active: true,
}
]
</code></pre>
<pre><code>const valueTwo = [
{
id: '01',
field: 'name',
headerName: 'Name'
},
{
id: '02',
field: 'reference',
headerName: 'Reference'
},
{
id: '01',
field: 'active',
headerName: 'Status'
},
]
</code></pre>
<p><a href="https://i.stack.imgur.com/I1ve2.png" rel="nofollow noreferrer">This is the application, image</a></p>
<p>This the hooks that I write</p>
<pre><code>export function useSearchTable<T>(

}, [
debouncedSearchState,
tableData,
filteredColumnHeaders,
selectedColumnHeader,
]);
return {
setFilteredColumnHeaders,
setSelectedColumnHeader,
selectedColumnHeader,
};
}
</code></pre>
<p><code>columnTempData</code> is basically an array of string containing the field name from the column header data that I set in <code>filteredColumnHeaders</code>. And things that needs to be fix is on the <code>// TODO</code> comment</p>
<p>The code that I expect is to get all the filtered data based on the search through all the columns with the column data that comes from the MUI Grid API.</p>
<p>I'm a one-man engineer and I really need your assistance here :)</p>
<p>I've tried to loop through the column field data and then looping the table list data and access each key based on the column field data, something like this:</p>
<pre><code> columnTempData.forEach((columnName) => {
allColumnFilter = dataItems.filter((itemData: any) => {
if (
typeof itemData[columnName] === `boolean` ||
typeof itemData[columnName] === `number`
) {
String(itemData[columnName])
.toLowerCase()
.includes(debouncedSearchState.toLowerCase());
}
if (typeof itemData[columnName] === `object`) {
itemData[columnName]?.name
.toLowerCase()
.includes(debouncedSearchState.toLowerCase());
}
return itemData;
});
});
</code></pre>
<p>It should have been returning the all filtered data based on the input given. so no matter what column is being search the data is going to filtered based on the input.</p>

<p>Operations on bits.
How to take 2 bits from byte like this:
take first 2 from 12345678 = 12;
Make new byte = 00000012</p>
<p>For example as asked in discussion by jspit :</p>
<pre><code>$char = 'z'; //is 122, 0111 1010
$b = $char & '?'; // ? is 63, 0011 1111
echo $b; //$b becomes 58 and shows ':'
//if integer used you get:
$b = $char & 63;// 63 is 0011 1111 as '?' but $char is string and you get 0 result:
echo $b; //$b becomes 0 because conversion to integer is used from string and $char becomes 0 and get 0 & 63 = 0, and here is error.
</code></pre>
<p>For clearance operation is on bits not on bytes, but bits from bytes.
'string' >> 1 not work, but this is second problem.</p>
<p><a href="https://php10.5v.pl/safetoken/" rel="nofollow noreferrer">Codes of char You can check on my site generating safe readable tokens</a>, with byte template option on. Site is in all available languages.</p>
<p>I think I found good answer here:
<a href="https://stackoverflow.com/questions/48516510/how-to-bitwise-shift-a-string-in-php">how to bitwise shift a string in php?</a></p>
<p><em>PS. Sorry I cant vote yours fine answers but I have no points reputation here to do this ;)...</em></p>

<p>I am trying to make a program of a chess board, When a user inputs an x and y value it will either output "black" or "white".</p>
<pre><code>x = int(input("Please enter your (x) first number 1-8::"))
y = int(input("Please enter your (y) second number 1-8::"))
column = x % 2
row = y % 2
if column %2 == 0 and row %2 == 1:
print("")
print("white")
elif row %2 ==0 and column %2 == 1:
print("")
print("black")
</code></pre>
<p>Whenever i input 1 for "x" and 2 for "y" it outputs "black", great this is the correct output. But whenever i input some other numbers such as 2 and 2, it gives me a blank output. Whenever i input 1 and 4, it outputs "black" which the correct output should have been "white. How do i make it so that whenever user inputs two numbers ranging from 1 to 8, it outputs the correct colour tile? I am not trying to make the code more advanced but would appreciate some help!</p>
<p>This is the chess board i am basing the colours on.( Do not mind the text on the picture)</p>

<p>As the title explains, how could I create a function <code>func</code> (using numpy or math modules) to find the nearest member of the geometric sequence (2, 4, 8, 16, 32, 64, 128 . . . )?</p>
<p>For example, <code>func(3)</code> should yield 2, <code>func(20)</code> should yield 16, and <code>func(128)</code> should yield 128.</p>
<p>I cannot find any information on this problem. Most rounding problems discuss rounding to the nearest multiple of some number, rather than to the nearest member of a geometric sequence.</p>

<p>I have a code to solve a Sudoku recursively and print out the one solution it founds.
But i would like to find the number of multiple solutions.
How would you modify the code that it finds all possible solutions and gives out the number of solutions?
Thank you! :)</p>
<p>code:</p>
<pre><code>
board = [
[7,8,0,4,0,0,1,2,0],
[6,0,0,0,7,5,0,0,9],
[0,0,0,6,0,1,0,7,8],
[0,0,7,0,4,0,2,6,0],
[0,0,1,0,5,0,9,3,0],
[9,0,4,0,6,0,0,0,5],
[0,7,0,3,0,0,0,1,2],
[1,2,0,0,0,7,4,0,0],
[0,4,9,2,0,6,0,0,7]
]
def solve(bo):
find = find_empty(bo)
if not find:
return True
else:
row, col = find
for num in range(1,10):
if valid(bo, num, (row, col)):
bo[row][col] = num
if solve(bo):
return True
bo[row][col] = 0
return False
def valid(bo, num, pos):
# Check row
for field in range(len(bo[0])):
if bo[pos[0]][field] == num and pos[1] != field:
return False
# Check column
for line in range(len(bo)):
if bo[line][pos[1]] == num and pos[0] != line:
return False
# Check box
box_x = pos[1] // 3
box_y = pos[0] // 3
for i in range(box_y*3, box_y*3 + 3):
for j in range(box_x * 3, box_x*3 + 3):
if bo[i][j] == num and (i,j) != pos:
return False
return True
def print_board(bo):
for i in range(len(bo)):
if i % 3 == 0 and i != 0:
print("- - - - - - - - - - - - - ")
for j in range(len(bo[0])):
if j % 3 == 0 and j != 0:
print(" | ", end="")
if j == 8:
print(bo[i][j])
else:
print(str(bo[i][j]) + " ", end="")
def find_empty(bo):
for i in range(len(bo)):
for j in range(len(bo[0])):
if bo[i][j] == 0:
return (i, j) # row, col
return None
if __name__ == "__main__":
print_board(board)
solve(board)
print("___________________")
print("")
print_board(board)
</code></pre>
<p>I already tried to change the return True term at the Solve(Bo) Function to return None/ deleted it(For both return Terms) that it continues…
Then the Algorithm continues and finds multiple solutions, but in the end fills out the correct numbers from the very last found solutions again into 0’s. This is the solution then printed out.</p>

<p>So I have a program that takes in the currently logged in user and updates their profile image.
Initially I had a function based view, and a url matching pattern (the url for accessing profile, and thereby editing it is localhost:8000/profile)</p>
<pre><code>#views.py
@login_required
def profile(request):
if request.method=="POST":
u_form=UserUpdateForm(request.POST, instance=request.user)
p_form=ProfileUpdateForm(request.POST, request.FILES, instance=request.user.profile)
if u_form.is_valid() and p_form.is_valid():
u_form.save()
p_form.save()
messages.success(request, "Your account has been updated!")
return redirect('profile')
else:
u_form=UserUpdateForm(instance=request.user)
p_form=ProfileUpdateForm(instance=request.user.profile)
context={'u_form':u_form, 'p_form':p_form}
return render(request, 'users/profile.html', context)
#following line in URLpatterns of urls.py
path('profile/', user_views.ProfileUpdateView.as_view(), name='profile'),
</code></pre>
<p>It worked fine. However when I tried changing it to a class based view as below, it started giving errors</p>
<pre><code>#views.py
class ProfileUpdateView(UpdateView):
model=Profile
fields=['image']
</code></pre>
<p>Case 1: I had this in urls.py URLpatterns</p>
<pre><code> path('profile/', user_views.ProfileUpdateView.as_view(), name='profile'),
</code></pre>
<p>It gave an error -</p>
<p>(<a href="https://i.stack.imgur.com/6mXfI.png" rel="nofollow noreferrer">https://i.stack.imgur.com/6mXfI.png</a>)](<a href="https://i.stack.imgur.com/6mXfI.png" rel="nofollow noreferrer">https://i.stack.imgur.com/6mXfI.png</a>)
I don't understand why this error popped up because there is no page specific ID, like profile/1, profile/2 - just profile/ because the user is automatically identified by who is currently logged in hence no need to pass in a separate parameter in the url</p>
<p>Case 2: after I added in pk parameter</p>
<pre><code>path('profile/<int:pk>/', user_views.ProfileUpdateView.as_view(), name='profile'),
</code></pre>
<p>This error pops up
(<a href="https://i.stack.imgur.com/Op9eQ.png" rel="nofollow noreferrer">https://i.stack.imgur.com/Op9eQ.png</a>)](<a href="https://i.stack.imgur.com/Op9eQ.png" rel="nofollow noreferrer">https://i.stack.imgur.com/Op9eQ.png</a>)</p>
<p>I have been stuck for a day now. I went through the Django documentation and MDN docs as well. Still can't figure out</p>

<p>How to let the query result be ordered by the exact order of passed items in the <code>WHERE</code> clause?</p>
<p>For example, using this query:</p>
<pre class="lang-sql prettyprint-override"><code>SELECT id, name FROM my_table
WHERE id in (1,3,5,2,4,6)
ORDER BY id
</code></pre>
<p>Result:</p>
<pre><code>id | name
---------
1 | a
2 | b
3 | c
4 | d
5 | e
6 | f
</code></pre>
<p>What I expected:</p>
<pre><code>id | name
---------
1 | a
3 | c
5 | e
2 | b
4 | d
6 | f
</code></pre>
<p>I noticed that there is a <code>FIELD()</code> function in MySQL. Is there an equivalent function in PostgreSQL?</p>

<p>Write a function called find that will take a list of numbers, my_list, along with one other number, key. Have it search the list for the value contained in key. Each time your function finds the key value, print the array position of the key. You will need to juggle three variables, one for the list, one for the key, and one for the position of where you are in the list.</p>
<p>Copy/paste this code to test it:</p>
<pre><code>my_list = [36, 31, 79, 96, 36, 91, 77, 33, 19, 3, 34, 12, 70, 12, 54, 98, 86, 11, 17, 17]
find(my_list, 12)
find(my_list, 91)
find(my_list, 80)
</code></pre>
<p>check for this output:</p>
<pre class="lang-none prettyprint-override"><code>Found 12 at position 11
Found 12 at position 13
Found 91 at position 5
</code></pre>
<p>Use a for loop with an index variable and a range. Inside the loop use an if statement. The function can be written in about four lines of code.</p>
<p>I tried this:</p>
<pre><code>def find(my_list, key):
index = 0
for element in my_list:
if key == element:
print(index)
index += 1
my_list = [36, 31, 79, 96, 36, 91, 77, 33, 19, 3, 34, 12, 70, 12, 54, 98, 86, 11, 17, 17]
find(my_list, 5)
</code></pre>
<p>But nothing really happened, no error, no result.</p>
<p>I've been struggling with this problem for while now, some help is really appreciated!</p>

<p>In my CPP system whenever I generate a random number using rand() I always get a value between 0-32k while in some online videos and codes it is generating a value between 0-INT_MAX. I know it is dependent on RAND_MAX. So it there some way to change this value such that generated random number are of the range 0-INT_MAX
Thanks in advance for the help :)</p>
<pre><code>#include<bits/stdc++.h>
using namespace std;
int main(){
srand(time(NULL));
for(int i=1;i<=10;i++){
cout << rand() << endl;
}
}
</code></pre>
<p>I used this code and the random number generated are
5594
27457
5076
5621
31096
14572
1415
25601
3110
22442</p>
<p>While the same code on online compiler gives
928364519
654230200
161024542
1580424748
35757021
1053491036

<p>In other words, does PowerShell's <code>Expand-Archive</code> have an equivalent to <code>unzip</code>'s <code>-j</code> command-line argument? If not, are there alternatives <em>on Windows</em>?</p>
<p>I have tried <code>Expand-Archive -Path thing.zip -DestinationPath "somepath" -Force</code>, which just puts the directory structure in another folder called <code>somepath</code>.</p>

<p>I am trying to rearrange the rows in a csv based on the key given in 5th column of my data.
My data looks like this (<strong>test.csv</strong>):</p>
<pre><code>Col A,Col B,Col C,Col D,Col E
A,Data 1,Category 1,Name 1,C
B,Data 2,Category 2,Name 2,C
C,Data 3,Category 3,Name 3,C
D,Data 4,Category 4,Name 4,C
E,Data 5,Category 5,Name 5,C
F,Data 6,Category 6,Name 6,C
</code></pre>
<p>I am trying to rearrange it so that the row containing the key value in first column is at top (in this case the key value is <strong>C</strong>)</p>
<p>Desired output :</p>
<pre><code>Col A,Col B,Col C,Col D,Col E
C,Data 3,Category 3,Name 3,C
A,Data 1,Category 1,Name 1,C
B,Data 2,Category 2,Name 2,C
D,Data 4,Category 4,Name 4,C
E,Data 5,Category 5,Name 5,C
F,Data 6,Category 6,Name 6,C
</code></pre>
<p>I have written the below code and also getting the desired result doing so i am generating two temporary files , just wondering if there is a better solution :</p>
<pre><code>sed 1d test.csv > input.csv
key=`awk -F"," -v 'OFS=,' '{ print $5}' input.csv | uniq`
awk -F"," -v 'OFS=,' '{if($1 == "'$key'") print}' input.csv > temp.csv
cat temp.csv input.csv > temp2.csv
awk '!seen[$0]++' temp2.csv > output.csv
sed -i '1iCol A,Col B,Col C,Col D,Col E' output.csv
</code></pre>
<p>Please help !</p>

<p>Here the code that I create to replace some value at txt file.
I want to replace the value 0 with 3 for lines which do not start with "#".</p>
<pre><code>using (StreamWriter sr = new StreamWriter(@"D:\Testing\Ticket_post_test.txt"))
foreach(string line in File.ReadLines(@"D:\Testing\Ticket_post.txt"))
{
string[] getFromLine = line.Split(' ');
if (getFromLine[0].Equals("#") == false)
{
if (getFromLine[10].Equals("0") == true) ;
(getFromLine[10]).Replace("0", "3");
}
sr.WriteLine(line);
}
</code></pre>

<p>I want to make sure my executable has debug info, trying the linux equivalent doesn't help:</p>
<pre class="lang-bash prettyprint-override"><code>$ file ./my_lovely_program
./my_lovely_program: Mach-O 64-bit executable arm64 # with debug info? without?
</code></pre>
<p><strong>EDIT</strong> (from the answer of <a href="https://stackoverflow.com/users/15949328/haggbart">@haggbart</a>)</p>
<p>It seems that my executable has <em>no</em> debug info (?)</p>
<pre><code>$ dwarfdump --debug-info ./compi
./compi: file format Mach-O arm64
.debug_info contents: # <--- empty, right?
</code></pre>
<p>And with the other option, I'm not sure:</p>
<pre class="lang-bash prettyprint-override"><code>$ otool -hv ./compi
./compi:
Mach header
magic cputype cpusubtype caps filetype ncmds sizeofcmds flags
MH_MAGIC_64 ARM64 ALL 0x00 EXECUTE 19 1816 NOUNDEFS DYLDLINK TWOLEVEL WEAK_DEFINES BINDS_TO_WEAK PIE
</code></pre>
<p>This is <em>very weird</em> because I can <em>perfectly</em> debug it with lldb</p>
<pre><code>(lldb) b main

<p>I have the following code on which I perform a custom type of null checking of my parameters. I do it that way to avoid writing 3 separate if statements (adds cyclomatic complexity) and in my opinion it just looks cleaner. However, VS2022, on NET6 refuses to take away the null warning on the previously validated parameters.</p>
<p>Here's an example: I perform the custom null validation on all params and just do one manually (logger). Only the one done manually gets to be clean with no warnings. Any ideas how to make it work with custom null validations?</p>

<p>For this reason, what I do is get to the level of each type of movement, be it transfer, inventory inputs or outputs, and I do it as follows:</p>
<pre><code>return this.connect().then((db) => {
return (
db
.collection(collection)
// The following aggregation uses the $unwind stage to output a
// document for each element in the movements.outputs array
.aggregate([
// Stage 1
{ $unwind: '$movements' },
// Stage 2
{ $unwind: '$movements.transfers' },
// Group by code field
{
$group: {
code: ...,
},
},
])
// The following project only returns the movements.transfers object
.project({
transfer: '$movements.transfers',
})
.sort({ 'transfer.code': -1 })
.toArray()
);
});
</code></pre>
<p>I have tried to use <code>merge</code> or <code>group</code> but have not been able to do what I expect based on the <code>code</code> parameter. Any other way to achieve this?</p>

<p>I'm running into some problems with my axios get request. I'm trying to fetch stock information using the TwelveData API. Here is my code:</p>
<pre><code>const axios = require('axios');
require('dotenv').config()
const getTickerList = async() => {
await axios.get(`https://api.twelvedata.com/stocks?apikey=${process.env.API_KEY}&symbol=AAPL&country=US`).then(response => console.log(response.data));
}
</code></pre>
<p>When I execute that code, I get a really strange data response that I have attached: <a href="https://i.stack.imgur.com/23PTv.png" rel="nofollow noreferrer">link to pic</a></p>
<p>I would appreciate any help or advice - thanks!</p>

<p>Is it possible to run PostgreSQL 11's <code>VACUUM FULL</code> for a short while and then get some benefit? Or does cancelling it midway cause all of its progress to be lost?</p>
<p>I've read about <code>pg_repack</code> (<a href="https://aws.amazon.com/blogs/database/remove-bloat-from-amazon-aurora-and-rds-for-postgresql-with-pg_repack/" rel="nofollow noreferrer">https://aws.amazon.com/blogs/database/remove-bloat-from-amazon-aurora-and-rds-for-postgresql-with-pg_repack/</a>) but the way it works (creating new tables, copying data, etc.) sounds risky to me. Is that my paranoia or is it safe to use on a production database?</p>
<p>Backstory: I am working with a very large production database on AWS Aurora PostgreSQL 11. Many of the tables <em>had</em> tens of millions of records but have been pruned down significantly. The problem is that the table sizes on disk (and in the snapshots) have not decreased because <code>DELETE</code> and <code>VACUUM</code> (without <code>FULL</code>) do not shrink the files. These tables are in the hundreds of gigabytes range and I'm afraid running <code>VACUUM FULL</code> will take <em>forever</em>.</p>

<p>I want to put items(item1, item2, item3) in "li".
When I used flex, the prefix disappeared!</p>
<p>(here, I use tailwind v2.2.19)</p>
<pre><code><ol class="list-decimal">
<li class="flex">
<div>item1</div>
<div>item2</div>
<div>item3</div>
</li>
<li>item</li>
<li>item</li>
</ol>
</code></pre>
<p>then I got ...</p>
<p><a href="https://i.stack.imgur.com/Pc3ou.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Pc3ou.png" alt="enter image description here" /></a></p>
<p>I really need the prefix, use grid is not fit for my situation.</p>
<p>please help, thanks!!!</p>

<p>I am trying to compute number of days between a range of dates input by the user using date picker using the following script:</p>
<pre><code> $(document).ready(function () {
$('#datepicker1').datepicker();
$('#datepicker2').datepicker();
$('#datepicker3').datepicker();
$('#datepicker4').datepicker();
$(function() {
let $fromDate = $('#fromdate'),
$toDate = $('#todate'),
$numberDays = $('#leavedays'),
$sfromDate=$('#sfromdate'),
$stoDate=$('#stodate'),
$snumberDays=$('#sleavedays');
$fromDate.datepicker().on('change', function(){
$toDate.datepicker('option', 'minDate', $(this).val());
$numberDays.val(calculateDateDiff($toDate.val(), $(this).val())+1);
});
$toDate.datepicker().on('change', function(){
$fromDate.datepicker('option', 'maxDate', $(this).val());
$numberDays.val(calculateDateDiff($(this).val(), $fromDate.val())+1);
});
$sfromDate.datepicker().on('change', function(){
$stoDate.datepicker('option', 'minDate', $(this).val());
$snumberDays.val(calculateDateDiff($stoDate.val(), $(this).val())+1);
});
$stoDate.datepicker().on('change', function(){
$sfromDate.datepicker('option', 'maxDate', $(this).val());
$snumberDays.val(calculateDateDiff($(this).val(), $sfromDate.val())+1);
});
function calculateDateDiff(endDate, startDate) {
if (endDate && startDate) {
let e = moment(endDate),
s = moment(startDate);
return e.diff(s, "days");
}
return null;
}
});
});
</code></pre>
<p>The script is able to return the correct difference between from date and to date, but I want to exclude weekend while computing the difference. Please help how to proceed for the same</p>

<p>I know the question can be a little weird to understand, so I'll try to explain the best I can the problem</p>
<p>I was trying to align some items but I don't know why one of them is below the other by a few pixels. [This is how it looks][1]</p>
<p>As far as I know, in my code, nothing is making that second item to be some pixels below the others</p>

<p>I want to print "ping" "pong", which are in same class but different method, 5 times using synchronized block.</p>
<p>The problem is that it stops after print ping pong once.</p>
<p>How can I print ping pong 5 times?</p>
<p>I think I put notifyAll() and wait() in right place.</p>
<p>print result</p>
<pre><code>ping
pong
</code></pre>
<p>here is my main class</p>
<pre><code>public class ThreadTest2 {
public static void main(String[] args) throws {
Thread thread1 = new Thread(() -> {
forLoop("a");
});
Thread thread2 = new Thread(() -> {
forLoop(null);
});
thread1.setPriority(10);
thread2.setPriority(1);
thread1.start();
thread2.start();
}
static void forLoop(String target) {
AA aa = new AA();
try {
for(int i=0; i<5; i++){
if(target != null){
aa.ping();
}
else{
aa.pong();
}
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
</code></pre>
<p>here is my ping pong class</p>
<pre><code>public class AA {
Thread thread;
public void ping() throws InterruptedException {
synchronized (this) {
System.out.println("ping");
wait();
notifyAll();
}
}
public void pong() throws InterruptedException {
synchronized (this) {
System.out.println("pong");
notifyAll();
wait();
}
}
}
</code></pre>
<p>Thank you!</p>
<pre><code>ping
pong
ping
pong
ping

<p>I am trying to store a 2D vector into a .DAT file and I would like to add a space at the start of every row. An example of a desired output looks like this:</p>
<pre><code> 0.0000000E+00 0.0000000E+00
2.0020020E-03 0.0000000E+00
4.0040040E-03 0.0000000E+00
6.0060060E-03 0.0000000E+00
8.0080080E-03 0.0000000E+00
1.0010010E-02 0.0000000E+00
1.2012012E-02 0.0000000E+00
</code></pre>
<p>You can see at the front of 0, 2e-3, 4e-3, etc. there is a space. My code is trying to do that way</p>
<pre><code>data = np.column_stack((x, y))
with open('output.dat', 'w') as datfile:
for _ in range(N):
np.savetxt(datfile, data, delimiter = " ")
</code></pre>
<p>The current output looks like this:</p>
<pre><code>0.000000000000000000e+00 0.000000000000000000e+00
1.250156269533691795e-04 0.000000000000000000e+00
2.500312539067383591e-04 0.000000000000000000e+00
3.750468808601075386e-04 0.000000000000000000e+00
5.000625078134767181e-04 0.000000000000000000e+00
6.250781347668459519e-04 0.000000000000000000e+00
7.500937617202150772e-04 0.000000000000000000e+00
</code></pre>
<p>As you can see, there is no space at the front of every line. Do you have any solutions for this? Thanks!</p>

<p>I am building a small web page as an exercise.
I'm trying to arrange three photos next to three texts aside each other and it's not working.
My idea is that they look like this:</p>
<pre><code> Photo---> text
text--->photo
photo--->text
</code></pre>
<p>And for that I wrapped the package of images and text in a
then in css I put this:</p>
<pre><code> .grid-wrapper {
display:grid;
grid-template-columns. auto auto auto;
grid-gap: 10px;
}
</code></pre>
<p>And well it hasn't worked.
I appreciate your advice</p>

<p>I have the following TextView defined:</p>
<pre><code><TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:autoLink="web"
android:linksClickable="true"
android:id="@+id/googleplayservices"
android:layout_marginLeft="40dp"

android:fontFamily="@font/inter_medium"
android:paddingTop="@dimen/_5sdp"
android:text="@string/Google_Play_Services"
android:textColor="@color/black"
android:textSize="@dimen/_12sdp" />
</code></pre>
<p>where <code>@string/Google_Play_Services</code> is a string resource that contains <code><a href="some site">Link text</a></code>.</p>
<p>Android is highlighting the links in the TextView, but they do not respond to clicks. What am I doing wrong? Do I have to set an onClickListener for the TextView in my activity for something as simple as this?</p>

<p>This is my data and I have calculateDistance() function. And location is the location of where mause is clicked on map.What I want is to pass each element in data to pass my calculateDistance() function and save the result in distance array and pass it to useState hook. How can i do that?
I get output as NaN array with that code.</p>

</code></pre>
<p>And here is the calculate distance function</p>
<pre><code>const [distance, setDistance] = useState(null);
const data = useHeroesData();
//console.log(data);
const calculateDistance = (lat1, lon1, lat2, lon2) => {

<p>I tried to implement a scrollTo() method function to the position of the pressed button, but that is more of a hack than a real solution since it will keep re-rendering and scrolling. Also, the modal that I am trying to activate has other stateful components within it, causing more re-renders. Another attempted fix was trying to memo-ize the modal, however the official docs suggest that premature-optimization isn't not a real solution and will lead to more bugs down the . Thank you.</p>

<p>I am building a Python library and I have the requirement inside one of the modules to get the current version of this same library and make decisions based on the current version.
Is this possible in Python? What do you think is the best approach?</p>

<p>I'm trying to play with the setInterval method and I'm just wondering what I have done wrong here. If I program it to return an alert, no problem - it appears at every interval as expected. However, I want my background color to change every few seconds and it's not happening. The color is altered once and that's all the fun I get.</p>
<p><a href="https://i.stack.imgur.com/2w0Ta.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2w0Ta.png" alt="enter image description here" /></a></p>
<p>I've had a look at similar posts on Stack Overflow and played around, but to no avail. Any suggestions much appreciated. Thanks million!</p>

<p>can anyone please help me?, I created a login function with api, when the user wants to login and succeeds then it is directed to the profilescreen the user details appear, but when it switches to the homescreen and switches to the profilescreen again, the user details that previously appeared are lost and become null.</p>
<p>I thought of using sharedpreferences to save user response data after login, but I don't know if it was saved or not</p>
<pre><code>Future<LoginModels> postLogin(String email, String password) async {
var dio = Dio();
String baseurl = url;
Map<String, dynamic> data = {'email': email, 'password': password};
try {
final response = await dio.post(
'$baseurl/api/login',
data: data,
options: Options(headers: {'Content-type': 'application/json'}),
);
print('Respon -> ${response.data} + ${response.statusCode}');
if (response.statusCode == 200) {
final loginModel = LoginModels.fromJson(response.data);
return loginModel;
}
} catch (e) {
print('Error di $e');
}
return LoginModels();}
</code></pre>
<p>i tried adding sharedpreference in the part after response.statuscode == 200 , like this</p>
<pre><code> SharedPreferences pref = await SharedPreferences.getInstance();
String jsonUser = jsonEncode(loginModel);
pref.setString('userDetail', jsonUser);
print('data nih $jsonUser');
</code></pre>
<p>and the output is like this

<p>I have tried to switch values, numbers, variables, everything, and nothing seems to work. I am still quite new to arrays so I apologize if it is a simple fix.</p>
<p>The nested loop is supposed to find the smallest value in the array and then return it to the main method, however, every time I just get the first number in the array.
code:</p>
<pre><code> public static void main(String[] args) {
int[] arr = {2, 1, 4, 3, 6, 5, 8, 7};
int min;
min = findMin(arr);
System.out.println("Smallest value: " + min);
}
public static int findMin(int[] arr) {
int min = arr[0];
for (int i = 0; i < arr.length; i++) {
if (arr[i] < min) ;
{
min = arr[i];
}
}
return arr[min];
}
</code></pre>

<p>I have created a docker image from a spring application but there's an error where it's not able to access mysql database and I am having issues solving this.</p>
<p>I created an image using Dockerfile</p>
<pre><code>FROM openjdk:17-jdk-alpine

<p>I am not sure what to do next.</p>
<p>I am expecting for spring application to link with mysql</p>

<p>I am trying to click 1 Min button on this <a href="https://www.investing.com/technical/technical-analysis" rel="nofollow noreferrer">site</a></p>
<p>below is my python code</p>
<pre><code>url = 'https://www.investing.com/technical/technical-analysis'
driver.get(url)
events = WebDriverWait(driver, 30).until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, "section#leftColumn")))
print("Required elements found")
events.find_element(By.XPATH,"//a[text()='1 Min']").click()
</code></pre>
<p>Am getting the following error:
events.find_element(By.XPATH,"//a[text()='1 Min']").click()
AttributeError: 'list' object has no attribute 'find_element'</p>
<p>What can I change in the code to click the '1 Min' button succesfully?</p>

<p>I have looked for the past hour at least but to no avail. I'm writing a text based adventure game and I have an ArrayList storing my inventory. I am currently working on a "displayInventory" method which simply prints the inventory to console.</p>
<pre><code>public void displayInventory()
{
StringBuilder result = new StringBuilder("Inventory: \n");
String format = ("%s, %s, %s %n");
for (int i=0; i< inventory.size(); i++)
{
result.append(inventory.get(i));
}
//String result = String.join("," inventory);
System.out.format(format, result.toString());;
}
</code></pre>
<p>Now initially my issue was figuring out how to use it with StringBuilder but now I sort of have that down. But I've run into the issue where I've set the format to three strings(items from inventory) to be printed to each line. After testing it with only two items I get the errors below (which makes sense).</p>
<pre><code>Inventory:
Small BottleLarge Bottle, Exception in thread "main" java.util.MissingFormatArgumentException: Format specifier '%s'
at java.base/java.util.Formatter.format(Formatter.java:2688)
at java.base/java.io.PrintStream.format(PrintStream.java:1209)
at wonderland/gameObjects.Player.displayInventory(Player.java:41)
at wonderland/gameObjects.Test.main(Test.java:19)
</code></pre>
<p>Do I need to set up some sort of check to see if there is a multiple of three items in the players inventory and have different print statements/formats if not? Is there a way to format an unknown amount (or at least a varying amount) of strings?</p>
<p>The player could pick three items up, use one, then pick up another two. I need some way of displaying the varying amount of items that could be in their inventory.</p>
<p>I hate asking questions on SO because they almost always get declared duplicates, despite no case being identical. So I was really hesitant but couldn't take the head trauma any longer. Thank you in advance for any and all help/answers.</p>

<p>I have a string, for example:</p>

</code></pre>
<p>And I have a list equal in length to the number of <code>?</code> in the string:</p>
<pre><code>l = ['1', '2', '3']
</code></pre>
<p>What is a pythonic way to return <code>s</code> with each consecutive <code>?</code> replaced with the values in <code>l</code>?, e.g.:</p>
<pre><code>s_new = 'I 1 am 2 a 3 string'

<pre><code> System.out.println("Year 1: No comperison");
for (int i = 0; i < revenues.size(); i = i + 1){

<p>I am having difficulty figuring out to make user-entered lists of numbers equal a quadrilateral, specifically a rhombus and square, in Python. I do not know if my code needs a function or loops or if/else statements to know if it is a rhombus or square.</p>
<p>So far, I have this, but I can't figure out how to go through each side to find out if they are equal to each other or if angle 1 equals angle 2, etc. Which afterwards, I would determine if it the numbers that the user entered made a list that equaled a rhombus or square. Excuse the confusing sentences, I tried to make my problem as clear as possible. Thank you for taking your time to help, if you do!</p>
<p>Edit: I tried a function, but found that it was too complicated by itself. I want to figure out how to search through each list's elements and make sure that they equal/match each other. Thank you!</p>
<p>A rhombus has</p>
<ol>
<li>All four sides the same length</li>
<li>Angle 1 equals Angle 3</li>
<li>Angle 2 equals Angle 4</li>
</ol>
<p>A square has</p>
<ol>
<li>All four sides the same length.</li>
<li>All angles equal to each other</li>
</ol>
<pre><code>while True:
# Input, Validation, Repetition
print("=== Please enter Sides ===\n")
sList = [] # list for sides
for i in range(0,4,1):
sides = float(input("Please enter side %i : " %(i + 1 ) ) )
if sides < 0:
sides = float(input("Value must be positive! Please enter side %i : " %(i + 1 )))
sList.append(sides)
print()
print("=== Please enter angles ===\n")
aList = [] # list for angles
for i in range(0,4,1):
angles = float(input("Please enter angle %i : " %(i + 1 ) ) )

# Rhombus
if sList == sList and aList[1] == aList[3] and aList[2] == aList[4]:
print("This is a rhombus\n")
#Square

print("This is a square!\n")

error={touched.active && Boolean(errors.active)}
>
<MenuItem value={true}>Yes</MenuItem>

<p>I am evaluating frequencies using sample data in the snipped file below.</p>
<p>I have noticed that with an unordered list, the evaluation takes less than a second to return a result. However, with a vector, it takes almost a whole minute to evaluate it!</p>
<p>There are several factors I considered:</p>
<ul>
<li>Size of the data</li>
<li>The data itself</li>
</ul>
<p>After several experiments, I found that if I took out the 2nd to last data (-6) the performance is almost identical and results are returned for both in less than a second!</p>
<p><a href="https://i.stack.imgur.com/zi2s7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zi2s7.png" alt="result immediate" /></a></p>
<p>However, if I include the -6, the vector evaluation takes too long!</p>
<p><a href="https://i.stack.imgur.com/SmOXB.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SmOXB.png" alt="result bad" /></a></p>
<p>I tried changing the number like -5, -4, etc. and the performance was actually pretty good!</p>
<p><a href="https://i.stack.imgur.com/Cep6V.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Cep6V.png" alt="result good" /></a></p>
<p>For some reason, only -6 before the last data/number (+125503) in the file seems to be affecting the vector performance...what's going on?</p>
<p><strong>Note:</strong> of course, I tried running them individually too by commenting out the unorderedlist logic and then the vector logic, same behavior</p>
<p><strong>code:</strong></p>
<pre><code>#include <algorithm>
#include <unordered_set>
#include <fstream>
#include <iostream>
#include <vector>
using namespace std;
vector<int> scanFile(ifstream &file) {
vector<int> scannedFile;
string str;
while (getline(file, str)) {
scannedFile.push_back(stoi(str));
}
return scannedFile;
}
int main() {
ifstream inputFile;
vector<int> fileInfo;
string str = "";
inputFile.open("file.txt");
fileInfo = scanFile(inputFile);
inputFile.close();
int Occurrences = 0;
unordered_set<int> unordrdList; //results are immediate, even with -6!
bool found = false;
unordrdList.insert(Occurrences);
while (!found) {
for (int n : fileInfo) {
Occurrences += n;
found = unordrdList.find(Occurrences) != unordrdList.end();
unordrdList.insert(Occurrences);
if (found) {
cout << "Using Unordered_Set: The 2nd showing #: " << to_string(Occurrences) << endl;
break;
}
}
}
int Occurrnce = 0;
vector<int> vectr; //result takes too long with -6 present in the file before 2nd to last line!
bool found2 = false;
vectr.push_back(Occurrnce);
while (!found2) {
for (int n : fileInfo) {
Occurrnce += n;
found2 = find(vectr.begin(), vectr.end(), Occurrnce) != vectr.end();
vectr.push_back(Occurrnce);
if (found2) {
cout << "Using Vector: The 2nd showing #: " << to_string(Occurrnce) << endl;
break;
}
}
}
}

<p>I’m trying to click on a button that has the same class as other 5 buttons.</p>
<p>This code is working but clicks on the first button that finds the class.</p>
<pre><code>WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, ".com-ex-5"))).click()
</code></pre>
<p>How can I click on the 5th button?</p>
<p>This ain’t working :</p>
<pre><code>WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, ".com-ex-5")))[5].click()

<p>I require a column which counts the number days i.e(Order Date - 01Jan2020).</p>
<p><strong>Condition is</strong> -> if Order Date lies between 01Jan2020 and 31Mar2020
then (DATE_DIFF('2020-01-31' ,Order Date, DAY))
else 0<br />
Question -> how to use this condition statement in BigQuery ?</p>
<p><strong>Table</strong> -
Customer ID | Order Date
298 | 2020-02-28
78 | 2020-04-02
31 | 2021-01-09
345 | 2021-09-09
74 | 2020-01-20</p>
<p>I tried -</p>
<pre><code>if((Order Date <'2020-01-01') and (Order Date >'2020-03-31'),(DATE_DIFF('2020-01-31' ,Order Date, DAY)

<p>I can see GKE, AKS, EKS all are having nodepool concepts inbuilt but Kubernetes itself doesn't provide that support. What could be the reason behind this?</p>
<p>We usually need different Node types for different requirements such as below-</p>
<p>Some pods require either CPU or Memory intensive and optimized nodes.
Some pods are processing ML/AI algorithms and need GPU-enabled nodes. These GPU-enabled nodes should be used only by certain pods as they are expensive.
Some pods/jobs want to leverage spot/preemptible nodes to reduce the cost.</p>
<p>Is there any specific reason behind Kubernetes not having inbuilt such support?</p>

<p>In MongoDB (using <code>mongosh</code> or command-line mongo cli), you can query documents, for example using <code>db.mycollection.find({"something":true})</code> and get the following result:</p>
<pre class="lang-json prettyprint-override"><code>{
"someDate": ISODate("2022-10-24T17:21:44.980Z"),
"something": true,
"hello": "world"
}
</code></pre>
<p>This result, however, is not valid JSON (Due to <code>ISODate</code>). How can I change the query above to make MongoDB return canonical (valid) JSON?</p>
<p>I'm looking for a recursive and generalized way to do this, even for deeply nested documents.</p>

<p>We want to remind users to complete their workflow. These workflow events look like 'Workflow started', 'progressed stage 1', 'progressed stage 2',... 'Workflow ended' and they flow through Kafka. Each event has a unique identifier to identify a workflow attempt by the user.</p>
<p>How do we design a pipeline in Flink to detect workflows that have started but abandoned in the middle? Is there any established pattern for this?</p>

<p>I have a class in Python that initializes the attributes of an environment. I am attempting to grab the topographyRegistry attribute list of my Environment class in a separate function, which when called, should take in the parameters of 'self' and the topography to be added. When this function is called, it should simply take an argument such as addTopographyToEnvironment(self, "Mountains") and append it to the topographyRegistry of the Environment class.
When implementing what I mentioned above, I ran into an error regarding the 'self' method not being defined. Hence, whenever I call the above line, it gives me:</p>
<pre><code> print (Environment.addTopographyToEnvironment(self, "Mountains"))
^^^^
NameError: name 'self' is not defined
</code></pre>
<p>This leads me to believe that I am unaware of and missing a step in my implementation, but I am unsure of what that is exactly.
Here is the relevant code:</p>
<pre><code>class EnvironmentInfo:
def __init__(self, perceivableFood, perceivableCreatures, regionTopography, lightVisibility):
self.perceivableFood = perceivableFood
self.perceivableCreatures = perceivableCreatures
self.regionTopography = regionTopography
self.lightVisibility = lightVisibility
class Environment:
def __init__(self, creatureRegistry, foodRegistry, topographyRegistery, lightVisibility):
logging.info("Creating new environment")
self.creatureRegistry = []
self.foodRegistry = []
self.topographyRegistery = []
self.lightVisibility = True
def displayEnvironment():
creatureRegistry = []
foodRegistry = []
topographyRegistery = ['Grasslands']
lightVisibility = True
print (f"Creatures: {creatureRegistry} Food Available: {foodRegistry} Topography: {topographyRegistery} Contains Light: {lightVisibility}")
def addTopographyToEnvironment(self, topographyRegistery):
logging.info(
f"Registering {topographyRegistery} as a region in the Environment")
self.topographyRegistery.append(topographyRegistery)
def getRegisteredEnvironment(self):
return self.topographyRegistry
if __name__ == "__main__":
print (Environment.displayEnvironment()) #Display hardcoded attributes
print (Environment.addTopographyToEnvironment(self, "Mountains"))#NameError
print (Environment.getRegisteredEnvironment(self)) #NameError
</code></pre>
<p>What am I doing wrong or not understanding when using 'self'?</p>
<p>Edit: In regard to omitting 'self' from the print statement, it still gives me an error indicating a TypeError:</p>
<pre><code> print (Environment.addTopographyToEnvironment("Mountains"))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Environment.addTopographyToEnvironment() missing 1 required positional argument: 'topographyRegistery'
</code></pre>

<p>The IDE I used is Clion.
I wanna read the Line-separated data stored in .txt file.
Each line contains firstname, surname, gender, ID and age, which are str, str, str, int and int.</p>
<p>StudentList.txt</p>
<pre class="lang-none prettyprint-override"><code>Olivia SWANSON F 29001 20
Emma ONEILL F 7900 19
</code></pre>
<p>I try to use <code>fscanf</code> to read the data.</p>
<pre><code>FILE *fp;
char fname[20];
char sname[20];
char gender[1];
int ID;
int age;
fp = fopen("C:\\Users\\Catlover\\Desktop\\DSA\\Program2\\StudentList.txt", "r");
while(fscanf(fp, "%s %s %s %d %d", fname, sname, gender, &ID, &age)!= EOF)
{
printf("%s,%s,%s,%d,%d\n", fname, sname, gender, ID, age);
}
fclose(fp);
return 0;
</code></pre>
<p>But the result it return looks like a little bit weird becasue it doesn't output the second value.</p>
<p>Result is</p>
<pre class="lang-none prettyprint-override"><code>Olivia,,F,29001,20
Emma,,F,7900,19
</code></pre>
<p>Something shocks me is that the same code runned in PellesC lead to the correct result.</p>
<p>I used to learn C++ so there may exists some important rules in C but I didn't notice. Can anyone show that for me?</p>

<p>I want to create a json string that contains a list of long values with the following structure:
{"document_ids":[23461504,20639162,20395579]}</p>
<p>I solved the problem with the line below, but I feel like I could do it with a cleaner command(string.Format).</p>
<pre><code>var json = "{\"document_ids\":" + JsonConvert.SerializeObject(My List<long>) + "}";
</code></pre>
<p>But the command I write with string.Format gives an error message.</p>
<pre><code>var json = string.Format("{\"document_ids\":{0}}", JsonConvert.SerializeObject(My List<long>));
</code></pre>
<p>I get this error message.
System.FormatException: 'Input string was not in a correct format.'</p>

<p>Another total noob question: I am not sure why my answer is printing out as a decimal. Also, in the lab the dimes are expected to be listed first, not sure how I screwed that up? I appreciate the help!</p>
<p>Define a function called exact_change that takes the total change amount in cents and calculates the change using the fewest coins. The coin types are pennies, nickels, dimes, and quarters. Then write a main program that reads the total change amount as an integer input, calls exact_change(), and outputs the change, one coin type per line. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Output "no change" if the input is 0 or less.</p>
<p>Your program must define and call the following function. The function exact_change() should return num_pennies, num_nickels, num_dimes, and num_quarters.
def exact_change(user_total)</p>
<pre><code>def exact_change(user_total):
return(num_dollars, num_quarters, num_dimes, num_nickles, num_pennies)
if __name__ == '__main__':
input_val = float(input())
num_dollars = input_val // 100
rem=input_val % 100
num_quarters = rem // 25
rem = rem % 25
num_dimes = rem // 10
rem = rem % 10
num_nickles = rem // 5
rem = rem % 5
num_pennies = rem
if input_val <= 0:
print("no change")
else:
num_dollars = input_val // 100
conv_dollar = str(num_dollars)
rem = input_val % 100
if num_dollars == 1:
print(conv_dollar + ' dollar')
elif num_dollars > 1:
print(conv_dollar + ' dollars')
num_quarters = rem // 25
conv_quarter = str(num_quarters)
rem = rem % 25
if num_quarters == 1:
print(conv_quarter + ' quarter')
elif num_quarters > 1:
print(conv_quarter + ' quarters')
num_dimes = rem // 10
conv_dime = str(num_dimes)
rem = rem % 10
if num_dimes == 1:
print(conv_dime + ' dime')
elif num_dimes > 1:
print(conv_dime + ' dimes')
num_nickels = rem // 5
conv_nickel = str(num_nickels)
rem = rem % 5
if num_nickels == 1:
print(conv_nickel + ' nickel')
elif num_nickels > 1:
print(conv_nickel + ' nickels')
num_pennies = rem
conv_penny = str(num_pennies)
rem = rem % 1
if num_pennies == 1:
print(conv_penny + ' penny')
elif num_pennies > 1:
print(conv_penny + ' pennies')

<p>Trying to query an oracle db table having date in format: <code>2022-06-22T12:25:06.087</code> (<code>LocalDateTime.now().toString()</code>). Column type for created_time is varchar2.
Trying to query for data between two dates. I have tried the following but it results in error "date format not recognized":</p>
<pre><code>select * from MY_TABLE
where to_date(created_time, 'yyyy-MM-ddTHH:mm:ss.SSS')
between to_date('2022-07-03T10:15:06.091', 'yyyy-MM-ddTHH:mm:ss.SSS')
and to_date('2022-07-03T10:15:06.091', 'yyyy-MM-ddTHH:mm:ss.SSS');
</code></pre>
<p>Can anyone help me correct this query?</p>

<p>The main problem my code doesn't do echo every time(fibonacci sequence)</p>
<pre><code>#!/bin/bash
function fib(){
if [ $1 -le 0 ]; then
echo 0
elif [ $1 -eq 1 ]; then
echo 1
else
echo $[`fib $[$1 - 2]` + `fib $[$1 - 1]` ]
fi
}
fib $1
</code></pre>
<p>i was expecting it will do echo every time. It shows:</p>
<pre><code>~/Bash$ ./fn.sh 12
144
</code></pre>
<p>but i need it to show like this:</p>
<pre><code>~/Bash$ ./fn.sh 12
0
1
1
2
3
5
8
13
21
34
55

<p>I have a date which is a string and looks like this:</p>
<pre><code>String day = "30-11-2022 12:27";
</code></pre>
<p>I am trying to convert the above string to DateTime object and convert the 24hr time to 12hr. I am using the following code:</p>
<pre><code>DateFormat("dd-MM-yyyy hh:mm a").parse(day);
</code></pre>
<p>It was working before but today the parsing is causing format exception error. The error message is shown below:</p>
<pre><code>[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: FormatException: Trying to read from 30-11-2022 12:27 at position 17
</code></pre>
<p>Why am I getting error while parsing now? How to fix it?</p>

<p>I observed a weird behavior while experimenting with a PLINQ query. Here is the scenario:</p>
<ul>
<li>There is a source <code>IEnumerable<int></code> sequence that contains the two items 1 and 2.</li>
<li>A Parallel LINQ <a href="https://learn.microsoft.com/en-us/dotnet/api/system.linq.parallelenumerable.select" rel="nofollow noreferrer"><code>Select</code></a> operation is applied on this sequence, projecting each item to itself (<code>x => x</code>).</li>
<li>The resulting <code>ParallelQuery<int></code> query is consumed immediately with a <code>foreach</code> loop.</li>
<li>The <code>selector</code> lambda of the <code>Select</code> projects successfully the item 1.</li>
<li>The consuming <code>foreach</code> loop throws an exception for the item 1.</li>
<li>The <code>selector</code> lambda throws an exception for the item 2, after a small delay.</li>
</ul>
<p>What happens next is that the consuming exception is lost! Apparently it is shadowed by the exception thrown afterwards in the <code>Select</code>. Here is a minimal demonstration of this behavior:</p>
<pre><code>ParallelQuery<int> query = Enumerable.Range(1, 2)
.AsParallel()
.Select(x =>
{
if (x == 2) { Thread.Sleep(500); throw new Exception($"Oops!"); }
return x;
});
try
{
foreach (int item in query)
{
Console.WriteLine($"Consuming item #{item} started");
throw new Exception($"Consuming item #{item} failed");
}
}
catch (AggregateException aex)
{
Console.WriteLine($"AggregateException ({aex.InnerExceptions.Count})");
foreach (Exception ex in aex.InnerExceptions)
Console.WriteLine($"- {ex.GetType().Name}: {ex.Message}");
}
catch (Exception ex)
{
Console.WriteLine($"{ex.GetType().Name}: {ex.Message}");
}
</code></pre>
<p>Output:</p>
<pre class="lang-none prettyprint-override"><code>Consuming item #1 started
AggregateException (1)
- Exception: Oops!
</code></pre>
<p><a href="https://dotnetfiddle.net/ggamsF" rel="nofollow noreferrer">Live demo</a>.</p>
<p>Chronologically the consuming exception happens first, and the PLINQ exception happens later. So my understanding is that the consuming exception is more important, and it should be propagated with priority. Nevertheless the only exception that is surfaced is the one that occurs inside the PLINQ code.</p>
<p><strong>My question is:</strong> why is the consuming exception lost, and is there any way that I can fix the query so that the consuming exception is propagated with priority?</p>
<p>The desirable output is this:</p>
<pre class="lang-none prettyprint-override"><code>Consuming item #1 started
Exception: Consuming item #1 failed
</code></pre>
