74,170,940 | <p>I know the difference between the two clearly.</p>
<p>Concurrency is performing multiple tasks alternately, while parallelism is performing multiple tasks at once.</p>
<p>However, there is confusion in this code because a certain instructor has a different opinion than me.</p>
<p>Here is code:</p>
<pre class="lang-java prettyprint-override"><code>public static void main(String[] args) throws InterruptedException {
Thread t1 = new Thread(() -> System.out.println("T1"));
Thread t2 = new Thread(() -> System.out.println("T2"));
t1.start();
t2.start();
t1.join();
t2.join();
}
</code></pre>
<p>I thought that running this code on <code>multiple cores</code> would run with parallelism, not concurrency, the instructor says concurrency.</p>
<p>If concurrency is not parallel, what is the reason?</p>

74,170,964 | <p>Currently it does it with a color, if I wanted to use an image instead, how would that be done?</p>
<p>It works fine using a color as you can see, how would I be able to use an image here, where it breaks apart the same way, in 4 triangle shapes?</p>
<p>How would this be done?</p>
<p>Clicking on the play button causes it to split into 4 triangle shapes.</p>

74,171,020 | <p>I need help with the Google Sheet formula.
I am trying to combine the array formula with vlookup and import range to get specific values from three columns from two different sheet</p>
<p>For example, if you write c15, it will look for this specific value in the first or the second sheet. When finding it, it will get the value from the chosen columns and write it in the new sheet. The formula works perfectly with one file, but I want the formula to vlookup within the two sheets</p>
<p>This is the formula</p>
<pre><code>=ArrayFormula(VLOOKUP(C4,IMPORT RANGE("URL","Autoparts!A:AC"),{5,29,10},0))
</code></pre>
<p><code>C4</code> is the cell that has the value I'm looking for.
<code>{5,29,10}</code> These are the columns where to look for the needed values.</p>
<p>Any help is appreciated.</p>

74,171,081 | <p>I have a <code>m by n</code> matrix in matlab and want to find the indices (row, column) of each antidiagonal elements. For example for a <code>4x3</code> matrix, I would like to have the following indices:</p>
<pre><code>antidiag1 = (1,1)
antidiag2 = (2,1) , (1,2)
antidiag3 = (3,1) , (2,2), (1,3)
antidiag4 = (4,1) , (3,2), (2,3)
antidiag5 = (4,2) , (3,3)
antidiag3 = (4,3)

<p>in the above example <code>(m,n)=(row, column)</code>. To show what I mean by anti-diagonal elements see the below matrix in which red lines are anti-diagonals</p>

I have looked at all the other answers on the forum, but none of them work during my testing (on Windows). For C++, I have the working code in <strong>Fig 1</strong>, however when converting the code to C and assigning the strings to a variable I get the error <code>\u001b is not a valid universal character</code> (<strong>Fig 2</strong>).</p>
<p><strong>Fig 1</strong></p>
<pre class="lang-cpp prettyprint-override"><code>namespace Fore {

74,171,204 | <p>Pretty new to C#.</p>
<p>I want to read the user input from a combo box and use the selected currencies in a method which converts one to another. The output isn't in console, it's on a Windows form.</p>
<p>This is my combo box input read code:</p>
<pre><code>public void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
double first = comboBox1.SelectedIndex;
}
public void comboBox2_SelectedIndexChanged(object sender, EventArgs e)
{
double second = comboBox2.SelectedIndex;
}

<p>And this is my code that uses the selected indexes and converts them:</p>
<pre><code>internal class Currencies
{
public double[] Convert(double[] currencies, int amount)
{
double[] convertedAmount = new double[currencies.Length];
if (Converter.comboBox1.first == HRK && Converter.comboBox2.second == EURO)
{
int exchangeRate1 = 1;
double exchangeRate2 = 7.4;
for (int i = 0; i < currencies.Length; i++)
{
convertedAmount[i] = amount * exchangeRate1 / exchangeRate2;
}
}
else if (Converter.comboBox1.first == EURO && Converter.comboBox2.seocnd == HRK)
{
int exchangeRate1 = 1;
double exchangeRate2 = 7.4;
for (int i = 0; i < currencies.Length; i++)
{
convertedAmount[i] = amount * exchangeRate1 / exchangeRate2;
}
}
else
{
throw new NotSupportedException();
}
return convertedAmount;
}
}
</code></pre>
<p>Why doesn't the method let me use the variables "first" and "second" where I stored the selected indexes to convert the currencies?</p>

74,171,322 | <p>I have a question regarding the combination of SwiftUI and MVVM.</p>
<p>Before we start, I have read some posts discussing whether the combination of SwiftUI and MVVM is necessary. But I don't want to discuss this here, as it has been covered elsewhere. I just want to know if it is possible and, if yes, how. :)</p>
<p>So here comes the code. I tried to add the ViewModel Layer in between the updated Object class that contains a number that should be updated when a button is pressed. The problem is that as soon as I put the ViewModel Layer in between, the UI does not automatically update when the button is pressed.</p>
<p><strong>View</strong>:</p>
<pre><code>
struct ContentView: View {
@ObservedObject var viewModel = ViewModel()
@ObservedObject var numberStorage = NumberStorage()
var body: some View {
VStack {
// Text("\(viewModel.getNumberObject().number)")
// .padding()
// Button("IncreaseNumber") {
// viewModel.increaseNumber()
// }
Text("\(numberStorage.getNumberObject().number)")
.padding()
Button("IncreaseNumber") {
numberStorage.increaseNumber()
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
</code></pre>
<p><strong>ViewModel</strong>:</p>
<pre><code>
class ViewModel: ObservableObject {
@Published var number: NumberStorage
init() {
self.number = NumberStorage()
}
func increaseNumber() {
self.number.increaseNumber()
}
func getNumberObject() -> NumberObject {
self.number.getNumberObject()
}
}
</code></pre>
<p><strong>Model</strong>:</p>
<pre><code>
class NumberStorage:ObservableObject {
@Published var numberObject: NumberObject
init() {
numberObject = NumberObject()
}
public func getNumberObject() -> NumberObject {
return self.numberObject
}
public func increaseNumber() {
self.numberObject.number+=1
}
}
struct NumberObject: Identifiable {
let id = UUID()
var number = 0
} ```
Looking forward to your feedback!

74,171,420 | <p>I am attempting to create a probability density function of <strong>times</strong> from an array of Timestamp tuples. I do not care about the date aspect of the timestamp and I would like to use only the hour and minute fields of the timestamp. I do not mind switching to R or Julia if need be since the time data types in Python seem to be restricting this. I attempted setting all the dates to 00:00 but that did not work. In the end I want a pdf of the first tuple values and then a pdf of the difference between each tuple 2nd and 1st value.
Can someone please give direction or a solution?</p>

74,171,427 | <p>So the template of my code looks like this :</p>
<pre><code>class Foo:
def __init__(self, params):
self.params = params #a dictionary
def recursive_iteration(self, buffer):
if buffer :
#do something
self.params['new_field'] = "new_value"
else :
for i in range(2):
new_params = self.params
new_params['some_field'] = another_value #changing with i
Foo(new_params).recursive_iteration(True)
</code></pre>
<p>The problem I encounter is that when <code>recursive_iteration</code> is called inside another <code>recursive_iteration</code> then there are two <code>self</code> variables that exist within a different (but nested) scope.</p>
<p>And during the second iteration of the for loop (i=1):
<code>self.params</code> has the field 'new_field' which means the outer scope self was the one modified.</p>
<p>Did i just flaw my code and should rework the model ?(I could go functional only but this is partially existing code)</p>
<p>My question is : Can I precise which <code>self</code> I want to be modified with regard to their scope?</p>
<p>EDIT : The issue comes from the shallow copy of self.params. All the time the same dictionnary is modified. It's not about the scope of the variables.
Change <code>new_params = self.params</code> to <code>new_params = self.params.copy()</code> to solve the issue.</p>

i write this code -</p>
<pre><code>unsigned int left_rottate(unsigned int a, int b){
int temp;
int bits_size = size_in_bits()-1;
b %= bits_size;
while(b > 0){
temp = (a>> bits_size)&1;
a = (a <<1) | temp;
b--;
}
return a;
}
int size_in_bits()

unsigned int x,
i = 0;
x = ~0u;
while ((x & 1) != 0)
(i+= 1, x /= 2);
return (int) i;

74,171,509 | <p>There is probably a term for what I want to do, I will edit my question with the proper term when I find it out.</p>
<p>Assume 3 lists:</p>
<pre><code>a = ["alpha", "beta", gamma"]
b = ["a", "b", "c", "d"]
c = ["one", "two", "three" "four", "five"]
</code></pre>
<p>My custom base has the following sequence:</p>
<pre><code>alpha-a-one, alpha-a-two, ..., alpha-a-five, alpha-b-one, ..., alpha-d-five, beta-a-one, ..., gamma-d-five
</code></pre>
<p>I want to be able to define <code>num1</code> and <code>num2</code> so that I can calculate addition and subtraction. For example</p>
<pre><code>>>> num1 = alpha-b-two
>>> num2 = alpha-a-four
>>> num1-num2
3
</code></pre>
<p>and</p>
<pre><code>>>> num = alpha-a-four
>>> num+3
alpha-b-two
</code></pre>
<p>How can I do that? (and what is the term for this?)</p>

74,171,526 | <p>I want to convert the following for loop to a list comprehension:</p>
<pre><code> for f in src_files.copy(): # Iterate over a list of images
if os.path.getsize(os.path.join(SOURCE_DIR, f)) == 0: # Check if filesize is 0
print("filename is zero length, so removing.")
src_files.remove(f) # Remove corrupted files from list
</code></pre>
<p>I had a look a various different other list comprehension questions and came up with this:</p>
<pre><code>src_files = [f for f in src_files if os.path.getsize(os.path.join(SOURCE_DIR, f)) > 0]
</code></pre>
<p>So this is working fine but it does not include the print of the else statement. Apparently you have to change the position of the condition if you use an else statement for some reason. So I tried this:</p>
<pre><code>src_files = [f if os.path.getsize(os.path.join(SOURCE_DIR, f)) > 0 else print("filename is zero length, so removing.") for f in src_files]
</code></pre>
<p>This does not give me an error but it simply does nothing. The list remains the same as before. I don't get it. Why does the if condition stop working just because I added a print in the else statement?</p>
<p>(The reason why I want to rewrite the existing code is because I have an enourmous amount of images - hundreds of gigabytes - that need to be processed and I want to make the code as fast as possible)</p>

74,171,535 | <p>I'm having trouble configuring localization in my asp.net 7.0 MVC project.
Configuration:</p>
<pre><code>.AddLocalization(opts => opts.ResourcesPath = "Resources")
</code></pre>
<p>then</p>
<pre><code>CultureInfo[] supportedCultures = new[]
{
new CultureInfo("en-US"),
new CultureInfo("bg-BG")
};
mvcBuilder
.AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix)
.AddDataAnnotationsLocalization();
mvcBuilder
.Services
.Configure<RequestLocalizationOptions>(options =>
{
options.DefaultRequestCulture = new RequestCulture(culture: "en-US", uiCulture: "en-US");
options.SupportedCultures = supportedCultures;
options.SupportedUICultures = supportedCultures;
});
</code></pre>
<p>This is called before</p>
<pre><code>.AddRazorPages();
</code></pre>
<p>And at the end</p>
<pre><code>app.UseRequestLocalization(app.Services.GetRequiredService<IOptions<RequestLocalizationOptions>>().Value);
</code></pre>
<p>I have installed Microsoft.Extensions.Localization nuget.
I have two resource files in folder Resources</p>
<ul>
<li>Controllers.HomeController.bg-BG.resx</li>
<li>Controllers.HomeController.en-US.resx</li>
</ul>
<p>In both resources there is entry "title" with some values
Injected IStringLocalizer into HomeController but everytime it returns only "title", used it like this:</p>
<pre><code>this.stringLocalizer["title"].Value
</code></pre>
<p>After hours of trial and error I really can't seem to find what's the problem.</p>

74,171,585 | <p>I'm using pgsql to find the cage number (cno) that holds the largest number of animals but doesn't have a bird in it.</p>
<p>The way I tried to do it is by creating a table that counts the number of animals in each cage (not including those with birds) and then return the ones where the count equals the max value.</p>
<pre><code>select temp.cno,temp.size
from
(select cage.cno,cage.size,count(*) as q
from cage,animal
where cage.cno = animal.cno and cage.cno not in (select cno from animal where lower(atype)='sheep')
group by cage.cno,cage.size) as temp
where temp.q = (select max(q) from temp)
</code></pre>
<p>I'm getting the following error message</p>
<pre><code>ERROR: relation "temp" does not exist
LINE 7: where temp.q = (select max(q) from temp)
</code></pre>
<p>Any idea how to overcome this issue? Why isn't temp recognized within the last sub query?</p>
<p>Here are the tables</p>
<ol>
<li><p>cage (<strong>cno</strong>, type, size)</p>
</li>
<li><p>animal (<strong>aid</strong>, aname, cno, atype)</p>

74,171,741 | <p>I'm trying to create a table with : <code>Etudiant::create($request->all());</code>
But actually there is some field that I don't need from the requedt but I need them for another table; So I'm wondering if there is a function or something to add an exception to the <code>->all()</code></p>

74,171,770 | <p>I have the following dataset df.
For each id, a1-a3 are the values of variable a recorded at time points 1-3. b1-b3 are the values of variable b recorded at time 1-3. c is a time-invariant variable.</p>
<p>Here is the codes to create the dataset:</p>
<pre><code>id <- c(1, 2, 3)
a1 <- c(52, 339, 83)
a2 <- c(86, 746, 35)
a3 <- c(46, 546, 45)
b1 <- c(84, 45, 83)
b2 <- c(55, 46, 35)
b3 <- c(46, 60, 45)
c <- c(30, 20, 50)
df <- cbind(id, a1, a2, a3, b1, b2, b3, c)
</code></pre>
<p>Here is original dataset df</p>
<pre><code> id a1 a2 a3 b1 b2 b3 c
[1,] 1 52 86 46 84 55 46 30
[2,] 2 339 746 546 45 46 60 20
[3,] 3 83 35 45 83 35 45 50
</code></pre>
<p>I want to change it to the long format, i.e., into the following df2</p>
<pre><code> time id a b c
[1,] 1 1 52 84 30
[2,] 2 1 86 55 30
[3,] 3 1 46 46 30
[4,] 1 2 339 45 20
[5,] 2 2 746 46 20
[6,] 3 2 546 60 20
[7,] 1 3 83 83 50
[8,] 2 3 35 35 50
[9,] 3 3 45 45 50
</code></pre>
<p>What is the best way to do that?</p>
<p>I tried pivot_longer Function (tidyr Package), but it does not return what I need.</p>
<p>Thank you very much for the help!</p>

74,171,988 | <p>please I'm solving one problem (just learning purposes). I'm using <code>useState()</code> hook and then, after some timeout I want add next items into array from remote fetch.</p>
<p>My code snippet look like:</p>
<pre class="lang-js prettyprint-override"><code>const [tasks, setTasks] = useState([]);
const url = 'https://pokeapi.co/api/v2/pokemon?offset=0&limit=5';
// asnynchronous call. Yes, it's possible to use axios as well
const fetchData = async () => {
try {
let tasksArray = [];
await fetch(url)
.then((response) => response.json())
.then((data) => {
data.results.map((task, index) => {
// first letter uppercase
const taskName = task.name.charAt(0).toUpperCase() + task.name.slice(1);
tasksArray.push({ id: index, name: taskName });
});
});
console.log('Added tasks:' + tasks.length);
setTasks(_.isEmpty(tasks) ? tasksArray : [...tasks, tasksArray]);
} catch (error) {
console.log('error', error);
}
};
useEffect(() => {
// Add additional example tasks from api after 5 seconds with
// fetch fetchData promise
setTimeout(fetchData, 5000);
}, []);
</code></pre>
<p>Code works fine with <code>useEffect()</code> hook. But in <code>async</code> function my array is empty when I add some tasks within five seconds and it will be replaced by fetched data and one empty</p>
<p>I added <strong>Butter</strong> and <strong>Milk</strong> within 5 seconds to my Shopping list</p>
<p><a href="https://i.stack.imgur.com/Jvwl2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Jvwl2.png" alt="enter image description here" /></a></p>
<p>But after timeout my <code>tasks</code> array will be replaced by remote fetched data.</p>
<p><a href="https://i.stack.imgur.com/4zUsa.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4zUsa.png" alt="enter image description here" /></a></p>
<p>And as you can see, <code>tasks</code> array lenght is 0 (like <code>console.log()</code> says)</p>
<p>Please, can you exmplain me, why my tasks array is empty if there exists 2 items before 5 seconds.</p>
<p>Of course, I'm adding my tasks to the list normally after hit <code>Enter</code> and <code>handleSubmit</code></p>
<pre class="lang-js prettyprint-override"><code>const handleSubmit = (e) => {
e.preventDefault();
//creating new task
setTasks([
{
id: [...tasks].length === 0 ? 0 : Math.max(...tasks.map((task) => task.id)) + 1,
name: newTask,
isFinished: false,
},
...tasks,
]);
setNewTask('');
}
</code></pre>
<p>Thanks for help or explain. It the problem that <code>useEffect</code> is called after rendering? Of this causing <code>async</code> behavior?</p>

74,172,021 | <p>As an exercise, I wanted to create a useEffect, useState functionality from React.</p>
<p>I achieved similar functionality but I don't like this part of the code:</p>
<pre><code>function Comp() {
let store = new Store();
let [a, setA] = useState(10, store);
let [b, setB] = useState(15, store);
</code></pre>
<p>Basically, each time I create a new "component" I need to create a store. Global store doesn't work because I would need to send additional data when setting new state value
( setValue(value, "KEY") ).</p>
<p>Is there a design pattern or something that I could use to achieve what React does? The only thing that comes to mind is writting sort of a transpiler, but it seems like an overkill and like I am missing something.</p>

<p>EDIT:</p>
<p>The question is how to avoid passing the store to each newly created component.</p>
<p>EDIT 2:</p>
<p>Functionality I want to achieve:</p>
<ol>
<li>I create a "component"</li>
<li>Make use of the useState hook to get [ getter, setter ] =
useState(value)</li>
<li>Each time a setter is called, the useEffect
inside that component should be called, or more precisely it should
check with store if it should be called.</li>
<li>There would be numerous
components, calling setValue(value) from component A should not
trigger a callback effect in component B (why global store doesn't
work, unless i provide additional arguments on a setter to let the
store know which callbacks it should run</li>
</ol>

74,172,026 | <p>I would like to load images dynamically from an images folder.
Names in the folder like <em>{company_name}.png</em>. The names are stored in a <em>json</em> file along with other company data like name, type, etc.</p>
<pre><code>e.g.:
name: meta
logo: "./images/meta.png"
</code></pre>
<p>Is there any way to dynamically load these images like <em>require(<em><strong>changing variable based on the json logo string</strong></em>)</em>.</p>
<hr />
<p>I found some solution online like:
<a href="https://stackoverflow.com/a/52598171/7990652">https://stackoverflow.com/a/52598171/7990652</a></p>
<p>But all the other things are build around the <em>json</em> structure to load all the other data.
Is there any way to load everything from a folder one by one based on the provided logo link in the <em>json</em>?</p>
<hr />
<p>I also tried to look around for a solution with <strong>babilon require all</strong> plugin, but I found nothing about that.</p>
<p><em>P.S. I know there are sevaral threads about this question, but in almost all the threads someone asking "what about if I want to load 100-1000 images?". That is the case with me too, I would like to load a lot of images, not just up to 10-20 which is complately okay with static .js require list.</em></p>

74,172,055 | <p>I have a sidebar with buttons links that targets div id and URL ends with #id_name. Now I want to render data that matches #id_name in a map loop using this code:</p>
<pre><code><div>
{entries.map((item, index) => {
if (asPath.endsWith(`#${item.section}`))
return (
<div id={item.section} key={index}>
<h3>{item.title}</h3>
<p>{item.summary}</p>
</div>
);
})}
</div>
</code></pre>
<p>It works on refresh if #id_name matches item.section but if I click another link nothing happens even if item.section matches #id_name.</p>
<p>How can I re-render the map loop without refreshing or leaving the page when #id_name changes?</p>

74,172,099 | <p>I am trying to use Rx(.net) for a project and I have an issue with how to properly dispose resources that are created during <code>Observable.Create()</code> and emitted with <code>OnNext()</code>. My setup looks like this (shortened to the relevant bits only, hopefully):</p>
<pre><code>var obs = Observable.Create<ReactiveRunData>(async (o) =>
{
if (someCondition)
{
RunData runData = await CreateRunData(); // RunData is IDisposable, needs to be disposed
o.OnNext(runData);
}
o.OnCompleted();
return Disposable.Empty;
})
.Concat(Observable.Empty<RunData>().Delay(TimeSpan.FromSeconds(2)))
.Repeat() // Resubscribe indefinitely after source completes
.Publish().RefCount() // see http://northhorizon.net/2011/sharing-in-rx/
;
</code></pre>
<p>This is my implementation of an observable collection that's infinite and produces an item (of type <code>RunData</code>) every 2 seconds.</p>
<p>Then I do the actual reactive stuff by transforming the IObservable stream using all kinds of operators:</p>
<pre><code>var final = obs
.Select(runData => ...)
// lots of other operations
.Select(tuple => (tuple.runData, tuple.result));`
</code></pre>
<p>The final observable returns a tuple <code>(RunData, Result)</code>.</p>
<p>When subscribing to that observable, at the end I explicitly dispose of the <code>RunData</code> instances, like so:</p>
<pre><code>final.Subscribe(
async (tuple) =>
{
var (runData, result) = tuple;
try
{
// ... do something with result and runData, await some stuff, ...
} catch (Exception e)
{
// error handling
} finally
{
// dispose of runData
runData.Dispose();
}
},
(Exception e) =>
{
// error handling
});
</code></pre>
<p>I suspect this implementation is leaky in various ways, such as when exceptions are thrown from different places, in some cases of which I believe the RunData instance won't get disposed, but is just gone, replaced by an exception travelling through the pipe.</p>
<p>I believe I'd also run into problems if I would add a second subscriber to my observable, right? I don't need more than one subscriber, but that also makes me question my implementation.</p>
<p>I feel like the whole idea of passing data that needs to be disposed by subscribers is wrong, but I couldn't come up with a better way. I tried using <code>Observable.Using()</code>, but afaik that only disposes the resource when the sequence ends, which in my case is never. And I really need an infinite sequence because I want to be able to use functionality like <code>Scan()</code> to reference previous data to build intermediate data structures over time.</p>
<p>I also tried using the callback that is returned from the lambda of <code>Observable.Create()</code> but that fires as soon as Observable.Create() is done and not after the subscriber is done, so that led to race conditions (but I'm not even sure if I understood that correctly, RX + async is tricky).</p>
<p>So... how can I implement this properly?</p>
<p>For some background info, <code>RunData</code> includes (among other things) a DB transaction and an Autofac <code>LifetimeScope</code>, both of which I want to use throughout the pipeline, and both of which need to be disposed at the end, after the subscriber is done.</p>

I want an additional column, that indicates the first score per <code>name</code> / <code>name_ID</code>. The <code>reference_score</code> for the first scores of a name should be NaN. Like this:</p>

also with <code>.nth</code> but it didn't work.</p>

74,172,129 | <p>I have a DataFrame with daily values and I am building out a forecast using various methods predicting the values for the next two weeks.</p>
<p>As a base, naive, forecast I want to simply say the value today is the best forcast for the next two weeks e.g.:</p>
<ul>
<li>the value on <code>01-Jan-2012</code> is <code>100</code>, then I would like the forecast for <code>02-Jan-2012</code> to <code>15-Jan-2022</code> to be <code>100</code></li>
<li>the value on <code>02-Jan-2012</code> is <code>110</code>, then I would like the forecast for <code>03-Jan-2012</code> to <code>16-Jan-2022</code> to be <code>110</code></li>
<li>etc</li>
</ul>
<p>This method can then be compared to the other forecasts to see whether they add value over a naive approach.</p>
<p>To backtest this model how can I do this? I have a few years worth of data in a DataFrame, and I want to do something like below. Reading online, I can only find 1 day persistence help whereby simply using something like <code>df.shift(1)</code> does the job.</p>
<pre><code>Pseudocode:
get the first row from the DataFrame
extract the date from the index
extract the value from the column
propogate forward this value for the next fourteen days
save these forecast dates and forecast values
get the second row from the DataFrame
extract the date from the index
extract the value from the column
propogate forward this value for the next fourteen days
save these forecast dates and forecast values
REPEAT...
</code></pre>
<p>However, I've read that iterating over rows is advised against and it is better to use something like pandas <code>apply</code> to 'vectorize' the data but I am not sure how to do this. I was thinking of writing a function to predict the next 14 days then using the <code>apply</code> method to call this function, but not sure how to do so or if this is the best way.</p>
<p>I've also read that numpy is very good for these sorts of problems, but again, am not too familiar.</p>
<p>I've set up a sqlite database so I can store forecasts in there if that helps.</p>

74,172,197 | <p>I have a Terraform codebase which deploys a private EKS cluster, a bastion host and other AWS services. I have also added a few security groups to the in Terraform. One of the security groups allows inbound traffic from my Home IP to the bastion host so that i can SSH onto that node. This security group is called <code>bastionSG</code>, and that works fine also.</p>
<p>However, initially I am unable to run kubectl from my bastion host, which is the node I use to carry out my kubernetes development on against the EKS cluster nodes. The reason is because my EKS cluster is a private and only allows communication from nodes in the same VPC and i need to add a security group that allows the communication from my bastion host to the <code>cluster control plane</code> which is where my security group bastionSG comes in.</p>
<p>So my routine now is once Terraform deploys everything, I then find the automatic generated EKS security group and add my <code>bastionSG</code> as an inbound rule to it through the AWS Console (UI) as shown in the image below.</p>
<p><a href="https://i.stack.imgur.com/7Dv2d.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7Dv2d.png" alt="enter image description here" /></a></p>
<p>I would like to NOT have to do this through the UI, as i am already using Terraform to deploy my entire infrastructure.</p>
<p>I know i can query an existing security group like this</p>
<pre><code>data "aws_security_group" "selectedSG" {
id = var.security_group_id
}
</code></pre>
<p>In this case, lets say <code>selectedSG</code> is the security group creared by EKS once terraform is completed the apply process. I would like to then add an inbound rule of <code>bastionSG</code> to it without it ovewriting the others it's added automatically.</p>
<p><strong>UPDATE: > EKS NODE GROUP</strong></p>
<pre><code>resource "aws_eks_node_group" "flmd_node_group" {

prepack_qty = serializers.SerializerMethodField()
product_description = serializers.SerializerMethodField()
class Meta:
model = OrderItem
fields = (
"product",
"qty_ordered",
"qty_approved",
"status",
"prepack_qty",
"product_description"
)
def get_prepack_qty(self, obj):
return obj.product.prepack_quantity
def get_product_description(self, obj):
return obj.product.product_description
</code></pre>
<p>When I make a get request to <code>/orders</code>, I make a lot of SQL queries to the database because different orders may contain the same product. How can I cache the result of <code>get_prepack_qty</code> and get_product_description methods? I tried to use <code>@cached_property</code> this way:</p>
<pre class="lang-py prettyprint-override"><code>class OrderItem(models.Model):
...
@cached_property
def item_product_description(self):
return self.product.product_description
</code></pre>
<p>But the number of requests to the database remained the same.</p>

74,172,229 | <p>The React component library should provide a provision to the consuming project to pass configuration file that the component library will use (either during build / runtime)</p>
<p>The configuration file might contain primary, secondary Colors, typography details. (Similiar to how Tailwind has tailwind.config.js)</p>
<p>How do I create this in React JS ?</p>

74,172,274 | <p>I've always been puzzled why I cannot create files in $HOME directory using user_data when using an aws_instance resource. Even a simple "touch a.txt" in user_data would not create the file.</p>
<p>I have worked around this by creating files in other directories (e.g. /etc/some_file.txt) instead. But I am really curious what's the reason behind this & if there is a way to create files in $HOME with user_data.</p>
<p>Thank you.</p>
<p>----- 1st edit -----
Sample code:</p>
<pre><code>resource "aws_instance" "ubuntu" {
ami = var.ubuntu_ami
instance_type = var.ubuntu_instance_type
subnet_id = aws_subnet.ubuntu_subnet.id
associate_public_ip_address = "true"
key_name = var.key_name
vpc_security_group_ids = [aws_security_group.standard_sg.id]
user_data = <<-BOOTSTRAP
#!/bin/bash
touch /etc/1.txt # this file is created in /etc/1.txt
touch 2.txt # 2.txt is not created in $HOME/2.txt
BOOTSTRAP
tags = {
Name = "${var.project}_eks_master_${count.index + 1}"
}
}

<p>Any idea of how we can do that with pandas ?</p>

74,172,509 | <p>I have simple <code>TextField</code> widget that auto expands to a new line if the string width was almost near of max screen width.</p>
<p>Here is the code:</p>
<pre><code> TextEditingController textController = TextEditingController();
TextField(
controller: textController,
textInputAction: TextInputAction.done,
maxLines:null ,
expands: true,
maxLength: 200,
)
</code></pre>
<p><strong>Question</strong>: How can I detect the new line in <code>textController.text</code>?</p>
<p>E.g., we have the following sentence:</p>
<blockquote>
<p>The universe is the greatest mystery known to the<br />
human race</p>
</blockquote>
<p>Notice that between <code>'the'</code> and <code>'human'</code> there is a new line.</p>
<p>I tried to output <code>textController.text</code> but there was nothing found like <code>\n</code> because the new line comes based on <code>UI</code> <code>rendering</code>.</p>
<p>How do I know that in code?</p>

74,172,529 | <p>I've an object showing genres with their counts. It looks like this.</p>
<pre><code>const totalGenresWatchedCount = {
"Comedy": 3,
"Romance": 2,
"Adventure": 1,
"Science Fiction": 1,
"Action": 2,
"Drama": 1,
"Family": 1,
"Crime": 1,
"Thriller": 1

</code></pre>
<p>I also have another array containing all the genres listed.</p>
<pre><code>const totalUniqueGenresWatched = ["Comedy", "Romance", "Adventure", "Science Fiction", "Action"].
</code></pre>
<p>What I want to achieve is get all the genre and the count printed together. Ive tried with the this code.</p>
<pre><code>totalUniqueGenresWatched.map((genre) => {
return (
<p>
{genre} - {totalGenresWatchedCount.genre}
</p>
);
})
</code></pre>
<p>I cant seem to print the object value from the genre key, if I remove the first genre VS Code IntelliSense predicts that the key is not even getting used. Am i missing anything?</p>

74,172,722 | <p>I got a spark data frame (Scala) with many rows, which has a column which is a dictionary (a Json string) of the following format:</p>
<pre><code>[{"ID1":111,"ID2":2,"value":"Z"},
{"ID1":222,"ID2":3,"value":"A"},
{"ID1":333,"ID2":4,"value":"Z"},
{"ID1":444,"ID2":5,"value":"B"},
{"ID1":555,"ID2":6,"value":"Z"},
{"ID1":666,"ID2":7,"value":"Z"},
{"ID1":777,"ID2":8,"value":"A"}]
</code></pre>
<p>I want to filter the dataframe, so it remains only with rows that contains a specific combination, for example ID1 = 111, ID2 = 2, value = Z.
Note: not all rows may have all of the keys, for example, a row might not have the combination
"ID1 = 111".</p>
<p>How can it be done efficiently in Scala spark?
Thanks!</p>

<p>Here is a simple code i wrote:</p>

layout = [[sg.I(key='In'), sg.B('Ok')],[sg.T(enable_events=True,key='T')]]
win=sg.Window("Keyboard Events", layout)
while True:
event, value= win.read()
#close event
if event == sg.WIN_CLOSED:
break
#greeting evnt
if event in ('Ok'): #( 'OK', 'KEYBOARD ENTER EVENT'):
msg = "Hello "+value['In'] # message to show user
win['T'].update(msg) # show user message
win['In'].update("") # clear input field after submitting
win.close()
</code></pre>
<p>What should I say to PySimpleGUI for let it run <code>#greeting event</code> when I press the <code>ENTER</code> key? Can someone help me please? Thanks guys!</p>

74,172,803 | <p>I have a tree with the most frequent letters at the top of the tree and I am trying to find the path to a node so I can turn a message into binary. In this program if I go left, I add 0 to <code>path</code> and, if I go right, I add 1 to the <code>path</code> until I find the node. But I have to go straight to the desired node which is not possible. The only thing I could think of is removing the last character or <code>path</code> if a node has no children, but it does not work if a node has grandchildren. Can someone help me on how to approach this? Thanks!</p>
<pre class="lang-java prettyprint-override"><code> // global variables
String path;
int mark;
// encodes a message to binary
String encoder(char data) {
path = "";
mark = 0;
findPath(root, data);
return path;
}
// finds the path to a node
void findPath(TNode node, char data) {
if(node.data == data) {
mark = 1;
return;
}
if(mark==0 && node.left != null) {
path += 0;
findPath(node.left, data);
}
if(mark==0 && node.right != null) {
path += 1;
findPath(node.right, data);
}
if(mark==0 && node.left == null || node.right == null) {
path = path.substring(0, path.length() - 1);
}
}

<p>In the above table, first column values are given. Now I want to generate 3 values in column 2, 3 and 4 which sum up to value in column 1 for each row. But each of the column 2, 3 and 4 have some predefined data ranges like: column 2 value must lie between 1 and 4, column 3 value must lie between 1 and 3, and, column 4 value must lie between 1 and 3.</p>
<p>I have printed first 8 rows for your understanding. In real case, only "Total" column values will be given and remaining 3 columns will be blank for which values have to be generated.</p>
<p>Any help would be appreciated with the code.</p>

74,172,887 | <p>I am developing image classification models in the Jupyter notebook environment. After getting my model to work with the CPU, I am trying to use the latest TensorFlow Docker image supported for Jupyter & GPU (<a href="https://www.tensorflow.org/install/docker" rel="nofollow noreferrer">tensorflow/tensorflow:latest-gpu-py3-jupyter</a>) so I can take advantage of my GPU for training. The GPU configuration is not the problem (<code>nvidia-smi</code> command shows the GPU is available), but I'm now stuck on what I should do with my image data pipeline setup.</p>
<p>I have folders containing images with the following structure:</p>
<pre><code>my_folder
โ
โโโโTraining
โ โ
โ โโโโClass_A
โ โ 01234.jpg
โ โ 56789.jpg
โ โ ...
โ โ
โ โโโโClass_B
โ โ 01234.jpg
โ โ 56789.jpg
โ โ ...
โ
โโโโValidation
โ โ
โ โโโโClass_A
โ โ 01234.jpg
โ โ 56789.jpg
โ โ ...
โ โ
โ โโโโClass_B
โ โ 01234.jpg
โ โ 56789.jpg
โ โ ...
</code></pre>
<pre><code>path_training = 'my_folder/Training/'
path_validation = 'my_folder/Validation/'
image_size = (90, 90)
</code></pre>
<p>With tensorflow == 2.6.2, I can easily load in my training/validation image datasets with the following code:</p>
<pre><code>train_ds = tf.keras.preprocessing.image_dataset_from_directory(path_training,
seed=1993,
image_size = image_size)
val_ds = tf.keras.preprocessing.image_dataset_from_directory(path_validation,
seed=1993,
image_size = image_size)
</code></pre>
<p>However, it became apparent that this command does not work when using the Docker image:</p>
<blockquote>
<p>----> 3 train_ds = tf.keras.preprocessing.image_dataset_from_directory(path_training,
4 seed=1993,
5 image_size = image_size)</p>
<p>AttributeError: module 'tensorflow_core.keras.preprocessing' has no
attribute 'image_dataset_from_directory'</p>
</blockquote>
<p>So I discovered the tensorflow version of the Docker image is 2.1.0, and that attribute is not listed in the API, which leaves me this option:</p>
<pre><code># Read in all image files and split into training/validation sets (tensorflow-gpu 2.1.0)
train_ds = tf.keras.preprocessing.image.load_img(path_training, target_size = image_size)
val_ds = tf.keras.preprocessing.image.load_img(path_validation, target_size = image_size)
</code></pre>
<p>As might be expected, the <a href="https://www.tensorflow.org/versions/r2.1/api_docs/python/tf/keras/preprocessing/image/load_img" rel="nofollow noreferrer">load_img()</a> command from TensorFlow 2.1.0 does not read in directories, like image_dataset_from_directory() does.</p>
<blockquote>
<p>IsADirectoryError: [Errno 21] Is a directory: 'my_folder/Training/'</p>
</blockquote>
<p>I'm not sure what the best or easiest path forward would be here, as I'm not very familiar with building Docker images. Would it be better to build a Dockerfile based on TensorFlow's latest official tensorflow-GPU & Jupyter Docker image so I can utilize <code>tf.keras.preprocessing.image_dataset_from_directory()</code> or should I just make do with this pre-built Docker image and load my image data with <code>tf.keras.preprocessing.image.load_img()</code> by looping through files in the directory path and creating training/validation image datasets this way? For the latter approach, I searched and found <a href="https://www.programcreek.com/python/example/89223/keras.preprocessing.image.load_img" rel="nofollow noreferrer">some similar examples</a>, notably this example code:</p>
<pre><code>def get_data(dir):
X_train, Y_train = [], []
X_test, Y_test = [], []
subfolders = sorted([file.path for file in os.scandir(dir) if file.is_dir()])
for idx, folder in enumerate(subfolders):
for file in sorted(os.listdir(folder)):
img = load_img(folder+"/"+file, color_mode='grayscale')
img = img_to_array(img).astype('float32')/255
img = img.reshape(img.shape[0], img.shape[1],1)
if idx < 35:
X_train.append(img)
Y_train.append(idx)
else:
X_test.append(img)
Y_test.append(idx-35)
X_train = np.array(X_train)
X_test = np.array(X_test)
Y_train = np.array(Y_train)
Y_test = np.array(Y_test)
return (X_train, Y_train), (X_test, Y_test)

74,172,891 | <p>i have a question that goes with:</p>
<blockquote>
<p>In Java, if we divide two integers, the result is another integer, but the result might not be correct. For example, 4/2 = 2, but 5/2 = 2.5 but in Java the result would be 2 when both 5 and 2 values are stored as integer values. The program should check if the numbers the result of the division is the same when the values are both integers and when they are floats.</p>
</blockquote>
<p>So that I spend over 1 hour to figure this q but i have a problem with the ending part. What it meant in this part: "The program should check if the numbers the result of the division is the same when the values are both integers and when they are floats."</p>
<pre><code>import java.util.Scanner;
class StartUp2{
public static void main(String[] args){
Scanner sc = new Scanner(System.in);
System.out.println("Please type the first number that you want be devided: ");
int a = sc.nextInt();
float b = a;
System.out.println("Please type another number that you want to devide with:");
int c = sc.nextInt();
float d = c;
