C# - What does passing by ref do? : I know what passing by ref is and what it means but what exactly does it do with the objects passed by ref?
Does it guarantee the objects to stay at their current position in memory while the reference is being used?
Does the behavior change between local objects and global objects?
I'm mostly interested with what happens in memory.
**A bit of background information:**
I have written a simple test program that stores the memory address of objects passed by ref and noticed how C# likes to move objects around in memory. But what I think is odd was that the objects being used were locals of a function. This automatically makes me think that the object's reference can't move in memory because it is on the stack. But clearly I'm missing something. What kind of memory was I receiving when using the ref? | 0debug |
Creating game, currently using SQL Server to store data, looking for better alternatives : <p>I have been using SQL Server 2014 to store a DB for the game to use with multiple tables...it's a football game so there are quite a few tables...players, coaches, owners, GMs, scouts, teams, etc...</p>
<p>The question I have is will end users need to have SQL server installed to utilize the DBs in the game? If so, I need to switch to a different option and am wondering what the best option would be for storing large amounts of data which will not require end users to have something special installed to utilize them? </p>
<p>CSV seems the obvious easy answer but I think that would be too much data for a CSV file to handle well.</p>

HTML5 Multiple File Upload. Return lastinsertid through jQuery AJAX and PHP? : <p>I have an html multiple file upload:</p>
<pre><code><input type="file" multiple="multiple">
</code></pre>
<p>I'm successfully uploading files, and writing to my db table:</p>
<p><strong>jQuery</strong></p>
<pre><code>function uploadFile() {
//some other stuff done here...
var ajaxRequest =
$.ajax({
url: '../inc/ajax-upload.php',
type: 'POST',
cache: false,
processData: false, // important
contentType: false, // important
data: formData,
});
ajaxRequest.done(function(data) {
console.log(data);
lastid = 'this comes from data';
$.each(files, function(i, file) {
$('div#files').append('<div class="file-name" id="'+ file['name'] +'">'+file['name']+'<button class="file-delete" id="' + lastid +'">delete</button>');
});
})
ajaxRequest.fail(function(jqXHR) { console.log(jqXHR); })
}
</code></pre>
<p><strong>php</strong></p>
<pre><code>//CRUD stuff in another file
function pdoInsert($sql, $args) {
$pdo = dbConnect();
$stmt = $pdo->prepare($sql);
$stmt->execute($args);
echo $pdo->lastInsertId();
}
function addFile($filename){
$sql = 'INSERT INTO tbl_files (filename) VALUES (?)';
$args = array($filename);
echo pdoInsert($sql, $args);
}
//ajax.php file
$lastid = array();
foreach($_FILES as $file) {
//do filesystem stuff
//insert to db, get last insert id
$lastid[] = addFile($filename);
}
echo json_encode($lastid);
</code></pre>
<p>I want the <code>$lastid</code> from my PHP to be in JSON format like, however, it's returning a concatenated string of the insert id's, e.g. <code>123124[null,null]</code> or something like that. What could be wrong here?</p>

Split up single JSON object into multiple objects : I have a single JSON object that I would like to split up into multiple JSON objects. I'm not sure how to go about splitting up the array with either `filter`, `map` or `reduce`. I couldn't figure out a pattern to break up the single object if there's an absent key, i.e. meal1, meal2, etc. I appreciate any help or pointers in the right direction!
Before
{
"fullName1" : "John Doe",
"attendance1" : 1,
"meal1" : "salmon",
"fullName2" : "Jane Doe",
"attendance2" : 0
}
Desired result
{
"fullName" : "John Doe",
"attendance" : 1,
"meal" : "salmon"
},
{
"fullName" : "Jane Doe"
"attendance" : 0

How to convert DateTime of type DateTimeKind.Unspecified to DateTime.Kind.Utc in C# (.NET) : <p>I've inherited C# code that has an awful lot of DateTimes where the Kind property is DateTimeKind.Unspecified. These are fed into Datetime.ToUniversalTime() which gives back a UTC datetime (it adds 7 hours in my case). This is how ToUniversalTime() works; see MSDN.
The problem is that these DateTimes are in fact already in UTC time. They are pulled out of a SQL Server Compact 4.0 database. They were stored there in UTC. My main question is:</p>
<ol>
<li>How do I modify the Kind property of a DateTime so that it's UTC and not Unspecified? I don't want to change the time or date. So for example, a date of April 1st 2013, 9:05 am with its Kind property of "Unspecified" should become a datetime of April 1st 2013, 9:05 UTC. </li>
</ol>
<p>If I could be indulged with a follow up question(s), it would be:</p>
<ol start="2">
<li>Are values necessarily returned from Sql Server Compact as "Unspecified"? Inside Sql Server Compact, they are being stored as type (datetime, not null). Looking at the code, it appears they are just put in the database, but there are no provisions to mark them as UTC or anything. Is there a better way to handle things? Is there a slick way to ensure the DateTimes come out of SQL Compact as UTC?</li>
</ol>
<p>Please let me know if I can provide more details. I'm new to this code base and still getting my brain around it, so I'm having trouble describing the problem perfectly.</p>

C++: Accessing specific value from single key-multiple value containers : So, it happens that I'm working on the task. So I was trying to implement a multi-value containers using C++ and to freely access each of the values inside. I have int key; values like X, Y, Width, Height as input.
I was trying to extract the values from each key.
But obviously, the code doesn't work in this case.
Would like some advice whether this can be done or any predefined container libraries with better flexibility in terms of accessing multiple values.
tried with independent single-key, single-value 'multimap' containers, but it consume too much memory space and drag performance
multimap<int, multimap <multimap<int, int>, multimap<int, int>>> BlobPos = {};
//[<1,{(2,3),(4,5)}>,<2,{(6,7),(8,9)}>
for (auto it = BlobPos.begin();it != BlobPos.end(); it++) {
auto X = it->second-> first->first;
auto Y = it->second->first->second;
auto H = it->second->second->first;
auto W = it->second-second->second;
cout << X << Y << H << W;

Python with...as for custom context manager : <p>I wrote a simple context manager in Python for handling unit tests (and to try to learn context managers):</p>
<pre><code>class TestContext(object):
test_count=1
def __init__(self):
self.test_number = TestContext.test_count
TestContext.test_count += 1
def __enter__(self):
pass
def __exit__(self, exc_type, exc_value, exc_traceback):
if exc_value == None:
print 'Test %d passed' %self.test_number
else:
print 'Test %d failed: %s' %(self.test_number, exc_value)
return True
</code></pre>
<p>If I write a test as follows, everything works okay.</p>
<pre><code>test = TestContext()
with test:
print 'running test %d....' %test.test_number
raise Exception('this test failed')
</code></pre>
<p>However, if I try to use with...as, I don't get a reference to the TestContext() object. Running this:</p>
<pre><code>with TestContext() as t:
print t.test_number
</code></pre>
<p>Raises the exception <code>'NoneType' object has no attribute 'test_number'</code>.</p>
<p>Where am I going wrong?</p>

C vs C++ compilation incompatibility - does not name a type : <p>I am trying to use a supplier's library in combination with my C++ application. The library is largely based on C, which is normally not a problem with the <code>extern "C"</code> option, but I ran into an issue that the C++ compiler does not accept. </p>
<p>I simplified my code into the following example files. header.h represents a header from the suppier library, main.c/cpp are my own files. My real application is a C++ application, so I want to get it to work with main.cpp. </p>
<p>header.h (note the line <code>u64 u64;</code>):</p>
<pre><code>#ifndef HEADER_H
#define HEADER_H
#include <stdint.h>
typedef uint64_t u64;
union teststruct {
u64 u64;
struct {
u64 x:32;
u64 y:32;
} s;
};
#endif
</code></pre>
<p>main.c:</p>
<pre><code>#include <stdio.h>
#include "header.h"
int main() {
union teststruct a;
a.u64=5;
printf("%x\n", a.u64);
return 0;
}
</code></pre>
<p>main.cpp (same as main.c but with an extra <code>extern "C"</code> statement): </p>
<pre><code>#include <stdio.h>
extern "C" {
#include "header.h"
}
int main() {
union teststruct a;
a.u64=5;
printf("%x\n", a.u64);
return 0;
}
</code></pre>
<p>Compiling main.c using the line</p>
<pre><code>gcc -o test main.c
</code></pre>
<p>compiles without problems. However, compiling the C++ version using the g++ compiler with the command </p>
<pre><code>g++ -o test main.cpp
</code></pre>
<p>gives the following compiler errors:</p>
<pre><code>In file included from main.cpp:12:0:
header.h:11:9: error: ‘u64’ does not name a type
u64 x:32;
^
header.h:12:9: error: ‘u64’ does not name a type
u64 y:32;
^
</code></pre>
<p>The issue is that the supplier used the same name (u64) for both the type and the variable name, which seems like a bad idea to begin with, but gcc apparently accepts it. I do not want to change the library (i.e. header.h) as it is very large,this occurs a lot in the code, and I occasionally get updates for it. Is there a way to make g++ accept this combination, or a way to modify main.cpp to make it compile <em>without</em> changing header.h?</p>

<p>If I let the dot, like in <code><location path=".well-known/acme-challenge"></location></code>, the site doesn't start at all (I think the web.config file is not parsed at all because I get the page asking me to configure customErrors, but it is already configured and usually works fine)</p>
<p>If I remove the dot, like in <code><location path="well-known/acme-challenge"></location></code> the web.config file is correctly loaded, but of course that doesn't help me to configure anything at the location I wish.</p>
<p>The final goal is to disable basic authentication (which I need for the rest of the site) on this path only ; I don't even know if I'll be able to set this up in a <code><location></code> element.</p>

<p>Now I have 2 issues that stop my work.
1) I cannot use <code>conda install</code> for any package.
It will give me the error in <code>solving environment</code> list this:</p>
<pre><code>failed with initial frozen solve. Retrying with flexible solve.
</code></pre>
<p>then it will fail again and give message like this:</p>
<pre><code>Found conflicts! Looking for incompatible packages.
This can take several minutes. Press CTRL-C to abort.
</code></pre>
<p>Even after the checking for incompatible packages, it didn't give me the solution.</p>
<p>2) When I want to upgrade or downgrade conda by the command:</p>
<pre><code>conda update -n base conda
</code></pre>
<p>or</p>
<pre><code>conda install conda = 4.6.11
</code></pre>
<p>It will give me errors again in the <code>solving environment</code>, and I think this is related to the first issue.</p>
<p>Now I cannot use conda for anything, please advise and thank you!</p>

There must be and easier way? The element has a class but there are more identical elements I also need to adjust individually.

Update console without flickering - c++ : <p>I'm attempting to make a console side scrolling shooter, I know this isn't the ideal medium for it but I set myself a bit of a challenge.</p>
<p>The problem is that whenever it updates the frame, the entire console is flickering. Is there any way to get around this?</p>
<p>I have used an array to hold all of the necessary characters to be output, here is my <code>updateFrame</code> function. Yes, I know <code>system("cls")</code> is lazy, but unless that's the cause of problem I'm not fussed for this purpose. </p>
<pre><code>void updateFrame()
{
system("cls");
updateBattleField();

Google Cloud Functions to only Ack Pub/Sub on success : <p>We are using a cloud function triggered by Pub/Sub to ensure delivery of an e-mail. Sometimes the e-mail service takes a long time to respond and our cloud function terminates before we get an error back. Since the message has already been acknowledged our e-mail gets lost.</p>
<p>The cloud function appears to be sending an ACK the Pub/Sub message automatically when we are called. Is there a way to delay the ACK until the successful completion of our code? Alternatively is there a way to catch timeouts and requeue the message for delivery? Something else we could try? </p>

How to avoid using allow_any_instance_of? : <p>Imagine we have following piece of code:</p>
<pre><code>class A
def create_server
options = {
name: NameBuilder.new.build_name
}
do_some_operations(options)
end
end
</code></pre>
<p>To test such methods, I've used to use <code>allow_any_instance_of</code>:</p>
<pre><code>it 'does operations' do
allow_any_instance_of(NameBuilder).to receive(:build_name)
# test body
end
</code></pre>
<p>But docs advise us not to use it <a href="https://relishapp.com/rspec/rspec-mocks/docs/working-with-legacy-code/any-instance" rel="noreferrer">because of several reasons</a>. How then avoid <code>allow_any_instance_of</code>? I've came to only one solution: </p>
<pre><code>class A
def create_server
options = {
name: builder.build_name
}
do_some_operations
end
private
def builder
NameBuilder.new
end
end
</code></pre>
<p>But with such approach code quickly becomes full of almost useless methods (especially when you actively using composition of different objects in described class).</p>

Using webkitdirectory to upload a directory, is it possible to filter out certain files prior to uploading? : <p>I'm using <a href="https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement/webkitdirectory" rel="noreferrer">webkitdirectory</a> to create an input that allows uploading an entire folder (rather than selecting individual files). I know it's non-standard and shouldn't be used in production.</p>
<p>I'm uploading a specific type of folder where there is one very large file that isn't needed, and many other small files. The upload takes a long time because there's a large file, but because coincidentally that's also the one file I don't actually need on the server side, I'm wondering if there's any way to filter it out prior to being uploaded?</p>

Making sinusoidal curve in image into straight line in output image Matlab : I have to make a sinusoidal curve in image to Output an equal straight line in the resulting image. [an example of input sinusoidal image is here][1].
What i think is one solution should be,
Placing down the origin of x and y coordinates at the start of the curve, so we will have y=0 at starting point.
then points on the upper limit will be counted as such that
y= y-(delta_y)
and for lower limits,
y=y+(delta_y)
so to make upper points a straight line, our resulting image will be
O[x,y-delta_y]= I[x,y];
but how to calculate deltaY for each y on horizontal x axis(it is showing distance of curve points from horizontal axis)
Another solution could be, to save all information of the curve in a variable and to plot it as a straight line, but how to do it?

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.
If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.
If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.
If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.

android: button click error (string array) : When I select an item with a spinner and click the button, I want to create a program that generates an array of choices with the spinner, such as 5 to add random numbers and float them in a textview. There are no errors, but when running, click the button to exit the program. Which part is the problem? The entire code is as follows:

String num=s.getSelectedItem().toString();
numnum = Integer.parseInt(num);
}
public void onNothingSelected(AdapterView<?> parent) {
}
});
button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
int array1[] = null;
String string1[];
for (int i = 0; i<numnum; i++){
array1[i]=((int)(Math.random()));
text1.setText("num #"+(i+1)+": "+array1[i]+"/n");

I'm trying to show the value of "string01" in a wxMessageBox (as seen in "inheritedgui.cpp"), however when I click "m_button2", nothing happens and I don't know why :/
https://i.postimg.cc/jd6WDc6z/Screenshot-20200227-040106.png
What changes do I need to do so the wxMessageBox shows up when I click "m_button2" (is the one which says "List")?
Thanks!

Apply a function to all the elements of a data frame : <p>I am trying to apply some transformations to all the elements in a dataframe.</p>
<p>When using the regular apply functions, I get a matrix back and not a dataframe. Is there a way to get a dataframe directly without adding <code>as.data.frame</code> to each line?</p>
<pre><code>df = data.frame(a = LETTERS[1:5], b = LETTERS[6:10])
apply(df, 1, tolower) #Matrix
apply(df, 2, tolower) #Matrix
sapply(df, tolower) #Matrix
as.data.frame(sapply(df, tolower)) # Can I avoid "as.data.frame"?

fasted way to read file in python : I made a python script to analyze logs. I have one observation to share, and two questions to ask.
When I use gzip.open to open each file and go through every line, it takes around 200 seconds just to going through all the lines and files.
with gzip.open(file) as fp:
for line in fp:
If using `zcat` and `grep` to do the work, it takes about 50 seconds.
temp = commands.getstatusoutput("zcat file* | grep pattern")
The performance difference is too huge to ignore. Is there a better way to reduce the gap?
I also noticed that the `commands` module is made obsolete by the `subprocess` module, which seems always create a temporary file. But it wouldn't be convenient, what if it is not possible to create a temporary file from where the python script is running? Any suggestion?

object to string in Python : <p>I have some data objects on which I want to implement a to string and equals functions that go in depth. </p>
<p>I implemented <strong>str</strong> and <strong>eq</strong> and although equality works fine I cannot make <strong>str</strong> behave in the same way:</p>
<pre><code>class Bean(object):
def __init__(self, attr1, attr2):
self.attr1 = attr1
self.attr2 = attr2
def __str__(self):
return str(self.__dict__)
def __eq__(self, other):
return self.__dict__ == other.__dict__
</code></pre>
<p>When I run:</p>
<pre><code>t1 = Bean("bean 1", [Bean("bean 1.1", "same"), Bean("bean 1.2", 42)])
t2 = Bean("bean 1", [Bean("bean 1.1", "same"), Bean("bean 1.2", 42)])
t3 = Bean("bean 1", [Bean("bean 1.1", "different"), Bean("bean 1.2", 42)])
print(t1)
print(t2)
print(t3)
print(t1 == t2)
print(t1 == t3)
</code></pre>
<p>I get:</p>
<pre><code>{'attr2': [<__main__.Bean object at 0x7fc092030f28>, <__main__.Bean object at 0x7fc092030f60>], 'attr1': 'bean 1'}
{'attr2': [<__main__.Bean object at 0x7fc091faa588>, <__main__.Bean object at 0x7fc092045128>], 'attr1': 'bean 1'}
{'attr2': [<__main__.Bean object at 0x7fc0920355c0>, <__main__.Bean object at 0x7fc092035668>], 'attr1': 'bean 1'}
True
False
</code></pre>
<p>since t1 and t2 contain the same values the equals return true (as expected) while since t3 contains a different value in the list the result is false (also as expected).
What I would like is to have the same behavior for the to string (basically to also go in depth also for the elements in list (or set or dict ...).</p>
<p>For print(t1) I would like to obtain something like:</p>
<pre><code>{'attr2': ["{'attr2': 'same', 'attr1': 'bean 1.1'}", "{'attr2': 42, 'attr1': 'bean 1.2'}"], 'attr1': 'bean 1'}
</code></pre>
<p>which is actually obtained if I do:</p>
<pre><code>Bean("bean 1", [Bean("bean 1.1", "same").__str__(), Bean("bean 1.2", 42).__str__()]).__str__
</code></pre>
<p>Since I do not know the types of the attributes attr1, attr2 in my Bean objects (they may be lists but also sets, dictionaries etc.) is would be nice to have a simple and elegant solution that would not require type checking ...</p>
<p>Is this possible ?</p>

Why utilize using() when instantiating a class? : <p>I have been working with C# ASP.NET MVC5 for a while and I was wondering something.
Why are we utilizing the using() to instantiate a class sometimes?</p>

<pre><code>using (CyrptoStream cs = new CryptoStream(PARAMETERS)
{
//SOMETHING
}
</code></pre>
<p>or</p>
<pre><code>using (Aes encryptor = Aes.Create()
{
}
</code></pre>
<p>How is that different to <code>MyClass myClass = new MyClass()</code></p>

Can you pattern match a non empty array in elixir? : <p>I have a <code>User</code> model with a <code>has_many</code> relationship to <code>other_model</code>.
I have a function <code>Search</code> that searches the internet. What I would like to do is search the internet only if the <code>has_many</code> relationship is not an empty array. </p>
<p>So I'm wondering if I can pattern match against a non-empty array? As you can see below, the extra <code>Search</code> results in nested branch and hence I use the <code>with</code> statement and am hoping for a clean solution. </p>
<pre><code>query = from a in Model, where: a.id == ^id, preload: [:some_associations]
