how to make a pause in c# form? : hi every one i'm trying to write a recursion program (tower of hanoi) and each step must shown in windows form one by one with a little delay but sleep and task.delay didn't work for me :(
here's my code:
public void solve(int a,int b,int c,int n,PictureBox[] arr)
{
if (n == 1)
{
h[c].Push(h[a].Pop());
print(arr);
return;
}
solve(a, c, b, n - 1,arr);
h[c].Push(h[a].Pop());
solve(b, a, c, n - 1, arr);
print(arr);
// System.Threading.Thread.Sleep();
}

Fill a complex Java Object with dummy values : <p>If A, B, C, D are classes. Suppose a class A is structured as below.</p>
<pre><code> class A{
private List<B> bList;
private String name;
private boolean dude;
private C c;
private D d;
//Getter and Setter Methods
}
</code></pre>
<p>B , C and D have some properties like String, boolean etc. say</p>
<pre><code>class B{
private String e;
private boolean b;
.....
//Getter and Setter Methods
}
</code></pre>
<p>Now I want to create an object of A with its property B, C and D not being null but filled with Dummy values say <code>"abc"</code> for <code>String</code>, <code>1</code> for <code>int</code> , <code>false</code> for <code>boolean</code>.</p>
<p>So the aim is to create an object <code>A</code> with dummy values. How can this be achieved ?</p>

Visualize DynamoDB data in AWS Quicksight : <p>I am looking for an AWS-centric solution (avoiding 3rd party stuff if possible) for visualizing data that is in a very simple DynamoDB table.</p>
<p>We use AWS Quicksight for many other reports and dashboards for our clients so that is goal to have visualizations made available there. </p>
<p>I was very surprised to see that DynamoDB was not a supported source for Quicksight although many other things are like S3, Athena, Redshift, RDS, etc.</p>
<p>Does anyone have any experience for creating a solution for this?</p>
<p>I am thinking that I will just create a job that will dump the DynamoDB table to S3 every so often and then use the S3 or Athena integrations with Quicksight to read/display it. It would be nice to have a simple solution for more live data.</p>

How to handle kafka publishing failure in robust way : <p>I'm using Kafka and we have a use case to build a fault tolerant system where not even a single message should be missed. So here's the problem:
If publishing to Kafka fails due to any reason (ZooKeeper down, Kafka broker down etc) how can we robustly handle those messages and replay them once things are back up again. Again as I say we cannot afford even a single message failure.
Another use case is we also need to know at any given point in time how many messages were failed to publish to Kafka due to any reason i.e. something like counter functionality and now those messages needs to be re-published again.</p>
<p>One of the solution is to push those messages to some database (like Cassandra where writes are very fast but we also need counter functionality and I guess Cassandra counter functionality is not that great and we don't want to use that.) which can handle that kind of load and also provide us with the counter facility which is very accurate.</p>
<p>This question is more from architecture perspective and then which technology to use to make that happen.</p>
<p>PS: We handle some where like 3000TPS. So when system start failing those failed messages can grow very fast in very short time. We're using java based frameworks.</p>
<p>Thanks for your help!</p>

Applying Format to Entire Row Openpyxl : <p>I have an Excel File that I want to format. The first row (excluding Headers so row2) should be red and <em>italicized</em>.</p>
<p>the <a href="http://openpyxl.readthedocs.io/en/2.3.3/styles.html" rel="noreferrer">Openpyxl Documentation states</a>: </p>
<blockquote>
<p>If you want to apply styles to entire rows and columns then you must apply the style to each cell yourself</p>
</blockquote>
<p>I personally thinks this stinks... Here is my workaround:</p>
<pre><code>import openpyxl
from openpyxl.styles import NamedStyle
from openpyxl import load_workbook
from openpyxl.styles.colors import RED
from openpyxl.styles import Font
# I normally import a lot of stuff... I'll also take suggestions here.
file = 'MY_PATH'
wb = load_workbook(filename=file)
sheet = wb.get_sheet_by_name('Output')
for row in sheet.iter_rows():
for cell in row:
if '2' in cell.coordinate:
# using str() on cell.coordinate to use it in sheet['Cell_here']
sheet[str(cell.coordinate)].font = Font(color='00FF0000', italic=True)
wb.save(filename=file)
</code></pre>
<p>The first downside is that if there are more cells such as <code>A24</code> my loop will apply the formatting to it. I can fix this with a regular expression. Would that be the correct approach?</p>
<p><strong>Ultimately- is there a better way to apply a format to the entire row?</strong> Also. Can anyone point me in the right direction to some <em>good</em> Openpyxl documentation? I only found out about <code>sheet.iter_rows()</code> and <code>cell.coordinates</code> on Stack.</p>

I want to be able to shorten code in python, how can I do that? : <p>I am making a discord bot in python with discord.py. I want to know how i can shorten this function to fewer lines. This function takes a command (-cf red, for example) and flips a coin with both a red side and a blue side. When the results are in the code sends a DM to the person doing the coinflip while at the same time sending the results in the chat.</p>
<pre><code>@bot.command(aliases=['coinflip'])
async def cf(ctx, *, cfchoice):
cfResults = random.choice(['red','blue'])
userId = ctx.message.author.id
user = bot.get_user(userId)
time.sleep(1)
# If the user wins the coinflip
if cfchoice == cfResults:
# Send result in the channel
await ctx.send(f'It is {cfResults}!')
# Send a DM to the person
await user.send('You won on coinflip! Well done.')
# If the user loses the coinflip
elif cfchoice != cfResults:
# Send result in the channel
await ctx.send(f'It is {cfResults}!')
# Send a DM to the person
await user.send('You lost on coinflip! Good luck next time.')

Angular 2 prevent enter from submitting in template-driven form : <p>I have forms that uses the template-driven blueprint, so something like this:</p>
<pre><code><form #myForm="ngForm" ngSubmit="save(myForm.value, myForm.isValid)">
<input #name="ngModel" [(ngModel)]="name">
<button type="submit">Submit form</button>
</form>
</code></pre>
<p>Now, how can I prevent ENTER from submitting the form? It interferes with custom ENTER behaviour inside of the form and also if you accidentally press enter in an input, which is unwanted.</p>
<p>I've looked around and found some old Angular 1 answers and also some standard JavaScript ones but I feel that Angular 2 must have something like this already built in but I haven't been able to find it.</p>
<p>If they don't, what would be the best way to achieve this?</p>

comparison in forloop : i am fairly new to java and came across a problem while working on a project where i need to extract some data by comparing each result that i get out of a forloop with the other.
The forloop is to get results out of an sql query & the code for the forloop is as following:
for (Map<String, Object> row : results) {
String data= row.get("getdata").toString();
}
The data recieved out of this when the loop runs 2 times is somewhat like:
a12:1:123;b23:2:234;c24:3:344
a12:1:123;b23:2:234;c24:4:345
when, in the above data for the same first vale, the second value after ":" is different, i want to get the third value, for example between c24:3:344 & c24:4:345 the second value is different i.e. 3 and 4 so i need to get 344 and 345.
similarly i need to find any such data in the results received by the for loop.
All you help is greatly appreciated and thanks in advance.

Can't remove space on top of nav_host_fragment : <p>I just implemented a bottom navigation (AS's default - File -> New -> Activity -> Bottom Navigation Activity) Everything is fine except for a space on the top of the <code>nav_host_fragment</code>. </p>
<p><img src="https://i.ibb.co/vwYBJPG/space.png" alt="wrong space"></p>
<p>Since it was generated in a ConstraintLayout, I tried to clean the constraints and set the top constraint with <code>parent</code>, setting <code>margin</code> to '0dp' and set <code>height</code> to <code>match_constraint</code>.</p>
<p>I unsuccessfully deleted the constraints and tried over and over again.</p>
<p>I used <code>Clean Project</code>.</p>
<p>I changed to RelativeLayout and set arguments like this:</p>
<pre><code> <fragment
android:id="@+id/nav_host_fragment"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_above="@+id/nav_view"
app:defaultNavHost="true"
app:navGraph="@navigation/mobile_navigation" />
</code></pre>
<p>But the space between <code>nav_host_fragment</code> and the top is still there.</p>
<p>Here's the lyout file:</p>
<pre><code><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"

TypeScript TS7015: Element implicitly has an 'any' type because index expression is not of type 'number' : <p>Im getting this compilation error in my Angular 2 app:</p>
<pre><code>TS7015: Element implicitly has an 'any' type because index expression is not of type 'number'.
</code></pre>
<p>The piece of code causing it is:</p>
<pre><code>getApplicationCount(state:string) {
return this.applicationsByState[state] ? this.applicationsByState[state].length : 0;
}
</code></pre>
<p>This however doesn't cause this error:</p>
<pre><code>getApplicationCount(state:string) {
return this.applicationsByState[<any>state] ? this.applicationsByState[<any>state].length : 0;
}
</code></pre>
<p>This doesn't make any sense to me. I would like to solve it when defining the attributes the first time. At the moment I'm writing:</p>
<pre><code>private applicationsByState: Array<any> = [];
</code></pre>
<p>But someone mentioned that the problem is trying to use a string type as index in an array and that I should use a map. But I'm not sure how to do that.</p>
<p>Thans for your help!</p>

Having trouble writing a main method for my class : <p>So im writing a method for my computer science class in which im trying to make a kinda like walking path thing. What i want to do is test the methods where the isLevelSegment part will return true if the difference between the maximum and minimum elevation in the walking path segment is less than or equal to ten meters and the isDifficult method is trying to see if there are 3 or more elevation changes in a path ( elevation changes are at least 30 meters up or down ). All my code is written [ idk if its correct or not, i think it is ] and basically and idk why im having a really hard time writing the main method to test it. Help?</p>
<p>public class Lab11 {</p>
<pre><code>public class WalkingPath
{
private int[] markers;
public boolean isLevelSegment (int start, int end )
{
int min = 1;
int max = 0;
for (int i = start; i<= end ; i ++)
{
if (markers[i] > max)
max = markers[i];
if (markers[i] < min || min == -1)
min = markers [i];
}
if ((max - min) <= 10)
return true;
else
return false;
}
public boolean isDifficult ()
{
int changes = 0;
for ( int i = 1 ; i< markers.length ; i ++)
{
if ((markers[i] - markers [i - 1]) >= 30)
changes ++;
}
if (changes >= 3)
return true;
else
return false;

Find Highest Value in a dictionary : <p>I have a dictionary like so:</p>
<pre><code>class1 = {
max: 10, 3, 5
Michael: 4. 4, 8
jack: 0, 0, 3
}
</code></pre>
<p>This is the relevant code</p>
<pre><code>class1 = {}
with open("1.txt", "r+") as f:
for line in f:
columns = line.split(":")
if len(columns) == 2:
names = columns[0]
scores = columns[1].strip()
else:
pass
if class1.get(names):
class1[names].append(scores)
else:
class1[names] = list(scores)
</code></pre>
<p>The numbers represent the scores and I would like for the highest score for each name to be printed out, this is my desired output:</p>
<pre><code>max: 10
Micheal: 8
jack: 3
</code></pre>
<p>I have already tried this:</p>
<pre><code>max_value = max(class1.values())
print(sorted(max_value))
</code></pre>
<p>But it makes no difference to my output.</p>

<p>Question: how to achieve this effect? I mean what kind of manifest declaration or programmatic call (possibly Samsung's legacy API) should I use?</p>

jQuery $(this).data() is returning old values : <p>I have the following code:</p>
<pre><code>updateColors = function() {
$(".color-preview").each(function() {
return $(this).css('background-color', $(this).data('color'));

</code></pre>
<p>I put a breakpoint on the 3rd line, and type the following into the console:</p>
<pre><code>> this
<div class="color-preview" data-observer="{"attr":"data-color", "observe":"btn_col"}" data-color="#ffff00" style="background-color: rgb(153, 0, 255);"></div>
> $(this).data('color')
"#9900ff"
</code></pre>
<p>As you can see, the actual element's <code>data-color</code> is <code>#ffff00</code>. However, jQuery's <code>.data()</code> method is returning <code>#9900ff</code>, which <em>was</em> the value of the element's <code>data-color</code>, but has been changed (and using the breakpoint, I can see that yes it has already changed).</p>

R dplyr - count and select first row by group : df <- data.frame(id = c(1, 1, 2, 2, 2), desc = c("a1", "a2", "b1", "b2", "b3"))
I would like to count by id and select the first row of desc within each id group. That is, return a data frame like the following.
```
id count desc
1 2 a1
2 3 b1
```
Is there an easy way to do it using dplyr package? Can pipes + group_by() + summarise() do the work without using filter() and join()?
Stata can do it as
`collapse (count) count=id (first) desc, by(id)`
Thanks.

Best practice for nodejs deployment - Directly moving node_modules to server or run npm install command : <p>What is the best practice for deploying a nodejs application?</p>
<p>1) Directly moving the node_modules folders from the development server to production server, so that our same local environment can be created in the production also. Whatever changes made to any of the node modules remotely will not affect our code.</p>
<p>2) Run <code>npm install</code> command in the production server with the help of package.json. Here the problem is, any changes in the node modules will affect our code. I have faced some issues with the loopback module (<a href="https://stackoverflow.com/questions/50683224/loopback-getting-error-major-change-in-user-validatepassword-function-in-the-s">issue link</a>). </p>
<p>Can anyone help me?</p>

how to do code listing in Latex without line numbers (when using lstlisting environment) : <p>I have been writing a project report and have added some pseudo codes using the following command : lstlisting in Latex as shown bellow.</p>

# On leave focus of email field
IF email is blank
Error message: "Please enter an email address"
ELSE IF email field value is not a valid email address
Error message: "Wrong email please try again"}
# On leave focus of password
IF password is not sufficiently strong
Error message: "Password strength is not good"
\end{lstlisting}
</code></pre>
<p>The above works just fine but in the code block thy are some line numbers appearing and I would like to get ride of those. Any hints on how to remove them?
I also know the following:</p>
<pre><code> \section*{New section}
</code></pre>
<p>Would give a section title without number. But in the case of code listing it doesn't work and produce an error instead.</p>

https on S3 WITHOUT cloudfront possible? : <p>We currently want to start hosting all our assets through AWS S3 and we also want to server everything over https. I understand I can use the Amazon Certificate Manager (ACM) with Cloudfront to server assets over https. The problem is that we are in the medical industry and we are legally prohibited to host anything outside the EU. With S3 I can choose a location (Frankfurt for us), but with Cloudfront I just get this option:</p>
<p><a href="https://i.stack.imgur.com/PYiFr.png" rel="noreferrer"><img src="https://i.stack.imgur.com/PYiFr.png" alt="enter image description here"></a></p>
<p>So I thought that I could maybe use Letsencrypt to generate my own certs. But I think I then still need to use ACM which only works with Cloudfront, which means I still can't use it.</p>
<p>Does anybody know if I can somehow setup S3 with https but <em>without</em> cloudfront?</p>

500 Internal Server Error in wordpress. Tried everithing : I've got a pretty old and large wordpress website to fix and develop it. After I fixed some error, **I got an "Internal Server Error 500" globally to that subdomain** (also for wp-admin,wp-login,index.php,etc...).
-Firstly I **checked for the .htaccess file**, deleted it, manually recreated it with the wordpress defaults, but it didn't help.
Secondly I incrased the php limit with added a php.ini file, and also defined the limit in wp-config.php, but nothing changed.
-Then I **deactivated all plugins** (renamed the plugin directory), but still nothing.
-I **updated the "wp-admin", "wp-includes" directories, and some other core files** from a newly installed worpress.
-I realized that the directories and files premissions are wrong. I **set the 644 (for files) and 755 (for directories) premissions.** Still got the error.
-I **modified the "home" and "site url" options** in phpmyadmin to the subdomain.
-After that I decided to reinstall the whole wordpress to fix the problem, and I started to downloading the wp-content to my computer (25 GB) when I found some .php files in the uploads and in the gallery. They were mostly some kind of backdoors...fortunately apache weren't running on my machine. Finished with the download after 15 hours. I was very happy.
-After all, I created an additional backup directory on the FTP server and moved the old wp site into that. I **uploaded the newest wordpress to the original site location on the server, and set the wp-config.php file. But I sill got the "500 Internal Server Error"...**
**In conclusion, I guess the problem is in the mysql database, but I hope I'm wrong. It's pretty large and no idea what could be the issue in that. Perhabs something in the wp_options table. I don't know.**
I use WinSCP for FTP connect, Notepad++ and Eclipse for editing.
If you had patience to read that, **please help me with some useful idea**.
Thanks!

Why are numpy functions so slow on pandas series / dataframes? : <p>Consider a small MWE, taken from <a href="https://stackoverflow.com/q/47881048/4909087">another question</a>:</p>
<pre><code>DateTime Data

2017-11-28 14:59:48 1
</code></pre>
<p>The goal is to clip all values with an upper bound of 1. My answer uses <code>np.clip</code>, which works fine.</p>
<pre><code>np.clip(df.Data, a_min=None, a_max=1)
array([1, 1, 1, 1, 1, 1, 0, 1])
</code></pre>
<p>Or, </p>
<pre><code>np.clip(df.Data.values, a_min=None, a_max=1)
array([1, 1, 1, 1, 1, 1, 0, 1])
</code></pre>
<p>Both of which return the same answer. My question is about the relative performance of these two methods. Consider - </p>
<pre><code>df = pd.concat([df]*1000).reset_index(drop=True)
%timeit np.clip(df.Data, a_min=None, a_max=1)
1000 loops, best of 3: 270 µs per loop
%timeit np.clip(df.Data.values, a_min=None, a_max=1)
10000 loops, best of 3: 23.4 µs per loop
</code></pre>
<p>Why is there such a massive difference between the two, just by calling <code>values</code> on the latter? In other words...</p>

Is Google Cloud Storage an automagical global CDN? : <p>I’m attempting to setup a Google Cloud Storage bucket to store and serve all the static objects for my site. I’m also attempting to push all the objects in that bucket out to all the global edge locations offered by Google Cloud CDN.</p>
<p>I’ve created a bucket on Google Cloud Storage: <code>cdn.mysite.com</code>. I chose “US” multi-region for the bucket <code>location</code> setting.</p>
<p>My assumption is that any object stored in this bucket will be replicated to all the <code>us-*</code> regions for high-durability purposes, but <strong>not</strong> pushed out to all the Google Cloud CDN global edge locations for CDN purposes.</p>
<p>Or are all my objects in my “US” multi-region bucket already automagically pushed out to all of Google Cloud CDN edge locations?</p>
<p>I’m gobsmacked that I can’t figure out whether or not my bucket is <em>already</em> a CDN or not. Even after two days of searching (Google, ironically).</p>
