Passing an optimization flag to a Go compiler? : <p>To compile a Go program you type <code>go build myprogram.go</code>, can you pass an optimization flags along or the code is always compiled in the same way? I am talking about speed optimizations, code size optimizations or other optimizations.</p>
<p>I know if you use <code>gccgo</code> you just pass <code>-O2</code> or <code>-O0</code> but my question is about an official Go compiler <code>go</code>.</p>

Flutter - Overlay card widget on a container : <p>In flutter, is it possible to place a part of a card on another container. In CSS, we would set margin top to a negative value or use translate property. In flutter as we cannot set negative values to margin top, is there an alternative to that?</p>

How to deal with very long arrays : <p>I have a <code>longArray</code> which contains other long <code>arrays</code> at the beginning of my code(think of it as a database). I'm afraid if it slows down the speed of my code. </p>

What are keys used for in Flutter framework? : <p>Flutter is an amazing framework straightforward and easy to use. I must see that the documentation is very good but there are some concept that are still vague to me, for instance the <code>key</code> parameter. According to the documentation <code>A Key is an identifier for Widgets, Elements and SemanticsNodes.</code> It's clear, but why do I need to identify my widgets. So far I never used keys in my coding. Is there any benefits of using keys in my code? Thanks.</p>

I want to group by t_id and find the sum of val1 according to each t_id and divide the val1 by total number of t_id .... eg: there are three t-id 1 in the array and sum is of three t_id is 3(val1)..so the val1 must be 3/total t_id( ie 3/3)...
then i want out on my HTML like
Title:cash to purchase
bag:1 (ie(3/3)
Title:Offload
bag:4.5 (ie 9/2)
title:onroad
bag:5.5 (ie 11/2) ...were 2 is total t_id

How to keep single sql connection instance open for multiple request in c#? : I have web api which contains database insertion logic(ado.net) in c#. When multiple users(e.g. 100 users) call the web api, everytime sql connection is open and closed for multiple request. it slows down performance. How can I keep single sql connection live for multiple request? I have to keep sql connection open only once and close after some time so that during that time it should consider multiple request and insert records in database.
Please suggest.

Read files sent with spark-submit by the driver : <p>I am sending a Spark job to run on a remote cluster by running</p>
<pre><code>spark-submit ... --deploy-mode cluster --files some.properties ...

<p>I want to read the content of the <code>some.properties</code> file by the <strong>driver</strong> code, i.e. before creating the Spark context and launching RDD tasks. The file is copied to the remote driver, but not to the driver's working directory.</p>
<p>The ways around this problem that I know of are:</p>
<ol>
<li>Upload the file to HDFS</li>
<li>Store the file in the app jar</li>
</ol>
<p>Both are inconvenient since this file is frequently changed on the submitting dev machine.</p>
<p>Is there a way to read the file that was uploaded using the <code>--files</code> flag during the driver code main method? </p>

Why does create-react-app creates both App.js and index.js? : <p>I started learning React and now I'm trying to understand what is the purpose of the <code>index.js</code> and <code>App.js</code> which are created by by running <a href="https://github.com/facebook/create-react-app" rel="noreferrer">create-react-app</a>.</p>
<p>Why can't we just use, for example. <code>App.js</code>?</p>
<p>I've read that App.js usually used as a main entry point to the application, but auto-generated code of <code>index.js</code> seems like a part of main entry point:</p>

import registerServiceWorker from './registerServiceWorker';
ReactDOM.render(<App />, document.getElementById('root'));

golang mysql "connection refused" : I'm new in Go (Golang). Wrote a simple benchmark program to test the concurrent processing with mysql. Keep getting "dial tcp 52.55.254.165:3306: getsockopt: connection refused", "unexpected EOF" errors when I increase the number of concurrent channels.
Each go routine is doing a batch insert of 1 to n number of row to a simple customer table. The program allows to set variable insert size (number of rows in a single statement) and number of parallel go routine (each go routine performs one insert above). Program works fine with small numbers row<100 and number go routines<100. But start getting Unexpected EOF errors when the numbers increase, especially the number of parallel go routines.
Did search for clues. Based on them, I've set the database max connection and 'max_allowed_packet' and 'max_connections'. I've also set the go program db.db.SetMaxOpenConns(200), db.SetConnMaxLifetime(200), db.SetMaxIdleConns(10). I've experimented with big numbers and small (from 10 to 2000). Nothing seem to solve the program.
Help please!

differences between new and malloc in c++ : <pre><code>#include <iostream>
#include <cstdlib>
using namespace std;
class Box {
public:
Box() {
cout << "Constructor called!" <<endl;
}
void printer(int x)
{
cout<<x<<" printer"<<endl;
}
~Box() {
cout << "Destructor called!" <<endl;
}
};
int main( ) {
Box* myBoxArray = new Box[4];
Box* myBoxArray2 = (Box*)malloc(sizeof(Box[4]));
myBoxArray2->printer(23);
*myBoxArray2;
*(myBoxArray2).printer(23);
return 0;
}
</code></pre>
<p>the problem simply is that when i use 'new' the constructor is printed out but when i simple derefrence the pointer to <code>myBoxArray2</code> the constructor is not printed and neither is the funtion <code>printer</code> printed.
Also why is it that when i use <code>-></code> the funnction printer runs but not when i use the equivalent <code>*(myBoxArray2).printer(23)</code></p>

How to cancel DispatchQueue.main.asyncAfter(deadline: time) in Swift3? : <h2>Description:</h2>
<p>I'm currently using the following code to see if the user has stopped typing in the searchBar. I would like to cancel it everytime the user immediately starts typing after <code>0.5</code> seconds. </p>
<p><strong>Code:</strong></p>
<pre><code>DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
// your function here
}
</code></pre>
<h2>Question:</h2>
<p>How do I cancel <code>DispatchQueue.main.asyncAfter</code> if the user starts typing again in <code>Swift3</code> ?</p>
<h2>What I've tried:</h2>
<p>I previously tried implementing :</p>
<pre><code>NSObject.cancelPreviousPerformRequests(withTarget: self)
self.perform(Selector(("searchForText:")), with: searchString, afterDelay: 0.5)
</code></pre>
<p>However the delay does not seem to work properly. </p>
<p><strong>More code:</strong></p>
<pre><code>//In class SearchViewController: UITableViewController, UISearchResultsUpdating
func updateSearchResults(for searchController: UISearchController) {
let searchString: String = searchController.searchBar.text!
//This is what I previously tried.. which doesn't work...
//NSObject.cancelPreviousPerformRequests(withTarget: self)
//self.perform(Selector(("searchForText:")), with: searchString, afterDelay: 0.5)
//A struct with the first example code shown above.
Utils.Dispatch.delay(secondsToDelay: 1){

Accessing page with parameter returns HTML w/o CSS : I'm implementing pagination for the first time ever right now, though I have run into an issue.
When I access the website with a parameter (i.e. `mydomain.com/?page=2`) which is separated by a forward slash, it returns the page without any styling.
Accessing the page without the forward slash (i.e. `mydomain.com?page=2`) returns the page with styling, as expected.
However, I have read that the proper way to implement and use parameters is with the forward slash...
**Why is it returning a page without styling?**

Getting httpServletRequest attribute with MockMvc : <p>I have a really simple controller defined in this way:</p>
<pre><code>@RequestMapping(value = "/api/test", method = RequestMethod.GET, produces = "application/json")
public @ResponseBody Object getObject(HttpServletRequest req, HttpServletResponse res) {
Object userId = req.getAttribute("userId");
if (userId == null){
res.setStatus(HttpStatus.BAD_REQUEST.value());
}
[....]
}
</code></pre>
<p>I tried to call using MockMvc in many different way but, I'm not able to provide the attribute "userId". </p>
<p>For instance, with this it doesn't work:</p>
<pre><code>MockHttpSession mockHttpSession = new MockHttpSession();
mockHttpSession.setAttribute("userId", "TESTUSER");
mockMvc.perform(get("/api/test").session(mockHttpSession)).andExpect(status().is(200)).andReturn();
</code></pre>
<p>I also tried this, but without success:</p>
<pre><code>MvcResult result = mockMvc.perform(get("/api/test").with(new RequestPostProcessor() {
public MockHttpServletRequest postProcessRequest(MockHttpServletRequest request) {
request.setParameter("userId", "testUserId");
request.setRemoteUser("TESTUSER");
return request;
}
})).andExpect(status().is(200)).andReturn();
</code></pre>
<p>In this case, I can set the RemoteUser but never the Attributes map on HttpServletRequest. </p>
<p>Any clue?</p>

Cache a static file in memory forever on Nginx? : <p>I have Nginx running in a Docker container, and it serves some static files. The files will <em>never</em> change at runtime - if they actually do change, the container will be stopped, the image will be rebuilt, and a new container will be started.</p>
<p>So, to improve performance, it would be perfect if Nginx would read the static files only one single time from disk and then server it from memory forever. I have found some configuration options to configure caching, but at least from what I have seen none of them provided this "forever" behavior that I'm looking for.</p>
<p>Is this possible at all? If so, how do I need to configure Nginx to achieve this?</p>

Styling a Twitter feed - CSS won't target .timeline-Tweet-text : <p>I'm bringing a Twitter feed through to my site using the following code which is described on <a href="https://publish.twitter.com/" rel="noreferrer">https://publish.twitter.com/</a></p>
<pre><code><a class="twitter-timeline" href="https://twitter.com/ACCOUNT-HERE" data-tweet-limit="3">Tweets by</a>
<script async src="//platform.twitter.com/widgets.js" charset="utf-8"></script>
</code></pre>
<p>The feed is displayed correctly. However it uses CSS which is provided via Twitter.</p>
<p>When I inspect it using Chrome dev tools I can see the following classes around the Tweets:</p>
<pre><code><p class="timeline-Tweet-text" lang="en" dir="ltr">
</code></pre>
<p>So I thought it would be a simple case of targetting this in CSS, e.g.</p>
<pre><code>.timeline-Tweet-text {
}
</code></pre>
<p>However, this doesn't apply any styles to the Tweets. Why not?</p>
<p>I have also referred to Twitters guidance on this here <a href="https://dev.twitter.com/web/overview/css" rel="noreferrer">https://dev.twitter.com/web/overview/css</a> but that also doesn't work.</p>
<p>The only reason I want to do this is so the font used within the widget matches the font used by the rest of the <code>body</code> text on my website.</p>

Why strcmp() works differently in code blocks (particularly in gcc) and other compilers? : <p>I was just trying to execute this program in code blocks and i got an output of 0,1,-1 , in some other compiler i got result 0,4,-1 but according to the working of strcmp() , i should get 0,4,-32 , i am not able to understand why i am getting diferent outputs on different compilers.</p>
<pre><code>#include<stdio.h>
#include<string.h>
int main()
{
char string1[]="Jerry";
char string2[]="Ferry";
int i,j,k;
i=strcmp(string1,"Jerry");
j=strcmp(string1,string2);
k=strcmp(string1,"Jerry boy");
printf("%d %d %d \n",i,j,k);
return 0;

boolean function returning true when it shouldn't C++ : <p>I have a program that searches a binary search tree using breadth first search with each type of traversal. all my functions work and run but the last traversal, postorder traversal, returns true when searching a number that is not in the tree.

Can anyone tell me why? </p>

<p>Each of the other traversals correctly prints out 35 is in the tree, 29 is not in the tree. Only post order prints that 29 is in the tree even though true is never returned when 29 is being checked. Im sure i am missing something small and silly but i just cannot seem to find it.</p>

Share a dictionary of pandas dataframe across multiprocessing python : <p>I have a dictionary of python pandas dataframes. The total size of this dictionary is about 2GB. However, when I share it across 16 multiprocessing (in the subprocesses I only read the data of the dict without modifying it), it takes 32GB ram. So I would like to ask if it is possible for me to share this dictionary across multiprocessing without copying it. I tried to convert it to manager.dict(). But it seems it takes too long. What would be the most standard way to achieve this? Thank you.</p>

Image Upload Javascript : <p>My problem here is uploading images.. BUT I already know how to upload Base64 Images. Right now , i can upload Base64 Images and put them to databse. You can already see that is ridicolous as it will take tons of space and is hard to load. I was just checking if there is like this API Where you can upload and it gives you URL(And No I dont want Imgur, because it is banned a lot of places.) Or if there is a custom way to shorten Base64? Something that wont take as much space as Base64 Images do...</p>

c# adding money together removes the 0 at the end : <p>In c# when adding two decimals the program will automatically get rid of the number 0 after the decimal places. </p>
<p>For example adding 0.50 to 1.20 will produce the answer of 1.7 and this is annoying because i need to display this answer in terms of money. </p>
<p>Is there a way to prevent this?</p>

Use Cases of NIFI : <p>I have a question about Nifi and its capabilities as well as the appropriate use case for it. </p>
<p>I've read that Nifi is really aiming to create a space which allows for flow-based processing. After playing around with Nifi a bit, what I've also come to realize is it's capability to model/shape the data in a way that is useful for me. Is it fair to say that Nifi can also be used for data modeling?</p>
<p>Thanks!</p>

Go to a new view using SwiftUI : <p>I've got a basic view with a button using SwiftUI and I'm trying to present a new screen/view when the button is tapped. How do I do this? Am I suppose to create a delegate for this view that will tell the app's <code>SceneDelegate</code> to present a new view controller?</p>
<pre><code>import SwiftUI
struct ContentView : View {
var body: some View {
VStack {
Text("Hello World")
Button(action: {
//go to another view
}) {
Text("Do Something")
.font(.largeTitle)
.fontWeight(.ultraLight)

c# Capture image from screen and get colors : I'm making a program which can capture a small area on screen and will run something if there is any color on image that match the target colors. My program run as the following Sequence:
1/ Get image from a specific area from screen
2/ Save to a folder
3/ using CountPixel to detect any target_color
However, it through an exception at ""b.Save(@"C:\Applications\CaptureImage000.jpg", ImageFormat.Jpeg);"" after I click the "button5" twice times (not double click). Additional information: A generic error occurred in GDI+.
My questions are:
1. How can i fix this exception.
2. I want to use another method instead of CountPixel() to improve performance, because I just need to detect only one target color to rise event.
3. Step 2 is troublesome. I wonder if i can skip it and use the other way to call: (@"C:\Applications\CaptureImage000.jpg", ImageFormat.Jpeg) , because using this long string isn't comfortable and result error when im trying to use with GetPixel,... or add it into some "value example" code on internet for improvement purpose.
private int CountPixels(Bitmap bm, Color target_color)
{
// Loop through the pixels.
int matches = 0;
for (int y = 0; y < bm.Height; y++)
{
for (int x = 0; x < bm.Width; x++)
{
if (bm.GetPixel(x, y) == target_color) matches++;
}
}
return matches;
}
private Bitmap CapturedImage(int x, int y)
{
Bitmap b = new Bitmap(XX, YY);
Graphics g = Graphics.FromImage(b);
g.CopyFromScreen(x, y, 0, 0, new Size(XX, YY));
b.Save(@"C:\Applications\CaptureImage000.jpg", ImageFormat.Jpeg);
/* Run 3 line below will lead to question 1 - through exception

li padding not acting as it should : Can someone please explain why my padding is not acting as it should? My padding should be a perfect box, but for some reason it's coming out as some oblong rectangle. A padding of 30 all the way around the sides should be a perfect square. I have more rules for my other li and ul but that's for only in my '#nav' ID, so I don't see why there would be any conflict.
