How to represent Guid in typescript? : <p>let's say I have this C# class</p>
<pre><code>public class Product
{
public Guid Id { get; set; }
public string ProductName { get; set; }
public Decimal Price { get; set; }
public int Level { get; set; }
}
</code></pre>
<p>The equivalent typescript would be something like:</p>
<pre><code>export class Product {
id: ???;
productName: string;
price: number;
level: number;
}
</code></pre>

CSS selector for all elements starting with a prefix : <p>I have several polymer elements.</p>
<pre><code><ps-el-one/>
<ps-el-two/>
<ps-el-three/>
<ps-el-four/>
</code></pre>
<p>I want to be able to query all of the elements which begin with "ps-" with either a CSS selector or javaScript.</p>
<p>I whipped up the following solution, but I am wondering if there is anything more efficient?</p>
<pre><code>var allElementsOnPage = document.querySelectorAll('*');
var res = [];
for (var index in allElementsOnPage) {
var el = allElementsOnPage[index];
if (el && el.tagName && el.tagName.substr(0, 3) == 'PS-') {
res.push(el);
}
}
</code></pre>
<p>This solution seems very inefficient.</p>

Stripe.setPublishableKey('stripe_key_here');
function stripeResponseHandler(status, response) {

// re-enable the submit button
$('.submit-button').removeAttr("disabled");
// show hidden div
document.getElementById('a_x200').style.display = 'block';
// show the errors on the form
$(".payment-errors").html(response.error.message);
} else {
var form$ = $("#payment-form");
// token contains id, last4, and card type
var token = response['id'];
var posted = document.getElementById("post-price").value
// insert the token into the form so it gets submitted to the server
form$.append("<input type='hidden' name='stripeToken' value='" + token + "' />");
form$.append("<input type='hidden' name='posted' value='" + posted + "' />");
// and submit
$("#payment-form").get(0).submit(function(e) {
e.preventDefault();

Immutability and collections : <p>Hello I've got a questation, is this bad approach to immutability? And if it is, why? I mean for me if you adding or removing items to or from collection, you are not changing the state of the object, it still has one and the same collection. It doesn't really matter how many and if collection has items when you itterating it. When you ask for it, you will get allways different reference which you can not modify. If this is bad practice where are pros in using immutable collections?</p>
<p>Thank you!</p>
<pre><code>using System;
using System.Collections.Generic;
class Test
{
private readonly List<object> items;
public object[] Items { get { return this.items.ToArray(); } }

this.items = new List<object>();
this.items.AddRange(items);
}

Variance Inflation Factor in Python : <p>I'm trying to calculate the variance inflation factor (VIF) for each column in a simple dataset in python: </p>
<pre><code>a b c d
1 2 4 4
1 2 6 3
2 3 7 4
3 2 8 5
4 1 9 4
</code></pre>
<p>I have already done this in R using the vif function from the <a href="https://cran.r-project.org/web/packages/usdm/usdm.pdf" rel="noreferrer">usdm library</a> which gives the following results:</p>
<pre><code>a <- c(1, 1, 2, 3, 4)
b <- c(2, 2, 3, 2, 1)
c <- c(4, 6, 7, 8, 9)
d <- c(4, 3, 4, 5, 4)
df <- data.frame(a, b, c, d)
vif_df <- vif(df)
print(vif_df)
Variables VIF
a 22.95
b 3.00
c 12.95
d 3.00
</code></pre>
<p>However, when I do the same in python using the <a href="http://statsmodels.sourceforge.net/devel/generated/statsmodels.stats.outliers_influence.variance_inflation_factor.html" rel="noreferrer">statsmodel vif function</a>, my results are:</p>
<pre><code>a = [1, 1, 2, 3, 4]
b = [2, 2, 3, 2, 1]
c = [4, 6, 7, 8, 9]
d = [4, 3, 4, 5, 4]
ck = np.column_stack([a, b, c, d])
vif = [variance_inflation_factor(ck, i) for i in range(ck.shape[1])]
print(vif)
Variables VIF
a 47.136986301369774
b 28.931506849315081
c 80.31506849315096
d 40.438356164383549
</code></pre>
<p>The results are vastly different, even though the inputs are the same. In general, results from the statsmodel VIF function seem to be wrong, but I'm not sure if this is because of the way I am calling it or if it is an issue with the function itself. </p>
<p>I was hoping someone could help me figure out whether I was incorrectly calling the statsmodel function or explain the discrepancies in the results. If it's an issue with the function then are there any VIF alternatives in python?</p>

How to convert node.js code to regular browser javascript? : <p>I don't know how to get a javascript file to work for web-browser functionalit, when it's coded as node.js.</p>
<p>The code in question is from a github <a href="https://github.com/svk31/graphenejs-lib" rel="noreferrer">graphenejs-lib</a>. I want to convert this node.js code into js:</p>
<pre><code>import {Apis} from "graphenejs-ws";
var {ChainStore} = require("graphenejs-lib");
Apis.instance("wss://bitshares.openledger.info/ws", true).init_promise.then((res) => {
console.log("connected to:", res[0].network);
ChainStore.init().then(() => {
ChainStore.subscribe(updateState);
});
});
let dynamicGlobal = null;
function updateState(object) {
dynamicGlobal = ChainStore.getObject("2.1.0");
console.log("ChainStore object update\n", dynamicGlobal ? dynamicGlobal.toJS() : dynamicGlobal);
}
</code></pre>
<p>There is another github from the same developer, <a href="https://github.com/svk31/steemjs-lib" rel="noreferrer">steemjs-lib</a>, that shows both the node.js use, and the browser use in the README default page.</p>
<p>I don't know how to make graphenejs-lib into browser javascript, like the steemjs-lib has been made into a regular javascript working version. I contact the dev, but have yet to receive a response.</p>
<p>I figured other people actually know how to do what the dev did for steemjs-lib, and get the graphenejs-lib to work in a browser.</p>
<p>Can you help me out? Thank you.</p>

addStyleClass("sapUiSizeCompact"); after clicking a button in UI5 : I want to change the compact density with a button.
onInit: function () {
this.getView().addStyleClass("sapUiSizeCompact");
},
works well. If I will change it in a button, it does not work.
onOpenDialog: function (oEvent) {
var oDialog1 = new sap.ui.commons.Dialog();
oDialog1.setTitle("App View Settings");
var oText = new sap.ui.commons.TextView({ text: "Compact Content Density:" });
oDialog1.addContent(oText);
var oToggleButton1 = new sap.ui.commons.ToggleButton({
text: "ON, press for OFF",
tooltip: "This is a test tooltip",
pressed: true,
press: function ()
{
if (oToggleButton1.getPressed()) {
oToggleButton1.setText("ON, press for OFF");
this.getView().addStyleClass("sapUiSizeCompact");
} else {
oToggleButton1.setText("OFF, press for ON");
this.getView().removeStyleClass("sapUiSizeCompact");
}
}
});
oDialog1.addContent(oToggleButton1);
oDialog1.addButton(new sap.ui.commons.Button({ text: "OK", press: function () { oDialog1.close(); } }));
oDialog1.open();
},
How can I point to the view from inside the function?
Thanks

cannot resolve symbol 'R' in android studio 3.3.1 : I am using android 3.3.1. I am currently taking an android development bootcamp online course on udemy. After I cloned the project from github to android studio (bitcoin-ticker), after the graddle files synchronize and project is loaded, when I open the MainActivity in java, I get R in red saying cannot resolve symbol 'R'. I didn't see a r class files in the project. So, I cleaned and built the project, android studio generated automatically the r class. I still had the cannot resolve symbol 'R' error. I moved the generated r class file to the same package where MainActivity java is with no result.
Here is a picture of what it looks. Does anyone know how can I get rid of the red R and get the project to compile?
Thanks in advance

Is there a way to share a configMap in kubernetes between namespaces? : <p>We are using one namespace for the develop environment and one for the staging environment. Inside each one of this namespaces we have several configMaps and secrets but there are a lot of share variables between the two environments so we will like to have a common file for those.</p>
<p>Is there a way to have a base configMap into the default namespace and refer to it using something like:</p>
<pre><code>- envFrom:
- configMapRef:
name: default.base-config-map
</code></pre>
<p>If this is not possible, is there no other way other than duplicate the variables through namespaces?</p>

How can I define macros for the C++ intellisense engine? : <p>When using the <code>"Default"</code> intellisense engine, some of the symbols in my C++ project cannot be resolved. It turns out that it's because they are in headers where they are guarded by an <code>#ifdef</code> that depends on a macro passed to gcc with the <code>-D</code> flag by the makefile. How can I tell the intellisense engine about these defines so that it is able to compile those parts of the header? </p>

[C++][SDL2]Segmentation fault before function entry, no apparent cause, can not find answer elsewhere : So, first I'll note that I am unable of finding a cause for this after an hour of debugging and googling. I have a function, that is supposed to load a few test assets and blit them onto screen using SDL2. This function throws a segfault immediately before executing any commands, with no clear cause. Keep in mind that some of the variables in this function are globals. I am very sorry for not commenting my code to make it easy to read but I will try to do so in the future.
Function contents:
printf("DEBUG");
int menuSelect = 0;
printf("declare");
SDL_Surface* bg = SDL_LoadBMP("menubg.bmp");
printf("bg load");
SDL_Surface* menu1 = TTF_RenderText_Solid(font,"HACKING PROGRAM",whiteclr);
printf("title blip");
SDL_BlitSurface(bg,NULL,screen,NULL);
printf("event");
SDL_Event* event;
printf("menu2");
SDL_Surface* menu2 = TTF_RenderText_Solid(font,"Hack",whiteclr);
printf("rect");
SDL_Rect menu2r = CreateRect(5,30,menu2->w,menu2->h);
printf("free");
SDL_FreeSurface(menu2);
SDL_FreeSurface(menu1);
while(SDL_WaitEvent(event))
{
switch(event->type)
{
case SDL_MOUSEBUTTONDOWN:
if(event->motion.x > menu2r.x && event->motion.x < menu2r.x+menu2r.w && event->motion.y > menu2r.y && event->motion.y < menu2r.y+menu2r.h)
{
SDL_FreeSurface(bg);
return 0;
}
break;
case SDL_MOUSEMOTION:
if(event->motion.x > menu2r.x && event->motion.x < menu2r.x+menu2r.w && event->motion.y > menu2r.y && event->motion.y < menu2r.y+menu2r.h)
{

}
else

}
break;

{
menu2 = TTF_RenderText_Solid(font,"Hack",selectclr);
}
else

now when I open the slide menu I see the hamburger icon visible .
my question is how I can make this hamburger icon invisible when the slide menu opens.
as you see above I have 2 id .one is side-bar and the other is open-slide.
which code I have to insert above in javascript or some condiitional code to make hamburger icon invisible when the slide menu opens. can you write to me all the javascript code to achieve my goal.

Styled-component vs jss vs emotion for React : <p>I'm trying to understand the best choice (as a CTO) between</p>
<ul>
<li>jss</li>
<li>emotion</li>
<li>styled-component.</li>
</ul>
<p>I will try not to make the question "too wide" or "off-topic", because it's a very subjective topic. I'll try to answer (here) the question myself if no-one answers the whole, and I'll ask very closed questions :</p>
<ul>
<li>How the three of them can "compile to" (external css, <code><style></code> tag, <code>style=</code> attributes) ?</li>
<li>How the three of them can integrate smoothly with CRA (without too much tweaks and without ejecting) ?</li>
<li>What about the OpenSource POV (age, community, plugins, backing) ?</li>
<li>What about the performance ?</li>
</ul>
<p>Please I don't want this question closed, so I don't want some code-style opinions, and I want to avoid subjectives POVs.</p>

How to join a table by a column with tilde separated values in sql server : I'm trying to match the codes/descriptions from table_2 to each company in table_1. The company_type_string column contains multiple codes separated by '~' that are supposed to match with the codes in table_2.
Table 1:
company company_type_string
A 1A~2B~3C
B 1A~2B
C 1A
D 1A~2B~3C~4D
Table 2:
code description
1A Finance
2B Law
3C Security
4D Marketing
Desired Outcome:
company description
A Finance
A Law
A Security
B Finance
B Law
C Finance
D Finance
D Law
D Security
D Marketing
I've tried using split_string with no success. Is there a way to make this join without altering the DB schema?

How to obtain a position of last non-zero element : <p>I've got a binary variable representing if event happened or not:</p>
<pre><code>event <- c(0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0)

<p>How can I obtain that with base R, tidyverse or any other way?</p>

Generating and accessing stored procedures using Entity framework core : <p>I am implementing Asp.Net core Web API , entity framework core, database first approach using Visual Studio 2017. I have managed to generate the context and class files based on an existing database. I need to access stored procedures using my context. In earlier version of entity framework it was simple by selecting the stored procedure objects in the wizard and generating an edmx that contains those objects. I could then access stored procedures via the complex type objects exposed by entity framework. How do I do a similar thing in entity framework core. An example would help ?</p>

What is `export type` in Typescript? : <p>I notice the following syntax in Typescript.</p>
<pre><code>export type feline = typeof cat;
</code></pre>
<p>As far as I know, <code>type</code> is not a <a href="https://www.typescriptlang.org/docs/handbook/basic-types.html" rel="noreferrer">built-in basic type</a>, nor it is an interface or class. Actually it looks more like a syntax for aliasing, which however I can't find reference to verify my guess.</p>
<p>So what does the above statement mean?</p>

Kotlin Map with non null values : <p>Let say that I have a Map for translating a letter of a playing card to an integer </p>

<p>When working with the map it seems that I always have to make a null safety check even though the Map and Pair are immutable:</p>
<pre><code>val difference = rank["Q"]!! - rank["K"]!!
</code></pre>
<p>I guess this comes from that generic types have Any? supertype. Why can't this be resolved at compile time when both Map and Pair are immutable?</p>

What exactly is the timeout value in React CSS Transition Group doing? : <p>I've been reading the official docs for <a href="https://facebook.github.io/react/docs/animation.html" rel="noreferrer">React Animations (React CSS Transition Group)</a>, but I'm a little unclear as to what the timeout values are used for - especially when I'm setting transitions within my CSS. Are the values a delay, duration of the animation, or how long that class is applied before being removed? And how do they relate to the duration of transitions set in my CSS? </p>
<p>For example, if I were to have a simple fade in/out when the component enters/leaves, I'd also set the opacity and transition duration within my CSS. Does the component then animated based on the timing passed in this value or the duration set within my CSS?</p>
<p>Here's an example provided by the official docs:</p>
<p><strong>My React Component</strong></p>
<pre><code><ReactCSSTransitionGroup
transitionName="example"
transitionEnterTimeout={500}
transitionLeaveTimeout={300}
>
{items}
</ReactCSSTransitionGroup>
</code></pre>
<p><strong>My .css file</strong></p>
<pre><code>.example-enter {
opacity: 0.01;
}
.example-enter.example-enter-active {
opacity: 1;
transition: opacity 500ms ease-in;
}
.example-leave {
opacity: 1;
}
.example-leave.example-leave-active {
opacity: 0.01;
transition: opacity 300ms ease-in;
}

C# Win Forms game. Ground Collision : I have tried searching for an answer but i have not found anything. I'm making this 2d game in c# where i want the player to be pulled down by the force which increases by gravity each time the function in called (inside a while loop). For some reason the code will not stop when the for loop is broken.
private void PhysicsLoop()
{
NowX = Convert.ToInt32(Math.Floor(Convert.ToDecimal(Player.x / 32)));
NowY = Convert.ToInt32(Math.Floor(Convert.ToDecimal(Player.y / 32)));
if (Block[NowX,NowY + 2].Collides == false)
{
Falling = true;
}
if (Falling == true)
{
force += Gravity;
for (int i = 0; i <= force; i++)
{
if (Block[NowX, NowY + 2].Collides == true)
{
Falling = false;
break;
}
else
{
Player.y += 1;
}
}
} else
{
}
}
Also, block is a 2d array of a class, player is a class which just holds an x, y ,width and height value. Thanks for helping in advance!

Every array should be a own row in the mysql database.
I'm not sure how to do this since every array has a custom name (0, 1, 2, ...).

specify sysctl values using docker-compose : <p>I am trying to set a few sysctl values.<br>
Basically the following </p>
<pre><code>sysctl -w \
net.ipv4.tcp_keepalive_time=300 \
net.ipv4.tcp_keepalive_intvl=60 \
net.ipv4.tcp_keepalive_probes=9
</code></pre>
<p>in a docker container.<br>
When log into to the container directly and execute the command, I get the following error</p>
<pre><code>sysctl: cannot stat /proc/sys/net/ipv4/tcp_keepalive_time: No such file or directory
sysctl: cannot stat /proc/sys/net/ipv4/tcp_keepalive_intvl: No such file or directory
sysctl: cannot stat /proc/sys/net/ipv4/tcp_keepalive_probes: No such file or directory
</code></pre>
<p>Then I found out the --sysctl option in <code>docker run</code> in <a href="https://docs.docker.com/engine/reference/commandline/run/" rel="noreferrer">here</a>
But I did not find the equivalent option via docker-compose.
I have few services that start by default so using docker run instead of docker-compose is not an option for me.</p>
<p>Anyone knows of a way to supply --sysctl options to the container via compose?</p>

PHP + MySQL/MariaDB + avoid race condition : <p>I've developed a web application using Apache, MySQL and PHP.</p>
<p>This web app allows multiple users' to login to the application.
Then, through the application, they have access to the Database.</p>
<p>Since race conditions may apply when two or more users try to SELECT/UPDATE/DELETE the same information (in my case a row of a Table), I am searching for the best way to avoid such race conditions.</p>
<p>I've tried using mysqli with setting autocommit to OFF and using SELECT .... FOR UPDATE, but this fails to work as -to my understanding- with PHP, each transaction commits automatically and each connection to the db is being auto released when the PHP -->html page is provided/loaded for the user.</p>
<p>After reading some posts, there seem to be two possible solutions for my problem :</p>
<ol>
<li><p>Use PDO. To my understanding PDO creates connections to the DB which are not released when the html page loads. Special precautions should be taken though as locks may remain if e.g. the user quits the page and the PDO connection has not been released...</p></li>
<li><p>Add a "locked" column in the corresponding table to flag locked rows. So e.g. when an UPDATE transaction may only be performed if the corresponding user has locked the row for editing. The other users shall not be allowed to modify.</p></li>
</ol>
<p>The main issue I may have with PDO is that I have to modify the PHP code in order to replace mysqli with PDO, where applicable.</p>
<p>The issue with the scenario 2 is that I need to also modify my DB schema, add additional coding for lock/unlock and also consider the possibility of "hanging" locked rows which may result in additional columns to be added in the table (e.g. to store the time the row was locked and the lockedBy information) and code as well (e.g. to run a Javascript at User side that will be updating the locked time so that the user continuously flags the row while using it...) </p>
<p>Your comments based on your experience would be highly appreciated!!!</p>
<p>Thank you.</p>
