R: readr: is it possible to read HTML tables using this package : <p>I want to know if we can reach html tables using readr package with the url of the page where html table is published. For example, I want to import table on the <a href="http://sports.yahoo.com/nfl/stats/byteam?group=Offense&cat=Total&conference=NFL&year=season_2010&sort=530&old_category=Total&old_group=Offense" rel="nofollow">page</a> to be loaded into R.</p>

Where to find some real programming assignments for a beginner webdev? : <p><strong>Hello, folks!</strong></p>
<p>So here I am - a total beginner in webdev without any profound education on the topic, but still aiming to get a real webdev job sometime soon. </p>
<p>And while the assignments in the courses I've taken employ practical use of the languages(HTML, CSS, PHP, JS, jQuery), they nevertheless lack real-life examples, like something that a real client might want. </p>
<p>Googling on programming challenges as to the aforementioned languages gave out mostly the same; I mean yes, there were some interesting things, but they're still far from the real clients' demand, IMO. </p>
<p><strong>So the question is:</strong> where can a beginning webdev find some real assignments to perform in order to comprehend the gist of modern webdev through practice and become able to answer the clients' possible demand? Just for the sake of experience, that is, payment is not obligatory. </p>
<p>Any links/replies will be greatly appreciated, thanks! </p>

Algorithm to find ideal starting spot in a circle : <p>So the problem I have been debating is as such:</p>
<p>Your are given an array of integers representing a circle. Then, you have to pick spot in the circle to start. From the place you start, you compare the value at the array to number of steps you took to get there and if the steps are less than or equal to the number, include it in your final set. Find the place to start so that you have the most elements in your set.</p>
<pre><code>ex, a=[0, 1, 2]
If you start at index=0, then:
a[0]=0 < =0 so 0 is included
a[1]=1 < =1 so 1 is included
a[2]=2 < =2 so 2 is included
final set: {0,1,2}
If you start at index=1, then:
a[1]=1 > 0 so 1 is NOT included
a[2]=2 > 1 so 2 is NOT included here we loop back around
a[0]=0 > 2 so 0 is included
final set: {0}
If you start at index=2, then:
a[2]=2 > 0 so 2 is NOT included, here we loop back around
a[0]=0 < = 1 so 0 is included
a[1]=1 < = 2 so 1 is included
final set: {0,1}
</code></pre>
<p>So in this trivial case, starting position index=0 is the best position as it results in the final set with the most elements. Now the brute force method of finding this is obvious, but I am trying to find a more efficient method. My attempts so far have been to examine trying to find the max intersect of viable starting ranges calculated for each element in the array. Also, I feel like dynamic programming can be used in some way to help make the solution but I can't seem to identify exactly how.</p>

Can you use a service worker with a self-signed certificate? : <p>I have developer server that are used for testing. They have SSL self-signed certificates, which allow us to test the web application over HTTPS, but with prominent warnings that the certificates are not verifiable.</p>
<p>That's fine, but I have a Service Worker that throws an error with the <code>navigator.serviceWorker.register</code></p>
<blockquote>
<p>SecurityError: Failed to register a ServiceWorker: An SSL certificate error occurred when fetching the script.</p>
</blockquote>
<p>How do I use a Service Worker with an intranet testing server which has a self-signed certificate?</p>

Reload current page in Aurelia : <p>I have an <a href="http://www.aurelia.io">Aurelia</a> application where the user can select the company they're currently "working on". Every page in the app is dependent on the currently selected company, and the user can select a new company from a drop-down menu. The drop-down is a component sitting on the nav-bar.</p>
<p>What I'd like is to have that component reload the current page on the <code>change.delegate</code> handler without restarting the app. So setting <code>window.location.href</code> is out of the question.</p>
<p><strong>Is there a way to force the aurelia <code>Router</code> to reload the current route/page?</strong></p>
<p>The alternative would be to use the <code>EventAggregator</code> to signal a company change throughout the app, but that would require either subscribing to that event on every page or having every page inherit from a base class that subscribes to that event, but these are much more involved options.</p>

How to remove lines from File A that are in File B using Windows powershell : <p><a href="https://stackoverflow.com/questions/19816914/how-to-join-two-text-files-removing-duplicates-in-windows">This other question</a> is excellent for joining two files. I need to do sort of the opposite. I need to remove lines from File A that are in File B, using powershell.</p>
<p><em>This</em> question is similar to <a href="https://stackoverflow.com/questions/21580073/delete-lines-from-file-a-that-is-in-file-b">this other question</a>, except that question is for unix and this is for Windows 7 powershell.</p>
<p>The files are hosts files. Each one has lines consisting of:</p>
<ul>
<li><code>127.0.0.1 host.domain.com</code></li>
</ul>
<p>or</p>
<ul>
<li><code>0.0.0.0 host.domain.com</code></li>
</ul>
<p>or</p>
<ul>
<li><code># this is a comment</code></li>
</ul>
<p>Files may have up to 200,000 lines. Spaces and tabs may be present.</p>
<p>Although I prefer it to be preserved, order does not effect function.</p>
<p>Here are some examples of hosts files:</p>
<ul>
<li><a href="https://adaway.org/hosts.txt" rel="nofollow noreferrer">https://adaway.org/hosts.txt</a></li>
<li><a href="https://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts&showintro=0&mimetype=plaintext" rel="nofollow noreferrer">https://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts&showintro=0&mimetype=plaintext</a></li>

</ol>
<p>or</p>
<ol start="2">
<li>Calling <code>FirebaseAnalytics.getInstance(Context)</code> once from <code>Application</code> class and keeping it around as a public static variable. Then, from everywhere I need this I can call `MyAppClass.mFirebaseAnalytics.logEvent()'.</li>

<p>Will any of the above methods have a undesired impact on the events that are automatically collected and/or do either of those have an efficiency gain over the other?</p>

Do I need to create a new SQLite database every time an application is updated? : <p>I have a Xamarin Forms application I would like to develop. It will have a SQLite database and I wish to make this available on iOS and Android. The database will be populated with data from a SQL Server database on the cloud with initial seed data. I'm thinking this will be about 500 rows of data with each row about 1Kb.</p>
<p>What I don't understand is when and how to populate this. Should I try to put the data into a CSV file and have this populate the database when the application is installed, or when it first starts? What's the normal way to populate seed data other than lines inside of the code with a huge number of insert statements. </p>
<p>Any help or advice on how this is normally done (I'm thinking most people do it the same way) would be much appreciated.</p>

React Router VS Conditional Rendering : <p>I am confused about the core difference (especially regarding performance) between using React Router and regular conditional rendering approach.
What I mean "regular conditional rendering approach" is, for example:</p>
<p>we can set a state in parent component, and pass it as children component's props,
we conditionally update such state depends on requirement, and children component will re-render as different content depends on its props.</p>
<p>I think it can achieve the exact same goal of using React Router, so why we still need React router? Is using react Router will bring much better performance experience or something (suppose we don't need history feature)?</p>

Move change each element in a string and a coditional if arr[i-1]=='n'.... do : problem take a string move every character in the alphabet 13 times forward for example hello would be **uryyb**, but the trick here is that if there is a vowel in the element before then its 14 spaces so it would be **urzyb**, I got the 14 space but then nothing else happens to the other letters so I keep getting **hezlo**, but if remove the // and use this line of code
message[i] = message[i] + key;`
then it doesn't do the 14 and only does 13 time can someone explain what I'm doing wrong and how to fix it
#include<stdio.h>
int main()
{
char message[100], ch;
int i, key;
printf("Enter a message to encrypt: ");
gets(message);
printf("Enter key: ");
scanf("%d", &key);
for(i = 0; message[i] != '\0'; ++i){
if(message[i] >= 'a' && message[i-1] <= 'z'){
if(message[i-1] == 'e'){
message[i]=message[i] + 14;
}
//message[i] = message[i] + key;
if(message[i] > 'z'){
message[i] = message[i] - 'z' + 'a'-1 ;
}
message[i] = message[i];
}
}
printf("Encrypted message: %s", message);
return 0;
}
Output is **hezlo**
should be **urzyb**

status bar disappeared after full screen video in WKWebView only in iOS 12 : <p>As you can see this only happened in iOS 12.</p>

override var preferredStatusBarStyle: UIStatusBarStyle {

override var prefersStatusBarHidden: Bool {

<p>Does anyone know how to solve it? </p>
<p>I know that if I set the key <code>View controller-based status bar appearance</code> to <code>YES</code> will help, but In that case it will look like this:</p>
<p><a href="https://i.stack.imgur.com/wk7OR.gif" rel="noreferrer"><img src="https://i.stack.imgur.com/wk7OR.gif" alt="enter image description here"></a></p>
<p>There are unknown reason for changing status bar from white and black, and as for my real project is in a large scale, so it will be nice to solve in the original setting, rather than make every ViewController inherit from one class which is subclass from UIViewController or add <code>dynamic</code> for overriding <code>prefersStatusBarHidden</code> and <code>preferredStatusBarStyle</code> in extension (here just try to force it show update status bar when <code>View controller-based status bar appearance</code> set to <code>YES</code>)</p>
<p>Hope there is a solution for <code>View controller-based status bar appearance</code> set to <code>NO</code>, that will be very helpful thx.</p>
<p><strong><a href="https://github.com/andrew54068/WebViewStatusBar" rel="noreferrer" title="demo project">here</a></strong> is the demo project, it was created by Xcode9.4, feel free to try it with.</p>

How to disable auto-quotes and auto-brackets in Jupyter 5.0 : <p>I upgraded Jupyter to the latest vesion, 5.0, and it looks like my front-end configuration stopped working.</p>
<p>I don't understand why Jupyter comes with auto closing quotes and brackets by default, which I find pretty annoying. So, at each version I have to change the settings to disable it.</p>
<p>It used to work by creating a file <code>~/.jupyter/custom/custom.js</code> and adding the next JavaScript code:</p>
<pre><code>require(['notebook/js/codecell'], function (codecell) {
codecell.CodeCell.options_default.cm_config.autoCloseBrackets = false;
})
</code></pre>
<p>I've read that since Jupyter 4 this code could be changed by:</p>
<pre><code>IPython.CodeCell.options_default.cm_config.autoCloseBrackets = false;
</code></pre>
<p>But it looks like in Jupyter 5, the two previous options stopped working.</p>
<p>The documentation I found regarding the front-end configuration is not helpful (I'll be happy to improve it once I understand it):</p>
<p><a href="http://jupyter-notebook.readthedocs.io/en/latest/frontend_config.html#frontend-config" rel="noreferrer">http://jupyter-notebook.readthedocs.io/en/latest/frontend_config.html#frontend-config</a></p>
<p>Can anyone help me understand how to disable auto-brackets and auto-quotes in Jupyter 5 please?</p>
<p>This is the exact version I'm running:</p>

Use module as text in Python : I have a dictionary that contains modules, now I would like to use the string value of the module (see example). Is this possible or am I better of just creating a second dictionary?
```python
import module1
import module2
import module3
module_dict = {
'module1' = module1
'module2' = module2
}
user_input = input()
module_dict[user_input].function()
#module3.function requires two strings to work, one of the string happens to be the name of the module
module3.function('foo', module_dict[user_input])
```
This is a really simplified version, forgive me if it looks confussing. I can not use the built-in ```str``` function since it will result in ```module 'modulename' at 'path'``` which is not what I am after. | 0debug |

The problem I am running into is that I only want to group by the product description and not other fields that I have to include because there are aggregate functions in the SELECT clause. I have googled and searched everywhere and have not found a simple solution. </p>

Is it considered grey/black hat SEO if I modify the sizing of the headings? : <p>The situation is the following:</p>
<p>The page's title is H3, the article's title is H2 and some keyword/important sentence is H1 in the article. They have custom css classes on them, so the H3 looks like a H1, and the H1 looks like normal text. Is this considered grey/black hat SEO, or Google doesn't care about their rendered size?</p>

Protobuf3: How to describe map of repeated string? : <p>The <a href="https://developers.google.com/protocol-buffers/docs/proto3#maps" rel="noreferrer" title="Official documentation about map type">Official documentation about map type</a> says:</p>
<blockquote>
<p><code>map<key_type, value_type> map_field = N;</code></p>
<p>...where the key_type can be any integral or string type (so, any
scalar type except for floating point types and bytes). The value_type
can be <strong>any type</strong>.</p>
</blockquote>
<p>I want to define a <code>map<string, repeated string></code> field, but it seems illegal on my <code>libprotoc 3.0.0</code>, which complains <code>Expected ">"</code>. So I wonder if there is any way to put repeated string into map.</p>
<p>A Possible workaround could be:</p>
<pre><code>message ListOfString {
repeated string value = 1;
}
// Then define:
map<string, ListOfString> mapToRepeatedString = 1;
</code></pre>
<p>But <code>ListOfString</code> here looks redundant. </p>

Fetching records from database in chunks : <p>My java web application is retrieving a large dataset from the DB (DB2) and displaying the records on a webpage.
Since the number of records is very large , the page takes a little time to load (about 15 secs)
To improve this , I want to implement pagination on the server side , ie fetch only 50 records at a time and show it on the page.
Then when the user clicks on Next , the next 50 records are fetched and displayed.</p>
<p>I have already implemented this on the client side ie I am showing the data in chunks of 50 , <strong>but I am still fetching the entire data in one database call</strong>, due to which the page takes time to load.</p>
<p>How can I implement the pagination on the server side ie fetch only 50 records at a time ?</p>
<p>Thanks in advance.</p>

Renaming RStudio project under version control : <p>What's the right way to rename an RStudio project (esp., when that project is under version control)?</p>
<p>E.g., I created an RStudio project with version control in "~/myproject". Then I decided I wanted to rename the project to "myproject1". So I </p>
<ol>
<li>renamed "~/myproject" as "~/myproject1"</li>
<li>renamed "myproject.Rproj" as "myproject1.Rproj"</li>
<li>committed the "rename" changes with git via RStudio.</li>
</ol>
<p>Everything seems to be fine. But I have a suspicion I'm missing something and that I'm going to be surprised by some project behavior down the line. </p>

c# creating a dynamically anonymous types (var) : <p>I need to create a anonymous type (HAS to be a var). Like this:</p>
<pre><code>var sizes = new {
size = new { Medium = "1", Large = "-3", XL = "10%" }
};
</code></pre>
<p>It has to be dynamically so the next time this could also happen:</p>
<pre><code>var sizes = new {
size = new { 3XL = "5", 4XL = "5%", 5XL = "-10%" }
};
</code></pre>
<p>How do I do this in C# winforms?</p>
<p>How do i fill in the var sizes? It has to be in this order!</p>

Determine if user clicked outside shadow dom : <p>I'm trying to implement a dropdown which you can click outside to close. The dropdown is part of a custom date input and is encapsulated inside the input's shadow DOM.</p>
<p>I want to write something like:</p>
<pre><code>window.addEventListener('mousedown', function (evt) {
if (!componentNode.contains(evt.target)) {
closeDropdown();
}
});
</code></pre>
<p>however, the event is retargeted, so <code>evt.target</code> is <em>always</em> the outside the element. There are multiple shadow boundaries that the event will cross before reaching the window, so there seems to be no way of actually knowing if the user clicked inside my component or not.</p>
<p><b>Note:</b> I'm not using polymer anywhere -- I need an answer which applies to generic shadow DOM, not a polymer specific hack.</p>

if (theSet.isEmpty) {
// do something here with theList and return a sequence

What is the reason I can't execute the code below? : <pre><code><?php
$greeting = 'hi';
echo 'hi' $greeting;
?>
</code></pre>
<p>I know that the above works when string interpolation is used such as <code>echo "hi $greeting";</code> but if the code works individually as in <code>echo 'hi'</code> and <code>echo $greeting</code> I don't understand why the I get an error when the code is combined to be <code>echo 'hi' $greeting;</code> as I illustrated above.</p>
