No network interfaces on Debian 8 Lenovo install : <p>So I recently got the Lenovo x270, and installed Debian on it instead of the default Windows OS. I've come to find out WiFi, as well as ethernet are both shipped not working. I've tried to fix it, but nothing has worked so far. I switched from straight Debian 8 to Kali to see if it was just a problem in base Debian, but it wasn't. Laptop specs related to issue:</p>
<ul>
<li><p>Intel® Dual Band Wireless-AC 8265</p></li>
<li><p>Kali Linux (Kernel 4.0.0)</p></li>
<li><p>1 Ethernet port</p></li>
</ul>
<p>I installed the Intel drivers needed for the 8265 (<a href="http://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000005511.html" rel="nofollow noreferrer">http://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000005511.html</a>). However, this requires a kernel version of 4.6, which it doesn't seem I can get without apt-get which I can't use because I don't have internet.</p>
<p>I also attempted to manually add the ethernet using <a href="https://wiki.debian.org/NetworkConfiguration#Setting_up_an_Ethernet_Interface" rel="nofollow noreferrer">https://wiki.debian.org/NetworkConfiguration#Setting_up_an_Ethernet_Interface</a> and a few other sources I've now lost, but that didn't work either. The main problem I'm having is it seems you need internet to be able to install various packages that allow you to get internet, so I'm not sure what to do. Any ideas would be a great help. </p>
<p>Thank you.</p>

Difference between vert.x and RxJava : <p>We are evaluating reactive programming frameworks for one of our projects. I just went through vert.x tutorials. I checked RxJava presentation a bit. RxJava seemed more close to CompletableFuture. But despite the underlying patterns, both RxJava and Vert.x give access to non blocking programming. I am confused as to what is the difference between them. I will appreciate any help in this regard.</p>

Prevent decimal and numbers after from being removed when using (int)$var : I have a JSON object with order information in. Within this object is an amount for example `"amount" : "82.95"` I have this within a variable called `$amount` and I am using it within an array by doing `(int)$amoun`t. The problem with this is that it is removing the `.95` which is required. How can I get this value as an integer not string but retain the `.95`?
Example:
$amount = 82.95;
echo (int)$amount;
// Result = 82

Where is redux store saved? : <p>I was looking into how secure a redux application can be, I am storing certain values in redux store i.e. user token etc.. and tried to see if someone else could gain access to them via an xss attack for example, I checked sessionStorage, localStorage, cookies and it is not there, as well as it is not inside my app.js file (my bundle file), hence my question.</p>

what will be the logic in shell scripting : i have a test file. and suppose content is like this. i want to put this into an array separated by "semicolon" in shell script
History is the discovery, collection, organization, analysis, and presentation of information about past events. History can also mean a continuous typically; chronological record of important or public events or of a particular trend or institution. Scholars who write about history are called historians. It is a field of knowledge which uses a narrative to examine and analyse the sequence of events; and it sometimes attempts to objectively investigate the patterns of cause and effect that determine events;
expected output:
array[0] should print:

Find regions of similar color in image : <p>I've been working on this problem for some time now with little promising results. I am trying to split up an image into connected regions of similar color. (basically split a list of all the pixels into multiple groups (each group containing the coordinates of the pixels that belong to it and share a similar color).</p>
<p>For example:
<a href="http://unsplash.com/photos/SoC1ex6sI4w/" rel="noreferrer">http://unsplash.com/photos/SoC1ex6sI4w/</a></p>
<p>In this image the dark clouds at the top would probably fall into one group. Some of the grey rock on the mountain in another, and some of the orange grass in another. The snow would be another - the red of the backpack - etc.</p>
<p>I'm trying to design an algorithm that will be both accurate and efficient (it needs to run in a matter of ms on midrange laptop grade hardware)</p>
<hr>
<p>Below is what I have tried:</p>
<p>Using a connected component based algorithm to go through every pixel from top left scanning every line of pixels from left to right (and comparing the current pixel to the top pixel and left pixel). Using the CIEDE2000 color difference formula if the pixel at the top or left was within a certain range then it would be considered "similar" and part of the group.</p>
<p>This sort of worked - but the problem is it relies on color regions having sharp edges - if any color groups are connected by a soft gradient it will travel down that gradient and continue to "join" the pixels as the difference between the individual pixels being compared is small enough to be considered "similar".</p>
<p>To try to fix this I chose to set every visited pixel's color to the color of most "similar" adjacent pixel (either top or left). If there are no similar pixels than it retains it's original color. This somewhat fixes the issue of more blurred boundaries or soft edges because the first color of a new group will be "carried" along as the algorithm progresses and eventually the difference between that color and the current compared color will exceed the "similarity" threashold and no longer be part of that group.</p>
<p>Hopefully this is making sense. The problem is neither of these options are really working. On the image above what is returned are not clean groups but noisy fragmented groups that is not what I am looking for.</p>
<p>I'm not looking for code specifically - but more ideas as to how an algorithm could be structured to successfully combat this problem. Does anyone have ideas about this?</p>
<p>Thanks!</p>

Spark executors crash due to netty memory leak : <p>when running spark streaming app that consumes data from kafka topic with 100 partitions, and the streaming runs with 10 executors, 5 cores and 20GB RAM per executor, the executors crash with the following log:</p>
<blockquote>
<p>ERROR ResourceLeakDetector: LEAK: ByteBuf.release() was not called
before it's garbage-collected. Enable advanced leak reporting to find
out where the leak occurred.</p>
<p>ERROR YarnClusterScheduler: Lost executor 18 on worker23.oct.com:

<p><a href="https://issues.apache.org/jira/browse/SPARK-17380" rel="noreferrer">https://issues.apache.org/jira/browse/SPARK-17380</a></p>
<p>and someone wrote that after upgrading to spark 2.0.2 the problem was solved. however we use spark 2.1 as part of HDP 2.6. so I guess this bug wasn't solved in spark 2.1.</p>
<p>there's also someone who encountered this bug and wrote about it in spark user list but got no answer:</p>

<p>BTW - the streaming app doesn't call <code>cache()</code> or <code>persist()</code>, so no caching is involved whatsoever.</p>
<p>Did anyone encounter a streaming app that crashed on such bug?</p>

Wrap long template literal line to multiline without creating a new line in the string : <p>In es6 template literals, how can one wrap a long template literal to multiline without creating a new line in the string?</p>
<p>For example, if you do this:</p>
<pre><code>const text = `a very long string that just continues
and continues and continues`
</code></pre>
<p>Then it will create a new line symbol to the string, as interpreting it to have a new line. How can one wrap the long template literal to multiple lines without creating the newline?</p>

What is 'nul' in batch file? : I was curious to learn what is `nul`. It is usually used:
- When we want to hide output of a command. In this case, we say that "we redirected `STDOUT` and `STDERR` outout to nul (if we cpecify `2>&1`)".
- When we want to create a new file. Then we usually use `type nul > newfile.txt` or even `copy nul newfile.txt` as https://stackoverflow.com/q/210201 says.
But **what** is `nul`? My research only shows its usage.
I have also read [this](https://ss64.com/nt/syntax-redirection.html) great article from https://ss64.com which says:
> Create empty files using the `NUL` **device**.
So, `nul` is a device? If so, can someone explain it, please? Also, there is some confusion with `null`. What are their differences?

How can i visit my nodejs website without typing :8080 or :8000? : I have an ubuntu 16.04 server with plesk installed with nodejs because it is written in angular2.
At the moment I'm runing the page with `http-server .` on my ubuntu server.
When i'm typing the ip address with ip:8000 or www.page.de:8080 I can visit my page.
But when i just type the ip address or www.page.de I see only a white page.
How can i change this?

Rotate switched facet labels in ggplot2 facet_grid : <p>I would like to plot some barplots on top of each other using facet_grid:</p>
<pre><code>library(ggplot2)
df <- group_by(mpg, manufacturer) %>%
summarise(cty = mean(cty), hwy = mean(hwy)) %>%
ungroup()
df <- melt(df, id.vars = "manufacturer")
ggplot() +
geom_bar(data =df, aes(x = variable, y = value), stat = "identity") +
facet_grid(manufacturer ~ ., switch = "y")
</code></pre>
<p>I use the <code>switch</code>argument of <code>ggplot2::facet_grid()</code>to let the facet labels be displayed on the y-axis instead of on top of each facet. Problem is that the facet labels are plotted vertically and therefore cropped. Is there any way to plot the facet -labels horizontally? All the questions I found so far related to rotating the x-axis labels only, not the facet labels.</p>

I mean if nodes are 1,2,3,4,5,6......
1 is root, 2,3 are left and right childs of node 1.
4,5 are left and right childs of node 2. And 6 is left child of 3...like this

How to group by unique user ID and sort by latest messages ID? : <p>my message table</p>

<p>I want to group by my <code>message</code> table by <code>sender_user_id</code> unique and by last <code>message_id</code></p>

3 | hello world again | 1000 | 1200
4 | xyz | 1001 | 1200

<p>Because latest <code>message_id</code> for <code>sender_user_id</code> IS 3. This is in theory.</p>

<pre><code>SELECT * FROM message WHERE receiver_user_id = 1200
GROUP BY sender_user_id
ORDER BY message_id DESC

<p>then sorting.</p>

How to tail a docker log from the current position in the log without seeing the whole file or waiting for it to traverse the whole file : <p>If you use the coreutils tail command in Linux you have a -f option that lets you follow a log file from the logs current position (it does not go to the very beginning of the file and display everything).</p>
<p>Is this functionality available in docker logs without having to wait for it to traverse the whole log?</p>
<p>Maybe I am trying the wrong arguments for the options? Using the available documentation I have tried </p>
<pre><code>docker logs --since 1m somecontainer
</code></pre>
<p>and</p>
<pre><code>docker logs -f --since 1m somecontainer
</code></pre>
<p>It appears that it actually traverses the entire log file (which can take a long time) and then starts echoing to screen once it reaches the the time frame you specify. </p>
<p>Is there a way to just start tailing from the current point without waiting?
Is my best option to always log out to some external file and just tail that with the coreutils tail command?</p>

Get input of switch control via headphone jack on iOS : <p>As a little holiday project I want to control an app via an accessibility switch which is connected via 3,5mm headphone jack to the iOS device.</p>
<p>This is the switch and the plug:<a href="https://i.stack.imgur.com/63hTl.png" rel="noreferrer"><img src="https://i.stack.imgur.com/63hTl.png" alt="enter image description here"></a></p>
<p>My problem is that I don't have any clue what kind of signal is fired when I press the button - I assumed that it acts similar to a headphone's remote control.</p>
<p>Is there a way to measure the input of this or does anybody know how to get the input of the button on iOS?</p>

RECORD / NUMBER A FORMULA IN A CELL, NOT TO BE DELETED GOOGLE SPREADSHEET - APPSCRIPT : I'm new to this apps script and I'm trying to create a function that leaves a formula nested / recorded inside a cell since the database is used by people who are not experts in the formulation and this would prevent them from deleting the fomulations
The problem is that the formula I am trying to record in the cell contains quotes "" and when executing the script it marks me an error, when modifying the script and removing the quotes if it records the formula but with an error (because the quotes are missing)
I hope you can help me as I see they are experts in the subject.
The sequence that I have so far is this:
function myFunction() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];
var cell = sheet.getRange("H1");
cell.setFormula("=importrange("https://docs.google.com/spreadsheets/d/1boU9bEyqJkLbf895QavKEzeZ4sLle2qoqepeZeJVV8/edit#gid=0";"sucursal 0007!B4")");
}
[the error that you send me I understand that it is because of the quotes that are inside the formula][1]
when you remove the quotes if you save the formula on sheet 1 but with an error (because you do not have the quotes required by the formula)
[enter image description here][2]
[1]: https://i.stack.imgur.com/UGe3O.png
[2]: https://i.stack.imgur.com/cN1a9.png
the correct formula that I need is this:
=importrange("https://docs.google.com/spreadsheets/d/1bpUJbEyqJkALbf995QavKEzeZ4sLle2qoqepeZaJVV8/edit#gid=0";"sucursal 0007!B4")

Creating a Behavior for a continuously measurable phenomenon : <p>I would like to create a <code>Behavior t a</code> from an <code>IO a</code>, with the intended semantics that the IO action would be run every time the behavior is <code>sample</code>d:</p>
<pre><code>{- language FlexibleContexts #-}
import Reflex.Dom
import Control.Monad.Trans
onDemand :: (MonadWidget t m, MonadIO (PullM t)) => IO a -> m (Behavior t a)
</code></pre>
<p>I hoped I could do this by just executing the <code>measurement</code> in a <code>pull</code>:</p>
<pre><code>onDemand measure = return $ pull (liftIO measure)
</code></pre>
<p>However, the resulting <code>Behavior</code> never changes after an initial <code>measure</code>ment.</p>
<p>The workaround I could come up with was to create a dummy <code>Behavior</code> that changes "frequently enough" and then create a fake dependency on that:</p>
<pre><code>import Data.Time.Clock as Time
hold_ :: (MonadHold t m, Reflex t) => Event t a -> m (Behavior t ())
hold_ = hold () . (() <$)
onDemand :: (MonadWidget t m, MonadIO (PullM t)) => IO a -> m (Behavior t a)
onDemand measure = do
now <- liftIO Time.getCurrentTime
tick <- hold_ =<< tickLossy (1/1200) now
return $ pull $ do
_ <- sample tick
liftIO measure
</code></pre>
<p>This then works as expected; but since <code>Behavior</code>s can only be sampled on demand anyway, this shouldn't be necessary. </p>
<p>What is the correct way to create a <code>Behavior</code> for a continuous, observable-at-any-time phenomenon?</p>

Changing a Spring Joint's resting length in Unity3d : <p>According to Spring Joint's documentation, a spring's resting length (the length at which the spring won't try to pull or push together the two bodies it connects) is the distance that was calculated between the two bodies as the joint was created.</p>
<p>However, I'd like to be able to change this resting distance at runtime, and the documentation doesn't mention anything about how the length can be changed.</p>
<p>Is there anyway to accomplish this with Spring Joint? If not, how to create a spring with a set resting length (which can be changed in a script) with <strong>Configurable Joint</strong>?</p>

chrome not running an EventListener : I'm having an issue with chrome, I have tried to create a button that adds a new input tag when the button is pressed. Now the below code works totally fine on internet explorer however in chrome nothing happens at all.
I also get no errors on the console the function just doesn't seem to run.
I've tried replacing it with just the ` $("#addto").append(input1);` with `alert("hello world");` just to see if the code ran at all and it doesn't.

Pandas recalculate index after a concatenation : <p>I have a problem where I produce a pandas dataframe by concatenating along the row axis (stacking vertically). </p>
<p>Each of the constituent dataframes has an autogenerated index (ascending numbers). </p>
<p>After concatenation, my index is screwed up: it counts up to n (where n is the shape[0] of the corresponding dataframe), and restarts at zero at the next dataframe. </p>
<p>I am trying to "re-calculate the index, given the current order", or "re-index" (or so I thought). Turns out that isn't exactly what <code>DataFrame.reindex</code> seems to be doing. </p>
<hr>
<p>Here is what I tried to do:</p>
<pre><code>train_df = pd.concat(train_class_df_list)
train_df = train_df.reindex(index=[i for i in range(train_df.shape[0])])
</code></pre>
<p>It failed with "cannot reindex from a duplicate axis." I don't want to change the order of my data... just need to delete the old index and set up a new one, with the order of rows preserved. </p>

class B : public A {

class C : private A {
int C_a;
protected:
int C_b;
public:

<p>I know it has to be with access rights over vars and funcs, but doing all the tests i really can grasp it and i don't know when to apply public or private inheritance;</p>

Java compare array to variable : Brand new to Java, I am in the process of writing a program that has an array initialized, as well as a variable that is holding a single integer. What I am trying to do is have my program check the array and then check the variable and if the variable integer is within my array sopln my array and print it without the number that is in the variable. Here is a rough little example of what I currently have written up. Therefore I want the array to be printed without the 17. Stuck on what to do after what I have written.
public class Harrison7b
{
public static void main(String [] args)
{
int[]arrayA = {2,4,8,19,32,17,17,18,25,17};
for(int B = 17; B < arrayA.length - 1; B++)
{

ScrollView minHeight to take up all the space : <p>I have a <code>ScrollView</code> which content doesn't necessarily exceeds it's size. Let's say it's a form where, upon errors, it expands to add error messages and then it exceeds the <code>ScrollView</code> size and thus is why I'm using that scroll.</p>
<p>The thing is that I want the content to always be at least of the same size of the ScrollView. I'm aware of the <code>minHeight</code> property, but the only way I found to use it is re-rendering, which I'd like to avoid.</p>
<p>I'm using redux for state management and this is what I have</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code><ScrollView
contentContainerStyle={[ownStyles.container, {minHeight: this.props.scrollHeight}]}
style={this.props.style}
showsVerticalScrollIndicator={false}
onLayout={(event) => {
scrollHeight = event.nativeEvent.layout.height;
this.props.setScrollContentHeight(scrollHeight);
}}
></code></pre>
</div>
</div>
</p>
<p>Where the <code>this.props.setScrollContentHeight</code> triggers an action which enters the height on the state, and <code>this.props.scrollHeight</code> is said height. So that after the first render where the onLayout function is triggered, the state is updated with the ScrollView's <code>height</code>, which I then assign as <code>minHeight</code> to its content.</p>
<p>If I set the content's style to <code>flex: 1</code> then the ScrollView won't scroll.</p>
<p>Can you think of a way to avoid that second render for performance purposes?</p>
<p>Thank you!</p>

How to add "refs" dynamically with react hooks? : <p>So I have an array of data in and I am generating a list of components with that data. I'd like to have a ref on each generated element to calculate the height.
I know how to do it with a Class component, but I would like to do it with React Hooks.</p>
<p>Here is an example explaining what I want to do:</p>
<pre><code>import React, {useState, useCallback} from 'react'
const data = [
{
text: 'test1'
},
{
text: 'test2'
}
]
const Component = () => {
const [height, setHeight] = useState(0);
const measuredRef = useCallback(node => {
if (node !== null) {
setHeight(node.getBoundingClientRect().height);
}
}, []);
return (
<div>
{
data.map((item, index) =>
<div ref={measuredRef} key={index}>
{item.text}
</div>
)
}
</div>
)
}
</code></pre>

Styling a php variable in css using the <p> tags : <p>I am having lots of trouble trying to style a php variable within a css file. I am coding a simple exercise type website, but am stumped on what to do. I have made a log in system and I want the user's username to appear in the corner every time they log in. Here is my code</p>
<pre><code><!--header.php-->
<header>
<nav>
<div class="mainWrapper">
<ul>
<li><a href="index.php">Home</a></li>
<li><a href="forum.php">Forums</a></li>
</ul>
<div class="navLogin">
<?php
if (isset($_SESSION['u_id'])) {
echo '<p class="navUsername">'.$_SESSION['u_uid'].'</p><form action="Includes/logout.inc.php" method="POST">
<button type="submit" name="submit">Logout</button>
</form>';
} else {
echo '<form method="POST" action="Includes/login.inc.php">
<input type="text" name="uid" placeholder="Username/Email">
<input type="password" name="pwd" placeholder="Password">
<button type="submit" name="submit">Sign In</button>
</form><a href="Includes/signup.inc.php">Sign Up</a>';
};
?>
</div>
</div>
</nav>
</header>
</code></pre>
<p>and now the css:</p>
<pre><code>.navUsername {
font-size: 100px;}
</code></pre>
<p>I have researched online and they say to put the css within a php file, but in their examples they are using the variable as a parameter rather than styling the variable itself. </p>
