how to join multiple csv files without repetition? : <p>I have 3 csv files they all should have the same date column like that:</p>
<pre><code>file1.csv file2.csv file3.csv

How do you shift a signal to reference a virtual ground in an instrumentation amplifier? : <p>I'm working on a circuit that needs to amplify a signal based on a changing resistance. The hardware that I have to work with can only make an offset square wave, but I need an input that is centered around 0V. I have tried using an instrumentation amplifier with one voltage set as the excitation signal and the other is the virtual ground, but it still fails to center the signal.</p>
<p>Any ideas of what to do to shift the signal?<a href="https://i.stack.imgur.com/1XhlI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1XhlI.png" alt="circuit"></a></p>

How many Windows users have UTF-8 set as the code page? : <p>In my understanding, the use of Windows filesystem functions accepting bytes (those with an <code>A</code> suffix) is discouraged (I didn’t find an official deprecation notice, but for example <a href="https://bugs.python.org/issue13374" rel="nofollow noreferrer">Python</a> deprecated their use).</p>
<p>On Unix-derived systems, file names are stored as bytes. The encoding isn’t defined, but many systems are configured to interpret file names as UTF-8.</p>
<p>Since recently, it seems to be possible on Windows to set the code page to UTF-8. Is it possible to estimate how many Windows users have that code page set? Does it make sense to use the bytes-accepting filesystem API on Windows similar to how the POSIX API is used on Unix-derived systems (e.g. when porting some application from Linux to Windows)?</p>

What is the purpose of `nil` private methods in ruby? : <p>Using ruby 2.3, and pry REPL, I have this funny result I cannot understand:</p>

Is there a way to set default value of range input to be empty? : <p>I have a HTML5 range input</p>
<pre><code><input name="testing" type="range" min="0" max="10" step="1">

<p>When there is no attribute "value" set, it sets the default value to the middle (i.e. 5 in this case). Is there a way to make it empty so that I know if the user has actively input something?</p>
<p>I have another div for value display. At the beginning the value will be "?", so the user will know they haven't input anything. The problem is to prevent the input from submitting value to backend if value is not actively set.</p>

Concatenate NPM Script Commands? : <p>I understand that it's possible to chain NPM scripts with <code>&&</code>, <code>pre-</code> and <code>post-</code> hooks, but is it possible to simply separate lengthy script lines into a single, concatenated line?</p>
<p>For example, I'd like to convert this:</p>
<pre><code>"script": {
"build": "--many --commands --are --required --on --a --single --line"
}
</code></pre>
<p>into this:</p>
<pre><code>"script": {
"part1": "--many --commands",
"part2": "--are --required",
"part3": "--on --a",
"part4": "--single --line",
"build": "part1 + part2 + part3 + part4"
}
</code></pre>
<p>So when I enter <code>npm run build</code> it will merge all the parts of the command on one line.</p>
<p>I'm also familiar with config variables, but they are not a cross platform solution so I will avoid using them.</p>

Vue template or render function not defined yet I am using neither? : <p>This is my main javascript file:</p>
<pre><code>import Vue from 'vue'
new Vue({
el: '#app'
});
</code></pre>
<p>My HTML file:</p>
<pre><code><body>
<div id="app"></div>
<script src="{{ mix('/js/app.js') }}"></script>
</body>
</code></pre>
<p>Webpack configuration of Vue.js with the runtime build:</p>
<pre><code>alias: {
'vue$': 'vue/dist/vue.runtime.common.js'
}
</code></pre>
<p>I am still getting this well known error:</p>
<blockquote>
<p>[Vue warn]: Failed to mount component: template or render function not defined.
(found in root instance)</p>
</blockquote>
<p>How come when I don't even have a single thing inside my #app div where I mount Vue, I am still getting a render/template error? It says <code>found in root</code> but there is nothing to be found because it does not even have any content?</p>
<p>How am I suppose to mount if this does not work?</p>
<p><strong>Edit:</strong></p>
<p>I have tried it like this which seems to work:</p>
<pre><code>new Vue(App).$mount('#app');
</code></pre>
<p>It make sense because using the <code>el</code> property implies you are 'scanning' that dom element for any components and it's useless because the runtime build does not have a compiler. </p>
<p>Still it is an extremely strange error message to throw, especially when I have my entire #app div emptied out.</p>
<p>Hopefully somebody could confirm my thoughts.</p>

What does negative index mean in a data frame? : <p>Recently I read a R statement somewhere, which said:</p>
<pre><code>mtcars[-1]
</code></pre>
<p>What does -1 imply here? I do understand the following statement:</p>
<pre><code>mtcars[1]
</code></pre>
<p>which means select the first column from the data frame, but I just could not infer the negative sign in the index?</p>

Why are non-placement `new` and `delete` built into the language and not just regular functions? : <p>Why were the non-placement <a href="http://en.cppreference.com/w/cpp/language/new" rel="noreferrer"><code>new</code> expression</a> and the <a href="http://en.cppreference.com/w/cpp/language/delete" rel="noreferrer"><code>delete</code> expression</a> implemented as language built-in instead of regular functions?</p>
<p>If we have...</p>
<ul>
<li><p>a way of requesting/giving back memory to the OS</p></li>
<li><p>a way of explicitly invoking a constructor <em>(placement <code>new</code>)</em></p></li>
<li><p>a way of explicitly invoking a destructor <em>(<code>~T()</code>)</em></p></li>
</ul>
<p>...why couldn't non-placement <code>new</code> and <code>delete</code> just be regular functions in the Standard Library? Example:</p>
<pre><code>template <typename T, typename... Ts>
T* library_new(Ts&&... xs)
{
auto* ptr = /* request enough memory for `T` from OS */;
new (ptr) T(std::forward<Ts>(xs)...);
return ptr;
}
template <typename T>
void library_delete(T* ptr)
{
ptr->~T();
/* reclaim memory for `T` from OS */

Need help overriding a tostring method in Java : Ok, so on my assignment that I am working on, I have a file that has the instructions commented, and below that is the code I wrote. I think I am good on everything EXCEPT overriding the ToString method. I think I'm starting the line good, I just cant figure out how to get the output going.
These are the instructions:
// Instruction 4
//TODO: Override the toString() method to return the account number,
// account name, and account balance. The returned string should look
// like:
// Account: 10001 - General Expenses
// Balance: 450.67
This is what I have so far:
public String toString(){
return "Accounts: " + accountNumber + " " + accountName + " " + accountBalance;

difference between isNothing and (== Nothing) in Haskell? : <p>I'm confused about why the two functions below involving <code>Nothing</code> are different:</p>
<pre><code>coalesce m1 m2 = if isNothing m1 then m2 else m1
coalesce' m1 m2 = if (m1 == Nothing) then m2 else m1
</code></pre>
<p>The first one has type:</p>
<pre><code>λ> :t coalesce
coalesce :: Maybe a -> Maybe a -> Maybe a
</code></pre>
<p>as expected. But the second one has:</p>
<pre><code>λ> :t coalesce'
coalesce' :: Eq a => Maybe a -> Maybe a -> Maybe a
</code></pre>
<p>Why does using <code>(==Nothing)</code> introduce the <code>Eq a</code> constraint? </p>

firing different sensor threads which sends data to same socket : My obvious search related to my problem have been this link so far
http://stackoverflow.com/questions/1523916/how-to-handle-same-socket-in-different-threads but it didnt help me in my pursuit. I have several sensor threads which are fired at random intervals to a client socket which in turn sends that data to the server socket.But i get issue when the sensor threads are fired at the same time then the data of those threads mixed up.I dont want that behaviour to happen.I want all those threads to be fired distinctly without being fired at the same point at any time.Please suggest me methods in order to achieve this.I have been trying to put sleep on the sensor threads but i dont get the desired result
P.S-: I am emulating a test bench environment where the sensors are fired in different threads (as if attached to client socket) to send data to this client on a different topics to the broker.

How to fix 'Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist.' : <p>I recently uninstalled and reinstalled Postgres10. I then went to run a Node/Express/React application that relies on connecting to a Postgres database (and communicating with it using Sequelize). </p>
<p>Initially it could not connect to the database. I realized the uninstall process removed my old databases, so then I went and re-created a new one with the name that this application connects to. Then when I restarted the app (both server and client), front-end interaction with the database was working again like normal - writing new users and reading them for authentication etc.</p>
<p>However, I now have the following error in the Chrome Dev Tools console on every page-load of the app:</p>
<blockquote>
<p>Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist</p>
</blockquote>
<p>This error makes a reference to localhost/:1. When I hover over this, it shows <a href="http://localhost:3000/" rel="noreferrer">http://localhost:3000/</a>, the address I'm viewing the app at in the browser.</p>
<p>Anyone have an idea what is going on? Most of the other threads I've found that bring up this error seem to be related to someone trying to develop a Chrome Extension, and even then they tend to have very few responses.</p>

Resize an image without distortion OpenCV : <p>I am using python 3 and latest version of openCV. I am trying to resize an image using the resize function provided but after resizing the image is very distorted. Code :</p>

file = "/home/tanmay/Desktop/test_image.png"
img = cv2.imread(file , 0)
print(img.shape)
cv2.imshow('img' , img)
k = cv2.waitKey(0)
if k == 27:
cv2.destroyWindow('img')
resize_img = cv2.resize(img , (28 , 28))
cv2.imshow('img' , resize_img)
x = cv2.waitKey(0)
if x == 27:
cv2.destroyWindow('img')
</code></pre>
<p>The original image is 480 x 640 (RGB therefore i passed the 0 to get it to grayscale)</p>
<p>Is there any way i could resize it and avoid the distortion using OpenCV or any other library perhaps? I intend to make a handwritten digit recogniser and i have trained my neural network using the MNIST data therefore i need the image to be 28x28.</p>

Downloading website get requests : <p>I am working on a school project where we write a program that looks into a website, downloads all the GET requests made by that website, and then pulls those downloads into a local file. The website is not static as it has constantly changing information so I can't just run a scraper through it. Is there a way to use Java or C# so that I can programmatically do this? Also, I can't give you the website because it is under my professor's name and she only wants her students to use it for teaching purposes.</p>
<p>p.s. I know you can manually do this by inspecting the element of a page and choosing the network tab, but I am having issues doing this with a program.</p>

Webpack with requirejs/AMD : <p>I'm working on a new module for an existing project that still uses requireJS for module loading. I'm trying to use new technologies for my new module like webpack (which allows me to use es6 loaders using es6 imports). It seems like webpack can't reconcile with requireJS syntax. It will say things like: "Module not found: Error: Can't resolve in ".</p>
<p><strong>Problem</strong>: Webpack won't bundle files with requireJS/AMD syntax in them.<br>
<strong>Question</strong>: Is there any way to make webpack play nice with requireJS?</p>

Unable to trigger state restoration code for BLE on iOS : <p>I am trying to get my app to respond relaunch into the background is response to discovering an advertising peripheral.</p>
<p>The following code currently works in my app (in foreground + background, even after many hours of being backgrounded):</p>
<pre><code>[self.centralManager scanForPeripheralsWithServices:self.services options:nil];
</code></pre>
<p>Generally, my app does not have any pending connection requests, as I want to scan for new advertisements in the background. The following documentation leads me to believe that this is still possible:</p>
<blockquote>
<p><em>it is important to keep in mind that the app will be relaunched and restored if and only if it is pending on a specific Bluetooth event or action (like scanning, connecting, or a subscribed notification characteristic), and this event has occurred.</em> (from <a href="https://developer.apple.com/library/content/qa/qa1962/_index.html" rel="noreferrer">https://developer.apple.com/library/content/qa/qa1962/_index.html</a>)</p>
</blockquote>
<p>and</p>
<blockquote>
<p><em>The system keeps track of...The services the central manager was scanning for (and any scan options specified when the scan started)</em> (from <a href="https://developer.apple.com/library/content/documentation/NetworkingInternetWeb/Conceptual/CoreBluetooth_concepts/CoreBluetoothBackgroundProcessingForIOSApps/PerformingTasksWhileYourAppIsInTheBackground.html" rel="noreferrer">https://developer.apple.com/library/content/documentation/NetworkingInternetWeb/Conceptual/CoreBluetooth_concepts/CoreBluetoothBackgroundProcessingForIOSApps/PerformingTasksWhileYourAppIsInTheBackground.html</a>)</p>
</blockquote>
<h1>Implementation</h1>
<p>I am following the steps outlined in this last link ^ under the section "Adding Support for State Preservation and Restoration", by doing the following things:</p>
<ol>
<li><p>Instantiating the central manager as directed:</p>
<p>self.centralManager = [[CBCentralManager alloc] initWithDelegate:self queue:nil options:@{ CBCentralManagerOptionRestoreIdentifierKey:@"myCentralManagerIdentifier" }];</p></li>
<li><p>Reinstantiate Your Central and Peripheral Managers</p></li>
</ol>
<p>Here I've actually not done anything else, since <code>didFinishLaunchingWithOptions</code> is called and the central will be reinitialized with the same identifier. (Is there something else to be done here that I'm missing?)</p>
<ol start="3">
<li><p>Implementing the restoration function:</p>
<p>(void)centralManager:(CBCentralManager *)central willRestoreState:(NSDictionary *)state {
// Breakpoint set here but never reached...
NSLog(@"...");
}</p></li>
</ol>
<h1>How I am testing state preservation / restoration</h1>
<p>I have set a breakpoint in the restore function (from step 3) and also inserted an <code>NSLog</code>.</p>
<p>By clicking "stop", as suggested in <a href="https://stackoverflow.com/questions/33130124/how-to-trigger-core-bluetooth-state-preservation-and-restoration/33137848#33137848">How to trigger Core Bluetooth state preservation and restoration</a>, I was hoping that I could trigger the code by advertising with my peripheral as I would do normally (this discovery/connection flow is working perfectly when the app is running in the background). But nothing really happens that I can tell.</p>
<p>My general question is: why is the breakpoint not triggered / NSLogs not printed? Is there a preferred way to debug the restoration feature?</p>
<p>Finally, as a sanity check, am I reading the docs correctly that discovery of an advertising peripheral should trigger the re-launch of the app into the background for the app to handle?</p>

Swift default AlertViewController breaking constraints : <p>I am trying to use a default AlertViewController with style <strong>.actionSheet</strong>. For some reason, the alert causes a <strong>constraint error</strong>. As long as the alertController is not triggered (displayed) through a button, there are no constraint errors on the whole view. Could it be that this is a <strong>bug of Xcode?</strong></p>
<p>The exact error I get looks like this:</p>
<pre><code>2019-04-12 15:33:29.584076+0200 Appname[4688:39368] [LayoutConstraints] Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(
"<NSLayoutConstraint:0x6000025a1e50 UIView:0x7f88fcf6ce60.width == - 16 (active)>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x6000025a1e50 UIView:0x7f88fcf6ce60.width == - 16 (active)>
</code></pre>
<p>This is the code I use:</p>
<pre><code>@objc func changeProfileImageTapped(){
print("ChangeProfileImageButton tapped!")
let alert = UIAlertController(title: "Change your profile image", message: nil, preferredStyle: .actionSheet)
alert.addAction(UIAlertAction(title: "Photo Library", style: .default, handler: nil))
alert.addAction(UIAlertAction(title: "Online Stock Library", style: .default, handler: nil))
alert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
alert.view.tintColor = ColorCodes.logoPrimaryColor
self.present(alert, animated: true)
}
</code></pre>
<p>As you can see, it is <strong>very basic</strong>. That's why I am very confused about the strange behavior I get as this <strong>default implementation</strong> should not cause any errors, right?</p>
<p><a href="https://i.stack.imgur.com/FTZFV.png" rel="noreferrer"><img src="https://i.stack.imgur.com/FTZFV.png" alt="Output I get"></a></p>
<p>Although, through breaking the constraints, the alert displays properly on all screen sizes I would be really thankful for any help I get.</p>

How to use scikit-learn for Q&A chatbot : <p>I want to create a chatbot for question answering purposes. I have my set of questions and answers. I already got a bot that only uses nltk with keyword recognition, but it has its limits. I would like to use machine learning to have a better chatbot.
I know scikit-learn is the best available Python library for ML, but I just don't know how to use it. All the exemples on their website are more about data visualization and not for actual using. For example, <a href="http://scikit-learn.org/stable/auto_examples/classification/plot_digits_classification.html#sphx-glr-auto-examples-classification-plot-digits-classification-py" rel="nofollow noreferrer">this</a> example is "quite close" to mine, in the meaning that we have a dataset and want to classify.</p>
<p>What I want is to know ho to create my own model, like the iris one we can find in a lot of ML examples for noobs, but with my Q&A set. For example, I could have a table referencing the category of the question, its length, number of keywords, which ones, etc, but I don't know to do it. Then, I'm not sure which algorithm to use (I thought of KNN) but more importantly how to train the model and then use it for questions from user input.</p>
<p>Thank you guys.</p>
