39,718,268 | Why do const references extend the lifetime of rvalues? | <p>Why did the C++ committee decide that const references should extend the lifetime of temporaries?</p>
<p>This fact has already been discussed extensively online, including here on stackoverflow. The definitive resource explaining that this is the case is probably this GoTW:</p>
<p><a href="https://herbsutter.com/2008/01/01/gotw-88-a-candidate-for-the-most-important-const/" rel="noreferrer">GotW #88: A Candidate For the “Most Important const”</a></p>
<p>What was the rationale for this language feature? Is it known?</p>
<p>(The alternative would be that the lifetime of temporaries is not extended by any references.)</p>
<hr>
<p>My own pet theory for the rationale is that this behavior allows objects to hide implementation details. With this rule, a member function can switch between returning a value or a const reference to an already internally existent value without any change to client code. For example, a matrix class might be able to return row vectors and column vectors. To minimize copies, either one or the other could be returned as a reference depending on the implementation (row major vs column major). Whichever one cannot be returned by reference must be returned by making a copy and returning that value (if the returned vectors are contiguous). The library writer might want leeway to change the implementation in the future (row major vs column major) and prevent clients from writing code that strongly depends on if the implementation is row major or column major. By asking clients to accept return values as const ref, the matrix class can return either const refs or values without any change to client code. Regardless, if the original rationale is known, I would like to know it.</p>

<blockquote>
<p>atomic blocks can be nested</p>
</blockquote>
<p>This sound like a great feature, but in my use case I want the opposite: I want the transaction to be durable as soon as the block decorated with <code>@atomic()</code> gets left successfully.</p>
<p>Is there a way to ensure durability in django's transaction handling?</p>
<h1>Background</h1>
<p>Transaction are ACID. The "D" stands for durability. That's why I think transactions can't be nested without loosing feature "D".</p>
<p>Example: If the inner transaction is successful, but the outer transaction is not, then the outer and the inner transaction get rolled back. The result: The inner transaction was not durable.</p>
<p>I use PostgreSQL, but AFAIK this should not matter much.</p>

39,721,654 | Take ownership of parameter by rvalue-reference | <p>I want to make clear that the constructor of my class <code>A</code> will take ownership of the passed <code>Data</code> parameter. The obvious thing to do is take a <code>unique_ptr</code> by value:</p>

<blockquote>
<p>createMemoryHistory([options])</p>
<p>createMemoryHistory creates an in-memory history object that does not
interact with the browser URL. This is useful for when you need to

browser URL, such as when your application is embedded in an iframe.</p>

39,726,908 | JavaScript blinking eye animation | <p>I am currently trying to learn JavaScript and trying out a lot of stuff, but as for now, my JS skilly are still very limited.
I created a little game where there is a box with bunny heads which randomly appear and the user has to click them as fast as possible.</p>
<p>So I created the bunnies with an interval animation where the bunny closes and opens its eyes within every 2 seconds.
Now I feel kind of stupid, but i can't manage to get the animation working as I want it to. Now the bunny is just closing its eyes every 2 seconds and then opening them again every 2 seconds. However, I want it only to blink, meaning that the eyes should be closed just for an instant and then opened again, so that the bunny is blinking every 2 seconds.
And then I would also like it to randomly sometimes blink only once and sometimes blink twice.
Not sure if this is hella easy and I am just blind from hours of coding stuff and learning new things, but it seems that I might need your help here.</p>
<p><a href="https://jsfiddle.net/schakalwal/y390jcx8/">Here is a fiddle</a> of the whole thing as it is right now.</p>
<p>You can see the complete code that was used inside the fiddle. I did not want to post the whole website here in the code section, but the parts I believe are of interest for my animation.</p>
<p>Here is the js code for the blinking eyes:</p>
<pre><code>var eyeleft = document.getElementById("eyeleft");
var eyeright = document.getElementById("eyeright");
window.onload = setInterval(function() {
eyeleft.className = (eyeleft.className != 'closedeyeleft' ? 'closedeyeleft' : 'eyeleft');
eyeright.className = (eyeright.className != 'closedeyeright' ? 'closedeyeright' : 'eyeright');
}, 2000);
</code></pre>
<p>Next the HTML</p>
<pre><code><div id="shape" class="game-shapes">
<div class="ears left"></div>
<div class="ears right"></div>
<div id="eyeleft" class="eyeleft"></div>
<div id="eyeright" class="eyeright"></div>
<div id="mouth">

<p>I've placed 2 couples of lines that would be supposed to be equal (in my attempts), with the if, because the first 2 lines in if are actually available in iOS9> only, while I'm attempting to do the same thing in the else statement, for every device (starting from iOS 8).</p>
<p>This is what I get:</p>
<p>iOS9+ at left, iOS8+ at right. Transparent background was colored red to show what happens (don't mind at different height in the images, they're equal height in app, instead look at added margins at left and right)</p>

<p>I want to analyze each block of numbers separately. I.e. here I have two blocks of numbers and want to perform the same analysis on them separately.</p>
<p>I know how I would implement this in Python, I just don't know how it looks in C++.</p>
<pre><code>file = open('data.text')
w = []
x = []
y = []
z = []
for line in file:
line = line.strip()
data = line.split()
w.append(data[0])
x.append(data[1])
y.append(data[2])
z.append(data[3])
file.close()
</code></pre>
<p>I also want to perform an analysis on the block of numbers, comparing all possibilities of two lines at once. In Python it would look something like (I guess -- haven't tried):</p>
<pre><code>r = []
s = []
t = []
for i in range(len(w)):
for j in range(len(w) - 1):
r.append(w[i]*x[j] - w[j]*x[i])
s.append(x[j]*y[i] - y[j]*x[i])
for i in range(len(w):
for j in range(len(s)):
t.append(s[j]*w[i] + r[j]*x[i])
best = min(t)
</code></pre>
<p>Here are a couple of the issues I've had in trying this with C++: I do not know the number of rows for the data (call it n), although I do know the number of blocks of numbers I want to analyze (call it N -- in my example N = 2). And plenty of segmentation faults. I think I can store the data, but I can't seem to call it. I create a class Data data and work from there.</p>
<pre><code>double get_data = 0;
for (std::string line; (std::getline(file,line));)
{
std::istringstream row(line);
Data data;
row >> data.w >> data.x >> data.y >> data.z;
std::vector<double> wcol;
std::vector<double> xcol;
std::vector<double> ycol;
std::vector<double> zcol;
get_data++;
for (int j = 0; j < get_data - 1; j++) {
if(data.w > 0)
{
wcol.push_back(data.w);
xcol.push_back(data.x);
ycol.push_back(data.y);
zcol.push_back(data.z);
}
get_data = 0;
}
</code></pre>
<p>But again I don't really know what I'm doing with C++.</p>
<hr>
<p>Maybe this should be a separate question, but I'd also like to break out of the analysis and then restart it for the next block of numbers. </p>

39,734,796 | JPA concurrency issue "On release of batch it still contained JDBC statements" | <p>I have a a concurrency issue I tried to solve with a while loop that attempts to save an entity multiple times until it hits some max retry count. I'd like to avoid talking about whether or not there are other ways to solve this problem. I have other Stackoverflow posts about that. :) Long story short: there's a unique constraint on a column that is derived and includes a numeric portion that keeps incrementing to avoid collisions. In a loop, I:</p>
<ol>
<li>select max(some_value)</li>
<li>increment the result</li>
<li>attempt to save new object with this new result</li>
<li>explicitly flush the entity and, if that fails because of the unique index, I catch a DataAccessException.</li>
</ol>
<p>All of this seems to work except when the loop goes back to step 1 and tries to select, I get:</p>
<pre><code>17:20:46,111 INFO [org.hibernate.engine.jdbc.batch.internal.AbstractBatchImpl] (http-localhost/127.0.0.1:8080-3) HHH000010: On release of batch it still contained JDBC statements

</code></pre>
<p>And a new Exception is caught. It seems like the first flush that causes the unique constraint violation and throws the <code>DataAccessException</code> doesn't clear the entity manager's batch. What's the appropriate way to deal with this? I'm using Spring with JPA and don't have direct access to the entity manager.

39,735,147 | How to color `matplotlib` scatterplot using a continuous value [`seaborn` color palettes?] | <p>I have a scatterplot and I want to color it based on another value (naively assigned to <code>np.random.random()</code> in this case). </p>
<p><strong>Is there a way to use <code>seaborn</code> to map a continuous value (not directly associated with the data being plotted) for each point to a value along a continuous gradient in <code>seaborn</code>?</strong> </p>
<p>Here's my code to generate the data:</p>
<pre><code>import numpy as np

import matplotlib.pyplot as plt
from sklearn.datasets import load_iris
from sklearn.preprocessing import StandardScaler
from sklearn import decomposition
import seaborn as sns; sns.set_style("whitegrid", {'axes.grid' : False})
%matplotlib inline
np.random.seed(0)
# Iris dataset
DF_data = pd.DataFrame(load_iris().data,
index = ["iris_%d" % i for i in range(load_iris().data.shape[0])],
columns = load_iris().feature_names)
Se_targets = pd.Series(load_iris().target,
index = ["iris_%d" % i for i in range(load_iris().data.shape[0])],
name = "Species")
# Scaling mean = 0, var = 1

# Sklearn for Principal Componenet Analysis
# Dims
m = DF_standard.shape[1]
K = 2
# PCA (How I tend to set it up)
Mod_PCA = decomposition.PCA(n_components=m)
DF_PCA = pd.DataFrame(Mod_PCA.fit_transform(DF_standard),
columns=["PC%d" % k for k in range(1,m + 1)]).iloc[:,:K]
# Plot
fig, ax = plt.subplots()
ax.scatter(x=DF_PCA["PC1"], y=DF_PCA["PC2"], color="k")
ax.set_title("No Coloring")
</code></pre>
<p><a href="https://i.stack.imgur.com/qh5LW.png" rel="noreferrer"><img src="https://i.stack.imgur.com/qh5LW.png" alt="enter image description here"></a></p>
<p>Ideally, I wanted to do something like this:</p>
<pre><code># Color classes
cmap = {obsv_id:np.random.random() for obsv_id in DF_PCA.index}
# Plot
fig, ax = plt.subplots()
ax.scatter(x=DF_PCA["PC1"], y=DF_PCA["PC2"], color=[cmap[obsv_id] for obsv_id in DF_PCA.index])
ax.set_title("With Coloring")
# ValueError: to_rgba: Invalid rgba arg "0.2965562650640299"
# to_rgb: Invalid rgb arg "0.2965562650640299"
# cannot convert argument to rgb sequence
</code></pre>
<p>but it didn't like the continuous value.</p>
<p>I want to use a color palette like:</p>
<pre><code>sns.palplot(sns.cubehelix_palette(8))
</code></pre>
<p><a href="https://i.stack.imgur.com/nVxYv.png" rel="noreferrer"><img src="https://i.stack.imgur.com/nVxYv.png" alt="enter image description here"></a></p>
<p>I also tried doing something like below, but it wouldn't make sense b/c it doesn't know which values I used in my <code>cmap</code> dictionary above:</p>
<pre><code>ax.scatter(x=DF_PCA["PC1"], y=DF_PCA["PC2"],cmap=sns.cubehelix_palette(as_cmap=True)

39,736,640 | Simplest and quickest way to portray an application for development | <p>As a designer I sometimes feel the need to portray the main idea of an application in a graphical form like a flowchart. Something that is easy enough to understand for the development firms and could convey the purpose of the application and possibly the main features it needs to provide which they could ultimately use to reply back with recommendations, rough estimates and turn around times.</p>
<p>The application will still be in the ideation phase so creating a prototype is an overkill. I could do it as a flowchart but I thought there should already be a conventional way professionals follow instead of going through meetings or typing up the details. </p>
<p>How do you go about doing this? If flowchart is the way to go then what type of flowcharts work best here? I just need the initial direction so I could start my research. </p>
<p>For example for an application with 3 different sets of dashboards for customers, providers and admins how can I demonstrate the rough logic that connects all functions between these 3 type of users?</p>

<p>None of this is my code or code from 3rd party developer libraries that I'm using, and doing a search on those variable names (i.e: 'uniqueId' or 'ABCDInfo') does not pull anything up, indicating it's not in my project.</p>

<p>If I use postman and send to that action a json like this {val: 15.30}, then val in the action recives a 0 (binding not working because of the culture). If I send a json like this {val: 15,30} then in the action I recive 15.30
The problem I have is, I need the action to accept decimals with commas, because that is the format that comes from inputs type text in the app's forms. But i also need to accept decimal with a dot that comes from request in json format. There is no way to specify a decimal/float in json that accepts a comma (send it as string is not an option). How can I do this??? I'm driving my self crazy with this.</p>

39,743,643 | npm package.json main and project structure | <p>I have a issue with npm and the main field. I see the documentation and as of my understanding I point main to be a different entry point than ./index.js. I already tested the package where all dist files are inside the root folder. I ignore src and test during pack phase using .npmignore but I did not like the point that building and packing the project to verify the structure pul all my files into the package root folder. So i changed the output to be dist instead.</p>
<p>If i use npm pack and extract the file I get the following structure:</p>
<pre><code>/
dist
-- index.js
-- moduleA
-- index.js
package.json
README.md
</code></pre>
<p>So for so good. But now I am forced to import it as follows:</p>
<pre><code>import {moduleA} from "myNpmModule/dist/moduleA";
</code></pre>
<p>But I dont want to have the dist folder in my import. So I set main in package.json</p>
<pre><code>"main": "dist/index.js"
</code></pre>
<p>But still it does not work and only works if I import with dist.
I use npm 3.10.7 and node 6.7.0.</p>
<p>Can anyone help?</p>

39,747,246 | Angular 2 get current route in guard | <p>I have an AccessGuard class in my project which its work is to determine if user can access to the route or not. I used the <code>router.url</code> to get the current route but the url returns the route before navigation to the new route like I'm in the users route and I click on the candidates route so the url returns users instead of candidates which I want that to validate access to the route
this is my route file:</p>
<pre><code>const routes:Routes = [

39,749,015 | apple-mobile-web-app-status-bar-style in ios 10 | <p>I know this question has been asked previously, just want to know if this is still the case in ios 10 (and ios 9)...</p>
<p>According to the apple developer guidelines for web apps (<a href="https://developer.apple.com/library/content/documentation/AppleApplications/Reference/SafariHTMLRef/Articles/MetaTags.html" rel="noreferrer">found here</a>), there are 3 choices for the status bar in a web app; <strong>default</strong>, <strong>black</strong> and <strong>black-translucent</strong>.</p>
<ol>
<li><strong>Default</strong> results in a white status bar with black text,</li>
<li><strong>Black</strong> results in a black status bar with white text, and</li>
<li><strong>Black-translucent</strong> results in a transparent background with white
text. Additionally, this status bar floats above your content,
meaning you have to push your content down 20px in order to not have
the content overlap with thte status bar text.</li>
</ol>
<p>I'd really like to use the black-translucent status bar (as I think it looks more native), but the background of my page is a light grey. This makes the white text on this status bar very hard to read.</p>
<p>Put simply, I'd just like a transparent background with black text (essentially, <strong>default-translucent</strong>). Is this possible?</p>

<p>I tried it instead and it did the same thing basically. Only thing is i do know how include works but i don't really know what extends does.

<p>Chrome console shows me a long list timeout errors like <code>GET https://..... net::ERR_TIMED_OUT</code>. </p>
<p>I was wondering if there is any way to change timeout settings in Chrome.</p>

39,751,421 | mountPath overrides the rest of the files in that same folder | <p>I have a volume with a secret called config-volume. I want to have that file in the /home/code/config folder, which is where the rest of the configuration files are. For that, I mount it as this:</p>
<pre><code>volumeMounts:
- name: config-volumes
- mountPath: /home/code/config
</code></pre>
<p>The issue is that, after deploying, in the /home/code/config I only have the secret file and the rest of them are gone</p>
<p>So the /home/code/config is an existing folder (not empty), I suspect that the volumeMount overwrites the folder.</p>
<p>Is there a way that this can be done without overwriting everything?</p>

39,752,434 | Python - merge two CSV files and KEEP duplicates | I am trying to merge two csv files and keep duplicate records. Each file may have a matching record, one file may have duplicate records (same student ID with different test scores), and one file may not have a matching student record in the other file.

I've looked through many threads and all address removing duplicates but I need to keep duplicate records.
