Why does std::make_pair not return a pair?

I have no idea why. How can I make this work? I have a function that returns a pair or tuple depending on the arguments passed to it and would like to verify it actually returns a pair or tuple in the correct cases.</p>

I a single list it is working, but in a column, it is not for some reason.</p> <p>I am trying this on windows 10 in anaconda , jupyter notebook </p> <p>I am trying to turn this:</p> <pre><code>lst = ['55.7492,12.5405', '55.7492,12.5405', '55.7492,12.5406', '55.7492,12.5406'] </code></pre> <p>into this </p> <pre><code>lst = [[55.7492,12.5405], [55.7492,12.5405], [55.7492,12.5406], [55.7492,12.5406]] </code></pre> <p>I have a column with a lot of those in a csv file.</p> <p>I tryed to turn them like this:</p> <pre><code> [[x] for x in lst] [['55.7492,12.5405'], ['55.7492,12.5405'], ['55.7492,12.5406'], ['55.7492,12.5406']] </code></pre> <p>So its working find outside of the csv but when I try to do it for every box in the colomn:</p> <pre><code>for stuff in data['column']: [[x] for x in stuff] for stuff in data_train['locations']: [map(int,x.split()) for x in stuff] </code></pre> <p>Nothing changes in the column .</p>

Make a button image change when pressed / focused / disabled : <p>I have several pictures of the same button, each one representing it in a different sate: normal, pressed, focused, disabled.</p> <p>How can I make it into an html button that automatically shows the correct picture (and also has an onClick event) ?</p> <p>Feel free to use html / css / javascript. </p> <p>The tag also doesn't need to be a button, it could be an image, , or whatever you want, but hopefully written in a generic enough way for others to use your solution too</p> <p>Thanks!</p>

Finding the minimum and maximum value within a Metal texture : <p>I have a <code>MTLTexture</code> containing 16bit unsigned integers (<code>MTLPixelFormatR16Uint</code>). The values range from about 7000 to 20000, with 0 being used as a 'nodata' value, which is why it is skipped in the code below. I'd like to find the minimum and maximum values so I can rescale these values between 0-255. Ultimately I'll be looking to base the minimum and maximum values on a histogram of the data (it has some outliers), but for now I'm stuck on simply extracting the min/max.</p> <p><em>I can read the data from the GPU to CPU and pull the min/max values out but would prefer to perform this task on the GPU.</em></p> <p><strong>First attempt</strong></p> <p>The command encoder is dispatched with 16x16 threads per thread group, the number of thread groups is based on the texture size (eg; width = textureWidth / 16, height = textureHeight / 16).</p> <pre><code>typedef struct { atomic_uint min; atomic_uint max; } BandMinMax; kernel void minMax(texture2d&lt;ushort, access::read&gt; band1 [[texture(0)]], device BandMinMax &amp;out [[buffer(0)]], uint2 gid [[thread_position_in_grid]]) { ushort value = band1.read(gid).r; if (value != 0) { uint currentMin = atomic_load_explicit(&amp;out.min, memory_order_relaxed); uint currentMax = atomic_load_explicit(&amp;out.max, memory_order_relaxed); if (value &gt; currentMax) { atomic_store_explicit(&amp;out.max, value, memory_order_relaxed); } if (value &lt; currentMin) { atomic_store_explicit(&amp;out.min, value, memory_order_relaxed); } } } </code></pre> <p>From this I get a minimum and maximum value, but for the same dataset the min and max will often return different values. Fairly certain this is the min and max from a single thread when there are multiple threads running.</p> <p><strong>Second attempt</strong></p> <p>Building on the previous attempt, this time I'm storing the individual min/max values from each thread, all 256 (16x16).</p> <pre><code>kernel void minMax(texture2d&lt;ushort, access::read&gt; band1 [[texture(0)]], device BandMinMax *out [[buffer(0)]], uint2 gid [[thread_position_in_grid]], uint tid [[ thread_index_in_threadgroup ]]) { ushort value = band1.read(gid).r; if (value != 0) { uint currentMin = atomic_load_explicit(&amp;out[tid].min, memory_order_relaxed); uint currentMax = atomic_load_explicit(&amp;out[tid].max, memory_order_relaxed); if (value &gt; currentMax) { atomic_store_explicit(&amp;out[tid].max, value, memory_order_relaxed); } if (value &lt; currentMin) { atomic_store_explicit(&amp;out[tid].min, value, memory_order_relaxed); } } } </code></pre> <p>This returns an array containing 256 sets of min/max values. From these I guess I could find the lowest of the minimum values, but this seems like a poor approach. Would appreciate a pointer in the right direction, thanks!</p>

Basemap with Python 3.5 Anaconda on Windows : <p>I use Python 3.5 with latest version of Anaconda on Windows (64 bit). I wanted to install Basemap using <code>conda install basemap</code>.

What would then be the simplest alternative solution?</p> <ul> <li>Is there an alternative package similar to basemap for ploting maps, etc.?</li> <li>Should I use a second environment which uses Python 2 and basemap? I have never done that but it seems possible (<a href="http://conda.pydata.org/docs/py2or3.html" rel="noreferrer">http://conda.pydata.org/docs/py2or3.html</a>). Is it "safe"? Should I install again all the other packages (matplotlib, numpy, etc.) on the second environment? </li> </ul> <p>Thanks in advance for the help and advice. </p>

You can also refer to my Github project [Jersey-Spring-Hibernate-Project][1] [1]:https://github.com/prayagkr/Jersey-Spring-Hibernate-Project . ---------- To setup our project we need 4 files to configure. 1. web.xml 2. pom.xml 3. applicationContext.xml 4.

Number input is string not integer in React : <p>I have a react component.

I was hoping to just have the one handleChange function for all my inputs as ill be adding some more, is this possible? </p>

Is it possible to discover and run third-party Android Instant Apps on an emulated device? : <p>I'm currently trying to learn about Android instant apps. Since I don't own any real devices that support them, I'm using the emulator (from Android Studio 3.0 Canary 9). I can successfully run "toy" instant apps (<a href="https://developer.android.com/topic/instant-apps/getting-started/first-instant-app.html" rel="noreferrer">like this</a>) on my emulated Nexus 5x (with Play Store), so I believe that my development environment is configured correctly.</p> <p>However, I was curious to learn about the discovery process for third-party apps, and find out what the user experience is like. Lacking a suitable device of my own, I used the emulated Chrome browser to search for sites (like Stack Exchange) that have instant apps enabled. But these searches only give me the usual websites (not instant apps).</p> <p>I read <a href="https://stackoverflow.com/questions/44250681/is-it-possible-to-use-published-instant-appsbuzzfeed-wish-etc-on-the-emulato">this post</a> with great interest, because it seems to suggest that this <em>should</em> work. However, those answers didn't seem to help me. </p> <ul> <li>I'm in Australia, which should be <a href="https://support.google.com/googleplay/android-developer/answer/7381861#production" rel="noreferrer">one of the countries where Instant Apps are supported</a>.</li> <li>As suggested in one answer, I've tried sending links that should open in instant apps in emails and then clicking on them, but it still just sends me to a browser link.</li> <li>The answer about DAL verification is interesting, but doesn't seem like it should apply when opening links in a browser?</li> </ul> <p>The API 24 and API 26 emulated devices (both of which include the Play Store) are currently in somewhat different conditions, probably because I've been trying all sorts of tricks to make it work. (TLDR: Nothing's working for me.)</p> <ul> <li><p>On the API 24 emulated device, if I type <code>adb shell pm list packages grep "com.google.android.instantapps.supervisor"</code> then it outputs <code>package:com.google.android.instantapps.supervisor</code> as one answer suggests (but it still doesn't work).</p></li> <li><p>The API 24 device has <code>Google Play services for Instant Apps (version 1.9-sdk-155682639)</code> installed.</p></li> <li><p>The API 24 device has a "lightning bolt" notification at the top of the screen saying "Development Mode Active": <code>URLs will be routed to Dev Manager in order to launch Instant Apps locally. Uninstall Dev Manager to disable Development Mode.</code></p></li> <li><p>On the API 24 device, Settings -> Google -> Instant Apps, instant apps is set to true</p></li> <li><p>On the API 26 emulated device, if I type <code>adb shell pm list packages grep "com.google.android.instantapps.supervisor"</code> returns nothing</p></li> <li><p>On the API 26 device, <code>Google Play services for Instant Apps</code> isn't installed, and there isn't any "lightning bolt" notification either</p></li> <li><p>On the API 26 device, Settings -> Google doesn't list Instant Apps (so there's nothing to set)</p></li> </ul> <p>Here are some additional details, in case they're relevant:</p> <ul> <li>My development machine runs Windows 10 <sub><sup>(not by choice)</sup></sub></li> <li>The emulated devices are Nexus 5x (API 24 and 26) with Play Store</li> <li>I also tried the "x86" images, since some people recommended them for Windows, but they didn't work either. (This may be because the "x86" images don't come with Play Store, which I think is required for Instant Apps?)</li> <li>I'm logged into a real Google user account on the emulated devices.</li> </ul> <p>With the development environment I've set up now, I can continue to develop my own instant app, deploy it on my own emulated devices, and test it. I was really just curious to see how other people's instant apps work. And another post (linked above) suggested that I should be able to do this.</p> <p>So here's my question: Is it possible to discover and open third-party Instant Apps on an emulated device (and if so, how)?</p>

Are Kotlin data types built off primitive or non-primitive Java data types? : <p>I am new to Kotlin and was playing around with the data types. I took an <code>Int</code> type and then tried to cast it as a <code>Double</code> by saying <code>num as Double</code>, a call that is valid in java (non syntactically but you get the point). However, this failed, saying that Int cannot be cast to Double. I am assuming this is because it is built off the Integer class rather than the raw int data type. Am I correct, and what is the most efficient way to cast values? There is a <code>.toDouble()</code> function, but this seems inefficient and unwieldy. </p>
