PDO not working - simply displaying some of the code as if it wasn't PHP : <p>I'm new to PDO, so I apologise if this is a silly question. I have two files: writel.html contains a simple form, with formaction="submitArticle.php" and method="post". submitArticle.php contains the following:</p>
<pre><code><?php
$con = new PDO('mysql:host=localhost;dbname=mysql','root','root');
$submission = $con->prepare("
INSERT INTO sfWritings(title, summary, content)
VALUES(:title, :summary, :content)
");
$submission_execution = $submission->execute([
'title' => $_POST['title'],
'summary' => $_POST['summary'],
'content' => $_POST['content']
]);
if($submission_execution) {
echo "article submitted";
}
?>
</code></pre>
<p>However, instead of getting either the echo message, or some sort of error, I simply get the whole code, as if it doesn't realise it's PHP or something:
<a href="https://i.stack.imgur.com/UYVBR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/UYVBR.png" alt="Screenshot"></a></p>
<p>If I add some html tags (<code><html></code>, <code><body></code> etc.) then it starts giving me this:
<a href="https://i.stack.imgur.com/tLH8F.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tLH8F.png" alt="Screenshot when using html tags"></a></p>
<p>The database is ok (I've been able to fetch some test data from it). And the way I'm doing the insert closely follows a (working) example for a tutorial. So I''m a bit stuck for what I'm doing wrong!</p>

Python Datetime : use strftime() with a timezone-aware date : <p>Suppose I have date <code>d</code> like this : </p>
<pre><code>>>> d
datetime(2009, 4, 19, 21, 12, tzinfo=tzoffset(None, -7200))
</code></pre>
<p>As you can see, it is "timezone aware", there is an offset of 2 Hour, utctime is </p>
<pre><code>>>> d.utctimetuple()
time.struct_time(tm_year=2009, tm_mon=4, tm_mday=19,
tm_hour=23, tm_min=12, tm_sec=0,
tm_wday=6, tm_yday=109, tm_isdst=0)
</code></pre>
<p>So, real UTC date is 19th March 2009 <strong>23</strong>:12:00, right ? </p>
<p>Now I need to format my date in string, I use </p>
<pre><code>>>> d.strftime('%Y-%m-%d %H:%M:%S.%f')
'2009-04-19 21:12:00.000000'
</code></pre>
<p>Which doesn't seems to take this offset into account. How to fix that ? </p>

NumPy save some arrays at once : <p>I working on different shapes of arrays and I want to save them all with <code>numpy.save</code>, so, consider I have </p>
<pre><code>mat1 = numpy.arange(8).reshape(4, 2)
mat2 = numpy.arange(9).reshape(2, 3)
numpy.save('mat.npy', numpy.array([mat1, mat2]))
</code></pre>
<p>It works. But when I have two matrices with one dimension of same size it's not working. </p>
<pre><code>mat1 = numpy.arange(8).reshape(2, 4)
mat2 = numpy.arange(10).reshape(2, 5)
numpy.save('mat.npy', numpy.array([mat1, mat2]))
</code></pre>
<p>It causes<br>
<code>Traceback (most recent call last):
File "<input>", line 1, in <module>
ValueError: could not broadcast input array from shape (2,4) into shape (2)</code></p>
<p>And note that the problem caused by <code>numpy.array([mat1, mat2])</code> and not by <code>numpy.save</code></p>
<p>I know that such array is possible:</p>
<p><code>>> numpy.array([[[1, 2]], [[1, 2], [3, 4]]])
array([[[1, 2]], [[1, 2], [3, 4]]], dtype=object)</code></p>
<p>So, all of what I want is to save two arrays as <code>mat1</code> and <code>mat2</code> at once.</p>

how can I asynchronously map/filter an asynchronous iterable? : <p>Let's say I have an asynchronous iterable that I can pass over using <code>async for</code>, how then can I then map and filter it to a new asynchronous iterator? The following code which is an adaptation of how I'd do the same thing with a synchronous iterable doesn't work, since <code>yield</code> isn't allowed inside <code>async def</code>s.</p>
<pre><code>async def mapfilter(aiterable, p, func):
async for payload in aiterable:
if p(payload):
# This part isn't allowed, but hopefully it should be clear
# what I'm trying to accomplish.
yield func(payload)

Checking if user input matches a predefined pattern of words : <p>I want to make a grammar checker with Python. But this is not going to be a standard grammar checker. This is intended for learners of the English language who are at the beginner level. I wrote the following code to check if the user uses the correct form of the verb:</p>
<pre><code>preList = ['came', 'waited', 'sat', 'stood', 'went', 'left']
sentence = input("Type a sentence using the past simple tense: ")
sentence = sentence.split()
if sentence[1] or sentence[2] or sentence[3] in preList:
print("Looks good!")
else:
print("Maybe you're missing something!")
</code></pre>
<p>The problem I have is that even if the user input does not contain any of the words in preList, it prints "Looks good". What is the problem with my code?</p>

How do apps like Pizza Hut generate all nearby Pizza Hut locations using Google Maps? : <p>I am fairly new to programming and am currently working on my first full app by myself. The app has a few different parts, and one of those parts helps narrow a user's food selection down by restaurant. For instance, if the user decided they wanted to eat at Pizza Hut, my idea is that my app would generate a Google Map and using Google API, show the user all nearby pizza huts. I would also like the user to be able to click on the pizza hut icons and then it would direct them to Google Maps for directions.</p>
<p>Currently I am able to populate Google Maps, ask the user for permission to find their location, as well as I implemented Google Place Picker. The Google Place Picker works a bit differently than I first imagined though.</p>
<p>What I'm stuck on is how do I actually get just the Pizza Hut locations to populate as opposed to everything else as well?</p>
<p>Thank you!</p>

iOS 10 UNUserNotificationCenterDelegate not called. push notifications not working : <p>Tearing my hair out tying to get push notifications to work in iOS10. Current setup:</p>

let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
if error == nil {
print("DID REQUEST THE NOTIFICATION")
UIApplication.shared.registerForRemoteNotifications()
}

print("DID SET DELEGATE")

<pre><code>print("DID REGISTER FOR A REMOTE NOTIFICATION AND THE TOKEN IS \(deviceToken.base64EncodedString())"
let request = UpdatePushNotificationSubscription_Request(deviceToken: deviceToken)
updatePushNotificationSubscriptionWorker.updateSubscription(request)
</code></pre>
<p>I have checked the token is uploaded to the backend correctly and it does indeed match.</p>
<p>I have also implemented:</p>
<pre><code> @available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
print("GOT A NOTIFICATION")

@available(iOS 10.0, *)

//This is for the user tapping on the notification
print("GOT A NOTIFICATION")

<p>Now when I try to send a message from the backend the device just receives nothing. Delegates are not being called. Have no idea what I'm doing wrong here. Push is working for iOS9 and android devices. Any pointers to what I might be doing wrong?</p>

<pre><code>instance Arbitrary ProtocolPacket where
arbitrary = do
packetID <- choose (0x00,...) :: Gen Word8
case packetID of
0x00 -> do
a <- arbitrary
b <- arbitrary
c <- arbitrary
return $ Packet1 a b c
0x01 -> do
a <- arbitrary
return $ Packet2 a
0x02 -> do
a <- arbitrary
b <- arbitrary
c <- arbitrary
d <- arbitrary
e <- arbitrary
return $ Packet3 a b c d e
0x03 -> do
a <- arbitrary
b <- arbitrary
c <- arbitrary
d <- arbitrary
e <- arbitrary
f <- arbitrary
g <- arbitrary
return $ Packet4 a b c d e f g
...
</code></pre>
<p>Assume that I've gone ahead and defined <code>Arbitrary</code> for all relevant data constructor arguments that don't have <code>Arbitrary</code> defined out of the box, such code needs to be hand-written by me in order for the packet fields to be populated with meaningful data. But that's it.</p>
<p>But as you can see, I'm repeating myself <em>a lot</em> for something that is just grunt work. And this is a small sample of what I'm actually dealing with. Ideally, I would like to be able to just do this:</p>
<pre><code>{-# LANGUAGE DeriveGeneric #-}
import GHC.Generics
data ProtocolPacket
= Packet1 Word8 Text Int8
| Packet2 Text
| Packet3 Int Text Text Text Text
| Packet4 Int Double Double Double Int16 Int16 Int16
...
deriving (Show,Eq,Generic)
instance Arbitrary ProtocolPacket
</code></pre>
<p>like I can do with <code>FromJSON</code> and <code>ToJSON</code>, but this doesn't work. Is there there a method that does?</p>

when to go for new string instead of string literal in java : <p>I know when we use <code>String s = new String("abc");</code> JVM will create the object in heap and when we use <code>String s = "abc";</code> the object gets created in String constant pool.</p>
<p>IMO, using <code>String s = "abc";</code> serves our purpose. In which case we have to go for <code>new String("abc");</code></p>

Date and Time formatting on python : I'm trying to get make a comments section for a website with the backend written in python. As of now, everything works fine except I cannot figure out how to format the date and time the way I want.
What I am trying to have at the time of posting is either of these:
1) Posted on Tue, 06/12/18 at - 11:20
or
2) Posted on 06/12/18 at - 11:21
Currently, what I have when the method is called is this:
import time
from datetime import *
time = "Posted on " + str(datetime.now().day) + "/" + str(datetime.now().month)
+ " at: " + str(datetime.now().hour) + ":" + str(datetime.now().minute)

clang-format closing bracket on a new line : <p>I have code that looks like this:</p>
<pre><code>EXPECT_EQ(
subsystem->previousTouchscreenState,
expectedTouchscreenState

</code></pre>
<p>When I run <code>clang-format</code>, it reformats the snippet to look like this:</p>
<pre><code>EXPECT_EQ(
subsystem->previousTouchscreenState,
expectedTouchscreenState );
</code></pre>
<p>This is quite counterintuitive; I'd like my multi-line function invocations (although <code>EXPECT_EQ</code> is a macro in this case) to have the closing round bracket on its own line, indented to the level of the name of the function, as it is in the first snippet.</p>
<p>How do I accomplish this with <code>clang-format</code>?</p>
<p>Many thanks.</p>

Which would be more correct on C++11: switch-case or if( .. || .. || .. )? : I'm trying to build simple lexical analyzer - lexer. The part I'm working on now is tokenizer. I'm writing function which determines whitespaces (whitespaces, tabs, newlines(CR, LF)) in the input sequence. So the question is which code is more correct:
The code with switch-case statement:
bool isWhitespace(wchar_t &symbol) {
switch (symbol) {
case L' ':
case L'\t':
case L'\r':
case L'\n':
return true;
default:
return false;
}
}
Or the code with if(.. || .. || ..) statement:
bool isWhitespace(wchar_t &symbol) {
if (symbol == L' ' ||
symbol == L'\t' ||
symbol == L'\r' ||
symbol == L'\n') {
return true;
}
return false;
}
And which one would be faster?

What is the advantage of internal only elbs over secured public elbs? : <p>I'm a little unclear on the advantage of internal only ELBs. I could restrict access to my public ELBs with security groups and I have the advantage of allowing public traffic by merely adjusting the security group.</p>
<p>Is the advantage just being absolutely sure no public traffic can hit the ELB? Is it purely for that fail safe kind of thing or is there something here I am missing that I can do with internal ELB but not external ELB?</p>

How to perform multiplication for integers larger than 64 bits in C? : I want to multiply 57bit integer with 11bit integer. The result can be up to 68bits so I'm planning to split my result in to 2 different integers.

There is some ways to that online but all of them are not meet my criteria. I want to split the result as 60bits lower part and 8 bits higher part.

Speeding up package load in Julia : <p>I wrote a program to solve a linear program in Julia using GLPKMathProgInterface and JuMP. The Julia code is being called by python program which runs multiple instances of the Juila code through multiple command line calls. While I'm extremely happy with the performance of the actual solver the initialization is extremely slow. I was wondering if there were approaches to speed this up. </p>
<p>For example if I just save the following to a file </p>
<pre><code>@time using DataFrames, CSV, GLPKMathProgInterface, JuMP, ArgParse
</code></pre>
<p>and run it</p>
<pre><code>mylabtop:~ me$ julia test.jl
12.270137 seconds (6.54 M allocations: 364.537 MiB, 3.05% gc time)
</code></pre>
<p>This seems extremely slow, is there some good way to speed up using modules like a precompile step I could do once? </p>

how to solve these nin javascript : Locate the displayBirthdate function you initially defined, which took no parameter. Modify it to use object de-structuring to get just the 'dob' property of the parameter object it will receive
here's the code
const displayBirthdate = () => {
};
const displayExtraUserInfo = (extra) => {
document.getElementById("btn-birthdate").addEventListener("click", ()=> {
displayBirthdate(extra)
})
"dob": {
"date": "1986-02-19T23:25:07Z",
"age": 33
}
const getUser = () => ({
date: 156-888,

Does std::vector::reserve guarantee that the implementation will not invalidate iterators in this case? : <p>Here is a function which intends to:</p>
<p>a) accept a vector of int</p>
<p>b) for each int in the input vector, append the inverse of this int</p>
<p>preconditions: none</p>
<p>postconditions: returned vector's size() is exacly 2 * the input vector's size.</p>
<p>Note that the vector is modified in-place.</p>
<h2>Question:</h2>
<p>Is this function strictly defined behaviour vis-a-vis iterator invalidation during the transform?</p>
<h2>Bonus:</h2>
<p>Is there a better/more succinct/robust way to write it?</p>
<h2>Code:</h2>
<pre><code>std::vector<int> append_negatives(std::vector<int> v)

v.reserve(v.size() * 2);
std::transform(begin(v), end(v),

How to change the size of item-avatar in ionic? : <p>I am developing an app using ionic framework. I need to display an image in the side menu header. I have used <strong>item-avatar</strong> to display the image. Here is the code.</p>
<pre><code><ion-side-menus>
<ion-side-menu side="left">
<ion-header-bar class="bar-calm style="height:200px" >
<div class="list" >
<a class="item item-avatar">
<img src="some image source">
<p>This is an image</p>
</a>
</div>
</ion-header-bar>
</ion-side-menu>
<ion-side-menu-content>
<ion-list >
<!-- Links to the pages that must contain the side menu. -->
<ion-item href="#/side-menu24/page1">Page1</ion-item>
<ion-item href="#/side-menu24/page2"> Page2</ion-item>
</ion-list>
</ion-side-menu-content>
</code></pre>
<p></p>
<p>How do I change(increase) the size of the image displayed in the item-avatar? I was suggested the following CSS:</p>
<pre><code>.list .item-avatar{
width: 20px !important;
height : 60px !important;}
</code></pre>
<p>This increases the content size(size allocated to the div tag) of the item-avatar as a whole but the image size remains the same. Is there any way to increase the size of the image displayed inside the item-avatar?</p>

Horizontal Scroll using buttons on angular2 : <p>So I have this app in angular2 where I need to scroll a component horizontally but with buttons right and left. So I need a function for each button that scroll to right or left the content. I need something like this:
<a href="https://i.stack.imgur.com/eJaau.png" rel="noreferrer"><img src="https://i.stack.imgur.com/eJaau.png" alt="enter image description here"></a></p>
<p>I tried using <code>document.getElementById('myscrolldiv').animate({ scrollLeft: "-=" + 250 + "px"; }</code> but Angular does not recognize the <code>animate</code> line.</p>
<p>So I am looking for a diferent way of scroll horizontally using buttons but NOT using jquery. Is there any way to do this in angular?</p>
<p>Here is my html</p>
<pre><code><div class="container">
<div class="side">
<mat-icon (click)="scrollLeft()">keyboard_arrow_left</mat-icon>
</div>
<div id="widgetsContent" class="middle">
<div class="scrolls">
<div class="info-widget">
WIDGET
</div>
<div class="info-widget">

</div>
<div class="info-widget">

<div class="info-widget">

<div class="info-widget">

</div>
</div>
</div>
<div class="side">
<mat-icon (click)="scrollRight()">keyboard_arrow_right</mat-icon>
</div>
</div>
</code></pre>
<p>And here is my css</p>
<pre><code>.container {
display: flex;
height: 22.5vh !important;
}
.side {
width: 50px;
height: 22.5vh !important;
}
.middle {
flex-grow: 1;
height: 22.5vh !important;
overflow-x: scroll;
overflow-y: hidden;
white-space: nowrap;
}
</code></pre>
<p>So, how do I scroll right and left pushing the buttons? please help.</p>

MATLAB no longer unloading MEX-files after upgrade to macOS Mojave : <p>In MATLAB, <code>clear mex</code> unloads all MEX-files from memory (unless they're locked). Under previous versions of macOS, I was able to re-compile a MEX-file and run the modified version without restarting MATLAB, simply by issuing a <code>clear mex</code> command. This is no longer possible under Mojave.</p>
<p>For example, take this trivial MEX-file (<code>get_data_pointer.c</code>):</p>
<pre class="lang-c prettyprint-override"><code>#include "mex.h"
void mexFunction( int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[] )
{
plhs[0] = mxCreateNumericMatrix(1, 1, mxUINT64_CLASS, mxREAL);
*(uint64_t*)mxGetData(plhs[0]) = (uint64_t)mxGetData(prhs[0]);
}
</code></pre>
<p>We can create the MEX-file and load it in memory with</p>
<pre class="lang-matlab prettyprint-override"><code>mex get_data_pointer.c
get_data_pointer(0)
</code></pre>
<p>To clear it,</p>
<pre class="lang-matlab prettyprint-override"><code>clear mex
[~,mexfiles] = inmem
version -modules
</code></pre>
<p><code>inmem</code> indeed returns an empty cell array indicating no MEX-files are loaded in memory, But <code>version -modules</code> (undocumented, from <a href="https://stackoverflow.com/a/20407568/7328782">this answer</a>) still shows <code>/Users/cris/matlab/get_data_pointer.mexmaci64</code> in its output. And changing the MEX-file source code and re-compiling demonstrates that, indeed, the MEX-file is never reloaded, the old version is still being run until one exits MATLAB.</p>
<p>I am seeing this on MATLAB R2017a on macOS Mojave. This was never a problem with the same MATLAB version under High Sierra.</p>
<p>How can I force MATLAB to unload the MEX-file without restarting?</p>

Vue instance inside Vue instance : <p>Sup people!</p>
<p>I got this HTML code here:</p>
<pre><code>// index.html
<div data-init="component-one">
<...>
<div data-init="component-two">
<button @click="doSomething($event)">
</div>
</div>
</code></pre>
<p>This basically references a Vue instance inside another Vue instance if I understood everything correctly. The respective JS code is split up in two files and looks like this:</p>
<pre><code>// componentOne.js
new Vue(
el: '[data-init="component-one"]',
data: {...},
methods: {...}
);
// componentTwo.js
new Vue(
el: '[data-init="component-two"]'
data: {...}
methods: {
doSomething: function(event) {...}
}
);
</code></pre>
<p>Now, the problem with this is, that <code>doSomething</code> from <code>componentTwo</code> never gets called.</p>
<p>But when I do some inline stuff, like <code>{{ 3 + 3 }}</code>, it gets computed like it should. So Vue knows there is something. And it also removes the <code>@click</code> element on page load.</p>
<p>I tried fiddling around with <code>inline-template</code> as well, but it doesn't really work as I'd expect it to in this situation. And I figured it isn't meant for this case anyway, so I dropped it again.</p>
<p>What would the correct approach be here? And how can I make this work the easiest way possible with how it's set up right now?</p>
<p>The Vue version we use is <code>2.1.8</code>.</p>
<p>Cheers!</p>

Why is Python 3 http.client so much faster than python-requests? : <p>I was testing different Python HTTP libraries today and I realized that <a href="https://docs.python.org/3/library/http.client.html" rel="noreferrer"><code>http.client</code></a> library seems to perform much much faster than <a href="http://docs.python-requests.org/en/master/" rel="noreferrer"><code>requests</code></a>. </p>
<p>To test it you can run following two code samples.</p>
<pre><code>import http.client
conn = http.client.HTTPConnection("localhost", port=8000)
for i in range(1000):
conn.request("GET", "/")
r1 = conn.getresponse()
body = r1.read()
print(r1.status)
conn.close()
</code></pre>
<p>and here is code doing same thing with python-requests:</p>
<pre><code>import requests
with requests.Session() as session:
for i in range(1000):
r = session.get("http://localhost:8000")
print(r.status_code)
</code></pre>
<p>If I start SimpleHTTPServer:</p>
<pre><code>> python -m http.server
</code></pre>
<p>and run above code samples (I'm using Python 3.5.2). I get following results:</p>
<p>http.client:</p>
<pre><code>0.35user 0.10system 0:00.71elapsed 64%CPU
</code></pre>
<p>python-requests:</p>
<pre><code>1.76user 0.10system 0:02.17elapsed 85%CPU
</code></pre>
<p>Are my measurements and tests correct? Can you reproduce them too? If yes does anyone know what's going on inside <code>http.client</code> that make it so much faster? Why is there such big difference in processing time?</p>

R: find date closest to row specific date : I have the following dataframe in R

2nd column contains reference date per identification number (cdatalg)
3rd through 16th column contains dates (datesc1:datesc14)
I wish to enter a 17th column in which the date in column 3:16 is printed which is closest to the reference date in column 2.
I have tried combinations of apply and which.min and neardate, though can't figure it out.
A push in the right direction would be very much appreciated.

After Task.IsCompleted what is better: await or Result : <p>I'm working in a simple timeout code for my http requests. I got this</p>
<pre><code>private async Task<HttpResponseMessage> ExecuteIOTask(Task<HttpResponseMessage> ioTask, int timeout)
{
var timeoutTask = await Task.WhenAny(Task.Delay(timeout), ioTask);
if (ioTask.IsCompleted)
return ioTask.Result;
throw new TimeoutException();
}
</code></pre>
<p>After IsCompleted, is there any difference using <code>Result</code> vs <code>await</code> ? The task is already completed at that instance, so I think the performance should be the same. But i'm a little concern about the exception handling. I think <code>Result</code> is not going to propagate the exceptions but <code>await</code> will.</p>
<p>Is this correct?</p>
