56,277,058 | Handle multiple events in gpio | <p>I'm new to embedded programming and I apologise in advance for any confusion.</p>
<p>I need to handle multiple events from different devices connected to a gpio. These events need to be monitored continually. This means that after one event is generated and handled, the code needs to keep monitoring the device for other events.</p>
<p>I understand the concept of interruptions and polling in Linux (the kernel gets an interruption and dispatch it to the handler which goes on up to the callee of an epoll which is inside an infinite loop while(1)-like). </p>
<p>This is fine for one-time, single-event toy models. In a embedded system with limited resources such as the <a href="https://www.digikey.com/eewiki/display/linuxonarm/AT91SAM9x5#AT91SAM9x5-LinuxKernel" rel="nofollow noreferrer">AT91SAM9x5</a> that runs at 400mhz and has 128mb of ram what can I do ? I believe that the while(1)-like pattern isn't the best choice. I've heard good things about thread pool solution but at the heart of each thread don't we find a while(1) ? </p>
<p>What are my options to attack this problem ?</p>

56,278,371 | GCC 9.1 returns void& as result type for an explicit destructor call. Is this a bug? | <p>I'm trying to get <a href="https://stackoverflow.com/a/10722840/4694124">this is-class-defined-check</a> to work, which relies on the fact that <code>decltype(std::declval<Foo>().~Foo())</code> is <code>void</code> if <code>Foo</code> has a destructor (which it has if it is definedβ¦) and is ill-formed otherwise, invoking SFINAE in this case.</p>
<p>However, I can't get the code to work with GCC 9.1, and that is because GCC 9.1 seems to consider that type to be <code>void &</code> <em>if the destructor is defaulted</em>, consider this example:</p>
<pre><code>#include <type_traits>
class Foo {
public:
// With this, the DestructorReturnType below becomes "void"
// ~Foo () {}
};
// β¦ unless I specify the user-defined destructor above, in which case it is "void"
using DestructorReturnType = decltype(std::declval<Foo>().~Foo());
template<class T>
class TD;
// Says: aggregate 'TD<void&> t' has incomplete type and cannot be defined
TD<DestructorReturnType> t;
</code></pre>
<p>(available at <a href="https://gcc.godbolt.org/z/K1TjOP" rel="noreferrer">https://gcc.godbolt.org/z/K1TjOP</a> ) </p>
<p>If I user-define an empty destructor, the type jumps back to <code>void</code>. Also if I switch back to GCC 8.x.</p>
<p>The C++17 standard states in [expr.call]:</p>
<blockquote>
<p>If the postfix-expression designates a destructor, the type of the function call expression is void; [β¦]</p>
</blockquote>
<p>Because of all this, I suspect that GCC 8.x (and clang, β¦) are correct, and GCC 9.1 is just wrong. Or am I missing something?</p>

56,279,671 | What happend when we override union fields in C? | I am reading the implementation of Thompson algorithm for matching regular expression in C. [link][1]. I saw this snippet of code
```C
/*
* Since the out pointers in the list are always
* uninitialized, we use the pointers themselves
* as storage for the Ptrlists.
*/
union Ptrlist
{
Ptrlist *next;
State *s;
};
/* Create singleton list containing just outp. */
Ptrlist*
list1(State **outp)
{
Ptrlist *l;
l = (Ptrlist*)outp;
l->next = NULL;
return l;
}
```
But as I understand, in `union` type, all fields share the same memory. So why can we set `l->next=NULL` after casting `l=(Ptrlist*)outp;` because by doing that, we that that memory location to `NULL` and `l` will become `NULL`?

56,294,961 | Robolectric fails on command line but succeeds in Android Studio | <p>I have a test where I use Robolectric which succeeds in Android Studio, but does not on the command line.</p>
<p>I use Robolectric 4.2 and the test involves a cipher which I partially mock for this test.</p>
<pre><code>//How the cipher is created
val mockCipher = object : Cipher(MockCipherSpi(), null, null) {}
</code></pre>
<p>The MockCipher basically just returns the unencrypted input:</p>
<pre><code>class MockCipherSpi : CipherSpi() {
...
private val algorithmParametersSpi: AlgorithmParametersSpi? = object : AlgorithmParametersSpi() {
...
override fun <T : AlgorithmParameterSpec?> engineGetParameterSpec(paramSpec: Class<T>?): T {
return IvParameterSpec(byteArrayOf()) as T
}
}
...
override fun engineGetParameters(): AlgorithmParameters {
return object : AlgorithmParameters(algorithmParametersSpi, null, null) {
init {
init(byteArrayOf())
}
}
}
}
</code></pre>
<p>The reason my test fails is that I get a null pointer exception when I try to get the IV from the cipher:</p>
<pre><code>cipher.parameters.getParameterSpec(IvParameterSpec::class.java).iv
</code></pre>
<p>This works perfectly fine for Android Studio and I can even debug it, but running it from the command line with <code>./gradlew test</code> this fails.</p>
<pre><code>java.lang.NullPointerException
at javax.crypto.Cipher.<init>(Cipher.java:268)
at the place where I try to access the iv

In the interests of simplicity Iβve reproduced it using this basic playbook for a single node Drupal server. <a href="https://github.com/geerlingguy/ansible-for-devops/tree/master/drupal" rel="noreferrer">https://github.com/geerlingguy/ansible-for-devops/tree/master/drupal</a>; this playbook works fine on earlier versions of ubuntu, but not on 18.04 which I understand includes python3 by default.</p>
<p>Iβve used vagrant to create the base machine, which shows the following:</p>
<pre><code>$ which python

$ which python2
/usr/bin/python2
$ which python3

$ python2 --version
Python 2.7.15rc1
$ python3 --version
Python 3.6.7

<p>Which seems to be telling me that both python 2 and python 3 are installed, but that 2.7 is the default as that is what responds to $ python --version. </p>

56,326,097 | How to use backgroundworker with main thread functions? | I have some functions in my main thread, and I want to use them in the BackGroundWorker, the problem is that I can't reach to text boxes. I've seen many solutions but non of them worked.
I've tried to implement some functions I've seen on web, unfortunately due to my newbie skills, can't apply them..

56,329,093 | Memory leaks when using pandas_udf and Parquet serialization? | <p>I am currently developing my first whole system using PySpark and I am running into some strange, memory-related issues. In one of the stages, I would like to resemble a Split-Apply-Combine strategy in order to modify a DataFrame. That is, I would like to apply a function to each of the groups defined by a given column and finally combine them all. Problem is, the function I want to apply is a prediction method for a fitted model that "speaks" the Pandas idiom, i.e., it is vectorized and takes a Pandas Series as an input. </p>
<p>I have then designed an iterative strategy, traversing the groups and manually applying a pandas_udf.Scalar in order to solve the problem. The combination part is done using incremental calls to DataFrame.unionByName(). I have decided not to use the GroupedMap type of pandas_udf because the docs state that the memory should be managed by the user, and you should have special care whenever one of the groups might be too large to keep it in memory or be represented by a Pandas DataFrame.</p>
<p>The main problem is that all the processing seems to run fine, but in the end I want to serialize the final DataFrame to a Parquet file. And it is at this point where I receive a lot of Java-like errors about DataFrameWriter, or out-of-memory exceptions.</p>
<p>I have tried the code in both Windows and Linux machines. The only way I have managed to avoid the errors has been to increase the --driver-memory value in the machines. The minimum value is different in every platform, and is dependent on the size of the problem, which somehow makes me suspect on memory leaks.</p>
<p>The problem did not happen until I started using pandas_udf. I think that there is probably a memory leak somewhere in the whole process of pyarrow serialization taking place under the hood when using a pandas_udf.</p>
<p>I have created a minimal reproducible example. If I run this script directly using Python, it produces the error. Using spark-submit and increasing a lot the driver memory, it is possible to make it work. </p>
<pre class="lang-py prettyprint-override"><code>import pyspark

<p>Shockingly (at least for me), the problem seems to vanish if I put a call to repartition() just before the serialization statement.</p>

result.write.mode("overwrite").parquet(out_path)

<p>Having put this line into place, I can lower a lot the driver memory configuration, and the script runs fine. I can barely understand the relationship among all those factors, although I suspect lazy evaluation of the code and pyarrow serialization might be related.</p>

56,336,101 | Mongo DB - difference between standalone & 1-node replica set | <p>I needed to use Mongo DB transactions, and recently I understood that transactions don't work for Mongo standalone mode, but only for replica sets
(<a href="https://stackoverflow.com/questions/56322333/mongo-db-with-c-sharp-document-added-regardless-of-transaction/56323934#56323934">Mongo DB with C# - document added regardless of transaction</a>).<br>
Also, I read that standalone mode is not recommended for production.</p>
<p>So I found out that simply defining a replica set name in the mongod.cfg is enough to run Mongo DB as a replica set instead of standalone.<br>
After changing that, Mongo transactions started working.<br>
However, it feels a bit strange using it as replica-set although I'm not really using the replication functionality, and I want to make sure I'm using a valid configuration.</p>
<p>So my questions are:</p>
<ol>
<li>Is there any problem/disadvantage with running Mongo as a 1-node replica set, assuming I don't really need the replication, load balancing or any other scalable functionality? (as said I need it to allow transactions)</li>
<li>What are the functionality and performance differences, if any, between running as standalone vs. running as a 1-node replica set?</li>
<li>I've read that standalone mode is not recommended for production, although it sounds like it's the most basic configuration. I understand that this configuration is not used in most scenarios, but sometimes you may want to use it as a standard DB on a local machine. So why is standalone mode not recommended? Is it not stable enough, or other reasons?</li>

56,351,072 | How do i alter my Current code to read directly from the IDR register | <p>Modify the code for <strong>ReadJoystick()</strong> to read the <strong>IDR register</strong> directly for the ports associated
with the joystick inputs. The aim is to minimise the number of reads to the register. The code in
the template makes an individual call for each of the inputs pins, even though some of the pins are
on the same ports.
You can refer to the HAL code for inspiration. Use the defined values in the HAL for addressing
registers rather than creating new ones.</p>
<p>Example Code Given to Me</p>
<pre><code>GPIO_PinState HAL_GPIO_ReadPin(GPIO_TypeDef* GPIOx, uint16_t GPIO_Pin)
{
GPIO_PinState bitstatus;
/* Check the parameters */
assert_param(IS_GPIO_PIN(GPIO_Pin));
if ((GPIOx->IDR & GPIO_Pin) != (uint32_t)GPIO_PIN_RESET)
{
bitstatus = GPIO_PIN_SET;
}
else
{
bitstatus = GPIO_PIN_RESET;
}
return bitstatus;
</code></pre>
<p>}</p>
<hr>
<p><strong>Code I require to Alter</strong></p>
<p>// REPLACE THE FOLLOW CODE WITH YOUR SOLUTION </p>
<pre><code>uint8_t
ReadJoystick ()
{
uint8_t JoystickPosition = 0;
// Get current joystick value
if (HAL_GPIO_ReadPin (JOY_A_GPIO_Port, JOY_A_Pin) == GPIO_PIN_RESET)
{
JoystickPosition = 'L';
}
else if (HAL_GPIO_ReadPin (JOY_B_GPIO_Port, JOY_B_Pin) ==
GPIO_PIN_RESET)
{
JoystickPosition = 'U';
}
else if (HAL_GPIO_ReadPin (JOY_C_GPIO_Port, JOY_C_Pin) ==
GPIO_PIN_RESET)
{
JoystickPosition = 'D';
}
else if (HAL_GPIO_ReadPin (JOY_D_GPIO_Port, JOY_D_Pin) ==
GPIO_PIN_RESET)
{
JoystickPosition = 'R';
}
else if (HAL_GPIO_ReadPin (JOY_CTR_GPIO_Port, JOY_CTR_Pin) ==

{
JoystickPosition = 'C';
}
return JoystickPosition;

56,355,959 | Add/remove class to element with delay if mouse is still over | I am opening my submenu with adding a class("reveal") to it's parent. What i want to achieve is when i hover over a parent, if no "active" hover is going on, to open the submenu immediately, but if a submenu is already shown, then wait 1second before it opens a new one.
I want this because of "bad" mouse movement for it to wait in case the mouse leaves the submenu/parent to see if it re-enters in 1second.
I know there are a bunch of similar threads, but i already did my attempt and can't se eright now what im doing wrong:
$('.menu > li').hover(function(){
var ele = $(this);
if($('.menu li.reveal').length > 0){
var t = setTimeout(function(){
if( ele.hover() ){
$('.menu li.reveal').removeClass('reveal');
ele.addClass('reveal');
}
},1000);
}
else{
ele.addClass('reveal');
}
