I'm trying to figure out how to create a timeout for the handshake process in a TLS connection in a QTcpServer.

I tried something like this in the overriden incomingConnection function:

Good day everyone, I am currently struggling with writing mysql query which should make chat group from messages. App which I am making is taking data from other service, so it's not up to me to also manage chat groups, I need take this info from messages themselves.

My table of messages looks like this:

My only input data which I sent from my mobile app is receiveAddr so I need to add this to group anything which containes address in either sentAddr or receiveAddr, here is representation of what I want to achieve

It needs to have latest text counted amount of 0 in read column and lastMessage which is time of last message

I came up with something which sort of works if the user of the mobile app would be just receiving messages, which would be this:

SELECT sentAddr, COUNT(IF(campus.messages.read = 0, 1, NULL)) as unread, max(receiveTime) as lastMessage, max(text) as text FROM campus.messages WHERE (SELECT max(receiveTime) FROM campus.messages) AND receiveAddr = 'CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF' GROUP BY sentAddr, receiveAddr

But sadly that does not get me a text from the latest message and not even taking into account that if the same user send some message, it shows as different group, which is not really helpful. I also came up with something which groups sendAddr and receiveAddr into one group no matter if it's on sending or receiving side:

GROUP BY CONCAT(LEAST(receiveAddr,sentAddr),' ', GREATEST(receiveAddr, sentAddr))

However in that case I can't with this added to upper query, it does not retrieve latest text, which is useless. So is there any chance of doing this with one query, no matter how long and convoluted it would be? And just to remind, only input data is user's address, which can be either sending or receiving address from the table. So is there any solution to this?

Version of the mysql database is 8.0.25

I get a weird problem when running my code, I had a perfectly running code, in order to improve it I coded a little obj file loader function (which seems to work fine even if, at the moment it is not impacting the end result of the code).

The problem is, in this function I use malloc() to create tables and, due to this, I need to free() the memory at the end of the function, this free(some_pointers) don't work and mess up the whole code. I need to tell you that I'm 100% sure this line is the one causing the problem because if I remove it everything work fine (but the memory is still allocated). To sum up, in a function:

*I allocate memory (double *x = malloc(sizeof(double)*integer);)

*I'm modifying this memory (until here everything work fine)

*I free the memory free(x); (adding this line cause the program to crash)

As asked here's the full code of my function:

Taking the following C code

My task is to copy JPEGs from a file the intend here is to find the JPEGs and create a new file to put it, all JPEGs are store back to back and the "identifier" is always in the beggining of a 512 BYTE block. my problem shows only in the first file where it writes 128 bytes before the expected data from the buffer rendering the new file useless.

what i have tried:

• Check the original file to see if the data came from it but it does not.
• Malloc all the pointers to have "clear memory".
• Reorganize the code.

any ideas?

I'm wondering if there is a better way to handle multiple matches on longer method calls than repeating the long call in a piped statement. Example:

I can't compile DPDK inside a docker container, running under WSL2 as VM (and windows 10 as the host machine).

Background

Trying to compile DPDK locally inside a wsl-container some DPDK lib that used to be built on remote native linux machines.

The Dockerfile running the compilation had installed kernel headers, GNU toolchain and other various dependencies. The distribution is CentOS7.

The containers are managed by Docker Desktop

Versions are useless information here.

The Problem

Similar problems across DPDK versions. In DPDK 20.11, using the meason build-system, the file kernel/linux/meason.build:

../kernel/linux/meson.build:23:1: ERROR: Problem encountered: Cannot compile kernel modules as requested - are kernel headers installed?

If I compile different DPDK versions of DPDK or building using other build-systems (makefiles), I am getting variants of the same error.

The aim is to use the class particle to create particles (upon the user clicking a button) and once that is running as it should be, to give the user some control over speed, gravity and some other things. The problem is that every time the user clicks to create a new particle, the speed increases.

I'm not sure why but when I demo it without having the requestanimationframe, it looks like it works as it should, but it's useless if it's not animated.

I have this strange problem where I loose data in a simple for loop.

Basically I have an interval, that I have to cut in smaller intervals finishing by a mark (here 5.0). The whole result is saved into an array of lists.

I use the switch index (which are the indexes of the number 5 that we can get easily with find comamnds for example) and hte number of blocks (smaller intervals at the end).

My algorithm works well because i print after each loop the smaller interval i extracted. however when passing to the next loop the previous interval gets put to an empty list. Why is this happening? At the end I have a useless array of empty lists.

I added WriteLine statements to show you the problem. Before one pass of a loop finishes i get my interval like i want to, but when passing to the next one, somehow the variable gets emptied
