Yeah no one perfect in programming but we attain excellence
that reminds me fullstack developers:

Hello Guys,
I need recommendations on learning Cpp...
I am C developer with around 6 years work experience. I learnt C programming deeply with understanding of how my code works upto instruction level handling and memory level handling.
Its been few years i didnt do coding work due to my task of team and project management. I want to refresh my c and upgrade to Cpp.. Could you recommend me resources or books which help me learn Object oriented programming in Cpp which can help me to learn deeply as i have learned C programming..

I hope my recommendation seeking question is clear... To be more specific, i dont want to learn syntax or using different features of cpp standards..
I'm more interested to know memory level handling of objects in runtime. For example, usage of vtables to determine function execution, clearly an internal concept..
Thanks.😊

Anyone here know about udp?
I want send data on udp protocol with esp32 module
But udp maximum packet size is 1460 and
I should be send data 30megabit per seconds
How should I do this?
Dima
Dima
send my parts
Dima
Try to parallel and synchronize
Anonymous
Split your data
I know that I must split data
But I want to achieve 30megabit per seconds speed
And when splitting data, esp32 need more time to send data.
Because it should be end current packet and begin new packet to send data

Based on my crude understanding of networks, UDP and large packets should allow for highest throughput. If you think you should be getting higher rates, try looking into your code and how you're sending your data to the esp32.

Use checkpoints/offsets to align data later
Can you explain more to me?
I have no information about it

And increasing upd packet size in esp32 is impossible
Dima

Add info in your packet header such as start and offset of data in a packet
When someone receives it will stick together
Dima
You can take look in idTech 3 source code

It means I begin one packet and send all data and end it in programming?

hey guy, pls help me a minor question. How can i save or share some post in telegram channel to some Note taking application such that Evernote or Apple Note in automaticaly way. (i don't way copy/paste repetitive). I've try to search to some IFFFT applets but not find anything.
(pls don't remove my post if content is not suitable cuz i think many newbie also has same question)

void test_lower_bound() {
vector<string> vs{"ABCDEFG", "BDFGACL", "CBAD"};
for (auto &s : vs) {
char c = 'B';
int p = lower_bound(s.begin(), s.end(), c) - s.begin();
cout << s << ", " << c << ": " << p << endl;
}
}
Why are the outputs for p are "1, 0, 3" rather than "1, 0, 0"?

std::lower_bound can be called only on sorted sequences
Otherwise the result is undefined

hey guys , how can I write a exploitable ouf bounds read / write proof of concept bug , and integer overflow for win32 spefic?
NXiss7
Why win32 specific?
When you overflow buffer, it overflows.
You mean syscalls
professor
Why win32? because target is windows , so i need to make it those on windows
professor
Malloc was replaced by heapcreate
NXiss7
Nope, you can use malloc.
Malloc just wraps heapcreate on Windows.

What would it be an example of out of bounds read / oob write
NXiss7
What would it be an example of out of bounds read / oob write
I have many, but the idea is:
char buf[] = "Okay";
char big_str[] = "This will overflow hard!!!!!"
memcpy(buf, big_str, sizeof(big_str));
Boom, you've overwritten many bytes....
But many compilers add stack protectors to protect important data a little more, keep that in mind.
professor
I mean the out of bounds
NXiss7
memcpy, malloc etc. are part of C standard and available everywhere btw.
HeapAlloc is Windows specific, you can use it obly on Windows but has it's own pros of course.
NXiss7
I mean the out of bounds
Dude, buf there has sizd of 5, when you read 6th "item" that's called out-of-bounds.
Hubert
I mean the out of bounds
you can set an uint32 variable out of range and change compiler option for overflow from warning to error level, because normally compiler will do implicit type casting
