Lesson of the Month

Sometimes you may feel like you're behind compared to your friends or the people around you. But remember God has His own perfect timing.

There will be seasons when you feel discouraged, when it seems like you're losing opportunities or not accomplishing what you hoped. That doesn't mean God has forgotten you. He knows exactly what you need, and He will provide it at the right time.

While you wait, don't lose your faith. Everything else can be regained, but don't lose him. You can't afford that. And just wait doing all what you have to do

Trust His timing. Stay faithful. 🤍

The moment you start measuring your chapter 3 against someone else's chapter 20, you've already lost the plot of your own story. You don't know how many drafts their story went through. You don't see the deleted scenes. You're just seeing the page they chose to show you.
God isn't editing everyone's book on the same deadline. He's a better author than that.
Stay in your chapter. It's going somewhere. But I still say this having my own doubts but let God help my disbelief.
And if I'm being honest -> this is as much a note to myself as it is to anyone reading. We're all finding our way through this together, by His grace.

so today i was studying C and implementing string helper functions using pointers. my strcat looked like this:

void strcat(char *s, char *t) {
    while(*s != '\0') s++;
    while(*s++ = *t++ != '\0');
}

(the bug here is actually operator precedence — != runs before = but that's not the point of this post lol)
so i asked GPT why my code was wrong, it fixed it, then casually added at the bottom: "also you shouldn't do printf(pms) directly — use printf("%s", pms) instead"
i almost ignored it. glad i didn't.

turns out printf() isn't just a printing function -> it's a parsing engine. when you pass it a string it actively scans for % symbols and treats them as instructions. %x means "pull a hex value off the stack." %n means "write to a memory address on the stack."
so if a user somehow controls what's inside pms and injects %x %x %x %x ... printf just walks your stack and prints whatever it finds there. passwords. keys. memory addresses. you didn't print a string -> you handed them a live window into your program's memory.
and with %n? they're not reading anymore. they're writing. overwriting variables, corrupting return addresses, executing arbitrary code.
the fix is literally one extra argument:

printf("%s", pms);

And this is called the format string attack

and u know my code even had another vulnerability which is buffer overflow -> it is a common problem in a lot of places where u allow someone to read memory space they are not allowed to ... so mycode assumes that s has enough space to copy the string t, but if t is large always incrementing the pointer s will yield in reading in a memory space outside our reach which would cause one of two things: 1 -> segmentation fault or 2 -> that someone has access to unintended memory address, where for eg credentials could have been stored

Guys check this : https://aws.amazon.com/events/reinvent/experiences/all-builders-welcome/

So now thought to text model out here 🔥 ... it just reads ur brain activity, just as simple as that ...

The AI looks at the raw brainwaves and guesses the letters you are thinking of (e.g., “h-o-w-a-r-e-y-o-u”).

It is really insane the time we live in - it is very relevant for those who lost their speech due to stroke and other causes
