ik

i did some stego

steganography?

ye

stegno is like creativity and knoledge

it nice

you find out that everything you have done is unsafe after one month

ctfs?

cts are nice

Capture the flag competitions Basically Capture the Flag (CTF) is a special kind of information security competitions. There are three common types of CTFs: Jeopardy, Attack-Defence and mixed. Jeopardy-style CTFs has a couple of questions (tasks) in range of categories. For example, Web, Forensic, Crypto, Binary or something else. Team can gain some points for every solved task. More points for more complicated tasks usually. The next task in chain can be opened only after some team solve previous task. Then the game time is over sum of points shows you a CTF winer. Famous example of such CTF is Defcon CTF quals. Well, attack-defence is another interesting kind of competitions. Here every team has own network(or only one host) with vulnarable services. Your team has time for patching your services and developing exploits usually. So, then organizers connects participants of competition and the wargame starts! You should protect own services for defence points and hack opponents for attack points. Historically this is a first type of CTFs, everybody knows about DEF CON CTF - something like a World Cup of all other competitions. Mixed competitions may vary possible formats. It may be something like wargame with special time for task-based elements (e.g. UCSB iCTF). CTF games often touch on many other aspects of information security: cryptography, stego, binary analysis, reverse engeneering, mobile security and others. Good teams generally have strong skills and experience in all these issues. -- from ctftime

also you learn insane amount of python magic, like before the most complex code in python i could probably wrtie is for i in range(10)

the only magic in coding is template magic. and FISR

I am new to C, and i was just wondering say can i make a program that can take input without displaying it on the output?

you can't without rerendering the entire screen or using ncurses

Thanks a lot

In windowd you can do it

Windows

Actually, it is possible to disable input echoing with ANSI escape sequences on linux

Oh thanks!

And you can even make it output some other chars (usually *'s in password prompts)

wow!

But im not sure if that was a feature in conio.h (Wind0ze only)

Read a book about C++ instead of C

lol you don't even know what he would like to do

maybe he wants to contribute to Linux, who knows

lol you don't even know what he would like to do

I don't need to

maybe he wants to contribute to Linux, who knows

in that case, clinl

But im not sure if that was a feature in conio.h (Wind0ze only)

conio <-> iomanip

But im not sure if that was a feature in conio.h (Wind0ze only)

conio is non-portable and deprecated

conio is non-portable and deprecated

Yes

Thats why I warned about it

sry I am not reading everything 😆

there is still people who use it, so worth saying

mmm

This is some old C++ program for suppressing the text output

https://hastebin.com/gekacawiho.cpp

for windows

anyway for new entries, keep in mind that trying to learn the entire language (both features and standard library) (we're talking about C++) is a waste of time, I mean it is worth to have a somehow deep knownledge of C++ but without some theory on various fields of CS, you can't do almost nothing

I just saw that some people are trying to approach the language

I would say that learning the object orientedness in C++ is way more rewarding than memorizing the STL itself

Why memorizing the entire STL anyway... documentation exists and it is widely exhaustive

yep

and being familiar with documentation and semantics gets you far

in c++

that's why I prefer C, I like to be able to know that the way I'm doing something is the best possible one

that's why I prefer C, I like to be able to know that the way I'm doing something is the best possible one

thats the wrong approach to a good mindset

I like both languages

the standard library is always the most optimal

you yourself will often screw up trying to do taht

sometimes is needed to implement things by hand

sometimes is needed to implement things by hand

yes

but when you can, relying on a stl is very nice

Sure, but when there are million ways to do some string manipulation in C++, for example, I'm always left thinking "was that the best possible way to achieve it"?

still better than doing everythign by yourself

Ofc I try to use stl, but sometimes the bloated stl just confuses

I mean yeah the STL is actually great, functions are assumed to work very well and also well tested etc etc... and will fit in most applications

And then, there is BOOST LIBRARY on top of stl

but when it comes in build it yourself, I prefer C because it only brings you the tool to do that, not anything else

even if I am missing some C++ features

I liked the orthodox c++

Ok?

why is python associated with a chip

:DD

What is this graphic? Sorry I'm noob :s

it is way more to a higher layer than C

What is this graphic? Sorry I'm noob :s

Some false shit

Some false shit

😂😂🌚🌚❤️❤️

why is python associated with a chip

Maybe for arduino or something similar?

Can you code python for arduino?

Usually SoCs are C/some stripped c++

yes, I think some framework exists

Some false shit

C is great for what it wants to be That's the reason C is still widely used in embedded systems

Do u read yearly stats from Embedded space? C++ is taking percentages from C every year. Good thing many ever considered modern C++. Compilers are so good nowadays such that some Embedded devs can't give constexpr a pass.

Yes C++ does. However I do not consider C obsolete. It is easy to write a C compiler for any architecture and depending on your target architecture and your requirements c++ may not be a possible choice. As mentioned above there not a lot ASIL rated C++ compilers. And if you need to verify your code it is easier to do this in C than C++.

Yes C++ offers many language feature that make it easier to write safe code.

printf is dangerous

We have fmtlib a formatting lib to be standardized soon. No more stupid worries. Well I use C++ mostly anyway

again a language isn't defined by the compilers

I think he is just saying that implementing a C compiler is easier

not that C > C++

I think he is just saying that implementing a C compiler is easier

(which in fact is true due to the lack of features as opposed to C++)

and I am not saying that having features is a bad thing
