I want to contribute to open source OS like ReactOS or HaikuOS

Then go ahead?

Learn how to build them from source first then see where that takes you

I've been coding in C and C++ for around 2 years till now...i've worked on small projects...but now I want to contribute to OS development...how should I proceed? Should I learn linux kernel development or driver development? How can I get into core OS development?

wiki.osdev.org

Anyone looked at the original release of C++ C source code ?

Thanx...this is what i was looking for

You can't. just discard the newline characters while ((c = getchar()) == '\n'); if (c != EOF) { ungetc(c, stdin); }

thanks a lot!

Thanx...this is what i was looking for

<3 it helped me bunch... There is also some resource on YouTube... But I dont have link rn and I'm in train

Does anyone know how to write c codes for uploading a file and image??

Computers generally count from 0 to some value. For example 0 to 31 for 32 bits, 0 to 63 for 64 bits, 0 to 7 for 8 bits and 0 to 15 for 16 bits.

This is just wrong.

This is just wrong.

So wrong

This is just wrong.

Ask the hardware people🙈

At 15:30:08 UTC on Sunday, 4 December 292277026596, 64-bit versions of the Unix time stamp cease to work, as it will overflow the largest value that can be held in a signed 64-bit number. This is nearly 22 times the estimated current age of the universe, which is 1.37×1010 years (13.7 billion).

If 64 bit counts till 64, then how is it possible?

Two trillion $2 trillion $2,000,000,000,000 1 billion seconds = 11500 days 1 trillion seconds = 31000 years In computers, the CPU (central processing unit) and other components such as RAM and the video card speed is measured in Hz or MHz (Megahertz) and now GHz (Gigahertz). One GHz equals 1,000,000,000 (one billion) Hz.

A 64-bit register can hold any of 264 (over 18 quintillion or 1.8×1019) different values. The range of integer values that can be stored in 64 bits depends on the integer representation used. With the two most common representations, the range is 0 through 18,446,744,073,709,551,615 (264 − 1) for representation as an (unsigned) binary number, and −9,223,372,036,854,775,808 (−263) through 9,223,372,036,854,775,807 (263 − 1) for representation as two's complement. Hence, a processor with 64-bit memory addresses can directly access 264 bytes (=16 exabytes) of byte-addressable memory.

You are contradicting yourself

lol

No that is what I said

0 to 63 for 64 bits

The format got corrupted https://en.m.wikipedia.org/wiki/64-bit_computing

0 to 63 for 64 bits

What is wrong with that....🤓

What is wrong with that....🤓

It's 0 – 2^64-1 unsigned.

What is wrong with that....🤓

The decimal number 63 fits into 6 bits

Hopefully this format helps With the two most common representations, the range is 0 through 18,446,744,073,709,551,615 (2^64 − 1) for representation as an (unsigned) binary number, and −9,223,372,036,854,775,808 (−2^63) through 9,223,372,036,854,775,807 (2^63 − 1) for representation as two's complement.

You were saying it's 0 – 63.

We are not talking decimal but binary bit representation 63 bits down to 0 is very common in Hardware Description Languages as they represent the actual registers on silicon.

Was there a misunderstanding?

Computers generally count from 0 to some value. In hardware For example 0 to 31 for 32 bits, 0 to 63 for 64 bits, 0 to 7 for 8 bits and 0 to 15 for 16 bits.

I did say bits not decimal

Computers generally count from 0 to some value. In hardware For example 0 to 31 for 32 bits, 0 to 63 for 64 bits, 0 to 7 for 8 bits and 0 to 15 for 16 bits.

NO.

Lol

With 32 bits, you have 4 bytes, so 0 – 2^32-1.

You see you even had to write 32-1🤓

😂

That's (2^32)-1, not 2^(32-1).

this is just retarded

not sure if troll or serious

You see computer need to have a concept of zero

That is why a loop which tests for zero is much faster

...

You see computer need to have a concept of zero

You are limited by not understanding the hardware

Thus you are limited.

Great🤓

Lost in translation🤓

You're either an idiot or a troll.

Thanks Rose

lol

An idiot troll? That's impossible.

Troll inherits Idiot tho

hehe

At least there is some action on this group🤓

You can't lose mathematics in translation.

but how to provide 4 characters without pressing the enter button?

U can use space

Anyone actually seen this before?

In a loop

Shut up, Engineer.

Anyone actually seen this before?

yes and I recommend you to watch it

I was there

didn’t absorb the knowledge though

Are you trolling me now?😳

Officially

Fantastic!

I have followers now

An amazing Sunday morning

You see, computers really don't give a shit, they just shuffle around bits

what about quantum computers

I asked him, if 64bits counts till 63, then how's this possible? I didn't asked anyone to teach me about Epooch

what about quantum computers

We won't really get there until reversible logic gates happen
