Are you serios? there are a lot of courses on Udemy to do that.

>blockchain

not impressive

>OS

impressive

>cryptocurrency exchange

impressive but probably a scam

>language

not impressive

>>964282 (OP)

That depends whether or not you are a deranged schizocow with a one-tracked mind.

a blockchain is literally just a linked list

1. OS

2. Language (if language is good)

there is actually big gap here, but you didn't give more options

3. Cryptocurrency exchange

4. Blockchain

>>964296

For the gap:

>graphics editor

>office suite

>web browser

>>964282 (OP)

>OS

>language(assuming it comes with a bootstrapped compiler)

>crypto exchage (imagine a thousand different things between language and this, the challenge with a crypto exchange isn't coding, it's not jewing the people using it)

>blockchain

>>964296

Hmm, I somehow didn't realize when I wrote this post fuck did I sound like a pajeet.

>>964339

The challenge with a crypto exchange isn't jewing the people using it, it's not getting jewed by the SEC and IRS.

>cryptocurrency exchange

Has be solidly build. Fuckups could be a disastor.

>OS

This mostly just deals with reading a lot of documentation.

>blockchain

Just a datastructure

>language

No coding required.

>OS

<by a lot, not even close!

Requires top to bottom knowledge of the architecture, ties it all together, provides I/O, and a context for other programs to run. Even a shitty O/S has to be pretty extensive, and a decent will have threading which is another beast. Has the most moving and varied parts of the other options; extremely impressive if implemented correctly and even moreso if useful for real-world application.

>cryptocurrency exchange

This is just application programming; it's not difficult conceptually, but it's a lot of work and polish to do it right.

>language

Ranges from easy (domain-specific languages) to hard (modern programming language). Writing a compiler is actually fucking simple if you're using the right tools. Doing it from scratch would be a nightmare; we stand on the shoulders of giants.

>blockchain

Dead-simple to implement, because again, you're standing on the shoulders of giants and reusing all of the cryptographic mathematics. The various blockchains available tend to add novel features on top of this; they don't reinvent the fundamentals.

>a blockchain is literally just a linked list

I came here to post this, good to see someone else gets it.

>>964315

>OS

>web browser

Come on. Like there is a difference.

>>964411

Riddle me this. If compilers are simple to make, why do they take two hours to compile?

If compilers are simple to make, why is getting a cross compiler build such a fucking shitshow.

I'd say something like TinyCC is impressive considering it seems to be a reasonable c-compiler in roughtly 1% of the loc of gcc.

>>964467

8/10 made me chuckle

>>964293

OS takes literally the same amount of knowledge as language (whether natural or programming)

>>964282 (OP)

blockchain was just one trick to make work

>cryptocurrency exchange

gay web forum tier shit

>>964468

optimizing compilers are harder to make, but less desireable anyway

>>964315

>office suite

>web browser

lol no

>OS

Wrote a basic kernel (if you can even call it that) once which runs a basic shell (help, echo, rainbowtext on VGA console, basic math) and reads keyboard input which took weeks, most of which was bootstrapping the build system, trying to wrap my head around a memory manager and reading. It's definitely tedious, but once you finish up the internal kernel parts enough to write a userspace around, it will start to get super fun.

>language

It's really simple to tie up an LLVM ExecutionEngine to a front-end that generates something LLVM can understand. You can have the frontend in any language, have it generate JSON for the LLVM IR, convert the JSON to actual IR instances in C++ and pass it to the EE (also in C++). It even runs as a JIT compiler so you can have a managed language.

What's the hardest thing to do programming wise?

>>964518

True AI

>>964507

How is a modern game engine below language? People design and implement languages on their own all the time, there are only a handful of actually usable game engines though.

>relaxed stability FCS for military use

>Heart-Lung machine controller

>Turbojet FADEC

>automated coolant circuit in a PWR

Which of these would be the most difficult/impressive to accomplish, /tech/?

>>964282 (OP)

OS ~ Language >>>>>> Cryptocurrency exchange >>>>>>>>> Blockchain.

OS and Language are kind of tied together, if you remember how C and Eunuchs were tandem.

Cryptocurrency is webdev. It's just putting together blocks, and the big work is in the logistics (like legal).

A blockchain takes a few lines of Ethereum contract code, which you can copy and paste.

If blockchain was so easy everyone would do it and do exit scams up the ass

>>964591

Only works if you have solid enough marketing to make an exit scam feasible. Getting an adoption base is much harder than making a blockchain.

>if ice cream has no bones, then how many pancakes does it take to cover a doghouse?

Basically you.

>>964490

No one has ever managed to create a good web browser though.

>>964641

chrome is fine you dumb faggot

>>964641

This is because the web itself is terrible. Saying there is no good web browser is like saying there are no fun toilet cleaning products.

It's hack on top of hack on top of hack.

TL;DR: You can't polish a turd.

>>964282 (OP)

OS

>>964651

its not the web it's designer that don't know how to make a website

>>964654

If you won't admit that the underlying structure of the web is broken then you can't really have looked closely at it.

html is kind of ok, in itself.

javascript is a clusterfuck.

css is one of humanity's most evil creations.

There are tools to make it better like less/sass, typescript, frontend frameworks, but these are just automated turd polishers.

>>964664

I agree. PNG is an stupid format, we have better compression algorithms than deflate. SVG is the worst format (not even a format, just xml) ever created to store vectorial art.

>>964674

And then you have the fucking web fonts. Multiple format grouped together to add portability, it's insane.

>>964591

all you do is fork bitcoin. there's even programs to do this for you. there are millions of shit altcoins for this very reason

>>964819

Well if you are allowed to fork projects all of these are trivial.

>>964675

To make sure your font is displayed in every browser, you need to make sure you have:

.EOT (Embedded OpenType, IE8)

.WOFF (new browsers)

.WOFF2 (latest browsers)

.SVG for good measure

It's a fucking mess.

>>964638

wtf ice cream has bones???

>>964893

Some do. Most ice cream is deboned at the factory these days.

>>964897

Is this true?
