"Money is not the most important thing in your life, what's important is knowing how to parse JVM" -Tsoding

I like how he reflexively keeps typing semicolons at the end of lines and correcting it

I just wanted to say how much I enjoy watching your videos. It is the perfect balance between top quality educational content and really funny/entertaining jokes mixed in. You truly are a one of a kind engineer. Keep up the fantastic work and I hope things are not too bad for you in Russia. Tsoding rocks 👍

in python3 with f strings you can do foo = "a" print(f"{foo=}) which will print foo = "a" basically if you put an equal sign at the end of the block it will evaluate the expression and return its value and the expression itself as string great video as always bro

We had Jython in the past (java running python programs) now Pava (?) Python running Java. Letsgoo

He hadn't uploaded since the Russian mobilization started. I had started to worry for him. Glad to see he is alright.

Glad to see you back keep up the content, I love watching it in the background at work!

Glad to see you back. I hope you are safe from everything.

Some reasons why the binaries contain the class names: - debugging output, e.g. exception stacktraces - reflection - methods that print the class name, including default toString implementations and getClass().getName()

You are a wizard, love watching you work

Ooh man my favorite channel makes a video about my favorite language java best day ever

Being an old guy, I know why there are and ... It's from the teletype machine days. is a carriage return where the print head is physically returned to the start of the line. is a line feed where physically scrolled the paper up one line. No collusion involved. ;)

This was interesting to watch and I learned a lot. Thank you! :) You're clever and a quick thinker.

Really entertaining video, looking forward to the rest of this!

2:52 He checked the date to say what year it is

35:00 - Lol welcome to the spec. It literally says in that page they regret some of these decisions. But yeah, its not a horribly complicated spec, just got some quirks. 43:30 - Arrays of 'constants' of each type would actually be kinda cool.

im so happy i can listen to u again

ure the best programming related youtube content creator. keep up the good work

good to see you’re back🎉

dude, great to see you're safe! was worried when you went quiet after the draft was announced!

18:30 I think the "intention" of Windows (or DOS) having both line feed and carriage return together is a simpler printer driver, and laziness. Early matrix printers had different commands for line feed (moving the paper) and carriage return (returning the print head to the home position, this is where the name comes from). With having both commands directly in the text document, a printer driver can simply send the file byte by byte to the printer and it does the right thing. Unix and Mac preferred a single command inside text files, since in a text document there is not really a concept of carriage return or line feed, just new line. For parsing binary data from bytes, I recommend struct.unpack. It is a standard package, which allows for easier reading (and writing) of entire structures and can handle endianness as well.

I love that there is the development process captured in this! Building custom JVM is cool, but I like to see you adding new features and suddenly saying "this can go to a separate function". It is such a great learning material! I wish something like this was done 15 years ago when I started to code :)

Someone is overly funny and sarcastic than usual in this stream 🤣 Nice vid Tsoding. Learned lot.

We built a transpiler that can target multiple languages instead (we made backends for lua and php but built it to be extensible). The subset of the stdlib that we implemented is very small as it stands but also built to be extended using Java classes with native methods and annotations that provide the code for the different languages. The produced code also doesn't look great because it replicates the behavior instruction by instruction but it actually works quite good.

I was waiting for your video

My man, every time i watch your videos i feel stupid, but at the same time i always learn something new :) Let's hope all that shit ends soon, i wish us all peace.

Such a shame we had to give up Turing completenss to get Unicode in python 3... Btw, Java 18 or 19 finally got "script" files, where you can just start writing code without a public static void main and it just works™

By the way, try to disable "Turbo" (also called p-state). You can do that with `echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo`. This will disable your CPU from running on extra sShpPpiIieeed and will no longer give you a heatstroke while you using your computer.

Super cool, can't wait for more! Maybe an interpreter?

Just "reading" that title alone made me want to comment: You really are the Sado-Masochistic Dominatrix of Programming. G-sus Krajst: This is the epitome of perversion, lol - and i thought generating 6502-assembly from inside a BASIC V2 program and poking it live to replace the running kernel by triggering a soft-reset would be nasty - this is a whole nother level of dark-arts. Razpackt!

1:23:11 the best part of the entire live

Well this definitely got me down a deep rabbit hole

Hi (or privet, as a Russian I hear russian accent in your speech :D)! Thanks for the video :)

def pprint(obj): print(json.dumps(obj, indent=4, sort_keys=False))

You're a lunatic, man. Never change :)

Jython, perfect name dude ❤

Again GREAT VIDEO 👏👏👏👏

The real OOP were the friends we made along the way

I know it's too late to sugest a name, but if Jython is Python on JVM, JVM in Python needs to be Pava or PVM

There is a lot more incompatible change in Python 2 vs 3 but the print is the most noticable syntactically. The way strings work completely changed, splitting the str type of Python 2 that was basically just a list of bytes into 3 different type: str (unicode string), bytes (immutable list of bytes), bytearray (mutable list of bytes), breaking a lot of programms messing around with binary files. And a lot more stuffs even less noticeable than that.

That was fun to watch

I admittedly haven't watched through the whole video, but since you are using python 3 I recommend using format strings in prints, you can do a lot of the stuff you did effortlessly e.g. print(f"{foo = }") results in "foo = "

Knowledge of reflection and injection would be helpful for a project like this 😉

1:47:28 When you said "holy fucken shit"... I felt it in my bones.

I really like your spying videos

can you write assembly on an os level ? It's fun and easy if you stay 16bit because you still have the bios.

6:00 for the thing about open source as a means to exploit young enthusiastic programmers

2:08:58 could use the ,= operator (which is just weird tuple syntax)

I think this is the third time you've changed the thumbnail now 😂

19:35 Once a bunch of files i was reading in were getting cut of at random points, ends up the binary info contained EOF markers coincidentally, and reading it in non-binary mode would just make it quit reading the file when it ran into them.

imagine running this through jython

Hehe... Пива... Ehehehhehhehhh...

Since you did this, why not also write a program in Python that can decompile Java bytecode?

3:26 that is correct

Javas interpretation of UTF-8 is going to be a pain. Because if you start using emojis in the java strings there are going to be problems.

Tsoding adding all those parantheses might be his unconcious telling him to learn LISP

2:03:50 Yes! This is me programming in PHP 15 years ago. "Why does the function return allways null? Ah, because I haven't included `return result` at the end..."

1:38:10 Descriptor is the ()V (void) return signature with no args

what font are you using?

python struct module is also a good option

1:23:10 As a CS graduate, I confirm.

How on the Earth Java compiles simple write to stdout so long?

пива))

Make porth compile to jvm

гагага пива

Oh the inexplicably fantastic horror. I cannot look at it but i cannot look away from it

Hmm Feels like Porth all over again You say it’s just for hello world but I bet this will end up being a lot more 😂😂

oracle jdk😄

I guess tsoding was so afraid of enabling JVM developers that he decided to use python for this task.

print without () had security issues

So you were in Russia that time?😀

:D

My insides feel weird reading the title.

1:04:00 it's hard to convince my peers to do this versus blop chunks of code and debug little by little

i love the jokes here n there

"It's doable"

Next step, writing a Java library to parse CPython byte code.

Did you move apartment?

I liked the video but dislike the fact that you are not getting the money, if there is anything i can do let me know, i will be happy to support. I am from india and Russia is a good friend of India

I want to code something simple today he says 😂

Has nobody commented on "P0rn folder size at 14:45" - Too smol PepeHands :D

Mi vidas komentojn en la angla, mi vidas komentojn en la rusa, sed kie estas la komentoj en la plej bona lingvo? Ŝajnas ke mi mem devas zorgi pri tio! Ankaŭ, algoritma engaĝiĝo.

21:10 it's because return is a keyword and print is a function but was a keyword in py2

sorry, but how doesnt you back hurt when you stay sit for quite a time?

are we not going to talk about 2:52? Edit: Ok, I should've just kept watching...

23:45 I came, but only because I like pain or something

The most important thing we can do to combat AI code generator agents is write massive piles of the sh*ttiest code on the planet, like bash scripts that generate bash scripts

open source and hackathons are one and the same :D

Yeah, the whole point of Java is that you don't need to know how Java works internally.

Maybe yer laptop needs to be cleaned from dust ?

It would be rly cool if you could help free pascal with jvm backend

Java Bytecode in Python. Wow. How's the performance? 🤣

14:07 is really hot 🔥 😂😂😂!! in Russia 😂

1:41:00 incoming call

Un-staticize your interpreted language 😈

first!

может тебе создать русский канал? и заливать туда озвучки, на русском, или сюда добавить субтитры?

Whyyyyy? Just whyyy
