The security of RSA basically relies on the fact that if a product of two primes is given, it takes too much of time to find the original two primes. Create an algorithm that, on being given a product of two prime numbers, will output its only two prime factors. Code golf challenge, so time wil...

Greetings, my friends

Mayhaps is anyone a user of the Windows operating system?

I require a John Favreau

github.com/ararslan/qqq-lang

Can someone build it on Windows and tell me if it works with the test files?

Calvin's Hobbies

I'm on windows but I dislike shouting birds

phase

ill do it bbycakes

Alex A.

@Calvin'sHobbies Fixed

phase

how do i build

Alex A.

6:12 AM

@phase THX BB

phase

i cloned it

now i confused

i see makefile

Alex A.

@phase Clone, cd to directory, make

I have no idea how to develop on Windows

So I don't know if makefiles do anything there

phase

@mınxomaτ hi

mınxomaτ

@phase ?

phase

I've got make installed

@mınxomaτ just thought I'd say hello

@AlexA. It's just kinda sitting there....

mınxomaτ

6:14 AM

I've been here for hours :)

Alex A.

@phase It isn't compiling?

phase

@AlexA. prntscr.com/91g8am

@mınxomaτ It showed your name just appear on the side

I don't really know what that means, but I assumed it means you just joined :P

Alex A.

@phase Hm. Well... Give it a sec? :/ I don't know. Do you have g++ for Windows if there is such a thing?

mınxomaτ

@phase Just type the GCC command. The makefile is not really necessary.

Alex A.

Or GNU Make for Windows?

@mınxomaτ I wanted it

phase

6:16 AM

if there is such a thing of course there's such a thing

Alex A.

I want to make sure the whole project works because I want to make a versioned release

mınxomaτ

@AlexA. For windows, I mean.

phase

oh wait this is C++, i no have dat installed

Alex A.

You don't?

:O

mınxomaτ

@AlexA. I'll try it. A sec...

Alex A.

6:16 AM

:D

Thx bb

phase

I've got gcc & clang but no g++

wait is g++ in gcc?

Alex A.

Uhhhhh I don't know

Clang might be able to do C++ but I'm not sure whether that's clang++ or some other kind of crazy thing

mınxomaτ

- C++ Compiler: C:\Program Files (x86)\Dev-Cpp\MinGW64\bin\g++.exe
- Command: g++.exe "C:\qqq-lang-master\src\qqq.cpp" -o "C:\qqq-lang-master\src\qqq.exe"

@phase Is the command for windows.

phase

(x86) is on 32 bit

mınxomaτ

So what?

It is still MinGW64, so 64bit.

Just replace the path with your MinGW installation.

phase

6:20 AM

well what if I installed it in a different place? how does one navigate through windows explorer!?!?!?

@AlexA. I've got g++ but the makefile is just stalling :\

mınxomaτ

@AlexA. pastebin.com/r5gZuXYe

Alex A.

@phase Is it in your path?

feersum

You can also get 32-bit compilers from mingw64 :P

phase

@AlexA. ofc i no how to add tings to ma path

Alex A.

set path=%path%;<whatever>

phase

6:22 AM

@AlexA. I don't have the dlls

Alex A.

@mınxomaτ OH SHIT IT WORKS! Thanks so much!

mınxomaτ

@phase Don't use the makefile. You don't have the make utility. Just use g++ -.-

phase

@mınxomaτ I did and I got the pic above

Alex A.

@phase personality_v0 it's saying you have no personality :(

I disagree <3

mınxomaτ

@phase You have a broken g++ install. Reinstall and stop trolling.

phase

6:23 AM

@AlexA. ----[---->+<]>---.---------

@mınxomaτ broken whaaaa

Alex A.

> stop trolling

lal

phase

no i just stoopid at cpp

mınxomaτ

@AlexA. Here's a binary if you want it: workupload.com/file/V9zQIrzn

Alex A.

@mınxomaτ I don't need the Windows binary for anything, I just wanted to make sure it works on Windows so I can do a GitHub release in good conscience. :P

Unless uploading a binary is part of that...

phase

@mınxomaτ hay you should check out my new webide localhost/link/code=11+o&input=

mınxomaτ

6:26 AM

@AlexA. You have a "bin" folder. That's usually where binaries go for users who don't want to recompile themselves.

So I assumed :)

Alex A.

Oh, I had that there because that's where the makefile writes the binaries

I actually had to add a .gitkeep in there otherwise Git wouldn't let me add the directory to version control

mınxomaτ

It's a single source file, so any directories or makefiles are a bit overkill imho.

Alex A.

Oh definitely.

But this is my first time with all this stuff so I want to learn. :)

Apparently I can add binaries to the release, so I'll add your Windows one there. Thanks so much for testing it for me!

And thanks @phase for trying to test it for me!

phase

@AlexA. yay, a medal for participation

Alex A.

Also lol @ 0.07 MB executable on Mac and 1.95 MB executable on Windows. :P

mınxomaτ

6:31 AM

I could golf that :D

Alex A.

Haha

Why the difference, do you know?

?

Overhead

^

Idk what that means

It's... over my head. B)

mınxomaτ

6:33 AM

Runtime checks, overflow checks, debugging symbols...

feersum

It statically links some libraries on Windows.

mınxomaτ

ld from gcc is also not optimizing.

For example, if you'd use crinkler as the linker, the executable would probably be around 1 to 1.5 kB.

Alex A.

uh ok

Thanks everyone!

Alex A.

What's the bug?

mınxomaτ

@AlexA. I don't get the quote thing. What would be the equivalent of [[][]]?

Alex A.

6:51 AM

" " ' " ' " ' " ", I believe

apostrophes toggle whether " corresponds to an open or close bracket

TanMath

hello!

Alex A.

Also @phase thx 4 folo me on gh bb <3 xoxo

@TanMath Hey, how are you doing?

phase

@AlexA. no prob bbycakes <456

mınxomaτ

@AlexA. That's weird. So it is a non-trivial replacement.

TanMath

@AlexA. good...i think I want to write a programming language...

Alex A.

6:58 AM

@mınxomaτ There are two major distinctions between how BF and ??? work: Traveling left of the starting cell in ??? is a no-op, and brackets use the same character but with a toggle character to switch between open and closed.

@TanMath It's fun. :)

mınxomaτ

> Traveling left of the starting cell in ??? is a no-op

Same for BF.

You should also mention that " is initially a loop-start.

Alex A.

Oh yeah, that'd probably be a good thing to mention...

Okay, done.

Thanks for the suggestion, @mınxomaτ.

undergroundmonorail

@mınxomaτ in my whole life i've used one bf interpreter that enforced that

it's probably worth mentioning that it's true about ???

TanMath

@AlexA. how do i start?

undergroundmonorail

first thing to do would be decide how you want it to work

Alex A.

7:06 AM

@TanMath Think about what you want to achieve. Will it be a golfing language? What will the syntax be like?

@undergroundmonorail Good idea.

TanMath

@AlexA. yes... i want each command to be one or two characters, and it will be like python...

undergroundmonorail

you might want to look at pyth as inspiration

although it's kind of taken its own path, it's not as much as python like it once was haha

phase

@undergroundmonorail O has a lot of inspiration from Pyth, including some of the same variables

Alex A.

Is O stack based?

mınxomaτ

@AlexA. I also see that ??? has no 8bit cells. That's worth mentioning. Also ! doesn't always output the character, but a hex number in some cases.

phase

7:11 AM

@AlexA. Yup. It's a lot like GolfScript/CJam

Alex A.

@mınxomaτ I don't know what you mean about the 8-bit cells. And yeah, I should mention the hex thing. I forgot why we did that. I think that was something I copied from a BF implementation I was working from.

mınxomaτ

@AlexA. Surely not, because a lot of brainfuck programs use the wrap-around at 255/0.

I.e. 8bit cells.

This program should keep outputting random bytes until forcefully closed. With ??? it outputs a bunch of hex numbers (some of them bigger than 255) and then stalls after a few bytes:

;;;.."-........"-"-..;,'";;'";;'".;;.'",",;;.---"-"--'"-.;";'";";;'"""-'";;",'"";'‌";",--'";'"-.-'"".--"-'";.-,'";;,"-!'",'";;"

Alex A.

The memory tape is a std::vector full of chars. I don't really know what I'm talking about, but I think that means that running past the whatever end std::vector allocated for it will just reallocate memory, so you can continue to move in that direction.

@mınxomaτ Try this in BrainSteel's interpreter: github.com/BrainSteel/BrainF-k

mınxomaτ

This is how the output should look like.

@AlexA. Easier, here's the 1:1 code from my example in C: pastebin.com/C2sxJkUp

Alex A.

./bf -L ??? -P smart ~/yourfile.qqq

@mınxomaτ Huh?

mınxomaτ

7:20 AM

That's the code.

Alex A.

For what? I'm confused.

mınxomaτ

How it should behave, implementation-independent.

Bad Cat Eye

@AlexA. When do you usually go to sleep?

mınxomaτ

@AlexA. You can convert BF to C. This is the 1:1 translation of the BF code I'm trying to run. That's how it should behave.

Alex A.

@BadCatEye Ideally? Like 10:30pm. Usually? More like 1:00am. :/

phase

7:21 AM

O got a new operator: N pushes a blank codeblock, saving you a byte insteaed of doing {}

Bad Cat Eye

@AlexA. Well there's your problem

Alex A.

What?

phase

u no slep

Bad Cat Eye

[tag:alex-is-...

With sleep, you could be right

Alex A.

My girlfriend is playing Fallout 4 since it just came out so I'm hanging out with her while she plays it. Special occasion.

Bad Cat Eye

7:23 AM

:D

mınxomaτ

@AlexA. Here's the brainfuck code. Because there are inconsistentcies about the functions of brainfuck, here is the C code that is generated by 1:1 search-replace of the brainfuck code.

Both should output and behave exactly the same way.

^

Monospaced font

A monospaced font, also called a fixed-pitch, fixed-width, or non-proportional font, is a font whose letters and characters each occupy the same amount of horizontal space. This contrasts with variable-width fonts, where the letters and spacings have different widths. For example, the two high-use letters "I" and "E" do not need the same footprint. Both letters differ in center-to-next-letter edge (and center-to-center) spacing distance needs (margins) in variable width fonts. The variable that changes is offset from what would otherwise be monospaced centering. In a modern proportional font, every...

@Calvin'sHobbies Perfect idea!

A: Why are there 2 ways to unstage a file in git?

git rm --cached doesn't unstage a file. It stages the removal of the file from the repo and leaves the file in your working tree, leaving you with an untracked file. git reset on the other hand, will unstage any staged changes for a given file. Edit: Thinking about it, though, if you used git rm...

That doesn't unstage

If I made a version control system, all of the commands would be from the Space Jam theme song.

Alex A.

@phase Can you do Run and Permalink on the same horizontal line?

phase

@AlexA. that's what I was aiming for, but I suck at all of the web stuff

I'm going to go google how to do that

Calvin's Hobbies

I'd also vote to put the byte count in line with the "Code" textbox header, or maybe under it like cjam does. Also the "O" in "O Online IDE" could be a link to the github and the "This is an IDE..." sentence could be moved to the bottom or removed altogether
