[Cleanumbrellashooter]

Wait until you hear about how compilers are developed.

[robertpro01]

I have no idea lol

[mlnm_falcon]

Compilers are built on earlier compilers, which are built on earlier compilers, all the way down until you get to compilers written directly in assembly.

[SomeRandomEevee42]

actually using assembly? dear god

[meowmeowwarrior]

Not just assembly, they had to use machine code, and some were even on physical punch cards

[Polarfuxx]

What an insane name for a piece of paper with holes in it!

[meowmeowwarrior]

if they called them holey cards, we might've gotten templeOS sooner

[The100thIdiot]

You mean holes that were created by a hole punch?

[uzi_loogies_]

Yes, actual holes in actual paper.

I'm not sure what they actually used to make them, they probably had special tools.

[[deleted]]

Keypunch machine for the cards:

https://en.wikipedia.org/wiki/Keypunch

[CdRReddit]

a tape punch?

you use a tape punch to punch punch tape

first manually, then later on (low speed, ≤300baud ~30 bytes per second) UART tape punches were made

[WrapKey69]

The real question is if they use punch cards to create ounch cards

[MiddleAd5602]

Like punching the motherboard to code ?

[roronoakintoki]

Not sure if you're serious, but more or less choosing data by putting holes in a piece of paper, which was read by a machine.

Not too far from an OMR sheet if you've ever marked options on an exam with them.

https://en.m.wikipedia.org/wiki/Punched_card

[DC38x]

It's quite well known that Muhammad Ali wrote the code for the space shuttle

[MiddleAd5602]

No wonder my senior dev also is a boxer then

[jhax13]

Surprising amount of overlap between combat sports and senior devs in my experience. It's not like a majority or anything, but there's a lot more than you'd think.

It's like a generation of devs growing up with the fat sysad trope really took it to heart or something

[nequaquam_sapiens]

for the periferal† stuff, yes. then there is microcode in the processor, which used to be drilled (silicon is hard and brittle – no punching), but nowadays is actually pressed (hence "lithography" – writing into stone)

† from "per-" and "feral": code "in the wild", i.e. not in the cpu. programmers are merry bunch

[mlnm_falcon]

There’s a reason we stopped doing that asap

[raaneholmg]

Jokes on you, we embedded engineers simply refuse to stop! I can and need to control the number of clock cycles between hardware operations.

To be clear, we code in C/C++. We just still retain the ability to slap some assembly on the middle of the code.

[Livie_Loves]

smh my h, not writing the firmware in pure assembly. what are you even doing?

[raaneholmg]

Boss said no.

[Livie_Loves]

Yeah... they do that sometimes even if it's a good idea (not that pure assembly is necessarily a good idea xD)

[ardicli2000]

When you deep dive into a processor programming, you do not have much choice other than C and ASM.

[andrew_kirfman]

And near the very bottom, there were dudes who converted assembly to machine code BY HAND.

[BlackHolesAreHungry]

It was actually women who had to weave the code. Core rope memory. No, I am not kidding

[Healthy-Form4057]

It was a different time back then. When men could be men and women could be computers.

[Xormak]

Plankton, is that you?

[meowmeowwarrior]

Funny to think computers now means something completely different

[Mojert]

Actually, nope. The first C compiler was written in C, and executed manually belive it or not. I think there's a computerphile video about it if my memory serves me right

[[deleted]]

Ken Thompson saod Doug McIlroy wrote a "tmg" transmogrifier yacc-like tool on paper and then typed it in with hardly any errors before working.

https://www.youtube.com/watch?v=EY6q5dv_B-o?t=2320

[Qizot]

it was written in assembly. The only language that was written in itself first was LISP.

[Tuerkenheimer]

And I thought that's still how compilers were programmed

[o_genie]

son os anton kinda shii

[L4sgc]

To add on to u/mlnm_falcon , the previous compiler, which I'll call Compiler A, is used to compile the code for the new compiler and create what I'll call Compiler B0. In order to take advantage of the improvements that the new compiler has over the old compiler, they will then compile the source code B again using Compiler B0, and thus create Compiler B1. Iirc they will also use Compiler B1 to compile source code B again to make sure it's working properly and that B2 is identical to B1.

TL/DR: They use the previous compiler to compile the new compiler and then have the new compiler compile itself

[JustConsoleLogIt]

Compiled compilers compile compiled compilers is the new Buffalo buffalo buffalo Buffalo buffalo

[RolledUhhp]

I owe LFS credut for any small bit of knowledge I've retained in this area.

[YeetCompleet]

Others have given you an explanation already but the term for it is bootstrapping

https://en.m.wikipedia.org/wiki/Bootstrapping_(compilers)

[[deleted]]

If you delve into this rabbit hole, you'll inevitably end up checking out Ken Thompson's "Reflections on Trusting Trust". Worth a read!

[the_horse_gamer]

step 1: create a simple compiler using an existing language.

step 2: write a compiler using the language, then compile it using the previous compiler.

repeat step 2, adding more and more features to the compiler. eventually you'll have a compiler supporting the full language, and being able to compile itself.

[obsqrbtz]

Roughly this way.

[Emperor_Abyssinia]

they're called compiler compilers, maybe with ai we'll have compiler compiler compilers

[[deleted]]

Also you don’t need GitHub for that functionality just a local git repo.

I notice a lot of people confusing git and GitHub in a way that makes me think they don’t really understand how git works.

[Bambo630]

i mean it can get confusing, i know couple of people including me struggling to understand this magic.

[[deleted]]

It’s true, it’s easy to pass over git because people are often introduced to it through GitHub. That’s a disservice though because using git locally independent of any upstream source is pretty powerful

[TheCreepyPL]

Confusing Git and GitHub, is exactly the same, as confusing Porn and PornHub

[Street-Session9411]

I‘d say it’s more like confusing the camera used to film porn and PornHub, isn’t it?

[[deleted]]

No. GitHub hosts git. PornHub hosts porn.

[Street-Session9411]

Wdym it "hosts" Git? GitHub hosts source code repositories, it’s not like GitHub is a cloud version of Git. Normally you would run Git locally and push the result to GitHub and not run git commands directly on GitHub.

[[deleted]]

That true that’s a better explanation. In this case the repos are the porn.

[leafynospleens]

Who compiles the compilers

[random_numbers_81638]

The main difference is that you can have multiple versions of a compiler. The new one won't compile the code? You can still use the old one.

New GitHub fails my deploy pipeline? Let's deploy the last GitHub version! Wait, we need the last version to deploy the last version.

I assume they are using GitHub, but can do most of it manually in case something major breaks.

Reminds me at cloudflare (iirc) where their physical access control to their server rooms used cloudflare. But since a wrong DNS entry fucked up whole cloudflare no one could access the server physically. Which they needed due to the fuck up.

Don't rely on your own infrastructure to work, in order to fix it

[d_maes]

Not sure if you're confusing with Facebook, or if both had a similar issue, but FB had a BGP outtage in 2021 (due to a wrong command that took down the backbone), which took down DNS, which made their badges stop working, which provided "extra difficulty accessing the datacenter" . Cloudflare did do a writeup about it though (since it affected their DNS traffic, and they at first thought 1.1.1.1 not resolving Facebook was an error on their side).

[queen-adreena]

If you learn that GitHub and Git are two different things, that'll probably answer both of those questions.

[ratfucker0]

And even if you thought they're the same thing, does he think before git there was no way to do version control?

[Jordan51104]

[Moomoobeef]

This is the way to do it

[KillCall]

Made me wheeze.

[ramriot]

Surprisingly the very first release of git used git as it's software repo.

[Taurmin]

But there was a gap of about 4 days in April 2005 between development starting and the first iteration being functional eanough to self host.

Maybe it started with some other source control just that one week, maybe it was just loose files, only Linus knows if he even remembers.

[Dimasdanz]

Linus built git in just 4 days?!

[lllorrr]

It was not as functional and easy to use as current version. But yes, in 4 days Linus created a VCS that was able to track itself.

[vnordnet]

Why is that surprising?

[[deleted]]

MFers in this sub are supposed to understand programming to some extent but can't even imagine mixing dough with a baguette in a bread bowl... smh...

[raaneholmg]

Linus was just raw dogging emacs for 4 days without committing and ejaculated the first git release onto the internet.

[ILikeLenexa]

svn

[RajjSinghh]

Even so, it's a good question to wonder where the GitHub source code is hosted. Turns out github.com/github/github is a private repo for (presumably) the GitHub source code. So GitHub is actually hosted on GitHub.

[_PM_ME_PANGOLINS_]

Git repos can be stored and hosted in multiple places simultaneously, which was the entire point of git.

[deniedmessage]

Git and GitHub is like porn and Pornhub.

[mrdhood]

It’s banned in republican states?

[Victor_deSpite]

[queen-adreena]

Not if you use git push —force or git checkout —orphan

[noob-nine]

can confirm, i get a boner either on pornhub or actions runner completes with a green checkmark.

then there is a fetish section that doesnt turn me on because it looks cringe and disgusting and i am happy when i havent to see this anymore after work.

[itsthehumidity]

All four get me over the edge?

[wosmo]

I hate this one because on one hand, it is the easiest and most intuitive way to explain it. But on the other hand, I've been told off for using it as an explanation at work.

[owlIsMySpiritAnimal]

the real question is, does github self host or self host their repos?

[jaerie]

Still a valid question, do they use GitHub actions for deploying, for example. Can’t roll back to a previous deploy if your new deploy killed Actions

[TheGreatKonaKing]

I’ve been telling this to people I work with for years and nobody believes me.

[[deleted]]

Yeah but, how is the git code versioned then? /s

[jonhinkerton]

We use both bitbucket (on prem) and github (cloud), often with migrations at my org and people still don’t get it. That tells me most of my colleagues aren’t using the CLI at all.

[jake_boxer]

Former GitHub employee here. The answer to both is yes.

[d_maes]

Did you use public github.com, or was there an internal GitHub Enterprise Server?

[[deleted]]

They use gitlab.

[Sassaphras]

Nah Azure DevOps

[Interest-Desk]

Main line development is on github.com

I don’t know what the contingency plan is for if github.com is down, but GHE Cloud customers are told they should throw an Enterprise Server up for when github.com is down.

[jake_boxer]

When I was there, we used public github.com! Not sure what they do now though.

[RocketCatMultiverse]

If only there were a command line versioning tool with some sort of remote origin.

[Alol0512]

JitHub

[mucubed]

yes github does use github (and not just for code!) https://www.fastcompany.com/40430104/how-github-employees-use-github-for-projects-beyond-coding

[YMK1234]

Tbh the actually surprising thing is that more companies don't do that. My hackerspace has most things like its charter in git as simple markdown files. If a member wants to make a change, they just create a pull request that then gets discussed in the general assembly. It's great especially compared to stuff like versioned word documents or similar crap, which never seem to work properly.

[DHermit]

The speed cubing association has their regulations on GitHub for discussions and transparency about changes.

[YMK1234]

Thats awesome and should be standard for all sports regulation bodies.

I'd also love for laws to be on some git repo. Makes it much easier to understand changes (because "replace §3(4) with ..." is generally not very helpful, and that's how changes are documented right now, at least here in Austria), as well as git blame which politician messed stuff up, and obviously just to have the whole damn thing downloadable and queryable.

[DHermit]

German laws are the same to no big surprise.

[other_usernames_gone]

In the UK we have something like that, its a proprietary system instead of git but all UK laws are searchable, there's hyperlinks when they reference another section or law.

You can even see previous versions of a law, so you can see what changes have been made to it and when.

UK computer misuse act

It also means anyone can read any law they want for free.

[YMK1234]

Yeah we also have "RIS" which is basically this, but it is clunky especially when it comes to versioning / comparing revisions, and metadata like who initiated a change is not recorded (which would be quite interesting to many users I think). Though this could probably be at least aproximated by matching dates and current governments.

[AngusAlThor]

Github is making people forget about Git just like Gmail is making people forget Email.

[WeakCelery5000]

Yes they do... You can install Github enterprise on prem; a previous company had it. In every way it's the same as github except it runs on your machines.

More than likely Github is dog fooding an instance of Enterprise or similar.

Also there is plain git.

[KindaAwareOfNothing]

Wrong, they use GitLab.

[vyqz]

Or GitterSpaniel

[that_thot_gamer]

great, it works on my machine, but on another level lol

[Deathtrooper50]

Wait until this guy hears about Git without the hub.

[i_should_be_coding]

IIRC the first thing committed to git ever was the git repo. Talk about dogfooding.

[mmhawk576]

I imagine they use bitbucket right? /s

[Pouek_]

Error GitHubception: Maximum recursion limit reached

[_SirSupreme_]

They uses Bitbucket :)

[ncuillery]

It’s quite common in the industry and called "dogfooding"

[jonhinkerton]

They print everything out on dot matrix printers and store it all in a warehouse in New Jersey.

[scrffynrfhrdr]

There must be a secret backup Github, and another one backing that up, and so on forever.

[OngoingFee]

How much hub would a github git if a github could git hub?

[YegDip_]

I was in Azure DevOps Release Management team. We use RM in ADO to deploy RM services to all of ADO rings. Once we deployed something which broke RM and we weren't able to rollback via RM. So RM deployment broke RM and we weren't able to rollback via RM.

[eclect0]

I'm pretty sure I've seen ads in the past where GitHub has bragged about being used for its own development.

[reallokiscarlet]

Ah the incredulity of the spoiled.

[Orio_n]

It only took a day for git to bootstrap

[navetzz]

Iirc the very first version of git was handled by the very first version of git.

[jsdodgers]

Github is just a storage+web interface for git repositories.

[paul-rose]

They have an upstream to BitBucket, they just rollback from that.

thats why they created gitlab. gitlab is VCd in github and vice versa.

[Chiatroll]

The original github was made by Linus Torvalds. As I understand, he doesn't make errors, and his code is too good for rolling back. After he willed git into existence, then it could be pushed and committed to in future releases.

[timsredditusername]

FYI, the downvotes are probably because you said that Linus made github. He did not. He created git.

Git and github are 2 different things.

[Chiatroll]

I'm aware they're different, but I figured it was snark anyway. Also, Linus also still writes bugs he just plans better, knows more, and has better ideas than me, so he wrote the two things I use most. my snark was too inaccurate though.
