>>60952726
It's a pain in the ass, but I've been granted exclusive copyright to all my side projects at Google. There's the easy process, Google Open Source (in which Google owns the copyright), and the hard process, IARC (Invention Assignment and Review Committee), in which Google disclaims ownership of your idea.

In the IARC process, you send them a description of the idea, a lawyer reads it and checks if it counts as "competing with Google", and if not, they either ask you a few questions or just approve the project. It's really not that bad.

The thing that really sucks about working at big companies is how they drain your motivation to write code on your own time, at least for me.

Not all, but it's pretty restrictive... Most companies (like mine) have processes to register your project so it's separate.

Still though, NEEThood is a bit far lol, you can find plenty of places that don't have these kinds of intellectual property agreements.

>>60952764
Interns like me can't use IARC though, which sucks. I basically can't do anything the whole summer.

>>60952783
Yeah, but I also make >$200k / year in salary + stock + 401k match, and get to learn a lot about Google's internal architecture, and software development at scale. It sucks that copyright works the way it does, and the motivation drain really sucks, but if I didn't think it was worth it, I'd quit.

I'm also in the process of adjusting my sleep schedule so I wake up at ~4am, and can work on the business I'm starting with my best friend before heading to work. Hopefully that'll help solve my motivation / fatigue issues.

int main(void){
    char A1[] = ("color 0A");
    char A2[] = ("color 0B");
    char A3[] = ("color 0C");
    char A4[] = ("color 0D");
    char A5[] = ("color F0");
    char A6[] = ("color D0");
    for (;;){
        printf("PARTY HARD PARTY HARD PARTY HARD PARTY HARD PARTY HARD PARTY HARD\n");
        system(A1);
        system(A2);
        system(A3);

        system(A5);
        system(A6);
    }    
    getchar();
    return 0;
}

Hey, can I ask you an anonymous question about your project at Google? How often do your submits fail due to flaky tests, and how often is your project build broken? For me it's really hard to submit sometimes.

>>60952901
You kind of dodged the question there.

>>60952902
You're just mad you're not a Googler(tm). Have a look at this document to see the benefits of being a Googler(tm):

But you don't have the privilege (whoops, can't use that kind of language here!) to tell your friends (as if you actually have any) that you work at Google (tm)!

>>60952927
Our team has generally high quality tests. If the build is broken (or tests flaky), we discuss it at our dialing standup, and it is always fixed quickly. It's been broken twice in the 6 months since I joined the team, both by tests, once due to a dependency which didn't correctly invoke a presubmit, allowing it to silently break tests in our dependent code. The second time, it was due to a flaky integration test, in this case a simulated load test, which is obviously a more likely test to become flaky.

If you at all can, try to make a difference. Talk to your manager and see if you can dedicate yourself to improving project health for a quarter. When you're starting from so shitty, that kind of improvement can look really good on your promo packet. People recognize that it has a productivity-multiplying effect.

I don't know where most of your problems are, but Google has a lot of technologies for project health, so you should do some research. Ie, if you don't have hermetic integration tests, you probably should.

It'll also give you some diverse experience across the codebase, which puts you in a good position for coming up with new designs and leading major project efforts in the future.

The decision wasn't too difficult to make. Professors may be under a greater workload, but they also have a greater degree of freedom in what they choose to work on. Research doesn't have to be profitable to be publishable, so I can put my talents to something more fun than writing CRUD web applications all day in a language and framework that I'll probably hate.

I could try... but the problem is the failures don't really come from my area of the project. Maybe once I feel I'm comfortable on time for my OKRs I'll look into some of the failures and see if I can help. It feels a lot... bigger than me, though.

By the way, it's really awesome to see another Googler in this thread. Just wanted to let you know.

Yeah, exactly, that's why I've wondered if I'll do something past undergrad... I really can't decide, but the endless 9-5 sounds really draining to me.

>>60953342
Well pretty much all of these GitHub-type sites let anybody sign up and upload repos, since it's good for growth. Reviewing code is an expensive and time consuming process, so I wouldn't expect anyone to do that.

>>60953433
>I had to look up what the Mason-Dixon line was.
You're joking, surely?

>>60953339
>Maybe once I feel I'm comfortable on time for my OKRs
That never happens, in my experience. Or if it does, it's because you planned for too little, and need to take on extra work. If you don't make time for it, nothing under P2 will ever happen. And if you're not taking into account the time it takes to do good testing and monitoring when writing your OKRs, you're estimating them wrong.

>By the way, it's really awesome to see another Googler in this thread
Yeah, it's nice. There usually seems to be at least one or two Googlers in the thread.

I highly recommend keeping in mind how your team's project health impacts your productivity, satisfaction with your job, ability to tolerate dedicating so many hours of your life to Google, etc. It's pretty easy to transfer around inside Google. I was able to get a job in one of our smaller offices by schmoozing the right people (sent emails to all the TLs in the office, asking if they'd have any positions opening up soon. When they eventually posted the job listing on Grow, I was first on the list and got the job within a week).

Do what's best for your own career. If your team isn't addressing project health issues that are impacting your whole team's productivity, that's a really bad sign.

I'm not necessarily talking about gigantic first-tier enterprise stuff. Just useful stuff that isn't broken or never worked to begin with and consists of more than just "muh first binary tree". Now don't get me wrong I don't mean to denigrate new programmers as they have every right to publish their code, but I'm just looking for other public repositories with more interesting and thoughtful work.

The absolute most annoying thing is the incessant FORKING for no apparent reason. The pajeets especially are notorious for this and it fucks with my search results all the time. They have repos full of sometimes hundreds of forked projects completely unrelated to each other and in completely different programming languages and are never even updated after the initial fork. I don't know why the hell they're doing this because it's clear they're not contributing unless they actually need to compile all this software straight from source which I doubt they're doing either. Actually if there were a way to filter out all Indian repos it would make GitHub twice as good.

Sounds like youre desperately trying to cling to C when you know it should all be in C++ but your ego is clouding your judgement.

Also what are you doing that wouldn't be valid c++?

>>60953954
Is there a reason you wouldn't use object files? It just seems like making a library out of it is an annoying path to take, especially if you need to make revisions later.

>>60954033
He's not casting the return value of malloc

>>60954033
Last time I checked, C++ doesn't allow sparse selective assignment in initializer lists, anonymous structs and unions, implicit casting from void *, naming specific members to initialize in initializer lists, incomplete switch cases that abuse drop-through logic, etc.

>>60953954

>should I mix object files together, or should I compile the C stuff as a library and call it from C++?
Call C from C++, but not the other way around. Whether you want to compile to a library or just link in the .o files is your choice. Just use whatever requires less changes to your makefile.

>>60954033

Lots of valid C11 isn't valid C++. Mixing C with C++ is pretty simple as long as you're using extern "C".

What is an ``explicit recursions"?

>>60956516
I didn't disagree

>>60956523
If you want to do recursion you must explicit the recursion:
invalid

let fact n = if n = 0 then 1 else n * fact (n - 1)

valid:

let rec fact n = if n = 0 then 1 else n * fact (n - 1)

>>60956524
I didn't agree or disagree.

>>60956531
What are the benfits, you fucking moron.
I bet that's required because it'd be easier for the compiler to generate code.

My penis for a worshipper.

Okay, my assignment tells me to create a shortened constructor for greytones in a RGB coloring class.

What do they mean by that?
I did insert some conditions that should slowly ensure that all colors are equal for DAT GREY inside the constructor.
I have some unsure feelings that wasn't what was actually asked, right?

>>60956810

You're the guy from before right?
Grey colours have equal RGB values.
So in addition to your full constructor which takes RGB parameters, you should have a secondary constructor which takes a single parameter and sets this.red, this.green and this.blue to that value.
