Culture War Roundup for the week of November 28, 2022

This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.

Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.

We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:

  • Shaming.

  • Attempting to 'build consensus' or enforce ideological conformity.

  • Making sweeping generalizations to vilify a group you dislike.

  • Recruiting for a cause.

  • Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.

In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:

  • Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.

  • Be as precise and charitable as you can. Don't paraphrase unflatteringly.

  • Don't imply that someone said something they did not say, even if you think it follows from what they said.

  • Write like everyone is reading and you want them to be included in the discussion.

On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

one requires coding, understanding the design of complex systems.

Yes, that's the millwright job (if you can't handle the math to reason about them you don't get the ticket to practice it). The style of programming "language" they tend to use is also one not many conventional developers even know exists.

By contrast, Devops is generally a simple position- generally alternating between "fix the hardware and the racks", complaining that the software running on said racks isn't their department, and claiming that they don't have time to grant access to the resources development needs to do its job any time this year because reasons. (Apologies to you if that's your trade; I'm sure you're one of the good ones.)

Most software engineering for that matter is also relatively simple labor- the thing that makes it engineering is that you have to do the design work too, and make sure every component interoperates (and is even fit for the task in the first place), and if it doesn't work (or stops working) they're ultimately in charge of modifying it so it does, and the list goes on. Sure, it can be a bit trickier because everything's virtual, but the upside is that all the error messages are generally in plain-ish English rather than "it makes a weird grinding sound but only below 2/3rds power".

It's depth that's not necessarily obvious unless you've actually seen it, but you do actually need a decent amount of brains and general systems knowledge to do either job well. It's like saying "yeah, anyone could do software development because 99% of it is just implementing CRUD over and over again"; it's technically true but an over-simplification.

I'll accept much of devops like that, but twitter really does have 100Ms of users, global scale, and a realtime timeline, search, ads, replies, etc system, that have to be understood, monitored, designed to operate fail in recoverable ways despite very complex interactions of all the systems even when being actively changed. Many of the SREs elon fired weren't just rack swappers, they were coders who designed systems to preemptively avoid complex failure cases. According to him, his job started as you say, but that changed -

When I joined the team the first project I had was to swap old machines that were being retired for new machines. There were no tools or automation to do this, I was given a spreadsheet with server names. I am happy to say operations on that team is not like that anymore!

And then

We had bugs where new cache servers wouldn’t be added back(race condition on start up) or sometimes it took up to 10 minutes to add a server back(O(n^n) logic). Since we weren’t bogged down by manual tasks thanks to all of this automation work we could develop a culture in the team where we could go and fix these while keeping projects on track.

Sure, it can be a bit trickier because everything's virtual, but the upside is that all the error messages are generally in plain-ish English rather than "it makes a weird grinding sound but only below 2/3rds power".

The actual error is sadly only rarely actually pointed out by the error message. Compiler errors are straightforward, runtime errors are not, and runtime errors in complex interconnected systems may as well be Kafka's Prozess.

And the largest category of errors doesn't even have messages.

Fully agreed on DevOps though.

True, that's why it's plainish English.

Hell, even the compiler errors aren't straightforward the less structured the language gets; it's even better when said compiler does shit like "you meant for that object to not have its keys named the same thing, right? I'll just do it automatically because... fuck you, I guess".

It's a mess I'm not convinced even AI tools will be able to solve, so maybe I should just be thankful for the job security.

In what language do compilers do that? The horror!
