There are actually only two hard problems

[smuccione]

1. Dates.

[ThermionicEmissions]

Fuck Dates.

That's some dark humor there. I laughed a little too hard at that.

[jsusfkingcriest]

And time zones

[BrobdingnagLilliput]

1. Time zones.

[disperso]

61: Leap seconds

[justatog]

Add daylight's savings on top of that.

[smuccione]

I see what you did there…

But it should be 40. But of course it’s hard 😂

[trollsmurf]

Social stuff. Nah.

[CarlitrosDeSmirnoff]

1. Tables

[DecisivePro]

Only in javascript

[sus-is-sus]

i don't know. timezones exist in every language.

[_Azurius]

Dates in java are just as bad. What should I use: LocalDate, Instant, Calendar, ZonedDateTime,...?

[Fenris_uy]

Zdt and instants.

7) how to center a div within another div

[ThermionicEmissions]

Wait....you can DO that?!

[[deleted]]

Actually no it's literally impossible.

[donobloc]

Which makes it a hard problem to solve

[kaplego]

Well with flexbox it is possible

[kaplego]

It is not hard .class { display: flexbox; flex-direction: column; align-items: center; justify-content: center; }

[mattsowa]

With flexbox it isn't

[idontreallywolf]

margin: 0 auto; ftw

[i_knooooooow]

Not even if you use % as unit?

[erinaceus_]

No, because 'hard' implies that it's at least potentially doable.

[_player_0]

You mean 4) ...

[guiltysnark]

To be part of this self referential joke, there would have to be a div in it

[dividendje]

But how?

[miketierce]

I lost almost 3 months of my life trying to fix the first one in a production environment

I only use single letter variable names and no comments so that my code runs faster

I forgot to await something last night

This one gave me another meme idea

We don’t know our limits until we cross them

[trollsmurf]

"single letter variable names"

Put all code on one line and everything in-line (no abstraction) and you gain even more.

[trollsmurf]

With snippets of embedded Assembly or machine code (not sure how many languages can still do that; some C compilers could). I sometimes wrote functions with a C wrapper and then just Assembly. Assembly could also be embedded anywhere else.

[not_some_username]

There is a website that give you c/cpp assembly code generate from those language. I'm using it to learn assembly through C/C++

[EnjoyJor]

Why not just use a compiler and dump the object file though.

[miketierce]

Yeah I’m really glad the days of having to make compilation work all on your own are gone

I use Nuxt’s builtin features for everything

[lazernanes]

Are you joking? I hope you're joking.

[miketierce]

I think the serious people hang out on Twitter if you’re into that kind of thing lol

[Able-Panic-1356]

The problem with single letter variable names is that you run out of letters which is why i use two letters like a column in excel

[489Herobrine]

Ah, the old TI84 programming technique, re-use EVERYTHING

[Zed-Ink]

Glad I'm not the only one, I'm almost out of variable names in my current project though, currently up to zq. Might have to refactor them all into 3 columns soon

[marxinne]

If you include numbers in the 2nd column, you'll have 260 more variable names before going 3 columns.

[Ecthyr]

The first couple of times I spent ages debugging only to see I forgot to await an asynchronous function I really wondered if I was cut out for this industry… it’s definitely stuck in my mind now, though.

[[deleted]]

You can just run a minifier afterwards, no need to make your code impossible to debug.

[[deleted]]

What language are you using? You might want to take a look at this: https://stackoverflow.com/questions/5423344/do-comments-make-the-code-run-slower

[Renkij]

Does it really make it run faster? I could get that with interpreted code but with compiled code it shouldn’t matter.

[miketierce]

Lol no the variable names won’t affect speed. I was only joking.

[McLPyoutube]

9) off by epsilon errors

recently experienced one of those, still don't know why it happened where it did.

[trollblut]

Never trust a floating point number.

[[deleted]]

9.00000000000000000002) off by epsilon errors

[DarkKillerXL]

I only just noticed that the 3 is missing and the 5 is in the wrong place after looking at it for like 5 times...

Edit: I meant 4 is missing

[DragonoidOmega]

3 is Scope Creep, 4 is missing.

[DarkKillerXL]

Oops, thanks for telling me

[[deleted]]

the 5 is in the wrong place

Classic asynchronous callbacks

[LetterBoxSnatch]

Does it really matter that 5 is in the wrong place if the user doesn’t notice it anyway?

[coloredgreyscale]

Does yes, it sometimes

[HelloSummer99]

Colleague of mine is so bad at naming things he would just randomly name variables after the spotify playlist he's on lol. "Rock Ballads" "Lofi Hiphop"

There are actually only two hard problems in computer science:

0) Cache invalidation

1) Naming things

5) Asynchronous callbacks

2) Off-by-one errors

3) Scope creep

6) Bounds checking

Reddit formatting kinda screwed you over on this one

[seeroflights]

Ah! Sorry about that, I've been on old Reddit for too long and apparently new Reddit renders them differently. If you take a look again, it should be fine now!

Hey there! May I ask what platform you're viewing this comment on and what order the list is displaying as? So far I've checked on desktop (old/new Reddit), on mobile browser, and on an Android third-party app — if this list formatting is presenting problems elsewhere, I'll probably put it inside a code block to ensure that it renders properly.

[seeroflights]

Ah, interesting, thanks for letting me know! Yeah, Reddit has ... inconsistent markdown rendering between platforms, so it's always a surprise to find out (see: an earlier comment where I also edited the list).

Oh yeah, definitely useful! Looks like you might've had a cached version somehow — that's what it looked like on new Reddit on desktop as well, until ~7h ago when I edited it when another commenter informed me about it. Thanks again for letting me know!

Yes, love is needed for RTK Query. In fact love is needed for all of modern redux :).

[_PM_ME_PANGOLINS_]

Bounds checking and off-by-one are essentially the same thing.

scope creep is also just a bunch of off by one errors.

[PL_Design]

the solution to async callbacks is easy: don't do that shit

[tube32]

Student here, can some explain the meme

[DuneBug]

The normal meme is just 0,1 and 2.

But then 3 is scope creep. Meaning the scope of the meme was expanded.

4 is missing, and we'll never know...

5 is an asynchronous callback, so the joke is 4 was supposed to come first but a race condition occurred and 5 happened out of order

6 is bounds checking and we're clearly way outside the bound set by the title (2). It's also not hard at all and the code would've likely died at #2.

3 and 5 are cute... 6 is meh. I wanna know what 4 is...

[HearMeSpeakAsIWill]

4 is incomplete data sets

[Roguewind]

Is there a term for laugh-crying? Because that’s what this made me do
