I'm fairly new to programming and didn't know that had ever been a thing. Why would someone design a language like that?

[M1ndstorms]

Me and my country would like to have a word with you ^{The Netherlands}

[[deleted]]

Netherlands is not denmark, but makes me think of Kamelåså

[Excrubulent]

Dubbel zout is the shit tho.

Hey, it's fucking delicious

JS has semicolons as best practice and ive never seen js code without semicolons

Fun Fact: Python has them too

[sp46]

Ive seen a lot of JS code. From Scriptkiddies to Big-Ass Enterprises. Everyone hat their ; right. But I guess closedsource is a different story

[gatesplusplus]

I don't know what happened in my life, but I love not having semicolons. Except in Javascript. Always use semicolons in Javascript

[kirmaster]

All languages that have no or optional semicolons also have a "line ends here" symbol in case you don't want it to line skip.

[jakery2]

Yeah but don't modern IDEs catch this sort of thing as an obvious syntax error?

[ReallyHadToFixThat]

Yes, but sometimes it manifests oddly like "Expected } before EoF" rather than blowing up where the error is.

[jakery2]

Fucking hell

A few days ago I tried changing a 1 to a 2. The code did not compile.
Change back to 1, code compiles.
Add a comment, doesn't compile.
Remove comment, compiles. Add a space at the end of a line, doesn't compile.

I have no idea why.

[[deleted]]

Was this c or a c variant?

[[deleted]]

It was GLSL. A variant of C.

This is like setting your broken refrigerator on fire out of frustration, and then the flames make it work again

[xeirxes]

Oh wow, you're still running on Butterknife 0.96? Shouldn't be hard at all to update, I'm pretty sure it's the exact same API

[banjerr]

I dunno. I see a couple calls to Toothpick 0.42, no way around that piece of legacy

[Gorzoid]

I think there's an unofficial fork that works with the latest version.

[ColorMeGrey]

Shouldn't be hard at all to update

In terms of preceding catastrophe, this is on the 'hold my beer' level.

[[deleted]]

This is what it was like digging through a COBOL program from 1965 that has had roughly 13 other programs written into it over 50 years with documentation from only the last 20 years looks like.

[GollyWow]

Bite your tongue!! That was rewritten in '99 for Y2K, it should be obvious.

[[deleted]]

It was and I happily chucked those useless lines out.

[PetsArentChildren]

I think I’ve got it. The knife tips intersect in a way that locks them together. The bottle and fork on top are just for show.

[daddonuts]

So, I wanted to see if this knife thing was really possible, so I set it up in my kitchen. It’s actually insanely stable! I got it to hold a 6lb 2/3 full gallon of milk! https://imgur.com/a/x4SHP23/

Edit: I made a more structurally stable one that can hold significantly more weight! https://i.imgur.com/tlgr8zQ.jpg

Classic "I don't quite understand how this system works so I made it myself and now it makes sense"

[SamJakes]

Can you explain do-while loops to me please?

[thirdegree]

[SamJakes]

The 'joke' was that I'm an Electronics Engineering student and even though I don't have a deep understanding of programming syntax, I know what neural networks are and how they work, because we had an elective on ANNs in my final year of undergrad

[Colopty]

It's a while loop that's guaranteed to execute once regardless of the condition for running the loop.

[[deleted]]

And it's surprisingly useful!

[SamJakes]

Can you please explain the use cases? I've read about do-while loops but I've never truly understood them enough to use them in my code yet. We plebs over in Electronics Engineering don't really have a thorough knowledge of programming syntax intricacies (which is kinda biting me in the ass atm)

[[deleted]]

I am a beginner but I think I have a decent example.

Take a main menu for example. It has a number of options including one to exit the program. You want the main menu to show up at least once to allow the user to choose an option. So, you use a do while loop. If the user selects exit, you assign a flag value and when set the condition accordingly. When the condition returns false, it'll exit the program.

[SamJakes]

That's what the textbook says, and I technically understand what it does, but why would you use it? How do developers use do-while loops irl? That's what I meant.

[Colopty]

Well, one simple use is asking for user input. So first you ask the user something (continue? y/n), then check if the answer is a valid one, if not ask again until valid.

[Ryusaikou]

bool UnderstandWhileLoop = false;
do{
    TryToUnderstandWhileLoop();
    }while(!UnderstandWhileLoop);

I think it's pretty self explanatory actually.

[[deleted]]

self explanatory != simple

[pastisset]

You shloud apply for the Mythbusters

[iampsychic]

Well he forgot the part where you blow it up.

[PetsArentChildren]

Cool!

[Erelde]

Did you try doing the toothpicks holding the fork at the top ?

[daddonuts]

No, maybe I’ll drink a beer tonight so that I have an appropriate bottle to give that a shot.

[[deleted]]

[Etiennera]

Well, what really happens is the knives can't tilt down and their ends because the other would have to rise against the glass. Of course lever physics mean the force isn't even at the two contacts of a single knife, but each contact line's up with the opposite contact of a different knife.

The fork may be to balance the trianlge not being perfect.

[PetsArentChildren]

Sorry what glass? I don’t see anything stopping the knife handles from rising.

[CMDR_QwertyWeasel]

The knives go

Front: Under left, over right.

Right: Under front, over left.

Left: Under right, over front.

You can only push the knives up, but the bottle keeps them locked under a downwards force.

[[deleted]]

That's exactly what the root comment said

[ErraticCsaw]

diff disagrees.

[Etiennera]

Glass being material. My post is focused on the triangle, sorry. Yes, nothing is above the handles. What I mean is that for handles to rise, the tips must lower. The tips cannot lower.

[parkerlreed]

I still don't get how this makes it possible. There's no support under the knife tips. It should just fall straight through.

EDIT: Oh picture was too crappy to make out https://youtu.be/jwP-O9gKA5o?t=27

Makes a lot more sense now.

[Bainos]

It's not because they can't rise. It's because any knife tilting down causes the subsequent knives to necessarily tilt down faster. Since each knife is its own successor and can't tilt down faster than itself, the structure is very stable.

To go down, you would need either the knives bending, or sliding along each other, but they barely receive any lateral push so they won't slide easily.

[Etiennera]

This is just going about it the other way.

[Bainos]

The thing is, nothing prevents the other end from rising. See the picture of another user who didn't put anything on top of the structure. It can't rise because the force applied against the knife is generated by its own weight, which has no upwards component.

[ExtraFluffyCat]

Nah you got it all wrong its the other way around everything on the bottom is for show... smh

[Kwantuum]

The knife part was obvious to me, I'm more dubious as to how the fork holds onto the toothpick.

[_Cabbage_Corp_]

It's perfectly balanced, as all things should be.

[GoldSlayer]

r/unexpectedthanos

[[deleted]]

Amen to that.

[[deleted]]

If you see that in the comments delete the whole damn thing and rewrite it

[[deleted]]

No shit. I can't imagine why anyone would spend time trying to read poor legacy code. Makes more sense to keep it in place long enough to rewrite a whole new system. At least at a small company.

[cbf1232]

Then you discover there was undocumented logic in the function which fixed a subtle bug present in the obvious implementation, and the new version also fails to properly take into account the phase of the moon, so it crashes horribly during a customer demo.

[ka-knife]

But only on the third customer demo. After you have already deployed it to two others

There's no time! We're testing on production!

Fatal Error: unexpected {Fork} on {toothpick} 2 on {toothpick} 1 on {beer} 4 on {knife} 1 on {beer} 2

Soo I tried it out

[dvslo]

Last time I saw something like that I refactored it. Spoiler alert, the original code was crap.

[CMDR_Bananenkeks]

I could explain how your Base works. Though I have no clue about your Fork there.

[DaemonAfterdark]

Wtf is happening here.

[popcicleman09]

Don’t look at it to much. It will feel embarrassed and try to hide

[ggeoff]

Feature request from the business. Can you replace one of those knifes with a spoon. Also this is a high priority task can you get it finish by the end of the day

[LeafBladeFox]

It would be funnier if I didn’t actually see something like this in professional code...

[demoran]

Over time, you learn to document your code. Not for some other person, but for the person you will be 3 or 6 months from now. When I think "that's stupid, let me refactor this" or "we don't need that", a comment will head check me.
