Q: Do people in non-English-speaking countries code in English?

I've heard it said (by coworkers) that everyone "codes in English" regardless of where they're from. I find that difficult to believe, however I wouldn't be surprised if, for most programming languages, the supported character set is relatively narrow. Have you ever worked in a country where Eng...

Non-English-based programming languages

Non-English-based programming languages are computer programming languages that, unlike better-known programming languages, do not use keywords taken from, or inspired by, the English vocabulary. == Prevalence of English-based programming languages == There has been an overwhelming trend in programming languages to use the English language to inspire the choice of keywords and code libraries. According to the HOPL online database of languages, out of the 8,500+ programming languages recorded, roughly 2,400 of them were developed in the United States, 600 in the United Kingdom, 160 in Canada, and...

@Qwerp-Derp Your example using the recurring digits isn't clear (probably would read clearly with merely a reorganization; or something suggesting that this is a recurring decimal digit rather than a recurring fraction or something)

@ConorO'Brien No... bootstrapping is the name for writing libraries in a language using your own language, based on the idiom "pulling yourself up by your own bootstraps"; it's not the same as booting

Destructible Watermelon

booting does originate from the term bootstrapping though...

Booting computers nowadays is often done using bootstrapping. You have small, hardware-specific code (the BIOS) that runs slightly more general code (the bootstrapper) that loads the OS and runs it

Destructible Watermelon

The main difference is that UEFI takes the place of both the BIOS and the bootloader (which I accidentally called the bootstrapper)

The preprocessor is very very dumb. It can't do anything except for find-and-replace

I find non-SCU to be pretty relaxed for C/++. No more fixed order for function declarations. You also don't have to worry about include ordering at all.

H Walters

Well, it can do pattern matching and math

Anonymous

@HWalters It doesn't do pattern matching. It can only do "take this symbol and replace it with this symbol". And it also doesn't do math - that's the compiler.

Actually, no, it can do both

That's what chaos and order are for, they bring static computations and templating to the PP: chaos-pp.cvs.sourceforge.net/viewvc/chaos-pp/order-pp/example/…

Non constant math is still beyond the preprocessor though.

Math is done using #if (expression)

Not #define

Ok yeah you can do very simple arithmetic in the context of a preprocessor #if

Both chaos/order and P99 do some pretty ordinary integer math just with the PP. There's nothing really hard about it.

It doesn't look like a "call" to add(10,15) expanding to 25 for sure

Ok so I exaggerated a bit when insulting the C preprocessor. It's still not nearly as intelligent as a compiler.

mınxomaτ

@HWalters Well yes, if you would actually look at the example, you can build complex operations with basic choas atoms: chaos-pp.cvs.sourceforge.net/viewvc/chaos-pp/order-pp/example/…

H Walters

@mınxomaτ Exactly... but it's fun to hack these up from scratch (chaos-pp isn't doing anything magical)

Downgoat

also another question: I know I can add a folder to lookup in things like: #include "foo.h" with -I. But is there a way to add a folder to lookup for things such as #include <foo.h>?

H Walters

Meh... a bit lazy... here is a cpp bottles of beer program that does math

Anonymous

@Downgoat Uhh you're a bit confused. #include "foo.h" looks in the current directory first before going to system directories. #include <foo.h> only looks in system directories. You can specify additional locations included in the "system directories" with -I.

Not sure. How do you do that on a local machine?

H Walters

You can use g++ with g++ -E -P; or you can use cpp (preferably with -P)... and the output is just what you want

On TIO it actually goes past this if I try a C++ program and inject -E -P flags (-P is just to make it pretty)

Dennis

Compiler flags are planned but not yet implemented. In the meantime, you can always compile things from tio.run/nexus/bash.

my server is waiting for a specific domain, so simply hitting it through the IP won't work

@Dennis you are using Let's Encrypt, right?

mınxomaτ

5:52 AM

@Dennis Actually they don't. DNS changes are almost instantaneous today. The only issue that remains are misconfigured DNS caches usually run by ISPs. A good network with a good nameserver (like CloudFlare) will see no delay with any DNS change.

One can usually clear the ISP's cache by re-authing the router (turn off/on again) if you have a dynamic IP from your ISP.

Nathan Merrill

I'm using internetbs with digitalocean's nameserver

Dennis

That makes sense. When I set up a new sub-domain, it works immediately. But if I change it...

@NathanMerrill Yes, I do.

@NathanMerrill DO runs name servers? Are you sure you are not using IBS's NS?

Nathan Merrill

ns1.digitalocean.com

does it support all of the different methods?

like, I use the "enter this time-limited 6 digit code"

mınxomaτ

Yes.

It's standard compliant, you don't have to use the Google thing.

Nathan Merrill

what's included in the standards?

mınxomaτ

The server prints a QR code to scan into the console. (For setup, after that it asks for the OTP code on SSH login).

@NathanMerrill I mean that all RFC 2FA compliant apps can use this SSH extension.

There are companies like CloudFlare that require you to store the secret random seeds on a third party service (Authy). That violates the standard and locks you in one app.

@ErikGolferエリックゴルファー As zyabin spammed on The Remaining Bytes, he 'retired' of this site because of the suspension

Eᴀsᴛᴇʀʟʏ Iʀᴋ

which was for being overly dramatic and irritating in chat, but that's all in the past

no hard feelings

Sherlock9

@Mego Yeah, how can I rewrite the specification for clarity?

@TuxCopter Oh right. Although I dunno what "The Remaining Bytes" are?

Sherlock9

Also, what do you think of the title?

TuxCopter

@ErikGolferエリックゴルファー A Google space

ErikGolferエリックゴルファー

Weird. You mean Google Drive or something?

Oh, it's like chat-rooms. Now I've got to study (B I O L O G Y D A R N) so I'll be out. Then I also have Basket Ball practicing for 1h 15m (at 12:30 UTC).

Titles are literally the least important thing to me regarding challenges. As long as a challenge has a title and it is somewhat relevant to the challenge, I'm happy.

I would say swap instead of reverse

Kritixi Lithos

I've been having nightmares about accidentally entering rm -rf / --norecursive, so I just did alias rm="echo" in my .bashrc

Eᴀsᴛᴇʀʟʏ Iʀᴋ

why

that sounds like an awful idea

why would you even write rm -rf / --norecursive

Kritixi Lithos

Better safe than sorry

reverse makes it sound like you're reversing each of the pieces (so (0).(14)(15) would become (0).(41)(51)) - that would make an interesting challenge, but it's not the right terminology imo

With that change, I think it will be ready for main

zyabin101

@TuxCopter Okay :D

Sherlock9

Just finished a big change. Fixed some typos, and put some examples nearer to the beginning

zyabin101

@TuxCopter I'll invite you in the room right away.

I don't see any problems with it now

@ErikGolferエリックゴルファー Excessive hate, that is.

Though I'm also tired so YMMV

Sherlock9

For the others in chat, what do you guys think of my Sandbox post? meta.codegolf.stackexchange.com/a/10842/47581

Last call for suggestions and corrections

@Mego Thanks for your help. Get some rest when you can :D

@Sherlock9 I'll try, but insomnia sucks. For now, it's games.

Sherlock9

Ooh. Which games are you going to play?

Anonymous

I dunno. Might do some Factorio

Though replaying FEZ is tempting

Sherlock9

Alright the swap periodic/non-periodic challenge is going live

@Mego Ah I completely spoiled myself the first time with FEZ

Perhaps, I should replay it sans walkthrough, at some point

Kritixi Lithos

@Sherlock9 For the first example, shouldn't it be 142857/1000000 instead of 1/7 since it is not repeating?

Sherlock9

Yep

Anonymous

@Sherlock9 I did any% without spoilers, but I had to get spoilers for the last few anticubes for 100%

Sherlock9

This is why I ask for proofreading help :D

And thanks for reminding that I should get both Antichamber and Factorio in the Winter Sale

I've been meaning to go through those properly

Antichamber is sooooo good

Kritixi Lithos

I also don't understand why you converted the 1736842105263157895/1000000000000000000 to 347368421052631579/200000000000000000

I might do a few runs in that

Anonymous

If I feel especially fun, I might even stream it

Anonymous

But I probably won't because you shouldn't be spoiled

Sherlock9

@KritixiLithos The numerator and denominator both divide by 5

Nah, I've played some of Antichamber

Kritixi Lithos

10:33 AM

That makes sense

Sherlock9

To be honest, I tried it on a cracked version, but I didn't finish it there, because the cracked version doesn't save your progress

Although that does mean I shouldn't be spoiled on everything after the second gun

Anonymous

Which is most of the game :P

zyabin101

Gotta play RRT now :3

Q: Swap out some periodic and non-periodic parts

In the decimal representation of every rational number p/q, you have a periodic tail, a non-periodic head, and a section before the decimal point in the following format: (before decimal point).(non-periodic)(periodic) Some examples include: 1/70 = 0.0142857... = (0).(0)(142857) 10/7 = 1.428...
