Q: Evaluate a string as a verb in J

TL;DR Given a string containing a (valid) verb, how do I obtain that verb without committing it to any variables? For example, say eval is that function; it should work like this: eval '+ @ >: @ %' +@>:@% eval '+' + I only need it to be able to execute verbs and return them, but it woul...

I like to answer SO questions when I have time to kill (like Public transport)

Hey @Downgoat, does istanbul give you accurate code coverage results?

I have successful tests running that should cover most branches, yet my tokenizer is completely red on istanbul

Downgoat

@Quill take a look at the data. It should tell you what lines of code are covered and all

Quill

only the export default class instance gets hit

Downgoat

Can I see your coverage reports?

@QPaysTaxes why does this have 3 stars?

I'm literally crying on the inside right now (not becauseof the lenny). I can't possibly fathom why or even how someone would use a JS build tool with Java or PHP

Quill

Finally watched 2001: A Space Odyssey, and wow, is that movie boring. At least by modern standards, anyway. You could easily shorten it from 2.5 hours to 1 hour. And the ending was quite confusing; I feel like I need to read the book to really get what was going on.

Alex A.

My girlfriend is a film buff and loves 2001. I didn't find it that interesting, honestly.

I'm glad I've seen it though because I'm able to spot references to it in other media.

El'endia Starman

Yeah, it was definitely interesting seeing the multiple ways that it inspired Star Wars.

Quill

@quartata They're both "not" javascript and they use Gulp

Dr Green Eggs and Ham DJ

I haven't watched that movie, but I've seen clips of the "daisy" song.

Does that count?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

bai

quartata

03:47

Uhh... but they are JavaScript with wafer thin abstraction layers. I don't see how that justifies using a JS build tool for something not remotely connected to JS or potentially not even related to web development

Helka Homba

@El'endiaStarman Lots of iconic movies (and books) have illogical scenes. It's what non-programmers call "art".

Quill

@quartata there's probably a few hardcore gulp fetishists out there that use it for non-JS reasons and then Gulp just bullshits the numbers

Alex A.

What happens if req_buf_size overflows?

(Also note that int is 32-bit by default on Windows and 64-bit everywhere else)

Q: Can I use jQuery or JS to rotate a canvas image around its center?

Simple question, I'm drawing an image on the canvas using ctx.drawImage(img, 500, 500); I want to rotate this image around its central axis an undetermined degrees measure (somewhere from 0-360). I know that there is a jQuery library called jQuery rotate. However, I looked at the API of this, and...

javascript jquery canvas rotation

well this is what happened:

Wow, canvas rotate() is definitely working here :D!! (HEAVY SARCASM)

@QPaysTaxes If you're talking in general, I don't know. If you're talking something that you coded yourself in JS where the slash does something else, then event.preventDefault().

@QPaysTaxes Oh yes, I know. I had that problem myself a couple months ago.

event.preventDefault(), like I said.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

within the called function

El'endia Starman

Wherever you do what you actually want to do when the slash key is hit.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

textbox.addEventListener("keypress", function(e){e.preventDefault();textbox.value += e.keyName}

Kind of primitive ^^^

El'endia Starman

There must be a setting somewhere that you can adjust to move the functionality to another key or to disable it altogether.

Q: Actually Integer Metagolf

Background Actually (the successor to Seriously) is a stack-based imperative golfing language I created in November of 2015. Like many other golfing languages, it has one-byte commands that perform different functions based on the contents of the stack. One of its specialties is mathematics - it...

math number optimization stack metagolf

Reference answer (maybe working, maybe not): lambda x: ":" + str(x)

Sp3000

@Mego "Based on my experience, I'd wager that any 32-bit signed integer can be represented using 6 bytes or less." Please do tell if you ever get 4374732215 in 6 or 7 bytes because I spent two days trying to golf that number down in CJam

Probably easier in Actually/Seriously, but still curious

AZG

08:58

Hi guy, I'm trying to write a program that can crack xor ciphers when key length is known
And I've run into a logic problem. Mind helping?

Sp3000

What's the problem?

AZG

Okay so let's say I know the key length is 10

So i split the cipher text into 10 streaams

so every letter in one stream is xor'd with the same character

right?

Sp3000

Yes...

AZG

So I have to try 256 keys on each stream

so how do I know if I found the correct key in a stream?

If the whole ciphertext was encrypted with a single character key, I can just print the text given by all 256 keys and see which makes sense

Sp3000

Do you know what the plaintext might be like? Is it just text?

AZG

09:02

Yeah, like a paragraph

of normal text

Sp3000

How long?

AZG

The ciphertext I'm using now is taken from the old PicoCTF 14, it's....long

Sp3000

Oh, that one

AZG

several paragraphs

Sp3000

Well, for one thing, not all keys give printable ASCII/newline for the whole stream

So that's a start

AZG

09:04

Yeah I'll elimiate keys that give non-prinatble charachters

but that should still leave a few possible keys for each stream

Sp3000

The second thing you can do is some frequency analysis

Chances are lowercase e is the most common for at least one of the streams

AZG

okay...

Sp3000

Basically, try assigning each stream the key that decodes the most common char to e, and see if the output is somewhat readable

AZG

okay. I'll try that. Thanks

Sp3000

Dunno if it'll help (it's been a while since I did that one), but hopefully? :P

Web devs who download things like jQuery, Bootstrap etc. really annoy me. It more than often breaks things when the actual library gets updates. Just use the CDN link. It's also easier on your user's cache. (And you get SRI).

@MarsUltor Because when you change the link from a local file to the CDN link, and some functionality depends on older versions of that library, the you have to fix those. These issues go unnoticed when you host your "own" snapshot of the lib.
