Hey @Downgoat I found something for you

@DestructibleWatermelon I think you accidentally rotated your chessboard; the corner colors are wrong.

why does it matter?

just rotate it in the fen or whatever

or reflect it

Q: How do I debug an emoticon-based URL?

You can't do that in FEN

I would, but then the pawn movement would be messed up

And black/white squares actually matter for this, soo...

Also lol:

I came across this URL and need to convert this to puny code. As an experiment, I'll paste this URL here, but not sure if this will save. http://🐒🍵🍱🍋🎩🍣🍕🍊.🍕💩.ws/ How can I convert this URL to a standard DNS name so I can whois the IP space?

So stack-based languages are too mainstream, I'm making a queue-based language

Ethics Dilemma:
I've got some useful code that implements web-scrapping techniques on a music downloading website. I'd like to put my project on github so I can talk to someone about it. I understand that web-scrapping is somewhat illegal however. It is safe for me to put that code on github or can I get in trouble?

Maltysen

@AshwinGupta you prolly won't get in actual trouble

Ashwin Gupta

@Maltysen Well, I doubt anyone will see it. Just wondering if I COULD get in trouble in the highly unliekly scenario someone did.

I mean, obviously if someone asked, I'd take it down. But could I still get in legal trouble if I took it down immediately on request?

I just don't want to do something stupid =/ if it can be avoided. But, using github is convient becuz syntax highlighting and all.

If you just want to talk to someone (or few people) about it, you could serve up your own repository instead of hosting it externally. Assuming you trust this person enough to give some basic info like IP address and such.

@StevenH. You use R twice though

R is a no-op since the result is stored in the register that R reads from, so it really shouldn't matter. I'll make that clear, though.

@ΛεγίωνΜάμμαλϠΟΗʹ Should it still be interactive in terms of input?

Should be optional IMO

@ASCII-only Also, leave a space. This is the right format:

Thing | Other Thing
----- | -----------
foo   | bar

That way it's really easy to put on TIO if you want

@mınxomaτ Recommended? Yes. Right? Yeah, but there are other ways to do it

@DJMcMayhem Use Vivaldi

I'll work on making it optional later, but did a quick and dirty command line file-read that should work.

@Mego Does using a grammar for the Seriously, GolfScript, CJam or Pyth challenge count for the bounty, or is it too close to writing an interpreter?

11:22 AM

What challenge?

@StevenH. this, look for "Mego"

@Mego would a neural net suffice?

11:47 AM

Anyone good at regex golfing online?

12:08 PM

You have to pay GitHub for the git LFS module to track files larger than 100MB (and pay for their bandwidth), but you can host huge files on the release tab for free. That makes no sense.

Lol

@Mego Or else would I be allowed to create something like a more powerful version of Retina?

@TimmyD Is there a way I can fake the user-agent to reflect a browser to download a file in PowerShell? Preferably in a single command.

@mınxomaτ Yeah. It's the -UserAgent flag on Invoke-WebRequest

Something like the following

Invoke-WebRequest -Uri website.com -UserAgent ([Microsoft.PowerShell.Commands.PSUserAgent]::InternetExplorer) | Out-File C:\temp\foo.blah

msdn.microsoft.com/en-us/library/…

Regarding the "ancientness" of the 90's: many of the languages created before 2000 (and some of the languages after) could be considered ancient. This could be especially true here, seeing as we seem to create a new language every few weeks.

) throws this error: Unable to find type [Microsoft.PowerShell.Commands.PSUserAgent]

@Mego I might. I tried M and ♂ while testing Actually from the command line and IDLE and I got a stalled interpreter.

Clearly it's your Python install's fault :P

Apparently IDLE is reacts badly with Unicode

But it's starting to baffle me how Dennis actually got Actually to run on TIO. I mean, seriously :P

12:46 PM

You can't mess up Windows 10. The reset feature is really mature in this version.

@mınxomaτ Which command not display anything? The powershell -command one?

@TimmyD Yes. I need to run that from a batchfile to download a thing (since GitHub now blocks BITS).

But the powershell progress thing takes over the console in a weird way.

@mınxomaτ Ah. You could try -Noninteractive

@TimmyD Still shows the thing.

I wouldn't even care if it was a sensible byte count, but no, PS draws over the top portion of the console window and misplaces the cursor.

OK, then you need two "commands" in your -command field. Separated by semicolon.

The first is $progressPreference=SilentlyContinue technet.microsoft.com/en-us/library/hh847796.aspx

It may need to be in single-quotes.

@TimmyD Yay. It works.

Woo!

And it doesn't have the weird priority issues that BITS has.
