@Dennis can you add Condit? theanythingbox.com/software/condit

Dennis

@Chance Geez, so many NSFW language names... I'll take a look. Which one was used in the polyglot?

@Pavel Sure, but not right now. Currently in the middle of some backend/arena modifications.

Pavel

Ooh, interesting. Here's to hoping nothing borks!

Dennis

It shouldn't. Nothing exciting. A bug fix and some minor tweaks so I can run automated test. Also a step towards test suites, polyglots, etc.

Pavel

@Dennis command mode isn't working for me, the gear activates for a split-second and stops.

Chrome, Windows 10.

Dennis

03:34

Only R or are the other shortcuts also affected?

Pavel

Just R

It activates, but nothing is executed.

Dennis

Alright, I'll take a look. It works if you click, yes?

Pavel

Yeah

I spamed Esc and R for a bit, and it ran eventually, have not been able to reproduce.

Dennis

Same here.

ATaco

Happening on Firefox, Windows 10 too.

API update bug?

Dennis

03:46

I don't think it's related to the API. I always use Ctrl-Enter to run code, so I'm not sure when it broke.

ATaco

I too use Ctrl-Enter...

Pavel

TIL Ctrl-Enter is a thing you can use.

ATaco

It's a POLA thing, most IDE's and such support Ctrl-Enter

Dennis

It's also in the mouse-over text.

Pavel

I might be alone on this, but I generally don't read the mouse-over text on a simple run button.

1 hour later…

@Dennis Can you please pull RProgN-2?

Dennis

@ATaco Done. The JAR file doesn't seem to have changed though.

ATaco

I forgot to rebuild! Let me do that real quick.

Done.

Dennis

There it is.

ATaco

592^^ should now print the rediculously large number: 413590306276513837435704346034981426782906055450439453125

Pavel

05:30

What notation is that?

ATaco

Reverse Polish B)

Pavel

No, what is ^^ doing?

ATaco

592 is being interpreted as 5 9 2, which is then 5 81 as 9 2 ^ = 91, then, that big ol' number is 5^81

Or, To the Power Of, I guess.

Pavel

Oh, so 2^9^5 in infix.

What if a want to use the number 592 literally?

ATaco

5^9^2 in infix, actually.

And so far, "592"n is your best bet.

Or use the flag -Z and don't use ZSS.

Pavel

05:40

I feel like there should be a better way.

ATaco

I've been thinking of making Something in the same vein as double qoutes, but I've not thought of what yet. Maybe $592$

Pavel

It's golfier if you leave off the last $ and just parse the number until the next non-digit.

If you need to push two numbers in a row, $123$7^ still works fine

You lose bytes if you need to push a long number followed by multiple short ones, but that's not very common.

And pushing multiple long numbers is considerably shorter.

ATaco

Regardless, golfiness isn't a high concern for me right now.

@Pavel there is a mouse-over text?

7 hours later…

Chance

14:52

@Dennis It was the top one. Alphuck I believe.

@Dennis hi, SQLite is quite different and not that powerful; I know almost nothing about selinux, but there should be ways to sandbox postgres; if it helps, you can disable sockets and use only pipes

as I said, you can ask for help on freenode, and I heard they're quite responsive in the mailing lists too

4 hours later…

19:14

@Dennis Can you please pull V?

Dennis

@aditsu Pipes would be an improvement, but the user-provided snippets should not be able to interfere with each other or change the system in any meaningful way. Each one would have to run with a separate database which is destroyed on exit.

@KritixiLithos Done.

Kritixi Lithos

Thanks :)

aditsu

19:42

@Dennis I think you can create a new database and a new role (user) with only minimal permissions for each run

or you could have a reusable pool

Dennis

When we both have a moment, could you talk me through this? I've never used SQL.

aditsu

never? :o

I can't talk a lot right now, but I could answer some simple questions if you'd like

Dennis

Apart from a Hello World script in SQLite, never.

I'm also kinda busy right now, and it's actually a bit too early for me to ask questions. Whenever you have time, give me a ping. :)

aditsu

sure, hope I remember :)

1 hour later…

Pavel

20:50

@Dennis can you redirect some short names of languages to their proper address? Like, redirect tio.run/nexus/java to tio.run/nexus/java-openjdk, tio.run/nexus/prolog to tio.run/nexus/prolog-swi, etc?

I frequently access a language directly by url and it just doesn't work sometimes >_>

Dennis

Doesn't autocomplete already take care of this?

Pavel

Sometimes, but not always.

Which leads me to visiting tio.run/nexus/j a whole lot.

Dennis

Anyway, if you want a quick way to access a language by URL, java-openjdk.tryitonline.net will autocomplete a lot faster.

Pavel

Right.

@aditsu SQLite is adequate in most scenarios where you are not planning to have a lot of parallel writes (more than one thread writing to the db at the same time). You can have simultaneous parallel writes occasionally and still be fine though. That's the biggest limitation of SQLite in terms of "power".

SQLite is vert lightweight, it ususally much less hassle than postgre. But yes, if you need advanced processing or write concurrency it does not work so well

@Dennis sqlfiddle does something similar. Without selinux of course ;) sqlfiddle.com

It looks like the idea that you create an empty database for each run and tear it down when finished

But user, of course has to provide the actual schema they need
