@Adám Does Dyalog have it's own HTML templating system?

stuck at 88% validation accuracy

it's time to go deeper

orrrrr I could get some data that doesn't suck

hmmmmmm

ASCII-only

@ConorO'Brien ok how to pass argv to atstate

Zacharý

@ASCII-only What is this for?

ASCII-only

@Zacharý attache

Zacharý

@ASCII-only Ah.

@quartata how bad is overfitting for you?

quartata

02:13

I didn't get any overfitting after applying L2 regularization

@quartata on embeddings?

quartata

the weights of the fully connected layers

@ASCII-only like you would a normal program?

C:\Users\conorob\Programming\attache (master -> origin)
λ cat test.@
Print[Arg[0], ":o"]

C:\Users\conorob\Programming\attache (master -> origin)
λ attache test.@ hello
hello :o

@ConorO'Brien :O

crap

i already did a PR, you might want to change it to normal

Conor O'Brien

did you see the changes I requested on your other pr

@Pavel I'm sorry, I don't know what HTML templating is. Can you elaborate?

Pavel

@Adám Most web frameworks have their own "language" which is basically an HTML template with content that can be filled in by the framework

Adám

@Pavel Ah. Well, Dyalog APL doesn't have any HTML capabilities out of the box (other than ability to parse XHTML). MiServer has its own "language" (i.e. an extension of APL) that lets you construct HTML with no HTML/JS knowledge, using only APL syntax. Here is an example.

Pavel

That's pretty cool

Adám

06:07

@Pavel Yeah. One of the things I like the most is how it makes HTML array-oriented. You can make an entire HTML <table> (i.e. with <thead> and <tbody>, each with <tr>s that have <td>s/<th>s) with just New _.Table myMatrix''1.

ASCII-only

06:59

@ConorO'Brien why n+1 though

Conor O'Brien

@ASCII-only argv[0] is the filename I believe. That or the script name

keep in mind optparse is at work, and so a command line argument will always be present, thus the +1.

ASCII-only

@ConorO'Brien will always be present?

@ConorO'Brien but apparently optparse removes all of that?

idk. pretty sure it happened when i was testing

Conor O'Brien

Optparse removes all flags and flag arguments, but stray arguments are left untouched.

can you repro my example earlier locally?

ASCII-only

07:22

@ConorO'Brien example?

Conor O'Brien

@ASCII-only yeah the one I used to showcase ‘Arg`

ASCII-only

ah, i see

@ConorO'Brien wait. there is something to prevent do, ] right

Conor O'Brien

prefer { and } to do and end

ASCII-only

@ConorO'Brien i mean in attache you check that people don't do do <body> ] right

Conor O'Brien

07:37

@ASCII-only you mean, detecting matching braces?

ASCII-only

yeah

Conor O'Brien

Should be in place. You could check it on tio

ASCII-only

07:53

oh. yeah >_>

Add annotations to your #python functions to give hints about how the function is supposed to be used. (They are not type checks and they don't alter python behavior!) def myfun(a:int, b:int) -> int: return a + b

how do we deal with a challenge that needs to go back to the sandbox? vtc it, then reopen the original sandbox post?

dzaima

@ngn AFAIK there isn't a standard (maybe there actually is, though I haven't seen any in action, but if not, someone should meta it)

Pavel

@BetaDecay I annotate literally every named object in my Python code

@Pavel I had no idea it was possible

Honestly, I can't believe this hasn't already been asked, but here it is Background Given a simple undirected planar (the graph can be drawn in the plane without intersections) graph, it is a proven theorem that the graph is 4-colorable, a term we will explore in a bit. However, it's far easier...

AdmBorkBork

Happens all the time in PowerShell.

Pavel

20:20

That's cause in Powershell stuff is named Get-Content instead of cat

Zacharý

unless you use the aliases, if I remember correctly, there are alot of aliases.

Pavel

cat is an alias for Get-Content, yes

As is type

But if you're writing a script, the VSCode extension and other linters will complain at you for using them

Adám

Wait, cat is the program you use to temporarily disable your keyboard so the cat can't destroy stuff by stepping on keys, right?

Pavel

@Adám Not in PowerShell

Zacharý

⊢ on the contents of a file, if you are legit asking.

@Pavel I'll keep my cat and ls, thank you very much.

Pavel

20:29

Yep, same

Adám

@Zacharý That'd be , no?

Pavel

I use coreutils with powershell instead of cmdlets

On an unrelated note: I have some Py2 code that looks like this: item_list = [[x['key'], x['key2']] for x in my_dict.itervalues()] . The dictionary is really big, thousands of items. How can I make this as fast as possible? I've tried builtin map and it was significantly slower.

Zacharý

>_<

Pavel

item_list does need to be list, other kinds of collections don't work.

quartata

20:46

@Pavel It'll probably be faster with plain .values

Pavel

@quartata What do you mean?

quartata

Does the inner part have to be a list or can it be tuples

Pavel

Has to be a list, unfortunatly

Hold on, it's faster with a for loop and list.append

Like, a lot faster

That's pretty weird

Loop time: 86.7649998665

Q: Divide the work

There is a job which can be decomposed into x equally-sized smaller tasks. You have a team of size y <= x, where every member works equally fast on any task. The goal for this challenge is to divide the work as evenly as possible such that every member of your team has at least 1 task to perform....

CMC: Show an underscored t.

Erik the Outgolfer

@Adám t̲? not sure what you're asking

Adám

@EriktheOutgolfer Yeah, hm, I'm trying to find a way to avoid loopholes like that.

H.PWiz

That is rendering as t_ for me

Erik the Outgolfer

combined char issue?

Adám

21:09

The idea here is a minimal challenge that forces you to actually format some text.

H.PWiz

No, If I go to "history" it looks right

Adám

bolded and italic letters exist in Unicode.

And colours can easily be done in terminals.

Erik the Outgolfer

@H.PWiz is it an issue only with t̲ or with both t̲ and t̲?

H.PWiz

Only the last looks fine
