Blinkz0rz: May 27, 2001; MY CONTEMPT FOR MY OWN EMPLOYEES IS ONLY MATCHED BY MY LOVE FOR TOM BRADY'S SWEATY MAGA BALLS

kitten emergency: Jan 13, 2008; get meow this wack-ass crystal prison

ok so here's my terrible programming thing

we switched to slack at work and my bosses boss was like "hey I wish I could get notifications when I'm mentioned in jira comments sent to my slack account" so I think "well that's probably easy since slack has a jira integration"

turns out the slack jira integration only really does issue status changes. so I think that's weird, go digging into the atlassian rest API. turns out jira has no way to fire a webhook for 'person was mentioned'

so I google around, find someone else has had this problem, and wrote a golang app to fix it. so I turn that up, seems to work fine. boss says "that's neat but what'd really be handy is if when people mention this specific user it's go into a private group"

so turns out incoming webhooks to slack have no loving concept of private groups, only the slack api. so I rip out some stuff and do a quick and dirty wrapper around the slack web api which can message into private groups as well.

butttttt it turns out slack web api keys are scoped to the user that the key was issued for, which means I can't send messages into his special snowflake leads chat. but the bot api can send messages into groups if you invite the bot! so then I turn around, get a hubot going, integrate it

except node.js can't loving parse atlassians dumb poo poo atom tags so I can't just scrape the activity stream for comments in hubot directly. back to my golang app. rip some poo poo apart, throw a external call to a hubot listener, and finally I have what I was trying to do done.

unspoken in this is the amount of time it took to figure out how to pretty-print messages from the bot because the slack attachment format sender is completely undocumented unless you go looking for it in the source

FINAL TALLY
2 languages
2 dynos
1 redis cache

to send some loving messages to fancy irc

spent more time writing the app than i did waiting for licenses :toot:

CPColin: Sep 9, 2003; Big ol' smile.

On Friday, a coworker came over and asked for help brainstorming an interface or API or something that would reduce some duplicated code a bit. Fortunately, the code was only in two places, so I went, "Rule of Three!" and we both agreed that it wasn't worth it to abstract everything out yet.

Programming terribleness averted/reinforced!

rule of 3 is how you decide whether to factor out part of a function into a utility function or something.

tons and tons of good designs involve breaking your code down into functions where some critical functions are only ever called once by one other function but it's the most sensible way to break the task down into steps you can reason about.

I just had a terrible thought about a program and this seemed like the place.

For solutions to the halting problem that are input dependent, can't you answer based on an analysis of how it would handle input? Take for example recursive BST traversal. If it's not really a BST but instead has a cycle and you just keep on going forever, it won't halt - assuming infinite memory.

Why can't you answer "sure, assuming enough stack space and no cycles"? And what would stop static analysis from figuring this out without having to necessarily run it? I certainly don't have to run a program to see "oh a circular loop would run forever on this."

If this is too academic just point me in the right direction I guess.

You can't even write a program to definitively answer "will Program A run forever if given Input B?" in all cases.

That "in all cases" bit is basically the essence of the halting problem. Coming up with solutions for specific subcategories of programs can be interesting, but is kind if unrelated to the general problem.

# ? Jul 28, 2015 05:35

I guess I don't understand what "all cases" entails.

# ? Jul 28, 2015 06:25

Space Whale: Nov 6, 2014

Any possible program at all, yeah, that's intuitive.

What I'm asking about is how far can you go with a specific program, or a specific KIND of program, but that's a huge can of worms and I need to just read.

"All cases" means you want to find a general solution for all possible programs. We can prove that it's not possible to find a solution through contradiction:

- assume a program exists which solves the halting problem
- show that there is at least one program where the above does not give a correct answer

So, let's assume you've written a program which solves the halting problem. Well call this program H. H(A, B) means "does the program A halt when given the input B?".

Let's make a new program, call it G. G(A) is just H(A, A) - "does the program A halt when given itself as input?".

Let's make another new program - call it I. I looks like this:

code:

def I(A):
  if G(A):
    while(true):
      ;

That is to say, it runs forever if A halts, but halts if A runs forever.

So what's the result of I(I)?

i think i might have mentioned it in this thread before, but the Worst Interview Question of All Time is

quote:

find a non-empty string that can be constructed by concatenating the elements of each of two arrays of strings.

or formally,

quote:

given two arrays of strings A and B, find arrays of indices I and J such that

A[I[0]] + A[I[1]] + ... + A[I[N]] == B[J[0]] + B[J[1]] + ... + B[J[M]]

where (+) is concatenation.

this is the post correspondence problem and it is undecidable

that was me trying to come up with an informal description and failing. in hindsight, a better one would be

quote:

Suppose you're given two groups of words, A and B. Is there any non-empty sentence that can be made from A and also made from B?
