I am too bored and want a challenge to solve. But I do not see any interesting challenges, and I am too lazy to search for one. Can you (Well, technically your code) suggest me one?


Input: None.

Output: A link to a random open(i.e. non-closed) challenge("Challenge" excludes !) on PPCG. You may not link to an answer in a challenge, Just a challenge. (I didn't ask for an interesting answer!)

  • \$\begingroup\$ Can we output http://codegolf.stackexchange.com/questions/93288/ instead of http://codegolf.stackexchange.com/questions/93288/make-me-a-mooncake (note the lack of challenge name). \$\endgroup\$ – user41805 Mar 26 '17 at 11:53
  • \$\begingroup\$ @Kritixi Lithos Sure, that works. \$\endgroup\$ – Matthew Roh Mar 26 '17 at 11:54
  • \$\begingroup\$ Not all tips questions have the word "tips" in their name. See this one for example. Is that allowed or did you mean to remove challenges in the "tips" tag? \$\endgroup\$ – seshoumara Mar 26 '17 at 12:11
  • \$\begingroup\$ @seshoumara The latter, that's also the reason I typed 'tips' as a tag. \$\endgroup\$ – Matthew Roh Mar 26 '17 at 12:12
  • \$\begingroup\$ There are about 6k questions fulfilling your criteria on PPCG. Do all need to have a chance of being picked by random, or can I pick at random from the first 50 results I get from a search link? \$\endgroup\$ – seshoumara Mar 26 '17 at 12:21

JavaScript (ES6), 209 bytes

Does work, but will most likely hit the StackExchange API limit very quickly. It will probably take a while to output the link, as it's checking randomly for a valid question.

_=>fetch(`//api.stackexchange.com/2.2/questions/${new Date%2e4}?site=codegolf`).then(_=>_.json()).then((a,b=a.items)=>{if(!b.length||b[0].tags.includes`tips`||b[0].closed_date)f();else console.log(b[0].link)})

f=_=>fetch(`//api.stackexchange.com/2.2/questions/${new Date%2e4}?site=codegolf`).then(_=>_.json()).then((a,b=a.items)=>{if(!b.length||b[0].tags.includes`tips`||b[0].closed_date)f();else console.log(b[0].link)})


  • \$\begingroup\$ The OP said that all questions fitting the requirements need to have a chance of being chosen at random. \$\endgroup\$ – seshoumara Mar 27 '17 at 12:31
  • \$\begingroup\$ @seshoumara should be fixed now. \$\endgroup\$ – Tom Mar 27 '17 at 13:06
  • \$\begingroup\$ Save 4 bytes by dropping the API version from the URL. \$\endgroup\$ – Shaggy Apr 25 '17 at 16:18
  • \$\begingroup\$ Got codegolf.stackexchange.com/questions/173/… which is not valid \$\endgroup\$ – sergiol Jul 25 '17 at 22:29
  • \$\begingroup\$ Can confirm that this generates tips challenges too... \$\endgroup\$ – FlipTack Dec 29 '17 at 13:47

Python 3, 452 339 bytes

from requests import*
from random import*
while 1:
    if r["items"]:
        if "tips" not in m["tags"]:

A bit unsightly and not very golf-y, but I couldn't figure out a better way to do it. Since this more or less brute-forces the API, you'll spend up your quota quite quickly and start getting errors, but after a few hours it'll work again.

EDIT: Saved 113 bytes by removing multiple unnecessary things, thanks to NoOneIsHere.

  • \$\begingroup\$ You only use l once, so it is unnecessary. \$\endgroup\$ – NoOneIsHere Jul 23 '17 at 4:31
  • \$\begingroup\$ That's correct. I did that so I could print the link afterwards if it was valid, but that printed the API link instead of the normal one. Thanks for reminding me. \$\endgroup\$ – LyricLy Jul 23 '17 at 4:37
  • \$\begingroup\$ Also, you can online the try and maybe the except. \$\endgroup\$ – NoOneIsHere Jul 23 '17 at 4:38
  • \$\begingroup\$ That is also correct. Thanks again. \$\endgroup\$ – LyricLy Jul 23 '17 at 4:43
  • \$\begingroup\$ Glad to help. Pad \$\endgroup\$ – NoOneIsHere Jul 23 '17 at 4:49

SEDE SQL: 79 bytes

Select Id from posts where ClosedDate IS NULL AND Tags !='tips' ORDER BY RAND()

There are 2 catches. One you have to wait for a while before running again or you have a cache hit (as a mod told me) and you only get the question id number.

  • \$\begingroup\$ I think it is valid because I am not that lazy to not even being able to type \$\endgroup\$ – Matthew Roh Mar 27 '17 at 22:52
  • \$\begingroup\$ Yes! Your word is lay on your challenge \$\endgroup\$ – Christopher Mar 27 '17 at 23:51
