Question: what is best way to convert double to string. If I use libc's sprintf I'd still need to know output length so I think best way is to roll my own
Make numbers inflate to full width! code-golfstring
Related: Full Width Text
That is a challenge that changes ALL characters into full width -- BY ADDING A SPACE AFTER EACH CHARACTER. However, in this challenge only numbers are transformed, and are transform to the REAL FULL WIDTH FORM

i like it that this library prints floats with enough precision so they round trip - if you type back the formatted float in your interpreter, you get the exact same bits
Help Runbee manage the pollen! [better title needed?]
The arsonist friendly bee, Runbee, just finished picking up the pollen from the flower garden and now she wants to store it safely in her hive. Each pollen type is labeled with a digit (from 1 to 9). Runbee's "collection" is stored in a row...
Write a fully modular C program that reads in a string of a defined size from the keyboard and reports how many times each letter of the alphabet occurs within that string (ignoring case). It should also report how many non-letters are included in the string.
Coprimes upto N (Performance Edition)
There is this question: Coprimes up to N
Most of the answers there take way to long for larger numbers.
So, your task is to find all the coprimes of a number n (gcd(n,coprime)==1) up to nas fast as possible.
Scoring
Score=Largest n for which your code w...
Sort a list, poorly
code-challenge array-manipulation
Don't you hate it when you're trying to roughly sort a list based on user data, but you have to poll the user for thousands of comparisons?
Hate no more, because the answers to this challenge are (going to be) here!

Fully modular C program
Modularity means that instead of writing one big long procedure, we break up our logic into small, composable functions. We all know that modularity is a good thing. But why settle for a good thing when you can have the best thing? Let's make our programs fully modular. ...
Do we have any popularity-contest challenge related to syntax abuse/obfuscation? Sometimes when a friend of mine proclaim that Python has the cleanest syntax and is always intuitive, I send them something like l=lambda l:l(**{'l':l});l(l) and we share a laugh. However I always enjoy scripts where you just say "how on earth does that even compile/work?" regardless of language
I'm in the market for an external hard drive, and it's really hard to get any real data on their reliability
The best source is Backblaze, but they mostly use commercial grade drives (meaning no covering). They also don't have much data on Western Digital (one of the 2 leading brands)
amazon customer reviews are terrible because both sides are saying "unreliable" and "has terrible customer service"
@NathanMerrill I used a Seagate 1TB Backup Plus external USB drive from 2013 until spring of this year when it kicked the bucket, and now I use a Seagate 3TB Expansion Portable USB drive. I could've got the 4TB one for only an extra $10, but the 3TB one was available next day.
While my 1TB drive did die after 5 years of regular (almost daily) use, I'd still definitely recommend Seagate's external USB drives. Really no matter what external drive you get, you shouldn't entirely rely on it for data safety, and should have other backups just in case. I use Backblaze to back up my 3TB drive these days
