Crying All The Way To The Bank

The eternal Windows USB ejection saga continues! That dialog box where Windows claims your device is "in use" but refuses to tell you what is using it is the digital equivalent of saying "there's a problem" without offering any solutions. The suggested button would skip the detective work of hunting down phantom file handles and just command whatever process to release its death grip on your USB drive. It's the command-line equivalent of sudo but for impatient Windows users who just want their flash drive back without rebooting their entire system.

Wow, shuf is sooo fast. - picking 10000 random lines from a textile with 40000 lines is instant. Trying to use 'sort -R' took so long I just CTRL-C it - carpii Jul 3 '15 at 20:10 2 1 If you just need a random set of lines, not in a random order, then shuf is very inefficient (for big file): better is to do reservoir sampling, as in this answer. - petrelharp Sep 6 '15 at 23:24 neither shuf nor sort -R are available for mac OSX. any suggestions? - Tom Smith Oct 6 '15 at 10:06 33 TomSmith On Mac OSX, if you are using Homebrew, you can get shuf or GNU sort by installing coreutils .

THE HORROR! THE ABSOLUTE TRAGEDY! Someone's marketing team just discovered why camelCase and proper spacing are the HOLY GRAIL of programming! The hashtag #SUSANALBUMPARTY was supposed to celebrate Susan Boyle's album release, but instead created the most catastrophic parsing error in social media history! This is what happens when you skip the code review, people! The difference between SusanAlbumParty and SusAnalBumParty is literally just proper capitalization standing between a music celebration and... something ENTIRELY different. Spaces and camelCase would have saved lives here, but nooo, hashtags don't allow spaces and someone skipped Naming Conventions 101. This is why developers drink.

The evolution of gender symbols reaches its final form: the USB trident. Because nothing says "programmer" quite like having three different orientations to try before you finally get it in correctly. The traditional male and female symbols are simple and straightforward, but programmers? We need maximum complexity with multiple connection points, backwards compatibility issues, and at least a 50% chance of getting it wrong on the first attempt. The USB symbol is basically the programmer's spirit animal—universal, essential, yet somehow always requiring at least two flips before it works.
