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 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 4 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 .

Startup founder: "We're disrupting healthcare! Join our mission!" Engineer: "I checked Crunchbase and my salary exceeds your entire funding round." The beautiful transparency of tech compensation data strikes again! Thanks to sites like Crunchbase (and indirectly to Zuckerberg's social networking revolution), engineers can now instantly verify if your "world-changing startup" can actually afford competitive compensation. No more trading actual money for equity in your "revolutionary" idea that's basically "Uber for bandaids." Pre-seed doesn't pay the bills, but FAANG salary certainly does!

Ah, the eternal civil war among programmers trying to get the size of something. Is it count() ? size() ? length ? sizeof() ? len() ? Every damn language and library decided to pick their own favorite, and now we're all just Spider-Men pointing at each other in confusion. Nothing says "I'm a seasoned developer" like muscle memory making you type the wrong size function in every language and then cursing under your breath when the IDE throws a red squiggly line. Consistency? In programming? That's a good joke!
