Fly, you tools - Piotr Szotkowski

As developers we heavily depend on our tools of the trade, as oftentimes mastering them means getting out of deep trouble so much faster.

This talk covers some lesser known features of our everyday infrastructure : Git, PostgreSQL and command-line; tricks which make using these tools such a pleasure, regardless whether it’s for shaving yet another yak or saving one’s own skin.

4. talk assumptions you know there are nifty things you can do with tools you’ve seen some blog posts describing various tools in excruciating detail you can’t remember 90% of any given post the day after, including that one useful trick it would be cool if someone shared small and crucial bits that are actually useful every day especially if they are not well­known
5. tools Git PostgreSQL Vim command­line tools (just kidding)
6. Git What you must understand is that Git is a sharp knife and the handle is also a knife, and each side contains more knives, fractally. — Brandon Hays Git gets easier once you get the basic idea that branches are homeomorphic endofunctors mapping submanifolds of a Hilbert space. — Isaac Wolkerstorfer
7. Want to make a Git repository behave strangely every now and then? Have a coworker that creates a remote branch called HEAD. — Patrick Hüsler git checkout -b noʎ_ʞɔnɟ — William Morgan I didn’t expect g i t c o m m i t - - a m e n to work, but to quote Leonard Cohen, hallelujah. — chromatic Just discovered g i t r e b a s e - - i n t e r a c t i v e - - a u t o s q u a s h . Holy shit. Will never again need to do any work. — Tom Stuart

15. PostgreSQL I believe that if Postgres had a catchy name (say, SuperSQL) it would have left MySQL in the dust long ago. — Diego Basch Though incorrect, PostgreSQL is more fun to use when you pronounce it as ‘post-Grayskull’. — karlinfox Want to fall in love with PostgreSQL by reading just one page of the documentation?
