pic.twitter.com/84ZKWJkZz1Use Git as a Database! On Monday I built the proof of concept. I've added to my (very ugly) website a newsletter signup form. And it works! I'll explain how in the first email going out 😉gunargessner.com
gunargessner.comNeed your help. I'm about to build a fully functional webapp in ClojureScript.
What should I build?.@paulbiggar just open sourced @darklang
github.com/darklang/dark
@paulbiggar@darklanggithub.com/darklang/darkAdded a strawman RSS feed to my website because requests gunargessner.com/rss.xml
gunargessner.com/rss.xmlIdea du jour. A Twitter bot. That tracks GitHub stars of a bunch of interesting projects. And tweets whenever one of them reaches a round number.
"The project X just got 1,000 GitHub⭐s."Solved a code challenge. Scheduling problem, to which I've applied Dijkstra's algorithm. Feel free to check out the solution! Clojure is so expressive that the code fits in one screen.
gunargessner.com/code-interview…
gunargessner.com/code-interview…Someone somewhere some time ago realized competitive programing was more fun than actual work and started playing it instead of getting things done and now we all have to pay the price.@zmillman Hey Zach, I'm Gunar. Nice to e-meet you. I'm doing some product research. And I've read your post from 2017 on interviewing software engineers using Mock Code Reviews. I'm wondering how that's going for you. How is it?
@zmillmanHere's a fun project. Use GitHub's API to crawl all repos. Extract their dependencies. Train an ML model and run the model against the repos. Then use the info to open PRs like "I see you're using chai. 90% of project which use chai also use chai-as-promised."The more I learn Clojure, the more I think "why again are we writing JavaScript?" It's not like someone is shipping handcrafted JS over the wire. It's all bundlers, compilers, and minifiers. Might was well write code in whatever language we're most productive.How convenient that @recoiljs has native features for most of the sam.js.org pattern:
(S)tate as pure functions = selector()
(A)ctions = setRecoilState()
(M)odel with an acceptor stage = selector({ set: acceptorFn })

I can barely believe I got the opportunity to watch a manned spaceship launch during my lifetime. Way to go! 🇺🇸At all times, strive to keep our surroundings inside the scope of our awareness.

Our inner child likes to "play code" with unnecessary refactors and fantastical abstractions.

@RoamResearch#feature_requestToo many of us Devs are business-averse. We just want to get specs, code, and clock out.
