DuckDB as the New jq

While it doesn’t provide an SQL interface, I’ve been using Nushell as my shell, which has native data operations. I tried querying the same, and I’m still not fluent (this was my third or fourth bigger/practical data querying), but it works well and fast too when you know the syntax: http get https://api.github.com/orgs/golang/repos | each {|x| get license} | get key | group-by --to-table | update items {|x| $x.items | length } I’ve used Nushell for reading en-mass json files, generating command json files for stuff saved in excel files (you can natively open those too), and most recently to query log files for specific information and usage analysis. /edit: This comment has the better nu solution.

Beginner resources?

I assume you have already tried the official tutorials, but Go By Example is a great “learn by doing” kind of tutorial. Others that I found in a quick DDG search: https://www.w3schools.com/go/index.php - a very simple introductory tutorial https://www.learn-golang.org/ - an interesting tutorial that lets you run exercises in your browser https://go.dev/tour/list - a similar interactive tour

We're looking for GoLang Contributors

Yes, the about site needs a lot of work. The demo site is using the Lemmy frontend but Java Springboot backend. The whole intent of the first milestone release is to be a drop-in replacement for Lemmy. It’s after that where we will differentiate with things like better moderation/admin support, etc… The federation service will be built in Golang. And yeah, we need to do a lot more work on outlining what work needs to be completed in the form of issues. Those 8 for sure are things that need to be done though.

A Rant about Front-end Development

I signed up to this instance because I feel this in my bones. I cut my teeth on PHP CGI in the late 00’s before shifting to python CGI because my university had banned PHP on the webservers. Frontend wasn’t exactly a term back then. I’d picked up a bit of jquery into my server generated Django templates, I was playing with template fragments in 2011 and life was good. I mostly avoided the SPA fad, but a (short) stint at Wayfair had me end up writing react and dear God the amount of indirection and tomfoolery involved with effectively writing the app a second time left a sour taste in my mouth. These days I mostly write embedded daemons in rust for Linux devices. I wrote a munin replacement in rust because packaging perl for Yocto is a struggle. I needed to serve a website, so I found a jinja style library, setup my templates and fragments and dropped htmx into the frontend. Life is good again. I have friends/coworkers who argue with me that I should write SPAs but they don’t get that I mostly want to avoid fighting frontend tooling and get shit done. A backend serving templates is miles more ergo than react and I don’t have to deal with the NPM upgrade treadmill. I don’t get daily dependabot alerts. Don’t get me started on golang, meteorjs, and lambdas

I like C programs for their speed

I was a huge C++ fan back when I was doing a bunch of competitive programming. If I need a performant project nowadays, I look to golang first. It gives me the speed of a compiled language with the usability of high-level language. I still solve the occasional Advent of Code in C++, though :)

Advent Of Code 2024

I wasn’t able to complete last year’s AoC as I am 10+ hours ahead and I am a bit daft. Hoping to do this year’s AoC in a new language so I can practice. Thinking Zig, Golang or Rust.

[ On | No ] syntactic support for error handling

The lesson learned (in my opinion) is that if you’re going to design a language where errors need to be handled explicitly, you need to design the language from the ground up to support monadic error handling syntax. At this point, it seems too late to add it to Golang. What a shame - it could have been so much better of a language without this flaw.
