My main authoring tool is then Emacs Markdown Mode (https://jblevins.org/projects/markdown-mode/). For data entry, it comes with some bells and whistles similar to org-mode, like C-c C-l for inserting links etc.
I seldom export my notes for external usage, but if it is the case, I use lowdown (https://kristaps.bsd.lv/lowdown/) which also comes with some nice output targets (among the more unusual are Groff and Terminal). Of cource pandoc (https://pandoc.org/) does a very good job here, too.
hey hn, supabase ceo her
we just announced GA, after ~4 years of beta. for those who don't know: supabase is a postgres hosting company. we also host other open source "backend" tools that make it easy to get started with postgres (tools like PostgREST for auto-generate APIs [0])
we owe a lot to the HN community. you launched us 4 years ago [1], when we were just a few developers. since then HN has been a staple in our journey, one of the best sources of product feedback [2]
the GA badge is mostly to signify organizational readiness. we're at a stage where we can take any profile of customer. we have a support team that works 24/7, and a success team that will help customers improve their postgres usage. we released our Index Advisor [3] yesterday, and we'll be releasing a few more products this week that helps customer with performance and security.
on a personal note: i read HN most days, and love going through the ShowHN's to see what devs are building. thanks for being an awesome community and my favorite place to lurk on the internet. i'll stick around to answer any questions

Short version: no type classes (yet)
Longer version:
Building upon what Quekid5 mentioned, Unison abilities are an implementation of what is referred to as algebraic effects in programming language literature. They represent capabilities like IO, state, exceptions, etc. They aren't really a replacement for type classes, though in some cases you can shoehorn abilities in where you might otherwise use a type class.
For someone coming from a Haskell background, I think that abilities are closer to a replacement for monad transformers. But in my opinion they are much more ergonomic.
Discusson of type classes comes up a lot. Here is a long-standing GitHub issue: https://github.com/unisonweb/unison/issues/502
For what it's worth, I've written Unison quite a lot over the past few years and while I've missed type classes at times, I think that reading unfamiliar code is easier without them. There's no implicit magic; you can see exactly what is being passed into a function. So far I've been happy with a bit more verbosity for the sake of readability.
Project mention: What are your favorite End-to-End encrypted tools for online privacy? | /r/degoogle | 2023-12-08For messaging I'm currently on Olvid (E2E with physical key exchange) but since it still use their servers, I'm currently testing SimpleX where I can host my own servers.
The official guide and the archwiki do say that it's okay to just install it via pacman, but I've also found some issues on the official repo that strongly suggest against installing via pacman and to use stack instead, as sometimes pacman breaks dependencies.
I'm surprised that there is no mentions of a great hacker-friendly plain-text accounting software called `ledger` https://ledger-cli.org/ in this thread. It has amazing documentation when it comes to understanding basic principles of double-entry bookkeeping and goes through many typical situations and usecases. There are also several forks, most popular and advanced is `hledger` https://hledger.org/ (h is for Haskell), which provides some neat features out of the box, such as a simple web interface. All of them are very primitive compared to "professional" accounting software, but in return it offers great opportunities for hacking around while ensuring validity of your books.
Or just go full on functional. There are several JVM based Haskell languages, e.g. Eta and Frege.
The advent of language server protocol made possible the creation of HLS (Haskell Language Server), and there are plugins for many editors, such as vscode-haskell, that allow you to have auto-complete, auto-import, and automatic function signatures—also available to your editor of choice. The whole feedback loop of editing, compiling, and running is greatly improved.
> do you really have to understand language extensions?
You do when your code doesn't compile and you're trying to figure out what the error message means, or when the library you want to use makes heavy use of it for even basic functionality.
> These days one just enables GHC2021
My experience was pre-GHC2021. I basically had to enable at a minimum 5-6 language extensions in every single file.
> Mostly they're just about removing unnecessary restrictions from the older standard.
Yeah, those ones are usually fine. I have zero objection to things like FlexibleInstances or DeriveFoldable.
> Could you give an example?
I believe I was trying to implement Central Authentication Service using Servant. However, that required returning a custom HTTP status code. There has been an open Github issue for this since 2017, but it seems to require basically rewriting the entire framework: https://github.com/haskell-servant/servant/issues/732
Looking back at it now Servant does have "ServerError", but that basically requires giving up all the advantages Servant claims to have and I believe it was not a viable option at the time. Looking at the timeline I was probably also on Servant 0.15, and there seems to have been a rewrite since then.
I vaguely recall running into a similar issue trying to interact with a database, but I can't remember the details of that.
Project mention: Show HN: Text Lambda, a versatile notebook for your personal data | news.ycombinator.com | 2024-02-21Thank you!
"stash", the initial MVP version, is written in Haskell. I chose Haskell mostly because of https://github.com/jtdaugherty/brick, which is a wonderful TUI library. I also tend to prefer functional programming languages when I have the choice.
However, Text 's backend and website are currently implemented in Clojure. The app is in C + Flutter (Dart).
