For converting HTTP URLs into interactive images of the webpage.

In other words: an internet browser.

Because some auth provider recommended it as the only app to use. While it is a good app, it does backup into Drive.

Is this useful if I am using pi coding agent? It can swicth between models mid session?

New comment by aerzen in "Moving from GitHub to Codeberg, for lazy people"

Forgejo is also OSS, so you can easily migrate git and issues and prs and everything to your own hosted instance, if codeberg proves untrustworthy. Which I can't on github.

New comment by aerzen in "Google details new 24-hour process to sideload unverified Android apps"

aerzen — Sat, 21 Mar 2026 07:16:21 +0000

Could the title say "process to install non-curated Android apps"? "Sideload" and "unverified" imply that the collection of centrally approved apps is the default way to install software.

Or maybe it is and android's promises about openness are dead.

Why does JOIN get the prefix then? Is it a command? I would assume that it is a GET clause.

The `:` prefix is an interesting choice. I don't fully understand when it is needed. It seems to always be used at the beginning of the query. But why is it not used before WHERE?

New comment by aerzen in "Apache Arrow is 10 years old"

aerzen — Thu, 12 Feb 2026 18:24:35 +0000

I like arrow for its type system. It's efficient, complete and does not have "infinite precision decimals". Considering Postgres's decimal encoding, using i256 as the backing type is so much saner approach.

Yea, I have this too. It sometimes reminds me about the thing I was doing before I got distracted.

New comment by aerzen in "Tauri"

aerzen — Mon, 09 Feb 2026 06:21:34 +0000

I wanted to try tauri out, but i couldn't get the nix dev shell for it working. My suspicion was that they do something too magical with the build process.

New comment by aerzen in "uLauncher"

aerzen — Sun, 08 Feb 2026 10:15:57 +0000

My launcher of last 8years: Lawndesk. It's not on play store and you have to download it from github, but it is the only no-nonsens launcher on android without a drawer.

I just want a grid of apps, each of which appears exactly once. And then folders, to keep things on known locations

aerzen — Fri, 06 Feb 2026 20:16:51 +0000

Nice. My gripe with designer apps is that they are online first. I'd want to save designs to files, close to other files of the project. I'd want to open each file in their own window, not in browser tabs.

Sorry for being dismissive. I've written a post [1] that highlights the core discrepancy between the two dialects. I like criticizing SQL and having a documented case like this is nice.

This is a really long article for saying "precedence between || and + is different between PostgreSQL and Oracle SQL".

aerzen — Mon, 12 Jan 2026 12:23:26 +0000

A good idea in theory. When I was at uni, i designed a protocol for that, with the vision of having individual stores, "commerce article aggregators", and user apps that can query either stores directly or aggregators, all using the same interface, same user preferences and filters.

New comment by aerzen in "Elo – A data expression language which compiles to JavaScript, Ruby, and SQL"

aerzen — Mon, 12 Jan 2026 12:12:43 +0000

This is very similar to what I'm building: https://lutra-lang.org

The base premise is the same: SQL is not a proper programming language and everyone knows it only because they have to. And I feel like everyone who knows SQL enough admits that, but still none of the 20+ attempts of a better language stuck on.

As someone would say: sad.

Because we already have databases we have to query and they speak only a dialect of SQL. If there were a lower-level machine-friendly instruction set for databases, it should target that.
