If you are using Android and have an interest in RPN calculators, I highly recommend RpnCalc. No ads, no tracking, just a great calculator.

Filling out forms to get CI runners means no serious users will be attracted.

I think this will have opposite effect. Only serious users will be willing to fill out forms and casual users will be put off by the bureaucracy. I agree that it is a downside though. In a perfect world, there would be no forms to fill in.

The problem with CI is that the internet is full of not-nice people who will use free compute to mine crypto. Gitlab had problems with this abuse and requires credit card details.

I also use KeepassXC and Synthing together and I am very happy with this combination.

One tip that I have, if you are worried about the security of the database file being shared, is to get 2 Yubikeys and use these, along with a strong passphrase, to protect the database file.

At $work we write closed source Rust but we do not use Kellnr.

Instead we use a mono-repo, using a workspace, that contains most of our applications and libraries.

Our setup is mostly OK but needs some workarounds for problems we have hit:

• Slow cargo clean && cargo build, to speed this up we use sccache.
• Very slow Docker builds. To speed these up we use cargo chef.
• Slow CI/CD. To speed this up we use AWS instances as Github runners that we shutdown, but do not destroy, after use. This allows us to cache build dependencies for faster builds.

I am generally happy with our setup, but I am a fan of mono-repos. If it ever becomes to difficult to keep compiles times reasonable, I think that we would definitely look at Kellnr.

I enjoyed reading the Phoenix Project and learnt a lot from it. It is a classic for very good reasons.

There was another follow up book -- The DevOps Handbook that went into more detail about solutions to the problems raised in the Phoenix Project. I got a lot from the DevOps handbook but I found it quite a heavy read.

Years later I found a smaller, but super practical book, that covered much of the same subject matter -- Operations Anti-Patterns, Dev Ops Solutions. I recommend this Manning book after the Phoenix Project.

But then I haven't read the Unicorn Project yet, so that is a book for the list.

LOL, yes. Just in case it is of interest:

• ESP32-S3 is the chip, this family usually comes with CPU + Bluetooth + Wifi.
• Reverse TFT, this is a small display put on the other side of the circuit board from the chip.
• w.FL Antenna, this is the connector on the Wifi Antenna.

I like these small boards, they are tiny and I need a magnifying glass for soldering. Its mind blowing how these tiny boards are more powerful than mainframe computers filling a room, and supporting 20 users, used to be.

I think that Kreya is worth a mention:

• It has more complete OAuth2 support than Insomnia.
• Saves to human readable files.
• Usable free tier.
• Cheap Pro tier pricing.

Despite using Tokio underneath, I think that Actix does NOT do work stealing and uses mostly separate threads:

• https://actix.rs/docs/server/#multi-threading
• https://docs.rs/actix-rt/latest/actix_rt/

Given this architecture, I think the article might inaccurate when it says that Actix handlers must be Send + Sync. See also: https://www.reddit.com/r/rust/comments/14cbe1u/why_does_actixwebs_handler_not_require_send/

Actix is a bit weird, but it has been around, and used in production, for a relatively long time.

I am not sure if it is best practice, but this is what I do and it might provide some inspiration:

• Bootstrap from a private gitlab.com repository with a base ansible setup. Executed from a laptop.
• The bootstrap setups up k8s and installs a bare bones git repository docker container based on https://codeberg.org/al13nsc13nc3/gitsrv.
• Flux CD is installed into the bare bones git repository and k8s.
• Flux CD is used to install Forgejo and Woodpecker CI using the bare bones git repository as the gitops source of truth.

This has the advantage that Gitops and normal git repositories are separate. I think that a similar principle would work with docker compose instead of k8s.

The person that found this is a hero.

Whenever I see slightly weird behaviour, there is a temptation to just move on because there isn't enough time, running software is complicated, and there is something else I want to do. I will try to change my attitude in future in case it uncovers a backdoor like this -- it would be educational too.

I learnt something from this article, thanks.

I only found out yesterday that Rust has a Binary Heap in the standard library so the timing of this is perfect.
