Thanks, jgrim

After asking for a first programming language here, I've decided learning Go. After some searching I've found that the beginner learning resources are some years old. Can anyone suggest some beginner resources for someone that likes to learn by doing stuff? Thank you.

go1.22.2 (released 2024-04-03) includes a security fix to the net/http package, as well as bug fixes to the compiler, the go command, the linker, and the encoding/gob, go/types, net/http, and runtime/trace packages. See the Go 1.22.2 milestone on our issue tracker for details.

Rook, a secret service backed by Keepass 4.x kdbx

Howdy Lemmy,

I'm announcing Rook v0.0.9, software that provides a secret service a-la secret-tool, keyring, or pass/gopass, except backed by a Keepass 4.x kdbx file.

The problem Rook solves is mainly in script automation, where you have aerc, offlineimap, isync, vdirsyncer, msmtp, restic, or any other cron jobs that need passwords and which are often configured to fetch these passwords from a secret service with a CLI tool. Unlike existing solutions, Rook is headless and does not have a bespoke secrets database, full of passwords that must be manually synchronized with Keepass; instead, it uses a Keepass db directly.

While the readme goes into more detail, I will say the motivation for Rook evolved from a desire to use a Keepass db in a GUI-less environment and finding no existing solutions. KeepassXC provides a secret service, but is not headless; it also provides a CLI tool, but this requires the db credentials on every call. kpmenu exists, but is designed specifically to require human interaction and is unsuitable for cron environment scripting. Every other solution maintains its own DB back end, incompatible with Keepass.

Rook also benefits from minimal external dependencies, and at 1kloc is auditable by developers - I believe even by ones who do not know Go (the language of implementation). Being able to verify for yourself that there's no malicious code is a critical trait for a tool with which you're trusting secrets.

Rook is fit for purpose, and signed binaries are provided as well as build-from-source instructions (for auditors).

The project contains work in progress: credentials are limited to simple password-locked kdbx, and so doesn't yet support key files. Bash scripts that provide autotyping and attribute/secret selection via rofi, fzf, and xdotool are provided, for GUI environments; these have known bugs. Rook has not been tested on BSD, Darwin, or any other system than Linux, but may well work; the main sticking point is the use of a local file socket for client/server communication, so POSIX systems should be fine, but still, YMMV.

As a final caveat: up until v0.0.9 I've been compressing with brotli, which is very nice yet somewhat obscure. With the next release, everything will be gzipped. Also included in the next release will be packages for various distributions.

Sometime around the middle of January, I stumbled across One Billion Rows Challenge. I had a lot of fun working on this. I started with an execution time of > 6min and finished at about 14s. Here’s how I went about it.

I've seen that a new "range-over-func" experiment is available with Go 1.22. In this article, I took a closer look and evaluated the feature for myself.
