Today I found out that instead of resolving your merge conflicts in your text editor, you can just accept all of the outgoing or incoming changes using one of these commands: ``` git pull -X ours/theirs ... # or git merge --strategy-option ours/theirs ``` #git #dev
GeekORM v0.10.0 has been released! Take a look at the changes as this has a major breaking change github.com/42ByteLabs/gee… #rust #rustlang
Streaming live now! Come say hi twitch.tv/geekmasher
I'll be streaming in a few hours tonight. Writing some #rustlang for my ORM and hopefully updating Konarr.
A week of work has paid off and GeekORM v0.9.0 is out! Added support for automatic migrations via the CLI and some other features. Checkout the full details here: github.com/42ByteLabs/gee… #rustlang #geekorm
First stream of the year, come say hi! Writing some #rust btw twitch.tv/geekmasher
Released v0.3 of Konarr today to celebrate the New Year. Massive improvements including continuous scanning of container images and better management of alerts. github.com/42ByteLabs/kon…
I wrote up a blog post on my talk from last night at Defcon Edinburgh @DC44131 called 'Konarr: A Story of Building a Software Composition Analysis Platform'. geekmasher.dev/talks/2024-12-… #cybersecurity #appsec #containersecurity
Triggered... I have not had WiFi issues in years but audio issues are a real thing #skillissue

Amazing to see we have 11 stars for #GeekORM ! Written in #rustlang btw. github.com/42ByteLabs/gee…
regex in kernel code should be illegal
Last night I thought to myself "How could I make it possible to write a GitHub App in Rust..." and a few hours later, we have a new OSS Project! crates.io/crates/octoapp #github #rust #rustlang
Every year is the year of the Linux Desktop!
