New #blog post. Let's write a peephole optimizer for #QBE that operates on #AArch64 assembly code. Three years ago, we did this for #AMD64 assembly code. But now that I have Arm machines, we can replicate the effort for another CPU architecture.

Today is Monday, 1st September. And September means one thing: EuroBSDCon!

23 days to go until EuroBSDCon 2025 in Zagreb!

I’m doing a little “advent calendar” for BSD fans: each day until the conference I’ll share one article from it-notes.dragas.net about FreeBSD, OpenBSD, NetBSD, DragonFlyBSD, ZFS, PF and more. The dedicated hashtag will be #EuroBSDConAdvent

Let’s start right away with "I Solve Problems" - my EuroBSDCon 2024 (and #BSDCan 2025) talk about migrating from Linux to BSDs:

https://it-notes.dragas.net/2024/10/03/i-solve-problems-eurobsdcon/

If you’re coming to Zagreb, reply to this post - it would be nice to meet up with fellow BSD users!

⚠️ News/Changes:

BoxyBSD will bring in a feature for more advanced users for our free boxes. Instead of only selecting a set of pre-defined BSD based images, you'll soon also be able to create your install simply from scratch with full remote access to your box. This lets you perform custom installations of #FreeBSD, #NetBSD, #OpenBSD, #DragonflyBSD, #MidnightBSD but also of some other niche systems like #illumos

Unfortunately, this might still take some time and fully relies on the spare time of @gyptazy.

Two #blog posts in less than one week!

It was considered known that there is no support within GNAT (Ada) for illumos. We cross-build a complete native binutils+gcc toolchain for illumos to test out this claim.

...only to discover that illumos has full support within GNAT. Not a single test fails.
