Address Randomization Tribulations — So, I have a tiny 32-bit application (a Forth) taking up about 4K, written in fasm. Pure minimalism, including an iffy elf header that fasm creates, with a fixed load address. More on that later. It's been unstable, and I tracked the instability down to the initial memory allocation. Right at the start I add my desired memory size to the code base (the top label in asm code), and invoke `brk` system call. This worked as long as I allocated a largish...

binary file reported as 'no such file or directory' upon execution — This has to be the weirdest behavior ever. A small utility that works fine on my main machine was copied over to my Thinkpad, running identical XUbuntu. Fails on ThinkPad only I can ls it, permissions are fine, even HD and objdump look reasonable. When I try to invoke it from command line, bash reports that it does not exist. strace shows execve with correct path, craps with ENOENT (no such file or directory) It's like it...

XDG, default apps, mess... — I am having way too much trouble doing something very simple. I have two machines with XUbuntu but dwm'ed. I want to be able to look at files. I started with PCManFM (from inertia), and using xdg-mime configured text/plain to open vim.desktop (5Kb of yuck!). On one box it works, on the other it opens vim in a 80x24 space, after which status text gets printed at the bottom, arrows scroll past the editable 80x24 region, and the whole thing is a mess, although in a...

I used to love distro-hopping, but for the last couple of years I've been so satisfied with Arch that I haven't been trying anything else. This morning one of my PCs needed a new OS because of power issues. I was shopping around, tried NixOS since people have been talking about it lately. I even booted into Manjaro since it's basically Arch anyway. But then I finally installed plain old Arch and it's just what I want. 🤷 It's nice to find something I'm happy with, but I did enjoy...

Did anyone else get a Beepy, aka Beepberry? — I just got one a few days ago and it's pretty cool. Kind of like a smaller PocketCHIP. I'm using a Pi Zero W in it for now because I already had a few on hand but would like to try the RISC V MangoPi MQ Pro eventually. I wrote up some first impressions on my gemlog.

Posting this from Amfora running on a linux distro contained entirely within the kernel image, bit hacky but it works

Anybody have useful git aliases they would like to share? One that really helps me that I've defined is `co = !git checkout "$(git branch -a | fzf)"`. This lets me type `git co`, pick a branch interactively from the list, which then checks out that branch. (I know if I properly set up shell completions I'd get suggested branch names by hitting tab, but the fuzzy search behavior from fzf is really nice.)

Question: How do I compile the Linux kernel? — By which I mean, what compiler flags, options and configs should I look out for, such that my kernel will actually succesfully run? I am talking about QEMU without KVM as the platform.
