My mate and I went on a hike earlier. Yesterday, we had lovely 12Ā°C. But today, it was down to at most 4Ā°C. Oh well. At least the sun was out and and there was just a tiny bit of wind. We knew upfont that scarf, beanie and gloves were mandatory. Especially at the more windy sections like up top the hills. The view was absolutely terrible, but we made the best of it.

With the sun shining on us during our lunch break at a forest edge bench, we still enjoyed the lookout in 01. I brought some old carpet scraps to sit on and was happily surprised that they isolated even better than I had hoped for. Some hot tea helped us staying warm.

After five hours we returned just after sunset. Iā€™m quite tired now, completely out of shape.

So, are you guys up for an experiment?

Iā€™m really not happy with the domain ā€œuninformativ.deā€ anymore. Iā€™m going to switch to ā€œmovq.deā€ soon (or maybe something else if I get another fancy idea).

If I keep the url = field in my twtxt file, nothing should break, right? Right? šŸ¤£

(#qpsyz6q) Wow, as I anticipated, this is waaay out of my capabilities to really understand it. But Iā€™m quite happy to just have spotted a mistake in an explanatory comment in section 4.5.2 ā€œThe icode Arrayā€. Of course, it should be /e + tc + /i + ni + t\0. Letā€™s hope that my e-mail with the patch actually makes it into Briamā€™s inbox. I fear GMail just hides it in the spam folder.

(#hddm6pa) @prologic@twtxt.net Iā€™d love to take a look at the code. šŸ˜…

Iā€™m kind of curious to know how much Assembly I need vs. How much of a microkernel can I build purely in Mu (Āµ)? šŸ¤”

Canā€™t really answer that, because I only made a working kernel for 16-bit real mode yet. That is 99% C, though, only syscall entry points are Assembly. (The OpenWatcom compiler provides C wrappers for triggering software interrupts, which makes things easier.)

But in long mode? No idea yet. šŸ˜… At least changing the page tables will require a tiny little bit of Assembly.

(#hddm6pa) Iā€™ve only got a handful of syscalls working right now. Taking inspiration from the calling convention of the Linux kernel and even made the service/interrupt handler int 0x80h šŸ¤£ Iā€™ve only got read, write, alloc and exit working righ tnow šŸ„²

(#hddm6pa) Whohoo! šŸ„³ You have no idea how great a feeling this is! This includes the Mu stdlib and runtime as well, not just some simple stupid program, this means a significant portion of the runtime and stdlib ā€œjust worksā€ā„¢ šŸ¤£

Btw @movq@www.uninformativ.de youā€™ve inspired me to try and have a good ā€˜ol crack at writing a bootloader, stage1 and customer microkernel (ĀµKernel) that will eventually load up a Mu (Āµ) program and run it! šŸ¤£ I will teach Mu (Āµ) to have a ./bin/mu -B -o ... -p muos/amd64 ... target.

Took me nearly all week (in my spare time), but Mu (Āµ) finally officially support linux/amd64 šŸ„³ I completely refactored the native code backend and borrowed a lot of the structure from another project called wazero (the zero dependency Go WASM runtime/compiler). This is amazing stuff because now Mu (Āµ) runs in more places natively, as well as running everywhere Go runs via the bytecode VM interpreter šŸ¤ž

(#mqvmwva) @bender@twtxt.net Iā€™m already using it for tracktivity (meant for tracking activities and events, like weather, food consumption, stuff like that), which is basically a somewhat-fancy CSV editor:

I have a couple of other projects where I could use it, because they are plain curses at the moment. Like, one of them has an ā€œedit boxā€, but you canā€™t enter Unicode, because it was too complicated. That would benefit from the framework.

Either way, itā€™s the most satisfying project in a long time and Iā€™m learning a ton of stuff.

(#4b4ypwa) @lyse@lyse.isobeef.org Unix terminals are quite limited in that regard. šŸ«¤ You know how Ctrl works? The XOR 0x40 thing? And Alt doesnā€™t exist at all, itā€™s just a prefixed ESC byte.

I was surprised to see curses knowing about ā€œShift+Tabā€, wondering how that is supposed to work. Well, itā€™s an escape sequence, of course (depending on the terminal, of course).

Here am I looking at the different tcell.Key constants and typing different key combinations in the terminal to see the generated tcell.EventKeys in the debug log. Until I pressed Ctrl+Alt+Backspaceā€¦ :-D Yep, suddenly there went my Xā€¦

So far, it appears as if I can have either only Ctrl or Alt as modifiers. But not in combination. And Shift is just never ever set at all. Interesting.

This week, Mu (Āµ) get s bit more serious and starts to refactor the native backend (a lot). Soonā„¢ we will support darwin/arm64, linux/arm64 and linux/amd64 (Yes, other forms of BSD will come!) ā€“ Mu (Āµ) also last week grew concurrency support too! šŸ¤£
