Long shot, but does anyone have an extra CCC ticket I could buy? Wasn’t able to get one in the open sales :/ I’d love to organize another hobby OS dev meetup and maybe do a small kernel dev workshop for anyone interested. Could also bring some merch to sell from shop.offlinemark.com ! 🙏

week 94, streaming kernel dev topic: physmap Working on some unit tests for the physmap physToVirt() and virtToPhys() functions today. Testing out LLM assisted unit test generation (Prerecorded since I'm away) see ya 👋 youtu.be/oXY1ylrW6GM

week 93, streaming kernel dev right now topic: virtual memory last week we finished the bitmap allocator, complete with unit tests. will continue on whatever's next, probably using that to allocate page tables and set up virtual memory see ya 👋 youtube.com/live/SO7x0Z...

week 82, streaming kernel dev right now topic: c++ STL last week we got c++ working in the cmake build. now that we have that working, continuing today with trying out some embedded/freestanding STL options see ya 👋 youtube.com/live/-ukB4U...

week 81, streaming kernel dev right now topic: lldb, c++, STL last week we got all the clang/llvm work ported over to cmake. will continue with using lldb instead of gdb, then moving on to c++ support (hopefully including some kind of STL to use) see ya 👋 youtube.com/live/lJRi_h...

week 80, streaming kernel dev right now topic: clang/c++ cmake last week we got limine integrated into cmake, will continue with porting the clang/c++ support I previously worked on, into cmake see ya 👋 youtube.com/live/jwvHrq...

week 66, streaming kernel dev right now topic: networking last week we finally got RX working and received network data into userspace. continuing with networking today and likely finish the networking lab see ya 👋 youtube.com/live/7X8WKy...

week 59, streaming kernel dev right now topic: network driver continuing with last week's work to get the nic initialized! see ya 👋 youtube.com/live/Gf6Y_Q...

week 57, streaming kernel dev right now topic: network/NIC driver after learning last week about qemu networking, today we're going to work on initializing the network card via PCI and accessing it via mmio see ya 👋 youtube.com/live/cFfENG...

week 56, streaming kernel dev right now topic: network driver starting the network driver, which is the final lab of the coursework I'm following (also, multi-streaming to twitch today for the first time) see ya 👋 youtube.com/live/j4o7Km...

week 54, streaming kernel dev topic: filesystem / process spawn streaming some filesystem dev and debugging, then moving onto start process spawning (prerecorded since i'm away today, back live next week - see ya 👋) www.youtube.com/watch?v=E0K...

week 55, streaming kernel dev right now topic: exec / spawn syscall now that we have a filesystem, we can try to exec programs from disk :) working on this today see ya 👋 youtube.com/live/-FeYOM...

week 53, streaming kernel dev right now topic: filesystem working on the core fs routines for walking the filesystem to find disk blocks see ya 👋 youtube.com/live/zTUK5f...

week 52! streaming kernel dev right now topic: continue hacking on the filesystem see ya 👋 youtube.com/live/3o-CYb...

week 51, streaming kernel dev right now topic: filesystem needed to debug some boot issues last week after merging in the new lab code; will actually start the filesystem work today see ya 👋 youtube.com/live/bNg7oQ...

week 50! streaming kernel dev right now topic: begin filesystem finished the multicore/fork/IPC labs last week, beginning filesystem work this week 🤠 see ya 👋 youtube.com/live/kVPJ95o...

week 49, streaming kernel dev right now topic: basic IPC working on a basic IPC system so processes can send messages between each other see ya 👋 youtube.com/live/35QuRw...

week 48, streaming kernel dev topic: debug final bugs with COW fork syscall debugging a subtle bug in my COW fork support: I didn't realize that the child will immediately fault in its stack when it gets execution after the fork (prerecorded since I'm at CCC!) youtu.be/ohT3ZHI4kRc

week 47, streaming kernel dev right now topic: preemptive multitasking very exciting! we've only had cooperative multitasking with explicit yields so far — now it's time to implement preemption with a timer interrupt see ya 👋 youtube.com/live/CfEJOB...

week 46, streaming kernel dev right now topic: copy on write fork() in userspace continuing with this now that I finally understand this "UVPT" recursive page table mechanism for mapping the page tables so they're accessible from userspace see ya 👋 youtube.com/live/ura43M...

week 45, streaming kernel dev right now topic: copy on write fork() in userspace now that we have userspace page fault handling working, we can proceed to the lab where we implement copy on write fork, entirely in userspace see ya 👋 youtube.com/live/PjsXpSu...

hit a milestone, 5000 subs on youtube 🤯 a heartfelt thank you to anyone who has joined, watched, commented, or supported my streams in any way 🙏 it's really wild how much you can learn by just practicing something for 2 hours a week, every week. next stop: 52 weeks of kernel dev 🌽 🤓

week 44, streaming kernel dev topic: userspace page fault handling prequel to week 43, worked on the kernel-mode syscall support behind userspace PF handling (incl. recursive page fault support) (pre-recorded since I'm away this week ✌️) https://www.youtube.com/watch?v=5fv6Pjx3in8

week 43, streaming kernel dev right now topic: userspace page fault handling making decent progress, will work on the assembly stub that returns control back to the user thread see ya 👋 #programming https://youtube.com/live/WcbInYfBAOQ?feature=share

hello world 👋 will start posting my hobby kernel development streams here (every sunday, 10am ET)
