First mount/umount of #HAMMER2 on #OpenBSD A series of screencasts of hammer2 commands in OpenBSD, exploring everyday situations. Today we'll cover mount and umount. Soon I will publish a video (~6 min) applying a kernel patch + userland to get to the point in this video.

#OpenBSD back to 2011 #Bluetooth another step completed LESC (LE Secure Connections) with ECDH P-256 😰😰 working. Turn off the sound, construction in the background. www.bluetooth.com/wp-content/u...

Now we have a starting point #hammer2 #FFS #OpenBSD and FFS won the first match. Perhaps lists.dragonflybsd.org/pipermail/co... XOP (executable operation) github.com/kusumi/openb... doesn't appear to have

Spent the evening chasing a #HAMMER2 bug on #OpenBSD every mtime stuck at "31-12-1969". Not epoch zero the on-disk field is µs since 1970, but the kernel wrote seconds microtime(9) gettime() rt a count of sec *t = (uint64_t)ts.tv_sec * 1000000ULL + ts.tv_nsec / 1000; github.com/kusumi/openb...

OpenBSD on Firecracker. 1.4 MB kernel, ~30 ms cold boot, no BIOS, no PCI, virtio-mmio only. Experimental port. Wrote up how to build the kernel, prep an FFS2 disk with vnd(4), and boot the thing from Linux. ijanc.org/posts/openbs... Commit: git.sr.ht/~ijanc/openb...

Wacom Intuos S (usb tablets) on OpenBSD. uwacom(4) see everything pen, pad, pressure levels but Xenocara ships no Wacom driver though, so it ends up as a fancy mouse. PS: you now get to endure my "artistic skills". Irony included 😇 ijanc.org/posts/wacom-...

As I always say! Baby step 👼

i've been testing bt on an obsd snapshot ThinkPad X1 Nano, mainly for mouse/keyb use, is just for personal use. The learning experience has been incredible the OpenBSD codebase is exceptionally clean and insightful. HID (mouse/keyb) is still not reliable enough for daily use. #OpenBSD #bluetooth

Privilege separation in Tesseras! 5 isolated processes OpenBSD-style (relayd(8)): parent supervises net, dns, http and control via Unix socketpairs. Each child with seccomp-bpf restricting syscalls to the minimum. And about crash? Parent auto-restarts it. #p2p #security #opensource

Building a DNS layer where every zone is a keypair, not a leased string from a registrar. Lookups are encrypted, records are signed, resolution is peer-to-peer. No one can take your name because no one gave it to you. #p2p #dns #decentralized #privacy #cryptography #networking

no company, no blockchain, no infrastructure dependency. just you =] the shot shows reading a post by its content hash, resolving its .tes URL, and DNS stats You can now open http://<base32_zone_pubkeys>.tes in a regular browser and see a rendered

The way #OpenBSD allows restrictions on system calls is very nice. pledge(2) man.openbsd.org/pledge #tesseras.net

The next version of Rust might be one of the most transformative to the Rust ecosystem due to support for up-casting of trait objects. This makes `Any` significantly more powerful and potent!

first attempt at an online demo: demo.plakar.io :-)
