Putting Some Zig in a Linux-Based 3D Printer

PSA: In #debian unstable, "copy_exec /bin/lsblk" stopped working when used in an initramfs-tools hook. Why? The #busybox 1.38.0 upload enabled the lsblk applet and (to my surprise) the "copy_exec" function will not overwrite the destination file if it already exists. Since busybox lsblk does not support any command line flags, my initramfs scripts which expected lsblk from util-linux failed in funny and non-obvious ways. Time to make these scripts more robust. :)

Just finished a PoC if i could bootstrap pkgsrc on my self-assembled minimal docker container.

Ingredients: skarnet-musl-toolchain. busybox-static, toybox-static, gawk, gsed, gtar, gmake, libz, libexpat, libxcrypt, libbsd, libmd, musl-{bsdcompat,fts,obstack,rpmatch}, and finally pkgsrc from netbsd.

after a few ins and outs, and learning the ropes, bootstrapping worked flawlessly.

shout out for the developers for their good work!

Ten years ago, I built a #WebSocket server using nothing but #UNIX shell and #BusyBox tools. 🛠️

Looking back at `websocket.sh` today, it's just a fun, interesting project that shows how far you can stretch basic tools.

Following on from my #kindle hacking - I haven't yet got a custom kernel booting but I did use the bootargs to drop into a simple #busybox shell which meant I could root the device by changing the password:

1. Connected up serial lines (1.8v)
2. Drop into u-boot
3. `setenv bootargs setenv bootargs root=/dev/mmcblk0p1 earlyprintk console=ttymxc0,115200 init=/bin/sh`
4. `boot`
5. Once it drops into the busybox shell do `mount -o remount, rw /` to remount the as rw
6. `passwd`
7. Set a new password
8. `reboot now` and this time let it fully boot up
9. Login in via serial using `root` and your password

In the spirit of there always being 1 more #vi clone than one thinks, notice that @lpar 's list is lacking Ali Gholami Rudi's #neatvi which is packaged in #pkgsrc and about a decade old now.

https://pkgsrc.se/editors/neatvi

And even then the rule still applies. There's 1 more clone: Sterling Huxley's and Brent Roman's #viless, a quarter of a century old and what #BusyBox supplies.

Randomly wondering: Does anyone know what's going on with #Busybox? The last release is a year and half old, there has been development in Git, including bugfixes (including ones that may be relevant for security, like 3fb6b31c716669e12f75a2accd31bb7685b1a1cb), but there's no sign of a new release. The mailing list is mostly people complaining gitweb doesn't work, and a fix for httpd I sent early this month didn't get any response… ​:neocat_think:​

After discovering #TiddlyWiki from @jbaty, I went ahead to give #FeatherWiki (lightweight TW fork) a spin as a personal #braindump bin. I really like how it’s just a HTML file at 58kb!

Using #Android, it failed due to Android Storage Access Framework (#SAF) limitations. I ended using the amazing #Termux once again to run #Busybox #httpd, automate the whole process of opening, serving & saving back to my…

Varastossa makaa pari hyvin vanhaa QNAP’n NAS palvelinta ja siellä olisi terakaupalla hyvää tilaa esim. perheen kuville, puhelinten varmuuskopioiden ja kuvagallerialle. En vaan ole varma saako niistä enää mitään käyttöön, kun QNAPin tuki NASin Busybox distrolle taitaa olla loppunut vuosia sitten.

My first suspect for a #login not supporting -- would be something with a 1980s history pre-dating standard #getopt, such as Solaris, which is ironic given that #inetutils has its only -- present in conditionally compiled code targetting Solaris.

#FreeBSD, #NetBSD, and #OpenBSD login all use getopt(), pervasive in these worlds for decades, as do the util-linux login (used by Debian et al.), and the #Illumos and #BusyBox logins.

#suckless login supports -- via ARGBEGIN.

anyone know of a repo with a shairport-sync pkg that defaults to airplay 1?
