Newest entries[1].
Previous month[2].
Fixes for libtags[3]: all module formats metadata is treated as CP437 now. Empty textual tags are now ignored.
Cosmetic fixes and c9[4] submodule update for 9pro[5].
Made image resampler slightly faster in Netsurf for Plan 9[6].
9
Today's listen[7] that I got a few years back on an audio cassette. Check out Extreme Ultimate in general, lots of great stuff there. I particularly love Necro Deathmort.

kvik[8] provided issue reports and fixes for c9[9] which are now merged.
`sshnet` to a Windows machine worked. That machine provides network to Raspi 4 with 9front over ethernet. I need to set this Raspi so that I can rcpu there.
I also need to test rndis with Raspi.
Repackaged treason[10] with latest small fixes.
No computers?
Optimized `resample` in imgtools[11] to make it faster. It's still too slow to use for video scaling in treason[12].
Today's listen.[13]
Fixed a small bug in `zuke` that caused a wrong duration and volume to show on 32-bit platforms.
Added support for NAL lengths other than `4` to mcfs[14]. That should make some old MP4/H.264 videos playable.
Fixed sleep/delay functionality in npe[15]. Apparently I typed one extra zero and the timings were off in some cases.
A random quote about Scottish that I found very funny:
When they were small I asked my Aussie kids to say goodnight in Scottish to their visiting Grandmother. Guid nicht. Instead of wishing her a good night they pronounced it “Get nicked”. Which required a lot of explaining.
I got a klaxon for my bike. It does make a funny noise!
Today's listen.[16]
Updated and rebuilt `youtubedr` for Plan 9. Faster downloads but also incompatible command line arguments. Youtube on 9 docs updated[17].
updated
Added more op stubs to pdffs[18]. This doesn't do anything but helps to have a list of all ops in one place, rather than scattered across PDF spec.
Today's listen.[19]
Nice weather. No computers.
No computers today. I spent this week writing Java at work and that makes me not want to do any coding. I need to change my job.
On something better, long dresses (specifically maxi slim) are totally my thing now. Also I tried out my old earrings (my earlobes are stretched now) and it looks fine! And doesn't hurt at all, something I was not sure about, stretching considered.
I got an e-reader (Boox Nova 3) which I immediately rooted. Today I also installed openssh, so I can copy documents from 9front to the reader and even open them remotely. I could do 9p as well but sshfs is enough. I want to try attaching the ereader to the side of my laptops display and configure plumber to open PDFs there. That'd be lit.
Yesterday I went to a local "russian" shop and bought lots of sweets along with сметана. Today I made traditional belarusian potato pancakes which we all ate way too fast to take a good picture, so here's the last one left on a plate[20].

uxn[21] now includes a `mkfile` to build it on 9front! Audio programs run well and produce sounds :)
zuke[22] is now shipped with 9front. All of the `juke` is removed, but you probably didn't even know it was there to begin with :P
Reading PDF spec. Checking embedded font formats out. Should be pretty doable to do rendering. Hopefully pdffs[23] will be accepted for GSOC via Plan 9 project so it gets much further during summer. PDF reader with MIT license for everyone!
Hope my e-reader comes soon, can't wait to stop reading from a laptop screen X__x.
No computers.
Some more work on pdffs[24].
Today's listen[25].
pdffs[26] is now successfully extracting CCITTFax images as TIFF. Those can be viewed with `page`. That's a new addition to already working DCT, JBIG2 and JPEG2000 extraction.
Added m4a playback support to zuke[27].
Fixed sources syncing to `/n/ftrv.se`.

Fixed a small bug in mp3dec[29] and aacdec[30]: the proc wasn't waiting for `pcmconv` to finish, sometimes causing trouble.
Went to a forest. It was really cold but quiet and calming. Took a few pictures on my crappy phone of which I liked one:
No computers.
Decided to start cooking (and baking) traditional Belarusian/Russian things. Want to find out what my friends from Syria think about those when they taste it.
Extensible efficient non-linear pattern matching with backtracking for non-free data types[31]
[31] Extensible efficient non-linear pattern matching with backtracking for non-free data types
Worked more on the parser of my programming language. Got declarations, constants and arrays work. It's slowly shaping. I'm thinking of doing interpretation only, since I want to write the compiler in that same very language as soon as possible, so I don't waste time on C version.
