Now/log
Just putting random stuff I’m working on and/or thinking about.
I’ll try to update this daily. RSS should reflect this.
0420
Updated and rebuilt youtubedr for Plan 9. Faster downloads but also
incompatible command line arguments. Youtube on 9 docs
updated.
0419
Added more op stubs to pdffs. This doesn’t do anything but helps to have a list of all ops in one place, rather than scattered across PDF spec.
0418
Nice weather. No computers.
0417
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.
0416
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.
0415
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.
0414
uxn now includes a mkfile to build it on 9front!
Audio programs run well and produce sounds :)
0413
zuke 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
0412
Reading PDF spec. Checking embedded font formats out. Should be pretty doable to do rendering. Hopefully pdffs 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.
0411
No computers.
0410
Some more work on pdffs.
0409
pdffs 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.
0408
Added m4a playback support to zuke.
Fixed sources syncing to /n/ftrv.se.
0407
Computer music of 1970s: Analysis of Jean-Claude Risset’s Songes (unfortunately, only in French).
Small bytebeat(?) in 10 minutes:

0406
Fixed a small bug in mp3dec and
aacdec: the proc wasn’t waiting for
pcmconv to finish, sometimes causing trouble.
0405
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:
.
0403-0404
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.
0402
Extensible efficient non-linear pattern matching with backtracking for non-free data types
0401
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.
