Recently turned 80L of sugar wine (containing 12kg of sugar) into ~10
bottles of vodka. It was an easy and smooth process. Something that's
really aided my hooching lately is adding a small amount of diammonium
phosphate and magnesium sulfate to the start of fermentation -- barely
a pitch, hardly a gram of each -- but it somehow makes a huge difference
in fermentation time.

I plan on turning most of it into gin, but with the vodka, I've made
some knock-off Bailey's that turned out amazing well (and only cost $1
to make a bottle of!) and tomorrow I'll try making a blood mary. Tomato
juice is not sold here so I intend to make some fake V8 from a mix of
tomato, carrot, salad greens, onion, bell pepper and then I'll add a
dash of worcestor sauce and hot sauce to the cocktail, along with some
lemon juice.

When I more-or-less perfect my Bailey's and Bloody Mary recipes I will
share them here.

tripex 1.2

2025-01-07T05:24:05+00:00

tripex 1.2 release notes
+ -f flag to read a list of expressions from a file
* -s flag now takes an argument for when to begin/end stacking. negative values mean to stop stacking after the absolute value of the index.

apply the patch as follows (make sure to apply the previous patch first:)
patch tripex.c tripex-1.2.patch

then recompile the software as follows:
gcc tripex.c -o tripex -O3 -lcrypt

here's an example of the new features combined for efficient dictionary searches.
because expressions from argv are parsed after files, we have to put our first expression in it's own file :(.
'-s -1' means to stop stacking after the first expression, so it will first check if it is even possible to match with any of the dictionary expressions.

aspell -d en dump master | grep "^[a-z]\{5,5\}$" > len5dict.txt
echo "[a-z]\{5,5\}" > 5a-z.txt
./tripex -n $(nproc) -s -1 -f 5a-z.txt -f len5dict.txt

tripex 1.1

2025-01-05T06:05:26+00:00

version 1.1, cryptography patch.
i forgot to audit the cryptography; i made a huge boneheaded mistake
with the key filter (thing that turns pure random bytes into printable
ascii) where it was skewing a lot. now it uses an 85 character subset
(256 % 85 = 1) which has a very tiny amount of skew but doesn't lose
as much entropy as an unskewed 64 character subset of ascii would.
the default key length is also increased to 10, so that it would be
~64 shannons of entropy total (a tripcode has 60 shannons.)

here is the patch file, apply it to the original as follows:
patch tripex.c tripex-1.1.patch

then recompile the program as follows:
gcc tripex.c -o tripex -O3 -lcrypt

tripex tripcode finding software

2025-01-05T00:04:23+00:00

releasing version 1.0 of my tripcode finding program, 'tripex'

compile the program as follows:
gcc tripex.c -o tripex -O3 -lcrypt

example #1; find tripcodes containing 'nice' (case insensitive):
./tripex -n $(nproc) -i nice

example #2; find tripcodes starting with either 'giko' or 'mona':
./tripex -n $(nproc) ^giko ^mona

example #3; find fully lowercase tripcodes with quads:
./tripex -s -n $(nproc) "^[a-z]*$" "$.$\1\{3,\}"

untested on anything but GNU/Linux with glibc, but it would probably work on FreeBSD too.
don't trust any update posts unless they have my tripcode or you can audit them yourself!

As a limited experiment, all streams are open by default when you
join. How do you feel about this? Is it good or bad? Should there be
a button somewhere to open/close all streams?

I prefer if you share your opinions with your name so I can go with

can't beleaf it's been almost 8 months (?)
since i last posted on one of these BBSes... i
guess im posting here specifically because of
its memorable-ness???? time flies man!!!!! i
recently got into baking, i made a really good
strawberry cake yesterday. im also an
alcoholic now #lifesgood

boards is still alive-iiiishhh, and it's about
to turn a year old!! ive moved on to newer
things, though. pikidiary is my new
microblogging site, heavily inspired by its
boardsian roots. much more normie-y, but still
fun.

anyways, i miss a lot of y'all!! email me if
you know who i am (⁠*´⁠︶`⁠) cya around!!!!

Recently produced ~12 liters of "low wines" from sugar washes.

Biggest game changer in my fermentation for distillation lately:
I add a tablespoon or two of diammonium phosphate and tiny pinch of
magnesium sulfate per ~20L of ferment I do. Seems to make a pretty
big difference: ferments go faster and cleaner.

Picked up about 200g of baking soda (sodium bicarbonate) today and
converted it to washing soda (sodium carbonate) by throwing it in a
saucepan on the stove at a low heat and constantly stirring. Sure
enough, I could see the powder "boiling" -- despite wearing a face
mask, some funky smells came through. After about 20 minutes or so,
the texture of the powder appeared to change, and the powder seemed to
stop reacting.

Spilled a little in the process. Post-cook weight of sodium carbonate
was about 120g which is consistent with the theory.

Tomorrow I'll be throwing my 12 liters of "low wines" into the pot still
with 3-4 liters water and 4 tablespoons of washing soda. This should
result in a large volume of hearts, which will be turned into... gin!
this Saturday.

Stay tuned for updates.

El Topo is a good one - a psychedelic Western released in 1970.

It's about a gunslinger in a nameless desert searching for enlightenment. The
movie deals heavily in Western and Eastern spiritual symbolism and philosophy.
A lot of bizarre occurences and characters - the movie at parts is very surreal
and almost comedic and in others is dramatic or very violent.

It's been watched by and has inspired a lot of creatives and in my opinion
should be watched at least once by anybody who says they enjoy cinema.
