second, there’s predictions. a prediction is Done when it’s made. you could add comments, explanations, models &c, but the prediction can be Done and stand there on its own. (there is a slight problem with the fact that predictions need to be updated over time, though, so there is some Piling there as well).

Yesterday I ordered a blanket for an incredible amount of money, more precisely a weighted blanket. Now I hope that it will be delivered quickly and that it really has the positive effects that are being advertised. Although I can usually fall asleep quickly in the evening with a sleeping mask and earplugs, I never manage to sleep through the night, I am never woken up by the alarm clock because I wake up earlier. In the morning I feel tired almost every day, sometimes even the whole day, which then also limits my c … ⌘ Read more

** Forth, a tool for cultivating community **
I watch most of the recordings of the Forth2020’s Zoom chats. A topic that comes up from time to time is how to get more folks interested in Forth — especially younger folks. In my weird little corner of the internet I can say that there are certainly young folks interested in Forth!

I wonder if the issue at play is less one of interest, and more one of cross c … ⌘ Read more

Isode: Successfully Managing HF Radio Networks
With the potential for new technologies to cause interference to traditional communications networks and even space itself at the risk of becoming weaponised, it is important to make sure that you always have a backup plan for your communications ready and waiting.

Should the worst happen and your primary network, typically SatCom, go down you need to ensure that you can still communicate with your forces wherever they are, and that c … ⌘ Read more

Lossless Image Compression in O(n) Time
Introducing QOI — the Quite OK Image Format. It losslessly compresses RGB and
RGBA images to a similar size of PNG, while offering a 20x-50x speedup in
compression and 3x-4x speedup in decompression. All single-threaded, no
SIMD. It’s also stupidly simple.

tl;dr: 300 lines of C, single header,
source on github,
benchmark results here.

Important notes for LARBS users
Two notes for LARBS users:

  1. Xorg went through some updates last week that changed how it calculates dots-per-inch (DPI) on screens. There’s a chance that you might update and find your font extra large or small. If so, you can just manually addxrandr --dpi 96 to the beginning of your xprofile to set the DPI to the typical 96 (or whatever number looks best).

** Operators in C **
Following up my notes on Data Types and Variables in C here are notes on operators in C.

An operator is a symbol that represents a mathematical or logical operation. An operator effects operands.

C provides a number of operators.

Some arithmetic operators include,

”`hljs plaintext

+

*
/
%
”`

% is the most exciting of the list, it is called modulo and it returns the remainder after division. Of note, modulo c … ⌘ Read more

@adi@f.adi.onl What about this one?

SRCFILES = $(wildcard *)
# remove existing *.gz (actually doubles entries)
CLEANSRC = $(SRCFILES:.gz=)
DSTFILES = $(addsuffix .gz, $(CLEANSRC))

%.gz: %
	gzip -c  $< > $<.gz

all: $(DSTFILES)

You must not have subdirectories in that folder, though.

↳ In-reply-to » @movq Another feature request: sometimes I start writing a twt but then would like to discard it. It would be great if jeny could detect that I did not wrote (or saved) anything and then discards the twt instead of creating an "empty" one.

@movq@www.uninformativ.de I don’t by your example (rebasing behaviour), sorry.

Writing a twt is more similiar to writing a commit message. Git does quite some checks to detect that nothing new was written and happily discards a commit if you just leave the editor. You don’t need any special action, just quit your editor. Git will take care for the rest.

But it’s OK as it is. I just didn’t expect that I have to select and delete all to discard a twt. So it’s C-x h C-w C-x C-c for me.

@movq@www.uninformativ.de My workflow is as follows.

I hit “reply” hotkey and my editor comes up.

With or without writing something I close my editor without saving the content.

Of course I close it by C-x C-c, not by :q! ;-)

Jenny finds the temp file unchanged, e.g. it’s content is the same as it was when my editor was started. I would like that jenny discards the reply then.

Autosaving is no problem either. Real editors do this to a temporary (kind of backup) file. Only in case of a crash that file is consulted and the user is asked if she would like to continue with that stored content.

** Data Types and Variables in C **
I’ve been writing a heap of Lua lately — this has lead to my becoming interested, again, in C. Here are some ancient notes I dug up on the most basics of data types and variables in C.

All of a computer’s memory is comprised of bits. A sequence of 8 bits forms a byte. A group of bytes (typically 4 or 8) form a word. Each word is associated with a memory address. The address increases by 1 with each byte of memory.

In C, a byte is an object that is as big as t … ⌘ Read more

Obscenities are symptoms of weak minds.
Over the past few years, I made the decision to totally cut obscenities out from my speech. You might actually be able to find recordings of me cursing four or five years ago, but as of now, I really stand by my decision.

Obscenities are the linguistic equivalent of an trashy emaciated person entirely decked in tattoos, smoking cigarettes and wearing a shirt with nudity on it. They’ll defend what they do on the idea that it’s someone “their right,” or “e … ⌘ Read more
