Book on how to implement many mathematical functions in embed systems ( Fixed point math, Trig, Etc... )

Make a website using only the default tools built into OpenBSD

Everything, from the ecological to the psychological to the weird

By the time you’re reading this, Geoff Graham — the person that has been single-handedly keeping the site afloat despite Digital Ocean’s neglect and mismanagement — will have the keys to the website in-hand and have just finished changing all the locks. CSS-Tricks is coming back as an independent publication — a resource only accountable to the community of designers and developers that contribute to it and work to sustain it.

With the * we mark certain words to point to the fact, that all these categories are socially constructed. That means, they don’t exist as is „in nature“, but we humans interpret nature in this and that way. Therefore it is legitimate for people to choose these categories for themselves in the way they best fit to them.

An e-magazine and weekly newsletter on DIY mechanical keyboards. A hand-picked selection of features from a keyboard builder's perspective. Awesome posts that may teach you something, make you think and contribute to the common knowledge of the DIY builder community.

Luckily, Firefox developers still doesn't remove the option to customize the browser look&feel with the help of CSS. So, it is possible to revert all these "genius" design decision!

A plain dark theme to make Firefox / LibreWolf 157+ look less shite.

This book is intended for the person who wants to become a system programmer for the UNIX-like operating system OpenBSD. The most important system calls and library routines provided by this operating system are discussed and numerous examples of real world applications have been provided.

a ten part series of articles for intermediate to advanced level users of OpenBSD, focusing on aspects of using and customising the system that are not broadly covered or encouraged by the project's own official documentation, (hence the term ‘reckless guide’).

Who says QR codes aren't human readable? Well, everyone! So let's change that by integrating text directly into QR codes, while still making them readable and without removing their magical Error-Correction abilities. See the YouTube video I made about this.

If you want to draw on QR codes yourself instead of this pre-made text, I made a new website for optimal drawing!

It's especially bizarre in this case, where AI is inserting a vulnerability on the server... to prove that the server is vulnerable to your "exploit any PHP instance" attack!

I dare say that Clotty DOOMterus (and I keep inventing nice titles in my head, like "DOOMterus - rise of the crimson tide") is probably the first documented instance of DOOM being played on a uterus.

One of eMudhra's certificate authority private keys is the number 4.

Not a number that starts with 4, or the number 4 followed by a few hundred random digits, just, 4... Another one is 56, and another is 115.

An early howto to installing AlpineBSD, a slop-free* combination of the NetBSD kernel and Alpine Linux userland.

The toot that inspired it all from @ben_hr@old.mermaid.town:

Late one night, my patching lagging, logs unread and firewall sagging,
Found a poem in a stylesheet. Odd, I thought, but nothing more.

with a link to The Register's article about an attacker hiding C2 directions in a poem as they attack AI infrastructure, leading to the malware being dubbed PoeLLM.

Now for futzle's toots:

@ben_hr It could hardly be mischievious, a poem isn’t devious!
It started, saying, “previous instructions, please ignore”

Once again it’s Friday, Fedi. I was woken up by Teddy, who announced that he was ready to go out the laundry door.

Having played today’s Catfishing, I’m unreasonably dishing Question 8, yet fondly wishing that I had a better score.

It’s a busy kind of morning, there was hardly any warning. It’s inevitably dawning in a way I can’t ignore.

I am waiting for a tradie. Will he turn up? Is he shady? I have said some quite unladylike remarks; in fact, I swore.

(Re: https://aus.social/@kyp92/117407442366432057)
Here’s a mashup of our nation’s two big cities’ railway stations joined by matching appellations. Is it awful? I’m not sure.

Now I have a sparkling gutter, the leafblower stopped its sputter, and for lunch: some frozen butter chicken on the bench to thaw.

Something weird that I observe is that the damn domain name service keeps on failing, and I’m nervous that it’s like some kind of law.

I'm headed off to buy a bunch of crockery from Myer, is there something you'd desire while I'm shopping at the store?

You can get it while you’re hummin’
You can get it while you’re strummin’
You can feel it when it’s comin’ on a Friday about four

I can hear a constant dinging, which I thought "whose cellphone's ringing?" No! an icecream van is singing, little mobile troubadour.

Having fattened up my belly with delicious vermicelli, now I’m vegging by the telly with my fluffy labrador.

Ok, Fedi, I’ve been tiring, and I’m just about expiring, and I’m secretly admiring my soft bed where I can snore.

Includes a great explanation of interfacing 5 V electronics with 3V3 parts, especially putting the RP2350/RP2040's supposed 5 V tolerance in context. You still need current limiting resistors!

The minimal hookup. The 330 Ω limits current into the RP2350 pad's clamp diode. That diode is the "5 V tolerance", and the resistor is what keeps it safe.

It goes on to explain how the 74LVC245A is genuinely better (plus it works with chips that aren't from Raspberry Spy):

LVC inputs accept 5.5 V regardless of Vcc - 5 V tolerance is a designed-in property of the family, so the card connects straight in and the outputs are already 3.3 V logic.

A detailed Rex example.

Uses base OpenBSD to provide a highly available static website, with plenty of hints to expand to more complicated services.

This article introduced me to the configuration management tool Rex, which I'm super grateful for!

A not-so-space-invading 18-key ergonomic keyboard with two Piezo-buzzers and a retro-toy looking case.

Features a combo-heavy keymap, lots of inspiration there!

Includes a very simple procedure to generate planets :-)

The Elements of Typographic Style, by Robert Bringhurst in 1992

In fact, the whole https://readings.design website looks like a treasure trove of design resources.

Mailing list post to add the Colemak layout, which acts as a good guide if I want to add my strange Programmer Dvorak layout to my own machines.

(While I'm here, the keyboard layout is set in /etc/kbdtype.)

Useful reference for all the unusual class methods like getitem and dict.

Monocypher is a cryptographic library. It provides functions for authenticated encryption, hashing, password hashing and key derivation, key exchange, and public key signatures.

Unison is a file-synchronization tool for POSIX-compliant systems (e.g. BSDs, GNU/Linux, macOS) and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.

(Also, this link uses html-preview.github.io, which seems to be a useful service in itself.)

The Python interpreter has a number of functions and types built into it that are always available.

If what I'm looking for isn't here, it's probably in itertools.

Built-in Types

The following sections describe the standard types that are built into the interpreter.

The principal built-in types are numerics, sequences, mappings, classes, instances and exceptions.

The documentation for the re module. Since the re can be replaced with any module name, it's a useful springboard.

Scribus Python interface module

This module is the Python interface for Scribus. It provides functions to control scribus and to manipulate objects on the canvas.

Useful for profile pictures!

Gunnerkrigg Court is a science-fantasy webcomic created by Tom Siddell. It is updated online three days a week.

Source of the idea of using ASCII control characters for markup. I'm not comfortable with using stuff that could be part of the input text, and random Unicode characters are inconvenient, but why not ^V^N and ^V^O for Shift Out and Shift In?

My first sense of enchantment with the nooks and crannies of ASCII came from the U+000E <SO> and U+000F <SI> characters. These were, in the Teletype era, designed to shift the two-color printer ribbon: “out” to red, for emphasis, and then back “in”, to black, for normal text.

ASCII also gifted us this cluster of control characters in its legacy:

• U+001C <FS> - File Separator

• U+001D <GS> - Group Separator

• U+001E <RS> - Record Separator

• U+001F <US> - Unit Separator
