Garmin Pay: yes, you can do NFC tap-to-pay in stores without big tech
Late last year, I went on a long journey to rid myself of as much of my remaining ties to the big technology giants as I could. This journey is still ongoing, with only a few thin ties remaining, but there’s one big one I can scratch off the list: mobile in-store payments with NFC tap-to-pay. I used Google Pay and a WearOS smartwatch for this, but neither of those work on de-Googled Android – I … ⌘ Read more

Finally I propose that we increase the Twt Hash length from 7 to 12 and use the first 12 characters of the base32 encoded blake2b hash. This will solve two problems, the fact that all hashes today either end in q or a (oops) 😅 And increasing the Twt Hash size will ensure that we never run into the chance of collision for ions to come. Chances of a 50% collision with 64 bits / 12 characters is roughly ~12.44B Twts. That ought to be enough! – I also propose that we modify all our clients and make this change from the 1st July 2025, which will be Yarn.social’s 5th birthday and 5 years since I started this whole project and endeavour! 😱 #Twtxt #Update

Just like we don’t write emails by hand anymore (See: #a3adoka), we don’t manually write Twts or update our twtxt.txt feeds. Instead, we use modern Twtxt clients that conform to the specifications at Twtxt.dev for a seamless, automated experience. #Twtxt #Twt #UserExperience

Nobody writes emails by hand using RFC 5322 anymore, nor do we manually send them through telnet and SMTP commands. The days of crafting emails in raw format and dialing into servers are long gone. Modern email clients and services handle it all seamlessly in the background, making email easier than ever to send and receive—without needing to understand the protocols or formats behind it! #Email #SMTP #RFC #Automation

Crucial Wii homebrew library contains code stolen from Nintendo, RTEMS
The Wii homebrew community has been dealt a pretty serious blow, as developers of The Homebrew Channel for the Wii have discovered that not only does an important library most Wii homebrew software rely on use code stolen straight from Nintendo, that same library also uses code taken from an open source real-time operating system without giving proper attribution.

@movq@www.uninformativ.de I started with Delphi in school, the book (that we never ever used even once and I also never looked at) taught Pascal. The UI part felt easy at first but prevented me from understanding fundamental stuff like procedures or functions or even begin and end blocks for ifs or loops. For example I always thought that I needed to have a button somewhere, even if hidden. That gave me a handler procedure where I could put code and somehow call it. Two or three years later, a new mate from the parallel class finally told me that this wasn’t necessary and how to do thing better.

You know all too well that back in the day there was not a whole lot of information out there. And the bits that did exist were well hidden. At least from me. Eventually discovering planet-quellcodes.de (I don’t remember if that was the original forum or if that got split off from some other board) via my best schoolmate was like finding the Amber Room. Yeah, reading the ITG book would have been a very good idea for sure. :-)

In hindsight, a console program without the UI overhead might have been better. At least for the very start. Much less things to worry about or get lost.

Hence, I’d recommend to start programming with a console program. As for the language, not sure. But Python is probably a good choice, it doesn’t require a lot of surrounding boilerplate like, say Java or Go. It also does exceptionally well in the principle of least surprise.

9front “CLAUSE 15 COMMON ELEMENTS OF MAUS AND STAR TYPE” released
Few things in life make me happier than a new 9front release.

Can you automate the drawing with a script? On X11, you can:

#!/bin/sh

# Position the pointer at the center of the dot, then run this script.

sleep 1

start=$(xdotool getmouselocation --shell)
eval $start

r=400
steps=100
down=0

for step in $(seq $((steps + 1)) )
do
    # pi = 4 * atan(1)
    new_x=$(printf '%s + %s * c(%s / %s * 2 * (4 * a(1)))\n' $X $r $step $steps | bc -l)
    new_y=$(printf '%s + %s * s(%s / %s * 2 * (4 * a(1)))\n' $Y $r $step $steps | bc -l)

    xte "mousemove ${new_x%%.*} ${new_y%%.*}"
    if ! (( down ))
    then
        xte 'mousedown 1'
        down=1
    fi
done

xte 'mouseup 1'
xte "mousemove $X $Y"

Interestingly, you can abuse the scoring system (not manually, only with a script). Since the mouse jumps to the locations along the circle, you can just use very few steps and still get a great score because every step you make is very accurate – but the result looks funny:

@prologic@twtxt.net Do you use anything for analytics?

Interesting factoid… By inspecting my “followers” list every now and again, I can tell who uses a client like jenny, tt or any other client where fetches are driven by user interactions of invoking the app. What do we call this type of client? Hmmm 🤔 Then I can tell who uses yarnd because they are “seen” more frequently 🤣

About the nuclear power plant on the Moon, they are beating us. There was a time we were ahead, but I understand nothing lasts forever. Now, being a world power for only one hundred and twenty some years, and a super power for around seventy sure is a record (as in short-lived). The Roman Empire lasted over 500 years!

It was fairly gray all day. Just before I went on a stroll, a rain shower paid us a visit. Then, the sun took over. Great timing. It’s crazy how rapidly the greenery grows. No comparison to only two weeks ago.

The wonderful world of Linux package managers
One of the strong points of Linux has always been how solid the experience of installing and managing software is. Contrarily to what happens in the Windows and macOS world, software on Linux is obtained through something called a package manager, a piece of software that manages any piece of software the user installs, as well as its dependencies, automatically. ↫ Luca Bramè at Libre.News It truly is.

@eapl.me@eapl.me I wouldn’t call it natural, it is the way Bluesky decided to handle handles (not meaning to make a pun, or anything). There is no other way, but that.

The bottomline is, there are agreed upon “standards”, right? From example, on Yarnd you show as “eapl.me”, from “eapl.me”. A kind of weird redundancy because on twtxt, ever since I started using it, one will expect to see a “nick” (equivalent to a person’s first name), from “a domain” (like a surname).

There is nothing holding back someone from giving themselves the nick:

thisismyawesomenickforwhichiwillbeknownforeverandeveritsgreatisntit

But, do we really want that? 😅

hehe, just catching up on this thread! I’ve replied in another that using periods/dots sounds good to me as it’s usual in domains, but perhaps some agreement would be needed. For now I think any character is valid as long as it is not a space.
For example we are using this for PHP twtxt.php#L153

@aelaraji@aelaraji.com I use to be a pot or more a day but have cut that back in the last 4 or so years to just 2-3 cups. Main reason was because I was getting jittery which didn’t happen before.
