Soldering steps and common problems – Adafruit
These are nice references when you start to learn soldering:
The right part of the image from Adafruit is an almost 10 year old one that is heavily copied without reference. With reference, it is at¹

TL;DR: There is no simple character that works on both MacOS and Windows.
[Wayback/Archive] sorting – Simple to enter Unicode character that would sort after Z in most cases? – Stack Overflow (thanks [Wayback/Archive] sorin and [Wayback/Archive] degenerate):
A
On Windows, none of these options work because they all sort before A.
A solution I ended up using is an Arabic character:
ٴ This folder comes after z in windows
Source
According to [Wayback/Archive] What Unicode character is this ?, the above mentioned character is U+0674 : ARABIC LETTER HIGH HAMZA.
Note that on Windows the ٴ character displays at the start of the filename, but on MacOS in Finder it ends up behind the extension (as Arabic script is right-to-left) and is very hard to remove. On the MacOS Terminal it ends up on the left and is easy to modify.

Cool interesting video: [Wayback/Archive] UTF-8, Explained Simply – YouTube
It covers both history from the late 1800s Baudot Code (also known as ITA1) via 1930s ITA2 and 1950’s EBCDIC / FIELDATA ages through 7-bit ASCII in the 1970s and incompatible UCS-2 (now UTF-16) of the 1990s to the current day and age of UTF-8 (which actually started out on a placemat in 1992).
Though mentioning 8-bit encoding, it skips details of extended ASCII encodings like ISO/IEC 8859 and Windows-1252.
It goes to quite some length on decoding UTF-8 and showing how forgiving the UTF-8 standard is. Yes, it is a self-synchronising code thanks to the venerable Ken Thompson.
Definitely worth watching as it also covers the Zero-width joiner which is not just important for combining Emoji, as it is used by many people nowadays, but got in fact implemented to support various scripts like Arabic script or any Indic script.
Oh, the placemat story: Read the rest of this entry »

Dit is net zo nalatig als de Odildo hack waar alle klantgegevens mee op straat kwamen te liggen: [Wayback/Archive] Odido-router verzamelt analytics van je huishouden
Bevindingen in het kort
- De Odido-router haalt bij een nieuwe WAN-verbinding een bash-script op over een onversleutelde HTTP-verbinding.
- Je kan dit script manipuleren om een root shell op je router te krijgen.
- Als je TLS-verkeer mitm’t zie je analytics-data over de lijn gaan; de scripters hebben TLS-validatie uitgezet (`curl -k`) dus je kan dit ‘versleutelde’ analytics-verkeer inzien.
- Je router stuurt namen en MAC-adressen van devices in je huis door naar Lifemote. Verder deelt het ding de SSID’s en MAC-adressen van WiFi-netwerken in de buurt. En wat analytics-stats over je dataverbruik. Lifemote adverteert met “AI-Powered Home Wi-Fi Solutions for ISPs”. Het voelt wat vies dat zij AI’s gaan trainen met data uit mijn huishouden. Daar vind ik wat van.

Finding a reference to DASM while researching yesterday’s post @jpluimers on Twitter: “@b0rk @jilles_com Acids vs bases.”, it felt even more like a trip like memory lane as I had used it in the 1980s on Apple ][ and Apple //e after mainly using EDASM. Lisa and Merlin.
I am glad that it is still alive and kicking with home page at [Wayback/Archive] dasm – macro assembler for 8-bit machines and repository at [Wayback/Archive] dasm-assembler/dasm: Macro assembler with support for several 8-bit microprocessors.
Especially this history section on the home page rang a bell:
- Matthew Dillon started dasm in 1987-1988.
- Olaf “Rhialto” Seibert extended dasm in 1995.
- Andrew “Dr.Boo” Davie maintained dasm in 2003-2008.
- Peter Fröhlich maintained dasm in 2008-2015.
- In 2019, the dasm source code and releases were moved to GitHub.
More links from this trip down memory lane:

For Some links on getting the most recent defragmentation time of a Windows volume I needed to copy back and forth some XML code back and forth between my ARM MacBook Pro to a remote Windows machine accessing via the Microsoft Windows App (the app formerly known as Microsoft Remote Desktop for Mac).
The problem with that is the copying would lose line breaks, which for XML meaning is no problem, but for human understandability while editing the XML in the Event View query dialog was.
So I decided to go to the “Code” view in my Classic WordPress editor (did I ever tell you much I dislike – especially the accessibility of – the not so new but still haughty named Gutenberg editor?), copied the HTML encoded form and wanted to convert it to unencoded XML text.
Well, here I got to naming confusion land, on which I will talk further below, but first two of the potential solutions:

A few years back I tweeted [Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on Twitter: “@b0rk @jilles_com Acids vs bases.”
It was a kind of tongue-in-cheek reaction (with a way better picture below) to a very valuable post by b0rk (Julia Evans) on both Twitter and Mastodon [Wayback/Archive] Julia Evans on Twitter: “bases” / [Wayback/Archive] Julia Evans: “bases title: bases # we usually…” – Mastodon for two reasons:
- There are various interpretations of bases
- Octal is very important to educate as errors introduced by its support are hard to spot even if you do know about octal.

The description of [Wayback/Archive] GitHub – dessant/web-archives: Browser extension for viewing archived and cached versions of web pages, available for Chrome, Edge and Safari is missing Firefox and Opera, but in the meantime the extension is available in these stores for:
As a great example of how to write a browser plugin for all these architectures, it shows how to write this in mostly JavaScript with Vue.js with a tiny bit of play HTML.
Web Archives is a plugin that lets you search either the URL from the current browser tab, or a URL you type, within various archival sites (all Wikipedia links):
