so!! i am excited!!! to have finally finished the complete reimplementation of the memory-25x applet for managing SPI NOR flashes. it is called memory-25q and it took an enormous amount of effort, because i have decided to Build It Properly

want to jump to the docs (there are a lot of docs, including on the fundamentals of (Q)SPI flashes) or read the code? here we go:

now, why did i do that? two reasons. memory-25x is one of the first applets i made, ~7 years ago, and i had no idea what kind of UI i should be building (yet). to make it worse, i thought that SPI NOR flashes were "easy", you could "just send a few bytes and that's basically it".

nothing could be further from truth. first off, SPI NOR flashes don't really existโ€”there is no spec, no standard organization that can say "no, your thing is not compliant", no order to any of this. every vendor does whatever they want, and then every other year JEDEC writes down all of the unhinged shit they did. here is the list of six incompatible methods to turn a single bit on or off, as a warmup

second, SPI flashes have an absolutely absurd diversity of framings. you cannot even express it without building a meta-framework for abstracting over all the ways people have come up to squeeze 8 bits into 2 or 4 wires. then on top of it you have to manage a bunch of global state that affects framing in subtle or sometimes really fundamental ways, without having any way to find out that you've made an error besides "you compare the actual data with the expected data (or its checksum) and it is not equal"

anyway, the new applet should be excellent at any daily task and at least okay at >90% of the exotic ones. also it's easily generalized for the (completely incompatible on the wire) QSPI NAND 25N series, octal or DTR variants, etc

Good morning,
Good morning,
Good morning,

It's sunny (though some rain is expected). I've had my espresso, and my mood is currently positive. All the bad thoughts I had yesterday evening are now something like "well, I can deal with it". And that's good.

I've almost finished my next IT Notes blog post. I'll try to review and polish it so I can finally make it public.

Meanwhile, have a great day!

RE: mastodon.de/@ErikUden/11439000

Everyone here can see the Cuba I've experienced less than one year ago. Friends in Luxemburg, who participated in a brigade in late 2025 a few months after mine, already told me a different story. What I hear from the people of Cuba is terrible: a complete power outage, no more garbage trucks able to pick up trash due to gas shortages, food and health crisis.

Let it be known that the collapse of the Cuban system was always brought about by the American hegemon. Cuba shall never be remembered as something that thrived in a capitalist world, but despite of it. Despite the sanctions, despite the unprecedented international blockade by the largest economy and military on earth, a small island protected its success in education, healthcare, and quality of life, as something that was once merely seen as the colonizer's plantation.

Some day a man will approach you and tell you that socialism can never work and cite Cuba as an example. It is your job to beat that man to death with your bare hands.

RE: digitalcourage.social/@echo_pb

A major victory -- although the fight still isn't over. From the article:

"In a sensational turn of events in the fight against Chat Control, a majority in the European Parliament voted today to end the untargeted mass scanning of private communications. In doing so, the Parliament firmly rejected the error-prone and unconstitutional surveillance practices of recent years. Pressure is now mounting on EU governments to respect the MEPsโ€™ vote and bury untargeted mass surveillance in Europe once and for all....

Based on todayโ€™s mandate, trilogue negotiations between the EU Parliament, the European Commission, and the Council of the EU are set to begin as early as tomorrow. Negotiations are taking place under extreme time pressure, as the current interim regulation authorizing Chat Control expires on April 6. The EU Commission and the vast majority of the EU Councilโ€”except for Italyโ€”have so far categorically rejected any restrictions on untargeted mass scanning."

It's also worth highlighting that this is also a victory for the EU against US tech imperialism:

"The push for Chat Control is heavily driven by foreign-funded lobby groups and tech vendors. The US-based organization Thorn, which literally sells the exact scanning software in question, spends hundreds of thousands of euros lobbying in Brussels. The tech industry has officially lobbied side-by-side with NGOs for a law that ensures their profits and data access, rather than protecting children."
