Yay, I now have running on a PYNQ-Z1 FPGA board. It has a 650MHz dual-core Arm Cortex-A9 with 512MB RAM. That is not enough memory to run though.

Fediverse, is anyone aware of some technical projects that could use developer-facing documentation written over the next couple days? I need to make new technical writing samples for a position I applied for. Sadly the stuff I've previously written is all either long-gone on previous employers' servers, end-user documentation, or otherwise unavailable.

Ok, now getting into cooler stuff

Snow geese!

They don't even live here, they are just migrating through. There were several flocks of them SO high up, bright against the blue sky, dark against the white clouds.

I had thought they were just canada geese catching the light, and I didn't realize until later they were something different... I wish I'd tried harder to get a good picture.

Explaining how embedded development works: you can't use most tools you're used to in any other environment. Such as, if you have to work with something like AWS and you have to use C or C++, you'll have to write your own implementation of even some hashing algos if it's not used much elsewhere. Sometimes some libraries you can use exist, sometimes they don't. In this case, openssl has some low level implementations, but can't be used on an embedded OS-less device. The AWS SDK can't be either.

In Osona Sud, Catalonia the distribution of Guifinet nodes is superdense. It's like the William Gibson saying that the future is here but not evenly distributed. Some areas of the world are already living in the future of decentralized user-owned network infrastructure.

If anyone says that mesh networks are impractical or don't scale to a municipal level then Catalonia is a good showcase of it working. Obviously not all of these thousands of nodes are highly tech-savvy anarcho-hackers, so this is something which can work "for the people".

@dildog William Gibson himself agrees

"Much of the planetโ€™s human population, today, lives in conditions that many inhabitants of North America would regard as dystopian. Quite a few citizens of the United States live under conditions that many people would regard as dystopian. Dystopia is not very evenly distributed."

So I'm moving up to Edinburgh in the next three months. Do I know anyone connected on Masto who lives up there? :)

Would love any advice you have!

@kaniini Day ONE

A hacker comes into a restaurant and discovers that the salt shaker on the table can be unscrewed and one can pour anything into it. The hacker goes home and writes an angry letter to the manager of the restaurant: "I, meG@Duc, found a vulnerability in the salt shakers at your restaurant. An attacker can open them and pour poison inside! Take action immediately!"

Day TWO
The manager, among other business letters, requests for food deliveries and courier receipts finds the notification letter and shrugs: "Who could even come up with this nonsense?"

Day FIVE
The hacker comes into the restaurant and pours poison in all the salt shakers. Three hundred people die, the manager is dragged three months in courts to prove the absense of a crime. The Hacker writes a letter in the style of "Well, I told you!".

Day 96
The manager orders his staff to buy specially designed salt shakers with a combination lock. Visitors of the restaurant feel like they are missing something very important in the meaning of life.

Day 97
The Hacker discovers that the holes in the salt shakers pass salt in both directions. And not only salt, anything! He writes an angry letter to the manager after pissing in all the salt shakers. Three hundred people stop visiting the restaurant forever, thirty get admitted to the hospital with food poisoning. The hacker sends an SMS to the restaurant manager: "How are you doing?". The manager is dragged through courts for three months and is released on probation.

Day 188
The manager vows to no longer work in any kind of food establishment, and to peacefully cut timber in Siberia. Engineers are working on a new one-way valve for a salt shaker. Waitresses in the meantime withdraw all the old salt shakers and distribute the salt by hand.

Day 190
The Hacker steals a salt shaker from the restaurant and carefully studies the device at home. He writes an angry letter to the manager: "I, meG@Duc, stole the salt shaker and I find this fact outrageous! Anyone can steal your salt shakers!" The previously fully sober manager goes home and drinks a bottle of vodka.

Day 193
The Hacker discovers that all the salt shakers in the restaurant are chained and nailed to the table. He arrives at a hacker conference and reports on his progress, getting a well-deserved reward for the protection of the interests of society and consumers. Fortunately, the manager never hears anything about it and will not die of alcohol poisoning, for now.

Day 194
As part of a diabolical, genius elaborate operation, BLACKHAT hackers break into the restaurant and pour all the salt from the salt shakers in their pockets. The Hacker meG@Duc writes an indignant letter to the manager, alluding to the fact that there is no concern for the visitors in the restaurant as any criminal can deprive honest people from salt in an instant. A salt dispenser with a one-time authorization is just necessary!

Engineers work in sweat on a new salt shaker, while waitresses hand out salt manually, again. The manager goes on vacation to the
Seychelles and has dinner only in his room, avoiding any canteens, restaurants and bars.

Day 200
Visitors of the restaurant find in horror that in order to pour salt, they must go to the waitress, show their passport and get a special 8-digit one-time code to the shaker. For pepper they should repeat the procedure.

This is the 737 max, the new model of the 737 that was involved in two crashes recently. As you can see, the engines are mounted further to the front and not in the center of gravity of the plane. Why?

The point of the redesign was to use bigger engines because they are more efficient. But putting them under the wings was not possible because the plane was not high enough.

You could say 'why not just make the wheels taller then', but that's not possible because then you'd have to re-certify the plane because it wouldn't be a 737 anymore.

Now, having the engines so far up front leads to the problem that accelerating will make the nose point up, so there's a risk of a stall. To prevent that, Boing 'fixed it in software' by adding an automatic system that starts pointing the nose down automatically in some situations.
