I do custom electronics, robotics, and embedded software development - I specialize in quickly turning ideas into prototypes. I've built custom automation equipment for chemistry labs, sensors that are in use in household/utility applications, control circuitry for construction equipment, 3d printing electronics, data acquisition equipment. No project too small. Few projects too large. Deep discounts for open source hardware work.

I would also be happy to come over (anywhere in Europe) and teach any of the above skills to a small group of interested people. I've taught courses in electronic assembly (SMD), 3d printing (building/using printers, iterative 3d model design using programming) and robot design and construction. I've taught courses at several universities, hackspaces, and conferences.

Sorry about the orange tint on the slides, I forgot to turn off the redshift function in KDE and the talk was late at night.

Nuclear plants need to be switched off for weeks/months at a time for the following reasons:

- refueling (regularly done, highly plannable)

- insufficient cooling water/ too warm cooling water (regular, seasonal, not very predictable short-term)

- planned maintenance (often combined with refueling)

- unplanned maintenance (accidents)

Whenever these things happen, the entire reactor is producing no power. This is why most nuclear facilities have multiple reactors, so you can rotate these tasks among them and still have some power. Unfortunately, the cooling issue is becoming more and more of a problem, and many sites that used to operate year-round now have to scale down significantly in mid-summer due to lack of cooling water.

There are many ways to improve the speed and accuracy, but it's really important in settings like these to not make changes until the input method is fully reliable, because there's the risk of complete loss of communication.

The full event streams have been published this time around, including the failed sessions. I recommend reading the article and watching the videos of the system operating - they have a video of the input calibration/training, and another video of the longest session. The sessions are few and many days apart, and not all of them demonstrate successful control, but on the days where the patient can successfully drive the system there is no doubt of the communication method's authenticity, and the researchers have no input or interpretation capability.

The previous controversy around the researchers is not about them scamming patients, it's about them publishing only the positive results of their work and not disclosing negative results, making the average success rate appear better. This is one reason they publish full event streams and list days with no attempts and failed attempts extensively in this paper. The code has also been published, and the raw potential recordings are available on request. I had a careful read and I can't find anything methodologically problematic in this publication. When you watch the video, be aware this is the longest and most successful session, and the researchers made this very clear.

> I cannot imagine cooking with fewer than 3 rings.

You're allowed to own more than one standalone induction plate. And you're also allowed to position them freely over your work area :)

Get a standalone induction plate. They're cheap and portable and they let you try it out without a huge expense. I do 90% of all my cooking on a single induction plate I paid ~$60 for. Non-induction electric hobs are trash, and induction is much closer to gas, but more controllable, less messy, and less dangerous. That said, I would strongly recommend against a builtin induction hob. They're expensive as fuck, and eat lots of counter space. The standalone induction plates are amazing, much nicer to work with, and cheaper, and you can put them away when you need the extra space. Restaurant supply shops have standalone induction plates for ~3x the cost of the consumer ones which are phenomenally good, that's what the higher end new kitchens are going for.

I understand Russian. Looking at ria.ru over the past few days there is barely any mention of the war, certainly no details, there's much more mention of sanctions but only some weird stories about their origin and motivation.

"The Ugly American" has been claimed to have been an enormous wake up call to how the US does foreign policy. It allegedly motivated much of Kennedy's approach and was responsible for the formation of the Peace Corps. Before he was elected, he bought a copy for every sitting senator.

It means if you move to a different country you can probably keep your email, but you will probably lose your phone number.
