Well, except for the time their datacenter caught on fire I haven't had any problems.

If you look at the datasheets, the SoCs in the Miyoo handhelds were originally intended for dashcams. I don't know whether these handhelds emerged as a result of excess supply of chips like the RPi or simply it was the cheapest alternative that fit their needs, however.

There are multiple grades of stainless steel, which have different proportions of metals in the alloy. The stainless steel used in the cybertruck's body panels appears to be 301 grade, which is not among the best in rust resistance, and can indeed rust depending on environmental conditions.

Given that 301 stainless is cheaper than 304 or 316, which have similar mechanical properties while having better rust resistance, I would guess that material costs resulted in choosing 301 for the cybertruck.

My metallurgy is a bit rusty (sorry), so take this with a grain of salt (which 301 does not resist well, incidentally!).

Yes, but compared to the setup for equivalent satellite services it is very cheap. The Inmarsat antennas need active compensation and they sit inside big radomes, while the Starlink antennas are smaller and do not need to move thanks to being phased arrays.

The bandwidth, latency and stability that Starlink has is also leagues better than geosynch based solutions, for a much lower monthly price.

Even without considering the better performance, the price makes it viable now to have a internet connections in places it did not make financial sense before.

516 people in Spain with Farto as first surname, 485 as second surname. None with both. Quite rare. You can check distribution out yourself in a map with this neat tool from the Spanish Statistics Institute https://www.ine.es/widgets/nombApell/index.shtml

As an aside, I spent some days last week around that zone and found out about the existence of the surname Pis, which has a similar distribution and rarity, and is even more unfortunate since it means "pee" in Spanish. At least Farto is only funny in English.

Since in Spain you get your first surname from your father's first surname and your second from your mother's first that sometimes also leads to unintended hilarity in names (example, real person, Luz Cuesta Mogollón, which roughly translates to "electricity costs a bunch"!)

In addition to that, this photo was taken onboard a cable laying vessel. There are not that many and they are booked back to back all over the world, so it is not of the question that they would have dual metric and imperial measurement devices. Also, onboard a working ship there is usually an international mixture of crew and contractors, and of course they might have American clients.

Yes, but Portugal had colonies in India!

If you don't intend to keep them fully stock there are modern solid-state drop-in replacements for reasonable prices! Given that they are fairly simple cars building one yourself from common electronic parts would not be too difficult either.

Norway is an interesting case regarding government provided services. Easy procedures, clear documentation, but then anything needing human review tends to take exactly six weeks for an answer.

I am partial to 48sx in Android, I find Droid48's UI somewhat uglier.

Also, to answer OP's question: I use the HP48 emulator in my phone very frequently. I have a solar folding 4-key Casio on my work desk which I also use since it is less distracting to fold it open and do some quick calculations there instead of opening a Python interpreter or the scientific calculator app on the computer.

I studied industrial and electronics engineering at university so I have used and abused several Casio fx-82, they are ubiquitous in Spain starting from high school. At uni, I bought an used HP 50G which saved my ass in more than one exam, being able to store equations and having only to input the coefficients saved a lot of time and errors. The programming capability and symbolic math were also very handy when dealing with big matrices. I remember turning a long and messy electronics nodes problem that took half an hour or more to solve by hand into a short program that solved it almost instantly for arbitrary matrix sizes. Having to program my own solution also meant learning the procedure in the process, of course! Not cheating!

I have been meaning to build a lithium battery pack for my 50G, it is true that it eats batteries. I used to buy a new pack before exams just in case. I have a bunch of harvested li-ion cells from disposable vapes that would fit the bill perfectly, just add a TP4056 module, a regulator and some CAD work for a printed enclosure. And a bit of free time, of course.

Curiously, here engineering schools are (were?) partial to HP calculators, TI are not as common to see. My boss still has his 48G on his desk and uses it frequently. I guess it becomes second nature when using it so much during formative years, and I definitely did. Being fast and precise on your calc could bump you from almost passing to barely passing.

There is an interesting take on this on Neal Stephenson's Termination Shock: wealthy people can afford to have personal curators that filter news and other content for them, while the lower classes have been driven off the deep end by the near future Internet's relentless stream of disinformation.

I think they did: there is a mention at the end of the article as how they lost a camera during a test and they are trying to piece together the footage they could salvage.

Lately I have been trying to improve performance of a high precision RTK GNSS receiver installed somewhere high up on the Barents sea, near the Russian border with Norway. Some days it works perfectly down to cm accuracy, but other days it is not able to hold an RTK fix at all.

I was suspecting the northern lights were to blame for most of this trouble since the bad performance periods more or less track to high Kp periods, but it seems that it may be man made interference... There are recent reports from planes flying routes over that area about bad GNSS reception, and efforts from NKOM to log conditions with mobile antennas.

It's probably happening already.

It seems there is enough pushback from Microsoft's enterprise clients because the W10 LTSC versions lack all the adware and most of the spyware that is pushed on the regular versions. Of course, they are not advertised anywhere and buying licenses through regular channels is impossible for a home user or a small company.

I haven't compared resource usage between my previous W10 Pro VM and my current W10 LTSC VM but it seems to start up much faster, and of course the aggravation from using it is way lower.

I was hoping for CFD applications myself when I saw the headline... Is there any progress on that direction or is it even possible?

That is the ADHD. Constantly changing the topic to talk about something that happened to you once which you were just reminded of because of a detail in the conversation. Too much sharing of personal details with people I maybe just met. Telling too much to someone in spite of knowing that I should have shut up.

It has taken me ages to be fully aware that I do it, and when I notice I try to stop myself from derailing the topic being discussed. If I feel that it is truly relevant I cross my fingers or something like that to add it at the end of the conversation, but usually after a few seconds it loses the urgency and I feel I can drop it, or even forgetting what I wanted to add at that point. It is absolutely a social problem and I know people see it as a flaw of character, but it is slowly getting better. Being gently reminded that I am doing it helps because sometimes you just don't notice.

Of course if your acquaintance is on a too high dose of Vyvanse or has been wrongly diagnosed it can cause a bad case of motormouth, as all stimulants do...

I have only been offshore once, in the Goliat platform, for a mooring monitoring system installation — I was definitely not expecting the cruise ship like crew quarters! Single cabins with ensuite bathrooms, a cozy dining room with wall to wall windowing, even a pool table!

Goliat is a very modern FPSO design, however. My colleagues' experiences in other floating rigs around the world, which are usually built from converted tanker hulls, are more like what you describe, especially below the equator. For contractors you might be lucky and get a double cabin to share, but cabins might have up to four bunks. Definitely don't forget to pack some flip flops or crocs for the showers!
