Why doesn't Windows ship with an unarchiving utility?
I think that at least since win10 there is zip embedded in windows, it’s just not 7z

there was a German startup (Sono Sion) some years ago that had a very similar idea and had even prototypes [0], but they filed for insolvency 2-3 years ago. Now I think they pivoted to something more boring and practical - putting solar panels on vehicles. I hope aptera gets to production though

> Classical Electrodynamics by Jackson (essential). This is the bible of classical electrodynamics, and everyone who works through either loves it or hates it (I loved it).
I agree that there is a division between who loves that book (like the author) and the majority of the graduate students who had nightmares (and sometimes still gets). I like this goodreads review of the book [1]
> A soul crushing technical manual written by a sadist that has served as the right of passage for physics PhDs since the dawn of time. Every single one of my professors studied this book, and every single one of them hates it with a passion. While I've no intention of becoming a professor, I still wonder, will my colleagues also inflict this torture on their students? Will the cycle be perpetuated ad infinitum? How many more aspiring physicists will we leave battered and bruised at the gates of insanity before switching to a textbook that seeks to make electrodynamics clear and intuitive rather than a mind-numbing trip through the seventh circle of hell?

* personal note: If this book is really the bible of classical mechanics, then I'm atheist.
It is interesting that 2 years later the same reviewer changes their mind a bit:
> Now, a few years after writing that review, I must return to say that as much as I hate this book, it's probably the best textbook that I have. I constantly return to it to reteach myself basic concepts or math. The problem with the text is that in order for it to be useful, you pretty much have to already understand the material. It's a dense, technical manual that, when paired with an easier to understand text such as Griffiths, grants tremendous power. Don't get me wrong, if there is a hell, I personally hope John David Jackson is burning in it right now, but I also have to tip my hat to him

It omits the obvious. How can one download this and try at home?
maybe part 1 of it will help

MCUs with just 4MB of RAM may not even have IP based networking.
on NXP K60 with FreeRTOS and lwIP IP based networking runs without problems with 256k Flash and 64k RAM. Of course it depends on the application, because the throughput is not high, but that is not the point here

Something I never understood about embedded systems work: why is the pay so bad?
Maybe I was just looking at the wrong job listings, but the technical difficulty (relatively low-level programming, manual memory management, dealing with janky firmware, antiquated toolchains, and incomplete documentation) seemed much harder than the compensation being offered.
At least in comparison to other types of coding you could be paid to do.
The only answer I could come up with was that unit profit margin * sales volume imposed a much lower cap, relative to pure software products?
I have thought about this myself. I do not think it is directly related to China. I think it is just not trendy to be an embedded developer. And the reason is that it is extremely difficult to start a hardware company (even more with the chip shortages in the last 2 years) because one needs to take care of delivering components that are rare or not available for months, to create the firmware for the board, to manufacture it and deliver it to the customer. Working from home office is often not possible, because soldering stations are needed, oscilloscopes, power supplies etc. The tools are also often not cheap, a debugger can cost 10-15$, but often for bigger projects the debuggers are 100x more expensive, the compiler could also cost a couple of thousand dollars. Then if there are bugs in the SW (there are always bugs) it is again difficult to update the software (this has improved in recent years with all the connected devices/cars etc., but it is still difficult). And as far as I know there are not that many hardware companies that have big exits.
On the other side, being a web developer does not require being in an office, buying expensive hardware and tools, nothing is physically delivered and at the end there is a chance to be part of a big tech exit. Big exits -> big salaries
jore commented on Gas tanker hit by super-yacht sinks off New Providence tribune242.com/news/2021/... · Posted by u/colinprince
Does it create a problem that other boats can't tell which rules a motor/sail boat are operating under?
In other driving rule systems, it's important that everyone can predict everyone else's proper behavior.
My instructor told me that the size is what matters often in real life. He was sailing a 45 foot yacht from Europe to South America (ARC race) and in the middle of the Atlantic Ocean they were very close to hitting a huge tanker. They were with sails at night, but the tanker was not willing to change course for such a small boat so around 50m before the impact the sailing boat changes course. All the time they were on the radio talking with the captain of the tanker, but they could not persuade him to change course. And for them this is a race so they always wanted to follow the optimal course, therefore they were reluctant to change their course

It can. Here's an example of using Plover (now part of the openstenography project it seems):

(I know this is not the only presentation in the existence but it's one that I found; there's one by the author of Plover within some longer presentation about it.)
Honestly, doesn't seem super fast to me :-).
thanks, it also does not look fast to me and does not seem to improve the process the way it does for speech. Additionally I guess there is a steep learning curve so it is definitely not for everybody
jore commented on Open Steno Project – Freeing stenography openstenoproject.org/... · Posted by u/pabs3
can stenography be used to write code? or is it only for text based on speech?
