Tech news

33 years ago:
I had just started reading a book on the open-source revolution two weeks ago (Rebel Code by Glyn Moody), which begins with the stories of Stallman and Linus, and so how GNU/Linux came to be. Quite interesting, if sometimes a little soporific about less interesting topics.

BTW, I still don't see any ads. Perhaps that's because I use Stardock's Start 11 menu.

pibbuX who is still considering switching to linux (eventually) for every day use, excluding gaming (and at the moment also his hobby programming).
I read a similar article, and it's apparently not in the main releases yet. I hope it'll be possible to disable this atrocity.

If it wasn't for the games, I'd be much closer to the switch to Linux.

Quantum-based navigation is on the way!

It's a very precise Inertial Navigation System, or INS, which was the system used on ships, aircraft, and spacecrafts before satellite-based GPS replaced them. It's still big, but so were the first mechanical INS systems (like the early prototypes of Apollo's Inertial Measurement Unit which were tested on a B-29 by the MIT Instrumentation Lab).


You may find articles talking about 'quantum compass' from journalists who prefer simple words. This has nothing to do with a compass. INS devices track their displacement from a continuous measurement of their acceleration. If you feed it a correct initial position, it tells you where you are, even after moving around a lot.

The indication tends to drift with time, so you need to re-align the position after a while. Some fighter aircraft like the Mirage 2000 allowed pilots to do that just by pointing at a known landmark on their display. Pilots set a number of calibration landmarks when they were doing their flight plan to make sure their bomb hit the right target. Other aircraft, like the B-52, had an astro tracker, which uses the position of the stars to recalibrate the INS when they are were visible (it was also used on some of its missiles). I think the Apollo spacecraft also had a similar sextant device to re-align its INS.

Boeing was a great company, but its professionalism has been seriously declining since it merged with McDonell Douglas. Why is NASA still doing business with them?

I suppose they want a bit competition between private actors. Admittedly Boeing doesn't seem to compete particularly well.

"And I’ll acknowledge that we have some work to do there. It’s pretty natural when you’ve had a difficult decision to make.” Bowersox said that NASA remains “committed to working with Boeing.

Stich weighed in, saying, “Boeing did a great job building a model. The question is, ‘Is that model good enough to predict performance for a crew?’” He added later, “There was just a little disagreement in terms of the level of risk. And that’s kind of where it got down to, and I would say it’s close. It’s very close; it just
depends on how you evaluate the risk. We do it a little differently with our crew than Boeing did.”

I think the quote is a polite and diplomatic way of asking them to go down to mr Toby, to the place where nobody are freezing but wish they were. (And the coffee is cold.)

So, apart from mr Musk, who's next?

EDIT: Multiple edits. Sorry.

pibbuR who for instance doesn't use cruise control due to disagreement with the car on safe speed in curves, narrow roads, oceans, etc,
Count me as someone else who doesn't agree with everything a car has to offer, especially when it's only to contradict the driver.

I also prefer some things to remain analogue (and reliable), like physical buttons and knobs instead of touch screens and hydraulic steering rather than electric. :)

Fortunately my 1 year old has button for everything I need to operate the car, in addition to the touch screen.

What I do like are the blind-spot detectors, and the warning if I deviate from the lane I'm in (without blinking). Also the indicator on the side-mirrors (correct English?) that warn if a car approaches from behind in the blind zone, in case I do want to switch lanes. A camera for reverse driving is also handy.

The car reads traffic signs, and from that display the speed limit. The indicator starts blinking (faintly) if I'm driving above said limit. I would have preferred if it was possible to also turn on a warning sound. There is BTW a slight problem when I start driving, and there are no traffic signs nearby. Sometimes, like when leaving a parking field, it suggests 80 kph. But in general it's very reliable.

As I've said, I don't use the cruise control. To be honest. that's because around where I live there are mostly 50 kph and below zones, with speed limits varying frequently (lower near schools, kindergartens and so on)

Another thing I don't use is the mobile app. I don't see the need for it, and I don't see the need for sharing personal information with Opel. They claim that the GPS works better (more updated maps) if I connect the phone, but it's good enough as it is (and I very rarely drive outside my comfort zone anyway). I have used the app a couple of times, but only to turn on heating 10 minutes before driving, handy during winter. But not essential - the heating equipment is very efficient and fast - I assume that's typical for electric cars.

pibbuR who most of the time moves at 6kph, except when on his in door exercise bike (25-30 on-the-spot kph).

PS. Talking about reliability. My previous car suddenly refused top reverse. Just out of the 5 year guarantee period, and fearing an expensive repair, we decided to replace it (had thought about that for a while). Turns out they fixed that problem through a software upgrade. So we really didn't need to buy a new one, but then we had already almost decided to do that anyway, so it's no big deal. The new one has so far been very reliable, we're quite happy with it. DS

PPS. Young men often like to fix and improve things on their own. I don't think that's possible anymore, due to all the electronics and the software. BTW, I also liked to do things like that, but with very little success. After installing extra lights, driving 300 km on roads without street lighting at night in the north, only able to use near light (probably not correct English), because the fuse burned out whenever switching to ... eh .. far light was not much fun. DS.

PPPS. We were going to Tromsø, to catch a plane to Bergen the next day, planning to stay the night at my in-laws. We arrived there severely delayed at around 2-3 o'clock in the morning. And then the 10 months old youngest one, suggested that maybe it was time to get up now. Ouch! Fortunately, a gentle push down into her bed and comforting commands was good enough. Puh! DS

The extra sensors are great, especially for everything hiding in the blind spots, yes.

Sometimes I appreciate the cruise control that sets the maximum speed, which relieves me from checking my speed all the time in town. But it's indeed a little distracting to set it up, especially if the speed changes too often.

It would be a shock to get back in the first car I owned. No ABS, no airbag, no AC, no steering assistance, no GPS, ... Nothing non-essential, except an analogue radio and a tape destructor player (and I had to install it myself). Almost no engine, either.

My father had such cars, and I was driving them when i needed them. He used up a lot of cars because he was working a few hundred kilometres away and came back to us family only for weekends or for vacation.
One of my most scariest moments was that when it was utterly cold, and the "turbo" steering assistance of the latest car of my parents was effected by the minus temperatures (Celsius, that is). There simly was no more steering assistamnce - and no brake assistance, either !
I still do miss the tape player. That was so great, driving with the music I loved !

Now that's sad. :( I was never following them, but news from that site were posted elsewhere regularly.
