> Considering that the linux kernel is strongly tied to the specific C dialect supported by GCC and is not portable at all, this argument is bullshit. Linux has been ported to over two dozen architectures so it is extremely portable. Yes

I think you hit the nail on the head. It seems like organizations having equal paternity and maternity leave would level the field a little too.

IC vendors do terrestrial radiation testing on their parts and get upset rates. For example: http://www.koszek.com/papers/zynq_protons_r7.pdf

What a misleading chart. A lot of this discussion about solar reminds me of the peak oil discussion that happened around 2005. Oil is tanking due to US non-conventional oil and fracking. I think natural gas power generation will be relevan

Yeah for cargo I agree. I was thinking more along the lines for human rating. Propulsive landing helps for some failure modes but not all. Like I don't think it would have helped the CRS-7 failure had that been manned.

It seems like there is a wall in reliability with getting chemical rockets much more reliable than about 99% - 99.5%. SpaceX and Blue Origin are doing cool things, but I don't see them being any more reliable than previous generations

To be fair, for iOS development, you need a Mac and it is closed source as well. One would argue that Microsoft is closer to Apple than it is to Google. And Android is not a 100% open source stack, parts of it are closed source.

I love the markdown to PDF converter using embedded LaTeX for math expressions. So much easier than writing pure LaTeX and you still get a beautiful result.

I have relatives in the rural Dakotas who don't really need to lock anything up. I went to college in Atlanta, where leaving anything slightly valuable inside your vehicle would lead to a smashed window. So I've developed a lifelo

I think a lot of the problem is you would radiate like crazy, causing harmful interference. The same thing happens with power line data service.

Can you foot the bill for bringing it another mile down the road? I know you can do that for electric utilities and water to rural land, not sure about phone/cable.

The US National Map has better, more recent topos. These GeoPDFs allow turning on/off layers (e.g., satellite image, PLSS grid lines, etc). You can also download historic topos. http://nationalmap.gov/ustopo/

Recently I had to do some work on a small embedded system. During development, we had an Ethernet port with associated magnetics on a riser board. But once it went to production, we couldn't fit that so there was only a UART serial por

Should have had your supply chain people push the vendor/distributor on price of the half code space part to make all of that cramming NRE worth it. ;-)

>Self-driving cars, for example, must have infinitesimally precise location data to avoid accidents. I'm sure surveyors, machinists, and physicists would be interested in how "infinitesimal" location data can be obtained.

That doesn't make any sense to me either. To avoid accidents - do they mean so the car doesn't drive off the road when making a turn? Surely the car uses visual feedback as well.

There is a growing market for small spacecraft to be able to point very accuratley (as in 10 arcseconds or so). Blue Canyon Technologies XACT is attitude control in a box for a Cube Sat - star tracker, reaction wheels, torque rods, magnetom

Typically, a spacecraft will have reaction wheels or CMGs to generate internal torques which let you change attitude by the conservation of angular momentum. However, there are also external torques in the system. In low Earth orbit, you ge

by planteen 10y ago
You aren't going to have much agility with torque rods. A small satellite can move a few degrees per second with reaction wheels. A large spacecraft needs CMGs to get the same slew rate.

Exactly. That's why in Denver you see lots of old houses getting purchased only for their land, torn down, and then a new $800k house in their place.
