You can do quite a bit with timing on the launch vehicle. A delay of ~45 minutes in SSO is the opposite side of the planet. And do any of the Planet CubeSats even have propulsion? It looks like the Flock constellation deployed without it.

Good luck protecting yourself against a state, even if you are a billionaire. You have to sleep somewhere and protect your assets somehow.

Electron can launch many CubeSats at once with a dispenser. So saying it can't do CubeSat class is not correct. This is what the upcoming NASA ELaNa XIX is doing: https://www.nasa.gov/content/upcoming-elana-cubesat

The M1 (Crab Nebula) pulsar slows by 38 ns per day. But it is very new, less than 1000 years old. https://en.m.wikipedia.org/wiki/Crab_Pulsar

Cool article. The future was correctly predicted here - this is how modern graphics works: "I've had discussions with people that suggest that an accelerator for Pixar's Renderman architecture is possible. (This is the techno

In Linux, yes, there is a service called mcelog and a utility from the edac-utils package called edac-util. You will see correctable ECC errors on systems. How frequent honestly seems to depend on the workload and the system itself. My susp

It seems like there's another factor of altitude or maybe humidity that makes a difference. In my experience, Atlanta is like you describe - a handful of stars and planets. But in Denver, which is colored the same as Atlanta, I can eas

This happens sometimes. For example, GPS and DMSP (Defense Meteorological Satellite Program) had many blocks of identical satellites. One of the DMSP spacecraft will never launch and has been ordered to be scrapped, since it is now so out-o

Companies spin-off like you are describing too. Except the market there is rational, as in, the market cap of the two split companies is equal to the previous market cap of the unsplit company. Look, for example, at Hewlett-Packard over the

You've piqued my interest about your VR space. What sort of dedicated VR space do you have? What kind of VR content do you watch mostly - is it traditional 2D movies or 3D/VR movies?

Drop the bucket and look at the equatorial bulge problem of a planet stated in the article. The planet is effectively spinning in a vacuum so there is no "outer friction."

I totally agree with you and so does Rob Pike: https://commandcenter.blogspot.com/2012/04/byte-order-fallac...

I worked on a code base using the LEON (SPARC, big-endian) and also ARM in little-endian mode for space. The code was common for both endians. I followed the sage advice of Rob Pike on it: https://commandcenter.blogspot.com/

When I used Vivado a couple years ago on the Zynq, I was shocked by this. It was supposed to replace ISE, but was equally bad at version control. Absolutely ridiculous.

I'd say the congestion in Denver is less than Atlanta, DC, and Boston. Those cities are all front runners as well.

Nice small mountain towns, especially those near ski areas, are expensive. But towns and cities on the plains (e.g., Ft. Morgan) are pretty inexpensive. And southern Colorado cities like Pueblo and Colorado Springs are also a lot more inexp

Denver isn't gaining 10K people a day - that would be insane! This article says 13K people in a year to Denver city & county: https://www.denverpost.com/2017/03/28/denvers-growth-spurt-s... It looks

Calling it brute force isn't quite right. There is an efficient algorithm for prime determination (Lucas-Lehmer primality test) on Mersenne Primes (numbers of the form 2^p-1). https://en.wikipedia.org/wiki/Lucas–Le

That list is a bit under-specified for an absolute newbie to electronics. A link to Digikey or Mouser would be helpful. A resistor just isn't a resistor, for example. I imagine they really mean a 1/4 watt 5% tolerance thru-hole re

I had the same thought - headlights are a very weak link in a minor accident such as a collision with a deer or low-speed rear ending. If the cost of replacement goes from $100 to $1000, that's a big deal!

Just read the Wikipedia, looks like you are trading one hardware bug for another on the Quark. At least you know when a segfault happens I guess. "Intel Quark SoC X1000 contains a bug #71538[11] that "under specific circumstances&
