I made one a couple years ago to watch the clouds sail cross the sky. After a few weeks I noticed scratches in my acrylic dome. On review I have some nice picture of the feet and claws of juvenile bald eagle. Sacrifice a bit of your horizon

You can't really bang bits like you can with carefully cycle counted code on something like an Arduino, but you can put all your bits into a good sized buffer and use DMA to push them out a stable, hardware clocked rate. You still have

The WHO rationale on masks includes not emboldening people to go out in less than effective masks. Isolation is better at stopping the spread than slightly slowing the spread with masks. It’s also worth noting that there isn’t a straightfor

I propose: LEO satellites are not a problem for astronomy. • Atmosphere distorts observations. • Astronomers do not like distortion. • Astronomers like dark backgrounds. • For a satellite to be illuminated, it must be visible to the sun.

Speaking to the 13" iPad w/keyboard combo, a MacBook Pro 15", and desktop multi monitor Macs which I use for working… The desktops are the thing for writing code. This goes for iOS apps, Mac apps, or Posix type server systems

The app might be implementing the paste function. The most common use case of copying and pasting text could probably be hidden inside the standard text fields, but consider images, sounds, or custom data types. The app needs to grab these

Venus still rotates. It rotates on it's axis very slowly, every 243 earth days, and goes around the sun every 224 earth days. Its direction of rotation is opposite ours, so when combined with the orbit you get a sunrise every 117 earth

Of the $29k in repairs, over a quarter of it is just periodic new tires yet they don't break that out in the article. I was saddened to see that key fobs are about $150 (and he needed 6 of them). That's the kind of pricing jackass

Consider a VT100. It could only go up to 19200 baud… The VMS manuals suggested that system administrators may want to keep the hard wired terminals down to 2400 buad and hide the fact from users by turning on "smooth scroll" (wh

Australia is clipping along at 2.7”/year (about 1/16 of a meter). That doesn’t seem like much, but in a few decades your hole is going to need to be pretty big.
