Yeah, 24 years old. It’s crazy how little has changed in 24 years, other than most of the major sites now supporting IPv6 (with some notable exceptions, such as AWS and GitHub).
Once upon a time in the 90's I was at work at 2am and I needed to implement a search over a data set. This function was going to be eventually called for every item, thus if I implemented it as a linear search, it would be n^2 behavior. Since it was so late and I was so tired, I marked it as something to fix later, and just did linear search.
Later that week, now that things were working, I profiled the n^2 search. The software controlled a piece of industrial test equipment, and the actual test process would take something around 4 hours to complete. Using the very worst case, far-beyond-reasonable data set, if I left the n^2 behavior in, would have added something like 6 seconds to that 4 hour runtime.
(Ultimately I fixed it anyways, but because it was easy, not because it mattered.)
I don't pretend to understand the thermodynamics of all of this to do an actual calculation, but note that the ISS spends half its time in the shadow of the earth, which these satellites would not do.
The earth is actually a pretty big heat source in space. Solar radiation is a point source, so you can orient parallel to the rays and avoid it. The earth takes up about half the sky and is unavoidable. The earth also radiates infrared, the same as your radiators, so you can't reflect it. Solar light is in the visible spectrum so you can paint your radiators to be reflective in visible wavelengths but emissive in infrared.
Low satellites are still cooler in the Earth's shadow than they would be in unshadowed orbits, but higher orbits are cooler than either. Not where you'd want to put millions of datacenters though.
You would put these in polar orbits so they are always facing the Sun. Basically the longitude would follow the Sun (or the terminator line, whichever you prefer), and the latitude would oscillate from 90°N to 90°S and back every 24 hours.
No. Otherwise how would you power them? We could use nuclear power methods, like we did in the Voyagers for instance. But the press release doesn’t mention that and, for a constellation of satellites around the earth, it would be a terrible idea.
> GNU Unifont is part of the GNU Project. This page contains the latest release of GNU Unifont, with glyphs for every printable code point in the Unicode Basic Multilingual Plane (BMP)
Still doesn't exactly say what it is? I get that it's glyphs for printable characters, but honestly it could be a PDF, video, collection of PNGs or SVG files, an Adobe Illustrator file, a linux distribution, a web browser, or pretty much any other piece of software or data format. I presume it's a TTF or OTF font file?
no.
as others have stated too, the following should be mentioned
- what's the 2 meaning in BMP
- it's designed as a monospaced (or proportional?) bitmap font
- designed in a single 16x16 size only (or also 8x16? it's a bit unclear)
- provided as an OTF/TTF font format, which can be scaled by most font rendering engines to other sizes, but u need antialiasing to make it look smooth (this is mentioned, but under the download section only)
- use as a "last resort" default font, according to wikipedia at least
