Byte ranges are the only way to access files over sftp. Look at the read and write requests in https://datatracker.ietf.org/doc/html/draft-ietf-secsh-filex...

I agree but there are legacy daemons that do not follow the spec. Most here will never see them in their lifetime but I had to deal with it in the financial world. People would be amazed and terrified at all the old non-standard crap that their payroll data is flying across. They just ignore the range and send the entire file. I am happy to not have to deal with that any more.

This article assumes that no extra mass is needed for cooling, i.e. that cooling is free. The list of model assumptions includes:

• No additional mass for liquid cooling loop infrastructure; likely needed but not included

• Thermal: only solar array area used as radiator; no dedicated radiator mass assumed


Author also forgot batteries for the solar shade transition period and then additional solar panels to charge these batteries during the solar "day" period. then insulation for batteries. Then power converters and pumps for radiators and additional radiators to cool the cooling infrastructure.

Overall not a great model. But on the other hand, even an amateur can use this model and imagine that additional parts and costs are missing, so if it's showing a bad outlook even in the favorable/cheating conditions for space DCs, then they are even dumber idea if all costs would be factored in fully. Unfortunately many serious journalists can't even do that mental assumption. :(


I'd say int makes much more sense to just shut off in the sunshade. The advantage of orbital solar, comes not so much from the lack of atmosphere, but the fact that depending on your orbit, you can be in sunlight for 60-100% of the time.

That proposal I've seen a few times too, basically put up a constellation up there, linked with laser comms and then transfer data to the illuminated sats in a loop. That sounds possible, but I have doubts. First of all if we take 400 km orbit, the "online" time would be something like 50 minutes. We need to boot up the system fully, run comm apps, locate a peer satellite and download data from it (which needs to be prepared in a portable form), write it locally and start calculations, then by the end of the 50 min repeat. All these operations are slow, especially boot time of the servers (which could be optimized of course). It would be great if some expert could tell us if it is feasible or not.

Yeah that's just flat out wrong then: you can't use the solar array as a radiator.

Of course you can. You can use everything as a radiator. Unless you have something which is literally 0 Kelvin everything radiates.

See here for all the great ways of getting rid of thermal energy in space: https://www.nasa.gov/smallsat-institute/sst-soa/thermal-cont...


You can use everything as a radiator, but you can't use everything as a radiator sufficiently efficient to cool hot chips to safe operating temperature, particularly not if that thing is a thin panel intentionally oriented to capture the sun's rays to convert them to energy. Sure, you can absolutely build a radiator in the shade of the panels (it's the most logical place), but it's going to involve extra mass.

You also want to orient those radiators at 90 degrees to the power panels, so that they don't send 50% of their radiation right back to the power panels.

You can rivet people onto the outside of the ISS to radiate heat, too, but it may be detrimental to the overall system.

It has broken scrolling, very irritating. Scroll to top doesn’t work at all and when I fiddle with the fake windows regular scrolling can’t decide if the fake window or the whole page should scroll.

FaceID is much slower than TouchID, FaceID fails with wet glasses, it fails with a breathing mask. I can’t use the phone with wet fingers or gloves so needing a bare dry finger for TouchID is fine. FaceID annoyingly worse.


The big problem for me is using FaceID in bed. Unless you sleep on your back, the pillow obscures your face.

All you typically need to do is lift your head up so FaceID can get a clear look... but when I'm sleepy, it's annoying.

Ideally, the phone would just have both... somehow... but this seems technically infeasible so I get it


What happened to the blog post? It was moved and now it has disappeared :-(

Sorry, it was published early and we have to wait for some approval checks to clear


No, because Knuth’s test was for Algol 60 and Algol 68 is a very different programming language.


No, it cane from DEC https://en.wikipedia.org/wiki/Numeronym#Numerical_contractio...

It seems unlikely to me that stenography would use this style because they have better ways of abbreviating long agglutinative words.

Before apt, the main user interface for dpkg was dselect, which was written in C++


But doesn't this actually strengthen my point? Debian transitioned from a tool written in a more demanding language to a tool written in a less-demanding one.
