The windows are so small because Concorde cruised at 60,000 feet. At that altitude the usual oxygen masks won't keep you conscious. The windows are small so that if one ever failed, Concorde could descend fast enough to an altitude w

In principle you've got spatial diversity at both ends - on the ground and in space. I don't mean full duplex - I mean that the same area on the ground can in principle be covered by multiple Starlink satellites simultaneously us

The paper is about delay-based congestion control algorithms such as BBR, Vegas, etc. From their conclusion: "We offer three key conclusions for CCA designers, who should model (or better estimate) non-congestive delays explicitly in

Yes, exactly. And once it's in compression even at higher temperatures it will often be fine if left alone. This is why railway companies impose speed restrictions when it gets hot - they don't want the dynamic load of a passing

It's not so much the materials - modern rail, especially for high speed trains is laid in long continuously welded sections. The track is pre-tensioned so that at cold temperatures as it tries to shrink it is under significant tension

Apparently I'm also ugly, but I'll take consolation in having 81 years more to live. Sadly, that's probably because my age came out as NaN. I'll just take that I'm ageless :)

The problem is your "constant time" operation now spends some time doing work and some time not. When it's not doing work, the CPU can perform work for other processes or threads and this is, at least in principle, measureab

Even if they didn't try to pack in too much detail, I still think many of the redesigned symbols are less obvious than the originals. A square with a circle in it - is that the washer or the dryer? They're both boxes with round

Interdependence can be complicated and assymetric. Russian gas dependency indeed provides a disincentive for Germany to support Ukraine against Russia, but at the same time it emboldened Russia because Putin likely believed the EU was weak

I had the same issue, except it was usually every couple of days they'd need replugging to resync. Only regret from running ethernet recently (yes, it was messy) is that I didn't do it 10 years ago.

Yes, in principle. In practice I found all the TP-Link ethernet-over-power equipment I used to use to me even less reliable than the WiFi I was trying to supplement. It would work fine for a while, then just lose sync, and I'd have t

Any evidence supporting general relativity at these scales is presumably also evidence in favour of dark matter actually being matter, as opposed to gravitational theory needing modification. Seems like we can still learn quite a bit from

I hope autonomous buses are more patient with cyclists than human drivers are. Don't you love it when a bus passes you just before a bus stop, then brakes to a stop right in front of you, forcing you out into traffic to pass. Would o

It will be very interesting to see how they manage queuing across the network of ISLs. The latency benefits can be real, but only if they don't allow queues to build in the satellites themselves. It's not too hard if you run the

If people really don't like them, I'm surprised a little mild civil disobediance campaign hasn't broken out, such as wedging the door open after getting something out. They'd soon get the message.

You are probably correct - I assumed the ballast tanks were part of the end doors, which were later removed, but re-watching, I think I read too much into that part of the video.

As the segments float when they are filled with air (this is how they're floated out for installation), the only reason they won't float back up when installed is that they're covered with a layer of rocks afterwards. Thus I

It's all about sybil attack prevention. They want to limit high rate algorithmic generation of accounts, so they need some verifiable ID that cannot itself be generated at a high rate. They're not using it to verify your identit

The comment about recycling the aramid fibres from bulletproof vests amuses me. Bulletproof vests seem several orders of magnitude rarer around where I live than electric cars. Doesn't really make me want to move to Michigan...

Of course that SIP (not my one) and Paul Francis's PIP were what got merged to become IPv6. The rationale was that 128 bit addresses allowed all the flexibility of address hierarchies from PIP within a fixed length address. With hind
