    I haven't installed one yet, but plan to in my house. I'll probably end up buying an assembly, but they seem pretty spendy for what is really a very cheap BOM.

    I think what you really want is an Energy Recovery Ventilator. It cycles in fresh air and uses an intercooler to limit the heat and humidity loss.

    I would actually expect the math to decode ads-b traffic is substantially less complex than, for example, a TLS connection.

    The max steering angles of the phased arrays are much higher, the diameter is at least 10x what you say. And for the last few years, lasercoms can route traffic inside the constell…

    On the platforms I've worked with, the weight isn't the issue so much as the quantity of expensive and vibe sensitive parts that are unsprung.

    The doubt is supposed to stay with you! You need to make sure there aren't other causes or contributing factors hiding behind 'the obvious'. There have been notorious cases in spac…

    This is correct. If you don't like heights, that's definitely not a reason to skip the tour, but you'll miss out on one piece (that I enjoyed).

    Seconding this! Make sure you get the "special tour". It was an absolute highlight of my trip. If you are interested in power infrasture it's a must see. If you're afraid of height…

    JetBlue is a small rival (JetBlue at ~5% of US traffic, Spirit at ~3%) to the big 4 United/American/Southwest/Delta (each with ~17%). At least on the surface, a larger JetBlue migh…

    This is actually what is thought to partially have caused the damage seen previously. The new trajectory is supposed to just have a single heating pulse instead of two.

    Well, the IRGC folks actually fighting probably don't have a luxurious future in a reformed Iran, so they might not be far off fighting for their lives.

    The phones get larger and the UI gets less information dense every release. More padding, more offsets, more dead space.

    The document describes proof of effectiveness as supported by demonstrating "non inferiority to... a US licensed product". So yes, a (licensed) benchmark, but I see no references t…

    The point is that it's a technical criteria that allows you to exclude American production from Europe. It's just protectionism.

    You say economics instead of emotion, but your last sentence is emotion. If capex is your concern, explain the purpose of canceling an almost-complete farm. If energy breakevens ar…

    In their defense, if "things get bad", they probably lose their job and will be forced to leave. It's hard to put down permanent roots if you can be kicked out in 90 days.

    There have been numerous issues in the past with 'dead' satellites waking back up and activating transmitters again, generally making a mess of the spectrum. Some satellites have p…

    "significant" is doing a lot of work here. spaceX appears to have spent ~$10B on development and infrastructure for Starship so far. NASA has been invoiced for ~50% of their $2.9B …

    So you employed 45 employees to do assembly work but bought each of 2000 parts one at a time so the processing fees were meaningful? Surely if the revenue supports that staffing, y…
