  • For a quick and dirty clean room run the shower really hot for a few minutes to make a bunch of steam and then wait for the humidity to naturally equalize, boom you got a few minutes to do your swap job.

    I’ve never heard of this… what’s the idea behind it? That you get the RH near 100%, and any dust particles will be a nucleation point for water to condense on, causing them to literally rain out of the air?





  • I do find it interesting/funny that Google felt the need to actually provide this, as a sort of acknowledgement that their main search “results” page is so full of random info boxes and generated content that people can’t find actual links anymore.

    Personally, and In principle at least, this makes sense. About half of my web searches are looking for a quick answer to a question (what’s the per pound cook time for a frozen turkey?), so having that answer highlighted and summarized alongside the source is very useful. It’s actually the minority of the time that what I really want is a link to an external resource.

    The effectiveness of that implementation and the accuracy of the summarized info is a whole other topic…














  • That’s asinine. It’s like saying “If brakes really mattered, a cop would check your brakes before letting you drive to work in the morning”. Brakes are pretty damn important, but very few places (in the US at least) have any mechanism for ensuring yours are in working order even periodically.

    Proper risk mitigation takes into account (at minimum) the likelihood of an event occuring, the severity of the event occurring, your willingness to tolerate a failure, and the cost associated with implementing corrections.

    Airlines have an EXTREMELY low tolerance for any kind of risk that could conceivably lead to a catastrophic failure, so the fact that you’re allowed to have a device, despite potential safety concerns, comes from a combination of a few factors:

    1. The chances of some kind of major interference with flight ops happening are demonstrably pretty low
    2. People would likely push back quite hard on not being able to use electronic devices for entertainment on a flight.
    3. Most people comply with the request.
    4. Related to 3, there is little reason for airlines to change the rule, since cell operation is next to impossible in flight anyways, and wifi/bluetooth are not in the frequency range of concern.

  • The real issue is that airplane mode should really only affect cell signals now and leave WiFi alone since planes have WiFi now and a lot of applications share between devices with WiFi, and leave Bluetooth and NFC alone since they’re short range and low power and unlikely to cause issues.

    I’m not sure how common it is, but my S22+ will remember if I turn bluetooth or wifi on while in airplane mode, and leave them on in the future. That’s especially nice since I use a CGM that pairs to my phone via bluetooth, so I don’t have to worry about accidentally losing that connection.

    Spot on about there not being any point in having cellular service enabled. You’re 6 miles up and traveling a mile every few seconds, so you might as well just shut that radio off and save a bit of battery power.


  • You have a point about how silly it is to scrimp on ethernet ports in new construction/remodels–wifi with a wired backhaul is unquestionably preferable to pure mesh.

    But to say “wifi has nothing other than mobility” is purely asinine. It’s like saying that planes offer nothing over cars except the ability to travel faster–yeah… that’s kinda the point! Compared to the number of networked devices in the average home, there are very few current or near-future devices that could leverage even a gigabit connection fully, let alone justify a dedicated wired connection.

    Streaming video needs a few 10s of Mbits tops, security cams are similar, streaming audio needs a fraction of that, your smart home devices & hubs are negligible, mobile phones and tablets downloading 100MB apps barely even blink at current wifi speeds. Even the average WFH-er is going to saturate their company’s VPN before their wifi connection struggle.

    Is an ethernet connection technically better in some of those cases? Sure, but the vast majority of people would notice no functional difference aside from having to plug in a second cable.
