  • It’s likely CentOS 7.9, which was released in Nov. 2020 and shipped with kernel version 3.10.0-1160. It’s not completely ridiculous for a one year old POS systems to have a four year old OS. Design for those systems probably started a few years ago, when CentOS 7.9 was relatively recent. For an embedded system the bias would have been toward an established and mature OS, and CentOS 8.x was likely considered “too new” at the time they were speccing these systems. Remotely upgrading between major releases would not be advisable in an embedded system. The RHEL/CentOS in-place upgrade story is… not great. There was zero support for in-place upgrade until RHEL/CentOS 7, and it’s still considered “at your own risk” (source).




  • I’m sure there would be a way to do this with Debian, but I have to confess I don’t know it. I have successfully done this in the past with Clover Bootloader. You have to enable an NVMe driver, but once that’s done you should see an option to boot from your NVMe device. After you’ve booted from it once, Clover should remember and boot from that device automatically going forward. I used this method for years in a home theatre PC with an old motherboard and an NVMe drive on a PCIe adapter.


  • Just to make sure I’m understanding what I’m seeing, the plane gets hit at 1:03. The regular bursts of light from the start of the video to 1:01 are aircraft flares? Possibly parachute flares? At least some Russian aircraft apparently have parachute flares. At 0:23 you can see smaller flares being shot out to the side of the main flare. I think many aircraft flares fire in this sort of pattern because it makes the flares better mimic the shape of an airplane. Bonus points for looking really cool:

  • People here seem partial to Jellyfin

    I recently switched to Jellyfin and I’ve been pretty impressed with it. Previously I was using some DLNA server software (not Plex) with my TV’s built-in DLNA client. That worked well for several years but I started having problems with new media items not appearing on the TV, so I decided to try some alternatives. Jellyfin was the first one I tried, and it’s working so well that I haven’t felt compelled to search any further.

    the internet seems to feel it doesn’t work smoothly with xbox (buggy app/integration).

    Why not try it and see how it works for you? Jellyfin is free and open source, so all it would cost you is a little time.

    I have a TCL tv with (with google smart TV software)

    Can you install apps from Google Play on this TV? If so, there’s a Jellyfin app for Google TVs. I can’t say how well the Google TV Jellyfin app works as I have an LG TV myself, so currently I’m using the Jellyfin LG TV app.

    If you can’t install apps on that TV, does it have a DLNA client built in? Many TVs do, and that’s how I streamed media to my TV for years. On my LG TV the DLNA server shows up as another source when I press the button to bring up the list of inputs. The custom app is definitely a lot more feature-rich, but a DLNA client can be quite functional and Jellyfin can be configured to work as a DLNA server.




  • This shit has been going on since the 80s. It’s mostly bullshit instigated by US lumber companies. Available softwood lumber in the US is mainly on privately owned land, and the owners of that land want the price of lumber to be as high as possible so they can make more money. The softwood lumber companies in the US are effectively acting as an oligopoly, and they lobby US politicians for legislation in their interests.

    Softwood lumber in Canada is mainly on public land, called “crown land” here in Canada. A lumber oligopoly isn’t possible in Canada because the government would never sell all of that land to a handful of lumber companies. Instead lumber producers in Canada are charged a fee for the logs they cut, that fee is set by the Canadian government, and it is less per log than what US lumber producers want to charge.

    Instead of competing on price, US lumber companies lobby congress to impose softwood lumber tariffs for the umpteenth time. When the US lumber companies don’t need to compete with Canadian lumber, they can jack up their prices. When they do that the only people who benefit are the US lumber companies and the politicians they’ve lobbied. Americans pay more for lumber, Canadian lumber companies and their workers suffer.


  • After reading the article, I’m confused about how it works. Guinea worms are parasites that you get infected with from bad water sources. Unless you eradicate the source (e.g. the worms themselves), can you really say that you’ve eradicated the disease?

    Many diseases can likely never be eradicated because they have a natural reservoir, some wild population of animal species in which the disease normally propagates. A natural reservoir will keep the disease in circulation and reinfection of humans can occur from contact with species in the natural reservoir. Ebola virus is like that, it keeps popping up now and then because it has a natural reservoir (believed to be fruit bats).

    Guinea worms isn’t like that, which is part of why it’s a strong candidate for eradication. Its reproductive cycle has a step that primarily goes through people or dogs, neither of which would be considered a natural reservoir:

    Guinea worm reproductive cycle

    As such, if we reach a state where there are no infected people or dogs then guinea worm could go extinct. There would be larvae left in the wild at that point, but as long as those larvae don’t infect a suitable host then they never become worms. No new worms means no new larvae, and larvae have a fairly short lifespan so we would only need to maintain that situation for maybe a few years before we could confidently say that guinea worm has been eradicated (i.e. any remaining larvae must be dead by that point).



  • How did this happen? Isn’t there usually a flight attendant standing right there as you board the plane?

    Yes, but the 777 has two aisles. Here’s the Air Canada seat map. The flight attendant greeting passengers would be by the first aisle, directing passengers down the correct aisle for their seat. This passenger might have been directed to the second aisle, and rather than turning down the aisle they went straight across to opposite exit door. Or they might have used one of the other doors. The 777 has 10 full-sized doors, 5 on each side of the plane. Two of those doors open onto the wings, one of those would have been used for boarding, maybe two if first-class passengers get a separate air bridge, but that still leaves 6 or 7 doors where there isn’t likely to be a flight attendant to notice a passenger doing something stupid.
