  • 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).




  • Jesus, what a bunch of needless “security”

    I disagree with this part. Ticket theft is an actual issue, there are lots of ways to get a copy of someone else’s barcode and either use it before they do or (more likely) sell it to someone else online. TicketMaster’s marketing is talking up the increased security to distract from their true purpose, which is of course to find more ways to take more money from fans. Of course it’s debatable whether the increased security is worth the decreased convenience for ticketholders. That is the inevitable tension when it comes to security, where any increase in security always incurs at least some cost in terms of convenience.

    This is all for personal data mining.

    TicketMaster might be selling user data, but I don’t think that’s their main aim. They want control of the resale market so they can take a cut when tickets are resold. Note how they don’t allow direct transfers between two mobile wallets, they only allow transfers using their app. That’s so they can monitor transfers. If they see someone transferring dozens or hundreds of tickets to many other TicketMaster users then that person is likely reselling and they can clamp down on their account. TicketMaster’s true intent is to force all resales onto their ticket marketplace, because that’s where they get to take a cut of resales.


  • Oh yes, I don’t mean to absolve them of any blame. They treated it as an expensive lesson, which is probably the best way for them to process it.

    Also while TicketMaster is going to sell this as being an “enhanced security” thing, it’s pretty obvious that increased security is only a side benefit for them. Their angle in this is getting more control over the tickets they sell. As long as there are many people who want to go than can physically fit in a venue, there will be a reselling market for event tickets. TicketMaster wants to take a cut of these downstream transactions.

    While the security of rotating barcodes does hinder outright scams, mobile wallets normally allow wallet users to transfer items like tickets to another user if the ticket issuer allows it. TicketMaster does not allow this for their tickets, of course, because it could allow someone to resell tickets while cutting TicketMaster out of the transaction. Currently TM allows transfers using their app, but I’m sure they monitor usage of the feature and clamp down on anyone transferring many tickets. In other words if you try to resell in bulk without using TicketMaster’s own platform (where they get to take a cut), they drop the hammer on you.


  • The reason you can’t use screenshots or printouts is because they’re now using rotating barcodes. Much like the rotating codes in an authenticator app, the number values behind the barcode are changing on some regular cadence. Only the most recent barcode value is considered valid.

    The only other option is to use a mobile wallet, but that prevents me from sending my friends their tickets, since I purchased them all together.

    Some ticket sellers allow you to transfer tickets from one wallet to another wallet, but of course TicketMaster isn’t one of them because they’re fucking TicketMaster. What TicketMaster does allow is transfers from one TicketMaster account to another. Of course then everyone needs to have a TicketMaster account, needs to have the app, etc. It’s either that or leave all the tickets in your app or wallet and go in together. If you tell the door person “I have the tickets for these X people,” they’ll be able to handle that.


  • Yes because the security of barcodes and screenshotted tickets were such a huge problem before.

    I think what you just described is actually a problem. Friends of my parents were visiting somewhere, bought tickets to a show from a reseller, met up with the seller (normal looking guy, no red flags, gave some plausible story why he was selling) and paid cash for printed out tickets with barcodes. Printouts looked legit, dates on the printouts were correct, etc. Went to the doors, tried to scan their tickets, got told that unfortunately they’d just been scammed. The impression they get from the box office worker is that this sort of bad news is something they’ve had to deliver frequently. Anecdotal, but I doubt those friends of my parents were the only ones to get scammed in this way. TicketMaster still sucks as an organization but the extra security of rotating barcodes does serve a legitimate security purpose, just like the rotating security codes generated by an authenticator app.

    Airlines have recently been having problems with stowaways using screenshots of boarding pass barcodes or QR codes too. Such stowaways should get caught before departure by passenger headcounts or boarding ID checks, but clearly there are gaps or breakdowns in these procedures because some of these stowaways are getting caught at the destination. Others may have successfully flown for free. If it keeps happening I bet we’ll see rotating barcodes come to mobile boarding passes too, if that hasn’t already happened.



  • 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.



  • 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.





  • Several years ago I was getting a lot of acid reflux. Went to the doctor, he gave me the “no-fun diet” list with all the foods to avoid because they can cause indigestion. Everything I loved was on that list. Beer. Cheese. Fried foods. Hot peppers. And, of course, coffee. I was highly motivated to achieve some kind of resolution to these stomach problems so I gave up everything on the list except coffee. Lo and behold, the symptoms remained. I switched the roles and gave up only coffee. The stomach symptoms disappeared, to be replaced by the worst fatigue headaches I’ve ever encountered. It took two weeks for the headaches to finally fade, and now I’m a tea drinker for life.

    I drink Earl Grey tea, mostly because I’m forgetful as hell and I need a tea where I can just leave the tea bag in there for as long as it takes me to remember that I made tea. With most other black teas if you don’t yank the bag out at the right time your tea will get bitter as hell. Not Earl Grey, you can forget that shit for half an hour and the Earl don’t mind. You’ll still come back to a cup of tea that’s still perfectly drinkable. When I want to take it to the next level I get some Cream of Earl Grey, the kind with the little blue flower petals in it. Heavenly.




  • I’ve got a Garmin Vivoactive 3 and it works great. Heart rate tracking seems decent, and it will also do pulse oxygen though I usually leave that off because it drains the battery faster. The price is good too, they can be had new for $230 Canadian, so probably sub-$200 US.

    Android app works well often, mostly I just use it as a bridge to get my calories burned data into a calorie tracking app (Chronometer, free version). The calories burned estimate seems to be decently accurate. I’ve been trying to eat 500 calories under the estimated burn rate, and I’ve lost 30 pounds since last November. Not a linear process, there were lots of events and trips where my willpower went right out the window, but those weren’t the watch’s fault!

    Hard cheeses are dense enough that the mold can only grow on the surface. If you cut off the moldy parts and discard them, you’re getting rid of the vast majority of the mold. There will likely be some spores on the rest of the cheese, but not enough to harm you.

    Soft cheeses are much less dense, meaning that the mold can penetrate below the surface more easily. If you can see mold on top then it’s likely throughout the cheese, and thus it’s much less safe to eat.
