  • Doesn’t matter. You still need some condition to trigger price changes. No grocery is going to change the price of bread based on the wheat futures market, because no consumer cares about wheat futures. Maybe they’d change based on their own inventory, but they can’t do that too quickly, or the price will change between the time customer picks up the product and the clerk rings it up.

    There’s a whole population of people who shop in advance - visit web sites, check the store fliers, whatever - to get the best price. If a shelf price doesn’t match their researched price, they’re never going to that store again.

    Aside from gas stations, grocery stores seem to have the most volatile pricing. They’re already making weekly changes on dozens of items, probably based on purchasing algorithms. Maybe that counts as retail “surge” pricing, but it’s not the dynamics that people fear when talking about digital price tags.


  • The actual circumstances where surge pricing would be worth doing are pretty uncommon. Like, what news item would make a manager think “Oh, I should double the price of jeans for the next four hours” or “No one will care if the price of eggs is 50% higher between 7am and 11am”. Price changes longer than that, or less frequent than weekly are just price changes, and digital tags just make it happen faster, more reliably, and with less labor.


  • Depending on the board in your mini-server, you may have enough SATA ports to plug in directly. I have a system similar to what you’re describing (N100 with 4x 2TB HDDs with 1.5TB data): 2 of those drives are set up in RAID1 (mirror), and once a month, I plug in one of the spares, rsync the array to it, and unplug it. Every 3 months or so, I swap the offline drive with an offsite drive. I used to use a USB dock for the offline drive, but I got a 3-bay hot-swap enclosure to make the whole process faster and easier.

    The server shares the array via NFS and SMB, and it is absolutely a NAS for all my other systems.

    If you expect to exceed 2TB data within 2 years, then you’ll need to replace all 4 of those 2TB drives in 2 years. You might, today, get a pair of 4 TB drives and one 2TB, use the 4TB as your main storage, the 2TBs as rotating backups, and wait until you actually outgrow 2TB to upgrade the backups.





  • I see you’re getting lots of advice just to use c/selfhosted as a free consultant. That’s good advice if you’re self-motivated and focused.

    If you want someone to be a coach through the process, to keep you focused and moving, that’s a) a slightly different skillset and b) worth putting in the description. I mention this only because I have a bunch of aspirational projects on my to–do list that have just sat there for literally years because of perfectionism, anxiety, and maybe some undiagnosed ADHD. I’ll also counter by noting that a lot of people, this time of year, buy a gym membership on the theory that spending the money will somehow force them actually to go to the gym, only to find that spent money is not actually a motivator.







  • If you want it to be an actual community service, then you want it to be something that outlives your residence, your tenure as event coordinator, and your interest in being the neighborhood IT guy. It’ll be much easier to transfer control of a VPS to your successor than to give them hardware that also hosts a bunch of your personal services.

    You can start with a very small, nearly free VPS while you recruit users & scale up as (if) anyone bites. Probably even get the HOA to pay for it.



  • This is my problem, too. I’ve gotten so entrained to hoard resources and make gold go up. I explore enough planets to put mines for every resource next to teleporters, then I run around the teleporters collecting resources until the overflow my storage. I’m a little jealous of people who have the creativity and attention to build big, elaborate bases with all of those resources - they look cool, it must feel very rewarding to see them develop, but if it’s not utilitarian, I can’t motivate myself.

    Of course, I’ve got probably 200 hours hoarding resources…

    I got my Pi4 to be a media player - LibreElec or Kodi - for my old, not-smart TV. It plays my library of CDs&DVDs, frontend for OTA TV, and a variety of streaming services. Fanless, so it doesn’t distract from audio, low power, so I don’t mind leaving it on 24/7. You can configure it to listen to a USB IR receiver, but I control mine from phone via web. The actual media library/NAS and tvheaded run on an old desktop in another room.

    My favorite thing is all the sensors you can hook up. Adafruit & Sparkfun have a wide array of sensors with breakout boards for simplicity and well documented python libraries. I started just logging temperature, humidity, then air quality, CO2 to my own database and web page, but eventually expanded to full HomeAssisstant system.
