  • Average spending is not a good metric for addictive behaviors - spending/consumption tends to be extremely concentrated in a small fraction. My go-to example for this is alcohol where, in the US, 10 drinks/week is the population average, but also enough to get you into the “top 10%” or “heavy drinker” bin, where the average consumption of that bin is 74 drinks/week. In both alcohol and gacha, a huge fraction of the population don’t pay anything.

    I mean, even if the article’s $30/month average spend is entirely within their 20% “problem” spenders, it would only be $150, but it’s a little easier (for me) to see where $150/month gacha habit could be a problem for young people already on the financial edge. Not the fundamental problem that skyrocketing rent and stagnant wages are, but more in the last-straw sense.

    Wonder if there’s an opportunity there. Some way to archive one’s self-hosted, public-facing content, either as a static VM or, like archive.org, just the static content of URLs. I’m imagining a service one’s heirs could contract to crawl the site, save it all somewhere, and take care of permanent maintenance, renewing domains, etc. Ought to be cheap enough to maintain the content; presumably low traffic in most cases. Set up an endowment-type fee structure to pay for perpetual domain reg.

    At least my descendants will own all my comments and posts.

    If you self-host, how much of that content disappear when your descendants shut down your instance?

    I used to host a bunch of academic data, but when I stopped working, there was no institutional support. Turned off the server and it all went away (still Wayback Machine archives). I mean, I don’t really care whether my social media presence outlives me, the experience just made me aware that personal pet projects are pretty sensitive to that person.



  • Back in the day, I set up a little cluster to run compute jobs. Configured some spare boxes to netboot off the head-node, figured out PBS (dunno what the trendy scheduler is these days), etc. Worked well enough for my use case - a bunch of individually light simulations with a wide array of starting conditions - and I didn’t even have to have HDs for every system.

    These days, with some smart switches, you could probably work up a system to power nodes on/off based on the scheduler demand.

    If you’re already running Pihole, I’d look at other things to do with the Pi.

    https://www.adafruit.com/ has a bunch of sensors you can plug into the Pi, python libraries to make them work, and pretty good documentation/examples to get started. If you know a little python, it’s pretty easy to set up a simple web server just to poll those sensors and report their current values. Only slightly more complicated to set up cron jobs to log data to a database and a web page to make graphs.

    It’s pretty straightforward to put https://www.home-assistant.io/ in a docker on a Pi. If you have your own local sensors, it will keep track of them, but it can also track data from external sources, like weather & air quality. There a bunch of inexpensive smart plugs ($20-ish) that will let you turn stuff on/off on a schedule or in response to sensor data.

    IMO, Pi isn’t great for transport-intensive services like radarr or jellyfin, but, with a Usb HD/SSD might be an option.


  • That’s my point: fusion is just another heat source for making steam, and with these experimental reactors, they can’t be sure how much or for how long they will generate heat. Probably not even sure what a good geometry for transferring energy from the reaction mass to the water. You can’t build a turbine for a system that’s only going to run 20 minutes every three years, and you can’t replace that turbine just because the next test will have ten times the output.

    I mean, you could, but it would be stupid.



  • I’ve always understood 2 as 2 physically different media - i.e., copies in different folders or partitions of the same disk is not enough to protect against failure of that disk, but a copy on a different disk does. Ideally 2 physically different systems, so failure/fire in the primary system won’t corrupt/damage the backup.

    Used to be that HDDs were expensive and using them as backup media would have been economically crazy, so most systems evolved backup media to be slower and cheaper. The main thing is that having /home/user/critical, /home/user/critical-backup, and /home/user/critical-backup2 satisfies 3 copies, but not 2 media.


  • 3: RAID-1 pair + manual periodic sync to an external HD, roughly monthly. Databases synced to cloud.

    2: external HD is unplugged when not syncing

    1: External HD is a rotating pair, swapped in a bank box, roughly quarterly. Bank box costs $45/year.

    If the RAID crashes, I lose at most a month. If the house burns down, I lose at most 3 months. Ransomware, unless it’s really stealthy, I lose 3 months. If I had ongoing development projects, a month (or 3) would be a lot to lose, and I’d probably switch to weekly syncs and monthly swaps, but for what I actually do - media files, financial and smart-home data, 3 months would not be impossible to recreate.

    All of this works because my system is small enough to fit on one HDD. A 3-2-1 system for tens of TB starts to look a lot like an enterprise system.

    It’s not like Democratic administrations gave us the voting rights act, gay marriage, interracial marriage, and abortion. Medicare & Medicaid. Ended Don’t-Ask-Don’t-Tell. The ACA may not be very close to universal healthcare, but it is a huge improvement on what we had, and it decreased the uninsured population by 15-20M.

    There’s a lot more to want from a progressive party, but they have, slowly, made things better. Sometimes, the wing nuts claw those improvements back, and “Ratchet Effect,” “Both Sides,” etc are great propaganda for cowing opposition to the wing nuts.
