- Comment on Would a cheap, used raspberry pi 3 make for a good test server for following random self hosted tutorials? 2 days ago:
$25 is too much for a used 1gb pi 3. A new pi 5 with 1gb is $45 and way better. But, most ppl start with a vps.
- Comment on Searching for eBook reader solution 2 days ago:
I see, yeah there is something about it in the blurb. How do you like the tablet? Is it responsive? Is it full of Android bloatware? Do you know if it is rootable?
I see there is a 14 inch version that’s about $300 and that starts to get interesting. It’s not “2nd gen” though. And, I had thought of TCL as a lower tier manufacturer with quality issues, but I hadn’t looked into it much.
I like that the tablet has an SD (probably microSD) slot. Don’t like that there’s no headphone jack. There’s plenty of space in those things compared to a phone.

If anyone was wondering: www.tcl.com/us/en/products/…/nxtpaper-11-gen2
11 inch display with 60 hz refresh, but it sounds like regular lcd rather than e-ink? It has an 8000mah battery that it says can run the tablet through a full day, so that’s nothing like an epaper tablet.
Anyway, I’ve been using Librera FD for reading epubs on Android. Its blurb mentions annotations but I’ve never tried that feature.
I have an Inkplate 10 e-paper tablet but haven’t been using it.

At minimum there should be a good description of what the video is about, with no clickbait.
- Comment on Could there be additional forces at super low energies? Could a new fundamental force be discovered anytime soon? + other questions relating to forces 4 days ago:
Currently known forces splitting at low energies, and hidden 5th force: nobody knows. Physics is an observational science and right now there aren’t any observations that require such observations, but never say never.
Star wars force: come on, it’s fiction.
Gravity incompatible with QM: basically, quantum field theories are developed by starting with classical field theories (say electromagnetism) and doing some mathematical transformations called “canonical quantization” and “second quantization” (these have wikipedia articles). In the 1920s through mid-1940s this worked well for electromagnetism, and made good predictions except it broke down at very small scales, giving “infinity” as the answer to calculations that should have been finite. In the late 1940s a scheme called renormalization was developed, that allowed cancelling out the infinities and getting very precise answers. That was called quantum electrodynamics (QED). Later this was extended to the strong and weak nuclear forces, giving the standard model (SM). That was harder, but same basic idea.
The trouble with gravity is that when you perform quantization and then renormalization, the infinities still don’t go away. That’s what the incompatibility means. There are a lot of proposals like string theory to quantize gravity, but it’s all very speculative.
As for detecting gravity waves but not gravitons, it’s similar to the situation with visible light. As far back as the 1700s(?) it was possible to combine light beams and see interference patterns, thus confirming the existence of light waves. Light “particles” (photons) are much harder to detect and I think this was first done convincingly by Einstein’s explanation of Brownian motion around 1900 (before relativity).
Disclaimer: I’m no expert and I haven’t made any progress in understanding this stuff beyond the handwaving level that you see above.

Web search shows max CPU power for that unit is 65W. I was thinking of something more power hungry.

- Comment on Making setups resilient to outages 2 weeks ago:
Maybe you could describe what you mean by self-hosted and resilient. If you mean stuff running on a box in your house connected through a home ISP, then the home internet connection is an obvious point of failure that makes your box’s internet connection way less reliable than AWS despite the occasional AWS probs. On the other hand, if you are only trying to use the box from inside your house over a LAN, then it’s ok if the internet goes out.
You do need backup power. You can possibly have backup internet through a mobile phone or the like.
Next thing after that is redundant servers with failover and all that. I think once you’re there and not doing an academic-style exercise, you want to host your stuff in actual data centers, preferably geo separated ones with anycast. And for that you start needing enough infrastructure like routeable IP blocks that you’re not really self hosting any more.
A less hardcore approach would be use something like haproxy, maybe multiple of them on round robin DNS, to shuffle traffic between servers in case of outages of individual ones. This again gets out of self hosting territory though, I would say.
Finally, at the end of the day, you need humans (that probably means yourself) available 24/7 to handle when something inevitably breaks. There have been various products like Heroku that try to encapsulate service applications so they can reliably restart automatically, but stuff still goes wrong.
Every small but growing web site has to face these issues and it’s not that easy for one person. I think the type of person who considers running self-hosted services that way, has already done it at work and gotten woken up by PagerDuty in the middle of the night so they know what it’s about, and are gluttons for punishment.
I don’t attempt anything like this with my own stuff. If it goes down, I sometimes get around to fixing it whenever, but not always. I do try to keep the software stable though. Avoid the latest shiny.
- Comment on Can we have a healthy life only with fruits or fruits and plants combined alone, and if not why? 2 weeks ago:
Being vegan takes a bit of nutritional awareness but it’s not that difficult. You might want some vitamin supplements as people have said. Note that fruit isn’t that much different from candy in terms of the sugar hit. I’m not vegan myself in terms of intentionally sticking to such a diet, but often my eating patterns end up going that way anyway, and it works out ok, at least for a while.
- Comment on Recommendations for an all-SSD home server? 2 weeks ago:
A high-cpu small machine will have noisy fans, there’s no avoiding that. The fans have to be of small diameter so they will spin at high RPM. Maybe you can say what you’re actually trying to run, and make things easier for us.
I gave up on this approach a long time ago and it’s felt liberating. My main personal computer is a laptop and for a while I had a Raspberry Pi 400 running some server-like things. All my bigger computational stuff is remote. So the software is self-hosted but not the hardware. IDK if that counts as self-hosting around here. But it’s much more reliable that way, with the boxes in multiple countries for geo separation.
- Comment on Your old android phone is begging to be a cheap home server! 2 weeks ago:
I got my current phone in 2023 and the one before that in 2017. The 2017 one was my first android phone. The previous couple were Maemo, which tbh would be better for servers.

- Comment on Your old android phone is begging to be a cheap home server! 2 weeks ago:
Well my old phone is micro USB for now. Someday my new phone will become an old phone and I can revisit the scheme. It has USB-C.
- Comment on Your old android phone is begging to be a cheap home server! 2 weeks ago:
Um no, phones are terrible for that. My old phone in particular is a PITA to even keep powered, because of its flaky micro USB connector. Then we get to the lack of Ethernet, the difficulty of remote reboot, and the Android OS even with termux. It’s .much better to scrounge an old PC or raspy pi or the like.
- Comment on New battery life record: This CPU makes the best known business laptop more efficient 2 weeks ago:
Web browsing is monstrously demanding of CPU so if the laptop can do it, it’s not so slow. A 20 year old laptop can email or word process perfectly well today, but it can’t browse. The modern web is just too bloated.
- Comment on 3 weeks ago:
I had an Acer as a work laptop some years back. It was fine, though I didn’t use it that heavily, so maybe issues would have come up if I did. Also, maybe there are worse now.
For personal use I’ve generally bought Thinkpads and pounded the crap out of them. I’m currently thinking of getting a Lenovo Yoga if they go on special Black Friday again, but I have trepidations.

- Comment on When "AI" content becomes indistinguishable from human-made content, is there, philosophically speaking, any meaningful differences between the two? 3 weeks ago:
It’s up to you. There’s a traditional wooden drinking cup called a kuksa that is popular with outdoors types. It’s carved from a solid block of wood. You can buy them, but it’s more “bushcrafty” if you make one yourself. Further, you’re supposed to use only hand tools, no power tools. OTOH, one that you order online was probably milled by a machine. It’s hard to tell them apart though.
Is there a philosophical difference? Up to you.

I don’t really have any of those. My stuff goes down and I later get around to restarting it. I’m a wimp in not self hosting more important stuff like email. But my media files are on a local disk rather than a server.
