  • I like forums, but maybe I’m part of the problem. I’ve read a forum obsessively for years without registering an account. Even when I have an account, I rarely post/comment. I’ve been reading Lemmy almost daily for over a year before registering an account and don’t reply much even with an account. Decentralization starts with individuals, so I’m going to try to add signal to the fediverse.

    I generally prefer the traditional flat forum UI with oldest first, but that’s mostly a client issue. The problem though is if others are using a different UI the conversation may flow differently (think threaded vs flat forums).

    RE karma, a lot of forums show post counts and like counts next to their forum profile, which is often included in every reply, so in some ways, the likes (karma) was a little more in your face. I think there was less astro turfing due to scope of benefit. What I mean is that while traditional forums were decentralized, so was the account and its reputation, so karma (like/post count) farming was isolated to that specific forum/community and if you were astro turfing, you’d get banned and lose that and could not transsfer that to other forums. Services like reddit effectively make this transferrable between forums. I’m concerned about how this will play out as decentralized platforms grow. It could be worse than reddit. I’ve been trying to come up with ways to handle this, but I can find flaws in every idea I’ve had so far.


  • A friend (works in IT, but asks me about server related things) of a friend (not in tech at all) has an incredibility low traffic niche forum. It was running really slow (on shared hosting) due to bots. The forum software counts unique visitors per 15 mins and it was about 15k/15 mins for over a week. I told him to add Cloudflare. It dropped to about 6k/15 mins. We excitemented turning Cloudflare off/on and it was pretty consistent. So then I put Anubis on a server I have and they pointed the domain to my server. Traffic drops to less than 10/15 mins. I’ve been experimenting with toggling on/off Anubis/Cloudflare for a couple months now with this forum. I have no idea how the bots haven’t scrapped all of the content by now.

    TLDR: in my single isolated test, Cloudflare blocks 60% of crawlers. Anubis blocks presumably all of them.

    Also if anyone active on Lemmy runs a low traffic personal site and doesn’t know how or can’t run Anubis (eg shared hosting), I have plenty of excess resources I can run Anubis for you off one of my servers (in a data center) at no charge (probably should have some language about it not being perpetual, I have the right to terminate without cause for any reason and without notice, no SLA, etc). Be aware that it does mean HTTPS is terminated at my Anubis instance, so I could log/monitor your traffic if I wanted as well, so that’s a risk you should be aware of.

    Since you mentioned an upscaler, I’m assuming you got an old digital (LCD/Plasma/LED) TV that still had a few analog input types (my last couple TVs were lacking on analog inputs). A retro console upscaler probably has better results than your TV, but you can still use an analog switch box before the upscaler. Rather than spend a lot on multiple retro upscalers, spend much less on 1 upscaler and quality analog switch box(es).

    Assuming the old Sony TV is CRT. The answer is still analog switch boxes but without an upscaler.

    Most analog switch boxes can be used for analog audio, most will also be fine for non-optical digital audio. For optical, there are toslink switch boxes, but an audio receiver with multiple optical inputs is what I have.

    EDIT: HDMI mods if they are taking the raw digital output rather than just being internal upscalers are an option, but depending on how authentic you want to be, the analog output circuits also affect the output and so an HDMI mod that bypasses the analog output would lose that.


  • Mead can be made with various spices including tea. There are specific names for these different variations. I don’t know if that’s why OPs’s mead is that color. It could just be the honey.

    I did bee keeping for a few years and the honey harvested at the same time from 2 adjacent hives can look very different in color, but even more so based on the time of year the bees made the honey due to the different plants available. I’ve had honey that was very light in color and some that looked like Guineas when I put it in jars.

    Mass produced honey will just blend honey from hundreds or thousands of hives and even from multiple bee keepers. You get a more of an average, which I suppose is better for consistency/predictability in flavor, which would be important for some types of cooking. The flavors varies due to the different plants the bees collected from just like the color.




  • This may seem pedantic, but mp4 is a container that holds the video and audio streams. The actual video stream can be encoded im various formats (mpeg 2, h264, h265, etc). If you open vlc and look at the codec menu, find the video stream and report back the encoding type it may provide some insight. It could be that there’s a performance regression with a particular decoder or maybe they changed decoding library or any number or things. Sorry it’s a bit vague, but what I’m getting at is if we know the actual video encoding of the file it may help to track down the decoding performance issue.

    If it does turn out to be mpeg2, it could be that something changed about how the video decoding drivers (kernel module) are loaded. Like maybe they stopped including them by default or are no longer being used for some reason.

    If it’s not mpeg 2, then could look in to decoder specific changes between distro versions or hardware support related changes (like maybe a kernel module needs an extra config passed to it to get better performance on 3b), or even decoder library config may be possible to tweak. Sometimes performance optimizations make things worse and the new default configs work better on newer hardware but worse for you.

    In any case, I think knowing the specific video encodings would be helpful. I also just remembered that I had some performance issues on some files due to audio formats if I was having the Pi software decode vs connected to an external AV receiver that could decode the bit streamed audio data.


  • What encoding are the files? Given that it sounds like this is an old set up and maybe old files, some raspberry Pis and I’m pretty sure the 3b was one as I had one, did have support for hardware decoding mpeg 2 (maybe others, I don’t remember), BUT this required purchasing a license for it. I never did, so idk what form the license came in. If it was a file on your SD and you don’t have it on your new installs, that’s my bet. Either that or newer software is more bloated or otherwise performs worse making the experience overall worse. Sometimes on old hardware, older software is the better choice (ignoring security of course).


  • Depending on your comfort level, you may want to do what I’m in the process of doing. I’m still waiting on parts, but this will work for my heating system.

    I have old 2 wire thermostats in a few places I want to replace. I have hot water baseboard heat with multiple heating zones. I couldn’t find an existing solution that worked the way I wanted and was reasonably priced, so I decided to make my own. This only works for single stage systems and for which exhaust fans, circulation pumps, or other components are controlled by the heating system generally and not by a single specific thermostat, which if you have those old mechanical 2 wire thermostats is almost certainty the case. You could do more sophisticated, but I don’t need to.

    All I need is a relay (controlled by HA) to simulate the thermostat turning on/off. I also need some way to tell it when to turn it on/off (such as a temp sensor), again lots of options with HA.

    This can be done in a variety of ways, but I’m using nodemcu boards (they have wifi onboard) and esphome firmware. I’ve used this combination for a number of HA integrations so far. Near my boiler where all of the old thermostats connect will be a nodemcu board with multiple independently controlled relays (for each thermostat to control the individual heating zones).

    The 2 wires that go to my old thermostats will be power supply for separate nodemcu boards, which will be in a 3d printed case along with buttons, display, and (in one room) will also include a temp/humidity sensor since I don’t already have one there. The other locations already have more sophisticated air quality sensors that include temp/humidity, so no need to duplicate, although maybe I will for redundancy.
