MoCA is honestly really great. I've been running 4 MoCA nodes (2.0 and 2.5) in my house for 10 years now, over pretty shitty RG58 cabling and a bunch of splitters, quite long runs too, along with 1 gig DOCSIS 3.1 modem sharing the same cabling, and it has been absolutely bulletproof and reliable (especially compared to the powerline ethernet I was using before, which was absolutely terrible). Plenty of bandwidth for full duplex 1 gig - really the only downside compared to 1 gig ethernet is a few extra ms of latency.

Running ethernet cables everywhere would be very expensive in my situation, and while I considered it a few times to get more bandwidth between my main computer and the NAS which sits in my homelab in the basement, I still find it hard to justify the cost. If I were to pull the trigger now, I think I would go with fiber (or maybe both) - but I would have to replace so much stuff to get up to 10 gigs, all my homelab equipment is 1 gig only, server nics, NAS nics, switches, etc.. it would not be cheap, beyond even just the cost of running the cables. So I am just sitting back and waiting to see how the technology evolves for now.

What kind of battery did you put in ? A standard alkaline battery has different voltage discharge curve compared to the recommended rechargeable NiMH batteries (example)

You can't really measure the capacity of a battery directly, all you can measure externally is the voltage, so the logic has to make some assumptions about the type of battery being used when calculating percentage. Since they recommend the LADDA rechargeable batteries, which are NiMH, they probably set the 100% threshold lower - perhaps as low as 1.2V, so as long as whatever battery you are using is above this voltage, it will show up as 100% - it might take longer for an Alkaline battery compared to NiMH rechargeable, but later you might have the opposite problem, when the reported percentage will start dropping faster for Alkaline vs NiMH, due to the different discharge curve characteristics.

More sophisticated devices can sometimes have a learning function, where they observe the voltage curve over a full discharge cycle of a battery, and then adjust the % reporting to more closely match, but since every battery can be different, this is still not always accurate. The discharge curve can be affected by temperature as well, further complicating the issue.

Since these sensors are supposed to last up to 15 months on single charge, and it actually wouldn't be too unusual for a device like this to report 100% battery for up to the first 1/3 of its battery usable life (especially if using Alkaline batteries), 3 months is probably still within reason. There is often some intentional padding as well by manufacturers, as they don't want customers to see big drop in battery percentage early on, as this might cause people to make ultimately incorrect predictions about total battery life, and complain or return the product.

Pioneers were basically modeled after Scouts, just replacing the religious aspects with political ideology. Usually Pioneers were only for ages up to 14 however. After Pioneers, you were expected to join the Young Communist organization (DISZ and later KISZ in Hungary) which was for ages 14-26.

Like the other Jucika camp comic, this one also more likely references the youth labor camps usually run by DISZ/KISZ.

The "youth camp" back in the period these were drawn likely refers to a youth labor camp (rather than a recreation camp) These were a common thing during socialism - basically high school and college students were "volunteered" to help with seasonal labor (often crop harvesting) when school was out, and sometimes with large construction projects, irrigation/drainage, etc. It was generally unpaid and more or less mandatory work, but also an opportunity to live in a camp with other young people for the summer and socialize, so most people remember them quite fondly.

Lost of photos here from that period, as an example

Have been using Linux since Slackware in the early 90s, both for work and at home - been through a lot of distros since then.

Currently use Debian on my servers and VMs, and CachyOS (with KDE Plasma) on my main desktop. I like the bleeding edge of Arch for my desktop, and find CachyOS to be a very sensible plug and play way to get into Arch (I tried to run Arch before, and also EndeavourOS, although that was a while back and not the smoothest experience for me - things might be more mature now, but CachyOS was the one that finally reached the point for me that allowed a full switch from Windows on the desktop to Linux)

Most of my servers run virtualized on Proxmox, which itself is Debian based though. I also run pfSense as my firewall/router which is FreeBSD based.

Think of how shitty and scam filled the early internet was. Did we abandon it because of how shitty it was at first, or did we develop it and tweak it to it's full potential?

I have been on the internet since 1992, and the internet today is by far the shittiest and most scam infested it has ever been in my time (and I doubt it was worse in the 80s)

Few things make me more depressed than thinking about the evolution of the internet, from where it started to where it is today.

I don't doubt AI will follow a similar path, except somehow it is already starting in a much worse place than the internet ever did, and the downside potential is far greater and terrifying.

Other countries took photos of the Apollo landing sites as well, including China.

The best ones so far were taken by the Indian Chandrayaan orbiters.

Really shows how deep this conspiracy goes ! :)
