I'm just some idiot on the internet, but please, put a disclaimer of some sort on this. Polymer fume fever is shitty for people and absolutely hideously lethal for birds. I dunno what the LC50 is for birds, but anecdotally, a bird anywhere in the same building has a nonzero chance of dying. Birds in the same room will die. God knows what all those horrible fluorinated fumes will do to people over the long term, but they make you really sick in the short term.
Trolling can be funny, but not when it's encouraging people to do actively hazardous stuff.
Z-wave LR has no repeaters, it's a star topology. Regular old z-wave is a mesh, z-wave LR is not.
I spent several weeks evaluating options and really wanted to use LoRa for controlling some stuff in a detached machine shop, but I just couldn't find reasonably priced sensors, switches, and gateways (or access points or whatever you call them in LoRa parlance). I seem to recall that one of the major integrations was cloud-polling only which was a huge no-go (same reason I didn't buy in heavily into Yolink, I require 100% local control).
Do you use LoRa? I'd love to hear what you use (brands and vendors to buy stuff from) if so. I try to have at least two different technologies controlling an area. That way, my zwave-js-ui pod occasionally shitting the bed won't completely break an area.
I'm deeply confused. I have a shitload of Zooz stuff that supports Long Range. Does the whole star topology and everything. Is this some sort of new development? Or did the author miss the long range stuff that's been available for a year now?
EDIT: many commentors over on Ars are also confused.
raidz2 is analogous to RAID 6. It's just the ZFS term for double parity redundancy.
I dunno if you would want to run raidz2 with disks this large. The resilver times would be absolutely bazonkers, I think. I have 24 TB drives in my server and run mirrored vdevs because the chances of one of those drives failing during a raidz2 resilver is just too high. I can't imagine what it'd be like with 30 TB disks.
I know this is a shitpost, but treads are not durable compared to good ol' tires. I've heard that setups like this require frequent maintenance. They're certainly more capable of handling certain kinds of terrain, but tires last longer and are simple to replace.
Hey there! I can relate a lot to what you're saying here. I've often felt trapped in a bad place because all of the alternatives seem worse. I had a fairly traumatic upbringing (some emotional abuse, a little bit of physical and sexual abuse, lots of emotional neglect), and I also suffered from a fear that the people around me would mess with me and invade my privacy.
For me, the need for privacy came from a place of deep self-loathing fueled by a shitton of criticism from my dad (why can't you do anything right/think the right things/just focus on something). I didn't want others to see who I really was, so I went to extreme lengths to hide it from the world. Everything was locked, and I used to write my thoughts down in an intentionally opaque way to try to mask what I really felt.
I dunno if that matches your lived experience at all, but one of the consequences of all this was that I did this thing called catastrophizing. I'd become totally crippled and stuck and lost because I'd only see the worst possible outcome in every decision I might make. It's very common for people who have suffered emotional abuse (especially for those who have their judgement, sanity, or morality criticized by their parents). I could absolutely be off base here, but like, I started feeling those feelings of doom and danger as I was reading your comment. I am absolutely not trying to minimize your situation. Catastrophizing is a horrible thing to battle with, and it takes actual traumatic catastrophies before you begin to catastrophize.
w.r.t. home invasions and safety, it might be good to reevaluate that. Is it really so dangerous that you would need to defend yourself? Like, maybe that's the case! I grew up in a pretty safe place, so I lack the proper context to understand that fear. I do know that violent crime is very uncommon. Your situation may seem hopeless and you may feel trapped. I've felt that way. Just know that while some choices have risks and may feel dangerous, things don't always go that way. You deserve to feel safe and secure.
it's trivial to break that approach by obfuscating strings. You can do things like using base64 encoded strings in the source code, building strings from smaller component parts, or using rot13 on, say, the host component of a URI. That last one could be pretty interesting if you, as a threat actor, owned both permutations. The hostname (minus TLD) in the source code could be the nice, human readable version (www.happysite.org) that appears to be something legit. Then, when you rot13 it to www.uncclfvgr.org, traffic is sent to the evil site doing scary things. People can be far more tricksy than that. There's also the whole issue around whether or not the binaries you're running actually match the code in the repo. The xz kerfuffle showed how much can be hidden that way.
EDIT: I should make it clear that I don't use Deepin or the DE it provides because I only use WMs with no desktop, so the distro and DE are of no interest to me. I don't know if it's a security hazard or not, I have no horse in this fight.
Also Nordic noir books fucking rock, I love me some good Nordic noir.
Does runit have the equivalent of systemctl --user
for managing per-user daemons like pipewire? I had some issues with pipewire recently and being able to journalctl --user -u pipewire
and systemctl --user restart pipewire
was a total godsend for me.
Damn, that's crazy to hear! Zooz stuff has been the bedrock upon which I've built all my automation. Like, I have dozens of ZEN04 LR plugs all over my house. What specific Zooz stuff has been unreliable for you? I've only used the ZEN04 LR, ZEN14 LR, and ZEN15 LR plugs so maybe it's just not anything I've ever touched.
Z-wave LR isn't a mesh, and I'd highly recommend it. I have some very chatty smart plugs (I use them to share load on a breaker, so I need power usage updates quickly or the breaker will pop) and they've done a great job on LR.
I avoid anything using WiFi unless it's running open source software. I don't want to manage an IOT VLAN, and there's just no reason my sensors and plugs need to understand IPv4. I just want things to be reliable and self-contained.
Like, I am a very choosy and grumpy person and I get immediately annoyed if I have any sort of connectivity issues. I've been using two Ruckus R750 APs in my 2400ft² (220m²) house with properly set minimum RSSIs, xmit power, and channel usage. IOT stuff owns 2.4 on its own channel as you've said. It's wonderfully reliable and fast! My BLE proxies have had 100% availability (outside of power outages, since only my central rack has battery backup). So is my single 800 series Z-wave LR radio that runs off of PoE and is wired in just like any other AP.
I absolutely ditched zigbee for anything other than sensors though. I just couldn't count on it.
I'm pretty staunchly atheist. My mom took me to a Unitarian Universalist church for a year or so when I was a kid, and that's the closest I've ever come to church or religion. I mostly went for the hot chocolate because god damn, church hot chocolate just hits different. I grew up in a town in Utah that was 95% Mormon, which was pretty weird in retrospect. I thankfully wasn't bullied or excluded for my lack of beliefs, but I did have to suffer through a few conversion attempts. My exmo partner likes to make fun of all the ridiculously incorrect things I've absorbed via cultural osmosis.
I do try to give myself some spiritual time. That usually entails looking at the mountains here and thinking the existential thoughts I normally don't give myself time to think about. If I need to do that while I'm feeling sad or mopey, I'll make some herbal tea and sip it while I'm chilling. I have a really strong aversion to many other forms of spiritualism (like crystals and some forms of meditation) due to some childhood trauma. I haven't worked on that trauma because my approach seems to work well enough for me. I only experience existential dread when I fail to take good emotional care of myself.
ngl, I'd think that someone with the word "water" tattooed on them in a sharpie style like that is cool. It just has a vibe I like.
Yeah, the lifespan and ability to leave a flywheel "discharged" makes me wish I could have one for my homelab (as unrealistic as that might be). I have a solar generator as a battery backup, but it's not a true UPS with a fast transfer switch (I needed at least 3kWh of capacity for long power outages, my max draw is like 600 watts before I finish load shedding). Most of my servers can tolerate the brief voltage sag, but my R640 chokes and dies. My battery is hooked up to one of my PDUs, and I'd love to have a flywheel hooked up to the other PDU. The battery would be fully transitioned by the time the flywheel was discharged.
On the point of safety, I have a question. I feel like it's probably easier to prove that a flywheel system is deenergized, but there is the very slight risk of confinement loss. With a chemistry like Lithium Iron Phosphate that can't sustain a flame and doesn't produce flammable gasses, do you feel that batteries might begin to approach the safety of flywheels? It sounds like you have actual experience with flywheel systems, so I'm quite curious.
EDIT: holy shit, someone is actually selling a 300 KVA flywheel system on eBay for $30,000. I wonder who the hell would buy something like that used.
EDIT: I said "very slight risk" of confinement loss, and I should probably correct myself. The risk is ridiculously, stupidly small for a system like I linked above. Maybe the bigger systems that get buried and have concrete poured on them are riskier, but I don't know if people even do that anymore for datacenters.
Full disclosure, I haven't watched the video, I'm just going off of the other comments. Mechanical energy storage is definitely already a thing. Flywheels are the past, present, and future of energy storage in certain niches. My dad was a PM for IBM for many years and told me all about installing them while building out datacenters in the 90s. They're great for powering large loads while a generator spins up. They're, uh, not really that great for multi-day storage. You're going to lose energy no matter what. Magnetic bearings won't help this, they still have something analogous to friction.
Anything other than batteries or pumped hydro is probably a fool's errand when it comes to grid-level storage. You're not going to make a crane big enough to compete with millions of gallons of water pumped up a hill. You're not going to be able to make a flywheel spin fast enough to compete with millions of gallons of water pumped up a hill. Do not try to compete with the water using your giant spinning death wheel or big dumb crane. Batteries get a pass because they're dense as fuck and very simple to deploy.
Brainrot.
Yep, I put hundreds of hours into Red Alert 2 as a youngun. I would absolutely play the shit out of a remake, provided a map maker was furnished or created by the community. I fucking loved custom RA2 maps.
I feel like I saw people saying this back in 2007 (with different terminology, ofc). Kids just like in-jokes and being ironic. It's not ruining the Internet, big business is what's ruining the Internet.
