  • Want to see shit really hit the fan? Imagine if Taiwan applied for NATO membership. They are already recognized by most countries as an independent entity and I assume are aligned with many Western goals since they conduct joint military exercises with the US, but China would go crazy over attempts at NATO membership.

    Makes me wonder if there are are any rules to prevent acceptance if a country is attacked because of asking to join? Like I know Ukraine can’t join right now because they’re already at war (despite whatever Russia wants to call it), but I think Taiwan is not officially at war with anyone.


  • We’ve been seeing these electronic tags on sale items at Walmart for the past few years. It’s been a few months since the last time we were in the store, but last weekend we noticed ALL items now had small two-color OLED price tags on them. I don’t know if that means we’re just lucky enough to be one of the first to get the new tech, or that the chain had already started rolling them out well before the article, but they’re definitely out there. I’d actually love to get ahold of some just to play with them, although seeing the prices of OLEDs on ebay makes me wonder how any store is saving money by using them.


  • There’s also the issue of very little (if any) used EVs on the market, and in an affordable range. Most people are looking for a reliable used car for around $1000-$2000 US, and the cheapest EV I have seen is around $7500. And there’s always the question of what condition the batteries are in – if you had to replace all the batteries in a used EV then you easily doubled the cost of it. Fortunately it seems like Tesla is the only manufacturer asinine enough to seal their batteries, other manufactures allow replacement of individual cells which will really help in the used market.



  • I’ve never used TrueNAS, but my experience with ZFS is that it could care less what order the drives are detected by the operating system. You could always shut down the machine, swap two drives around, boot back up, and see if the pool comes back online. If it fails, shut it back down and put the drives in their original locations.

    If you are moving your data to new (larger) drives, before anything else you should take the opportunity to play with the new drives and find the ZFS settings that work well. I think recordsize is autodetected these days, but maybe for your use things like dedup, atime, and relatime can be turned off, and do you need xattr? If you’re using 4096 block sizes did you partition the drives starting at sector 2048? Did you turn off compression if you don’t need it? Also consider your hardware, like if you have multiple connection ports, can you get a speed increase by spreading out the drives so you don’t saturate any particular channel?

    Newer hardware by itself can make a huge difference too. My last upgrade took me from PCIe x4 to x16 slots, allowing me to upgrade to SAS3 cards, and overall went from around 70MB/s to 460MB/s transfer speeds with enough hardware to manage up to 40 drives. Turns out the new configuration also uses much less power, so a big win all around.









  • I feel like I want to agree with you, but on the other hand what would happen if everyone were free to use any dead celebrity’s likeness any way they wanted? Keeping in mind that Sinéad O’Connor’s estate just sued Trump for using her music without permission at a rally that goes against everything she stood for, if we weren’t allowed to keep a tight reign on these things then it would unleash some truly unspeakable horrors. For example, what if a speech from MLKJ were allowed to be twisted by white supremacists to spread hatred? It could get out of hand so quickly and the good deeds done by these people could be white-washed. I think we just need to accept certain restrictions in order to safeguard the strongest voices that speak up for the rest of us.




  • I was considering POE as an option, and this camera does have an ethernet port (although I can’t tell yet if that’s only for configuration or if the video will also stream over it directly). I don’t really need a constant stream and this camera also provides motion options so maybe it would only send video as needed (although during a heavy storm all of the cameras would probably fire at once).


  • I played with Zoneminder years ago but would like to get something set up for home security. I have a full internal network plus servers and about 60TB of free storage space so there’s really no limitations to what I could set up. Ideally I’d like to just hit a local IP from a cell phone to check the cameras (and remote access isn’t really needed), so that’s where I was trying to go with my previous questions.

    The software side seems easy enough, but finding compatible IP cameras has been stumping me. I see the Reolink 4K TrackMix wifi cameras on Amazon for $130, and other than a few hiccups it looks likely that this piece of hardware would work, unless anyone knows of any “gotchas” that I’ve missed? Otherwise I’ll do a bit more research and then order one of the cameras to see how far I can get with it.
