God I hate that video, he explains everything so badly to the point of completely misinforming viewers. He’s talking about a special situation of AC current, but uses DC in the thought experiment. He makes it seem as if the field travels to the load in a direct path and the wires don’t matter. No, the EM field is completely based on the wire.

In my head I thought one could make relatively cheap high capacity in 2.5" SATA form factor by having more NAND chips of lower capacity. You give up speed and PCB space but that’s fine since bandwidth and IOPS are limited by SATA anyway and there’s plenty of space compared to M.2.

Turns out to not shake out that way, controller ICs that support SATA aren’t coming out any more, and NAND ICs are internally stacked to use up channels while not taking up PCB space.

There are some enterprise options, but they’re mad expensive.

I have 4x 6TB HDDs in my NAS. Around 5 years ago I decided to simply replace any dead drives with 6TB ones instead of my previous strategy of slowly upgrading their size. I figured I could swap to 8TB 2.5" SATA SSDs that had just started to exist and would surely only get cheaper in the future…

Back in the day I used a raspberry pi 3 for 1080p h.264 and steam link / moonlight. Problem was omxplayer plays up to 1080p60 beautifully, but anything else would struggle. Eventually ‘upgraded’ to an old laptop to easily YouTube/netflix in the browser too.

I fucking love copyparty. It starts simple enough but then the millions of options and configs let you twist it into exactly what you need.

As someone that runs a server OS that doesn’t support docker, it is very refreshing to see a single binary project. It has a focus on being administrator friendly thats really fallen out of fashion these days.

Yeah true the index headset wasn’t a bargain compared to the quests that were clearly being sold as cheaply as possible.

I think it would be fine. Friend of mine has Immich on a N100, like you mentioned, the initial ML tasks on a big library takes over 24 hours but once it’s done it doesn’t need much. I don’t have experience running next cloud but the others you mentioned don’t need much RAM/CPU.

ZFS doesn’t need much RAM, especially for a two disk 4TB mirror. It soaks up free RAM to use as a cache which makes people think it needs a lot. If the cache is tiny you just end up hitting the actual speed of the HDDs more often, which sounds within your expectations. I dare say you could get by with 8 GB, but 16GB would be plenty.

I’d only point out if you’re looking for it to last 10 years, a neat package like the ugreen might bite you. A more standard diy PC will have more replaceable parts. Would be bigger and more power hungry though.

Can get an ‘aoostar GODY’ on AliExpress for US$1000. Basically the same GPU, 16GB RAM, 512GB SSD. The steam machine has less cores and less ethernet. Though it also has a way bigger heatsink, LEDs and extra Bluetooth/valve gamepad antenna.

Comparing the deck to comparative brands, it is wayyy cheaper. I think valve are going to be aggressive on price, especially when the CPU/GPU are fairly old and meek.

They’ve been seen using TM SGNL made by Israeli company TeleMessage to archive messages. Which is good except that it does so unencrypted, giving Mossad a window into the administration…

That is fricking sick dude!

I don’t understand. Police can track you down via your credit card, your phone, your licence plate on your car, rando security cameras. All of these are hard to avoid. How often does your ID not just get checked, but recorded? It seems like not much of a game changer.

I think you’re connecting digital IDs with people’s online activity for some reason. In most countries, authorities can already connect online activity with an individual, since you register and pay for internet. Doing things that the powers that be don’t like will get you in legal trouble. Remember the 2000s when the music industry sued individuals for millions? In China they take down your post if it challenges social cohesion, in the USA they take all of your money and assets for challenging corporate revenue.

Most digital IDs are options for people that already have their bank/credit card on their phone and don’t want to carry a wallet just for ID. Some places like Estonia go further with actual asymmetric keys that let you sign documents with your ID’s private key that proves you signed it.

If it was me, I’d snoop the DNS requests and/or SNI headers. Flag on torrent index sites and trackers known to be used for pirate stuff. They don’t need to know exactly which paw patrol movie you’re downloading, just that you are getting something from thepiratebay.

Ah kay, definitely not a RAM size problem then.

iostat -x 5 Will print out per drive stats every 5 seconds. The first output is an average since boot. Check all of the drives have similar values while performing a write. Might be one drive is having problems and slows everything down, hopefully unlikely if they are brand new drives.

zpool iostat -w Will print out a latency histogram. Check if any have a lot above 1s and if it’s in the disk or sync queues. Here’s mine with 4 HDDs in z1 working fairly happily for comparison:

The init_on_alloc=0 kernel flag I mentioned below might still be worth trying.

After some googling:

Some Linux distributions (at least Debian, Ubuntu) enable init_on_alloc option as security precaution by default. This option can help to prevent possible information leaks and make control-flow bugs that depend on uninitialized values more deterministic.

Unfortunately, it can lower ARC throughput considerably (see bug).

If you’re ready to cope with these security risks 6, you may disable it by setting init_on_alloc=0 in the GRUB kernel boot parameters.

I think it’s set to 1 on Raspberry Pi OS, you set it in /boot/cmdline.txtI think.

Exhaustive ZFS performance tuning guide

sync=disabled will make ZFS write to disk every 5 seconds instead of when software demands it, which maybe explains your LED behavior.

Jeff Geerling found that writes with Z1 was 74 MB/sec using the Radxa Penta SATA HAT with SSDs. Any HDD should be that fast, the SATA hat is likely the bottleneck.

Are you performing writes locally, or over smb?

Can try iostat or zpool iostat to monitor drive writes and latencies, might give a clue.

How much RAM does the Pi 5 have?

Personally I think it’s fallen out of fashion. For my blog I’d either use a meme or other dump picture for each post. When generated images first came out I used a few for blog posts, it was new and interesting and said “I’m interested in technology and like playing around with new things”.

Nowadays I’m back on the meme pics. I feel now it’s so much easier to generate images, it more says “I want to look professional but also spend no money and have no standards”.

Nah bugger that. Famous actors are known by a vast majority of people. It is not normal for open source programmers to receive abuse to the level of death threats. That only happens when you get the attention of kiwi farms types.

I always assumed that Poettering is an arse to people because of the hate he got for systemd. I imagine it’s hard to see the best in people when there’s a crowd of haters everywhere you go. Though I have no idea what he was like beforehand.
