  • 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.







  • Software passkeys can’t provide attestation and don’t. A service requiring it would reject every apple and google device too. Its a feature for hardware like yubikeys and smart cards used by governments to ensure it’s not a knockoff with backdoors.

    No thats actually not an issue at all if your device is secure and uses full disk encryption.

    Oh I see your computer is secure well then nothing to worry about 🤣

    If i want to write down my private key on a piece of paper and type it in by hand then thats my issue to deal with and not theirs.

    With a hardware FIDO2 key, the private key never leaves the device, instead it signs challenges. Malware on the PC can’t access the private key and make it’s own copy.

    Using software keys, they are at least encrypted in the vault until you open it, then there’ll be a window of time with a plain copy in memory that malware can potentially grab.

    Your plaintext private key file can be stolen by malware easily and immediately. You would actually be better off with it written on a post it note.

    Course in real life malware is gonna be stealing your browser cookies to gain access to your accounts and avoid the whole keypass thing. In the world that FIDO was born, authentication is happening all the time and any possibility of key theft is considered a compromise.




  • 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?


  • OpenAI noticed that Generative Pre-trained Transformers get better when you make them bigger. GPT-1 had 120 million parameters. GPT-2 bumped it up to 1.5 billion. GPT-3 grew to 175 billion. Now we have models with over 300 billion.

    To run, every generated word requires doing math with every parameter, which nowadays is a massive amount of work, running on the most power hungry top of the line chips.

    There are efforts to make smaller models that are still effective, but we are still in the range of 7-30 billion to get anything useful out of them.


  • 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”.
