  • If you’re skeptical that this feat is possible with a raw 4004, you’re right: The 4004 itself is far too limited to run Linux directly. Instead, Grinberg created a solution that is equally impressive: an emulator that runs on the 4004 and emulates a MIPS R3000 processor—the architecture used in the DECstation 2100 workstation that Linux was originally ported to. This emulator, along with minimal hardware emulation, allows a stripped-down Debian Linux to boot to a command prompt.

    that is 2^8 levels of insane! and of course its Debian.

    edit: 4bit data 12bit addressing make it an 8bit processor ; -)

    I will slowly corrode on this hill.







  • someone genuinely interested for intellectual reasons would likely not fall for it. I would imagine that a non-trivial percentage of “antiquity enjoyers” are very light on history substance and heavy on history feelz.

    once the appropriate brain tickles have been pushed into their heads their “history substance” feed content becomes decidedly propagandized.


  • this is really, really interesting. thank you for this.

    instance reach and relationships are pretty wild and I can see this helping people to mix up their communities between instances.

    the tight groupings of some instance communities might be source of pride or distress, depending.

    would be nice to select a community and query its n closest overlap neighbors or all neighbors within a certain distance.

    very cool project.



  • no worries.

    the net effect of client separation is that your device sees no other layer 2 devices on the wlan besides the gateway. this would typically be enforced at the frame level by the APs and is separate from any radio privacy cryptography.

    a properly configured wireless setup would assume every client is compromised and would also disallow local client-client via source routing or proxy ARP or any other escape options. 100% secure? probably not, but its a non trivial barrier that would have to be circumvented.

    as with e.g. broken WEP years ago, there are still options to mess with clients at ~Layer 1 but I dont believe its currently as trivial as it used to be.





  • I would say yes. I have never used a pure sinewave UPS outside of a data center situation and all of those are on-line units as opposed to line-interactive anyway. I have personally never seen an issue with stepped sine UPS units on typical pro/consumer workloads.

    lots of small and mid sized shoestring budget deployments make use of “economical” (but name brand) UPS units on legit sensitive equipment without fuss.

    edit to add: of course, if your mains supply is absolute garbage, then a better quality can make a difference. if utility is clean and the UPS will just be doing ocassional brown/black out duty, then I would not spend more on a sinewave UPS.
