  • Might be a bit late on this, but ProxMox doesn’t really handle assigning threads to the e/p cores. That’s handled by the kernel and as long you’re running kernel version 6.1 or greater you should be good on that front.

    If you really need to, you can also pin specific VMs to specific cores. So that if you’ve got something that always needs the performance it can always run on the p-cores and things that aren’t as demanding can always run on e-cores.

    That said, especially if you’re over provisioning, it’s probably better to let the scheduler in the kernel handle thread assignments.


  • And 1/2c is a pretty middle of the road escape velocity for a neutron star.

    The lightest known neutron star, at 1.4 solar masses has an escape velocity of right around 1/4c, while the heaviest at 2.35 solar masses is 3/4c.

    All of which assumes the neutron star isn’t spinning. Equatorial bulging caused by the rotation reduces the escape velocity at the equator relative to the poles and depending on whether or not you launch with the direction of the rotation you might be able to subtract the rotational velocity from your escape velocity.

    As an example, in the case of that 2.35 solar mass neutron star, it has a rotational velocity of approximately 0.24c. So of you launch with the rotation you get an escape velocity of 0.5c, whereas if you launch against it you’re looking at more like 0.98c.

    Given that nowhere in the article does it say that 14% of people exclusively play on pre-2000 hardware I don’t find this that surprising.

    I’m more shocked by the last statistic, 11% of American households still use fax. Fax? Fuckin’ why? That’s like saying people still listen to music on Edison cylinders.


  • If I’m reading your example right, I don’t think that would satisfy three either. Three copies of the data on the same filesystem or even the same system doesn’t satisfy the “three backups” rule. Because the only thing you’re really protecting against is maybe user error. I.e. accidental deletion or modification. You’re not protecting against filesystem corruption or system failure.

    For a (little bit hyperbolic) example, if you put the system that has your live data on it through a wood chipper, could you use one of the other copies to recover your critical data? If yes, it counts. If no, it doesn’t.

    Snapshots have the same issue, because at the root a snapshot is just an additional copy of the data. There’s additional automation, deduplication, and other features baked into the snapshot process but it’s basically just a fancy copy function.

    Edit: all of the above is also why the saying “RAID is not a backup” holds true.


  • I don’t think this meets the definition of 3-2-1. Which isn’t a problem if it meets your requirements. Hell, I do something similar for my stuff. I have my primary NAS backed up to a secondary NAS. Both have BTRFS snapshots enabled, but the secondary has a longer retention period for snapshots. (One month vs one week). Then I have my secondary NAS mirrored to a NAS at my friends house for an offsite backup.

    This is more of a 4-1-1 format.

    But 3-2-1 is supposed to be:

    • Three total copies of the data. Snapshots don’t count here, but the live data does.

    • On two different types of media. I.e. one backup on HDD and another on optical media or tape.

    • With at least one backup stored off site.


  • I can’t speak to AI performance, but given you’re stated goal of lower idle power consumption, I’d go with the 14900K, not the KS as you have listed.

    Reason being the $250 price difference between the two, when the KS is just a slightly higher binning of the K with an additional 200MHz on the boost clocks. With that higher boost being something you’re unlikely to practically see without a substantial and robust cooling system, I don’t think it’s worth the extra money.

    The reason I’d go with the K over the 10940X is the lower limit on it’s power consumption. The E cores are very efficient and can down clock substantially meaning it idles at really low power. The 10940X doesn’t have that benefit.

    Beyond that, I’d say look at IPC, per thread, per max sustainable clock of each core, to get a general out look on performance.

    Note: all of the above assumes we’re working within your listed options. My actual recommendation would be an AMD 7800x3d or 9800x3d.



  • The last three bioware games or the last three mass effect games?

    Of Bioware’s last three games, Andromeda sucked, Anthem was an atrocity, but Veilguard was decent, not great like classic Bioware games, but it wasn’t bad, it was at least fun to play and had a decent story and characters.

    Of the last three Mass Effect games, Andromeda sucked, ME3 was great until the Horizon mission then it goes to absolute dog shit, and ME2 was great as a character driven RPG but feels a bit out of place in the franchise as a whole.

    Only in the latter case do I really see a true downward trajectory. In the former there’s a tentative upward trend in the quality of Bioware’s games.




  • There are a few optical storage mediums designed for long term archival storage. Like M-Disc or (as mentioned in the article) pioneers DM for Archive, both of which are still commercially available.

    And provided they’re stored properly, even more general consumer oriented optical media can easily last a few decades. Granted the environmental aspect of “proper storage” (<50% relative humidity, constant temp <80F and >50F) can be difficult to achieve at home in a lot of regions, but generally banks and credit unions have an option to get a safety deposit box which is generally in an environmentally controlled room. Other than that just store your media in an opaque single disc case.


  • Absolutely, I don’t disagree with that.

    I was just sharing my anecdote as a counterpoint to your minor rhetorical point at the end, because at least to me, it’s funny since eating ice cream outside at -10 degrees is a ridiculous thing to do.

    Though, I will note that while ice cream won’t melt at those temperatures, at atmospheric pressure it will still sublimate. So, in that way you could still lose your ice cream without intervention, it would just take a while.






  • It is largely an anti-tampering measure. Without it you could have things injected into the system. For example, a stalker could install a hidden tracking program as a service and then return your phone without you knowing.

    Iirc it’s also a prerequisite for full-disk encryption on modern android. So, without it your user data is available to be dumped in an unencrypted state. Most phone thieves are interested in reselling the phone, so they’re provably not going to go through the effort and risk damage to the phone just to dump encrypted data from the chips directly. However, if it’s just available unencrypted from fastboot why not dump it? They could get info that could be used to blackmail or scam you or people you know. Or they could just sell the data.
