  • And what “ethnicity” is that supposed to be? “White” Jews are for the most part ethnically and largely also genetically indistingishable from central Europeans.

    US Americans have a strange obsession with “race”, and Zionists played right into that by establishing the false idea that Jewishness is a race or ethnicity.

    In Europe this is a very uncommon view by the way, and most people consider Jewishness a purely religious description and the last people that tried to make it an ethnic description were literal Nazis.



  • Eh, I find that not very convincing, especially when distinct religious groups like the Ethiopian Jews and other such groups exist that have very little other than religion in common with the dominant group that is commonly referred to as Jews.

    Confusing Jewishness and Judaism with culture and ethnicity is IMHO a tactic that Zionists (and funnily enough also antisemites) use to push their agenda and it usually comes with discrimination of other Jews like for example those from Ethiopia.

    And most Christians in Europe are also not very religious.




  • Well usually the opposite happens. People make many releases and outsource the testing to unsuspecting users.

    This is IMHO fine if you clearly mark these releases as release candidates or such, so that people can make their own risk judgement. But usually that isn’t the case and one minor version looks like any other unless you have a closer look at the actual changes in the code.



  • “Bigger” is a bit missleading here. Really bigger updates obviously require a major version bump to signify to users that there is potential stability or breakage issues expected.

    But “bigger” in the other sense i.e. meaning slower, means that there was more time for people to run pre-release versions if they are adventurous and thus there is better testing.

    Of course this assumes that there are actual beta testers and that it is easy to do so by creating such beta releases.

    Yeah, running it like that here. Works fine for the most part, except that the hybrid inverter that I bought advertised “UPS” mode, but it doesn’t actually switch fast enough to avoid also adding a proper UPS (but running an UPS chained is another issue…).

    It sounds a bit strange as it does actually run off the battery all the time (unless below the minimum charge limit, when it seamlessly switches to grid power automatically), but due to legal requirements it needs to switch to another supply mode when the grid power fails and this switch is not entirely seamless on my inverter.

    As usual it depends (and TDPs are highly misleading). First of all the 6700k is a 14nm chip, Vs. 32nm for the E5-2620. And the 6700k is a Skylake generation chip, compared to Sandy Bridge for the Xeon, which brings significantly better power-states. But on the other hand the 6700k is much higher clocked and has turbo-boost, with the latter being notoriously power hungry (can be disabled in the bios though).

    In my educated guess the 6700k will use significantly less power if it mostly idles or does only burst tasks, which is actually what most self-hosters have as as task-loads. But if you serve websites to thousands of users which results in a consistently high CPU load, the Xeon is probably overall the better chip, including power-consumption under load.

    Edit: I realized now that it is a E5-2620v2, which is Ivy Bridge and 22nm. So the difference is probably less, but overall the same considerations apply.


  • Really depends on the specific workload.

    Another thing to keep in mind is that the 6700k is significantly more power efficient, especially when it isn’t consistently under high load.

    Also if you do any sort of media processing the 6700k has a gpu and quicksync built in that can speed these things up significantly.

    It nearly certainly happened to you, but you are simply not aware as filesystems like ext4 are completely oblivious to it happening and for example larger video formats are relatively robust to small file corruptions.

    And no, this doesn’t only happen due to random bit flips. There are many reasons for files becoming corrupted and it often happens on older drives that are nearing the end of their life-span and good management of such errors can expand the secure use of older drives significantly. And it can also help mitigate the use of non-ECC memory to some extend.

    Edit: And my comment regarding mdadm Raid5 was about it requiring equal sized drives and not being able to shrink or expand the size and number of drives on the fly, like it is possible with btrfs raids.


  • One of the main features of file systems like btrfs or ZFS is to store a checksum of each file and allow you to compare that to the current file to notice files becoming corrupted. With a single drive all btrfs can do then is to inform you that the checksum doesn’t match to the file any longer and that it is thus likely corrupted, but on a btrfs raid it can look at one of the still correct duplicates and heal the file from that.

    IMHO the little extra space from mdadm RAID5 is not worth the much reduced flexibility in future drive composition compared to a native btrfs raid1.
