  • No, there will absolutely be a fight.

    The moment Trump fully realizes how incredibly he's lost, he will immediate switch to military threats to save face.

    He has no choice, it's one thing if the American economy collapses, but his ego is at stake here!

  • I'm gonna have to donate then.

  • Why is my server using all my Swap but I have RAM to spare?

    Jump

  • It pushes stuff when they're really really cold, so for instance init services and libs that have basically never been touched since boot but still technically need to be in memory.

    They might have been pushed out because the page cache thought it had something more interesting, or if you have VMs, because the system wanted to make some huge pages.

  • Filesystem and virtualization decisions for homeserver build

    Jump

  • It's good, but be aware you want to stick to LTS kernels or at least don't upgrade casually.

    Arch is the worst for this, ubuntu and debian are better but still get hit.

    Hit this recently on an arch build, switched to kernel-lts and it worked, but basically once every year or so the abi breaks and zfs is dead for 3-6 months on github.com/torvalds/linux@master. Just FYI.

  • FYI, zfs is pretty fucking fragile, it breaks a lot, especially if you like to keep your kernel up to date. The kernel abi is just unstable and it takes months to catch up.

    Which is part of why I don't trust zfs on root.

    Worst case you can sometimes recover with zfs-fuse.

  • German poll: Majority for return to nuclear energy

    Jump

  • https://en.wikipedia.org/wiki/HTR-PM

    China has the pbr in production as modular reactors.

    When the reactor temperature rises, the atoms in the fuel move rapidly, causing Doppler broadening. The fuel then experiences a wider range of neutron speeds. Uranium-238, which forms the bulk of the uranium, is much more likely to absorb fast or epithermal neutrons at higher temperatures. This reduces the number of neutrons available to cause fission, and reduces power. Doppler broadening therefore creates a negative feedback: as fuel temperature increases, reactor power decreases. All reactors have reactivity feedback mechanisms. The pebble-bed reactor is designed so that this effect is relatively strong, inherent to the design, and does not depend on moving parts. This negative feedback creates passive control of the reaction process.

    Thus PBRs passively reduce to a safe power-level in an accident scenario. This is the design's main passive safety feature

    The west is irrationally afraid, but China understands nuclear is inherently safer than fossil fuels after having lost thousands to pollution.

    Cancelled pushbullet for it, it's incredible.

  • German poll: Majority for return to nuclear energy

    Jump

  • Those are old designs, new ones basically stop once the water is removed.

    Hence the 'negative void coefficient', modern designs lose reactivity as the water is removed.

    Look at pebble bed and other designs.

    Are you being semantic?

    They realized the revenue as dividends, which is exactly what the link says.

  • Nfs, it's good enough, and is how everyone accesses it. I'm toying with ceph or some kind of object storage, but that's a big leap and I'm not comfortable yet

    Zfs snapshot to another machine with much less horsepower but similar storage array.

    Debian boots off like a 128gb Sata ssd or something, just something mindless that makes it more stable, I don't want to f with Zfs root.

    My pool isn't encrypted, don't consider it necessary, though I've toyed with it in th past. Anything sensitive I keep on separate USB keys and duplicate them, and I use luks.

    I considered virtiofs, it's not ready for what I need, it's not meant for this use case and it causes both security and other issues. Mostly it breaks the demarcation so I can't migrate or retarget to a different storage server cleanly.

    These are good ideas, and would work. I use zvols for most of this, in fact I think I pass through a nvme drive to freebsd for its jails.

    Docker fucks me here, the volume system is horrible. I made an lxc based system with python automation to bypass this, but it doesn't help when everyone releases as docker.

    I have a simple boot drive for one reason: I want nothing to go wrong with booting, ever, everything after that is negotiable, but the machine absolutely has to show up.

    It has a decent ups, but as I mentioned earlier, I live in San Jose and have fucking pge , so weeks without power aren't fucking unheard of. I'm away from home so it has to come back after the fairly regular outages. I have some leeway, but my entire infrastructure is on it, so not much.

  • Rand Paul Fears Trump Tariffs Could Mean 1930s-Style Republican Wipeout: ‘We Lost the House and Senate for 60 Years’

    Jump

  • Nah.

    The civil war resulted in the horribly and completely evil south being knocked out of national political dominance for decades.

    That led to the rise of the US as a global super power, including the transcontinental railroad and the progressive movement of Teddy Roosevelt.

    Their return to political prominence is accompanied by the fall of America as the greatest hyperpower in human history.

    As soon as the war is over they return all lands and prisoners, and pay full reparations.

    Otherwise, we need to help Ukraine kill as many of their kids as possible, and we should watch the videos and laugh. :)

    The TCJA generally eliminated taxes on dividends, or repatriated earnings, to U.S. multinationals from their foreign affiliates. Dividends of $776.5 billion in 2018 exceeded earnings for the year, which led to negative reinvestment of earnings, decreasing the investment position for the first time since 1982. Tables 3 and 4 provide information on the country and industry breakdown of dividends.

    By country, nearly half of the dividends in 2018 were repatriated from affiliates in Bermuda ($231.0 billion) and the Netherlands ($138.8 billion). Ireland was the third largest source of dividends, but its value is suppressed due to confidentiality requirements. By industry, U.S. multinationals in chemical manufacturing ($209.1 billion) and computers and electronic products manufacturing ($195.9 billion) repatriated the most in 2018.

  • What steps do you take to secure your server and your selfhosted services?

  • Have the rack mounted one, I usually roll my own router but I'm glad to have someone else making sure I don't do anything stupid for security.

    It's not perfect, but it's peace of mind.

  • Zfs on Debian on bare metal with nfs server. Edit: and it hosts the worker vms

    Vlan for services with routed subnet

    Sriov connectx4 with 1 primary vm running freebsd and basically all my major services in their own jails. Won't go into details, but it has like 20 jails and runs almost everything. (had full vnet jails for a while which was really cool but performance wasn't great).

    1 vm for external nginx and bind on Debian vm on isolated subnet/Vlan and dmz for exposed services

    1 vm for mailinabox on dmz subnet/Vlan

    1 Debian vm on services vlan/net for apps that don't play well with freebsd, mostly dockers, I do not like this vm, it's basically unclean and mostly isolated.

    Few other vms for stuff.

    It's a Dell r730 with 2 2697(or 2698? 20c/40t each) with 512gb. Edit: v4 so broadwell

    12x16tb hgst h530s with 2 nvme drives and 2 Sata ssds, somewhere in there is a zlog and l2arc.

    Can't figure out how to fit a decent GPU in there so currently it's living on my dual Rome workstation, this system is due for an upgrade, thinking about swapping the workstation to a much lighter one and push the work to the server, while moving the storage to a dedicated system, but not there yet.

    Love freebsd though, don't use it as my daily driver, tried a bit, it worked but there was just enough trouble to not make it work, but freebsd has moved on and so have i, so it's worth a shot again.

    Decent i/O, but nothing to write home about, think it saturates the 10g but only just, I have gear for full 100g (I do a LOT of chip startups, and worked at a major networking chip firm a while) but it takes a lot more power, and i have PGE so I can't justify it till I can seriously saturate it.

    Also I'm in process of moving to Europe, built a weak network here and linked via wire guard, but shit is expensive here and I'm not sure how to finish the move just yet, so I'm basically 50/50 including time at work in the valley.
