sorry, i shower twice a day and wear deodorant but i just sweat so damn much that i end up smelling within a few hours no matter what :(

I use a PowerEdge T620 as my daily driver, let me assure you the CPU fans at full speed can be heard clearly through 3 closed doors :P

Displaying raw HTML? Sure a fair number of people can pull that off. Actually rendering HTML+CSS with all their many features and a performant JS engine is many orders of magnitude more complex though, which is why there are basically only three browser engines (two if you count Chromium as a WebKit fork)

DaPorkchop_,

Of course, but the original commentor’s claim was that writing a web browser is trivial, not that compiling an existing web browser with some minimal changes is trivial.

DaPorkchop_,

Virtually all modern x86 chips work that way

DaPorkchop_,

Personally I’d be somewhat nervous using dd to edit parts of a text file, but you do you :)

DaPorkchop_,

Sure, but unless they can get the engines started back up in time it’s unlikely to be a pretty landing unless there’s a convenient runway within gliding distance.

DaPorkchop_,

they’re still pretty RISC, using fixed-width instructions and fairly simple encoding. certainly a hell of a lot simpler than the mess that is x86-64

DaPorkchop_,

That said, there are “active” USB extension cables which draw current from the power lines and use it to boost the signal along the data lines

Goodbye Youtube and thanks for all the fish (infosec.pub)

Youtube let the other shoe drop in their end-stage enshittification this week. Last month, they required you to turn on Youtube History to view the feed of youtube videos recommendations. That seems reasonable, so I did it. But I delete my history every 1 week instead of every 3 months. So they don’t get much from my choices....

Wait until they hear about DNS root servers

  • modern NVMe SSDs have much more bandwidth than that, on the order of > 3GiB/s.
  • even an antique SATA SSD from 2009 will probably have much lower access latency than sending commands to a remote device over an ethernet link and waiting for a response
DaPorkchop_,

Well, assuming you’ve already gone through the effort to write a custom kernel module to offload your swap pages to Google Drive, it doesn’t seem like that much of a stretch to have it encrypt the data before transmitting it.

DaPorkchop_,

My point was more that the SSD will likely have lower latency than an Ethernet link in any case, as you’ve got the extra delay of data having to traverse both the local and remote network stack, as well as any switches that may be in the way. Additionally, in order to deal with that bandwidth you’ll need to kit out not only the local machine, but also the remote one with expensive 400GbE hardware+transceivers, plus switches, and in order to actually store something the remote machine will also have to have either a ludicrous amount of RAM (resulting in a setup which is vastly more complex and expensive than the original RAIDed SSDs while offering presumably similar performance) or RAIDed SSD storage (which would put us right back at square one, but with extra latency). Maybe there’s something I’m missing here, but I fail to see how this could possibly be set up in a way which outperforms locally attached swap space.

DaPorkchop_,

reminds me of Costco…

Yeah, they were previously hosted by Curse until Fandom bought out all the Curse wikis and transferred them to their ad-ridden pile of shit

Shame, now it won’t be possible to access Gmail from the Nintendo DS Browser.

DaPorkchop_,

Looks like a graphics driver issue. Are you using the proprietary Nvidia drivers or Nouveau?

DaPorkchop_,

You don’t want to unless you’re just planning on running a web browser or word processor or something, they’re significantly buggier and massively slower than the proprietary driver, and especially so on newer cards.

DaPorkchop_,

Functionally it’s pretty solid (I use it everywhere, from portable drives to my NAS and have yet to have any breaking issues), but I’ve seen a number of complaints from devs over the years of how hopelessly convoluted and messy the code is.

DaPorkchop_,

The recommendation for ECC memory is simply because you can’t be totally sure stuff won’t go corrupt with only the safety measures of a checksummed CoW filesystem; if the data can silently go corrupt in memory the data could still go bad before getting written out to disk or while sitting in the read cache. I wouldn’t really say that’s a downside of those filesystems, rather it’s simply a requirement if you really care about preventing data corruption. Even without ECC memory they’re still far less susceptible to data loss than conventional filesystems.

DaPorkchop_,

What exactly are you referring to? It seems to me to be pretty competitive with both ZFS and btrfs, in terms of supported features. It also has a lot of unique stuff, like being able to set drives/redundancy level/parity level/cache policy (among other things) per-directory or per-file, which I don’t think any of the other mainstream CoW filesystems can do.

DaPorkchop_,

Yeah, although the neat part is that you can configure how much replication it uses on a per-file basis: for example, you can set your personal photos to be replicated three times, but have a tmp directory with no replication at all on the same filesystem.

How likely is this to work? KVM/VFIO Single GPU Passthrough (www.youtube.com)

I’ve been wanting to make a proper switch over to Linux for a while now. I’ve currently have a dual-boot setup but still mostly use Windows. The majority of my games should work without fuss, but I’d like to have a simple solution for running the handful of things that don’t work in Linux, such as my WMR VR headset and a...

DaPorkchop_,

I do this for testing graphics code on different OS/GPU combos - I have an AMD and Nvidia GPU (hoping to add an Intel one eventually) which can each be passed through to Windows or Linux VMs as needed. It works like a charm, with the only minor issue being that I have to use separate monitors for each because I can’t seem to figure out how to get the GPU output to be forwarded to the virt-manager virtual console window.

DaPorkchop_,

I considered a KVM or something similar, but I still need access to the host machine in parallel (ideally side-by-side so I can step through the code running in the guest from a debugger in my dev environment on the host). I’ve already got a multi-monitor setup, so dedicating one of them to a VM while testing stuff isn’t too much of a big deal - I just have to keep track of whether or not my hands are on separate keyboard+mouse for the guest :)

DaPorkchop_,

And Ctrl+shift+alt+win+L to open LinkedIn (seriously, try it!)

DaPorkchop_,

That is very slow, unless the drive is connected over USB or failing or something, a drive of that capacity should easily be able to handle sequential writes much faster than that. How is the drive connected, and is it SMR?

DaPorkchop_,

I don’t see anywhere close to the same amount of political memes on generic meme communities anywhere else i frequent on the internet. Lemmy feels like it consists almost exclusively of political memes.

I guess i wouldn’t mind so much if they were actually funny, but they aren’t. They’re mostly just “haha those people dumb” with zero effort to be funny or clever or anything which could make them interesting after having seen the first 3 or 4 of them.

DaPorkchop_,

bedrock edition (for phones/tablets/consoles/windows 10 store) does

DaPorkchop_,

Have a look around

DaPorkchop_,

What exactly happens when you issue a TRIM depends on the SSD and how much contiguous data was trimmed. Some drives guarantee TRIM-to-zero, but there’s still no guarantee that the data is actually erased (it could just marked as inaccessible to be erased later). In general you should think of it more as a hint to the drive that these bytes are no longer needed, and that the drive firmware can do whatever it likes with that information to improve its wear-levelling ability.

Filling an SSD with random data isn’t even guaranteed to securely erase everything, as most SSDs are overprovisioned (they have more flash cells than the drive’s reported capacity, used for wear leveling and the likes). even if you overwrite the whole drive with random bytes, there’s a pretty good chance that a number of sectors won’t be overwritten, and the random bytes would end up going to a previously unused sector.

Nowadays, if you want to wipe a drive (be it solid state or spinning rust), you should probably be using secure erase - it’s likely to be much faster than simply overwriting everything, and it’s actually guaranteed to make all the data irrecoverable.

DaPorkchop_,

that’s the joke

where does the salt go? wouldn’t it build up in the pipes and cause them to get clogged?

having read all these other comments, i’m now feeling like i should come up with a more creative naming scheme… for what it’s worth, my phone is named bob.

DaPorkchop_,

i’ve taken to running apt inside eatmydata, makes it run way faster since it doesn’t call fsync constantly. granted, you could end up in an invalid state if the power goes out, but that’s what UPSs, laptop batteries and backups are for :)

DaPorkchop_,

people always complain about nvidia drivers on linux, but personally my experience has never required anything more than sudo apt install nvidia-driver

DaPorkchop_,

because that would cost a rather large amount of money, which us working-class peasants famously don’t have

DaPorkchop_,

that’s no different than any “normal” filesystem with a traditional block-level RAID solution

DaPorkchop_,

ZFS lacks some features that btrfs has, such as creating CoW clones of individual files (rather than having to snapshot a whole subvolume).

personally i’ve been using btrfs on pretty much everything for about two years, ranging from multiple >100TB filesystems spanning 8 spinning rust drives to individual flash drives and had very few issues (compared to my experiences with ext4 on mdadm). snapshots/reflink copies have made many of my workflows much easier, adding/removing/replacing devices pretty much Just Work™, and the fact that everything is checksummed gives me a piece of mind i didn’t know i needed. sure, ZFS has pretty much the same featureset, but it’s not in the mainline kernel and seems to lack some of btrfs’ flexibility (from the research i’ve done in the past, like adding/removing disks to an existing pool is still experimental).

what i’m really excited for is bcachefs, which takes what i consider the best features of both btrfs and ZFS and then steps them up a notch (e.g. ability to configure RAID settings and prefer specific drives on a per-file/per-directory level). as soon as it’s stable enough to be mainlined i’ll definitely be migrating most of my btrfs filesystems to that.

DaPorkchop_,

i would generally recommend XFS over ext4 for anything where a CoW filesystem isn’t needed. in my experience, it performs better than ext4 at most workloads, and still supports some nifty features like reflink copies if you want them.

DaPorkchop_,

nouveau is hardly better than software rendering in most cases. heck, for pretty much every GPU from the last decade, it isn’t even able to adjust the GPU clock frequency (so it’s permanently stuck on the lowest frequency).

DaPorkchop_,

you’re assuming the town has internet fast enough to load more than a few pictures of the outside world per decade

DaPorkchop_,

Personally, I’ve been running Debian everywhere (both on my servers and for desktop use) for a few years and I’ve found it much more reliable than Ubuntu. Sure, the repos tend to be somewhat out-of-date (unless you’re on testing, which I’ve started using more and more and have yet to experience any actual problems with), but most of the time it makes no difference and if I really need the latest version of something I can just spin up a Docker container.
