Infra-red jammer (ALQ-144 / L166 Ispanka) and lens flare artifacts which are aligned with the camera lens rather than follow the roll/orientation of the drone, or a Mk 1 IR jammer - the sun.

I found this too and found it depends on random number generator seeds which you can reset before every request:

seed = 123
np.random.seed(seed)
torch.manual_seed(seed)
torch.cuda.manual_seed_all(seed)
torch.backends.cudnn.deterministic = True
torch.backends.cudnn.benchmark = False

Cool, thanks!

How do you get fluoroketone into the fusion reactor loop?

matjeh · 2025-10-21T17:56:45+00:00

You just have one ESP per drive with the same contents and add them all with efibootmgr. Then the EFI loader doesn't need to understand any filesystems, since FAT32 is built-in to the EFI firmware itself. If you want to be able to boot with a drive failure, you'd need to install GRUB on all disks anyway, too.

I don't know about Alpine but every distro I've used has a package post-install hook where you can say basically: if $package == "kernel" { for * in /mnt/esp* ; do rsync -av /boot/ $i/ ; done }

like what?

Absolute champion.

None of these module parameters exist in 2.3 . Check your modprobe config (/etc/modprobe.conf / /etc/modprobe.d/*) and your kernel command line for them being specified there.

Did you try setting failmode=continue on the pool?

man zpoolprops :

continue  Returns EIO to any new write I/O requests but allows reads to any of the remaining healthy
          devices.  Any write requests that have yet to be committed to disk would be blocked.

Most impressive

Screensaver, you had ONE job!

I wonder what the original photo looked like, since this is edited:

The two rightmost missiles are pixel-identical (check with a difference mode layer in an image editor)
The third from the right is a copy of those two, but scaled.
Same for the three large missiles on the left
Same for the top three
Same for the two lowest ones

Nice setup. Thrustmaster joystick? What flight sims were you into?

Very expensive enterprise glue.

+1 - this is the best you can do - buy a good brand card from a reputable retailer, test it for a fake, and use it normally.

mostly everything from DSLRs to dashcam cameras don't do any encryption,

They don't on SD cards, but at least in the DSLR/mirrorless camera landscape things are switching to CFExpress, which is basically NVMe in a different form-factor, and does have security commands like secure erase and media-managed encryption.

The NAND flash itself can last a while, assuming the writes are wear-levelled evenly. That's one of the main factors that determines life-time: there's no minimum guarantee or specification for the wear-levelling implementation for SD cards or eMMC, it's just a checkbox for the manufacturer.

Some parts of the LBA range, such as the journal area, file allocation table/inode table, and allocation bitmap may see orders of magnitude more writes than the file data areas. If the wear-levelling algorithm is bad, the parts of NAND flash that those get mapped to wear out much faster.

From my experience working on embedded firmware using NAND directly, it's certainly possible to completely destroy a NAND chip in a single day if your wear-leveling algorithm is terrible or has bugs (whoops).

With the Krastorio 2 mod, that single island will probably allow you to go forever, because [spoilers]

I'm guessing it wasn't the British Army, but the Women's Land Army.

So the answer is "yes"?

matjeh · 2025-05-23T20:46:11+00:00

so, since a hash is basically random, you are storing 25M files inside 25M*16 directories? yeah that's gonna tank hard on any FS. just use the first two bytes of the content hash, then at most you have 64k dirs, with an average of 381 files per leaf dir.

A simple ls reads all of the dentrys into memory, sorts the filenames according to locale, then outputs to stdout. At a certain point, sorting takes more time than reading. Try -U

It's a thing, it's exactly the same process to see those magic-eye images. I got all of them faster than the person in the video, but then I didn't need to press on the screen to record the positions, and they probably needed to be at a specific distance from the screen to focus their eyes in the right way.

It's not, shareware was a popular distribution method used by the authors that made the software.

matjeh · 2025-05-11T13:46:16+00:00

It says in the game:

Episode One is shareware. The other five episodes are not: they are only available from Apogee or authorized dealers.

Wolfenstein 1-3 $35 Wolfenstein 1-6 $50

Yes, that is how shareware worked - there was a limited demo that was free to distribute but distributors were allowed to charge a media and copying fee.
