  • It’s not that simple. It’s not just a “this is or isn’t AI” boolean in the metadata. Hash the image, then sign the hash with digital signature key. The signature will be invalid if the image has been tampered with, and you can’t make a new signature without the signing key.

    Once the image is signed, you can’t tamper with it and get away with it.

    The vulnerability is, how do you ensure an image isn’t faked before it gets to the signature part? On some level, I think this is a fundamentally unsolvable problem. But there may be ways to make it practically impossible to fake, at least for the average user without highly advanced resources.

    Updating my computers from Ubuntu 22.04 to 24.04 was a whole day process. It doesn’t help that the upgrade tool requires you to press enter every so often.

    (Yeah yeah I should try other distros. I’ll play with other distros when I’m not spending my time as pictured in the meme.)

    (To be clear this is on a couple computer I personally own. The ones the lab owns are on Ubuntu 20.04 if I’m lucky…)





  • I’d recommend looking for keyboards with hot-swappable switches. They may be more expensive up front, but they are repairable so they will be much more cost effective in the long term. Plus there are fun things you can do like trying out different switches or even mix-and-matching different types.

    I usually have a key fail about once a year or so. For a keyboard without hot swappable switches that’s a new keyboard each time one key fails (assuming it’s a key that’s important, which it usually is - keys you use more frequently are more likely to fail sooner). Keys are like $1 a pop (although you usually have to buy them in bulk).

    I used to buy the Corsair keyboard for like $50 each. I switched to a $150 keyboard with hot swappable switches. I’ve had my keyboard for about 5 years now and I think I’ve replaced 3 keys.










  • When it does happen, hackers will be able to decrypt any vulnerably encrypted messages they capture now. We need to switch to post-quantum encryption well before quantum computers that can break encryption actually are built, such that any data they do actually decrypt is old enough it’s worthless.

    But the real reason why Microsoft is doing this now is simply because the decision on which algorithms should be the first official standard for post-quantum encryption have just been finalized. Expect a lot of companies to be adding post-quantum encryption in the next couple years.
