Mikayla has passed away. Ethan made a statement.

SaveAFox will be holding a celebration of life on July 12. The fundraiser is still active to help the remainder of the 500 foxes from the farm.

An unimaginable loss for the rescue

@crashdoom Hard mode: Scramble after every key hit

Also, here’s a good visual demonstration of how they work: https://youtu.be/aKK6tlvxios.

You present your access card to the reader, it scrambles the location of the numbers across the pad several times, then stops on a final location for all the numbers.

That’s also where I’d fumble by getting an anxiety spike seeing the numbers move rapidly and forgetting / mistyping the PIN xD

Okay so like.. anyone else had the (dis)pleasure of working in a building with one of these fucking things? XD

For those that don't know, it's a Hirsch ScramblePad reader!

When you scan your access card, the pad lights up and rapidly randomizes all the numbers on the keypad several times before giving you a final layout to use to enter your PIN.

They also had an extremely small viewing window that meant anyone not immediately in front of the keypad (or standing to the side) /shouldn't/ be able to see the numbers on the pad, thus shouldn't be able to figure out your PIN.

Hoooowever, at least for myself, I couldn't ever successfully enter my PIN on the first go from fumbling reading the numbers properly XD

When I was in high school, Mythbusters was the only notable example I could point to of nerds being "cool".

(This was a time when you were made fun of for liking anime or being more into books than gossip.)

You can hear Adam hold back tears of joy at several moments in the video.

In the middle of this section about connecting the R36S to WiFi…

“garbage is chicken ribs”

"Report all foreign invaders."

We are not Nazi Germany. Do not comply. Do not collaborate with this fascist administration.

Fuck this. Fuck Trump. Fuck the Republican Party for endorsing this domestic terrorism and nazi bullshit.

Eeee! Signed G’raha art card! Heck yes! :3

Heck! The two FF MtG bundles we ordered arrived early 👀~

I'm really glad Apple came around to the idea Google had ages ago with Call Screening... One thing I really missed from my Pixel xD

Kind of strange that the push to voicemail thing came first, felt like it was missing something but kinda good enough at the time 🤔

@crashdoom Hard mode: Scramble after every key hit
@Doridian Congratulations, you made me check the dipswitch configuration on them, lmao.. THANKFULLY, they didn’t add that— It’d be hella secure, but fml noooooo xD

@crashdoom If you want another random idea I had seeing these: Why not make every key a fingerprint reader, and only take keypresses on a match?

I'd build one myself but I don't think I can get clear fingerprint reader modules anywhere to do it with x3

@crashdoom @Doridian My brain would crash and need a reboot to recover from the situation 😂

@l4p1n @Doridian me IRL every time I had to get into my work building each day lmao

[randomizes] “Yeah, PIN is— is… uhh… fuck.” 😵‍💫

It shouldn’t be that hard only randomizing once lmao tho, every time would be.. impossible

@crashdoom the idea itself is really cool actually.
@crashdoom fascinating, never seen one of those before!

@crashdoom I’ve never seen that but it’s really cool actually

Normally stuff like this is kinda security theatre-y and provides a minimal benefit for the hassle but this seems like a genuinely good idea that actually addresses an otherwise piss-easy attack without that much hassle

I’m definitely not saying every building should have one of these but it’s nice to see a security product with a gimmick that makes some sense actually. :3

@crashdoom Didn't know that exists Oo
@tisha @crashdoom security measure against a common pin number being easy to decipher because the numbers get worn down by repeatedly entering it.
@TheMNWolf @crashdoom Yes, but I honestly didn't think anyone cared! 😹
@tisha @crashdoom never underestimate the laziness of those who make the security choices. I can't tell you how many places I've worked where the system required a secure password, but then they made everyone on the team use a single login and they just taped the password to the monitor.

@TheMNWolf @tisha Bingo! Keypad wear is a HUGE indicator of a commonly used access code.

If you’ve ever seen those metal push button door locks that have two rows of numbers / letters, usually on a common staff room door, you can figure out the code by checking the wear of the buttons.

If it’s loose / worn, probably part of the code (or at least a common one).

If you find 4 worn common pads, you might have all the digits of the code, just need the order :p

@crashdoom @tisha and a lot of those mechanical push button locks don't actually care what order you press the buttons in.
@crashdoom grapheneos implements this for the android lock screen but i had no idea this existed in the form of hardware that's cool

@crashdoom there are a few doors I deal with regularly that have these.

My annoyance is that the bottom left and right keys don’t illuminate, but I am supposed to press # when I’m done entering my code.

@tango Fascinating.. we were always instructed never to use the two side buttons unless under duress. Though, yeah, they weren't ever illuminated for us either!
@crashdoom # is the bottom right
@crashdoom @tango I guess the duress code is programmable? One facility I worked at recommended (finding and) pressing 9 after your regular pin. Which, now I think about it, is daft because your captor sees you press 5 instead of 4 keys, and the jig is up.
@darac @crashdoom our codes can have varying lengths, thus a need to indicate you have finished.
@crashdoom I used to work in a government building with these. We set the number to 12333
@crashdoom I worked at a place that had a PIN pad that looked like that circa 2025 or so but at my current job we just have some kind of NFC card which my Sony FeliCA reader can't see
