Not sure if I missed it, but did anyone look into Knuth's volume 3 to see if it shows up there ? Don't have my copy handy


has anyone tried the circuit design component on the tinkercad site https://www.tinkercad.com/ ?


All I can think about is the episode of "family guy" where Peter has birds nest in his beard


It is a beautiful place to go hiking. You probably remember kinuseo Falls and the monkman cascades? The area is now a UNESCO Global Geopark.


Yes! When I lived there, there was no bridge to Kinuseo, so you had to drive through the Murray. I crossed with a friend who had a lifted Dodge 4x4. It was more than a little un-nerving to have water starting to fill the cab...

The other thing I remember is that the Conservation Service used to catch poachers up in that area with "robot" deer (IIRC, the extent of the automation was that the heads turned).


looks like someone screwed up a club sandwich


I still have my original hp-15C and the owner's handbook with a print date of 2/84


not sure if you are aware of this story concerning Blackberry

https://motherboard.vice.com/en_us/article/mg77vv/rcmp-black...


I hadn't seen that story, thanks for linking it. Just to clarify, that story is about consumer BlackBerrys which were known to be insecure, where the keys were at the mercy of RIM's willingness to protect them.

I was talking about enterprise BlackBerry systems being unbreakable to governments. That story does not contract this. However, it's saddening to hear that RIM apparently coughed up the keys for consumer BlackBerrys even though it didn't face an existential threat. If they had refused, I doubt that they would have been banned in Canada, being their home turf and a darling of the Canadian industry at the time.


I believe you are correct. Blackberrys connected to a BES were end-to-end encrypted before that became mainstream. The key was only stored on the device and on the server.

For consumer services the story is very different.



Thanks for pointing that out! I didn‘t know that he did it as well, I just think its a really good way to visualize the data and to draw some conclusions from it.


here is a youtube video (https://www.youtube.com/watch?v=8Vc-69M-UWk) from 2014 that demos the technique on pin pads and refers to the following paper https://cseweb.ucsd.edu/~kmowery/papers/thermal.pdf
