Giants Opening Day Lineups Through the Years

stumbled upon this...I'm sure many ppl have seen this, so I don't claim to have discovered it for the first time...but I am so glad baseball, and +San Francisco Giants​, is back! 
View the Giants historical Opening Day lineups.

wow...hmm...yeah...I guess I have no choice
 
This is the most demonically clever computer security attack I've seen in years. It's a fabrication-time attack: that is, it's an attack which can be performed by someone who has access to the microchip fabrication facility, and it lets them insert a nearly undetectable backdoor into the chips themselves. (If you're wondering who might want to do such a thing, think "state-level actors")

The attack starts with a chip design which has already been routed -- i.e., it's gone from a high-level design in terms of registers and data, to a low-level design in terms of gates and transistors, all the way to a physical layout of how the wires and silicon will be laid out. But instead of adding a chunk of new circuitry (which would take up space), or modifying existing circuitry significantly (which could be detected), it adds nothing more than a single logic gate in a piece of empty space.

When a wire next to this booby-trap gate flips from off to on, the electromagnetic fields it emits add a little bit of charge to a capacitor inside the gate. If it just happens once, that charge bleeds off, and nothing happens. But if that wire is flipped on and off rapidly, it accumulates in the capacitor until it passes a threshold -- at which point it triggers that gate, which flips a target flip-flop (switch) inside the chip from off to on.

If you pick a wire which normally doesn't flip on and off rapidly, and you target a vulnerable switch -- say, the switch between user and supervisor mode -- then you have a modification to the chip which is too tiny to notice, which is invisible to all known forms of detection, and if you know the correct magic incantation (in software) to flip that wire rapidly, will suddenly give you supervisor-mode access to the chip. (Supervisor mode is the mode the heart of the operating system runs in; in this mode, you have access to all the computer's memory, rather than just to your own application's)

The authors of this paper came up with the idea and built an actual microchip with such a backdoor in it, using the open-source OR1200 chip as their target. I don't know if I want to guess how many three-letter agencies have already had the same idea, or what fraction of chips in the wild already have such a backdoor in them.

As +Andreas Schou said in his share, "Okay. That's it. I give up. Security is impossible."

first time serving on a jury...it's been quite interesting and exciting thus far...i get some time to explore an area of San Francisco that I wouldn't normally spend much time in, during the day time, which I wouldn't normally get the chance to due to normal work hours...the best part, however, I discovered today, is that i get to catch +San Francisco Giants​ opening game during my 1.5-hour lunch! so worth it!

trying to balance play time with work time...
Introduction
i just want to play!!!

napping/sleeping in is the best =) but hanging out with friends and staying up late together isn't too bad, either...i like exercising out in the sun, watching movies, shooting games, listening to music, and just having a good time generally...oh there's work thrown in there somewhere...

i grew up in taiwan, and if you'd let me, i will spend all day arguing for taiwanese independence...

things i post/circles to put me in:
  • sports/fitness (soccer, baseball, snowboarding, running)
  • music (my favs are maroon 5 and queen, but i love basically all music)
  • random prose that inspired/interested my thoughts
  • clouds and giraffes!
