They called it a battery firmware update, but they meant the pages of settings you can change in flash. I was able to dump raw memory from the chip, but I could never figure out which generic microcontroller the battery controller had been

I was actually working on this exact problem in grad school, but gave up when we couldn't start fires (and so did Barnaby Jack, according to Forbes -- http://blogs.forbes.com/andygreenberg/2011/07/22/apple-lapto... ). What put the nail in

There's a practical (for some value of practical) defense against this attack: "Countering Trusting Trust through Diverse Double Compiling." It's fairly clever. http://arxiv.org/pdf/1004.5548 If I recall correctly, here it is in short: 1)

It breaks anonymity. Transactions are public and that static address is public, so anyone can tell how much money that static bitcoin address has received.

node.js isn't interpreted; it uses V8, which is a JIT.

You create a new bitcoin address for every transaction. Some money goes to the actual recipient, and the "change" goes back to your new address. In addition, you can attempt to "launder" bitcoins by executing bogus transactions from yoursel

Looks like I was wrong about the redundant loads. They should probably go away (and indeed you say they do if you put BINARY_OP in its own function).

by swolchok 15y ago
What if you made BINARY_OP a __forceinline ( http://msdn.microsoft.com/en-us/library/z8y1yy88.aspx ) function instead of a macro? Things that the function contains that might disable optimization: a lot of gotos, inline assembly in GO_NEXT

Overcommit seems to have changed somewhat since the "early days," as it's now heuristic. I ran into this once when I couldn't malloc 8 GB on a 64-bit machine because RAM + swap was less than 8 GB. http://www.mjmwired.net/kernel/Documentati

The Hex-Rays decompiler is very good, and I've used it for reversing several times. In particular, it was extremely useful for our analysis of the Green Dam censorware system ( http://www.cse.umich.edu/~jhalderm/pub/gd/ ).

I looked at the list of platforms, and I did not want Greplin to have access to any of them. For example, GMail already has search, Facebook has confidential personal stuff, and Dropbox has confidential work stuff.

by swolchok 16y ago
I just can't trust a service like this with the data they want to search. Google and Facebook are already weak points for privacy; giving one company access to both is a complete nightmare for me. I could do it in theory, but not without

For the sake of completeness, cos is the x value, because of the identity sin(x)^2 + cos(x)^2 = 1. You should find a good unit circle trigonometry picture if your class isn't giving it to you. Wikipedia's picture is frightening ( http://en.

Wait...this sounded fantastic, but this isn't like a normal games console or even Steam. If OnLive folds or stops supporting older games, your console is worthless, right?
