A few exploratory questions: * What is the nature of the electronic device? A PCB? A chip? One or several PCBs integrated with a case, batteries, buttons, etc (i.e. a finished end product or prototype of one)? * Do you need to ou

Sorry about that, it didn't register that GP's question was tangential to GGP's UWB-focused links. Regarding IR, I agree that interference is the biggest issue. The electronics also get harder as you approach THz frequencies, but that cou

A small nit: proposed UWB (ultra wide band) schemes at 5GHz and 60GHz are considered EHF (extremely high frequency) or millimeter-wave; IR is generally considered to start at at least 300GHz. There isn't a heck of a lot of interference per

There are a couple linear-time selection algorithms, some randomized and some not. An example of the latter is described here ( http://www.ics.uci.edu/~eppstein/161/960130.html ). The constant factor is non-trivial here (<= 24n comp

In general, this will probably get you close to maximum performance. Most CPUs implement shift, rotate, AND, OR, XOR, and NOT instructions, and usually not much else in the way of bit manipulation (besides maybe a few very specialized intr

For some, 15 days is exactly 3 work weeks.

Agreed, there are analogs to everything mentioned here that are applicable to {hardware,software} engineering teams as well. One gem: In order for highly hierarchical organizations to be effective, they require one person who understands

What about one with the binding up top?

That came off as more petulant than I would have liked. My apologies.

"David Bello Let's...?" Right in the title? Seriously?

I think his point is that not everybody can set their own hours that way.

1.0e5 is a lot more interesting than 1.0e2 :P

It's impressive that they were able to beat 2009Q1 even by using LLVM naively. Looks like their first few releases are the software analog of Intel's tick-tock strategy ( http://en.wikipedia.org/wiki/Intel_Tick-Tock ), and it looks like we

True, but there is still a namespace conflict within the security world. Google's Native Client ( http://code.google.com/p/nativeclient/ ) is called NaCl by the developers, and more and more externally as well :P

is it an artifact of my machine or is that video really hard to hear?

I have a couple. They're good for hooking a laptop up to a TV from across the living room, or hooking up a game console to a monitor on your desk when you don't want the console anywhere near your desk. Of course, I buy the $12 monoprice v

Rigel ( https://rigel.crhc.illinois.edu/ ) is one such project, though the silicon implementation is decidedly less far-along than AsAp. The goal there is 1024+ cores in 45nm. The targeted applications are more like "things that are massi
