Compiling cpuminer on a RaspberryPi

I just spent the last bit compiling cpuminer on the RaspberryPi, and here’s my notes:

  1. sudo apt-get install automake libcurl4-openssl-dev libssl-dev
  2. ./configure
  3. Edit the compat/jansson/makefile and switch ar and ranlib to gcc-ar and gcc-ranlib
  4. make
  5. strip cpuminer


Blue laser pointers

When did blue laser pointers get so cheap? Right now you can get a blue laser pointer from Amazon for less than $8 (link).

I’m not sure these are legit, but the one I have (from Yugster) looks the same and works OK. It has a pretty wide beam compared to my green pointer, but it’s still very cool. Oddly, the blue pointer is the only one that seems to excite the glow-in-the-dark stars on the kids’ ceiling.

Does anyone know why some of these pointers are selling for $150 (link), and others are selling for much less?

PS: I should also note that this thing is much more powerful than its <5mW rating. It’s probably closer to 30mW. It’s definitely not a toy, and I’m pretty sure I shouldn’t let the girls play with it.

Hey, I won something!

You know those Internet sweepstakes that just about every website seems to host. The ones that end up getting you spam every couple of days, and that no one seems to win. I won one of them.

OK, it was the Esquire Augmented Reality give-away, and I only won one of the fifty webcams (Blue Microphones Eyeball 2.0), but it was a nice surprise to receive it in the mail. They were suppose to notify me back in January, but I never heard a word; it just arrived.

As far as getting spam, that particular contest didn’t increase my incidence of spam. Probably because at the time I was actually a subscriber to the print edition of Esquire. I do wonder if it helped my chances though…
