## Comment Re:Why not multiple dogs? (Score 3, Informative)97

That theory doesn't hold if all 10 dogs are missing the same 20% due to a common failure mode.

That's not necessarily true either. A scheduling analysis could be performed to determine the real-time capabilities of the system. A simple stability program running on a massively overpowered linux system could be proven to guarantee scheduling at a low update rate. It's just not an efficient real-time system.

## Comment Loose change (Score 5, Interesting)339

In the bitcoin equivalent of losing loose change in your couch, one of my old hard drives has 4 mined bitcoins on it somewhere. They are rapildly approaching a value high enough for me to stop being lazy and ressurect the machine.

This is especially true for pre-1996 pennies, which are 98% copper. roughly 3-4 cents per penny depending on the current copper price.

## Submission + - Rare operating Apple 1 rakes in \$374,500 at Sotheby's auction->

coondoggie writes: "It's not one of a kind but pretty darn close. Sotheby's this week auctioned off a rare working Apple 1 computer for \$374,500 to an unnamed bidder. The price was more than double the expected price listed on the Sotheby's web site.
The Sotheby's notes about the Apple 1 say it is one of six thought to be operational boxes and one of about 50 known to exist."

For Natural Gas (@0degC)
Specific Heating = 47.7MJ/kg
gas density = 0.72 kg/m^3
cost ~= 0.25 \$/m^3 (typical Ontario with distribution)
efficiency = 50%

= 4.77 kWh/m^3
= \$0.052 / kWh

this would assume it could run on natural gas, but it needs pure methane. Even so, it ends up cheaper than grid electricity.

## Comment Re:No alarm clock here (Score 2)197

That only works if your body's natural clock is fairly close to 24h and your rhythm can sync in with the clock. I think average is around 24.5h. I'm in around the 25h mark. I can sync with 24h for a few days, but if I leave it natural I'll add an hour every day (vacation or on flex time).

## Comment Cheap Source of Copper (Score 1)473

Pre-1996 Canadian pennies are 99% copper. Last I checked, the ones I'm saving (hoarding?) are worth 3.6c each.

## Comment Laser Failure Mode (Score 2)224

The good news is that if the laser fails, the data should still be available to read and copy onto a new hard drive. If the laser was needed for reading as well, I'd be wary of the reliability.

## Comment Get a good adapter set (Score 3, Informative)165

I've used a GQ-4X Willem Programmer with good success. The trick is to get a good set of adapters, so you have the flexibility to cover many packages. PSOP, TSOP, etc. I've even found one that lets me do a serial SOIP8 EEPROM while it is still on the board-- very handy to not need the remove&resolder.

Somebody ought to cross ball point pens with coat hangers so that the pens will multiply instead of disappear.
