Comment makes me sick. (Score 1) 351

I was in college when my roommate told me about the coolest new game; it's like Wolfenstein but better. It being college, somebody kindly left some bootleg copies in the lab computers between the routine clean-up/reimage. I was initially uninterested, but eventually gave it a try. After one all-night session a few weeks later, I crawled out of the lab feeling somewhat ill. Ever since then, playing Doom makes me slightly nauseous. I don't have any problems with other games like Descent, but I'm sick of Doom forever. Maybe, 20-odd years later, the effect has worn off...

Comment Re: Snap Circuits disappointment (Score 1) 200

Ditto here. The wife got the grandparent to get it for the kids. It is a bit of a disappointment. I wish it at least had a couple of different resistor values, a few caps, and maybe a discrete transistor or two. In terms of documentation for the "IC" blocks, the manual did contain some description, and the PDF on their web site contains the internal circuit diagram (well, sort of. The inside of their custom ICs are still "black box".) I had one of these: https://en.wikipedia.org/wiki/... as a kid. It was wonderful. I wish my folks didn't get rid of it after I moved out. My brother had one o these http://cba.sakura.ne.jp/ex/mx1..., which I inherited after he moved on to bigger and better things. Both of those beat the pants off of snap circuits.

Comment Signing cameras (Score 1) 41

I don't know about identifying things after the fact, but an idea I've tossed around for a few years now is a forensic digital camera. Basically, the hardware will sign/watermark all the photos it takes with some sort of digital signature unique to the camera. The private key would be buried in silicon in such a way as to destroy it if attempts are made to discover it. I'm not a security/encryption expert by any means, so I don't know how feasible this is (or does it already exist?) but sounds plausible to me.

Comment Re:My worry is the credibility loss of visual reco (Score 1) 61

One of the ideas I've had for a long time is to make digital cameras that cryptographically sign every photo. Maybe such things already exist. I'm not expert enough on those matters to tell whether there are pitfalls in this idea. The key would have to be buried in the silicon somehow such that attempts to get at it would destroy it.

Comment Quadra with Dell power supply (Score 1) 258

I once fished a Quadra 630 out of a dumpster. It wouldn't power up. I fished out a Dell P3 low profile desktop out of the same dumpster. Its power supply fit the space of the old power supply pretty well. I was able to re-wire the ATX power connector to match the Quadra motherboard pinout. The tricky part is that the ATX power on signal is inverted sense from the Quadra. I found a hex CMOS inverter in a disused component shelf (no one used throughhole components any more) at work and soldered it in to use the stand-by power and invert the signal. The Quadra still works.

Comment You can upgrade your 2014 MBP (Score 4, Interesting) 204

According to this: http://blog.macsales.com/25878... OWC put a 4x PCIE SSD from a mac pro into a 2014 MBP and got the extra performance gain. i.e. the 2014 MBP has 4x PCIE wired to the connector, but by default ships with a 2x PCIE SSD. They expect to ship SSD upgrades for MBP "soon", so you're not out of luck if you have the previous model.

Comment Re:Units! (Score 1) 176

In Japan, they use the number of inches, but stick a placeholder word "gata" ("shape" or "format") rather than "inch" to the end. I read that this is because inch is not a legal unit of measure (Japan is metric) so they're not allowed to use it in advertising. So 42" TV is 42-gata TV. I don't think I've seen the cm measurement other than in the "detailed specs" of a product.

Comment Re:SED? - LEEPROM (Score 1) 239

One of my classmates in microprocessor lab back in college managed to make a LEEPROM. For those too young to remember, EPROMS have a window on them into which one shines UV light to erase it before reprogramming. With enough voltage between Vcc and Ground, the same EPROM can be made to emit light. Hence, LEEPROM. It was quite amusing at the time....
