Comment Re:Why 18 months? (Score 4, Insightful) 155

The tinfoil hat in me fully expects them to use this to kill the used phone market, jail breaking, and any number of other things that are consumer-unfriendly. "Oh, you lost your phone and don't qualify for a new free one yet? Sorry, you can't buy a used one from your bud. You have to buy a new one from VZW/ATT/etc." This is a solution rife with problems for the consumer.

Comment Primaries in NH (Score 1) 228

It's Presidential Primary Season here in New Hampshire, so we get at least one call per day, and those are exempt from the Do Not Call list. Sometimes it's a recording of the candidate. Sometimes it's a supporter of one of the candidates. Sometimes it's a pollster. A lot of the time it's a supporter of a candidate posing as a pollster. Those are easy to tell because the questions are leading.

I've got one of these on my desk as I write. I've actually been working with it for several months now, and it's pretty sweet. It's intended to be a DSP co-processor coupled to an FPGA. The company I work for (BittWare) has invested heavily in Adapteva, and we are introducing some boards featuring a handful of 16-core Epiphany chips (which we have rebranded as "Anemone") and an Altera Stratix 5 FPGA.

The tools are Linux-only at this point, but that's more than OK by me. I think this is the first time I've ever not been forced to use Windows to develop code for a new processor.

The target application is anything that requires lots of DSP but can't burn many watts.

Submission + - DHS Admits Knowledge Of Infected Technology (fastcompany.com)

smitty777 writes: Deputy Undersecretary Schaffer of the DHS National Protection and Programs Directorate confessed to being aware of foreign technology that had been imported with spyware, malware, and other security risks. According to the article, "More worryingly, the hearing specifically mentioned hardware components as possibly being compromised--which raises the questions of whether, perhaps, something as innocuous as Flash memory or embedded RFID chips could be used by interested foreign parties."

These hearings were held on July 7th to "examine the nature and extent of the current threat to America's infrastructure.

Submission + - Comet-sun impact caught on video (nasa.gov)

jomegat writes: "NASA has released footage captured by the Solar Dynamics Observatory (SDO) showing a comet slamming into the surface of the sun. The impact created a huge splash as seen on the video, but the impact at the surface was blocked by an occluding disk that allows the SDO to image the sun's corona. It's still very impressive though!"

Comment Re:I would love to make the conversion (Score 1) 468

I would like to put some PV cells on the roof, but it really bugs me that even though they produce DC (which I need), I'd have to convert it to AC, deliver it to my equipment, and then convert back to DC again inside the device's power supply. These cascaded conversions take their toll - if 80% each, I have a total conversion efficiency of only 64%. Ouch. That really hurts if you're trying to squeeze all you can out of a PV setup.

I thought of a possibly viable path the industry could offer for converting to DC. What if a computer manufacturer started offering desktop machines with an UPS integrated into the power supply? The marketing reasons for this are somewhat compelling - it makes the desktop behave more like a laptop. No need for a separate UPS, etc.

They could at the same time take the further step of providing UPS-backed DC outlets on the PS itself, and then sell other equipment that would plug into these DC outlets - routers, cable modems, printers, monitors, etc. One advantage gained by the manufacturer here is that they would no longer need to provide region-specific wall-warts for small equipment.

Alternatively, a manufacturer could make an UPS with DC outlets as well, so this wouldn't be limited to desktop systems. Third parties would spring up to provide cables to connect the router you already have to this DC outlet in place of the wall-wart. Why buy a $60 router when you could get the same effect for a $5.00 replacement cable?

Once those devices become widely deployed, it's a short jump to DC outlets in the walls. Once that happens, the desktop no longer needs an UPS-backed AC supply - it could just have a DC cable like all the other gear. From there it's a short hop to in-home, battery-backed, off-grid (or aux-grid) power, be it PV or wind, or whatever. Then my innernets would stay up even when an ice storm takes out the grid.
