Computer Monitor In Eyeglasses

Except your eye naturally "shifts" position every few milliseconds I believe. It's a way for you to continually see since your eyes tend to "disappear" anything that is completely motionless.

Full DMA access for USB-OTG on PPC405EX

hcob$ hcob$ writes  |  more than 5 years ago

hcob$ writes "I'm doing some early prototying of a AMCC PPC405EX based board. Here's just a few of my actions so far to let you know how much frustration this one little problem has casued me:

        * Fixed the broken OpenWRT support for the AMCC Kilauea Dev Board with patches, backports and Makefile Modification
        * Ported DENX deployed USB-OTG support with the dwc_otg driver
        * Reworked the flash map so that there is a custom fall-back ramdisk and a fully-permenant rootfs

Then comes the next problem. After finally porting in the dwc_otg USB driver to the OpenWRT patched kernel, I went about hooking up some usb-serial devices that we planned to use. They detected properly and registered. The I open up a minicom connection and WAM! 99-100% IRQ usage. Completely bogged down the system. Turns out, the device is running in an IRQ(Slave) mode and triggering interrupts that need to be serviced at an insane rate (had a back log of 89k interrupts at some points). After two weeks of focusing on this problem, I finally noticed something odd in my kernel build."

November is a time to celebrate figs. November marks the end of the fig harvest in many locals. Figs are good for you. High fiber and high nutritional value . . . fat-free, sodium-free, cholesterol-free . . . not to mention the great taste.And they are portable.Figs are an often overlooked fruit. (Dull men can identify with being overlooked.) California has a great web site about figs . . . a site that doesn't overlook figs: http://www.californiafigs.com/index.html. It as a History of Figs. Oodles of fig recipes. Dull men in California's San Joaquin Valley have a fun activity . . . they like to watch figs dry.

hcob$ (766699) writes "Fox News is reporting about new research for an alternative explanation to Global Warming.

For those of you that don't want the op-ed piece from Fox News, the Actual Paper Here Ten years ago, Danish researchers Henrik Svensmark and Eigil Friis-Christensen first hypothesized that cosmic rays from space influence the Earth's climate by effecting cloud formation in the lower atmosphere. Their hypothesis was based on a strong correlation between levels of cosmic radiation and cloud cover — that is, the greater the cosmic radiation, the greater the cloud cover. Clouds cool the Earth's climate by reflecting about 20 percent of incoming solar radiation back into space.

The hypothesis was potentially significant because during the 20th century, the influx of cosmic rays was reduced by a doubling of the sun's magnetic field which shields the Earth from cosmic rays. According to the hypothesis, then, less cosmic radiation would mean less cloud formation and, ultimately, warmer temperatures — precisely what was observed during the 20th century.

Just last week, Svensmark and other researchers from the Centre for Sun-Climate Research at the Danish National Space Centre published a paper in the Proceedings of the Royal Society A — the mathematical, physical sciences and engineering journal of the venerable Royal Society of London — announcing that they had experimentally verified the physical mechanism by which cosmic rays affect cloud cover.

In the experiment, cosmic radiation was passed through a large reaction chamber containing a mixture of lower atmospheric gases at realistic concentrations that was exposed to ultraviolet radiation from lamps that mimic the action of the sun's rays. Instruments traced the chemical action of the penetrating cosmic rays in the reaction chamber."

hcob$ (766699) writes "It appears that Chase has accidentially thrown away personal data of some 2.6 million customers. According to the article:

Chase Card Services said it mistakenly tossed out computer tapes with the personal information of Circuit City card holders. It said it believes the tapes, inside a locked box, were compacted, destroyed and buried in a landfill.
Hey, if your data is going to be acciendtially thrown away, there could be worse ways. Although, this also begs the question, "Who in their right mind would think a locked strongbox is trash?""
