Comment: Computing, Really? (Score 1) 420

by wrench turner (#41577419) Attached to: How Steve Jobs' Legacy Has Changed

I bank on every smart phone increasing the demand for a larger and more capable cloud, but the iPhone did not create cloud computing, the web did.

Being a computing professional for nigh on 30 years, I cringe when "computing" and "computer" are used interchangeably. It also bugs me when I hear claims that Computer Science is some lofty discipline that shadows over computer engineering and professional programming or someone corrects my pronunciation of GIF, or [/.pretence]

TFA: The Exchange of Features, Textures and Faces - The binding problem is a fundamental issue in neuroscience. The term refers to the fact that the brain processes color, motion, and other visual features separately and in parallel, yet our perception is of a unified world, populated by coherent objects.

I've long marvelled that as I'm speeding down the freeway, a black car followed by a white car in the oncoming lane looks like a police car: a black car with a white door.

Most OS's and programming languages will let you map your memory data structure to a contiguous disk file so your disk IO is performed at paging speeds. The file system is only touched when the file is mapped (opened). Your system can then be configured to chose to what degree your data is in memory vs. disk.

Instead of sorting datasets, use a testlist database (flat files). The test contains/links/points to its dataset. The test lists are selected at test run time. Each entry in a test list tells how to generate the specific test environment for the test. A test list entry contains the test, the RCS tag/version of the test to be "gotten", the test seed, and array of exit codes that should be retired, how many retries, whether the test is gating, and an array of tests dependencies. A test run can be considered to pass even though an individual, non-gating test fails. One test entry may extract and prepare the test data and other dependent entries can then run against that test dataset.

Running multiple services on one OS requires that when you must reboot a server because of an OS bug or mis-configuration all of the services are brought down... Same if it crashes or hangs. As compelling as that is I've never used a hypervisor in 30 years on 10's of thousands of servers.

I do routinely use chroot jails on thousands of servers to isolate the application from the host OS. This way I do not need to re-qualify any tools when we implement an OS patch.

Comment: 1998 eclipse from MS Statendam (Score 1) 504

In 1998 my friend Bernie and I took a cruise on Holland America's MS Statendam to view the solar eclipse off the coast of Curacao. We planned to broadcast a live webcam over the internet. The ship radio charges would have been charged by the time that we kept the radio busy, not bandwidth or "connect" time. The Statendam radio man agreed to let us use the radio for free because it would have been very expensive. Twice we spent hours rehearsing, trying to call my dialup Netcom account, but I failed. We had radio problems, modem problems and ISP problems.

I understand that ham radio operators can probably lend you a lot of help. I guess you should get a license and get up to speed.

Be wary of your location when making a ship-to-shore internet connection. Some countries consider it a serious crime.

+ - Sun Releasing 8-Core Niagara 2 Processor

Submitted by Anonymous Coward
An anonymous reader writes "Sun Microsystems is set to announce its eight-core Niagara 2 processor next week. Each core supports eight threads, so the chip handles 64 simultaneous threads, making it the centerpiece of Sun's "Throughput Computing" effort. Along with having more cores than the quads from Intel and AMD, the Niagara 2 have dual, on-chip 10G Ethernet ports with crytopgraphic capability. Sun doesn't get much processor press, because the chips are used only in its own CoolThreads servers, but Niagara 2 will probably be the fastest processor out there when its released, other than perhaps the also little-known 4-GHz IBM Power 6."
