Exactly what I was thinking. I want the "gargoyle" like glasses from Stephenson's (and others) sci fi. Augmented Reality that visually appears like in the TED video, but is instead projected on the inside of the glasses or onto my eyeballs directly. A few high-quality cameras could map the 3D space so the projection could "wrap around the paper towels" or simply hover above it.
Especially in this case! The poor sysadmin might be investigating this strange executable, and decides to run ldd against it to learn more about it. (Hopefully she doesn't do this as root.)
X10 has had 3rd party open-source / linux support for years. The main problem with the tech is the combination of weak RF wireless and powerline communication. Modern circuit breakers (at least mine does) filter out the powerline communication between circuits. So when you're trying to control the lights across the house from your PC, the RF is too weak to make it there and powerline comm doesn't make it either.
X10 is nice in that the modules can replace wall sockets, light switches, light sockets, etc. so you can add to your house over time and you don't need much special wiring.
What about this clause that is attached to the GPL in the MySQL code?
This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
Yeah, apparently as long as [some of?] the source remains GPL, RMS seems okay with dual licensing.
Stallman's quote:
This approach was able to provide (1) an attractive platform for developers looking to use FLOSS, and secured MySQL enormous mind share, particularly in supporting content rich web pages and other Internet applications, and (2) the ability for paying clientèle to combine and distribute MySQL in customizations that they do not want to make available to the public as free/libre software under the GPL. With excellent management and considerable trust within the user community, MySQL became the gold standard for web based FLOSS database applications.
If you're using max CBR (constant bit rate), say 320k, it will sound better than a low quality VBR. But why not use VBR Quality 9? You'll hit the 320k+ ceiling when you need it, and save disk space when you don't need it (e.g. silence).
VBR (variable bit rate) is far superior to CBR (constant bit rate) for both file size and audio quality. The only reason to use CBR is to support ancient devices that cannot play VBR.
I use Grip to rip+encode, with Lame mp3 vbr-new as the encoder. (I like ogg, but I prefer a homogeneous audio-format library, so I'm stuck with mp3.)
Choose a VBR level that has an acceptable file size for you. For example, encode some CD audio at VBR-New Quality 7. Next, encode the same tracks as CBR 192k. Check the file size differences. Load them in your favorite player (e.g. audacious) and check the properties of the files -- the VBR one may show "189k" for track #1, "207k" for track #2 and so on. The CBR will always show "192k". (Note: the VBR sizes shown in the 'properties' window are just averages, any given "slice" of the song may be anywhere from 64k to 320k or whatever the floor and ceilings are of your encoder.)
Incorrect. Domain Tasting has pretty much been removed from the "game" by the new Add Grace Period rules which many registries, including verisign (com/net) adhere to.
Also, wholesale domain prices, set by the registries (again verisign here for.com, though they did reduce.net somewhat) have increased as well. Even.biz and.info have gone up, and those TLDs are relatively useless.
Or remove all partitions, and create one large partition that fills the disk. Then use TrueCrypt to create an encrypted partition. It will write to the entire disk. Works in most OSes. The really paranoid can choose a tripple cipher.
Agreed. Poor power kills CFLs, while "smooth" power, say from a dimmer switch, will treat incandescent bulbs nicely. I've had incandescent bulbs last over 10 years because they were only run from a dimmer.
Have you noticed that incandescent bulbs seem to die only when turning them on with a regular switch? It's pretty rare to see a bulb die while the swtich has been on for awhile and the bulb is warm.
Thanks for the reply. This is a single Xeon core2 quad, 2.6.24 (old, I know).
I have the following enabled:
SMP
NUMA
SCHED_MC
FAIR_GROUP_SCHED
(unsure which affinity is higher.. I can use 'taskset' on a process)
And the following disabled:
CONFIG_SCHED_SMT
And like others mentioned, a true quad-core with shared L2/L3 cache would negate this issue -- until you add another physical chip (total of 8 cores). Will the process be migrated between physical chips? Should it? Could it move "closer" (driver/bus/interrupt handling) to the device the process is interacting with (ram, eth, disk, gpu)?
My chip is a Xeon X5450, which is still two dual-cores in a single package.
Also,/sys/.../cpu*/cpufreq/scaling_governor is "ondemand". But the same behavior occurs if I turn off CPU scaling.
I thought it might be a "thermal feature" to keep all the cores balanced in temperature. And to examine this better, I should really use a heavy CPU process that uses low I/O, to make full use of the cache. Then possibly boot to a non-SMP kernel and time the differences to ensure the L2 cache moving is a factor.
Possibly... but it appears an SMP kernel treats each core as a separate physical processor.
Take an Intel Core2 Quad machine and start a process that takes 100% of one CPU. Then watch top/htop/gnome-system-monitor/etc where you can watch the process hop around all four cores. It makes sense that the process might hop between two cores -- the two that share L2 cache -- but all four cores doesn't make sense to me. Seems like the L2 cache is wasted when migrating between each core2 package.
Country Code TLDs (ccTLDs): .us.ca.uk.de.fr (etc, etc)
Arguably,.eu and.asia are ccTLDs as they are treated just like other ccTLDs, yet they do not match the ISO 3166-1 designation of 2 character country codes.
All gTLDs are completely unrestricted, while all sTLDs have some form of restriction as they are sponsored by some entity which regulates their use.
China's DNS supports their "Internet Keyword", known in the industry as a CN Keyword. It's the exact same concept as an AOL Keyword, you purchase the word/phrase without a TLD/extension and direct traffic to your website.

I wonder if the biggest "donor" (whoever purchased the most grades for the students) was awarded a Lobbying Certificate?

Sorry, I was looking at the mysql client code, not the server code. The client code has these FOSS exceptions:

I don't know if they've been in the default kernel for "a long time", but they are there now.

Better Top Level Domain (TLD) lists:
.com .net .org .biz .info .name
.mil .gov
.edu .int .arpa .pro .aero .coop .museum .eu .cat .asia .jobs .mobi .travel .tel
.us .ca .uk .de .fr (etc, etc)
.eu and .asia are ccTLDs as they are treated just like other ccTLDs, yet they do not match the ISO 3166-1 designation of 2 character country codes.
Unrestricted Generic TLDs (gTLDs):
Restricted US-only sTLDs:
Restricted / Sponsored TLDs (sTLDs):
Country Code TLDs (ccTLDs):
Arguably,
All gTLDs are completely unrestricted, while all sTLDs have some form of restriction as they are sponsored by some entity which regulates their use.
Almost all ccTLDs are restricted in some way.
China's DNS supports their "Internet Keyword", known in the industry as a CN Keyword. It's the exact same concept as an AOL Keyword, you purchase the word/phrase without a TLD/extension and direct traffic to your website.
In addition to Tokelau (.tk), don't forget about the other sellout, Cameroon. Go to any DNS-valid string + .cm. (e.g. 234lihs3-w3l4k.cm)
Wildcard TLDs are almost as scary as VeriSign wildcarding .com/.net or even the roots!
