Well, here the only cable modem provider that is available in my area is Time Warner's Road Runner service. Ever since I moved to my new residence, the service has been horrible. I have seen latencies of >4000ms in the evenings, with some timeouts as well. My wife plays an MMORPG, because of this and packet-loss (stand back! I've got traceroute and I know how to use it!) she sees 16 - 30 second delays during game play. I've seen downloads (my house friends house, 200 feet apart) range in speeds from 30kb/sec at the best (we have upload rate restrictions) to 30bytes/sec.
Cable modem is horrible once you get enough subscribers hooked up to the system (IMOE, in my own experience.) Even more outrageous, we were told this area was only at 60% capacity. Heavens help us when it reaches 90%.
Lastly, RR does *not* offer static IP's because they do not want people running servers. RR also runs weekly scans of their network, to catch the poeple who run servers and boot them from the network.
So tell me why I shouldn't want DSL service from someone like Speakeasy who doesn't care if I run servers and will even give me SLA with a specified CIR?
Write your Senators and Representatives, people. Call them. Fax them. Remember, they work FOR YOU. Not the other way around. Tell them not to support HR46.
Your last two sentences are misspoken. We have been neglecting the entire philosophy that the country was founded on. Go back and examine government history, about the bills that were proposed and those that became laws, especially in the early 1800's. You would be suprised -- for example, James Madison vetoed a public road act that Congress had passed. Madison gave his reason as: Congress does not have the authority to authorize funding for improving public roads according to the constitution. What do we have today? Congress enacting a law that states, "States will set their BAC level's to 0.08 for DWI laws or lose the money for roads and highways that comes from the federal government's coffers (our pockets)." Our country was not founded to have a very powerful strong central (federal) government. Read the constitution and the federalist papers, as well as many of the early supreme court decisions, laws, and bills introduced into Congress. You'll be suprised and enlightened.
Our founding fathers were very wise/intelligent men. They recognized that the gravest danger to any free society was it's own government. Their design was for a mostly static government unable to accomplish much, with the real spending and taxation done at the state government level.

Actually - RAID5 can slow things down (even hardware), especially for databases. Check with your database software vendor for recommended settings. You are much better off wasting the disk space and using mirroring or mirroring and striping (which we do for ~100GB databases.)
I highly recommend using raw space for your database - it helps the performance of your machine greatly. Also, it will avoid caching the data twice, which is a waste of memory that could be put to better use.
Keep your raw spaces small, 512m - 1g should be your max depending on your disk size. Find out which tables are the most heavily hit (both read and write, but most especially writes) and spread them out among several disks.
If you can, make use of a volume manager.. it especially helps manage the 100's of small spaces...
Where I work, we use software RAID on the UNIX boxes (Level 3 database servers supporting at least 10,000 users) exclusively. On the NT servers, we're using hardware RAID exclusively.
Basically, what it boils down to is what are you using the server for? For some things, hardware raid just gets in the way (e.g. large database servers), and on others software raid just sucks down the CPU cycles and bus bandwidth needlessly, or is too dangerous (e.g. Windows NT).
Someone please moderate this post up. This is the perfect analogy for the CSS/DeCSS fiasco. Maybe the defendants in the DMCA trial can utilize this for a defense... Anyone notice that DMCA is the acronym for 'Always Control Media (or movie, music, etc) Distribution' in reverse?;-)
One of my biggest complaints with the current moderation system is the fact that most of the time I'll see a single post that comes at the end of a thread, which 95% of the time is completely meaningless without reading the rest of the thread.
With that complaint off my chest, I'd like to suggest that we could move the A.C. posts to the end of the page (or perhaps a separate page). Any non-anonymous replies to A.C. posts would appear below the appropriate post (exactly like the current threaded view.)
Alternatively, we could simply have "two"/.s. One allows A.C. postings, the other does not.
Here's an example of why the GPL and BSD are not "compatible" (please note that both are "Open Source"):
BSD source code can be taken by anyone and used in a commercial product. The commercial product may be "Closed" or non-free software. All the "manufacturer" of the proprietary, commercial code has to do is acknowledge that his product is based off of code that was BSD licensed. This would be 100% legal (and fair) according to the terms in the BSD License (This is called "forking").
GPL source code on the other hand cannot be used in a commercial product unless the entire product is also GPL'd (note commercial != proprietary). The GPL thus prevents forking by someone other than the copyright owner (no license can prevent that.) This attribute of the GPL has also been called "viral." I've even some call the GPL non-free because it restricts the freedom of the developer/authors.
It really doesn't matter, because people will use the license they want to use and won't use anything else. Licenses in the "free" software world are a lot like editors -- everyone has their favorite and they defend them like religions.;-)
Off-topic. Uhm, you have that reversed. The Greeks built the large wooden horse and "left" it at the gates of the city Troy, hence the name the "Trojan horse." The unusual (at that time) and underhanded ploy won the war for the Greeks.

Just my two cents worth,

That is still illegal according to the laws/regulations of the US Government. There as a Ask Slashdot that covered this a while back Using SSH on non-US sites for Crypto Development.
