Have onsite backup behind it's own firewall, accessible through a separate network interface AND offsite backup. Recovery time using the onsite backup will be much faster, and you'll have additional redundancy.
Why were your backup servers accessible from the outside network? Your backup servers are arguably even more valuable than your production servers. They should be behind yet another firewall. You can even have the production servers connect to them through a separate network interface. (Network interfaces and Cat5 cables are cheap.) If you are really paranoid, you can create folders where the server can upload data, but can't erase or overwrite what it has uploaded.
Implicit in your argument is the assertion that the Mind is deterministic. We actually don't know enough about our minds or the brain to know if this is the case. We have very strong reasons to believe that our mind follows deterministic natural laws, but we cannot completely eliminate the other possibility.
Why not just use Amazon Honor System to give money directly to Joss Whedon and/or Ron Moore, and distribute the show weekly with a private Bittorrent tracker? Heck, why not just make a season a shareware app? What's a reasonable price for a season? $20? All you need is 100,000+ viewers a season, and this thing would work economically. (Heck, I'd even live with B5 level special effects if we could have a new series with intelligent writing and Morena Baccarin, Summer Glau, Nathan Fillion, Tricia Helfer...)
There are still non-performers at Apple. MobileMe is screwing the pooch and has been since the dot-mac days. Also, who the hell are the bozos vetting iPhone apps?
A far as Steve's Health goes, economists and epidemiologists can predict when you are going to die with something like an 85% certainty. Basically, almost everyone experiences a 7X increase in health care costs, and then is dead in two years. Things don't look so good for Steve. This is too bad, because he's done a lot for the computing world.
This only works for certain cases. Some your problems are too many orders of magnitude too big to throw hardware at them.
Before you do anything: Profile, analyze, understand.
It might be useless to spend a month of development effort on a problem that you can solve by upgrading the hardware. It's also useless to spend the money on new hardware and the administrator time setting it up and migrating programs and data, when you could've just known that wouldn't have helped in the first place.
Two questions I used to ask when giving talks: "Okay, who here has used a profiler? [hands go up] Now who has never been surprised by the results? [almost no hands]"
Before you spend money or expend effort, just take some easy steps to make sure you're not wasting it. Common sense.
People don't realize that you don't need to *replace* yesterday's technology to succeed. There's still tons of COBOL running out there. Java, Python, Ruby do not act as *replacements*. They are layers of something new and different. If you replace something obsolete, you're just slotting yourself into a role that makes you obsolete!
Stevens's speech was analyzed by Princeton computer science professor Edward Felten, who said that he disagreed with Stevens's argument but felt that the language "series of tubes" was entirely reasonable as a non-technical explanation given off-the-cuff in a meeting.[12]
The term pipe is a commonly used idiom to refer to a data connection, with pipe diameter being analogous to bandwidth or throughput.[13] For instance, high-bandwidth connections are often referred to as "fat pipes."
Most routers use a data structure called a queue to buffer packets.[14] When packets arrive more quickly than can be forwarded, the router will hold the packets in a queue until they can be sent on to the next router or be dropped.[15] On links that become congested, packets typically spend more time in the queue than they do actually moving down wires or optical fiber...
I too disagree with Steven's argument. But people who jump on "tubes" often do not even know the concepts behind the analogy. In a lot of cases, the people that laugh at his comment are even less informed about the topic than Stevens.
If NAND flash SSD lifetimes are determined by write frequency, then wouldn't this be fantastic for archival storage? Just write the data once, then read it as many times as you like.
When SSDs get to the mid-range price they start to look good for archival storage. The lifetime of NAND flash SSD is primarily determined by the number of writes, so they should be great for this purpose.
Astrobiology doesn't do it for me. The LHC rap had a sense of fun, was well constructed, managed to have a high density of content, and didn't take itself too seriously.
I appreciate Jonathan's effort and his very cool video editing, but it suffers from following an act like LHC.

If you sacrifice the bed, you can get a 92 mile range commuter vehicle out of an old S10.
That may be much more than what you need, but the less you draw down your batteries, the longer your batteries will last. If you never let your batteries drain below 95%, they will last much, much longer than if you're draining them halfway down every day. In the long run, this may save you a lot of money, as battery replacement is the majority of the cost per mile for running an electric vehicle.
Open Source is now used as a weapon in corporate competition.
Why does IBM spend money to release Eclipse? To hurt Sun. (What does an Eclipse do to a Sun?) To make it more difficult for Sun to earn money off of Java. (You can commoditize something to prevent it from becoming your rival's money making product.) At the same time, the software is an economic complement to things that IBM sells. (All manner of middleware and corporate consulting, mostly the latter. A great IDE and other tools encourages more in-house corporate development. More opportunity to sell stuff like consulting and middleware.)
It would be different, because instead of replacing the whole drive, you'd just swap out a little card. This would enable RAID5 in smaller form factors, which would mean more reliable laptops and potential space savings in data centers.
Xubuntu is a great environment based of XFCE. I use it. It even runs well on QEMU on a simulated Pentium II.
HaikuOS, which was inspired by BeOS, looks quite impressive. The footprint of the full distro is under 100 Meg, and it's very finely architected for responsiveness.
On a "News for Nerds" site, moderators should understand the sources of disk latency. Rotating Hard Drives have latency from the time it takes to move the head across the platter, and for the platter to rotate under the head. SSDs do not have these sources of latency.
One of the big problems is that current flash is just slow on writes. Some of them don't do DMA properly. If there are problems with block sizes, this can be adjusted easily. But the underlying technology has to improve, or manufacturers need to build SSDs with more parallelism and better features. Perhaps very parallel SSD architectures might need filesystems optimized for large block sizes.
One of the big potential benefits of flash is reliability. Imagine highly modular flash drives for servers with hardware RAID 5? Instead of a disk failure, you get a notification that a module needs replacing. In fact, you could build versions with an extra slot for a failover spare in-place!
Also, with wear leveling, there's the potential for hard drives that can warn you several days before they fail!
