This had me up far too late yesterday trying to figure out WTF is going on.
Here's the condensed version: * Pings work fine, other websites work fine - only HTTP to google.com with a "google.com" host header is affected * HTTP 1.0 without host header isn't affected * Going to one of google's web servers by IP works fine (no "google.com" host header) * I am typically seeding torrents and was at the time of each service interruption * TCP RSTs follow a specific pattern. 2 RSTs in rapid succession in response to the initial GET statement (1 with a valid SEQ, one with a SEQ in the 12xxx range), followed by a second batch of the same. As the article here states (and as I posted in the linked thread), this matches perfectly with results from the China firewall * The problem went away at almost exactly 12:00am EDT this morning (give or take a minute) * This is from a Comcast subscriber in Grand Rapids, MI.
For more detail, visit the thread linked. I have links to the raw packet capture data in.pcap format if you'd like to take a look.
I had a 1.5/384 line from Speakeasy until August of last year with 5 statics for $110. As a reference, I now have 8m/768k from Comcast for $70. Early last year (spring time roughly), I received a series of emails and phone calls from Speakeasy regarding my bandwidth utilization (specifically usenet and torrents). I was told originally that they were worried that I might be infected with a spam zombie or some such. After I had assured the representative that this was in fact not the case, I was eventually able to wrangle out of him that he was basically calling me to try to get me to stop using so much damn bandwidth, but that they wouldn't cancel my account unless I received any notices from copyright holders.
So yeah, even Speakeasy (pre-buyout) would hassle you for bandwidth, they wouldn't come right out and say why, but they wouldn't cancel your line and would tell you why they were really calling if you asked them directly.
The technology you are talking about is called free-space optical and is fairly mature. For the distances you are shooting, you should be able to run gigabit reliably. They are relatively secure, but you'd still want to run some sort of VPN over the link (at gigabit speeds this may be difficult). For shorter distances (such as those listed), you will find they are plenty reliable and can handle even heavy rain if installed correctly.
From the FAQ, the expected lifetime of these displays is 5000 hours. That's a little over 200 days. Even with a "key saver", this severly impacts the usable lifetime of this device. I'm as excited about this keyboard as anybody else, but I think I may have to wait until people have had one on their desk for a year to see if I'm going to plunk down a significant amount of coin to buy one.
Your car does that on a gallon of gasoline, not hydrogen. It still isn't at the energy density level of gas, but it's getting close. Oh and 0 emmisions, which we're pretty sure your sports car doesn't do.
The price of the components has certainly come down, and if you open up a recent (version 1.6) xbox and compare it to an earlier version, you'll find that they have greatly streamlined the number of discreet components inside.
However, the xbox originally sold for $399 and now retails for $150. Who knows if they're still loosing money on these, but I'd guess they still are subsidizing the software/online business by taking a loss on the hardware.
The Rainbow Series was a series of books published by the government on developing and deploying secure computing platforms in the late 80s, in conjunction with the DoD and MITRE. It's now largely dated, but there's still some good theory to be found. It's also freakin huge, and would take years to read them all.
Unfortunately this is incorrect. It may sound like surround sound, it may even be Pro Logic (which is an analog hack to get surround sound out of a 2 channel source), but nVidia holds the only license Dolby ever sold for realtime Dolby Digital 5.1 encoding hardware. If you don't have an nForce-based motherboard, you aren't doing real Dolby Digital 5.1 through SPDIF.
Canon already offers a system for this very purpose: http://www.dpreview.com/news/0401/04012903canondvk e2.asp
Of course, the feature here is that it can be turned on or off as the user wishes. Moreover, you don't need to encrypt a file format to create a valid digital signature for it.
The only reason for Nikon to do this is to make sure that they can charge a license fee for anyone who wants to be able to manipulate raw images taken with their hardware. The best solution for everybody would be to do the obvious thing: buy a Canon:)
the fifth interpretation isn't too far off. take for example the phrase "fruit flies like a banana". just by changing a couple nouns the 5th interpretation becomes the correct one.
as soon as someone makes a parser that can correctly differentiate between the two i think we'll have seen some real development in natural language parsing.

after wading through a couple dozen posts of hopelessly useless pedantic crap, i figured i'd offer a reasonable suggestion: check out the colorvisionspyder 2 calibration tool. it's relatively inexpensive, supports windows and mac, and is widely used throughout the industry for photo manipulation and graphic design workstations. combine with a print scanner, and you can get full start-to-finish calibration of your workflow process. here's a review of the previous model.
as some others have noted you can plan on recalibrating at least once a month, particularly with new monitors. if color accuracy is less important than precision (that is, it doesn't matter if the color is correct as long as it looks the same everywhere), make sure you are using the same model of monitor on each desktop as each phosphor combination used in a given model of tube produces a different color gamut. in all events, stay away from lcd - the gamut is crap and they don't hold calibration well.
easy - use shared storage. hell, use an nfs mount if you like. use a common db back-end, and have the server software failover to another db if the first fails. this is clustering for front-end software, not back-end - the back-end is easy. getting a web browser to play along with a clustered front-end is a little more trickey.
you would have to send video like you would any normal hdtv or vga signal - there is no digital video output on the xbox. audio authority makes very well reviewed long-haul extenders for both formats.
The XBox isn't completely silent, but you can control the fan speed through software. Much of the noise is mediated if you replace the default 8GB HDD with a larger 5400rpm (slow and quiet) drive. Modding a newer unit (version 1.6) requires the installation of a modchip or using a softmod. Softmods don't require any soldering, but are prone to occasional failure as MS updates the XBox software. Your best bet is to troll your local pawn shops and video game stores for a used xbox. If you can get a 1.0 or a 1.1 version XBox you can mod it complete with a disable switch without having to buy a chip. Anyway, the point of all this is to run XBMC, which will play damn near any media format you can through at it, including newer container formats like OGM and Matroska. It can stream over the network using SMB/CIFS or one of a handful of XBMC-specific streaming protocols (stream servers available for linux, mac, and windows.) XBMC can also display local weather, stream web radio from shoutcast stations, rip cds, play dvds, display rss feeds, and with the python script engine it can even play movie trailers or even give you showtimes for movie theaters in your area.
Being a cheapass, I use cheap modchips. You can get an Aladdin XT for $11 from RobotPig. They're in the UK but they ship quickly worldwide. Good shop and cheap! The $60 modchips come with loads of neat but ultimately entirely useless features.
If you're scared of a soldering iron, here's a solderless solution for all versions of the xbox: The Spiderchip. I've never used one of these things and I've never purchased anything from this shop so take this as a suggestion and not a recommendation.
Here's a great introduction to softmods. Again, despite what all the softmoddie guys say a chip will always be a better solution.
If you buy a new XBox, you'll be getting a 1.6 version and your modding options are somewhat limited. You're voiding the warranty anyway so you might as well pick up a used box. Here's how to tell which version XBox you're getting. Print it out and take it to the shop with you.
All versions of the XBox except the 1.6 can be TSOP flashed, which is just write enabling the onboard BIOS flashrom and flashing a mod bios to it. Cheap, relatively easy, and every bit as good as a chip. The only drawback to a TSOP flash is that you can't easily disable it unless you have a 1.0 or 1.1 XBox. Here is a pretty complete guide to TSOP flashing.
Here is the homepage for XBMC. They're hosted on sourceforge, so you can checkout the CVS and compile your own copy if you have VS.NET 2003 and a copy of the latest XDK.
Check out the forums on XBox-Scene and for XBox Media Center (XBMC) for useful tips rom the thousands of XBox enthuiasts out there. Good luck!
The study comes from CacheLogic (http://www.cachelogic.com), which sells bandwidth throttling appliances to ISPs, schools, companies, etc. Considering that their business is to scare large-scale internet users into throttling the bandwidth use of your typical BT user, I don't find it at all surprising that they are claiming somewhat inflated numbers for P2P use on the internet at large.
it looks like it only sends the "toggle" commands, not just the discreet "off" command (which most modern sets support), which would also let you turn on sets too.

I'm not sure where you are buying DSL, but the datacoms world has been using 1k == 1000 for decades now, long before storage vendors caught onto it.

You can get info on emulators for the 2600 and about 30 other retro systems on the xbox here.
