At the simplest level yes, but cassandra (for example) is more like a multi-dimensional hashmap. Eg; Key-Value where Value points to another Key-Value and so on, so you can reference values such as:
SomeApp.Users[UserID][username]=bob
The advantage of this is being able to sort by time, alpha, etc, and therefore handle sorted pagination from the key/value listings.
The main advantage though is that you can literally just plug in more systems and have it scale horizontally without any extra work, unlike databases which need sharding, bigger machines, redevelopment, etc. once you hit the limits of basic clustering.
Poor artists, then they only have more people enjoying their works, allowing them to have bigger concerts, sell more merchandise, get paid more for tv and corporate appearances, income from product endorsements, etc.
Real demotivating.
Agreed, mini itx is one of the best ways to do this. Fanless has a long, stable lifespan and using a portable hard drive will keep operating power usage down close to a dedicated router so it does not work out that much more expensive. You can run a transparent proxy, secure remote access, transparent tunneling/VPNs, gather statistics, etc.
And the natural history museum is just up the road from the science museum - perhaps the most impressive museum building in the world, built to be a cathedral to science and full of dinosaurs, rocks (including meteorites), a cool earthquake simulator, large mammals, and more dead things in jars than you will ever see anywhere else in your life.
The Victoria and Albert museum is over the road from that too, and has a gigantic old persian rug (and I mean gigantic), and the very impressive cast courts that preserve many european statues and facades which were destroyed in the various conflicts since the victorian era.
You can buy them easily from the airport too (especially coming into the UK). Changing wifi settings is not needed - it is still 2.4ghz, the standard only changes the power levels. If it works in the US it will work in the UK.
For more geeky things, the welcome trust (featuring victorian medical curiosities like darwin's walking cane, a mummified south american, mad king george's hair, 19th century japanese sex toys, etc) and the british library treasures room (featuring the magna carta, gutenburg bible, domesday book, early maps, da vinci notes, shakespeare, beatles, etc) are great and are practically next door to each other. Most locals dont even know about them but they are definitely worth half a day or so between them.
This is at peak time, is a consistent speed and more often that not is limited by the server rather than the network from what I gather. Since any bulky transfers (offsite backup, log processing, etc) is all done early in the morning, that frequently hits 45Mbits. Still not squeezed out those last 5 though!
NTL were always bad. Blueyonder/telewest were good. Virgin got really, really bad about 2 years ago, but now things are improving to the point just after they took over blueyonder.
I've seen a SSD fail because the same sector - the superblock - was constantly overwritten to the point where it failed. Think how many times the superblock (if the relevant FS is using one) gets touched, then figure that in to reliability calculations too!
I currently have the 50mbit connection and finally, they have returned to their previous level of quality. I've managed to get 45Mbits out of it off peak, and consistently get 3.5MBytes/sec at peak times. I'm very happy right now, I have not even noticed the bandwidth constricting cap come in to play (which was a big problem on the 20Mbit/sec DOCSIS1)
I was going to recommend the exact same thing but you beat me to the punch. rdiff-backup is fantastic but would be truly indispensable if they would get rdiff-backupweb working properly!
in addition to this, some of the hotels have VPNs to Hong Kong so get around the firewall and are therefore a bit faster and mostly uncensored. Win/Win!
Well here's hoping they go one better than GW did with dark heresy and support it after it sells out all over the place instead of dissolving the company that makes it immediately after release. *sigh*
Dont you see, this is all thanks to the extended copyright terms! Now that copyright stretches so far into the future, artists are happy to make more material independently, safe in the knowledge that their intellectual property is protected for years to come. Imagine how much better things would be with even longer, more protective and aggressive copyright terms!
Cant you just see this movement being spun that way a few years from now?
If restarting the modem helps, could it be a buildup of heat in the modem? That was a factor causing a lot of downtime/dropped packets on a DSL connection that someone I know had. Turns out they had the modem in an unventilated cupboard and around spring/summertime it just choked from the heat.
When you order pizza and they ask for your number, do you have to consult your address book?
My pizza company (and most delivery companies that I use here in London) just use caller ID, so no I dont. However I think that they now recognise my voice thanks to my ongoing mission to eat my own weight in pizza every month:)
I'll add to this by mentioning that in many cases, thanks to the client/server setup of mythtv, you can just put a few TV cards in your file (or other) server which you might already have at home (like I did) and then use a very efficient client based around VIA/mini-itx for the frontend, which is still a bit more than a set top box, but is still an improvement.
I am just posting to try and get the general/. attitude towards Xen... Xen seems to be the fastest virtualisation option by quite a margin, and has excellent features (pci device forwarding anyone?), but will never be in the official linux kernel by the developer's own admission.
Xen has a number of unfriendly (minor) glitches. It is locked in to specific kernel versions unless you really want to have a lack of stability. On the Xen mailing list developers have stated it is not suitable for enterprise use yet.
I was wondering if people are feeling positive about the future of Xen in general? There is still an active developer community (perhaps equivalent in size to mythtv a year or two ago), but will Xen be beaten back by the rapid advance of other technologies, or are the benefits from Xen enough to keep it rolling forwards regardless of alternative virtualisation products?
FWIW, I have 9 Xen virtual systems running on one core 2 duo server (3GB ram) now, and will be pushing that up to about 12 systems as a 'network-in-a-box' solution to a lot of my coding and home network requirements too and I am generally a big fan. I prefer vmware by a long margin for ease of use, but in terms of raw power Xen seems to have vmware beaten by quite a margin (and the PCI passthrough is very very useful for a print server and for playing with network cards). I think Xen will obviously continue to grow but I cant help but wonder if it will fall too far behind a few years from now.
The latest (subversion) version has an option for using the video manager as a way of browsing the directories. It actually just automatically re-scans your video folder if it detects anything has changed, which means you get a delay when clicking on the menu - still far from ideal, but at least there is no longer a need to go to the setup menu to view a new video.
Dont worry about itunes, install amarok and you will never want to go back to itunes again. A nice comparison between the two can be found here. Nice comments after that article too 'In regards to music management, amarok beats the shit of out itunes'.
Although a bit late for xmas now (or is it), I threw together a brief, 1-page, tech geeks gift list a while back which can be found here. Hopefully it is not modded away into oblivion as being too link-whoreish!

pff just a rip off of Jules Verne's Mysterious Island
IIRC, XMBC is only doing a dedicated, purpose built front end for PVRs. You'll still need mythtv on the backend.

Just posting to draw attention to the parent post. Mods, mod it up as I dont have any mod points right now!

Not to mention how much this will help us defend against the cylons!
The real problem in the US is that you dont have Kitchen Gun, especially considering the US's love of all things shooty!
