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.

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.

Comment Re:High density = no digging (Score 1) 257

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!

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)

Submission + - A new way to find code

tabandmountaindew writes: Too much time is wasted re-implementing code that someone else has already done, for the sole reason its faster than finding the other code. Previous source code search engine, such as google codesearch and krugle, only considered individual files on there own, leading to poor quality results; making them only useful when the amount of time to re-implement was extremely high.According to a recent newsforge article a fledgling source-code search engine All The Code is aiming to change all of this. By looking at code, not just on its own, but also how it is used, it is able to return more relevant results. This seems like just what we need to unify the open-source community, leading to an actual common repository of unique code, and ending the cycle of unnecessary reimplementing.
