.. a slashdot topic on which I might actually be qualified to comment.
I’ve spent a lot of time analysing suitable databases for data warehouse. As other commenters have mentioned you don’t really give enough detail about the types of data and likely use cases however I can assumer your going to do similar things to most of our customers. We have used 2 products in our business, both are column stores which tend to have the characteristics of very fast read/join and query but should not be used for anything remotely transactional.
Initially we used Infobright which has an OSS community edition which for a Kimball-style data warehouse will happily take you up to 2-3 million rows before the query performance on more complex joins starts to creep over 1-2 seconds.
As we took on larger clients we switch to Amazon Redshift. This is essentially a fairly distant cousin of Postgres with a bunch of technology thrown in from parexel. we found it the best performer by far in terms of bang for buck (you need to use the SSD disk option) when compared to things like Teradata (mentioned above) supports encryption and is very easy to get up and running with.
If you follow Kimball’s http://www.kimballgroup.com/ design patterns you cant go far wrong but keep it simple at all times.
We use Talend for ETL but are in the process of developing our own technology and Jasper-server Commercial for out front end
Disclaimer: I have no direct interest in the products mentioned however I am CTO of a BI/Data Warehousing start-up (www.matillion.com) and have spent plenty of time in the trenches with
Sound like total rubbish to me. Politicians do lie sometimes and they even occasionaly tell the truth but mostly they bend the truth out of all proportion. If they make a statement its not TRUE or FALSE usually the answer would be "WELL... ITS COMPLICATED.. it depends how you look at it"
In the UK we have a radio show dedicated to statistics called More or Less
http://www.bbc.co.uk/programmes/b006qshd
These folks can spend half the show discussing the truth behind a single political statement and then sometimes dont come to a firm conclusion
cant do commands means you cant script, cant script means you cant automate, means u waste time clicking through the same UI to perform the same tasks means your not an effective admin
If you go to pirate bay and click top 100 you will notice that almost everything in the list are movies. Now, if you have ever watched a movie to the end you will notice that there is huge long list of people who worked on the movie and most of these people are not movie stars and directors they are regular joes who, as far as i can tell need, probably deserved to get paid.
Now i know that the movie industry and the MPAA arn't exactly whiter than white, however i know who will suffer everyone decided to pirate their movies.
Pirate music and music will probably get made, pirate movies and new movies simply wont get made.
"Flickr compresses their images at libjpeg quality of 96 and Facebook at 85: both quite a bit higher than the recommended 75 for “very good quality”. Neither of them optimize the huffman tables, which gives a lossless 4–7% improvement in size. Further, switching to progressive JPEG gives an even larger improvement of 8–20%."
Canonical's code contribution is irrelevant. What open source has always needed is some polish and some marketing. Thats what canonical provide, they polished and marketed (to an extent) a decent distro. OSS has never been short of decent code and quality software engineering. Canonical are providing a great link in the value chain of linux and as long as the basic prinicipals are upheld im all for it!
Sorry but that just plain rubbish I have a bunch of IBM certs because IBM make us take them to keep our partner status. Ive seen sheets of answers being passed round so people can memorise them, pass the cert and carry on doing something useful. The only certs i would pay any attention to are ones with a written component such as SCEA (Sun (oracle now?) Certified Enterprise Architecht). Even then its probably pretty easy to rip off the written component from somewhere.
IT industry certs are a joke. Basicly what happens is:-
1) Guy pays off certification center in india works through the exam a few times untill hes seen all the questions in the random pool 2) get answers to all the questions (do a shitty job) 3) Sell answers on testking.org or some dodgy site as a "guide" 4) profit
nah, they cant show me the movie without really [i]showing[/i] me the movie so the data is decrypted somewhere and the pixels in my tv are told what colour to go someone is always going to be able to grab the stream and make a good ol' file our of it. once that file is on bittorent all the effort you describe will be for nowt, in fact if bandwidth realy is cheap you wont even have to download it form a BT site you can get it from some kinda pirate 1080p streaming site
Yeah man chinese traditional medicine is awseome.... you only have to go back to the 60s and average life expectancy in china is a whopping 36!.... that traditional medicine must really rock...
I stuck my mum on ubuntu and shes never looked back. My sister has just called me to tell me her XP laptop is spamming popups, giving spuroius virus messages and generally sounds like its in a world of pain. I cant wait to spend 2-3 hours tonight mopping all that crap up
Yeah your right we should just give up trying to demand open standards. Lets all throw our hands up in the air and burn our computers.... or we could take this as a positive move in what will be a very slow and torturous process
This is a good reason to boycott MW2 but the better reason is the higher price point. All the retailers are selling WM2 for at least a fiver more than a normal triple-A title. If it sells well then you can guarantee all new games will move to this price point.
Yeah, and they could make those guys lives easier by building a fence... like, out of wood, or bricks or wire.... give em something to walk along!
In fairness even half a mile is still quite a long distance to patrol if there are determined people trying to get through... in fact if I was patroling it as a geek i might erect some cameras and motion sensors to help me along and get my colleagues to do the same.... hmmm

Yeah Lenovo keep on diluting the range little but little with inferior models, my advice is nothing but nothing but T series
Yeah, and how do you make all that happen? You have an approval process like Apple so if any one of your rules are broken MS can tell Norton REJECTED!
perhaps your post should be entitled "11 simple reasons why giving developers freedom ands in a clusterfuck"
similar sentiment here in the uk where people think big old volvos are safer than moder cars.. not true...

Yeah there is a nice blogpost linked from the bug with a good explanation. http://muizelaar.blogspot.com/2011/04/webp.html. I was especially interested in :-

Neither of them optimize the huffman tables, which gives a lossless 4–7% improvement in size. Further, switching to progressive JPEG gives an even larger improvement of 8–20%."
who give a crap about where the ideas come from, its ability to execute thats important

public sector is incompetent but at least its well meaning incompetence
private sector is incompetence combined with greed
ill take the first one

1. create complex new search engine type technology
2. create webcast of launch
3. announce on slashdot
4. fail!
I wonder why people dont create records of sites going live... perhaps its cos the poop always collides with the fan!
