  1. Re:Yea, it's all the same. on Are Relational Databases Obsolete? · · Score: 1

    So say Bob makes 50,000 dollars. This entry was put in the table when he was hired and contains bob's employee record id, bob's salary, the date, and the audit crap. That's it. Then when bob gets a raise to 55,000 there is another simple entry, id, salary, date, audit crap. Etc, etc. All your data is there, you can easily retrieve the history, you know when the changes were made and by whom.

    Let's say Bob was hired 20000101 with a salary of $50000. Bob get raise 20050101 to $55000. Bob gets fired 20060606, Bob gets hired again 20070501 with the salary $10000. What is Bob's accumulated salary and how much has he earned on average every month? What was the average salary of the whole company in 1999? How do you prevent someone from inserting a row stating that Bob's salary was $99000 in 20070101?

    The answer to all of the above is some very complicated queries, stored procedures and triggers. When you are dealing with temporal data, the relational model doesn't fit anymore. You need something else and better.

    I wonder where to draw the line between truly normal price decreases, and jacking the price on something you know will sell like hotcakes...I'm not all that business-savvy, so feel free to educate me if there is indeed such a line.

    Supply, demand. If the stupid iPhone was selling like hotcakes right now (high supply), then you wouldn't lower the price with $200 because that is the same as losing $200 on every product sold. Therefore, not as many people wants an iPhone right now (low demand) and earning $200 less is better than not earning anything at all. Something is fishy!

    The sane thing to me seems to be to just skip the oltp step since the data contained therein is a strict subset of the data in the warehouse. Let's say you design a relation database for a company. You have a table with Employees and another with their Positions, a Project table and so on like the orthodox relational model tells you to. Which works great until someone quits, then you have a problem.

    Naturally, you don't want to delete that person because then you lose lots of important archival data. So you introduce two fields in the Employee table which contains the dates when the employee started and quitted. You also need to do the same for almost all other data. If Bob gets a raise, you don't want to simply update his salary field, you want the data to state that Bob had salary $x during the dates $A-$B and $y during the dates $B-$C. So you need even more fields for validity intervals to fully describe your data. It gets incredibly messy, all your queries becomes really complicated and you need to employ stored procedures and triggers to keep your data intact. The relational model breaks down.

    What you need at this point, is some kind of "event based data storage." Like "Bob got a 5% raise 20070801" or "Company address changed from $x to $y 20001010." For these kinds of data, a warehouse is much better suited. A column based storage would probably also be much faster than a row based for it.

  4. They receive enough money on ISPs Dragged Into Swedish File Sharing Battle · · Score: 1

    Actually, an overarching broadband fee which would be shared out among copyright holders might be the most sensible way to deal with this whole mess. And not just in sweden.

    Yes, it is a good idea and it does work. The thing is that in Sweden, we already have these fees in place. We have Svenska Filminstitutet, Film i Väst, subsidies from the EU, Kulturrådet and dozens of other regional and national institutions in place to support movie makers, music artists and writers. We pay lots of money in taxes to subsidize the movie industry because it is very hard to make profitable movies in Swedish. Each movie gets many millions in subsidizes from the state which is the only reason why people still make movies here.

    That's fine by me, quality often not profitable. But it is not ok when these same people decide to turn the backs on the people that, in reality, feed them and demand even more money. I think it is my moral right to download every Swedish movie I want, for free, I already payed for it. There should be some kind of rule that each company that complains about file sharers is banned from receiving subsidies, see how long that lasts.

Are you actually trying to argue that women are NOT more social than men? Yeah, the comments about yapping, gabbing, catty women are low-brow. That doesn't invalidate the basic point that women are more inclined to gossip. It's not sexist, it's truth. In other news, men have penises.

    But what the fuck you literal dickhead. Slashdot is a blog which you are reading and from a quick glance at your userpage reveails, have written 3829 comments to. That makes you a pretty "chatty" person and, unless you are a female, does "invalidate the basic point." There are over a million other mostly male users on Slashdot wasting away their days reading and writing stupid comments, and if that doesn't prove that men are just as yapping, gabbing and chatty as women then I don't know what.

    But somehow, writing comments on Slashdot is considered equivalent to partaking in a high-brow, intellectual conversation so Slashdot is "good" while discussing pie recipes on some blog is considered yappy. Well, check this stupid article and the fucking morons posting their boring gender-stereotyping jokes that they probably learnt from a porno-mag.

    From the research that has been done in gender differences, very few conclusions can be drawn. Yes, men are in general better at chess and Sudoku while females are better in Scrabble and crossword solving, but the facts ends there. You cannot from the available evidence try and conclude that women are more chatty - the facts are just no there.

    How can they be self-sufficient when their economy is totally dependent on exports? They don't have a significant home market so if some countries decided not to buy from them or add trade tariffs, they would be pretty much screwed. One billion DVD players is only worth something if someone buys them. On the other hand, the way the US is going, they are losing their own market due to reduced purchasing power of the population and increasing economic inequalities. That is, it is much more a threat to the US economy that the standards of living is increasing in China because when enough Chinese can afford to buy DVD players, they don't need to sell them to the West.

    It's not a Socialist idea to think that the state should be responsible to provide basic services (yes, broadband is becoming a "basic service") to its citizen. I think it is just common sense.

    It is all just endless streams of bull shit. Consider how much it cost to do the original copper telephone network, which contrary to the bull was far, far more expensive they any new fibre network and guess what the population has risen since then quite a lot in fact, so not only is copper tech more expensive but it had to be done with a far far lower population density, it had to be done with far more primitive technology, it had to be done using backward switching technology, telephone exchanges as major buildings and even the local was not a box but a whole building. Think each and every copper connection had to have it own line, it's own independent bit of wire, nothing like fibre at all with thousands of connections down the same line.

    Key is who built it. Building a network with 99.99% penetration isn't economically defensible, you don't make any money providing fibre to a single family 100 km from the nearest town. It is an investment that it takes 50 years to become profitable so no company would ever do that. However, a fibre network to each household benefits society in a number of ways, just like telephone lines do. Which is why it was state owned entities that built the telephone network. But in the US, it is somehow expected of the cable companies to provide a completely covering network. So strong is the American belief in Capitalism that companies are expected to do things for the greater good of society even if they cannot profit from it.

    The world just doesn't work that way. But in the US they have choosen the low taxes and each man for himself way and crappy infrastructure is the price they pay.

Tech companies want to emulate and then we only reap the benefits. I bought a Creative Zen instead of an iPhone, but I admire Apple for pushing the competition.

    That is certainly the optimists view. What tech companies want is profit, and Apple certainly has generated quite a bit of that, so yes, other companies will definitely imitate Apple. But it is not technological innovation that is selling the iPhone, it is marketing. Apple spent hundreds of millions of dollars before the iPhone was launched trying to hype its phone and they are probably spending even more now when it is on the market.

It would select one race (or ethnicity) -- indegenous, non-Saami, blue-eyed blonde Swedes -- and exclude other ethnicities. On the other hand, stating that Sweden is the homeland for the Vikings would probably be ok. Vikings aren't an ethnicity (not anymore atleast) and it would be just as easy for a Vietnamese or Egyptian to become a real "Viking" as for anyone else.

    But what journalists and editors at New York Times and other American newspapers claim, is that Israel is the homeland for the Jews. That is definitely racist. Jew is a specific ethnicity and so the claim excludes other ethnicities in favor of that one. Pretending that that is not racism is just hypocrisy and the only reason why it is accepted is because the Israeli-American lobby is very strong.

Sweets give the same kind of reaction in the brain as crack. The easiest way to make food taste better is to add sugar to it. Everyone who cooks knows that, just add more butter/whipped cream/sugar/chocolate/what have you and your meal will taste better.
