I've been working with databases for quite some time including teachers assistant at DIKU (CS at Copenhagen University) and I don't think it will come close to any of the books we teach, it does give you a great basis to work from when switching to those books.
Having something that is lighter read to get started with so you get the basics will help you a long way (YMMV).
I've bought both the database one and statistics one and I must say I agree with the review, these books does a great job of giving a novice a quick introduction to the world of databases/statistics. While not covering everything, they will build up some base for the reader to allow him to read more in-depth books that might have been to heavy to start out with.
I for one sure as hell had a hard time understanding statistics.
I don't care about ads, what pisses me off is when some site uses some overloaded server in Germany or where ever to serve up ads. I block those sites because they slow down the surfing experience - want to show me ads, bloddy well host and screen them yourself.
I find it ironic that you use string concatinating as example for something someone should know as they rarely should take more than then length of the strings to copy to a new place (and take up some vast amounts of memory) and at the same time tell us you are more than willing to throw hardware at a problem that could very well be running in O(n^2) or worse.
The best part of that cable is the fact that it is actually pretty poorly made. Look at the plugs, there are no guards, you can easily snap off the click thingy if you are careless.
4 inches = 10 cm. The worlds ocean has already risen that much, compared to for instance 1920s we now have 20 cm more water than then. The forecast for the next 100 years is somewhere between 9 cm and 90 cm.
While 10 cm might not seem like such a big deal it will cause corrosion of the cost lines at a higher pace. If we get the other end of the scale we are in for some real fun since most of the worlds population is located very close to water.
Now a meter might not seem like much, but having one more meter of water will cause massive floods during storms, just look at the fun the US had with Katrina, now imagine you don't need a cat. 5 hurricane to cause those kinds of floods.
Actually the 100 krona incident has nothing to do with Conficker, but the current exchange rate, the machine realized that Icelandic Krona was dropping so fast the money wouldn't be worth the paper it was painted on, and decided to dump the lot.
Well said, I used to laugh when I saw people defend MySQL, these days I get the urge to cry knowing fully well that some day down the line someone will call me up and ask me to help them fix their lost data.
The worm tries against 50.000 new domains every day. That is quite a big number to match against - also the ISP needs some incentive to throw money at keeping this database up to date, there are no money in blocking the worm.
Also the algorithm might hit innocent domains once in a while causing you to threaten innocent users.
Also the quality of the reporting has gone to shit (in Denmark).
Back in the olden days in the before time before internet, becoming a journalist was extremely tough (here in Denmark), you had to have a high average in high school and getting through journalism "school" was tough. Back then reporters could spell their own name without looking it up, they could ask intelligent questions rather than just writing down whatever their subject was saying.
These days you have to look hard to find a single article that hasn't been written by someone who has absolutely no grasp of whats going on, nor free of grammatical/spelling errors.
Paper or electronic, I'd gladly pay a fee for a proper newspaper, but I can't find one any more...
Not sure why you got modded insightful, Intel very much need both AMD and NVIDIA since both competitors are sitting on key patents to their chip (and vice versa).
CS has nothing to do with programming. Code is just the end result. No autodidact person I've ever met understood NP complete problems.
Also from experience, the smartest CS person I know woke up one morning, realized he was stuck in a dead beat job with no promotion path. He quit his job took math on a summer course and started studying CS (the proper kind), he graduated last year and is currently applying for a Ph.D with multiple companies offering him very high payed jobs, he is 37 now, married and 3 kids, but worked his ass off and got there.
I had the joy today of trying to use OO to make a spreadsheet from CSV, christ what a load of crap.
First up I imported the set, realised I needed to compare it to an earlier set so I just dragged the file into my open window expecting it to make another spreadsheet. Well guess again, it just wrote over my current data - hitting ctrl+z didn't revert it. Great, so I closed my current spreadsheet wanting to start over and hit ctrl+n for a new sheet, so what popped up? Writer.. wtf?
Ok, closed the application, made a new instance, made sure to ask it for an extra instance before importing data from both the CSV and the earlier sheet. So far so good, did some calculations and wanted to save it; of course the target of this file is on MS so I chose excel 2003. "Unable to write file" wtf? no indication of what went wrong, just didn't want to write the file, I tried all sorts of permutations of file name, but to no avail. So I changed the format to 2000, saved it just fine.
These issues might be PEBKAC, but I sure as hell will stay clear of OO as much as possible; one of the most important tasks of a program is to do as a user expects, overwriting data with no apparent undo path and error messages that doesn't give any kind of hints to what is wrong is just downright unusable.
Because DNA isn't some color coded ring magic on a computer. What you get when you do DNA extraction is a set of markers you match up with whatever suspect you got - so if the DNA is contaminated you will just get different markers than the "pure" DNA.
Here in Denmark a chain of shops that deal with items costing between $1 and $2 (guess you guys call them dollar stores?) has started its own label - it is a no bullshit label, you get 50% of profit from sales, default print I think is 1.000 CDs or 10.000 and the shop carries the risk.
CDs are selling like you wouldn't believe it - apparently people are willing to pay $2 for a CD from a group they never heard of (I for one am, heck if it sucks I can use it as a fancy coaster).
This is when small companies start to thrive again.
Suddenly the monoliths are too big and greedy to carry their own weight and the small agile less corrupt will be ready on the sidelines picking up the spill.
While your car analogy is totally bogus, it is also totally irrelevant.
First of all, driving 2 hours to pickup a pineapple would never ever be cheaper than buying it locally, when you factor in the time to get it and the drive to and from.
With steam it is the exact same content server, the exact same shop - everything is the same, except for the fact that they are forcing me to pay in rather than $ or £ - keep in mind, my country (Denmark) uses DKR and thus defaulting to Euro might make sense, but so would dollars since most trade we do with outside world is in dollars.
Also Norway who isn't even member of the EU (Denmark is) are also forced to pay in .
So what open source database supports those things?
MySQL has speed and redundancy (but not subsecond fail over and it needs some tool to handle the failover for it), but MySQL lacks reliability.
PgSQL has an ok speed, it is very reliable, but it lacks redundancy (yes there are people who have written all sorts of trigger based replication schemes for PgSQL, but they are unsafe, and like the MySQL option needs something else to handle the switch to primary).
There might be some obscure OSS database that handles these things, but I haven't heard of them yet.
Enterprise / Carrier grade databases are databases that even during catastrophic failures (fire in one data center, massive hardware failure in one server etc) are able to keep turning out transactions - at slower rates, but transactions are still going.

You are going to have a hard time convincing a judge that the ad you blindly serve up from some ad-site in Germany is essential to the content.
I don't care about ads, what pisses me off is when some site uses some overloaded server in Germany or where ever to serve up ads. I block those sites because they slow down the surfing experience - want to show me ads, bloddy well host and screen them yourself.

Also insightful? geez.
Actually some cables might come with diodes, I got one that is directional because of that.
While I do agree that that Denon cable is pure piece of crap, you can actually hear the difference between low end and mid end equipment.
I changed an Harman Kardon surround receiver (AVR-2000) with a Denon 2809 and there is a huge difference in the quality of the produced sound.
Yes, but those fixes where made to get people home, no one was thinking of using those same solutions as the standard for next flight.
The best part of that cable is the fact that it is actually pretty poorly made. Look at the plugs, there are no guards, you can easily snap off the click thingy if you are careless.
Uhm.

This is why we have digital signatures.
Here in Denmark at least it is possible to authorize people through digital signatures (all though very few sites use them).
Also the quality of the reporting has gone to shit (in Denmark).

Actually he is somewhat right.

The olden ways are dead, just a matter of time.

That's probably because you are paying in dollars.
I stopped shopping games in steam when they forced us to use Euros - but did the conversion 1:1.
Also its set to go off on 1. April, so when the internet is down and nukes are flying people are just going to laugh thinking its a hoax.

PgSQL does not scale out, only up. Enterprise is out of the question here.
