As an FYI, EXISTS performs slightly better than an IN for most queries with no major change in the code. EXISTS gets to benefit from stopping once a match is found as opposed to running the entire sub-query before searching the results. The only time they are close in performance is when what you are matching is at the end of the list. And then, they are more or less equal.
Of course, I normally change my code to read:
select from Table where exists( select 'TRUE' from Sub-Table where )
Instead of
select from Table where in ( select from Sub-Table where )
But that isn't required to get the benefit of an EXIST clause.
I do admit it is funny and somewhat ironic, but I chalk it up to my SQL background as to why I DON'T use the operators when searching. I tend to use multiple windows/tabs to search, so if I'm going to do an OR, I'll just run the query in two windows. When you throw an OR into a SQL query, you can kill performance of that query. A lot fo the time a UNION of two result sets is faster than the same query with an OR (sometimes not, Query tuning is a form of technical voodoo). Of the operators, the one I use most frequently is -, but again, only when normal methods fail. A NOT operator doesn't use an index well.
As a side note, I prefer multiple windows vs multiple tabs. With tabbed browsing, all pages are running in the same memory space. If one result has a bad page (by bad, I mean slow / resource intensive), it bogs them all down. I have my browser set to run each different instance in a different memory space. New window means that the others still perform ok. And if I need to kill the offender, it doesn't take all of my windows with it.
Yeah, I second the "good searching skills" vote. My rule of thumb is that if I'm trying to find something and it takes longer than 2 hours, it isn't really available on the Internet. Most things take less than 15 minutes, obscure things less than 45.
For those who aren't good at finding things the following are some good tips: 1. A good vocabulary / thesarus is very handy (which rules out half of/. already). 2. Good and bad spelling is important. Just because you can / can't spell a word, doesn't mean that everyone else can / can't. 3. Word order can be important, too (even on engines that say it isn't). 4. While I rarely use operators (AND, OR, -, etc.), knowing them is good for that hard to find query. 5. Quotes around multiple words are more important that the operators. It means that the words have to appear together and in that order. 6. My engine of choice is Google, but targeted engines might get you better results.
A quick and easy way to spoof a MAC address (no hacking knowledge required).
Get a Netgear wireless router (I'm sure other brands work, too, but the one I have is a Netgear). In the set-up, it asks if you want to use the MAC of the router or another MAC that you specify. Plug in whatever value you want. Instant MAC spoofing. And it's all configurable by a Web page, so even a no0b can do it.
You pay to figure out if you are the 1 or in the group of 9. If you are in the group of 9, you need to spend more on security training / awareness. Training the whole branch office is likely to cost a whole lot more than the cost of the assessment. If you are in the 1, then you've avoided the full cost. If you are in the 9, then the cost of the assessment is easily absorbed into the total cost of securing the branch.
Wow, I thought that certain institutions were exempt (well, subject to modified rules) like a lot of other things. So, every time my kids schools have movie day they are violating copyright law. Same for day cares that use movies to entertain the kids.
And what about when I'm driving down the highway and my kids are watching something in the mini-van? If you can see the movie from your car (and can hear it from the FM transmitter), does that mean that I'm violating copyright law because it becomes a public performance?
And just because the probability is 1 in X, doesn't mean that an event can't occur more than 1 times.
Proof: The chance of a die landing on 3 for a given roll is 1 in 6. If I roll a die six times, how many times will it land on 3? On AVERAGE, 1, but for a specific set of 6 rolls, it could be as high as 6.
So, if the odds that life would develop around a star (not counting bodies orbiting that star -- I am reluctant to use the term planet because Pluto could house life and is not longer considered [by others] to be a planet); so if the odds are 1 in Q where Q is the number of stars in the universe, there is still the chance that more than 1 stars rolled a natural 20 on their Chance for Life roll.
The browser will not go away. It may expand to include more functionality, but it won't go away. People like "one stop shopping". It's called INTERNET Explorer for a reason.
The browser handles all of these activities in a single platform (either natively or through "handlers" - plug-ins if you will). Make a new protocol for applications if you want, the browser will likely be expanded to support the protocol (first via plug-ins, later natively). As a Web surfer, I don't want to have to know which program to run in order to accomplish my task (read docs, play games, use apps, etc.). I want to run one program (my browser) and have all of that "MAGIC" take place behind the scenes.

Given the choice, I'll take Jackson's "butchering" over that animated crap we had before. I agree with the guy that talked about "Which Lie Did I Tell?" (several posts ^^^ by now). Jackson's movies are visually appealing, entertaining, and true enough to the story that I didn't take a lot of issue with them. The main fault in my mind was the Arwen love story part. The rest of it was acceptable/tolerable deviations.
I've got a BS-CS degree, but I'm taking this program (http://www.austincc.edu/techcert/Video_Games.html ) which, one of the things that drew me to it was that the instructors and directors of the program are all in the industry and employed full time or run their own companies. While it isn't an accredited degree program, I think a program similar to this combined with a "real" degree (MS-CS if you want the massters level) would be the most beneficial way to go. Many in the games industry in town (Austin, TX) do recognize the program as having some merit.
I would say that it depends on the focus of the student.
Graphics programming - Linear Algebra (matrix math) would be invaluable Business application programming - plain old Algebra and maybe some statistics Engineering apps - physics / calculus, stats Compression programming - linear algebra, "new math" etc.
When I was in college (90 to 94) at an engineering school, my CS degree required Calculus through the third one (because it was in the Engineering department) and statistics (because otherwise, noone in their right mind would ever take statistics) and an elective "math" the your advisor would point you towards based on what type of work you were interested in doing. I think this approach has worked out well for me.
I would love to see this come to market. Instead of plugs, my house would have resonant antennas embedded in all of the walls. Then, I can just put things whereever I want them. They'll get the power they need (~15ft gives 30ft coverage, no room in my house is that big). The only concern would be with reception (such as cell phone or FM) with that copper Faraday cage in all of the walls. TV wouldn't be much of a problem because my TV antenna is this DirecTV dish sitting on my roof and my internet comes from my cable company through this black "tube".
Who needs backwards compatibility. My Commodore 64 still runs all of my Commodore 64 programs. My XBox still plays all of my XBox games. My DOS games still run great under DOS 5.0 (6.2 and 6.22 were where MS started pushing bloatware over beneficial functionality).
I'm in favor of trimming some of the fat. If MS has a 3 version back support policy for the OS itself, why not have a 3 version back support policy for any features. After 3 versions, you may or may not get to keep your API. They do it with other areas (for example, SQL Server has not guarantee that certain features will be supported in the next release and MS recommends that you update your code).
I'd recommend one pass through the game in Wizard mode (see documentation on how to enable it). You get to see everything and it doesn't resort to save scumming (since you can prevent death). Plus, you don't pollute the high score table. Then, try to repeat in normal mode. Repeat until successful.
