I refuse to print out my presentations as slides for my students. I've done it in the past and one semester I had the students ask me to stop, they preferred to write their own notes. Why would you print them? I'm sure most of them can work with the files.
Fixed it for ya. I always wondered if having your product be "Naive" spelled backwards was an inside joke on the part of some marketroid. If you buy it regularly, it's pretty dumb. On the other hand, they have nice bottles that don't make water taste like plastic, so I'll buy a bottle and keep refilling it out of my Pur filter for a year or two.
there are some things that it's not a good idea to put into a teenager's head. I'm certainly no prude, but if my kids were looking around the internet for snuff films, I certainly wouldn't want it to be EASY.
Along those lines, it's occurred to me that it might be best to just provide my son with a selection of porn that isn't too objectionable. Nothing violent, nothing degrading and nothing treating interracial sex like a kink. If that will keep him from wasting time searching for it and keeping him from stumbling across stuff I would object to, it seems like it would be a good thing.
Right. I just used one in the last couple of days for reading columns in a spreadsheet. I don't know exactly how many there will be, but it's not likely to exceed 2-3 dozen.
I'd guess that only 25% of the population (tops) even has the potential to become a useful programmer. There is something about being able to decompose a technical problem into its constituent parts and then generating solutions for each of those parts that is simply beyond the capacity of the vast majority of people. You're talking about basic personality type differences. On the Meyers-Briggs scale, you want ?N?? people, or in basic terms, people who prefer thinking about abstractions to thinking about concrete things. Software *is* abstraction.
If its trivial/small, use an array or a delimited string list of ID's. Sure, you could, but the linked list version is usually simpler if you don't know beforehand exactly how much data you're going to have. Especially if the data is small enough to recursively follow the list, it can be a marvelously lazy way to solve a problem.
There's a reason why the GP specifically said naked pointers. Because he or she wasn't paying attention? We were originally talking about linked lists in C#, which you would do with object references.
The medium involves coiled wire on a silicon chip and "sliding" magnetic ones and zeros down "notches" in the wire. From the article's description, it sounds like it isn't "sliding" magnetic data in a metaphorical sense, but actually physically sliding magnets around. This sounds kinda like the nanomechanical computers the hard-code nanotech people (Drexler, etc.) talk about, although I'm not clear if it's quite down to that scale, yet.
It could be very cool, but I do wonder about the shock resistance of such a device.
The new AT&T needed a wireless carrier and negotiated the purchase of Cingular. Not as a separate decision. Cingular was a joint venture between SBC and BellSouth, which are now both AT&T.
It depends on the judge. My wife was on a murder jury a couple years ago and ordered to stop taking notes because no one else was, and her opinion would then be given undue weight by the others.
What was the last version you used? Table variables were introduced in 2000, and they're a big improvement. I haven't used 2005, but the error handling is supposed to be drastically improved in that version.
Anyway, I won't deny that PL/SQL has some major advantages over T-SQL. The "For record In (Query) Loop... End Loop" construct is wonderful, you can just directly read and write files without dealing with DTS nonsense, you have TCP and HTTP libraries (I've actually written a couple of web service clients in PL/SQL), anchored variables are very nice, triggers are more versatile, etc. It's clearly a far superior procedural language to Transact-SQL.
Oracle's downsides are more subtle than T-SQL's very limited feature set. While the "@" sigils in T-SQL variable names seem silly, they make name collisions between columns and variables impossible. T-SQL is just one language, while Oracle programming is split between SQL, PL/SQL and SQL*Plus, with hard boundaries between them, and different functionality in code depending on whether you're working in SQL*Plus, SQL Developer, TOAD, ADO/JDBC, or some other client. While Oracle is better at procedure work, T-SQL lets you do a lot more in set-based operations, with table variables and much easier use of temporary tables. In T-SQL, whether you're in a stored procedure or not, any SELECT query with no target is just returned to the client connection (especially handy for ad-hoc data analysis in Query Analyzer), versus a reference cursor system in Oracle that I still haven't figured out the syntax for. Oracle makes everything all caps internally, and displays all caps, forcing names into a__naming_style I outgrew when I was 17 years old and have avoided since I discovered ABetterOne. Oracle names can't be longer than 32 characters. Blank strings in Oracle are automatically turned into Nulls. PL/SQL has a real binary integer type, but Oracle SQL doesn't, so it can't be put into a table, or used as the return type of a function you want to use in a query. Oracle SQL doesn't have SQL Server's (admittedly non-standard) "Update Table1 Set Field1='' From Table1 Join Table2 On Table1.ID = Table2.FK" syntax, necessitating more subqueries and/or loops instead.
I won't say T-SQL is better than PL/SQL right now, but I do think it's going to improve more in the future by adding features, while Oracle is basically stuck with the poor model they've got.
In fact, it was very important to the founding fathers that we not have a king. I really wish that people would remember this. The founding fathers were not a monolithic block. Alexander Hamilton actually did propose a for-life executive position at the constitutional convention.
It wasn't so much that Hamilton was a fan of monarchy as that they were trying to work out a meaningful separation of powers so that there was something more substantial than just a 2 year vs. 6 year delay in getting every damn-fool authoritarian idea from The People implemented. This eventually came from the supreme court, after the Marbury v. Madison decision, but the Republican party seems to be opposed to that, now, with their complaints about "activist judges".
I can't begin to tell you how often the words "FoxPro" and "MS SQL" You do know those aren't remotely comparable, right? FoxPro scales to more users than Access (due to tables separated into different files), but they're otherwise on a similar level in terms of what sort of jobs they're appropriate for. MS SQL Server is a full-fledged enterprise RDBMS. It may not scale quite as far as Oracle or DB2, but it get closer every generation, and having worked mostly in Oracle for the last year or so, I've been missing SQL Server.
I just bid a job a few months back that would cost $150,000 to upgrade their database infrastructure, and likely save the company $300,000+ annually in added efficiency, less downtime, and a more robust report system. Guess what they said? "We all think it is fine the way it is." That was probably a polite way of saying "We don't believe you.". Maybe you made a case to them for why relation is obsolete, but you certainly didn't here.
Instead of passing around abstract id numbers, it would be nice if we had reference objects that abstracted programmers away from the temptation of manually managing identifiers. I've thought about that, and I think it would be great within a stored procedure language, but it wouldn't work so well when you're pulling in data from an external program.
Why on Earth are we still using WWII-era bombers? Are they just hauling equipment around until they can no longer be repaired? Apart from the correction on the age that everyone else has pointed out, the air force realized that absolute air superiority has been no problem in any of our recent conflicts, and it wouldn't be a problem with anyone we're likely to fight for the forseeable future. Given that, there's no reason not to stick with what's basically an airliner with a bombadier, since we already have them.
The B-1 and B-2 can make successful attacks in much more dangerous environments, but there's just no need for it these days.
Because we make a distinction between stuff that we know we want to keep and stuff that we don't (yet, at least). For the stuff that we don't, if the system runs out of RAM it starts using disk space.
There have been proposals for systems where saving is invisible, but I don't think I would want to use such a thing. I like the hard distinction between temporary and permanent.
Do the solar cell fabrication factories use solar power? I have a friend who works at one (well, they make panels, not cells), and they're working 'round the clock, so they do use grid power at least some of the time.
On a more serious note, why aren't we just using a giant fiber-optic array on the roof which splits into smaller cables running to the rooms of the house? There was a Slashdot article on someone working on that, too, a few months ago. It was a parabolic reflector dish concentrating light on the ends of a bunch of fiber optic cables. They were also talking about later versions separating the infrared and untraviolet components for hot water heating.
But most people don't want to live in the middle of the desert, which just happens to be is where areas of maximum insolation are. True, and I don't want to live there myself, but an awful lot of people do live there, and they use a hell of a lot of electricity on air conditioning. Los Angeles, Phoenix, Tucson, Las Vegas, Albuquerque, Dallas, etc., could probably be powered largely with solar power.
I seem to recall seeing something recently about a fairly sizable solar plant under construction now outside of Vegas, but I couldn't say where I saw it.
Run on the grid, and share power during the peak and we vastly augment our thirst for oil, but we can never truely become independant unless we figure out a way to vastly improve power storage. Only if we insist on using the same technology for all power generation. Wind power also varies by time, but not on the same schedule as solar. Photovoltaics are nice and easy and well suited for distributed generation, but bigger solar plants can use the heat of the sun and store excess heat during the day to get some continuing generation at night (and some are already doing this). Hydroelectric and geothermal power have pretty significant limits to where they can be used, but where they are available, they're nicely stable. Tidal power generators fluxuate through the day, but on a predictable schedule.
Now, some storage is probably going to be necessary for use within buildings to eliminate fossil fuels and nuclear power (a much lower priority than fossil, to my mind), but I think that requirement is going to be a lot less significant than the energy storage requirements to power vehicles. And neither will necessarily take new technologies; there's always plant-based fuels, which you can also view as solar power storage.

I've still got a couple years to decide, though.
Right. I just used one in the last couple of days for reading columns in a spreadsheet. I don't know exactly how many there will be, but it's not likely to exceed 2-3 dozen.
Go to Best Buy, then.
