Role theory provides an interesting take on the whole final exam thing. The way I understood that theory is that the behaviour of people is shaped by the role they are in (duh). A person that is a police officer behaves in a police-officer-mannerly way. This also applies to other people: you approach a police officer in a different way then you approach your beer drinking buddies, because you are aware of the role that the police officer is in. If the police officer wants to join his own group of friends and drink beer with them, he'd be well advised to remove his uniform first to make sure they don't treat hem as a cop but rather as a buddy.
What role theory stresses (at least the book I read did) was that changes in role must be visible to your surrounding if you want to succeed, else you will be held back by the stale view that others have of you. Final exams provide that highly visible opportunity to change roles from student to practitioner. It is very important that the people in your surrounding perceive them exams as important, else your role will not change in their view. Viewed this way, the purpose of final exams is not so much to test whether you are able but to provide a significant hurdle for you to clear.
Mea culpa. Apparently the answers are not listed all the time. In fact when I now checked they were not listed either (maybe they're reading/. too;) ).

"View Solution" would be what the OP called [lame subscription button]. If you had bothered to read the OP you would have scrolled down past the lame View Solution button. There you will find all answers to the question. I've just checked it for the link you gave and they are there.
There is never a government expectation of removing the toll from a road.
your government != all governments. A 5 mile bridge in the Netherlands, the Zeelandbrug, was converted from tollbridge to free after the cost of the bridge had been earned through the tolls. The same will happen with a new tunnel, the Westerschelde tunnel, that has been built in that area. In Belgium the same has happened with the Lievekenshoek tunnel, if I remember correctly.
Public funds already paid for the project, so you can't really justify putting a toll on it to "pay for it".
Sure you can justify that. I think two criteria should be met:
- the expected economic benefit is insufficient to justify paying the project out of the regular tax income. - The project cannot be funded through commercial entities, for whatever reason.
If these criteria are met and there is a strong wish to execute the project, then the payback-through-toll option is a very valid one. For instance, the projects in the Netherlands I mentioned are located in sparsely populated areas. It would not be fair to pay for them with regular tax money, since 90% of the population will rarely if ever make use of them.

If you're willing to use Flash there is actually a very nice way to implement push in a webpage.
Through a simple Flash movie you can set up a continuous two-way connection with an text or XML server. You can call Javascript from Flash and vice versa so the Flash movie on the client is nothing more than a message gateway. Best of all, you are garantueed to receive a client-disconnected event on the server if the browser is closed/crashes/obliterated or moves away to another page. I've used this techniques a couple of years ago to implement reliable locking and notification in a webbased groupware email client (we wanted to provide immediate notification of incoming messages to a group of people will assuring that only one person was typing a reply at any one time). I'm using this technique now to implement a realtime machine monitoring tool.
One drawback is the server application though: you need to roll your own (alhough you could implement a stock server and plug in an application-specific module) and host it on the same server as the webserver. Flash will only allow you to connect to that server. So this is mainly useful for intranet situations where you can actually install a server app.
buy an Asus laptop. I've had no end of joy with their hardware, especially with my laptop. They have offices around the world, so you may even be able to claim your warranty in different countries.
Interesting view. But I think you're framing this issue incorrectly. This is an economic issue, not a military issue. What matters here is economic power. Further, it is not France that is demanding influence but the EU (as well as China etc). And guess what, on the economic front the EU is quite level with the US.
Looking at recent economic conflicts, you see that the US has not been so successfull. Not so long ago the US lost a case of export subsidies at the WTO - the EU imposed a couple of billion in import fines on things like Harley Davidson bikes. This didn't last very long, because the US quickly caved in. In these conflicts, military power is futile.
So the big question is whether the EU and the US are willing to let the control-the-internet standoff escalate into a full-blown economic conflict. I think not, it's not that really important. Here's my prediction: some sort of limited influence-sharing agreement will be made, possibly as part of the current negotations of agricultural subsidies.
in MySQL, the statement REPLACE INTO will perform an update or an insert, depending on whether the primary key value exists in the table. It performs exactly like your WRITE command would.
in MySQL, you can perform a SELECT LAST_INSERT_ID() to get the last inserted value. in MSSQL, use a SELECT @@IDENTITY to get the same. (check in the docs whether you need @@IDENTITY OR @SCOPE_IDENTITY or the third version, I always forget).
That is an obvious reply. But think about it. How does that explain the sudden rise in CEO salaries, relative to the 'normal' salary? Do you really believe that the supply of Top Quality CEO's has been steadily dropping for the past (say) 10 years? Why would it?
Besides, the fact that the amount of qualified CEO candidates is less than the amount of candidates does _not_ imply that the supply of qualified CEO's is tight.
If that were the case, the high salaries should be explainable by a lack of supply right?
But that doesn't make sense. Why would the supply of people willing to be CEO be so tight? Hell, wouldn't everyone be willing to be CEO?
Since CEO salaries have risen relative to 'normal' salaries in recent years, you would even have to explain why the supply of CEOs has apparently become even more tight in recent years.
What I think happened is that the rise in CEO salaries sparked a 'me-too' spiral in the corporate boardrooms. Somehow, at some point a link was established between high-performance and high-pay. In other words, the amount of pay the CEO received was supposedly linked to his performance. All fair, you probably think.
But what this means is that if the CEO of a comparative company earns more than you do, you by definition are not a good CEO. That reflects bad on the company, since the shareholders demand that your company is run by the best CEO in the world. In other words, as soon as the pay of a comparative CEO rises, your salary must rise as well just to signal to the outer world that you are still a top-notch CEO. A never ending spiral is born.
Does that mean the unit tests would be readonly for the general public? I'm assuming they should, since otherwise you'd just delete the unit tests if you wanted to check in some faulty code.
But what if someone changes an interface and the unit tests need to be updated?

because disk reads go up to twice as fast (if you're running a mirror that is). writes obviously don't go any faster.
this was predicted from the introduction of the euro though (didn't bother to RTFA, maybe it already mentions this). The largest euro bill is worth more than the largest dollar bill, so you can pack more value in a suitcase of euro bills than in a suitcase of dollar bills.
Presuming you have enough language skill to know that "create" is not equal to "develop, nurture, and improve", which country did create it?
I think the GP meant that no country singlehandedly created the Internet. In case you hadn't noticed: the whole reason this topic is so interesting is because people from many different nations are sharing their viewpoints, thanks to the global nature of the Internet. In other words: if the Internet weren't international, it wouldn't be as valuable to the world as it now is. We created it together.
The US created the the Internet, and there is no question about that. It has been at the core of it from the very beginning.
I respectfully disagree. And unlike your completely empty claim, mine actually contains information. The WWW (remember, that stuff with HTML) was invented at CERN (*). Where's that? Switserland.
Interesting read, thanks. FYI: Europe is not a country. It is an oversimplification to consider the european countries as one. More importantly, it makes you look like yet another ignorant American. That's a shame, cause apparently you aren't.
your analogy is flawed. any official agency will issue some sort of official ID card. You can verify the ID by contacting the agency (of course, make sure you independently obtain the correct telephone number, etc). This way, you are able to establish the authenticity of the person at the door.
the whole point of this JS flaw is that you can't establish the origin (identity in the analogy) of the popup.
So from the fact that MySQL lacked subquery support you derive that there are a lot of bad programmers? me thinks there is only evidence here that you're a bad logician. Now that is a skill a good programmer must have;). A couple of remarks:
- if you're building a simple website, chances are you won't need any subqueries. Websites were (are?) the bread and butter of MySQL.
- the fact that the dbms lacks subquery support does not imply that the programmer lacks knowledge about them, nor does it imply that programmers generally use unnecessary db connections or queries!
- The MySQL manual states, correctly in my opinion, that in many situations subqueries can be rewritten to joins. Could it be possible that all those bad programmers out there were aware of this and you weren't?
yes, but the alternative would be to admit it wasn't a negligable error by the employee. That would confirm that the manager himself made a mistake by risking five production stations with untested software.
So, rather than take the blame himself he covered his ass by firing someone who wasn't the real cause of the problems.
He kinda defeated the purpose by publically admitting it was his own fault though:)
If you're still inclined, take a look at "Agile software development" by Cockburn. He's not telling you to abandon all design. Instead, he claims that you should not perform any 'overhead' activity if it isn't needed to get the job done. So if the complexity of your project requires you to plan a design phase, by all means do. But, if you're in a project where you can go ahead succesfully without performing an initial design phase, then don't! It's as simple as that, really.
according to the original story, someone who was doing paid work for OSDL (Linus' employer) was reverse engineering the bitkeeper client in his spare time. For bitkeeper, this meant that OSDL was indirectly funding the creation of a free bitkeeper competitor, which goes explicitely against their license terms.
It may not have been the nicest thing to do, but you can't really blame them for protecting their investment can you?
