Voted first thing this morning... Based on the number of commercials running in Ohio, and the tight margin between the candidates, I've been watching the news online expecting to see some controversy start brewing. Fortunately, I've been disappointed thusfar.
You're right... I guess I didn't really think about where the money would come from. But, if anyone has any really expensive hardware sitting around that isn't flying off the shelf the way it used to, I would think it would be Sun. So, maybe they could put some of it to use building a cloud of their own. I've just always been of the school of thought that if you don't like how something is built, build your own.
Ahh, the ol' buckling spring... You can still find them if you look (http://pckeyboards.stores.yahoo.net/). There's nothing like tactile + auditory feedback when typing:).
The answer is "no," but for a different reason than what you may be thinking. Certain language features have been introduced recently that are used in these draft specs. For instance, for Servlet 3.0, one can configure a servlet with annotations (rather than configuring in the web.xml). Annotations weren't introduced until JDK 1.5. So, the JEE spec isn't tied to a specific JDK, but the JDK you choose at least needs to be able to support all the constructs referred to.
I guess that's one way to look at it, but IMO, as one of the struts developers, I was happy to get easy access to copies of their OS so that I can virtualize them and test across browsers, etc. You can say it improves their product, but I say it improves mine... TOE-MAY-TOE / TOE-MAH-TOE however you want to look at it, I appreciated it.
Although it is nice to see code donated, they made a much bigger contribution earlier allowing all apache committers access to MSDN. This is full d/l access to all of their products for testing, etc.
whereas big power plant generators are 1000 MW or more.
Heh... that's it? I once heard of a professor somewhere that was able to build a portable generator, small enough to fit in the rear half of a small car, capable of outputting 1,210 MW...
Nonsense. Do you understand what the output of such a generator would be?
I believe it is very high voltage with not-so-much current. Well over 100,000 volts.
The separation between the output terminals would be larger than the space occupied by the car.
OK, what if I'm wrong and it is lots and lots of current. At 1200MW the output current would require something that isn't going to fit in a car to connect to the output terminals.
Either way, it isn't fitting in the space of a car. Not even an Excursion.
Okay, come on, are you kidding me?! You really didn't get it? It could be one of the most popular movies of the 80s! It sort of ruins the punchline when you take it serious. BTW, I revoke your nerd card. Maybe you can earn it back if you go rent the movie.

The OpenJDK is Sun's JDK, only under the GPLv2 license. Sun's JDK may make the source available, but you are limited as to how you can re-distribute it or derivatives of it.
Makes a bigger difference than we realize. Sort of makes you wonder how many other smaller projects don't make it because of a poor name. I hate coming up with a name for anything I work on... Heck there is times when I sit and stare at the screen because I can't think of a good name (that will get me through code review).

My guess would be "no." Based on the FUD that they periodically push about open source, I'm guessing they would want to add support through a project of their own so that they aren't "infected" by the "viral" open source licenses.
IMO, what makes this market tough is the saturation of competition + the low QoS of home broadband. I had lingo for a while until I eventually moved to the cell phone only setup. I was hoping that VoIP would drive the price of land lines down, but it does not seem to have phased telcos and the cable company VoIP offering is nothing short of highway robbery.
To me, the appeal of a movie is seeing it, not seeing it over and over again. If a friend has a movie I'd like to watch, I'll borrow the DVD, watch the movie and give it back to him. Even the movies I like, I can't see myself copying... Now my kids on the other hand... Put it this way, if I have to watch Monsters, Inc. one more time!!!!
As a somewhat-successful professional software engineer, it has been my experience that this sort of programming is not as common as many students and/or civilians think. The majority of programming code is done on the business level... i.e. I need a report that will tell me how fribble relates to frabble, or we need a system that will track all of the incoming support requests on our jimble jamble product.
As a student I really thought I would get the opportunity to write games, but after seeing the development process at a software publisher specializing in gaming, I realized that the programmers spend more time dealing with things like physics and optimization and leave a lot up to graphics artists.
Based on my experience with their agreements, I would imagine that they are cost-prohibitive to most small businesses. Their volume licensing agreements like Open Licensing (http://www.microsoft.com/licensing/programs/open/ default.mspx) are really meant to give customers some peace-of-mind when managing a large deployment. This program is meant for organizations with less than 250 workstations, but I can't see anyone seeking this sort of agreement unless they have over 100.
What I would like to know, is how reliable this can be when only surveying 61 people. I mean, I know that statistics can be wrangled just about any way you want, but it doesn't seem to me to be very useful to ask such a small number. Before getting my hopes up that M$'s poor performance is finally being noticed by businesses, I will wait to see how their sales numbers look the next few quarters.

Don't get me wrong, bad database design is bad database design whether it is ORM or any other technology. Something tells me that based on the average row size of 9KB, I'm thinking this table does not really follow good relational design principles (1st normal form, I'm guessing). I've had a project where the data grew quite quickly, quicker than we had anticipated and the database needed optimized. Fortunately, since we were using Spring backed with Hibernate, we had interfaces defined for all of our persistent objects. Our solution was to use iBATIS to get some more granularity with our database queries, build some stored procedures (so that the query plan would be compiled) and add an index or two. The iBATIS classes were retro-fitted to implement the interfaces for the hibernate objects and then all we had to do was tell Spring to use the iBATIS objects rather than the Hibernate objects. Surprisingly, all of the unit tests passed and post-install, we increased our performance quite drastically. The whole project went as smooth as you could hope and I was pleasantly surprised because I really didn't think it would work out. I've been a fan-boy ever since. I still start with hibernate because it does help cut-down the design time, and I believe that "premature optimization is the root of all evil" (Knuth)

After having used Object-Relational Mapping in Java for a little bit, I really think that it should be adopted more widely. Prior to using Hibernate in Java, I stood by the notion that CUD operations in the database should strictly be done in stored procedures. This notion seems to be going away, not just for myself but in the industry as a whole.

As a parent of a child that *really* wants a PS3, I can say that the price has been the biggest barrier. It's hard to justify this sort of expenditure for a twelve-year-old... I sort of feel like he'll grow up like his gaming-geek old man if I give in and buy one. I'm glad to see that they are coming down in price.

Well, If I'm advocating monoculture, then this advocates close-mindedness. You are missing my point entirely. You can't possibly have evaluated every single Java Web Framework. I know you can't because it is not possible. You are depending on the community to do that for you. Personally, I prefer to find out for myself. You jump all over my case because I think there is too much choice to make an informed decision. You are insisting that you have made an informed decision, but I'll bet that you haven't evaluated (read used) more than one or two major frameworks.
As for your assumption that I work at a big company with rigid requirements. Not right now... I own a small consulting firm and I work at the family business. Both less than 50 employees. Before that I worked at a large firm, but it was not a rigid environment. In fact, we were considered CMMI level 1. My opinions come from evaluating the situation and seeing what works well and what doesn't. My genuine case for "too many" cases is this... You suggest MyFaces + Tomahawk. Now, I am going to ask have you tried RAJAX? https://rajax.dev.java.net/
Each time you respond, I am going to either point out that you didn't give the suggested framework it's proper attention, or I will suggest another framework to look at. My guess is that you will eventually give up. Now, as far as big companies with rigid requirements... You strike me as the sort of guy that has trouble working on a team, quote - "Yes, because it is my call." Would you really have a problem if I were your team lead and we would have the following argument - "We are going to use Struts2 for this project," you - "I think we should look at other frameworks like MyFaces + Tomahawk," me - "I appreciate your enthusiasm, but right now there are just too many frameworks and I would rather move forward than spend the next few weeks arguing over which framework we'll use." Are you the type of person that would become unproductive and spend hours complaining to other team members about the team lead not listening to you? It sounds like what CMMI people call the "hero". It's not meant as an insult, heroes are considered very productive at most organizations, but managers with experience running teams of developers are beginning to work out practices to eliminate that sort of behavior.
Also, when I mentioned that the decision of framework should be made by an architect... Well, if your projects are so small that you want to bang them out and get them out the door, why are you using Java? Why not Ruby on Rails? Seriously, Java is great, but for quick projects there is a lot more overhead than just about every other platform out there. Now, if you are working on decent-sized projects that require regular maintenance and service thousands of people per day, then someone should be helping to manage the technology to keep projects somewhat in line so that if SystemA at your company needs to talk to SystemB, then it can happen with little effort. Whether that person's title is architect or he is just one of the older fellas who has been at the company a long time. I have personally been a part of projects where two vastly different technologies were required to work together, in one case, we had to make a Java web-app talk to a custom, non-standard server (http://www.aolserver.com/). Bad architecture leads to more work. If you're in one room deciding that MyFaces + Tomahawk is best for your company, but in another room someone is deciding that Apache + mod_perl and perl's CGI module are the best thing for your company, then I'm glad I'm not you when management decides that your projects need to be integrated.
So, anyways... Tell me what you think of RAJAX, then when you're done take a look at SEAM, and if you have time left when you're done with those two, read my website for information on Struts2 (dig, dig, wink
