I often see hyphens for the name and value in my HTTP response headers, perhaps in place of content-length header. I'm testing with Apache 2.0 (IBM HTTP Server 6.1) on windows.

Is this just a way or Apache deleting a header it decided not to use, or does it represent something more significant going on?

I ran into this using IF001, and cleared the error by doing something like Project - Clean, and then forcing a rebuild. Will post more if it comes back.

I don't know much about preparation for game development, but ran across this, which might offer some leads.

The payoff in a more advanced education isn't necessarily short-term. Education and experience are in some ways complementary. As you gain experience with technology, business, and organizational culture, you will find more places to apply things you learned and the insight you gained from learning those things.
I suspect that over time, you'll earn more than the average person with less education because you'll be able to better with more things that are important to the business. You will find some people who didn't finish high school but can run circles around you; education isn't the only way go learn and develop insight. But if you focus on doing the job and learning whatever you need to do the job, I thing you'll find that your education will serve you well over time, even if you start off with less pay than someone with much less education.
Another thing to keep in mind is that many people with just a few year's experience entered the job market when demand greatly exceeded supply. Now, in many cases, supply greatly exceeds demand. I hear that this has resulted in some pretty big changes in hiring pay. People who stay in their jobs are usually less drastically affected in the short run than those who take a new job, especially a first job. However, things tend to even out over time.

at java.lang.Thread.getContextClassLoader(
at org.apache.struts.util.RequestUtils.applicationClass(

Is the struts library being loaded from the usual place?
It looks like one factor here is that the context classloader for the thread is not a "child" of the classloader of the struts package. See the API documentation for Thread.getContextClassLoader.

You are going to be reasonably well equipped to learn a living whether you have BSCS/MSMath or BSCS/MSCS, or just the BSCS for that matter. My bet is that you'll be happiest long run by following your interests. If you are interested in getting a math degree, there is a good chance you will be happier working for someone who appreciates the math degree than for someone who doesn't.

Yes. But the rest looks more like COBOL.

I've not gotten to do much programming. But when I have, I've liked to have a way to feed what I learn week-by-week back into the process as things go on, and to adjust things to keep the effect of misjudgements or the zillion little things that sneak in under the radar from piling up into the part of the project. As you work a project you usually develop a much better understanding about which features of a project are really important to the end user, which are costly to develop and to use, etc. This, coupled with progress information, could be adjust priorities, assignments, and estimates, if anybody had the time to think about it. It seems to me that schedule feedback when there is time and opportunity to do something with the information could be greatly appreciated, especially if it helps avoid the death march. "Padding" at the beginning (meaning trying to allow for details that are not explicitly in the plan) is helpful, but I suspect that continuous feedback and adjustment to the plan gets people to think a lot harder about what they are doing and how they are doing it.
As for charts with red on them... A lot would just depend on the tone of an organization. I've been very surprised at the degree to which "non-management" reaction to change is "this too shall pass". (I shouldn't be, since, all too often, it is true.) You might want to consider whether your gut reading of the environment is "we are all trying to learn to do this better", or "what we had was just fine, let's not rock the boat". Almost anybody is going to first turn red when they see red on their task. So what matters is whether people get stuck there, or get past the pain and on to how to solve the problem. Pushing past that pain is a learned behavior. [M. Scott Peck, The Road Less Traveled.]
My hunch is that, at best, it will take more than a modest increase in hours work to move from "delivering whenever it is ready" to "delivering on schedule". This leads to the problem that, whatever you try, if people didn't really buy into it, the one thing they will know at the end is that "it didn't work".
Sorry to give you a hard time on this. I know it is a tough problem, and I wish I could be more constructive. I'm glad I'm not a manager.

Perhaps it would depend whether the timelines came from the programmers, and they have the ability to adjust priorities to get the task done, or it is just another way to be beat over the head with someone else's idea of reality.

Here are the prerequisites for WebSphere Application Server.
The Library link on that page will take you to a page listing lots of documentation. The combined online InfoCenter puts a lot at your fingertips. The WebSphere Domain at provides access to some good free books, as well.
Installing on Windows can be as simple as running setup (as I recall) from the install media, once you know what you want to install, and that you have a suitable environment.
There are other "WebSphere" products besides the application server, e.g., Studio and Portal, to name a few, but the mostly build on are are closely related to the Application Server.

Where does it say anything is special about Sunday. Do you mean Saturday?

Perhaps the site from which you downloaded those files has information on what they are.

Check the InfoCenter for the detailed requirements for Portal 5.0.
The Enterprise Version of WAS includes PME, the base version does not. PME provides APIs that Portal requires.
I wonder if the reason you are not running is that you don't have PME, just base. I think base is always there, but for an enterprise install, PME is there as well.
I somehow got the idea that if you start the Portal install on a system with no WAS, it will install the necessary WAS for you, at least when installing from CD images.

The signed document officially announcing that you were awarded the degree is called a diploma. However, some diplomas announce something other than the award of a recognized degree.
