Barrin's class is with her, I skipped it this semester because I just can't stand her teaching style. I seem to be an outlier though, everyone loves her. I'm hoping next semester a different teacher offers the course.

She was pretty cool to me last semester though, I got an 87.8 or something and she gave me an A for the letter grade. Pretty cool of her because she didn't have to at all.

That's not cool, it's grade inflation, and it's bull****. Basically steals from the students that actually earned an A, because it won't mean nearly as much.

Those other students won't know, and thus it doesn't affect them.

Besides, what you get out of school is what you learn, not what letter goes beside what class name.

Lot of people know about Java here!

I have some program I'm trying to use. The error is:

Invalid initial heap size: -Xms5g
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

I ran java -server -Xms4g

Got the same error

I ran java -server -Xms3g

Error occurred during initialization of VM
Could not reserve enough space for 3145728KB object heap

I can't run this much memory in my VirtualBox, so I'm using Windows7 with 6g RAM. I had to do this hack to get JVM server to run in the JRE:

http://stackoverflow.com/questions/1...server-jvm-dll

Any ideas to get this to run?

(rant: I hate Windows)

I think I know what the issue is. Windows is running over 2g of "stuff" and I don't know what it is. Even with everything shut down, it is well over 1g of "stuff," so it looks like I won't be able to run this program.

Is there any way to do swap memory on Windows so I can run this VM?

I had memory issues with my ****ty laptop, so I changed the default location of filepage.sys to my external HD and that fixed it. Not sure that'll fix your issue but I had like 80% of my memory just trying to run it at idle

Lol or maybe she felt that I did A level coursework and my final grade didn't reflect that. I don't see how that "steals" from anyone.

I tried to run an older version of the program. It ran into a whole bunch of deprecated Java commands, which I removed from the run script. Now I have this wonderful error:

Could not reserve enough space for 3072000KB object heap

*sigh*. I'm just not going to deal with it. The external HD idea sounds pretty interesting, but it isn't important enough for me to play around with the system (prepping for a job interview, but I can explain this one off, I think).

It could be possible to use a java decompiler to get the source if it wasn't obfuscated and examine the code.
If possible debugging the program, stepping through he code and seeing when the error happens by what execution of code.
Maybe you find that a certain feature, using x resources could be removed and it now runs with lower requirements.

This may be a stupid question, but are you using 64 bit windows?

Yes. 64 bit.

The Java is open source, but doesn't really do much. The other stuff is compiled though.

Doesn't the jvm need a continuous block or something silly like that?

I remember with some of the C++ projects I have worked on that launched a jvm for some external stuff, they sometimes would allocate the approximate memory needed just to free it again before launching the jvm. That seems to kick windows into shuffling the other stuff around to get a continuous block. Or something like that; it's a really vague memory.

Also double-check that you have a 64bit Java Runtime. (Plenty of people have 32bit Java installed on 64bit Windows fwiw, and there is a ~1.3G heap limit on the 32bit JRE.)

Edit: Also, what are you using for Xmx?

Xmx is set to 8g by default.

The program works by calling a bunch of Java load scripts to Jetty, then does whatever magic to get the rest of the compiled code to work, which is not in Java.

Assume you applied to a full-blown tech company. You send your resume into a unicorn-hunting job ad. They write you and invite you in for interview. No phone screen, no pre-testing. What's going on here?

Last time I went to something like that they offered me to come over and work a few months for free, but that's probably not a thing in US.

Yes, local.

First time I've had this happen. There was one other company that did it, but, but not exactly a tech company, though tied very much into tech. I guess that talking to a non-tech recruiter doesn't count in many ways, so I could say it has happened several times.

This one is a major moonshot. I have zero confidence going into this one, which makes it more confusing that they are just bringing me in. I think I'd last about 3 minutes in a phone screen, to be honest.

That's called an unpaid internship in the US.

Yea, that's a thing here too, but it was advertised as a job with pay depending on skill, which they didn't even test.

Fellow video game nerds,

Pretty awesome and crazy technical explanation of what's happening during the Super Mario World credits glitch, recently confirmed on console:
