When requesting hardware for a WebLogic server, what hardware would best improve its performance? Should I give it lots of memory, CPU, fast hard drives? The OS is going to be Redhat 4 either Standard or Enterprise.
Memory is cheap. Give it as much as you can. 4 gigs is what, $50?
Depends on the applications you deploy on it. It's impossible to answer, given that we know nothing about the apps deployed, the hardware you have, and the myriad settings available on a typical Java EE app server.
More is always better. Supply the most memory, the biggest hard drives, the fastest multicore processors you can afford.
That of course depends a lot on what type of applications you run on the server. I know that our WebLogic portal eats quite a lot of memory (10+ gigs) while other apps make due with a lot less.

From experiences with process monitoring in Ruby, what do we recommend as the best process monitor. These are some of the features I'm interested in:
Efficient memory management without memory leaks
Monitor processes that are consuming a huge amount of RAM and automatically restart them
Optimum up time i.e automatically restart processes when they die off for some reason
Easy debugging i.e the process should still be able to log to a log file
I have used Eye gem now in one of our production apps and it's been running for the past 3 years. We haven't experienced any memory issues with it, although, we don't do heavy computational task with it.
Eye was inspired by God and Bluepill. So far, I haven't experienced any memory leaks with Eye. The eye process itself is super light weight. Uses just about few kilobytes of memory and less than 1% of CPU.
You also have various features with eye such as easy debugs, memory monitoring for processes, cpu monitoring, nested process configuration, mask matching etc.
Eye is awesome, I do recommend it.

I recently had to enable VT for windows7 since I want to run ubuntu on vmware so I was wondering why isnt it enabled by default is it some kind of security issue or just not necessary for the average user?
There are several reasons, including "security" and "performance":

Intel virtualization technology can get hardware intensive and although the software requirement is low (Windows Vista) only modern CPUs made by INTEL ONLY such as Intel i7 support it.
Not all windows computers have an Intel CPU though (a good amount of them do). The only people that use the VTX technology are developers and people who want to run a different operating system than their computer came with, so not everyone. As for security issue, I'm not sure but it can get very RAM intensive. (i.e. the Android HAXM for developers has a default RAM usage of 2GB, and the minimum is 512 MB!).

I'm looking for a shell where I can test shellscripts and a programs on a Mac.
What I'm looking for, is something like bshellz.net but with Apple computers (i.e. Macs). Is there such thing available?
I was googling for the last few days, but I couldn't find anything.
If you are developing a free software (open source) project, you might be able to request access to the GCC compile farm, which appears to include at least one Mac Mini.
If you're not developing free software, it might be harder to find people willing to donate their CPU and bandwidth to you for free, especially since Mac hardware tends to be a bit expensive and Mac OS X is difficult to virtualize unless you pay half a grand for Mac OS X Server. There seem to be a variety of places which offer colo or dedicated hosting for Mac Minis and XServes, but not a lot of people providing free or cheap shell accounts on shared servers.

Any idea for TIPC protocol on Windows systems or any similar protocol which is available on windows ?
Thanks
Arpit
The Wikipedia basically says it's general-purpose communication library.
If you're designing an HPC cluster, take a look at "Microsoft High Performance Computing" in MSDN: http://msdn.microsoft.com/en-us/library/aa496121.aspx bot keep in mind that API only exists on some editions of their server OSes.
I think you'll only get better answer when you'll describe what kind of tasks are you going to accomplish.
P.S. I don't actually get the point of TIPC, even after reading the programmer's guide.
It seems using the API is not easier then using sockets.
But when you're using sockets, at least you've got tons of good books, online manuals, and easy to use debugging and diagnostic tools.

I'm looking for a web application to manage tasks (not necessary programming-oriented) for a small team. It must be easy to setup and maintain, and I don't look for an SaaS solution. It must offer file upload and mail users in case of a change. There is hundred of solutions available but most are too complex for what we want or are not "stable" (not updated since a long time, not very well programmed). i was wondering if stack overflow's folks have some recommendations...
Try:
lighthouse - http://lighthouseapp.com/
-or-
gemini - http://www.countersoft.com/home.aspx
We had a very similar requirement and after much searching we eventually decided on Redmine.
Does all that you require and more. Setup couldn't be easier if you use one of the Bitnami stacks. We went down the virtual image route as we had a VMWare server - but installers for existing platforms are also available.
I tried Basecamp some time ago but I don't need a web based solution. But it was pretty good.

Redmine is a great project management, used by many open source projects. It is also quite actively maintained and really stable.
It's worth mentioning that even though Redmine is software oriented, it can easily be used as a project management software. All you have to do is ignore all the parts about repositories and you have a full-fledged project management software.
