Are there any alternatives to the Open Source Job Scheduler?
I'm looking for a way to gain more control over scheduled work tasks than plain cron is offering, but haven't found anything else but Quartz, which isn't language-neutral.
There's JAMS. http://www.mvpsi.com/JobScheduling.aspx
Especially awesome if you're using OpenVMS
We use JAMS as well but it's not cheap. When I hear "open source" I think "free" and JAMS is far from free. My boss negotiated the agreement so I don't know all of the gory details but I know we spent in excess of $35,000 for JAMS
By the way, I should mention that it is a great tool and their support is awesome
I'm not sure from your question, but I think SuperScheduler could match your requirements:

I can't imagine what do you expect from it, if you want "task scheduler" than you probably want to specify interval and task itself. that's exactly what cron is for.
Someone mentioned JAMS on OpenVMS. We use JAMS on Windows with UNIX and Linux Agents. They have a Cron converter as well which is not perfect but it does about 90% of the work moving Cron jobs into JAMS. website is jamsscheduler.com and jamssupport.com

Having a program that has several distinct parts is usual.By part I mean a graphical part that has its own windows and functionalities.(About non graphical part, I think creating a library is the preferable solution)
How do you prefer to separate them ?
Is it better to make each of them a static library and use them in the main program?
Or the better solution is to create an executable file of each one and load them in the main program?
Or even better solution?
I suggest that you read Code Complete or something simlar. This book and others go into the best practices or even how to know which of the best practices you should look into when you create a product.
The problem is one of scope. You need to know your specifications and the parts that join together, as well as which design practices you are going to use before you can answer this question.
I am also inclined to think that there is no right or wrong answer (depending on HOW wrong you are) and that no-one else can answer that question for you, especially since you are likely to be one of the main players in maintaining the code.
Hope that gives you some food for thought :-)

As a programming novice, I often run into trouble when trying to install packages, use virtualenv, and basically do anything even mildly complex using the command line.
What are some good references out there to help me UNDERSTAND things like my path, environment, shell scripts, etc?
Basically, I'm tired of copying and pasting. I want to really understand what's going on.
Thanks!
I used Linux in a Nutshell by O'Reilly. It helps you get past the initial beginners stage. Obviously there are a ton more links and tutorials, lists of keystrokes online, easily found with a Google search, but this will help you get going, and nice to read when you are on the bus or at lunch or whatever, to give you some ideas you might not just happen on in normal everyday life.

Is it still possible for someone to learn and start contributing to the linux kernel? looks like the contributor list seems to be dominated by paid employees from large companies. Is there still a chance that one can get their patches or bugs in the kernel or is it sort of saturated with great developers? I'm thinking on focussing on the networking subsystem. Sorry, if all this sounds too noobish, but any opinions on all this? Is it even worth it to start on this route? I plan to spend my evenings and weekends for however long it takes, assuming I will be able to make some contribution.
Thanks.
Yes. Example: Con Kolivas (of course you could also cite that in order to give arguments against hobbyist development). See also this survey (original source):
For the evaluation period, almost 19% of changes were reportedly contributed by unaffiliated hobbyists.
Write something interesting and relevant, head over to the mailing list (or vice versa: Ask if something is interesting at the mailing lists, then head over to development). Not even the head of development Linus Torvalds is looking at your professional status.

Urgently want to know best UML designing tool in Linux?
Which Also Support ERD
Is it Possible to use in NetBEANs IDE 6.9.1
Almost all UML tools are Linux compliant.
Try Papurus with Eclipse or BOUML which are free and open source. RSA is pretty good as well as Omondo but not free.
I use and prefer Umbrello.
ArgoUML is also quite good but its GUI bugs will drive you mad...
I never had any problems with dia. It's part of gnome, almost all distributions package it. Also has a Windows version but I didn't use that one for a long time. Of course, "best" is relative to what you are expecting from it.

I want to work with the Linux kernel, but I have no idea where to start. Is there a sort of ticketing system somewhere where bugs and such are distributed? Where can I get ideas for potentially useful contributions?
EDIT: Yes I know what I'm doing. I've been writing my own modifications for a good while now, and I'm doing an independent project under one of the operating systems researchers at my university next semester.
The reason I ask is I'd like to contribute my expertise to the dev process, and I don't know where to start in terms of organization. In terms of technical matters, I'm just about there.
Start with these: Kernel Bugs involving typo.
(Search everyday until you find something promising).
Search that bug database with keywords like "comment", "typo", "documentation", "minor bug", etc.
Also, search under the category Documentation here.
Learn the process first. Then, attempt to contribute something significant.
Pick a subsystem and subscribe to the relevant mailing list. Spend some time studying the subsystem. Start small and fix simple bugs then gradually do work of higher significance. You may want to look at the TODO files in the kernel source directory, especially for drivers in staging.
