Realtime OS Jaluna

rkgmd writes "Jaluna-1, a software component suite based on the respected chorus realtime os is now available in opensource (MPL-derived license) form. Jaluna, the company behind this, is a spin-off from sun to promote and develop chorus, and consists of many developers from the original chorus team before it was acquired by Sun. Chorus developed one of the earliest successful microkernel-based rtos's (could even run parallel, distributed unix in realtime on inkos transputers in 1992). Lots of good research papers here, and a link to the original newsgroup announcement."

Inkos?

Who are they?

Don't you mean Inmos?

When you go to the right University

[MosesJones]

I know it sounds harsh but the reality is that most courses worry about Java, C++, Jaluna and people become concerned about the technologies rather than the theories.

The person who knows Knuth will be able to code in any language, the person who doesn't is limited in what they can do. Did your course teach you how to dope a transistor, build an Op-Amp ? An AND Gate ? A Compiler for a processor you design ? An OS for that Processor ?

And did it do all of these by starting with theory or was the first lesson "Print hello world" ?

The problem with practical courses is that they teach people to be the bricklayers of the Software Engineering world. The theory course teach you to be the engineer and how to apply theory to practicality.

It isn't about being taught "cool" technologies, its about being taught the theory behind them. RTOS is great in that it teaches you about Thread-death, dead-lock, live-lock, IO blocking, race conditions in a very immediate environment, so when you build a bigger system you automatically avoid those issues because you understand what is the right way to work.

Some Universities do teach the cool theory stuff, but most people don't choose to do that as its harder. It also makes you less marketable in the first year after graduation as you don't have the buzzwords... 12 months on however you'll be roasting everyone.

Universities are supposed to keep pace--not have the attitude of "let's worry about all that new-fangled stuff later." If it means refreshing their curriculum every two years, then so be it.

Why? I'm a senior at the University of North Dakota. I keep hearing similar complaints from a number of people. The only really fundamental programming change in the last 25 years has been the introduction of objects. Stacks, Queues, Lists, Trees, networking fundamentals, storage and database fundamentals - the specific technology changes, but the fundamental computer science principles remain the same. Why should you get an education in whatever the technology of the moment is when it's probably going to be dead in five years anyway? A better education in the math and engineering principles behind these(and whatever the new technology is and whatever the old technology is) will serve you far better in the long run.

College isn't for technical training.

[BoomerSooner]

College is to give you a foundation of understanding so no matter where the technology goes you will have the ability to learn it due to your broad base.

If you want tech training go to DeVry/University of Phoenix (what a crock name). This is why a degree is worth more than certifications.

Plus, no one is stopping you from learning about RTOSes. I'm going through the Minix Computer OS Design book by Tanenbaum right now. You can either be spoon fed like most university students, or you can get up off your ass, show some motivation and learn it on your own. This is why I never have a problem finding a job and others cant get an interview. People want to hire motivated workers not someone who'll just tow the line.

Don't agree...

I left Uni with one programming language (Ada) (Okay and LISP, M68k, Prolog and other really useful languages!) one OS (AIX) but I understood however thing worked.

However the answer to the question "do you know X" is always "yes" the advantage to theory is that it makes the lie true. How long to learn a new language ? If you understand the theory then the only thing that matters is syntax, 2 days ? 3 more days to learn the libraries ?

You resume should say that at University you learnt the following, not "I taught myself" because employers will look for the former wording not the later.

Jesus though "Advanced web design" where you do Perl. What has the planet come to ? Sorry to sound like an old fart but "Advanced Web Design" doesn't sound like something in a degree, it sounds like a Dummies book. XML as a course ? Its a bloody markup language, what is there to learn ? XSLT ?!

Learning extra languages or technologies is simple if you just understand the principles. Then you can claim to have known them for years, even though it was only last week when you found out this interview required it. As long as you can understand the theory then everything else makes sense.... except VB.
