just googling to see if I could find anything. What about corkboard.me

or Linoit.com <-- I think this is not free not sure about ^^

Great! Thanks a lot for your suggestions! They seem so far to offer what I wanted. I hoped a desktop software that works offline would exist (as I've become a little paranoid after this incident with Icebergs I've mentioned) but I guess I'll be just fine as long as I keep a physical backup of my notes. :-) As for those 2 sites, linoit and NoteApp(which is the new name of corkboard) have both free and premium accounts-but the free accounts suit me just fine. I made an account on both sites just to be sure in case one of them gets discontinued or something.
Anyways, thanks again and +1 ! (Too bad we can't award 5 rep points in normal threads, but only in question and problem ones :-/)

I have some Navier-Stokes simulation software I wrote in Java a while back. Part of my interest in simulating natural phenomena. The NS smoke-bloom routine is pretty cool. Anyway, I can share the sources if that will help.

Why is it we park on a driveway and drive on a parkway?

you mean software that uses numerical methods for simulation and in java that sounds kind of cheap sim, from what i know for such simulation fortran or c++ is used?

Anyone know how to covert a .wps file to a format which the latest version of OpenOffice can handle?

It all gets turned in machine instructions before running, so it just depends what layer you want to code at. You could just as easily write it in BASIC for all that it matters, unless you are looking to maximise speed. My NS smoke-bloom code runs plenty fast in Java already, and in fact could use a thread sleep loop to slow it down.

I've written in FORTRAN and C++ as well. FORTRAN is optimised for writing formulae, but not necessarily for running them. In practice it is virtually as high-level as BASIC, and in fact much of the BASIC syntax was derived from it. C++ (and indeed most C dialects) are great if you want to write code that is almost 1-for-1 with machine instructions, but it is far from friendly. I've also written in Assembler, Pascal, Lisp, Scheme, Prolog, C#, Python, Perl, LOGO, and Icon. Each language has its strengths and weaknesses, so you should make your choice based on what you want to do and how you want to express that in code.


The general consensus seems to be this.

I didn't find an offline or plugin based solution, so if you are worried about document confidentiality with using an online service, you may have to look elsewhere.

that are some nice infos, (very shy) i have only experience with basics of c# not more. i assume you have studied physics or informatic?

because my basic question is about a strong (not weak) solution existence for the parametrised pde system called navier-stokes equations, your programm is just an algorithm of an numerical method for the n-s equations, i assume not even parametrised? so my question is from another science discipline, guess which? :)

Bits of both, though I am biologist by education. Mathematics is a hobby and passion. :)

Ah, I understand now. You aren't looking for specific Navier-Stokes implementations, but a generalised system for solving a whole range of NS equations, with various input parameters.

The obvious answer is the package, but that is insanely expensive for a regular user. However, I have heard good things about the [url=http://fenicsproject.org/]Fenics package, and it is open source. If you are strictly interested in Newtonian fluid dynamics equations, then this package might work for you as well. But if you are interested in things like wave propagation and solitons (as I am), I think Fenics would be the way to go, since it covers a whole range of formulae, and is custom programmable.

I am guessing you come from either an engineering or applied mathematics background. :)

EDIT: Fenics appears to be quite adept at handling PDEs, which is something you stated an interest in as well.

Why am I bored today?

if you are bored, i suggest to call the police and tell them, you're a terrorist, they'll get you some action!!

That's exactly my concern. Looks like I'll have to hook up my old computer, fire up MS Works one last time, and convert the files in question to .rtf one by one. Thank you anyway.

I did find posts saying the Libre Office can open these files, though there may be some slight formatting issues (mostly it seems to turn on Strikethrough for all the characters, but you can select the text and remove this easily).

I have recently switched from Open Office to Libre Office. Works basically the same, but the support and philosophy behind it seem a little better. It's free and open source too, being an OO fork.

I'll look into it as well. Thanks again.
