For my first release of my kernel I plan to finish my Memory Manager(this includes Paging, physical/virtual Memory Management, Kernel Heap Manager), the Class-/ObjectManager (something like the VFS on POSIX-Systems, but much more sophisticated(e.g. objects are instances of classes and classes can be inherited and you can even do polymorphism with them.)), then there's multitasking which will heavily interact with the ObjectManger, a basic shell would be fine too.

Maybe this helps .

Well a balance of all 3 is good. If it has loads of features its a definate bonus, but if it takes 5 minutes to boot and is too slow to use, whats the point having them. Likewise if it keeps crashing, it becomes unusable.

MS-DOS shell ftw.

Well its up to you, if you need help testing then you should probably release on betas too

What do you -mostly- prefer in hobby operating systems: stability, many features or speed ?

Stability and speed.

As you know I'm not a big fan of POSIX-looking operating systems , how should be the interface, for example shell? MS-DOS style? Black on white? POSIX-looking?

POSIX-looking. MS-DOS's shell is very limited. Hard to do anything with.

Should the first release of my OS be multitasking or singletasking?

Multitasking, if you could.

Should I release only fully stable versions (sparsely) or alpha, beta versions (frequently) ?

Alpha and beta!

I'd have to agree with Jeremiah Griffin. Release often!

I'll try to release Patlock more often than PortixOS (for users not from OSdev: it seemed like vaporware). No release dates: "When it's done." - Duke Nukem Forever release date, 3D realms

I'm planning to do the shell in FreePascal, kernel will have a rewrite since "DexPortixOS", but it will stay in ASM. Also there will be some internal programs hardcoded to the kernel (cmos password wiper, FASM etc). I'll try to use NTLDR as the boot loader... or it's alternative from reactOS project.

What hosting do you prefer? Google pages? @JamesM: Yurx.com? ... Was the original "xf.cz" okay? It had some glitches, but I didn't knew if it was working overnight (aka afternoon and evening in USA).

Google code is good, it gives you an SVN directory...

Google code for a closed source kernel is no good, is it?

Ah, closed source.......special.

W/e

its fine for closed-source, but anything uploaded has to be GPL, LGPL or BSD (iirc). So you can just keep the source offline, and only upload binaries you are going to release

So - essentially, you're keeping your source closed - but releasing the binaries under a permissive licence?

I don't believe that was Google's intention, but... clever.. I guess.

Hosting will be at wz.cz, I tend to create the OS page in a wysiwyg HTML editor and I try to keep the site as simple as it gets. No dot.tk domain -> it's just not worth it and everybody knows .TK is lame alright.

There will be two language versions, Slovak and English.

The OS will be written from scratch, programmed in Freepascal.
Development starts from: 02.05.2008

UPDATE 02.05.2008 19:20
Created patlock.kx.cz
UPDATE 02.05.2008 19:35
Too much ads and slow service, switching to http://patlock.xf.cz

cool more closed-source OS's ... may I ask why exactly you are keeping the source as your own?

I think releasing betas would be worth it, but alphas should be kept to yourself as they are just that, a pre-beta, something that is probably too buggy to be functional.

Also, I would go for speed and stability, break out the efficiency algorithms =).

This post isn't actually a OS test request, but I would like to have my site reviewed from you. You willn't find any downloads there, just comment on how it looks, if it's suitable, what shouldn't be there and especially grammar errors if you find some.

Anyways, here it is:

Cool your history, includes DexOS, good luck with freepascal OS.

PS: Have you seen the freepascal OS call "AnonymOS" ?
