- handling 10.000s of files in one "release" very very quickly - "change-set" oriented (change in more files as single transaction) - support for off-line repositories and easy merging up - no big stress on handling binary files (the aren't many in Linux kernel) - easy work with many many (10s) of different versions of single "file tree" with easy solving merging conflicts (imagine having linux-uml, linux-acpi, linux-sata, linux-real-time etc. trees)
Does anybody have some example of real (non-scientific nor SETI) example of usage of such a cluster? I want say - what kind of job can such a machine do, especially if generaly network latency/throuhput sucks (standard is still 100 Mbit).
- How recharge batteries in the middle of battlefield? - What about wind? Make war only when no wind? - My got - why do they test this on for the NAVY? I'm pretty sure, that range sucks (compared to old, but still usefull device called "radar"). I can imagine this usefull for street fights

Of course that having security bug in user-space program is problem but it's not so critical as bug in kernel but still critical enough. The issue is that if you care a bit about security, you can easily avoid this ~/.profile hack - just use full paths and you are 100% sure that you'll not use the trojaned version.
Show me some user-space program in Linux, which could gain you root? THAT's the main reason, why UN*X are generally more secured then Windows - absolutely clear separation of user rights. In Windows there lot of SW has to run at insanely high priorities so any bug in them leads in machine hacked. In Linux if there is bug e.g. in Mozilla, all it can do, is delete your documents but can never "attack" any other installed SW. Of course - there are some setuid SW in Linux, but there are only very few and they don't evolve much (no new features+bugs;-)))
Yeah, but how do you balance the KDE applications - do you only load-balance (start & run application on "random" node) or you can migrate and/or duplicate (for fail-over) processes?
Hi, could you post (maybe to email - this is getting a bit off-topis) some more info? What FS do you use? (OpenGFS from Sistina/RedHat?) How kind of KDE applications and how do you balance them accros nodes? Thanks.
I'm doing now some development with print drivers so AFAIK that it's:
(pdftops/html to ps/a2ps/...) -> ghostscript rendering using print drivers -> printed page
(note - I don't know what is ghostscript calling but I don't think that any external programms) (note 2 - at least this works when you use HP PCL drivers)
And there is still LOT of non-PCL printers out there and they are still selling (high-speed dot-matrix printers, thermo printers, special application printers (barcode cards etc.)....)
Why can't networked filesystem/LDAP/SW distribution & upgrade etc. etc. use single SSL library to encrypt everyting? (just example) - once you do enough (10s of) security audits, the probability of critical security error should be near 0%. But if every layer will use "invented here" security negotiation/encryption/hash... the more possibilities that you'll use something with forgetten security bug...
What kept UNIX relatively free from exploits is that GPL code prevents most of ppl to publish "ugly" code with some really really dirty security hacks (at least in the critical parts of OS) like "ActiveX" in Windows...
- PS you can very easily convert to PDF - none for PCL! - there tons of tools which enables you "4 pages in 1", accounting quotas etc. etc. - none for PCL! - try to display PCL file - WHICH PCL? PCL5? PCL3?...
There is simply NO reason to give up - tell me one single argument (except VERY slight speed-up) which will balance the loosen flexibility and necessary to rewrite all existing tools (CUPS, print drivers etc.)
I really like the idea from the article - what's wrong with UNIX is that it's great stand-alone system but once you connect lot of UNIX machines, it's hard to get "all-over-network" filesystem/accounts/desktop enviroment/SW distribution & update/etc. - I know that there are solution for every single thing of this BUT it's always "non-standard" (compared to "stand-alone" UNIX machine) and not-well cooperating solutions...
Why not allow more non-profit organizations to test new satelites technology? And not some nano-satellites with 30 minutes life-time. But something like highly-experimental device... It should be 23 ton payload - that's LOT of experiments;-)
Just some info about Ronja - it has inspired a lot of similar projects in Prague (it's all developed by quite small group of ppl in Czech Free Net - www.czfree.net) and there are already running some prototypes of Ronja or derived (non-GPL) projects on 100 Mbit optical data link!
Unfortunately, main Ronja HW developer - Karel Clock Kulhavy - is very "hard to communicate" man...

Linux is so far stable and quick also thanks to the "no binary driver API". There is NO (read "NO!!!") reason for your driver to be closed source (maybe except ATI/nVIDIA which are doing some crazy optimalizations - but hell, why don't they devide they driver into open source (2D + basic 3D) part and binary (gaming 3D)?)
I wrote at least some code in: Bash C/C++ Delphi i386 ASM Java Pascal Perl PHP Prolog Python Ruby Visual Basic
So I have some experiences. But I see this also all around - I'm managing also 5 other SW guys and those who write in Perl produce really unmaintable code while the same ppl in C/PHP produce really nice code (when run through indent;-)) - I know this is very small sample but I haven't seen on my eyes any large project (maybe except/.;-))) written in Perl...

Yeah - that's the trick! Almost nobody will use full 1 Gbps capacity BUT it sounds cool to have it :-)

How they want to prove that the person that looked at the "papers" was the "accepted one"... (if they didn't posted it all over blogs ;-))
There are many ways of telling the truth - other then lying....
FUD on the horizont, sirre ;-)

No PCL!!!! Reasons:

- there tons of tools which enables you "4 pages in 1", accounting quotas etc. etc. - none for PCL!
- try to display PCL file
- WHICH PCL? PCL5? PCL3?...

But you can say that microwave has also some kind of feedback
