Windows :
Ok, looks like recent setup wizard are intelligent enough to not reinstall the same dll twice (or override a newer dll)
but if application A install DLL version 1.03 in its own directory and system has DLL 1.02, then there will be two dll loaded in memory, one for appli A, one for other applis using the lib...

Linux(and Unix) :
version number are part of the file name, which mean you can have several versions in the same directory without overrriding by error a newer version.
you can have,,
APP A can link with and so will use in reality
APP B can link with -> will use automatically
APP C can link with -> will use latest,
I think windows should copy and put the dll version in the file names and not just inside the file.

On windows, an app can install a DLL/lib not part of the application
On Linux, an app can't install something not part of the app but will have a dependancy on it.
the setup manager is part of the os, not provided by the app and will automatically try to install dependancies.
it will also forbid to desinstall a lib used by an application.
I think it's much more powerfull even if this require to not have everything packaged in the app installer.

You can install locally a linux dvdrom (or repository copy)
that would make your install working without having Internet.

BTW, on Windows, I remenber having Office and Windows asking for network installation disk. If you didn't copy the installation disk locally, you've got the same kind of problem. (this is why most people select install everything to avoid being popuped while typing something into word because the software suddenly tries to install a language pack which you don't use...)

You obtain a lesser memory print on Linux by sharing libraries, which is more difficult on Windows, especially for non microsoft software.

humm, both IE8 and Firefox 3.1 will include a private browsing feature but neither have "shipped".
But you're right that IE included it before in a beta and that increased the priority on the firefox people...
Time will say which of these version ship the first (in a non beta, non rc mode)

I find it funny that openoffice is in the situation mozilla was some years ago...
- big code which takes time to clean up (There was some presentation made by an openoffice guy which explained all the work they have been doing to remove old code, factorize code, clean up...)
- mostly contributors from one company, slow to gain external contributors
- hard for external contributors as some stuff are naturally "inside"
- patches sitting and not being integrated
- need to release stuff and at the same time work on more architectural stuff
- work needed on tools to ease distributed contribution and extension stuff

the only difference is that as a product 3.0 is much more a success than early mozilla version so that should help drive developpers overcome the other problems...

I think some of the above problems seems to have been partly adressed but as the number of sun developpers decrease, it complicate integration of needed new developpers...


+ - Stratum 1 ntp server myth

Submitted by ls671
ls671 (1122017) writes "There is a myth that prevails in the ntp community; it is better to connect to low stratum (e.g. stratum 1) servers in order to get more precise time. This is false quite often. It is explained here along with examples of poorly configured ntp servers."

+ - Unpatched QuickTime-to-Firefox flaw dings IE too->

Submitted by SlashNot
SlashNot (666) writes "Security researcher Aviv Raff has found a way to use the one-year-old (and still unpatched) QuickTime vulnerability to automate XAS (cross application scripting) attacks against users of Microsoft's Internet Explorer. To demonstrate the attack scenario, Raff embedded a rigged QuickTime file on Google's BlogSpot to force a Skype shutdown if an IE user is tricked into visiting that Web page. Any limited Web environment that allows embedded QuickTime files can be used to host an attack against IE, Raff said."

+ - IP Traffic Study: Unique visitors vs unique IPs->

Submitted by
Max Fomitchev
Max Fomitchev writes "Hello everyone, A while back I have formulated a hypothesis and conducted a small-scale study showing that the ratio of unique visitors to unique IPs could be as low as 1:10: df In other words judging by IPs there appears to be a lot more unique visitors than there is. The study confirms my hypothesis. Academic skeptics, however, argue that my data was not general enough, so I must conduct another study. Therefore I call for participation among Slahdot folks. I think this is an interesting topic for everyonw to get to the bottom of. If you have a website, which has a login page and would not mind participating — I would VERY MUCH like to hear from you. What I need to collect is a log of IPs and user IDs, which after analysis would reveal how many distinct IPs correspond to a single user in a given period of time. Alternatively, if you have a web traffic logs that you would not mind sharing for analysis (with strict keeping of user privacy) I would VERY MUCH like to hear from you. This study is rather important and I count on your cooperation. Max Fomitchev Assistant Professor of Computer Science & Engineering Pennsylvania State University"

+ - Replacing atime With relatime in the Kernel->

Submitted by
eldavojohn writes "Our friend Jeremy at the Kernal Trap has has dug up some interesting criticism of atime from god himself, Linus Torvalds. As Linus submitted patches to improve relatime he noted: "I cannot over-emphasize how much of a deal it is in practice. Atime updates are by far the biggest IO performance deficiency that Linux has today. Getting rid of atime updates would give us more everyday Linux performance than all the pagecache speedups of the past 10 years, _combined_." And later severely beat atime about the head with a pointed stick: "It's also perhaps the most stupid Unix design idea of all times. Unix is really nice and well done, but think about this a bit: 'For every file that is read from the disk, lets do a ... write to the disk! And, for every file that is already cached and which we read from the cache ... do a write to the disk!" Well, I guess I can expect my Linux machine to become a little bit faster!"

+ - Removable drive Filesystem for Linux and Windows

Submitted by kishore.avv
kishore.avv (923454) writes "Wonder which filesystem /.'ers use for their removable drives (with large numbers of small files), for windows and linux. NTFS is unstable on linux and YAReG/etc. are unstable for large number of files. Is there any really good journaling file system providing driver level (even user level is tolerable) but stable, operation for both operating systems? Googling does not help very much here."
