No, the problem come from the device driver for scanner devices which are raw scsi devices and therefore have some very restrictive security set.
The hot plug manager should change the user id to the logged in user - but that is not reliable. Personal experience in 50% of cased it stays on root so only root can scan.
And even if the user is changed - have 2nd user logged in and only one can scan.
Only when the little bugger of an hotplug-manager changes the user id for the scanner device to the logged on user. Which still only gives one user access to the scanner. Have my Wife remote logged in and only one of us can use the scanner.
Unix security if just flawed and the flaw is called "root".
Year that's the theory - in praxis I quite often have to start xsane as root because - for whatever reason - the scanner device security is set to:
brw-rw---- root disk
Unix security is just not up to today's desktop hardware with scanners, usb stick and whatever else. The inflexible root-centred security system is no good for hot-plugin.
I like this little trivia: http://en.wikipedia.org/wiki/Unix#1970s - Multics - multi-user-os - unics - uni-user-os. And it is still that way - root is the only true user the rest are just cripple.
I expect that you install the drivers as root. The installation routine then sets suid to all applications which use a scanner.
And somehow I understand it - quite often I had to start xsane as root because the current user just was not able to access the scanner device - and I wanted that bloody scan now and not in half an hour problem searching session.
Sorry my English (I am german). What I wanted to say was "hat seit" which (in German) means that a specific attribute has been attained somewhere in the past and continues to the present.
Indeed!
Abuse any system and it WILL break, eventually.
Remember my other post? The interesting one was the priority inversion on my Linux backup. An online backup should not abuse the system.
A Real-Time OS might be helpfull here as it protect against that ans other problems. And a real time programming language like Ada. But that is a mute point as Ada's Real-Time-Annex will only (fully) work on a Real-Time-OS:-(. BeOS was particularly sensitive to memory shortfalls, for example. It didn't take much paging activity to make it grind to a halt, even right up to the end.
That is strange. I never noticed when using BeOS but then I had memory without end at the time. But what I did notice was that BeOS needed a page file at least the size of physical memory - and I thougt that was so for speed optimization.
I got an 2000 at work and XP at home. The 2000 is worse - but that's probably because system department choose such a great virus checker. Still - in a proper MT system the virus checker should not bring the system to a standstill (only the one thread waiting for data to be checked should be affected).
* Click with the Mouse - nothing happens. * Move the Mouse - nothing happens. * Type on the Keyboard - nothing happens. * Type Ctrl-Alt-Del - nothing happens. * Type Shift-Ctrl-Esc - Task manager does not appear.
Especially the last one is bad as the task manager should enable you to kill evil jobs.
Ah, at work especially the (on access) virus checker grinds the system to a hold.
BTW: It it the same for Linux - with one difference - here it is the xfsdump backup utility which grinds the system to a hold. Probably a Priority Inversion [1].
So, NO: neither Windows nor Linux have really good multi tasking.

The reality, however, is that these new languages which provide the newer and better paradigms for thinking and reasoning about concurrent code, just aren't going to get developer uptake. Programmers are too conservative and too wedded to their C, C++, and Java to step off and think as differently as the solution really requires. Programming languages with build in multitasking are not new. We have have them for quite a while now (see http://en.wikibooks.org/wiki/Ada_Programming/Taski ng - Ada was designed in the early 80'th). They where just ignored by PC programmers because there so heavy weight and difficult to learn. Both not realy true. And as you said: Quite a few programmers don't want to learn anything new:-( .
Who cares? Do they work? No, they are missing important features.

for secure programming. But that not unusual. In fact that seems to be the Zeitgeist.
Everybody speaks of secure programming but allays in combinations with unsuitable tools and programming languages.
Reminds me a bit about the Addams Family. Remember the part where Gomez tries to make huge loss of money. In the end he start a venture in Chocolate-Diet - something he things will never work as chocolate is completely unsuitable for diet purpose and his hope is that people won't fall for such a stupid idea - hence he is going to loose money on the venture.
Of course we now how it ended: Chocolate-Diet was a huge success! He made tons of extra cash. Because people love to go the easy way - even when it is blatantly clear that it won't work.
And the same here: Instead of going to the pains of learning a programming language and/or tools suitable for secure programming you just go or be send my management to take a silly test [1]. Only difference: Unlike Gomez Addams the "Software Security Institute" knows very well how people (and especially managers with little technical knowledge) work and that there "Chocolate-Diet" will bring in the cash.
Of course no./ article of mine on secure programming without me mention that Ada [2] is well suited for secure programming and since PHP was mentioned: How about using the Ada Web Server [3] for truly secure your web applications? Yes, it will take longer to program for the AWS then quickly hacking together a PHP application. But the bitter truth is: quick hacking and secure programming are mutually exclusive.
which is a more tricky - but still not impossible. Just de branded my P990i - took me half an hour and cost 6,--.
The point is that branding is done on the firmware level - that is: the carrier supplies a specially modified operating system for your phone. With that they can switch on and off almost any feature they like.
But this also means that every operating system update need to be re branded by the carrier. I suggest you have a look here: http://uiq3.sourceforge.net/wiki/index.php/CDA/P99 0i. Of course SEUS (Sony Ericsson Update Service) will check you Phone (by that magic CDA number) and only offer updates which have been authorised by by your carrier.
Most branded P990i are now two or more versions behind the current release. For Joe Average this might be Ok - But Bill Poweruser might not like that. Note that nowadays even for (smart)phones version 1 of the operating system almost unusable. See http://my-symbian.com/forum/viewtopic.php?t=28242.
Interesting point. However, there are several resons why not:
1) Page-Name typos - why keep them online? 2) SPAM 3) Illegal content 4) Unwanded content - Each wikipedia project has a mission and will not accept content which is utside scope.
If you disagree in a particular case you can file a "vote for undelete" and ask the adminstrators to make the content available.
