I believe Luca suggested to unmount a filesystem automatically,
therefore there would be no need to have any term in the user
interface.

It helps newbies who/if are curious. When a newbie learns it then it
becomes "the frobnization needed to unplug my media" anyway. For
others it FORCES them to understand an implementation detail which
they are not interested in and which works no matter if they know it
or not. People use their media to solve their needs (watch a movie,
copy a homework assignment, do a backup etc), not to learn what random
obstacles (their point of view) they have to overcome to get their job
done.

It helps 1% of population once and annoys the rest for a lifetime.

(I do care about teaching a new generation of programmers and power
users but I do not want to ditch regular users in the process. I want
to fix existing deficiencies, not to teach users how to workaround
them.)

In general the mental model of an author is different from target
audience's model. (In 1970's the authors and users were the same
people.)

Ubuntu strifes to be good for all users. If we do not know how to
achieve that then we aim for majority. Advanced users can tweak the
settings anyway, and they seem to like it - even when there is no
point of doing so. (Also they might want to uninstall X - many rants
seem to be related to a GUI application now allowing to do something
which used to be possible on command line only.)

(Actually 'mount' is of an UNIX origin but that's not the point.)

A real geek does not use automounting. (Shame on you!) He does know
the name of the kernel module for FAT32/NTFS/whatewer and knows the
plugged device's name in /dev/*. He will do this every time he plugs
in a device because it is good for exercise/practice and because he
has full control of the operation.
It will teach you how hard it is to do things manually, specially if a
person does not know the tiny technical details. It is a great
opportunity to learn how to write a script which custom-mounts the
disk when triggered by HAL or whatever system we are using now.

(An possible fix is to mark the filesystem as "mounted by a suspended
system instance XYZ - do not mount RW unless you are the instance
XYZ". VoilĂ , your need is satisfied. Also users can now multiboot
safely when their other system is hibernated.)

[Bug 567913] Re: No audio in wmv-files: Cannot find codec for audio format 0x161

2010-04-27 Thread PetrB
Marc Deslauriers: It is better to have a secure system than a compromised 
system with WMV+sound. In general reverting a security fix because of 
functionality regression is insane.
I trust you had some reason, for example:
- the original CVE-2009-46XX/security-issue22.patch in fact did not fix 
security bug (or any bug) or
- the security bug is unlikely to be exploitable or
- the bug is not exploitable if patches 01 to 21 remain applied or
- the code is exploitable but it runs in sandbox therefore no real harm is done

I suggest putting a rationale in an update next time.

For those interested the patch is

In general "mount" is related to copulation. On Unixes it is something
with filesystems but people live in real world more than they do in
Unix world.
The desire to avoid the word "mount" is rational - it is explained in
bug description, comment #23, #26, #41, #67. Yes, users are irrational
but there is nothing we can do about it.

"Power down" - and some user will come and scream that just powering
down is dangerous and he also wants to to unmount the filesystem. In
fact he does not. He typically wants to remove the hardware and
instructs OS to do whatever is needed for that - including perhaps
unmounting, feeding the gnomes, checks if right falange is good or
whatever. Implementation details.

[Bug 28835] Re: "Unmount" in volume right-click menu, is tech-speak and undiscoverable

2009-06-25 Thread PetrB
Psy[H[]: "mount" is established between UNIX/Linux programmers, administrators 
etc. These people make 1% of population. Therefore "mount" is *not* established 
word in general population.
The specific action of "unmount" is to remove something from something. People 
do not know what filesystem or partition is - this is our business, not users' 
(it is an implementation detail for them).

Instead of "Please unmount storage before..." use "Please right-click on
the drive icon and select 'unmount'...". The original sentence tells
them they need to unmount but they still do not know how to do that. The
second sentence tells 'how' (not 'what' - users do not care anyway) but
user will only remember to select 'the weird word' in the menu.

In general, users can not be educated. And we can design things in way that 
this is not a problem.
Consider writing replies to me (petr@gmail.com), others likely already know 
the philosophy.

LKRaider: That would be probably the best option. Unfortunately it looks
difficult to implement.

Pressing Fn+F6 does not produce anything in /var/log/acpid and xev does not say 
anything either but linux kernel produces this in dmesg:

Now I can use "cheese" to see  myself. After pressing Fn+F6 second time

I used to have the same problem (the 0c45:62c0 Microdia did not appear
after the Fn+F6 keypress) but it started working although I have don
nothing to fix it.

There has been rumor that hibernation on WUBI installs (which uses swap

Disabling hibernation if swap is on file - is it too aggressive
approach? I mean, the crashes are reported to happen on Wubi only (where
are the reports anyway?).

Some people use swap file only and there even was a discussion about
using swap file as default in some distro since it make installation
easier to newbies and has negligible speed impact
(http://www.ussg.iu.edu/hypermail/linux/kernel/0507.0/1690.html).
