Hi,
long time coming - but I thought I better write something..
A quad core 386 box here has been tracking each ubuntu update since 2009.
With the previous Ubuntu (11.10) the samba4 package generates a warning
on each time
you install a new package or get the latest update.
On upgrading to 12.04, sound went backwards. I could not get the
microphone input to work.
Ok, - complete fresh install - maybe there is some software
configuration something hanging around
from an old install..
======
The install went without problems. Nothing of note to report here.
The comparison of speeds etc is all of the Ubuntu 12.04 versus the
fresh install of Ubuntu 12.04.
synaptic runs much faster now. it would take 5 seconds to find all
packages etc that match the supplied search phrase.
Now it is under a second.
The creation of a terminal (with Ctrl-t) is much faster now. Instead of
over a second, it is definately under a second.
Sound works for mic and speaker nicely now. Plug the 3.5 mm jack for the
mic into the front socket on the computer and
the sound dialog lists the front socket as a possible input (but does
not mention the mic socket at the rear of the computer).
Move the 3.5mm jack for the mic to the rear socket of the computer - the
sound dialog lists the rear socket as a
possible input (but does not mention the mic socket at the front of the
computer).
A frustration of linux sound of 3 years ago was when using multiple
sound cards. [Multiple sound cards are common -
consider a laptop with a usb headset - this counts as multiple sound
cards]. Playing you tube videos would display the
video nicely, but no sound. Typically, the browser (or flash plugin) was
sending the audio to the wrong sound card.
The current ubuntu does this a lot better - I think the credit goes to
the presence of pulse. After some thought, I cannot
remember when youtube videos played badly.
I have a 120K lines of a C++ program here. This program compiled in 3
mins 15 sec with the upgraded 12.04.
2 mins 45 on the fresh install of Ubuntu 12.04
Ubuntu 12.04 brings some designer tweaks - it is not possible to set the
number of virtual workspaces from the system menus - instead one has to
dynamically add more as you require. There is a package called
ubuntu-tweak that lets you
configure the default number of workspaces.
--I have not found the configuration option so that windows are
automatically selected when the mouse moves over them.
Automatic selection of a window when the mouse moves over it is a pain
with the Unity interface.
I installed indicator-multiload to display on the panel at the top the
cpu/memory/load etc graphs. There was a indicator-workspaces tool for
Ubuntus older than 12.04 (which shows on the top panel what workspace
you are on). This indicator-workspaces apparently works on 12.04, but it
would not install for me - sigh..
The speed differences between the upgraded ubuntu 12.04 and fresh
installed 12.04 are probably due to the reduction in
the number of files and old (outdated) configuration entries - but it is
certainly enough for me to recommend a fresh
install as the ideal.
Code completion:
it has been a source of much angst that linux IDE's for C++ are not
that good. In my view - code completion should
always work. This saves much time - I don't have to remember if it is
GetMilliseconds(), or GetMilliSeconds(). The version of codelite in
Ubuntu 12.04 did correctly handle all the code completion tasks I tested
it on. My test case requires it
can code completion code from the libraries PTLib and OPAL. (these
libraries are used by Ekiga). To give you an idea,
ptlib and opal and have been written by somebody who has considered the
entire C++ language space and endeavoured
to use every possible feature. (Ok, not true, but it looks like
ptlib+opal were written on that basis).
Yes, you can suggest emacs and vim for an IDE. I would not suggest this
approach.
Summary:
a fresh install of 12.04 was worth the hassle. I like it.
That should be enough to elicit 1 or more responses
Cheers,
Derek.
