tiger balm

Published May 6, 2005 by lievenlb

I still
havent received my Tiger-package but got a bit panicky because it is
released as a DVD and at least one of our recent iMacs (the older ones
do not even have build in firewire, let alone enough RAM) cannot read
DVDs. That’s not a major problem as one can always send the DVD back and
ask for CDs instead (and wait even longer) or you can follow this trick (using
Firewire target disk mode). Jan suggested another
approach : make the DVD into a _dmg image_, connect an iPod,
erase with DiskUtility its hard disk and use the _Restore_ option
of DiskUtility to copy the dmg onto it. Then choose the iPod as StartUp
Disk and restart and everything works nicely.

As he went through the
trouble of setting up his iPod, I merely borrowed it and did an
Archive/Install of Tiger on the redundant iMac.All went well and
afterwards you can hardly see the difference with Panther except in the
top right corner where there is the _SpotLight_ icon (a feature I
do like and will use often) and in the lower left corner the
_Dashboard_ icon (a feature which still has to convince me).

Anyway, I wanted to check out as quickly as possible a comment (also
from jan)
that there is a new _Tiger only_ version of TexShop out
which syncs nicely between the PDF-file and the source. As it requires
some extra packages using i-Installer I took the opportunity
to update my TeX-system.

As they predict bad weather for the
rest of the weekend I thought “well, why not just begin the
Panther/Tiger switch on my _iBook_ using the iPod trick as well”.
But first I wanted to backup the latest Tiger+TeX version using
_Carbon Copy Cloner_. Over the last year this has become such a
routine operation (backing up to a slick _Porsche_ designed 250Gb
HD) that I was quite surprised that the computer halted after typing in
the super-user password. Forcing CCC to quit and restarting didn’t solve
the problem so it was time to do a Google on “Carbon Copy Cloner Tiger”
to find out that other (quicker) people had already experienced the
same.

As making a bootable backup is crucial for me I had to
find a way round this and fortunately found the Tiger balm
post. Here’s the hack :

– go to the Applications folder
–
open Terminal and type sudo open
– drag CCC to
the Terminal-window
– type return and provide superuser
password
– open CCC and fill in Source and Target disks as
usual
– it works!

Rumours are that
Mike Bombich will rewrite CCC shortly to fix this problem. Let’s just
hope that I don’t find too many other applications behaving unexpectedly
(in the 2 hours I’m onto Tiger I also found _Remote Desktop_ not
to work at all but then it’s an old 1.2 version so maybe Apple took this
chance to force people to upgrade (and pay heavily) as they seem to do
with hardware (someone should come up with a way to get the first
generation iMacs onto Tiger!)

nostalgia

Published May 4, 2005 by lievenlb

Unlike the
cooler people out there, I haven’t received my
_pre-ordered_ copy (via AppleStore) of Tiger yet. Partly my own fault
because I couldn’t resist the temptation to bundle up with a
personalized iPod Photo!
The good news is that it buys me more time to follow the
housecleaning tips. First, my idea was to make a CarbonCopyClooner–
image of my iBook and put it on the _iMac_ upstairs which I
rarely use these days, do a clean
Tiger install on the iBook and gradually copy over the essential
programs and files I need (and only those!). But reading the
macdev-article, I think it is better to keep my iBook running Panther
and experiment with Tiger on the redundant iMac. (Btw. unless you want
to have a copy of my Mac-installation there will be hardly a point
checking this blog the next couple of weeks as I intend to write down
all details of the Panther/Tiger switch here.)

Last week-end I
started a _Paper-rescue_ operation, that is, to find among the
multiple copies of books/papers/courses, the ones that contain all the
required material to re-TeX them and unfortunately my _archive_
is in a bad state. There is hardly a source-file left of a paper prior
to 1999 when I started putting all my papers on the arXiv.

On the other hand, I do
have saved most of my undergraduate courses. Most of them were still
using postscript-crap like _epsfig_ etc. so I had to convert all
the graphics to PDFs (merely using Preview ) and
modify the epsfig-command to _includegraphics_. So far, I
converted all my undergraduate _differential geometry_ courses
from 1998 to this year and made them available in a uniform
screen-friendly viewing format at TheLibrary/undergraduate.

There are two
ways to read the changes in these courses over the years. (1) as a shift
from _differential_ geometry to more _algebraic_ geometry
and (2) as a shift towards realism wrt.the level of our undegraduate
students. In 1998 I was still thinking
that I could teach them an easy way into Connes non-commutative standard
model but didn’t go further than the Lie group sections (maybe one day
I’ll rewrite this course as a graduate course when I ever get
reinterested in the Connes’ approach). In 1999 I had the illusion that
it might be a good idea to introduce manifolds-by-examples coming from
operads! In 2000 I gave in to the fact
that most of the students which had to follow this course were applied
mathematicians so perhaps it was a good idea to introduce them to
dynamical systems (quod non!). The 2001 course is probably the
most realistic one while still doing standard differential geometry. In
2002 I used the conifold
singularity and conifold transitions (deformations and blow-ups) as
motivation but it was clear that the students did have difficulties with
the blow-up part as they didn’t have enough experience in
_algebraic_ geometry. So the last two years I’m giving an
introduction to algebraic geometry culminating in blow-ups and some
non-commutative geometry.

mind on tracks

Published May 2, 2005 by lievenlb

I just
started putting my mind on tracks but it will take
me a couple of days to offload most of the crap that keeps me awake at
night. There are three main components to Tracks: Next actions, Contexts
and Projects.

“Contexts are very flexible, and can
be places, states of mind or modes of working in which actions can be
taken. Next actions can be assigned to and sorted by context so that you
know when you are able to make progress with items. e.g. “Library”,
“Shops” or “Tired”.” So far I added only 10 contexts : _@inbox_,
_@books_, _@email_, _@home_, _@neverending_,
_@courses_, _@other_, _@papers_, _@computer_
and _@personal_. Probably I’ll have to add others such as
_@refereeing_ etc.

“Projects : any goal
which requires more than one next action to take it to completion is a
Project. In Tracks, you can view your next actions by Project.” So far I
added the first few things that came to mind ranging from small-easy
things such as _Learn
VoodooPad_ over _Paper with Jan_ to neverending-things
like Write nag@n !

“Next
actions : These are the heart of GTD. They are the very next
physical action that can be taken on something. It’s best to phrase
these in an active way e.g. “Call Bob about the committee meeting” or
“Search for a reputable garage”.” Up to now I merely added the next
foreseeable action in each project together with a few urgent persoanl
matters. It is a good idea to give each of these a deadline so they
appear on the screen with a color-code giving the date and red (urgent),
orange (coming up) to green (some day). I realize I’ve been rather
relaxed about my projects so far!
