An innovative company probably needs both: quirky people with unconventional
work habits but who have ideas and can break a lance.
If they are not particularly good at documenting things, it should be
easy to have this done by others who are good at learning, absorbing, cleaning and
improving a good idea.

Ashamed of being
fucked with, victims call "conficker" now "conflicker" or with the euphemism

The source of the claim seems Gutmann's 1996 article:
http://www.usenix.org/publications/library/proceedings/sec96/full_papers/gutmann/index.html
where he says:
"Data overwritten once or twice may be recovered by subtracting what is
expected to be read from a storage location from what is actually read.
Data which is overwritten an arbitrarily large number of times can still
be recovered provided that the new data isn't written to the same location
as the original data (for magnetic media), or that the recovery attempt
is carried out fairly soon after the new data was written (for RAM)."
It was challenged already in 2003
http://www.nber.org/sys-admin/overwritten-data-guttman.html
where Feenberg writes:
"Surveying all the references, I conclude that Gutmann's claim belongs in the category of urban legend."
As usual, this story shows that individual claims have to be checked by
independent parties. Even the claim that it can not be done.
I would have expected that on a military level, all
software and operating systems used should be compiled
from source, the source checked and risky features locked
down. That would exclude proprietary operating systems
like windows and mac OX and even prepackaged open source
systems. Its probably not cheaper but cases like this should
be wake up calls.
A degree in math opens the door to many other areas:
computer science, any other science, teaching or management. It
essentially provides the flexibility and ability to
think abstractly. Doing mathematical research is only
one option, the actual work can be very applied. A good
math education teaches naturally how to understand a
complex issue, reduce it to a model which can be solved. Starting
with "hard science" makes other areas easier to understand.
A good reading for a student pondering the question whether math
is an option is Ian Stewart's book "Letters to a young
Mathematician".
The question is not so much functionality or reliability.
This will eventually converge. The main difference is
confidentiality. Are the data on google docs treated
correctly? Is it possible to access them for other purposes?
It is convenient for example for schools to collect grades
on a google spreadsheet. Are these data kept away from
third eyes? Are students with good scores for example
being targeted suddenly by job hunters? I'm not aware of any
case, where data has leaked, but we put a lot of trust in
companies offering online applications.
There is an art in finding good questions. Hilbert did it in 1900
with his 23 problems or the millenia problems in 2000. Some of the 23 problems
stated are too vague. The first example:
"Develop the mathematics of the brain". This covers large
parts of computer science, artificial intelligence and psychology.
What does "mathematically consistent" mean?
A mathematical problem can be taken seriously if there is a clear
goal and if there is a possibility to determine, when the problem is
solved. This is not the case for many of the problems listed on this
website.
I read first "Indiana Jones Nukes Market"
Must have been the economy news from last week and CNN story
"U.S. seizes two mortgage giants" which popped up just before.
One of the strengths of TeX is that it does not change.
I can TeX with minor adaptations a text I have written
15 years ago and I know that I will be able to process
it in 15 years.
An other strength is its flexibility. Any replacement which
dumbs things down makes things more rigid. LaTeX itself is already
a "dumbed down" version of TeX which sacrifices some of the
beauty of TeX but makes it more accessible. I myself use it primarily.
I could imagine a variant of LaTeX, which makes certain things
easier, like positioning of pictures.
From the user prespective the problem of LaTeX is that it has a relative
steep learning curve which once overcome saves enormous time. Processors like
Word get you started immediately, adding more and more frustration once the
user wants more control.
Modern day educational needs and goals are far different from what
they were in past centuries or even a few decades ago.
This is a triviality. Things always change. Wieman does not give concrete
examples what change he means.
Everyone is aware of the enormous increases in the capabilities of information technology (IT) over the past few decades,
years, and even months. These offer many fairly obvious opportunities for
dramatically changing how teaching is done in colleges and universities,
and in the process, making higher education far more effective and
more efficient.
Again, there are no concrete pointers, how these changes should be done
and what is wrong in higher education. Enormous changes have been done
already: examples are web resources, collaborative group work using wikis,
internet based labs, online testing, personal response systems, computers
in classrooms, demonstrations, blogs, online discussions, polls, lectures
on youtube etc. Some technology based changes have already peaked 10 years
ago. I had to give lectures were given in computer labs because it had
been considered cool that every student has a computer at hand. An other
example from math: Computer algebra systems had been forced into every
lecture without realizing that many teachers were not able to use them.
Please, Mr Wieman be more concrete and provide concrete suggestions what
changes should be done and if, how it will be achieved.
Actually, I will keep this article as a prototype of how not to write
an essay. Want to write an article about parentning? Just take Wieman's
template and change a few words. It sounds good but is as empty as the
article itself. Here we go:
New parenting Model Needed
There are currently great needs and great opportunities for improvement
in human beings. As world population increases, we need to provide more
childen with complex understanding and daily problem solving skills in
all subjects to allow them to be responsible and successful citizens in
modern society. Emerging research indicates that the inhabitants of our
planet are not achieving this. However, there are great opportunities
to improve this situation using advances in the understanding of how
people learn to live and to tackle daily challenges.
The current model of humans grew in a haphazard fashion that has left us
with traditional practices and modes of organization that in some aspects
are poorly matched to modern needs. It seems likely that the world grew
out of the parenting model of an expert working closely with a kid,
assigning them challenging tasks and then providing guidance as needed
to carry out those tasks, as well as offering ongoing feedback on their
work. This model, or its modern day embodiment of "the expert individual
parent," remains the most effective demonstrated approach to life.
I'm glad Mandriva is around. Ubuntu seems to have more
momentum (and I use it a lot too), but what if
Shuttleworth stops his efforts and some follower tries to cash in
or make deals with companies which are less philanthropic, but help
to control a competitor.
We have seen other distributions like RedHat, Suse make
rather drastic changes in the past and not all to the benefit of
the distribution community.
Its good to have choice and I found Mandriva an excellent
distribution too which minimizes the amount of time to spend
with sysadmin work.
The point for "blink of an eye" decisions is made by
Malcom Gladwells book "Blink":
"The Power of Thinking without Thinking". A worthy
rebuttal is Michale LeGaults book "Th!ink",
"why crucial decisions can't be made in the blink of an eye".
I found both worth reading and both have a point. It depends
on the decision to be made.
here is a test, to find out whether you belong to the "discovery" or "invention" camp.
I write down a 100 digit number (with breaks are to pass the slashdot filter):
did I invent this number, or did I discover it? Nobody has written it down already, so I
invented it. However, the number system exists already as a definite point on the number
line which we all think to know, so I discovered it.
They can solve the problem by adding the feature that online documents can be stored
in encrypted form using encryption which also google itself can not crack. Collaborators
exchange keys with a diffie-hellman scheme. The technology is ready. Google just has to
make it available. Now, most people would not bother with this but things like business plans,
coorporate strategies, merger plans or patent drafts would definitely need encryption.
The same with gmail. It should become easy to exchange encrypted email. As usual, the
implementation of these services should be public. This is reasonable because one can do
all the encryption and decryption on the sender and receipient side. This has to be done with
software, for which the source code is visible.
> that it hopes will become a standard. These gestures include: scrolling by making a circular motion
and move the finger up and down to turn the picture? Come on!
