Eurovision Song Contest 2006

Filed under: Music

Då var det alltså över. ESC2006 är avgjord, och vinnarna är… landet med jumbostatus i dessa sammanhang, som dock nu vann med den högsta poäng någonsin i tävlingens historia… Finland.
Tycka vad man vill, men detta är bara för galet. Jag hade faktiskt hoppats på Belgien. Vad kan man nu förvänta sig om nästa års startfält… ja, det återstär att se.

Ryktet har spridit sig, till och med Dvorak har skrivit om detta på sin blogg:

Och så dagens Douglas Adams filosofi:
Retribution: I’m going to kill you because you killed my brother.
Anticipation: I’m going to kill you because I killed your brother.
Diplomacy: I’m going to kill my brother and then kill you on the pretext that your brother did it.

MFOS och SnabbSkriv

En uppdatering om den lilla boken “Mängder, funktioner och sånt”:
Kapitlet om mängder är i princip färdigt.
Kapitlet om funktioner börjar se någolunda organiserat ut. Men här finns mycket kvar att göra. Behöver även en del figurer för att bättre kunna illustrera koncepten.

SnabbSkriv
———–
SnabbSkriv är ett datorprogram med syftet att effektivisera arbetet. Programmet åstadkommer detta genom att erbjud användaren alternativa metoder för att nå dagliga aktiviteter, detta framförallt genom att göra tangentbordet mer effektivt.
SnabbSkriv är nu snart ute i version 4, och har just nu fåt namnet SnabbSkriv (SS).
Programmet bygger nästan helt på AutoHotkey.
Några funktioner:
Dubbelklick med höger musknapp - Minimerar aktuellt fönster till SS-menyn (BETA!)
Win+F12 - läser upp markerad text (MS Sam, SAPI)
Win+F11 - avbryter uppläsning
Win+i - öppnar Google i standardwebbläsaren
Ctrl+k resp. Ctrl+d - Krypteras resp. Dekryptera markerad text
Win+w - Slå upp markerat ord på Wikipedia
F12 - Kopiera färgvärdet under muspekaren till klippbordet

ENGLISH
=======
SnabbSkriv is a computer programe with the aim of making you work more effectively, by allowing macros and other easy-access alternatives for many regular tasks. Unfortunately as of now, it is heavily dependant on language (i.e. it can not be used effectively in an English environment).
As of now I have no plans of translating this software, but who knows… someday…

Exams

Filed under: Misc, ENGLISH

A quote from Marc Olschok at the Department of Mathematics, SUNY at Buffalo:
(I think this applies to many other subjects as well)

(1) _what_ is tested and _when_ is it tested ?
(2) what _types_ of tests are used ?

(1) One thing, administrators and designers of undergraduate programs
do not seem to grasp is that understanding needs some time to ripen.
Short term testing will put those in advantage, who concentrate on
their test-taking skills instead of deeper understanding.
I am sure that on an exam given 2 month after the course you would
do far better than someone who had only given attention to the
short term tests during the course.
A comprehensive (1yr) oral exam about a _subject_ can tell much more
about the mathematical ability of a student than a lot of tests
during a particular _course_ .

(2) Ultimately, a particular test will only test the skills needed to
take this particular test. A test will be useless unless these
‘test-taking skills’ are related to those skills that are supposed
to be tested.
It might be helpful to look at three popular ways of testing:
homework (with presentation), oral exam, written exam.

With weekly assigned homework problems, the students have to think
about problems for a while, they need to try and retry solutions and
finally they need to write it up. If they have to present their solution
they need to communicate as well (this also regulates excess copying).
The setup can be modified easily to include small groups, working on
problems. Indeed a few carefully chosen problems (about 4 or 5) are
enough.
At the same time, students learn to utilize resources like libraries
and fellow students.
Tenancy, patience, care and the ability to write and speak Mathematics
is tested and developed at the same time with this method.
These abilities are indeed necessary for doing Mathematics.

In an oral exam, the students can adjust to the level of the
examiner (no joke intended) as far as precision is concerned.
The students need an understanding, deep enough to actively explain
material. At the same time they have the chance of showing what they know
instead of revealing what they do not know.
Sufficient understanding of the material and the use of mathematical
language are necessary for such an exam; skills, they need later
on within Mathematics and other fields.

For a written exam, the students have to train rather than learn.
They are put under restrictions of time and resources, both of which
usually do not occur in mathematical work.
The question is not whether they can explain Mathematics or solve problems,
but whether they are able to solve problems under these restrictions.
In this setup, deep understanding has almost no effect: there is neither
space nor time for questions, concerning understanding.
In fact, a more conceptual approach to a problem, that might give a better
solution afterwards, will often need more time than provided, so that
in this setting understanding might get in the way.
The strategy
- look at plenty of test problems before the test and memorise solutions
- recognize a problem during the test
- dump the precompiled solution on the paper
will lead to ‘better’ results, than learning and understanding.
I do not claim that the skills, needed for written exams are completely
useless. They are very important for … written exams.
However, they do not have much relation to Mathematics.

Currently, the emphasis is on short term tests in the form of written exams.
Perhaps this is due to the image of ‘objectivity’ they enjoy.
At the same time, grades determined by these exams are valued high
by administrators.
Only a few students have courage enough to withstand this pressure and hold
on to learning in this environment.
For the majority, the result is graduation in test taking, rather
than Mathematics.

Victor Borge quotations!

Filed under: Humour, ENGLISH

Here are some of the funniest quotes by Victor Borge, gathered from various places around the ‘net.

Sometimes I play requests, if someone asks me to.

The difference between a violin and a viola is that a viola burns longer.

Laughter is the closest distance between two people.

I only know two pieces; one is ‘Clair de Lune’ and the other one isn’t.

He was happily married - but his wife wasn’t

You want something by Bach? Which one, Johann Sebastian or Jacques Offen?

Mr. Azruni’s uncle lives in Istanbul and is a road engineer. He was run over by a steam roller about five months ago and is still in the hospital in Room 21 to 27.

(Talking of his two children) Mine are twins though. Both of them. (Comedy in Music)

Pete (Peter Ilyich Tchaikovsky) was born in Votkinsk, May 7 1840. When he was a little boy he never played out in the streets of Votkinsk like the other little children of Votkinsk because when Tchaikovsky was one month old his parents moved to St. Petersburg. (Comedy in Music)

This is a piano concerto for piano and concerto and was originally written for approximately 95 pieces symphony orchestra. Due to circumstances beyond my control we seem to be approximately 95 pieces short. But you won’t notice the difference because I play it very fast. (Comedy in Music)

Var är jag?

I övrigt kan man hitta mig som Cab på t.ex. AutoHotkey-forumet. Cab bara för att det har tre bokstäver, är lätt att skriva, och för att folk ska ha något att fundera på.
