Here's a nice list of 50 things to avoid when writing called How To Write Good.

Retorik Magasinet

Jeg vil gerne slå et slag for det fremragende blad RetorikMagasinet. Du kan læse Weekendavisens rosende omtale af bladet her.

Calc5

With the online calculator calc5 you can plot 2d and 3d graphs, make symbolic calculations such as derivation, and browse 2d graphs with zooming and panning.

Faulty Arguments

With this quality List Of Fallacious Arguments you'll be prepared to sidestep faulty logic in arguments. Your own as well as others.

How Cellular Phones Work

The article Cellular Telephone Basics taught me how cellular phones actually works. Nice. As a shorter, but not superficial, intro to the subject I also recommend How Cellular Phones Work from the excellent site Howstuffworks.

Onelook

Onelook Dictionary Search is an astonishingly useful ressource. It let's you look up an english word or term in 98 different quality, online dictionaries in one go. It also offers a powerful wildcard search.

Douglas Rushkoff

Douglas Rushkoff is one of a few heroes of mine. He did quite a masterpiece of a speak at the Reboot 4 conference here in Denmark, presenting his thoughts on media social psychology and history of ideas. It's a pleasure to watch. Lots of powerful input.

Onelook Wildcard Search

I would like to bring to your attention that the excellent collection of good quality online dictionaries Onelook has a valuable feature. It allows for searches with wildcards. For 1 letter ?, for at string of letters * e.g. "fore?t" or "fo*st" but finds the word "forest", as well as other matches.

Go Berkeley!

Another sweet source of information here at ddavid.dk - Where Information Comes to Hang Out. Berkeley University of California has been so kind as to put online podcasts of series of lectures. You will find both audio and video, and you will find it here.

Analytical Puzzles

Here's some analytical puzzles to help vaporize the alcohol from last night. Yes. You drank last night.

Mental Calculation

For the matematically inclined, this article from Wikipedia on Mental Calculations has some good info on how to do calculation in your head. The methods I liked the most are Indirect calculation, Using square numbers, 9 and 3 rules, Approximating square roots and Squaring numbers near X.

This article on calculating the day of the week of a given date is really good. It taught me how to calculate the day of the week of a given date.

Social Psychology Basics

I am still in the finishing chapters of Dr. George Boeree's Social Psychology Basics. Good one. Basically it's just a free textbook. If that turns you on, it's cool.

Security Now

I highly recommend GRC's Security Now podcast with Steve Gibson and Leo Laporte to the technically inclined. It's 36 episodes and counting of high quality education on computer security related subjects, with a focus on the basics, brilliantly explained by the very competent Steve Gibson.

A certain basic level of knowledge of computer theory is required.

90'erne - hvordan var de?

Henrik Dahl har Mogens Lykketoft i studiet til en samtale om 90'erne i udsendelsen 90'erne - hvordan var de? Georg Metz er med på telefonen. Udsendelsen er et godt tilbageblik på en tid, det kun lige er blevet muligt at begynde at se tilbage på.

ManyBooks

ManyBooks is a pretty impressive collection of free eBooks. You can download the books in a variety of different formats, including PDF and iPod Notes. I think you will be able to find most classics there. As a measure of the size of the collection, the listing of authors starting with the letter S amounts to 420.

The Lie About the Lie Detector

Oh, the number of times you have been told by people on your television that it is possible to cheat a lie detector and thought "Yeah, well - how?!". No more. I give to you The Lie About the Lie Detector - a 220-page all-you-need-to-know PDF on the subject, created by AntiPolygraph.org.

There is nothing like the feeling of "I'm not supposed to know this".

Efterretningsvirksomhed

Hvis du er interesseret i efterretningsvirksomhed, bliver du nødt til at læse Lars R. Møller: Operation Hurricane - Efterretningsvirksomhed før og nu. Jeg er virkelig imponeret over det arbejde, der ligger i den bog, og den grad af information, jeg føler jeg har modtaget efter at have læst den. Den behandler emnet teoretisk, og kommer samtidig med en masse historiske cases. Læs den!

Logiske kortslutninger

Her kan du læse en ret god gennemgang af en række almindelige logiske kortslutninger. Lær dem, og undgå dem.

Forhørsteknik

I anledning af sæsonpremieren på den fremragende serie 24 timer - 4. sæson i DK, 5. sæson i US - får du lige CIA's gamle forhørsmanual fra 1963 KUBARK Counterintelligence Interrogation, og den kortere opfølger fra 1983 Human Resource Exploitation Training Manual (selve den scannede version af sidstnævnte her). Lisa Haugaard har skrevet en god artikel bl.a. om disse to tekster, ved navn Textbook Repression: US Training Manuals Declassified.

Christian Kock i Dahls Duel

Dahls Duel på P1 handler denne gang om politisk retorik, og har titlen I politik gælder alle kneb. Professor i retorik Christian Kock fortæller bl.a. om tre meget almindelige retoriske tricks, som jeg er glad for at have lært at kende. Citat fra programmets hjemmeside:

"Den politiske debat i dagens Danmark er præget af monolog frem for reel politisk diskussion. Spin og medietække er en nødvendighed, når politikerne skal høres, ses og vælges.

Men har det ikke altid været sådan, og er politik i virkeligheden et spørgsmål om samtale. Og hvorfor skulle politikerne ikke bruge beskidte kneb, når nu vælgerne er ligeglade med, hvad der er sandt, og hvad der er løgn.

Henrik Dahl har professor Christian Kock i studiet til en diskussion om politisk kommunikation og grænsen mellem ædel retorik og kynisk manipulation."

Ecstasy

De fleste af de ting, du har læst om MDMA (Ecstasy), er baseret på uvidenskabelig og direkte forkert forskning. Denne artikel gennemgår de forskningsresultater, du er blevet fremlagt, i Ekstra Bladets forgange kampagne og lignende. Tænk Parkinson's, 'huller i hjernen', dopamin- og serotoninmangler og billeder af 'din hjerne, og din hjerne efter Ecstasy'.
Rick Doblin, Ph. D, fra MAPS (Multidisciplinary Association of Psychedelic Studies), har siden 1986 arbejdet for at genskabe muligheden for MDMA-research, og bringer her et par store myte-busters. Formen er ret videnskabelig, så vær forberedt på at læse langsomt. Til gengæld kan du bagefter fortælle folk, at de tager fejl. Det er herrefedt.

Update:

Sundhedsstyrelsen lavede i 2002 en undersøgelse af indholdet af ecstasypiller. Imponerende initiativ, synes jeg. Citat fra rapportens indledning:

"I sommeren 2000 fokuserede pressen på ecstasy på baggrund af flere dødsfald blandt unge der havde taget ecstasy samt rygter om tilsætning af heroin til ecstasytabletter.
For at styrke den nationale overvågning af ecstasy besluttede Sundhedsstyrelsen og Rigspolitiet at igangsætte et projekt bl.a. med det formål at få viden om hvad ecstasytabletter egentlig indeholder, og hvilke ændringer der sker over tid hvad angår indholdsstoffer og stofkoncentration."
