Welcome to my link farm. Nothing fancy. Just a few links.
Aviation stuff:
This page seems to have a lot of information about
Bernd Ewald's project to
build a full scale Horten IV but, alas, most of it is in one of
the many languages I can't read. An English translation of
one of Mr. Ewald's articles was published in the winter
2001/2002 issue of the Vintage
Glider Club News.
In the mid '90s Ulrich Schäfer built a motor glider called " Aachen" . Mr. Schäfer has expressed interest in building another flying wing . Hopefully he will be able to continue with this project in the not too distant future.
The German word Nurflügel means "only wing" and that's exactly what you'll find on the Nurflügel page, historical information about, and pictures of all-wing and tailless aircraft. You can read some more history of the Horten's in this Flight Journal article and in this "Aérostories" article. After WW II Reimar Horten found himself an aeronautical engineer in a country without an aircraft industry. To find work he, like many Germans in similar circumstances, immigrated to Argentina . Here is an article about the Smithsonian's collection of Horten 'wings and the H 229 center section in their collection.
TWITT (The Wing Is The Thing) is the largest collection of current flying wing info on the web. Physically located in southern California, they meet every other month and publish a newsletter with the goal of helping flying wing enthusiasts around the world share their project results and offer encouragement to one another.
An acronym that has become popular in the last 30 or so years is BWB. McDonnell Douglas was working on one such design before they merged with Boeing. Befor the merger NASA was working on a 4,000 bl dynamically scaled model of the BWB called the X-48a but that was canceled for budgetary reasons later it re-emerged as the much smaller X-48b.
If you're interested in models Andy MacDonald's Flying Wing Page is a good place to find inspiration. Carlo Godel's page was a wonderful source of plans for vintage models. Carlo is gone now but his web page can still be retrieved from the Wayback machine.
If you are interested in designing your own flying wing this page from Applied Aerodynamics: A Digital Textbook provides some useful guidance. You will also find some analysis software and lots of great modeling information on Martin Hepperle's page.
Bill and Bunny Kuhlman (aka B2)
publish specialty books for aeromodelers. Of particular
interest to tailless designers are the Panknin
Twist Formula for calculating linear twist for a swept
flying wing and Irv
Culver's formula for non-linear twist. These
formulae are in Appleworks and Excel format and can be converted
to run in most spreadsheets by using the <Import> command on
your software's <file> menu. In addition to the web
site they write a column for Radio
Controlled Soaring Digest called "On
The 'Wing" and many of those articles also eventually
become available as PDF files.
This page by Matthieu
Scherrer shows a relatively simple formula for generating a
non-linear twist distribution of the Horten style and a model he
used it on. There is another, somewhat more elaborate (read
"intimidating"), formula for calculating sinn
twist. However, I've been told that this is only a
mathematical approximation of the method Dr. Horten used to get a
bell shaped lift distribution and doesn't quite produce the same
result but it's real close. To see the result of this
formula have a look at Mike
Allen's page .
I've been working on an introductory page on Vortex lift , it's not finished yet but you're welcome to look at it (spelling and grammatical errors included)
Here are some links to multi-element airfoils
Operating system stuff:
The Linux documentation
project
Dell is selling notebooks
that are supposed to be tough enough for teenagers, Woohoo!!!
The Linux Gazette.
"One can not unite a community without a newspaper or
journal of some kind"
The
Linux portal It used to be called “Linux links by Goob”
I liked the old name.
If you are looking for a Linux users group in your area, or want to start a user group, GLUE, Groups of Linux Users Everywhere, can help.
Much of the operating system that is distributed with the Linux kernel is composed of software that comes from the GNU project and the Free Software Foundation.

Miscellaneous:
About a third of the links on
The Good page are aviation related but the rest are fun
and interesting too so I am listing it as miscellaneous.

Let's not take ourselves too seriously:
Did you know that it's illegal, in some states, to carry an ice cream cone in your back pocket on Sunday? It is also illegal to ride a horse in Colorado while under the influence alcohol. Many other quirky ordinances are listed at dumblaws.com . Personally, I would never consider riding a drunk horse :^)
