Hueniverse: Elements of API Security
This does not explain whether it is possible to encrypt the session token cookies while avoiding HTTPS for the non-critical data in the session (such as the HTML.)
-
To prevent replay attacks (someone grabs the API request and use it unchanged to make API requests), the client adds a nonce to the API request before signing it. The server will only honor each nonce one time from the client, so if captured by someone else, the server will refuse the call.

Yahoo! Small Business - What is RTML?
The DSL developed by ViaWeb
-
# RTML has a structure editor for editing templates. Instead of typing in your whole program, you choose code units from a menu, then fill in the blanks. This approach eliminates the syntax errors that are usually such an obstacle to novice programmers. It is impossible to create an ill-formed RTML template.
# RTML yields HTML as its output, so anything you can express in RTML can be viewed on an ordinary browser.
Lisp in Web-Based Applications - Paul Graham 2001

One way we used macros was to generate Html. There is a very natural fit between macros and Html, because Html is a prefix notation like Lisp, and Html is recursive like Lisp....In fact it turned out that Web consultants didn't like Viaweb.
Consultants, as a general rule, like to use products that are too
hard for their clients to use, because it guarantees them ongoing
employment....But by using closures, we could make it
look to the user, and to ourselves, as if we were just doing a
subroutine call.
ArsDigita Server Architecture
Interesting package of engineering and management advice

What if a disk drive fills up? Are we notified in advance? Are we notified when it happens? How long does it take to restore service?
That's what's this document is about.
Using the ArsDigita Community System
Community and ecommerce combined. This explains why Greenspun is "semi-retired" after he was bought out of ArsDigita.
-
Installation of the ACS consisted of feeding the data model to Oracle and putting the HTML and Tcl documents in the correct locations. Adding our products to the catalog was done with a browser-driven import routine. We have over 30,000 products in the database with no speed or scalability problems so far. The ACS ecommerce module was easy to integrate into our existing site ... It takes us at least half a day to set up an ACS (download .tar file, set up new AOLserver or Apache, create new Oracle user and tablespace, edit the parameters file to give the service a name, etc.)...(If you're thinking that this is the complete set of features that eBay has, you're right. We built it before they did but we forgot to raise money and hype it; so they are multi-billionaires and we remain ... computer programmers.)...We are some of the highest paid programmers in the world, with 100% ownership of a ArsDigita.com, a 60-developer profitable company with $20 million in annual sales (February 2000; sales should double every six months).

What I'm getting at is that OACS is so far ahead of any other framework out there that it's funny!
Sites That Don't Work (And How to Fix Them) - Philip Greenspun
Phil Greenspun had solved most of the problems of the web by 1997 :)

If God had meant you to get it right the first time, He would not have put "alter table" into SQL. If fixing bugs and adding features to online systems handling 20 hits a second were easy, you would not be getting paid $1,250 a day.

Miguel explains a little of the legal background to the collaboration between Microsoft and Novell on Silverlight for Linux. Later on the thread it does get into a tedious unrelated debate about OOXML, so don't read that :)

We are obtaining covenants (from Microsoft) and patent licenses (from
MPEGLA, the consortium of American, European and Asian companies that own
the "media space") to be allowed to redistribute Moonlight with a minimal
risk to the end user.
I say "minimal risk" and not "risk free", because that is the nature of
software patents, we could be infringing a patent from some guy in Latvia
for walking a linked list.
So that is the approach that we are taking to distribute for commercial use
Moonlight, a plugin that operates in the media space: a patent rich and
incredibly profitable space for the patent holders. The rights negotiated
will give anyone patent coverage, as long as it is downloaded from Novell.
Although I would like to fix the patent system, am not the one going to do
so. It feels like boiling the ocean
