Albatross 1.10 released

Dave Cole

OVERVIEW

Albatross is a small toolkit for developing highly stateful web
applications.

The toolkit has been designed to take a lot of the pain out of
constructing intranet applications although you can also use Albatross
for deploying publicly accessed web applications.

In slightly less than 3000 lines of Python (according to pycount) you
get the following:

* An extensible HTML templating system similar to DTML including tags for:
- Conditional processing.
- Macro definition and expansion.
- Sequence iteration and pagination.
- Tree browsing.
- Lookup tables to translate Python values to arbitrary template
text.
* Application classes which offer the following features:
- Optional server side or browser side sessions.
- The ability to place Python code for each page in a dynamically
loaded module, or to place all page processing code in a single
mainline.
* The ability to deploy applications either as CGI or via mod_python
by changing less than 10 lines of code.

The toolkit application functionality is defined by a collection of
fine grained mixin classes. Nine different application types and five
different execution contexts are prepackaged, you are able to define
your own drop in replacements for any of the mixins to alter any
aspect of the toolkit semantics.

Application deployment is controlled by your choice of either cgi,
FastCGI, mod_python, or BaseHTTPServer Request class. It should be
possible to develop a Request class for Medusa or Twisted to allow
applications to be deployed on those platforms with minimal changes.

Albatross comes with over 160 pages of documentation. HTML, PDF and
PostScript formatted documentation is available from the toolkit
homepage.

Problem With Comparison Operator <=> in G++

by: Oralloy | last post by:

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
