PyLinda

The Linda implementation in Python is progressing well and can now work with multiple servers (good for failover situations) and has some of the newer features that were discussed for Linda. Very interesting for distributed applications that need shared data. Eventually I'll need to marry this with the Toolserver Framework for Python. If you don't understand any of this right now: no worries, it's only interesting for programmers. Here's the original article.

Upcoming Qonos Scientific PDA

The company Hydrix (apparently consisting in part of former HP RPN calculator developers) is working on a calculator based on Linux and using open source software for the tasks. Very interesting - it's supposed to come out at the end of this year. Let's see what it actually turns out to be.

Mark Lentczner's Journal

Ouch. A periodic table of Perl operators. Could it be that someone went a little too far with the definition of possible operators in Perl? Just a tiny bit? The original article is here.

Syndication formats cause of progressive dementia?

Who wants to know what a typical civilized discussion about syndication formats looks like should just follow the link. Surprisingly, Dave Winer behaves very orderly in that thread. The same cannot be said for Mark Pilgrim. Quite amusing - ultimately, what I suspected back then comes to pass: if it's good for nothing else, the Atom format at least makes for a great network psychology experiment. On the technical side: Atom is poorly designed. The louder Pilgrim and his Pilgrim-Fathers-of-Atom-Format shout, the more embarrassing the whole affair becomes. During the discussion about the Atom API, criticism was frequently expressed that PUT and DELETE as HTTP verbs were unusual and often not supported. The comment on that was that these people should just throw their toolkits away if they couldn't handle standard techniques. At the same time, these same people specially invented their own authentication scheme for HTTP just for Atom, which merely reinvents the technique of Digest Auth under a different name and with different syntax - arguing that many toolkits and server technologies don't support Digest Auth. Yes, that's right, the exact same argument was used by Pilgrim and company in two opposite directions. So much for consistency of argumentation.

Another example: there's constant harping on how consistent the Atom format is with respect to tags. Curiously though, while all links in the format are mapped via the Link tag (and specified with corresponding rel attributes), they define three different tags just for date specifications - even though a single Date tag with rel attribute for the type of date would be far more logical in this context.

Also amusing was the discussion about the type of API - many wanted an XMLRPC API, simply because RPC integrates well into programming. What prevailed was the document faction, who prefer an API with REST structure (because documents are natively managed there via GET/POST/PUT/DELETE). Fair enough - I can accept that. But embarrassing was the manner in which various REST proponents tried to argue why XMLRPC wouldn't work. Which is rather silly given the widespread use of XMLRPC for all kinds of purposes. And for someone familiar with RPC-style APIs, the whole discussion was more of a staircase joke than a serious technical discussion. How old is RPC as a programming technique in the Unix environment? 20 years? But of course that's all just imagination...

Well, what can you expect from people who take the fact that Googlegroups and Blogger all forcibly received Atom feeds as the basis for claiming that Atom is already more widespread than RSS today? Now can you understand why it's really no pleasure to deal with content syndication? Only psychopaths and cranks in that field, hardly a mentally normal person to be found. Can someone now explain to me why I programmed my own aggregator for the Python Desktop Server? Here's the original article.

Web Development Bookmarklets

Lots of nice bookmarklets (small JavaScript snippets that can be triggered via bookmarks) for web developers. The named anchor one is particularly handy - it makes anchors in text visible so you can link to them. Without this bookmarklet you're left digging through the source code (or possibly CSS hacks). Here's the original article.
