There are Open Source projects that claim to be able to convert PDF files to HTML. See, for example:

• pdftohtml
• pdf2html

None of the tools which I have come across and tested appears to work in a satisfactory manner. It appears that a L^AT_EX (or equivalent) source is required; then, tools such as L^AT_EX 2html or L_yX2html can be used with great success.

Personal experience has shown that commercial Windows products will not do a good job either. Needless to mention, screenshots of pages are out of the question because they neglect to treat text properly. That is probably why PDF is not truly open (yet it is secure) and feelings about it are somewhat mixed.

On the contrary, many tools exist for converting HTML (which is open) into PDF. See a Google survey to convice yourself that it is so.

A one way conversion is always a bad thing

This short publication about the History of PDA‘s presents a nice pictorial collage of devices, from the very early days until the emergence of the Palm Pilot.

Few days scare me more than those when I return from a vacation (as in yesterday). I take certain measures to ease the pressure, e.g.:

• Mail auto-responder/s are set up to suppress incoming messages
• Wikis for correspondence (IM equivalent which updates a few times a day) are locked or put on hold
• Disappearance from Web logs and forums
• No involvement in newsgroups and mailing lists

Despite all, E-mail, newsgroups, and feeds require catching up upon return. Even worse, additional reasons to worry lurk around the corner:

• One can forgot what has recently happens in the field of IT
• Orientation within API‘s gets eroded
• Breakage of Web sites or pages
• Shortage in updates, resulting in reduced crawling
• Electronic moderation, approval, and authorisation are delayed
• Site spam in its various forms
• An extensive list of tasks which cannot not be handled remotely
• Backups which are long-overdue

So, moments after a vacation are perhaps good moments to stay isolated… and catch up.

My sister had no worries about comment spam

any different forms exist for conversation over the Internet: site forums, wikis, newsgroups, IRC, blogs, mailing lists, IM and so forth. Each of these requires an application to be accessed — a Web browser being the most common among these applications.

The different communication methods have pros and cons, but they all can be bridged. All should be intrinsically entwined. Commercial interests have often pushed conversation protocols apart and disintegrated them to form the chaotic state we are in today. The result: poor compatibility, inter-operability and an endless number of installed applications, all of which are needed in order to keep up with the changing times (and people).

Will somebody, once and for all, take initiative and work towards a single comprehensive package?

Feeds have come a long way towards efficient,
standardised form of one-way communication.

Shortly after Adobe’s acquisition of Macromedia, Microsoft infiltrate Adobe territories by introducing their own portable document format called “Metro”, which is based on XML.

Services that manage lists of tasks on-line spread rather quickly. Matt Mullenweg recently announced:

Someone cloned all of Ta-da List into Bla-Blah List which uses Flash for the interface instead of HTML/JS.

I have come across similar features in recent versions of Horde (shown above). I truly believe that these tools can compete with PDA‘s, especially when content is edited in collaboration with a team. All software mentioned, by the way, is completely free.

The following screenshot gallery demonstrates the features of one future desktop environment (X11). Windows exploit OpenGL for window ‘swinging’ (see the previous entry on luminocity or even bogus transparency). The effects are quite distracting, but provide that ‘wow factor’. Another long-anticipated eye candy is the spherical desktop.
