Extend SQLite with Delphi functions

I have a couple of open source projects on the go, one of which is a simple Delphi wrapper for SQLite. Lukas Gebauer has now added experimental support for user defined functions. This lets you in effect extend the SQL understood by SQLite to include your own custom functions, written in Delphi.

To try out

Interesting note in Duffy’s blog about PDC 07 (the one that never was):

Note: some might wonder why we released the articles before the CTP was actually online.  When we

Zoho users logging into other accounts by accident

Zoho users beware. There appears to be a nasty bug whereby a user logs in with their own credentials, but finds themselves logged into another user’s account:

I have the last couple of weeks experienced that I get logged on into another account that I do not know! I can see the other account documents.

Zoho CEO on Flash vs Javascript

Zoho is an online office suite. I was interested in comments from Zoho’s Sridhar Vembu on why it is coded using Javascript rather than Flash. He gives five reasons:

Web standards. “Flash, for all its advantages, sits in a separate space from the browser.” Open source libraries more widely available Vector graphics can be done

Performance testing Vista: misleading reporting of inadequate tests.

Is Vista really half the speed of XP? That is what CNET reports here, in an article which does not bother to link to the source of the tests, as far as I can see.

The tests seem to be based mainly on scripting Office through OLE automation. This is certainly interesting, but it would

Buzzword gets word count, easier sharing

Adobe’s online, Flash-based word processor has been revised and now includes word count, handy for journalists and essay writers:

It also has easier sharing: simply copy the URL at the top of the document you are editing to create a link. I intended to demo this here; but cannot because Buzzword does not

Vista myths and reality

CNET’s inclusion of Vista on a list of top ten terrible tech products has drawn some attention. Here’s the blurb:

Its incompatibility with hardware, its obsessive requirement of human interaction to clear security dialogue box warnings and its abusive use of hated DRM, not to mention its general pointlessness as an upgrade, are just some

Mobile data taking off at last

Excellent article from ARC on mobile data trends, mentioning that Vodafone has just reported a 50% jump in data traffic:

It is the culmination of attractive data pricing, improved usability and mobile demand for Web 2.0 services which is brewing to form the prefect data storm. As data pricing erodes along the same path travelled

.NET Framework for Symbian

Red Five Labs has announced its implementation of the .NET Compact Framework for Symbian, the operating system used (most of the time) by Nokia.

It is currently in beta, and implements only version 1.0 of the Compact Framework, but nevertheless it is an intriguing development.

With this, Mono, Moonlight, and Microsoft’s own implementation of Silverlight

CodeRage II: Windows only, login problems

I was surprised to learn that CodeGear’s online conference is apparently closed to Mac users, or anyone not on Windows:

That’s odd, since the company has Java and Ruby development products that run cross-platform.

Further, even Windows users have had problems logging in. The conferencing software CodeGear is using is limited to 1500
