Good PHP online shop for money

It is nearly impossible to compare the advantages and disadvantages of online shop systems because they are complex systems with a variety of functions, that build for different needs. I’m talking about such a system for small and micro-businesses, where processes can be built around the functionality of such systems to some degree. So this post can be only my personal impression of a system that I compared so far....

Will new Java Browser Plug-in make java applets sexy again?

Everybody knows the drawbacks of Java Applets. Long loading times, browser freezing, and stability problems. That fact does not make java applet popular1. Most of those problems lie in the quality of the java browser plug-in itself, which was not really good and was not improved over a longer time. Sun has ground up rewritten the browser java Plug-in. Following was done in this rebuild. Improved scripting support (So javascript integration is better) Improved reliability Supports more powerful applets (applets can ask for more memory) Better windows vista support (signed applets) Enterprise features (run one applet in a particular JRE version) The last point sounds very interesting to me....

Curiosity: How IDE features affects design quality

Don’t believe that? Than listen to the story… Occupational i deal with people who works with already aged version WSAD IDE (Rational Application Developer for Web Sphere).

Triggers appeared for assuring and extending the control of integrity property in Database Systems: … Database Trigger is predefined database procedure, conditionally or unconditionally succeeding or preceding other database operations automatically…[IBM Research Report, RJ1820, 1976] The question That is actually what technically DB Triggers are still today.

I was hacked...

Maybe you notice the downtime of this site last days. Unfortunately it was hacked by someone for unknown purpose. The attacker used some exploit in Wordpress or some plug in or maybe the problem in k2 wordpress theme. Some malfunction of these open source components was used out, so that attacker have added lines like echo passthru($_GET[1]); to some of php files. That gives them access to shell of my user account on this server....

Changes in HTML5

Yesterday W3C has published document named HTML5 differences from HTML4. Interesting here is that the standard provides two syntax variants HTML5 and XHTML5: HTML5 - is compatible with HTML4 and XHTML1 documents published on the web, but is not compatible with the more esoteric SGML features of HTML4. Documents using this syntax need to be served with the text/html MIME type. HTML5 also defines detailed parsing rules (including “error handling”) for this syntax which is largely compatible with popular implementations....

Home Page v 3.0

Now i’ve changed my homepage ultimately! From now on, my main content is blog content and all other things will be arranged around it. I’ve made some permanent redirection (301) rewriting rules so Google crawlers and browsers should not have problems to deal with changes. But i’m not sure about your feed readers. In any case every content from old path http://alexander.holbreich.org/blog/ was moved and redirected to http://alexander.holbreich.org/ including rss feeds....

"NoFollow" considered harmful

“nofollow” Background The rel="nofollow" html attribute was initially proposed by google and was supported by MSN and Yahoo! The intention was to stem spam-links, that can largely occur in some webpages, especially blog comments. The famous blog engines founded that idea very cool and most of them are setting the nofollow attribute out of the box. WordPress does it by default too. But like many of good-mentioned ideas can lead to some not wanted problems....
