Python HTML Scraper
„A simple HTML ‚parser‘ that will ‚read‘ through an HTML file and call functions on data and tags etc.
Useful if you need to implement a straightforward parser that just extracts information from the file *or* modifies tags etc.
Shouldn’t choke on bad HTML.“
Nützliche Mac Software

Sehr schön – da ist einiges dabei was ich noch nicht getestet habe 🙂

Improve PHP performance try php __autoload()
„Of all magic in PHP I probably like the __autoload() hook the most. It saves a good deal of tedious script inclusion calls and may drastically speed up your application by saving the parser from doing unnecessary work. Allthough it has been around since the release of PHP5, I haven’t found any convincing applications for it yet. Most of them follow the same scheme: Whenever an undefined class is being instantiated, a little __autoload() function tries to include a PHP file, which has to be named after it’s class:“

„Das SANS-Institut hat heute seine Liste der 20 am meisten ausgenutzten Sicherheitslücken des Jahres 2005 veröffentlicht. Überraschungskandidaten sind Antivirensoftware, Cisco-Produkte – und Mac OS X. Die tradierten Kategorien Windows und Unix reichen inzwischen nicht mehr aus, neu hinzugekommen sind die teils umfangreichen Kategorien Cross-Platform-Anwendungen sowie Netzwerkprodukte.“
Passwort eines PostgreSQL Benutzers / Role resetten
Falls man mal in die Verlegenheit kommt, das Passwort eines Benutzers bzw. einer Role in PostgreSQL zurücksetzen zu müssen, hier eine kleine Anleitung:
- Authentifizierungsmethode in der pg_hba.conf für den Root/Admin-Benutzer für Localhost auf Trust setzen (Beschreibung)
- Über den Localhost mit diesen Benutzer auf die DB connecten
- Passwort ändern mit „ALTER ROLE user WITH PASSWORD ‚password‘;“ (Beschreibung)
- Authentifizierungsmethode in der pg_hba.conf wieder zurücksetzen (Beschreibung)
Sollte man das Passwort des Root-Users noch wissen, kann man natürlich gleich mit ALTER ROLE das Passwort des betroffenen Users ändern.
PHPit – Totally PHP & Ajax – PHP without using the XmlHttpRequest Object
„Ajax is one of the biggest ‚discoveries‘ in the past year, and it has become a real buzzword, just like Web 2.0. Admittedly, Ajax can be used for a lot of things, and it really does speed up web applications. Already Ajax is used by many highly popular websites, most notably GMail, but other’s like Ta-da List or Flickr also use it. Heck, even Microsoft has gotten wind of the Ajax buzz, and is actually moving towards web-based applications as well.
But there is one problem with most of the current implementations of Ajax: it has one dependency, and that is the XmlHttpRequest object. Most modern browser, like Firefox, have inbuilt support for this object, but older browsers, like Internet Explorer 6, don’t have native support for this object. Luckily, IE 6 does support it, but it’s built in as an ActiveX control, which means your visitors get an ugly warning message about the possible danger of an ActiveX control, or in some cases it just doesn’t work at all.
In this tutorial, I will show you how to use Ajax without even having to use the XmlHttpRequest object.“
