  • Wie Funktionieren Suchmaschinen?
    Schriftenreihe der Abteilung "Organisation und Technikgenese" des Forschungsschwerpunkts Technik-Arbeit-Umwelt am WZB FS II 98-104 Reisen ohne Karte Wie funktionieren Suchmaschinen? Von Tilman Baumgärtel [email protected] Institut für Sozialwissenschaften Fachbereich Umwelt und Gesellschaft, TU Berlin und Wissenschaftszentrum Berlin für Sozialforschung GmbH (WZB) Reichpietschufer 50, 10785 Berlin Telefon (030) 254 91 - 0, Fax (030) 254 91 - 684 Zusammenfassung Suchmaschinen sind die Eingangstore zum Internet. Doch obwohl Netz-User die Suchmaschinen bei fast jeder „Surftour" benutzen, wissen nur die wenigsten ihrer Nutzer, wie sie funktionieren. Dieses Papier geht der Frage nach, ob die zentrale Position von Suchmaschinen im Netz auch zu einer Zentralisierung des Internet fuhren kann. Durch eine detaillierte Darstellung der Funktionsweise der Search Engines wird gezeigt, daß sie nicht pauschal als Instanzen betrachtet werden können, die dem „unstrukturierten", „hierarchiefreien" Internet ein Zentrum und eine Hierarchie aufzwingen. Technische Einzelaspekte erscheinen jedoch trotzdem problematisch: Besonders Suchmaschinen, die - wie Lycos - die angebliche Beliebtheit einer Site zum Maßstab ihrer Beurteilung machen, tragen dazu bei, im Netz eine hierarchische Gliederung zu voranzutreiben. Abstract Search Engines are the entrance doors to the internet. But despite the fact that net surfer use them almost every time they go online, most of them don't know how they actually work. This discussion paper addresses the question, whether the central position of search engines can lead to a centralization of the internet. A detailed technical analysis of the search engines leads to the conclusion that they cannot simply be considered as the main authorities that impose a center and a hierarchy on the supposedly „unstructured", „non-hierarchical" Internet.

  • Why Websites Can Change Without Warning
    Why Websites Can Change Without Warning WHY WOULD MY WEBSITE LOOK DIFFERENT WITHOUT NOTICE? HISTORY: Your website is a series of files & databases. Websites used to be “static” because ​ there were only a few ways to view them. Now we have a complex system, and telling your webmaster what device, operating system and browser is crucial, here’s why: TERMINOLOGY: You have a desktop or mobile “device”. Desktop computers and mobile ​ ​ ​ devices have “operating systems” which are software. To see your website, you’ll pull up a ​ ​ ​ ​ “browser” which is also software, to surf the Internet. Your website is a series of files that ​ ​ needs to be 100% compatible with all devices, operating systems and browsers. Your website is built on WordPress and gets a weekly check up (sometimes more often) to ​ ​ ​ see if any changes have occured. Your site could also be attacked with bad files, links, spam, comments and other annoying internet pests! Or other components will suddenly need updating which is nothing out of the ordinary. WHAT DOES IT LOOK LIKE IF SOMETHING HAS CHANGED? Any update to the following can make your website look differently: There are 85 operating ​ systems (OS) that can update (without warning). And any of the most popular roughly 7 ​ ​ ​ browsers also update regularly which can affect your site visually and other ways. (Lists below) ​ Now, with an OS or browser update, your site’s 18 website components likely will need ​ ​ updating too. Once website updates are implemented, there are currently about 21 mobile ​ devices, and 141 desktop devices that need to be viewed for compatibility.
