Umfangreiche Abarbeitung der Todo-Liste für das Launching der neuen Website.
Insbesondere wurden alle englischen Geräteseiten in das neue System übersetzt (wurden vergessen), die Univac-Seiten mussten dafür auch noch umbenannt werden.
Dafür wurde auch die englische Navigation um die Extraseiten vervollständigt.

Ferner:

  • Angefangen: Hostsystem zur Implementierung des aus v5 javascript-basierten hostinfo-Systems (aber mächtiger, mit server- und clientseitigen Hooks). Findet derzeit nur Verwendung in hostspezifischer Veränderung der Template-Konfiguration, etwa auf Heriberts Computer. (Mit den momentanen Einstellungen wird das Bearbeiten auf Heriberts Computer derzeit wieder nicht funktionieren)
  • Derzeit sind (kurzfristig) alle Extraseiten im Menü sichtbar, wenn man es aufklappt.
  • Einige Bugs beseitigt (telefunken-t40w.js, etc.)

Es gibt zwei Extraseiten, bei denen die Bilder gelöscht wurden: LAB 8e und Telefunken 650. Wenn sie nicht mehr verlinkt werden, sollten die Extraseiten auch gelöscht und aus dem Menü entfernt werden.

    30     <p>If we had a list of customer names to be sorted, we would first give each customer a three digit customer number. We can then sort this list in numerical (ascending) order or sort by their names.</p>
    31    
    32     <p>If we would sort the customer names manually, the cards would initially be sorted by the 100's decimal place into 10 piles. Subsequently each of the 10 piles would be sorted by the 10's decimal place into 10 piles. Finally each of the piles would be sorted by the 1's decimal place.</p>

    38     <p>Machine sorting can not use this procedure since we would need an unlimited number of sorting compartments (pockets). Thus it sorts the other way around, from the 1's decimal place to the 100's decimal place. In summary, in each step (2-4, according to the diagram), there would be a maximum of only 10 card decks per sort.</p>
