On October 8-9, 2012 we were glad to attend the tele-TASK Symposium at the Hasso-Plattner-Institute in Potsdam. It was the 6th event of the series, where practitioners and researchers came together to discuss innovative technologies and methodologies for online learning.
Typography plays a big role in graphic design and can be one of the hardest things to get right. My aim here is to introduce some of the basics and the most
Social media isn’t really “new.” While it has only recently become part of mainstream culture and the business world, people have been using digital media for networking, socializing and information gathering - almost exactly like now - for over 30 years:
More than 550,000 miles of undersea fiber-optic cable wrap around the globe to deliver e-mails, Web pages, other electronic communications and phone calls from one continent to another at the speed of light. As cables make landfall, they connect to landing stations that route the voice, data and Internet traffic to domestic networks or forward the signal to another undersea network that carries the data onto their final international destination.

Today for us it's pretty normal that electricity can be transmitted on a wire, because it's part of our daily life. But, in the early 18th century, when the English nature-scientist Stephen Gray was able to show that electricity really can be transmitted on a string of copper, it was an unheard-of revelation.
On February 24, 1709, French inventor and artist Jacques Vaucanson was born, who is best known for the creation of impressive and innovative automata and machines such as the first completely automated loom.

Die mit IPv4 möglichen vier Milliarden IP-Adressen sind weitgehend aufgebraucht, neue werden nur noch durch Recycling geschaffen oder aus "Lagerbeständen" beschafft. Die Knappheit kommt beileibe nicht überraschend. Seit vielen Jahren gilt IPv6 als die nächste Generation des Internet-Protokolls, die mit der Platznot gründlich aufräumt und obendrein Erleichterungen bei Rechnerkonfiguration und Betrieb bringt.
