Startup Weekend RheinMain 2012

Img

Am Wochenende rund um den 1. Juni 2012 fand im FIZ in Frankfurt das erste Startup Weekend hier im RheinMain-Gebiet statt. Ich hatte mich schon frühzeitig angemeldet um mit meinem Projekt re:text dort teil zu nehmen. Ziel eines Startup Weekends ist es, für neue Ideen Mitstreiter zu finden und bereits am Wochenende diese Idee zu einem tragfähigen Konzept auszubauen. Hierzu stellt man in einem 60-Sekunden-Pitch die Idee vor allen Teilnehmern vor, in der anschließenden Abstimmungsphase werden von jedem Teilnehmer drei Punkte an seine Lieblingsidee vergeben. Die Ideen mit den meisten Punkten dürfen dann am Wochenende bearbeitet werden. An dieser Veranstaltung waren etwa 120 Teilnehmer anwesend, die sich zu 15 Teams zusammenfinden sollten – am Sonntag sind davon zehn Teams übrig geblieben. Über das Wochenende stehen den Teams erfahren Mentoren zur Seite, die diese bei

CZDS Security Disclosure (2014-12-17)
ACTION REQUIRED: CZDS Security Disclosure
ICANN is investigating a recent intrusion into our systems. We believe a
“spear phishing” attack was initiated in late November 2014. It involved email
messages that were crafted to appear to come from our own domain being sent to
members of our staff. The attack resulted in the compromise of the email
credentials of several ICANN staff members.
In early December 2014 we discovered that the compromised credentials were
used to access certain ICANN systems including the Centralized Zone Data

Ein kleines Weihnachtswunder: DeinBus.de gerettet

Lieber Vorname,

welch ein aufregendes Jahr für DeinBus.de und den Fernbusmarkt.

Ein für uns schwieriges Jahr, das es schon in den ersten 10 Tagen des Januars in sich hatte: Die Verbraucherzentrale meldete sich im Zuge des großen "Fernbustests" und verlangte deshalb Änderungen in unseren Buchungsbedingungen (auch, wenn wir hier sehr gut wegekommen sind). Zeitglich mussten wir nach nur sehr wenigen Betriebstagen die gerade gestartete Linie Hamburg-Leipzig wieder einstellen, weil eines der durchführenden Busunternehmen in finanzielle Schwierigkeiten gekommen war. Eine Verkehrsbehörde meinte, einen Fehler auf unseren Fahrscheinen gefunden zu haben und droht mit einem Rechtsstreit. Auch unsere damalige Hausbank war sich nach dem Umzug in die Firmenkundenabteilung auf einmal unsicher, ob sie uns als Kunde halten wollte und führte Zahlungen nicht mehr wie gewohnt durch, weshalb wir eine neue Bank suchen mussten.

Es waren so viele Hiobsbotschaften, dass Alex das Buch Hiob las.

Auch im Team gab es Veränderun

Can 1 millisecond latency be achieved?

Achieving the sub-1ms latency rate identified as a technical requirement for 5G necessitates a new way of thinking about how networks are structured, and will likely prove to be a significant undertaking in terms of technological development and investment in infrastructure.

Despite the inevitable advances in processor speeds and network latency between now and 2020, the speeds at which signals can travel through the air and light can travel along a fibre are governed by fundamental laws of physics. Subsequently services requiring a delay time of less than 1 millisecond must have all of their content served from a physical position very close to the user’s device. Industry estimates suggest that this distance may be less than 1 kilometre, which means that any service requiring such a low latency will have to be served using content located very close to the customer, possibly at the base of every cell, including the many small cells that are predicted to be fundamental to meeting densification requi
