  • Deutsche Telekom und das Internet

    Die Telekom hat offenbar ein anderes Internet, das kein IP verwendet. Oder das ist Satire.

    Im sogenannten Voice-over-IP-Verfahren (VoIP) wird bereits mittels Datenverbindung über das Internet telefoniert, etwa über die Computersoftware Skype. Ein Ersatz für den herkömmlichen Telefonanschluss ist VoIP per PC allerdings nicht, denn sie bietet vergleichsweise geringen Komfort und Verbindungsabbrüche sind an der Tagesordnung.

    Aber:

    Das ist beim Telefonieren über das Internet Protokoll ganz anders: Die Gesprächsverbindungen über IP erfolgen in hervorragender Sprachqualität und dem Kunden stehen alle Bequemlichkeiten moderner Telefon-Features zur Verfügung.

  • Exploiting the DRAM rowhammer bug to gain kernel privileges

    For the sake of having this here. Manipulating bits in memory is a big deal in multi-tenant virtualized and cloud environments, aka public cloud. Unfortunately this is a hardware issue and not something that a software patch will solve. Only new physical deployments can solve that problem. So rowhammer will be a nightmare for a while…

  • eMail. Still.

    Year 2015. Still eMail is the predominant means of communication. Everybody hates it, most companies make an effort to ban it. Atos wanted to go email free, Telekom shuts off their servers, Daimler even deletes email for people on vacation. Even I receive emails, saying “I need this, but I cannot answer”, quoting the “email free day policy”. Despite all effort, nobody succeeds.

    Why? Unclear. While I think email should be banned myself, I have difficulties offering a better option. But I develop a feeling for why this is happening. This morning somebody mentioned he’ll be posting into a slack.com channel. That company claims to simplify communication, make teamwork less painful and busy, all searchable. As if nobody else tried that. And even if slack.com does a good job in what they aim for, they are just another solution.

    In my personal, active use are trello.com, Pocket, Salesforce chatter. While my company introduces a community, colleagues swear on private Facebook groups or WhatsApp for simplified communication. Not to mention the tools customers and businesspartners are using. Popular among these are Jive, Atlassian Jira, SAP Jam, but not limited, I’ve seen self hosted communities, bug trackers and ticketing tools.

    It’s difficult to keep track of all these tools. But they all send notifications through email.

    Which tool do you use to communicate?

  • Travel a lot?

    Travel a lot?

    Don’t worry, you are not alone. German airports counted 207.934.803 travelers, in 2014. Out of all included airports in that report, the top 3 busiest airports, Airport Paris-Charles-de-GaulleFrankfurt (FRA), Munich (MUC) and Düsseldorf (DUS),  are responsible for more than half of all travelers, in total. (121.117.136 Travelers). And the numbers won’t include transit. Now consider the Munich Airport only serves all of Bavaria, which had 12.604.000 people living there in December 2013. With MUC serving 39.593.025 passengers (departure and arrival) in 2014, assuming everybody returns to where he departed, every Bavarian would fly from Erding 1.57times per year. And the trend is increasing, after the same paper from above. Obviously, there are some people traveling The tip of the Eiffeltower. Not visible: the Eiffeltower.more than others, and I do definitely give to the side north of the average.

    In times of global communication and videoconferencing means, commodity and convenience is a an argument for all business type of apps. Travel websites make it easy for customers, private and business, easy to get away. AirBnB even makes a (huge) business offering cheaper deals on privately let apartments. No traveler needs to work with a travel agency anymore. Any  traveler can arrange a trip to a Sacré-Cœur de Montmartrerandom European city by himself in minutes and spend a few hundred € max.

    In particular, business makes huge use of this commodity, for one particular reason. Policymakers regulated business very much about how business partners can close deals, for a good reason. And compliance is a huge social achievement, laying out common rules for all business. But all personal interaction and mutual appreciation cannot be outweighed by Internet, e-Mail, social media or videoconferencing. The more valuable and complex a solution Aisle on a random airplane.will be, trust is a part the decision maker will appreciate higher. That makes frequent business travel indispensable. And so are airports full of travelers that do not appreciate traveling. People that get up 5am in the morning, to fly out to a city 2 hours flight away, to make it to a 9.30am meeting, with executives from an important account. And come home by 9pm. Instead of enjoying the experience.

    Remote work cannot replace traveling, in particular for business partners. But remote work should complement travel. Business travelers should see traveling as a privilege, enjoying the destinations they are traveling too, and not an annoying duty, just to get the business done.

    How do you travel on business?
