Digitale Signatur mal wieder

Heute hat mich ein Kollege zu einem signiertem PDF befragt: Ist das korrekt und qualifiziert unterschrieben?

Sind wir mal naiv und öffnen es mit Acrobat X. Ja, ist signiert, kann das aber nicht überprüfen. A-Trust tools sind installiert; ein update auf den aktuellen download von a-trust ändert nichts dran, dass ich von dem Teil nur Fehlermeldungen bekomme.

Ok, gut, wozu gibt es einen Online-PDF checker unter https://www.a-trust.at/pdfverify/. Nix da:

Nur gut, dass die RTR bessere Arbeit abliefert: Der Online-Validierer unter https://pruefung.signatur.rtr.at/ funktioniert.

Sandman, send me some dreams

An evening with two other kids at home: Cooking for the whole pack and then watching the sandman on tv together.

Murphy’s law

I was invited to give a talk at Donau-Uni Krems and was wondering whether to take the train or drive myself by car. I chose the train.

Big mistake: electrical problems between St. Andrä-Wördern and Tulln, thus we’re delayed for a long time.

I should have stuck to the original plan of taking the car and scoring a crate or two of wine.

Tracks

We haven’t built a new set of tracks in a while, but yesterday Clemens and I made one, this time in the children’s room. It thus takes two pictures to show it all:

Adobe Madness

I finally bit he bullet and upgraded to Reader 10.x to get the security benefits of the sandbox.

But:

  • Why this f*cking bloatware of the Download Manager as a Firefox plugin. WTF?
  • And why do these bastards try to sneak in McAfee software? I did not see the checkbox.

See also this thread in the Adobe forums.

Way to go, Adobe. Do you really think pissing of customers, especially security professionals is good company policy?

Dummheit bei der Telekom

Ametsreiter in der Fuzo:

Der Einsatz von “Deep Packet Inspection” (DPI), mit der der Netzverkehr durchleuchtet werden kann, sei eine Angelegenheit des Betreibers, wird Ametsreiter im “Wall Street Journal” weiter zitiert. Kaufe eine Fluglinie eine Boeing 777, schreibe ihr auch niemand vor, wen sie damit befördern dürfe.

Die Analogie ist super, darf ich die auch mal hernehmen?

Kauft ein Endkunde einen Internet-Zugang, dann schreibe ihm auch niemand vor, welche Applikationen er darüber nutzen dürfe.

Wie wär’s damit, Herr Ametsreiter?

Airport <-> City connections

I’ve been on two business trips over the last weeks and I noticed the following:

Barcelona: Express Bus service from the Airport to the city center every 5-10 minutes.

Stockholm: Arlanda Express every 15 minutes.

Vienna: CAT every 30 minutes.

I do see some potential for improvements here for Vienna.

Offline plugin for DokuWiki

I’ve been trying to adapt the offline plugin to our needs. Here are my changes:

offine.diff

Caveats:

  • It clashes with how “datadir” is set in the example in the security page. That field must not contain a trailing ‘/’.
  • The plugin should remove the .zip file before adding files to it to avoid obsolete files accumulating there.

YouTube via IPv6

I don’t know whether my still-not-quite-native IPv6 at home is to blame, or whether Google has some capacity problems over v6, but watching youtube videos at home with v6 enabled offers a significantly worse user experience, than via v4.

Dear FedEx

Last year, we had troubles getting spares delivered via UPS.

This year I ordered a book from Blurb and FedEx was the carrier. This time, it was addressed to my flat in Vienna. The tracking info sounded all right, up to the first missed delivery. They were definitely trying as the delivery guy left a note on my mailbox.

I filled out the note (yes, delivery to any neighbor is ok) and put it back. Eight days later, it is still there, and the tracking page lists a number of tries:

We were at home. I never left my flat 24th – 26th. And the last two days we had sick kids at home.

Why can’t these companies be honest and admit that they failed to come?
