Fighting the War – Chaosradio

This wednesday I will be in the Chaosradio show at radio Fritz with Pavel, Peter Glaser und Tim .

We will try to lift the “We lost the War”-debate to a new level. Hopefully, Rop will join in by telephone. Pavel has written an optimistic answer to our scenario and I am rather happy to talk with him live on air/net, as our debates tend to be rather productive and fruitful (and hopefully fun to listening too). Peter Glaser is certainly one of the most insightful authors of our time when it comes to all things digital and I am really happy that he finds the topic worthy enough to participate.

There is a wiki page to participate , and it also lists the coordinates where and how the show can be received. Multiple streaming formats are available, podcast too later on. The show will be in german, but if all goes well there will be blog entries on multiple places reflecting it in english.

Euro counterfeit statistics update

The euro counterfeit business seems to be rather adaptable. Now that 100 and 200 € notes are looked at with suspicion by most merchants for a long time and the 50€ note has become (rightly so) also kind of suspect, the move seems to be into the 20€ and a bit into the 10€ note. While the 50€ seems to be still the sweet spot due to its good balance between high volumes in circulation which minimizes the scrutiny that a merchant spends on one note, the 20€ is clearly up and coming. So watch out for counterfeit 20€ notes. Also notable is that the 500€ note (I can not remember to ever have seen one in the wild) seems to gain popularity. If you do the math, it makes sense. If you can make a good 100€ or 200€ note, the step to 500€ is not that large in terms of production cost. But the gained net value is five times or 2.5 times as high. Still no reliable data on planned introduction of RFID tags into the money, which will open new opportunities to counterfeiters.

Data Source: ECB

PS: the total value of confiscated counterfeit euro notes is still at the peanuts-level: 15.229.500 €

Digital Photography Data Rescue

Nothing impedes the joy of digital photography more then defective memory cards. Today, while trying to make a small movie while skidding down a nicely snow covered hill in a park, the dreaded Memory Card Error blinked on the display.

Of course, I tell everyone who asks that you should write new memory cards full with data multiple times before you can trust them. The reason is that the Flash memory used in these cards has usually defect areas. To compensate that, there is more memory hidden on the card then what is written on the label. When a memory block shows signs of defects, the on-board error correction of the memory card internally uses a block of the excess memory instead of the defective block. Writing the card full with nonsense data multiple times makes sure that the usual early defects are recognized and mapped out, before you put any important stuff like your pictures on it. You can think of it as a sort of “burn in”, like a new car that needs a certain milage before the motor is considered to be fully performing.

Naturally, I had not done this “burn-in” with the card in question. Now it did not wanted to be read either through the camera nor through an SD-card reader. After a bit of experimenting, I succeeded in recovering most of the images and movies with the following procedure:

First, I used the camera-internal format option multiple times, until the camera no longer complained about the card error. This was needed to get the card into a state where the computer would recognize it again as a readable memory card. “Formating” on nearly all cameras does not really erase the pictures, but merely deletes the references to them in the file system. Then I used the trial version of PhotoRescue to determine if there is data worth paying for left on the card. PhotoRescue is made by Datarescue, the company that also makes IDA Pro , the worlds premier tool for disassembling and software reverse engineering.

To my great joy, PhotoRescue found all the images and most of the movies, except the one that got written onto the bad memory block that triggered the problem in the beginning. Fair enough. The trial version lets you see everything that can be recovered. So happily spent the 29€ for the tool that saved my day and recovered all the images and most of the movies.

Delete your Orkut accounts – Now!

Google is getting evil. We all knew it would happen, but now is the time. Orkut (googles social networking service) now forces every user to associate the account with an Google Mail account. The ultimate data treasure trove. You not only getting the social network nicely mapped, you also get all the content! Probably in one database! How convenient. Googles old motto “Do no evil.” has apparently been deprecated. Censorship for chinese users, sustained rumors about intelligence ties etc. pp.


orkut Help > My Account > Upgrading to a Google Account New!

After converting my orkut account to a Google Account, will my use of orkut be associated with my use of other Google services?

We may use information from your converted orkut account for other Google services in order to improve the quality of those services, for research and analysis, and to provide you with a seamless experience between our services. .

Probably Orkut will real soon now be able to flag who your friends are by just conveniently analyzing your e-mail. So you no longer need to decide, the nice OrkutGoogleMail will help you.

I am just trying to find out how to delete an Orkut account without associating it with an gmail account, I will report here on the associated problems. If you happen to have an Orkut account, delete it now and demand proof that the data has been deleted. And ask them too how to do that without having a gmail account, so they will explain it upfront.

Airborne blogging

Note to non-german readers: traditionally, I do travel blogging in german.

Location: N 62.46 E 01.45, Nordatlantik, westlich von Norwegen
Höhe: 10363m, Geschwindigkeit 777km/h über Grund

Ich finde das 21. Jahrhundert gerade supertoll. Dieser Eintrag ist live von obiger Position, aus einem Flugzeug. Connexion heisst der Service, WLAN im Flugzeug mit Satellitenanbindung. Funktioniert einfach. Ich habe noch nie lieber 29 Dollar für 10 Stunden Netz ausgegeben.

SAS als Fluggesellschaft sammelt gerade massiv Pluspunkte bei mir, sogar die Holzklasse ist hier (moderner dicker Vierstrahl-Airbus) erträglich. Das Essen taugt auch im Rahmen des Möglichen.

After the war

Today, I finally found the time to read up on all the blog and news comments on the We lost the war – Welcome to the World of tomorrow talk Rop and me held at the 22C3. As we intended, people got provoked, outraged, thinking, debating, accusing us of this and that, questioning our analysis, making suggestions what to do. We even got some slightly fossilized know-it-alls provoked enough to comment in blogs and news. This is good.
Of course not everyone understood the talk as we wanted it to be understood: a call to wake up, not an declaration of capitulation. This is unfortunate, but we needed the provocative title to get peoples attention.

Apparently, some people stopped listening after the first part, where we discussed the state of the world. This state is depressing, no doubt about that. Getting it all compressed into 15 minutes may be more then you wanted to hear on a long dark winter night. (Knowledge brings fear, remember?) But we need to face the realities to be able to look forward. If we take a long hard look into the crystal ball, using our intimate grasp of technology to predict how things will develop, and act accordingly, we have actually a very good chance to survive and thrive as a techno-social culture that can change things for the better and offer alternatives and options that would not be there without us. If we stumble on without understanding where the journey takes us, we risk to loose that chance.

Sure, using the term “they” to describe those in power is debatable and wrong, especially if you like your marxist-leninist or other political science flavor of fine-grained political analysis. But if you want to concentrate on the overall effect of technology and the security-intelligence complex on society and, more important, want to talk about how to prepare for the worst to come, it is justified to abbreviate. For this one goal I preferred for once a catchy “they”, instead of boring my audience to death with org-charts of the current power structures and their interdependencies.

What is certainly correct is that we need to talk about the complex relationship between techies and power. The borders are fluid. The way into a position where you can suddenly seriously influence things and get sucked into the logic of power and interest groups and realpolitik is sometimes shorter then many might imagine. Suddenly perspectives change, ethical hurdles become relative, goals shift. We need to talk about this phenomenon, especially as many of us reach a certain age where the chance to end up “inside the system” is really high. I have no good suggestions, except to try to remember where you came from, and reflect on your new goals and ideals, if they are for real and not just forced onto you by the situation.

I did not want to destroy the optimism of those who believe that blogs will save us from the evil entertainment industry powers, that podcasts will bring us eternal freedom from state-controled/controling news monopolies and that lobbying and media work can still change politics for the better. I just seriously doubt that all this will help us, once full scale surveillance and automated selective prosecution have been established, which will be the case within a few short years. Without a working set of technical solutions to preserve a breathing space, chances are that there will be little freedom left to be defended. We are the ones that need to provide this technical breathing space to the political activists.

As Rop said at the closing ceremony: We face a situation where technology has passed the point where there is any chance of toppling a dictatorship that comes into possession of all the new tools. Preventing a dictatorship from happening is no longer a theoretical exercise, but the highest priority.

You may not agree with our analysis. You can certainly point out a number of points that we forgot or ignored. You may think we are depressed doomsday prophets that neglect their own successes. You may even find it all defeatist and boring. But please keep one thing in mind: we might be right. Better to debate where to focus our energy now effectively, then just stumble along and hope that everything will be ok, somehow, magically. So lets talk.

Erstaunliches aus der Lebensmittelindustrie

Gerade begegnete mir etwas geschmacklich eher erstaunliches. Den Aromapanschern bei Coca-Cola ist mit ihrer “Lift Active” Apfelschorlesimulation plus Grapefruit-Extrakt etwas wirklich einmaliges gelungen. Das Gesöff schmeckt kalt und im Originalzustand ganz erträglich (im Gegensatz zur originalen “Lift Schorle”, bei der das zu Tafelwasser umgetaufte harte Leitungswasser zu sehr durchschmeckt). Wenn man aber den Imperialistenbrause-typischen Kohlensäureüberschuss aus “Lift Active” durch ein bischen schütteln reduziert, wandelt sich der Geschmack zu dem von original Ost-Brause ! Genauer gesagt ist das Erlebnis sehr ähnlich der damals durchaus trinkbaren gelblichen “Limonaden”-Variante, die es, meist in Bierflaschen abgefüllt, vorzugsweise ausserhalb Berlins gab. Ich habe leider das alte Etikett nicht mehr so recht identifizieren können, aber eines der hier gelisteten müsste es eigentlich sein. Die deutlich süssere rote Limonade war damals eher nicht so mein Geschmack, obwohl sie auch Liebhaber hatte.
