Statistics

These illustrations appeared in todays local Sao Paulo newspaper. The first shows the distribution and type of the attacks. For reference: the shaded city area shown is approximatelly 50km east to west, 35km north to south,inhabiting approximatelly 20mil people. So the kiling spree happened mainly in the southeast. Police is defending its actions on TV and seems to get the support of at least the middle class that lives in perpetual fear of the fevala residents. GSM around penitaries has been switched of now, based on a new law.

China News

The only english language news source on the hotel TV is CCTV9 International. Rather interesting, as it is a CNN-lookalike run by the chinese government. The world news is more or less neutral point of view, only very subtly US-critic, comparable to what you get from Xinhua on world events. The news on China is clearly reflecting the government viewpoint, focusing on chinese culture, art and achievements.

A slightly bizarre news item on the 3 gorges dam focused mainly on construction progress (of course 10 months faster then the plan, thanks to hard work and new technology) and that the dam is secure against natural disaster and (I am not making this up) terrorist attack. Voiceover on pictures of construction work on the dam: “The experts say that the dam is highly secure against terrorism. In case of a nuclear attack threat, the water can be safely discharged within 3 or 4 days.”. If I remember correct, the mass of water involved would ammount to one of the larger floods in human memory…
The CCTV9 moderators are looking chinese, but often speaking even better english then BBC anchorpersons. The weather woman is not chinese but probably of british or australian origin, for whatever reason.

Oh, and China has now its own weather channel, perfectly timed on the arrival of a serious taifun. It costs about US$1 per month for cable subscribers in China.

Back in Sao Paulo

(Trying out a new language scheme. Podcasting in german, text based travel-blogging in english. Lets see if you like it.)

I am back in Sao Paulo, Brazil for a week of work. The security situation in Sao Paulo is not funny, when you look at the media. TV and newspapers are full with discussions about police shooting smalltime criminal favela-inhabitants in revenge for the organized killing of a substantial number of police officers. Politics is reduced to more or less veiled best wishes for the police in their hunt. Apparently the local government has made a deal with the organized crime forces and police is now killing not-so-organized criminals to get revenge. It does not look like the PCC-gang that incited the killings is suffering much, probably part of the deal.

But as I said, this is all out in the Favelas. Here in the more well-to-do areas nothing is visible. I haven’t seen an armed police man after leaving the airport.

No Flickr

Recently, two people in a row asked me why I don’t put my pictures up to Flickr. Come on, everybody’s doing it…

Here is why not:

1. Every time a cool new service comes along that allows me to do something net-based that I might find interesting it ends up getting merged into some sort of über-ID scheme that wants to merge all my online data. It happened with Orkut (now googlified). It happened with Skype (now part of the evil eBay empire). It happend with Flickr (now part of Yahoo). It happened or will happen with countless other services.

With the takeovers come new rules for privacy and ownership of data that most of the time make the situation worse for the user. Additionally, having all your online life aggregated under one or only a few easily to track IDs carries a substantial privacy and security risk. I prefer to keep things separated.

2. The overall security situation of web-based applications is bad and it gets worse the larger they get. Random Jane Hacker has described the problem in detail, covering a number of aspects that may surprise you. I prefer to have knowledge and control over who does the backup, maintains the security of the system etc.

3. In principle (and reinforced by my Orkut experience), I have a healthy distrust for things ‘everybody’ is doing. Socio-technological progress is not always a universally good thing, so I try to keep some distance and wait a bit till the others have made all the usual mistakes and then take a look what is useful after the hype is over.

(Thats not the reason why there are no podcasts here, btw. The reason is that I have so little time over the day where I would like to listen to spoken word that I don’t see value in producing spoken content myself.)

Back online

The server moved again, hopefuly for the last time in a while. If you notice problems, like in the archives, please let me know.

A different Iran scenario

The question what will happen next in Iran invites to speculation. I spent some time to try to read up on some of the fine details that may shape the future events, and here is what I think may happen.

First, to understand the obsession to deny Iran a nuclear weapons capacity, the structure of the new leadership in Iran is rather important. The Revolution Guards that moved into positions of direct power in the last months after the election of Mahmoud Ahmadinejad may in one aspect be extremly roughly compared to the rise of the Siloviki , which came to power in Russia under Putin: 40-50 year old ruthless intelligence and military officers, determined to clean up the corruption mess of the previous government. The major difference: in Iran, the new elite seems to belong to a Shiite sect that believes the 12th Imam will return rather soon then later and not, as the majority of Shiites believe, sometime in the unforseeable future. The impression in the west has become widespread that this sect tends to a not strictly rational world view, to put it diplomatically, and would not refrain from immanetizing the eschaton , given the chance and the tools.

In principle, the West could probably live even with orthodox mullahs having nuclear weapons in Iran. The mullahs have proven to be relatively realistic and rational when it comes to preserve their power and survival. A certain calming effect of nuclear weapons on states foreign policy can be seen on the example of Pakistan and India. After a brief “Oh, shiny! We got new toys, lets go threaten the neighbor…”-phase, things have cooled down and come to an relatively stable coecxistence. Same with North Korea.

Unfortunately, the image of the new iranian elite makes the “lets wait and see what happens”-option a bit unattractive. I am unsure if the famous soundbites from Mr. Ahmadinejad are really as mad as they sound. Translation from farsi (corrected after comment) is a tricky thing. On one hand I can imagine that the Iranians play a clever game of twin speak and distribute toned down translations. On the other hand, I am perfectly able to imagine that translations in the west are systematically spiced up to shape public opinion. Maybe an farsi (corrected after comment) speaker can comment on that.

So given the perceived situation in the West, some sort of confrontation seems inevitable. Technically, the options for the US and Israel are a not very good at a first glance. An outright military confrontation involving occupation of Iran is not looking very attractive, given the experiences in Iraq. Mounting an air campaign against the known and suspected nuclear facilities and the countries leadership would very likely be a rather protracted and complicated undertaking and not be sufficient to prevent Iran from completing its nuclear tinkering, except if conducted in the style of an permanent air superiority with bombing going on over months. Iran can be expected to mount a much more effective defense then Iraq and strike back with asymmetric means, like attacking the oil production and transport in the region and attacking by terrorist means in the US and Europe.

Attacking the weak spots?

All this is known and discussed at length in the mainstream press. Lets look at other options the US has to force Iran to cooperate. Embargos of products critical to Irans economy are a frequently discussed option. Given the economic structure of the country, it has some weak spots where it really hurts if an embargo can be agreed on.

One of the rather surprising weak spots is that Iran imports more then a third of its gasoline from abroad. While the country has plenty of oil, it has insufficient refinery capacities to make gasoline. At least one of the refineries is 90 years old. Efforts to increase the capacity are under way , but building refineries takes years and costs billions. So a gasoline embargo plus other measures might in the eyes of US planers lead to political unrest and regime change in Iran. But enforcing a gasoline boycott to be 100% effective might prove difficult, given the political geography of the region. Iran has very active trade relationships with India, Pakistan and China. Getting these countries to cooperate on an gasoline embargo is at least an interesting challenge.

So in the long tradition of its undeclared wars, the US might choose to run an covert sabotage and attrition campaign against Irans weak spots. Taking a look at the geography , from the view of the armchair strategist desktop, this looks like a feasible option.

Most major refineries are either near the Gulf coast or near a border to a US friendly / controlled country. Sabotaging petrochemical facilities is not an trivial task, as they tend to be rather large installations, but certainly doable with the right knowledge and experience. I bet that US Special Forces have been among many other things trained for missions like this. Given the large numbers of ex-Special Forces soldiers of other nations selling their souls in Iraq, there is even the option of recruiting non-US mercenaries, thereby preserving a modicum of deniabilty.

Interestingly, it might already have begun:

In other news, a huge fire broke out in a 300,000 b/d gasoline pipeline in central Iran last week while workers were moving a section of the pipeline but damage and leakage were quickly contained, Iranian oil minister Kazem Vaziri Hamaneh was quoted Monday as saying.
“The pipeline had been moved because of heavy rain and the workers were re-locating the pipeline when they cracked the pipe and caused leakage. Unfortunately, the cracked point caught fire while they were welding it,”
Vaziri Hamaneh told student news agency ISNA. The fire had not been previously reported. The Iranian minister said there was no significant spillage. “…but it was a big fire that was put out last Wednesday evening.”
It was not immediately known if this would affect Iran’s gasoline imports. Iran, an OPEC oil producer, imported some 170,000 b/d of gasoline in 2005 to meet high domestic demand.

The explanation sounds rather made up, but thats how it sounds when a government does not want to acknowledge that its country is victim of covert warfare.

How such a campaign may look like in the news can be seen on the case of Syria. A weapons factory blows up, a shipment of missiles from North Korea gets exploded in a train collision

So looking for further “accidents” in the petrochemical and other industry of Iran might be worthwhile in the next months.

Der “Google Earth als Zielfernrohr”-Unsinn

Die Zeitschrift Technology Review , eine vom heise-Verlag betriebene Ãœbertragung der US-amerikanischen MIT Technology Review , setzt ihren Weg in die journalistische Bedeutungslosgkeit fort. Unter der reisserischen Ãœberschrift WM-Sicherheit: Google Earth als Zielfernrohr gibt Niels Boeing einem Klaus -Dieter Matschke, Inhaber einer wohl nach seinen eignen Initialien benannten Sicherheitsfirma namens KDM , Gelegenheit einen Movie Plot Threat vom feinsten auszuschwadronieren.

Über Google Earth liessen sich, so Matschke, die Koordinaten von Stadien ermitteln, in die fiese Terrorisiten während der WM Raketen schiessen könnten. „Solange Google Earth in dieser Form online ist, gibt es ein Sicherheitsrisiko.“, so Matschke.

Der geneigete Leser windet sich vor Entsetzen. Das ist nämlich eine echt krasse Gefahr wegen der man Google Earth sofort abschalten muss!

Was nun ausgerechnet Herrn Matschke (der sein Geld, ausweislich seiner Webseite primär damit verdient, schattige Ex-Geheimdienstler zu beschäftigen, die dann Produktpiraten und Wirtschaftsspionen jagen) prädestiniert, der einschlägige Experte für dieses Themenfeld zu sein, bleibt leider im Dunkeln.

Der Autor qualifiziert ihn mit den Worten: “Matschke kennt das Sicherheitsgeschäft seit Langem: Er war 1972 bei den Olympischen Spielen in München selbst mit Sicherheitsaufgaben betraut und beschäftigt unter anderem ehemalige Mitarbeiter des Bundeskriminalamtes, des Verfassungschutzes und des Bundesnachrichtendienstes. “

Klingt alles schwer beeindruckend, hat nur leider rein garnichts mit Kompetenz beim Thema Geokoordinaten und Raketen zu tun.

Die Annahme, daß eine Gruppe fieser Böser ™ sich wirklich eine Rakete (oder von mir aus auch einen Marschflugkörper) bauen oder beschaffen könnte, der 300km weit fliegt und dann Stadion von ca. 300x500m Durchmesser trifft ist schon reichlich weit hergeholt (zumindest für die nächsten paar Jahre), wenn auch nicht gänzlich undenkbar. Nehmen wir dieses Szenario vorrübergehend als gegeben an, damit wir uns in Ruhe der Kernfrage des Artikels widmen können: der Beschaffung der Zielkoordinaten via Google Earth.

Angeblich sei die neue Gefahr, daß man in Google Earth die Koordinaten von Gebäuden auf die Bogensekunde genau erfahren kann. Oh Schreck! Damit liesse sich ja die Rakete zielgenau steuern! Tja.

Nehmen wir das Berliner Olympiastadion als Beispiel.
Die Wikipedia hat die Koordinaten wirklich genau. Der Berliner Stadtplan auch. Selbst die sonst etwas schnarchigen Berliner Behörden haben hochpräzises und geokodiertes Kartenmaterial zu bieten. Besonders lustig sind die Geocacher, die haben einen Wettbewerb bei der sie Geocaches in alle WM2006-Stadien verstecken. Ob das alles Fiese Böslinge ™ sind die das alles nur als Tarnung machen? Wohl kaum.

Ein weiteres Detailproblem an der Behauptung ist, daß die Genauigkeit der Koordination von Satellitenbildern in Google Earth nicht immer so genau ist wie allgemein angenommen. Durch so lästige Details wie die Entzerrung und Projektion der Bilder und die Umrechnung in und aus verschiedenen Koordinatensystemen sind in der Realität diverse Abweichungen in alle Richtungen zu verzeichnen. Ein auch nur halbwegs klar denkender Terrorist würde also eher die amtlichen Katsterkarten zu Rate ziehen oder einfach jemand mit einem GPS ans Ziel schicken, um die Koordinaten aufzuzeichnen. Dazu muss der Übeltäter nicht mal direkt dem Ziel aufs Dach steigen, es reicht in der Nähe zu sein und mit einem Laser-Entfernungsmesser das Ziel anzuvisieren. Aus Kompassrichtung, Entfernung und der eignen Position (GPS-Empfänger) wird dann die eigentliche Zielkoordinate berechnet. So machen das die Militärs auch, wenn sie Ziele für Bombardierungen bestimmen und dabei ein bischen Sicherheitsabstand halten wollen. Manchmal geht das auch schief, z.B. wenn die Batterie des GPS-Gerätes ausfällt und danach der Offset zum Ziel weg ist. Dann wird die Koordinate des GPS-Gerätes und nicht die des Ziels übermittelt (nach GPS im Artikel suchen).

Herr Matschke hat also ganz offensichtlich die letzten 10 Jahre Technologieentwicklung verpasst oder ignoriert und Herr Boeing war so beeindruckt von den ganzen tollen Geheimdienst-Hechten, die Herr Matschke beschäftigt, daß er das Nachrecherchieren vergessen hat. Nunja. Kann ja mal passieren.

Wozu man allerdings metergenaue Koordinaten für einen Terroranschlag mit Boden-Boden-Rakete benötigt wird nicht so ganz klar. Die im Artikel erwähnte “SS-185” gibt es schlicht nicht (selbst das Typenbezeichnungen aus Quellen kopieren ist offenbar schwer…). Auch zu dem in der Referenz zitierten Typ S-185 finden sich keine Daten.

Nehmen wir also – mangels eines genauen Typenbezeichnung – anhand der angeführten Kerndaten an, es handele sich um eine Kurzstreckenrakete russischer Konstruktion, mit mindestens 300km Reichweite. Gewöhnlich haben Raketen mit 300km Reichweite einen Sprengkopf von ca. 1000kg. Da kommt es auf 20 Meter rechts oder links nicht wirklich an, wenn man von einem vollbesetzten Stadion als Ziel und einem Splittersprengkopf ausgeht. Die Genauigkeit der üblichen russischen Boden-Boden Raketen ist auch eher im Bereich von 50-100m (bis 1,5km bei den älteren Modellen), da nutzen metergenaue Koordinaten nicht so schrecklich viel.

Wo genaue Koordinaten hingegen schon etwas nutzen, sind langsam fliegende GPS-gesteuerte Flugobjekte. Schon seit diversen Jahren gibt es mit fortgeschrittener Modellbautechnik gebaute Geräte die auch schon mal alleine über den Atlantik fliegen können. Auch Iran hat derartige Technologie schon am Start und offenbar auch mal an die Hizbollah für einen kleinen Rundflug über Israel verborgt. Ob ein AWACS genügend Radarauflösung hat, um so ein Ding zu erfassen, entzieht sich meiner Kenntnis. Die letzten Update-Programme für die AWACS zielten genau darauf, die Erfassung von Zielen mit kleiner Radar Cross Section zu verbessern.

Wir halten also zusammenfassend fest:
– Herr Matschke geht besser wieder Produktpiraten jagen
– Herr Boeing muss besser recherchieren
– Technology Review muss mal wieder klarkommen
– Genaue Geokoordinaten gibt es an jeder Ecke
– Google Earth ist toll und sollte endlich ein schnelleres Update der Sat-Bilder hinbekommen
– Modellflugzeuge mit GPS sind ein tolles Hobby, daß leider Gefahr läuft in Verruf zu geraten
