Secunia PSI Fail

Actually, I like Secunia’s PSI: it makes keeping a Windows PC up-to-date a lot easier.

But today it failed:

  • Update of flashplayer did not work, but showed this:

    Notice how it says in green 100%, but Firefox and IE were still using the vulnerable version.

    Maybe it got confused by Chrome’s autoupdate which ran in parallel.

    A re-scan make PSI aware of the problem, but the autoup-date failed again.

  • It failed to update irfanview
  • I spent a few mins looking for an email address for feedback and found none. Thus this public blogpost.

I’ve too many Tabs open in Firefox. But instead of bookmarking them (where they will rot forever) I’ll post them here to compost in the blogsphere so that they might provide nutrition to others.

DNSSEC Troubles

I’ve given my share of DNSSEC talks over the last three years. I usually explain what exactly DNSSEC provides and what it does not. One of the downsides I tell ISPs about is that other people’s DNSSEC errors will hit your call-center if you’re doing DNSSEC-validation.

This just happened to Comcast.

I really recommend that anyone enabling DNSSEC validation on their resolvers should be prepared for this case. The report from Comcast is instructive, especially the media fallout they had to cope with.

Textbooks on the iPad

Apple announced last week that it wants to change the way textbooks work for US schools: Instead of schools buying books that are given to a succession of pupils, each kid should receive its own copy of the textbook as an ebook on his iPad.

So far, so interesting. I have two observations on this:

a) Richard Stallman wrote once a short story called “The right to read“. Having textbooks solely on DRM-infected ebook readers is yet another step in that direction.

b) This is a huge opportunities for crowd-sourced textbooks. The material that basic textbooks cover have been summarized, prepared for lectures, lessons, books, … by successions of teachers, home-schoolers, students and other people over and over again. This is a market that is pitch-perfect for some sort of Wikipedia-style cooperative editing.

There will be no single common edition for all topics, some are just too controversial. In other cases, there will be different approaches on how to teach a certain subject. Nevertheless, if it is easy enough to share enhancements to copylefted textbooks, we might see that many teachers will enhance the ebook for their class (add some multimedia content, add exercises, provide additional information) and feed all these back into the public pool of ebooks.

Optimally, this would work as a plugin into Apple’s ebook writing software to make it a seamless experience. The economic incentive for Apple is not there, so I doubt that will happen soon. But if someone writes a decent conversion tool that takes a set of pages from Wikipedia (perhaps enhanced with some special tags for this purpose) and builds a textbook from them, this could take off very quickly.

This could do to textbooks what Wikipedia already did to lexica.

(And of course, Amazon will also try to ruin Apple’s plans.)

The WOW-Effect

This week I had some fun helping a co-working with a paper regarding the effect of WOW64 (the 32-bit environment of 64-bit Windows) on various tools and procedures that security analysts use.

The result is here: The WOW-Effect.

We did away with the old children’s corner in the living room and the new setup gives us more space. See e.g. these tracks:

#DigiNotar and paying for an audit

The question Mozilla, Microsoft and Apple should be asking themselves now is:

Which other CA do they trust based on an audit by PwC? Their green light on DigiNotar was so flawed that I have serious doubts about anyone else they certified as a trustworthy CA.

This is a bit like the financial rating agencies at the height of the 2008 banking crisis: why the hell should I trust the audit/rating of someone who is paid by the people they are auditing/rating and who need an “all fine”/AAA result?

RIP Semantic Web

How many research grants have been awarded to “Semantic Web” research proposals over the last few years? I always maintained that this is a typical academic solution to a problem that will be solved by very simple additions to the existing web like microformats.

Now the search heavyweights have joined the semantic web for real. But not by doing RDF or any of those full blown perfect solutions developed over the last years by burning research money.

As I see it, most of the research projects are now completely obsolete given the launch of schema.org.
