Germany #VDS : constitutional violation for total surveillance
·
A new bill is under way in Germany that violates the constitution and paves the way to total surveillance.

Here's the statement from the free wireless for the public good community that'll be destroyed once the bill becomes effective:

Noch vor ein paar Monaten verkündete Vize-Kanzler und Bundeswirtschaftsminister Gabriel (SPD) bei der Veröffentlichung einer Neuregelung des Telemediengesetzes (TMG) einen "Schub für kostenloses WLAN". Bei genauerer Betrachtung des Entwurfs stellte sich schnell heraus, dass die Konsequenzen eines solchen Gesetzes zum Gegenteil führen würden: Noch mehr Rechtsunsicherheit und definitiv kein Schu ...

Du kannst doch weiterhin frei funken. Wir wollen nur, dass keine Dummheiten gemacht werden, die dem Grundgesetz widersprechen. So, nun hübsch brav sein. Gegen Paranoia bringt der Pfleger gleich was.

Why do they use the same name?
Staats... is similar to National
Sicherheits.... is similar to Security
Dienst is similar to Agency

So the difference is just the language. (And of course the efficiency) - but not the intention.

Uploads of #FOSDEM 2015 Videos
·
Yay! It looks like the FOSDEM videos are finally being processed and uploaded. I couldn't attend Brussels this year, so I'm eagerly waiting for Pippin's talk to come up. The desktop devroom isn't up yet, but at least the main track and some of the other devrooms are already (ca 25% at the moment).

key rotation in openssh 6.8+ http://goo.gl/QT34sE
Something that's bugged me about the SSH protocol is its lack of key continuity - key algorithm changes and key rotations are basically unsupported, as there is no in-protocol way for a client to learn updated host keys for h...

Thread Local Storage Benchmark - is #TLS even usable in practice?

A good while ago at a conference, I got into a debate over the usefulness of TLS (thread-local storage of variables) in performance critical code. Allegedly TLS should be too slow for practical uses, especially for shared libraries...

TLS is way useful if when allocation contention starts hitting your critical path.

Rapicorn #Devlog: shared_ptr, resources, eval syntax, etc
·
Giving in to persistent nagging from Stephen and Stefan about progress updates, I’m cherry picking some of the branches recently merged into #Rapicorn devel for this post. We’ll see if I can keep posting updates more regularly in the future…

Topics covered:
- Interactive Examples
- Shared_ptr widgets
- Resources
- New eval syntax
- What’s next

Avoiding the #FREAK #ssl Attack - #CVE-2015-0204
·
Apparently lots (+36%?) of HTTPS servers out there allow degrading of encrypted connections to weak 90ties-era cyphers; Matthew Green calls it the "Attack of the Week": http://blog.cryptographyengineering.com/2015/03/attack-of-week-freak-or-factoring-nsa.html

Here's what you can use to check you preferred HTTPS site for the weakness:
  openssl s_client -connect testbit.eu:443 -cipher EXPORT

You should be seeing a "*handshake failure*" for secure sites. If not, here's a previous blog entry that provides a secure Apache config disallowing weak cyphers altogether:
  https://testbit.eu/apache-sslciphersuite-without-poodle/ #security
Apache cipher setup (SSLCipherSuite) to enable HTTPS connections with perfect forward secrecy while avoiding the CRIME, BREACH, POODLE and RC4 attacks.

Beyond Open Source?
·
As a Free Software developer, I came across a very thought provoking piece by Drew Crawford today. I don't necessarily share all his views in detail, but I think he poses an interesting question. I'll summarize as follows:

TL;DR: Can automatic micro-payments redeem free & open software from the corporate strangleholds?

It's a long article but well worth it for developers: http://sealedabstract.com/rants/beyond-open-source/
I meet a lot of developers who have bought into the hype about open source. It's great! It's going to save the world from the perils of proprietary software! Or

What David Cameron just proposed would endanger every Briton and destroy the IT industry

Another great piece by Cory Doctorow, you don't want to miss it if you have the right to vote in the UK or know somebody with this right:

http://boingboing.net/2015/01/13/what-david-cameron-just-propos.html #cryptography #endtoend #election
David Cameron says there should be no "means of communication" which "we cannot read" -- and no doubt many in his party will agree with him, politically. But if they understood the technology, they would be shocked to their boots.
