Cloudflare has done a good analysis and fairly extensive testing on the #heartbleed bug and it seems as if the disclosure of the SSL private key is at least unlikely.

While in the process of evaluating data structures, especially for reducing the number of locks used, I found this presentation on a lock-free hash table by Cliff Click. Turns out, when explained like this, it is surprisingly intuitive.

With all these new SSDs doing encryption and Intel using the ATA password to secure the key, one would expect more people to be using it. But it is seriously hard to find 
a) reliable information if TPM modules are included on boards
b) maximum password length implemented in the BIOS (it is 32bytes in the ATA standard afaik)

Any ideas which boards support a password length greater 8?

I find the idea of "free" full disk encryption with absolutely no downsides seriously interesting and appealing.

Intel and Gigabyte have them at least in certain models. Usually need to have a TPM module somewhere. But there are nice hacks with added bios extensions via the network card ROM. :)

Great interview with +Larry Page 
 
A good example of why +Larry Page is the tech CEO I admire most.  From the recent Wired profile by +Steven Levy, entitled Why Moon Shots Matter:

"I worry that something has gone seriously wrong with the way we run companies. If you read the media coverage of our company, or of the technology industry in general, it’s always about the competition. The stories are written as if they are covering a sporting event. But it’s hard to find actual examples of really amazing things that happened solely due to competition. How exciting is it to come to work if the best you can do is trounce some other company that does roughly the same thing? That’s why most companies decay slowly over time. They tend to do approximately what they did before, with a few minor changes. It’s natural for people to want to work on things that they know aren’t going to fail. But incremental improvement is guaranteed to be obsolete over time. Especially in technology, where you know there’s going to be non-incremental change."

Very interesting talk by +Chandler Carruth about #clang, current features, error reporting, warnings, static & dynamic analysis and a few examples of possible error-conditions in c++11.

Really, so little anger in JS and PHP? ;)

Great talk about programming languages (in this case ruby and javascript) and their unexpected behaviors.
 
A fun video about some programming language "features" which make you ask "Wat?"

Awesome video about the research being conducted in the Mexican cave Ox Bel Ha by an international team of GUE divers and scientists.

Fantastic. I've dived the Cenotes many times over the years (Angelita is still one of my favourites because of it's uniquness) and it's always amazing to see how much of these systems there are yet to be fully discovered and mapped. Excellent documentary.

Just found this very good article by +Armin Ronacher  explaining #SQLAlchemy    with the   #django   ORM. While I didn't even know the latter, it still showed me some nice features and new things in SQLA.
