Internet security issue - change your passwords (heartbleed) - *UPDATE*

*UPDATE*

You  may be aware of this by now, but if not some info about heartbleed. It does impact dropbox, yahoo (and all of its services), soundcloud and many, many other sites. Google was vulnerable but fixed it as others (including Facebook) have.  It does not seem that the banking sites were hit (yet), but it might be a good time to change all of your passwords.

This is a short list – a longer list is at github.

Making it happen - linkeddata, bigdata, opendata and the semantic web

So, a question was asked in one of my linkeddata discussion groups. How does linkeddata, bigdata, opendata and the semantic web fit together?

My answer:
The Semantic web is the interface to make sense of all of the data (bigdata) which has to be accessible (open data); linkeddata is the mechanism making the data connections which are interpreted by the semantic web.

A very simplified view, for sure but I think it sums it up in a sentence.
