Ubuntu, RedHat/ CentOS, Amazon, and Fedora have already released patched versions of the OpenSSL library. Upgrade now. Do it now, as in right now. If you've compiled your own version of OpenSSL from source, upgrade to 1.0.1g or rebuild your existing source with the -DOPENSSL_NO_HEARTBEATS flag.

Once that's been done, stop any certificate-using services, regenerate the private keys for any services that use SSL ( Apache, MySQL, whatever), and then obtain a new SSL certificate

…about Heartbleed before the distribution maintainers at e.g. Ubuntu and RedHat did. This kvetching is wrongheaded, because the logo designer only needed the instruction "We have a project named Heartbleed. Come up with a logo which says serious danger ." rather than "Apropos of nothing, mostly non-technical logo designer, the heartbeat protocol in OpenSSL 1.0.1a through 1.0.1f has been fubared for 2 years now. Don't tell the Ubuntu guys though, we're trying …

"We ran RedHat and there wasn't much out there for RedHat at the time, especially as the Community had just begun to come together. So I wrote some Cookbooks myself and open sourced them. The feedback was immediate. The IRC lit up! Everyone had similar challenges and different ideas - it led to a lot of awesome collaboration. I have contributed to over 50 community cookbooks, and roughly 20 of those are personally maintained."

Some of Eric's most notable contributions …

Keith Perhac and I are back with the 5th epsiode of the Kalzumeus podcast.

Keith and I both have experience working as consultants in software development and online marketing. People often ask us how to transition away from the feast-or-famine nature of freelancing, where you do very well when you're delivering engagements and getting them paid quickly, and then do very poorly when work dries up or you have invoice collection issues. One way to improve on this is building recurring …

…that repo, but you should get the idea and should be able to modify the script to build on vanilla Redhat linux w/o additional packages). Another option would be to take a look at Cloudera's GPL Extras repository and their lzo packages and documentation .

After you have built and installed your LZO libraries, you should be able to use them with HBase without any additional configuration. To test HBase support for LZO compression you could use the following …

In case there is documentation I compare the experience to RPM ( Redhat Package Manager):

I need to learn about X

But have to read about Y first.

To understand Y I need to dive into Z.

Sounds familiar? Dependency resolution in documentation. However, of course there's always also light at the end of the tunnel โ€” it's when it all works โ€” I conquered a problem and defeated the proxies and caches. ;-)

Entities

Entities can be incredibly simple โ€” take the persistent object: …

It was two days after RedHat had released OpenShift, so I had a few bonus comments to make about OpenShift towards the end of the talk. I'm also some what liberal with making jokes about any other technology that comes into my mind at the time. A politically correct person might have said different things.

At the time of the talk, I was not able to give a live demo of BOSH. I think such a demo would be valuable to get a complete "what is BOSH?" understanding, since it was …
