LogStash / CouchDB / ElasticSearch -> Bending your rivers

ElasticSearch used to have a nice feature called “rivers”. Using a river it was easy to get your CouchDB data into an ElasticSearch index. Since ElasticSearch 1.5 rivers are deprecated.

Why I am FedUp with Fedora 18 (Pun intended)

Hi again,

Just today I have upgraded my Fedora 9 IPA-server to the latest Fedora version, namely Fedora 10.

As reckless can one be.. just upgrade the system (with all of its db4 libraries), while the ipa instance is still running, increasing the risk of corrupting the (live) berkeley databases that are the back-end of the ldap instances.

Keyboard problems in GNOME

I can’t understand why, but as a Dvorak typist I run into problems with GNOME. GNOME has a nice feature to switch the keyboard lay-out from the default, QWERTY, to the Dvorak layout.

But, it doesn’t (reliably) work for Ctrl and Alt keys. I am not sure what causes the troubles, but according to . . . → Read More: Keyboard problems in GNOME
