Critical error on Couchapp push with Ubuntu

I am hoping that in posting this, someone is able to save a little time and frustration.

On my Ubuntu 10.10 machine with CouchDB 1.0.1 installed, I began experiencing the following error every time I attempted to ‘couchapp push’ my couchapp changes:

[CRITICAL] Expecting object: line 2 column 3 (char 4)

After a bit of noggin scratching (and perhaps a little mumbled cussing), I started thinking about the fact I had not upgraded my couchapp install since long before I last upgraded CouchDb.

Running the following cleared up all error and put me back in the happy land of  ‘couchapp push’:

“easy_install -U couchapp”

Yup… Just a version issue…  Hope this saves someone a few gray hairs…

GRUB2 – Link worth mentioning

After countless wasted hours, I feel this link is one worth making note of : Grub2 Ubuntu Community Documentation.  The defacto since 9.10, things are a bit different from how things were handled in ‘just Grub’.  After years of learning the ins, outs and peculiarities of Grub, having readily available access to docs on Grub2 is a necessity when tacking installs of the latest and *cough*used loosely*cough* “greatest” distro releases.  After tacking with a mismanaged auto install of Ubuntu 10.04 (Lucid Lynx) on my P5n-e SLI based desktop (Raid, SATA+IDE, SLI and the works), I just thing that this link merits special mention…

It was likely some 100 threads before clicking through to this very link, so here it is – preserved for your and my reference!

Free Knowledge… Free as in Beer… Welcome Academic Earth!

Academic Earth

Academic Earth

I recently stumbled upon this article and was shown the marvel that is Academic Earth.  Academic Earth is a beta service that specializes in providing entire courses of high quality academic video lectures for free via their website.

The site’s main page shows the lectures to have come from the likes of Berkley, Harvard, MIT, Princeton, Stanford and Yale.  Just a quick stroll shows weeks worth of what appears to be pretty valuable content.  Topics include Astronomy, Biology, Chemistry, Computer Science, Economics, Engineering, English, Entrepreneurship, History, Law, Mathematics, Medicine, Philosophy, Physics, Political Science, Psychology and Religion – many of which contain entire courses worth of material… for free… Free as in beer.

Of course, I am really excited about the Computer Science section – there seems to be a solid line up of topics ranging from introductory to incredibly advanced.  Of course, this is not the first venture into freely available online educational resources (My favorite, for example – OpenCourseWare from MIT), but those visual learners out there (Ew, ew, ew!!! Me, me, me!!!), this is a god-sent!
