This blog is a space for my thoughts, ideas, concept development, observed oddities exploration but mainly for much needed RANTING space from a frustrated penguin against the powers that be. Long live the yellow beak!

SchemaSpy – Automatic ERD
SchemaSpy is one of these tools that most sysadmins seldom use, it is mostly used by developers or DB admins. A quote from the site will explain the goal of this tool clearly: “Do you hate starting on a new project and having to try to figure out someone else’s idea of a database? “. [...]
AWS reserved instances – when is it cheaper?
Few months ago AWS published a new reserved instances proposition. While there’s a lot of data on their web site it escapes me why would they leave out an important piece of information: When do the reserved instance deals become cheaper than standard allocation? Below is a graph for the yearly costs of all instance types, [...]
Vi by example – Buffers
Notes:
1. Open files in Vi are stored in buffers.
2. Unless the buffer is explicitly deleted (:bdelete, :bwipeout), or Vi is exited, the buffer will remain in memory and available.
Example:
1. Start editing file1.txt – # vi file1.txt
2. Edit file2.txt in a new window – :e file2.txt
3. Get all available buffers file names – :b <ctrl-d>
4. Go [...]
IAAS CPU bursts – Can it be bad?
Rackspace, in its cloud servers service, generously gives hosted machines unallocated CPU cycles, above the guaranteed levels (reference). In a study I’m conducting these days, comparing performance of the biggest IAAS providers, this innocent feature revealed itself very clearly. Comparing the smallest instances of both EC2 and Rackspace CPU benchmarks, and normalizing to benchmark points [...]
Venetian Snares, suprising beauty
A truly beautiful piece by Venetian Snares. Not for the aggressive D&B or Underground intolerant.
Anti-human Computer Interafces
Spending many of my days in front of computer interfaces makes me wonder how things has sunken so low. The whole concept is wrong. Computer interfaces are just too damn far from what they should and can be. I’m including here just about every possible interface I encounter. It’s true that some of the programs [...]
IAAS Providers – Feature Comparison Chart
A simple feature chart of Amazon EC2, GoGrid and Rackspace virtual servers (A, G and R in the chart, respectively). The BogoScore at the end is just the count of supported features, it doesn’t mean much but I just had to do it. Black squares are supported, white are not and grey are partly supported.
