Is Life and Work Like a Big Game of Chess?

Saturday, July 13th, 2013

Chess is fascinating. I always tell people it reminds me of real life in the way of developing a strategy, reading your competition and thinking several steps ahead of them, and of course battling it out for that final checkmate. Chess is believed to have originated around 600 AD in what is now Afghanistan or India and indeed was much based on warfare where what we today call the pawn, knight, bishop, and rook represented the four divisions of the military: infantry, cavalry, elephantry, and chariotry.

Configuring a Syslog Server on CentOS 6.3 for Dell Force10 Switches

Thursday, July 11th, 2013

In this lab I’m going to demonstrate how to configure a syslog server to use with Dell Force10 switches. A syslog server can be used to store log files remotely on an external server. Syslog servers can be invaluable when troubleshooting. If a switch ever fails or reboots, no worries your logs are still available via the syslog server, and you can now analyse them to troubleshoot. An engineer can have multiple network devices write to one syslog file, or, if desired, a seperate syslog file can be created and stored remotely for each network device. (more…)

Investing Into Entrepreneurs More than Ideas/Products?

Thursday, July 4th, 2013

StartupI’ve seen it many, many times where investor(s) invest into an idea because they have some belief in the idea/product but more belief in the entrepreneur(s) behind it. This isn’t to say that investors/angels just throw money down on worthless ideas/products simply because of the person behind it. Rather, it’s the person/entrepreneur behind the pitch that can make or break a deal. Obviously, numbers are very important: market size, sales, profits, debt, customer base, etc. However, many times, a venture can be very early in its lifecycle or the numbers can be good but assurance is needed in the individual calling the shots and steering the ship on its course to expansion and financial success.

Cisco Nexus 5548UP – Configuring the Management Interface

Wednesday, July 3rd, 2013

This is a relatively simple blog on configuring the Cisco Nexus 5548UP management interface. When Cisco moved away from IOS to NX-OS for the operating system on their new Nexus datacenter switches, some of the commands and syntax for even the simplest tasks have changed. For easy reference for a common task such as setting the management interface I decided to write this quick blog. The network diagram is below. I am using a Dell S4810 [FTOS 9.1] for my management switch to which both the Dell PowerEdge R710 server and Cisco Nexus 5548UP [NX-OS 5.2(1)N1(1b)] connect. I also use a 1000Base-T SFP transceiver to convert the Dell S4810 fiber port to copper, so I can connect it to the management port of the Cisco Nexus. (more…)

The Moons of Mars – Phobos and Deimos

Phobos and Deimos orbiting Mars

Phobos and Deimos orbiting Mars

Phobos and Deimos, are the two small moons which orbit Mars. Their origin still remains unclear, but Asteroid capture is the most accepted theory. Interestingly, from the surface of Mars, Phobos rises in the west and sets in the east; it then rises again in just 11 hours. Deimos, happens to be just outside the synchronous orbit (where the orbital period would match the planet’s period of rotation); in consequence, although it rises as expected in the east, it does so very slowly. Deimos has a 30 hour orbit or 2.7 days elapse between its rise and set for an equatorial observer. (more…)
