Freelance - the term for a Knight of honour that is not pledged to a Lord. Modern Use: person who pursues a profession without a long-term commitment to an employer
On the contest field, each Knight would pledge his lance to the Lord who owns his fealty. A Knight with no such pledge was Free Lance. Free as in freedom to choose his contest and the nature of the fight.

Network Dictionary - Velvet Rut
September 26, 2008 by Greg Ferro · Leave a Comment
“velvet rut” describes operational practice in a network that hasn’t changed in along time. Typically, some action that is done that way “because it’s always done that way”. Because it works and the world is a happy place therefore the practice must be a good one.
Being stuck in a rut is no excuse for not changing, but good practices can be worth keeping - and are described as ‘the velvet rut’.
Blessay:Cloud Computing Not “Essential Service”, More Like “Public Transport”
September 24, 2008 by Greg Ferro · Leave a Comment
Cloud Computing is generating a lot of smoke, but it is hard to find flammable material that makes it “hot”. Cloud Computing is unlikely to become Essential Service, but will be more like Public Transport - cheap, mass capability, limited function and “acceptable” for some. Read more
Network Dictionary - Tuple

Tuple
1. English term that is used to refer to a “number set” of things. Thus quintuple and sextuple are examples representing a “five set” and “six set” respectively..
2. Used generically to describe a IP connection data set, thus, IP/Mask/Next Hop is known as the routing tuple, Source IP / Source Port / Destination IP / Destination Port is referred to as an IP Flow tuple, and
The IP routing tuple is network / subnet / next hop.
A host IP tuple is IP / mask / gateway (although some would corrupt the purity of IP with DNS entries in the data set.
I use this often in thinking over design and in documentation as it saves lot of typing.

Network Dictionary - Orgy of Failure
September 15, 2008 by Greg Ferro · Leave a Comment
“orgy of failure” is the party thrown at the end of large project to celebrate it’s “completion”.
This is not necessarily a negative term, but usually, it is.
At some point in your career you will be involved in a project that doesn’t achieve the original goals, but will be declared a success by ‘adapting the goals’ or ‘realigning to business requirements’. This completion party is usually more fervent and desperate in this case because everyone is so relieved it’s over.
We gather round, and drink heartily, laugh nervously, eat with gusto in an “orgy of failure”.

Therefore a Network Designer needs to ensure that they are overriding their natural instinct. Read more

Rant:Managing Is Easy Compared to Technical Life
September 4, 2008 by Greg Ferro · 10 Comments
Not everyone will be a good manager, but very few people will ever be a good, I mean _really_ good, technician or engineer. You should be willing to pay for that.
