Collection of useful, relevant or just fun places on the Internets for 1st June 2012 and a bit commentary about what I’ve found interesting about them:
Network Ninja Routing Terminology: How To Sound Like You Know What You’re Talking About – I can go with this:
To wrap things up, my security guy doesn’t sound like he knows what he’s talking about for several reasons:
Classful routing died in 1993.
172.16.9.0/24 is not even in Class C, see the definition above.
His concern over the firewall rule is related to the size of the network involved, yet he’s complaining about the first bits of its address.
Experiences of deploying the first Juniper Network… – J-Net Community – blah blah, (be nice to vendor) blah blah (make pleasing sounds) blah blah (corporate dullness) – it worked after lot of hard work. Result.

“They’ve broadened my eyes about SDN and without them; I think a lot less people would know about or care about SDN. Keep up the good work, guys!”
I think that Dan Pitt and Talayco are far more deserving than us but it’s nice to be recognised.
Sales of unused IPv4 addresses gathering steam – IPv4 addresses can be used to fund an IPv6 migration if you are lucky. Although, it feels pretty exploitative to sell of something that you were given for free to make a better society by having freedom in communication.
Lindsey says the most common unit of IPv4 addresses for sale right now are /16s, such as the California woman has for sale. “The unit of measurement of value is a /16,” he says. “The range I’ve seen for a single /16 is anywhere from $8 to $13 per address.”
Ageing eyes hinder biometric scans : Nature News & Comment – Security fail:
It is not clear why irises were assumed to be somehow immune to the ravages of time. According to Bhagavatula, it is partly because of a lack of long-term data. But Bowyer’s view is that it comes down to an incorrect and optimistic assumption made at the outset of iris biometrics. “This assumption was repeated often enough, and in a convincing enough manner until it became fact,” he says.
Sometimes you just want to believe that there is a magic solution to identity management. Iris scanning of the eye has “token sync” problems.
A story from a prior company. I was an engineering manager that had a retention problem. One of the engineers on my team quit to go to a smaller, hipper company. This was from my exit interview:
Me: why are you leaving?
Him: because they have bigger monitors.
Respect for your engineers comes in many forms – sometimes just giving them the best tools to achieve excellence is enough. Not giving them tools to be great is a crime.
When you run a large data center it is cheaper per unit to run a large thing rather than a small thing, unfortunately in networking that’s not really true. -Urs Hoezle, Google
But apparently I said this sometime or other:
OK, gotta pick my favorite and since Ferro wove in beer, cars and girls. His endorsement of the potential is about as good as anyones in the industry in my opinion.
Seeing it written down, that’s kind of funny. Check out the blog post, it’s great.
