Internets of Interest for 26th November 2012

 

Collection of useful, relevant or just fun places on the Internets for 26th November 2012 and a bit commentary about what I’ve found interesting about them:

40 Gigabit Ethernet on Cisco Catalyst 6500 Series Switches: How It Works  [Cisco Catalyst 6500 Series Switches] – Cisco Systems – If you are Cisco 6500 lover, you will need to keep up with “new” technology (hah, the word ‘new’ in a 10 year old product).

Also, Cisco continues to lead the way in exposing technical data about their products – at least I know about the limitations of the module and I can provide higher level of assurance to ‘the business’.

This white paper explains the high-level architecture and packet flow details of the 6904 line card in the Cisco® Catalyst® 6500 Series Switch. The paper assumes knowledge of the basic concepts of Policy Feature Card 4 (PFC4) and associated terminology detailed in the white paper Cisco Catalyst 6500 Supervisor 2T Architecture.


Fabric: A Retrospective on Evolving SDN – White paper from the Nicira people about replacing MPLS with SDN. Consider the lily gilded.

MPLS was an attempt to simplify network hardware while improving the flexibility of network control. Software-Defined Networking (SDN) was designed to make further progress along both of these dimensions. While a significant step forward in some respects, it was a step backwards in others. In this paper we discuss SDN’s shortcomings and propose how they can be overcome by adopting the insight underlying MPLS. We believe this hybrid approach will enable an era of simple hardware and flexible control.


Cisco Nexus 7000 Series NX-OS Release Notes, Release 6.1  [Cisco Nexus 7000 Series Switches] – Cisco Systems – Latest Nexus 7000 NXOS release supports Python scripting.

Python scripting provides programmatic access to Cisco NX-OS and allows you to gather network intelligence. Python is a very powerful programming language that includes standard libraries and it is highly scalable. Python is integrated with PoAP.

That’s SDN, but is it SDN that people want to use.


Microsoft’s Big Hidden Windows 8 Feature: Built-In Advertising – HotHardware – Ads are bad in commercial software. Really bad. But mostly I’m concerned about the tracking – how much information is Microsoft stealing and analysing to profile you and your private activities. Of course it’s all in the name of “ads you want to see”. In Enterprise Security, this would likely be regarded as data theft through target profiling.

The answer of just how wrong Microsoft is to cram advertisements in its commercial software will differ from person to person, I’m sure. Me, I’m not too bothered, but I can totally relate to anyone who is. From all I can tell, none of the ads are intrusive, and I appreciate that. As for them being in paid software, that doesn’t bother me either because of that above fact. However, I am bothered by other aspects.


Why I Did Not Hire You – An Open Letter to a Failed Job Applicant – I think someone had a bad candidate in a job interview because this sounds like a candidate from the dumpster

Questions–I have to admire the way you showed absolutely no interest in my company… none, nada, zip. It takes a remarkable amount of focus and dedication to remain that entirely disinterested in a company you, ostensibly, are interested in working for. I have a hard time hitting that level of indifference on topics as mundane as toilet paper color, so that’s something. For future interviews, however, you may want to come armed with some basic questions that show you are at least aware of the company name. Start slow, then work up to more detailed questions like:

(1) What kind of company is this?
(2) What do you make? Or sell? Or do?
(3) Will I be paid?
(4) Am I expected to wear clothes?


Mac Gems: FoldingText is a unique and versatile text editor | Macworld – Folding Text is my current text editor. Not only can I use Markdown formatted text, I can also collapse text areas, make todo list within a docouments, set timers for writing bursts.

And the developer has plans to do a lot more. While Folding Text isn’t Sublime Text or BBEdit, it’s a hard core writing tool for me. ( I still use MultiMarkdown Composer for some tasks, more of this later.).


5 most surprising things heard at Harvard’s Cyberposium — Tech News and Analysis – I found a few things in this article that resonated with me:

5: Enterprise social tools are great if the culture is right.

Social tools don’t work for most enterprises. Few people care enough about their employer to enable a social mindset.

2: It’s not just the software, stupid.

People are besotted by the latest and greatest software. But — as we’re starting to learn from the tablet revolution — designing hardware to properly surface all that cool software goodness is critical. And making hardware and the interface to that software that is drop-dead simple is tough.

I agree – the rush to software for faster innovation is ignoring the value of hardware. Software is uterly dependent on hardware and will always be so. Some hardware is ahead of software & when the equilibrium returns……

That being the case, the question is: “What is the value of an MBA?” They were probably not comforted by Cloudant’s Sam Bisbee when his big data panel was asked about how MBAs can get into that burgeoning field.

His answer: “Don’t be an MBA … You need a technical background.”
