1. Snowflake Networks – Lost In Transit

Daniel Dib examines some common reasons why complexity creeps into network design and operations, resulting in the fabled “snowflake” network. Those reasons include inexperienced networkers, lack of a proper design process, and business requirements. He also offers tips for dealing with complex networks, since we all know they aren’t going away.

2. netdev day 1: IPsec! – Julia Evans

Julia Evans is a software developer who’s actively learning other parts of the IT stack, including networking. She shares her learning through blog posts and illustrated zines, which is pretty cool.

4. Independence, Impartiality, and Perspective – Networking Nerd

When reading technical blogs and content, it’s normal to want to know if the author is independent or impartial–that is, are you getting information or a viewpoint that isn’t swayed by some commercial influence or interest. Tom Hollingsworth, who helps run Tech Field Day and relies on the tech community for delegates, parses the differences of being independent and impartial.

Tech News

 1. Amazon’s cloud unit plans to sell own networking switches – The Information – Reuters

Tech website The Information cites unnamed sources saying the Web giant is mulling whether to sell whitebox switches directly to its customers to better integrate its cloud services with customer data centers. Stock prices of incumbent switch vendors dipped a bit, but it’s not clear if Amazon is just floating an idea to gauge the reaction, or if it really plans to get into the network hardware business. I need to think about this one a bit longer.

The link below is a summary by Reuters. The Information’s site is gated, but if you are willing to give them your email, you can read the original here.

4. How Silicon Valley Fuels an Informal Caste System – Wired

A former startup founder and Facebook employee ruminates on the 4 class levels emerging in San Francisco and Silicon Valley: the Inner Party (VCs and rich entreprenuers), the Outer Party (coders, engineers, technicians), the Service Class (Uber drivers, restaurant workers), and the Untouchables (the poor, the homeless).

“The Service Class will likely never be able to drive/shop/handyman enough to rise to the Outer Party, at least not without additional training or skills. They’re mostly avoiding the descent to Untouchable status, while dealing with precarious gigs that disappear semi-regularly.”
