Collection of useful, relevant or just fun places on the Internets for 12 December 2014 and a bit commentary about what I’ve found interesting about them:
Practical demonstration of the differences between Docker & Vagrant
After the post was published, Twitter user Mark Snow (@highspeedsnow) wondered whether I’d tried Vagrant. Vagrant has been on my “must get round to trying” list, so despite the fact that pretty much any solution will be “too much solution” for the specific use case I had in mind, it seems churlish not to try out another solution that I can, in time, most likely reject as pointless.
A great free font from the League suitable for headlines, titles and front pages of documents.
A new classic, this is a bold, modern, geometric sans-serif that has no problem kicking its enemies in the chest.
Definitely one to have in your toolbox.
Because there is always something to look up this official Wikipedia App for the iPhone will replace a couple of other apps
Official Wikipedia App for iOS. Wikipedia is the free encyclopedia containing more than 32 million articles in 280 languages, and is the most comprehensive and widely used reference work humans have ever compiled. The app has been rewritten from scratch and is better than ever before.
You can’t beat Wikipedia for basic reference information, especially on networking technolgies that aren’t in the core of my expertise.
Ethan Banks is talking about the constant stream of requests we get from companies who expect, or even demand, that we promote their product on our websites.
Packet Pushers won’t engage in these sorts of marketing tactics. Why? We have an implicit agreement with our audience to be honest with them about what they are getting. Sponsored content is clearly marked as such, and always will be. What’s more, Packet Pushers won’t allow just any old content to hit our feeds just because someone is willing to throw a few dollars at us. We screen companies. Every sponsored podcast is based on an outline we helped put together, trying to make sure it’s going to be interesting to the audience. Every sponsored blog post hits our eyes before it hits the feed. We make recommendations about how to improve vendor content so that a reader will get a benefit from it.
What makes this offensive is that these people don’t respect or even comprehend the time and commitment is takes to blog, podcast or write consistently. Its not wrong for them to make money being in marketing, its not wrong for their targets to get paid as well.
Alcatel Lucent announced their software router this week. Unlike companies like Cisco and Juniper, they make it plain that SDN/NFV is big deal
It is not an understatement to say SDN and NFV are a seismic shift in the way service providers think about their networks. Indeed, SDN and the virtualization of network functions will be seen as one of the industry’s defining moments – it will change the way our customers design and build their networks, and the way they offer services.
I took a look at their VSR and it’s shipping today with 160Gbps of performance out of the box. Wonder what the licensing costs ? Is it prohibitive like Cisco & Juniper ?
The Internet Architecture Board is stating that new protocols should have encryption enabled by default.
Newly designed protocols should prefer encryption to cleartext operation. There may be exceptions to this default, but it is important to recognize that protocols do not operate in isolation. Information leaked by one protocol can be made part of a more substantial body of information by cross-correlation of traffic observation. There are protocols which may as a result require encryption on the Internet even when it would not be a requirement for that protocol operating in isolation.
The impact on network security over time is enormous. There are lobby groups ( like the so-called Open Web Alliance ) that oppose encryption because it reduces the effectivenes of load balancers, NAT gateways, Fancy QoS and more.
Terminal / Monospaced Font that I will be using for a while.
I went through the current Menlo drop from Apple, and re-created the same changes I had made to create Mensch. With so much more control over the shapes, it came out a lot better. It might not be obvious on a non-retina screen at a small point size, but it’s a pretty clear improvement on the new screens. I’m still calling it Mensch, but it’s a Mensch 2.0.
I like Menlo but not enough to use it. Maybe this will be a better version.
