I’ve always found the tendency of Facebook users to over-share a little strange. You see people exposing their lives in ways that are occasionally charming, often inexplicable, and frequently downright ridiculous or ill-advised (or often both of the latter at the same time).
Probably shouldn't be posted on Facebook.
In the latter category are the posts of people who are obviously in advanced states of inebriation doing things that don’t require a caption to reveal that they are being idiots. These kind of posts are the sort of thing that, once sober, will be regretted and will never, ever disappear becoming fodder for the poster’s mother’s disapproval and unwanted attention from employers both current and future.

Since taking a new role at Cisco, my drive time is less consistent. As a result, finding opportunities to listen to podcasts is more of a challenge. Earlier this week, a road trip I took provided some time to start getting caught up on my listening. Using iCatcher allows me to easily tweet what I’m listening too. As a result of sharing what I listened to, I received some requests regarding the podcasts I listen to. I wanted to share this ever changing list with the PacketU community.
Also beyond the technology focus of this audience, I often listen to Cold Case Christianity–a Christian Apologetics podcast and Focus on the Family–a faith based podcast focused on strengthening families.
I’m always looking for new sources for good information. If you have podcasts that you enjoy listening to, please share them by sending them to @packetu or commenting below.

GigaOm published a great article on how NASA launches their web infrastructure into the cloud today. The article features our own Jonathan Davila.
To help with the nitty gritty details of transferring those applications to AWS and setting up new servers, NASA used the Ansible configuration-management tool, said Davila. When InfoZen came, the apps were stored in a co-located data center where they weren’t being managed well, he explained, and many server operating systems weren’t being updated, leaving them vulnerable to security threats.
Without the configuration-management tool, Davila said that it would “probably take us a few days to patch every server in the environment” using shell scripts. Now, the team can “can patch all Linux servers in, like, 15 minutes.”

Recently, I had to look after PBTS on Cisco ASR9K platform and faced some issues, here are some results about my tests. PBTS has the same goal as CBTS on Cisco IOS (Class-Based Tunnel selection) but for Cisco IOS-XR. It provides a tool to direct traffic into specific RSVP-TE tunnels (in the future Segment-Routing tunnels) […]
The post Policy-based Tunnel Selection (PBTS) on Cisco IOS-XR appeared first on Packet Pushers Podcast and was written by Youssef El Fathi.
This week, we announced new product starter kits that will make it easier for companies to adopt software-defined networking in a way that fits their unique networking environments. The kits are designed for three distinct uses — agile datacenters, distributed cloud environments and Big Data applications — avoiding the “one-size-fits-all” starter kit approach of some other vendors. Visit our product page to learn more. Below are our top picks for networking stories this week.
In this week’s PlexxiTube of the week, Dan Backman discusses the benefits of Plexxi’s Big Data fabric beyond Hadoop applications.
eWEEK: Plexxi Launches SDN Starter Kits for Cloud, Big Data
By Jeff Burt
Plexxi officials want to make it easier for organizations to adopt software-defined networking. Plexxi, a startup in the increasingly crowded software-defined networking (SDN) space, is unveiling three starter kits aimed at agile data centers, cloud environments and big data applications. Company officials said the goal of the starter kits is to give businesses and service providers the tools they need to deploy SDN infrastructures that are tailored to their particular workloads, avoiding what they said is a more one-size-fits-all approach that other vendors are taking.

While competing with Juniper will be interesting, we’re happy to see them recognize the customer drive towards Open Networking. Juniper indicates that they are joining the ranks of start-ups like Cumulus Networks and industry leaders such as Dell in this inevitable industry transition… avoiding the “head in the sand” perspective maintained by some other networking vendors.
There were four main sources of information as part of the announcement.
Initial reading shows us a focus very aligned with Open Networking. They say things like…
Juniper announced the OCX1100 that combines … Junos® operating system with Open Compute Project (OCP) enabled hardware
Let me say that again: Customers will have the ability to remove Junos and deploy another vendor’s operating system
To some not familiar with Juniper, news that we are embracing an open hardware design might sound counterintuitive in that anything “open” is not aligned with our strategy. On the contrary, Juniper has always embraced open architectures and open Continue reading
Our own Brian Coca presented at the recent OpenStack for Enterprises NYC Meetup and talked about how large companies are using Ansible and Ansible Tower.

A dozen webinars, tens of public presentations and on-site workshops, numerous highly interesting ExpertExpress sessions, three books and over 250 blog posts. That should be enough for a year; it’s time to go offline.
I hope your company has a New Year freeze (and not let’s upgrade everything over New Year policy), so you’ll be able to do the same and enjoy some time during the rest of the year with your loved ones. See you in 2015!
You might have noticed that blog content has been a bit sparse over the last few weeks. The reason I haven’t generated any new content is because all my spare time is taken up with preparing to migrate this site to a new hosting platform.
Sometime over the holiday season, I’ll be migrating this site from a hosted WordPress installation to Jekyll running on GitHub Pages. Given that I have 9 years of content (over 1,600 blog posts), this is a pretty fair amount of work.
Most of the “structural” work on the new site is already complete; you can get a preview of the site by visiting http://lowescott.github.io. There’s no content there yet (other than some boilerplate content), but you’ll be able to get a feel for how the new layout will look and work. As you can see, I’ll be using the Lanyon theme, which provides a nice clean layout and a good mobile as well as desktop experience.
There’s still some additional “structural” work to be done, such as adding support for comments (which will be handled via Disqus), but I hope to have that done in the next few days.

Vlad Krasnov recently joined CloudFlare to work on low level optimization of CloudFlare's servers. This is the first of a number of blog posts that will include code he's optimized and open sourced.
In a recent post, Kazuho's Weblog describes an improvement to PicoHTTPParser. This improvement utilizes the SSE4.2 instruction PCMPESTRI in order to find the delimiters in a HTTP request/response and parse them accordingly. This update, compared to the previous version of the code, is impressive.

PCMPESTRI is a versatile instruction that allows scanning of up to 16 bytes at once for occurrences of up to 16 distinct characters (bytes), or up to 8 ranges of characters (bytes). It can also be used for string and substring comparison. However, there are a few drawbacks: the instruction has a high latency of 11 cycles, and is limited to 16 bytes per instruction. It's also under utilized for range comparison in PicoHTTPParser, because it only tests two or three ranges per invocation (out of eight it is capable of). Furthermore, some simple math (16 bytes / 11 cycles) shows that using this instruction limits the parser to 1.45 bytes/cycle throughput.
As mentioned in an earlier post GNS3 is moving ahead fast. Currently at version 1.2.1 the GNS3 is looking great. Compared with the version 1.0 Beta 1 which I had installed, the 1.2.1 is not only more stable, but it has the Menu more clean and compact. For example now there is only one Preferences menu where you can adjust all your settings.
Big thinkers think about giving, doing, and ideas. Small thinkers think about getting and having. If you’re comparing to or gossiping about others — you’re not thinking at all.
