Time For Improvement

Welcome to 2020! First and foremost, no posts from me involving vision or eyesight or any other optometrist puns for this year. I promise 366 days free of anything having to do with eyeballs. That does mean a whole world of other puns that I’m going to be focusing on!

Now, let’s look back at 2019. The word that I could use to describe it was “hectic”. It felt like everything was in overdrive all year long. There were several times that I got to the end of the week and realized that I didn’t have any kind of post ready to go. I’m the kind of person that likes to write when the inspiration hits me. And instead I found myself scrambling to write up some thoughts. And that was something I told myself that I was going to get away from. So we’re going to call that one a miss and get back to trying to post on a day other than Friday.

That also means that, given all the other content that I’ve been working on with Gestalt IT that I’m going to have to schedule some time actually working on that content instead of hoping that Continue reading

Getting Started with the Rust Programming Language

A programming language that has begun picking up momentum in the community lately is Rust. This is a guide aimed at helping folks get started with the Rust Programming Language. Rust has been around for a while with a stable v1.0 shipping in 2015. Rust initially came from Mozilla who maintain the multi-million line C++ codebase in Firefox that has ...

5G is poised to transform manufacturing

5G promises not just super-fast connections and more bandwidth than Wi-Fi and 4G LTE but also better connectivity, low latency, and support for thousands of devices in one location, all of which are attractive manufacturing facilities, but it will be a while before it becomes the norm there, experts say.According to Gartner, smart factories are major opportunities for 5G. While some use cases can be achieved with existing 4G LTE, most require the low latency and high reliability offered by 5G.To read this article in full, please click here

Returning to First Principles

I feel very strongly (and have for some time) that fundamentals are really important in a technical career. I didn’t start my career with a traditional CS degree, and while there were some fundamental knowledge to be picked up along the way, much of my education and early work experience bypassed a lot of the lower-level fundamentals and placed heavy emphasis on operating technology. This feeling of pulling levers and pushing buttons, rather than actually building things, in large part was responsible for me shifting back into software development full-time.

Looking Back: 2019 Project Report Card

As has been my custom over the last five years or so, in the early part of the year I like to share with my readers a list of personal projects for the upcoming year (here’s the 2019 list). Then, near the end of that same year or very early in the following year, I evaluate how I performed against that list of personal projects (for example, here’s my project report card for 2018). In this post, I’ll continue that pattern with an evaluation of my progress against my 2019 project list.

For reference, here’s the list of projects I set out for myself for 2019 (you can read the associated blog post, if you like, for additional context):

  1. Make at least one code contribution to an open source project. (Stretch goal: Make three code contributions to open source projects.)
  2. Add at least three new technology areas to my “learning-tools” repository. (Stretch goal: Add five new technology areas to the “learning-tools” repository.)
  3. Become more familiar with CI/CD solutions and patterns.
  4. Create at least three non-written content pieces. (Stretch goal: Create five pieces of non-written content.)
  5. Complete a “wildcard project” (if applicable).

Here’s how I Continue reading

Member News: Internet Society Highlights from 2019

It’s been a busy year for Internet Society Chapters around the world, with members pushing to extend Internet connections to remote areas, involved in public policy, and focusing on cybersecurity. Here are some of the highlights in 2019:

Extending Internet connections

Community awareness: The Madagascar chapter provided awareness training on community-based broadband networks in the rural areas of Ambohimasina, Antambolo, and Morarano-Antongona during February and March. “Our main objective was to ensure that people using the Internet continue to be convinced of its usefulness,” the Chapter wrote. Another goal was for local leaders to have access to the Internet for the “purposes of innovation, creativity and economic opportunities for their municipality.”

Network planning: In Nigeria, the Internet Society Chapter began planning to set up a community network in Zaria, a city in the northern region of the country. The Internet Society provided startup funds of about 10 million naira, or “about the cost of a fairly used Toyota Corolla,” the Chapter noted. “By being very frugal and leveraging on existing infrastructure being contributed by community members, this will cover the cost of the initial wireless hardware required to connect at least 12 locations across Zaria.”

Adopting a new approach to HTTP prioritization

Adopting a new approach to HTTP prioritization
Adopting a new approach to HTTP prioritization

Friday the 13th is a lucky day for Cloudflare for many reasons. On December 13, 2019 Tommy Pauly, co-chair of the IETF HTTP Working Group, announced the adoption of the "Extensible Prioritization Scheme for HTTP" - a new approach to HTTP prioritization.

Web pages are made up of many resources that must be downloaded before they can be presented to the user. The role of HTTP prioritization is to load the right bytes at the right time in order to achieve the best performance. This is a collaborative process between client and server, a client sends priority signals that the server can use to schedule the delivery of response data. In HTTP/1.1 the signal is basic, clients order requests smartly across a pool of about 6 connections. In HTTP/2 a single connection is used and clients send a signal per request, as a frame, which describes the relative dependency and weighting of the response. HTTP/3 tried to use the same approach but dependencies don't work well when signals can be delivered out of order.

HTTP/3 is being standardised as part of the QUIC effort. As a Working Group (WG) we've been trying to fix the problems that non-deterministic ordering Continue reading

New Year, New Adventure

I’ll skip the build-up and jump straight to the whole point of this post: a once-in-a-lifetime opportunity has come up and I’m embarking on a new adventure starting in early 2020. No, I’m not changing jobs…but I am changing time zones.

Sometime in the next month or two (dates are still being finalized), I’ll be temporarily relocating to Tokyo, Japan, to help build out VMware’s Cloud Native Field Engineering team to provide consulting and professional services around cloud-native technologies and modern application platforms for customers in Japan. Basically, my charter is to replicate the former Heptio Field Engineering team (now the Cloud Native Field Engineering Practice within VMware) in Japan.

Accomplishing this feat will involve a variety of responsibilities: a pretty fair amount of training/enablement, engaging customers on the pre-sales side, helping lead projects on the post-sales (delivery) side, mentoring team members, performing some project management, probably some people management, and the infamous “other duties as required.” All in about six months (the inital duration of my assignment), and all while learning Japanese! No big deal, right?

I’m both simultaneously excited and scared. I’m excited by the idea of living in Tokyo, but let’s be honest—the language barrier is Continue reading
