Technology Short Take 108

Welcome to Technology Short Take #108! This will be the last Technology Short Take of 2018, so here’s hoping I can provide something useful for you. Enjoy!

  • Maish Saidel-Keesing has a 5-part series on replacing the AWS ELB. This is an older post (from August) that I’ve had in my backlog for a while, and I’m just now getting around to reading the series. There’s some really good information in here. I won’t link to all five, but rather just point you at the introductory post (and Maish has done a great job—better than a lot of bloggers—making the entire series easily accessible).
  • Quentin Machu delves deep into an obscure DNS resolution issue that was introducing seemingly-erratic delays with DNS lookups. Quentin’s post is very detailed, and has lots of good information.
  • Anthony Burke has some information on preparing a node for Kubernetes and the NSX NCP.
  • Benjamin Dale suggests that you don’t know JunOS.

Towards a theory of software development expertise

Towards a theory of software development expertise Baltes et al., ESEC/FSE’18

This is the last paper we’ll be looking at this year, so I’ve chosen something a little more reflective to leave you with (The Morning Paper will return on Monday 7th January, 2019). The question Baltes and Diehl tackle is this: “How do you get better as a software developer?” What does expert performance look like?

We present a first conceptual theory of software development expertise that is grounded in data from a mixed-methods survey with 335 software developers and in literature on expertise and expert performance…. [the theory] describes central properties of software development expertise and important factors influencing its formation.

In essence, ask a bunch of practitioners what they think, use a disciplined coding scheme to interpret the answers (a “grounded theory”), and then layer in what we know about expertise and expert performance in general. The end result is a “conceptual theory” that shows the various contributors to expert performance and the relationships between them. “Software Development” in the current work is synonymous with “programming.”

To make the paper come alive you need to engage with it a little: Does the theory developed Continue reading

Speak at DockerCon San Francisco 2019 – Call for Papers is Open

 

Whether you missed DockerCon EU in Barcelona, or you already miss the fun, connections and learning you experienced at DockerCon – you won’t have to wait long for the next one. DockerCon returns to San Francisco on April 29 and extends through May 2, 2019 and the Call for Papers is now open. We are accepting talk submissions through January 18th at 11:59 PST.

Attending DockerCon is an awesome experience, but so is speaking at DockerCon – it’s a great way to get to know the community, share ideas and collaborate. Don’t be nervous about proposing your idea – no topic is too small or too big. And for some speakers, DockerCon is their first time speaking publicly. Don’t be intimidated, DockerCon attendees are all looking to level up their skills, connect with fellow container fans and go home inspired to implement new containerization initiatives. Here are some suggested topics from the conference committee:

  • “How To” type sessions for developers or IT teams
  • Case Studies
  • Technical deep dives into container and distributed systems related components
  • Cool New Apps built with Docker containers
  • The craziest thing you have containerized
  • Wild Card – anything and everything!
  • The Continue reading

Gnome3 Customise Shell Theme

I recently re-installed Ubuntu 1804 on my laptop and I though I would give the PopOS desktop theme from system76 a try. The verdict? It's very very nice. Next time I do a re-install or get a new laptop I think I will use PopOS which is based in Ubuntu anyway. Side note: If a System76...

IBM Bets On Samsung Fabs For Power10 Chips

When Globalfoundries decided to stop its development and rollout of both immersion lithography and extreme ultraviolet (EUV) lithography at the 7 nanometer process node back in August, it looked as if IBM, second only to AMD as a server chip customer for its most advanced fab in Malta, New York, would be left in a lurch with its future Power processors. …

BrandPost: 5 Steps to Get Ready for 802.11ax

It’s a mobile, cloud and IoT world. Whether it’s a workplace, a classroom or a dorm room, people are using a variety of devices beyond the usual phone and laptop combo—smart TVs, gaming consoles and fitness trackers, for starters. Offices, stores and manufacturing floors are outfitted with sensors that keep us safe, regulate the temperature, water the plants and run the production line. People use a broad variety of applications such as voice and video from their mobile devices. And expectations are at an all-time high. People will simply ditch digital services that don’t work. No one wants jittery presentations and dropped calls. The network experience must be flawless.To read this article in full, please click here

IDG Contributor Network: Can TLS 1.3 and DNSSEC make your network blind?

Domain name system (DNS) over transport layer security (TLS) adds an extra layer of encryption, but in what way does it impact your IP network traffic? The additional layer of encryption indicates controlling what’s happening over the network is likely to become challenging.Most noticeably it will prevent ISPs and enterprises from monitoring the user’s site activity and will also have negative implications for both; the wide area network (WAN) optimization and SD-WAN vendors.During a recent call with Sorell Slaymaker, we rolled back in time and discussed how we got here, to a world that will soon be fully encrypted. We started with SSL1.0, which was the original version of HTTPS as opposed to the non-secure HTTP. As an aftermath of evolution, it had many security vulnerabilities. Consequently, we then evolved from SSL 1.1 to TLS 1.2. To read this article in full, please click here
