Our journey from office-centric to remote-first
Docker Inc. started like many startups with engineers working from a single location. For us, this was in the Bay Area in the US. We were very office-centric, so the natural way to increase diversity and to get engineers from different cultures to work together was to open new offices in diverse locations. Right from the start, our goal was to mix American and European ways of producing software, giving us the best of both cultures.
Step 1 – Opening European offices
In 2015, Docker started to open offices in Europe, starting with Cambridge in the United Kingdom and followed by Paris in France. With these two locations, the long road to gaining experience working with remote employees began.
Having multiple offices scattered around the world is different from being fully remote. But you still start experiencing some of the challenges of not having everybody in the same location simultaneously. We spent a great deal of our time on planes or trains visiting each other.
Despite the robust open-source culture of the company, which shows that you can build great software while not having everybody in the same room, we still had a very office-centric culture. A lot of the Continue reading
Routing Protocols: Use the Best Tool for the Job
When I wrote about my sample OSPF+BGP hands-on lab on LinkedIn, someone couldn’t resist asking:
I’m still wondering why people use two routing protocols and do not have clean redistribution points or tunnels.
Ignoring for the moment the fact that he missed the point of the blog post (completely), the idea of “using tunnels or redistribution points instead of two routing protocols” hints at the potential applicability of RFC 1925 rule 4.

A Tale Of Two Enterprise IT Beasties
The so-called “Magnificent 7” or “Super 8” hyperscalers and cloud builders of the world may comprise a substantial slice of worldwide sales of servers, storage, and networking, and the cloud capacity and hyperscale services they provide may in turn represent a significant – but nowhere near dominant – chunk of overall IT spending. …

Dr. Kanchana Kanchanasut: On Connecting with Communities
Dr. Kanchana Kanchanasut is defined by many firsts. She is well known for being the first Thai to establish email connection to the world. She was among the pioneers to establish Thailand’s research and education network. She registered the .th domain name, conducted Thailand’s first TV White Spaces trial, and started the first open and […]

Review: 2020 M1-Based MacBook Pro
I hadn’t done a personal hardware refresh in a while; my laptop was a 2017-era MacBook Pro (with the much-disliked butterfly keyboard) and my tablet was a 2014-era iPad Air 2. Both were serviceable but starting to show their age, especially with regard to battery life. So, a little under a month ago, I placed an order for some new Apple equipment. Included in that order was a new 2020 13" MacBook Pro with the Apple-designed M1 CPU. In this post, I’d like to provide a brief review of the 2020 M1-based MacBook Pro based on the past month of usage.
The “TL;DR” of my review is this: the new M1-based MacBook Pro offers impressive performance and even more impressive battery life. While the raw performance may not “blow away” its 2020 Intel-based counterpart—at least, it didn’t in my real-world usage—the M1-based MacBook Pro offered consistently responsive performance with a battery life that easily blew past any other laptop I’ve ever used, bar none.
Read on for more details.
Hardware
The build quality is really good, with a significant improvement in keyboard quality relative to the earlier butterfly keyboard models (such as my 2017-era MacBook Pro). However, the overall design Continue reading
Day Two Cloud 100: Get To Know Crossplane: An Infrastructure Control Plane For K8s
Crossplane is an open-source project that plugs into Kubernetes to serve as a control plane that can run across multiple private and public clouds. It allows infrastructure teams to compose infrastructure with all the required policies, permissions, and guardrails, while also providing APIs for developer self-service. Today's Day Two Cloud podcast dives into Crossplane and how it works with maintainer Daniel Mangum.Day Two Cloud 100: Get To Know Crossplane: An Infrastructure Control Plane For K8s

Unnumbered Ethernet Interfaces
Imagine an Internet Service Provider offering Ethernet-based Internet access (aka everyone using fiber access, excluding people believing in Russian dolls). If they know how to spell security, they might be nervous about connecting numerous customers to the same multi-access network, but it seems they have only two ways to solve this challenge:
- Use private VLANs with proxy ARP on the head-end router, forcing the customer-to-customer traffic to pass through layer-3 forwarding on the head-end router.
- Use a separate routed interface with each customer, wasting three-quarters of their available IPv4 address space.
Is there a third option? Can’t we pretend Ethernet works in almost the same way as dialup and use unnumbered IPv4 interfaces?

How Do Surveillance Laws Impact the Economy?
In 2018 the Australian parliament passed the “TOLA” Act, expanding the government’s powers to bypass digital data protections, and bringing with it the potential for significant harm to the economy and to trust in digital services and the Internet. Under TOLA, law enforcement and security agencies can require “designated communications providers,” or other businesses associated […]
