  • The Dark Secret at the Heart of AI
    No one really knows how the most advanced algorithms do what they do. That could be a problem.
  • The Threat
    There were only a few application areas [of information security] that people really worried about thirty years ago: diplomatic and military communications at one end, and the security of things like cash machines at the other. As we’ve gone about putting computers and communications into just about everything that you can buy for more than ten bucks that you don’t eat or drink, the field has grown.
  • Inside Chrome: The Secret Project to Crush IE and Remake the Web
    Why is Google building a browser? A better question is, why did it take so long for Google to build a browser?
  • WWW: The Way We Were
    The final two episodes of Halt and Catch Fire aired last night. […] The Web that they are talking about on the show, the open Web, is ailing, dying. It was like listening to a eulogy at a funeral, this thing that I love, poured the best of my self into, gone forever.
  • Everything Is Fucked and I’m Pretty Sure It’s the Internet’s Fault
    Democracy relies on trust. Rule of law requires trust. If we lose our trust in our institutions, then those institutions will either crumble or turn cancerous. But the internet lines up incentives in such a way that it makes it profitable to breed distrust.
  • The Real Name Fallacy
    The idea that anonymity is the real problem with the internet is based in part on misreadings of theories formed more than thirty years ago.

  • AWS Security Primer
    I was preparing some AWS Security related training. Soon, I realized that this topic is too huge to fit into my brain. So I structured my thoughts in a mind map. Within a couple of minutes1 I came up with this.
  • Takeaways From the ServerlessConf 2017
    Serverless computing basically adds another layer of abstraction on top of cloud infrastructure so that the developer doesn’t need to worry about servers, including virtual ones.
  • How Much Does It Cost To Run A Serverless API on AWS? · Alestic.com
    Folks tend to be curious about how much real projects cost to run on AWS, so here’s a real example with breakdowns by AWS service and feature. During this month, TimerCheck.io service processed over 2 million API requests.
  • How Google Is Challenging AWS
    Big companies are often criticized for having “missed” the future — from the comfortable perch of a present where said future has come to pass, of course — but while the future is still the future incumbents are first more often than not.
  • Best Practices for Building a Microservice Architecture
    A microservice architecture shifts around complexity. Instead of a single complex system, you have a bunch of simple services with complex interactions. Our goal is to keep the complexity in check.
  • How the Internet works: Submarine fibre, brains in jars, and coaxial cables
    Have you ever thought about how that cat picture actually gets from a server in Oregon to your PC in London? We’re not simply talking about the wonders of TCP/IP or pervasive Wi-Fi hotspots, though those are vitally important as well. No, we’re talking about the big infrastructure: the huge submarine cables, the vast landing sites and data centres with their massively redundant power systems, and the elephantine, labyrinthine last-mile networks that actually hook billions of us to the Internet.

On tools …

  • Setting the Record Straight: containers vs. Zones vs. Jails vs. VMs
    Solaris Zones, BSD Jails, and VMs are first class concepts. [..] Containers on the other hand are not real things.
  • CPU Utilization is Wrong
    The metric we all use for CPU utilization is deeply misleading, and getting worse every year. What is CPU utilization? How busy your processors are? No, that’s not what it measures. Yes, I’m talking about the “%CPU” metric used everywhere, by everyone.
  • Practical jq
    I really love jq, the JSON processor. It has changed my life and pretty much replaced Perl and Ruby as my ETL and data-munging go-to tools.
  • Reshaping JSON with jq
    Working with data from an art museum API and from the Twitter API, this lesson teaches how to use the command-line utility jq to filter and parse complex JSON files into flat CSV files.
  • A Visual Guide to What’s New in Swagger 3.0
    Over the past few years, Swagger 2 has become the de facto standard for defining or documenting your API. Since then, it’s been moved to the Linux foundation and renamed to OpenAPI Spec.
  • A plan for open source software maintainers
    As I envision it, a solution would look something like a cross between Patreon and Bugzilla: Users would be able sign up to “support” projects of their choosing […] and would be able to open issues.

  • Trump, Putin and the Pipelines to Nowhere
    A crisis in investor confidence is the biggest threat to fossil fuel companies — not environmentalists, regulations, clean energy competitors or climate agreements.
  • The 1930s were humanity’s darkest, bloodiest hour. Are you paying attention?
    Even to mention the 1930s is to evoke the period when human civilisation entered its darkest, bloodiest chapter. No case needs to be argued; just to name the decade is enough. It is a byword for mass poverty, violent extremism and the gathering storm of world war.
  • When It’s Too Late to Stop Fascism, According to Stefan Zweig
    The excruciating power of Zweig’s memoir lies in the pain of looking back and seeing that there was a small window in which it was possible to act, and then discovering how suddenly and irrevocably that window can be slammed shut.
  • Torching the Modern-Day Library of Alexandria
    When the library at Alexandria burned it was said to be an “international catastrophe.” When the most significant humanities project of our time was dismantled in court, the scholars, archivists, and librarians who’d had a hand in its undoing breathed a sigh of relief, for they believed, at the time, that they had narrowly averted disaster.
  • Die Globale Klasse – Eine andere Welt ist möglich. Aber als Drohung.
    Es gibt heute eine globalisierte Klasse der Informationsarbeiter, der die meisten von uns angehören und die viel homogener und mächtiger ist, als sie denkt.
  • Wie politisch darf, soll oder muss eine Firma sein?
    In kleinen und großen Gruppen sind wir auf der ganzen Welt und in unterschiedlichsten Kulturkreisen unterwegs. Die Vorbehaltlosigkeit und das Interesse, welches uns überall entgegengebracht wird, hat auch jeder andere verdient. Und dafür stehen wir als Open Source Company in besonderem Maße.

A few notes on monitoring, debugging, and testing.

  • Chris’s Wiki : blog/unix/ManyLoadAveragesOfUnix
    It turns out that the meaning of ‘load average’ on Unixes is rather more divergent than I thought it was. So here’s the story as I know it.
  • Illustrated Guide to Monitoring and Tuning the Linux Networking Stack: Receiving Data
    This blog post expands on our previous blog post Monitoring and Tuning the Linux Networking Stack: Receiving Data with a series of diagrams aimed to help readers form a more clear picture of how the Linux network stack works.
  • Using jemalloc to get to the bottom of a memory leak
    The opportunity to really get to the bottom of a memory problem is quite a rarity in the life of a developer and this showed in the fact that our investigations (alongside other work) lasted over a month.
  • Ten Tired Trends In Software Testing Discourse
    I’ve read your blog posts and I’ve been to your talks and talked to you after the talks too. And here’s what I want to know: if you love automation so much how come all you can do is warn me about how not to use it?
  • Notes on concurrency bugs
    Non-deterministic bugs are rare, but they can be extremely hard to debug and they’re a productivity killer. Bad non-deterministic bugs take so long to debug that relatively large investments in tools and prevention can be worth it.
  • Why Writing Correct Software Is Hard
    The cost of correctness – like the energy cost of reducing entropy – is a result of the “natural laws” of computation, that cannot possibly be avoided.
