System Architecture

Cloud native chaos engineering ensures that every component responsible for an entire application’s proper functioning is resilient.

Is is better to use API Gateway Edge or Regional deployments on AWS?

The idea was to remove central points of failure, not introduce them

In which a little unfairness can be quite beneficial

Last week I was studying outside of a lecture hall where someone was teaching an introductory course on computer programming. There was a lot that I overheard that I disagreed with; this essay is an attempt to help me crystallize what exactly I disagreed with.

Recently we had to tackle a seriously strange bug. A customer reported that under a specific set of circumstances, when loading the database with many concur...

It's surprisingly hard to make a map today, and people in 15+ industries rely on them to do their jobs. Felt is the first easy-to-use collaborative mapping app, on mission to help everyone think in maps.

Flatter hierachies, fewer hops: Rockport and the Torus interconnect

Rockport Networks has exited stealth with a switchless datacentre network product that it claims can carry data traffic faster and with better latency than switched networks, yet is a drop-in replacement for Ethernet and InfiniBand cabling and switches with no application software changes. It says switch-based networks are reaching a dead-end of increased complexity and […]

Token-based identity systems move us from talking about who, to thinking about what, so that people can operationalize their digital lives. Token-based identity systems support complex online interactions that are flexible, ad hoc, and cross-domain.

It's common for me to get excited about a personal project, put a bunch of time into it, and then lose interest. As much as possible, I want these projects to continue working; upkeep isn't fun. What does designing for minimum maintenance look like? The biggest piece is minimizing your dependencies, and limiting them to ones that value backwards compatibility. Most of my projects are on the web, which means I have an unavoidable dependency on browsers, but this is fine because browsers strongly prioritize keeping existing websites working. On the server I run Ubuntu LTS until it's near the end of its supported lifetime. Every two years I run do-release-upgrade and move to the next one. This cost is shared over manyjefftk.com projects, so it isn't too bad. Many projects can just be hand-written HTML/JS/CSS. No build system, no libraries, just speaking the browser's native languages. These don't need any technical maintenance; they just keep working. One step from there are projects where I need a little bit of server-side support. For example, I write my blog posts as plain HTML, but I need headers, footers, indexes, and RSS. Each time I change my site I run a scriptwhich creates/updates all these additional files. If I want to change something about the presentation of my site then I need to dig into code, and very occasionally something will break when updating the site, but just displaying my existing stuff doesn't require any maintenance. Then we get to the tricky stuff: projects which need real time custom code. Things like Bucket Brigade and blog comment inclusion. How I approach this: * Code in python, with no dependencies beyond the standard library. As with browsers, python rarely drops support for widely used functionality. Moving to python3 was a bit annoying, but I waited a long time and then used 2to3. Avoiding dependencies made this easy. * Store data on the file system, including for caching. It's not as elegant as a prope

Today is my birthday which means I've been coding for 25 years. A quarter century 😱 Here's 25 lessons I've learned about code. In no particular order.

Building your own browser sounds like a terrible idea, especially if you’re a front-end developer by trade and don’t know any C++ or other native language. Even so a couple of years ago I decided to see if I could and by now my browser has developed into a serious project. How’d I get the […]
