Software & tech enthusiast living in Switzerland, working @ Datadog. Opinions on all sorts of things, some of them reasonable.
Come listen to @jameseastham.co.uk and I ramble about software architecture!
Picture the scene, you've been asked to build a brand new product in a brand new domain? How do you actually understand if you're building the right thing?
Join me and @scottgerring.com in this video where we discuss the #1 place to start when building new software?

The #1 Place To Start Designing New Software
Hi, I'm James Eastham, a developer advocate at Datadog, and in this video, I team up with my colleague Scott Gerring to share a strategic approach to designing new software. We delve into the importance of focusing on user needs rather than technology from the get-go. Our journey starts with exploring 'domain storytelling,' a technique to better understand systems by mapping out user interactions, work items, and backend systems. We use a hypothetical app, 'Sticker Landia,' to illustrate our approach and show how it can lead to meaningful, user-focused software design. Join us as we highlight the steps to map out service boundaries and set the groundwork for building effective software solutions. Drop your thoughts and suggestions in the comments and don't forget to subscribe for more insights into modern software engineering! 00:00 Introduction: The Right Way to Start Designing Software 01:22 Problem Statement: The Sticker Landia App 02:42 Understanding...

This is clever realization - you can use XDP also for fast **egress** by cleverly using veth pairs - #ebpf community continues to do wildly novel things !

Using XDP for Egress Traffic
XDP only works for ingress. We found a loophole that lets it work for egress. Here's how we did the impossible.

Google Slides diff view is surprisingly good? You can click through changes, and you get a big coloured box around what shifted.
... I kinda assume decent diffing was never gonna be a thing for presentations that _aren't_ written in some md/js framework

So this is fucking gross - the US is trying to pressure the EU, again with the threat of tariffs, to water down their environmental regulations.

"look up and stay present" .. by "collaborating with visual Meta AI prompts" projected between your eyes and the folks _in the real world you are notionally trying to stay present with_.
I don't understand if they are trying to redefine what 'present' means or they are just too deep in this rubbish

Becoming increasingly clear we’re gonna have to build a parallel infrastructure for all the media we really love. The reason all of this is happening under the color of law is hyperconsolidation, dissent being traded straight up for merger approval, or fear of harassment.

Hey #jj folks, I am trying to write a idiomatic revset that finds the earliest change that diverged from main, so I can rebase a stack of changes onto the latest main when they diverge. The best I can do is:
(::@ ~ ::main) & roots(::@ ~ ::main)
Which strikes me as rather gnarly. Easier way?!

Last week I needed to check that the PoE network port for my night-vision doorbell was working, so I plugged a usb-c network adapter into my iphone and ran a speed test over it. What a world we live in!

Spent _literally hours_ crimping and crimping again network cables trying to make my fancy doorbell work, only to realise I’d bought single mode fiber for the switch backhaul and that sorta kinda works with multimode transceivers but not like … good.

A fun part of working on cargo-pup, an architectural linting tool for #rust, is that I have to periodically fix things up to match changes in rustc's codebase. Little peaks behind the curtain into the compiler's internals.

I’ve been working on cargo-pup, a Rust tool for defining and enforcing architectural rules in your codebase - like ArchUnit for Java, or Clippy, but for project-specific architecture constraints rather than linting.
Would love feedback from other rust folks!

Did you know that you can use the OpenTelemetry Java APIs without setting up an export pipeline in your code? (I didn't)
Add the opentelemetry-api dep, sprinkle @WithSpan on your important business-things, and let your auto-instrumentation wrapper - e.g. dd-trace-java - discover the OTel API usage!
