Since OpenTelemetry first introduced Profiles, momentum has only grown towards building a unified industry standard for continuous production profiling, standing alongside traces, metrics, and logs. Today, the Profiling SIG is proud to announce that the Profiles signal has officially entered public Alpha, and we are…
My homepage now runs on OpenBSD with httpd(8) and Let's Encrypt via acme-client(1) . I previously hosted it on GitHub Pages and then eventually moved to Cloudflare Pages because both options were free and easy. Free and easy is cool, and I understand that writing software full-time leaves us wanting absolutely nothing…
Something funny happened a little while ago: I read about FreshRSS, and it sounded nice, so I installed it on a server and started using it . That would not have happened a year ago, but then again, a year ago I didn’t have any NixOS servers.
Oracle cut its Always Free ARM limits to 2 OCPU / 12GB, enforced Aug 18, 2026. Resize or consolidate your free instances before they're terminated.
Justin Cormack, who worked on MirageOS back in the day, called me at the pub to talk about why unikernels are coming back. The friction that made them hard is gone, the operating system is design debt, and if you care about security you should seriously consider them.
How customer needs shaped Oxide's Kubernetes integrations.
We are launching Workers Cache, a regionally tiered cache that sits directly in front of your Worker entrypoints. Infinitely composable, configured via standard HTTP headers

Remember Tarus Balog, the AWS employee who rescued my deleted account when nobody else would? AWS just fired him. His proudest accomplishment in four years was saving my data. Leadership didn't care. The finale of a trilogy nobody asked for.
As predicted by several people, one of my Marvell-based SFP+ modules had overheating problems. I've switched it over to a Broadcom-based one, and it looks better, though I can't be certain.
Healthchecks.io ping endpoints accept HTTP HEAD, GET, and POST request methods. When using HTTP POST, clients can include an arbitrary payload in the request body. Healthchecks.io stores the first 100kB of the request body. If the request body is tiny, Healthchecks.io stores it in the PostgreSQL database. Otherwise…
After 5 years in DevOps, I moved into Solutions Engineering. Here’s what I was missing, what changed, and who this path might be for.
A practical guide to building a SaaS product on a 100% European stack: hosting, payments, CDN, analytics, and transactional email.
On 11th February, Let’s Encrypt will be rolling out a change to the certificates they issue to servers by default. Although there is generally nothing that Prosody operators need to do, servers using the new certificates may experience problems connecting to some other XMPP servers on the network.
I let AWS Cognito gaslight me for three weeks so you don't have to. Here's the unfiltered autopsy.
Cloudflare suffered a service outage on February 20, 2026. A subset of customers who use Cloudflare’s Bring Your Own IP (BYOIP) service saw their routes to the Internet withdrawn via Border Gateway Protocol (BGP).
Every agent tool stores memory in its own shape, and every week someone builds another one. None of them can read the others. Observability had the same problem until OpenTelemetry gave everyone one data model to share. A tour of today's memory formats, the proposals that already exist, and what a shared spec could…
Aiming for a 10 year life-cycle for smartphones
We moved our warehouse product off DuckDB and DuckLake onto our own flavor of Trino and a new open table format, HogLake. Here's what broke at scale and why.

In an easterly suburb of Mykolaiv, drinking water flowed from kitchen taps, as it has since last year thanks to a small off-grid solar field tucked inconspicuously into its midst. Paul Hockenos reports.
