Cloudflare K2 is a serverless event streaming service built directly on top of R2 object storage for high-scale data movement and long-term retention. By decoupling producers and consumers at the edge, K2 enables durable, ordered log streams without the operational overhead of traditional broker clusters.

Solar and batteries are cheap enough that most people can get most of their electricity from them, and save money. This equation gets better and better over time as their costs decline.
Today i bring the working main camera! Building on the work nondescriptpointer did on the wide lens camera i have written the driver for the main camera and now its working alongside auto focus and color correction. The color correction still a work in progress, but you can…
If xAI defaults on its debt, Apollo Global Management ends up in the GPU rental business.
In late 2025 the company behind MinIO decided to abandon it to pursue other commercial interests. As well as upsetting a bunch of folk, it also put the cat amongst the pigeons of many software demos that relied on MinIO to emulate S3 storage locally, not to mention build pipelines that used it for validating S3…

So I've been job hunting lately. Reading job postings, doing interviews, talking to engineering teams at like a dozen companies. And I noticed...
How OpenAI built Pando, a Git-compatible backend designed for the scale of development that Codex makes possible.
zeroserve is a small, fast, zero-config HTTPS server. You hand it a tarball of a website and it serves it - over HTTP/2 and TLS 1.3, with hot reload and a tiny resident footprint. The twist is that you can drop eBPF programs into the tarball and they run on every request, in userspace, as sandboxed middleware …
Thanks HN folks for all the comments. To clarify a bit, the cables are pulled through PVC conduits under the flooring before being buried in cement. Currently the hypothesis for why the cable disintegrated so quickly is hydrolysis. Singapore is extremely humid after all. A second possibility is that I keep the…
A few months after writing up the Cudy AX3000 units and moving the house over to OpenWRT, I ended up revisiting the one bit I had deliberately waved away ...
When code gets cheap operational excellence wins. Anyone can build a greenfield demo, but it takes engineering to run a service.
Why do our grids show a brief spike in electricity demand every minute? A team led by Dirk Witthaut from Forschungszentrum Jülich has now demonstrated that this is due to regular power checks carried out by large-scale battery storage systems. These findings could help to make our electricity supply more robust, as…
If you happen to find yourself in a sysadmin position, or a position where you just so happen to maintain someone’s infrastructure , chances are that at some point in time the topic “we need a cache” comes up.
Recently Ben Hoyt published a blog post claiming that contrary to popular belief, I/O is not the bottleneck in typical programming interview problems such as counting word frequencies from a stream. Sequential read speed has come a long way, while CPU speed has stagnated.
Docker Inc's journey from containerization pioneer to AI-focused platform has been anything but straightforward. Here's what their strategic shifts tell us about the company's search for identity.
PgDog is a connection pooler, load balancer, and sharding proxy for PostgreSQL. Scale Postgres horizontally without rewriting your application.
Bun 1.4 rewrites Bun in Rust, ships built-in headless browser automation (Bun.WebView), Bun.Image, Bun.markdown, JSON5, JSONL, Terminal and cron APIs, Node.js 26.3.0 compatibility with 1,517 newly passing tests, parallel test and run, Windows ARM64, and an opt-in global virtual store for up to 7× faster installs.
Cloudflare Research is building a global consensus service called Meerkat that uses a new consensus algorithm called QuePaxa. We plan to use Meerkat to build a strongly consistent, fault-tolerant key-value store, and other applications.
My micro site, zero.btxx.org , is being served to the public internet from a Raspberry Pi Zero v1.3 running Alpine Linux.
Anne Robinson would like a word with .github/workflows
We’ve expanded our eighth generation TPU portfolio with TPU 8tx and TPU 8i Max, marking four new TPU systems in a single year.
The increasing demand for GPU-accelerated machine learning inference has exposed limitations in centralized GPU infrastructures, including…
I just want S3. My needs are pretty basic. I don't need to scale out. I don't need replication. I just need something that can do S3 and is reliable and not slow. Minio is dead, they pulled the plug after axing the interface. They archived the repo so they …
It all started in the winter of 2024. There was a burglary in our apartment building and we decided we needed to invest in our home’s security. The …
