Jan Skalla's write-up of last week's kernel CVE.
What algif_aead + splice() actually does to the page cache and why it lands deterministically on every distro.
Our node-by-node rollout across two regions, including the call to deliberately slow it down mid-flight.
And why HA services rode through emergency kernel maintenance without a single alert, while non-HA took a brief blip.
Link below.

28 Weeks Later 👀
Over 6 months ago we acquired and re-launched Zerops, a platform we've been developing since 2019. And we worked hard to add support for new services, improve developer experience, flexibility and our infrastructure layer.
See our 2024 recap / 2025 plans 👇

The only difference between environments should be precisely controlled resources — environment parity ships stable apps. Deploy one-click production-ready Laravel, Jetstream, Filament, TwillCMS examples on our resource-efficient PaaS. Ready in minutes, $65 credits, no CC needed.

We continue to improve debuggability of Zerops — now giving you the ability to pause pipeline processes and access involved containers via remote web terminal (build & runtime prepare).
Aleš@fxckdev_
Pretty proud about this one — a big quality of life improvement to @zeropsio. When you are deploying applications, the most annoying thing (not exclusive to Zerops) is when some build process works fine locally but doesn't in your CI/CD setup. You end up endlessly deploying new versions, ls-ing, pwd-ing, apt-ing, printing, and chmod-ing your way through with tens of pipeline triggers. It's frustrating no matter if you're trying out Zerops for the first time or are a power user (and believe me, we would know, being the biggest power users of our platform ourselves — the countless hours this has consumed over the years). And so, building on top of the remote web terminal access to runtime containers we've added recently, we are introducing remote web terminal access to build & runtime prepare containers. To be able to properly debug, we've added settings for pipeline debug options, which allows you to control pipeline behavior, telling the process to stop at certain points (before, after commands, and on commands fail), giving you time to access the container, debug, run commands manually, and eventually even resume the process.

@ibuildthecloud 🤔 JuiceFS + S3? Tested this for @zeropsio It works but watch out for heavy cache usage and S3 latency. You'll also need a metadata store like Redis. While you can tune cache/throttling configs, it's always a performance vs resource tradeoff.
English
I really wish there was a FUSE filesystem that was backed by S3 that actually worked. Does this exist?

We are speeeeding up. See how proper tracing helped us speed up Zerops up to 10x across our entire platform. From API calls to spinning up your next project — everything's faster now. 🚀

Just the beginning! More coming:
- Incus "microvms"
- Enter failed build containers, fix & continue
- Further speed improvements
All to make onboarding smoother, project cloning faster, and deployments more developer-friendly. 🙏

🚨 So excited to announce a partnership between @AnalogJS and @zeropsio that continues to invest in the @Angular ecosystem, and build out a Dev-first cloud platform!

We've recently added @qdrant_engine, a vector database, as a managed service on Zerops. @jansaidl shares our journey in implementing a high-availability setup in this detailed blog post

@fxckdev_ @reconditerose @zeu_dev @saucedopen @realkeydb Hey, our usecase is to provide HA key value database.
To setup a Multi-Master in KeyDB is really simple.
In Valkey you need a master-replica setup and a sentinel protocol to detect the master container.
It is a pity that valkey replica cannot forward write requests.
English
Hey @reconditerose, that's great to hear! @jansaidl will surely let you know, he's been trying to get Valkey working in HA for a couple of days now, so he has a direct comparison as well.
Note that we are working on a PaaS, so we are offering KeyDB (and soon Valkey hopefully) as semi-mamaged services.

I wanted to see how Redis is doing after their branding and license change earlier this year.
Sometimes you can see the story in the data.
Redis@Redisinc
You know our name. Meet our new brand. Same Redis, still fast.

We're adding native support for @bunjavascript and @deno_land in @zeropsio. While setting up examples, I noticed more fullstack frameworks than backend ones (like @nestframework). Is the era of standalone APIs in JS really coming to an end? 🤔

What's your origin story?
At 14, I built my first website using Microsoft Frontpage, optimized for IE 4, on my parents' PC with dial-up internet. By 17, I landed my first job as a full-stack developer working with PHP Zend Framework and Mootools. At 23, I became a technical co-founder at costlocker.com, focusing on Angular.js frontend, design, and UX - my first real startup experience. Now at 33, I'm co-founding a developer-first cloud platform with its own incredible and bonkers origin story @zeropsio!
