It's been a few years since I was a maintainer of minikube, but after the news that Docker Desktop will no longer be free for enterprises and some of the misconceptions of how the technology works, I thought I'd write...
Last December, I was invited to a private bug bounty program to test a beta version of GitHub Actions. GitHub Actions is a workflow automation tool integrated with GitHub. One common use case of GitHub Actions is for CI builds – a project can fairly easily start up a Docker container every time they push a commit…
An update on using .NET and containers together, learn how to tackle staying safe and keeping your container images up-to-date.
Suppose you need to create a function for adding two numbers together in plain C. How would you write it? What sort of an API would it have?...
I suggest that serverless computing, or “serverless” has hype that at this point has outpaced what the technology / philosophy / religion has been
The Rocky Enterprise Software Foundation (RESF) is pleased to announce the availability of the Rocky Linux 8.4 Release Candidate for: ...
Kubernetes is a big and complicated technology and it clearly requires some time and dedication to wrap your head around. There is no vendor lock-in…
Building resilience teams with chaos engineering principles.
Artwork courtesy of the Jenkins project. At Slack we manage a sophisticated Jenkins infrastructure to continuously build and test our mobile apps before release. We have hundreds of jobs running in a variety of different environments. One day something very odd happened — our Jenkins UI stopped working although the…
If you're building an application that needs to scale—and we all tell ourselves that we are—then at some point you have to figure out if it does or not. This is where load testing comes in: if you want to see whether or not your application can handle scale, just generate scale and see if it can handle it! It sounds…
Docker announces significant upgrades to its subscription plans, delivering more value, flexibility, and tools for customers of all sizes.
Putting your IT infrastructure into the cloud seems to be the "in" thing. It's been around for a while, of course. And, like most things rel...
It all started with the big bang! We nearly lost 33 of 36 disks on a Proxmox / Ceph Cluster; this is the story of how we recovered them.
We provide a technical analysis of a container abuse attack that features a payload that’s specifically crafted to be able to escape privileged Docker containers.
To streamline the productivity of the JFrog Platform we will be sunsetting Bintray (including JCenter), GoCenter, and ChartCenter services on May 1st, 2021.
Dropbox, to our customers, needs to be a reliable and responsive service. As a company, we’ve had to scale constantly since our start, today serving more than 700M registered users in every time zone on the planet who generate at least 300,000 requests per second. Systems that worked great for a startup hadn’t scaled…
TL;DR: Some Linux distros and even different kernel versions within a distro have disabled IRQ time accounting. In such case, your monitoring tools will report zero time spent in hardware interrupt handlers (shown as %hi, %irq, hiq, etc). It’s easy to check how your kernel is behaving by looking at /proc/stat and you…
We compare NGINX performance in bare-metal and virtualized (hypervisor) environments, finding a small but measurable performance cost for hypervisors. We also find that performance in Kubernetes environments is worse for network-bound but not CPU-bound operations.
While I've made engineers inside Amazon aware of all of these at various times, I think it's time to post my wishlist here — both so that a wider audience inside Amazon can hear more about these, and so that the FreeBSD community (especially the people who are financially supporting my work ) can see what I'm aiming…
Yes, hiding HTTP-referers on your outgoing links are still a thing. Even though standards evolved, they rely on your user having a current browser, which is really something outside of your control. Even then, many larger websites have technologies in place to mask the http-referer on outgoing links. This is to avoid…
UPDATE 2025-05-19 Somewhat un-suprisingly AWS has closed the loophole that I was exploiting for this https://aws.amazon.com/service-terms/#30._AWS_Lambda and as such compiling data into your lambda …
