Peek makes it easy to create short screencasts of a screen area. It was built for the specific use case of recording screen areas, e.g. for easily showing UI features of your own apps or for showing a bug in bug reports. With Peek, you simply place the Peek window over the area you want to record and press "Record". Peek is optimized for generating animated GIFs, but you can also directly record to WebM or MP4 if you prefer.
Headlamp is an easy-to-use and extensible Kubernetes web UI. Headlamp was created to be a Kubernetes web UI that has the traditional functionality of other web UIs/dashboards available (i.e. to list and view resources) as well as other features.
Legend builds and publishes Grafana dashboards for your services with prefilled metrics and alerts for your services. Say you got an EC2 to monitor, an S3 to monitor, a Kubernetes cronjob to monitor (or one of many other things); legend has got your back. It will do all the menial work of setting up grafana dashboards for you without you needing to setup grafana dashboards manually or write cloudwatch/prometheus/influxdb queries by hand.
Here’s the thing: I write open source software to solve my problem. I let you use my solutions because that comes at zero cost for me (well, almost, I still have to pay for the website, you are downloading from. You are welcome, by the way).
Normally I only pay attention to leap seconds every 6 months when the IERS publishes Bulletin C, the leap second yes or no announcement. But this week brings news from Michael Deckers via the LEAPSECS mailing list, and it relates to Bulletin A, which is why it’s off my usual 6 month schedule.
I went into my office yesterday for the first time in a few months to pick some stuff up. We got notified a couple of days ago to get any personal property out of the office before Thanksgiving or else it'd be thrown out, so I guess we're moving out of the office1. It was a pretty eerie place to be; even now, 8 months later, most people haven't been back and it kind of looks like the entire office was abducted by aliens in early March.
Most PCs tend to boot from a primary media storage, be it a hard disk drive, or a solid-state drive, perhaps from a network, or – if all else fails – the USB stick or the boot DVD comes to the rescue… Fun, eh? Boring! Why don’t we try to boot from a record player for a change?

We created the Fleet Project to provide centralized GitOps-style management of a large number of Kubernetes clusters. A key design goal of Fleet is to be able to manage 1 million geographically distributed clusters. When we architected Fleet, we wanted to use a standard Kubernetes controller architecture. This meant in order to scale, we needed to prove we could scale Kubernetes much farther than we ever had. In this blog, I will cover Fleet’s architecture, the method we used to test scale and our findings.
If you ever connected to the Internet before the 2000s, you probably remember that it made a peculiar sound. But despite becoming so familiar, it remained a mystery for most of us. What do these sounds mean?
illuminatio is a tool for automatically testing kubernetes network policies. Simply execute illuminatio clean run and illuminatio will scan your kubernetes cluster for network policies, build test cases accordingly and execute them to determine if the policies are in effect.
In this article, I'll discuss 5 very confusing mistakes that have caused me to waste significant amounts of time when using the command-line tool known as 'grep' to search for things. I have chosen to document these mistakes in detail because they are mistakes that beginners are very likely to make at some point, but also to not be able to debug on their own. The root causes of these mistakes are: Not knowing what flavour of regular expression that grep is currently using (and/or not understanding what features that flavour supports); Not considering the escaping rules of your shell; Issues with character encodings.
The scp command, which uses the SSH protocol to copy files between machines, is deeply wired into the fingers of many Linux users and developers — doubly so for those of us who still think of it as a more secure replacement for rcp. Many users may be surprised to learn, though, that the resemblance to rcp goes beyond the name; much of the underlying protocol is the same as well. That protocol is showing its age, and the OpenSSH community has considered it deprecated for a while. Replacing scp in a way that keeps users happy may not be an easy task, though.
Every now and then I get questions on how to work with git in a smooth way when developing, bug-fixing or extending curl – or how I do it. After all, I work on open source full time which means I have very frequent interactions with git (and GitHub). Simply put, I work with git all day long. Ordinary days, I issue git commands several hundred times. I have a very simple approach and way of working with git in curl. This is how it works.
