Unlock the Power of GPUs in Kubernetes for AI Workloads
Here’s a question. Where do we run AI models? Everyone knows the answer to that one. We run them in servers with GPUs. GPUs are much more efficient at processing AI models or, to be more precise, at inference.
Here’s another question. How do we manage models across those servers? The answer to that question is… Kubernetes.
The Future of Shells with Nushell! Shell + Data + Programming Language
Implementation and maintenance of terminal is tedious, especially when runtime portion of it is concerned. For example, if we’d like to be notified when a potential breach is happening, we’ll likely use a tool like Falco. It’s a great tool. It’s potentially one of the best if not the best tool of it’s kind. It allows us to define an infinite number of rules that, when one of them is met, will fire notifications. That’s the problem though. We have to define all those rules or, at least, accept a significant number of rules that are available out of the box. Essentially, we need to predict everything that should not be allowed to happen or, if we prefer the other way around, everything that is allowed. That is tedious and you are likely going to end up frustrated at best, in an asylum at worst. After all, who can predict all the bad things that might happen? and who is fully aware of all high and low level calls that applications are making? I certainly can’t.

Stop Losing Requests! Learn Graceful Shutdown Techniques
Look at this.
I will send a request to the application,…
curl "http://silly-demo.127.0.0.1.nip.io/fibonacci?number=50"…and simulate failure or upgrade or any similar action by deleting the Pod where the application is running.
kubectl --namespace a-team delete pod \
--selector app.kubernetes.io/name=silly-demoThe output of the curl command is as follows.
<html>
<head><title>502 Bad Gateway</title></head>
<body>
<center><h1>502 Bad Gateway</h1></center>
<hr><center>nginx</center>
</body>
</html>Since we initiated the delete process before the server returned a response we got 502 Bad Gateway message. The application was deleted before it could respond and I, the user of that application, failed to get what I was looking for. That’s horrible experience that could have been improved by enabling the application to shut down gracefully.
Surviving Backstage with Roadie: A Developer’s Nightmare or Dream?
Today I want to talk about potentially the most important tool in your toolbox. I want to talk about a tool that might enable everyone in your organization to be more productive and self-sufficient. Yet, the tool I want to talk about might win an award for the least user-friendly, hardest to maintain, and, generally speaking, a tool that might cause you to have nightmares and spend a small fortune on a psychologist.
It’s a tool that I recognize as being one of the most impactful tools which, honestly, I do not like at all, yet most of those who use it swear by it.
Did you guess what that tool is?
Master Terminal Multiplexing with Zellij in Minutes!
Let me show you something exciting, something that makes me much more productive.
I am going to execute command zellij, specify a name of the session (crossplane-kubernetes), and a layout (test-layout.kdl), and…
zellij --session crossplane-kubernetes --layout test-layout.kdlBOOM!
There’s everything I need, nicely split into tabs and panes.
