Earlier this year, I recorded a three-episode series, «Streaming on Kubernetes: It doesn’t have to be the hard way.» There I showed some demos of the Confluent Operator on Kubernetes. Many people reached out after and asked - «What kind of terminal do you use,» «What kind of plugins do you use» and so far and so on. And today, I’m going to be talking about five Kubernetes tools that I use in my demos (of during preparations to it) that you’re probably don’t use but defiantly should.

Wed, 28 Nov 2018 00:00:00 +0000

A very small tip for you!

TLDR

the Sole purpose of this post is to help me to return here time to time if I forget some of the commands. If this would be useful for anyone - praise me on twitter - http://twitter.com/gamussa.

Let’s start with small but important thing - how to erase everything Docker and start clean.

Delete every Docker containers

Don’t do this if you’re on the plane. Downloading new images using airline’s wifi will be the pain. Proceed with caution. You have been warned.

Alfred Extension: Show/Hide desktop icons on Mac OS X

Mon, 21 May 2012 00:00:00 +0000

For some reasons, I’m using desktop as temporary storage of files - downloaded from internet, in-progress documents, screenshots and code snippets. Time after time I create screencasts and I need to have clean desktop. First, I tried to find available solution and have found Desktop Curtain. I don’t need all this fanciness (different desktop wallpapers, customization) so $2.99 is overkill for me and for this taks. So, I decide to create my own solution with help of shell and Alfred. Googled for Mac OS X command and I created simple script what I wrapped after as Alfred Extension. You can download Alfred Extension for my Dropbox. To use it you need to have Alfred PowerPack purchased. Cheers

How to download videos from InfoQ for offline viewing

Sat, 28 Jan 2012 00:00:00 +0000

From my humble opinion, InfoQ is one of best resources for developers nowadays. You can find lot of IT related stuff - interviews, articles, presentations slides and videos. And today I would like to talk about videos from InfoQ in particular. Is always good to have offline version to watch it during long commute, for instance. Unfortunately, InfoQ administration for some reasons not allow to download videos.
However, I found very elegant solution how to do that. I did it on my MacOS X with Safari, probably it will work with Safari for Windows as well.

Mac OS X shipped with 2 versions of JVM - 32 bit and 64 bit accordingly. So, First I tried to change order of JVM preference from /Application/Utilities/Java Preferences but it didn’t work.
