I wanted to have the option to run a web-application on my local machine, and make it seem as if it is running as part of a collection of web-applications on a remote cluster. The collection of web-applications on the cluster make up the whole of a web-site, and during development you might want to “replace” one of the web-app’s by a version on your own machine, which is under development. Note: where this story mentions web-app or web-proxy, you…
TL;DR; See https://github.com/atkaper/oracle-forms-standalone-runner on how to download and run the forms viewer… If you want the background as to how I got there, read on… At the office, we still use a couple of old/legacy oracle-forms-11 applications. The “normal” (designated) users will run these from Windows, in the Edge browser switched to old Internet-Explorer compatibility mode… You can not start Oracle Forms Applets in any other browser or operating system, as applets are no longer supported. As I do run…
A good friend of mine (Milo) was featured last year on Hackaday with a post about building a circular LED clock. See Milo’s GitHub repository for the original code/version and build instructions. I did build his project, and added some more effects / animations / features. For this new extended version, see my GitHub repository: https://github.com/atkaper/LEDCircleClock . I did not 3d-print the proper case for the clock yet. For now I just put it in a picture frame, with a…
I thought that since working from home those last two years, it would be a nice gadget to have a toggle button to enable/disable the microphone when using MS-Teams for online video meetings. But a macro keypad with just one button is a bit silly, so I decided to go for 8 buttons. I did not really think too deep, and came to these functions for now: toggle microphone in ms-teams. toggle video in ms-teams. open a…
Introduction If you are running your pod (services / containers) on a Kubernetes cluster, and the pod runs into problems, you can decide to take it out of the load, but keep the pod running for further investigations. TL;DR; See the notes section on this site for the short summary; Note: Kubernetes Isolate Crashed Pod Kubernetes Recap Lets start with a summary of the Kubernetes components which are involved, here is a small (simplified) recap of how the parts fit…
Description Enable special functions on the CAPS-LOCK key, to support VI users 😉 This script was created by me as a sort of “study” object, not for any serious use. A colleague of mine has created a Linux kernel module to modify his keyboard behaviour to what is described in this document. I was just wondering if it would be possible to create the complex logic he needed, without having to make a kernel module. As maintaining a kernel module…
See also GitHub: https://github.com/atkaper/htmlcoder-go Intro We want to try using GoLang for some micro services at the office, so a bit of Go study was needed for me. This article shows some of the references I used to start using Go, and it has my first bit of Go code. In the last weeks, I had to decode some html entities, and used an online html decoder web form for this. So I chose to make this html decode into…
Suppose you have a kubernetes cluster, which contains a large set of ingress rules, of which many are used for the same hostname (just using different context-root’s / paths). In this case it can be hard to find out which rule is used for a certain URL. To help out in this situation I have created a Linux script to make a nice overview of paths mapped to what services by which ingress rules. You still have to read through…
The web-gui on a synology NAS has an application called “Universal Search”. I wanted to be able to use this from the shell command line on the NAS also to find my files, so I set out to find if that would be possible. TL;DR; See https://github.com/atkaper/synology-universal-search-cli for the end result. Or scroll down almost half way, till you find first mention of “synowebapi”. To use Universal Search, you first have to set it up using the web-gui, to index…
My brother needed an old telephone handset to be connected to an audio amplifier, to use as microphone for his band. They were aiming for this old (fuzzy) telephone sound to use in one of their songs. After a bit of searching, I came across some instructables (see references at bottom of page), and combined and simplified them a bit, and put the stuff together. Parts list: XLR Male Connector, to connect to a “real” audio microphone cable. Small 600…
