- Simple Docker GUI for monitoring and managing containers and images – in combination with Vagrant and VirtualBox
I came across a simple Google Chrome Addon called Simple Docker GUI. It provide a GUI that allows for easy insight in and some management of Docker containers and images. Because the tool connects to the (remote) Docker API across HTTP, it can used on a different machine than the one running the Docker Engine. […]

- Index Usage – 2
I’ve beeen a little slow in the follow-up to my previous posting on possibly redundant indexes. Before going into the slightly more complex stuff, there’s another peripheral point (but a very important one) that’s worth raising about how clever the optimizer can be.

- Switch Panes in Page Designer
This is definitely worth of mentioning. Go here and download this plugin for Firefox or Chrome. You will like it. It switches the panes in the Page Designer so you can much easier access the properties of the selected elements. Congrats Filip. This is a cool feature. Thanks.
- Vagrant, Docker, VirtualBox and the Graphical Desktop for GUI applications in Docker Containers
Although perhaps not a common occurrence, I would still like to be able to sometimes run GUI applications inside a Docker container. This may be required because an installer does not provide a silent option and has a GUI wizard I need to click my way through in order to set up the software that […]
- Three Easy Ways to Stream Twitter Data into ElasticSearch
For the past few months a friend has been driving me crazy with all his praise for Splunk. He was going on about how easy it is to install, integrate different sources and build reports. I eventually started playing around to see if it could be used for a personal project I’m working on. In […]
- Creating a Trace File from EM12
Creating a trace file from EM12c is quite easy and doesn’t require a DBA offering up the world to allow a developer or support person to perform this action. Enterprise Manager also removes some of the syntax options that could get a developer or app support person that is less specialized in creating trace files, all […]
- Amazon Dash — It’s Dinner Time!
Yesterday I received an Amazon Dash for ordering IZZE juice. I think it is a great device, not that I would order tons of IZZE from Amazon, but at $5 it has wifi module + a micro controller + a LED light + a battery + nice enclosure, and it’s usually in deep sleep which […]

This is common practice, for example with the (bash) shell. Colors can also be very useful to improve the quality of the output of […]
- amcmd> a better “du”
I discovered ASM with a 10.1.0.3 RAC running on Linux Itanium and that was a big adventure. At this time there was no asmcmd. In 2005, Oracle released Oracle 10gR2 and asmcmd came into the place and we figured out how to make it work with a 10gR1 ASM. We were very excited to have a […]
