Mendix shipped in a Docker container. Imagine… Imagine if you could setup a new Mendix. Hosting environment in seconds, everywhere. A lightweight, secure and isolated environment where you just have to talk to a RESTful API to deploy your MDA (Mendix Deployment Archive) and start your App. Since the 2nd quarter of this year a great piece of software became very popular to help to achieve this goal: Docker. Docker provides a high-level API on top of Linux Containers. Root@host: # docker run -d mendix/mend...

Category Archives: Collectd Graph Panel. Linux bcache SSD caching statistics using collectd. In October 2012 I started using bcache. As an SSD caching solution for my Debian Linux server. I’ve been very happy about it so far. Back then I used a manually compiled 3.2 Linux kernel based on the bcache-3.2 git branch provided by Kent. Which has been removed). This patch. Needed to be applied to make bcache work. I also created a Debian package. This is my setup:. Backing device – 20GB. This is the result:.

SSD caching using Linux and bcache. A couple of manufacturers are selling solutions to speed up your big HDD using a relative small SSD. There are techniques like:. SRT) by Intel (hardware solution, Write-back). By Nvelo (Windows, software, Write-back). By SanDisk (Windows, software, Writethrough). By Romex Software (Windows, software). But there is also a lot of development on the Linux front. There is Flashcache. Developed by Facebook, dm-cache. By VISA and bcache. A bcache patched kernel. I used the l...

Less CPU overhead with Qemu-KVM from Debian Wheezy | pommi.nethuis.nl
https://pommi.nethuis.nl/less-cpu-overhead-with-qemu-kvm-from-debian-wheezy
Less CPU overhead with Qemu-KVM from Debian Wheezy. An interesting thing happened last week when I upgraded qemu-kvm from version 0.12.5 (Debian Squeeze) to 1.1.2 (Debian Wheezy). After a reboot (shutdown and start) of all my VM’s, they are using less CPU in total! I noticed this from the stats Collectd is collecting for me. Looking a bit further I also noticed that the Local Timer Interrupts and Rescheduling Interrupts are halved. They’ve done a nice job at Qemu-KVM! This entry was posted in Know How.

Testing a D-Link Green Switch. Since a while I’ve been monitoring the power consumption of devices in my home using a power meter from BespaarBazaar.nl. This power meter is a good one because it is very precise. It starts measuring at 0.2 Watt. I needed an Ethernet switch to connect my TV,. And PS3 to my home network. While searching for a proper switch, I came across DLinkGreen.com. It looked promising. The Green Calculator. A 87MB Flash app which is using a lot of CPU. M = 100 Mbit, g = 1 Gbit. Leave a...

Bonnie to Google Chart. Is the perfect tool to benchmark disk I/O performance. When you want to run heavy disk I/O consuming applications on a server, you need to know what the disk I/O limits are to have an indication what you can run on it. Bonnie gives you information about read-, write-, rewrite Block I/O performance and the performance of file creation and deletion. I’ve developed a tool called bonnie2gchart.
