MacOS – RAW to/from EWF Image Conversion
The old (and free) FTI Imager command line tool still is one of my favourite RAW to/from EWF (E01) conversion tool in MacOS. Most tutorials point to ewf-tools, but in case of problems, the good ol’ ftkimager can come to the rescue.

Scraping a GIThub repository into DEVONthink using AppleScript
Sometimes, the easiest way to keep a small GIThub repository for later study is to safe it into a document instead of cloning everything into an abyssal directory structure. Clipping into DEVONthink makes the project searchable as well and part of your knowledge base – Thank is amazingly handy to find it back later :)
The ever-hanging AppleScript Editor
The (My) AppleScript Editor tool, version El Capitan, has the bad habit to hang itself from time to time. Regular saving and killing the blocked process, followed by a simple restart of the tool was generally a good way to mitigate the problem. Once, however it was not possible to cleanly restart the AppleScript Editor even after a reboot…
Convert a Parallels Virtual Machine to VirtualBox
As user of the recent version of Parallels Desktop 12, you might be looking for the famous “Parallels Image Tool”.

Bridging VPN to Local Network with a Linux VirtualBox Proxy
A Linux (VirtualBox) VM connects to a VPN and this connection should be usable by the host machine (that runs the VM) or other machines on the local network for that matter. For security reasons, the Linux VM should not be a full member on the local network, which means that it cannot reach anything and cannot be reached on the LAN. This article discusses how to set-up a VM for that case.

Modal JaxaFX Progress Indicator running in Background
There are times when one just wishes to magically pop-up a modal progress indicator while doing some hard work in the application’s background.

This post just explains how to do this…

Monero – How to Setup a Full Node under Linux
Monero is a crypto currency in the same way than Bitcoin is. Monero is however extremely different in many ways. It has different goals and does not share software and code with the Bitcoin code. Due to the decentralized and peer-to-peer nature of the Monero network, it becomes more robust and resilient as it becomes larger. Running a full node helps stabilizing and securing the network. A full node contributes to the consensus and increases the Blockchain data distribution. So…let’s set-up one…

DEVOXX on Security
We, the DEVOXX 2015 Security track team, want to increase security awareness among software and hardware developers. We want to make this year’s track about understanding how to break things, and knowing that this understanding allows developers to design and build more secure systems. Security has to be by design, not by feature, use case or layer. In this spirit, we would like to invite you to submit talks around the subjects on how to stress security of software projects and on how to deal with these aspects as a developer and architect. Any submission of topic ideas is very welcome too.
