Hooking into the Windows Message Queue in UE4
I recently came across several community projects that try to process Windows messages by hacking the Engine’s message loop, but there is a better way. Earlier this year I added the IWindowsMessageHandler API, which does not require any Engine code changes and keeps your plug-in self-contained.
Install ArchLinux on BeagleBone Black
The installation of ArchLinux on ARM based embedded devices is well documented online, but I always forget the extra and optional steps that are assumed to be known.
ArchLinux iSCSI on BeagleBone Black
I recently hooked up a BeagleBone Black to an iSCSI target on a Synology NAS. The iscsi_tcp module is not being built in the legacy kernel by default. Newer versions of the kernel include it as a loadable module.
ArchLinux Internet Connection Sharing on BeagleBone Black
I have a BeagleBone Black connected directly to my desktop PC for development and testing. Occasionally, I need the BBB to connect to the internet, for example to download updated packages. This post describes how I am sharing the internet connection between the two computers.
ArchLinux AX88179 on BeagleBone Black
Last time I checked there was no built-in support for AX88179 chipsets in the ArchLinux kernel for BeagleBone Black yet. As these chips are now being used more widely in USB 3.0 adapters for gigabit ethernet, this post describes how to install the kernel driver manually.
ArchLinux Kernel Compilation on BeagleBone Black
I recently had to modify and recompile the kernels on my BBB’s. Cross-compilation is well documented on the internet, but what if you want to compile directly on the device? Here are the steps.
Restoring KDE Multiple Monitor Display Settings
When running multiple monitors on KDE, the current display settings may not be restored after reboot. Replacing xrandrmonitor with kscreen is one easy way to work around this.
25 Absolutely Stunning ArchVis Projects in UE4
A selection of architectural visualization projects released by UE4 users in the recent months.
SonicWall TZ 210: Access Public Server from within LAN and DMZ
This article describes how to setup a loop-back NAT policy that allows firewalled computers to access a server using the server’s public IP address or FQDN.
Implementing the abs() Function in Plain C/C++
This article describes how to calculate the absolute value of an integer without using any built-in functions in C or C++. The problem is based on an interview question that I used to ask candidates every once in a while, and it was not so much about coming up with an algorithm, but rather about understanding why the proposed algorithm works.
