If you are working with virtual machines for testing and development purposes often, it might be comfy not to have to login manually after each reboot. So for those circumstances you can use a somewhat hidden feature to automatically login.
We strongly recommend not to do this on your working machine where you store all your sensitive information. Continue reading →
Tom’s Hardware tested Steam for the Mac intensively. Their first impressions are disappointing for Apple fans: the Windows version of Steam is a lot faster.
As their benchmark test they used the Valve’s game “Portal” and took benchmarks from two computers:
1. A mid 2009 Mac Book Pro
2. A custom built Hackintosh
Right, they’ve set up a hackintosh with all its ingrediences. Check their tables: you can clearly see the framerates are a lot higher on a Windows installation, but on a Hackintosh system the Mac OS version of Portal becomes playable after all.
So what do we learn?
First: Valve’s step to get on to the Mac OS platform is a good one. But they still have lots of work to do. Second: playing on Windows means more fluent gaming as the framerates are a lot higher (around factor 2). Third: if you’re willing to play on Mac OS you may consider setting up a hackintosh. A hackintosh with the config above easily outpaces at a normal Mac Book and it costs only about half the money.

VirtualBox is an open source virtualization software. Originally it has been developed by a german company named Innotek, which has been acquired by SUN Microsystems in 2008. SUN Microsystems in turn has been acquired by ORACLE in 2010.
Innotek originally collaborated with Connectix on Virtual PC – a virtualization software targeting the Mac OS platform. Connectix has been bought by Microsoft in 2003. Innotek then decided to develop VirtualBox.
VirtualBox is used by many companies for virtualization and thus developing. Palm for example uses VirtualBox for WebOS development in an emulated environment. Thus allowing either Linux, Mac OS or Windows host systems for development.
CPU VT-X/AMD-V Issue
After configuring a dual core virtual machine and trying to start you may encounter a message box indicating:
This issue may occur no matter which host operating system you’re using. The reason for this might be:
you’re not using a CPU that supports hardware virtualization
your BIOS does not support hardware virtualization properly
hardware virtualization is disabled in your BIOS settings (check it!)
there is a bug in your current BIOS version regarding
Disable USB for the virtual machine
Reduce the amount of CPU cores to 1
upgrade your BIOS to the latest version (this might be dangerous)
Disable 3D acceleration
Shutdown your host machine, unplug (!) from electricity for say 30 secs, reboot then
As we’re currently using VirtualBox only on the Windows XP platform we categorized this article under Win, anyway it is very likely that the same issue also occurs under Linux or Mac OS, as VirtualBox on all platforms derives from the same source code.
Any suggestions, hints or things need to be added? Don’t hesitate to tell us below…
Have you also been trying to find a really nice screensaver for your Windows machine. There are so many nice screensavers for the Mac, but for the Windows world you can’t find them.
What we found
While searching for nice screensavers we came accross this collection of free of charge and open source screensavers called “Really Slick Screensavers”. Check them out. The screensavers included are named:
TrueCrypt is the leading open-source software to encrypt drive volumes. It supports Windows, MacOS X, and Linux. Version 5.1 has been released just 3.5 months ago in march. Now the Truecrypt team has released version 6.0 with the following features:
Parallelized encryption/decryption on multi-core/multi-cpu systems – thus demanding less time for the en- and decryption operations
Windows Vista, XP, 2003, 2008: run encrypted operating systems from hidden volumes (!)
Windows Vista, 2008: encrypt whole drives (incl. extended/logical partitions)
MacOS X: Create hidden volumes
Anyway: Permanent decryption has been removed from TrueCrypt’s bootloader, in order to support hidden operating system volumes. Permanent decryption now has to be done using the boot disk.
