I have just finished my masters at Aalborg University with a degree in Software Engineering.

I forgot to change the SMTP server when moving my website to its new location. This means that I have been unable to receive e-mail from people, through this site. This is now fixed

I have just bought a ThinkPad W510 as I am in need of a laptop with discrete graphics, supporting CUDA, OpenCL and DirectCompute. My previous laptop, the HP 8530p, featured an ATI 3650 Radeon card which is sufficient for BrookGPU development, but not OpenCL or CUDA development.

Anyhow, the specs of my recent purchase are:

• Full HD (1920x1080) 15.6” 16/9 panel
• Quad Core i7 720QM – 1.6GHz (2.8GHz turbo)
• 4GB DDR3
• nVidia Quadro FX 880m supporting CUDA 1.2 and OpenCL 1.0 (1.1 should be comming)
• 320GB 7200 rpms (I have replaced this with my Momentus XT)
• 9 Cell battery (max 3½ hour battery life at 10/15 light setting and Wi-Fi on)

I am very happy with the laptop, the keyboard is phenomenal, the screen is 95% gamut and looks great (although I would have preferred a 16/10 instead of 16/9), the temperatures are around the 50-65c with very low fan noise (compared to my HP), and the build quality is excellent!

The only problems I have experienced are minor coil whine from the CPU and problems with resuming from sleep.

Coil Whine

Coil whine from the CPU can be 100% eliminated by disabling CPU power management in the BIOS with a 35% cost in battery life. However, one can instead disable “deep sleep” in Lenovo's power manager, which reduces the coil whine substantially and with only minor decrease in battery life (5-10% is my guess).

But!!! as of this writing, the coil whine has nearly disappeared and can in many circumstances not even be heard! I don’t know why my W510 has ceased “whining”, but it might be due to my over clocking attempt of the GPU (this is the only thing I can think of).

When utilizing Bluetooth, the coil whine can sometimes reappear, although I have yet to investigate this further.

Resume Troubles

Another annoying problem I’ve been experiencing is problems with resuming my laptop from sleep. 90% of times it works correctly, but sometimes the W510 won’t resume and it just blinks at 3-4s intervals, very strange. When this happens I have to do a hard reset and remove the optical disc drive. If I don’t remove the optical disc drive, resuming will fail next time I put the laptop to sleep; so it might be a problem with the UltraBay.

Anyway, I am a happy ThinkPad W510 owner!

Finally, 8th semester of my Software Engineering study is over and I can look forward to two months of "Vacation", except that I will be working at SKOV for roughly 6 weeks. Anyhow, I just had 5 days of vacation where I decided to update the look of my website as you can see. 

I created the theme based upon  different icons and graphical stuff that I could find on the Internet. The theme is not 100% complete yet, I still need to fix the smilies (they were made for a white background and look terrible on my darkish background).

Anyway, I am very satisfied with the current look and I intend to release the theme when I am done. 

News Theme

I have just ordered a new server for my website (and other stuff that needs hosting)

The server will feature a ITX motherboard, specifically, the D510 NM10 from ASUS. The D510 comes with a dual-core ATOM processor which should be enough for my needs.

For storage, I have ordered 2x 250GB Samsung 2.5 inch hard drives. I intend to use Windows 7's raid feature and mirror the drives to increase the reliability of the server. I have also ordered an external 250GB Samsung disk that will be used primarily for backup purposes. I intend to perform automatic daily and weekly backups to this disk.

Also, I intend to order a 1TB NAS drive to store all my non-essential stuff, and, as a secondary backup solution. However, I have yet to find the right NAS drive for my purposes, any recommendations?

Last but not least, I have ordered an Antec Skeleton case (for ITX), which is and open case (plenty of air) and features a 150mm fan and should be pretty noiseless.

I should receive all my "stuff" in about 10-14 days.

News server, asus, NAS, backup

My web server crashed yesterday, the hard drive died, and I have pretty much lost everything from my old website. Therefore, I've decided to rebuild my website on a new, and hopefully, more reliable web server.

I have only managed to save around 10% of my old projects and have therefore lost alot of work. However, I intend to create a "R.I.P" section with the projects that have been lost in the hard disk crash.

Anyway, I have decided to use BlogEngine.NET as the base for my new website as it appears to be a very flexible solution.

The blog is currently hosted on my Media Center, so don't expect 100% uptime.
