Problem installing Nokia Maps 3 on N82

I was getting error message from Nokia Map Updater, that compatible phone is not found, until I tried to run old version of Nokia Maps (2.x which comes in v31 of firmware) for the first time. After it has started and created some registry settings and own files on the phone, Nokia Map Updater immediately found my handset and proceeded with installation of Nokia Maps 3.

Windows 7 x64 Ramdisk

image

Since the beginning of times, I speed up Firefox on all my computers by putting its cache on a ramdisk. Only recently I started to use Windows x64 and faced with the problem that it is impossible to start any free ramdisk under W7 x64. Luckily, there was a solution on on sevenforums.

Download the Ramdisk from
CENATEK: High Speed Storage Systems
Select the 1st one on the top (Public Beta V.3.5.107) and save the msi file to c:\
Don't start the MSI, it will not work.
Decompress the MSI-File (Start/Run CMD as Administrator):
msiexec /a Dataram_RAMDisk_v3.5.107.msi /qn TARGETDIR=C:\Driver

Since we have no "add hardware" in control panel, we have to install this driver manually.
The Hardware-Wizard still exist.
Start/Search -> hdwwiz.exe
- Button "next"
- select "hardware manually (expert)"
- Button "next"

- select "All Devices"
- Button "next"
Now you have to search for the Button "have disk". Click on this button and search for the folder
C:\Driver\Program Files(x86)\Ramdisk

select RAMDiskVE.inf
- Button "OK"
- Button "next"
- Button "next"
To Configure the Ramdisk start the program
C:\Driver\Program Files(x86)\RamdiskVE.exe

For me (solnyshok) RamdiskVE reports failure to start ramdisk, but after rebooting the computer, ramdisk with the required parameters is there. So, don’t panic if you get this error.

The 2nd part is easy and described in detail here. Requires creating a string browser.cache.disk.parent_directory containing the path to new cache location.

CoLinux Ubuntu 9.04

image

Yesterday I played with CoLinux on my laptop with Vista x32. Tried it first with Windows 7 x64 but turns out that CoLinux is only available for x32 bit environments. Anyway, it started find with Vista x32 and I even upgraded the original image (Ubuntu 8.04) in two steps to 8.10 and then to 9.4. Had to increase image size from 1.7GB to 8GB. Increasing image size involves creating a new empty image file under windows, then mounting it under CoLinux and copying all information to it, quitting CoLinux and restarting with new image file. Instructions are in the Colinux FAQ section. Maybe 8GB is an overkill, and 4GB would have been enough, but I made it bigger just in case I will want to install more programs.

It works great, faster than virtual machine. Internet works, but I still have to figure out how to see local network.

Dual core Atom based home server

20090501074

Here we go, the small box based on Dual Core Atom 330 with total consumption around 50W replacing a 150W old Pentium 4 tower. It used to be around 35C in my wardrobe, now we are back to silent operation and normal room temperature. As I mentioned before, I have there 1TB 3.5” drive mostly idle 95% of the time and 500GB 2.5” laptop hard drive for 24*7 torrents.

And I am using W7 x64 build 7100 (RC) with it. I tried Home Server 2008 R2, Ubuntu 904, FreeNAS. I believe that W7 beta is so far the best value proposition, as it is very stable, versatile and free till the June, 2010.
