Where does uTorrent keep its .torrent files?

NOTE: uTorrent installs a bitcoin miner and probably logs all torrents you download with it. Don't use uTorrent! I recommend using Tixati for all your torrent needs.

If you deleted uTorrent and want to remove all of its files, you might want to know where it stores them.

On Windows 7, uTorrent stores .torrent files by default in:

...where %USERNAME% is your Win7 username, and assuming your Windows 7 installation is on C: drive.

If you can't browse to this directory, write it on the address bar of Explorer. Another way is to show hidden files by going to Win7 control panel's "folder options" - then you can see the AppData folder.

Installing Worms Armageddon on Windows 7

Here's how:

1) Put the CD in your CD Tray
2) Download and run this installer
Be sure not to use spaces in the directory name.

For me, the installer didn't install the patch and the update.
Download them and install first the newest patch, then the update.
I recommend getting the newest beta version.

Worms Armageddon is still being updated to this day, which is quite incredible...

Upgrading Ubuntu Server 11.10 to 12.04 LTS

Here's how I updated my server's Ubuntu from 11.10 to 12.04 LTS.

I don't have a desktop installed on the server, so I had to run the upgrade from terminal. I have a forum running, a lot of MySQL databases and Apache 2 on the server. I'm also running sensord and other stuff like that. So some of the software will probably need some configuration.

I logged on my server as root and ran
apt-get update
apt-get upgrade

I installed all the updates, except new versions of the kernel. Maybe it's even better if you run
apt-get dist-upgrade
... which will install a new kernel version.

Then, using nano I edited the /etc/update-manager/release-upgrades file:
nano /etc/update-manager/release-upgrades

I changed it to read:

Then the update can be started:

You might need to install the update manager first:
apt-get install update-manager-core

So the install started running, and quickly I was asked if I wanted to change the MySQL database root password. I chose not to, by leaving the field blank. This will keep the old password. Somehow, I was asked again for this two times...

Then I was asked if I want to be prompted when services are restarted during the upgrade. I chose not to, to make the upgrade process faster.

Then another question about the MySQL server password. I'm starting to think I should have set one in the first place... How times will it still ask me?

Then came a question about sensors3.conf. The file has been modified but a new version is available. After checking the differences between the files, I chose to take the new version. There was no important changes in the file.

Fifth MySQL root password question... Left it blank again.

Then a more important question. "A new version of configuration fiel /etc/php5/apache2/php.ini is available, but the version installed currently has been locally modified. What do you want to do about modified configuration file php.ini?"
There was an option to see what changes had been made to the file in the new version and on my local version. I had set the post_max_size and upload_max_filesize to bigger values. Since there were many changes to the php.ini in the updated version, I chose to take that one and just do my custom changes again.

Next question: "Remove obsolete packages? 33 packages are going to be removed." I checked the packages and none seemed important - newer versions were probably already installed.

Finally, the upgrade was complete. After a reboot, the system was running 12.04. BUT, only SSH was usable. Somehow the display adapter was just blinking a gray picture on my screen... Oh, well. Luckily, I didn't even need the display adapter - I just removed it and switched to using the integrated adapter of the server PC. That one worked fine, so why bother trying to get the other one working.

So, there's my experience of upgrading to 12.04 LTS. Some problems, but the end result is what matters: the server is now upgraded and working fine!

Intel HD Graphics problem "Display driver stopped responding and has recovered"

I solved a problem with my Lenovo T410 Thinkpad.

The machine often crashed when viewing HD video. Black parts appeared on the screen or the whole screen would go black, and the computer would go to a halt. Sometimes Windows 7 gave an error message: "Display driver stopped responding and has recovered". But the system was always in a halt and showing no signs of recovering. This was clearly a problem with the Intel HD Graphics adapter.

I updated the graphics driver with Lenovo ThinkVantage Tools, using the Lenovo ThinkVantage System Update. However, the update did not solve the problem for me.

After getting frustrated for a while, I found that Intel has a newer version of the driver on their site. You need to use Microsoft Internet Explorer to open this URL:

The website will aid you in updating your Intel drivers. Unfortunately you need to install some browser add-ins to get it to work, but it pays off in the end. I also got newer versions of the wireless and wired LAN adapter drivers, which also have been crashing now and then on my computer.

It's a shame that Lenovo doesn't apply these critical updates with their own ThinkVantage System Update software... Maybe some day.

Get Nokia E90 Maps working with the old Map Loader and PC Suite

I wanted to update my E90 and get some maps for my old Nokia E90 Communicator, but the new Nokia Suite program doesn't support E90 anymore. Nokia Suite just kept telling me that the device isn't connected.

I contacted Nokia and they let me know that the old Nokia PC Suite (different from Nokia Suite!) might work. You can still download Nokia PC Suite from Nokia website.

Well, after removing Nokia Suite and installing Nokia PC Suite, I finally got the Communicator linked to my PC. But unfortunately it doesn't work very well. Map download doesn't work but just throws you to Nokia Maps website. And the phone updater starts an install that never finishes :(

But at least I could now install some software on the phone and download images and recordings from it.

I started searching for a solution to the map loading problem and found a download link for Nokia Map Loader on CNET. After all this failing support for E90, I was surprised to find out that it actually still works!
With both the Map Loader and PC Suite running, I was able to select and download maps from the internet to the phone and they worked perfectly.

Removing Alureon.A / Backdoor.Tidserv!kmem

A friend had a nasty virus on his Windows XP computer. His Symantec endpoint protection software continually notified that a virus was found but not removed. In the Symantec program the virus was called "Backdoor.Tidserv!kmem".

First, I wanted to make sure that his XP was up-to-date. Updating Windows is important to make sure all known security holes are patched up. That makes it harder for viruses to get in the system in the first place. Unfortunately, the whole update system was disabled by the virus! Microsoft update and windows update webpages did not work on Internet Explorer, and you cannot use other browsers on those sites.

What I did first was to try to fix the update system by manually installing the Microsoft Windows update agent.  That did not work, and the windows did still not update with the virus in it.

Then I tried to manually install the Windows Malicious Software Removal Tool, and to remove the virus with it. Normally the removal tool is installed with the updates automatically, but now the virus was blocking that route, so that's why I had to install it manually. After running a quick scan with it and finding the virus (Alureon.A), I found that even the Malicious Software removal tool cannot remove this nasty virus.

By the way, If you ever want to run the Malicious Software Removal Tool again, you can just go to Start menu and click "Run...", and then write "mrt" and press enter. This will start the removal tool for you.

Back to the virus removal. By googling Alureon.A I finally found a cure. This Rootkit removal tool by Kaspersky (download link) removed the virus finally. Kaspersky's webpage for the tool is here. Symantec gave few virus warnings as the Kaspersky tool was running, but it didn't interfere with the removal. After booting the computer, also the windows update system was functional again!

Now the first thing to do was to update the XP to the newest version by going to the Microsoft Update webpage with Internet Explorer, and installing all the Express updates.

Finally the computer was free of viruses, and patched against the newest security holes. Always remember to update Windows and your web browser regularly to avoid virus infections!

iPod Nano blank screen fix

OK, this is not a PC tip, but whatever... Might help someone. A friend's iPod Nano 4th generation (A1258) went "dead". The thing didn't power on anymore and the screen was just blank. This happened after the Mac it was connected to ran out of battery juice.

The solution I found in the iPod Nano 4th gen. manual was simple: you have to reset the Nano. To do this, switch the hold switch (on top of the Nano) on and off and then quickly press menu and center buttons together and hold them for some 6 seconds.

This resets the Nano and it should run again fine!
