Most notable issue is that Network Manager will just fail to connect to the bluetooth access point immediately. If you install blueman, a great bluetooth manager, you will get the message “Connection refused (111)” or something similar which is a little more helpful, but not quite. To fix this, follow these steps.

1. Turn on tethering, on your iPhone click Settings > General > Network and turn on Internet Tethering. Tethering seems to be turned off by default on the iPhone.
2. Make sure that you delete all pairing with your iPhone in the bluetooth-manager (right click and go to preferences)
3. In your iPhone, go to Settings > General > Bluetooth, slide the computer paired connection, to the left and “Forget this Device”
4. Hold down the power button and restart your iPhone
5. In Ubuntu, right click bluetooth-manager and go to Preferences
6. Set your friendly name and then click Set up new Device…
7. On your iPhone enter the passcode on your laptop
8. Success on pairing!
9. On the computer make sure to check the option to use this as a network connection.
10. Test: Turn off your Wifi on the computer, and click the Network Manager icon, you should see 23:AF:45:BE:12:FA PANU or something similar. Click to connect.

Important notes:

Wifi Issues

Bluetooth does not seem to work well with Wii connections that are active. I tend to get my bluetooth connections dropping out or just plain will not connect. So make sure if you are having problems at all, turn Wifi to remove one more variable from problem.

Cellular Provider

I am with Telus Mobility and they offer the ability to tether on all their smartphone/data plans.

Setup

1. Change the user and password to a user that has ability to access all databases for dump
2. Download and set executable permissions chmod +x backup_databases.sh
3. edit cron to execute every night: crontab -e
4. add: 0 0 * * * /home/james/Dropbox/Home/mobilewolf/scripts/backup_databases.sh &> /dev/null

Ideas for your setup

• The line following “Send databases” replace cp, with scp to send the databases to remote server. You will need to have passwordless ssh connections setup.
• Have the log file emailed to you once completed

My Future Improvements

• Enable backup archiving for the past week rotated daily so I can go back to a database from 2 or 3 days or even a week ago

I have a folder in my Dropbox called Home. Here I have sub folders for each machine that I have. My two laptops, a desktop which hold computer specific files that are different for each computer I have.

Files such as:

• /etc/hosts
• /etc/fstab
• /databases/

Rather than copying these manually, I have simply moved the files to the dropbox and then symbolically linked them. That way when the system updates these files, Dropbox does it’s sync.

The databases folder is a folder which contains database dumps. My crontab is setup to nightly dump databases in tar form and place them here, for Dropbox to store.

I also have a folder called Resources. This contains files that are shared between computers. I have symbolically linked my .fonts folder here. Now whenever I install a new font for a design project, all my other computers are updated too.

For chat software like Pidgin and XChat, I have symbolically linked their folders .purple and xchat2 respectively, to my Dropbox home folder. Because these will be shared between computers I don’t have them in their respect computer sub folder. Now no matter what computer I chat on, my chat logs and software settings are up to date.

Projects that I work on are placed in my Dropbox under a folder called Projects, with each project as its own sub folder.

During my work, or daily routine I tend to shuffle, download, delete, and create new files. While I don’t always place these files to my Dropbox, I am very careful to not hold them on my laptops for long periods of time.

For files that I want to hold, I either move them to my Dropbox or to my NAS server depending solely on their importance and need of accessibility.

The results

I can now format my hard drive at any time, provided that Dropbox has had time to sync any changes. I also have the feeling of security knowing that my hard drive crashes will not take me out of commission.

Alternative method (via the terminal)

If you are just plain lazy, here’s a much easier step.

In your terminal, type the following command:

gconftool -s --type bool /apps/update-notifier/auto_launch false

To recover:

gconftool -s --type bool /apps/update-notifier/auto_launch true

HTC Titan

It has been a long time since I flashed my phone, so I figured I should archive the files I used and the process I took in case I need to do it again sometime in the future. Maybe this will help someone else with the same phone as well.

There are a couple important things before you flash your phone, they seem obvious but….

1. Your first time flashing will be a bitch, if it is your only phone and think you will need 9-1-1 between now and mid tomorrow, do not do it! Remember? Your life depends on it.
2. Backup your data. Use ActiveSync, or whatever software you like, and get your contacts, notes, emails, text messages, docs, etc off the phone. I would suggest getting an SD card 2 GB or better as the space on the phone is a bit limited. It is important to note that simply having an SD card does not mean you don’t have to back up!
3. Flashing will remove the devices usage stats such as lifetime use etc.
4. Flashing will void your warranty.
5. There is a remote possibility if you are not careful, that you could brink your phone, turning it into an expensive albeit flashy paper weight.
6. This is only for the HTC Titan model phone, in Canada it is called HTC P4000
7. Obviously this is for my own personal record and works for me, however, as always make sure you understand the process first so you don’t shoot yourself in the foot.

Benefits to Flashing

1. GPS module is activated (device ships with GPS module crippled)
2. Get the latest OS version and be able to cook your own version
3. Can be more stable and less RAM than previous, or, could lock up all the time and run out of RAM. This benefit is chosen by you.

The Method

I may have deviated slightly from the “standard” way of doing it. Although these instructions are almost identical to other places on the nets, this will work for HTC Titan owners in Canada, if you live in the States, it may differ slightly. Thanks goes to all those crackers out there who risked their phones so we can enjoy our GPS!

There are 5 stages to getting your phone flashed. Follow them very carefully, and read through the instructions a couple times before hand.

At the bottom of the page you can download all the files that I used.

You will need a Windows computer, (preferably Windows XP) with latest version of ActiveSync, and probably Outlook, atleast 250 MBs of free hard drive space, a USB cable for phone to computer, and plenty of paitence.

Stage 1: Retrieving Provisioning Data

Now that all your data is backed up….

1. Get your ESN, MSID and A-Key info by dialing ##778#, that will launch the EPST configuration menu Note: Some carriers (Canadians) do not need the last #, so just ##778
   1. Select view
   2. make note of your ESN (Hex) value
   3. make note of your ESN (Dec) value
   4. make note of your MSID value (looks like a 10 digit tel number)
   5. make note of the rest of the info on a different sheet of paper. And I mean all of it no matter how mundane. This is for backup purposes in case something does not work correctly later. I skipped this, and it took me a month to fix my data connection!
   6. select <view info> and select A-Key. Some carriers leave this blank, some need this info. If there is info here, make note of it now.
   7. click <cancel> to exit the configuration menu
2. Get your EPST
   1. download this file here .. this is the getspl file (in zip form)
   2. run the GetSPC.exe on your phone and in the Input field, type in your ESN(Hex) in the input field (you wrote this down earlier)
   3. press <go>
   4. the number produced in the output field is your MSLNumber (EPST unlock code)
   5. exit the application

You should now have noted these 4 items:

1. MDN: your 10 digit tel number
2. MSID: another 10 digit tel number (for some carriers it’s the same as your MDN)
3. A-Key: only required by certain carriers
4. MSL: a 6 digit number that you got when you ran the GetSPC.exe

Special Note: The great thing about using the following procedure is that typically you won’t even have to use the information you just obtained. But better safe than sorry.

Stage 2: Upgrading the Boot Loader & Radio

1. If you have flash this phone before, you will need to “relock” the phone so it can be flashed. If you have not flashed your phone or do not know what this is, skip and continue as you most likely have a virgin phone.
   You can get the relocker here: XXXXXXXXXXXXXXXXXXXXXXXXXx
2. Run the Unofficial carrier released rom 3.16 which contains the boot loader and radio. This is a Sprint ROM, don’t worry about it, you’ll still be able to use your provider, in my case, Telus.
   You can get the ROM here: XXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Stage 3: Install a Custom ROM

I am running No2Chems ROMs which I find are very good and still feels like the stock ROM (how my phone was meant to be) but with some added features.

1. run the unLocker for 3.16 and above, don’t worry about getting out of the boot loader – tri-color screen
2. Download: No2Chems ROM version 5050 (old version as of writing but I still use it) XXXXXXXXXXXXXXX (warning 50mb download)
3. Download the RUU, the software used to flash the phone. XXXXXXXXXXXXXXXX
4. Copy the .nbh file into the RUU folder
5. Make sure there is only one .nbh file in the folder
6. Double click RomUpdateUtility.exe to begin the update

Stage 4: Verify Provisioning Data

1. Dial ##MSL# – this is the 6 digit code you retrieved in step 2 above
   1. first select view (because if your info is correct, we don’t want to accidentally mess it up
   2. verify that the MDN and MSID fields match your info from above
   3. if the info matches, select cancel and skip following step.
   4. if the info does not match, then cancel and re dial ##MSL#, but select edit.
   5. input the correct MDN and MSID and then select <menu> and <ok> and your phone will now reboot. Check again to verify its correctness when the phone boots up.
2. If your phone had an A-Key then do this step, otherwise proceed to step 3
   1. dial ##778#
   2. select <edit>
   3. input your MSL (6 digit code retrieved in step 2 above) **Please note, you can mess up your phone if you change the wrong fields – use with caution**
   4. select <view info> and select A-Key
   5. input the A-Key from info above (if required)
   6. select menu and select <OK>, your phone will reboot

Verify your services

1. make an outbound call
2. receive a call
3. connect to the Internet

Congratulations, you have successfully updated your phone – Have fun!

Stage 5: Trouble Shooting

More to come here, just want to push this article out.

However, Gnome likes to place all these “handy” icons on the desktop that invade my cleanliness. And depending on what hard drives I have plugged in, SD cards, and mounted NFS drives, it easily becomes a Where’s Waldo issue!

Here is a tip to take your desktop from this:

to this:

In a terminal, enter:

gconf-editor

Similar to Windows Registry Editor, navigate to get to /apps/nautilus/desktop

Check or uncheck the items you do or don’t want to see on the desktop. Feel free to Bookmark the location for faster access so you can unhide those pesky devils when you need them the most.

Close the program and voila!
