Well it might, but there is a chance you might be able to undelete the message – and quite easily if you’re on a Mac or a Linux machine. Here are the few steps, which has helped recover a lost mail or two… First close Thunderbird. Then located the mail directory (on Linux it’s located in the subdirectory .mozilla-thunderbird in you home directory – on windows most likely somewhere in C:\Documents and Settings\*\Application Data\Thunderbird – In there you’re looking for the “Local Folders” directory.

If you’re on a Mac or Linux type the following:

cat Trash | grep -v X-Mozilla- > Restored

The cat command prints all the line in the file Trash – not to the screen, but as input to grep. Grep is used to find all lines not begining with “X-Mozilla-” and prints these – and the greater than makes the print go to a new file called Restored.

Once this is done exit the directory and restart Thunderbird. You should now be able to find a new folder called “Restored” and a lot of old mail. Find the message you need to restore, and drag it into the inbox or wherever you need it – then delete the “Restored” folder.

If you’re on windows you need to do a little more work. The trick happening with the command line above, is that all lines beginning with “X-Mozilla-” is deleted and thus restored from their deleted state. A suitable editor might do the trick.

Do notice, that the Trash folder may be quite large, if you haven’t run the “Compact Folders” in quite a while – and if you did do that after deleting the message you’re trying to restore, then it’s probably gone for good.

The first shot at changing the ip number, was going to the “System” menu, choosing Administration and Network Tools. It sounded just about right – but it’s wrong. Sure you view settings and some statistics, but it’s all read only.

So, if you want to change the IP number, go to your top panel (in the right side, you’ll find you network icon. Right click on the icon and choose “Edit Connections”. In the window opening, you’ll have access to changing the ip number – to manual configuration, DHCP with ip number only or (as is default) full DHCP configuration.

Choosing “Automatic (DHCP) addresses only” allows you to get an automatic IP, but use openDNS’ DNS-servers – should you prefer them over the DNS servers provided by your ISP.

It’s a fairly simple game. You’re in control of an Airport and all you have to do is make sure the planes land at the runways. To do this you simply draw their designated paths on the screen. There are 4 different aircrafts – helicopters, propeller planes, small jets and large jets. As you play more planes concurrently enters the airspace – and eventually it gets quite busy and avoiding mid-air collisions a challenge.

In the recent update of the game two new airfields was added to the original, and with the different layouts, new strategies for keeping the planes from hitting each other must be developed.

The sound in the game is nothing special, but that really doesn’t matter – once the airspace gets busy you really don’t have time to listen – and if you like you can disable sounds when the game launches and keep listening to podcasts or music.

The game is currently (at the time of writing) on sale for 99 cents – buy it now (AppStore link) and you’ll have hours of entertainment.

Installing the firewall

The firewall should be available by default, but there isn’t a GUI application installed for the firewall. Open your favorite package manager and install the “gufw” package.

sudo apt-get install gufw

Once installed the firewall can easily be turned on and of – and controlled from the System -> Administration -> Firewall configuration menu item.
I set the current configuration to “Deny incoming traffic” and enabled the firewall (beneat the shield). This is probably all most desktop users needs to do.
On my laptop, I am running a SSH server. I do this as a way to fetch files I may have forgotten on the machine when leaving the laptop at the office – or use it as a jumpstation to other machines.
Adding a rule in the firewall, which allows incoming SSH traffic was a simple matter of choosing the “preconfigured” tab, and there adding a rule allowing SSH traffic.

The firewall can be configured with much more advanced options, but if you really need that, you probably (or hopefully) know what to do, but for regular users having an easy to use firewall and an uncomplicated interface to manage it, is just great and one of the cool new features of Ubuntu 9.04.

sudo apt-get install libmotif3
sudo ln -s /usr/lib/libXm.so.3.0.2 /usr/lib/libXm.so.4

download the most recent client from Citrix.

mv linuxx86-11.0.140395.tar.gz  install_tmp
cd install_tmp
tar zxvf linuxx86-11.0.140395.tar.gz
sudo ./setupwfc

After finishing the install remove the “install_tmp” directory.

From here on it’s a matter of configuring the Citrix Receiver to your specific environment.
In my case, I gad a backup of the old Ubuntu installation, and I fetched the “.ICAClient” directory from my home-folder and putting in the same place on the new installation and no configuration was even needed.

It’s a small device, which plugs into a USB port, and to the computer acts as a keyboard. It has some advanced security build-in with the ability to generate one-time verifiable passwords, but is incredible easy to use – plug it into the USB port and press the single button when you need to sign in to services supporting the Yubikey.

I’ve been useing it with OpenID sign-ins and WordPress logins, and it’s worked flawless everytime. The only important thing is to remember the Yubikey – without the little hardware token, you’re lost. If you need a secure sign-in solution, listen to security now to get the technology explained and contact Yubico, it’s seems to be as affordable as it is easy to use (and no, the post isn’t paid or sponsored, nor do I know anyone at Yubico).

I’d like to suggest a 6 month feature freeze to all smartphone developers, and suggest they stop inventing new features, and poor resources into fixing existing features already available in the existing phones – and the first three issues they so focus on are:

1. Battery lifetime.
Any phone should last at least 72 hours with “reasonable use”. Sure reasonable use may be a though term to define, but the iPhone reviews seem to suggest an expected battery lifetime well below 24 hours. My current SonyEricsson P1i can usually last about 48 hours (if I don’t use the Wifi at all).

Most specifications define an expected stand-by time and an expected talk time. I’d like to suggest the stand-by time is with all features enabled but no active – GPS, Wifi, bluetooth and 3G. I’m not sure how to replace the expected talk time with a better figure, but the standby time is certainly not 440 hours with wifi and bluetooth enabled (but unused) – it’s more likely 20 hours.

2. Faster.
Every time I’ve gotten a new phone (the P800, the P900 and now P1i), it’s become slower for every “upgrade”. It’s not just an SonyEricsson issue – the Nokias, HTCs and other brands I’ve tried seem to suffer from the same problem.

I’d like the software optimized or a more powerful CPU in the phone thank you.

3. Improvement on existing features

Most phone has a legacy, but sometimes you need a clean slate and a fresh start – and on most of the current smartphones it’s long over due. New features are cool, but it’s been happening way to fast, so the features (how they work) has far to often become a mess.

.. and to make matters even worse – with the explosion of new features and available applications on mobile phones, the user interface (where the features are located and how they look) has also be come a mess, and often it seems large parts of the software was slapped together in the last minute.

Please so making new features. Work with what you’ve got.

It’s a pretty bad situation in terms of security and software maintenance/updating.

WindowsUpdate has come part of the way. It’s easy and simple for even common users to use and stay fairly current with the core windows system, but it only covers a small piece of the puzzle. While most windows machines I’ve encountered seem to have Office installed, WindowsUpdate doesn’t cover it – OfficeUpdate does, but how many people know of that? – and run it on a regular basis?

Some software (a lot it seems) have build-in phone-home functions, which allow them to check for updates on a regular basis – if it’s available and you have enabled the checks, another piece is solved.

Wouldn’t a one-stop solution seem much nicer?

Well it seems Secunia has come very close to providing just that with the Secuina PSI.
The PSI – Personal Software Inspector – is a little scanner, which scans your hard drive for installed software (windows, office, drivers, applications, utilities) and checks it against a database with software versions and security issues in the various versions. If it finds issues, it describes the issue and provide links to where updates for the software can be found.

I’ve played a with it while migrating one of the Windows Machines at home to new hardware, and so far it’s been quite impressive. Give it a try – it’s available for personal use  from Secunias website.

One of the first things I discovered is that things are more “binary” in the Mac world. If you have an external device it either works with the Mac or it doesn’t. There isn’t that middle ground from the windows world where it almost works, but not quite – or worse it works in even week numbers but not when the sun shine.

Another thing I fear I’ll discover after the next Apple World Wide Developer Conference is their will to leave things behind. Microsoft has an impressive – maybe even amazing – record of backwards compatibility. Almost no matter how they move forward, they never really break anything backwards. Apple on the other hand is pretty hard on legacy – if you can’t keep up, you’re left behind. They were among the first to drop the disk drive, and they been much more efficient in moving their user base to the current version of their OSX (not quite like Microsoft, which seem to have a hard time getting their users on to Vista).

I’m afraid they’ll announce that the next version of OS X – the 10.6 – is Intel-only – leaving my PowerG5 behind. It doesn’t feel like an old nor slow machine, but once Apple decided it’s too old – it really doesn’t matter – and I better start saving some cash for a new Mac.
