Sex and the City has been recently in the news for the world premier in London of the cinematic follow-up to the successful TV series. According to the film’s marketing team, they are creating smallish premieres in Europe, the next one will be in Berlin, in order to create enough suspense for the New York premier which will be ‘enormous’ and will happen just before the film opens worldwide, which is set for May the 30th.

For all the millions of fans of this fantastic series, I’ve found a great screen saver which will bring to your desktop all the allure of the four stylish women and that feeling of friendship, love and disillusion-illusion, that so appealed to so many of us.

Although the screensaver should allow you also to save the images as wallpaper, this function didn’t work when I tried it, so I though of making your life simpler by taking screenshot and zip them in this Sex and the City wallpaper collection, which I’m sure you’ll love.

If you really are a fan of the series, try this Trivia Game at HBO to find out where you rank on the Sex and the City scale. It will be also funny to test yourself to see with which character you have most affinity with: whether you are more like the high maintenance Charlotte, the pragmatic Miranda, the sexy Samantha, the all-in-one Carrie or a mix of them.

If you are a man, it’s still interesting to know which kind of woman you would be if you were one. I’m something in between Carrie and Charlotte. I just don’t live in Manhattan and would have some problems in buying a pair of Manolo Blahnik a week; but that’s just a matter of perspective, isn’t it?

If you’re a Twitter fan then you’ll know that it’s not particularly well integrated with your desktop. However, there are two very simple solutions which can transform the way you use twitter - Twhirl and TwitterFox. Thanks to Adobe Air, you can now integrate twitter with your desktop much more easily courtesy of twhirl? By doing so, you can keep your status constantly updated quicker, improve your communication options and even change the look of twitter. In particular, it makes adding new friends much quicker and easier than in Twitter’s standalone version. In addition, this is a cross platform Twitter extension that works on both Windows and Mac and connects to multiple twitter and Friendfeed accounts. It provides instant desktop notification of new tweets and even allows you to post images to TwitPic. Also useful is the fact that if you’ve been pestered or bothered by either spam twitters or just someone really annoying, the most recent version also allows you to block other users. The tricky part is configuring it though - if it’s not done correctly, you run the risk of being stuck with old tweets every time you log in and being frozen out of twhirl occasionally although there is a very good user forum to seek help in. Keep track of the latest releases and developments on the twhirl blog.

However, the big downside of twhirl is that it requires installation of Adobe Air. In my opinion, it’s worth doing this although if you’re working a low spec machine, then it may be wise to avoid it. If this is your case, then you’d be much better seeking a lightweight solution in the form of TwitterFox. TwitterFox allows you to enjoy similar advantages to twhirl but the difference is that it simply plugs into Firefox. TwitterFox sits on your Firefox status bar for instant access to your friends and status changes. However, you can’t block contacts or post images like you can with twhirl although on the upside, it requires virtually no configuration whatsoever. One other minor criticism is that as you type, TwitterFox counts up to 140 characters rather than counting down which would be much more helpful because you always have to remember not to go over the 140 twitter character limit.

In summary, there’s probably little doubt that twhirl offers you more functionality than TwitterFox. However, it also requires more configuration and you’ll probably experience quite a few teething problems setting it up. If you’re just looking for a little better integration with your desktop and are working on a slow machine, go for TwitterFox. If you’re a serious twitter user, then you should definitely give twhirl a whirl.

If you only use your iPod to listen to music, you’re missing out on loads of extra things you can do with it. There are many utilities out there to help you convert and transform your iPod into an array of tools such as a video player, storage device, news reader and note taker. Of course, if you’re going to fill it with movies then you’ll need to delete all those albums that are hogging space on your iPod’s hard drive but it’s worth doing, considering you can get all of this out of it:

iPod Video Converter For Free - No ads or fees - just convert films to watch on your iPod

PodPlus - Allows you to transfer everything from e-mails to RSS feeds to your iPod

MojoPac - Transform your iPod into a secure USB storage device

todoPod - Use your iPod to compile lists and store your thoughts on the move

iPodifier - Grab TV streams on your PC and watch them later on your iPod

Windows: Security is probably one of our main concerns as computer users. This is why we all should take it seriously and use the necessary security apps to protect our system and personal data. AVG 8 is an excellent choice to avoid virus infections and stay safe while browsing the web. This last version features a totally revamped interface and a new anti-spyware tool.

Mac: Do you find you’re having a hard time remembering login info for all your domains? DomainBrain is a smart little app that lets you store all your precious information and easily protect it with a password. You can organize entries in nested folders and view all your information in one go. DomainBrain should ensure you never forget login info again.

Pocket PC: If you can’t afford to hire a personal assistant to take care of your daily schedule then simply install Pocket Informant on your PPC to do the job for you. The application offers a more powerful alternative to the built-in Calendar/Contacts/Tasks applications, to help you better organize your time. What’s more, the program syncs with Outlook, ActiveSync and other sync solutions.

If you haven’t upgraded to Office 2008 yet, then you’ll still be stuck with the templates offered by Office 2007 for your letterheads, envelopes and business cards. However, Microsoft have just released 6 free new professional looking templates for Office 2007 that can spruce up your presentations and business materials. If you haven’t even got Office 2007 yet, the template download page offers a free sample.

Once you’ve downloaded the templates there’s a slightly different installtion procedure depending on which Office application you want to use them in. In Powerpoint, simply click on the “Design” menu and in the Themes group, click the “More” button. From there, you’ve got an option to add custom templates. In Word or Excel you’ll need to use the Page Layout tab and in the Themes group, click Themes and browse to the themes you’ve just downloaded. Note that you may receive the error message “The template cannot correctly be downloaded” when you try to install the templates. This is actually a bug and you’ll find that the templates have installed and are ready for use but Microsoft claim this is a download error that they’re currently working on to resolve.

Widgets are all the rage now enabling users to drag and drop their favourite applications and functions onto their desktop for easy access. However, until now, the widget phenomenon hadn’t caught up with video players (except arguably Joost) but new open source player Chameleo enables users to watch and create visually-rich video applications with interactive widgets.

Chameleo is based on GStreamer and supports just about every codec out there so there are virtually no playback problems. What makes it interesting however is that it offers a variety of widgets which enable you to perform a variety of tasks from taking instant screenshots to blogging about what you are watching. Even more exciting, you can create your own widgets because it takes it’s plug-in architecture from Eclipse to make it easy to extend with a minimum of programming experience. One warming however - it is extremely resource hogging so make sure you’ve got plenty of RAM! You can see Chameleon in action below and follow the latest developments here.

A few weeks ago I showed you how to create your own customized ringtones for the iPhone using a handy software tool called ToneShop. But I recently discovered a very simple trick that enables you to convert your favorite MP3 into an iPhone ringtone right from the iTunes interface, without any third-party apps.

Launch iTunes and choose any MP3 you like. As the maximum ringtone length supported by the iPhone is 30 seconds, you’ll have to trim it a bit (don’t worry, this trimming doesn’t change your original song and can be reverted at any time). Right click on the file, select Get info and click on the Options tab. Insert the file’s start and stop time and click on OK.

Now go back to your Library, right click on your chosen MP3 and select Convert selection to AAC. You’ll get an AAC file with exactly the same name under the highlighted file. Open a File Explorer window and browse to your iTunes music folder (usually C:\Documents and Settings\username\My documents\My music\iTunes\iTunes Music). Locate the song you just converted, which will appear now as an M4A file, and change the extension to M4R. Read the rest of this entry »

Adobe AIR (which used to be know as Apollo, remember?) is slowly becoming a solid software platform for developers, especially those who work on their own and don’t belong to any big company. But what is this AIR thing about? AIR is a runtime coding environment that enables developers to create web software tools, working in between a web-based app and a native desktop utility. AIR apps typically include Internet elements such as HTML, Flash or Ajax, but are launched from your computer as you would normally launch any other program.

How do you install AIR apps? First of all, you need the basic component, Adobe AIR. Then, simply download the AIR tool you’re interested in (usually a file with the .air extension) and double click on it. You’ll start up an installation process similar to this one:

Click on “Install”, select the program’s location on your hard drive and you’re ready to go. When the installation is finished, run your newly AIR app as you would run any program.

There is already a wide range of AIR tools available to download, covering all sorts of areas: from Twitter clients to microblogging tools, including web stats analyzers or even RSS feed readers. But if you want more, take a look at Freshairapps: they have an extensive catalog with all the latest AIR apps out there, together with top rankings, news, tutorials and other AIR resources.

If you’re anything like me, you’ll find iTunes to be an essential part of your working day. Whether I’m listening to my favourite podcasts or concentrating with the help of some soothing music, iTunes stays running all through the day. Which is why I started to become pretty worried when a recurring error started to appear recently. Each time I start iTunes, I receive an error warning stating that “The iTunes Library file cannot be saved. An unknown error occurred (-48)“.

It took me a bit of time to work out how to fix this problem, so I thought I’d pass on what I found. This error basically stems from iTunes not being able to write its Library file to your iTunes folder. To fix it, simply find your iTunes folder (located in My Documents > My Music, in my case), right click the folder’s icon and choose ‘Properties‘. From here, click ‘Advanced‘ and make sure that Fast indexing is switched off for the folder. Also, make sure that in the main properties dialog box, ‘Read only‘ is completely unchecked.

This worked for me, but let me know if you’re having further problems with error (-48).

It can be very annoying when you install extensions in Firefox, change themes or alter a configuration file and are then informed that you must restart it for the extension to take effect but are offered no option for doing so. The answer to this problem is - yes that’s right - another extension called QuickRestart.

QuickRestart allows you to instantly restart Firefox via keyboard shortcut “Ctrl+Alt+R” or an option in the file menu “Restart Firefox”. It’s a very useful little extension if you’re an add-on freak like me, although it would have been nice if they’d added a restart button to the extensions dialogue window because after all, that’s where you’ll need it most. Because of this, in the end it’s almost as quick just to close the browser and restart it again although the desktop shortcut speeds things up a little. This extension also has the advantage that there’s no annoying “Are You Sure?” prompt when you restart Firefox although the disadvantage of course is, if you press the desktop shortcut accidentally, you lose all your information.

Note that if you’d rather have a restart button on your Firefox toolbar, then you can use the Toolbar Buttons extension which includes a range of buttons including one to restart the browser.

It was only a matter of time before Google announced the launch their own security product and Google Web Security for Enterprise is their rather long winded but comprehensive security solution aimed at large networks and businesses. The suite, which scans in real-time, stops web-borne spyware and viruses before they infiltrate networks and compromise or disable computers.

However it also enables network administrators to control how employees use the Internet so they can create, enforce, and monitor a web policy to “protect you from the legal liabilities of inappropriate content, reduce bandwidth congestion, and improve employee productivity”. You’ll also notice that this is one Google product that isn’t plastered with Google branding however as the software giant has chosen to brand it under the name of developers Postini who have provided much of the infrastructure.

It even protects employees on the move whether they are working at home, in a hotel room or Wi-Fi spot. It enhances the privacy of such employees by automatically encrypting all web traffic when the user connects to a public network and eliminates the need to backhaul traffic over corporate VPN’s. Of course, as you would expect from a Google product too, it’s very easy to use even for novice network administrators.

Looks like bad news for employees surfing those prohibited sites at work then although Google’s classification system for what it considers gambling, dating and news related sites etc may allow for a few exceptions to squeeze through. And this will surely become one of the major targets for hackers and trojans if it becomes widely implemented although probably, no serious enterprise would rely on a Google product to protect their network.

Pocket PC: We all know how good Google Maps is for finding your way from A to B, but did you know you can also hook up the powerful mapping service with your GPS receiver? Google Navigator provides a quick and easy way of obtaining map and location information using your GPS-enabled Pocket PC.

I’m a big fan of Google products in general. I use Gmail and Google Reader on a daily basis, not to mention my constant queries to the search engine. But due to a natural tendency to lose my bearings anywhere, I have a special predilection for Google Maps.

This awesome world atlas can show you images of just about any location on Earth, sometimes with such a high level of detail that you can perfectly distinguish cars and people walking around. But there are many other ways to use Google Maps than just watching life as it goes on in the antipodes. Thanks to customized maps created by certain companies or by other Google Maps users, you can add new content and tools to your maps and make them even more useful.

Simply load Google Maps on your browser and click on the “My Maps” tab. You’ll be presented with a selection of several map overlays, all ready to use at a single click. If you click on the “Browse the directory” button, you’ll access a larger list featuring all sorts of Google Maps add-ons: tools to calculate distance between two points, check traffic conditions in your city or search for hotels, maps for transportation networks around the world, lists of popular monuments and landmarks all over the world… even a real-time earthquake tracking tool!

Installing these extra features is a piece of cake: browse the collection until you find one that suits your needs and click on the “Add it to Maps” button. Now go back to Google Maps via the top left link and the new information will be displayed right on your map.

Upgrading your RAM is one of the best ways to speed up an old laptop. As applications get bigger and the number of programs you install increase, the demands on your RAM also increase. Add to that graphics-heavy online applications such as Google Earth and those exciting Web 2.0 apps and you can see why having enough RAM is essential for smooth functioning of your PC.

Nowadays, if you’re running on anything less than 512MB RAM then God help you - you must be suffering some awfully slow PC usage. However, even 512MB is not really enough nowadays - you’ll need to double it to get the most out of your PC but before you do anything, you’ll need to know exactly what type of RAM your laptop or PC uses. Here is a 5 point plan for upgrading your RAM:

1. Check whether you have any RAM slots free - You should check your manual to find where your expansion slots are - in the case of laptops, they are usually on the bottom of the machine. You should find between two and eight same-sized parallel sockets on the main circuit board.

2. Check whether your RAM is parity or non-parity - Determines whether a random access memory unit stores a parity bit for error detection purposes.

3. Find out the speed of the RAM you currently have (in nanoseconds) - Buying RAM of the wrong speed will conflict with your current RAM and not work.

4. Check what type of modules your PC uses These will be either Single In-Line Memory Modules (SIMM’s) or Dual In-Line Memory Modules (DIMM’s) - There’s only a subtle variation in how they look but buying the wrong one means it simply won’t fit in the slot!

5. Check the number of pins on your motherboard - This should be 30, 72 or 168. Use this motherboard-RAM guide to see which RAM is compatible with your motherboard.

Once you’ve established all this information, it’s time to head to your local PC dealer or buy the RAM chips online. Remember that once opened, it’s very hard to return components such as RAM. If you’re unable to ascertain any of the above data, then it’s better for you to take you laptop to your dealer. However, if you purchase online, usually they will specify the exact RAM you need based on your laptop or PC model so you should have no problems.

Upgrading RAM is one of the most effective and easy ways to speed up your PC and even better, it’s not very expensive. I just checked-out an additional 512MB RAM for my Acer Aspire and it costs less than $30. So what are you waiting for - pump-up your RAM today!

Windows: If the standard Windows Explorer is too limited for you, you need an advanced file manager like Q-Dir. Thanks to its multi-pane interface with customizable layouts and file color codes, you can move and copy files or folders in a much easier and faster way. Plus, it doesn’t require installation and can be conveniently run from a USB key.

Mac: The following program is also related to USB keys. Curb lets you clean the trash from your removable media. Drag and drop your key icon onto its interface and it takes care of trashing files for you. You have four different options for secure removal (including 35 pass!) of the files, making this a simple yet secure solution to trash files from USB keys.

Don’t get me wrong, I think the Pocket PC platform is awesome but, like many people, I find it a little cumbersome sometimes and the fact that I have to tap tiny icons. Pointui Home changes all that, skinning the Windows Mobile interface and allowing you to control your device’s basic features using your fingers.
