Help Desk - 21st April 2006

This week a very naughty reader tries to connect to a WiFi network and another asks about the very important issue of backing up your data.

Q) I have a WiFi enabled laptop and have noticed that there is a connection available near my house. However, it shows up as “security enabled” and I cannot connect to it. Can you tell why ?

From Terry N - Torrevieja

A) l Terry, the first thing I have to tell you is that you really shouldn’t be trying to connect to any WiFi network without the owners express permission.

One of the biggest problems in the WiFi Internet world is what we call “Freeloaders” or “War Drivers” who connect to unprotected wireless networks and use the bandwidth that others are paying for !! Not the nicest or most honest thing to do !!

If you need to connect to the internet then I suggest you either visit an internet café or get a connection in your own property via Telefonica (chance would be a fine thing for most !!) or through a provider like Wi-Surf. From the location you gave, I believe we can provide you with a high spedd broadband internet connection and phone all of your own !! Just visit our website at www.wi-surf.com for more information.

As to the “Security Enabled” issue, this means that the WiFi network you are trying to connect to is using either WEP (Wired Equivalency Privacy) or WPA (WiFi Protected Access) to restrict access to their network to users who have the appropriate “key” or Code”. Without this code you simply will not be able to connect.


Q) I know backing up my files is important but I'm not sure how important it really is ?

From Nigel M - Benidorm

A) A back-up is intended to prevent you from losing your business critical data. Sooner or later, you will loose the data on your computer. The computer's hard disk will crash, an accident will happen, or something such as a severe virus will come along. To assess how important your data is, make a list of all the information you use on your computer. Examples include: customer data, financial information, contact information, letters, company collateral or even recordings. When the list is complete use it to answer the following questions:

Ø Would your business be able to run without the data?
Ø Would your family be able to run without the data !!??
Ø Is the data replaceable and what effort would it take to replace it?
Ø Is it used for strategic planning?
Ø Are you under any customer obligation to retain information?
Ø Are you under any legal requirements to retain the information?

Backing up your data is the only way to protect yourself from all the possible ways you can loose your business data.

The easiest way to do it is to simply use Windows Explorer to select and copy the files you want to protect to a floppy disc, USB Memory stick, tape or CD/DVD.

If you want to get a little more organised (especially important in a business environment) you can use Window’s own integral backup application to schedule and create backups automatically or, alternatively, there are many packages on the market that do a great job. Depending on the importance of your data, you should be backing up either daily or weekly or whenever you change an important file.

Surefer's Corner - 21st April 2006 (Digital Photography)

Below is a range of sites that will give you an excellent starting off point for your venture into the world of digital Photography.

Luminous Landscape (www.luminous-landscape.com)

Michael Reichmann's masterful site bills itself as "the web's most comprehensive site devoted to the art of landscape and nature photography using digital imaging techniques." I couldn't agree more. Scanned film images are the usual raw materials here, but from there on, it's pure Digital Photography gold - especially the PhotoShop tutorials, which I would think can usually be applied to any competent photo editing software. Michael's Instant PhotoShop tutorial is an invaluable leg-up for anyone contemplating digital photo editing, but be sure to continue on to Miles Hecker's tone curves tutorial. Since November, 2000, Michael's been teaming up his enviable collection of high-end EOS lenses with the widely acclaimed Canon EOS D-series digital bodies.

Digital Photography Review (
www.dpreview.com)

Phil Askey's comprehensive, easily-navigated one-stop sponsored Digital Photography site has also been around since day one. The side-by-side camera comparison pages are a godsend for serious camera shoppers. The how-to articles and user forums are well worth bookmarking. Oly users will find a wealth of practical information on the Digital Photography Review Oly Talk Forum.
Steve's Digicams (www.steves-digicams.com)

Steve Sanders' superb DP site has been a pioneering resource in the DP arena. Reading the thoughtful and candid full-length camera reviews here will get you up to speed on your camera faster than reading the manual! Steve also reviews and illustrates many valuable accessories.

Dave Etchells' excellent site offers DP news, reviews and tests, but it's particularly notable for its many superb how-to articles.

A list of photography related sites without Kodak is pretty unthinkable. Click on the “Consumer Photography” link on the menu and you will find a range of useful resources including a range of hints and tips when you click on “Taking Great Photos”

Snopes.com (www.snopes.com)

An excellent repository of some of the more famous photographic “cons” along with many other weird and wonderful pics that are actually real !!

TechnoBabble - 21st April 2006 (Digital Photography)

With the advent of Digital Photography (DP) along with what is now cheap and easy access to Digital Cameras and Photo editing software, there aren’t many of us who haven’t taken digital photos and played around with them on the PC. Let’s face it, almost every mobile phone you can buy now has a pretty reasonable digital camera built into it !!

Whether it’s a serious hobby, creating a family album, making great Aunt Mabel’s nose look bigger or putting Bob’s head on Jenny’s body, the opportunities for fun and games are endless.

Not only can you take photograph after photograph without ever having to visit the chemists or “Supasnaps” to get them developed, you can download them from your camera or phone to your PC and utilise a whole range of easy to use software to enhance and manipulate them.

My daughter Chloe has created a website for her and her friends where they all upload photos taken on their mobile phones, creating a fun and interesting record of their teenage adventures !!

I also have a friend who, after spending most of his life as an accountant, got into DP when he was made redundant. To see what he has done in terms of both the taking of the photos and the subsequent “manipulation” of them on his PC is amazing. It really is an art form and I am trying hard to persuade him to publish on-line.

Remember that old saying “The camera never lies” ? Well, it no longer holds true !!

Whilst many doctored photos are just funny, like the one of a man hoisting what appears to be a 90-pound cat (huge isn’t it !!). The bottom line is that sometimes faked or altered images are potentially dangerous because they reflect a certain reality, altering people’s opinions and sometimes their beliefs.


Such was the case with a manipulated photo that appeared on the Web in 2002 that showed President Bush holding a book upside down during a visit to a school in Houston. The image was clearly meant to be funny (I think it was !!). However, although it was quickly revealed to be a fake, the photo served to reinforce the often touted viewpoint that President Bush is a tad intellectually challenged !!


So, how do all you budding David Bailey’s out there get in on the act ?!?

Whilst it is possible to spend thousands on either a digital camera or Photo Editing software, it is also possible to get started very cheaply and easily.

When looking at Cameras, the choice is enormous, ranging from the cheapest basic cameras costing as little as €30.00, to the very latest professional quality Digital SLR’s costing thousands. Whatever you need, there is a camera out there for you. I suggest to kick off you look at our Gadget of the Week and also a number of the sites given in Surfers Corner that give excellent advice on choosing a Digicam and reviews of the best available.

As to Software, the “industry standards” in Photo Editing software such as Adobe Photoshop (www.adobe.com) are very expensive and not accessible to all as a result. There are some excellent budget priced packages out there and even some free ones. Of them all, Corel’s “Paint Shop Pro” (c€45.00 – www.corel.com) is very highly regards and easy to use. Of the free packages, Serif’s “PhotoPlus” is in my opinion about the best (www.freeserifsoftware.com).

When it comes to storing your photos, you can keep them on your PC, create CD or DVD “Albums” or even upload them to your own or one of the many “gallery” sites on the Web. In fact, there are a whole range of free software packages available on the web that will help you organise your electronic albums. One of the best, I think, is “Cheez” (www.cheez.gr).

For printing, there are w whole range of very affordable inkjet printers on the market, with Hewlett Packard (www.hp.com) and Epson (www.Epson.com) offering some of the best. When you use a good “photo quality” paper (freely available from good stationary stores, PC Stores etc.), the results are as good as anything you used to get from Boots !!

Happy Snapping !!
