Image File Formats
On the web today, GIF, PNG and JPEG are the most common and widely supported image file formats. Choosing appropriately, cropping and resizing images is important to keep pages lightweight and quick to load. Below is a guide to explain how each of these file formats work, when to use them and why.
JPEG format is intended for photo-style images only: photographs, movie stills, computer game stills, etc.
The GIF and PNG formats are ideal for compressing graphics that contain flat areas of plain color, as well as text.
Use PNG to compress text, line art, comic strip style illustrations, screenshots of applications, etc. As a lossless format it won't distort or alter the original image and allows fine lines and other details to be reproduced accurately. For typical web use, stick to 8 bit (256 color).
Today PNG has largely replaced the GIF format. GIF is traditionally used for line art, text or comic-style illustrations where the 256 color limitation is desired. Many feel that the only real value in the format is for animations.

10 Top Tips for youer computer safety.
10 Top Tips for Business Computer Safety
Author:
Ian Spencer
Well we have put together these helpful tips to help small business owners.
- Firewall, you have probably heard about a firewall, most broadband routers have a small firewall built in. Make sure its enabled. Be sure to block traffic on port 3389. This is a common port used for hackers.
- Windows Firewall, found in control panel on your computer, make sure this is enabled
- Anti Virus, ensure you have a full edition of anti virus on your computers, you will need to pay for protection but its worth it. I would recommend Symantec for a small business
- Anti Spam, ensure you have a good spam filter, you don\'t need to install software, this can be managed before the mail reaches your server or PC
- Sending Email, if sending to more than 3 or 4 people, ensure you use BCC instead of TO, you have a responsibility to keep peoples email addresses secure. If unsure ask someone.
- Passwords, always ensure you have a password on your computers, change this regularly and don\'t tell people what it is, use a mixture of uppercase and lowercase, include numbers and symbols. A good length is 8 characters.
- Acceptable Use Policy, make sure your computer users all sign an acceptable use policy, this offers you added protection by employees agreeing to use equipment appropriately and for work use only.
- Wireless Networking, if you have wireless networking in your office, make sure its secure, avoid WEP, as a minimum ensure you are using WPA-PSK encryption. Also, ensure the security key is kept secret, that way you avoid members of staff adding their mobiles to your network and using your internet connection.
- Remote Access, if you want to access your system remotely ensure you use methods of encryption on the connection, a VPN creates a secure connection between you and your business network, use this method to transfer data when you can. Alternatively use remote desktop to a PC in your business network rather than directly to your business server.
- Management & Support, if your not an IT expert then you should employ the services of someone who is. This can be on a formal Pay As You Go basis, so they have a basic understanding of your setup and needs, and you only pay for help and support when you need. If you have a server then you should certainly have a formal support contract in place. A good IT company will provide monitoring, management and support for a small monthly fee. Price would depend on your individual requirements. Organisations with formal agreements in place are better protected as systems are monitored and patch proactively.

Web Design Tips
Here are a few tips to get you on the right path to making attractive SynthaSite websites. Keep in mind your reasons for creating a website in the first place - the aim of your site should dictate the manner in which you approach its design.
By now you must have some idea of what it is that you wish to achieve by having a website. Whether it's to raise the online profile of your company, promote and sell your services or products on the web, or just jot down your daily ramblings in a blog, the aim of your site should dictate the manner in which you approach the design and building of it.
• Organise your material ahead of time - placing images and documents into folders.
• Keep your navigation simple, precise and well ordered. Leave room for new sections.
• Avoid the use of over-long text - not many folks have the ability to read reams of information on-screen.
• Look & Learn. Look at other websites and learn what works well (and doesn't!). www.designmeltdown.com is a great source of inspiration.
• Choose an appropriate Style for your website. There are 60+ templates available, so you should find something suitable.
• Be consistent in your use of colour, image treatment and tone of voice.
• Ensure that your copy is easy to read. Use the two-column widget to split content into columns. Avoid fancy fonts and excessive use of gaudy colour.
• Avoid large image, video or audio files. Be sure to optimise all files. For images, use 72dpi and jpeg as a guide. Try to keep your page lighter than 300k.
• No-nos: Too many animations, under-construction signs, slow page downloads, grammatical & spelling errors, centred text paragraphs, and empty pages.
Mostly, it's just a case of learning to avoid those features that guarantee to make a site look amateur.

How to unintall applications freely and efficiently
f there’s something Windows and Mac users share, it’s the problem of uninstalling applications ““ and removing the debris left over.
Most uninstallers on Windows don’t remove everything, and often times they leave behind orphaned registry keys, file type associations, icons or even entire folders.
If Mac users have it easy, a simple drag and drop into the AppCleaner, there are lots of alternatives for Windows users which range from ‘the good, the bad and the ugly’.
I’ve found two that are – just nice.
Piriform CCleaner
Piriform CCleaner, available as freeware, scores high points all around with a simple interface and a complete set of features. CCleaner will:
- Search the computer and remove obsolete system files.
- Delete browser history, cookies and cache for all the major browsers.
- Search the registry for problems, back it up and fix it.
- Uninstall applications, rename and remove entries from “˜Add/Remove Applications’.
- Remove or disable start-up items.
- Automatically update itself if you allow it.
CCleaner is in my opinion, the best choice at the moment if you’re looking for an application to keep the cruft under control. I run CCleaner on my Windows XP SP3 machine almost weekly and every time I do, it removes at least 50MB of unnecessary files as well as a few registry keys.
Revo Uninstaller
Revo Uninstaller, although it has a more advanced uninstaller routine, comes in second because the interface is slightly clunky when compared to CCleaner. In addition to removing applications and cleaning the registry, Revo Uninstaller also has:
- “˜Browser Cleaner’ that removes traces of web surfing.
- “˜Microsoft Office Cleaner’ that clears the recent documents history.
- “˜Windows Cleaner’ that removes cache and history files from Explorer, such as Recent Documents.
- “˜Evidence Remover’ that overwrites free space to clean tracks of already deleted files and an “˜Unrecoverable Delete’.
The “˜Hunter Mode’, specific to Revo Uninstaller, enables you to choose the application you want to remove with the mouse ““ which is useful if the program you’re trying to remove doesn’t show up in the Add/Remove Programs list.
In order to write this article, I’ve also tested Absolute Uninstaller, Safarp, Perfect Uninstaller and MyUninstaller. I didn’t include these alternatives in the article because they’re not worth your time ““ either they’re worse than the integrated Windows application or they require you to upgrade to the so-called premium version.
Not impressed by either apps? At MakeUseOf, there’s always another choice. Check out these articles for other popular uninstallers and security apps:
