[MODIFIED] File Extensions – ZIP File Format

25 Aug

Zip archives defined, including how they are created and unpacked.

The .ZIP extension signifies that a file is a ZIP archive. This allows people to package a complete game, screensaver, application, electronic book, or whatever as one larger file instead of multiple smaller files, for example before sending them via e-mail. ZIP files are used often in Windows environments, and you will also see them on Mac and Un*x-based machines.

ZIP files can be created by a third-party external creation tool, but most modern operating systems have the ability to create basic .ZIP files internally without downloading such software. The process takes a group of files and mashes them (“zips” them) together into one “archive” file, sometimes reducing the amount of space the ZIP file takes on the hard drive (“compressing”). After the ZIP file is transferred, the recipient takes the ZIP file and “unzips” it, causing the original files to appear on their hard drive. Again, while third-party unzipping tools exist, most operating systems can do so directly….

Windows 7 – Don’t Like How Songs, Photos, Videos or Webpages are Opened?

22 Aug

Tired of webpages opening in a particular browser, or movies in an old multimedia player you no longer use? Change these associations in Windows 7.

When installing and uninstalling software on Windows 7, you may note that files that used to open in one program now pop up in other software. For example, install a new text editor or notepad replacement tool and you may notice that text files open up in said tool instead of Windows Notepad. Install a multimedia player and your songs and videos may not open in Windows Media Player anymore. Run a new web browser and your web pages may appear differently than how you remembered.

While many applications ask you before making such changes, you may accidentally gloss over such screens when installing them. Plus, some software may just make the changes for you. Thus, if you want to open files in different software packages, do the following:…

[MODIFIED] Search Engine – Why Did A Particular Site Appear in a Search?

12 Aug

A few reasons why a result from a search engine may not have anything to do with what you are looking for.

Ever perform a web page search, visit a resulting site, and find absolutely nothing on the page relevant to your search query?

First, use your browser’s find tool to search the page for the keyword(s) in question – press Ctrl+F, or Command+F if you are on a Macintosh. You should then be able to see if the page references your search word or phrase directly….

[MODIFIED] Buying a Digital Camera – What Does “Body Only” Mean?

07 Aug

When viewing digital camera listings for sale, why are some cameras listed as body only?

When comparing digital cameras and looking through sales ads, you may notice some cameras are listed with the phrase “body only”.

A “body only” camera means that the camera is most likely not a compact or prosumer camera but a higher-end digital SLR (single lens reflex) camera. Unlike other digital cameras, digital SLRs allow you to replace the lens, allowing for different degrees of wide-angle and telephoto shots (think skyline photos versus close-ups of birds high in trees). Plus, some lenses are ‘faster’ than others (ones with a larger aperture), allowing you to shoot even clearer photos in low-light conditions without necessarily using a stabilizing device such as a tripod (although these are always recommended when they can be used)….

[MODIFIED] Google Search Engine – Automatically Open Results in a New Tab or Window

02 Aug

Save time browsing Google results by opening websites in a new tab or window, keeping the search results visible.

As mentioned in a previous MalekTip, if you open Google results in a new browser tab or window, you can more easily return to your search results without having to use the “Back” button or re-enter your search query. However, this requires you remembering to manually do so every time. If you wish, you can have Google automatically perform this task for you:

(Note this tip was updated on 7/29/2012, and Google’s interface is subject to change.)…

[MODIFIED] Digital Fireworks Photography – Equipment Preparation Before the Shoot

01 Aug

Make sure your digital camera and accessories are ready to take plenty of great fireworks photos.

Preparation is the key to any successful digital photo shoot. Before you go out to a celebration to shoot photos of fireworks, whether it is the US Fourth of July, Boomsday on Labor Day, New Year’s Day, or other special occasion, make sure your equipment is ready:

* Obviously if it is legal and feasible (due to large crowds) to bring one along to where you are shooting photos, a tripod is crucial to getting the best, clearest photos. Otherwise you will need to hand-hold your digital camera very steady and do tricks such as increasing the ISO level to take quicker photos due to the low amount of available light. If you are using a dSLR, bring and attach any image stabilization lenses you may own to help offset the inevitable camera shake….

[MODIFIED] Digital Night Photography – Two Ways to Prevent Camera Shake

01 Aug

Your digital photos at nighttime need not be blurry if you use one of these techniques.

While most digital camera manuals describe the self-timer mode, where the camera takes a picture several seconds after the shutter speed is pressed, as “good for portraits”, the self-timer mode can be very useful for night photos as well.

Most night photos, especially in situations where you cannot reliably use flash, require a shutter speed of half a second or longer else the subject will be too dark. This is to compensate for the lack of available light. Unfortunately, these situations, especially if you are unable to use a tripod, can result in camera shake….
