How to Clean a Startup Disk

You may have gotten a notification on your computer that the startup disk is full. Most PCs come with a disk cleanup feature that you can run to clean up the startup disk. Macs have automatic processes that keep the startup disk tidy, but further cleaning can be done by removing cached files and deleting old backups. Optimize your computer so it runs better by upgrading the drive or improving its memory.

Method 1
Running Disk Cleanup (PC)

1.Open the disk cleanup feature. Turn your computer on. Click the start button in the lower left corner of your desktop or press the [⊞ Win] button on your keyboard. This should bring up a search box. Type in “Disk Cleanup” and select this option from the list provided

2. Select the drives you want to clean, if necessary. When you select the “Disk Cleanup” function, a dialogue box will appear. In some cases there may be a drop-down box, in others there may be a list of drives you can select for cleanup. Select the C: drive from the drop-down box or list and select [OK]

* The C: drive is another name for the startup disk for most computers. Some computers may have other drives for backup purposes or other reasons. Disk cleanup can be used on any drive.

* Once you select a drive to clean up, your computer should analyze the drive. This process may take several minutes or longer.



3. Choose files for removal. When the Disk Cleanup has finished analyzing the drive, a new dialogue box should appear. This should list the suspected files that can be deleted without harming your computer. Select the boxes for file types (like Temporary Internet Files) that you’d like removed and press [Clean up System Files]or[OK]

* Some of the most typically wasteful file types include Temporary Internet Files, Temporary Files, Recycle Bin files, and Previous Windows Installations.

4. Delete the unnecessary files to clean the startup disk. After pressing[Clean up System Files]or[OK] you should receive a message verifying if you want to delete the files. Select[Delete Files]or[OK]to remove the files and clean the drive.

* If your computer is in need of a severe cleaning, this process might take up to 10 minutes or longer.



5. Delete excess iTunes backups on your computer. Open iTunes on your computer. In the top menu bar, click "Edit" and select "Preferences" from the drop-down menu. Click the "Devices" tab in the resulting menu. This tab will display backups. Highlight all backups but the most recent and click [Delete Backup].

* In some versions of iTunes, you may need to hold [Alt]  to bring up the top menu bar to access the "Edit" drop-down menu.

* Music libraries are usually quite large. Every unnecessary backup will decrease the memory available on your computer, slowing it down.

Method 2
Freeing up Startup Disk Space (Mac)

1. Remove unnecessary cached files. Access the Finder feature on the Dock of your desktop screen. In the Finder menu, click on the option labeled “Go to folder…” In the new dialogue box, enter “~/Library/Caches” and press enter. Delete large files or folders in the resulting cache folder.

* Further clean your startup disk by similarly clearing out your general cache. Access the general cache by searching Finder for the same library but without the tilde ( ~ ), as in “/Library/Caches”.

* The Finder feature is represented on Mac products by a face with one half colored dark blue and the other half light blue.

* Generally, cached files are safe to remove from your Mac. Not all files have to be removed. The largest files will have the biggest impact on the performance of your computer.

2. Dispose of unneeded localization files. Localization files support the use of languages other than the default for your computer. Open Finder on your computer and type “Applications” into the search box. Hold  Ctrland click one of the options in this folder. From the pop-up menu, select “Show Package Contents.” Delete any languages you don’t use.

* Removable language files are usually followed by the file extension “.lproj”. For example, Spanish would be expressed as “es.lproj”.


3. Clear out mail downloads. Open a Finder window. From its menu options, choose “Go” and then “Go to folder…” In the resulting window, type in “~/Library/Containers/com.apple.mail/Data/Library/Mail Downloads” to access email downloads saved to your computer. Delete all unnecessary files in this folder.

* Find email downloads more quickly by holding the  Command   key and pressing space. Enter “Mail Downloads” in the resulting dialogue box. Select the “Mail Downloads” folder and delete files as per usual.



4. Get rid of multiple iTunes backup libraries. Especially if your iTunes library is large, extra backups can take up a lot of space on your computer. Open Finder on your computer and click “Go” in its menu options. Select “Go to Folder...” and then enter “~/Music/iTunes/Previous iTunes Libraries”. Delete all backups except the most recent.

* Each of the backup libraries in the previous library folder will include a date for each backup entry.

5. Delete unimportant iOS backups. Whole system backups take up a considerable amount of space. Open Finder and access the “Go to Folder...” option by clicking “Go” in its menu options. Enter “~/Library/Application Support/MobileSync/Backup/” in the dialog box to display a complete list of backups. Keep your most recent backup, but remove the rest.

* Much like archived iTunes backup libraries, the date the iOS backups were created should also be clearly indicated along with the backup information.

Method 3
Optimizing Startup



1. Upgrade to a solid-state drive (SSD). If your computer doesn’t already have one, a SSD can greatly increase its speed. Inexpensive models for both PC and Mac computers can be found on websites like Newegg.com or Amazon.In some cases, replacing the hard drive of your computer may void its warranty.

* You may be able to preserve the warranty of your computer by having a certified technician for your computer install the new part.


2. Increase the memory of your computer. Generally, the more memory (RAM) your computer has, the better it will run. Be careful when choosing ram for your computer; different models will have different RAM requirements.

* Depending on the manufacturer of your computer and its warranty policy, upgrading the RAM may void its warranty.

* To check the RAM requirements of your computer, look up the support or component information for it. RAM specifications should be clearly listed along with this information.

* Some companies, like Apple, provide handy instructions and component guides for users who are interested in upgrading. Use these kinds of services to ensure you purchase the correct RAM and install it properly.


3. Reduce your startup applications. Startup applications can overwhelm your computer when you turn it on. This can bog it down and slow your startup times. Open “System Preferences” by selecting it from the list of options on your desktop Dock. In the following menu, choose “Users & Groups”. On the “Login Items” tab, you’ll find a list of startup apps. Remove all unnecessary programs from the list.

* When you highlight an entry in the list of startup apps, a minus sign ( – ) should appear. Select this to stop apps from starting when you boot up your computer

Android App Turns your Smartphone into a Simple Phone for Seniors

Your mobile phone is not a phone anymore, it’s a digital camera, a gaming console, a GPS navigation device, a music player, an e-book read, a file storage device, an alarm clock and lot’s more all rolled into one convenient device.

That said, some people do no need all the bells and whistles that are now part of every phone. For instance, You cannot imagine your grandma using my Android phone because the device is just too complicated for her. She doesn’t have any interest in the apps and all she needs is basic mobile phone that can do phone calls and text messages.

Some mobile companies do offer cell phones optimized for seniors but if you want the best of both worlds, just buy a regular Android phone and install Phonotto. This is a free app that will convert any Android “smartphone” into a “simple phone” hiding all the complexities and apps from the user. The following screenshots will give you a better idea.


Once installed, the app basically add a new layer on your Android phone giving quick access to essential phone functions while keeping all the apps in the background. The app’s interface uses large buttons with big fonts thus making the design more accessible to seniors.

The app can be configured to auto-start at boot time so it is always available. And while there’s little need to use the physical buttons on your phone, one can press the “Home” button to hide the Phonotto app and switch to your regular Android screen.

Take Good Photos with your Camera Phone



Digital cameras bundled with mobile phones are getting better and better with more megapixels, better quality lenses, storage space, resolution, focusing, video capabilities, facial recognition and flash.

That said, you don’t really need an high-end smartphone with a 8-megapixel camera to take good pictures. A decent camera phone with a 3-megapixel sensor is good enough for that everyday candid, lifestyle shots one tends to take.

The best camera is the one that’s with you.

While one cannot argue that smaller censor of the camera makes it difficult to produce sharp, noise free images, there are a few tricks one should learn while shooting with his/her phone camera phone.


TIPS – TAKING GOOD PICTURES WITH YOUR CAMERA PHONE

#1. Settings – As a photographer, I do not like shooting in the Auto mode of my DSLR as I do not want the camera to make decisions regarding how my picture should come out. Similarly for a camera phone if you have options of changing the settings try to change them as per your needs.

Turn off the flash when it is not required. I feel the bad quality of the flash ruins the photos most times and hence I do not like shooting with it and try to get additional light sources in and around the subject I am shooting. If you are shooting indoors and your camera phone has a setting for that then experiment with the setting first. Many camera phones have the option of changing the resolution of the pictures. Always shoot in the maximum resolution so you can capture the maximum details.

#2. Lights – Photography is all about Light, the one that lights up your heart. What is photography but play of light? Even while shooting with the camera, one needs to know how to read the available light looking at the conditions around. The best phone camera pictures are taken in plenty of light. Typically that is when one can try and reduce the noise levels and getter better results.

Different lights impact the color in your images in different manner. If your phone camera has the basic white balance features then experiment with them to get the near possible match. Be aware that your phone camera may not have the advanced features of a high end DSLR but a lot can also be fixed with touching up the images late. Most of the photos shot by the Blackberry have used light to its advantage; a couple were shot as backlits in extreme sunlight to bring out the translucent textures of the objects.

#3. Hold it steady – Do you often complain of blurry images while shooting with your phone camera? There is a possibility it has a slow shutter speed and is prone to blurs with a little shake here and there. Often there is a delay between the release of the shutter and the actual click of the phone. That is the moment when a little movement will create bad blurs.

Holding the camera really steady and even after the shutter is released, keep it steady for a few seconds more just to be sure. You could also try supporting the phone on a few books, table, against the table vase and get sharper images. Having said that, take advantage of the slow shutter speed and capture a couple of good motion blurs images. I usually make use of my HTC Tattoo’s slow shutter speed, which is a nuisance otherwise to create abstracts.

#4. Avoid zooming in –   The built-in zoom in most phone cameras are not optical but digital. Hence, it is advisable to not zoom in to compose a picture because you are not really zooming.

Fill up your frame by moving closer to the subject. This is to take care of the issue of subjects looking smaller than usual when shot on the phone which is due to the smaller resolution which is typical of phone cameras. Cropping could be a good solution to that but it can lead to pixilation.

#5. Experiment – Phone cameras allow greater flexibility in shooting. With their compact sizes, they can easily be tucked into that shirt pocket or that tiny clutch. Easy shots at any fashionable get-together or a wedding without carry a big DSLR and appearing clumsy. Experimenting with different angles, compositions is more possible since the device will fit into any nook or cranny and since a few camera phones have timers it makes it so much easier to get that elusive shot with a little planning.

Regardless of where I use it I do not miss, ‘missing the moment’ anymore since both my phone cameras given near perfect images whenever I want and depending on how I use them in those light/temperature conditions . These pictures can also be printed on an A4 size paper after proper post processing for optimum output.

Learn to Pronounce Difficult Words with YouTube Videos

If you don’t know the correct pronunciation of certain words or names and you are too embarrassed to ask, no worries as there are dozens of websites that can help you learn how to pronounce any word on your own.

The quickest option is Google. Use the define: search operator with any word and Google will show a little audio icon next to the word’s definition. Click the icon to listen to the audio pronunciation.

<a title="How to Pronounce Croissant" href="https://www.google.com/search?q=define%3Acroissant" target="_blank">define:croissant</a> [Google Dictionary Search]
The pronunciation feature in Google is however not available for non-English words or names of people but that is where YouTube videos can be of great help.

Let’s say we want to learn how to pronounce Eyjafjallajokull, the volcano that disrupted air travel across Europe in 2010 for several days. Here’s what you can do.

Go to YouTube.com and search for any word followed by “,cc” – this is a YouTube search operator that will only show videos that have closed captions.

<a title="Search YouTube Videos with Closed Captions" href="http://www.youtube.com/results?search_query=Eyjafjallajokull%2C+cc" target="_blank">Eyjafjallajokull, cc</a> [YouTube search for videos with closed captions]
In YouTube search results, pick a video that has that particular word in the transcript. Then click the transcript button and jump to the line containing that word (see screenshot).


You can now hear the speaker in the YouTube video using that word and that should give you a good idea of the correct pronunciation. And since YouTube has users around the globe, you can use the same closed-captions trick to learn how a word is pronounced in different countries of the world – just pick a different video from the search results.

Watch Videos on your Computer without Interruptions



When watching web videos or DVD movies on your computer, your video playback may be interrupted in many different ways.

For instance, the screen saver can activate itself or the computer screen may enter sleep mode if you don’t touch the mouse or the keyboard for a long period (because you are busy watching the video). Sometimes, pop-up notifications from IMs and other programs, that are running in the background, can also interrupt playback.

You can easily turn-off these distractions through Windows Settings but the problem with this approach is that the changes will stay even when you are done watching the video. To give you an example, if you disable the screensaver before hitting play, it will stay in the disabled state forever unless you re-enable it manually.

Therefore, instead of fiddling with your existing configuration, you may consider using utilities that will also disable all these distracting elements, but only temporarily.

Some media players are start enough and will automatically turn off the screen saver during video playback. If you are using VLC, go to Video settings and check the option that says “Disable screensaver.” In Windows Media Player, go to Player options and uncheck the box that says “Allow screen saver during playback.”

If your media player doesn’t have such a feature, you can use this excellent utility called Mouse Jiggler to prevent the screensaver from becoming active. It moves the mouse pointer back and forth periodically so Windows will never go into an idle state and therefore the screensaver won’t show up.

The next task is keep your monitor awake during the video playback. Mouse Jiggler should care of this part as well or you may try Caffeine – it’s like Jiggler but simulates keystrokes instead of mouse movements.

There’s nothing to install or configure – just download and run Caffeine and your system will stay awake as long as you like. Double-click the Caffeine icon in the task bar and it will disable itself – all this without making any changes to your system register or power plan.

If you have too many apps running on your system, they are consuming system resources and some of them, especially the chat clients, may surprise you during playback with notifications. You can either right click-click in the task bar to selectively close these apps or get a utility like CloseAll that will automatically close all running applications with a click.

CloseAll closes all running apps by default (including itself) but you can also configure it to ignore certain applications by adding a simple exclusion list to the CloseAll.exe command line. Here’s an example:

CloseAll.exe -x="explorer.exe|firefox.exe|outlook.exe|dropbox.exe"
An excellent alternative to CloseAll is SmartClose – it will not only close all the running programs with a click but can also restore all these the programs once you are done watching the video.

It does this by capturing a snapshot of all the running process and services. If there’s a particular program or Windows Service that you would not like the utility to close, just add it to the protected list. The default settings are good enough though you can always choose the location where these system snapshots should be stored.

Finally, if you like watching videos while simultaneously working on other windows /tasks, check out Always on Top – this is again a free utility that will help you stick your media player window on top of other program windows. Launch the program, select the media player window and press Alt+Space bar to put it on top.

Which DNS Server Should You Use On Your Computer?

The job of a DNS server is to translate domain names (like google.com) into IP addresses (like 209.85.135.103) and it does this for every new new site that you visit in the browser. Therefore, no matter how fast your Internet connection speed is, a site won’t load unless the DNS server has performed the lookup successfully.

When it comes to choosing a DNS server, you’ve several choices. There are public DNS services like OpenDNS and Google DNS or you could use the DNS Server of your ISP itself. To find your current DNS server, type ‘ipconfig /all’ at the command prompt and look for the “DNS Server” entry under Ethernet adapter.

The speed at which a DNS server can resolve domain names into IP addresses depends on its geographic location among other factors. Therefore, for example, OpenDNS could be the fastest performing DNS server for a user in location A but Google DNS could be a better choice for another user in location B. This also explains why your ISP’s DNS Server may perform faster in some cases.

Which DNS Server Should You Use On Your Computer?

If you would like to know which is the fastest DNS Server for your computer, there’s a free utility called DNS Benchmark that can help. It will test the speed of all the popular DNS Services, including OpenDNS and Google DNS, from your computer and then arranges them in the decreasing order of performance.

The bars represent the average time it takes for a DNS service to resolve web domain names into their equivalent IP addresses and thus, the lower the better. DNS Benchmark is Windows-only but Namebench is a good option if you are on Linux or Mac. For some reason, I could not get Namebench to work on Windows 7.

Most DNS services offer resolvers at two IP address – for instance, Google DNS is available at 8.8.8.8 and 8.8.4.4 – and they are used in the same order in which they are listed in your network settings.

You should therefore look at the performance of individual DNS servers and set the “Preferred DNS Server” as the one that has the lowest score. In fact, you may also mix servers – like you can use Google Public DNS as the Preferred DNS server and OpenDNS as your Alternate DNS server.

How to Remove Personal Information from your Digital Photos



This iconic Situation Room photograph, captured at the White House, has now been viewed more the 2.5 million times on the web. There’s little information available about the photograph but if you download the full-size version, you can get details about the camera model, the camera  settings and even the software that were used to edit this picture before it was published online.

This information is stored in every digital image, in the form of EXIF tags, and you can extract it using Windows Explorer or with the help of even the most basic image editing software. In the case of mobile phones, your pictures may even include location information thus giving others an idea of the exact geographic coordinates where that shot was taken.


HOW TO REMOVE CAMERA AND GPS DATA?

If you are planning to share your personal photographs over email or on a public website (like Tumblr), it may sometimes make sense to remove the camera data and the location information from the images before putting them online.

There’s a free Windows utility called QuickFix that can help you here. Simply drag-n-drop the photographs in the QuickFix window and click the Clean Metadata button to remove all identifiable information from the photographs. It creates a new copy and won’t overwrite your original photographs.

QuickFix will not only delete the EXIF data and the GPS location information from your photographs but also the IPTC and XMP tags that may have added by the photo editing application.

Microsoft also offers a free utility called Pro Photo Tools that you may use to edit as well as delete common metadata from digital photographs including the GPS location.

AN ALTERNATIVE WAY TO REMOVE EXIF INFORMATION

If the photographs are in one folder, you can easily remove the EXIF data from one or more of these photographs using Windows Explorer itself without requiring any additional software.

Select all the images files, right click and choose Properties. Now hit the Details tab and click on the “Remove Properties and Personal Information” link. The next screen will give you an option to remove the various metadata that is embedded inside the pictures. Simple.

Save Web Pages as PDFs Without Installing Extensions

While there are plenty of PDF writing software and online conversion services around that can help you save web pages as PDF files, the fact is that you don’t need any of them as long as you have Google Chrome on your computer.

Open any web page inside Google Chrome, press Ctrl+P (or Cmd+P if you are on a Mac) to open the Print dialog and change the destination printer to “Save as PDF.” Hit the Print button and the current web page will instantly download as a PDF document. Simple!



You neither have to install any software on your computer nor any extensions in your browser because Google Chrome itself acts as the PDF writer.

This is especially useful for downloading PDF copies of web pages that involve transactions or session data – like the checkout page on a shopping website – because you often cannot pass such pages to any online PDF conversion service.


One more thing. You can also use Chrome’s PDF engine to convert your local image files, text files and any local HTML web pages to PDFs – if you an open a file in Chrome, it can convert the file to PDF.

How to Open Files that have Unknown Extensions

Extensions, or the characters that precede the last period in a file name, help you determine the type of a file (is it an image, a video or something else) and you immediately know which software program is required to preview that file.

However, you may sometimes come across files that either have unknown extensions or don’t have any extension at all. How do you then determine the associated application that is required to open a file when you don’t recognize the file type itself?




RESEARCH UNKNOWN FILE EXTENSIONS WITH WOLFRAM

The first thing you are likely to do is “google” for the file extension but there is an easier open as well. Go to Wolfram Alpha and just search for the file extension with the dot (or period).
Wolfram won’t just reveal the technical details of that file extension – like the developer and MIME type – but also generates a list of software programs that you may use to open that file on your computer.

IDENTIFYING FILES THAT DON’T HAVE AN EXTENSION

If a file doesn’t have an extension, you can still identify the format of that file from its signature. All known file types have a standard and unique signature and this data is stored in the file itself. There are programs that can read this signature* and determine the file format even if the extension is missing from the file name.

The most popular program in the category of file identifiers is TrIDNet. First download and unzip the TrIDNet utility and the associated XML definition files in the same directory. Then open the TrIDNet.exe file, press the “Rescan Defs” button to load the file signatures (you only need to do this once) and then drag-drop any unknown files that you wish to analyze.

identify unknown files
It will show the different file types that match with the file’s signature and you can then use Wolfram Alpha again to learn about the different programs that can be used to open that particular file type. Do remember to rename the files after identification (press F2, prefix a dot with the extension).

[*] You can also determine the file signature of any known file format using Wolfram itself – use the query “<extension> file signature.”

How to Capture Videos of Google Earth

First please read the guidelines for using content from Google Earth and Google Maps:


[Offline use] If your proposed offline use of Google Maps or Google Earth is limited in scope, the concept of ‘fair use’ may apply

[Online use] You do not need permission to create and display video created from Google Maps or Google Earth in a video, whether hosted on your own site or through a service such as YouTube. You must purchase a copy of Google Earth Pro if exporting motion video, because screen capturing is not allowed.

If your usage meets the ‘fair use’ criteria, you can use the free Wegame client to record movies of Google Earth on your Windows machine. Wegame, a popular tool for recording video games, was recently updated and it now supports full-screen recording at 30 frames-per-second for smooth video.

Unlike most other screencasting software where you just hit the Record hotkey to start recording, it may take a couple of tries for you to get comfortable with the Wegame capture process.


Launch the Wegame client and connect with your online account – you don’t have to upload your movies online but you still need to login for the software to work.

Then launch Google Earth and you’ll see a green square box inside the Earth program. Hit F6 and the square should disappear meaning the animations are getting recorded. Hit F6 to stop the capture and the recorded video will get saved in your My Documents folder.

If you are recording Google Earth animations on a slow machine, try lowering the frame rate to 15 or 20 and also switch to Half-screen recording. The video is saved in Windows Media format that you can upload to YouTube or play in almost every media player.

Add a Green Screen Effect to Screencast Videos with Camtasia



Chroma key is a popular technique used in news rooms and films where the video editing software replaces the background of a video with a different scene which could either be a still image, an animation or even a video.

For instance, the news reader could be sitting in her television studio, in front of a green screen, but with Chroma keying, she can be virtually transported to any other location (like the White House).

Most video editing software including Adobe Premiere Pro, After Effects and Apple iMovie can help you add green-screen effects to your videos and so does the latest version of Camtasia for Mac.

Camtasia Studio, as most would know, is a screencasting software for Mac and the new version makes it relatively easy for screencast producers and presenters to add Chroma keying to their videos without additional software.

Navigate to the Video Effects tab and drop the Remove a Color effect to the video timeline. Select any color in the video to remove it. It helps if the background screen is green as the person standing in front of the screen is less likely to wear that color and thus the software can easily replace the green shades.

Camtasia for Mac is $99 per license though this upgrade will be free for existing Camtasia users according to the description of the YouTube video.

While you can easily construct a green screen background using either a piece of green cloth, sheets of paper, or you can paint the wall green but the more important thing is that your background should be evenly lit and that there should be no shadows on the screen as the chroma keying software may not detect them as green. There should be no wrinkles on the sheet either as they will difficult to remove in the final video as well.

Control Two Computers with a Single Keyboard and Mouse

Let’s say you have two computers on your desk and, in an effort to save space, you want to operate them using a single pair of keyboard and mouse.

There are two solutions here. If the computers are connected to the same network, you can use software programs like Input Director or Synergy to operate them with a common keyboard and mouse. In the other scenario where the machines aren’t connected, you can get a KVM switch to share one keyboard and mouse between them.


Check if the ISP is Limiting your Internet Download Speed

You have a fairly good Internet connection at home and regular websites load pretty quickly in your browser. However, the speed seems to go down while you are watching videos on YouTube or are trying to download files through a torrent client.

If you observe such a speed pattern quite frequently, chances are that your ISP could be rate limiting your traffic for certain bandwidth intensive operations. To give you an example, if your regular download speed is 100 kB/s, YouTube videos could be streaming at a speed of 30 kB/s due to rate limiting by the ISP.

Is your ISP is limiting your download speeds?


You can run the Glasnost test in your browser to determine whether or not your ISP is following any such tactic to manipulate your download speeds for specific sites.

The test uses a Java applet to compare your regular download speed against the speed at which Flash videos get streamed to your system. Other than videos, it can also compare the download speed for email attachments (via POP and IMAP), normal HTTP based file transfers, torrents and binary downloads from Usenet servers.


You should consider running these tests at different times of the day since some ISPs may be limiting speeds only during peak hours. Also, do remember to stop any other downloads that might be running in the background for more accurate results.


Boost your Wi-Fi Signal with a Can of Coke


A piece of Aluminum foil is probably the easiest and cheapest way to boost your Wi-Fi signal.

You just need to position the foil behind the antenna of your wireless router and the curved foil will then direct the Wi-Fi signals in your preferred direction thus boosting the overall signal strength.

Other than using an Aluminum foil, you may also make your own Wi-Fi extender at home using an empty can of beer or soda.

The cans are obviously more sturdy than the foil and the can’s lid acts as a stand but you need to be a bit more careful while cutting the can’s body with that knife. Also make sure that the can’s inner body is completely dry before you slip it into the router’s antenna.
