Deticated to My Father : Perfect Dental Patient Unveiled at Showa University in Japan.

Those who had a chance to know more about the job of dentist, the fact that patients can be real trouble for dentists is probably familiar. It is especially hard to find a ‘perfect’ patient to be used in schools for training of new young dentists.

But, Japanese scientists from Showa University decided to create a ‘perfect patient’ which never complains and always obeys instructions. It is robotic patient called Hanako Showa and it will be used for dental treatment training.

I just hope they are not going to get used on perfect patient because in reality they will have to handle a very different kind of patients.

Windows Maintenance Tips: The Good, Bad, and Useless

Windows Maintenance Tips: The Good, Bad, and  Useless

Everybody's got an opinion on how to keep a Windows system running fast and smooth. Some tips are timeless, others are bunk that always recirculate. Here's a closer look at what really helps and hurts your Windows PC.

First up, here's the quick chart version, with the tips you're likely to hear floating around the net and from the mouths of casual IT types; each tip is plotted by its reputation and actual value. (More details for how we assigned these values below.) Click the image for a larger view.

Windows Maintenance Tips: The Good, Bad, and  Useless

And now a little finer explanation on those points.

Seems Bad, Is Good

Windows Maintenance Tips: The Good, Bad, and  Useless

These are those tips that seem like they actually kind of suck, but are in reality pretty good for your system.

Sleeping/Hibernating Instead of Shutting Down: Knowing that your laptop is drawing even just a trickle of power can freak out anyone who's had to pay for an expensive battery replacement, so a lot of people think it's always better to shut down your system when you're not using it. If we're talking PCs, the answer to the question of sleep or shutdown depends on how you feel about your electricity bill. For laptops, the issue of battery life and convenience is a sticky wicket. It takes some time and some vigorous hardware use to boot up your system, so if you know you're only stepping away from your system for, say, less than 3 hours, go ahead and close the lid and suspend it, or hibernate your system if you find it faster starting up. If you're going to be away for a solid bit, shut it down. Either way, don't plug it in if you don't have to, and spend more time getting things done than micro-managing your modern battery.

Windows Maintenance Tips: The Good, Bad, and  Useless

Windows Media Player: Windows Media Player used to be one of the first apps we'd replace on our system. Recently we learned to love the latest version of this built-in app, on the strengths of its performance (no, seriously), its built-in streaming and album art functions, and the fact that, now in its 12th edition, WMP is actually kind of good at what it's supposed to do.

Microsoft Security Essentials: Microsoft's security tools have never been that great—until they released Microsoft Security Essentials, that is. This anti-malware app is entirely free for Windows users, from initial install through every malware definition update. It's just as good at finding bad stuff as the leading commercial products, and it integrates well into your Windows system without adding a whole metric ton of toolbars, badged buttons, and other cruft. And if you follow some other basic security advice, you'll get by just fine, and never see a "reminder" that it's time to pony up for your protection fee.

Not having Windows "Ultimate": When you hear "ultimate", you can only assume it means "this version of Windows is a lot better". Early on, before Windows 7 was even released, Paul Thurrot did a little reverse-engineering of an early release and found that its main difference above "Professional" and cheaper versions was the inclusion of AppLocker, Federated Searches, and some virtual machine tools. Ed Bott summed it up succinctly: Windows 7 Ultimate, for all but the most corporate or IT-versed of users, is an "unnecessary luxury."

Windows Maintenance Tips: The Good, Bad, and  Useless

Not having "Admin" access: For the savvy user who does a lot of installing and tweaking, having Administrator privileges is just a means to an end. For users who are apt to click on "You've Just Won a Free iPad!", having administrator rights on their user account is a recipe for malware and other bad things. Granting admin access to bad stuff is the cause of up to 90 percent of security flaws, so on a shared desktkop, or a laptop you let your friends and family borrow, killing Administrator privileges might be worth the occasional verbal nagging.

Seems Good, Is Good

Windows Maintenance Tips: The Good, Bad, and  Useless
Let's call this the Advanced No-Duh section of system maintenance: Those tips that seem like a good idea, and they are. But they're also easy to lose sight of in pursuit of optimization, customization, and other tweaks.

Automating backup to external drive: Because protection from drops, spills, hard drive failure, electrical shorts, accidental deletions, theft, forgetfulness, and other calamities is clearly a good thing. Luckily it's not that hard to automatically back up your hard drive.

Windows Maintenance Tips: The Good, Bad, and  Useless

Automating backup to a web location: Because protection from fires, floods, acts of God or infants, external hard drive failure, and forgetfulness across two different safety mechanisms is the best thing. Luckily the best online backup tools are easy to use and relatively inexpensive (at least where your important data is at stake).

Install more RAM: Whether in your desktop PC, or skirting Apple Store prices and doing it yourself with a MacBook, adding more RAM can breathe a lot of new life into an old computer. Installing more than 4 GB may not always be worth it, or even feasible in some older systems, but it never hurts to future-proof your system.

Windows Maintenance Tips: The Good, Bad, and  Useless

Physically clean your system and peripherals: Dust, noisy fans, keyboard crud, and other symptoms of a well-used computer may not actually prevent you from doing work, but they do make using it much more annoying, and possibly less productive. Make your stuff look nicer, work better, and likely run more efficiently by giving it a spring cleaning.

Automating maintenance tools: Like a good backup, the tasks that keep your computer running clean and swift should be done without thinking. Whether it's a self-repairing hard drive, an automatic CCleaner run, or dozens of night-time fix-it jobs, it's not that hard, and the time invested in setting up pays off exponentially in having a worry-free Windows.

Using Revo Uninstaller: Because the Add/Uninstall Programs alternative Revo digs deep, moves fast, and just works. It cleans out cruft, shows you more of the apps you have installed than Windows does, offers auto-starting application disabling, and can even be pointed, sniper-style, at the application you want to kill but don't quite know the name of.

Seems Good, Is Bad

Windows Maintenance Tips: The Good, Bad, and  Useless
These are the deceptive tips that keep us tweaking our systems, often to our detriment.

Disabling QoS in Windows XP: Rumor had it that Microsoft had permanently tied up 20 percent of your net bandwidth for Windows Update. They didn't, and those who disable QoS, or IPv6, in XP actually end up with some pretty harsh connectivity problems.

Windows Maintenance Tips: The Good, Bad, and  Useless

Running defragment apps: On Windows Vista and 7, and into the future, the actual need for defragmenting hard drives is almost non-existent, since it's already done automatically. With solid-state drives, there's no need at all, and doing so might actually be harmful to the flash-memory-based devices. Defragging your drive won't likely cause any major harm, but for most of us, at best it's a wash.

Loading Internet Explorer with add-ons: Add-ons aren't necessarily a bad thing in themselves—they can, for instance, make IE act like Firefox. But if you're going to use Internet Explorer, and you're going to use add-ons, expect to see more crashing than normal.

RAM/memory optimizers: The fact that there was a federal investigation, and an article dubbing SoftRAM (and, by extension, its ilk) the "Worst Tech Product of All Time," should say it all. But, heck, let's just say it again. There are smart ways to manage your memory use, but you can't get something (more RAM) out of nothing (colorful packaging). Just because they no longer sell it in stores doesn't mean there aren't still software apps trying to convince you that the laws of physics don't apply inside your computer.

"Trick" Vista into multi-core booting: It's easy to assume Microsoft has done something wrong, isn't it? Like design an entire operating system, even one with a 64-bit version, that doesn't know how to use multiple cores. Heck, we briefly believed it, as did Gizmodo, but it's a sham. You can change how many cores Vista boots up with, but only if you're looking to test single-core operation for your application—otherwise, Vista automatically boots up with what you've got.

Enable SuperFetch in XP: In newer Windows systems, SuperFetch speeds up load times for programs and files. Trying to enable it in XP isn't actually harmful, unless you consider false hope a long-lasting harm. There is no SuperFetch in XP, no matter what Registry setting you tweak.

Clean out Windows prefetching: Another seemingly helpful tip we regret posting, as cleaning out Windows own log of which data to queue up on boot-up does, at best, nothing, and at worst can cause serious delays and problems with booting.

Windows Maintenance Tips: The Good, Bad, and  Useless

Reinstall Windows regularly: If you were never going to die, spending hours every year re-installing Windows—and, more relevant to most of us, all your applications and settings—would be a harmless move toward efficiency. In reality, though, you don't need to reinstall Windows unless something's gone wrong, because you can automate your backups and maintenance tools to keep it at an even speed and usability, year after year. And tell your Windows-hating geek friends we said so.

Registry "Cleaning": No doubt, the Windows Registry—where Windows keeps track of applications' needs, file associations, and other settings—is a big, unwieldy beast, and it's easily stuffed with leftover crud. If you're having a particular problem with a certain app, a Registry fix can possibly help. But stepping in every so often to "clean" the unnecessary stuff isn't going to speed things up, because Windows is mostly looking for the things it needs on each run, and doesn't, despite your worst fears, spend an entire afternoon browsing the Dead Sea Scrolls of your application installation history. Clean when you need to, but don't spend much time thinking about it.

Windows Maintenance Tips: The Good, Bad, and  Useless

Disable Shadow Copy or System Restore: Don't do this. You might think it's not necessary, and that you're the Ultimate Backup Maker, but doing so won't speed Windows up, you'll potentially cause problems with certain Windows services, and you'll never know when you'll need System Restore. The other night, I thought uninstalling Bonjour and Apple Application Support was a minor thing—until my Wi-Fi failed to work at all the next morning. Keep System Restore around.

Disable unneeded services: It's one of those nefarious "It depends" deals. There might be some services running on your system that you absolutely don't need, and Microsoft itself recommends checking them out. Just don't kill a service unless you know, specifically, what it provides you and your daily workflow.

Seems Bad, Is Bad

Many of these are downright laughable, but hey—we're just covering our bases here.

Windows Maintenance Tips: The Good, Bad, and  Useless

Installing lots of alpha apps: One or two early releases of software with a killer new feature? Yeah, sure, go ahead, but try to find a portable, non-install version, if you can. Always picking the alpha/pre-release/dev version of your favorite apps and installing them? It's like having a house made of 1,000 pipes, and you'll have no idea where that hissing leak you hear is coming from, or where it begins.

Type rm -rf / in Cygwin: Actually, any terminal command you see on the internet that someone suggests? If you don't know exactly what it does, and you don't understand the syntax, you're better off skipping it.

"Would you like to install the X toolbar to make searching easier?" Don't be that person—the one keeping Ask.com in business. Always watch during software installation to see what it's asking you to install and "make searching easier."

Drinking while Registry editing: Drinking while near a keyboard in general, really.

Uninstalling apps you don't recognize: As noted above, you might think your computer is cluttered with unnecessary applications, but it's often smarter to just let unnecessary apps age out, rather than find out a crucial network service was tied to a particular app.

Windows Maintenance Tips: The Good, Bad, and  Useless

Installing software from unverified torrents: Read the comments, think about the source, and run an MD5 checksum before installing anything from the public pool. Alternately: Don't install software from torrents.

Installing software from .ru sites: Would you rather spend 10 minutes finding a free, open-source alternative to what you're looking for, or an entire afternoon trying to recover files and restore your system?

Skipping updates from Adobe or Java: Even if it claims to be just bug fixes, and they feel like they arrive every day, install them, or un-install the product they're for, if you don't like them. It feels like giving in, but you don't want to be shaking your head sadly at a headline involving "exploit" tomorrow.

Universal Viewer - Open Almost Any Files !

Universal Viewer, as its name implies, aims to be a universal file viewer capable of opening almost any file, without making you hunt down required programs for unusual file types.

Universal Viewer supports a wide variety of multimedia, image, and document formats.While it supports opening a truly vast array of file types, it doesn't support Microsoft Office documents unless Office is already installed. Other than that, most files are supported without any special work on your part. Universal Viewer also has a navigation panel, which allows for easier file navigation.

In addition to the file viewing, Universal Viewer also supports additional plug-ins and can convert nearly any document type to friendly old plain text.

Here's a list of formats the app supports out-of-the-box :

Text, Binary, Hex, Unicode: any files, of unlimited size (even 4Gb+ sizes are allowed)
RTF, UTF-8: RTF and UTF-8 encoded texts
Image: all general graphics formats: BMP JPG GIF PNG TGA TIFF... plus all formats supported by IrfanView/XnView external viewers
Multimedia: all formats supported by MS Windows Media Player: AVI MPG WMV MP3...
Internet: all formats supported by MS Internet Explorer: HTML PDF XML MHT...
Plugins: all formats supported by Total Commander Lister plugins
MS Office: all file types of MS Office (if installed): DOC DOCX XLS PPT...
Converters: some types can be viewed as plain text: DOC DOCX PDF PPT ODT...

The application integrates into Windows Explorer's context menu, so all you need to do is right-click a file and select "Universal Viewer." In addition, it can also be integrated into other popular file managers. Universal Viewer is a freeware application for Windows platforms only. Got a similar tool you use to fill this need, or do you just hunt down and install whatever apps need installing when you need them?

Controling multiple Windows systems using the keyboard/mouse attached to one computer !

Some people use KVM’s to control multiple machines. These KVM’s are a simple switch that lets you switch control to another physically connected machine. A for the server, B for the desktop and C for your media center. This is OK but not the best setup.

Let’s say I want to copy information from my desktop to my server. I can remote desktop in, use VNC, AAMMY or any number of remote control programs. But what if I want to be able to view both machines at the same time? What if I want to use one keyboard and mouse for two computers.

If you have two or more machines in your home with monitors attached you can now control multiple computers from one single mouse and keyboard. It gets better because you can also share clipboards and wait, Input Director is FREE!.

input detector-control multiple computers with one keyboard

Input Director’s Website breaks it down like this:

`Before kicking off the installation and configuration of Input Director it’s important to first explain the master/slave terminology used throughout the documentation and application.

The master system is the computer that has the mouse/keyboard that you be using to control it and the other system(s). A slave system is one that can receive input (keyboard and mouse) from a master.

The quick start guide will run though setting up two computers, one as the master, the other as a slave. You need to decide now which computer you will use as the master – that is, which one has the keyboard/mouse that you want to use to control it and the other system (the slave).

For the remainder of the quick start guide, the two Windows systems that Input Director will be installed onto will be referred to as the master and the slave.`

Got it?

Your main machine with the keyboard and mouse that you want to use will be called the MASTER and other machines that you will remote control are your SLAVES.

This application is installed on each computer and you are give a bunch of security options like what computers can control your slave and neat hotkeys to make switching machines a breeze. You can setup a situation similar to multiple monitors with remote machines. You can move your mouse off your screen and right onto the next machine (basically, have multiple computers on one monitor). Even if you have multiple monitors this will still work.

I have used other programs that claim to do what Input Director does – but hands down this is the easiest to make work. It is really easy and if this fits a need that you have I highly recommend it!

Let’s take a look at it.

multiple computers on one monitor

You first run the setup on the master machine and simply set it as the master machine like seen here:

Then you setup the client machine. Come on back over to the Master machine and tell it where your Slave machine is.

You can now go and configure hotkeys and other goodies but that’s it. You are ready to manage multiple machines from one keyboard and mouse. Next step world domination!

Also, Synergy gives you the ability to manage all of your computers with just one keyboard and one mouse. When properly installed (and configured), you can move from one computer to the other by simply moving your mouse out of the computer screen. You’ll still need a different monitor for every computer, but switching between computers will be as easy as flicking the mouse in the right direction.

multiple computers one keyboard

Compare it to using 2 monitors on the same computer, where the second screen constantly displays an open VNC connection to your secondary computer. Screens can be arranged in any thinkable order; above, below or next each other. Synergy will also know the difference between two different systems and a dual monitor set-up.

Even unified screensavers and copy-pasting will work between computers !!

Use Incognito Mode to Keep Friends Logged in While Mooching Computer Time

History is used by the browser to enhance your experience on the Internet. When the browser remembers a website you previously visited or the username and password for your favorite web site, this information is considered your history.

However, there may be times when you do not want other users of your computer to see or access such information. For example, if a friend or family member shares your computer, you might prefer for them not to be able to see what websites you've visited or what files you've downloaded.

Also When you're borrowing time on a friend's computer it hardly seems polite to log them out of their favorite services. This clever trick let's you access popular services without having to make your friend log out and back in just to share their browser with you.

When using someone else's computer to check email/social networking, start private browsing (control+shift+p) in Firefox or incognito mode (control+shift+n) in Chrome, so you don't have to log them out from their Gmail or Facebook

It's an ideal fix for the problem. You get to log into all your accounts, you don't inconvenience the computer's owner by logging them out of any sites, and your own logins and browsing history aren't recorded

Firefox 3.5 and later provide "Private Browsing," which allows you to browse the Internet without Firefox saving any data about which sites and pages you have visited.

Note: Private Browsing prevents information from being recorded on your computer. It does not make you anonymous on the Internet.

What Private Browsing will not retain

  • Visited pages: No pages will be added to the list of sites in the History menu, the Library window's History list, or the Awesome Bar address list.
  • Form and Search Bar entries: Nothing you enter into text boxes on web pages or the Search bar will be saved for Form autocomplete.
  • Passwords: No passwords will be automatically filled in during the your Private Browsing session, and no new passwords will be saved.
  • Download List entries: No files you download will remain in the list in the Downloads window after you turn off Private Browsing.
  • Cookies: Cookies are file​s created ​by websites​ that​ store information ​on your​ computer​, such​ as your​ preferences ​when​ visiting​ a certain site​. These will​ not ​be stored. For more information on cookies, see Cookies.
  • Web cache files: No temporary Internet files or cached files from web pages will be saved until you turn off Private Browsing.
Note:
  • If you create new Bookmarks while using Private Browsing, they will not be removed when you stop Private Browsing.
  • If you save files to your computer while using Private Browsing, those files will not be deleted when you stop Private Browsing. However, any files you open in an external application will be cleared from the system's temporary folder, and none of the files you download will appear in the Downloads window list.

Turn on Private Browsing

To start a Private Browsing session:

  1. Click on the Tools menu and select Start Private Browsing.

  2. The first time you turn on Private Browsing, Firefox will alert you that it will save your current windows and tabs for after you finish using Private Browsing. Click on Start Private Browsing to continue.

    • Put a check mark next to "Do not show this message again" if you do not want to receive this alert the next time you turn on Private Browsing.
  3. You will then enter Private Browsing mode, and the Private Browsing information screen will appear.

When browsing in Private Browsing mode, the Firefox window's title will show (Private Browsing) during your session.

Turn off Private Browsing

Watch a video of these instructions

To end a Private Browsing session:

  1. Click on the Tools menu and select the Stop Private Browsing entry.

  2. The windows and tabs you were using when you enabled Private Browsing will appear, and you can use Firefox normally. The Firefox window's title will no longer show (Private Browsing) when Private Browsing is off.

Always start Firefox in a private browsing session

There is a setting in the Options window which will automatically enable Private Browsing whenever you start Firefox.

  1. At the top of the Firefox window, click on the Tools menu, and select Options....
  2. Select the Privacy panel.
  3. Set Firefox will: to Use custom settings for history.


  4. Click to select Automatically start Firefox in a private browsing session.

  5. Click OK to close the Options window

Who Owns The Most Servers

Google's Insane Number of Servers Visualized

Google's Insane Number of Servers  Visualized

You already just sort of know, logically and instinctively, that Google's got a ridiculous number of servers working for them. That doesn't make it any less mind-boggling when visualized. Get ready for a lot of scrolling.

Of course, not all servers are created equal—so "more" is a problematic word here. And I'm betting this wouldn't look quite so lopsided if big hitters like Microsoft, Yahoo, and Amazon were represented. Regardless, though, such a massive difference of scale is incredibly impressive, even if not entirely surprising.

Prevent unauthorized electronic fund transfers

Authentify released the ETF Verifier application which enables financial applications and payment platforms to alert legitimate account owners via phone whenever a new payee or funds transfer destination account is added to the user’s financial account.


This verification process permits the account owners to authorize a transaction or, more importantly, cancel a transaction if they are not behind the activity themselves. Adding new destination accounts has been the point of attack for the organized criminals behind ZeuS and its variants for getting cash from compromised accounts.

Keystroke loggers like ZeuS and Zbot capture everything a user may type on his or her keyboard including bank account numbers, passwords and other logon information. Even when an account is compromised, however, the trick is still getting funds out of the account. Electronic funds transfer via wire transfer or e-payment applications have become the vehicles of choice for criminals moving money out of a compromised account.

The final step is the addition of a new destination account number or new payee for an account controlled by the fraudsters.

ETF Verifier's process can be invoked whenever a new payee is added to an online payment or wire enaled account. The out-of-band authentication process sends an XML message to Authentify’s telephony service center. The message triggers a phone call to a telephone number on file for the account owner. A portion of the transaction details including payee identification is repeated audibly to the legitimate account owner over the phone. The account owner can then allow or cancel the transaction using their telephone keypad.

Microsoft Maren - Typing Arabic has never been this easy!

Lack of access to an Arabic keyboard or lack of familiarity with one are two of the most common problems preventing Arabic users from communicating in their own language.

Microsoft Maren is a Windows extension that comes to the rescue, allowing you to type Arabic in Roman characters (Romanized Arabic, Arabizi, Arabish or Franco-Arabic) and have it converted on the fly to Arabic script.


In Vista and Windows 7, you can also activate Maren using the default shortcut key (Ctrl+Alt+Space). Now, you can start typing in Romanized Arabic and as you type the tool will offer you the top 5 candidates for your entry. You can cycle through the candidates with the arrow keys or with the mouse, if you are not content with the top most candidate, you can click on the more button for additional candidates. If you don’t want to convert that last word you typed to Arabic, you can press the escape key or choose the English candidate (the top most candidate).

Kids Who Can't Even Read Recognize Logos For McDonald's, Disney And... Toyota?

A new study of brand recognition in kids shows that even kids who can't read can recognize corporate logos like Disney, McDonald's and randomly... Toyota.

The study, which involved 38 Australian preschool children ages 3 to nearly 5 years old, found that while the children were not yet able to read, they often knew exactly which logo corresponded with which brand. Certain logos -- including those for fast food chains (McDonald's), entertainment companies (Disney, the parent company of ABC News, and Warner Brothers) and cars (Toyota) -- proved especially recognizable. Others, including those for clothing (Nike) and personal care (Kleenex), fared considerably worse. (No children in the study recognized the Kleenex logo. Kleenex spokesman Joey Mooring said he was unfamiliar with the study but added that Kleenex's "primary consumer demographic" is "moms.")

The researchers were especially surprised to find children identifying brands whose marketing doesn't appear to target kids, including Toyota, which was recognized by 80 percent of the study's participants, and Shell, which was recognized by nearly 53 percent.

McAlister had a couple of theories to explain why brands like Shell and Toyota get kids' attention. For the former, children might associate trips to the gas station with stops for treats at a gas station convenience store, she said. For the latter, children may recognize car brands because they've learned to distinguish between their parents' cars and those of others.

Travel Packing Tips

I have just got an email from a fantastic friend called Bassi - the email subject was "Travel Packing Tips" - So, I preferred to copy/paste her words here in my blog :

Here are some packing tips that you might use during your travels this summer (well whenever you're traveling basically!:))


1.Don't pack more than you can carry
Even if you can afford porters they will not always be available.

2.Write a list of everything you want to take.
Lay it all out on a bed before you start packing so you can see how much you want to squeeze into your case.

3.Take out at least a 1/3 of the clothing.
You'll never wear as much as you think you will. Laundry services are available everywhere.

4.Take out the iron and hairdryer
Hotels always have them available to borrow and besides, a holiday is too short for ironing!

5.Don't pack valuables in your main luggage.
Jewellery, medication, camera and documents should be packed in your hand luggage.

6.Carry a daysack or holdall as your handluggage
Many airlines will only allow 1 piece of handlugge, a smaller handbag can be placed inside this bag

7.Roll your clothes or fold like shops do to reduce creases

8.Wrap any fragile items amongst your clothes in a plastic bag

9.Stuff your shoes with underwear so they keep their shape

10.Vacuum bags are very useful for reducing volume
Although don't use them for your clothes on the outward journey or you'll be wearing a bag of creases!

incredible, isn't it ? :)

Understanding Your Digital Camera's Histogram

Digital photography provides us with a variety of tools to help make better photos. Unlike the old film days, we now have ways to review how well exposed or metered our shots are before actually printing them.

Most photographers contend with reviewing images on the back of the LCD screen to assess how well exposed they are. But because the LCD screens can be rather small and well illuminated, they can make photos appear better than what they actually look like on much larger computer screens.

Furthermore, sometimes viewing photos on the camera’s LCD screen might not show a loss of detail in the shadows or dark areas of an image, nor in the white or bright areas. When we’re really concerned about getting the best exposure for our photos, we might use the camera’s zoom-in feature to assess exposure and sharpness of our images. Additionally, we could use the Histogram tool of both our digital camera and image editor to see how well exposed our images are.
To some novice shooters, the Histogram may look like something a technician would use to see if your camera’s functioning properly. While the Histogram feature can be found in all 35mm digital cameras, the tool might not be easily visible; with some cameras you may have to push a button or two to bring it up. But that’s okay, once you learn how to interpret the Histogram, you might find it worth accessing and using a regular basis.

For this tutorial we’re going to primarily in Photoshop to understand how it works. The Histogram in a digital camera works nearly the same way it does in an image editor like Photoshop, so this tutorial also details how to read camera histogram.

What is the Histogram?

The Histogram is basically a graph showing the brightness distribution of an image with pure black on one end, pure white on the other and grey in the middle. Because measuring light is what photography is about, the Histogram works pretty well in a digital camera, but it also may be a little confusing, so I’ll try to clarify with a few image examples.

LIGHT RANGE

A digital camera sensor can only record a certain range of light values. Remember how with film the light range was limited to only a few f/stops of range? With transparency film the limitation was about 3 or 4 "stops" of light, while with negative film it could go on out to 5 or 6 stops. Today's digital sensors seem to be able to record about 5 or so usable stops of light. Most will agree that the digital camera can record a little more than transparency film, and a little less than negative film. This will change, since some digital cameras are now offering extended range sensors.

Unfortunately, many of the higher contrast subjects we shoot can contain over 12-stops of light values. This is quite a bit more than it is possible to capture with film or a digital sensor today. It is important to understand how your digital camera records light, so that you can better control how the image is captured.

Look at Figure 1 below. The gray rectangular area is a representation of an in-camera histogram. Examine it carefully! Think about it for a minute before reading on.

The histogram basically is a graph that represents the maximum range of light values your camera can capture, in 256 steps. (0 = Pure Black, and 255 = Pure White) In the middle of the histogram are the mid-range values that represent middle colors like grays, light browns, and greens. The values from just above zero and just below 255 contain detail.

The actual histogram graph looks like a mountain peak, or a series of peaks. The more of a particular color, the taller the peak. In some cases the graph will be rounder on top, or flattened. The left side of the histogram represents the maximum dark values that your camera can record. The right side represents the maximum white values your camera can capture. On either end of the histogram the light values contain no detail. They are either completely black, or completely white. The top of the histogram (top of mountain peak) represents the number of different colors, a value you cannot control, so it is for your information only. We are mostly concerned with the left and right side values of the histogram, since we do have much control over those. (Dark vs. Light)

So, basically, the histogram's left to right directions are related to the darkness and lightness of the image, while the up and down directions of the histogram (valleys and peaks) have to do with color information. I repeated this for emphasis! The left (dark) to right (light) directions are VERY important for your image making. If the image is too dark, the histogram will show that by clipping off the light values on the left, or, if too light, by clipping on the right. This will become easier to understand as we look at well exposed and poorly exposed images.

Over-exposed Images

Many images we capture might tend to be over or under-exposed. It’s easy to tell when a shot is way overexposed because most of the detail in the image in blown out. In scenic images, a loss of detail often occurs with clouds and the sky in the background, such as with photo below. If you expose for the buildings, the background sky gets overexposed.

In the Histogram, the graph shows a bias to the right end. When the graph is bunched up against the right side (pure white), it indicates the areas of the image that are overexposed, or clipped—a technical term meaning a loss of detail or information in an image.

Underexposed Images

When the Histogram is bunched up toward the left (pure black), it indicates that areas of the photo are underexposed, and that details are clipped in dark and shadow areas.

Balanced Image

A more balance Histogram depicts a graph with the pixel representations spread across the graph and tapering off on both ends, such as in this image.

However, it’s often difficult to achieve a balanced graph for most photos. Significant contrast in the light, dark, and mid-tones in the foreground and background areas of a photo typically makes it difficult to get a balanced exposure.

In the first photo example above, it’s nearly impossible to expose for both the background and the foreground of the image. So one solution is to meter for the sky, which means under-exposing the photo to capture the details of the sky, and then open up the shadow areas of the foreground in an image editor.

Sometimes the Histogram may show exposure clippings that are not a particular problem in the photo. In the image below, the graphs depicts a bright spot in the corner of the photo and some loss of detail in the dark areas of the flowers. But these are not major problems for this image. The details in the foreground are pretty much where you want them to be.

By the same token, in this photo below, the light on the subjects was even, and the Histogram depicts an exposure with no clippings. And because the graph is spread out and not bunched up in the middle, it indicates that the photo also includes a nice contrast.

Again, the Histogram results don’t have to be perfect, but when you see clippings on either side of the graph, you will want to review your images to see if there’s a loss of detail in important areas of the image. The Histogram is also useful when it’s difficult to review your photos such as in bright sunlight on the LCD screen. The Histogram can give you pretty good indication about the accuracy of your exposure.

Manage & Share All Your Firefox Add-Ons With The Add-On Collector

When was the last time you dived into your Firefox menu to check the number of add-ons you have installed? I bet we don’t do that often unless we need to tick off an option or get one uninstalled. The convenience of Firefox add-ons makes installing and forgetting about them equally easy. Especially if we have lots of them.

But for the serious Firefox guy, managing add-ons is as serious an activity as say, tweaking the browser under the hood or choosing just the right theme to go with the day’s mood.

The latest management tool for handling all those add-ons goes by the name of the Firefox Add-on Collector.

With the mindboggling variety on offer, the Firefox power user would want a tool to manage Firefox addons. One way of course, is to make a daily visit to the Mozilla Add-ons gallery and check up on the latest. The more convenient way is to use a meta-extension that does it for you.

The Firefox Add-on Collector is about four things –

  • Managing your collections and creating your own from within Firefox.
  • Staying updated of any changes in the collections.
  • Sharing your collections with friends.
  • Synchronizing collections across your computers.

Let’s see how these four attributes come together in this master add-on.

The Firefox Add-on Collector installs just like a usual add-on and can be accessed from Tools – Add-ons. You will need your Mozilla account or get yourself registered with a new one.

manage Firefox addons

As you step into the gallery with a log-in, you can browse and choose collections to add. Adding collections is simple with a click on the Favorites button.

The Add-on Collector captures all your collections and lists them as subscriptions. With subscriptions, it’s a cinch to stay updated with any change in the collections. For instance, any addition to the collection is notified via an alert.

The Add-on Collector Settings lets you customize a few of the features like update intervals and the option of receiving notifications.

Nothing remarkable so far. But the Add-on Collector also allows you to manage and share your Firefox add-ons with your friends with an email. You can share any add-on with a click on Publish to – Email Address.

The same menu also lets you build your own collections by publishing add-ons to a new collection.

The Add-on Collector comes into real use if you have multiple computers setup with Firefox and a gallery of add-ons to keep track of. Using the Auto-Publisher feature, you can keep your add-ons synchronized across all your computers.

Create an auto-publisher entry with one computer, and it will appear at the top of your subscriptions list on all of the computers that have the Add-on Collector installed. You’ll then be able to see add-ons installed on each computer that has an auto-publisher set up.

Install or uninstall add-ons and its gets auto-updated across computers. Auto-Publisher also works similarly between user profiles on the same computer.

Add-ons help to stretch Firefox to its full potential as a browser. But the large number of add-ons can also easily entangle you if you are not careful about your add-on picks. The Add-on collector makes it slightly easier to manage them and adds a lot more to the job of keeping them updated and synchronized.

How To Optimize Your Windows Trackpad With Scrybe.

There are two things that you can do to be more productive in using a computer: improving yourself as the user, and improving the computer itself – either by upgrading the hardware or by using additional applications to enhance the hardware.

For laptop users, the Windows trackpad is one of the vital components that will determine the quality of your computer using experience. That’s why Apple put so much attention in improving their trackpad’s usability. But the story is a little bit different in the land of Windows. Most non-Apple notebooks don’t come with multi-touch gestures feature. You need third-party applications to enable it (and the applications might not work with every hardware).

This app is called Scrybe and it’s coming from Synaptic – the hardware maker of trackpads used by most Windows notebooks.

Starting Out With Scrybe

Scrybe is the application that will enable two-finger scroll – and more – in most non-Apple notebooks. Before you can download this app, you have to register first. The installation is also not straight to the point; you will be asked to upgrade the recent Synaptic driver on your computer with the latest version before Scrybe can be installed (and to avoid conflict, you might want to disable other Windows trackpad modification apps before installing Scrybe.)

Then after all the hoops, you will find your installations sitting quietly in the taskbar.

Installing this app will give you the ability to do two finger scrolling – up and down and also left and right the pages. To adjust the speed of the scrolling, right-click the trackpad icon on the Taskbar and choose “Pointing Device Properties“.

Go to the “Wheel” tab and set “The following number of lines at a time” to your preferences. For me, the most comfortable setting is the lowest number available: 1.

Scribbling With Scrybe

But two finger scrolling is not the only thing that you will get from Scrybe. This app allows you to quickly open applications or go to an URL just by doing the “Three-finger tap” and then scribbling on the trackpad.

Scrybe comes with a great number of pre-set gestures, but you can add more according to your needs. Right-click the Scrybe icon on the Taskbar and choose “Scrybe Control Panel“.

03a_Scrybe_Control_Panel.png

The Control Panel window will open. Click on the green “Plus” sign (+).

This time, the “New Gesture” window will open. Give a name to this new gesture that you are about to create, choose what type of gesture it is (“Visit Website” or “Launch Application“), and set the action. If you choose “Visit Website“, you have to write down the address of the site, but if you choose “Launch Application“, you have to tell Scrybe the location of the app.

Before clicking the “OK” button to create the new gesture, you have to select one symbol to represent the action. Click on the small arrow below the blue “Symbol” box and choose one from the many available symbols.

03d_Select_a_Symbol.png

There are enough symbols available to represent any action that a normal people could think of, but it would be better if users are allowed to create their own symbols.

After you create the new gesture, it will appear on the “Favorites” tab. Rinse and repeat the process to create more actions.

The default search engine used by Scrybe is Google. If you want to change this into something else, click the “Preferences” button. The Scrybe Preferences window is the place to customize the search engine – and a few other little things.

04_Scrybe_Preferences.png

Now is the time to see Scrybe in action. Tap three of your fingers on the trackpad and the input display will appear along with hints to several popular gestures.

05_Three_Finger_Tap.png

Draw the gestures on the trackpad, and the action will be performed the moment you pull your finger off the trackpad. If the action is successful, you will see a confirmation window popping out from the Taskbar.

For the list of available gestures, you can click the “Gesture List” button from the “Scrybe Control Panel” window. The list will be opened in the default browser.

Several Afterthoughts

After playing around with Scrybe for a while with the Windows trackpad, I personally think that this app could boost productivity in using a non-Apple notebook.

Please note that this app might not work for some models. And being the product of Synaptic, I guess Scrybe would work best using Synaptic hardware (but I can’t confirm that since I tried the app using only one notebook).

If you are using a notebook yourself, why don’t you try the app and share your findings using the comments below.
