How to identify flags of the world?

If you recognize each and every flag of the world, it’s commendable. But not everybody has such a keen memory. Often we come across flags we have never seen before and we get stumped. If you find yourself in such a fix, head to Flag Identifier.

Flag Identifier is a web site that helps you identify different flags of the world – national flags of countries, military flags, civil flags and so on through their flag search engine. Using the engine you can search flags by color, shape, geography, history, objects and so on. I decided to give it a try.

I started looking for a flag that is complex - had many colors and had some kind of an emblem or shape and finally settled on the flag of Commonwealth of Dominica. I’m going to try and search this flag out.

flag_dominica

I went to Flag Identifier and selected search by color and device combined. Next I selected the four primary colors on the flag – red, yellow, green and black, one at a time. As I kept selecting the colors I saw that the available colors began to narrow down – the search engine had already began to filter the results. At this point it gave me to choose two more colors – blue and white, which is exactly the two remaining colors on the flag.

flag_identifier1

Next I selected a device, an animal and then selected bird in the following step. When I proceeded to the next step and saw a parrot waiting for me, I knew they had found it.

flag_identifier2

I completed the remaining steps and ta-da, here is the result.

flag_identifier3

The entire process took less than 2 minutes. The search process is so easy and the search engine so perfect I know I could find any flag with it. And if you make any mistake when choosing colors or shapes, just hit the back button of your browser and correct your mistake.

At the time of writing this, Flag Identifier has 1026 flags in the database. This is certainly worth a bookmark.

Doculicious - Fillable PDF documents for your website

Doculicious is an interesting web service that allows webmasters to create fillable PDF documents and then embed those on their website. It’s just another way of creating web forms to collect information from your visitors or customers, but there is one certain advantage. It allows the user to download the completed form as a PDF file that can be saved on their computer or printed, while the entered data goes to the webmaster. Doculicious can also be used in places which has nothing to do with data collection. For instance, you can create templates of certificates for schools or visiting cards for employees of an organization. The users fill the required data and download the PDF copy for printing.

Doculicious is available in free as well as paid plans. The free plans has limitations on the number of documents you can create, number of times these can be filled and downloaded, the storage space you get and some other features.

Doculicious-editor

You will need some time to get used to their document editor, but once you do it’s pretty straightforward. You can create a new document from scratch or import an existing template and then modify it. The document can be customized in every possible way – document size, background color, text size, font and color, add image, resize them and drag and drop elements to position them on the canvas. The behavior of each element can be further customized using the Element Properties box on the left side of the document editor.

If you are collecting information you can receive notification every time somebody uses the document. You can also choose not to collect any of the entered data.

Here is an example fillable PDF document I have created (pardon the crooked look). This document does not collect any information you enter. So feel free to try it out. The free account is unfortunately limited to only 50 entries and 20 downloads per month.

MediaPortal – The open source alternative to Windows Media Center

The Windows XP Media Center Edition, as you already know, is designed to transform your computer into a complete entertainment hub. There are a few alternatives to it such as Beyond TV, Tivo and WinDVR which are commercial software and some free ones like MythTV and Freevo. The problem with the free alternatives is that these run on Linux and most people get scared away by the very mention of the name Linux. MediaPortal is another free media center software that runs on Windows.

MediaPortal allows you to watch videos, view TV guide for various channels, record, pause and rewind live television like any PVR software. You can listen to music, streaming music from various Internet radio stations, monitor weather, play games and browse pictures, burn DVDS and more. And if that’s not enough, MediaPortal has an extensive collection of plugins allowing users to extend the functionality of the software even more.

UltraStar – The game that judges how well you sing

Want to know how people on the other side of the bathroom door react when you sing? Do you want to find out if your voice is gifted enough to let you fulfill your secret desire to publish your own music album? Sing in front of UltraStar and let it judge you.

UltraStar is a clone of the popular karaoke game series for Playstation - SingStar, released under GPL for Microsoft Windows. Like the original game, UltraStar require players to sing along with the music or a music video, like in a karaoke system, in order to score points. The game displays the lyrics as well as the correct notes in the form of horizontal bars. On top of the correct notes UltraStar displays the pitch recorded from the players. The game analyses the player's pitch and compares it to the original track, and then scores the players based on how accurate their singing is. Ultrastar allows several people (up to 6) to play simultaneously by connecting several microphones, making it an ideal game for parties.

 ultrastar

The game comes pre loaded with just one song from Nine Inch Nail, obviously due to copyright issues. But you cannot simply add any song from your music library to this program. Only songs that are specially packaged for use with UltraStar can be imported into the program. Don’t worry, there are thousands of such songs available on the Internet. UltraStar Songs is one destination. Then there are torrents, or simply search for “UltraStar songs” on Google.

The game also has a music creation utility using which you can create your own music packs, but this involves a fair amount of work. A better way is to just download them from the Internet.

Ultrastar_deluxe

The UltraStar project has forked into several similar game projects, many of which are better than the original game. UltraStar Deluxe is one such fork. While the original game works only in Windows,  UltraStar Deluxe is available for all the three major platforms – Windows, Linux and Mac. UltraStar Deluxe is also significantly better than it’s parent.

  • It has support for more video formats, such as DivX, XviD, FLV, Avi and WMV.
  • Many visual improvements
  • It has a Party mode with various game types. This includes support for plugins that allow further extension of such game types.
  • Improved song management and selection with the ability to search for songs and use playlists
  • More detailed statistics screen

Performous is another deviation from UltraStar. This one is entirely devoted to the Lunux platform though it can be installed on the Mac too. It has it’s own peer developer group leading to several new improvements and unique features. Performous has better pitch detection capabilities as it uses FFT (Fast Fourier Transform) that can detect multiple tones simultaneously, compared to Autocorrelation which is used by UltraStar. Another unique feature to Performous is that it draws the singing pitch as a line on the screen, allowing the player to easily spot their mistake and correct their pitch.

Performous

There is yet another fork to UltraStar, the UltraStar for Mac OS X.

And UltraStar isn’t the only karaoke game available. Take a look at these competitors – Sinatra, Canta and KaraokeParty.

Send your name to Mars

Do you know that NASA is sending another rover called the Mars Science Laboratory Rover to Mars on 2011? Do you know that you can send your name on it to Mars?

NASA has always been very conscious about their public image and why not? After all they are burn 17 billion dollars at the tail end of rockets each year, and the budget is steadily climbing. Even during this economic turmoil, NASA’s budget has remained literally untouched. Don’t get me wrong, I’m a huge supporter of the space program and would love to see newer, more advanced and bigger projects from NASA. But the U.S taxpayers aren’t going to take this in stride so easily. NASA  needs to generate public support and convince them that whatever they are doing is for the greater good of humanity. A good way to get support is to get people involved.

So they came up with a multiplayer game, live videos from the space station, public polls to name the Mars rover and now Send your name to Mars - an essentially pointless thing but enough to get people excited.

Mars_rover

Simply submit your name and it will be put on a microchip on the Mars Science Laboratory rover and sent off to Mars on 2011. What will happen after that? Nothing. Your name, nothing more than a bundle of ones and zeroes, will stay on the chip, along with the names of thousands of others who have done the same. No Martian is ever going to read that chip either. But that hasn’t discouraged the 12,000 odd people from putting their name on the chip, including me :)

So go ahead and submit your name, you have nothing to lose. You will even get a certificate from NASA for doing it.

KidRocket - Web browser and desktop protection for kids

Probably the most scariest thing for parents is to leave their child on the Internet unattended. But who has the time to monitor everything a child does on the computer or prepare a blacklist of millions of objectionable websites to add to the host file? It’s impossible. If you are facing a similar predicament take a look at KidRocket.

KidRocket is a simple web browser targeted towards kids. Actually, it doesn’t entirely fit the description of a web browser, it’s more like a package with a number of application for kids which also includes a browser. KidRocket’s browser allows the user to view only a handful of kid specific websites included in the browser’s whitelist. Currently the list consist of only 12 websites which includes some popular kid sites like Nick.com, CartoonNetwork.com, PbsKids.org etc. These websites appear as row of thumbnails at the top of the browser and can be opened by clicking on it. The browser has no visible address bar where you can type a URL, so it’s impossible to open any other websites not included in the browser.

kidrocket-main

KidRocket also has an Art tool and a Math application. The Art tool is a simple drawing program for kids with over sized paint brushes and bright colors. The Math tool gives the kid simple math problems to solve, the difficulty of which can be adjusted by the parents from the Admin tool.

In case you are wondering what an art and math tool doing in a browser, there is a good reason. KidRocket also functions as a desktop locking tool. After launching the application, parents can lock KidRocket in place with a password. The application goes full screen and without the correct password the kid cannot exit it to access other items on the computer. This means that once the application is locked with a password the kid cannot open a regular browser to view other websites, or play games or watch movies. Even Ctrl+Alt+Del doesn’t work.

So parents can effectively lock down the computer leaving only KidRocket open with a browser, an art tool and a math quiz. It’s a great tool for working parents.

The only drawback of KidRocket is the inability to add more sites to the browser. Kids get stuck with only 12 websites. There are hundreds of more sites for kids which are not included in the browser. Sure those 12 included sites are regularly updated and provide plenty of games, but sooner or later kids will get tired of it.

8 browser addons and scripts for better YouTube experience

If you spend a considerable part of your life watching YouTube videos, you would appreciate me for compiling this list for you. Remember that you will either require Firefox or a browsers that supports userscripts, like Opera and Safari, to use these tools. So here we go.

youtube_logo2

Removing distractions from YouTube page

Quietube: This is the most recent of all YouTube tools, so let me mention this first. Quietube is a browser bookmarklet that removes all distraction from the YouTube page which includes comments, advertisements and well … everything, except the video. Just drag this bookmarklet to your browser’s bookmark toolbar and whenever you land on a YouTube page, click on the bookmarklet to quickly wipe out everything from the page. Want to share the video with someone? Click on the Tinyurl link at the bottom of the page to automatically create a Tinyurl shortened URL for sharing.

YouTube Comment Snob: YouTube comments are worthless, we know it. But still if you don’t like the idea of removing all comments from YouTube, then you can try this Firefox addon. YouTube Comment Snob allows you to filter out trashy comments based on customizable rules like spelling mistakes, excessive punctuation (!!!! ????), excessive capitalization, profanity and such.

Video Focus is another distraction free tool, this time in a Greasemonkey script format. The script allows you to turn on or off comments, related videos, and also allows you to resize the browser to fit the video, change background color and also download videos. Video Focus supports more than 70 video sites.

Preventing AutoPlay of videos

TubeStop is a Firefox addon that prevents autoplay of YouTube videos. Useful when you open a number of YouTube tabs at the same time intending to view them one after the other. For non Firefox users there is a userscript YouTube Prevent Autoplay. Of course, you can use it with Firefox too.

HQ YouTube videos

YouTube HQ + 720p Ultimate is a Greasemonkey script that automatically switches all YouTube videos to high-quality, if it’s available. It ensures that you always get to view a video in it’s highest available resolution without having to seek for it yourself. This script also comes with the autoplay off feature.

Create album cover mosaic wallpapers with Last.fm Desktop Generator

Gijsco's Last.fm Desktop Generator is a cool application for music junkies. Here is what it does: it downloads data from your Last.fm profile and then creates a mosaic out of the covers of your favorite music albums and sets it as a wallpaper.

Actually, this program is capable of pulling music history data from any Last.fm user. Just enter a Last.fm username, click on Draw Image and create a mosaic of album covers. The mosaic can be saved as a single image for later use or directly applied as a wallpaper. The data source can either be the most recent albums a user listened to during the past week, month, 3 months, 6 month, a year are the overall music history of that user.

lastfm-desktop-generator

The program offers a surprising number of customization options despite it’s simple function. The options menu is neatly categorized into 3 sections – Pre-processing, Drawing and Post-processing.

lastfm-options The Pre-processing options allows you to filter the data which is retrieved from the Last.fm. For instance, you can choose to include certain albums into the result or exclude them, or use only those albums that were played for a specific number of times. You can also ‘boost the quality’ of the album cover images by instructing them to download higher resolution images.

The Drawing options enables you to add borders to the images or even include your own fake album covers. There are more drawing options under the Draw Image menu like generating mosaics with same album cover size, or random sizes or a single line of images with reflection and glassy effect.

The Post-processing options provides a handful of image filters like blur, desaturate and fade. The various options enables you to apply all kinds of effects and modification without having to import the image to another image editor.

A number of available command line switches enables you to create a schedule task to automatically generate a new wallpaper at any interval you desire.

How to spot the International Space Station, now the 2nd brightest object in the night sky

There has been a buzz of activity around the International Space Station for past several days and it culminated last Friday with the successful deployment of a new set of massive solar arrays. The new solar panels are so huge that the sunlight reflected from these arrays makes the ISS easier to spot with the naked eye than ever before. It is now the second brightest object in the night sky, even brighter than Venus and beaten only by the Moon!

Astronauts on board the ISS and space shuttle Discovery unfurled the arrays, successfully carrying out the main objective of the STS-119 mission. "Today was a great day," said ISS commander Mike Fincke to mission control Friday afternoon. "Today is the day the station went to full power." The length of the arrays unfurled Friday measures 73 meters (240 feet), tip to tip, with the S6 truss in between. The S6 solar array pair adds 892 square meters (9,600 square feet) to the station solar arrays, bringing the total surface area to nearly an acre. The station’s arrays now will generate as much as 120 kilowatts of usable electricity, enough to power about 42, 260 square meter (2800-square-foot) homes.

-Universe Today

How to get a glimpse of the ISS as it flies over your head?

Now that the ISS is one of the most visible object in the night sky, it would be a shame if you say you never ever seen it. But unlike the Moon or the Venus that appears almost stationary in the sky, the ISS zooms across the sky taking just about 13 minutes to cross the visible portion of the sky on any place on earth. And unless you are standing on a flat desert with nothing in the horizon for miles you wouldn’t even have 13 minutes to view it. if you live in a city with lots of high rise structures and other obstructions your window of visibility is very small and short.

Besides, a satellite sighting is possible only if the following four conditions are met:

  1. The satellite must be above the horizon (this is obvious)
  2. The observer must be in darkness (sun below the observer's horizon)
  3. The satellite must be in sunlight (sun above the satellite's horizon)
  4. The correct side of the satellite must be lit

So in order to see the ISS you have to be out and looking at the precise moment. There are a couple of websites and software (Orbitron) that provide real time tracking of ISS and other satellites. NASA’s SkyWatch is a particularly helpful utility.

On SkyWatch’s online application click on the tab ‘Sat Info’ and select ISS as the satellite from the menu. Now go to the ‘Input’ tab and choose your city from the list. If your city or town does not appear on the list, enter the latitude and longitude of your place which is easily available with a Google search. After entering the data, click on Next Sighting.

nasa-skywatch1

You will be presented with a table that provides you with essential data required to spot the station.

  • The Rise time is the time when the station just emerges into the horizon.
  • The Set time is the time when the station goes below the horizon.
  • The Azimuth is the compass direction where the station would be visible. North is 0 deg, East is 90 deg, South is 180 deg and West is 270 deg.
  • The Elevation is the vertical angle the station makes with the horizon, i.e. the angle at which you have to look up to see the station.

nasa-skywatch-table

You can obtain data for several successive passes and sighting and print it.

Other useful online resources for tracking the ISS are ISS Tracker and ISS: Where is it now?

Assign keyboard shortcuts to open URLs in Firefox

If you remember, we had covered one Firefox addon in the past – Quickmarks, that converts the Function keys into shortcuts to open specific web sites. One drawback of this addon is that Function keys are limited, only 12, and some of them are already assigned with specific functions like F5 for refresh, F11 for full screen etc. So the number of available shortcuts keys is less than 12. Recently I came across another Firefox addon with much better features.

The addon named ShortcutKey2URL allows you to assign keyboard shortcuts to open web sites, and unlike the above mentioned Quickmarks, ShortcutKey2URL allows you to use any of the alphanumerical keys. The keys that are disallowed are the Function keys and the special keys (Enter, Shift, Alt etc)

ShortcutKey2URL-box2

There are three ways to create shortcuts:

- Access ShortcutKey2URL’s configuration window from the Tools menu and directly enter the URLs.

- Open the website in Firefox and click on the ShortcutKey2URL icon that appears on the address bar.

 ShortcutKey2URL-2

- Right-click on a hyperlink and click on Add ShortcutKey2URL in the context menu.

ShortcutKey2URL-contextmenu

To open a URL, simply press the startup key Ctrl + Q (which can be changed) followed by the URL shortcut key. For instance, if you have set the key ‘G’ as a shortcut to open www.gmail.com , press Ctrl + Q, release the keys and then press G. You have to press the shortcut key within 5 seconds of pressing the startup key combination. The validity period of 5 seconds is indicated by a glowing ShortcutKey2URL icon in the address bar.

If you are a keyboard junkie and have no problem remembering the shortcuts, you should have a good time using this addon.

Playboy releases back issues on the web, for free

Here is some good news for Playboy fanboys: Playboy Enterprises Inc, the publisher of America’s (and the world’s) most celebrated men’s magazine Playboy, has partnered with no other than our very own Microsoft and Bondi Digital Publishing, and put up 53 back issues of the magazine on the Web, all for free.

The magazines are accessible at PlayboyArchive[dot]com and no age verification is required, except the familiar “you need to be 18 years old” message. Needless to say, the contents are NSFW (Not Safe For Work or Not Safe For Wife, whichever way you see it) ;-)

playboy-archive

The issues cover the years 1954 through 2007, and appear as they did in the print version, with advertisements left intact. To do so, Bondi Digital Publishing - the software pioneers that developed the platform for The Complete New Yorker - scanned and re-typed each issue of Playboy, the company said in a statement.

"Playboy has an incredibly rich history and an intensely loyal readership," said Hugh M. Hefner, Playboy founder, editor-in-chief and chief creative officer, in a statement. "This is the perfect opportunity to offer them something they have always wanted and also a great way to allow a whole new generation to easily explore the magazine."

Users will need to install Microsoft's Silverlight plugin on their browsers to access the contents. Simply browse through the magazine covers and click on any magazine to reveal large sized thumbnail previews of the magazine pages. Clicking on a page will show high resolution excellent quality scans of the page. The archive is searchable too.

CheckPlaces – Remove invalid bookmarks from Firefox

Remember AM-DeadLink, the tool that scans and removes dead and duplicate links from your browser bookmarks? CheckPlaces does the same. While AM DeadLink is a standalone application that supports Internet Explorer, Firefox and Opera, CheckPlaces is a Firefox addon and works only with Firefox.

CheckPlaces adds itself to the bookmark menu and hence it’s easier to access. You can also reach it from the toolbar or status bar. Checkplaces perform three kinds of cleaning operation – it checks whether the saved links still exist, it checks for duplicate entries and it searches for empty folder. When you run this tool, you will be asked to select the bookmark folders you wish to scan.

checkplaces_options

Choose your bookmark folders and run the scan. The time taken to scan will depend on the number of entries you have, and on completion it will display a detailed results. Finally, click on the Delete button to remove the links with errors.

checkplaces_results

CheckPlaces is an experimental addon, so you will require to login with your Mozilla account in order to install it. If you don’t already have one, then sign up for free.

Gmail adds undo button to send mail

Have you ever sent an email and just after hitting the Send button realized with horror that you sent the mail to the wrong person? At other times you realize an error within the mail or a misspelling.

A new Gmail lab feature now gives you a chance to stop the mail from going out and saves you from sending a follow up mail to apologize for your mistake. Turn on Undo Send in Gmail Labs under Settings, and every time you send an email you will see a new “Undo” link on the sent mail confirmation message. But you have to be quick, because the Undo link works for only 5 seconds.

undo_send2

This feature cannot pull back the mail that’s already gone, but give you enough time to hit the panic button. You must recall that Gmail provides you two more features that prevents you from sending mails that you later regret - the Gmail Goggles that prevents you from sending drunken mails and the Forgotten Attachment Detector that reminds you when you forget to attach the files you said you going to in the mail.

File Destructor – Online dummy file creator

Why would you want to create a dummy file? “To escape the deadline you’ve got to prepare a report or finish your homework by putting the blame on your faulty computer”, explains the creator of File Destructor 2.0. They have got a point.

Back in the good old days, it was possible to get away without doing your homework by claiming that your dog ate it. You can’t use that story any more because now it’s just a matter of taking out another print. And who print reports anyway? We create Word documents, spreadsheets, presentation and pass these in their original digital copies. So if you have been playing on your Xbox and neglecting your work, the only way to save yourself is to put the blame on the computer.

file-destructor

File Destructor is an online service that allows you to create dummy files with a chosen extension (like doc, zip, xls, ppt and a bunch of others) and arbitrary size. The file looks good from the outside but is actually made up of junk. Now you just have to pass this file to your teacher or boss as your completed report. “It doesn’t open? Oops, it must have gone bust ”. A little knot on your brow and a puzzled expression will go a long way.

Actually, there are a lot of ways to create dummy files – one method is right there on your Windows machine. To create any file of any size, just issue the following command at the command prompt.

fsutil file createnew C:\final_project.doc 100000

This will create a file called final_project.doc on the root of your C drive having a file size of 100,000 bytes or about 98 KB.

dummyfile2

There are other tools as well like NOD32 Dummy File Creator Utility, Seedling Dummy File Creator and Dummy File Creator. They all do the same thing.

There is yet another way to create fake corrupted files. Just take any existing file of your required size, make a copy of it and open the file in a Hex editor. Some free Hex editor that you can use are HexEdit, Cygnus Hex Editor and Hexplorer.

hexeditor-dummy

After you open the file, just delete a big chunk of data from the file and save it. There you go, you have successfully corrupted the file. Try to open the file to see whether it has really got corrupted. If not, repeat the steps. Finally rename the file to make it look legitimate. 

Happy goofing!

HighSlide – Javascript image zooming

Want to add a zooming effect to the images on your web site when a visitor click on the thumbnails? Try HighSlide. HighSlide is an open source image, media and gallery viewer written in JavaScript that adds a sleek image zooming animation when a user click on the image.

HighSlide runs entirely on Javascript and can even override popup blockers.

SafeHouse Explorer hides your files in internal and external drives, optical discs and iPods

There are a large number of disk encryption utilities and software to protect and hide files on your computer or thumb drive. Recently, we mentioned one very good tool called My Lockbox and also explained how you can hide complete drives using a registry tweak. Here is another very good encryption utility.

SafeHouse Explorer is a free encryption software that can protect files residing on not only on your internal hard drive but external drives, memory sticks, network servers, CD/DVDs and even iPods. It also supports U3 Smart Drives.

SafeHouse Explorer creates hidden private storage areas on your local hard drive or external media that can be accessed only through the program’s interface and only after you enter the correct password. After you enter your secret password, you access your files using a familiar Explorer-like interface

safehouse-explorer

To start you have to first create SafeHouse volumes by clicking on ‘New Volume’ on the program’s window and specify the location and size of the volume. If the size your volume is going to increase in future you can choose to make the volume resizable. The good thing about this program is that you can create multiple encrypted volumes and these volumes can be moved from their original location to another part of the hard dive without losing any data contained within it. SafeHouse Explorer can also be run as a stand-alone executable file without needing to be installed, meaning that it can be run directly from USB drives, burnt to an optical disc, copied to your iPod and so on. It’s one of the most flexible encryption utility you will ever find.

Iconix eMail ID helps you recognize fraudulent emails

Every once in a while I would receive mails about lotteries I have won or millions of dollars left behind by some heirless millionaire that I could claim. At other times I would get mails from Paypal or banks I have never heard of telling me to verify my credit card. For some people such fraud mails are easy to detect. Still there are thousands that fall prey to it and get robbed off their money, and it happens every year.

The authenticity of a mail from a bank or financial institution or any organization with whom you have financial dealings can be detected from the address the mail was sent from or more importantly, the return email address. Usually these mails are sent from a free email address like Yahoo or Gmail. Sometimes they have a web address that resembles the name of the bank or organization they pose as but slightly altered by omitting, adding or transposing letters. For instance, I remember receiving a mail from Payupal.com. Notice the ‘u’? Well, many people fail to and wind up losing money.

iconix-example

Iconix eMail ID is a free browser plugin that protects you from such phishing scams and help you differentiate legitimate mails from fraudulent ones. Once installed, Iconix eMail ID scans every email you receive and confirms the source of the messages using authentication technologies such as Sender ID and DomainKeys, multiple times. After the authenticity of the sender is confirmed, Iconix adds a small ‘Truemark’ icon in front of the message to let you know that the mail is authentic.

Iconix eMail ID works with Firefox and Internet Explorer and supported service providers include Windows Live, Gmail, Yahoo Mail, AOL Mail and Earth Link. The plugin is also available for Microsoft Outlook and Outlook Express.

Iconix eMail ID currently identifies over 1500 sources which includes banks, various organizations, web services, online agencies, websites etc. It’s understood that Iconix cannot track every email ID in the world or every organization so you are not likely to see the ‘Truemark’ icon before every email, even though they are legitimate. But Iconix covers banks, financial institution and major websites with which people have monetary dealings like Ebay and Amazon quite well, which is all we need.

Note: After you install this plugin, you will asked to send a test mail to email@test.iconix.com in order to ascertain whether the plugin is correctly working on your account. It's not an absolutely necessary step but doing so will help you identify any problem, if it arises.

Project management and collaboration with OfficeZilla

Perhaps one of the best thing that came out of the Internet is the ability to collaborate and work together on a project. While services like Google Docs or tools like CoWord help you to collaborate with other users on a single or group of documents, they are insufficient when your project involves lot more than co-authoring a few Word files.

OfficeZilla is a free project management and collaboration service that provides you a single place from where you can manage and supervise your entire group and the project. OfficeZilla comes with a comprehensive set of tools from chat rooms and forums to To-do lists and calendars. When you first create your group you will asked to select the ones you want to include.

Live streaming video from the International Space Station

NASA will soon start beaming live video from just outside the International Space Station giving people on earth an opportunity to view the planet in a way never seen before. The video will be captured by cameras mounted outside the ISS and the feed will be available between 1AM and 1PM PST, every day of the week!

The show will begin once the the station's crew goes to sleep or goes off duty. The curious timing is because of the fact that NASA has only four communications links for sending data to Earth and it wants to have all of them free for day-to-day operations while the crew is awake and working. There will also be no video from inside the space station to maintain the astronauts’ privacy.

nasa-live

So while the crew on board is asleep, inhabitants on earth will be able to view via the web, the Earth and other parts of the sky as seen from the space station, or parts of the station's exterior as it orbits 225 miles above Earth. The rest of the time, while the crew is awake, viewers will get a graphical world map depicting the station’s current location in orbit above the Earth using real-time telemetry sent to Mission Control. During times when the Space Shuttle is docked to the station, the feed will include those activities. The live feed will also include audio from mission control to the station, whenever available. This is going to be an awesome show.

You can watch the feed at NASA TV by clicking on the Live Space Station Video or by just opening the following URL on your media player.

The show begins on March 22, 1AM PST ( 1:30 PM IST)

NASA to create online multiplayer game Astronaut: Moon, Mars and Beyond

Taking a cue from America’s Army, an online multiplayer game series by the United States Army, the space giant NASA has revealed plans to launch an online space simulator named Astronaut: Moon, Mars and Beyond, in order to get young people interested in a career in space exploration. A playable demo of the game, which is based on the Unreal Engine 3, is expected to be available before the end of the year.

The game will allow players to roam around in a multiplayer experience focused on moon base operations.

“Players will pick a profession like a roboticist, space geologist, astrobiologist or mechanical engineer and work together as a team as they explore space and complete missions, establishing bases and outposts and traveling to the farthest reaches of the solar system,” explained Jerry Heneghan, founder and CEO of Virtual Heroes. “The game will offer both individual challenges and team-based objectives to encourage players to use real-life applications of science, math and engineering to unlock new in-game vehicles, spacesuits, robotics and mining apparatus that will propel them further into space.”

Eventually players may get the chance to provide their own user-created content, ranging from scouting out new paths for space exploration to creating and flying their own ships. But unlike other space-themed MMOs such as EVE Online or Star Trek Online, such ships probably won't be toting laser weaponry.

MMORPGs (Massively Multiplayer Online Role Playing Game) are becoming increasingly popular. Some popular examples are World of Warcraft, which dominates with a massive 11.5 million monthly subscribers, Second Life and space simulation roll playing games such as EVE Online and Star Trek Online. However, it remains to be seen how the game appeals to space game enthusiast who are used to fantasy space environment and blasting aliens with exotic guns, since NASA’s game is going to focus more on education and exploration rather than the trigger.

The game’s screenshots looks a bit dated for a game that is slated to release by 2010, it’s crappy to be honest. Hopefully, NASA and it’s game developers will work out on the graphics and the game play before the game is out, and ensure that the fun is not missing.

Google India launches Google Noticeboard

Last week, Google India quietly launched another voiced based product after the much fanfare release of Google Voice worldwide. This new service called Google Noticeboard is intended to improve communication within rural Indian communities where not everybody owns a computer.

Google Noticeboard is like a voicemail application that can be used on shared computers, for instance the only computer on an Indian village. The administrator sets up a “noticeboard” on this shared computer or on an Internet cafe and this applications then acts as public noticeboard, where anyone can record a voice message. Text can also be added, but the emphasis is on voice communication since the target users of this application is expected to have low literacy rates. Using Google Noticeboard, people from the village can check for new group messages on any shared village computer.

google-noticeboard

Communities with access to shared computers can use the Noticeboard for exchanging messages related to community announcements, social interactions, local buying and selling, and information that is of wider interest to the community. The Noticeboard may also be used for the community to engage in a dialog with benefactors, public servants, and other service providers who are geographically distant. For example, residents of an apartment complex can use the Noticeboard for posting announcements, or NGOs who own and operate computer centers in several villages can use the Noticeboard to enable village residents to communicate amongst themselves.

To use this Noticeboard, all it requires is a Firefox addon that is to be installed and configured on the shared computer or computers. As a part of the configuration, each community Noticeboard is also associated with an email address and a list of contacts.
