Sky tracking International Space Station (ISS Zarya) over Thiruvananthapuram Kerala, INDIA

For the first time, I saw International Space Station (ISS ZARYA) over Thriuvananthapuram (Trivandrum), Kerala, South India, INDIA

Captured using 18mm lens with 30s exposure. It was moving so fast, as I got a moment to capture it. Next time I will do some homework and will try to get the full arc of its passage. Next is on Wednesday 1st Jan 2014. Waiting for it.

Much more enhanced image of ISS, but I have found an un identified object on the top center while doing the post processing.

Here is the processed image. It should be another satellite or a flight.

Firefox broswer filled with black moving pixels [SOLUTION]

Problem : Just an hour ago I was browsing a web page and noticed that a few stray pixels were showing up, then going away or moving sort of in a confetti effect. When I scroll it gets worse and the pixels pile up and sometimes slow down the entire browser. I cleared my cache and updated Firefox and all my add-ons, restarted the browser, and even made sure it wasn't my monitor by watching my desktop, opening other programs, and even checking in other browsers. Only Firefox is causing this problem. It's really annoying. Is there any way to fix this? 

 Solution : 
1) Update your video card with the latest drivers.


2) Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
  • Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
  • In the Firefox options window click the Advanced tab, then select "General".
  • In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
  • Now, restart Firefox and see if the problems persist

Attacks against WordPress and Joomla sites have tripled

Hosting providers around the world are seeing a massive increase in brute force attacks against WordPress and Joomla sites. Attackers are looking to gain access to and compromise accounts, but failing that, they are slowing down their targets or even rendering them unavailable as they exhaust the sites’ resources.
Melbourne Server Hosting is reporting that it has seen signs over the past 48 hours of increased attempts, while Immotion Hosting has noted they are coming from a large amount of IP addresses spread across the world. This would suggest the attackers are using a botnet to break in; HostGator has said at least 90,000 computers are involved while CloudFlare has noted it “more than tens of thousands of unique IP addresses” are being used.
Sucuri, a security firm that blocks various types of Internet attacks, reports that it has also seen a notable increase. The company shared the following data points:
  • December 2012: 678,519 login attempts blocked.
  • January 2013: 1,252,308 login attempts blocked.
  • February 2013: 1,034,323 login attempts blocked.
  • March 2013: 950,389 login attempts blocked.
  • April 2013: 774,104 login attempts blocked for the first 10 days.
The top five user names being attempted are admin, test, administrator, Admin, and root. The top five passwords being attempted are admin, 123456, 666666, 111111, and 12345678. Obviously, if you are using any common user name or password, you should change it immediately.
In other words, Sucuri has been seeing 30 to 40 thousand attacks per day for the last few months, but this month that number has increased to 77,000 per day on average. In the last few days, the firm says the figure has reached more than 100,000 per day, meaning the number of brute force attempts has more than tripled.
For those who don’t know, a botnet refers to a group of computers (sometimes called zombies) that have been infected with malware to perform tasks for whomever distributed said threat. This individual, or organization, controls the botnet by sending instructions to the zombies from one or more Command & Control (C&C) servers.
A brute-force attack, meanwhile, refers to the systematic checking of all possible passwords (or just popular ones) until the correct password is found. A botnet is not required, but can help in the process as multiple computers can be used to check different combinations and avoid triggering multiple attempt limits.
While these attacks against popular content management systems are nothing new, the sudden increase is a bit worrying. Until the botnet in question is taken down, however, there is not much that can be done aside from ensuring you are taking every precaution. That includes using a solid username and password combination as well as ensuring your CMS and plugins are up-to-date.
Update: WordPress creator Matt Mullenweg has released a statement regarding the issue:
Almost 3 years ago we released a version of WordPress (3.0) that allowed you to pick a custom username on installation, which largely ended people using “admin” as their default username. Right now there’s a botnet going around all of the WordPresses it can find trying to login with the “admin” username and a bunch of common passwords, and it has turned into a news story (especially from companies that sell “solutions” to the problem).
Here’s what I would recommend: If you still use “admin” as a username on your blog, change it, use a strong password, if you’re on WP.com turn on two-factor authentication, and of course make sure you’re up-to-date on the latest version of WordPress. Do this and you’ll be ahead of 99% of sites out there and probably never have a problem. Most other advice isn’t great — supposedly this botnet has over 90,000 IP addresses, so an IP limiting or login throttling plugin isn’t going to be great (they could try from a different IP a second for 24 hours).

A tiny (625 bytes gzipped) tool for easily loading html fragments and templates.


Fragment.js allows you to load html fragments into any element, by just adding a data-fragment attribute.
This was loaded with fragment.js

Templating example

You can also use it for loading templates with the data-fragment-json attribute. Mustache, Handlebars and Underscore are supported by default and will automatically be used if they're available in the global scope. But you can just override the window.fragment.render function if you want to use something else.
data-fragment-json="fragment.json">This is {{adjective}}!
This is awesome!


If the element already has an innerHTML, you only use the data-fragment attribute, and don't provide a custom renderer; fragment.js will attempt to render Mustache, Handlebars then Underscore with the innerHTML as input.
fragment.js is really fantastic!


Of course, combining the two attributes also works.
data-fragment="mustache-fragment.html" data-fragment-json="fragment.json">
fragment.js is really awesome!

JSONP example

If the window hostname isn't the same as the json url hostname, it'll try to use jsonp. By default it uses callback as the callback parameter, but you can change it by changing fragment.jsonp
data-fragment-json="http://search.twitter.com/search.json?q=javascript&rpp=2"> {{#results}} {{from_user}} said: {{text}}

Buddypress wrong url issue and migration to new server [Solved]

Migrating a WordPress site can be something of a scary challenge, but we do it a lot, and we’ve become used to it. There are many good reasons to move a site – for example, you might set one up in a subfolder, and decide to move WP to the root. Or perhaps you’ve built a site on localhost and now need to put it on a live server.

If you do it incorrectly, you stand to lose all your widget settings, some file links and so on. This wasn’t a problem with ‘classic WP’ years ago, but these days there are many many paths stored away in the database, in various forms, and catching them all can be somewhat tricky.
Here I show you the steps we take moving a localhost site to a live domain. We’re using WPMU which is running the BuddyPress plugin suite.

The Local Install

Here’s our site on our localhost. As you can see, it’s pretty basic, but everything’s there that needs to be there – we know all elements of the install works, and now we want to pop it onto a live server. In this lesson, we’re going to use FileZilla and ftp the files across from our local install.

Copying the Files

On the left you can see we’ve navigated to our local filesystem for this install. On the right, we’re connected to the server. There are already files there, because we have an old install running. You should delete all the files and replace them with the new ones in this case, but if you are replacing a site do make sure you have a copy of everything. Merging sites is much harder than migrating – and way beyond the scope of this tutorial.
So – select and drag all the files from one side, to the other.

Moving the Database

Our preferred tool for administering databases is mySQL Administrator. A free tool that really simplifies a lot of DB Admin tasks. Use this to take a backup of your database. You’ll need to create a new backup project.
  1. Click Backup
  2. Create New Project
  3. Select the Schema you’ve been using
  4. Click to move it across, selecting ALL tables (unless you have multiple installs in one database, in which case, just the tables for the install you’re interested in)
  5. Give it a name
  6. Save Project
  7. Execute the Backup

Backup Done

You should now have a backup.
Because the server we’re using doesn’t allow connections on Port 3306, we’re going to use phpMyAdmin there. This is no problem at all, but if you were using mySQL administrator you could use the restore tools there. If you’re doing this kind of project you should really know how to use these tools anyway – I’m only explaining these steps for completeness sake and showing you a migration I’m doing myself that’s likely to be typical.

Editing the SQL

A database backup is done simply as a big set of SQL statements that you can run. If you’re migrating to a different database you’ll need to edit the CREATE and USE statement to tell it which database to use.
Be very careful with this database dump by the way – database dumps are a very easy way for hackers to get into your system and find out lots of information you’d rather not give away.

Importing The Database

Now you need to Import the Database. We’re using phpMyAdmin for this. If you have any tables there already, it’s probably best to drop them. All of them. Like I say, if you’re merging you’re going to need more help than this guide can provide.
  1. Click on the Import tab
  2. Select your file (if it’s bigger than your sever’s upload limit then you’ll have to speak to your admin guys about how to do this.
  3. Press the Go button!
Once the import has run successfully you should see a message saying something like "Import has been successfully finished, 95 queries executed." – and it can be an awful lot more than 95 queries! It can also take quite some time. If you need to handle large datasets it’s far easier to use the mySQL Administrator tools – phpMyAdmin can get clunky.

Visit the Site

If you try to visit the new uploaded site at the moment you’ll get a Fatal Error because all sorts of things are confused.
You need to change the wp-config.php file.

Changing wp-config.php DB Settings

Change 1, 2, and 3 to match your server’s database settings.
Change 4 to the appropriate path. Most installs are in the root directory, so that would mean $base = ‘/’;
Change 5 to the domain name in use.
Change 6 from ‘/buddypress.11/’ (or whatever your local path is) to the new path, like in 4, so in most cases that will be ‘/’ also.

Search & Replace on the Database

You now need to run a search and replace on the database – including all incidences of code within serialised PHP strings. There is an excellent and free utility written by Interconnect IT, called the Safe Search and Replace Tool.
I can’t emphasise enough that it’s important to handle serialised PHP correctly. If you don’t, then settings will go missing, fields will get corrupted, and your site runs a severe chance of not working on the new location. It’s a pain, but it’s important.
So, download the program, place it in your blog’s root folder and then run it by visiting the appropriate URL.
If you’re getting confused at this point, perhaps you shouldn’t run the program. Just saying, because it can cause plenty of damage!

Running the Script

Simply visit http://www.example.com/searchreplacedb.php in your browser to fire off the script. This will run. If you experience a time-out, or too much output, you may need to go into the script and remove any echos that are slowing it down. I’ll probably comment this out in due course anyway, but for diagnostics purposes I’ve left it. Once run, you should see something like the above at the bottom. Even a very large search and replace should only take a few seconds.

Some Tweaks

Check that you can navigate your site in its new location.
You may have to modify .htaccess to fix paths, and you may need to check your uploads folder for media. But that’s it. All should be good.

Extra Steps for WordPress MU

If you’re using WordPress Single User, then that’s it. You’re all done!

But in this example, we’re running BuddyPress on WordPress MU, and that means one extra step. In phpMyAdmin you need to open up (1) wp_blogs, (2) click the browse tab, and (3) click the edit tab for each row. If you have a lot, you may wish to run another searchreplacedb.php against the database, looking for localhost.localdomain and buddypress.11 and swapping them appropriately.

Indian Army : Ghost Solder on Duty Reporting Sir..

“Harbhajan Baba ki Jai” (Glory to Harbhajan Baba), cry out many voices in unison as tourist buses, packed with both Indian and foreign tourists, cabs full of people and private vehicles, all cross the bridge over the Teesta River to enter the border sate of Sikkim in India. Harbhajan Baba is revered across Sikkim as a sacred person. 

This is his story:
nathula pass.jpg
Nathula Pass

The late Harbhajan Singh enrolled in the Punjab Regiment in 1966, joining the army at an early age. He became a Sepoy (a rank in the Indian Army) and found himself posted on the misty heights of the China - Indian border, near Nathula Pass. 

Two years later, while escorting a mule caravan from his battalion headquarters at Tukla to Deng Chukla, he fell into a fast- flowing stream and was washed away.

The army searched for his body, but it wasn’t found until he began appearing in the dreams of other Sepoys in his unit. In the dream, he informed his colleagues that he was no longer alive and told them where to find his body. He also told them that he would continue to be a soldier always and not tolerate in lax patrolling of this sensitive border. 

When a search party was dispatched to the spot that had been described in the dreams, Sepoy Harbhajan Singh’s body was found. He was cremated with full military honors, and a memorial shrine was made at Chhokya Cho dedicated to his memory. This shrine is a three-room complex where there is a bed laid out for him and his uniform and boots displayed for the visitors. The caretakers swear that each morning the bed sheets are crushed as if someone has slept in the bed the previous night and the carefully polished boots are soiled and covered with mud.

There are also many army reports of a lone man patrolling the area. Soldiers deployed in the area often talk of a lone uniformed man on horseback patrolling the region. Forces on the other side of the border have also confirmed these reports and claim that they too have seen the ghost rider.

Over the years, soldiers here have claimed seeing Harbhajan Singh in their dreams where he instructed them of unprotected areas from where the Chinese could attack. His instructions generally proved accurate and the legend of Baba Harbhajan Singh grew.
There are also stories of battle-weary soldiers who have nodded off during their patrols being woken up with stinging slaps. Obviously, this ghost does not tolerate laxity in duty.

Baba Harbhajan Singh
Baba Harbhajan Singh

The Indian army continued to promote this Sepoy as if he were still alive. A paycheck would be sent home to Punjab every month and he was given annual leave on September 14 every year, when soldiers would pack his trunk with basic essentials. Two soldiers would accompany the trunk of ‘Capt Harbhajan’ all the way to Punjab by train, and it would be brought back after a month the same way. This tradition continued for years until he was retired a few years back.

When I visited the shrine of Harbhajan Baba on my way to see the Nathula border, I witnessed this incredible scene of a dead man’s belongings being packed in a trunk, and being seen off by his fellow officers for a month’s leave.

At 14000ft, located amidst towering mountains, broken by gushing waterfalls and colorful heather and gorse bushes, this shrine attracts devout believers from all over India. Following the twisting narrow roads at a steep incline, vehicles snake their way to this shrine and all people passing through this area, civilians and soldiers alike, generally stop at the shrine to pay obeisance to the revered Baba. Not doing so is supposed to bring bad luck.

Baba Harbhajan Singh Shrine

Way to Nathula

Perhaps the Chinese are just as superstitious as we are because at the monthly flag meetings between the two nations at Nathula, even today the Chinese set a chair aside for the ghost of Harbhajan Baba.

As the Indian flag flutters in the icy winds, it grows misty. Cold fingers of fog creep up to wipe out the sun and it is not difficult to imagine a lonely figure guarding his country’s borders with a zeal that has lasted beyond death.

Believe me, this shrine with its resident ghost sent shivers down my spine when I heard the story of this patriotic ghost soldier while sipping hot tea the caretakers offer to all who come to visit this shrine in the remote border area.

Top 10 best Science books that you must read

A Briefer History of Time
Stephen Hawking and Leonard Mlodinow
9780553385465 1285576146
Stephen Hawking is one of the world’s most famous physicists. He is well-known by the general public for his extensive work in theoretical physics, cosmology and unfortunately his debilitating battle with motor neuron disease. A Briefer History of Time is an updated and easier to read version of his 1988 bestseller, A Brief History of Time. The book – like its predecessor – reads like a biography of the universe, and is a great introduction to the world of physics. The Sunday Times sum it up best: “This book marries a child’s wonder to a genius’s intellect. We journey into Hawking’s universe while marveling at his mind.”

An A-Z Guide to the Elements
John Emsley
Full Title: Nature’s Building Blocks: An A-Z Guide to the Elements. A chemist and doctor of science turned full-time writer, Emsley is responsible for many popular science books. Nature’s Building Blocks looks at all the elements from Actinium to Zirconium discussing their role in nature, where the element originated, the common uses of the element, how the elements are used in health or illness and loads of other interesting and quirky facts around them. The book serves as a detailed and interesting essay on each element, much like and expanded and entertaining version of the periodic table.

Death by Black Hole
Neil Degrasse Tyson
Full Title: Death by Black Hole: And Other Cosmic Quandaries. Tyson is a very charismatic, enthusiastic and entertaining fellow and that is very prominent in his works and media appearances. His book Death by Black Hole is no exception. In it he explores everything from the destructive nature of black holes to the gaffes made in science fiction films. His humorous nature and enthusiasm make this book a very enjoyable read. After reading this it’s easy to see how he got voted one of the most influential people in the world and perhaps even the sexiest astrophysicist alive, a few awards among many that he has accumulated over the years.

The Greatest Show on Earth
Richard Dawkins
Full Title: The Greatest Show on Earth: The Evidence for Evolution. Evolutionary biologist and prominent atheist Richard Dawkins goes to great lengths providing evidence for evolution in The Greatest Show on Earth. From artificial to natural selection, fossil records, the human genome project and there’s even some plate tectonics for good measure. If you’re familiar with any of Dawkins other works then you already know what to expect from this. If not, then be prepared for a passionate, thorough, witty and depending on your views, perhaps even controversial look at the origin of our species. Also be sure to read the subplots that are in the footnotes for interesting side notes on the main content of the book.

Michio Kaku
Full Title: Hyperspace: A Scientific Odyssey Through Parallel Universes, Time Warps and the 10th Dimension. Michio Kaku is a theoretical physicist, one of the founders of string theory and a well-known popularizer of science through books, radio, television and film. Much of Kaku’s work focuses on the hypothetical future of Earth and of science, making predictions about humanities future and the future of the universe. His bestseller, Hyperspace was voted one of the best science books of 1994 and it’s easy to see why. In Hyperspace, Kaku looks at string theories proposal of 10 dimensional space time and makes the complex subject approachable by using it to ponder the possibility of time travel and multiple universes. It is a must read for anyone interested in theoretical physics without being lost in the complexity of the equations involved.

Manjit Kumar
Quantum Lr
Full Title: Quantum: Einstein, Bohr and the Great Debate About the Nature of Reality. Another physicist and philosopher (there seems to be a trend here), Kumar had written scientific papers for journals, newspapers and co-written popular science books before venturing into his own book, Quantum. Quantum is a biography of quantum physics, centered on the debate between those who did and didn’t agree with quantum theory. The draw of this book is how the great minds of physics went head to head in a battle of the brains around what theory they believed was right. The book gives a history of how physics got to where it is and looks at other notable physicist such as Plank, Schrödinger, Bohm and Rutherford and the concepts and developments they brought to it.

Matt Ridley
Full Title: Genome: The Autobiography of a Species in 23 Chapters. Matt Ridley is a science journalist and author. He is best known for his books on genetics, evolution and looking at human behavior from an evolutionary viewpoint. Genome has one chapter for every pair of human chromosomes, thus using the book itself as a metaphor for the human body. Each chapter looks at a different pair of chromosomes and Ridley picks a gene from each to discuss throughout the chapter. From looking at these genes he covers the rise of homo-sapiens, an individual’s likelihood of inheriting a disease, and even their ability for language. Genome is a great book to gain knowledge on genetics in an accessible and entertaining way.

A Universe from Nothing
Lawrence M. Krauss
Full Title: A Universe from Nothing: Why There is Something Rather Than Nothing. Lawrence Krauss is a theoretical physicist known for his work on dark matter and for publishing several popular science books. A Universe from Nothing is a New York Time best-seller and the book stays true to the title looking at why and how the universe began from “nothing.” The book aims to be physics’ answer to philosophy’s questions and maybe after reading it you might, like Stephen Hawking, conclude that philosophy is dead at the hand of physics. Either way A Universe from Nothing is a very insightful cosmology book and well worth a read to come to your own conclusion on philosophy’s fate.

Carl Sagan
Carl Sagan Cosmos 13 Episode Tv Series
Carl Sagan was a world-renowned astrophysicist well-known due to his work with NASA on extra-terrestrial life. Sagan played a significant role in choosing the contents of the voyager golden record which is currently on-board the voyager spacecraft, soon to be the first man-made object to enter inter-stellar space. Sagan was also well-known for the television series ‘Cosmos: A personal voyage’ the series that this book accompanies and one I can’t recommend highly enough. Though Cosmos was published over 30 years ago it is still a relevant and intriguing read filled with amazing imagery of the universe. In it Sagan looks at the evolution of our universe, the evolution of science, and how people are quite literally the universe conceptualizing itself. 

Wonders of the Universe
Brian Cox
Brian Cox is a particle physicist, a familiar presenter of many BBC documentaries on cosmology and he was even a keyboard player for a pop band! His book Wonders of the Universe compliments his television series of the same name. Using materials found on earth and glorious illustrations throughout Cox makes it easier for his audience to understand the concepts in his book. The book explores the marvels of deep space looking at distant stars, black holes, the death of our sun and so much more. Just like Sagan’s Cosmos this book is also based on a fantastic television series, is beautifully illustrated, and would make a great coffee table book.
