Upcoming Movies

Some of the big movie releases like The Avengers, The Dark Knight Rises, MIB3, The Amazing Spiderman, and The Bourne Legacy made their way to cinemas in Sri Lanka over the past few months. However, one of the most anticipated movies of 2012, "Prometheus" which was also reviewed as one of the few "good" 3D movies of the year did not make it to any movie theater in Sri Lanka.

Here are three upcoming movies that look interesting. We'll have to wait and see whether these three movies will be screened at cinemas in Sri Lanka.

Looper

Looper is a science fiction film starring Bruce Willis, Joseph Gordon Levitt(Robin Blake in TDKR) and Emily Blunt. It has a plot related to time travel and Bruce Willis and Joseph Gordon Levitt both play the same character at different ages of his life. Aside from the possible paradoxes arising due to the time travel plot, the film seems to be an entertaining action flick.


Cloud Atlas

This is termed an ""experimental" movie because it differs in style to most movies produced today. It is based on a book of the same name and revolves around six different narratives. It is a drama film with sci-fi elements. While the reception at the Toronto film festival has been positive, its uniqueness might also be off-putting to some.


Dredd 3D

image from Wikipedia

This movie can be seen under the upcoming movies section in the EAP movies website. It will most probably come to Savoy 3D after Step Up Revolution. It is an adaptation of a comic strip "Judge Dredd" and is set in the future. While it looks like a low budget cheesy sci-fi movie, so far it has got positive reviews from the rotten tomatoes website. The story revolves around a violent cop who is given the power of judge, jury and executioner to maintain law and order.

The Games Behind Portal

The first person puzzle game, Portal became instantly popular due to its unique gameplay and humorous script. It was a fresh new addition to the video game industry and it left gamers yearning for more after completing the brilliant but short game. The release of Portal 2 was well recieved by gamers and critics alike because it brought back the unique gameplay of portal with additional elements in a full-length gaming package. The custom map editor of portal 2 brought about more opportunities for fans to immerse themselves in the puzzle riddled portal universe.

After completing both Portal games and additional maps, if you are still looking forward to a gaming experience similar to it, then the best place to look for it is, the birthplace of the concepts of these games - DigiPen Institute of Technology. DigiPen Institute is a leading game developing institute that has produced prolific game developers over the past few years.

The game that Portal is based upon is, Narbacular Drop. The idea of solving puzzles by manipulating objects through a system of portals was introduced in Narbcular Drop. Unlike in Portal though, it has a fantasy background and it's possible to create portals through an existing portal. The entire development team of Narbacular Drop was hired by Valve corporation to work on Portal. Being the predecessor to Portal, this game is definitely worth checking out. This game can be downloaded through the link at he end of this post.




The concept of propulsion and repulsion gels in portal 2 is also taken from a game called "Tag - the power of paint" which was also developed by students at DigiPen institute and just like before, hired by Valve to work on Portal 2. In Tag, the player is equipped with a paint gun that can spray different colours of paint onto surfaces that will give the player special abilities which are to be used to solve puzzles.

A Brief History of Management

Management is an essential component in any business or organization and it applies at every level in all types of organizations. Management can be defined as "The attainment of organizational goals in an effective and efficient manner through planning, organizing, leading and controlling organizational resources." The terms planning, organizing, leading and controlling are called "management functions". Today management is a broad area of study that has been developed throughout the past century and is still evolving.

The invention of the steam engine by James Watt kick-started the industrial revolution. With the industrial revolution, the concept of a factory emerged. Factories that did mass production with thousands of workers from different backgrounds mushroomed in the industrial world and thus a need for management arose. The idea of management at that time was to bring efficiency and order to an otherwise chaotic workplace.

This was the time when management was perceived and studied as a science. Frederick Winslow Taylor is considered the father of Scientific management. Through his experience and observations, Frederick Taylor came up with scientific management which aimed at increasing efficiency at the production level. In his monograph "The principles of Scientific Management", he highlighted four principles. They are
1. Study the way a job is performed and create a new scientific way to perform it with maximum productivity
2. Codify the new method into rules and train and equip the workers with the new method
3. Select workers whose skills match the rules developed and provide detailed instruction and supervision.
4. Establish fair levels of performance and reward higher performance.
In Scientific Management it it assumed that man is an "economic animal" and that money is the motivating factor. Also this system of management only applies at the operational level of the organization.

While efforts in management were only applied to the operational level of an organization, gradually attention moved to the upper hierarchical levels of the organization. This led to the development of the "Modern Management theory". A french mining engineer Henry Fayol is considered the father of modern management theory. Fayol was the first to define the 4 management functions quoted in the first paragraph of this post. In his book, "Industrial and general Administration", he divided all administrative activities into six categories. They are,
1. Technical
2. Commercial
3. Financial
4. Security
5. Accounting
6. Administrative
He also proposed 14 principles of administration - Division of work, Authority and responsibility, discipline, unity of command, unity of management, subordination of individual interests to the common good. remuneration, centralization, hierarchy, order, equity, stability of the staff, initiative, espirit de corps.
Unlike Taylor's Scientific management which focused in the operational level of an organization, Fayol's theory of management focused in the managerial level. Fayol also claimed that workers can be motivated by more than just money and also argued for equal treatment of all workers.

While the management process that is practiced today is mostly based on Fayol's theories, certain aspects of management are still evolving. The functions of management are interconnected and each function needs to be performed collectively and to various degrees for the management process to be successful. Although based on scientific principles management also requires a certain level of creativity in application. The management process can also depend on factors such as the culture and structure of the organization. By adapting to this dynamic nature and selecting the proper approach to management, organizations will be able to succeed in today's world.

Breaking Google Doodle Olympic Records

The recent series of Olympic Google doodles are really fun. It's a great way to waste a couple of minutes and compete with your friends or co-workers. But it can be very frustrating when you always end up getting a lower score than your buddies ;).. So here is a way to become a champion in the doodle olympics. Keep in mind however that this is a way of cheating the doodle, so if you are not keen on cheating then stop reading  now. :D

Assuming that you are ready and willing to cheat in the doodle olympics, here's how you do it. (Instructions given here are for the Google Chrome browser) For this demonstration I have used the most recent slalom canoe doodle, but the basics are the same for any event. First, take you own cool time and finish the game and obtain your result.


Then right click anywhere on the doodle and select "Inspect element"


In the window that opens, locate the four lines that I have bracketed in green. You can use the search feature on the top right corner of the page element window to locate it quickly. (Click on the image to enlarge)


These are the lines that are required to be changed to change your result. The first line contains you timing. double click on it and change it to your desired timing. The next three lines are for the three gold medals that accompany the timing. The last three letters in these three lines will be "smg" or "smh". Change all three to "smg" to get all three gold medals.


Make the changes and close the page element window to view your doctored result. Now go and brag to your friends! :D

3D at Savoy, MC Superior or MC Platinum?

A couple of months ago MC Superior was the only 3D cinema in Sri Lanka. Now there are three 3D cinemas. After the conversion of the old theaters Savoy Wellawatte and Majestic Platinum to 3D, movie fans can now choose which movie they want to see in 3D. These three 3D cinemas in Colombo use three different 3D projection technologies. Each has its advantages and disadvantages and so, here is rundown of all three 3D systems in the three cinemas.

MC Superior 3D uses the Dolby 3D system which is an interference filter method. The glasses used in it are passive and contain wavelength filtering lenses. It is a relatively new technology and produces high contrast vivid colour images while minimizing ghosting.

MC Platinum 3D uses an active shutter technology which is also used used in most 3D televisions. Active glasses that are powered by batteries are used. Due to the shutter effect, in the long run due to problems in batteries and IR emitters, flickering can be a problem. However at the moment no such problems are present at MC Platinum, and hopefully it remains that way.

The latest addition, Savoy 3D uses the RealD XLS system with the latest Sony 4K projector. Lightweight, circularly polarized glasses are used. to compensate for the light loss during polarization a Silver screen is used here. The Sony 4K projector has a very high resolution and simultaneous projection of both left and right eye images give rise to a smooth 3D effect.

UPDATE (19/2/2014)

MC Platinum 3D No longer uses the problematic active shutter technology. They have switched to a polarization method with lightweight, passive glasses like in Savoy.

Active shutter 3D technology

The recently converted MC Platinum 3D uses the active shutter technology. It is the same technology that is used in most 3D televisions. The basic concept here is to provide the left eye and right eye images to the left and right eye sequentially by blocking the view of one eye at a time. This is achieved by the use of liquid crystal shutter glasses. the view through one lens is blocked using the liquid crystal layer between the lens while the other lens remains transparent and shows the corresponding image. this alternating shutter effect happens very rapidly and is synchronized with the images projected (or displayed) on the screen. This method is also called the Eclipse method.

MC Platinum 3D uses shutter glasses of the brand Hi Shock. Active shutter glasses need to be powered by batteries and they wirelessly communicate with the projector or the television in order to synchronize the shutters. In order to avoid flicker the refresh rate needs to be very high. The refresh rates are usually double that of normal projection or other 3D projection systems. The brightness also needs to be higher than normal just like in polarized 3D systems.

UPDATE (19/2/2014)

MC platinum 3D No longer uses the Active Shutter system. Recently they switched to a polarized filter system similar to that of Savoy 3D. The lightweight, passive glasses used in this method means that flickering and other problems associated with active shutter systems will no longer ruin your movie experience.

Was Banning DDT a Mistake?

Banning of the pesticide DDT is often credited as one of the best decisions made for the betterment of human beings and the environment. However this decision has also led to more than 30 million deaths since it was implemented. It was a decision made without any scientific basis and has resulted in irreparable losses in developing countries.

DDT was banned in 1972 by the EPA claiming that DDT is a carcinogen and has harmful effects if exposed to the environment. Public support for this cause came by means of a then best selling book by Rachel Carson, known as "Silent Spring". However it has been found out that Silent Spring was not based on sound scientific findings and also that the decision made by the EPA to ban DDT was based on fraudulent reports and was a result of bureaucracy.

DDT was a very effective pesticide that was used to control malaria. Countless scientific experiments have reported that DDT has no harmful effects on humans or nature. But apparently these scientific findings have not been considered when deciding to ban the said pesticide that ultimately led to millions of deaths. The negative effects of banning DDT is most felt in developing countries. For instance, in Sri Lanka alone, spraying of DDT has reduced the number of malaria cases from 2.8 million in 1948 to 17 in 1963. After the ban was imposed, the number has risen again to 2.5 million.
(source : http://dwb.unl.edu/Teacher/NSF/C06/C06Links/www.altgreen.com.au/Chemicals/ddt.html)

The actual reasoning behind the decision to ban such a useful pesticide is not known. Developed countries don't feel the impact of it as much as the developing countries do. In spite of this, forcing developing countries also to ban DDT is clearly not justified. Just like most cases in the modern world, it seems the agency behind this decision had its own agenda and gains to make from such a decision.
