Creating a multithreaded application requires 4 major steps and of the four, the design and implementation part is not often discussed. The following rules will give you a better chance of writing the best and most useful threaded application:
• Identify accurate independent computations – simultaneous execution is not possible unless the executable similar operations can run independently of one another.
• Concurrent implementation should be at the highest level – during the analysis phase of the threading methodology, identify the hotspots – code segments that require the longest execution time – and if they can run parallel you will be able to get its maximum performance.

All About UBUNTU

Ubuntu is an open source operating system designed for desktops, laptops and even servers. It is distributed by Linux based on Debian GNU/Linux. Ubuntu is owned by Mark Shuttleworth, an entrepreneur from South Africa where the name Ubuntu originated. In case you are curious about the concept of Ubuntu, it is rendered as We are people because we are people. Ubuntu wants to make this OS available for everyone thats why they made it a free software. It aims to give its users an up-to-date yet stable OS. Ubuntu supporters testifies that even the average users will enjoy Ubuntu due to its usability, easy installation and the user-friendly interface.

enterprisedb-banner-cloudIt is clear that free open source software can cut any business’ cost significantly. However, many companies and businesses still stick to expensive commercial database software instead of switching to open source software due to the question of reliability and performance, because if it fails in that, then the fall out could possible entail bigger losses.

Still, the tide is changing with EnterpriseDB CEO Ed Boyajian quoted as saying that the “situation is changing very, very fast” and that “open source use is getting stronger”. However, he does acknowledge that “in the database space it can be very costly to move from one platform to the other” which is why they have made a version that is compatible with Oracle technology. This means that applications can then run on both on Oracle and Postgres, so that no rewriting of code has to take place.

With transitions costs cut by this, and the significantly cheaper price of EnterpriseDB, there is now a reliable open source database software available for enterprise needs. Still, it’s up to the business execs to decide whether the financial rewards is worth the investment that switching will still require.

Advantages of Open Source

May 21st, 2013

Open source is advantageous to its users mainly because it involves minimal cost thus allowing free use and even modifications. It as well involves convenience in distribution making it possible for the majority of the online community to enjoy its involved benefits that can contribute to the ease in one’s daily consumption of the Internet. Another is that open source is known for involving a secured usage. It is often said that the wide reach of such source leads to risks, viruses, and lack of security but actually, the opposite happens with open source. This kind of source goes with secured usage mainly because there are numerous users that enable easy access and fixing of arising issues allowing anyone to easily fix bugs or remove viruses. With all those being said, definitely open source will continuously be appreciated and supported by the majority and nonetheless, its benefits and usage will always be considered vital and essential.

Free Open Source Software

May 21st, 2013

Free Open Source Software, also referred to as the FOSS, is a product of the most commonly used software namely free software and open source software. There are several confusions brought by the rise of FOSS and it helps to first understand how the two involved software individually works. Taking one at a time, free software, in simple terms, is software that is free of cost. Online users are given that freedom to easily access, edit, download, and use such kind of software. Usually, its access is attained through readily available source codes that make its usage possible. On the other hand, open source software can be considered more specific in a sense that source codes are made available but involving a license. This license is primarily owned by the host thus giving them the right to decide on whether allow other users to access and use the involved software. These two types collaborated then led to the existence of the Free Open Source Software.

Open source and closed source seem to be continuously compared. What exactly are the differences of these two types of source? There are four bases of comparison namely software development, profit, security, and reach. Definitely, software development with closed source is considered to be of great quality knowing that competitors are inevitable. On the other hand, open source involves shared software thus reducing the involved quality. Open source paves way for greater profit mainly because of the fact that more incumbents are present more specifically, its usage is more open to the online community resulting to more earnings and profit for the host. Security of open source is as well considered to be of greater consideration. Comparing to closed source, open source is believed to be “safer” because it allows more users to use, edit, and fix any arising problem. Lastly, the reach of open source, without a doubt, is wider thus not limiting the maximization of its involved benefits.

Choosing Your Ubuntu Version

April 28th, 2013

ubuntu logoCanonical released the latest version of Ubuntu, Ubuntu 13.04, last week giving Ubuntu users a choice between that and Ubuntu 12.04.2 LTS.

So what’s the difference between the two, and which one should your download for your desktop?

Ubuntu sums it all up with these words, “Ubuntu 13.04 gives you all the latest features, while Ubuntu 12.04 LTS comes with extended support.” The Ubuntu 12.04.2 LTS release (LTS stands for long-term support) comes with “guaranteed security and support updates until April 2017″ while the Ubuntu 13.04 will only be supported for 9 months. This means that if long term support is important to you, then it’s quite clear which version you should go with.

On the other hand, Ubuntu 13.04 has better features for enterprise solutions due to the built-in Grizzly release of OpenStack in this version. Of course, OpenStack can be downloaded by Ubuntu 12.04.2 users as well. Still businesses that are into open source and are investing in their cloud infrastructure, whether the business be dealing with financial instruments or retail, would do well to take advantage of the features offered by Ubuntu 13.04.
