As per latest reports, major enterprise applications are all set to begin multi-year migration from the current on-premise software to the much talked about cloud computing environment.
One of the main reasons behind this is said to be a probable upcoming recession.
Now, the big question is whether to believe all these talks or go with the current flow. Read the rest of this entry »
Selection Sort is also used for sorting smaller size array and simple as bubble sort but is better technique than that. You will have to select the smallest element in the array and then position it at the head. This process is iterated for the rest of the elements in the array, i.e. the second smallest element is placed below the first and so on.
Once the position of the element at the head is fixed, it will be ignored for the successive iterations, which in-turn decreases the time complexity and hence selection sort is faster than Bubble sort as well.
Here’s the code snippet for selection sort algorithm implementation in C programming language – Read the rest of this entry »
We are now surrounded by embedded systems, like cell phones, remote control, computers, watches, and what not, even the SUVs we drive are equipped with such systems. Almost everything in this world comes incorporated with embedded systems.
What is an Embedded System
An embedded system is a concept, which consists of programming logic hard coded or burned on the circuits to make them function in particular direction or performing different tasks.
The logic drives the circuit towards a particular goal. The students learning embedded systems can opt for jobs in various files like programming, chip designing and architecture, and even interfacing of different chips together. The embedded systems field has seen many improvements in the past and will continue to see in the future.
Some Interesting Figures
There is a constant increase in demand for professionals with embedded training and it is believed to touch millions by the end of 2015. The constant incorporation of embedded systems in electronic devices has created a demand among major companies to look for specialists in the domain.
The massive boom in sales of Embedded Systems have made it to three hundred billion sets of chip to be sold and the highest use was in mobile phones with up to 60% of total sales.
However, there has been a gradual change in the sales format and the desktop computers are increasing to gain more share of sales. The situation of economy has driven towards the use of DRAM and FLASH, especially among the consumers for the field of application.
The plan proposed by ITRS says that the SOC cost will reach more than one million US dollars in the next three years. The two third of the cost is coming from the study and research of embedded systems apart from the man power used. The chip is independent from the software and the software itself takes away the large ratio of over embedded systems development.
Large-scale systems are approaching petabytes, and grid computing in the buzzword today.
Latest Developments in Embedded Systems
Grid Computing: It’s a CS paradigm concerned with enabling virtual organizations.
It is mainly classified into -
Research is going on in the areas of interoperability between mobile and heavyweight grids, basically to help two grid systems communicate efficiently.
Developments in VLSI
The processors have undergone lot of improvement changes, and they’re still undergoing radical changes resulting in ultra fast processors. As the growth is exponential, the processors which used to be of speed less than 500 MHz now tend to go beyond 10 GHz processing speed.
Gone are the days when chips used to be of palm sizes and now it is barely seen by naked eye.
The parallel and multi layered architecture has made it possible to reduce itself in size and gain performance boost than ever before. It is expected to reach speed like 20 GHz by the end of 2024, but as the technology is gaining speed very fast, we can grab such processors by hand around 2015.
The future of embedded systems, and VLSI technology is definitely very bright, and they’re definitely going to change our day-to-day life over the next 3-5 years!
The Apache security HTTP Server is one of the most popular servers worldwide. Apache hosting has a number of advantages, right from its worldwide acceptance, down to presence of a massive developer community to seek assistance.
The security levels involved are always high, and Apache web server boasts of flock of features that aren’t available on all the web servers. Apache supports SSL and TSL, authentication modules, a proxy module, server-side programming language, common languages interfaces, and even rewrite engine.
Apache hosting is extremely popular in case of VPS, since you can view remote logs, and use free scripts effortlessly to generate traffic reports and much more. There are plenty of other benefits associated with Apache hosting, but still its popularity has decreased drastically with emergence of IIS7.
Benefits of IIS7 over Apache
IIS 7 came out with several improvisations over Apache, and plenty of firms considered migration from Apache to IIS, to make use of the new architecture, not to mention the obvious long term cost effectiveness of the Windows Server platform.
However, the functionality of IIS way too different from Apache, and it would take more than a business decision to make a big shift from Apache to IIS, especially for the developers who’re accustomed to working with Apache.
Working With Apache.
As everyone is pretty much aware of the fact that the days of good old static HTML sites are almost gone, and now everyone wants to build highly interactive PHP-MySQL based database driven sites with all possible functionality that provide a wonderful user-experience.
For coders, and those who work with Apache, LAMPP is an extremely popular term, which stands for
• Linux,
• Apache,
• Mysql,
• PHP, and
• Perl.
Basically, the apache web server is the core framework of your website, and Linux OS adds to flexibility and robustness, while saving your licenses cost at the same time. Mysql is one of the best open source databases, and PHP is yet another open source scripting platform that makes creation of dynamic web pages almost a snap.
To work with Apache, you require the aforementioned expertise, but to make use of Apache hosting, you don’t really need to know any technicalities.
Since we’re discussing the use of Apache and Lampp, it is essential to mention that the most popular blogging software, WordPress is almost based on LAMPP i.e. Apache, and Linux/Apache hosting is essential to support hosting of WordPress blogs. Therefore, if you’re planning to run WordPress blogs, IIS hosting isn’t going to help!
Migrating from Apache to IIS
If you need to migrate from Apache to IIS, it may sound like a daunting task at hand. But, there are a handful of resources such as ISAPI_Rewrite module from Helicon that can help you in transferring Apache’s configuration as well as URL rewrite capability onto IIS effortlessly. Similarly, you’ve got the Apache Emulator module that facilitates full scale migration of websites in few simple steps, making the migration from Apache to IIS hell a lot simpler than expected.
But, still there’s whole lot of confusion over the matter, and many companies are hell bent on using Apache, and simply refusing to make a shift onto IIS.
Updates with IIS7 Hosting Plans
The goodness of Helicon’s APE isn’t a secret any more, no wonder majority of the hosting providers are now providing this module as a part of their IIS 7 hosting plans, enticing the administrators, and business owners to make a move from Apache hosting to IIS hosting. This has definitely made the life of managers lot simpler, since the migration process has become easier than ever before. However, from business point of view, IIS7 is still new, and dumping the tested and trusted platform like Apache, and making such a big move is still a very thoughtful issue that must be handled carefully.
Additionally, Apache hosting has been admired in terms of exceptional track record in systems protection, but once again you can’t call any system to be flawless by any means.
Keeping pace with technological developments is extremely necessary, so even if you’re making a move to IIS, you must keep yourself up-to-date with latest developments. Last but definitely not the least, one must also consider the specific requirements and platform into consideration, before planning to migrate from Apache to IIS or deselecting Apache hosting services, since WordPress blogs, many open source shopping scripts, and wide varieties of applications run on Linux/Apache environment, and it would not be possible to sustain them with IIS, despite the fact that IIS7 has got a number of advantages over Apache.
