Usability: Big blunders  Often when I’m searching information about certain subjects I’ll come across websites I’ve never used before. However, all necessary information isn’t usually on the same page. Then it’s needed to find the other page, but to my surprise, many of these websites don’t have a search function.  It’s very disappointing when you know exactly what you’re looking for but can’t be bothered to look at how the website’s structure works and how to navigate it. I’d identify myself as a search-dominant user, as Jakob Nielsen defined it. It’s very frustrating when websites aren’t easy to use and common useful features aren’t available.    Usability: Content supporting images & videos  Supporting your text with images and videos.  Pictures/videos are not only important to attract the attention of your visitors, Google also finds pictures very important. Images make your content easier to read and pages that are well viewed and rea...

Deezer: Business Model Deezer utilizes a freemium-type business model. The app is available for free to download on a big variety of platforms, such as Android, iOS (including MacOS) & Windows (10). However, without paying a monthly subscription, only a limited number of features is available. It uses the same easy to navigate GUI (Graphical User Interface) as the premium subscription for comfortable usage, which makes it appealing to many people. However, in this free version, only a low audio playback quality is available, you can’t download your playlists and after every few songs you play there is an ad, either about how you can benefit from paying the monthly subscription, or from a sponsor. When you pay the subscription, you get access to all features for a reasonable price. This business model is a perfect method to get many people to download your app, as it is free, while also making a ton of money as people will easily get annoyed by all ads which means they...

  Review on Eric S. Raymondi Hacker-HOWTO.   The poem is nice, it describes the path you should follow to become a hacker perfectly. Learn from the best, practice, and become a professional yourself. To be recognized as a hacker and gain respect, I think it is natural to believe you should always share your precious knowledge and in turn preserve other’s knowledge. To achieve your dreams, you cannot give up. Even if you must perform the same task repeatedly, you continue. It may be boring, but it will pay off in the end. I do believe however, that as much as you can develop your own instinctive hostility towards censorship and so on, you cannot break the law. In my opinion the law should always be respected. Practice and dedication are key for success. Python is a very good choice when it comes to learning your first programming language, however, C# or C++ can be much more powerful. The article is a bit outdated from my point of view, Java may still be commonly u...

James Gosling    James Gosling completed a PhD in computer science and contributed to software innovation. Gosling was born in 1955 near Calgary in Canada. He invented the Java programming language, the first programming language which was able to adapt to highly distributed applications and is designed to work with the Internet. He is the father of the programming language which changed the world forever. He is currently a chief technology officer of Sun Microsystems, which he joined in 1984. In the 90s Gosling founded the Green project, which eventually was renamed to Java. The aim of the software he created was to work on as many platforms and devices as possible without it requiring customization each time. Despite the fact most of the technology developed by Gosling within project Green was never released, he saw some underlying principles would be very handy for the current Internet era. Java was officially launched in 1995. The original design, compiler and...
