  • Excellent Free Tutorials to Learn Markdown

    Markdown is a plain text formatting syntax created by John Gruber in 2004. It’s designed to be easy-to-read and easy-to-write.

    Readability is at the very heart of Markdown. It offers the advantages of plain text, provides a convenient format for writing for the web, but it’s not intended to be a replacement for HTML. Markdown is a writing format, not a publishing format. You control the display of the document; formatting words as bold or italic, adding images, and creating lists are just a few of the things we can do with Markdown. Mostly, Markdown is just regular text with a few non-alphabetic characters included, such as # or *.

Like other popular commands, such as apt or vim, an entire ecosystem of tools has grown up around it. In fact, Debian’s stable repository alone lists over 60 secondary tools whose names start with “git” and around 70 with unique names.

  • Zydeco::Lite

    Today I released Zydeco::Lite, a re-implementation of Zydeco but just using standard Perl syntax. So for example, class { ... } becomes class(sub { ...});.

    This has the advantage of much faster compile time, similar run time speed, fewer dependencies, and compatibility with older versions of Perl before the keyword API was introduced. Of course, in some circumstances these aren't important concerns, so the nicer syntax of the full Zydeco will be preferred.

7 Amazing Linux Distributions For Kids

Linux is a very powerful operating system and that is one of the reasons why it powers a lot of servers on the Internet. Though there have been concerns about its user-friendliness which has brought about the debate of how it will overtake Mac OSX and Windows on desktop computers, I think users need to accept Linux as it is to realize its real power. Today, Linux powers a lot of machines out there, from mobile phones to tablets, laptops, workstations, servers, supercomputers, cars, air traffic control systems, refrigerators, and many more. With all this and more yet to come in the near future, as I had already stated at the beginning, Linux is the operating system for future computing. Because the future belongs to the kids of today, then introducing them to technologies that will change the future is the way to go. Therefore they have to be introduced at an early stage to start learning computer technologies and Linux as a special case. One thing common to children is curiosity and early learning can help instill a character of exploration in them when the learning environment is designed to suit them. Having looked at some quick reasons why kids should learn Linux, let us now go through a list of exciting Linux distributions that you can introduce your kids to so that they can start using and learning Linux.
