Explainer: should you change your password after Heartbleed? By Andrew Smith , The Open University If you’re struggling to understand the deluge of information about the Heartbleed vulnerability , you’re not alone. Some reports tell us to change all our online passwords immediately, others warn us that this could do more harm than good. There is a lot of misinformation out there. It is essential that you do not panic but nor should you be complacent. We all need a good old fashioned mix of common sense and prudence. What is Heartbleed? On many of the servers and internet web services we use, there is a free and open source security technology called OpenSSL . In simple terms, when you see the padlock beside the web page URL , you have a secure and encrypted web connection that may have been managed by the OpenSSL software.

The wheels at my university are renowned for being slow and cumbersome. However, getting a simple prepackaged course from a 3rd party with no rights issues out there has been nothing short of escargot'esqe. As of the 1st of May 2017 - we have our first Linux NAL - following the model of the relevant knowledge courses that once occupied the students of the Open University. Offering Linux is not a new notion - having offered for three years a short course in Linux that was at the time ahead of most in reaching a distance learning population. In this short time, we engaged with over 2400 students giving them all a taste of Linux. Now, with the maturity of HTML5 and some considerable insight from NDG and LPI in collaboration with Cisco Systems. We are able to offer a fully remote Linux experience. With the Linux operating system running as a web browser based cloud instance. Our first presentation of this course will have all the hallmarks of a discovery experience - while
You have to face it, in some ways we are all fish in our own personal ponds. Some of us succeed in changing the water, finding a different or more interesting pond. Yet remain a fish in water, unless we evolve, Often work takes me around the country (and sometimes the world). Part of my working ethos is to share advice, experience and a can do (rather than a cannot do) approach to qualification delivery. Yet so many seem trapped in a self created universe; a perception of what their limitations are and how they bind them in what they do. It is rare to see fish fly, but they do, it is rare to see fish survive out of water but some can. Some fish climb, to change their environment others seek bigger more plentiful ponds until they become oceans. You can't free a fish from water, that is its choice alone.
