Install and Setup Shinken Network Monitor on Raspberry Pi

Image
Install and setup the latest version of shinken Network Monitor for a home or small business.  At work, my team develops the software for more than 75 server classes, with over 300 instances in multiple data centers and points of presence. There is an experienced operational team that monitors and keeps these servers running 24x7. I don't have anything close to their knowledge or expertise. Besides myself, I have no one supporting my home network. And, I want to spend zero time monitoring and maintaining my home network.

VPN servers are a great way to make sure your connection is secure and safe specially when you are connected to open or shared Wifi network.

The Critical Importance of Documented Risk Assessment

Image
In April of 1912, Captain E.J. Smith said, “Never in all history have we harnessed such formidable technology. Every scientific advancement known to man has been incorporated into its design. The operational controls are sound and foolproof!” This quote went on to become synonymous with one of history’s greatest failures to adequately assess risk: the sinking of the Titanic. A contemporary example of a poorly documented risk assessment process is the current water crisis in Cape Town, South Africa. With conversations into the longevity of Cape Town’s water beginning from as early as 2012, how is it possible that Cape Town has become the first city in the world to run out of water? The simple answer to an incredibly complex problem is this: The strategy to prevent such a crisis was insufficient and poorly documented.

Everything you know about giving feedback at work could be wrong

Image
Management guru Marcus Buckingham has a bone to pick with one of the prevailing trends in management wisdom — that companies need to get a lot better at giving tough, candid feedback, and need to do it a lot more often. As indicative of the trend, he points to recent popular books like Bridgewater Associates CEO Ray Dalio’s “Principles” and Kim Scott’s “Radical Candor”, the proliferation of employee survey tools and feedback apps like 15Five and news reports about tough internal cultures like the ones at Amazon or Netflix.  But in a new article in the Harvard Business Review called “The Feedback Fallacy”, which offers a preview of his book to be published in April, Buckingham and his co-author, Cisco executive Ashley Goodall, argue managers are getting it all wrong. Managers who focus so much on candid feedback are ignoring research that shows how hard it is for people to rate the performance of others, and how difficult it is to standardise and homogenise what “excellenc…

New RIPE Atlas Version 4 Probes

Image
The long wait for the new RIPE Atlas probes is over. Here's a quick look at the new devices and the work that went in to getting distribution back on track. In March last year, we released an article about delays in the distribution of RIPE Atlas probes. The short version - when the model we used for the current generation of probes went out of production, we hit inevitable delays in dealing with applications and informed the community accordingly.
