Longitude - the World of Things


Longitude a geographic coordinate that specifies the east-west position of a point on the Earth's surface and is best determined using time measurements. Galileo Galilei proposed that with accurate knowledge of the orbits of the moons of Jupiter one could use their positions as a universal clock to determine of longitude, but this was practically difficult especially at sea. An English clockmaker, John Harrison, invented the marine chronometer, helping solve the problem of accurately establishing longitude at sea, thus revolutionising safe long distance travel.
Harrison’s watches were rediscovered after the First World War, restored and given the designations H1 to H5 by Rupert T. Gould.
Important dates: 1759 (Finished manufacturing of H4), November 2017 (launching of PowaINFRA - an awesome Internet of Things).

The importance of the major incident process

ITIL mentions the Major Incident process as a special case of the incident management process as well its close relationship to problem management.  However, the Major Incident process requires greater clarity and specification as in many large enterprises the process is crucial for overcoming a crisis. A Major Incident typically defined as an incident with severe negative business consequences and an important duty of any designated Information Technology (IT) resources is to deal with Major Incidents in a structured manner.  We will address this important topic in a series of articles that specifically addresses the process and crisis management in general.

Using OPENDNS on a Mikrotik

At the office we use a Mikrotik which is connected via fibre to Cool Ideas .  We use OpenDNS as a Information Security tool.  It prevents ransomware and bots from becoming major incidents within the office. The router is scheduled to do a daily update via script of the OpenDNS settings.  Below is the example: :local opendnsuser "user@domain.co.za"; :local opendnspass "itsprivate"; :local opendnshost "office"; :log info "OpenDNS Update"; :local url "https://updates.opendns.com/nic/update"; /tool fetch url=($url . "\3Fhostname=$opendnshost") user=("$opendnsuser") password=("$opendnspass") mode=https dst-path=opendnsupdate.txt :local opendnsresult [/file get opendnsupdate.txt contents]; :log info "OpenDNS: Host $opendnshost - $opendnsresult";
