In the railway and signalling standard from CENELEC, i.e. the EN 50126 or 50129, it is mentioned that one of the strategy (if I am not mistaken) for designing a safe system is through the use of Defence in Depth. My understanding of this is that the there are various ways a function can be…
It just occured to me that my children are getting bigger, i.e. growing and becoming teens, that it seems a bit disjointed with my view of my own life. I have been working over a decade now so it seems plausible to imagine how I would work or how my career would be in another…
This report from Amnesty UK highlights that genocide is done on Gaza and Palestine. It is disheartening to read but I applaud the writers. Against the perpetrator, may Allah met justice on you. Hollywood has always been showing the brutality of WW1 and WW2, showing how people did bad things at that time. That time…
Someone asked recently on Linkedin, why aren’t railways using GPS for their train positioning. Here’s my answer below: 1. GPS is limited by infrastructure and obstruction2.

Here’s a youtube post that summarizes it quite nicely. https://www.youtube.com/watch?v=8cEhCx8pwio What is BNF? It is a way to describe how software language can be written,…
I saw a post on LinkedIn today telling how a person who got a 45% increase in salary and a lot of benefits such as working remotely, left the company, after being called useless and exposed to toxic environment and management. The post then went on to say that people left not because of the…
Recently I’ve been working on a few projects that requires understanding some very wide and deep topics, particularly EULYNX and SSI.
