Today we have a good mix of articles. First, we have an interesting bit of social engineering from Graham Cluley and how to get access to an email account based on someone’s mobile number. Next, Pat Kua talks about the role of the tech lead and their circles of responsibility. Lastly, there are three cool articles in the performance section about NGINX performance with thread pools, using HAProxy for loadbalancing and predicting application workload.

As always, enjoy today’s items, and please participate in the discussions on these sites.
