My Guest Today
Marino Wijay gives us a view into corporate tech companies in Toronto, and shares what he’s learned about stock & investments.
Notes, Links, and Corrections
- Marino and I both attended Ontario Tech University, known then as UOIT. We went in vastly different directions thereafter.
- Marino attained a Cisco Certified Internetwork Expert (CCIE) certification, an 8-hour gauntlet of challenging networking problems. Most people do not succeed on their first attempt.
- He also mentions Juniper‘s JNCIE certification.
- The OSI model describes how computers communicate over networks. Here’s a handy picture.
- We went from high-end consumer CPUs having 2-4 cores ~2.5GHz to now 8-16 cores ~4.5GHz.
- Moore’s Law predicts that transistor count on an affordable CPU doubles every 2 years. I mistakenly said it doubled every 18 months, which I learned is a common mistake. It was David House from Intel who claimed it doubles every 18 months, not Gordon Moore.
- Moore’s prediction was made in 1975 and has been largely accurate.
- Storage Area Networks are networks or devices exclusively for the purpose of accessing storage.
- Hyper Converged Infrastructure.
- Containers provide resource isolation, but in a cheaper way than Virtual Machines. Kubernetes is a system for orchestrating containers.
- VMWare NSX
- A great insight: when developers said they wanted Software Defined Networks, what they really wanted was a software defined application platform.
- I mistakenly say that Elastic Search is written in Erlang, but I meant to say Apache CouchDB is written in Erlang. Both are high-performance technologies I use in my day job.
- Raspbian: Debian Linux for Raspberry Pi.
- pi-hole is a DNS server that blocks ad-serving domains, designed to run on the Raspberry Pi. Now even your TV and Smartphone won’t see ads ;)
- Mike from the Useless Duck Company hosted a robot-building event that I attended. Thanks Mike!
- I accidentally confused Raspberry Pi with Arduino. They’re very different!
- Jack of all trades, master of one.
- T-shaped employees. See page 46 of the Valve Employee Handbook
