Originally presented Friday, February 16th, 2018.
As a developer evangelist, you will often be called upon to speak at a variety of events from hackathons to meetups to company all-hands calls to large conferences.
An invaluable skill in the evangelist’s toolbox is the ability to quickly learn a technical topic and then teach/explain it to audiences of varying technical expertise.
Security researchers recently found and disclosed details about a chip flaw present in most modern CPUs.
Explain Meltdown and Spectre: what are they, how are they different, how do they work, and why are they scary?
You can choose any format you’d like: PowerPoint deck, rap lyrics, whiteboard coding, no slides whatsoever, it’s completely up to you.
A stellar presentation will address the widest possible audience: everyone from a non-technical salesperson or your grandmother to a senior engineering director or CTO.
Notes from slides can be found on my website: https://fvcproductions.com.

processors
tricks processors into executing instructions
they should not have been able to
grants access to sensitive information from
cached memory
33. • Impacts mostly Intel CPUs
• Attacker can access all physical
memory, including kernel
memory which results in
privilege escalation
• Mitigated through patches but
this can reduce performance for
certain workloads
• Impacts Intel, AMD and ARM CPUs
• Uses speculative execution to trick
other applications into accessing
arbitrary locations in memory
• Patched with so!ware updates but
difficult to remediate and
extremely pervasive
34. • Impact Intel chips
• Take advantage of speculative execution
• Remedies have bad side effects
