The journey began with the growing pains of scale at YouTube around the time of Google’s acquisition of the video service. This episode explores ideas about topology management, sharding, Paxos, connection pooling, and how Vitess handles large transactions while abstracting complexity from the application layer.

In this episode, Ori Mankali, senior VP of engineering at cloud security startup Akeyless, speaks with SE Radio’s Nikhil Krishna about secrets management and the innovative use of distributed fragment cryptography (DFC). In the context of enterprise IT, 'secrets’ are crucial for authentication in providing access to internal applications and services. Ori describes the unique challenges of managing these sensitive data, particularly given the complexities of doing so on a large scale in substantial organizations. They discuss the necessity for a secure system for managing secrets, highlighting key features such as access policies, audit capabilities, and visualization tools. Ori introduces the concept of distributed fragment cryptography, which boosts security by ensuring that the entire secret is never known to any single entity. The episode explores encryption and decryption and the importance of key rotation, as they consider the challenges and potential solutions in secrets management.

Itamar Friedman, the CEO and co-founder of CodiumAI, speaks with host Gregory M. Kapfhammer about how to use generative AI techniques to support automated software testing. Their discussion centers around the design and use of Cover-Agent, an open-source implementation of the automated test augmentation tool described in the Foundations of Software Engineering (FSE) paper entitled “Automated Unit Test Improvement using Large Language Models at Meta“ by Alshahwan et al. The episode explores how large-language models (LLMs) can aid testers by automatically generating test cases that increase the code coverage of an existing testing suite. They also investigate other automated testing topics, including how Cover-Agent compares to different LLM-based tools and the strengths and weaknesses of using LLM-based approaches in software testing.

Cody Ebberson, CTO of Medplum, joins host Sam Taggart to discuss the constraints that working in regulated industries add to the software development process. They explore some general aspects of developing for regulated industries, such as healthcare and finance, as well as a range of specific considerations that can add complexity and effort. Cody describes how translating regulatory requirements into test specifications and automating those tests can help streamline software development in these regulated environments.

I recently watched an inspiring talk given as part of the TED 2008 conference by Dave Eggers, a philanthropist and teacher-at-large (as they describe him). The talk shows ways in which dedicated one-to-one teaching can be provided to pupils who would not normally have access to this sort of personal tuition. What's more, the students seem to lap it up.

The successful and growing network of professionals volunteering their time to shine their light on local students of all ages is only part of the story. His novel approach to teaching and the way he makes learning fun should be an inspiration to all of us.

As Time puts it: "Many writers, having written a first best-seller, might see it as a nice way to start a career. He started a movement instead."

Have you been interested in taking a MOOC (Massive Open Online Course), but don't know where to find one or how to get started?

Class Central is a free MOOC aggregator that provides links to a wide variety of courses from universities like Stanford, MIT, Harvard, etc. (offered via Coursera, Udacity, edX, NovoED, and others).

The site allows you to search for MOOCs according to the course name, instructor, subject, start date, length of course, and course provider. Class Central also offers a "MOOC Tracker" service that will send you email notifications when a MOOC that is of interest to you becomes available.

MOOCs are a great idea for your students if your school doesn't offer advanced courses for a particular subject and they are also great resources for instructors and others. Try one and I think you will find out how they can be a benefit to you. I did!
