Essilen Research Free Video Series on Hiring

Modern tech companies understand that hiring is the most important on-going activity they undertake. However, a lot of companies still do their hiring in an ad-hoc way. Thrown-together job specs, random resume screening, unfocused interviews, and a lot more. The result is a process that doesn't get you the best employees you could. World-class tech companies do things very differently. In Essilen Research's video series on tech hiring, you'll learn the secrets that the best companies use to hire the best engineers, developers and designers.

We take you through the hiring process from start to finish. Learn how to write the right job spec. How to screen candidates efficiently, effectively, and without bias. Learn how to train interviewers so everyone's on the same page. No more arguments at the hiring meeting! And there's more: how to offer and close candidates, so they don't slip through your fingers. And of course, how to onboard new-hires the right way so they hit the ground running.

Essilen Research has decades of experience starting, building, running, and scaling great tech organizations. We've conducted thousands of interviews as hiring managers, hired hundreds, and trained dozens of interviewers ourselves. There really IS a better way to do tech hiring and this video series will start you on the path. Level up your tech hiring!

The DynamoDB Book: An Interview With Alex DeBrie On His New Book

 

You know nothing about DynamoDB. At least that’s what I realized the first time I heard Rick Houlihan give his now infamous talk at AWS re:Invent 2018 on Amazon DynamoDB Deep Dive: Advanced Design Patterns for DynamoDB.

In that talk Rick revealed for the first time the inner arcana of single-table design. Minds were blown. Weaknesses were revealed. Futures were changed.

As a mere novice in the ways of DynamoDB I realized there were many levels of understanding needed before one could become a true AWS Data Hero. For that we need a guide.

Our guide on the Hero’s Journey that is mastering DynamoDB is a wise young wizard named Alex DeBrie. Alex wrote what you might consider to be the Gnostic Gospels of DynamoDB: The DynamoDB Book.

 

 

You will know something after reading this book

But it's more than just a book. You can’t buy it on Amazon. Instead, Alex uses Gumroad to offer packages at three different price points along with a team option. Each level provides additional content:

  • Basic package ($79). A 450 page book and six cheatsheets.
  • Plus package ($129). 60-page Analytics supplement guide. 60-page Operations supplement guide. Five deployable code implementations.
  • Premium package ($249). Video walkthroughs of every chapter.

Use the code "HIGHSCALABILITY" at checkout and you’ll shave off $20 for Basic, $30 for Plus, and $50 for Premium. You’re welcome.

When Alex asked for advice about what to include in the book, I made a big deal about including complete working code examples. Alex delivered. So I thought it was only fitting that I buy the Premium package.

But it’s so much money, you might complain. As someone who has made not much money writing a book I have some idea how much effort Alex put into creating these materials. It’s a lot of work. As a profession we must be willing to pay for our tools. So as a professional programmer wanting to create professional products—I’m very happy with the result. Here’s why.

What’s great about SQL is you can find an answer to damn near any question you have. Not so with DynamoDB. Working code examples are rare.

I remember Rick talking about using “between” when making queries. Never heard of such a thing and it took me forever to find a complete working code example of what he was talking about. Don’t even talk about the documentation. What you find are ridiculous command line examples like “aws dynamodb query…” What use is the command line for this sort of stuff?

Show the code! And Alex does.

I think you’ll find the 5 code examples—Big Time Deals, E-Commerce, Github Migration, Github Node, and Session Store Node—worth the price of admission. First, they tackle complex domains so they might already solve a problem you’re having. That’s gold. Second, you’ll learn a lot by just reading the code. As a not so great Javascript developer I know I learned a lot.

What about the Holy Grail of single-table design? If you have that sneaking suspicion you’re using DynamoDB incorrectly and you’ve tried to learn single-table design before, but got frustrated, Alex has your back. The book is filled with clear examples backed by strategies for various use cases.

Against my expectations the videos turned out to be very useful. Alex’s tone was great. It was just like he was next to me explaining what he was doing. And that’s exactly what you want from a teaching product.

Here's my email interview with Alex DeBrie on The DynamoDB Book. Enjoy.

Free Google Book: Building Secure and Reliable Systems

 

Google added another book into their excellent SRE series: Building Secure and Reliable Systems. It's free to download, so don't be shy. 

It's not short: 557 pages and 21 chapters! So what's it about? In short it's about "reliability through the lens of security."

In long, Ana Oprea, one of the authors, gave a good overview. anaoprea:

There are multiple questions about what this book is about, who it's for and what might be relevant for me. We recommend going through the Preface to get answers to these questions. Copy/pasting a few paragraphs: "In this book we talk generally about systems, which is a conceptual way of thinking about the groups of components that cooperate to perform some function.

We wanted to write a book that focuses on integrating security and reliability directly into the software and system lifecycle, both to highlight technologies and practices that protect systems and keep them reliable, and to illustrate how those practices interact with each other.

We’d like to explicitly acknowledge that some of the strategies this book recommends require infrastructure support that simply may not exist where you’re currently working.

Because security and reliability are everyone’s responsibility, we’re targeting a broad audience: people who design, implement, and maintain systems. We’re challenging the dividing lines between the traditional professional roles of developers, architects, SREs, systems administrators, and security engineers.

Building and adopting the widespread best practices we recommend in this book requires a culture that is supportive of such change. We feel it is essential that you address the culture of your organization in parallel with the technology choices you make to focus on both security and reliability, so that any adjustments you make are persistent and resilient.

We recommend you start with Chapters 1 and 2, and then read the chapters that most interest you. Most chapters begin with a boxed preface or executive summary that outlines the following:

  • The problem statement
  • When in the software development lifecycle you should apply these principles and practices
  • The intersections of and/or tradeoffs between reliability and security to consider

Within each chapter, topics are generally ordered from the most fundamental to the most sophisticated. We also call out deep dives and specialized subjects with an alligator icon."

I've only had time to browse through the book. One thing I like is they use as examples actual security and design issues they've experienced at Google and then explain how those were solved. Google has problems, just like you.

One thing I always dislike about security books is that empty feeling I get when I go to write that next line of code and I realize I still don't have any idea if that line is secure or not. Even though Chapter 12 is on Writing Code, I'll still get that feeling. Perhaps that's just the nature of the beast. It will take much more practical work before security and reliability can truly become inherent properties of all information systems.

This book is a top to bottom look at a complete organizational response to security and reliability. It's not for the meek:

For those who are passionate about security and reliability, we conclude with the following advice: your ability to work across knowledge domains and embed expertise in the right places is key to your organization’s success. Security and reliability need to be an integrated part of the entire computing environment. All these pieces must work together in harmony to solve problems. No checklist or silver-bullet advice we could give can compensate for your own ability to help your organization flex and grow as the nature of the security and reliability challenges it faces evolves.

One Team at Uber is Moving from Microservices to Macroservices

 

There may be an undiscovered tribe deep in some jungle somewhere that hasn’t made up their mind on microservices, but I doubt it. People love microservices or love to hate microservices. There’s not much in between.

So it means something when even a team at a company like Uber announces a change away from microservices to something else. What? Macroservices. But we’ll get to that. Think what you want about Uber the company, but from a software perspective Uber has been a good citizen.

Gergely Orosz, an Engineering Manager on the Payments Experience Platform at Uber, in a tweet signaled a change in architectural direction:
