Tech interviews are weird and wacky. How did they get this way, and how SHOULD they be? Jeremiah Peschka joins us to discuss.

There are lots of jobs for data folks. In this episode, I'm discussing three hot job titles: Database Administrator (DBA), Database Reliability Engineer (DBRE), and Data Engineer (DE) To see the venn diagrams I made for these roles, visit https://catalyzesql.com/blog/1/01/01/dear-sql-dba-data-roles-dba-dbre-de/

I wrote a blog post inspired by Stephen Vakil 's excellent suggested interview question, but I inverted it: When should you NOT choose SQL Server to store your data? My thoughts: * When you don't actually need a database * When you're not using structured data * When you want pure analytics, or something other than a workload involving OLTP * When you need to write to multiple nodes for a single d...

It's Down Tools Week at Redgate. I share what "Down Tools Week" is, what I'm working on this week, and why I think it's a terrific experience for fostering creativity, innovation, and teamwork. In closing I share some thoughts on variations of this kind of project which you might use in your own organization, whether you are a developer, DBA, or have another role.

Many people use entrenched processes for database development that have been in place so long that it's hard to imagine doing it any other way. In this episode, I share three things that should NOT be normal for database development-- but which are incredibly common. This episode is inspired by the book, "The Unicorn Project", by Gene Kim.

I'm not an expert on collation in SQL Server, but there are a few important facts which I've had to learn the hard way. In this episode I share the basics, along with helpful resources to learn more. One small localization correction: the default collation on a SQL Server install will be "the oldest available version that's associated with each specific locale." So if your Windows installation has...

You're a DBA, and your development team is all-in on doing DevOps, and they want to include the database. Should your DBA team limit the permissions or options for automation? Or should you instead re-think how your two teams work together?

I've been working as an 'Evangelist' at Redgate for close to six months now, and one question keeps coming up: what exactly does an Evangelist do at a software company? In 21 minutes, I explain the core mission of Evangelists, and why I think being part of the sales process is an important part of the future of software evangelism.

Jobs change over time, and database administrator jobs are no different. In this 35 minute recorded Twitch livestream (my first ever!) I talk about threats to DBA jobs and the related opportunities.

In this session, I discuss scrum, continuous deployment, test driven development, DevOps, and related concepts. I close with a quick discussion of why Database Administrators and Developers should care about DevOps.

So you've got an employee agreement in front of you: now what? In this 23 minute episode, I talk about practical steps you should take to make sure that you understand the terms of your contract, and how to potentially negotiate the terms.

When you take a new job in software engineering or in IT, within the paperwork there often lurks an employee agreement: a contract between you and your employer. In this half-hour live episode we'll talk about why these contracts exist, and multiple anti-patterns you should avoid. This is the first of a two part series. In the next episode, we'll talk best practices for understanding and negotiati...

This week I discuss a question that I've gotten in many forms over the years - a lot of the scenarios are so specific that it's hard to keep them anonymous, but they can be generalized as a bigger problem: how do I deal with being responsible for things that I can't fully control? DBAs have huge responsibilities, so this is a common, frustrating scenario. In this episode, I talk about a few times...
