Creating vs. Maintaining 01/29/2025

Creating vs. Maintaining If your job as a developer or DBA has been like mine, it's a constant stream of requests to change something, often without enough information and short deadlines that create a bit of stress. There's always more work to be done, and while it might be a great job, you're often trying to finish something quickly enough to get to the next thing. In this mode, how often do you think about creating (or modifying) the thing you're working on for today vs maintaining it for tomorrow. In other words, do you consider how easily your work can be understood, is documented, is designed to allow for flexibility, and can be enhanced without many (any?) side effects, or anything else.

Can You Become a More Productive Engineer? 01/24/2025

Can You Become a More Productive Engineer? The short answer is of course, most of us can learn and improve our skills to become better developers, engineers, DBAs, etc. While we might not be able to become the 10x engineer that many aspire to be, we can certainly become a better employee inside of an organization. There's a piece on becoming a more effective engineer, which is actually titled . It a piece from an engineer that started with a : The text was:You can either complain and pontificate on Twitter on how the tech industry *should* ideally work, or you can learn how your org *really* works and what’s rewarded, and optimize for that. Or quit and find another job. This might sound cynical - but it’s what it is. That sounds a little harsh, but the reality of how your org works or is structured or interacts is a reality. We all have hindsight to look back and wish someone (including us) had written code better. We might be sure if we could change one thing, or add/remove someone else, or make some other change, then things would be better. We might feel that there is a simple solution. Those things might be true, but they aren't the reality of the situation. Read the rest of /episode/index/show/voiceofthedba/id/34873945

Simple(r) Coffee 01/13/2025

Simple(r) Coffee Starbucks has too many order combinations. about the challenges for their new CEO notes there are over 170,000 combinations of things customers can order. As someone who has visited a store often and stood behind someone placing an order, that sounds like an accurate number. Sometimes I hear people order things to drink that I had no idea were even possible. When there are too many choices, sometimes there can be a delay as the person tries to process the information and make a decision. Some people can't make a decision. Others enjoy the variety and keep making different decisions each time. That's fine if you're visiting a restaurant, but it's less useful if you're building software.

The Rise of Data Centers Centers 01/06/2025

The Rise of Data Centers Centers For the last few years, we've seen no shortage of cloud migration stories and felt pressure from management who wanted to migrate our systems to the cloud. It seems that almost everyone I speak to has a story of having to move a system out of their owned or leased data center into a public cloud from some vendor. A lot of this is the movement of VMs from one place to another, which has me scratching my head. If we're just running VMs, surely we can do this cheaper in our own data center. Perhaps, though there are a lot of costs to setting up or running a data center, and it's not easy getting a system in place that allows a bit of self-service for our customers. Especially while ensuring that images used are properly patched and secured, while ensuring lots of easy connectivity to storage that can be reconfigured easily. It might not be worth the effort for a few dozen VMs, but if you have hundreds of systems, maybe it is. Read the rest of /episode/index/show/voiceofthedba/id/34492535

Comforting Habits 12/20/2024

Comforting Habits I was chatting with a friend recently about routines and some of the helpful or silly things we do. I mentioned that when I played adult baseball, we often had Sunday morning games and a routine of mine was to drive to town, stop at a 7-11, and get a large cup of coffee and an apple fritter. It was a comforting habit that I still have today, often stopping when I have a morning flight to do the same thing in the way to the airport. Only in Denver though, not when I'm flying out of other cities and returning home. Read the rest of /episode/index/show/voiceofthedba/id/34320450

Big Data or Small Data 12/18/2024

Big Data or Small Data I went to San Francisco for , a conference sponsored by The premise of the event was that smaller sets of data are both very useful and prevalent. The speaks to me, as I am a big fan of smaller sets of data for sure. I also think that most of the time we can use less data than we think we need, especially when it's recent data. That often is more relevant and we end up with contorted queries that try to weight new or old data differently to reflect this. Maybe the best line for me is this one: Bigger data has an opportunity cost: Time. Read the rest of /episode/index/show/voiceofthedba/id/34320430

Learning to Grind 12/16/2024

Learning to Grind When I was younger, I had a variety of jobs, but in most of the positions I had to work hard for stretches. Really hard, as in more than 8 hours a day or 40 hours a week. Often as I was starting a new position, it took some time for me to develop some understanding, some skill, and some muscle memory. In some jobs, especially in restaurants, I also had to build the physical skills to be on my feet for many hours. In technology, I've often found myself unsure of how to approach a new position, aware I had knowledge gaps about how things worked, and often, I was naïve or ignorant of some piece of technology my employer used. Even at jobs where I started as a developer or DBA on a known platform (ASP or SQL Server), I sometimes encountered some aspects of the technology that I hadn't used in the past (like clustering).

The AI/Human Spectrum 12/13/2024

The AI/Human Spectrum I was asked this question recently: is it more likely that AI will replace humans or assist them in their work? It's a good question. If you think about the way AI is being hyped in 2024, many people think AI is, or will soon be, replacing people and we need less of them in work. I guess the simplified view is that AI can do the jobs of many people, but I'm not sure the world is that simple. What I think is more likely is that AI becomes a lever that assists a few people in getting more work done and potentially replacing other, less knowledgable humans.

Continuous Learning 12/11/2024

Continuous Learning It seems there's quite a dichotomy in the technology workforce. On one hand I hear about the Great Resignation where many employees are leaving their jobs because of RTO (return to office) mandates or some other dissatisfaction with their job. On the other, I've seen quite a few people who were laid off and are struggling to find new positions. On the third hand, there is no shortage of companies who report they are struggling to find and hire talented people for some positions. I don't quite know what to think, but I do know that employment seems to be harder to come by. If you are looking for a job, I believe you need your own sustainable learning plan. If your organization can't find qualified talented staff, then the organization definitely needs a continuous learning plan. Read the rest of /episode/index/show/voiceofthedba/id/34320410

Distributed Monoliths 12/06/2024

Distributed Monoliths I was watching a video called . In it, the person being interviewed said that a lot of people really have a distributed monolith. That caught my eye since I've worked with a number of customers who are trying to adopt microservice architectures for their applications. I think this is less a performance/scaling choice than a reworking of their software development teams, and I'm not sure they will end up with a better system. What is ? I am not an expert, but this appears to be a place where all the services still depend on each other. For example, I might have a service getting user profile info that an app calls, with another service getting previous orders, and a third service that returns inventory. In a monolith, if any of these are down, the others don't work. In a distributed monolith, these might be built independently, but perhaps the core app/web page still requires all these to be working to show the user something.

Reducing the Cycle Time 12/04/2024

Reducing the Cycle Time There are lots of software development methodologies. lists a few, among them waterfall, agile, iterative, rapid, and more. What's been interesting to me is that the process of deciding what to code and then whether it works doesn't change much between different ways of building software. Instead, the cycle time between when we ask a client what to do and when we deliver it changes. The more agile/lean we are, the lower the cycle time. The more waterfall-ish, the larger the cycle time. I guess that analysis and breakdown of problems into work also changes, as the scope in modern DevOps styles of development is smaller (more contained) than in waterfall.

Doing a Little Research 12/02/2024

Doing a Little Research I've been very pleased with the direction of SSMS the last few years. As it's been separated from SQL Server releases and gets updated more often, I think the changes from v17 though v20 have been improvements. There are still issues, but it's been better. Now we finally have SSMS moving to a modern shell with and I'm excited to see how this changes the future of our tooling. However, the PM for SSMS, Erin Stellato, recently asking why people don't read documentation. She also asks what you want to see in 21, so respond if you think there are holes in the SSMS docs. I think this post came about because of many responses that came from people who clearly hadn't read some documentation. Read the rest of /episode/index/show/voiceofthedba/id/34114626

Have Grace 11/27/2024

Have Grace Thanksgiving is tomorrow in the US and it is supposed to be a holiday when we give thanks for our blessings in life. My wife usually has everyone in our family tell what they are thankful for this year. I also see many people posting things they are grateful for during the month of December. Last month I was lucky enough to have dinner with Bob Ward and we were talking about some of the things we'd seen in travels, often some stressful times for ourselves or others. We've seen many people get upset or angry or have some other reaction. Both of us have some empathy for others, recognizing that we don't really know their history or experiences, and it doesn't make sense for us to get upset. If we knew those things, we might better understand the reaction that someone displays to a situation. Read the rest of /episode/index/show/voiceofthedba/id/34114546

Computer Algebra 11/25/2024

Computer Algebra I was a bit of a math nerd in high school and college. Some of you might have been as well, but I took advanced math all through high school, culminating with AP Calculus as a senior with 11 other kids (of about 320). In college, I started with Calculus III freshman year and went on to take 7 more semesters of various high level maths. One of those classes included analyzing data with linear regression, which we did with hand calculators and formulae. At , I watched a talk from on linear regression. It was a trip down memory lane, with Jeff explaining how the process worked, the flaws, and how this technique could be used to do some predictions on data stored in SQL Server. It was a great session on the topic, but I liked that Jeff showed how you can use SQL Server to do various math calculations that might be useful to analyze data. I see applications sometimes programming various formulas, but I don't often see people doing this in database queries. Read the rest of /episode/index/show/voiceofthedba/id/34114446

How Do You Patch 100 Database Servers? 11/18/2024

How Do You Patch 100 Database Servers? In most of the organizations I've worked for or consulted with, patching was always a challenge. Patching hasn't usually been given a priority and is often skipped when operations staff is busy. This has resulted in lots of un-patched, or slowly patched systems. I assume this is one reason Microsoft continues to release RTM-GDR patches because some people won't patch at all unless there are critical fixes. I also know that much of IT management sees patching systems like patching parking lots. Needs to be done, but tomorrow, after we do other important work today.

Do You Want a Microsoft Solution? 11/15/2024

Do You Want a Microsoft Solution? Microsoft constantly releases new features and products in the data platform space. Many of us have seen the SQL Server product grow in new ways, some of which are very useful to us. As an example the changes from log shipping to clustering to Availability Groups has improved our HA/DR options as well as the capabilities available to us in different situations. With that in mind, I saw someone recently that wanted to deploy SQL Server on Kubernetes, which is something that could be a very interesting way of managing your different systems. However, this individual wanted to know when Microsoft would release their own supported solution with a Microsoft operator to manage the instance. There is , but no official operator.

Separate Reads 11/13/2024

Separate Reads Recently I was watching a presentation on how to scale performance in your SQL Server environment and one of the suggestions was setting up Availability Groups (AGs) and having read-intent connections that would query the secondary and not the primary. It's not a bad idea, and and make it easy to implement. The pattern of using multiple connections in an application, one for reads and one for writes, has been suggested often. However, in practice, I've rarely seen this work. Apparently having a connection variable, named dbConn, for writes and a second one, named dbConnReadOnly, for reads is too complex for most developers or teams.

Time to Change Your Team 11/10/2024

Time to Change Your Team I assume most of you work with others in a team. Even if you are the data specialist and others work on different technologies, you still have a team. How long has your current team been together in this form? Have you had a stable team that might have grown, but the rest of the individuals and roles/responsibilities stay the same? Or has your team changed makeup, roles, responsibilities, or something else? I don't see a lot of organizations that change their team structures often. There may be people who come and go from a team, but the core structure remains the same. Even when your company might reorganize a bit, often it's teams that shuffle between managers, but mostly remain the same. There certainly are exceptions, and some large orgs (Microsoft, Amazon, etc.) regularly shuffle lots of people around, but I'm not sure the teams change their makeup or their mandate much.
