A Fine Slice Of SQL Server
In this video, I cover several configuration options for tuning SQL Server backup operations. I’ll talk about what options are available and which ones are important.
This is another long video (at least for YouTube), but I cover a lot of useful information, if I say so myself.
Leave a CommentIn this video, I show how to restore SQL Server databases using SQL Server Management Studio, T-SQL, and the dbatools PowerShell module.
Originally, I had plans on covering SSMS + T-SQL in one video, and then dbatools in a second. Then I decided, well, why not just cover both of them in the same video? And this is how we get to half-hour long videos.
Leave a CommentIn this video, I show how to perform a variety of database backup operations via PowerShell, using the dbatools PowerShell module. I also show how easy it is to test a database backup using dbatools.
I finally have a video shorter than 10 minutes long. Don’t worry, the next one will blow right past that figure.
Comments closedIn this video, I cover the three recovery models available to SQL Server, describe (most of) the types of backups you can take, and spend a bit of time covering Recovery Point Objective & Recovery Time Objective.
The advice for video length that people tend to give is 8-10 minutes. I typically average closer to 15 minutes per video. This one is nearly 30 minutes long because there’s just so much information to cover, even with me repeatedly saying “Don’t worry, I’ll cover this bit in a future video.”
Comments closedI’ve started a new video series:
In this video, I explain why it is so important to back up your databases. From there, we see one technique for taking these backups in SQL Server: using SQL Server Management Studio. We review some of the backup metadata you can collect and also see how to compress and encrypt backups.
The first few videos in the series have all gone a bit longer than I expected, and that’s even with me pointedly ignoring most everything to do with tape drives.
Comments closedIn this video, I cover a class of algorithm that is neither particularly naive nor particularly Bayesian: Naive Bayes.
I am a bit tongue in cheek with that description, as technically I’ll give you that the class of algorithms is “naive.” But I do still have some fun with the name and then show how we can use Naive Bayes to build a quick-and-dirty model that’s at least somewhat effective.
Comments closedIn this video, I provide a primer on logistic regression, including a demystification of the name. Is it regression? Is it classification? Find out!
I have a lot of fun with this “Is logistic regression actually a regression technique, or is it secretly a classification technique?” I think this video is the single clearest explanation I’ve given on that question, which probably says something about my prior explanations.
Comments closedIn this video, I take a look at an alternative to bootstrap aggregation & random forest: boosting. We cover a brief history of boosting and see how it works in action with XGBoost and LightGBM.
This is probably the video with the single largest number of links in my show notes. It’s also one of the shortest in the series; it’s funny how things work out sometimes.
Comments closedIn this video, I cover a powerful ensemble method for classification: random forests. We get an idea of how this differs from CART, learn the best possible metaphor for random forests, and dig into random search for hyperparameter optimization.
Click through to see the video in all its glory.
Comments closedIn this video, we look at how to perform Infrastructure as Code in GitHub. We take a Bicep script and generate new Azure resources using it and GitHub Actions.
The video includes a very brief primer on Azure Resource Manager (ARM) and Bicep, and then gets into how you can use GitHub Actions to keep your Azure resources configured the way you expect.
