A Fine Slice Of SQL Server
I found a solution to an annoying problem:
After updating to the new Microsoft Teams, I could see my camera in the preview screen, but when I was in a meeting, I’d only see a black rectangle as myself. Other people mentioned that they could see me, though sometimes my video would drop off. Also, I was unable to see anybody else’s camera feed, nor could I see when people shared their screens.
Read on for the cause and solution that worked for me.

Ah, data! The lifeblood of many an analysis, but sometimes it can feel like you’re lost in a tangled jungle. Thankfully, R offers powerful tools to navigate this data wilderness, and filtering is one of the most essential skills in your arsenal. Today, we’ll explore how to filter both data.tables and data.frames, making your data exploration a breeze!

Comments closedSebastian Sauer shows off some code. There’s pretty much nothing to excerpt here, as it’s all code and images, so the gist of what Sebastian shows off is how to use the vjust parameter on ggplot2 labels to force where those labels show up.
Marco Russo and Alberto Ferrari have a public service announcement:
USERELATIONSHIP is a very common and helpful function, used whenever there are multiple relationships between tables and developers need to decide which relationship to use. However, in some scenarios, this common function raises an annoying error:
The UseRelationship() and CrossFilter() functions may not be used when querying ‘Sales’ because it is constrained by row-level security.
As with all the error messages, this requires some understanding and further explanation. Moreover, a workaround is straightforward to find. However, the workaround has some subtle restrictions that need to be well understood.

Comments closedJohn Miner returns to the old ways:
What is a metadata driven pipeline? Wikipedia defines metadata as “data that provides information about other data”. As a developer, we can create a non parameterized pipeline and/or notebook to solve a business problem. However, if we have to solve the same problem a hundred times, the amount of code can get unwieldly. A better way to solve this problem is to store metadata in the delta lake. This data will drive how the Azure Data Factory and Spark Notebooks execute.

Comments closedAndy Brownsword submits a series of requests through a proxy:
When executing packages for SSIS the default option would be to use the SQL Server Agent service account. We might not want to share an account between our services and Integration Services packages due to security risks.
Let’s take a common example: Suppose we have a package which reads from a file share. If permissions aren’t set up correctly this can fail. Even if access is corrected, the service account can cache that failure. The only way to resolve may be to restart the service. This isn’t something we’d want to be doing on production systems.

Comments closedSemab Tariq explains index options for Postgres’s vector database:
This blog is part of our pgvector blog series. If you haven’t checked out the first blog, I recommend going through it first, where I dive into important concepts of pgvector and AI applications in detail. I provided a real-world example illustrating how you can perform searches based on the meaning of words rather than the words themselves. You can find it on the link here
In this blog, We will explore additional details about the indexes supported in pgvector. We will discuss how indexes are built in the backend, and the various parameters associated with these indexes, and guide you on selecting the most suitable index based on your requirements. Finally, we will assess which index offers the best recall rate for our search query across our dataset of one million records sourced from Wikipedia. Let’s dive into that
