Shiny Apps and Fullscreen Behavior

Tim Brock gives us a demo:

Browsers have been implementing variations on a JavaScript fullscreen API for over a decade. Unfortunately, for much of that time the APIs varied across browsers. This made actually using it in production somewhat cumbersome.

Finally, with the release of Safari 16.4 in March of this year, the latest versions of all major desktop browsers now support a single, standardized interface. Legacy versions of Safari for desktop are still in use and there’s still no support at all for the Fullscreen API on iPhones; so while you can cover most users with the standardized API, it should still be for progressive enhancement and not as a fundamental requirement for operation of an application.

Listing Files by Date in R

Steven Sanderson shows off a built-in function:

In R, the function is a useful tool for retrieving file information, such as file attributes and metadata. It allows programmers to gather details about files, including their size, permissions, and timestamps. In this post, we will explore the function and demonstrate how it can be used to list files by date.

Read on for more information. This function is a lot more powerful than simply running ls or dir (without any flags) in a directory.

Computed Properties in Cosmos DB

Hasan Savran shows off a new feature in Cosmos DB:

A computed property is a virtual property that is not physically stored in a document. You can use data from other properties of a document to calculate a value for the computed property. This will help you to save CPU power since the database engine does not need to calculate the computed column value for each query request. In the Cloud CPU power means money! Computed Columns are like coupons you can use to save money.

Read on to learn more about how computed properties work, their limitations, and some examples of how to create and use them.

Code Signing on an Executable

Gianluca Sartori takes us through the process of signing our own executables:

Why does happen with some files and doesn’t happen with the Chrome installer or Acrobat reader? Because those setup kits are signed with a certificate from Google and Adobe, released by a certification authority that checks that Google is actually Google and not a disgruntled random guy pretending to be Google.

This means you can sign your code too, you just need to get a code signing certificate from a certification authority and they will be happy to give you one in exchange for money.

Click through for the step-by-step demonstration and a Powershell script to perform the signing.

Contrasting Lakehouse, Warehouse, and Datamart in Fabric & Power BI

Reza Rad disambiguates three terms:

Three types of objects in the Microsoft Fabric have similarities in what they can do for an analytics system. These three are; Lakehouse, Data Warehouse, and Power BI Datamart. All three objects provide storage for the data, which can be loaded into them using an ETL process and read using something like a Power BI report. In this article and video, I’ll explain the actual differences and how to choose the best option for your implementation and architecture.

Reza does a good job explaining when each of the three fit in and even has a nice chart to work out which one you might want to use.

Debunking Security Myths with SQL Server

Eitan Blumin has some myths for us:

Many organizations assume that their SQL Server is secure because it is behind a firewall. However, firewalls only block traffic to specified ports and protocols, and they do not protect against attacks that come through allowed traffic. Therefore, it’s important to secure SQL Server at a more granular level.

Furthermore, even if your SQL Server is not connected to the internet, it can still be hacked through internal attacks or by using compromised devices that connect to your network… If at least one privileged user can connect to the SQL Server, that means a malicious attacker potentially could do the same.

My one quibble is that number 5 isn’t a myth. I accept the importance of performing auditing, and people I know who have insane transactional throughput requirements still perform auditing, but there certainly is a performance effect. Otherwise, definitely worth the read.

SSIS Package Migration with dtutil

John McCormack does some spring cleaning:

SQL Server Integration Services (SSIS) is a powerful tool, but migrating packages across SQL Servers can be a slow and thankless task if you don’t use automation. The single best way to do this is by using DTUTIL, a command-line utility provided directly by Microsoft. When it comes to moving 1000s of packages, I would only use DTUTIL because it can achieve in minutes what it would takes days to achieve using point and click.

Read on to see how you can move these packages between instances, as well as downloading packages as a backup.
