Deadlocks can feel like a mystery, but they don’t have to be! In today’s episode, we’ll explore how to simulate and capture deadlocks in SQL Server using the powerful SQL Server Profiler.What Are Deadlocks?Deadlocks occur when two or more processes are waiting for resources held by each other, creating a circular wait. SQL Server resolves this by picking a “victim” process to terminate so the other transactions can continue.Capturing Deadlocks in SQL ServerTo analyze deadlocks effectively, we need to enable the right tools:Enable Trace FlagsSQL Server logs deadlock details in the error log when you enable trace flags 1204 and…
This article will teach you, how to leverage SBOM support in Spring Boot to implement security checks for your apps. A Software Bill of Materials (SBOM) lists all your app codebase’s open-source and third-party components. As a result, it allows us to perform vulnerability scanning, license checks, and risk analysis. Spring Boot 3.3 introduces built-in support for generating SBOMs during app build and exposing them through the actuator endpoint. In this article, we will analyze the app based on the latest version of Spring Boot and another one using the outdated version of the libraries. You will see how to…

From now until Christmas, I will be giving away hundreds more. You can start learning Python for free using my books or courses. All you have to do is follow me on one of these platforms and watch out for my post that describes how to get a free book or course:
I had to demo the Flyway Autopilot system recently and created a GitHub Actions runner as a part of that. This post documents how this went.First, if you go to the settings in a repo and click the Actions area, you see a Runners item. Click that. Notice I have no runners.In the upper right corner, I can click a button to create one.This gives me the instructions to get a new one. Note, these are PowerShell commands, and the first command doesn’t quite work right. Still, this is what I need.I opened a CMD window and stared running these.…
Here is the top 100 PHP functions : it is the list of the most often used PHP native functions. The functions are named, and ranked from 1 to 100. The other 4500 functions are not ranked here. The frequency column represents how often this function is used across PHP code repositories : the reference corpus is a list of 2500 PHP Open Source projects (top 1000 composer, github/gitlab/gitee public repo, downloaded archives…). They were audited with Exakat static analysis engine, version 2.4.7. The average is the number of time the function is called within one project. For example, 4…
Sorting large datasets in SQL Server can significantly impact performance, especially when it leads to tempdb spills. This post explores why this happens, how to identify it, and some quick tips to optimize your queries.What Causes TempDB Spills?Tempdb spills occur when SQL Server does not allocate enough memory for operations like sorting. The spill results in SQL Server writing intermediate data to tempdb, which introduces additional I/O overhead. Here’s an example scenario:The sort operator processes over 121,317 rows, but SQL Server grants only 6,000 KB of memory.Insufficient memory causes the operation to spill, leading to:460 pages written to tempdb.Approximately 10…
Have you ever tried examining the size of an entire Angular project and comparing it to the size of the code compiled by Angular (its build output in the dist folder)?The difference is almost hard to believe. Typically, the entire project folder of an Angular app is well above 600MB, which includes a lot of things, including your code, all your dependencies, but also the Angular CLI, the TypeScript compiler, and more:After running ng build, your dist folder is much smaller than 600MB, usually just a few KB or MB, depending on the size of your application.This is because of…
