Technical interviews can make or break your software career. 🎸 My new book, Rock Your Career: Surviving the Technical Interview, helps you beat ATS filters, handle recruiters, crush interviews, and negotiate smarter. Buy your copy: dotnettips.com/2026/06/01/roc… #Interviewing

Attention, non-software engineers: Anything you send from a computer or device—online or to the cloud—could potentially be accessed by developers (like me), administrators, or attackers. Think before you share. Protect your personal data. #ProtectYourData

Living near San Diego's stunning beaches has gifted me with incredible moments captured on camera! Check out these breathtaking photos from California, Mauritius, Mexico, and more. #BeachLife #Photography #TravelAdventures #SanDiego #Ocean #beaches davidmccarter.wordpress.com/2023/07/19/pho…

Dead project references? Orphaned project folders? Forgotten bin/obj files eating space? The free Spargine Dev Tool's audit command finds them fast and can export the report to Markdown. dotnettips.com/2023/02/24/spa… #dotnet #MVPBuzz

Some C# choices look like pure style until you crank up the amp and test them. Expanded methods and expression-bodied methods may play the same tune, but they do not always hit the stage the same way. #dotnet #csharp #performance #MVPBuzz dotnettips.com/2021/11/15/ref…

The software community didn’t die—it drifted. But we can bring it back. It's time to stop coding in isolation and rebuild the human side of tech. Connection, mentorship, craftsmanship—it all still matters. Let’s make it matter again. 💻❤️ #DevCommunity dotnettips.wordpress.com/2025/07/16/the…

“Whoever owns the most data will rule the world.” That was my tech prediction decades ago. Today, it’s reality. Here’s what that means for all of us—and how to fight back. #dotNetDave #GeekStory dotnettips.wordpress.com/2025/10/15/tec…

🚀 Want to speed up counting items in `IEnumerable<T>`? Benchmarking shows `Count()` is the clear winner—69x faster than `Span<T>.Length`! 🔥 Read more on optimizing .NET performance! dotnettips.wordpress.com/2025/04/16/opt… #Coding #Performance #MVPBuzz

Appending a single character in .NET? You might be doing it in a way that quietly kills performance every time you loop. 🧵⚡ Learn the right pattern with StringBuilder so your apps stay fast and allocation-friendly—especially at scale. 👇 dotnettips.wordpress.com/2024/04/17/str…

@csharpfritz You still code? 🤣

I’m spent my live stream yesterday writing code BY HAND for a few hours and it felt so good to write artisanal source code I’ve been vibe coding too much and I’m eager to do more development with less AI

If I hallucinated as much on the job as AI does, I’d be unemployed by lunch. AI, step away from the magic mushrooms and stick to the facts. 😣 @OpenAI @ChatGPTapp

@KarenPayneMVP That is exactly what Spargine is all about! dotnettips.com/spargine/

Professional developers should have predefined class libraries for both common and uncommon work. For instance, converting JSON to XML.

I’ve added new images to my Programming gallery—where code, creativity, and digital art collide. Take a look: mccarterphotography.smugmug.com/Graphic-Arts/P… #dotnet #programming

In C#, even small choices can change the way your code hits the stage. GetValueOrDefault() and the ?? operator may seem like the same riff, but there is more going on under the hood than most devs realize. No spoilers. #dotnet #csharp #performance #MVPBuzz dotnettips.com/2024/04/24/gen…

Want faster .NET apps and lower cloud costs? Explore practical ways to optimize file I/O, HTTP, TCP, UDP, sockets, and more—backed by benchmarks and real-world guidance. dotnettips.com/2026/07/12/opt… #dotnet #MVPBuzz

Your .NET app deserves better than scattered helpers and duct tape. Meet Spargine’s App class: runtime intel, diagnostics, zero nonsense. Turn your code up to 11 🎸 #dotnet #dotnet10 #MVPBuzz #Spargine dotnettips.wordpress.com/2024/10/29/boo…

HTTP/3 is the newest HTTP version in .NET—but is it always the fastest? Not so fast. I benchmarked HTTP/1.1, HTTP/2, and HTTP/3 across real scenarios, and the results might surprise you. Enable HTTP/3, but don’t ditch fallback. hubs.li/Q04pvkvj0 @RealDotNetDave

Most software engineering conferences skip speaker introductions, so years ago I started creating my own intro videos. Here’s my 2018 Star Wars–themed version. Attendees at .NET Day Switzerland will be the first to see the 2026 edition! 😆 youtu.be/Zi_H1quSW6Q #dotnetdaych

.NET engineers: Spargine Global Dev Tool is getting a Secrets feature! It checks developer certificates, warns before expiration, and flags sensitive files that could expose credentials. Download now—auto-update delivers it when released: dotnettips.com/2023/02/24/spa… #dotnet #MVPBuzz

Dear followers, I’m thrilled to receive my 20th Microsoft MVP award for Developer Technologies and .NET! Reaching 20 was a goal, but I still have plenty to share. Thank you to the MVP Program, Microsoft, and my amazing MVP friends. Let’s keep rocking your code! @MVPAward
