Performance is everything. But correctness comes first.
There are many tutorials on using AI for coding, but far fewer on using AI for log analytics. We are living in exciting times as AI improves every day. If you spend most of your time troubleshooting business applications through log files, you might assume AI cannot help much yet. In most environments, scripts collect [ ]
640KB 100% are enough for everyone. I am talking about the Task Manager % CPU Utilization Graph and why it s 100% Utilization in the overall CPU % Utilization view is sometimes wrong, often misleading, and nearly aways useless for performance troubleshooting, although working correctly according to the specs. Update2 The fixed Task Manager has arrived [ ]
One of the harder lesson during development is how to deal with leaks. Most of the time you are leaking memory but sometimes also OS resources like Handles. These are more difficult to detect because the application does not use excessive amounts of memory when leaking OS resources. Leaks are not just wasteful; they can [ ]
What are hybrid CPUs? Hybrid CPUs are CPUs which have fast, but power hungry cores and slower but less energy consuming cores integrated into a CPU. All consumer grade desktop CPUs from Intel since Alder Lake (CPU number 12xxx or greater which was released in 2022) are hybrid CPUs. If you have recently bought an [ ]
Starting with Windows 10 KB 5025221 I had issues in Outlook to attach files to mails. Drag and Drop did become unreliable and would sometimes silently do nothing. When I tried the Attach File dialog it would most of the time work, but sometimes fail with: Update 2 The issue is fixed with June 2023 [ ]
Sometimes I get ETW traces which cannot be loaded by WPA. Initially I found these on Windows Server 2022 on a VMWare machine. I suspected some issue how VMWare virtualizes things on newer OSes but I did get this error also on my new non virtual Windows 11 box. After asking around it turned out [ ]
From a performance point of view Antivirus scanners are the worst things that have happened to computers during the last ca. 5 years. Sometimes it is hard to differentiate the CPU activity of an AV scanner from a bitcoin miner. Both are eating your CPU to give you either virtual security or virtual money. Whenever [ ]
The last test is from 2019 which is still accurate but the world is changing and we have arrived at .NET 7.0 which is reason enough to spin up my test suite again and measure from .NET 4.8, 3.1, 5.0, 6.0 up to 7.0. The old articles are still relevant despite their age. The following [ ]
Networking is hard and many things can go wrong. I have bought an Oculus Quest VR headset for my daughter. Soon I have found it frustrating to connect it via an USB cable to my PC. To get rid of the cable I have bought a cheap TP-Link Archer C5 AC1200 router which I connect [ ]
There are many extreme software development strategies out there. PDD can mean Panic Driven, or Performance Driven Development. The first one should be avoided, the second is a MSR paper dealing with performance modelling techniques. Everyone writes tests for their software because they have proven to be useful, but why are so few people profiling [ ]
