Do not precompile regular expressions frequently
Background In frequent call scenarios, such as within method bodies or loop statements, newly defined Pattern will cause repeated precompilation of regular expressions, reducing program execution efficiency. In addition, some APIs in the JDK whose input parameters are in regular expression format, such as String.replaceAll, String.split, etc., also need to pay attention to performance issues. […]
Use of MMDeploy precompiled package under Windows system
Usage of MMDeploy precompiled package under Windows system The installation/usage difficulty of MMDeploy has been greatly reduced after entering the v1 version. Here we take the deployment of the Faster R-CNN model of the MMDetection project as an example. The PyTorch model is converted to ONNX and then to the Engine model, and is deployed […]
Ubuntu20.04 installs carla0.9.13 precompiled version and carla ros bridge
Because when using Anaconda’s python3.7 environment before, whether it is carla0.9.11 or carla0.9.13, launching the following ros bridge launch will cause carla to freeze, and no relevant solution has been found on the Internet.

C# SQLite version selection: Precompiled Binaries and Precompiled Statically-Linked Binaries, with bundle and without bundle
When writing Winform application in C#, we need to use SQLite database. However, when we download the SQLite binaries, we find two different binary options: Precompiled Binaries for 64-bit Windows (.NET Framework 4.6) and Precompiled Statically-Linked Binaries for 64-bit Windows (.NET Framework 4.6). So, which should we choose? What’s the difference? First, let’s understand the […]
