Data change capture based on SQL Server

Typical uses Typical uses of change capture are defined in Microsoft’s official documentation Change Data Capture uses SQL Server Agent to record inserts, updates, and deletes that occur in a table. A typical example of a data consumer targeted by this technology is extract, transform, and load (ETL) applications. ETL applications incrementally load changed data […]

torch_flops: FLOPs calculation library that accurately captures all operators in forward

Table of Contents Why you need the torch_flops library Introduction to torch_flops library Use and comparison of torch_flops Remaining limitations at last Why you need the torch_flops library When comparing the lightweight degree of neural network models, the FLOPs (Floating Point Operations. Reference link) indicator is usually used (but it should be noted that small […]

The SDK comes with test framework usage records (ADB&ADB SHELL, Monkey test, log capture, Automator tests, etc.)

Android SDK analysis Refer to this blog Android SDK analysis_android sdk res-CSDN blog ADB: Android Debug Bridge Understanding: As the name suggests, it serves as a “bridge” to connect computers and Android devices (or virtual machines), allowing users to directly transmit instructions/receive data to the device (virtual machine) through the computer without operating on the […]

[Signal] Signal processing {Timing of signal processing; kernel mode and user mode; principle of signal capture; signal processing function: signal, sigaction; reentrant function; volatile keyword; SIGCHLD signal}

1. Timing of signal processing 1.1 When does the operating system perform signal processing? First of all, we need to make it clear that the data structures for managing signals are all in the process PCB, and the process PCB belongs to the kernel data. Therefore, signal detection and processing must be performed in the […]

FFmpeg v4l2m2m capture and output

I found that the details of output and capture in encoder and decoder in FFmpeg v4l2m2m are a bit strange to understand. They are recorded as follows. encoder v4l2_encode_init external/ffmpeg/ffmpeg/libavcodec/v4l2_m2m_enc.c /* output context */ output->av_codec_id = AV_CODEC_ID_RAWVIDEO; output->av_pix_fmt = avctx->pix_fmt; /* capture context */ capture->av_codec_id = avctx->codec_id; capture->av_pix_fmt = AV_PIX_FMT_NONE; In the encoderencoder, capture corresponds […]
