Network programming–realize echo server in pure overlapping IO mode
Write in front The overlapped IO model only introduces the Sender and receiver that perform overlapped IO, but the echo server has not been implemented using this model. Therefore, this article will implement an echo server based on the overlapped IO model on this basis. ioctlsocket The ioctlsocket function is used to create a socket […]
Network programming–overlapping IO model
Write in front The asynchronous notification IO model introduced in the article Asynchronous notification IO model belongs to the notification IO model, and the IO multiplexing described in the similar select implementation of IO multiplexing also belongs to the communication IO model. What is the notification IO model, that is, the IO is completed to […]

Algorithm Greedy 5 || 435. Non-overlapping intervals 763. Divide letter intervals 56. Merge intervals 738. Monotonically increasing numbers 968. Monitor binary trees
435. No overlapping interval It is very similar to 452. Exploding balloons with the least number of arrows. This question can be sorted on the left or on the right, and the ultimate goal is to make the intervals overlap as much as possible. 1. Sort by right, the right border of the first element […]
From the perspective of source code, why does Fragment overlap occur?
The version of the support package analyzed in this article is 23.3.0, and the Fragment overlap bug mentioned in the official article has been fixed on 24.0.0 and above. In the process of using Fragment, we sometimes find that the Fragment that has been performing normally suddenly overlaps! Under what circumstances will Fragment overlap occur? […]
GPU Programming CUDA C++ Using Multiple Non-Default CUDA Streams Concurrently Overlapping Kernel Execution and Data Transfer
Explanation of abbreviations: H: Host host D: Device device (GPU) K: Kernel kernel function H2D: Host copies data to GPU KER: kernel function execution D2H: GPU copies data to host Theoretical speedup: Using a default CUDA stream: (time is: 1) Stream 0: H2D —> KER —> D2H Concurrent overlap using four non-default CUDA streams: (Time […]
GPU programming CUDA C++ uses non-default CUDA streams to overlap multiple kernel functions to execute concurrently in the GPU
Kernel function external parallelism (can be divided into 5 categories): 1. Parallelism between kernel function calculation and data transmission 2. Parallelism between host computing and data transfer 3. Parallelism between different data transfers 4. Parallelism between kernel function computing and host computing 5. Parallelism between different kernel functions The following code example is the fifth […]
Use Jetpack Compose Modifier to achieve profile picture overlapping effect
Using Jetpack Compose Modifier to achieve profile picture overlapping effect First come 2 pictures of the effect you want to achieve: I want to display profile pictures in an overlapping manner. It’s not a recent design trend, but it’s still classy in 2023. Main attributes: light blue, image size with margins pink, negative spacing between […]
