This article mainly explains "how to learn HelloGitHub". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to learn HelloGitHub.

C project

1. Acwj: a practical tutorial that teaches you how to write a C language compiler. The tutorial focuses on the actual combat step by step, and teaches you step by step how to write a C language compiler in C language that can compile yourself (bootstrap) and run on real hardware.

2. Zstd: the implementation of fast and lossless data compression algorithm Zstandard. The compression ratio of Zstd is close to that of lzma, lzham, and ppmx, and has better performance than lza or bzip2. In the case of similar compression ratio, its decompression speed is faster than other algorithms. Many well-known projects and games have this algorithm, sample code:

Static void compress_orDie (const char* fname, const char* oname) {size_t fSize; void* const fBuff = mallocAndLoadFile_orDie (fname, & fSize); size_t const cBuffSize = ZSTD_compressBound (fSize); void* const cBuff = malloc_orDie (cBuffSize); / * Compress. * If you are doing many compressions, you may want to reuse the context. * See the multiple_simple_compression.c example. * / size_t const cSize = ZSTD_compress (cBuff, cBuffSize, fBuff, fSize, 1); CHECK_ZSTD (cSize); saveFile_orDie (oname, cBuff, cSize); / * success * / printf ("% 25s:% 6U->% 7u -% s\ n", fname, (unsigned) fSize, (unsigned) cSize, oname); free (fBuff); free (cBuff);}

C # project

3. Ravendb: a fast and reliable open source NoSQL database

4. Files: a brand new file manager. Using the latest API implementation of Fluent Design and Windows platform, simple but not simple

Go project

5. Jql: a JSON data query tool written in Go. The tool is easy to install, the syntax is simple and easy to use, and there are many practical sample codes, such as:

# query the names of all countries in the test.json file cat test.json | jql'(elem "countries" (elem (keys) (elem "name")'["Poland", "United States", "Germany"]

6. Chanify: a service that pushes messages to iOS devices based on Go. After installing the matching iOS application on the phone, and then deploying the service in the way of Docker, you can push the specified message to APP through a command, isn't it very convenient?

# send text message $curl-form-string "text=hello"http://:/v1/sender/"# send text file $cat message.txt | curl-H" Content-Type: text/plain "- data-binary @ -" http://:/v1/sender/"

7. Algorithm-pattern:LeetCode exercise collection items. The project starts with an introduction to the Go language, and summarizes a set of exercise templates and problem solving routines. The sample code is Go.

8. Image processing library of imaging:Go language. Support: resize, rotate, cut, brightness adjustment and other functions, sample code:

/ / adjust dstImage128: = imaging.Resize (srcImage, 128,128, imaging.Lanczos) / / sharpen dstImage: = imaging.Sharpen (srcImage, 0.5)

9. 2D game engine library of ebiten:Go language. Through it, you can easily create 2D games that support multiple platforms in Go language, and the project also contains a lot of sample code to help you get started quickly.

Java project

10. Flink-recommandSystem-demo: a real-time commodity recommendation system based on Flink. Through this project, you can understand and learn the design and process of the recommendation system. The system processes logs and statistics of commodity popularity through Flink, and puts the processed data into the Redis cache. Then put the portrait tags and real-time records into HBase. When the user requests a recommendation, the product popularity list is generated according to the user's profile, and the final product recommendation list is returned by combining the two recommendation modules of collaborative filtering and tagging.

11. OpenRefine: a desktop tool for cleaning up data. Analyze and organize data in a visual way, and support Windows, Linux and Mac operating systems. With query, filtering, de-duplication, analysis and other functions, you can turn cluttered data into a "clean" spreadsheet, and export the results to files in various formats. Friends who don't know how to program and SQL can easily analyze huge amounts of data.
