The CSS project

Tailwindcss: a CSS framework based on the idea of utility-first, smaller and more flexible than components. The idea is simply to use classes to ensure flexibility and ease of customizing components, rather than personalization on top of them. The framework has received mixed reviews online, but I thought it was good and wanted to learn

Go project

7. Inlets: A free Intranet penetration service based on Go, which exposes local services to the public network. If you find the Intranet penetration tool difficult to use or expensive, you can try this project and use the instructions

It does not need to be installed, only need to download the corresponding system compression package decompression can be directly run and use. It can be used to set up a private Web disk, and supports multiple operating modes including the command line, Web, and desktop programs and file synchronization between the Intranet and Internet. Another alternative to paid web disk, if you consider the high bandwidth costs. Syncthing can be used as an open source solution for sharing files with phones, TVS, and computers over the LOCAL area network

Lazykube: a command line tool that supports mouse operation and management of K8s. Contrast k9S command line tools, can not remember so many shortcut keys, direct mouse operation. Solve the scenario where the company does not use Rancher and Dashboard to manage K8s and can only be accessed through the Fortress. All you need to use this tool is a terminal and a mouse, although you still need a keyboard 😂 for search

  ctx := svc.NewServiceContext(c)
  server := rest.MustNewServer(c.RestConf)
  defer server.Stop()

  handler.RegisterHandlers(server, ctx)

  server.Start()
}

17. Piano: A piano app based on Omi and Omi Snippets. You don’t need any knowledge of music theory, just use the keyboard to play simple and familiar music, thanks for the music and programming company of this project! Music has never failed anyone. As Leehom Wang sings, “If the world is too dangerous, only music is safe. Take me to my dreams and make the lyrics come true!” The above paragraph is a recommendation written by the author. I wanted to praise the project from the perspective of the project, but I gave up. Although the piano project I recommended before is better than this one, I prefer this one. Because I feel a lot of respect and “love” from his project, salute every struggling “coder”, HG love you. Sample code for online attempts:

playSong(song) {
  this.setSong([...song])
  let offset = 0
  let time = 0
  let playSong = async() = > {// The right-hand side breaks the recursion from the outside
    if (offset < song.length && this.store.data.song.length > 0) {
      switch (typeof song[offset]) {
        ++12345--6. Simple melodies
        case 'string':
          let letters = song[offset].match(/[0-9]/g)
          switch (letters.length) {
            case 1:
              time = this.handleString(song, offset)
              break
            default:
              time = this.handleStrings(song, offset)
              break
          }
          break
        // Simple notation 1 plays according to CDEFGAB, complex melodic situations, such as chords
        case 'object':
          console.log(song[offset]['note'])
          time = song[offset]['time'];
          this.playNote(song[offset]['note'])
          break;
        case 'number':
          / / rests.
          switch (song[offset]) {
            case 0:
              time = 1000
              break
          }
          break
      }
      await new Promise((resolve) = > {
        let timer = setTimeout(() = > {
          clearInterval(timer)
          resolve()
        }, time)
      })
      offset++
      // Custom event, with the bottom note automatically beat in combination
      this.add()
      playSong()
    } else {
      // Pause the playback
      clearTimeout(this.timer)
      this.store.data.song = []
      this.store.data.count = 0
      return
    }
  }
  playSong()
}

Python-cheatsheet: A comprehensive and useful Python memo. For example, I can’t remember how to write regs in Python, I can’t remember library names and basic usage for a progress bar, and I can’t remember method parameters for processing data in PANDAS. I found this project just when I thought I needed to “go back to the drawing board,” and I found snippets of code that worked with all of its problems. I’m the happy Pythoneer again.

# $ pip3 install tqdm
>>> from tqdm import tqdm
>>> from time import sleep
>>> for el in tqdm([1.2.3], desc='Processing') :.    sleep(1)
Processing: 100% | █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ |3/3 [00: 03 <00:00.1.00s/it]

Swift project

Eul: a minimalist free macOS status monitoring tool. I’m using it. I highly recommend it

other

Winapps: a program that lets you use Windows Office software on Linux (Ubuntu/Fedora) systems. Supports Microsoft Excel, Word, PowerPoint, and Adobe Photoshop

26. Front-end-interview-notebook: A non-patchwork, good front-end Interview review note. To ask questions, and give the author’s answer, the content covers: HTML, CSS, JS, algorithms, computer networks and so on. The author got a lot of offers from big factories, and then summarized these things and sent them to the front-end partners who were preparing for the interview and changing jobs

27. Pi-hole: A free open source DNS Sinkhole project with easy deployment. It doesn’t matter, I don’t know what DNS Sinkhole is, but I know it can be used to implement the router layer to block advertising function. You need to install this project on raspberry PI first, and then with a router that supports custom DNS, you can implement automatic blocking of all devices under the network. The detailed steps

CopyTranslator: a cross-word translation tool for web pages and PDFS. With it can solve the problem of garbled, newline and inaccurate translation when reading PDF files to translate large sections of content

Styleguide: Google’s code styleguide. Every large project has its own code style, which is easier to understand when the code has a uniform style. This project is Google project code style description, including: C++, C#, Swift, Python, Java and other languages

30. Upptime: a free open source website uptime monitoring service. It doesn’t cost anything because it’s entirely based on GitHub’s free services, such as using GitHub actions to visit a target site every 5 minutes to get the latest status. Then record and report exceptions through GitHub Issues, and finally display the running status of the website visually on GitHub Pages. It is very “green pollution-free”, I particularly like

Machine learning

Examples: A collection of PyTorch examples for vision, text, etc. Including: Image classification using Convnets (MNIST), generative adversarial network (DCGAN), etc

EasyOCR: Ready-to-use Python OCR library that supports multiple languages, including Chinese, Japanese, Korean, etc. Sample code:
