Although GPT-4 is very expensive, but it’s not impossible to use it for free and unlimitedly. In this article, I will introduce 4 ways to achieve this goal. Before starting, let me first introduce three questions that can be used to distinguish between GPT-3.5 and GPT-4. You can use these questions to test whether the model is GPT-4 or not. https://www.sainnhe.dev/post/doh-vs-dot-benchmark/ Tue, 17 Jan 2023 14:51:51 +0800 https://www.sainnhe.dev/post/doh-vs-dot-benchmark/ Background What is a DNS server? What is an IP address? IP address is a string consist of numbers and dots, for example 142.250.69.196. It is the identification of a computer in the network, we can use it to identify a computer in the network and establish a link with it. What is a domain name? Domain name is a string consist of English characters and dots, for example www.google.com. It is the identification of a computer (or a service) in the network, we can use it to identify a computer (or a service) in the network and establish a link with it. https://www.sainnhe.dev/post/kmp/ Thu, 01 Dec 2022 10:02:15 +0800 https://www.sainnhe.dev/post/kmp/ Leetcode 28.

All of my color schemes share a very similar code base, so I’m going to take one of these color schemes gruvbox-material for example in this post. Code Structure /.githooks/pre-commit: Pre-commit hook. /autoload/gruvbox_material.vim: Contains helper functions and color palette. /autoload/airline/themes/gruvbox_material.vim: Airline theme. /autoload/lightline/colorscheme/gruvbox_material.vim: Lightline theme. /colors/gruvbox-material.vim: The color scheme file. /doc/gruvbox-material.txt: The help doc. /lua/lualine/themes/gruvbox-material. https://www.sainnhe.dev/post/enable-flash-player-in-2022/ Sat, 27 Aug 2022 09:56:20 +0800 https://www.sainnhe.dev/post/enable-flash-player-in-2022/ 介绍 Adobe 在 2020 年彻底终止了对 Flash Player 的支持, 随后各大主流浏览器（Chrome, Firefox, Safari 等）也开始纷纷移除 Flash Player 的相关代码。目前在这些浏览器的最新版本中，即 https://www.sainnhe.dev/post/deploy-gitea-and-drone-on-raspberry-pi-4b/ Sat, 16 Jul 2022 19:24:18 +0800 https://www.sainnhe.dev/post/deploy-gitea-and-drone-on-raspberry-pi-4b/ 介绍 之前入手了一块树莓派 4B, 但一直放在角落里吃灰。最近看到 GitHub Copilot 开始收费，感觉自己就像在给巨硬打白工，于是心血来潮想要在树莓派上搭建一个 Gitea 和 Drone 服 https://www.sainnhe.dev/post/recommendation-of-macos-apps/ Thu, 09 Jun 2022 19:16:48 +0800 https://www.sainnhe.dev/post/recommendation-of-macos-apps/ In this post, I’m going to introduce some macOS apps that I’m using. All of them are free of charge. FOSSs (Free and Open Source Softwares) are marked by ⭐. MacPorts ⭐ This is a package manager, something like a third-party App Store, but in command line. Many people may prefer homebrew, but I would say even if MacPorts is not to your taste, don’t use homebrew. IT IS UNSAFE! https://www.sainnhe.dev/post/patch-fonts-with-cursive-italic-styles/ Thu, 21 Apr 2022 16:15:27 +0800 https://www.sainnhe.dev/post/patch-fonts-with-cursive-italic-styles/ Update at 2023-11-23 In order to avoid potential legal issues, I decided not to distribute these font files on the public website. If you want to obtain these fonts, register an account on my gitea instance and send me an email, I’ll invite you to a private repository which contains all these font files and the source code. TL;DR Go ahead to https://git.sainnhe.dev/sainnhe/icursive-nerd-font, download the fonts you like. git.sainnhe.dev is hosted on Raspberry Pi 4B, it may not be available at all times. https://www.sainnhe.dev/post/dockerize-your-dotfiles/ Sun, 20 Feb 2022 16:07:09 +0800 https://www.sainnhe.dev/post/dockerize-your-dotfiles/ Introduction If you are like me and prefer to develop in a complete TUI environment with neovim, you may encounter a situation where you need to reconfigure your development environment every time you face a new OS. You may need to install packages, copy dotfiles and do some other stuffs over and over again, which is really annoying. Docker, which can provide OS-level virtualization, may be able to provide a solution to this problem. https://www.sainnhe.dev/post/dont-use-homebrew/ Sat, 01 Jan 2022 10:29:05 +0800 https://www.sainnhe.dev/post/dont-use-homebrew/ What? Yes exactly, you should never use it. I know this might shock you, but please let me explain. There are two very serious design flaws in homebrew, which may put your mac in danger. The directory permission Homebrew doesn’t need sudo to perform actions, which has been regarded as a big advantage over other package managers. Yes, it’s more convenient, however the way homebrew implements this feature is simply to change the ownership of the directory of $(brew --prefix) to the user who installed homebrew. https://www.sainnhe.dev/post/introduce-whoogle-search-engine/ Fri, 10 Dec 2021 19:56:35 +0800 https://www.sainnhe.dev/post/introduce-whoogle-search-engine/ 中文搜索引擎 现在百度的搜索结果充斥着百度文库、百度知道、百家号、CSDN 等垃圾，包括我在内的很多人都在尝试找一个中文搜索引擎的替代品。 360 和搜 https://www.sainnhe.dev/post/surface-repair/ Sun, 26 Sep 2021 16:38:47 +0800 https://www.sainnhe.dev/post/surface-repair/ 损坏原因 Surface 系列的笔记本由于其内部构造太过精密，很多电脑维修店都不敢拆。我的 SB2 用了一年多之后就明显感觉散热有点问题了，初步判断是因为长时间没有 https://www.sainnhe.dev/post/create-personal-arch-linux-package-repository/ Sun, 21 Feb 2021 16:10:05 +0800 https://www.sainnhe.dev/post/create-personal-arch-linux-package-repository/ About For whatever reasons, you may want to create your own package repository, like this: repo.sainnhe.dev In this article, I’m going to record my steps to create my own arch linux package repository, via github pages, no need to maintain your server. Build signed packages Create your gpg key When you installed a package from AUR, you generally cloned a repo that contains a PKGBUILD file, then you executed makepkg to build this package. https://www.sainnhe.dev/post/void-wsl2/ Sun, 23 Aug 2020 10:51:21 +0800 https://www.sainnhe.dev/post/void-wsl2/ About Windows 10 version 1909 is finally available for my surface device, I’ve waited for it for several months since there is a very important new feature: WSL2 IMO, WSL1 is not suitable for daily development because the performance is TOO BAD.
