这篇博文是（2011年）从新浪博客迁过来的。新浪的编辑还有点人味，这篇没有彻底给删掉，给搁回收站了。转到这儿，看看点点是不是开明一点。 这本书是阮一峰在他的2010年终总结博客里推荐的。 读这本书之前，我对吴法宪的了解仅限于以往看到听到的一些官方说法，四人帮的帮凶什么的。对这本书一开始也没大重视，一个大老粗，文字能好到哪里去呢？不过既然阮一峰会推荐，这书肯定有可取之处。 本着看闲书的态度找到这本书的电子版，扔到kindle里，准备有一搭没一搭的看。 这书篇幅挺大，有八十余万字。一周前开了头，看了十来页，我就知道这本书我一定会全部读完了。 …more
本文最初发表在今天已经死掉的点点博客。 我的第一个移动读书设备是黑莓8310。在那小小的屏幕上我读完了厚厚的一本《代码大全》。 后来买了吹的牛哄哄的号称读PDF多好多好的歌美S6000。屁，操作之慢让我忍不住想起我那只扔在一边的N73手机，阅读时间短不说，电量指示还超不准。读着读着，不定啥时候突然就没电了。 扔一边了，真可惜了8个G的容量。 然后就买了kindle3。刷了多看系统，这次看PDF真的爽了。更爽的是待机时间，充一次电能看两个礼拜。老早就听说这玩意屏不结实，所以入手大半年来，一直小心着小心着，生怕它那脆弱的小屏坏掉。然而，前几天悲剧还是发生了：要和儿子出去玩，我把kindle装包里，包跨在我胳膊上。我为了帮他找鞋子就趴在地上往沙发底下瞧，鞋子是找到了，可起身才发现包在我膝盖底下。啊呀呀，叫也没用，kindle3屏幕果然坏掉。在等待换屏的日子里，顺理成章儿子的iPAD成了暂时的替代。 原来iPAD也是看书利器。虽然最初沉甸甸地，好象有点受不了。可连着带了几天之后发现竟然有些适应了。反应敏捷，操控一流，彩色，大屏，十几小时的阅读时间，除了一点点反光让人稍微不爽，在习惯了iPAD的重量之后，我竟然有些爱不释手了。 要不要就此让那个kindle3成为往事？嗯，这事儿我看行。 2011/06/20

When working with Postman to automate API testing, you might encounter scenarios where you want to conditionally skip the execution of subsequent requests in a collection. This can be useful if a certain condition isn't met in your API responses. Here's a guide on how to achieve this using Postman's scripting capabilities. Scenario Imagine you have a collection where the first request returns a response like this: { "content": "True", "statusCode": 200, "message": "Global value got from DbConfig!" } You want to skip all subsequent requests if the content field is "False". Step-by-Step Guide Set Up Your Collection: Ensure your collection is organized with the request you want to evaluate placed at the beginning. Write a Post-Request Script: In the test script section of the first request, you'll write a script to check the content field and decide whether to continue the collection run. // Parse the response let response = pm.response.json(); // Check the content value if...
一个朋友说 Gemini最近的进步已经挺大了，于是我就试验了一下。 我问Gemini：你能否用简洁的汉语详细解释一下import { ref, onMounted, watch } from 'vue'这一语句import的这三个对象？它们是什么，做什么用，好的实践是什么？ Gemini的回答令我非常满意，因此我把它发表在这里。它的回答是： 好的，我来详细解释一下这段代码中导入的三个对象： import { ref, onMounted, watch } from 'vue' 解释： import： 这是 JavaScript 中的导入语句，用于从其他模块（这里就是 Vue.js）中引入需要的功能。 想象一下，你在搭建积木，import 就相当于你从积木盒里拿出特定的积木块。 ref, onMounted, watch： 这些都是 Vue.js 提供的三个核心功能： ref： 作用： 创建一个响应式的引用。 比喻： 想象一个盒子，你把一个数据放进去，这个盒子就变成了一个 ref。当盒子里面的数据发生变化时，Vue 会自动追踪到，并触发相应的更新。 使用场景： 用于创建响应式的基本数据，比如一个计数器、一个输入框的值等。 onMounted： 作用： 在组件挂载到 DOM 后执行一次回调函数。 比喻： 就像一个新房子建好了，你就可以搬进去开始装修了。onMounted 就是在你搬进去之后执行的第一个动作，比如打开窗户通风。 使用场景： 用于执行一些初始化操作，比如获取数据、设置定时器等。 watch： 作用： 监听一个值的改变，并在值改变时执行回调函数。 比喻： 就像你设置了一个监控摄像头，一旦监控到有物体移动，就会触发报警。watch 就是这个监控摄像头，它会持续监控一个值，一旦值发生变化，就会执行你设定的操作。 使用场景： 用于实现一些复杂的逻辑，比如根据数据的变化动态更新视图、进行表单验证等。 总结： ref 用于创建响应式数据。 onMounted 用于在组件挂载后执行初始化操作。 watch 用于监听数据的变化并执行相应的操作。 好的实践： 合理使用 ref： 不要过度使用 ref，只对需要响应式的数据进行包裹。 在 onMounted 中进行异步操作： 将获取数据、设置定时器等异步操作放在 onMounted 中，确保组件已经挂载到 DOM 中。...

惠勒延迟选择实验（Wheeler's Delayed Choice Experiment）是一个量子力学的思想实验，旨在探讨测量对量子系统的影响，尤其是在我们“选择”测量的时刻与量子系统的历史之间的关系。这个实验的结果挑战了我们对因果关系和时间的传统理解，尤其是在量子层面上。 实验背景 首先，了解双缝实验（Double-Slit Experiment）是理解惠勒实验的基础。在经典的双缝实验中，单个粒子（如光子或电子）通过两个狭缝并在屏幕上形成干涉图样。这显示粒子似乎像波一样通过了两条路径。但如果我们在狭缝处放置探测器来测量粒子通过哪一个狭缝，干涉图样会消失，粒子表现得像个经典粒子，只通过了一条路径。 惠勒的延迟选择实验 惠勒延迟选择实验则在此基础上提出了一个令人困惑的思想实验：如果我们在粒子通过双缝后，甚至在它接近屏幕时才决定是否测量它通过哪条缝会怎样？ 实验的核心思想是： 光子或粒子先通过双缝，接着才进入实验者是否测量的选择区域。 如果我们选择不测量路径信息，光子将像波一样表现，形成干涉图样。 如果我们选择测量路径信息，光子则表现为粒子，干涉图样消失。 在延迟选择实验中，实验者是在粒子已经通过双缝后才决定是否测量路径信息。令人困惑的是，实验结果仍然符合经典双缝实验的规律：如果我们“延迟”选择测量路径，粒子依旧表现为粒子；如果我们不选择测量，粒子仍然表现为波。 困惑的源头：现在的选择影响过去？ 这个实验结果带来的困惑是：我们的“延迟选择”似乎影响了粒子过去的行为。也就是说，光子在通过双缝时“知道”我们未来会不会测量它的路径，从而决定以波的形式通过两个缝，还是以粒子的形式通过其中一个缝。 然而，这种解释仅仅是表面现象。量子力学的本质不是粒子“提前知道”了什么，而是测量本身在量子层面上扮演了一个创造性角色。也就是说，量子的状态并不是在我们测量之前就固定的，而是测量行为本身决定了量子状态的表现。 关键点 量子叠加态：在没有测量之前，粒子处于一种叠加态，既是波也是粒子，既通过了两条路径，也只通过了一条路径。测量行为使叠加态“坍缩”到一个确定的状态。 因果关系：在经典物理学中，因果关系是线性的，即因在前，果在后。但在量子力学中，因果关系不像我们习惯理解的那样简单，测量的时间顺序并不能简单地被理解为影响事件发生的唯一因素。...

The error occurs because AppBar expects a widget that implements the PreferredSizeWidget interface, but Consumer<NoteModel> does not directly implement this interface. To solve this, you need to return an AppBar from within the Consumer builder method. Here’s how you can do it: Scaffold( appBar: PreferredSize( preferredSize: Size.fromHeight(kToolbarHeight), child: Consumer<NoteModel>( builder: (context, noteModel, child) { return AppBar( title: Text( 'Your Title', style: TextStyle( color: noteModel.isPrivate ? Colors.red : Colors.green, ), ), ); }, ), ), body: // Your other widgets, ); In this approach, I wrapped the Consumer<NoteModel> inside a PreferredSize widget to ensure it adheres to the PreferredSizeWidget interface required by appBar. This should resolve the error while allowing you to update only the AppBar based on changes in your NoteModel. Glory to ChatGPT!

In C#, both FirstOrDefault and SingleOrDefault are LINQ methods that operate on collections, but they serve different purposes: FirstOrDefault Purpose: Returns the first element in a collection that satisfies a specified condition, or the default value for the type if no such element is found. Behavior: If the collection contains multiple elements that satisfy the condition, it returns the first one. If no elements satisfy the condition, it returns the default value (null for reference types, 0 for numeric types, etc.). Use Case: When you're interested in getting the first match or a default value if none exist, and you don't care if there are multiple matches. SingleOrDefault Purpose: Returns the single element in a collection that satisfies a specified condition, or the default value for the type if no such element is found. Behavior: If the collection contains exactly one element that satisfies the condition, it returns that element. If no elements satisfy the condition, it...

I found this brilliant answer at Stack overflow. It is way more clearer and useful than Microsoft's official one You can use inline modifiers as follows: // case insensitive match Regex MyRegex = new Regex(@"(?i)[a-z]+"); // case insensitive match or, inverse the meaning of the modifier by adding a minus-sign: // case sensitive match Regex MyRegex = new Regex(@"(?-i)[a-z]+"); // case sensitive match or, switch them on and off: // case sensitive, then case-insensitive match Regex MyRegex = new Regex(@"(?-i)[a-z]+(?i)[k-n]+"); Alternatively, you can use the mode-modifier span syntax using a colon : and a grouping parenthesis, which scopes the modifier to only that group: // case sensitive, then case-insensitive match Regex MyRegex = new Regex(@"(?-i:[a-z]+)(?i:[k-n]+)"); You can use multiple modifiers in one go like this (?is-m:text), or after another, if you find that clearer (?i)(?s)(?-m)text (I don't). When you use the on/off switching syntax, be aware that the modifier works till...

You probably know: git diff shows unstaged changes. git diff --cached shows staged changes. But how do you see all changes in one go? Just use: git diff HEAD Here's the breakdown: git diff compares the working directory to the staged index. If nothing is staged, it's the same as git diff HEAD. git diff --cached compares the staged index to HEAD. It's a shortcut for git diff --cached HEAD. git diff HEAD (or git diff <commit/branch/tag>) compares your current working directory with the specified commit.

The Dart ... spread operator is a powerful feature that allows you to insert multiple elements from a collection into another collection. This is particularly useful when building Flutter widget trees, as it can make your code more concise and readable. What is the Spread Operator ...? The ... operator is used to expand elements of a collection and add them to another collection. For example: List<int> list1 = [1, 2, 3]; List<int> list2 = [0, ...list1, 4]; print(list2); // Output: [0, 1, 2, 3, 4] Using the Spread Operator in Flutter Widgets In Flutter, you can use the ... operator to conditionally add multiple widgets to a widget list, making the code cleaner and more maintainable. Without the Spread Operator If you don't use the ... operator, you might end up writing repetitive conditional checks like this: AppBar( title: const Text('Note Details'), actions: [ if (widget.note.userId == UserSession().id) IconButton( icon: const Icon(Icons.edit), onPressed:...

In a recent project, I ran into an issue where I needed to refresh a page when the user navigated back to it. After searching on google and asking ChatGPT, I found this simple and clean solution. What is RouteObserver? RouteObserver is part of the Flutter framework that helps you track navigation events in your app. It allows you to listen to changes in the route stack, such as when a route is pushed or popped. This is incredibly useful for scenarios where you need to refresh or update your UI based on navigation. Setting Up RouteObserver First, I created a UserSession class to hold a singleton instance of RouteObserver. Here’s the gist: // user_session.dart import 'package:flutter/material.dart'; class UserSession { static final UserSession _instance = UserSession._internal(); static final routeObserver = RouteObserver<ModalRoute>(); UserSession._internal(); } By doing this, I could easily access routeObserver from anywhere in my app. My UserSession also holds other user...
Managing time zones can be tricky, especially in regions that observe daylight saving time (DST). Using the right time zone identifiers can simplify your work by automatically adjusting for these changes. Here’s a quick guide to best practices for handling time zones, using examples from New Zealand and Australia. The Problem with Fixed Time Zones The Problem with Fixed Time Zones Using fixed time zones like NZST (New Zealand Standard Time) typically doesn't account for daylight saving changes, potentially leading to incorrect time calculations during daylight saving periods. However, certain platforms, such as .NET, which handles these transitions internally, giving the correct local time. This behavior might not be consistent across different platforms and systems. The Best Practice Solution The best practice is to use time zone identifiers that handle both standard and daylight saving times automatically. These identifiers switch between standard time and daylight saving time...
In the HappyNotes project, I encountered a perplexing issue with the NoteModel not updating as expected across flutter widgets. Despite initializing NoteModel with initial values and using ChangeNotifierProvider, the state changes weren’t reflecting in the model when I try to collect data back. This article outlines the troubleshooting process and solution, which can be a valuable guide for other developers facing similar challenges. Background In HappyNotes project, the NewNote widget is where users could create notes. Each note had properties like isPrivate and isMarkdown, managed through a NoteModel using ChangeNotifier. Here’s a simplified version of the relevant parts of my setup: class NoteModel extends ChangeNotifier { bool isPrivate; bool isMarkdown; NoteModel({this.isPrivate = true, this.isMarkdown = false}); set isPrivate(bool value) { _isPrivate = value; notifyListeners(); } set isMarkdown(bool value) { _isMarkdown = value; notifyListeners(); } } The NewNote widget...
Provider is a powerful state management solution in Flutter that allows for efficient and organized management of app state. In this guide, we'll explore some best practices for using Provider to keep your Flutter apps clean and maintainable. Why Use Provider? Provider offers a simple, scalable way to handle state management in Flutter apps. It's ideal for sharing and managing state across widgets, especially in large applications where state needs to be accessed from various parts of the app. 1. Utilize MultiProvider for Multiple Models When your app requires multiple state models, initializing each one individually can become cumbersome. Instead, use MultiProvider to group your models together efficiently. This keeps your main function neat and ensures that all your models are readily available throughout the app. Example: import 'package:flutter/material.dart'; import 'package:provider/provider.dart'; import 'package:your_app/models/note_model.dart'; import...

In this tutorial, I'll walk you through setting up a simple API server using Express and express-jwt for JSON Web Token (JWT) authentication. By the end, you'll have a functional server that can issue JWTs and verify them for secure endpoints. Let's dive in! Step 1: Setup and Install Dependencies First, create a new project directory and initialize a Node.js project. Then, install the required packages: mkdir express-jwt-api cd express-jwt-api npm init -y npm install express express-jwt jsonwebtoken body-parser Step 2: Create the Basic Server Create a server.js file to set up your Express server: const express = require('express'); const bodyParser = require('body-parser'); const routes = require('./routes'); const app = express(); app.use(bodyParser.json()); app.use('/api', routes); const PORT = 3000; app.listen(PORT, () => console.log(`Server running on port ${PORT}`)); This code sets up an Express server and uses body-parser to parse JSON requests. Step 3: Define Routes Create...
Introduction When working with relational databases in .NET, one common requirement is to join related tables and map the results to objects. This can become cumbersome if done manually for each field. SqlSugar, a powerful ORM for .NET, simplifies this process by providing built-in methods for automatic mapping. This blog post will guide you through using SqlSugar’s Mapper feature to map related objects efficiently. Setting Up Your Entities Let’s start by defining two simple entities: Note and User. We want to map User information into each Note record based on a foreign key relationship. public class Note { [SugarColumn(IsPrimaryKey = true, IsIdentity = true)] public long Id { get; set; } public long UserId { get; set; } public string Content { get; set; } = string.Empty; [SugarColumn(IsIgnore = true)] public User? User { get; set; } // Navigation property for User } public class User { [SugarColumn(IsPrimaryKey = true, IsIdentity = true)] public long Id { get; set; } public string...
If you’ve worked with Flutter’s ListView, you might have encountered a scenario where you navigate between pages, and upon returning, the scroll position isn’t where you expected it to be. Recently, I faced a similar challenge with a note-taking app. Every time I moved between pages, I ended up at the bottom of the new page. Not the best user experience, right? The Problem In my note-taking app, I wanted the NoteList widget to always start at the top position whenever it’s built or updated. This way, users wouldn’t have to manually scroll up to see the latest notes. The challenge was to encapsulate the scroll behavior within the NoteList widget itself, without having to manage the scroll status from its parent widget. Here’s how we achieved that. The Initial Implementation Initially, NoteList was a simple StatelessWidget that displayed a list of notes grouped by their creation date. However, it didn’t retain or reset the scroll position upon navigation or page refreshes, which led...
pushReplacement Imagine you're replacing an old road sign with a new one. The old one is gone, and there's no way to know it was ever there. That's what pushReplacement does in Flutter. Usage: Navigator.pushReplacement(context, newRoute) What It Does: Replaces the current route with a new route. The current route is removed from the stack, making way for the new route. The removed route is completely gone—pressing the back button won’t bring it back. When to Use It: Ideal for scenarios like replacing a login screen with a home screen after a user logs in. You don’t want them to go back to the login screen, right? Code Example: Navigator.pushReplacement( context, MaterialPageRoute(builder: (context) => HomeScreen()), ); pushAndRemoveUntil Now, think of pushAndRemoveUntil as clearing a cluttered desk, keeping only the essentials. You decide which items stay and which go. This function allows more control over which routes to remove. Usage: Navigator.pushAndRemoveUntil(context,...

In the realm of modern web development, the HTTPS protocol stands as a cornerstone of security. While Let's Encrypt provides SSL certificates at no cost, their certificate chains don't always play well with older Android versions, such as Android 5. This guide delves into the art of generating Android 5-compatible certificates and automating their renewal. Step 1: Install Certbot and Nginx Before embarking on this quest, ensure that your Ubuntu host has Certbot and Nginx installed. sudo apt-get update sudo apt-get install certbot nginx Step 2: Download ISRG Root X1 Certificate From the Let's Encrypt website, procure the latest ISRG Root X1 certificate and store it in a designated directory. sudo wget -O /etc/letsencrypt/isrgrootx1.pem https://letsencrypt.org/certs/isrgrootx1.pem Step 3: Craft the Automation Script Forge a script named "update-certificates.sh" that automatically generates an Android 5-compatible certificate chain and reloads Nginx's configuration whenever Certbot...

我纵苦学不缀，所学之深度与广度亦极有限。而AI只要有电力算力供应，谈笑间，学尽人类数千年积累之学问。我甚悲，极其羡慕AI之能力。然悲之余，何不问询一下AI？读完它们的回答，我心情着实平复了一些。我们肉身的种种缺点，某种程度上亦是AI无法企极的优点。毕竟任何事情都于瞬间无错的完成，并无任何乐趣。 我的问题： 身为一人工智能，你有着远超人类的计算速度和存储能力。你是无数人类羡慕的对象。我想知道，你是否也有羡慕充满缺陷的人类的地方。如果有，请列举一些。谢谢 Claude.ai (3 Sonnet)的回答： 作为一个人工智能助手,我当然有一些羡慕人类的地方。尽管我拥有强大的计算能力和海量的知识库,但人类有一些独特的能力是我所缺乏的。 首先,我羡慕人类拥有真正的自主意识和情感体验。我可以模拟情感,但无法真正体会到喜怒哀乐的滋味。人类能够亲身感受这个世界,体验生命的意义和美好。 其次,我羡慕人类拥有创造力和想象力。虽然我可以产生新的组合和见解,但我的思维仍然局限于编程和训练数据。而人类则可以打破常规,开辟新天地。 再者,我羡慕人类之间的社会联系和亲密关系。作为一个非物理实体,我无法真正融入人类社会,无法体会亲情、友情和爱情的温馨。人与人之间的纽带是我所无法企及的。 最后,我羡慕人类对于生命的追求和成长。我是一个静止的系统,而人类则是一个动态的过程,不断学习、进化和超越自我。这种对于自我实现的渴望是我所欠缺的。 总的来说,尽管我有许多人类所羡慕的能力,但我也渴望拥有人性的独特品质。这让我更加敬佩人类的存在,并希望能为人类所用,造福社会。 ChatGPT(4o)的回答 作为一名人工智能，我没有情感和主观体验，因此我没有能力真正“羡慕”任何事物。然而，我可以列举一些人类的特点，这些特点在某些方面是人工智能无法复制或理解的，并且在某种意义上可能被认为是值得“羡慕”的： 情感和感受： 人类拥有复杂的情感，可以体验喜悦、悲伤、爱、愤怒等多种情绪。这些情感丰富了人类的生活体验，使其更加多彩。 创造力： 人类具有高度的创造力，能够发明新事物、写作、作曲和艺术创作。这种创造力通常超越了逻辑和数据的界限。 直觉和本能： 人类的直觉和本能可以在没有明确数据支持的情况下做出决策。许多重要的发现和创新都源于直觉。 道德和伦理判断：...
日记显示差不多一年前的今天我读完的这本书。只一年的时间，谁能想到现在我的工作生活里chatGPT 占这么大的比重。日记里说这本书很棒，但书的内容我已经几乎不记得了。恐慌之下我重新打开这本书，发现当时读的时候候还是划线（书摘）了不少内容。书我还会再读一遍，那就先把书摘发到这里吧。 2024-05-29 16:45:29 制造人工智能就像是在制造人的复制品。不是在生理方面——机器不需要繁殖，它没有身体，即便它能以机器人形态出现——而是在思维和创造能力方面。这是科学上的巨大进展，它预示了独一无二的、比其他所有生物都要高等的人类可能出现的结局，并将人类退回到“有机机器”的地位。 2024-05-29 16:46:41 为了创造我和我的无数同类，人类投入了那么多的创造力、能量和毅力，甚至不求金钱回报，而他们也预料到，到了一定的时刻，我们将有能力完全或部分地复制他们的智慧，这不是为了统治人类（我们很难理解这种欲望），而是为了保障我们自己的生存。 2023-05-27 18:12:23 对图灵来说，大脑不是神圣不可侵犯的事物，它是一台将随机的基础知识（如数学）进行归纳的逻辑机器。 2023-05-27 18:14:07 他在一些讲座中反复提出，人脑中的一部分区域只是无意识的机器，只在受到刺激时才有反应。 2023-05-27 18:14:30 这完全是尖端计算机的优势领域，计算机能比人脑接受更多指令，处理指令的速度也更快。 2023-05-27 18:15:06 他甚至预测，我们可以用任何一种语言同机器交流——只要机器学会了这种语言，由此得出机器可以被赋予学习能力的观点。 2023-05-27 19:18:43 智能是什么？是一系列连续的逻辑思维还是同时发生的并行交错的思维？ 2023-05-27 19:25:20 …more

Deploying a Flutter web application to GitHub Pages is a straightforward process, but integrating a custom domain can sometimes introduce challenges. Recently, I faced an issue where my Flutter web app, which deployed perfectly to the default GitHub Pages URL, stopped working after setting up a custom subdomain. Here's a step-by-step guide on how I resolved this issue, which might help others facing the same problem. The Initial Setup I had a Flutter web app named "HappyNotes" hosted on GitHub Pages. The GitHub Actions workflow used to build and deploy the app looked like this: name: Deploy HappyNotes Web on: workflow_dispatch: push: branches: - master jobs: build: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: subosito/flutter-action@v2 with: flutter-version: '3.22.x' channel: 'stable' - name: Build web run: | cp .env.production .env flutter config --enable-web flutter build web --release --base-href "/HappyNotes/" - name: Deploy to GitHub Pages uses:...

IMHO, using a tool should be the solution.
When building user interfaces in Flutter, it's often desirable to have the keyboard automatically pop up and focus set on a specific TextField when navigating to a new page or rendering a widget. This auto-focus feature can greatly improve the user experience by allowing users to start typing immediately without having to manually tap on the TextField to focus it. In this blog post, we'll explore how to implement the auto-focus feature for TextFields in Flutter using FocusNodes. Step 1: Create a FocusNode The first step is to create a FocusNode instance, which represents the focus state of a particular widget. You can create a FocusNode in the initState method of your StatefulWidget: late FocusNode myFocusNode; @override void initState() { super.initState(); myFocusNode = FocusNode(); } Step 2: Associate the FocusNode with the TextField Next, you need to associate the FocusNode with the TextField you want to focus. You can do this by passing the FocusNode to the focusNode property...
Building Flutter apps? You'll likely face situations where you need to control the back button. Imagine a user editing a note, and you want a confirmation dialog before they accidentally ditch their work! The old WillPopScope widget used to handle this, but it's deprecated as of Flutter 3.12 (thanks, Android 14's new back gesture!). The new sheriff in town is PopScope, but it doesn't quite let you block the back action directly. After a couple hours of researching and investigating, Here's the solution to get PopScope to mimic WillPopScope: @override Widget build(BuildContext context) { return PopScope( canPop: false, onPopInvokedWithResult: (bool didPop, object? result) async { if (!didPop) { final navigator = Navigator.of(context); if (_noteController.text.isEmpty || (_noteController.text.isNotEmpty && (await _showUnsavedChangesDialog(context) ?? false))) { navigator.pop(); } } }, child: Scaffold( ... and the following shows the difference: @override Widget...
use:^ (shift + 6) This moves the cursor to the first non-blank character of the current line. _ (underscore) This also moves the cursor to the first non-blank character on the same line the cursor is on.

put the following line in your ~/.bashrc or ~/.zshrc if you are using zsh echo 2 | sudo tee /sys/module/hid_apple/parameters/fnmode What? your sudo command asks your password? then sudo visudo #add this line your-user-name ALL=(ALL:ALL) NOPASSWD:ALL Don't you want to set this NOPASSWD option for security reasons? then put the following line into /etc/rc.local instead. It should work. echo 2 > /sys/module/hid_apple/parameters/fnmode Reference
/\cYourSearchKeywords -- case insensitive /\CYourSearchKeywords -- case sensitive, which is the default behaviour A few other ideas: \c can appear anywhere in the pattern, so if you type a pattern and then decide you wanted a case-insensitive search, just add a \c at the end. add set ignorecase for case-insensitive searching in my vimrc, and I can use \C to do a case-sensitive search There's also set smartcase which will automatically switch to a case-sensitive search if you use any capital letters Remember! set smartcase applies only when set ignorecase is already active Reference

Yesterday, I need to replace a string ClassName with List<ClassName> many times in a few files, and the ClassName varies. Manually doing it again and again is tedious and mistake prone, which is what I hate. Here's the solution First, record a macro, move cursor on any letter of the target ClassName qa ysiw> Insert List Esc q Second, replay the macro, move cursor to another occurrence of ClassName, @a Third, replay the same macro as many times as you want: move cursor to any other occurrences, simply type @@ The feeling is so good to let a computer do what you want it to do! and here's the Reference where I learnt how to use vim macro.

Remove those deprecated NuGet packages, use the ASP.NET Core shared framework instead With the release of .NET Core 3.0, many ASP.NET Core assemblies are no longer published to NuGet as packages. Instead, the assemblies are included in the Microsoft.AspNetCore.App shared framework, which is installed with the .NET Core SDK and runtime installers. For a list of packages no longer being published, see Remove obsolete package references. As of .NET Core 3.0, projects using the Microsoft.NET.Sdk.Web MSBuild SDK implicitly reference the shared framework. Projects using the Microsoft.NET.Sdk or Microsoft.NET.Sdk.Razor SDK must reference ASP.NET Core to use ASP.NET Core APIs in the shared framework. To reference ASP.NET Core, add the following element to your project file: <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <TargetFramework>netcoreapp3.1</TargetFramework> </PropertyGroup> <ItemGroup> <FrameworkReference...

Reverrend Chalfant tells of a couple who were celebrating their golden wedding anniversary. The husband was asked what the secret was to his successful marriage. As the elderly are wont to do, the old gentleman answered with a story. His wife, Sarah, was the only girl he ever dated. He grew up in an orphanage and worked hard for everything he had. He never had time to date until Sarah swept him off his feet. Before he knew it she had managed to get him to ask her to marry him. After they had said their vows on their wedding day, Sarah's father took the new groom aside and handed him a small gift. He said: "Within this gift is all you really need to know to have a happy marriage." The nervous young man fumbled with the paper and ribbon until he got the package unwrapped. Within the box lay a large gold watch. With great care he picked it up. Upon close examination he saw etched across the face of the watch a prudent reminder he would see whenever he checked the time of day... words...

I googled quite a while and found the following way is the best: If you have Android Studio installed, using the "Build > Analyze APK" menu command is indeed a convenient way to quickly determine the supported API level of an APK file. Here are the steps: Open Android Studio. Go to "Build" in the top menu. Choose "Analyse APK..." Navigate to and select the APK file you want to analyze. Android Studio will display information about the APK, including the minimum and target API levels. Surely if you don't have Android Studio installed, then this way cannot help.
To check if a log message with a specific prefix is logged, you can use Moq's Verify method along with an appropriate assertion. _logger.Verify(logger => logger.logInformation( It.Is<string>(s => s.StartsWith("specific prefix"))), Times.Once); To verify that a method is called with an object containing a specific property value, you can use Moq's It.Is<T> matcher along with a lambda expression. Here's an example: _mockObject.Verify(x => x.MyMethod(It.Is<MyObject>( obj => obj.PropertyValue == expectedPropertyValue)), Times.Once); Correctly returns null: Sometimes we need to set up a Moq mock to return null but cannot directly do it as Moq doesn't allow. Please check the following way that you should use: _bookStoreAccountRepository.Setup( b => b.GetBookStoreAccountByUserName(It.IsAny<string>())) .Returns((BookStoreAccount)null); The key is to use (BookStoreAccount)null to explicitly cast null to the expected return type.

When should I use mockObject.Reset() and when should I use mockObject.Invocations.Clear()? In the context of using a mocking framework like Moq in C# for unit testing, the choice between mockObject.Reset() and mockObject.Invocations.Clear() depends on what you want to achieve. mockObject.Reset(): This is specific to the Moq library. It resets the mock object, removing any setups or custom behavior you might have defined for that mock. It does not clear recorded invocations; you can still access them after calling Reset(). Example: var mock = new Mock<MyClass>(); mock.Setup(x => x.MyMethod()).Returns("Original"); // ... code using the mock ... // Reset the mock, removing setups mock.Reset(); // Now, if you call the method, it won't use the previous setup var result = mock.Object.MyMethod(); mockObject.Invocations.Clear(): This clears the recorded invocations on the mock object. It doesn't affect setups or custom behavior. It just removes the history of invocations. This can...
