CloudPlatform Edition Comparison

Edition Overview

• 开发工具：HBuilder X 3.4.7.20220422
• uni-app + Vue3
• 以安卓App的方式运行（iOS和小程序同理）

思路

蓝牙收发数据的逻辑和我们常用的 AJAX 进行的网络请求是有一丢丢不同的。
其中较大的区别是：蓝牙接收数据不是那么的稳定，相比起网络请求，蓝牙更容易出现丢包的情况。
在开发中，AJAX 发起的请求不管成功还是失败，浏览器基本都会给你一个答复。但 uni-app 提供的 api 来看，蓝牙接收数据会显得更加 “异步” 。

• Dev tool: HBuilder X 3.4.7.20220422
• uni-app + Vue3
• Running as an Android app (same idea for iOS and mini programs)

The idea

The logic of sending and receiving data over Bluetooth is a tiny bit different from the AJAX network requests we’re used to.
The biggest difference is this: receiving data over Bluetooth isn’t all that stable. Compared with network requests, Bluetooth drops packets far more easily.
In day-to-day development, whether an AJAX request succeeds or fails, the browser will basically always give you an answer. But judging by the APIs uni-app provides, receiving data over Bluetooth feels much more “asynchronous”.

在构建大数据平台时，Spark、Hive 和 Hadoop 的关系是互补协作而非互斥。选择哪种技术以及如何组合取决于你的具体需求（数据量、处理速度、查询复杂度、成本、团队技能）。以下是如何选择和结合使用的指南：

核心定位与区别

1. Hadoop (主要指 HDFS + MapReduce/YARN):
   • 定位： 分布式存储(HDFS) + 基础资源管理和批处理框架(MapReduce/YARN)。
   • 优势：
     • 高可靠、高容错的分布式存储 (HDFS): 存储海量数据的基石。
     • 成熟的资源管理 (YARN): 协调集群资源（CPU, 内存）供上层应用（Spark, MapReduce, Hive on MR/Tez）使用。
     • 极高的可扩展性和成本效益： 能在廉价硬件上构建大规模集群。
   • 劣势： MapReduce 计算模型速度慢（尤其迭代计算、交互式查询），编程相对复杂。

When you build a big data platform, Spark, Hive and Hadoop are complementary collaborators rather than mutually exclusive choices. Which technology you pick and how you combine them depends on your specific needs (data volume, processing speed, query complexity, cost, team skills). Here is a guide to choosing and combining them:

Core positioning and differences

1. Hadoop (mainly HDFS + MapReduce/YARN):
   • Positioning: distributed storage (HDFS) + basic resource management and batch processing framework (MapReduce/YARN).
   • Strengths:
     • Highly reliable, highly fault-tolerant distributed storage (HDFS): the cornerstone for storing massive amounts of data.
     • Mature resource management (YARN): coordinates cluster resources (CPU, memory) for the layers above it (Spark, MapReduce, Hive on MR/Tez).
     • Extreme scalability and cost efficiency: lets you build large clusters on cheap hardware.
   • Weaknesses: the MapReduce computation model is slow (especially for iterative computation and interactive queries), and programming it is relatively complex.

因为最近在学鸿蒙开发，开发电脑一直用的deepin系统，DevEcoStudio不支持linux系统，用了win兼容引擎还是不行。没办法，只好装了virtualbox来运行win10。

在virtualbox中安装好win10也装了，DevEcoStudio运行后，虚拟机一直提示hyper-v未开启。但是，明明开启了，怎么办？难打VT-X和hyper-v有冲突？查查资料，找到了解决办法。

I’ve been learning HarmonyOS development lately, and my dev machine has always run deepin. DevEco Studio doesn’t support Linux, and the win compatibility engine didn’t help either. So I had no choice but to install VirtualBox to run Win10.

Win10 installed fine in VirtualBox, but after launching DevEco Studio the VM kept saying Hyper-V was not enabled. It clearly was enabled though — so what now? Could VT-X and Hyper-V actually be in conflict? I dug around and found the fix.

自学PLC是完全可行的！关键在于系统化的学习路径+动手实践。以下是为你整理的 「零基础自学PLC全攻略」，结合多年工业自动化经验总结，帮你少走弯路：

一、自学必备基础准备

1. 电工知识（必须掌握）
   • 看懂电路图、继电器控制原理（启保停/正反转）
   • 了解传感器（NPN/PNP接线）、接触器、开关电源等元件
2. 计算机操作
   • 文件管理、软件安装、基础调试能力
3. 逻辑思维能力
   • 能分析“IF…THEN…”条件逻辑

💡 重要提示：若电工基础薄弱，先学习 《电工上岗证》 内容（推荐b站“电工大吴”系列视频）

Teaching yourself PLC is entirely doable! The key is a systematic learning path + hands-on practice. Below is the “Complete Guide to Teaching Yourself PLC from Zero” I put together for you, distilled from years of industrial automation experience, to help you skip the detours:

1. Prerequisites

1. Electrical knowledge (must-have)
   • Read circuit diagrams and relay control principles (start-hold-stop / forward-reverse)
   • Understand sensors (NPN/PNP wiring), contactors, switching power supplies and other components
2. Computer skills
   • File management, installing software, basic debugging
3. Logical thinking
   • Able to reason through “IF…THEN…” conditional logic

💡 Important note: if your electrical fundamentals are weak, start with the “Electrician Work Permit” material (I recommend the “电工大吴” video series on Bilibili)

PHP微服务架构终极整合方案:

The ultimate integrated plan for a PHP microservices architecture:

基于之前的架构设计，进一步提供完整的可落地方案：

一、服务注册中心增强实现（Consul + PHP）

1. 健康检查与自动注销

// 服务注册时增加健康检查端点
$consul->get(AgentInterface::class)->registerService([
    'ID' => 'payment-service-'.uniqid(),
    'Name' => 'payment-service',
    'Tags' => ['primary', 'v2'],
    'Address' => get_current_ip(),
    'Port' => 8000,
    'Check' => [
        'HTTP' => 'http://'.get_current_ip().':8000/health',
        'Interval' => '5s',
        'Timeout' => '2s',
        'DeregisterCriticalServiceAfter' => '30s'
    ]
]);

// PHP健康检查端点实现
$app->get('/health', function() {
    return json_encode([
        'status' => 'UP',
        'db_connected' => DB::connection()->getPdo() ? true : false,
        'redis_connected' => Redis::ping() ? true : false,
        'load' => sys_getloadavg()[0]
    ]);
});

Building on the earlier architecture design, here’s a more complete, ready-to-ship plan:

1. Enhanced service registry implementation (Consul + PHP)

    'Tags' => ['primary', 'v2'],

// The PHP health check endpoint
$app->get('/health', function() {
    return json_encode([
        'status' => 'UP',
        'db_connected' => DB::connection()->getPdo() ? true : false,
        'redis_connected' => Redis::ping() ? true : false,
        'load' => sys_getloadavg()[0]
    ]);
});
