If you’ve ever asked “what’s in C++17 and what does it mean for me and my code?” — and I hope you have — then this book is for you. Now that the C++ standard is being released regularly every three years, one of the challenges we have as a community is learning and absorbing the new features that are being regularly added to the standard language and library. That means not only knowing what those features are, but also how to use them effectively to solve problems. Bartlomiej Filipek does a great job of this by not just listing the features, but explaining each of them with examples, including a whole Part 3 of the book about how to apply key new C++17 features to modernize and improve existing code — everything from upgrading enable_if to the new if constexpr, to refactoring code by applying the new optional and variant vocabulary types, to writing parallel code using the new standard parallel algorithms. In each case, the result is cleaner code that’s often also significantly faster too. The point of new features isn’t just to know about them for their own sake, but to know about how they can let us express our intent more clearly and directly than ever in our C++ code. That ability to directly “say what we mean” to express our intent, or to express “what” we want to achieve rather than sometimes-tortuous details of “how” to achieve it through indirect mechanisms, is the primary thing that determines how clean and writable and readable — and correct — our code will be. For C++ programmers working on real-world projects using reasonably up-to-date C++ compilers, C++17 is where it’s at in the industry today for writing robust production code. Knowing what’s in C++17 and how to use it well is an important tool that will elevate your day-to-day coding, and more likely than not reduce your day-to-day maintenance and debugging chores. If you’re one of the many who have enjoyed Barteks’s blog (bfilipek.com, frequently cited at isocpp.org), you’ll certainly also enjoy this entertaining and informative book. And if you haven’t enjoyed his blog yet, you should check it out too… and then enjoy the book.

一个基站单验，一般包含以下几种业务： ATTACH（附着）、 DETACH（去附着）、 上传、下载、 ping、 DT 路测等。 一般一个宏站，三个小区，每个小区找到一个好 点， 需要做如下定点测试： attach/detach（记一个 LOG）； ping（大包和小包各记 一个 LOG）； 上传（记一个 LOG，并截图）； 下载（记一个 LOG，并截图）。每个小 区除了定点测试外，还需要进行路测（DT）， 路测包含的内容是： 上传（记一个 LOG，并截图）； 下载（记一个 LOG，并截图）。 上面提到的 LOG， 是指在测试过程中， CDS 软件中可以通过记录 LOG， 将整 个测试过程的数据保存下来， 便于测试完成后，在后台进行回放和分析。

1. PostgreSQL的学习心得和知识总结（五十九）|内核级自上而下完美实现PostgreSQL数据库 新增表权限实现列数据无权访问 的实现方案 2. PostgreSQL 14.1 内核

LIO-SAM-DetailedNote LIO-SAM源码详细注释，3D SLAM融合激光、IMU、GPS，因子图优化。 LIO-SAM的代码十分轻量，只有四个cpp文件，很值得读一读呢。 关于LIO-SAM的论文解读，网上已经有很多文章啦，同系列的LOAM、A-LOAM、LEGO-LOAM等，在网上都可以找到相关的解读文章。所以本文旨在对源代码进行阅读学习，积累一些工程上的经验。这里记录下来，希望可以帮到有需要的同学，如有错误的地方，请您批评指正。 :) 如果对您有帮助，帮我点个star呦~ 目录（知乎） 整体流程 代码结构图 因子图 1、激光运动畸变校正。利用当前帧起止时刻之间的IMU数据、IMU里程计数据计算预积分，得到每一时刻的激光点位姿，从而变换到初始时刻激光点坐标系下，实现校正。 2、提取特征。对经过运动畸变校正之后的当前帧激光点云，计算每个点的曲率，进而提取角点、平面点特征
