- 26. 限制retry次数,retry间隔指数增加:
- retries = 0; begin service.update(record); rescue VendorDeadlockError ; raise if retries >= 3 ; retries += 1; logger.warn("API failure: #{e}, retrying...");sleep(5 ** retries); retry; end
>> Effective Ruby- 19. reduce方法折叠集合:
- Enumerable模块的类，可对集合进行过滤，遍历和转化。map和select；还有个可以管理一切的方法 reduce(or inject), reduce可以转换结构；接受者，每个元素被调用一次，并产生返回值，累加器。 enum.reduce(0){|accumulator, element| accumulator + element} 0初始值；建议你总是使用一个带有起始值的累加器。 enum.reduce(0, :+);
数组转成Hash; array.reduce({}) {|hash, element| hash.update(element => true)}
users.select{|u| u.age>=21}.map(&:name) 获取大于等于21的names数组。比较低效；
User.reduce([]) {|names, user| names << user.name if user.age >=21 ; names}>> Effective Ruby- And if we hop into our comment, we can set up a broadcast_to for that post. The broadcast_to will broadcast all update made to that comment, whether a new comment is updated or an existing comment is changed in some way or even one deleted, and send it back out to a channel on action cable named after the post association that this comment belongs to!>> Rails 8.0.1 You are in good company
- Now, let's set things up to be dynamic, such that when we add a new comment to one of these, it's going to update the other as well. This is how we use web sockets in Rails using action cable, one of the frameworks that we have to create updates that are distributed automatically without folks having to reload their browser.>> Rails 8.0.1 You are in good company
- Now, let's add a bit of custom JavaScript. Rails by default ships with Hotwire! Hotwire gives you Turbo, which is a way of accelerating page changes and updates is that your application will feel as fast and as smooth as a single page application without you basically having to write any JavaScript at all.>> Rails 8.0.1 You are in good company
- As you can see here, there is now a full WYSIWYG interface for creating the body. It comes with a default set of styles for the toolbar, you can change those, those styles are generated straight into your application, so you can make it look nice for yourself. Let's give some bold and italic text here, you see, that was all that was needed. but I think what's even nicer to look at here is if we do an upload and we add a file, you will see that file gets added with a preview directly to the WYSIWYG editor. And if we save that and we update the post, it is added to the post itself. And that then went through the whole process of doing a direct upload of the file when we dropped it into the editor, that uploads it straight to active storage. And then, we have access to that, and rendering it directly from whatever storage backend active storage is using. In this example , we're just storing on disk, but you could be storing your active storage in S3 or another object storage.>> Rails 8.0.1 You are in good company
- Now you have access to your entire domain model. So if we find the first post that we created, we can update that post straight here from the console, if we hop back, you see, title is now changed from CLI. New command line interface ( CLI)>> Rails 8.0.1 You are in good company
- And as it descends from application record, we can run everything from updates and destroys and what have you. This is also where we're gonna put our specific logic that's particular to this application beyond just the management of attributes.>> Rails 8.0.1 You are in good company

Exported values can then be imported into other programs with the import declaration or dynamic import. The value of an imported binding is subject to change in the module that exports it — when a module updates the value of a binding that it exports, the update will be visible in its imported value.
导出声明用于从JavaScript模块导出值。然后，导出的值可以通过导入声明或动态导入导入到其他程序中。导入绑定的值会在导出它的模块中发生变化——当模块更新它导出的绑定的值时，更新将在其导入的值中可见。>> export-javascript- The Fooocus project, built entirely on the Stable Diffusion XL architecture, is now in a state of limited long-term support (LTS) with bug fixes only. As the existing functionalities are considered as nearly free of programmartic issues (Thanks to mashb1t's huge efforts), future updates will focus exclusively on addressing any bugs that may arise.
Foocus项目完全基于Stable Diffusion XL架构构建，目前处于有限的长期支持（LTS）状态，仅修复了错误。由于现有的功能被认为几乎没有程序问题（多亏了mashb1t的巨大努力），未来的更新将专注于解决可能出现的任何错误。>> Fooocus- Solid Queue:
- Solid Queue Solid Queue replaces the need for not just Redis, but also a separate job-running framework, like Resque, Delayed Job, or Sidekiq, for most people. For high-performance installations, it’s built on the new FOR UPDATE SKIP LOCKED mechanism first introduced in PostgreSQL 9.5, but now also available in MySQL 8.0 and beyond. For more modest needs, it also works with SQLite, which makes it ideal for that no-dependency path to the first HELLO WORLD dopamine hit you get from seeing your work in production right away.
Solid Queue Solid Queue不仅取代了Redis，还取代了大多数人对单独的作业运行框架的需求，如Resque、Delayed job或Sidekiq。对于高性能安装，它建立在PostgreSQL 9.5中首次引入的新的For UPDATE SKIP LOCKED机制之上，但现在MySQL 8.0及更高版本也提供了该机制。对于更温和的需求，它也适用于SQLite，这使其成为您在生产中立即看到您的工作时获得第一个HELLO WORLD多巴胺的无依赖路径的理想选择。>> Rails8- Beyond plenty fast enough for most applications. As a bonus, Solid Cable retains the messages sent in the database for a day by default, which may ease debugging of tricky live update issues.
对于大多数应用程序来说，速度已经足够快了。作为额外的好处，Solid Cable默认情况下会将数据库中发送的消息保留一天，这可能会简化棘手的实时更新问题的调试。>> Rails8- 3. A Turbo Stream update creates a video element on the newcomer's screen for each greeting it receives.
3.Turbo Stream更新为新用户收到的每个问候语在新用户的屏幕上创建一个视频元素。>> webRTC Hotwire and Ruby on Rails- Finally, when a client disconnects from the room channel, a Turbo Stream update removes the media element from the screen. The media controller broadcasts its removal so the room controller can clean up.
最后，当客户端与房间频道断开连接时，Turbo Stream更新会从屏幕上删除媒体元素。媒体控制器广播其移除，以便房间控制器可以进行清理。>> webRTC Hotwire and Ruby on Rails- This triggers the same process as above on the other client: appending a media element via a Turbo Stream update, and starting a webRTC negotiation.
这在另一个客户端上触发了与上述相同的过程：通过Turbo Stream更新附加媒体元素，并启动webRTC协商。>> webRTC Hotwire and Ruby on Rails- The greet action broadcasts specifically to the newcomer, a Turbo Stream update which appends a media element representing the remote client.
问候动作专门向新来者广播，这是一个Turbo Stream更新，它附加了一个代表远程客户端的媒体元素。>> webRTC Hotwire and Ruby on Rails- Got an unscheduled status update from Hermes.>> 火星救援 The Martian (2015) Movie Script
