RubyonRails的一些代码知识点

Bun:

Bun is a JavaScript runtime.Bun is a new JavaScript runtime built from scratch to serve the modern JavaScript ecosystem. It has three major design goals:
Speed. Bun starts fast and runs fast. It extends JavaScriptCore, the performance-minded JS engine built for Safari. As computing moves to the edge, this is critical. Elegant APIs. Bun provides a minimal set of highly-optimimized APIs for performing common tasks, like starting an HTTP server and writing files.Cohesive DX.
Bun is a complete toolkit for building JavaScript apps, including a package manager, test runner, and bundler.

Rails7.1:

Dockfile;own authentication;more async queries, async_count;trilogy：new MySQL database adapter；composite primary keys;perform_all_later;config.autoload_lib;

ConnectionPool:

Opening a new connection is usually an expensive operation. Connection to RabbitMQ is done with TCP protocol. Creating a new one requires many steps, such as DNS lookup, TCP handshake, TLS handshake, authentication, etc.

Ahoy:

When someone visits your website, Ahoy creates a visit with lots of useful information.
traffic source - referrer, referring domain, landing page
location - country, region, city, latitude, longitude
technology - browser, OS, device type
utm parameters - source, medium, term, content, campaign
.

utm:

https://example.com/?utm_source=facebook.com&utm_medium=display&utm_campaign=summer+sale+2018.

UTM参数的全名是Urchin Tracking Module Urchin跟踪模块,
流量渠道标记一般是使用UTM，UTM的全称是Urchin Tracking Module/Urchin Tracking Manager，
Urchin是就是Google Analytics的前生.
UTM成为行业术语了，如百度统计、神策、GrowiongIO、诸葛IO都支持或兼容UTM，可以说UTM就是流量跟踪、流量标记的代名词.
utm_campaign：表示广告系列，就是广告活动的名字

Nokolexbor是Nokogiri的替补。它在解析HTML方面快5.2倍，在CSS选择器方面快997倍。

Passwordless:

A system to add password-free ‘magic link’ style authentication to your Rails apps.

Personal growth stuck:

Hey folks!

I'm Ruby/Rails developer with 5 years of experience. I want to become a senior developer but I feel like I'm stuck and not sure where should I go. Some thing became boring and routine, and I want to learn something on the basis I already have, but there are so many new things. It's confusing me . I would be appreciate for any advise. Peace!

Horizontal investments:

learn django, laravel, and/or spring boot. (other backend battery included frameworks with different philosophies). If you a hardcore ruby main, elixir/phoenix it is. Or learn Vuejs (a frontend framework that is quite compatible for those coming from ruby/php/python/golang).

Vertical investments:

try out 4 nosql databases/7 db paradigms, GraphQL, microservice + golang, kubernetes.

By building smaller parts, one at a time, you can change directions as you get to higher-level components after you build a solid lower-level foundation.

You set out to test a single object and end up with a whole sub-system.

Feedback Loops:

A tight feedback loop is a game changer. Shortening your feedback loop will always pay dividends. Here are a couple of tools I use to shorten mine.

I highly recommend watching this talk from one of Test Double’s founders, Justin Searls — especially the section starting at 31:52 where he does the math on the importance of feedback loop. If it doesn’t make you obsessed with its importance, nothing will!
