I heard some points of criticism to how React deals with reactivity and it's focus on "purity". It's interesting because there are really two approaches evolving. There's a mutable + change tracking approach and there's an immutability + referential equality testing approach. It's difficult to mix and match them when you build new features on top. So that's why React has been pushing a bit harder on immutability lately to be able to build on top of it. Both have various tradeoffs but others are doing good research in other areas, so we've decided to focus on this direction and see where it leads us.

I did want to address a few points that I didn't see get enough consideration around the tradeoffs. So here's a small brain dump.

"Compiled output results in smaller apps" - E.g. Svelte apps start smaller but the compiler output is 3-4x larger per component than the equivalent VDOM approach. This is mostly due to the code that is usually shared in the VDOM "VM" needs to be inlined into each component. The tr

Read Shape Up by basecamp on a kindle / reMarkable / eReader

Basecamp's new book Shape Up is now available online (https://basecamp.com/shapeup) to read page-by-page.

There is a .pdf version, but that's not the best format for Kindle / other eReaders. Instead, we can convert the page-by-page into an eReader friendly format.

Part 1: Convert to a single page

NOTE: This has only been tested on Chrome

This is how you can conver the react docs to a .ePub / Kindle (.mobi) file to read in an eReader (or eReader app):

Make sure you have Pandoc available (on a Mac, it can be installed by brew install pandoc via Homebrew)
Checkout or download master from the React docs repo [https://github.com/reactjs/reactjs.org]
go to content/docs
run the following commands in a shell (builds one markdown in order of navigation):

echo '' > ALL.md
for i in $(cat nav.yml | grep 'id:' | awk -F:  '{print$2}')
do

发HTTP请求的包

上一个项目经验，当时选了axios

5 Ways to Make HTTP Requests in Node.js

我们主要用 axios，因为它基于promise
上个项目只有一处用了 request, 因为它提供流处理

I've been deceiving you all. I had you believe that Svelte was a UI framework — unlike React and Vue etc, because it shifts work out of the client and into the compiler, but a framework nonetheless.

But that's not exactly accurate. In my defense, I didn't realise it myself until very recently. But with Svelte 3 around the corner, it's time to come clean about what Svelte really is.

Svelte is a language.

Specifically, Svelte is an attempt to answer a question that many people have asked, and a few have answered: what would it look like if we had a language for describing reactive user interfaces?

A few projects that have answered this question:

不同分词器在elastic中的实际效果

介绍不同分词器的文章不少，较经典的有BosonNLP 11款开放中文分词引擎大比拼

可惜这11款分词器只有IK和结巴一直在更新elastic的分词器插件，Boson的插件已经很久没更新

所以加上elastic自带的smartcn 也就只有三种分词器可选。

注1：smartcn基于中科院的ictclas 但用的是1.0，似乎没再更新

Faster Rails tests

Feedback loop speed in one of the biggest contributing factors to overall development time. The faster you get results, the faster you can move on to other things. A fast enough test suite is therefore critical to teams' success, and is worth investing some time at the beginning to save in the long run.

Below is a list of techniques for speeding up a Rails test suite. It is not comprehensive, but should definitely provide some quick wins. This list of techniques assumes you're using minitest, but most everything should translate over to rspec by simply replacing test/test_helper.rb with spec/spec_helper.rb.
