The introduction to Reactive Programming you've been missing

So you're curious in learning this new thing called (Functional) Reactive Programming (FRP).

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.

这两天在使用pillow完成图像识别的一个小任务，mac上配置起来还算方便，但是再centos服务器配置的时候遇到一些麻烦，记录下来

方案1：http://pkgs.org/download/tesseract，安装后和训练数据(https://code.google.com/p/tesseract-ocr/downloads/list)无法正常使用，提示actual_tessdata_num_entries <= TESSDATA_NUM_ENTRIES:Error:Assert failed:in file ..\ccutil\tessdatamanager.cpp，官方说法是训练文件不对应，但是安装了三个版本的tesseract都不行

方案2：手动安装，请参考https://www.simpleservers.co.uk/clients/whmcs/knowledgebase/600/Install-Tesseract-OCR-libs-from-sources-in-Centos.html

方案3：使用PUIAS_6_computational源

$ vim /etc/yum.repos.d/puias-computational.repo 粘贴：

wget https://github.com/shadowsocks/shadowsocks-libev/archive/master.zip

unzip master.zip

开始编译

cd shadowsocks-libev*

./autogen.sh

./configure --prefix=/usr && make
