Javascript Detect Chinese and Japanese Characters

ElasticSearch search behavior is so weird. It works well to search any language except Chinese and Japanese, like Chinese “餐馆” and Japanese “大戸屋”. The workaround in front end is add double quotes to those characters. In usually Chinese, Japanese and Korean are named CJK, which are similar, but Korean it seems works fine. So here we discuss about how to detect Chinese and Japanese in JS.

Google UX Engineer Interview

This is total different engineer interview experience, and I was disappointed by the interview because it absolutely not like Google interview style. Maybe another tiny part was I didn’t have chance to say NO to Google :)

curl for ipv6 on ios9

A old ios app is submitted to review with minor changes. But it’s rejected because doesn’t support ipv6 on iOS9. It shows our app cannot access internet in ipv6 setttings. At the beginning I think it’s AWS S3 issue, maybe it doesn’t support ipv6. Later I find it’s curl lib issue after debug. Actually obviously it should be curl lib issue, because in theory nothing needs to be changed for internet access in ipv6.

How To Use PhoneGap To Auto Subscribe

Phonegap was once popular solution to build ios app with web skills. But now there are more better choices, such as React Native or NativeScript, but I think Phonegap’s advantage is a lot of plugins. In the past half year, I spent a lot time to use cordova-plugin-purchase to support auto subscription, though this plugin has some problem and author doesn’t provide server receipt validation code or even explanation, but it seems it is still the best purchase plugin. After a lot struggling, finally I figure it how to do it.
