Non-English-based programming languages

some interesting ones, that there are a lot Chinese users. Some are just aliasing the english keywords to Chinese. Here's 2 of them based on Python, But both seems dead:

but more interesting is new languages that are entirely in Chinese for Chinese. One of them, seems very popular, is:Easy Programming Language (易語言) (official site http://www.eyuyan.com/), a visual-basic like language.

Easy Programming Language (EPL, Chinese: 易语言) is a Chinese programming language, featuring a full Chinese environment. Its community may be the largest of all non-English-based programming languages. EPL is popular in China, considering the difficulties of adopting English for most Chinese speakers.

易语言是一门计算机程序设计语言,也通常代指与之对应的集成开发环境,其最大特点是通过汉语进行编程。语法风格类似于 Visual Basic。易语言的创始人是吴涛,早期称为E语言,他曾表示,创造易语言的初衷是进行用中文来编写程序的实践

Unpatchable USB Malware

there is unpatchable malware. The gist seems to be that hackers can alter a USB's firmware, so that when you plug in the USB, it infects your computer, and this is essentially undetectable.

The take-away seems to be: never plugin a usb from untrusted source.
