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
at first the E-language has corresponding English version, but that seems dead.

Proper Date Format on Websites
publishers and blog writers, don't use a stupid date format such as “10.07.14” or “10/07/14”, or any of the slash. Use this format:
2015-01-08, and this format only. This is a standard.
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.
See: [That Unpatchable USB Malware Now Has a Patch … Sort Of By Andy Greenberg. At http://www.wired.com/2014/10/unpatchable-usb-malware-now-patchsort/ , accessed on 2015-01-08 ], and its links.
