EDIT: If you have non-ascii chars you also want to escape, for inclusion in another encoded document that uses a different encoding, like Craig says, just use:
data.encode('ascii', 'xmlcharrefreplace')
Don't forget to decode dat...
How to get all properties values of a JavaScript Object (without knowing the keys)?
...lues = obj => Object.keys(obj).map(key => obj[key]);
which you can now use like
// ['one', 'two', 'three']
var values = Object.values({ a: 'one', b: 'two', c: 'three' });

How to grep a text file which contains some binary data?
...binary files are treated differently:
When searching binary data, grep now may treat non-text bytes as line
terminators. This can boost performance significantly.
So what happens now is that with binary data, all non-text bytes
(including newlines) are treated as line terminators. If you wan...

SQL injection that gets around mysql_real_escape_string()
...5.6 by default: big5, cp932, gb2312, gbk and sjis. We'll select gbk here.
Now, it's very important to note the use of SET NAMES here. This sets the character set ON THE SERVER. If we used the call to the C API function mysql_set_charset(), we'd be fine (on MySQL releases since 2006). But more on wh...
