The Y-axis in an SVG document points towards the bottom of the page, that is the Y value increases the further down the page 
you go. When positioning items in a maths or physics context however it is more appropriate to have the Y-axis pointing up 
the page like a normal coordinate system. We can provide an affine transformation matrix to a g element's transform 
attribute that flips the Y-axis for its children.

Let the value of the viewBox attribute of the document's SVG element equal "0 0 w h". Suppose we want a coordinate system
whose origin is at the centre of the viewbox and whose Y-axis points up to the top of the page.

The One Secret Trick To Becoming A Genius Programmer

Okay, the title of this post is a bit of a lie. There's no one secret trick to becoming a genius programmer - there are two, and they're more habits than tricks. Nevertheless, these kind of 'secret tricks' seem to resonate with people, so I went for this title anyway.

Every once in a while, a somewhat strange thing happens to me. I'll be helping somebody out on IRC - usually a beginner - answering a number of their questions in rapid succession, about a variety of topics. Then after a while, they call me a "genius" for being able to answer everything they're asking; either directly, or while talking about me to somebody else.

Now, I don't really agree with this "genius" characterization, and it can make me feel a bit awkward, but it shows that a lot of developers have a somewhat idealistic and nebulous notion of the "genius programmer" - the programmer that knows everything, who can do everything, who's never stumped by a problem, and of which ther

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.
