How to interpolate a string in Perl?
Perl (and some other languages which came after it :-)) have a feature called interpolation, whereby the names of the variables in strings are replaced by their actual values. This is both useful and dangerous (it can easily result in problems like command injection / SQL injection / HTML injection (aka XSS) – as with…

How to make sure that your webserver isn’t blocket by the ISP?
First of all, if it says in your contract that you can’t run servers, doing so may result in your connection being cut, so do this on your own risk! Second of all, I don’t advocate running websites on a home machine. Get a VPS! All this said, if you do run a webserver on…

The other is ordering the numbers…

Mixed links
From taint.org: AWS running Mathematica. Mathematica was one of those programs which I dabbled with in university and found it incredibly cool, especially given my limited mathematical knowledge… Several sites have referenced the post on SecTheory about the influence of web pages on power consumption (for example the Frequency X Blog).

I consider myself spanked 🙂
I was walking along, minding my own business and ranting about Microsoft (or more precisely an MVP – I know, I know, technically they are not part of MS), and them bammmm! The logic police got me! I was shown the error of my ways 🙂 However, being the lighthearted chap that I am, I’m…
