'Users hate change'

This week NN Group released a video by Jakob Nielsen in which he attempts to help designers deal with the problem of customers being resistant to their new site/product redesign. The argument goes thusly:

  1. Humans naturally resist change
  2. Your change is for the better
  3. Customers should just get used to it and stop complaining

There's slightly more to it than that, he caveats his argument with requiring you to have of course followed their best practices on product design, and allows for a period of customers being able to elect to continue to use the old site, although he says this is obviously only a temporary solution as you don't want to support both.


Quick Tips for Fast Code on the JVM

I was talking to a coworker recently about general techniques that almost always form the core of any effort to write very fast, down-to-the-metal hot path code on the JVM, and they pointed out that there really isn't a particularly good place to go for this information. It occurred to me that, really, I had more or less picked up all of it by word of mouth and experience, and there just aren't any good reference sources on the topic. So… here's my word of mouth.

This is by no means a comprehensive gist. It's also important to understand that the techniques that I outline in here are not 100% absolute either. Performance on the JVM is an incredibly complicated subject, and while there are rules that almost always hold true, the "almost" remains very salient. Also, for many or even most applications, there will be other techniques that I'm not mentioning which will have a greater impact. JMH, Java Flight Recorder, and a good profiler are your very best friend! Mea

Setting up a secure VPN with strongSwan on debian

With heightening concern regarding the state of internet privacy (fuelled in part by the passing of the Investigatory Powers Act in the UK), I have set up a VPN server on the virtual server I have hosted with Mythic Beasts. This uses strongSwan and certificate-based IKEv2 authentication.


  • Debian Jessie server already set up and accessible via, a public IPv4 of and a public IPv6 of 2001:db8::1
  • Client username of me
  • Clients are running the latest versions of macOS and iOS (Sierra and 10 respectively at the time of writing)
  • No need to support any other operating systems (although the setup is easily translated)

For automated deployment of a similar setup, albeit Ubuntu-based and using ansible for deployment, I recommend you take a look at Algo VPN. I used that project as a basis for my configuration.

JS hoisting by example

JavaScript function hoisting by example

Below are many examples of function hoisting behavior in JavaScript. Ones marked as works successfuly print 'hi!' without errors.

To play around with these examples (recommended) clone them with git and execute them with e.g. node a.js

Notes on hoisting

(I may be using incorrect terms below, please forgive me)
