Here’s an essay by Sussman talking about borrowing ideas from AI and biology to build robust systems. I don’t pretend to understand all of what he is getting at but he does present some nice and different ideas how the future of engineering robust software could evolve.

It is full of little gems to make you think. I am no aware of the state of the art of robust software design for instance software made for the medical and aviation industry but I suspect his views may not necessarily be held by those industries. I doubt that worries him as he is an academic looking to the future, he probably thought of the essay as a shot at raising awareness that ideas are around to be tried out.

Here is the essay

I have a love hate relationship with emacs, for the past few months working with clojure and emacs has been fun. As my programs start to grow in size I feel the need for a more integrated IDE.

My eye turned to enclojure, it is certainly in early stages and it seems the selection of keyboard shortcuts seems a little bit wrong to say the least. They map to the ubuntu change screen shortcut and some even map to keyboard shortcut already defined in netbeans.

It is also quite buggy.

Having said that is does work and has potential. After one night use if seems, err, usable. I look forward to some updates to it. Over the next couple of weeks I shall use it as my default editor and see how it goes.

I did actually try to download and compile the code for the plugin, with perhaps an eye to seeing if I could fix some of the bugs. They don’t seem to have placed all the dependencies into their subversion repository and tonight I was not in the mood for manually downloading jar files. Come on guys make it easy for others to build your code.

I have in the past written a few game applets in Java. Nothing major, often I am just scratching an itch so to speak. One element that perhaps slightly surprised me was how badly applets have been supported in the web gaming world.

Everywhere you look there are web gaming websites that use flash but very little in the way of support for Java applets. It is understandable as applets have had some real issue in terms of compatibility/stability with different browsers.

Programmers that make games in Java and publish via the applet route have traditionally have had to set up their own site and then attempt to get on various link sites in the hope of driving some traffic.

There have been a few small portal like sites, for example www.javagametome.com,

Things are gradually starting to change. In part because Sun has put a bit of effort into applets and made them less broken. And in part because while flash is still very much number one it is starting to face competition from Silverlight, Java and heck even JavaScript is getting more capable. Gamejolt.com seems to have been pushing itself as a place that does not mind what language you use. Games4J are also doing the same thing although I think their publicity has been slightly lower key, They started out as a applet only site but now accept flash. With luck these will be successful enough that at least some other websites with start to accept Java applets.

Note: When I say Java I actually mean any language on the JVM.

With the release of Wordpress 2.8 I am briefly thinking about what additional features I would like. So in order of preference.

1. A vector graphics editing package built in. This would greatly improve my workflow. I often want to include some vector based diagram in a Blog post but the barrier to creating one, exporting it as a png, uploading it and finally having to import it into the post is just to much hassle. A simple built in vector graphics editing tool would really help add some clarity to my posts and help with he work flow.
2. Math symbol rendering. Yes plugins exist, but I am never quite sure which one to use and how long it will be supported for. Will it work with new versions of WordPress? I don’t know the answers so by default I would prefer too not rely on a plugin for things essential to my blog.
3. Code highlighting built in. Pretty much for the same reason as the math symbol rendering really.
