Programming is Uniquely Difficult
Apr 09, 2007

Engineers of other disciplines often take offense at the claim that software is uniquely difficult. They do have a point. As pointed out by Fred Brooks in hyper-classic The Mythical Man Month, one reason software is hard because software is so uniquely easy.

Why Do We Care What's Special About Programming?
Apr 09, 2007

The first step to attaining wisdom is to understand why special "programming wisdom" is needed in the first place.

It's easy to get the idea that software is easy to create, because it is partially true. Computers get more powerful every year, and we trade in on that power to make programming easier. Every year results in more and better libraries. Changing software is very easy, and it's relatively easy to test compared to an equivalently-complex real-world object. J. Random User can write an Excel macro with a reasonable amount of effort that saves him a lot of time, and early programmers can become excited about what amazing things they can do just by assembling existing libraries and frameworks together which makes everything seem so easy.

This rosy picture is brought to you by confirmation bias, paying attention only to the uniquely easy characteristics and ignoring the things that make it uniquely challenging. Poke past the surface and you find a strange, complicated, chaotic beast. Learning to tame the power requires a lot of experience and wisdom.

What is Programming Wisdom?
Mar 24, 2007

This is the first post of my new BlogBook, Programming Wisdom.

This initial post starts off by discussing exactly what I mean by "wisdom" in the context of programming. Non-programmers may still be interested as it is more about wisdom than programming.

Big Haskell Projects List
Feb 19, 2007

On, I have referred to a list of Big Haskell Projects I'm keeping. I've been keeping it in my head, because it's been short, but I thought I should go ahead and start actually keeping one.

Haskell as a language intrigues me, but I can't help but notice that there aren't a lot of large projects that use it. My intuition suggests that this could be difficult, because I suspect the type system may become increasingly unwieldy. I once asked about this directly, and the results were less than impressive. I'm asking for examples of large projects because concrete results trump my intuition.

In the interests of honesty and transparency, I'm actually going to keep this list in a public place and try to keep it updated as people suggest things until either A: It satisfies me and I start trying to learn Haskell or B: It becomes too much of a time sink, which would basically mean that there are a lot of large projects. That is, my goal is not to keep a list in perpetuity, but just until the point is made.

Update March 8, 2007: This has been up for three weeks now and attracted some attention from some people who really ought to know. I'm willing to say now that pending further updates, I see no compelling reason to believe that Haskell is practical for larger projects. Furthermore, Haskell arrogance is totally unjustified by evidence. It may someday be proven a compelling choice for Real Programming, but there isn't even any significant evidence of that, let alone enough to justify arrogance.

My New Favorite Spam
Feb 17, 2007

I've seen this sort of spam before, but never with such purity, usually only with the Subject or something left unprocessed.

Date: Sat, 17 Feb 2007 16:42:06 -0500
Received: from 192.168.0.%RND_DIGIT (203-219-%DIGSTAT2-%STATDIG.%RND_FROM_DOMAIN [203.219.%DIGSTAT2.%STATDIG]) by mail%SINGSTAT.%RND_FROM_DOMAIN (envelope-from %FROM_EMAIL) (8.13.6/8.13.6) with SMTP id %STATWORD for <%TO_EMAIL>; %CURRENT_DATE_TIME

Also note that the bit starting with %TO_CC_DEFAULT_HANDLER was the beginning of the messaged body, which is also wrong.

I'm actually a little surprised this was detailed enough for me to get it.
