opinions and rants on software and...things

One of the many changes that Jessamyn suggested for MyKidsLibrary is that the URLs should be comprised of meaningful text rather than just numbers. In addition to being more human-friendly, it is, apparently, an important search engine optimization technique.
Ruby on Rails likes to construct URLs that end with a numeric identifier that is used to look up a specific record in the database. It is an efficient, effective solution, and the software engineer side of me never considered why you'd have it be otherwise. I have come to think of URLs as being things that are as effectively meaningless and worthless to my brain as printouts of UNIX coredumps. I click on links, I bookmark pages, I never pay the slightest attention to URLs. I use tools -- browsers, bookmarking services -- to work with URLs just as I use tools to write software.
Once I decided to go about making the change, I set out to find who else had already done this work. The Rails ecosystem is vast and densely populated; I knew that there was but a very tiny chance that I'd actually have to start from scratch. Sure enough, a little work on Google revealed that there were many candidate solutions. I picked one that looked solid and set about integrating it into my project.
I'm not new to this; I have been a working, salary-earning software engineer for nearly two decades, so I should have been prepared for the documentation to suck. The documentation always sucks. The last time that I read really good, comprehensive documentation was when I was writing code for a VMS system, and I sat right next to the big orange wall. At least, I remember it being good; it's all so long ago that I might be remembering it in a somewhat nostalgic light.
I had to figure out a lot of things that weren't mentioned in the documentation, and while that's not the worst thing, it is still frustrating to see a useful, well-put-together package that stops just short of being perfect. And, really, they all do.
Open Source is invaluable, but in many respects, it reminds me of a Roadside Picnic.
And just to prove that I'm not a hypocritical dick, my next post will include extensive, failproof instructions for configuring and using the wonderful Rails plugin acts_as_urlnameable.

I have been spending a great many evenings working on a web application that will -- some day -- run on AppEngine's Go runtime. Go is a wonderful language, and programming with it is fun in a way that is increasingly uncommon. Still, it is a very new language and good references are rare. Useful documentation for the AppEngine/Go platform is even hard to come by; the so-called "Reference" for the Go interface to the datastore is little more than a few simple examples and a trivial list of API calls. It's disappointing, frustrating and unproductive.
Fortunately, the web is full of smart people who are willing to go out of their ways to share what they have learned, and I am gradually discovering all of them. I will be listing them here for my own reference as well as making the discovery process less difficult for my fellows.
Ugorji Nwoke's Blog is full of great ideas and thoughts about AppEngine/Go and AppEngine as a platform generally. Very smart, interesting guy.
Miek Gieben's Learning Go isn't specifically about AppEngine, but it is an invaluable reference for the GO language.
GoLang Tutorials has some very valuable guides for obtaining a better mastery of Go. If you find yourself feeling a bit confused by something that Go does a little differently than other programming languages (like interfaces) you may well find a well-written and informative post here that will clear the way for you.
So, it is a meager collection at the moment, but I will be adding to it every chance that I get. Also, I hope to be making my own blog a useful resource, as I have a couple of good techniques and ideas that I have come up with while working on my project.
