App Engine is generally a new paradigm for webapp developers; replacing sessions with memcache and a schemaless datastore just two elements requiring new thinking for old problems. Unfortunately there are a few more hidden nuisances which have the potential to waste programming time relatively early on. Here’s four of my personal head-bangers:
1. the datastore doesn’t always store Properties
I’ve had trouble with it refusing to store arbitrary entity props unless I assign them in the entity constructor itself (these fields were optional btw). Just setting prop values after initialisation then put() on the ds didn’t write them.

Slacktivism has been exposed as a joke.
Half way through last week a nation erupted; the Republic of Ireland football team crashed out of the World Cup at the hand of Gaul, that of a certain Thierry Henry. A Facebook group was established. It took on something of a life of it’s own – over 300k users inside the first 24 hours.
“Something has to be done”.
FIFA made no mention of the incident in their official match report. It was edited several times, each time the Magnum PIs on Twitter reporting to the world the latest breach of instant populist moral values and punch-drunk notions of democracy. Avatars may not have been coloured green, but the online social network air was turning a particularly dark shade of blue and the feedback loop of increasingly agitated noise fed into itself, reaching a deafening cresendo online while steadily losing touch with reality.

Jase Bell made a prediction in his startup column in yesterday’s local press regarding the proliferation of small home-based projects in response to hard times in corporationland:
“With the amount of high-tech skills out there I predict a new wave of micro businesses (with five employees or less) over the next three years. Their sales area will be global instead of local and their areas of expertise will be broad and far reaching.”

This has a resonance somewhat further afield too – the Wall St Journal last week covered the emergence of the app store cottage industry as a growth sector in Silicon Valley. The iPhone and it’s appstore is this sub-industry’s poster boy of a platform built for the masses.
The low cost barrier to entry (SDK is free, while publishing an app costs $99), the ensembled army of early-adopting geeks and the global reach leverage of an appstore listing make for an attractive ecosystem to programmers. This has resulted in an abundance of apps for every conceivable smart phone task. At a guess I’d say the OS provides for 80% of the functions I use my netbook for. A computer in the pocket.
But I don’t like the iPhone.

First of all – thanks Asda for selling it at 32 quid.
Played single player reg through til completion and while it was as polished as you’d expect from the Modern Warfare franchise it failed to eclipse the heart-pounding immersive nervousness of the original’s ghillie-suit level. Also the kablamo’ed White House scenario seemed to be lifted straight from COD5’s Reichstag finale. Ditto with the staggered progression as seen from the eyes of US Army Rangers and their SF counterparts. Personally I find that sort of storytelling disjointed and a distraction.

I posted about Google’s inhouse deadpool a couple of weeks back. Strangely though although I use one of the wordpress sitemap plugins to update mine accordingly Google stubbornly refused to index it. The reason?
Google appears not to add pages that include the rel=”nofollow” meta attribute by default.
