Writing helps me think.

A developer asked me a seemingly obvious question today: I have an API GET request that requires a JSON body. Is that okay? It’s a good question too. It turns out the answer isn’t as simple as it should be. On principle the answer is, “No, it’s not cool”. A GET is an idempotent request for a resource. You don’t request a resource with a resource (what would that mean?), you request it with a resource identifier. The HTTP spec, however, is unclear on the subject and does not explicitly disallow it (it probably should). ...

I’ve been busy working on visual design bits for work projects this summer. My method is simple: Sketches and storyboards Static mockups (HTML/CSS, some Javascript) Live mockups (to test integration and interactions) Uncovering what a feature means is fundamental to the method. It exposes the nouns and verbs of the problem, and hints at the useful metaphors. The freeform nature of sketching and developing storyboards based on this language helps me focus on figuring out what the things mean, as well as finding their shape and rhythm. I end up working on several different approaches before it’s obvious which ones are workable for the client and product. ...

Friction works against you. It exceeds your ability to progress. It deflates you, stripping your motivation. It’s the hill you see before starting a difficult project. It’s the gravity that pulls you away when interest wanes. I’m starting a small project for a client today. It’s a simple set of improvements to something I built for them last year, using a toolkit I wouldn’t normally use (but one that fit their uses well enough). I had forgotten a lot about the toolkit when quoting on the work, and by the time I remember it’s clear that there are challenges ahead of me. ...

One of my favourite JavaScript features is its literal object notation. It allows you to declare data structures in JSON, which is a very succinct, C-like syntax. You can use this notation to declare SETs, and the a in b syntax to verify a variable is in a set: /* Declare your set as a JSON constant */ var valid_widgets = { 'widget-viewer': 1, 'special-viewer': 1, 'widget-editor': 1 }; /* Fail if something isn't in the set */ if ( ! (options.widget in valid_widgets) ) return false; /* Profit! */ As the in keyword operates on the index of the referred object, we set the value of the constants to 1 (true). A bit of a hack, but it results in a very clean way of checking if something is part of a set of valid values.

Somehow I missed the recent larger EC2 unit sizes: When I saw this, I immediately thought: these numbers will have K, M, and G suffixes within the next 5 years. Compute units will be sold as 88 mega-ECUs. Imagine 88 giga-ECUs? The ECU is similar to our old measure of computing: boxen (except more virtual). The idea of giga-boxen boggles, but is inevitable (boxen is so much more inspiring than ECUs), or maybe it should be boxels? ...
