1. This evening: documented Yahoo! Pipes UI in case of sudden shutdown, built first mockup of web dataflow UI using jsplumbtoolkit.com — really excellent library, exactly the right balance between functionality and framework. It gives you a lot but doesn’t dictate how to use it.

  2. Playing with Yahoo Pipes for the first time. This is the UI I’ve been dreaming of for years. The data sources are bogged down with nasty RSS/ATOM semantics, but that’s mostly irrelevant. The important things:

    • Live, context-sensitive debugging. Want to know what the data looks like at a particular point in the graph? Click there. What if I change this parameter? It updates. WHY ARE PEOPLE NOT RAVING ABOUT THIS? THIS IS HUGE!
    • All parameters are programmable, but with the ability to specify defaults
    • Everything is declarative — not only textually, but visually.
    • One-click publish and deploy, with facilities to create basic UI and pre-fill it
    • Ability to clone and reuse pipes — each pipe is a module you can use in other pipes. Take someone elses pipe and view source, change it, reuse it.

    I made a Pipe to convert h-feed/h-entry markup into RSS from scratch in about 15 mins, having never used the tool before (bear in mind also that this is not a tool built for consuming mf2 data structures): Convert Microformats to RSS. The tiny feedback loop the Pipes tool provides, both in deploying, sharing and debugging, enabled Tantek Çelik to find a bug in his site’s markup.

    Again: WHY DOES NO-ONE KNOW ABOUT THIS? If it’s because processing stodgy, outdated, DRY-violating formats is its bread and butter, fair enough. Let’s rebuild this with microformats2.

  3. v0.2.0 update to php-mf2 (BREAKING CHANGES) contains lots of goodness, including

    • support for the new, safe, consistent e-* property parsing rules
    • improved API, parsing mf2 from HTML now only requires one function call
    • PSR-0 namespace update (mf2Mf2)
    • improvements to the way classic microformats are supported
    • vastly improved documentation

    Go get it now from Packagist, or try it out at pin13.net/mf2

    Aaron Parecki looks like it was a success :) Feedback after using the map creation UI: the path tool is amazing for quickly filling up maps, it would be great if it had the option to automatically insert staggered higher-point points, maybe a 20 every 5 and a 30 every 15 or 20. 50s are most fun to place by hand.

  5. Discovery: my enjoyment of running is directly proportional to the amount of thought which has to go into where to put my feet next.

  6. Chrome users: I added installation instructions for , as Google demands payment for submission to the Web App Store and makes it difficult for you to the run software you want to run. Fortunately they’re fine with you dragging+dropping the extension in. Hopefully that makes things easier!
