Use DRAKON to Generate Code from Flowcharts


It's 1986. You're working on the Russian's Buran space programme - trying to create a re-usable space vehicle which will exceed the capabilities of the American's "Space Shuttle". There's a problem. You have very complicated real-time algorithms which you need to review, improve, optimise, and then turn into code. How do you do it? Obviously, you invent DRAKON! ДРАКОН, "dragon" Backronym for "Дружелюбный Русский Алгоритмический язык, Который Обеспечивает Наглядность." Translation: "Friendl…

The Python Pals Program A Problem


As mentioned earlier, I've been inspired by the Byte Brothers to create a mystery story which kids have to solve using their l33t h4x0r skillz in Python. This is loosely based on The Byte Brothers Go to a Getaway, by Lois and Floyd McCoy. My well-thumbed copy was printed in 1984. I'm not sure when I got it, but I remember being around 8 or 9 when I first started writing programs in BASIC. Sadly, BASIC is as outdated as the Lascaux Cave Paintings, so I've written this in more friendly…

API Design is UI for Developers


Scrap of JSON which doesn't say much.

I've been thinking a lot about APIs and their design recently. I stumbled on this fantastic quote from Greg Parker: Greg Parker@gparkerA programming language is a user interface for developers. Language authors should learn from HCI principles.❤️ 41💬 6🔁 019:10 - Wed 22 February 2012 When I first started learning C++ (back in the bad old days) I was convinced that any 1st year student could design a better programming language. One which behaved in a sane fashion without a lot of legacy cruft…

Getting Images from a Foursquare Checkin


Photo of a MacBook. The decal sticker is of Iron Man. His hand blaster is replaced with the Apple logo.

"Oi!" shouted Whatleydude, "Get Dabr to show images from foursquare checkins!" "Righty-ho sir!" I said. I started coding furiously. Of course, things are never quite as simple as I first thought.... So, how do we go from http://4sq.com/fgIWov to 1 Expand the URL Get your Bit.ly API Key. http://api.bitly.com/v3/expand ?shortUrl=http://4sq.com/fgIWov &login=YOUR_BIT_LY_USERNAME &apiKey=YOUR_BIT_LY_API_KEY &format=txt You can, if you prefer, get the info back in JSON or XML.…

Twitpic OAuth - I'm Stuck


Logo of TwitPic.

Twitpic has implemented an OAuth API. No more having to hand out passwords to all and sundy. Only I'm too much of a dunderhead to get it working. Perhaps it's a combination of heatstroke or this rotten head-cold, but I just can't see what I'm doing wrong. Any help much appreciated. The easy bit. It's easy to post the data to Twitpic $media_data = array( 'media' => '@'.$_FILES['media']['tmp_name'], 'message' => html_entity_decode($_POST['message']), 'key'=>'123465789132465' );…
