New great Features in iStocks 0.3.0

iStocks MiniI have been busy with enhancing the iStocks dashboard widget. Thanks a lot for your valuable input; most new features were taken from your comments. The new 0.3.0 release has features such as Sorting by performance, Multiple instance support and color themes. It is also possible to rename the symbols and reorder them. And last but not least, the chart fetching has become much more robust by using several fallback data sources.
Check it out at iStocks Widget.

iStocks Dashboard Widget ready for Leopard

iStocks MiniMy upgrade to Mac OS X 10.5 Leopard has been successful without any glitches. I had even spare time to update my iStocks Widget to v2.0. It is now ready for Leopard but works also in 10.4. It has some new features based on the feedback, including support for stocks, futures, mutual funds, indices and currencies like “EUR=X”. It has an integrated symbol lookup facility and ships multilingual. Check it out.

iStocks Dashboard Widget: International Stock Quotes

Tracking stocks can be fun on the Mac, thanks to the Dashboard. However, my home stock market is Germany and Apple’s Stocks dashboard widget, which comes with Mac OS X 10.4, only displays quotes and charts of US stocks. (Actually it’s a limitation of Apple’s quote server and not of the code.) There are 2200 registered widgets available currently, with some dozens of them related to international stock markets. It’s sad, but none of these widgets were as nice or useful for me as Apple’s.

iStocks MiniSo, with a little time to spare today, I’ve completed a small hack which I had on my Todo list for quite a long time. iStocks Widget is a modification (aka patch or clone) of the original Stocks widget which pulls its stock information from the international Yahoo quotes servers. So basically, you can track any stock as long as there’s a corresponding Yahoo symbol. The symbols usually carry information about the stock exchange location, like “SIE.DE” is Siemens, XETRA, Germany.

I’ve put the release at 0.1, since I’m not quite sure if the Yahoo URLs are stable. I’ve tested it against some random stocks (which all worked fine). BTW, you will notice that the intraday and weekly charts are images from Yahoo (they are not rendered via Quartz as the rest). The problem here is that 15-minute and hourly quotes are not available yet for international stocks. I think Yahoo is about to provide them when its new Yahoo Finance Charts will be announced officially.

Incredible 2D Images using NodeBox (Intel Binary!)

Recently, I’ve been busy exploring 2d graphics algorithms for generating great looking logos, wallpapers, and backgrounds. The article “Blog Redesign” drew my attention to a great tool on Mac OS X. NodeBox is an open-source application for programming 2-dimensional graphics and animation in the Python language. NodeBox lets the user focus on coding graphics without worrying about the underlying technology.

NodeBox ScreenshotIt is based on another open-source project, DrawBot, and is inspired by technologies like OpenGL and PostScript. This means NodeBox is based on vector graphics rather than pixels. As such it’s an excellent tool for generating 2D graphics intended for print, and in particular typographic experiments. NodeBox can generate PDF documents that can easily be used in Adobe Illustrator or any professional vector graphics package. NodeBox can also generate QuickTime movies for animations.

If you’re curious, the NodeBox Gallery shows off some good-looking sketches. Tom de Smedt, one of NodeBox’s authors, has published two good examples: Supercurly uses the modular font Superveloz by Andreu Balius to construct organic compositions, while Photobjects is a database of images which can be queried for images connected to certain keywords. These are then used to create randomized collages of images.
Prism is an algorithm for creating a color palette on any subject. It uses the internet as a semantic database.

NodeBox is available in version 1.0 release candidate 7, and is sophisticated enough to count as a real production tool. However, NodeBox is compiled only as a PowerPC binary for Mac OS X. As a proud owner of a new Intel-based Macbook, I’ve been looking for a way to compile the source (included in the download) as a binary for Intel-based Macs.

So read on for the required steps to compile and build it yourself, or just download my build, NodeBox 1.0rc7 Intel Binary for Mac OS 10.4.
