Continuous Learning Curve: Javascript

I’ve avoided spending too much time delving into Javascript. My four-year switch from Windows-uber-alles (including VFP, VSS, SQL Server, Ingres, Oracle, HTML, OLE, ODBC, SCC, COM, XML, MCSE, MCSD, XSLT, DCOM, RSS, MS Office, Exchange, MAPI Bad, SMTP Good, MVP and more acronyms!) to Linux-Apache-MySQL-Postgres-PHP-Python-Ruby, not to mention XHTML, CSS, bash, Smarty, Django, TWiki, dojo, et al had kept me busy enough. But a new client assignment needs a highly-interactive web site and dropping in great big globs of someone else’s Javascript is not going to solve all the problems; at a minimum, I’ve got to be able to read it, debug it and tune it for the client’s particular needs.

Did you know that a limited version of Safari, the O’Reilly online library, is included with a membership to the Association of Computing Machinery? I’ve been an ACM member for years and been meaning to get around to trying this out. My Javascript studies seemed the perfect occasion. I’m reading Shelley Power’s Learning Javascript online and getting quite a bit out of it. I love when you settle down with a book and start going “Oh, is that what that meant?” or “Now I get it!”

State of the Computer Book Market, Part 4 – The Languages – OReilly Radar

Over at O’Reilly, Mike Hendrickson posts State of the Computer Book Market, Part 4 – The Languages – OReilly Radar. Bear in mind in the world of lies, damned lies and statistics, these are statistics. Like measurements of job posting vs. languages, or web pages vs. languages, these aren’t an indication of what languages are in use out there, or what languages are suitable for use. This is just a measurement of what book titles sold the most, grouped roughly by language. If the best book on your favorite language is years old, it’s probably shown as small here. If a bunch of crappy books got published on the language-of-the-week, and the authors and publishers did a good job of getting a buzz going, it’s probably scoring high. Don’t use this to decide whether to use vi or emacs, tabs or spaces.

But it’s interesting data.

Dabo rocks!

I’ve mentioned it before, but the dabo project rocks! dabo is intended to be a cross-platform (Mac/Linux/Windows/Everywhere) rich-client application (like FoxPro 2.5 before MS bought it) with the rich-client experience (grids, list boxes, checkboxes, pageframes, menus, multiple forms) in the appropriate widget-set for each OS. It supports a slew of backend data sources (MySQL, PostgreSQL, MSSQL, Oracle, more) and is designed with a similar architecture (UI-BizObjects-Data) to many of the FoxPro frameworks. Best of all, it’s written in Python and available under an Open Source license.

I’ve spent a couple days downloading the source, watching the excellent screencast tutorials, browing the extensive mailing list archives and wiki, running the demos, generating an app with the App Wizard and reading the code. I’ve got an existing LAMP application that would benefit from a rich-client component with reporting capabilities, and dabo looks like a good choice. Hope to blog my progress as I get into it.
