Quoting the Spoofax news page:

We're pleased to announce the release of Spoofax 1.0. A number of significant new features have been added since the last stable release, a long list of bugs has been fixed, and various minor improvements were introduced.

Highlights of the release include:

The new version is now available from the update site at http://spoofax.org/update/stable.

In addition to these features, we're actively working on improving Spoofax with new features. In particular, we are now working on providing full support for debugging, on an interactive shell for Stratego and custom languages, and a new meta-language called !SpoofaxLang to define languages in a more modular fashion.

A full list of feature requests and issues addressed in the new version is provided at http://yellowgrass.org/tag/Spoofax/1.0.

This Tuesday, December 13, 2011, Lennart Kats defends his doctoral dissertation titled "Building Blocks for Language Workbenches" in the Aula of TU Delft. Quoting the introduction:

This dissertation presents research on techniques, methods, and tool support for domain-specific language engineering. Domain-specific language engineering is the discipline of designing, developing, and maintaining domain-specific programming languages. The focus of this thesis is the architecture of language workbenches their underlying technologies. Language workbenches are tools that make language engineering more efficient by providing an integrated development environment for language engineering tasks. In particular, we introduce the Spoofax language workbench, and describe its techniques for high-level, portable language definitions, language composition, interactive support for defining languages, and language testing.

Prior to the defense the TU Delft Software Engineering Research Group organizes a symposium on software language design and engineering featuring talks by Peter Mosses, Oscar Nierstrasz, and Paul Klint.

Chiaroscuro

I got this error message from my Time Machine backup software:

Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you.

Apple support explains this as follows:

Apple has identified an issue on some Time Capsule systems that could potentially make previous backups unavailable. The Time Capsule Backup Update improves reliability of affected Mac OS X v10.6 systems by creating a new backup.

'Creating a new backup' entails wiping the backup disk and creating a new backup from scratch. Backing up of the 400GB data on my harddisk is probably not going to finish before I have to leave with my laptop in the morning, so I will not be backed up while traveling. Furthermore, all previous incremental backups have been wiped, so if I'd want to restore a file deleted a couple of weeks ago, I'm out of luck.

What a beautifully designed paradox!

I'm experiencing more such classical usability problems with Apple products recently. And I'm not even considering upgrading my iPad to iOS 5 after reading beauties such as

"an error occured while backing up this iPad (-48). Would you like to continue to update this iPad? Continuing will result in the loss of all contents on this iPad?"

Almost looks like they had only one guy in QA.

On Thursday and Friday I visited Microsoft Research in Redmond and talked with RISE researchers and the TouchDevelop team about DSLs for mobile application programming. I gave a talk about Mobl and Spoofax, which they recorded. I checked the box for external distribution of the video, not expecting they'd actually publish it, but they did: the video is available online, and here are the slides:
