Spoon presentation 2012-02-24

Craig Latta — Fri, 24 Feb 2012 14:14:40 +0000

This is a fly-through of my next presentation about Spoon (netjam.org/spoon). I hope to present it at the next Pharo conference, 24-25 May 2012 in Lille, France.

I’m available for work.

Craig Latta — Mon, 20 Feb 2012 14:51:03 +0000

I’m looking for new clients or an employer. Here’s my resume. I’d love to hear from you; thanks!

next steps 2012-02-20

Craig Latta — Mon, 20 Feb 2012 09:42:43 +0000

Thanks for all the feedback on the 3 alpha 3 release! I’m preparing 3a4 now. Sorry for the delay, I had paid-work issues to deal with for the last few months. Speaking of paid work, I’m available for new clients or a full-time assignment. Here’s my resume. I’d love to hear from you!

If you had trouble starting 3a3, please let me know. I’d be happy to get together with you online and debug it together. While Bert Freudenberg’s “all in one” packaging technique for Squeak has made things considerably simpler, it seems there are still ways that the configuration of an individual machine can interfere with successful startup.

The next feature I’m working on is more convenient startup of the history memory from a subject memory. Since this is the execution of a single well-known command, I decided that using OSProcess is overkill. Instead, I’m adding a Flow primitive that forks and execs the appropriate command (and the equivalent action on Windows).

I’ve also submitted a Kickstarter project proposal to fund work on Spoon.

Thanks again for your interest!

Here’s the first draft of my next Spoon presentation. I’d love to hear any feedback you have. Thanks!

Spoon 3 alpha 3 released

Craig Latta — Fri, 19 Aug 2011 15:17:49 +0000

Hey there, I’ve released Spoon 3 alpha 3. I look forward to tearing through a few more alphas in the coming days at ESUG! :) See you soon.

first Naiad module page created

Craig Latta — Sun, 10 Jul 2011 20:08:24 +0000

Naiad is Spoon’s module system. For every Naiad module, there can be a webpage describing it and providing something for Google to crawl. This is the basis of a discovery system for Naiad modules. It includes…

a well-known master Naiad module pages ID (so that one can search the web for all Naiad module pages)
the module’s name
the module’s author’s ID (so that one can search the web for the pages of the modules by that author)
the module’s ID
a description of the module’s content
the module’s current version
the module’s latest timestamp
the module’s tags
the IDs of the module’s prerequisite modules (for which one may search the web)
one or more installation links. When clicked, an installation link hits a webserver running in a local Spoon system. The link contains an encoded hostname and port for a remote Spoon system which actually serves the module.

I created the first Naiad module page, for the “fundamental constants” module. I also made a custom search engine for finding Naiad module pages.

initial Spoon modularization finished

Craig Latta — Tue, 05 Jul 2011 02:04:24 +0000

I’ve finished the initial Spoon modularization. It’s 32 modules, 179 classes, and 1953 methods. The listing on the linked page above is now machine-generated from the modules.

next steps

Craig Latta — Sun, 26 Jun 2011 21:26:00 +0000

Well, the initial Spoon modularization is coming along nicely. It has taken a form which is both human and machine readable, so I’m going to write code which reads it and creates the modules. Then I’ll check for methods which aren’t mentioned, probably removing some more stuff that hasn’t been used recently. Then I’ll test serving a module to another system, and adapt the remote browsing support to Squeak 4.2. The next Spoon release will consist of minimal history and subject memories and VMs (packaged as host-platform applications), remote browsing changes, VM changes, and VM build environments.

It looks like the first non-bootstrap module will be for printing (printOn: etc.).

initial Spoon modularization

Craig Latta — Mon, 20 Jun 2011 22:19:43 +0000

At last! I’ve wanted to see this list ever since I started Smalltalking. Here are the initial modules in Spoon, including the classes and methods they contain, numbered for reference.

How would you sort these classes by dependency?

Craig Latta — Mon, 20 Jun 2011 13:50:41 +0000

Here are the last 168 classes remaining in Spoon. I’m sorting them into a graph of dependent modules for the next release. How would you do it? Suggestions welcome.
