Virtual Agility
Ron Teitelbaum talks about how Teleplace supports agile development - no matter how far flung your development team is.
Building Clean
Before you can even get to building a runtime image from a clean base image, you have to get to the point where yoiu can build a clean development image from a clean base image. That was today's first challenge.
On any long lived project, things pile up if no one has been doing clean builds, and this one was no different. It wasn't bad - I only ran into one issue that needed resolving: four methods in one package were being invoked (via package initialization code), but those methods were defined in a package that hadn't loaded yet.
To back up a bit, the entire project here is in a "master bundle" - you load that, and you get everything (either in the bundle or via pre-reqs). Over the last little while, builds have only been done on top of previous development images, so no one spotted this issue. I cleaned that up, and then everything came in easily.
Next up was trying to save the bundle out as a parcel (I'd like to be able to build into an image without Store present). Now I ran into the second check: a bunch of external interfaces were defined with optimization level #debug, and parcels can't be saved with that setting. So... another bunch of small changes and bam - I had a parcel out on disk.
Now comes the fun part - one of the pre-reqs is all of the patch sets that Cincom support sends out (boy, would this be simpler if they just shipped new versions of the owning packages, but I digress). That stuff can't be saved (at least in VW 7.6) as a parcel, because they all contain overrides. So... I just filed that out. Since it's all patches on the base system, I can just set that up to load last and I shouldn't run into problems.
Thus far, I have the system loading cleanly from a base visual.im, which is progress. From there, I can move along to the next few steps and see if I can get a runtime build. Fingers crossed :)

Brief Outage
There was an issue with the service I use overnight (I got a bunch of emails while I slept) - but it's all better now :)
S3 in Pharo
Sven Van Caekengergh has implemented an S3 client for Pharo Smalltalk:
I implemented and published a Pharo client for Amazon's AWS S3 service called ZnAWSS3Client. For some background, see the Amazon docs. The code can be found in the package 'Zinc-AWS' in Squeak Source. It depends on both Zinc HTTP Components and XML Support (an excellent package BTW) as well as on the cryptography functionality in Pharo (md5, sha1 & hmac). Basically, Amazon S3 (Simple Storage Service) is an online storage web service where you store and retrieve objects under keys organized in groups called buckets. Objects can be any web resource identified by a mime type. The main advantage is that S3 is a highly scalable, reliable, secure, fast, inexpensive service.
Moving Back the Chains on Build Tools
I'm still working on build automation - the work I did yesterday got me where I wanted to go for BottomFeeder, but that's because all of the scripts existed already. What I need to get to is this:
- Starting from a development image, specify a set of packages and bundles to include in a build
- Have a tool that takes that information and generates a minimal build script
- From there, be able to execute said build script
And that's what I'm working on today. I've got a simple domain model hammered out - I still need to create a UI to live on top of that as a specification tool. But it's progress :)

More Build Automation
I wanted to move my build script one level further back - meaning, I wanted to have it work like this:
- Fire off an image
- Load all the latest code from Store
- Drop each package/bundle from the image into a build directory
- Fire off a new, clean image, load the parcels, and proceed from there
That way I could ensure that a build actually had the latest code, instead of the latest code I remembered to parcel out - and my build doesn't need any of the Store machinery in it. So, here's the guts of that new script. First, some code to load a package from Store, then dump it out as a parcel:
savePackageBlock := [:name :dir | | pkg | pkg := Store.PackageModel allInstances detect: [:each | each name = name]. pkg saveAsParcel: (dir asFilename construct: name) saveStructure: true saveLinks: true]. (Store.Package newestVersionWithName: 'MyCounter') loadSrc. savePackageBlock value: 'MyCounter' value: 'buildTest'.
That's easily built up to more packages. Then I just add this new script to what I last posted on, and bam - I go from a clean image and an empty build directory to a full build directory and a clean build. Pretty nice :)
The Joys of Bureaucracy
There are advantages to working in a big organization - budgets tend to be looser, the projects tend to well established. On the other hand, getting started can be slow - the wheels of the IT organization turn slowly. I only got my work laptop today, for instance, and it took nearly 30 minutes on hold before the help desk got to my call (they were polite and helpful once I got there though).
It's going to be a bit weird having a machine that I'm not the master of - I don't have admin access to the Windows notebook they gave me. That's why I have my personal Mac though - it's my "real" machine :)
How to Promote
Gemstone gets it - they are actively promoting the new Amazon free EC2 micro-instance as a way of getting started with GLASS. Other Smalltalk vendors, sadly, are in a somewhat different place...

Disintermediation in Books
Richard Fernandez notes that more authors are starting to move away from formal publishing, and doing it themselves - they get to keep a lot more of the money that way. The problem for new authors trying to do the same thing? Visibility:
Maybe Joe Konrath can go direct to his audience. But he’s got a reputation. Authors without an established readership base face a chicken and egg problem. Nobody buys their books because nobody knows about them, and nobody knows about them because nobody has yet bought their books. New print on demand services like Createspace and Amazon’s Kindle have only solved the self-publisher’s logistics and distribution problem, but they have not solved the self-publisher’s more fundamental problem, which is marketing.
That's certainly a problem, but I wonder how much of one going forward. The Amazon recommendation engine has turned over a lot of books for me, many of them self published ones from fairly unknown authors. I've found the quality of those books varies about as much as it does for "professional" authors.
The thing I don't really know is how those authors make the leap from utter obscurity to that recommendation list. Clearly some people are making that jump, but I have no idea how many, or how hard it is.

New Cog VMs
Eliot Miranda has released new Cog VMs - I'm quoting an email to the Squeak list below:
I've released a new version of Cog that has a substantially improved code generator along the lines of Peter Deutsch's HPS (VisualWorks) and various of Ian Piumarta's VMs. These all use a simple tecnique to identify constant references in bytecode and to support a register-based calling convention. While this does produce faster code it tends to accelerate low-level code much more than high-level code
You can download them here - and follow Eliot on his blog here.
Video in Smalltalk
Sean DeNegris continues to do some cool work in Squeak:
I have a working proof-of-concept to play any video file that QuickTime can handle in Squeak Smalltalk (or Pharo with slight modifications).
Evolving Book Norms
Here's something I hadn't thought of with the rise of ebooks - the loss of page numbers. I'm quoting John Holbo, who ponders the issue:
I’m thinking about quoting our John in something I’m writing (yes, on Zizek). But I can’t footnote a Kindle edition. No pages. What will the world come to? Bibliography has gotten a bit old and odd in the head in the age of the internet, but the existence of pages themselves is kind of a watershed.
The Kindle app (and presumably the Kindle as well) show you a "percentage reached" instead of a page number. I understand that - given the various form factors involved (multiple Kindle sizes, iPads, smart phones....), what does a page number even mean? It should be simple to graft the physical form page number into the metadata, but as we go forward, there may well be books for which no physical form exists. What then? Perhaps we'll have to footnote based on the word count of the reference? Some sort of standard will have to arise, I guess.
