Smalltalk Tidbits, Industry Rants

Can you say "selective enforcement"?

On the last day of the recent Reuters Media and Marketing Summit in New York, Warner Music Group CEO admitted that he was "fairly certain" that one or more of his seven children had downloaded music without the permission of the copyright owner, which Reuters referred to as stealing.

Despite the alleged infringers' proximity to the major label head and his direct awareness of it without the use of ISP subpoenas, somehow no lawsuits were deemed necessary, although Bronfman said that his kids had "suffered the consequences"

You know, this is the sort of hypocrisy that makes the RIAA in general, and Bronfman in particular, look like a complete tool.

This morning's keynote is from Heinz Roggenkamper, VP of Development at SAP Labs. His team does R&D at SAP, as a way of introducing the rest of SAP to possible futures. They've been looking at Cincom Smalltalk as one of those possibilities.

A Smalltalk test was done using a duplicate invoice finder problem as a test. They were pleasantly surprised at how quickly they got to a working proof of concept with help from Heeg. Those three weeks included a one week training class. One of the big take aways for them was that they felt like they understood the domain better at the end of the process.

They did a second proof of concept in a project called xCarrier, which deals with supporting shipping management: selecting the carrier, etc. They implemented an awful lot of the rule engine in 3 weeks, and got the proof of concept integrated with ABAP and Java components (web services). Georg Heeg picked up at this point to explain how things went from the Smalltalk side:

The approach taken was the classic one - model the known domain, and learn the rest of it as you go. This involved very short iterations with constant feedback. For the integration piece, a connection between Cincom Smalltalk and SAP NetWeaver (SAP's Web Services piece) was built by Heeg's team.

What does SAP like? They like the fast feedback from customers, and the ability to build executable case studies. Right now, they are using Smalltalk as a learning/exploratory tool rather than as a deployment tool.

Up next are Ralf Ehret of SAP, and Taylan Kraus-Wipperman of Heeg, talking about the Smalltalk to NetWeaver connection project.

What does this enable?

• SAP can use Smalltalk for exploratory modeling
• SAP customers can use Smalltalk with SAP
• Provides a standard way of integrating Smalltalk and SAP in a project

This provides a connection to all SAP back end services, and is a first step to being a part of the SAP Enterprise Service Architecture [ed: maybe the enterprisey types will notice :) ].

This is all built on the industry standard WSDL/SOAP model. This allows Smalltalk to invoke RFC-enabled modules. The NetWeaver Connection makes Smalltalk a first class citizen inside the SAP NetWeaver world - it allows anyone to use Smalltalk with or instead of Java and ABAP.

The Smalltalk side is built on top of the WS* stack on VW. With that, it's a demo of the xCarrier project, using the SAP order system and the VW Transportation Zone system (the VW piece of the xCarrier project). The steps:

• Process incoming order
• Find business partner
• Get TPZ for incoming order
• Use TPZ for truck load planning

The demo shows an SAP application talking to VW via the WS* stack - you can see a similar thing in one of the screencasts I did recently. This stuff is going to be available (beta) with VisualWorks 7.5. There's future development going on: deeper access to the SAP BAPI repository, automatic access to RFC function definitions, and access to the Enterprise Service Repository.

After a few interesting hiccups with his slides, Alan proceeded to talk about Store futures:

The topics: Shadow Compilation, updated Merge Tool, Glorp as a Store back end, Projects and Streams, and Internationalization (for Store).

Shadow Compiling: motivated by partial code loading - i.e., errors that occur while the code is loading from Store. Source loading involves filing in code from the repository, which can lead to file-in load ordering issues. For instance: you are loading a new version of the Oracle Database Connect while using the Oracle Database Connect as your repository connection.

Parcels obviate these issues by installing code after all the code has been read. Parcels also supports the loading of code that cannot be fully installed (but will be if/when the pre-requisites for it are loaded). Store loading works in one of two ways: Source (like file-in), Binary (like parcel loading). Source loading does handle unloadable definitions better than filing in. Binary loading does not.

So Shadow Compilation: like file-in, compiles source. Like binary, defers installation (loads into a shadow namespace). From the user's point of view, it's an atomic load. This stuff will be included in 7.5, but will not be turned on by default. It's essentially preview (beta). To turn it on:

Store.Bundle useShadowLoader: true.

There will be an option in settings for that.

This next part is mostly demo, of the new merge tool that's been done. It's a much nicer tool now - you'll just have to look at it when 7.5 ships.

Store For Glorp: a Glorp back end for Store. It adds an actual object model to Store. In the process it improves performance, makes for better queries, and supports schema modifications (at present, this is hard). This is in preview now, but a number of people are using it (including Cincom engineers). Features:

• Replication/Auti-Replication
• Publish
• Load
• Compare
• Merge
• Repository Crawler
• Browse Class Versions
• Store Worksbook - a workspace of useful Store expressions
• Auto-reconcile

Projects and Streams: Addresses "configuration management" issues in Store. Very early stage, design level work. We do want feedback.

Projects:

• Higher level code organization
• Tools aspect of that
• Code management aspect of that

We want projects to be partially loadable, aware of deployment and non-Smalltalk artifacts. We also want to support explicit branching. Streams more or less means a series of versions with branching supported. To do that now, you have to go by naming convention. Streams will allow something akin to Envy "open editions".

This is Dr. Jochen Eckert of DB Systems, who's going to tell us about train scheduling using Cincom Smalltalk:

The goal of this project: They needed to accurately schedule their trains with correct times, and without conflicting train paths. They have 40,000 trains/day, over 35,000 km of tracks. They needed:

• a GUI for Visualization and user interaction
• Detailed calculation of running times. times of usage, conflicts
• Multi-user access - 7 regional business units, around 50 users per unit.

The client is a VW 7.4.1 "fat client" connected to an Oracle 9 DB and some Smalltalk servers. There's also a lighter weight version for notebooks that uses personal Oracle.

Next up: Martin Kobetic, who's going to talk about the security frameworks in Cincom Smalltalk:

This talk will be covering SSL, client authentication, and certificates in Cincom Smalltalk. The web server being used for demonstration is a simple web server implemented in Opentalk. To use a secure connection, the first thing we need is a certificate. Typically, you get a certificate from a trusted source, but you can create them from code (probably for testing), or import one that has been issued:

You can save (and restore) keys that you generate for this to and from disk (or a database, etc). You can save and restore certificates the same way (in fact, I've done that in BottomFeeder). So with that out of the way, Martin is creating a secure (https) server. This looks just like creating a normal one, but with the additional step of handing it a certificate, and telling it to use a transport of https instead if http. With that done, using Firefox, we get the normal "Do you trust this certificate" prompt from the browser.

Unlike browsers, we don't ship CST with pre-trusted certificates. The reason? It's a hard job to make sure that the ones you ship are up to date and valid. You can add certificates to the registry (and save that to disk) pretty easily:

registry := X509Registry new.
registry addTrusted: someCertificate.

Likewise, there's protocol to handle revoking and removal of certificates. Also, you can export the certificates out of the browser and read them in using class CertificateFileReader.

Uwe Liebold of AMD is here to talk about testing frameworks that they use in their Smalltalk applications:

The CEI application is part of their APM (Automated Precision Manufacturing) approach. The APM powered fabs are controlled by software/hardware that Uwe calls their "central nervous system". The CEI baseline began with Fab 25 in Austin, Texas in the early 90's. It's been extended, enhanced over time. Currently, they are using VisualWorks 7.2. They have:

• ~3000 classes
• ~45,000 methods
• 27 MB runtime image

They have gotten more and more interested in testing as time has gone by - they simply cannot afford downtime in a 24x7 manufacturing system. At the same time, they have continuously changing requirements, so implementation and integration are never done. They started to get more serious about unit testing after they migrated up from VW 5i.4.

They've put testing on an equal footing with development - they now run all their tests after every integration, and they use SUnit both in development and in deployment (using RuntimeTestRunner, a tool that logs results rather than reporting to a GUI). They've introduced a concept called Matric Tests, which is based on hardware test scenarios. It's a 4 step process:

1. Set parameter(s)
2. Run component
3. Read result
4. Validate result

He's wrapping up with a demo - the TestMatrix stuff is kicked off the same way that normal SUnits are - using the browser extensions, straight from the RB.

In last Sunday's podcast, Peter Fisk mentioned that MS had released WPF/E for the Mac. Here's the link:

“WPF/E” (codename) is a browser enhancement module that enables browsers to render rich content in addition to HTML. ‘WPF/E” is compatible with both the Safari browser and Firefox 1.5.0.8 on MacOSX 10.4.8. The Dec 2006 CTP will expire on February 18, 2007 at which point when a web page that uses it is rendered, it will prompt the user to update to the latest version. “WPF/E” (codename) will periodically ping Microsoft.com to verify its integrity (at which point the only information that will be communicated will be your IP address and the module version).

So there you go - it looks like Vista Smalltalk won't be just for Vista...

Alan's going to cover some advanced ideas using Glorp - for instance, how can you use Glorp to do what Ruby on Rails /ActiveRecord does. Glorp itself is an open source (LGPL, with Smalltalk qualifications) that works across Smalltalk platforms. It's also the O/R future for Cincom Smalltalk. Glorp is meta-data driven.

So to basically define Rails - "opinionated software":

• Go really fast, in one direction
• Reaction against J2EE/.NET
• "Greenfield" projects
• Ruby based
• Some Smalltalk like "tricks" in RoR
• ActiveRecord pattern for persistence

To contrast: Glorp uses explicit metadata, while ActiveRecord is implicit. It uses strict naming conventions, hints at the class level, and is aware of (English) language forms. It does code generation (mostly for the web).

Glorp uses a single broker (session). It's responsible for object identity and manages automatic writes. It's agnostic to use (GUI, web, etc). Rails is actively for the web, classes act as brokers, there's no object identity, only one global session. Glorp puts a premium on flexibility, while Rails puts a premium on simplicity - there may not even be a domain model (per se).

So the question is, can we provide some of the benefits of Rails without losing our advantages?

• Automatic persistence
• convention driven
• but be less restrictive
• use a bit more information
• allow a graceful transition to non-automated

So first, we have to be able to read the DB schema - Glorp can now do that (at least, for Oracle and PostgreSQL). After a bit of explanation of how the schema is read, it's off to a demo. The demo hooks up one of the standard Seaside demos (the Sushi Store) to use a database instead of in-image data.

Martin is back up to talk about the WS* stack in VW. This is mostly a demonstration of the WS* tools that have been appearing in the product over the last few releases. The first demo is actually something I covered here, in one of my screencasts. Martin's next demo is exposing a Smalltalk service via WS*, and the example is a time service - which I posted on awhile back.

Finally, Martin demonstrated the new support for SOAP headers, both in the stack and the supporting wizards.

The NY Times reports that spam has simply exploded over the last year (especially the last few months):

You’re not the only one. Spam is back -- in e-mail in-boxes and on everyone’s minds. In the last six months, the problem has gotten measurably worse. Worldwide spam volumes have doubled from last year, according to Ironport, a spam filtering firm, and unsolicited junk mail now accounts for more than 9 of every 10 e-mail messages sent over the Internet.

That kind of volume is going to kill free email. I'm not sure how a paid system would push itself onto the net, but I would bet that a paid (and open only to members) service by a large vendor would attract interest.

Next we have 4 short presentations. First, Andre Schnoor of Cognitone:

Cognitone sells products that enable music prototyping. The editing allowed is pretty cool. Andre claims that he has saved 75% of the time he would have taken using anything else.

Next up: Jan Lukes, who's going to talk about using Store in a more Envy-like fashion:

What he's trying to get:

• Auto-publish
• Versions for classes
• Tool like ApplicationManager
• Better comparison tools
• Color coding for versions

They decided not to muck with Store itself, just the tool level interface to it. For auto-publish, they issue a sub-versioning publish on each accept. For class versions, they use one package per class, and hide packages completely. They treat Bundles more like Envy applications.

Next: Alfred Wullschleger - he's going to present a dynamically defined state model that's not based on the state pattern:

What they were after was a user configurable state model, so they created a state model that works a little like an event model.

And finally, Uwe Danzeglocke is going to talk about deploying cross platform software:

He also went briefly over some IT best practices standards and configuration management best practices. Interestingly, they base all of their products on one image, and control what can and cannot run based on license keys that unlock modules. They support one look and feel across the products, and have multi-lingual support.

One of the limitations for building web 2.0 apps: have to use existing (legacy, even) browser technology (i.e., what IE 6 can do). So we have XHTML, CSS 2.0, RSS, XML, HTTP, and Javascript. None of these are new - they are all mature technologies. So instead of a "big bang" of new stuff, we have a series of "small bangs".

So to Seaside: one major thing is that we have no templating. It's all done in Smalltalk. The metaphor is canvas and brushes.

Most of the presentation is a Seaside demo, which - without shooting video - I can't really convey well here. Michel concentrated on covering Seaside support for CSS, XHTML, and Javascript. On the latter, it uses the standard Scriptaculous libraries. One of the nicer things is that you write the actions in Smalltalk, and the Javascript gets created for you - you stay in Smalltalk at all times.

Another nice thing is that most debugging is in Smalltalk, using the Smalltalk debugger. Michel recommends using Firefox with the Firebug plugin at the browser level.

I couldn't take notes during Scott's talk - my machine was busy recording the talk. Scott introduced us to the open UP process that he's championing at IBM, which you can get information on here.

Peter Fisk is doing what Smalltalk did back in the early 90's: getting out in front of the bigger players by being more nimble:

Over the past couple of weeks, I have been focused on building an integrated GUI designer for Vista Smalltalk. The most difficult parts are now completed and I expect that a functioning tool for building simple user interfaces will be available before Christmas.

I think Peter's work bears watching.

This post on Java Generics is as good an example as any for why dynamic typing is just better. The sorts of edge cases and issues being debated simply don't come up for Smalltalkers.

If it walks like a duck, and quacks like a duck... you don't really need the compiler to tell you it's a duck.

It turns out that the artists don't really need more money from the public: just the studios:

Sure, the RIAA hasn't exactly been on the good side of the general public since, oh, this century began, but it sure isn't doing itself any favors with this latest hint of persuasion. While the agency has fought grandmothers, children, and cash-strapped citizens quite vigorously to "ensure artists are getting due payment," it has seemingly opened up a chink in its own armor by pleading with judges to "lower artist royalties."

Maybe Bronfman needs to buy a new house or something, now that he's given his own kids a "good talking to" about piracy.

Craig Latta got a spread in this week's SD Times - with an article about how he produces music with Smalltalk:

Most concertgoers are used to seeing large projection screens behind the performers. Trippy or poignant visuals are a standard part of any major musical performance these days. But when Craig Latta performs his extemporaneous pieces in front of an audience, the screens behind him project source code.

These musical performances don’t come from a set list, and his visual performances aren’t just precooked movie clippings or looped mandalas. Latta, instead, improvises the creation of both his musical and visual presentations. His instrument is the keyboard, and his music staff is accessed via Smalltalk.

I just love this kind of article - it shows up from time to time in a mainstream media production - probably in order to reassure the author that he's still relevant. This week's entry in the "columnists are soooo much better than bloggers" sweepstakes is Andrew Binstock, a man I've written about before - often enough that it's more useful to provide this google search than to point at individual posts. Suffice to say, Binstock has a casual relationship with the concept of research. Having gotten that out of the way, let's move along to this week's dreck:

You can quickly come to 90 percent of content if you add up the self-absorbed blogs of tweens, teens and college kids; the hate blogs; and, of course, the many, many abandoned blogs. Of the remaining 10 percent, you then eliminate topics that don’t interest you. You now are way under 1 percent -- yet you have literally hundreds of blogs to choose from. If software development is your thing, you’ll want to skim off the blogs by engineers or CEOs who are shills for their companies; those who evangelize their pet technology; and most especially, those who are always attacking or condemning some person, some company or some technology. Finally, you’re in the clear, with the handful of truly useful blogs.

Maybe, just maybe, Binstock has heard of this recommendation notion; i.e., "if I like this guy's writing, perhaps I'd also like this other guy he seems to like". Nahh, that would require research, and he's just allergic to that. Far better to spin out a few hundred words, collect the check from corporate, and keep stumbling cluelessly along.

The funny thing is, his entire article could just as easily refer to media (online and offline) in general. Ever been in a suburban hotel that's away from most things, where the only place you can find to get a magazine is the local quick mart? After you eliminate the porn and the celebrity rags, there's not a lot left.

Here's the talk given by Andreas Hiltner of Cincom, and Georg Heeg of Heeg on ObjectStudio 8. It's just under an hour, and provides an overview of the ObjectStudio 8 product.

The pile of audio to be editing wasn't enough, so Michael, David, and I recorded a podcast last night. We spoke about the OS 8 project - actually, more on the idea of embedding some other language into VW in a similar fashion. That carried us back to IBM's VisualAge product line, and we sallied forth from there. I'm editing the audio now, and will have that and the jobs report ready later today.

Nick Carr, and the NY Times' Jon Pareles (who he quotes, below) don't like the new, more open media environment:

When it comes to producing and, equally important, filtering and packaging creative work, the masses seem every bit as crass and conservative as the corporate overlords they're said to be replacing. Maybe more so, in fact. As Pareles writes:

The open question is whether those new, quirky, homemade filters will find better art than the old, crassly commercial ones. The most-played songs from unsigned bands on MySpace -- some played two million or three million times -- tend to be as sappy as anything on the radio; the most-viewed videos on YouTube are novelty bits, and proudly dorky. Mouse-clicking individuals can be as tasteless, in the aggregate, as entertainment professionals.

There's a phrase the two of them should read until it sinks in: One man's trash is another man's treasure. Supposedly "sappy" music is fairly harmless - why do they care? If the market enjoys music these guys don't like, it's no skin off anyone's nose. How many years has Hollywood been promoting utter dreck through the Oscars, while the rest of us go off to see movies that actually entertain us? Sometimes, escapism is all you really want.

Michael, David and I spoke late last night, on a variety of topics. We started out on modeling languages in Smalltalk (kicked off by this session from the Users Conference). From there, we ended up in a general discussion of the issues surrounding software sales.

There's going to be a break in production of Smalltalk Daily - or, if I do get to it, it will be later in the day. I have a lot of audio from the conference to deal with, and I'll be plowing through that for the next little while.

Jeff Jarvis throws out some thoughts on what internet media is and isn't - and how it relates to classic journalism. Like Jeff, I'm not sure that the old rules apply real well to this medium - it's a work in progress either way.

There's still too much hiss under Niall's talk, but you can hear the whole thing. In this session, Niall discussed strategies for porting a running system from one version (or dialect) of Smalltalk to another, while still making changes to the old stuff.

Nick Carr is suggesting that the music studios may be close to that "when all else fails, try some actual thought" moment:

Last week, I noted a Wall Street Journal article describing how online sales of digital music appear to be flattening this year. Because those sales are dominated by Apple's iTunes store, the numbers suggested that music companies would be under increasing pressure to seek strong new outlets for online sales, which would in turn likely require the sale of songs in unprotected MP3 format - in other words, without copy protection.

I predict another year or two of raw stupidity, partially propped up by the hope of device royalties (thank you, clueless chowderheads at Microsoft).

Hmm. It looks like Jason Pontin, who interviewed Bjarne Stroustrup recently, spent some time in a reality distortion field to prepare:

C++ remains the archetypal "high level" computer language (that is, one that preserves the features of natural, human language), and it is still used by millions of programmers. Many of the systems and applications of the PC and Internet eras were written in C++. For all that, the language remains controversial, largely because it is notoriously difficult to learn and use, and also because Stroustrup's design allows developers to make serious programming mistakes in the interest of preserving their freedom.

I might describe C++ in a lot of ways, but comparing it to "natural, human language" wouldn't be one of them. Stroustrup's comments in the interview are worth reading, but boy - the interviewer is living somewhere else. I wonder what color the sky is there?

Andrew McNeil, our man in Australia, has forwarded me this:

Due to public demand and the presence of a quorum there will be a xmas edition of the Sydney Smalltalk Users Group at the James Squire at Kings Street Wharf down at Darling Harbour.

Look forward to seeing everybody there.

Cees has a long post up comparing Smalltalk and Java - from the standpoint of a Smalltalker who has now spent a significant amount of time in Java. It's a long post, with fair critiques of both languages - well worth reading the whole thing. Here's the point I wanted to bring out, which I think is very important:

Ok, first what I miss - I dearly miss the image and the fact that a Smalltalk system is just always “there”, alive and waiting for your next command. In Eclipse, you will not find “Inspect” or “Debug” menu items in your pop-up, and I don’t think they are likely to ever appear. Although… Eclipse is already closer to a Smalltalk IDE than what I ever thought possible 5 years ago, so I’m not betting on it . But the system not always being alive is the biggest thing I miss - it hurts even more than the whole static typing thing.

There are a lot of benefits to having an image, and most people just don't even know what they are missing.

Here's the last session from Day one of the conference. Andreas Hiltner and Mark Grinnell went over the major differences between ObjectStudio classic and ObjectStudio 8, and what steps developers will need to take in moving to OS 8. This one is just under 39 minutes, and the noise levels aren't quite as bad as they were in the posts I put up over the weekend.

Technorati Tags: cincom smalltalk, objectstudio, smalltalk, users conference

I had time to put together a Smalltalk Daily today - this is Smalltalk to Smalltalk Opentalk, using ObjectStudio to VisualWorks - and Windows to Mac. I'll be plowing forward with this example for a few days.

In a response to Cees' post, this guy has the opposite viewpoint on "final":

One thing that made me go ‘whhueungh?!?’ is the conclusion that ‘final’ is a big mistake. I thoroughly don’t get this. Personal experience and generally accepted wisdom both agree that as a rule extending classes is a bad idea unless a class was designed for it in the first place. In fact, I litter ‘final’ statements all over the place. It mostly marks a class as: Don’t try and extend this! Just wrap it - to any developers that come after me. This works out fine. Where there is a generic element to extract (e.g. The functionality conveyed by java.util.Collection and java.util.Set where a HashSet is concerned) there’s usually an interface which gives you the option of wrapping. I wonder which classes he’s so bent on extending.

This assumes that any class is ever "done". I'd argue that such a beast simply doesn't exist, and that - as developers - we have absolutely no idea how the next guy down the pike who has to look atc our code is going to use it. We can guess, we can make assumptions - but that's about it. "Final" simply bakes in our assumptions, and gives that next guy the middle finger. Not with the intention of flipping him off, no - but flipping him off nevertheless.

Via Patrick Logan, I came across Stefan Tilkov's post quoting Peter Lacy:

As I see it the [WS-*] is so large and complex, and the participants so tightly coupled, that scaling to even enterprise levels is out of the question.... you will not be able to use this technology to build a fully distributed enterprise architecture. I am shocked. I mean there is so much evidence to the contrary. Er, isn't there?

You can bet that lots and lots of enterprisey types will go with WS* though, because of the soothing balm of WS-fuscation coming from all of the analysts they listen to (along with the herd behavior they cling to) - better to be wrong as a group than to be right as an individual. When your highest desire is to sit in "low information density" meetings so that you can get other work done, it's easy to fall for this kind of crap.

Nick Carr points out one of the interesting conundrums in the free software arena: mostly, free software helps the big vendors:

IBM and Yahoo are pulling a Google on Google. The duo has announced that they'll start giving away a basic version of IBM's OmniFind software for searching corporate documents, undercutting one of the few products that Google actually charges for. Aimed at smaller companies, the free software can index up to 500,000 documents. Running on a server, it uses a customizable, Yahoo-like browser interface and integrates Yahoo web search results. Google currently charges $9,000 for a specialized search appliance - a piece of hardware called Google Mini - that can index up to 300,000 documents. The IBM-Yahoo offering undermines the market viability of the Google box in its current form, or at least at its current price, and also poses a threat to the efforts of corporate search specialists like Autonomy to expand into the small-business market.

The question you want to ask is this: were the bigger vendors generous with (hardware) license costs back when they gave away software in the early days? What makes all the advocates of free software think that the rules are different now - companies like IBM are not doing this out of a sense of altruism.

In this keynote session from the 2006 Cincom Smalltalk Users Conference, Heinz Ulrich Roggenkemper explained how SAP Development Labs are exploring the use of Cincom Smalltalk. Georg Heeg spoke briefly to explain some of the help given by his organization to this effort.
