Smalltalk Tidbits, Industry Rants

Steve Yegge gave a dynamic language talk recently, and I have to comment on this from the Q&A segment:

Q: These great things that IDEs have, what's gonna change there, like what's gonna really help?
Well, I think the biggest thing about IDEs is... first of all, dynamic languages will catch up, in terms of sort of having feature parity. The other thing is that IDEs are increasingly going to tie themselves to the running program. Right? Because they're already kind of doing it, but it's kind of half-assed, and it's because they still have this notion of static vs. dynamic, compile-time vs. run-time, and these are... really, it's a continuum. It really is. You know, I mean, because you can invoke the compiler at run time.

Hmm - that sounds a lot like what Smalltalk has done for, I don't know, 3 decades now :)

You could have a look at this video to see what I mean.

Randal Schwartz gave a Seaside talk at MySpace recently, to a pretty engaged audience, sounds like. He has his presentation at the link. One correction: Cincom does not use Envy - but we ship Store for version control with the product. We'll have more to say about how that's integrated with Web Velocity soon :)

This from John Dvorak is probably the best summation I've seen of fair use and copyright:

All we are seeing with YouTube clips is a modern version of a quote or excerpt. That's all it is. It's not piracy. It's not stealing. It's not a threat to any income stream. There is no net loss to anyone except the host paying for the bandwidth. It's fair use. Let's not forget how important the notion of fair use is. And don't let bullies like Redstone tell you otherwise.

Exactly.

Smalltalk Solutions 2008 is coming up fast - the schedule of events is here, and registration is here. There are a ton of great talks, like this one from Petr Stepanek:

Craft.CASE is a business process management tool written entirely in VisualWorks. Its main goal is to help process analysts to analyze existing complex processes and process designers to design replacement processes in a way of creating a concise, compendious and consistent model. It helps most in cases of unclear and changing requirements. If the business processes are to be supported by a software product, Craft.CASE supports a UML notation for a conceptual model and maintains links between elements of processes and elements of conceptual model.

The Los Angeles Smalltalk Users Group is meeting on the 19th at 7pm - head on over here for details.

Spotted in Wired Top Stories:

Online stores are bereft of inventory, Apple says, a sure sign that stocks are being reduced ahead of the launch of the next-generation iPhone.

So is Apple pulling stock to heighten demand ahead of their June show, or are they actually sold out?

We've gotten lots of questions about Store (our version control system) over the last few years, and I thought it might be useful to ask a few questions:

• Do you use bundles?
• If so, how do you use them, and why?
• If setting explicit pre-reqs was easier, would you still use bundles?

I'd appreciate any feedback - you can email me, or leave a comment.

Update: Travis asks some better questions on the topic

Smalltalk Solutions 2008 is coming up fast - the schedule of events is here, and registration is here. There are a ton of great talks, like this keynote from Gilad Bracha:

The closer one looks at Smalltalk, the more one appreciates how exquisitely well designed it is. Just as Hoare said of Algol, Smalltalk too was " a language so far ahead of its time, that it was not only an improvement on its predecessors, but also on nearly all its successors". Nevertheless, Smalltalk has shortcomings, in particular with respect to modularity, security and its interplay with the dark world outside its borders.

Newspeak differs from Smalltalk in four key respects: it is purely message based, it treats classes as linguistic entities, it provides access control for methods, and it has no static state. We'll explain what all this means, how these features synergize to provide a powerful component module system and an object-cability security model, and how it leads to an attractive platform well suited to the internet age.

On today's Smalltalk Daily, we take a look at building a simple grammar in SmaCC, a Smalltalk compiler-compiler.

Blaine Buxton points out this great summation of OO:

In all other languages we've considered [Fortran, Algol60, Lisp, APL, Cobol, Pascal], a program consists of passive data-objects on the one hand and the executable program that manipulates these passive objects on the other. Object-oriented programs replace this bipartite structure with a homogeneous one: they consist of a set of data systems, each of which is capable of operating on itself.

- David Gelernter and Suresh J Jag

Like Blaine, I'm not at all sure why Paul Graham has so much trouble understanding the idea - it's just not that hard.

Travel information for the conference, in August

This week we have a pretty full podcast - we covered Sun's backstroke on close-sourcing parts of MySQL, the problems for ReiserFS with the guilty verdict for the developer, Knuth's interview where he dissed testing, mocks, and multi-threading - and a host of Smalltalk news, including Smalltalk Solutions and ESUG announcements.

In Smalltalk news, we talked about:

• Syx
• the Iron Smalltalk call
• ESUG 2008
• Smalltalk Solutions 2008
• Pharo
• Newspeak going open source
• Smalltalk parsing

If you have feedback, send it to smalltalkpodcasts@cincom.com - or visit us on iTunes, Facebook, or on Ning. You can also vote for us on Podcast Alley.

With the rise of Macs, this is the sort of old bug that matters: a 25 year old flaw in Samba for BSD. Makes me wonder how many other "oldies but goodies" are lurking in the codebase of BSD...

If you're interested in either Ruby or Smalltalk (or both!), and you're in the Raleigh NC area, I'll be speaking to the Ruby Brigade there on May 20:

An Introduction To Seaside

Seaside is an open source, cross-Smalltalk web application framework. Like Ruby on Rails, it is "opinionated software". Unlike Rails, it's fairly heretical in its approach to building stateful web applications. I'll introduce Seaside, cover some Smalltalk basics, and answer questions from the audience.

You can get the meeting details here.

Blaine Buxton will be presenting Seaside tomorrow in KC:

If you are in Kansas City tomorrow and want to learn more about Seaside, then come to BarCampKC. I will be giving a presentation on Seaside. It's the one you can download from SqueakMap, but beefed up. I've included how to do GLORP, script.aculo.us, and more! I will be showing off Smalltalk and Squeak in the process. If you ever wondered why Smalltalk was so cool, now is the time to find out. See you there!

Smalltalk Solutions 2008 is coming up fast - the schedule of events is here, and registration is here. There are a ton of great talks, like this tutorial from James Foster:

This hands-on tutorial will present Seaside and walk through the process of building an application using GLASS (GemStone, Linux, Apache, Seaside, and Smalltalk). Topics covered include handling user logins, where to put session data vs. application data, building reusable components, styling a web site with CSS, and an introduction to Javascript. In a few hours you will build a web site for a children's soccer team that tracks games, players, and other information. (Because we are using an object database, we will not cover object/relational mapping!) You may bring your own computer or team up with someone else who brought one. Participants with a 64-bit machine may wish to pre-install VMware Server (free for Linux or Windows) or VMware Fusion (for Macintosh) so they can use a ready-to-run virtual appliance. Otherwise, a server will be available that can be accessed with a Squeak-based client. While familiarity with Smalltalk is a prerequisite, no prior Seaside or GemStone/S knowledge is required and the Seaside knowledge gained will apply to non-GemStone platforms as well.

Today must be DRM day - here's the RIAA, convinced that we'd love DRM, if only we would give it a chance:

Not so fast, said Hughes, who predicted that DRM would reemerge in a big way. "I think there is going to be a shift," he told the audience. "I think there will be a movement towards subscription services and they will eventually mean the return of DRM."

Hughes also said that DRM must change so that the public sees it less as a sort of policeman that locks music a way. He would prefer a mode where consumers don't notice DRM at all. "People just want music when they want it," he said. "It's about access. If they get that then they don't care about DRM."

Yeah, there's a pleasant theory. Sadly, the whole PlaysForSure fiasco drills a rather huge whole in that sorry excuse for thinking. The public doesn't care about DRM - but they do care about having stuff they bought stop working.

The MPAA is even dumber:

Fritz Attaway, executive vice president at the Motion Picture Association of America (MPAA) said: "We need DRM to show our customers the limits of the license they have entered into with us."

Translation: "You're not customers, you're dirty rotten thieves"

Because my neighbor downloading an episode of "Bones" via Bittorrent is just as bad as running a crack house (this is in LA):

In an ordinance just adopted, the five-member board is declaring that piracy "substantially interferes with the interest of the public in the quality of life and community peace, lawful commerce in the county, property values, and is detrimental to the public health, safety, and welfare of the county's citizens, its businesses and its visitors."

Can someone send the Los Angeles County Board of Supervisors a thesaurus, with the phrase "sense of proportion" underlined?

And Microsoft may be developing a deep case of the stupids as well. Here's what it looks like they might allow NBC to get from the Zune store:

The second story is about NBC shows coming to the Microsoft Zune media player, but with one feature NBC wanted added to the device: the copyright cop. If you buy a NBC show and transfer it to your Zune, a small application will check your Zune for "pirated" shows and movies that weren't purchased from the Zune store, and delete them. It's rumored that this is why the NBC/Apple partnership ended at the iTMS and they removed shows -- because Apple refused to build in this kind of capability.

Yeah, that sure makes me want to run out and buy a Zune. I've ripped DVD's to my hard drive for the sole purpose of watching a movie while traveling (carrying the DVD and case is too much of a pain). In the (incredibly small) brain of Jeff Zucker, that's an action that gives him permission to erase the "offending" content after I get something from the Zune store. Umm, thanks, but no thanks.

In that NY Times story, MS states explicitly that they won't do that:

We have no plans or commitments to implement any new type of content filtering in the Zune devices as part of our content distribution deal with NBC.

That sounds good, but recall: this is the outfit that just told you to take a hike with "PlaysForSure". They shouldn't be surprised that out confidence level in them is low....

There's a live calendar for Smalltalk Solutions 2008 on the STIC home page now; it's written in Seaside, of course (the calendar, that is). I'll be tossing it on the cincomsmalltalk.com events page today as well.

On today's Smalltalk Daily, we take a look at Shared Variables - which are the successor to Class Variables in older versions of the product (and other Smalltalk implementations).

Smalltalk Solutions 2008 is coming up fast - the schedule of events is here, and registration is here. There are a ton of great talks, like this one from Randal Schwartz:

Now that Seaside is being established by ever-widening audiences as a flexible and practical web application framework, many are asking the question "but how do I save my data?". In this talk, I'll present and compare an overview of the various solutions for persistence in Seaside, including: saving the image regularly, image segments, Magma, GLORP, and emStone/S. Smalltalk knowledge is presumed, of course.

Randal is a well known developer in the Perl world who's come back to Smalltalk recently - because of Seaside. You can listen to Randal regularly on FLOSS Weekly

Here's a photo of the non-tech (i.e., business) side of the Cincom Smalltalk team - I'm not in it because - for personal reasons - I couldn't attend the meeting in person:

Smalltalk Solutions 2008 is coming up fast - the schedule of events is here, and registration is here. There are a ton of great talks, like this one from Vassili Bykov:

Programming environments are commonly built as sets of tools, where a tool has the shape of a pre-composed window displaying and manipulating a set of domain objects. This talk takes a critical look at that approach and presents Hopscotch, an application framework and development environment based on different concepts. Hopscotch is the IDE and the application framework of Newspeak, a new language and development platform inspired by Smalltalk and Self.

The MySQL buy just looks worse for Sun all the time. The uproar over closed source has apparently ended; they now say that all of the high end features will remain open. So much for the idea of making MySQL a profitable business for Sun; maybe Jonathan Schwartz can start rummaging through the couch cushions for spare change to make back that $1B ?

Here's a question I get asked from time to time - "Why Seaside?" As in, why not Rails, or some other web application framework? Well, it's all about Simplicity. Here's the "Getting Started" for RoR, that takes you to "Hello World". It's not bad - but compare it with Seaside:

• Subclass WAComponent (Call the class HelloWorld)
• Add a method that looks like this:

renderContentOn: html
	html text: 'hello World'.

And this method on the class side:

canBeRoot
	^true

• Execute this line of code: HelloWorld registerAsApplication: 'helloworld'

Now, using VW 7.6, browse this url: http://localhost:7777/seaside/helloworld

And that's all there is to it. Now, why not take a look at the tutorial?

Gilad Bracha has announced that Newspeak will be released under an open source license (Apache). It should be interesting to learn more at StS 2008.

Dave Buck is tossing around the idea of offering an advanced Smalltalk course:

I've been tossing around the idea of developing advanced Smalltalk courses and was wondering what interest there may be in them. They could be delivered as open enrollment courses or on-site courses.

I was supposed to be in Cincinnati this week, attending a meeting. I had a personal thing come up that made it impossible for me to travel this week, but I still wanted to be part of the meeting. Even without a lot of preparation, this is a lot easier than it used to be.

My colleague Arden is at the meeting with his Mac, and I have an iChat video session open on the room. This gives me a fairly decent feel for the meeting. At the same time, we have the audio for that muted and I have a skype out call going to get onto a speaker phone in the room.

That's all going by wired networking here, and wifi in the meeting room itself. THis is all pretty cool. The only downside? If I get up to get coffee, it's just as noticeable as if I were there in person :)

Looking to learn more about Smalltalk in Japanese? My colleague, Katsuya Ichiisi, has translated both the Smalltalk tutorial and the Seaside tutorial. Enjoy!
