What's Going on With Xtreams-Grid?

August 20, 2011 19:32:34.374

I just spoke to Arden Thomas, the Product Manager for Cincom Smalltalk. here's what he told me: Xtreams continues to be open source software. The grid implementation, on the other hand, is not open source - it's "take two" on what Cincom has been calling Polycephaly.

There was apparently concern over the naming - using the Xtreams name would have developers presume that the software - like Xtreams itself - was open source.

That's the good news, as it were - the entire kerfuffle (mentioned here) is a misunderstanding. The bad news? The utter lack of communication from Cincom. Yes, Arden graciously spoke to me about this, but I'm sure that he doesn't want to make personal phone calls to every single person with a question about this sort of thing. When questions like this arise, there really ought to be some kind of statement, even if it only amounts to "we regret the confusion, we'll have more details out shortly". The vast well of silence approach leads to questions, and worse - leads to people coming up with their own answers.

Ultimately, this kind of thing is a management failure. I'm happy that Arden was willing to reach out to me on this, and he deserves kudos for that.

Update: Here's the kind of community behavior that they are creating - I saw this at the end of a VWNC mailing list post, where someone was trying to explain how to solve a problem:

I'm not sure what the rules are on posting the code, and so I'm just providing the references.

When people are thinking that way, it's not a good thing.

A Good Question About Xtreams

August 20, 2011 12:24:36.078

I saw this (that link will pass through a small registration UI if you haven't visited the archives before, I think) pop up in the VWNC mailing list today:

WANTED for xtream coolness and usefulness: Xtreams-Grid The delinquent has last been seen on the 11th of July, when he disclosed his shocking crimes. He left his home and went into hiding shortly after. Every hint is appreciated. Please call 1-800-GRID or report here.

While it's amusing, it's also a good question. I saw the grid announcement as well, and then... nothing. I know it's not the developers of that code keeping it quiet on purpose; that's not their style. So it's a Cincom question. Anyone? Bueller?

Update: I spoke to Arden Thomas, CST Product Manager about this. Details here.

We Know Less About UI Design Than We Think We Do

August 20, 2011 12:14:08.448

It's easy to read an article like this one - which notes that the vast majority of people don't know that ctrl/command-F executes a search - and chuckle about our superiority. What it should do is makes us sit back and think, because it's clear that the "simple" UI's that are presented to people aren't as simple as we think they are. There's a reason that the touch interface pioneered by Apple with the iPod, iPhone, and iPad has caught on so well - it finally operates the way most people want a device to operate. There's a lesson in there somewhere.

Not Getting It

August 19, 2011 15:42:23.881

Thilo Weichart may not be the dumbest man on the planet, but he'd be up there in any competition. He's scared by the - wait for it - Facebook "like" button:

Weichert argues that data from any user who clicks the ‘like’ button including those who are not Facebook users (which seems to be the crux of the problem for Weichert) is immediately transmitted to a server in the United States. Weichert told German newspaper FAZ that his concern is that “Facebook can track every click on a site, how long I’m there, what I’m interested in.”

Here's a hot tip for this clown: try not clicking on the button. There, I fixed it.

Lost Investment

August 19, 2011 0:33:06.415

This is the sort of thing that really, really makes you wonder. First, HP dropped Windows for their tablets, bought Palm, and announced that WebOS was the future. Then they promoted the heck out of the TouchPad. Now... this:

In a dramatic turn of events, Hewlett-Packard said on Thursday that it will stop selling hardware based on the webOS it acquired from Palm. As part of its broad statement on Thursday regarding plans to consider spinning out its PC business, HP said “that it plans to announce that it will discontinue operations for webOS devices, specifically the TouchPad and webOS phones.”

That is one heck of a lot of wasted money...

The New CST Eval License

August 18, 2011 18:50:09.276

There are some curious things about the new license for the eval (not NC; they apparently changed things) version of VW and OS. I didn't look at the license carefully when installing (I know, but really - who does?). After seeing some discussion in the mailing list, I dug the license out of the product directory, and wow - it's a lot more restrictive than it used to be. Take this, for instance:

Licensor hereby grants to you, and you do hereby accept, a nonexclusive and nontransferable license to use the Product only as is authorized in this License Agreement. The Product may be used only at a single location on computers owned, leased or otherwise controlled by you in the manner and subject to the terms set forth in this License Agreement. You agree that you will not deploy, assign, sublicense, transfer, pledge, lease, rent, allow access to or share your rights under this License Agreement. You agree that your rights under this License Agreement do not cover deployment and are not to pass to a successor through merger or consolidation.

Technically speaking, you can't create a runtime image and deploy it even for personal, non-commercial use on one machine. That's kind of silly; I can accomplish the same thing by running a development image, so it's not clear to me who or what they think they are protecting here.

More importantly, this takes any and all community projects that might consider using VW or OS and just stops them dead. If you have been using the NC, the safest route is probably to stay with the latest version that was downloadable (7.7.1 if you grabbed it before they had it offline). As a curious side note, the old license is still the one they have on the website, which makes the whole thing even more confusing.

The amazing thing about this is that Smalltalk is already a niche product - the primary problem is that there aren't enough developers using it. How this encourages more people to grab it and give it a try is beyond me. Instantiations has the open source license path, if you are building open source applications - that leaves a door open to people who want to try something out using VA. Gemstone makes it even easier - you pay them for Gemstone/S when you hit a wall with the (CPU limited) version they have up for download.

Meanwhile, Cincom reminds me of the opening scene in "The Hitchhikers Guide to the Galaxy" - where the aliens remind humanity that the bypass plans have been locked in a basement on a distant planet for 50 years, and gosh, that should have been obvious enough.

Fun with Fuel

August 17, 2011 16:17:42.000

Mariano has some fun things to show off with Fuel at ESUG:

The first thing it come to my mind, was the following: debug something from the workspace and in the middle of the debugging, serialize the debugger into a file. Then open another image, materialize the debugger, and continue debugging. The good news is that it worked from the first shoot! Nice! I will show it in ESUG. Now, the second thing was something that was in my head since a couple of months: use Fuel to get a byte array representation of an object graph and store/retrieve it from a NoSQL database. Of course, there are several NoSQL databases, and even several wrappers for Pharo. For my experiments I choose Riak because I read it may have the best results. Runar Jordahl did the binding for such database and as many cases, the API is using HTTP protocol. Thanks to Sven Van Caekenberghe, we have now a wonderful HTTP library in Pharo Smalltalk: Zinc. Obviously, Riak client for Pharo uses Zinc.

Wish I could be at the conference or, failing that, that there was live streaming like last year :)

Registration Considered Harmful

August 17, 2011 14:24:08.124

Marketing departments spend a lot of time telling you how they need registration screens "for leads" (believe me - a lot of the arguments I had at Cincom centered around that topic). Meanwhile, out in the real world, here's what actually happens:

That's not a rhetorical question -- the answer is 45% of you will just bail out on the purchase, rather than give them an email address, wait for confirmation, click on the confirmation email, etc. When one "unnamed company" decided to finally get rid of that annoying piece of s*** and just let customers shop in peace, they found an extra $300,000,000 in sales by the end of the year. In the first month alone, they generated an additional $15,000,000.

But trust your marketing department - those "leads" are "priceless".

ST 4U 121: Adding a Post Editor

August 17, 2011 9:27:15.791

Today's Smalltalk 4 You continues the VA Smalltalk Seaside tutorial with a posting tool. That gets us into flow control using #show:onAnswer:, as we need to know whether a post was submitted or cancelled on the new form we'll create today. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube. To watch now, click on the image below:

Seaside Flow.

If you have trouble viewing that directly, you can click here to download the video directly. If you need the video in a Windows Media format, then download that here.

You can also watch it on YouTube:


Today we'll start making use of the login UI and custom session by creating a posting tool for the blog server. We'll be following the same pattern of development we did for the Login UI; that also means that we'll be looking at #show:onAnswer: in more depth today. Last time we used it in more or less the simplest case (i.e., we threw away the answer). Today we'll be doing more normal application flow control. To get started, define a new subclass of WAComponent:


WAComponent subclass: #BlogPostView
	instanceVariableNames: 'post'
	classVariableNames: ''
	poolDictionaries: ''

Next, we need to define a new component that will be used to login - BlogLoginView. This will be a second entry point into the application, but only for authorized users. Today, we'll be setting it and the custom session up:


WAComponent subclass: #BlogLoginView
	instanceVariableNames: 'user'
	classVariableNames: ''
	poolDictionaries: ''

We'll need to initialize any new instances of the post tool - we want them to hold an instance of BlogPost:


initialize
	"Initialize a newly created instance. This method must answer the receiver."

	super initialize.
	post := BlogPost new.

The control flow we'll set up with rendering will be a lot like the login UI< but we'll have to pay attention to the answer value this time:


renderContentOn: html
	html form: [
		html table: [
			html
				tableRow: [self renderTitleFieldOn: html];
				tableRow: [self renderContentFieldOn: html];
				tableRow: [self renderOwnerFieldOn: html];
				tableRow: [self renderButtonsOn: html]]]

renderTitleFieldOn: html
	html
		tableData: [html text: 'Title: '];
		tableData: [html textInput on: #title of: self post]

renderContentFieldOn: html
	html
		tableData: [html text: 'Content: '];
		tableData: [html textArea on: #content of: self post]

renderOwnerFieldOn: html
	html
		tableData: [html text: 'Owner: '];
		tableData: [html textInput on: #owner of: self post]

renderButtonsOn: html
	html
		tableData;
		tableData:
			[html submitButton
				callback: [self answer: true];
				value: 'Save'.
			html submitButton
				callback: [self answer: false];
				value: 'Cancel']


Notice how we send back an answer object (a boolean) in the callbacks. That makes the post tool operate a lot like a UI dialog with an accept and button. The real action kicks off from our main UI in BlogServerView. If we have a user in the session (i.e., we came in via the login UI), then we display a new menu option:


initializeMenuComponent
	menuComponent := BlogMenuView new.
	self session currentUser ifNotNil: [menuComponent addEntry: 'New Post' withAction: [self addPost]].
	menuComponent addEntry: 'All Posts' withAction: [self allPosts].
	menuComponent addEntry: 'Today''s Posts' withAction: [self todaysPosts].

The action for this link is #addPost - here's that method:


addPost
	| editor |
	editor := BlogPostView new.
	self show: editor onAnswer: [:ans | 
		ans 
			ifTrue: [BlogStorage default posts addFirst: editor post].
		self show: BlogServerView new onAnswer: [:ans2 | ]]

This is where we make use of the non-continuation control flow. We use #show:onAnswer: to move to the post tool, and we provide an answer block that examines the answer. On true, it saves the post. We don't worry about false, because either way, we proceed back to the main post view. That's all there is to flow control in Seaside when you aren't using Continuations. In many respects, it's a lot simpler.

Let's take a look at how the changes operate. First, this is the main view when we didn't login. Notice the lack of the posting option:

Main View

Now we'll go to the login UI and login:

Login

That takes us back to the main view, but now we show our new posting option:

Posting Option

Follow that link:

Post Tool

Now add the post and save it - you should see something like this:

New Post

That's it for today - but we've now seen how flow control works when using Seaside in VA Smalltalk.

Upgrading From 7.6 to 7.8

August 15, 2011 15:58:35.148

I started a serious look at upgrading our codebase from VW 7.6 to VW 7.8 today (at least, until the next crisis appears on the horizon). The first thing I did was locate this workspace script I created late last year:


"report to a file"
file := 'mesOverrideReport.txt' asFilename writeStream.
file nextPutAll: 'For VW 7.6 with MES Loaded'; cr; cr.

"find all the overridden classes"
overriddenClasses := SmalltalkWorkbench sortedClasses select: [:each | Override isOverriddenClassOrNameSpace: each].

overriddenClasses do: [:each |
	file nextPutAll: each fullName	asString.
	file cr; tab.
	file nextPutAll: each instVarNames printString.
	file tab.
	file nextPutAll: each instVarNames size printString.
	file cr; cr].
file close.

Once I had that, I created a little class that imported that data, massaged it a bit, and then grabbed the equivalent data for the 7.8 classes (I had to load a few packages to get all of that to happen. The crux of my check was to ask the objects I created this question - if the 7.6 class had more instance variables, but they otherwise matched (or vice versa for the 7.8 class), then loading the class definitions (remember, these are overrides of class definitions) would be smooth. Doing that reduced my problem space from 29 classes down to 7, and a quick manual check of those reduced it to 2. One of those was obsoleted in 7.8 (per the release notes), so I can either change the code, or just load in our (now obsolete) override.

That left me with one class where the shape had changed in a reall incompatible way, and that will entail going back to 7.6 and changing the class definition. I'll then push that into my local repository (I created a SQLLite Store to manage the tons of useless intermediate versions I'll create). That should let me at least load the code into 7.8. Lots of things will be broken, of course - there are all the method overrides to deal with. Half the battle is getting the code to load though, and I'm most of the way there now.

ST 4U 120: Flow in a VA Seaside App

August 15, 2011 9:49:21.910

Today's Smalltalk 4 You continues the VA Smalltalk Seaside tutorial with a closer look at the Login UI we created last time. In VA, we don't have full continuaton support, so the stock #call: usage you might normally see doesn't work - instead, we use #show:onAnswer:. That' a standard part of Seaside, but it behaves a bit differently. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube. To watch now, click on the image below:

Seaside Flow.

If you have trouble viewing that directly, you can click here to download the video directly. If you need the video in a Windows Media format, then download that here.

You can also watch it on YouTube:


In this section we'll add the login UI for our posting tool (not written yet), and start making use of the custom session we set up last time. Next time, we'll get to the posting interface. One of the main things we'll look at today is how Seaside in VA differs a bit from Seaside in other Smalltalks - the lack of support for full continuations (meaning, you can't use #call:). In fact, if you try to use #call:, you'll get an exception (which can make following other tutorials a bit rough at times). As it happens, the lack of full continuation support in VA isn't much an issue with the current version of Seaside - which well see in a moment.

First, let's define the BlogLoginView class:


WAComponent subclass: #BlogLoginView
    instanceVariableNames: 'user '
    classVariableNames: ''
    poolDictionaries: ''

Note the user variable - we'll be checking that against the registered users (set up with workspace code in our example). That means we need to initialize that:


initialize
	"holds current user"

	super initialize.
	user := BlogUser new

Next, we'll render the form, and see how things differ a bit without #call::


renderContentOn: html
	html div
		class: 'login';
		with: [html paragraph: [html strong: [html text: 'Login to Post/Edit']].
				html form: [html table: [html tableRow: [self renderUsernameOn: html].
							html tableRow: [self renderPasswordOn: html]].
						self renderButtonsOn: html]]

renderUsernameOn: html
	html
		tableData: [html text: 'Username: '];
		tableData: [html textInput on: #username of: self user].

renderPasswordOn: html
	html
		tableData: [html text: 'Password: '];
		tableData: [html passwordInput on: #password of: self user].

renderButtonsOn: html
	html div with: 
		[html submitButton
			callback: [self validateLogin];
			value: 'Login'.
		html submitButton
			callback: [self show: BlogServerView new onAnswer: [:ans | ans]];
			value: 'cancel']

validateLogin
	| userOrNil |
	userOrNil := BlogStorage default users
		detect: [:each | each username = self user username and: [each password = self user password]]
		ifNone: [nil].
	self session currentUser: userOrNil.
	self show: BlogServerView new onAnswer: [:ans | ans]

There are a few things going on here worth noticing. First, see how we store data in Seaside forms? Using a symbol and a reference to the object, we map directly. That makes form handling in Seaside much, much easier than it is in many other web frameworks. Next, look at the password method above - note how easy it is to hide the password. Finally, in #renderButtonsOn: and #validateLogin, note the use of #show:onAnswer: rather than #call:

When using a continuation (#call:), control passes to the new component, and then the code returns to the point of the #call: when that component yields control. Using #show:onAnswer:, we don't get that behavior - instead, control passes to the block (the second argument) when the new component yields control. The end result is much the same, so Seaside operates as it normally does - but you do end up with less memory overhead due to fewer context stacks lurking in memory. The upshot at this point is this: use this pattern when developing Seaside apps in VA. You don't have to limit it to VA though; #show:onAnswer: is fully portable.

That about wraps it up for today - next time, we'll get into the posting tool itself.

Need more help? There's a screencast for other topics like this which you may want to watch. Questions? Try the "Chat with James" Google gadget over in the sidebar.

Smalltalk Harbour Reaches First Version Milestone

August 14, 2011 18:56:32.123

I saw this on the ESUG mailing list:

We are pleased to announce the first version of SmallHarbour.

SmallHarbour is a public fork of SeasideHosting, running on top of Pharo, Seaside and Cog - driven by Romain Verduci and Laurent Laffont for ESUG SummerTalk 2011.

The main goals are:

  • people should be able to (easily) setup their own web application deployment platform
  • provide a public service for hosting web applications.
  • be able to setup a web application without Smalltalk knowledge in one click.

Actually SmallHarbour support Pharo and Seaside, but we expect to support Iliad and AidaWeb framework soon.

Stephanne Ducasse will be giving a free "Intro to Smalltalk" lecture before ESUG 2011 opens at the site Saturday, August 20:

Discovering Smalltalk Smalltalk is a pure and elegant object language. This lectures will cover the fundamental aspects of Smalltalk: syntax, semantics, and key aspects of the system. Doing so we will also revise the real semantics of self/super. We will show the power of polymorphism in action by simply learning from the system. Finally we will go into more design aspect again based on the systems. As a bonus we will start the lecture with a 15 min presentation of Seaside a powerful web framework for dynamic web application.
This lecture may be followed by a lecture on more advanced object-oriented design: law of demeter, encapsulation, multiple interface of classes, composition vs. inheritance

tODE runs as a javascript client in the web-browser and leverages the hypertext model to provide a natural and powerful tool for manipulating and exploring objects in the Smalltalk image. tODE has mappings for all of the traditional Smalltalk tools (inspectors, browsers, debuggers) and some unique tools in support of multi-platform development. tODE is currently in a pre-alpha development state and version 0.1 is in a near constant state of flux. If you want to take tODE for a spin, download the One-Click image.

There are instructions on the Google code site for loading it from scratch, and a "getting started" video. Sounds pretty cool; I'll have to check it out.
