Your Waiter, the iPad

April 22, 2011 17:53:02.269

Honestly, this is a level of disintermediation I hadn't really expected: tablets replacing a lot of waiter functions:

So what does the future of ordering food look like? The tablets allow you to browse the menu, and check out what your meal look like before you order. You can then share what you find with others at the table. Once you and your group find something that you like, the tablet relays your order directly to the kitchen.

Makes sense to me, and I'd expect this sort of thing to be used as a major cost saving measure in some of the bigger chains. High end places will still employ full service wait staff, but this sort of thing could take out the entire mid range.

ST 4U 73: Exploring VA Browsers

April 22, 2011 10:08:32.140

Today's Smalltalk 4 You takes an overview look at the browser set in VA Smalltalk (omitting the ENVY specific ones - we'll go through those in a separate tutorial). If you prefer a written walkthrough to video, then skip down to it. 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:

VA Browsers

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 take a look at some of the different kinds of browsers in VA Smalltalk, and what they are used for. This is an overview; we'll be going into more depth in other tutorials. Go to the launcher, and pull down the tools menu, and select Browse Classes

Class Browser

You should see something like this pop up:

Browse Class

That's the class browser; we'll put that aside and pull down the tools menu again, selecting Browse Senders. You'll get prompted for a selector; enter at:

Browsing Senders

This brings up a browser on all of the senders of the message #at: - there are a lot of them. Let's put that aside, and find all of the implementors of #at:

Browsing Senders

Let's push that aside and look for all of the implementors - pull down the tools menu again and select Browse Implementors:

Browsing Implementors

Enter at: again, and you should see this:

Browsing Senders

This browser looks a lot like the previous one, it's just focused on the implementations rather than the invocations. Let's move along to references - what if you want to find all of the places that a class, Global, or class variable are used? Pull down the tools menu again, and select Browse References. Enter something like Processor:

Browsing References

You'll get a browser that looks like this:

Browsing References

More often, you'll want to browse a specific class - pull down the tools menu again, and select Browse Class - I entered Collection:

Browse Class

Browse Class

There's another browsing option in VA that's not common in Smalltalk - Browse Categor, which is again available from the tools menu:

Browse Category

Try entering Printing:

Browse Category

And that wraps up a quick tour of the various browsers - leaving the version control related ones aside, which we'll cover in depth in a separate tutorial.

Poor Service

April 21, 2011 21:00:15.465

My wife has had no joy getting voice activated dialing to work on her new phone (a Samsung Transform running Froyo) - it simply refuses to use the bluetooth headset in a reasonable way. She'll tell it "Call Jim Cell", and it'll prompt her on the screen as to what it should do. Seriously?

This wasn't making her happy, so we headed to the mall to go to the Sprint Kiosk where we bought the phone a few days ago. There was a sign there:

We waited an hour, doing a couple of other errands nearby - the Sprint guy never came back. So now we blew an hour on that, and we still have this crap phone that doesn't do voice calling well. Awesome, Sprint - if you guys wonder why I plan to stay with Apple, you can read this post and ponder it a bit. They might cost more, but the customer service is always awe inspiring

Game Reviews as a Sport

April 21, 2011 9:24:05.869

This looks like the future of game reviews to me:

From hate to love back to unmitigated odium, it looks like Portal 2 customers are gaming review aggregator Metacritic in an attempt to both sabotage and rehabilitate the average user score by playing “score tennis,” tagging the physics puzzler with extreme scores and pithy appeals.

That happens to be about Portal 2, but you can see the same dynamic at work with Dragon Age 2. Probably with other games I haven't looked into as well. To see this for yourself, just google "XX Review", where XX is the name of the game you want to know about. Other than universally loved or hated games, picking through the plethora of results isn't easy.

Relying on the "major" sites isn't necessarily an answer either; I was listening to the Joystiq podcast on Dragon Age 2 yesterday, and it was clear that their knowledge of the game was superficial - at best. The best you can do is read widely, then make up your own mind as to whether it's worth taking the plunge.

ST 4U 72: Exploring VA Smalltalk

April 20, 2011 11:17:32.460

Today's Smalltalk 4 You looks at one way of exploring VA Smalltalk. One of the things I like to do with a system I'm not terribly familiar with is start from something I do know, and explore from there. In this screencast, we take a bit of code I know well, and use it to jump into the tools and system. If you prefer a written walkthrough to video, then skip down to it. 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:

Exploring VA

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:


One of the best ways that I know of to explore a new Smalltalk system is to take a piece of code I've written quite a lot in other Smalltalks, and start exploring the system using that as a jumping off point. That way, I'm not stumbling over both the less familiar system and the code at the same time. Translating that to VA Smalltalk, I took this as my starting point:


count := 1.
block := [[true] whileTrue:
				[count := count + 1.
				Transcript show: count printString; cr.
				(Delay forSeconds: 2) wait]].
proc := block forkAt: Processor userBackgroundPriority.


It's the core of just about every server process I've ever created in Smalltalk - except that the real ones do actual work instead of writing to the Transcript. For our purposes here though, this is perfect. Let's start by highlighting Processor in the workspace, right clicking, and selecting inspect. This is what you should see:

ProcessorScheduler

From there, it might be interesting to look at the implementation. So back in the launcher, select Tools>>browse class:

Browse Class

You should see the class browser, allowing you to start looking at the implementation:

Browsing Class

One thing that's different about VA, at least compared to Squeak, Pharo, or VisualWorks - look at the three tabs above the selector pane on the right - public, private, all. In VA, private methods are a bit more segregated. There's nothing in the system that prevents you from invoking a private method, but VA does make them visibly separate in a way that most Smalltalks don't. This makes it much more obvious when you are crossing the divide between a public API and a private one.

Now we might want to look at the actual Process class - we have one running, and it would be useful to be able to control it. Let's go back to the workspace, and inspect the proc variable:

Inspect a Process

Inspector on a Process

From here, you can browse the class directly. On the toolbar for the inspector, find the Browse Hierarchy button and click it:

Hierarchy Browser

Clicking around we spot the #terminate method, and we go back to the workspace, invoke that code and kill the running process:

Terminate a Process

In future tutorials, we'll start examining each of these tools - browsers and inspectors - in depth. Today's goal was to show you how you can use a small bit of pre-existing knowledge as a jumping off point to explore VA Smalltalk

Squeak for Android Progress

April 20, 2011 9:57:36.259

Dmitry Golubovsky has made some progress on getting Squeak running on Android:

I am glad to announce that the Squeak Port for Android Tablets [1] has reached its first milestone. Work has been done towards fixing certain usability issues such as better integration with Android Input Methods, access to local file system, etc.

There's more info at the link, including download info. The one big downside so far - no socket support yet.
