ST 4U 126: Adding Style to a Seaside Application

August 29, 2011 0:53:08.656

Today's Smalltalk 4 You continues the VA Smalltalk Seaside tutorial with CSS. Today we'll add that support directly in the image (application code) - next time, we'll look at external file resources. 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:

CSS.

In this section we'll add some CSS to our application, directly in the image. IN a future tutorial, we'll look at adding external file resources (images, CSS files, etc) as well. To start with, go to class BlogServerView and add the following method:


style
	'h1 {color: green; }'

You can put arbitrary CSS in that method - the CSS you add will apply to the component you add it to. Now, refresh the view in the browser:

Styling

That's it - this method is useful when you want to hand a prototype over to someone else with a minimum amount of fuss - you simply give them the image and the VM, and off they go. Next time we'll look at adding external file resources to our application

Pharo Powers Forward

August 30, 2011 20:47:19.799

Spotted in Planet Squeak

Pharo 1.3 is in release candidate mode. The last action needed for release is to package the OneClick image with the right Cog VM. On this side Igor is working on a few critical fixes that should be ready in a couple of days. So you can put the Champagne in the fridge now. Pharo 1.4 is in alpha mode. Note that starting from 1.4 only one image will be released. Releasing two images actually needs too much effort for our community. Furthermore the core developers usually work on PharoCore and it's hard for them to follow bugs on a image (Pharo) they don't use. So one small image with easy package loading (and unloading) seems a better way to go. Only one Pharo. About infrastructure, continuous integration server is moving from Hudson to Jenkins. The Hudson server will be stopped when the migration is finished. For Cog VMs, Pharo 1.4 and current projects, check the Jenkins server.

Lots of interesting things happening with Pharo these days...

ST 4U 127: AidaWeb and Domain Objects

August 31, 2011 7:38:49.736

Full Bore Polymorphism

August 31, 2011 22:58:59.323

Torsten Bergman explains just how deep the Smalltalk polymorphism rabbit hole goes:

While a function/method name in a class has to be unique so it could be called it usually is a Symbol. You know all these #foo, #bar, #negated, ... In Java you may call it foo() or bar() or negated(). But in Smalltalk this selector could be ANY object. Yes, yes - this is not a type.

More Stupidity on Copyright

September 1, 2011 16:35:53.000

The drive to "protect" intellectual property is getting dumber, and it's not limited to the US - Look at what's happening in New Zealand:

The Government's Copyright Amendment Act comes into force today and anyone caught downloading copyrighted content illegally could face fines of up to $15,000 and have their internet cut off.

So say you run a Starbucks in New Zealand, and someone decides to download a few songs via bittorrent while they have a latte. That leaves Starbucks open to the penalties.

The unintended consequences of this are going to be really, really bad.

Redline Reboots the Blog

September 2, 2011 21:13:43.424

James Ladd is rebooting the Redline blog:

What still needs to change are some of the posts here that are no longer correct as they don’t refer to the current implementation of Redline Smalltalk. I’m confident the current incarnation of Redline will be the one that makes it to a V1.0. As such it is now time to delete these old incorrect posts and begin a new series that is correct.

Parallels 7 and Gaming

September 3, 2011 10:52:25.442

I downloaded Parallels 7 last night, and immediately tried out two games: Deus Ex: Human Revolution (which I've been playing in 6) and Fallout: New Vegas (which I played extensively in 6). Deus Ex was laggy in Parallels 6, and while it's not perfect in 7, it's much better. The real change was in FNV.

As I documented here, you had to muck around to get FNV to play at all in Parallels 6. In 7, you don't. If you did muck around, you need to remove the d3d9.dll file you tossed in for it to work in 6. The graphics look a lot better after that, too. So far, so good - I think Skyrim will be the big test though :)

Squeak on Android

September 5, 2011 13:19:59.808

Looks like you can get Squeak for Android now, although it's still early days:

I am pleased to announce that the Android port of Stack Cog has reached the public alpha stage, and the first pre-built apk file is available for downloading. This is a debug-signed Android package. When installed, it uses the Pharo icon (to distinguish from the Squeak package in case it is installed). In the future, I'll change the icon to something different.

Real Competition for Apple

September 5, 2011 17:45:41.808

Amazon has enough content available to make a real run at the tablet space - and it looks like they are primed to get in:

It’s called the Amazon Kindle but is different from other Kindles. Siegler says he actually used the design verification version of the 7-inch tablet, which is due for release at the end of November and will be priced at only $250.

Micro USB port, WiFi only - and free Amazon Prime for a year. I really like my iPad, but that's a pretty darned attractive sounding deal...
