Irony Not Dead

May 26, 2011 8:50:42.000

I saw a reference to the book "Dancing with Digital Natives" on David Meerman Scott's blog, so I went to Amazon to have a look - figured I might want the ebook. Utter fail - the book is out in dead tree only.

Stuck

May 26, 2011 16:08:06.274

Looks like it's one of those travel days. First, I finally had to deal with one of the new scanners. I opted out, of course - if TSA wants to run security theater, the only protest I can lodge is to waste their time. With that out of the way, I got onto an earlier flight headed to DCA instead of BWI (good news, since I forgot about my bifurcated flights this week and parked down near DCA).

That's pretty much when the good news ended though; now we have about 90 minutes of ground hold, due to T-Storms between here and DC. Joy :)

ST 4U 88: Another Route to the VA Debugger

May 27, 2011 6:59:37.386

Today's Smalltalk 4 You shows you another way to get immediate access to the debugger in VA Smalltalk - the little "Debug THis" window that appears in the lower right corner of the screen when you start up the development environment. 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:

Debug Any ST Process

The video at the link has been reformatted to a smaller size; you can view the full size video as an MP4, or in Windows Media Format.

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 look at another route into the debugger in VA Smalltalk, which can be useful when trying to grab the foreground process. To show that off, we'll again create a Smalltalk process in the workspace, and then grab it with the debugger. Here's the code to kick off a simple process:

Fork a Process

Now, when you started up VA, you may not have noticed the tiny little window in the lower right hand corner. It has one button, and gives you immediate access to the Debugger:

Get a Debugger

If you click that, instead of an empty debugger (which we saw in the last tutorial), you'll get the foreground process:

Open the Debugger

Now you can follow the same steps to debugging/terminating the errant process, via the Debug Other menu pick:

Debug Other Process

Lets Break the Internet

May 27, 2011 10:07:17.937

In the annals of stupid, this is pretty high up - a Senate committee wants to break the internet:

The legislation will allow the DOJ to target the "worst of the worst" foreign websites dedicated to digital piracy or selling counterfeit goods, said Senator Patrick Leahy, a Vermont Democrat and lead sponsor of the bill. Intellectual property theft is "unacceptable," Leahy, chairman of the committee, said in a statement.

This is great - the practical impact would be to have a set of alternate DNS servers pop up. Instead of the mostly unitary net we have now, we'll have chaos. That seems to be what Congress does best though...

Where is Facebook on the iPad?

May 28, 2011 18:50:58.000

TechCrunch asks an excellent question - where the heck is the iPad app for Facebook? The iPhone app looks kind of stale for that matter - maybe they can't find anyone to replace the guy who famously declared that he wasn't doing that work anymore (which should have led to his immediate termination, IMHO, but that's another story).

So here it is, 2011, and there's still no iPad app - meanwhile, Facebook is looking for help on the desktop:

On the jobs page for the relatively new Seattle Facebook office, one of the openings is for “Software Engineer, Desktop Software”. Desktop software. Desktop. Before the damn iPad. Hey Facebook, 1986 called, they want their strategic vision back.

Apparently, this is the start of some big team. I think TechCruch is right - they lost their calendar, and think they are living through a re-imagined "Back to the Future", set in the 80's....

How Bad is Protect IP?

May 29, 2011 10:43:49.482

I was ready to just call it stupid the other day - now I see that not only is it stupid, it's actually dangerous in a lot of ways. That's Congress for you - they can't limit themselves to being stupid, they have to do actual harm while they're at it.

At this point, I think the cost/benefit for both copyrights and patents have flipped. Unless both are reformed in a "start from scratch" sort of way, we'd be better off without them.

IM 31: Seaside and Rails

May 29, 2011 20:08:21.785

Welcome to episode 31 of Independent Misinterpretations - a Smalltalk and dynamic language oriented podcast with James Robertson, Michael Lucas-Smith, and David Buck.

This week I have another session from Smalltalk Solutions 2011 - Pat Maddox, talking about using Seaside and Rails together. The abstract for the talk was:

Ruby on Rails has proven to be the best framework for developing open applications and platforms on the web. Seaside excels at building intelligent applications by hiding the complexity of session-based user interaction. This talk will highlight the strengths, weaknesses and impacts of each of these frameworks, and will examine how to use them together to build open, intelligent applications.

You can subscribe to the podcast in iTunes (or any other podcatching software) using this feed directly or in iTunes with this one.

To listen now, you can either download the mp3 edition, or the AAC edition. The AAC edition comes with chapter markers. You can subscribe to either edition of the podcast directly in iTunes; just search for Smalltalk and look in the Podcast results. You can subscribe to the mp3 edition directly using this feed, or the AAC edition using this feed using any podcatching software. You can also download the podcast in ogg format.

If you like the music we use, please visit Josh Woodward's site. We use the song Troublemaker for our intro/outro music. I'm sure he'd appreciate your support!

If you have feedback, send it to jarober@gmail.com - or visit us on Facebook - you can subscribe in iTunes using this iTunes enabled feed.. If you enjoy the podcast, pass the word - we would love to have more people hear about Smalltalk!

Making Storage Simpler

May 30, 2011 10:19:05.401

Sean DeNegris talks about simpler data storage:

In an enlightening blog post, Ramon Leon explains that most applications are designed for small businesses with small amounts of data. Therefore  most applications will never have to scale (i.e. become the next Twitter), so a relational database is overkill. However, persisting by simply saving the image is slow and error-prone.
Based on these ideas, he suggests a simple (one class) framework which saves only your model. The idea is to use it as long as you can get away with, which may be forever.
I packaged the code from the post, added a few tests, and put it on SqueakSource as SimplePersistence.

You have no idea how many security headaches I've avoided by using binary serialization to store the posts on this blog instead of a SQL Database. As with Sean's example, my storage needs are lightweight, and a relational database would be overkill. Not to mention being an attack vector....

JS 4U 60: JQuery No Conflict

May 31, 2011 9:48:49.874

Javascript 4 U

Today's Javascript 4 You. Today we look at using the JQuery noConflict() function. It's common to make use of multiple Javascript libraries in a web app, and some libraries might also want to use the $ symbol for variable access. Never fear - JQuery has a way to deal with that problem. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube.

Uniscribe Interface in Smalltalk

June 1, 2011 8:29:57.000

Travis has been working on an interface to Uniscribe:

I've been working on a Uniscribe interface to VisualWorks Smalltalk off and on for the last two weeks or so. One of the frustrating things for me so far, is the lack of a good post-doc resource to go to for help with this stuff. There's the MSDN docs, which are OK, but when you have questions beyond that, I have as of yet, not found any of the resources I'm used to using for this kind of thing, such as mailing lists, etc. And the amount of "tutorial" style pages out there is pretty small. So I thought I'd at least leave a trail of breadcrumbs here.

Why Nokia Bailed on MeeGo

June 2, 2011 8:54:33.674

Engadget has the scoop, and it's interesting - basically, Nokia did some actual introspection, and determined that they couldn't get where they needed to go with their own OS - so they partnered with Microsoft. A lot of companies could benefit by looking at their own strategies with as much of an open mind as Nokia apparently did.
