ST 4 U 28: Multi-Select ListBoxes in VisualWorks
Today's Smalltalk 4 You looks at an issue I ran into with VisualWorks at my new job: the way listboxes with multi-select turned on behave with drag/drop. I've posted the code to the package MultiSelectPatch in the Public Store Repository. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube.

The Diner Lives!
How did I miss The Diner returning? I love Lileks' stuff, and the podcast seemed to disappear in 2009 - there was a gap between March and October, and I just dropped the subscription. Now I wish I hadn't!

Cable and Telcos Win
I hope all of the people who've been pining for network neutrality know what they just got from the FCC - it's a huge win for the existing carriers and cable companies. Why do I say that? Take this statement:
"A commercial arrangement between a broadband provider and a third party to directly or indirectly favor some traffic over other traffic in the connection to a subscriber of the broadband provider (i.e., 'pay for priority') would raise significant cause for concern," the Commission then elaborates. This is because "pay for priority would represent a significant departure from historical and current practice."
So to take a for instance - NetFlix couldn't pay to get priority for their traffic. Meanwhile, the local cable outlet (or telco) ships video on demand down the "cable" channel (although it actually comes down the same pipe), and gets to prioritize the heck out of it.
I sure hope all the idealists are happy now. The only good news here is this: based on recent court decisions, it's likely that the FCC overstepped its authority. I certainly hope that's how this plays out.

Fallout New Vegas DLC: Sierra Madre
![]() |
I spent a fair bit of the evening playing the new DLC for Fallout: New Vegas
|
Mind you, there are huge differences as well. I was able to run through Pitt and find all the guns, ammo, and armore I wanted. Theer seemed to be plenty of stimpacks lying around too, as I recall. In Sierra Madre, that's just not the case. There's virtually no guns or amm to be found - I've been pumping up my melee skills since I started it (the level cap goes up to 35 with this dlc). Still, my health has been running at 50 percent or less most of the time. The only health I manage to find is out of the vending machines, and that requires me to find lots of casino chips. To be fair, those are all over, albeit in small-ish numbers.
You also lose your entire party - again, a lot like "The Pitt". Inside, you end uphaving to take the crew you find and deploy them to various places on the map (and convince each of them to stay there) as you go off to open up the casino proper. That's as far as I've managed to get - I was on my way to the bell tower when I ran out of time for the day.
My advice? Bring in a leveled up (at least 20th) guy with both melee and survival pushed up. Your gun and energy weapon skills just won't help you that much.

Should Be a Disqualification
The fact that the people in charge of the FCC actually seem to believe this tells me that they have no business regulating anything more complex than their utensils drawer - and that might be pushing it:
the release says that only "measured steps" to regulating wireless are necessary because "open operating systems like Android" have been released, and that it wants to see how Verizon and other 700MHz spectrum winners handle the hotly-contested openness requirement when building out 4G.
Right... because how a carrier handles bits over the air has so much to do with what OS is running on the receiving device. I'll be over here, in the corner, laughing my whatever off at all the clowns who think the FCC is doing anything useful.

Broadcast TV: Sports, and not a lot else
The rise of various streaming TV options - from DVRs to Netflix, Hulu, iTunes, (etc) - has done a fair amount of damage to the traditional "appointment tv" model. Now there's some real evidence of what the future of that model looks like: sports:
Of the 20 highest-rated telecasts of any kind so far this television season, 18 have been N.F.L. games on CBS, NBC or Fox. In terms of the best of 2010, nothing else comes close. Of the 50 highest-rated programs during the calendar year, 27 have been N.F.L. games, including 8 of the top 10.
This makes perfect sense to me - watching recorded games is hard, because it's just too easy to hear about the results elsewhere. Beyond that though? Most shows now have a niche audience, which means that it's pretty easy to avoid spoilers.
Beyond mass audience things like NFL games though, it makes the standard ad supported model harder and harder to justify.

Pier, Podcasting, and Tools
I found this interesting, because it's ground I've mostly covered with my Silt server - things like iTunes enabled feeds, XML-RPC interfaces for posting tools, and so on:
In which I hope to adequately explain how I used PierCMS to launch my new podcast, Those Optimize Guys.
Sergio advocates using Feedburner, which does most of the work for you. Probably a decent idea now, but I like the fact that all generation is under my control :)

Seaside and AidaWeb
Robert Shiplett compares Seaside and AidaWeb for his end goal- generating Curl rather than HTML:
The Aida 6 web framework is rather different in objectives than Seaside 3 as a Smalltalk application server. My specific interest was to determine to what extent the services for web applications were orthogonal to any given web markup. Both default to HTML but I am looking at frameworks suitable for emitting declarative Curl markup using the Curl web content language (originally MIT and now Sumisho.)

This is Overload?
I have two - count 'em, two - strings of lights across my doorway and the step railings outside:
As I was plugging them in, they went out. I thought one string had dropped a fuse, so I went looking for replacements - and found my battery backup in the basement (the one I use for the router) beeping. The ground fault on that plug had popped. How the heck are two lousy strings of lights an overload state?
Why Smalltalk is Cool
The two things that you spend most of your time doing as a programmer — coding and debugging — are made noticeably easier and more fun by that combination of Smalltalk language and IDE. The language syntax is small, powerful, expressive, introspective. The entire stack (and libraries, and IDE) is written in Smalltalk (turtles all the way down), and you have access to the source code, allowing you to study and extend all operations, basic and complex. The code organization — explicit, first-class visual IDE support for packages, classes, protocols (groupings of methods by intended use) and methods — is extremely helpful.
Follow the link and see what he says about the debugger - non-Smalltalkers often miss the power of the debugger in Smalltalk.

If the World was Ending Soon...
I just finished reading a very interesting book - "Spin" by Robert Charles Wilson. I also finished the second (of three?) books in the series, "Axis
". The books are connected, but can be read separately - it does help to read Spin first so that you know how things got to be the way they are.
While the setting is near future, and it's clearly a sci-fi setting, it's mostly about the people. I became very attached to a number of the people - one thing I will say is that Wilson is not afraid to kill off characters, even ones that have become quite central to the story thus far. That keeps you reading - no one is safe. I'm looking foward to book three, and if you like pondering how people would collectively and individually handle a presumed apocalypse - that then doesn't play out as the worst fears had it - these are great books.

The Digital Switchover
I've always been a big reader - I just finished two sci fi books on my last trip to Dallas (I still need to post the reviews for those). What I'm finding lately is this: I'd much prefer to read on my iPad than read on paper.
Why? A few reasons:
- The iPad is light. I can carry as many books as I like on it, and it doesn't get heavier
- I can buy a new book anytime I have access to the net
- I don't ever have to worry about losing my place - the Kindle app manages that for me
I think the weight thing is the big one. I'd really rather not cart a bunch of books in my travel bag - especially since they are just so much dead weight after I've finished. Even with books I've been waiting for, like Towers of Midnight - I'll wait for the digital edition. The hardcover is too big, and even the paperback (when it comes out) will take up a lot of space.
I just want the bits :)
There's English...
And then there's what PR and Marketing types at Yahoo speak. It's like English, but with all the meaning removed :)

And it goes without saying that it's cold :)
It's a Business
Mariano Rivera admitted the unthinkable had been a possibility. — The Boston Red Sox offered him a chance to turn in his pinstripes and switch sides in baseball's fiercest rivalry. — “It was real.
I follow baseball pretty closely, and I'm a big Yankees fan - but this is one of those periodic reminders that it's primarily a business, not something put out there for the sole enjoyment of the fans. When that fourth wall breaks (think Babe Ruth going to the Yankees, or his late career away from the Yankees), it makes that all the more obvious.
Good TV Dies Again
Syfy announced today it will end its original action-adventure series Stargate Universe once the show returns to finish its second season in the spring of 2011. The upcoming 10 episodes will be the series' last.
I find it depressing that well written shows like this just don't find a place.

Seaside at OSDC
Last month Julian Fitzell gave a talk on Seaside at OSDC in France. I've embedded the talk below - it starts in French, but flips over to English pretty quickly. Here's a summary for the talk:
Are you tired of marshaling state, mapping URLs, and making sure your form fields all have unique element IDs? Do you long for a better way to develop for the web, without editing XML files? Do you ever wish complex online applications actually let you use the Back button? Seaside frees you from these burdens, leaving you to focus on creating the applications that can make or break your business.

Who Cares About your Products?
David Meerman Scott says this kind of thing a lot:
For years, I've been saying that to create great Web content, you need to always be thinking: Nobody cares about my products and services except me and the others in my organization. What your buyers do care about are themselves and they care a great deal about solving their problems (and are always on the lookout for a company that can help them do so).
The thing is, it's true - but only to an extent. In the process of telling people how you can solve their problems, you have to get into the how - and presumably, that involves.... your product(s). So yes, no one cares about your products - in the abstract. What they might care about is how your products can be used in their domain.
In order to get there, you do actually have to - *gasp* talk about your products. Because cutesy videos might attract a lot of views, but if they don't relate you and your products to a live problem, that's all they do.

Build Automation
One of the things I've been asked to look at here is build automation. Right now, all builds are done manually, using RTP - and sometimes, based on various things going on, they need multiple builds done per day. As you can imagine, that takes up a lot of staff time, and adds in an error prone personal component to the process.
Now, I'm hardly an expert in such things, and for that matter, there are entire toolsets devoted to this field. Having said that, I do have a set of build scripts for BottomFeeder, so I have done some work here. When I sat down to look at what I do for Bf, I realized that while I've automated pieces, I haven't automated everything. So, I created a small (very small) tool to tie my process together. We'll see whether or not it scales up well enough to use for the problem at work, but that's in the future.
Right now, here's how I do BottomFeeder builds:
- Execute a Smalltalk script that creates a runtime image
- Execute a second Smalltalk script that uses image compression tools to shrink down the image file for deployment
- Run a shell script that creates the various zip files I throw up to the server
- Manually use sftp to ttransfer the files
Not as automated as I'd like :) I wrapped the first three things up with the tool I created - the last bit will require some research on my part - I haven't done unattended sftp in a shell script before, and unlike stock FTP, it's not something I can do in Smalltalk out of the box. So how does it work? Simple, really - I have a key=value ini file that describes each script that will run. The one for BottomFeeder looks like this:
[ScriptInfo] starter='./startvw ' script='build-bf-non-windows.st' assertion='build-bf-non-windows-assertion.st' isVWCommand=true [ScriptInfo] starter='./startvw ' script='compress-bf-image.st' assertion='compress-bf-image-assertion.st' isVWCommand=true [ScriptInfo] starter='./startvw ' script='executeBuildScript.st' assertion='executeBuildScripyt-assertion.st' isVWCommand=true
Basically, each section describes how to run the script, whether it's a VW script or not, and an assertion script to go with the build piece. That assertion piece is just a small bit a of Smalltalk that should return a boolean, explaining whether the associated build script worked or not. Then I put together a (very simple) UI that lets me pick a script to use, and see the results. Heck, I even have tests :) That window looks like this, after I ran my test script:
That's pretty much it, really - there's plenty that could be done, and it's hardly the best build system in the world - but it suits my purposes well enough, and automates what was a tedious build process. Whether it scales up for a real project - I'll find out soon enough :) If you're interested in taking a look, load the "BuilderBundle" bundle from the public store repository. I'm happy to hear any comments, good, bad, or indifferent.
