Introducing Antipasto Hardware Wiki

Over the past two months, Chris, Will, Nick, and I have stealthily upgraded and migrated all of the Liquidware wiki content over to a new wiki... the Antipasto Hardware Wiki.

I decided it was finally time to upgrade the wiki to a higher end system, and using pbwiki seemed like a pretty decent choice. It'll still take some time to finish the migration, but until then, the benefits are quite nice - the new wiki has a lot more features than the original Liquidware Wiki (which technically was an upgrade from the formerly-original wiki, over at the www.liquidware.org site, which doesn't even exist any more).

Not a big deal, but thanks for all the help - and hopefully this will help address all those emails about folks wanting more help finding reference specs and documents for Liquidware hardware.

Cheers!

How to build a BeagleBoard-based Open Source Ebook Reader

Ebook readers were hailed several months ago as the end-all-be-all of digital devices. They were supposed to put books out of business. In effect they have, they've put some book distributors out of business. But somehow, the Ebook itself is somewhat unsatisfying - after all the hoopla, we're left with "just" a screen tablet-like device, with a few buttons and a mini keyboard. It just doesn't feel like there's enough new to it... so I got inspired to build my own as a platform for experimenting with the "user experience" of Ebooks.

I got bored with my Kindle after about 20 times using it, and started wanting to hack it. I have a modern form of A.D.D. that makes me want to break open cases and solder memory expansion ports onto any device I touch. There's so much I'd do differently, yet you can't really do any development on it - I don't understand - they should just open it up, and let people like me hack away at it.

Since Amazon didn't, and doesn't, I decided to turn the Open SciCal into a hackable ebook reader, based on the FBReader source code. This means that it's hackable from the ground up...

It's not bad, but there are some things I'd change. Luckily I can, because the source is open and accessible... in fact, it's quite easy to understand - here's the important main function set, from FBReader, which gives a good idea of how approachable the code is (if you know C and C++, that is):

void FBReader::openBookInternal(shared_ptr book) {
    if (!book.isNull()) {
        BookTextView &bookTextView = (BookTextView&)*myBookTextView;
        ContentsView &contentsView = (ContentsView&)*myContentsView;
        FootnoteView &footnoteView = (FootnoteView&)*myFootnoteView;

        bookTextView.saveState();
        bookTextView.setModel(0, 0);
        bookTextView.setContentsModel(0);
        contentsView.setModel(0);
        myModel.reset();
        myModel = new BookModel(book);
        ZLTextHyphenator::Instance().load(book->language());
        bookTextView.setModel(myModel->bookTextModel(), book);
        bookTextView.setCaption(book->title());
        bookTextView.setContentsModel(myModel->contentsModel());
        footnoteView.setModel(0);
        footnoteView.setCaption(book->title());
        contentsView.setModel(myModel->contentsModel());
        contentsView.setCaption(book->title());

        Library::Instance().addBook(book);
        Library::Instance().addBookToRecentList(book);
        ((RecentBooksPopupData&)*myRecentBooksPopupData).updateId();
        showBookTextView();
    }
}

The Open Source Ebook reader is based on a handful of modules:

-BeagleBoard - the guts of my Ebook uses the TI OMAP
-BeagleTouch - it has a touchscreen OLED screen
-BeagleJuice - it's powered for 8 hours at a time with lithium ions
-FBReader - open source software, quite nice and hackable
-Liquidware Ebook Boot - an open source boot SD card with a tweaked version of Angstrom to integrate all the parts

The base parts are pretty straight-forward, they just snap together and go. If you're a hacker, you could build it all together pretty straightforward-like from source and use Angstrom. But if you're lazy, you can just buy the "Ebook Boot" SD card which took Chris and Will and me about 2 weeks of hacking around to build, from source, from scratch. It includes all of the drivers needed to get the touchscreen working within Linux, and a handful of libraries and scripts to make wifi, power management, screen control, etc. work right out of the box...

The fully combined stack of modules makes an Ebook:

Here it is from another angle, against a go table that I built by hand (those lines took forever, and were done with a heat iron, for wood carving, but it was so worth it):

This photo is probably the most "ironic" given it's a shot perhaps the most purpose-built hackable Ebook reader on top of the perhaps the most purpose-built non-hackable devices ever: a Mac laptop.

This is probably my favorite picture:

I haven't tried it yet, but conceivably, it could be connected to the net using the Wifi module, and then it could download Ebooks and free Ebooks from the various online stores that FBReader lets you connect to...

I've uploaded some pictures over on the flickr page, and the modules and finished EbookBoot SD Card are all available over at the Liquidware shop... I think I should run a timed contest against myself on how many different types of gadgets I can build within 4 minutes, like these guys that Make blog featured a little while ago...

:-)

Update From the Cross-Channel Integration Roundtable

The Cross-Channel Integration Roundtable met on September 6, 2011. Here's a brief overview of the meeting and the group's projects.

Attendees:

Colleen Petitt, Aprimo - Roundtable co-chair
Dwight Sholes, Sholes LLC - Roundtable co-chair
Adam Cooke, Garagefly
April Mullen, Scottrade
Jeanette Brown, Informz

The team has completed the publication of our first project the “Cross Channel Marketing Guide.” This report provides ten guiding principles of a successful cross-channel marketing program and includes specific goals and actions your organization can apply to build a thriving program. We finalized group input in this call and the Guide is available in the eec Research Store.

Our next topic was our next project. The team determined that we would first like to create a survey of digital marketers to determine where they are in the continuum of integrated cross-channel marketing. In our meeting on 10/4 we will begin to work on this project.

The group also decided that we would like to subsequently develop a cross-channel audit that will allow marketers to assess where their strengths and growth opportunities are within cross-channel marketing. Marketers will then be able to leverage the guide to improve and enhance their capabilities in each area. We will discuss this further in our 10/4 meeting and determine how we can use the survey to develop the audit.

Interested in joining the Roundtable? Email Ali - aswerdlow@the-dma.org.

Free Alternatives for .NET Reflector

As I use to start stories to my kids when they go to bed:

?A long long time ago when I was a kid there existed a tool called
.NET Reflector, by a great wizard called Lutz Roeder. This wizard created
a magical tool that allowed you to discover what where the dark forces of the
Framework that produced weird behavior. And he provided it to the code warrior so
they could find their path?

Well .NET Reflector still exists and is a great tool, but is no longer free. You can no longer
just download it and enjoy its bliss : S

But is everything loss. Should I sell my sword and horse to be able to use the .NET reflector Oracle ???

No. There are now good free alternatives.

First one is call ILSpy(http://wiki.sharpdevelop.net/ILSpy.ashx). It looks almost the same as .NET reflector. Is not the same but is very good

And recently JetBrains a clan of powerful code warlocks, has just release another magical jewel,
they called it dotPeek (http://www.jetbrains.com/decompiler/):
