You may never have heard of ACCU, the Association of C and C++ Users as it was originally called. It is a volunteer organization, consisting of programmers who care about programming. The ACCU publishes two magazines, both devoted to raising the standards of programming everywhere: C Vu and Overload. On top of that they organize a conference every year, where some of the top names in C/C++ programming (and many other software development fields) come to speak and mingle with programmers from all around the globe.

I was introduced to the ACCU several years ago, when I first came to Silicon Valley, and still renew my membership every year, even though I don’t attend the local ACCU-USA events anymore. Yes, there is a local “chapter” of the ACCU in Silicon Valley, and they have monthly events that you can attend for free. I had the good fortune of hearing Bjarne Stroustrup speak once (plus going to dinner with him and the rest of the attendees afterwards, and even getting to exchange a few words with him in private.)

At one time I also co-hosted an event for the ACCU, and I think it is this personal connection that has kept me going as a member, even though I’ve not been much directly involved since. What keeps me hanging on now are the two excellent journals, which are largely ad-free and contain almost nothing but passionately written articles and code samples, demonstrating how to become a better programmer.

If this is something you strive for, I highly recommend checking out the ACCU and encourage you to become a member. Even if you live in the United States or elsewhere outside the UK.

I just noticed that the development guidelines for how to write an application that works with the HP TouchSmart software has been made available for download.

Go get it at http://www.touchsmartcommunity.com/download/60/HP-TouchSmart-Software-Developer-Guidelines/

There’s a license agreement you need to read and agree to before you download. Please read it carefully.

The document is not what I would call a “proper” SDK, since there are no “header files” or anything of that kind. The nice thing is that our “interface” is at the hWnd level, so pretty much any way you want to write a touch-optimized windows app should be able to work in the HP TouchSmart environment.

One more thing: you need to also download the update to the HP TouchSmart software itself, otherwise you won’t have the ability to “register” your application with the TouchSmart UI. That update is available here: http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=pv-66420-1&lc=en&dlc=en&cc=us&product=3752240&os=2100&lang=en

[Edit 2008-11-20: The update was taken down for a while, for fixing an issue that was found after initial release. This is the new link.]

[Edit 2008-12-07: Looks like the link moved once more. Hope it stays for a while now. The SP number is sp40894]

So there you go, have fun writing some apps, and show them off through the community site. No need to wait for Windows 7…

Here’s the summarizing headline/link:

The TouchSmart Has Improved–But Not Enough

I’m surprised at how relatively positive the article is. Thanks Mr. Mossberg!

The big day is here and gone. The new TouchSmart PC has been announced to great fanfare on the web, and I’m sure there’s more to come. The blogs are full of praise and criticism already, of course. Since I was closely involved with the creation, I’m happy about all the praise and hope that we’ll be able to address the criticism over time (especially regarding the software). In other words: there’s never enough time to get any piece of software 100% smack-dab perfect for everyone’s taste.

I’d like to write a little about things that may not be well known yet. Yes, there is actually limited “dual-touch” in the new software. You can resize the upper row of “tiles” using two fingers. You can scroll using two fingers once you’ve gone into the “Browser”. Due to how the touch screen works you need to make sure your fingers are a certain distance apart to get it to work right. It’s “limited” dual-touch because of the natural laws of time and resource constraints on the development team: we ran out of time to do more.

Oh, and nowhere in the HP TouchSmart software do you need to “double tap”/”double click”. If a single tap doesn’t do it, the touch screen saw too much movement of your finger during the tap and turned it into a move action instead. That’s the challenge with using optical technology that sweeps just above the glass. It sees your finger a little before you actually touch the screen. (Think Vincent Cassell in “Ocean’s Twelve” or Catherine Zeta-Jones in “Entrapment”)

We’ve had feedback from users in the past, asking for tutorials around the software. I’m personally really happy that we managed to put two tutorials on the system for this new incarnation of HP TouchSmart. And they are available right from the lower row of “tiles”. Here’s a small taste of how the tutorials were created:

As you may be able to see, there’s a lot of work that goes into even such a small thing as creating tutorial videos. I certainly had no idea how involved the process is before I had the chance to help out with the production in a (very) small way. I feel lucky to have worked with and met so many great people. You can find the tutorials here, starting with the basic one in English.

For those of you who read this blog because of the WPF topics I’ve touched on in the past: yes, central parts of the software were created using WPF. I don’t mean to be a fanboy, but I’ve said it in the past, WPF is powerful stuff. The ability to have separate people working on styling the software while other people work on “business logic” is incredibly valuable. At the end you get full visual fidelity of the design for virtually no added work.

Before I close (and this gets much longer), let me put a question out there for software developers. If it were possible to write software that could end up as “tiles” in the TouchSmart software, would that be interesting to you? If not, why not? Don’t take this question as any indication or promise of what the future may hold. I’m just curious about your opinion. Comment away, please.

And for those of you who just stumbled upon this by chance (or dug through the sea of noise out there) and are curious about certain aspects of the new HP TouchSmart PC or the software, I’ll try to answer questions within certain limits in the comments as well.

The rest of this post is mostly a collection of links I gathered on the day of the announcement, with a little added commentary for myself. What a splash!

Trust me when I say it takes a little getting used to, but it works pretty well after that. We did lots of usability studies on this puppy.)
