Can't Quit Qt

I’ve been dorking around with DeskBlocks lately, trying to find a way to get things to build & run within OS X. My ODE references were already many versions behind and the physics codebase is in need of an overhaul. Looming overhead was also the issue that Nokia was not entirely dedicated to the Qt4 platform that DeskBlocks is built upon, so I started to debate if I should find a new framework to build DeskBlocks within. I was pretty down on Nokia’s acquisition of Trolltech back in January of 2008, although it kinda made sense for the maemo platform. Still, with Nokia going all-in for Windows Phone it seemed like maemo and Qt was heading for the dustbin.

Sure enough, last week Nokia announced it was selling off Qt to Digia Oyj, even reportedly taking a significant loss in the process. Digia had already been running Qt licensing since 2011, so it’s not a huge surprise for it to take over the whole kit and kaboodle.

I’m of the mindset that this could potentially be a very good thing for Qt. I’ve seen Candyland get paved over so many times in the past decade, with big industries wrecking my favorite technologies over and over again. Going smaller may make things more agile - and it seems like many in the Linux community might agree. In a very smart move, Digia has already written an open letter to the KDE community emphasizing their commitment to Qt going forward. If they actually follow through on this dedication to the ecosystem, this could be a huge win for Digia Oyj.

Finland wins yet again.

Candyland Gets Paved. Again. Repeatedly.

I'm getting a bit tired of being so curmudgeonly. I can't help it tho. All my toys are being taken away.

First Novell acquires SuSE Linux, which I have been fairly skeptical of since the purchase was announced. Then Nokia ate Trolltech, the place where my favorite Qt was grown. And then Oracle ate Sun Microsystems, the ones who kept expanding the boundaries of software engineering and releasing such leaps to the public (usually (sometimes)). Now Oracle is smacking around robust and growing projects that have served the software engineering good for many years now.

And now Novell is bought by Attachmate, with 882 patents being absorbed by a Microsoft subsidiary. The openSUSE team says everything is "business as usual,", but there are very strong indications that this will not always be so.

Maybe this is just the ebb and flow that is technology capitalism... but all my power tools seem to be disappearing. If Apache and JBoss are bought by Philip Morris, I'm going to freakin' lose it.

Consumerism Gone Wild

I'm still comparing smartphones. Because I'm a big dork.

Judging solely on hardware, the n900, iPhone and Sholes are in a dead heat. The n900 and Sholes will have expandable memory options however, making them more appealing. The Hero completely lacks OpenGL hardware acceleration... a real downer.

I'd like to develop apps on the handset also. Mebbe to distribute or sell... mebbe just for a lark. With the Hero I wouldn't have any graphics acceleration which makes game development a pain in the butt. I don't want to compromise vertex counts and lighting algorithms. As far as market share goes everyone but Maemo comes out just fine... Android and the iPhone will be neck-and-neck in the foreseeable future.

There is also the question of price and carrier. Unless T-Mobile picks up and subsidizes the n900, the price is a bit prohibitive for me. While I don't actually talk on the phone that much (which may seem weird considering I'm so intent on shopping for smartphones) I do want to actually have coverage and intelligible audio, so AT&T is out. Verizon's data plans are too pricey for my liking. This leaves us with Sprint & the Hero.

How freakin' frustrating. I guess we can just wait until October and see how everything pans out, but right now the worst hardware (of the four) is dedicated to the best carrier, and the best hardware is dedicated to the worst carrier(s).

Cellphone Crysis

The smartphone wars are finally on. I love the irony... first the cellular carriers said pre-paid plans would never take off, then the European (and veeeeeeery slowly American) markets proved them wrong. Then they thought that having a closed platform and refusing to let independent developers write apps would allow them to market "exclusive" content, and Apple drop-kicked that notion in the groin. Finally carriers posited the Blackberry theory of economics where only business users would pay for unlimited data plans. And now Sprint, T-Mobile and AT&T have cost-effective calling plans for personal use. In fact, Sprint just announced $70 "everything" plan to really give T-Mobile and AT&T some competition.

All this fighting and vying for consumer dollars has worked on my feeble willpower. I my brain is pretty suggestive when the marketing war machine comes charging at me. I'm at the point now where I've self-justified the purchase of some smartphone in my near future, especially since I'm going to be re-negotiating my contract in the coming months. This is a complete 180 degree turn-around for me... three years ago I swore off multipurpose devices entirely because of my craptastic PalmOS smartphone.

This is a new era however. Now phones can have OpenGL acceleration, hardware video decoding, unlimited fast data access and capacitive high-resolution touch-screens. The PowerVR mobile chipsets are especially compelling, offering decoding and OpenGL ES acceleration using tile-based rendering.

Currently the only readily available smartphones with hardware-accelerated OpenGL are the iPhone 3GS and the Palm Pre, with the Motorola Sholes supposedly launching with Android and PowerVR soon. However, Palm quite stupidly offers no way for developers to tap into the power of hardware-accelerated OpenGL with their inspid WebOS SDK (as far as I can tell). Supposedly Motorola's Sholes will offer PowerVR acceleration with OpenGL ES soon, but it's landing on the overpriced Verizon network. And the iPhone's exclusive carrier AT&T has reputation for poor service and dropped calls; indeed most people I speak with on their network drop or cut out. Ultimately Nokia's n900, which runs on the custom Maemo OS and a PowerVR chipset, would offer the best platform / hardware combination of any other smartphone out there... but the hardware purchase currently isn't subsidized by any carriers and so is a bit prohibitive.

Out-of-the-box VPN connectivity is important to me also. I connect to clients using Cisco's VPN gateways (using vpnc) often as well as OpenVPN. With Nokia's Maemo OS I can do both vpnc and OpenVPN, with iPhone OS 3.x I can do Cisco VPN IPSec, and with Android I can do neither (without root access). However, ports of vpnc and OpenVPN clients are likely in the future with Android, since it's a Linux-based embedded system that does support tun devices.

With Sprint wanting to win the smartphone war on its own CDMA network it has made some compelling decisions. Their consumer-friendly data plans are nice, but it's upcoming launch of the HTC Hero means it has a well-received handset to push the service as well. Engadget reviewed the European model a little while back and thought it seemed like an ambitious OS on insufficient hardware, nagged by stuttering and slow rendering. Their review of the US Sprint model found the exact same issue, however CrunchGear gave the smartphone high marks and said it doesn't suffer the same stuttering and lag that previous incarnations of the Hero suffered.

So which to choose? The iPhone GS definitely has superior hardware, but its current exclusive carrier makes it a hard pill to swallow. Why by a smartphone when the "phone" part doesn't quite pan out? The Palm Pre has a great UI and fantastic hardware, but the developer SDK is limited and so independent development is stifled. The n900 would be fantastic - it uses Qt 4 for application development, has a very open SDK and OS and runs on some great hardware. If the n900 could find a home on a good carrier that would subsidize it's purchase, it would easily be the #1 contender.

Is Sprint's Hero the best choice? It hasn't even launched yet... it's due October 11th... but it already has been opening to good reviews. However the Hero appears to not allow root access and doesn't permit tethering, limiting my ability to tap into the subsystem and have vpnc or OpenVPN clients running. It also lacks hardware acceleration such as the PowerVR chipset, although it does offer OpenGL ES support via software rendering. Sprint's carrier service is quite good - however I'd have to compromise on both of my "must have" features.

Bleh. Maybe I'll just wait until Q4 and see how this all pans out. Right now there's no phone that has a reliable carrier, hardware accelerated OpenGL and OpenVPN clients. Or maybe I'll just buckle because my self-restraint is remarkably weak.

Two Great Tastes - maemo & Qt

Fresh off the wire, it has been announced that Nokia will introduce Qt, my favorite C++ toolkit, to the maemo platform, my favorite portable hardware platform. Two great tastes that go great together.

If this kind of platform expansion and cooperation with Qt developers (such as KDE authors) is what will come of the Nokia acquisition of Trolltech, it may not be as bad as I predicted. Here's to hoping that Nokia sees Qt as a toolkit that will serve mobile, embedded and desktop platforms. Especially with the recent fame of low-cost low-footprint laptops, Qt and maemo have to be getting some additional attention.

If the WiMAX-enabled Nokia 810 becomes more powerful and popular, the addition of Qt and simplified cross-compiling could provide a huge increase of third-party applications hosted on an already open mobile device.

Nifty Nokia

I'm really enjoying the n770. I'm definitely putting an n810 on my wishlist for the end of this year.

First thing I did was re-flash the device with OS 2007 Hacker Edition, an OS intended for the n800 but crammed into n770 hardware. It works rather well, only occasional reboots, but then again I'm working with a heavily used and refurbished unit. Who knows if it's the OS or the device. Google Talk, contacts, Bluetooth, 802.11b/g, a stripped-down mozilla engine and MPEG4 playback all works well.

I turned my lil' Nokia into a pocket translator with the Google Talk translator bot - the streamlined chat interface of OS 2007 turned the Nokia into a very handy (and quick) translation service.

Also tried to crack a test WRT54G router I have laying around using Aircrack, but I couldn't inject wifi packets using the OS 2007 wireless drivers so had to resort to the slower WEP cracking that needs a fair amount of seed traffic. It was still neat to browse all surrounding AP's on a full-screen xterm. With the n770's fantastic resolution, even the small typeface was definitely readable.

Also been mowing through a number of third-party apps. There is a fantastic developer community around the device - their Sourceforge-like approach to the Maemo Garage and the extensbility of the platform has served the developer and user community well.

It took me a while to find out what type of video the n770 will natively accept. There are several good resources out there, such as Andrew Flegg's Perl script that easily transcodes video into a n770-digestible format. The wide screen and nice resolution make mobile video much more palatable. The only caveat was that newer releases of MPlayer tag video with a newer but much less understood "FMP4" codec tag which OS2007HE doesn't understand. I had to tweak the script to pass the value "DX50" to the ffourcc option in order for the built-in media player to recognize the MPEG4 codec used. I also had to make sure encoding only happens at 15 frames per second, otherwise audio quickly gets out of sync.

When I get a free second I'm going to try getting some OpenVPN binaries to work as well. Would be very nifty to have an SSH stack and VPN access wherever I go.

Got Flash 9 somewhat working, although sound doesn't appear to work. Not a deal breaker tho, considering I'm working on a refurbished device running an unsupported OS meant for an entirely different hardware platform.

All in all, I'm a pretty happy gopher. Not sure what that means, but I am.

A Rite of Passage

I purchased a well used Nokia n770 Web tablet from a friend last month and, as tradition dictates, I must christen the device by authoring an entire blog post using only said device.
It really is a sweet little device... and since it runs a Debian-derived distro I can do pretty much anything I want with it. From checking e-mail to WEP cracking it runs the gambit.
The screen is positively beautiful. Video on this thing makes me giddy. Plus I have more connectivity options than I can shake a stick at.
I can totally understand why the n800 has the following it does now.

Nokia Acquires Trolltech & Qt

Trolltech, maker of my favorite development platform Qt 4, just announced they're being purchased by Nokia. Damn.

History has pretty much shown that the independent, open-source shops being purchased by mega-corps have largely resulted in a slovenly product. Novell's purchase of SuSE has resulted in a distro that kernel dumps... kernel dumps occasionally on bootup. I don't hold fantastic hopes for Qt 4 unfortunately.

It appears that others share my scepticism. A good deal of comments to LWN - which still boasts a pretty coherent readership - seems to also have the sort of timidity stemming from being burned before. The Register, which prints an overall positive article, still feels it needs to assert Nokia has made claims of continuing Qt development.

It feels at the same time like the OSS world is shrinking and expanding. While awareness and adoption is at an all-time high, the high-profile projects are starting to be absorbed into the same machine they raged against.
