RunRev releases LiveCode for Android preview alongside iOS, Mac, Windows, Linux

RunRev has announced a preview version of its LiveCode for Google Android, which will join existing versions for Windows, Mac, Linux, Web and iOS.

LiveCode is like a modern-day HyperCard, an early database and simple application builder for the Mac. It includes a graphical development environment with scripting using the LiveCode language, described by RunRev as “A very high level language”. Here is a sample:

put “The fox jumped over the lazy dog.” into theText

put “ quick brown” after word 2 of theText

The advantage is fast development, once you have become familiar with the platform.

On a quick look I noticed that LiveCode looks great for building a business-oriented client, but looks more challenging when it comes to interacting with a remote server application, though it does have support for basic http and https requests as well as socket support.

Now that Android is supported LiveCode looks interesting as a quick and easy route to cross-platform mobile apps.

Mobile app developers can register to receive the Android pre-release version today at www.runrev.com.

Computer book stats show resilience of Java as Android booms

3 Comments

Mike Hendrickson at O’Reilly has posted four articles analysing the state of the computer book market in more detail than most of us care about.  The overall picture is not too good – sales are down – and there are some interesting trends.

Here is a good one for anyone who thinks Java is dying. The programming languages post shows that unit sales of books on Java increased by 17.2% in 2010 vs 2009, whereas the next most popular language, C#, declined by 1.7%. Objective C, in third place, also declined slightly. JavaScript unit sales were up by 14.5%.

Why is Java booming? There is a clue in one of the two bestselling Java titles mentioned by Hendrickson: Professional Android 2 Application Development

Another trend that caught my eye is in the first post. Some of the Down categories surprised me:

Adobe Flash –84.43%

Mac OS –32.12%

Web Design Tools –53.2%

Adobe’s Creative Suite 5 has sold well as far as I’m aware so although books on Flash and Dreamweaver have not been selling well, it is dangerous to draw obvious conclusions.

The influence of Android is unmistakeable though. Something for Oracle to consider as it pursues Google for breach of intellectual property.

First look at HP’s TouchPad WebOS tablet

I took a close look at HP’s WebOS TouchPad tablet during Mobile World Congress in Barcelona.

This 9.7” machine looks delightful. One of its features is wireless charging using the optional Touchstone accessory. The same technology can also transmit data, as mentioned in this post on wireless charging, and the TouchPad makes use of this in conjunction with new WebOS smartphones such as the Pre3 and the Veer. Put one of these devices next to a TouchPad and the smartphone automatically navigates to the same URL that is displayed on the TouchPad. A gimmick, but a clever one.

image

From what I saw though, these WebOS devices are fast and smooth, with strong multitasking and a pleasant user interface. Wireless charging is excellent, and a feature you would expect Apple to adopt before long since it reduces clutter.

I still would not bet on HP winning big market share with WebOS. The original Palm Pre was released to rave reviews but disappointing sales, and HP will have to work a miracle to avoid the same fate.

Wireless power at Mobile World Congress: no more chargers?

At Mobile World Congress Fulton Innovation was showing off its wireless power technology called eCoupled. We are accustomed to the idea of transmitting data wirelessly, but less familiar with wireless power. It is possible though, and I saw several examples. One of the most striking but least useful is this cereal box, printed with conductive ink, which lights up when placed on a special shelf – the inset image shows the same packet before the title lit up.

image

The technology has plenty of potential though. I travelled to Barcelona with a case full of chargers, and the idea of simply placing them on a charging shelf instead is compelling; this is already possible and I saw several examples. The Wireless Power Consortium has created a wireless power standard called Qi:

It will be no surprise to see Qi stations in the office, hotels, airports, railway stations as part of the normal infrastructure that offers wireless power charging service

image

On the eCoupled site you can see some other ideas, like kitchen appliances that work simply by being placed on a powered surface:

eCoupled will one day integrate into the walls and surfaces of your home. If you’re watching the big game, the TV won’t need to be plugged in. Power will be delivered wirelessly via the eCoupled-enabled wall. In the kitchen, a multipurpose countertop will allow you to mix, chop, blend and boil all on the same powered surface. There will be no cords to plug in, or outlets to worry about.

The technology allows data transmission as well, so the glowing cereal box can also report when it has passed its sell-by date. Now that might actually serve a purpose.

Motorola Atrix – the future of the laptop?

1 Comment

I took a closer look at the Motorola Atrix on display here at Mobile World Congress. This is a smartphone built on NVidia’s Tegra 2 dual-core chipset. I’m interested in the concept as much as the device. Instead of carrying a laptop and a smartphone, you use the smartphone alone when out and about, or dock to a laptop-like screen and keyboard when at a desk. The dock has its own 36Wh battery so you are not tied to mains power.

image

image

image

The Atrix has a few extra tricks as well. HDMI out enables HD video. An audio dock converts it to a decent portable music player.

image

The smartphone also morphs into a controller if you use Motorola’s alternative dock, designed for fully external keyboard and screen.

image

It is a compelling concept, though there is a little awkwardness in the way Motorola has implemented it. The Atrix has two graphical shells installed. One is Android. The other is a an alternative Linux shell which Motorola calls Webtop. While you can freely download apps to Android, the Webtop has just a few applications pre-installed by Motorola, and with no official way to add further applications. One of them is Firefox, so you can browse the web using a full-size browser.

The disconnect between Android and Webtop is mitigated by the ability to run Android within Webtop, either in its own smartphone-sized window, or full screen.

Personally I prefer the idea of running Android full screen, even though it is not designed for a laptop-sized screen, as I do not like the idea of having two separate sets of apps. That seems to miss the point of having a single device. On the other hand, Webtop does enable non-Android apps to run on Atrix, so I can see the value it adds.

Leaving that aside, I do think this is a great idea and one that I expect to become important. After all, if you do not think  Tegra 2 is quite powerful enough, you could wait for some future version built on the quad-core Tegra 3 (name not yet confirmed), which NVidia says is five times faster, and which may turn up in Smartphones late in 2011.

Qualcomm: optimising for Windows Phone took years not months

I had a chat with Qualcomm’s Raj Talluri here at Mobile World Congress in Barcelona. Of course I asked about the Nokia-Microsoft deal and the implications for Qualcomm. Currently Microsoft specify Qualcomm’s Snapdragon as the required chipset for Windows Phone 7 devices: good for Qualcomm, not so good for Microsoft since it means competing system-on-a-chip vendors like TI and NVidia are putting all their efforts into Android or other mobile operating systems.

“We are extremely pleased and we are very optimistic that it will bring us additional business.” said Talluri about the Nokia-Microsoft alliance. That said, might Nokia in fact choose a competing chipset for its Windows Phone devices?

It might; but the issue here is the work involved in optimising the hardware and drivers for the OS:

If you look at Windows Phone, there’s a lot of custom work we did with Microsoft that makes Windows Phone 7 really shine on Snapdragon … the amount of time we spent in getting those things optimized, it’s been a multi-year effort for us.

If you put this together with Nokia’s announced intention to ship Windows Phone devices this year, it is hard to see how it could use a chipset other than Snapdragon.

That said, those other vendors might not agree that it would take years. When I asked about this, NVidia gave me the impression that it could do the work in a few months, if there was a business case for it.

Still, it is not a trivial matter, and adds potential for delay. I think we should expect Nokia’s first Windows phones to run Qualcomm chipsets.

If the Windows Phone ecosystem builds as Nokia hopes, other chipset vendors may get involved. Then again, what are Microsoft’s plans for the Windows Phone OS long-term? Might the underlying Windows CE OS get scrapped in favour of something coming out of the Windows on Arm project? Silverlight and XNA apps should port across easily.

That is a matter for speculation, but the possibility may deter other mobile chipset manufacturers from heavy investment in Windows Phone support.

NVidia: first mobile quad-core devices will be this year

Qualcomm was first to announce a quad-core mobile chipset here at Mobile World Congress in Barcelona – the Snapdragon APQ8064 – but NVidia says it will be first to market, with its quad-core successor to Tegra 2, code-named Kal-El. NVidia expects a Kal-El Android tablet to ship in August 2011, with smartphones to follow in the autumn. Qualcomm on the other hand says that samples of the APQ8064 are anticipated to be available in early 2012, implying that products will come later next year.

Kal-El is the successor to Tegra 2, and said to be 5 times faster. It also includes a 12-core GPU and supports HD video up to 12560×1600 – amazing for a low-power mobile chipset.

A prototype is running on NVidia’s stand here and while my snap does not show the quality, you will have to take my word that the graphics looked excellent.

The LG Optimus 3D is amazing

Today I got to see the LG Optimus 3D here at Mobile World Congress in Barcelona. I was impressed. Of course I cannot really capture it in a pic; but here it is anyway.

image

It really is 3D, which is amazing after a lifetime of 2D screens, and with no spectacles required.

The trick is that there are two screen images. When you look at the screen, your right eye gets a slightly different angle on the screen than your left eye. The technology uses that different angle to deliver a different image to each eye. At least, this is how it was explained to me.

There is also a dual-lens camera so you can take your own 3D pics and videos. The Optimus 3D has a 1GHz OMAP4 dual-core processor, and HDMI output for connection to high resolution external displays.

3D is cool and makes for some immersive games. But how much extra will customers be willing to pay for 3D on a Smartphone? Interesting question.

HTC’s new Android tablet has a stylus

A big surprise here at Mobile World Congress in Barcelona: HTC’s new tablet, the HTC Flyer, comes with a stylus. “People can rediscover the natural act of writing,” says the press release.

My first reaction is that this a mistake. I have had tablets with pens before, and while I like the ability to take notes, I also find the pen a nuisance. They are awkward in confined spaces like an economy seat in an aeroplane, and expensive to lose. HTC’s pen is battery powered, so I suppose you could also have the annoyance of a pen that runs out of juice. HTC’s stylus does not clip into a bay on the device, but does have a dedicated pocket in the case.

image

On the plus side, you can write, draw and annotate content using the pen, which has a variety of settings for colour and tip. For some tasks, a pen is the ideal implement.

image

The device does have other attractions. The pre-release devices have Android 2.4, but HTC says it may well run Android 3.0 “Honeycomb”, which is designed for tablets, by the time it is launched in Q2 2011 or soon after. It has a 1.5Ghz Qualcomm Snapdragon chipset; 7” screen; 1024 x 600 resolution; 1GB RAM and 32GB storage, expandable with micro SD cards. Battery is said provide 4 hours of video playback, which sounds less than ideal. HTC will also offer a video download service “HTC Watch”.

A feature which will be familiar to OneNote users is called Timemark. This lets you take notes which synch to an audio recording, so tapping a word in your notes takes you to that point in the audio. Notes also synchronize with Evernote, a cloud-based note synchronization service.
