Submission + - RIM's future hangs on developer support for "new BlackBerry" (networkworld.com)

alphadogg writes: With its future up for grabs, Research in Motion at its annual BlackBerry World conference next week will focus on simplifying development for its soon-to-be-unveiled BlackBerry 10 operating system. HTML5 is one key technology in that strategy to create a viable ecosystem of applications for a new generation of mobile devices expected to ship by year-end. The simplicity is needed because BB10, based on a real time kernel acquired with RIM's buyout of QNX Software Systems in 2010, is a complete break with the software that runs on standard BlackBerry smartphones. "It's a bit of a challenge," says Tyler Lessard, formerly a RIM vice president in charge of the global developer program, and since October 2011 chief marketing officer at mobile security vendor Fixmo. "There's very little or no compatibility between the old and new operating systems. Existing apps can't be carried forward to QNX and BB 10. The question is, once the BlackBerry 10 smartphones launch, can RIM have an adequate catalog of apps?"

Submission + - Optus loses second battle in Aussie TV-timeshifting battle (abc.net.au)

beaverdownunder writes: After winning an initial legal battle to continue its mobile TV Now terrestrial-television re-broadcasting service, Optus has lost a second battle in Australian Federal court. The Optus system 'time-shifted' broadcast signals by two minutes, and then streamed them to customers' mobile phones.

In the previous ruling, the judge sided with Optus' argument that since the customer requested the service, they were the ones recording the signal, and thus was fair-use under Australian copyright law. However, the new ruling had declared Optus to be the true entity recording and re-distributing the broadcasts, and thus is in violation of the law.

There has been no word yet on whether Optus will appeal the decision, but as they could be retroactively liable for a great deal of damages, it is almost certain that they will.

The Japanese have been very successful in curbing demand. I was over in Japan for a week on a business trip last year, and it was interesting to see how they did it. This included absolutely all hand-driers in toilets being switched off, less air-conditioning (room temperature was set for 28C in the office), the business week of large corporations shifted to reduce peak-week-time demand and increase that on the weekend, and a move to more relaxed corporate dress-code - which included in many cases, a small towel attached to the waistband with which to mop off the sweat form the oppressive environment. There were no doubt more measures that I wasn't aware of, but life definitely carries on as normal without power cuts.

Our suspicion is that this state of affairs will become the norm.

I think the point here is that whilst applications do indeed have access, this is often mediated through Apple's user-interface in each case - which I suspect you'll find is actually provided by another process within a different sandbox. This means that rogue applications are not hoovering up your data without user-interaction.

In iOS, applications don't have a lot of access to personal data to start with - and certainly not to read SMS (although apps can send using an Apple sanction UI only). They do have access to the contents of the address book, but this is looks likely to change soon.

The proposals for the UK go further: registration of scrap metal dealers and banning of cash payments for scrap, thereby also eliminating huge amounts of tax fraud.

A rather unsavoury fact is that a lot metal theft is perpetrated by employees taking surplus or redundant materials from the employer.

Having implemented just such an application (it has a large model layer shared with the iPad version of the same app), this is not a trivial bit of engineering.
JNI provides lots of ways to screw up and debugging across the interface is challenging to say the least.

By FAR the best way to do the development is to get the model and JNI portions working and thoroughly unit tested with a test-harness before going anywhere near any of Google's tools or a device. Since lots of your problems are going to be in C/C++ land, invoking a JVM from native code makes life a lot easier at this stage.

An easy port it was not.

With the possible scenario of Windows Phone 7 being the 3rd successful mobile platform, building the bottom layers of these apps in C#/.Net is looking quite attractive as you can run it on all of the platforms. I assume MonoDroid deals with the consequential .NET VM Native Java boundary crossing.

Clock recovery with firewire audio streams is already pretty damn accurate - and it's entirely possible to achieve sample-accurate presentation. Yamaha's mLAN chipsets had this capability, and I suspect TC's DICE family of devices can too.

Also, extremely low latency is achievable. I can't remember the precise numbers at this juncture, but the limiting factor is the latency hit of a short bus reset. Winding latency down to a couple of milliseconds in each direction is doable.

The limiting factor tends to be the software generating or consuming the audio stream - in practice this usually involves a couple of real-time threads getting woken up perhaps every millisecond to work on a small amount of data - which invariably involves a read, modify (e.g. DSP of some kind) and then write somewhere else - possibly with interleaving for large channels counts.. This starts looking like a pathologically cache-ineffecient workload that doesn't improve much as CPUs get faster.

This will be interesting to watch: whilst for applications such as storage and HD cameras, IEEE1394 isn't cutting it any more, it's more than adequate for music production applications, and Thunderbolt will do nothing but add cost to these devices. The acid test will be Apple dropping the FW S-800 port off their products.

Sure - there's plenty of investment in both off-shore and on-shore wind generation in the UK (this gives a pretty good idea of the scale), but it doesn't change the fact that wind power cannot at present - in lieu of radical developments in energy storage, or demand modulation - provide reliable base-load. Wind-farms - even when offshore generate plenty of objections.

It's disappointing that there have not been more offshore tidal energy schemes, since these could be an entirely reliable energy source. The usual excuse offered is that whilst there are plenty of prototype devices, none of them are considered mature enough for large-scale investment.

Rather than increasing the amount of nuclear energy the in the UK, the proposed reactors are replacements for existing nuclear generation capacity that is reaching the end its life. What is perhaps interesting is that economics are starting to look very favourable for Nuclear generation right now - renewable generation is not cheap.
