Apple Watch And The Danger Of Undocumented Features

Maybe, maybe not. 

Turns out that the Apple Watch has a secret hiding in its developer port, which itself is hidden in the attachment point for the Watch's bands. It is possible to charger via a physical connection, as well as the Qi connection on the rear plate.

This opens up all kinds of possibilities for bands with batteries or charging connections exposed to the outside world. One watch band manufacturer - Reserve, discoverer of the capability - intends to rejig its planned battery band to use the port.

Now, placing the port where it is on the Watch strongly suggests that Apple may have had this in mind for a future development. Or may have had it in mind for launch and decided to cancel the feature at the last moment. Whatever the truth basing a project on an undocumented feature which could be disabled by Apple through software doesn't strike me as a particularly clever thing to do.

Not that I think it represents a risk to the Watch itself, but if the Reserve were to prove successful and then Apple were to throw the kill-switch the company would saddle itself with a heap of disgruntled customers, a possible barrel-load of returned hardware and a damaged brand.

On the other hand if Apple are planning on allowing this port to be used for charging then you can be sure that it will want to vet products to ensure they aren't going to damage a customer's Watch. This suggests that a certification programme, along the lines of MFi, could be in the offing. Whether this will be backed with DRM remains to be seen.

In either case I'd tread very carefully before buying the Reserve, because you may end up with a pointlessly heavy watch strap that doesn't do what you bought it for.

F1: Robert Kubica Impresses In Renault Test Run

The car may be old but its the performance of the driver that's the story here. Robert Kubica returned to F1, after a fashion, earlier this week with an extensive test run in a 2012 Lotus Renault F1 car at Valencia.
The age of the car and the circuit were likely determined by F1's current rules which ban testing, but the reason for Kubica being in the car is far more interesting. Considered by many to be a potential World Champion and certainly one of the fastest drivers of his generation, Kubica's F1 career seemed to be over after a 2011 crash whilst driving in the Rally of Andora. His Skoda Fabia was penetrated by a guardrail in the high speed accident partially severing his right arm.
Up until last year Kubica has been competing in rallying, with the expectation that the limited movement in his repaired arm would prohibit a return to single seater racing.
So this week's test is both interesting and confusing. Interesting because Kubica completed 115 laps of the ret…

F1: Robert Kubica's Williams Test Asks More Questions Than It Answers

Comparing driver's times at a tyre evaluation test like last week's Abu Dhabi event is difficult at the best of times, but when trying to assess the performance of a driver who has been out of the sport for six years, that difficulty level is raised even higher.
On the face of it Robert Kubica's test for Williams was a success. Fastest of the three Williams drivers present the headlines look promising. However, taking into consideration the different tyres used to set those times muddies the water considerably.
Kubica ran a three lap qualifying simulation on the new 'hyper-soft' tyre - which should have given him a two-second advantage. Correcting for tyres it would appear that Kubica was significantly slower than Sergei Sorotkin - who was on the harder 'soft' tyre - and marginally quicker than Lance Stroll, the team's only contracted driver.

Stroll's family fortune currently funds Williams, so there' no chance that he will be anywhere but in a…

Panos Panay's Defence Of Microsoft Surface Hardware Sounds Eerily Familiar

This weekend I went out with my ten year old daughter to select a laptop for her school year beginning in January. The schools requirements are quite specific, requiring a Windows 10 device, with a preference for a touchscreen and a stylus. She chose a Surface Pro, after trying a large number of different options. Having seen the way I use my own Surface Pro - and tried it herself there was only ever going to be two options - and the other was a Surface Laptop.
I tell you this so that you understand I am a buyer of Microsoft's products through choice, not compulsion. I'm on my third Surface device now. 
So when Panos Panay dismissed reports of the death of the Surface hardware line, I was very interested to see exactly how strong these denials were. Especially how they reflect what has gone before. To whit: Windows 10 Mobile.
Panay claimed that Microsoft is in hardware for the long haul. Almost exactly mirroring the words of Terry Myerson, when he claimed Windows Mobile was g…
