The Mac Mini is Apple's smallest Mac and though it can be used as a workstation, it's often used as a server for offices/workgroups and even in datacentres. Apple even supplies software to make it function as a server (unsurprisingly called OS X Server - currently v5.0.15 is the release version and the beta variety v5.1 beta 2).

The server software supports various functions including a mail server and even remote Xcode compilations. However sometimes it's useful to remotely access the Mac Mini using Apple's remote desktop so getting a virtual screen on to the unit itself. Unfortunately if it's in headless mode, the on-board GPU is not enabled and all graphics is handled by the main CPU, which can make the system seems extremely slow as the CPU is spending it's time rendering the screen, animations and doing screen refreshes etc.

Now there is a solution to this and Newertechnology have produced an HDMI Headless Video Accelerator (t's about the same size as a small Bluetooth or WiFi adapter) that is plugged into the HDMI port and then the Mac Mini then thinks a screen is attached and thus the GPU is enabled meaning all screen handling is done by the GPU rather than the host CPU and everything runs smoothly again.

The adapter supports a maximum resolution of 1080p (and up to 3840 x 2160 on a late 2014 model). Other models supported are Mid 2010 through to the latest. OS X 10.6.8 is the earliest version of the operating supported (no drivers are required).

It can be found on-line for around £21.99. A really useful little edition if using a Mac Mini in headless mode and accessing it remotely (it's also true for using it for remote animation and anything that uses the GPU).

Techstars has opened applications for their 5th London program which will run from June 20th with the demo day taking place in September.

They will be accepting 10 to 12 teams and interested companies should apply on-line through F6s.

Techstars has some great mentors (there may be some bias here) and some great companies have come out of the program. It's progressed a lot since Springboard days.

Ofcom, the Super Regulator, (in December) published the new regulations for TV Whitespace technology which came into force on the 31st December 2015 allowing equipment that meets the regulations to operate on a license exempt basis.

In the new digital era of terrestrial TV, there are digital multiplexes across the UK, these multiplexes use different channels, so neighbouring transmitters don't interfere with each other, which means there is a lot of potentially unused spectrum in a particular area. Multiplex sit in the UHF band which covers 470 - 790 MHz.

In order to avoid interference with existing (licensed) spectrum users, devices will need to communicate with databases which apply rules, set by Ofcom, to put limits on the power levels and frequencies at which devices can operate. There is also a 'kill switch' function whereby the database can tell a device to stop operating completely if interference is found to be occurring.

The UHF TV band is currently allocated for use by Digital Terrestrial Television (DTT) broadcasting and Programme Making and Special Events (PMSE). Currently, Freeview TV channels are broadcast using up to ten multiplexes. Each multiplex requires an 8 MHz channel. Multiplexes are transmitted at different frequency channels across the country in the frequency range 470 to 790MHz.

Whilst a total of 32 channels each 8 MHz wide are reserved for DTT in the UK, normally only one channel per multiplex is used at any given location. In other words, the majority of channels are unused for DTT transmission at any given location. This is required because high-power TV broadcasts using the same frequency need geographic separation between their coverage areas to avoid interference.

The channels that are not used by DTT at any given location can be used by lower- power devices on an opportunistic basis. This opportunistic access to interleaved spectrum is not new. Programme making and special events (PMSE) equipment such as radio microphones and audio devices have been exploiting the interleaved spectrum for a number of years, and Ofcom issues more than 50,000 assignments annually for this type of use.

Ofcom refer to the spectrum that is left over by DTT (including local TV) and PMSE use as TV White Spaces (TVWS). By this we mean the combination of locations and frequencies in the UHF TV band that can be used by new users, operating in accordance with technical parameters that ensure that there is a low probability of harmful interference to DTT reception, PMSE usage or services above and below the band.

The following organisations have signed contracts and completed qualification to run the white space databases (WSDB): -

• Fairspectrum Oy
• Nominet UK
• Sony Europe Limited
• Spectrum Bridge Incorporated

The 'master' devices that talk to the databases should report their height, if they don't the database will use a use conservative default values for the purpose of calculation of operational parameters i.e. it will use height values that would result in operational parameters that are equal or more restrictive than they would be had the device reported its height.

Though the regulations do not specify an update time (for master devices to communicate to the databases), Ofcom has stated a maximum time of 15 minutes which strikes an appropriate balance between the need to be able to act quickly in the event of interference and limiting the practical burden on databases of maintaining frequent communications with potentially large numbers of devices. This may be revised if found to be unsuitable.

The WSD Regulations apply to the United Kingdom and the Isle of Man. They do not extend to the Channel Islands.

A master device is a device which is capable of communicating with and obtaining operational parameters from a database for the purpose of transmitting within the frequency band 470 MHz to 790 MHz.

A slave device is a device which is capable of transmitting within the frequency band 470 MHz to 790 MHz after receiving slave operational parameters from a master device.

Type A equipment as equipment which has an integral antenna, a dedicated antenna or an external antenna11 and is intended for fixed location use only.

Type B equipment as equipment which has a dedicated antenna or an integral antenna and is not intended for fixed location use.

WSDs must not be used airborne.

WSDs must be configured in such a way that a user is unable to input, reconfigure or alter any technical or operational settings or features of a device in a way which (i) would alter the technical characteristics of the device which are communicated to a database (this includes the master and slave device characteristics), or (ii) would cause the device to operate other than in accordance with master operational parameters or slave operational parameters, as applicable. An example of (ii) would be the antenna gain. If this parameter is set to be smaller than the actual gain of the antenna, then the device could radiate at a higher level than the limit communicated by the WSDB.

A master device:

• must be able to determine its location
• must provide device parameters (defined now as its ‘master device characteristics’) to a database, in order to obtain operational parameters from the database. The device parameters include the location and the technical characteristics of the device listed below. The operational parameters indicate to the device the channels and power levels that it can use, together with other constraints.
• must only transmit in the UHF TV band after requesting and receiving operational parameters from, and in accordance with, operational parameters provided by a database
• must apply the simultaneous operation power restriction (described at paragraph 3.23 above), if it operates on more than one DTT channel simultaneously and the master operational parameters indicate that this restriction applies
• must report back to the database the channels and powers that the WSD intends to use – the channel usage parameters – and operate within those channels and powers.

In addition, where its operational parameters stop being valid, a master device must tell slave devices that are connected to it to stop transmitting and must stop transmitting itself. The operational parameters stop being valid if:

• a database instructs the master device that the parameters are not valid
• a master device cannot verify, according to the update procedure, that the operational parameters are valid.

In order to support more WSDBs Ofcom also intend to publish on our website a machine-readable version of that list on a website hosted by Ofcom so that it can be selected by a WSD through a process known as “database discovery”. Ofcom would expect that list to include those database operators which have informed Ofcom that they are ready to start providing services to white space devices.

It is interesting that Sony is moving into this space, which probably means they will start producing equipment that uses white space technology for short range communication, such as say a PS4 to its peripherals.

The Intel Edison is a small system-on-chip (SoC) that measures about 35.5 × 25.0 × 3.9 mm (on its carrier PCB) which has a connector on it allowing it to be plugged into other things (it is possible to get the SoC on just the PCB without the edge connector).

The SoC board can then be plugged on to various boards from Intel, one is a breakout board which exposes various pins and has some USB sockets, there's also an Arduino compatible PCB allowing Arduino shields to be used.

The Edison tries to be everything to everyone, but doesn't always succeed. It actually has two processors inside, a dual thread dual core Atom running at 500MHz and a Quark 32 bit micro-controller running at 100MHz. The Atom runs Yocto Linux and the Quark a Real-time Operating System (RTOS).

It has 1GB of RAM and 4GB of Flash, 802.11 a/b/g/n WiFi and Bluetooth 4.0

There's a total of 40 I/O pins that can be configured to be: -

• SD card - 1 interface
• UART - 2 controllers, 1 with full flow control
• I2C - 2 controllers
• SPI - 1 controller with 2 chip selects
• I2S - 1 controller
• GPIO - 12 with 4 capable of PWM
• USB 2.0 - 1 OTG controller
• Clock output - 32 kHz, 19.2 MHz

Intel provide multiple ways of programming the system: -

• Arduino IDE (v1.6+, no longer requires an Intel specific build)
• Eclipse supporting: C, C++, and Python
• Intel XDK supporting: Node.JS and HTML5

There are other environments that also support Edison (in Arduino or direct mode) such as the node.js Johnny-Five system. Node-red can also be installed directly on the Edison and accessed through its web server. Google's Brillo is also an option now.

Running Linux does have benefits if you're into Linux environments as there's lots of packages that can be downloaded for it or indeed built as required.

You'll either love or hate Intel's development environment (XDK).

Integrating Edison into your own projects does give you a lot of flexibility, though the power requirements aren't as low as some other Arduino types (but by the time shields have been added to give the same functionality, power requirements increase with them). In theory it is possible to put the Atom to sleep and have the Quark micro controller do background non CPU intensive tasks and then it can wake the Atom up to do some hard processing or data transfers through WiFi say, but it's not meant to be 'easy' to actually implement.

The basic Edison (just the board) is around £42, on the small breakout board it's about £72 and on the Arduino base it's £96 though on-line pricing varies.

Overall the Edison really does tries to be everything to everyone and it's a pretty powerful computer (well 2), but it may be too generic for lots of things and the variety of programming modes etc can be confusing.

Just like Fahrvergnugen and Drivers Wanted, the days of Volkswagen's "Das Auto" campaign slogan has reached its end. It is one of the first casualties of the Dieselgate scandal that rocked Volkswagen in the last half of 2015.

A VW spokesperson from Germany has said that "Das Auto" will no longer accompany the brand's logo and will be phased out across the world.

Simply meaning The Car, Das Auto showed up in 2007 under then VW boss Martin Winterkorn's plan to make Volkswagen Group the number one auto manufacturer in the world. It summed up the company at that time. Ambitious, focused on alternative powertrain development like diesel and hybrid-electric vehicles. Das Auto now seems "pretentious" in the shadow of an uncertain future for one of the worlds best know auto makers.

So what does the future hold?  A surge of management changes and PR hires have been on going at VW and it is said that at a recent group management meeting that the group's core focus is to now shift to all efforts of fixing Volkswagen.

Rumors have been flying for a while now that Buick might be bringing wagon variant to the market. According to AutoGuide magazine, a trademark filing on December 16th by General Motors the names "Regal Tourx" and "Tourx" were secured. Now what does this mean? Perhaps nothing, but perhaps it could mean that GM is looking at the prospect of bringing the Opel Insignia Sports Tourer to the U.S. market from Europe.

The Insignia is the European vehicle which the Buick Regal is based off of. And naturally a wagon version is sold across the pond. The Regal is also one of Buick's top nameplates in the U.S. so this would be a natural progression to expand the lineup.

Now if we could have one in GS trim...

Socksy held their relaunch party last night at the Groucho club in Soho.

Socksy is a socks as a service company (SaaS), you sign-up and then get 3 pairs of high quality socks (street, neat or chic) delivered to your door every three months. They come in an A4 box so it will fit through your letterbox and the box can then be used to file papers etc.

The socks are all high quality and though the preferred Socksy method is for the subscriptions, it's also possible to buy them individually.

Socksy Mens' socks are generally knee length which takes a bit of getting used to if your used to wearing ankle length socks, but they're meant to be the 'real deal' and they're not socks if not knee length. Who knew?

If anyone wants to use the service there a 25% discount off the normal £60 per month service, by using code "lucky feet" (without quotes) the subscription fee is reduced to £45 every 3 months, so that's 3 pairs of high quality socks i.e. £15 a pair.

Socksy are also on Twitter , Facebook, Instagram and Tumblr.

A while back I started what I knew would be the first of my articles on the cars that have shaped me as an automobile enthusiast over the years. For part two, we are taking a look at a car that still to this day resides in my memory as one of the most pivotal unicorns in my life. The year was 1993. I was eleven years old at the time and just going in to middle school. The car that many like myself were lusting after was the Chevrolet Corvette. My dad had recently had and sold his 1987 Corvette coupe when we first heard about the 40th Anniversary Edition Corvette for the 1993 model year on our recent trip to the Corvette assembly plant in Bowling Green, Kentucky. This set my dad off on a search to find one for himself. I still remember the day. It was a Saturday not too far from Christmas when he found a 40th AE coupe at a dealer about an hour away from Pittsburgh.

There sitting on the showroom floor of Kenny Ross Chevrolet in Irwin, PA sat what would become his ruby red 40th AE coupe with a red bow on the hood. It was your pretty standard Corvette coupe. Equipped with preferred equipment group #1, the 40th AE appearance package, a bronze roof panel, Delco/Bose stereo and low tire pressure warning system. For a grand total of $39,304. My how times have changed in Corvette pricing. I do remember us driving the car home that following Monday and it spending much of the winter in the garage. When spring came the car saw lots of use for tours and just general fun drives and to go to a few car events. Being the 40th anniversary of the Corvette we collected as much memorabilia as we could find showcasing the the anniversary edition cars.




I don't remember why, but one day the paint on the corner of the rear bumper failed and started to flake off. Leading to the bumper being repaired by GM. This was the only fault with the car we ever had. My dad's best friend Lou even went and purchased a black Corvette coupe to go on drives with us. Even his car still sticks in my memory as it was the first Corvette I had ever seen with a cloth interior. Then tragedy hit the family. In the early spring of 1994 my father was diagnosed with a brain tumor. It was a whirlwind time that I don't remember a whole lot of. As the time for his operation came closer and he was getting everything in order for a worst case scenario. My father sold his Mercedes 300E sedan and the Corvette. Keeping just my mom's Mercedes and the 1972 Volkswagen that he shared with me. Wanting me to have "My" Beetle as a lasting memory (I will write of this car soon).

Again on a Saturday I remember riding in the Corvette one last time as we drove to Leopardi Auto Sales in Pittsburgh, a specialty used car dealer who agreed to purchase the Corvette. That was the last time I saw the car. I think maybe once we drove by and saw the car sitting on their showroom floor, but outside of that other 40th Anniversary Corvettes have come and gone. Occasionally seeing one or two at a show or on the street. The car always ingrained in my memory in sparkling Ruby Red. My dad survived the operation and the tumor was successfully removed. And other Corvettes have come and gone through the garage, but the 1993 40th Anniversary still lives in our memories as the one that got away that we still wish we had.

Why this car? What makes the 40th Anniversary Edition so special? Well obviously 1993 marked the 40th anniversary of Corvette production. To mark the occasion, Chevrolet produced 6,749 40th Anniversary Editions. An appearance package that cost $1,455. over the cost of a standard Corvette and was available on all trim levels. Coupe, convertible and ZR1. Each car was painted in Ruby Red Metallic with matching ruby red leather interiors, with convertibles receiving matching ruby red tops. The cars were then equipped with power passenger seats, sport bucket seat trim, special seat embroidery, Ruby Red inserts for the wheel center caps and chrome emblems. Each car could then be equipped with the line up of Corvette options. While many Corvettes today are called 40th Anniversary Editions by owners, only Ruby Red cars are the true special editions. This is, in part due to an error by GM's supplier where all Corvette seat upholstery had the special 40th Anniversary logo.  Otherwise, the cars were still powered by the 5.7 liter V8 (sans ZR1) and equipped to with either automatic or 6 speed manual transmissions.

Here's where you can help. I have been searching for my dad's 40th for several years now. We had retained the original window sticker for the car which now hangs in my office and has led me from time to time to search for it. I came close about 5 years ago when I googled the vin # and turned up an eBay auction that had been over for about two weeks. I made several attempts to contact the seller with no response. At the time the car was in Indiana and showed just over 30,000 miles. I know the car was sold to Michigan through my follow up searches. Last registrations show somewhere around Kalamazoo. I would love to surprise my dad by buying him back his pride and joy. I could got get just any 40th AE, but it's not the same. I am desperately trying to find 1993 Chevrolet Corvette vin # 1G1YY23P5P5119264. Please help me bring this car home. Below is the most recent picture I have of the car from the eBay auction. Please, if you can help track down the current owner of the car I would be extremely grateful.

nCube is a home hub that connects to your home network and then allows you to control devices in your home through the nCube app.

It works with lots of home devices such as Nest thermostat, Philips Hue and LIFX lights, sonos music and Belkin WeMo plug-in & lightbulb products.

Protocols supported are WiFI, Bluetooth and Z-Wave.

The device is secure (the phone app must be set-up on the home network) and the nCube device uses a VPN into the nCube cloud services.

As well as being functional the nCube app is designed to be easy to use and has won several design awards.

The nCube Kickstarter campaign finishes in 3 days so get backing, it's still possible to get one for an early bird price of £99 (it will retail for £139).

Ofcom, the Super Regulator, is holding a consultation on Licence Exemption of Wireless Telegraphy Devices.

Walkie Talkies or as they're officially known as Private Mobile Radio (PMR), are allowed to operate in license exempt status in the band 446.0 - 446.2 MHz. Previously this was split into to bands, 446.0 - 446.1 MHz for Analogue PMR446 equipment and 446.1 - 446.2 MHz for Digital PMR446 equipment.

Ofcom is proposing to make the whole band available for both analogue and digital PMR446 equipment, whereby: -

• the band 446.0-446.2 MHz for the use of analogue PMR 446 with a channel plan based on 12.5 kHz spacing where the lowest carrier frequency is 446.00625 MHz
• the band 446.1-446.2 MHz for the use of digital PMR 446 with a channel plan based on 6.25 kHz and 12.5 kHz spacing where the lowest carrier frequencies are 446,103125 MHz and 446.10625 MHz respectively
• the band 446.0-446.2 MHz for the use of digital PMR 446 with a channel plan based on 6.25 kHz and 12.5 kHz spacing where the lowest carrier frequencies are 446,003125 MHz and 446.00625 MHz respectively as of 1 January 2018
• analogue PMR446 equipment operating in the frequency range 446.1-446.2 MHz should use more robust receivers as specified in ETSI TS 103 236 or equivalent technical specifications

This would allow any device to transmit max 500mW while NO fixed basestations are allowed and the maximum transmit time would be 180s, This would all come into effect in Jan 2018.

Ofcom also wish to change mandated exclusion zones around radio astronomy sites for level crossing radar to that of co-ordinated exclusion zones i.e. level crossing radar in the exclusions zones could be used with the coordination of the Radio Astronomy sites. The methodology, decision and appeal processes to determine whether a device can be deployed in the coordination zone is to be agreed between the rail network operators and the Radio Astronomy service.

The current exclusion zones are

Site	NGR	Exclusion zone
Jodrell Bank	SJ 79650 50950	20 km
Cambridge	TL 39400 54000	20 km
Defford	SO 90200 44700	20 km
Darnhall	SJ 64275 62265	20 km
Knockin	SJ 32855 21880	20 km
Pickmere	SJ 70404 76945	20 km

DECT equipment has been license exempt for a number of years, operating in the band 1880 to 1900 MHz. Currently the document exempting the equipment states that a handset connects to a basestation and it is proposed to just change the to a short range device (SRD) to make it more applicable to handsets that aren't connected to the telephone network.

Stakeholders wishing to respond may do so using Ofcom's on-line form.

Misfit have produced the prettiest wearable for a while, the original Shine tracked steps and was one (if not the) first to do automatic sleep tracking. It was a small disk (27.5mm across and 3.3mm high) which contained the electronics and a changeable CR2032 coin cell which lasted for about 6 months. It came with a silicon strap and a silicon magnetic clip so it could be worn on the wrist or clipped on to a t-shirt, bra, shoes, trouser pocket or wherever suited the user. It's also possible to buy socks and t-shirts with a dedicated Shine pocket and a necklace too. It links back to the Misfit app (Android and iOS) using Bluetooth 4.0.

Now the Shine2 is out it's bigger (it's 30.5mm across and 8mm height) and comes in matt black (carbon back as Misfit describe it) and rose gold. It's also 50m water resistant. The original Shine had 12 white LEDs around the edge and the have been upgraded to RGB LEDs, there's also a 'buzzer' inside that can notify you of various things. The battery is still a CR2032 which should last for around 6 months and Bluetooth is now 4.1 which allows for faster data transfers.

The Shine2 can now wake you up by its buzzer (you set the time in the app), the original Shine had the smart alarm feature, but you'd need the phone by your side. It can now also notify you of calls and texts.

The strap and clip unfortunately don't feel as well made as the smaller ones with the original Shine, but then there'll probably be a slew of new accessories for you to spend more money with Misfit.

Having used the Shine2 for a day, sync'ing definitely seems faster, though you definitely notice the size increase.

Still a very pretty wearable compared to most.

It retails for $99.99 from the Misfit Store (they do ship to the UK using DHL so add shipping costs and import duties/VAT).

Ofcom, the Super regular has published a report on how it has worked with Haringey Council to remove equipment used for Pirate Radio broadcasting from buildings operated by the council. 19 stations were closed in 2014.

Ofcom and Haringey estimate that this has saved the council £90,000 in enforcement and maintenance costs. Ofcom is meeting with other councils on the 3rd of November to report their findings from the Haringey cooperation and if this is rolled out across London could save councils £1m per annum.

Though Pirate radio is illegal it can form a basis for community radio, unfortunately it can cause real issues and NATS has reported 55 incidents of interference from Pirate station. There have also been complaints from emergency services and licensed commercial users.

There are schemes in place for local broadcasters to legally broadcast and Ofcom has even allowed DAB stations to be set-up using off-the-shelf hardware and open source software which means a DAB station can be set-up for around £6,000. These use Linux and efforts from OpenDigitalRadio and commercially available software defined radios.

Pirate radio has been groundbreaking in the past and it will be a shame if all Pirate radio stations disappear, but if Ofcom genuinely allow more open access using local commercial DAB multiplexes maybe it won't matter.
