Unobtainium and the Extinction of Technology

Intel 8742, As a youth I had a fairly respectable - for an amateur - electronic test equipment rig, and used to have all kinds of fun tinkering with radio and the like. But sadly as I grew older this gave way to make space for things erm, more grown up, such as records and computers. However for the last few years I’ve been pining to get some kit together again so that I can experiment and play once more, and this has been driven in part by an interest in GNU Radio. To this end I finally started to collect together bits of old test equipment, and recently spotted a HP RF signal generator on eBay. But before placing a bid I did a little research and came across a mildly humorous post in connection with failed attempts at repairing that model. I shouldn’t take pleasure in Ancient_Hacker’s pain, but I’ve had similar experiences in the past with other 70s/80s produced RF kit that is built like a tank and that is as temperamental as it is complex. I’ve been there, and appreciate what it feels like to spend hour upon hour working on fiddly perplexing equipment that leads you in circles and often brings about delirium.

The news group post was also the first time in a good while I’d heard the term unobtainium. And whilst as Wikipedia suggests this is a “humorous colloquialism” the ramifications of having equipment with broken parts deemed such are far from jolly. OK so in the aforementioned case this likely amounts to little more than an annoyance to electronics enthusiasts who are in possession of test equipment that most would deem obsolete. But unobtainium of the semiconductor variety is not limited to the hybrid circuits and obscure ECL of outmoded test equipment. And can be found for example in classic computing of the 60s and 70s, through to equipment of the 90s and possibly later. Sometimes taking the form of devices that are highly application specific - E.g. ASICs and hybrid circuits -, and at other times fairly primitive building blocks that find themselves in all manner of applications. E.g. I was surprised to learn recently that even certain 74 series logic is becoming impossible to obtain.

My concern is that whilst we are at last beginning to value our computing history - E.g. the UK recently gained a National Museum of Computing - has anyone given thought to preserving stocks of no longer produced semiconductor components, along with the associated design documentation and masks Etc? With vintage cars we can make pattern parts. We somehow appear to have an endless supply of new old stock valves/electron tubes for old radios and very old computers. In addition to which driven by the high-end hifi market companies in the East and Eastern Europe are producing modern clones of many valves. And whilst we also have things like seed libraries and providers of medical standards, I wonder if anyone has given thought to semiconductors. And to play devil’s advocate does it matter? Perhaps for an overwhelming majority it doesn’t and they would consider outmoded silicon of less significance than say an out of fashion or obscure vinyl record or CD. It does however seem sad that aspects of our electronics history might be lost and with this potentially novel ideas. And beyond which that in years to come we might have a great deal of classic computing equipment that at worst is capable of nothing, and at best has had large sections replaced by software emulation and implementations in FPGA.

The Language of FOSS

I think there are few who would deny that language is a powerful tool. And whilst in our social lives we may take care (or not!) with the language we use in various circumstances, at work in the Enterprise we are much more likely to pick up the local or latest dialect in an effort to be more easily understood, appear current or simply feel like we belong. This may sometimes be a good thing, and equally at other times it is not. A good example of the latter is with the vocabulary that the Enterprise is assembling around Free and Open Source Software (FOSS). This is being driven primarily by commercial interests who are seeking to monetise FOSS opportunities, who’s business models depend on an ability to solve some problem and one you might not even know you have yet!

I must admit that I myself have been guilty of breathing the exhaust of such vendors and it is easy to fall into this trap. But thankfully you don’t need to be a master NLP practitioner in order to be able to cut through what can range from mild spin to out-and-out FUD. All you need do is look a little wider afield and cast back to how FOSS worked before we had magic pixie dust sprinkled Enterprise FOSS.

One of the Enterprise’s favourite negative terms in connection with FOSS is “licensing issues”. Issues? I don’t see issues, only license obligations. I.e. In short FOSS is not a free-for-all and you either meet any obligations and respect the wishes of the author(s) of the code, else you have no license to use it. And if the terms don’t fit with your usage go look elsewhere. Simple and not an issue! This is no different to proprietary software either as this also comes with conditions for usage.

“Risks” associated with FOSS is another favourite, and the provision of support being one of the most common concerns cited. But in this respect FOSS is largely no different to proprietary technology and it is still just a matter of can you support it or do you have a contract with people that can? Beyond which FOSS through access to source provides an opportunity to multi-source support, thereby creating a competitive environment, driving costs down and removing reliance on a single vendor. Or you can for the first time ever do self-support, and you shouldn’t always assume that an external service provider will be blessed with God-like abilities. It may be that you could provide support in-house for a similar or even lower cost, and reap the benefits from having a deeper knowledge of the technology and influence it’s development through community engagement. So in this and many other respects FOSS presents new opportunities to the consumer as well as to vendors, often greatly reduces the risks on both sides and provides an unprecedented range of options. The only risk to be found here is one of missed opportunity brought about through a lack of understanding.

Another common complaint is the “viral” nature of the (L)GPL. The very word viral strikes fear into everyone ranging from developers to product managers and IPR attorneys. It is an unfortunate term that is often applied to one of the fundamental instruments of free software, that without which the continued freedom of such software could not be guaranteed. Ironically it is this feature of the (L)GPL that ensures that an Enterprise’s investment in free software is not misappropriated, and that the freedom they grant to licensees will be carried with the code as it evolves and is enhanced. It is this which prevents a 3rd party from taking their efforts, making modifications to the code and then selling this on as a closed binary-only version, possibly in direct competition.

These are just a few examples, there are others and more will come about as vendors of Enterprise software and services identify new revenue generating opportunities.

However there will be cases where new tools and services are required and this is to be expected. And it is true that the effective adoption of FOSS technology and principles in the Enterprise is dependent on appropriate governance. The game has changed and the Enterprise must adapt. But to secure it’s sanity moving forward it should look closely at how the FOSS ecosystem worked in the days prior to the invasion of the venture capitalists. It should not regard FOSS technology as alien code to be prodded with a stick and regarded with suspicion, but should measure it in the same ways it would proprietary software: Who made it and do I trust them? What does the license allow you to do and what are the obligations? Who supports it and and at what cost? The questions haven’t changed. Lastly and the crux of this post: the Enterprise needs to learn to filter out of it’s vocabulary the FOSS terminology that was inserted by vendors seeking a sale. Otherwise it can look forward to a future that is a self-fulfilling prophecy of “licensing issues” and “support risks”, with all the costs and inflexibility of proprietary software and few of the benefits of FOSS!

Lawrence Lessig SCL Lecture: Corruption 2.0

Recently Professor Lawrence Lessig famously declared the last ten years of his career a closed book. And stated that he intended to shift from working on free culture and matters pertaining to copyright and software patents, to the next major challenge he believes that technology must solve: Corruption 2.0. And so we were fortunate at the Society of Computers & Law’s lecture last week to be given a skilfully crafted introduction to this challenge by the engaging and entertaining Prof. Lessig himself.

He started by outlining a framework and asserting that computer code and legal code are very similar, both serve to either constrain or enable and often have an effect on each other. Together with society’s norms these three instruments come together to effect social control and dictate what we can and can’t do.

Next up we were treated to three stories, two of which originated from Jonathan Zittrain who has in a sense carried on where Prof. Lessig left off. One about privacy and copyright and how technology has destroyed control where it once enabled it. E.g. a traditional wiretap was expensive whereas a tap on Internet traffic is much cheaper, and vinyl LPs were expensive to duplicate but now the cost of music duplication is literally zero. The second Zittrain story was taken from his book The Future of the Internet–And How to Stop It. And suggested that because the modern personal computer will perform almost any task and the Internet will take us anywhere this leads to both good and bad outcomes. E.g. for $50K you can hire a botnet to attack an opponent’s online presence. With one possible method for mitigating the negative effects of generativity being the taxing of innovation, vendor control and dumbing down of devices E.g. Tivoization. The third story started out in praise of geeks and their desire to make the impossible possible, E.g. “arguing with God” as they advance the state of the art in semiconductor fabrication. And then went on to describe an experience when visiting Microsoft where he suggested to a room full of geeks that law may have a place in combating spam, alongside lines of computer code. A suggestion for which he was apparently ridiculed.

Following the three stories we were presented with a pathology, and Prof. Lessig explained how Corruption 1.0 was driven by interest. E.g. a US politician was once advised to “lean to the green”, that is to say go where the money is. And how when setting nutritional guidelines for sugar consumption the US administration set a level of 25% of total daily calorific intake, despite the World Health Organisation recommending a maximum of 10%. The former figure being preferred by the sugar industry, who apparently threatened to withdraw funding of certain activities if the administration went with the less industry friendly WHO figure.

Prof. Lessig also detailed the shift from what he termed a read-only (R/O) culture to a read-write (R/W) culture. So where we once consumed we now also create, and to be specific remix. We are no longer satiated as simply consumers, the media and the tools are within reach of most if not all and we want to express our creativity. Enter DJ Danger Mouse and the Grey Album and Johan Soderberg and his Bush/Blair love duet, to cite but two examples. Of course this rarely sits well with copyright laws, and goes as far as a woman receiving a cease and desist from Universal Music for posting on Youtube a video of her toddler dancing. Why? Because Prince was playing on the stereo in the background.

To get to the crux of the matter Prof. Lessig stated that whereas Corruption 1.0 was fueled by interest Corruption 2.0 is driven by ignorance. Suggesting for example that copyright laws just don’t work in the modern world he used their application to music, videos and other online content to support this assertion. And I must say that this resonated and I wholeheartedly share this view. The situation as it stands with copyright law and definitions of fair use is just not tenable moving forward. And to bring things back on track let us note that their application came about through ignorance. These are not instruments of the 21st century designed for the purposes to which they are being put. But rather instead antiquated and somewhat inflexible instruments which should be laid to rest rather than clumsily applied to digital media.

The interaction between technology and law, and the rapid pace of development of the former compared to the latter, is leading to outcomes that are unforeseen and in a great many cases far from ideal. For example the R/W culture should not be illegal. And whilst it is there will be much confusion, fear and a divide between those who feel empowered else worry not about repercussions, and those who are less informed, err on the side of caution else are simply a victim of the application of legislation that is not fit for purpose. And rather worrying is the fact that this divide may become most pronounced on an international level, between nations who choose to take significantly different approaches or with contrasting interpretations. There will be those who benefit from continued freedom and those who have been put at a disadvantage by ill-informed legislation.

Of course the bad news doesn’t end there and for fantastic examples in the UK of ignorance-driven legislation you only have to look to the proposed schemes for national ID cards and e-Voting. Where it is obvious to anyone who understands the technology that such things have the potential to lead to unspeakably bad outcomes. And I’m not just talking about the fear of a shift toward a police state, but the potential for our national security to be compromised and our democratic system put at risk.

That is not to say that all such legislation is driven purely by ignorance, and Prof. Lessig asked us to consider how it is the Patriot Act managed to come about so quickly after 9/11. Going on to suggest that it lay in waiting for such an event, and this is not hard to believe. On asking Richard Clarke if something similar might lay in waiting for an i9/11 Lessig was apparently informed that of course there is and “Vint Cerf won’t like it”. From which we can safely assume that this would mean the Internet losing it’s generativity/net-neutrality. Yes, it could be that the current Internet and the freedom it affords will some day soon be a thing of the past - a much reminisced Utopian vision of what was.

Thankfully we are not there yet and Lessig suggested how we might avert this and other digital disasters. This took the form of a call to the geeks to engage with those making legislation, and to inform them such that ignorance is not enacted in policy. Tackling some of these issues in the US there are organisations such as the Electronic Frontier Foundation and in the UK we have the Open Rights Group. But it is obvious that a greater and more diverse effort is required. For example consider that in the UK a huge slice of radio spectrum is going to be freed up with the move from analogue to digital terrestrial TV. And that with the generativity afforded by modern computing + the Internet this precious resource becomes even more relevant to our every day lives. With good legislation it could for example enable a high-speed almost zero operating cost network that has the interests of the individual at it’s core, and supports community, arts and commerce. Whereas bad legislation here has the potential to at best enable business models that line the pockets of shareholders, and a worst case scenario would be a waste of a most scarce resource that doesn’t bear thinking about.

The policy making means have been expanded due to technology and so the checks in place must also be expanded. And the time has come for the geeks to take a stand and to inform those in possession of a dangerous imbalance of power to legislate vs. technical facts.

Novell bites the penguin that fed it

So it would seem that Novell are further strengthening their links with Microsoft, and such moves in the long term may well be - and not undeservingly - the undoing of their Linux proposition. To address a few of the key points outlined in this latest strategy:

“an incremental investment in their relationship”

Read: a bad move that will serve to further distance Novell from the FOSS community, and one that will ultimately not serve them well. Thankfully Ubuntu is gaining some traction in terms of enterprise hardware support, and hopefully support from proprietary software vendors will follow. Frankly I think that the current situation with the certification old boy network - where for proprietary Enterprise software you mostly have the choice of Red Hat or Novell when it comes to supported Linux platforms - stinks, but I digress.

“converting unsupported Linux users to supported Suse Linux Enterprise”

Unsupported? It’s amusing the way enterprise software vendors harp on about the unsupported nature of FOSS. I think they’ll find many folks - and not just hackers/individuals - were using it fine long before the advent of wonders such as enterprise support for Linux et al, thankyouverymuch! Back in the days when they wrote off FOSS as merely kids playing, and instead splurged on many a proprietary software project which in cases hemorrhaged cash and never saw the light of day, else didn’t live up to it’s promises.

Of course the smart people still maintain a direct relationship with the community, such that they can reap the wider benefits from using FOSS and at a reduced cost. The less informed and more risk averse however require a vendor sandwiched in between, who will afford some level of security - the emperors new clothes? - whilst milking the relationship in both directions.

I would imagine that if any nation will take a less risk averse and more cost-conscious approach to software it will be China, and this will serve to fuel their already rapidly expanding economy. So I suspect the MS/Novell strategy will fall flat on its face there.

“builds a bridge between open source and proprietary software”

Or… Allowing you the peace of mind lock-in affords even when running FOSS. Value-add inverted!

“interoperability and intellectual property peace of mind”

A route to lock-in and support of Microsoft’s as yet and likely never to be disclosed or supported claims of patent infringement. The only way these dubious claims will ever gain traction is if people go round buying from Microsoft vouchers for Novell support / indemnity. And whether by accident or by design as a result in some way serve to validate Microsoft’s claims.

Back Standard Time



Similar to my fascination with radio I’ve long been interested in time. From the creation of references and it’s measurement, to our perception of time and the way this is effected by things such as environmental factors, current mental state and our age. And there are many interesting links between the two: from the most obvious of the simple relationship between frequency and time, to the propagation delay of radio signals and the somewhat romantic notion that if you travel far enough away from earth you could pick-up signals from say a 1920s radio broadcast.

One evening coming up for around two years ago I checked the time of day as it was purported to be by a number of time keeping devices around the flat. And much to my annoyance found that they all disagreed and by up to 20 minutes. With the worst perpetrator known to be my mobile phone - a Sony Ericsson M600i which can lose 20 minutes in a matter of a few months. Following this episode I vowed to build an accurate time reference, and something a bit more interesting than simply synchronising a computer to someone else’s NTP source, or purchasing an off the shelf radio controlled watch. After a little research I decided I’d follow a combination of a design of Brook Shera’s that uses GPS to discipline an oscillator and thus provide an extremely accurate clock signal, and a design of John Ackermann’s which would in turn use this to clock an embedded PC. The PC could then be used to drive a display and distribute time via NTP. And so I proceeded to start collecting the parts needed to construct a very accurate time reference, which would provide a local display and distribute time via the Internet to remote sites.

Now it would have been fine had the idea ended there. However I acquired a 1940s IBM master clock, once used in a factory to drive many slave wall clocks and possibly clocking-in machines. And decided that the pulse-per-second output from this should be used to discipline the oscillator which clocked the embedded PC. This I feel will be much more interesting than using the GPS constellation as the ultimate reference and will enable me to create my own time zone - Back Standard Time (BAST). And after all why should I subscribe to the UTC? I don’t believe it is compulsory yet. Of course in an effort to preserve the sanity of it’s users at the epoch of BAST it will be synchronised to the commonly accepted UTC. I haven’t decided as yet but I may choose to additionally re-synchronise at predefined intervals. So as to ensure that as UTC drifts from BAST I do not lose my friends and my job as a result of my perceived bad timekeeping. These sync events would provide the opportunity to adjust the master clock such that a BAST second is as close as possible an approximation of the SI base unit of time. Or alternatively to switch to say the Furlong/Firkin/Fortnight system of measurement’s base unit - the microfortnight - for periods that ought to be longer in duration, E.g. an important day. It is likely however that even with periodic synchronisation it would prove beneficial to be in possession of the current temporal error in UTC, and this could be obtained through comparison of GPS derived time with BAST. And details yet to be worked out include the practicalities of switching from one base unit to another, E.g. from SI to FFF units.

For the main system the signal path will be as follows: pendulum regulated pulse-per-second -> disciplined oscillator -> frequency multiplier - > embedded PC. The embedded PC will then generate SMPTE timecode which will in turn drive a primary and an auxiliary electronic display. Again there are still some details to be worked out, such as how the time signal will be distributed locally, as it is hoped this can be done without cables but whilst not introducing an unacceptable level of error. It is also planned that the time will be available at remote sites via NTP, and via a PSTN service which will play a series of pips at a regular interval. Rather than computer generated the pips will be recorded to tape and played back via a data mass storage device that once formed part of a Patriot missile system. And it would make sense for the current error in UTC to be published online, to enable those operating on BAST to calculate the more generally accepted local time as UTC would purport it to be.

If the project is successful the system will be extended and the pulse-per-second signal will also become reference for regenerated mains electricity, since mains frequency is prone to drift according to load on the grid. In this auxiliary system the mains supply is rectified to DC, and then AC regenerated at precisely - as disciplined by the IBM master clock - 50Hz. This clean regenerated mains would then be used to power any household appliances which employ a synchronous motor. First and foremost would be a record player, which relies on the accuracy of mains supply frequency to regulate it’s rotational speed. And whilst devices such as the modern washing machine will likely use control methods much more complex than a simple synchronous motor to regulate the rotational speed of the drum, they will likely have a digital controller that can be clocked via an external source. A synchronous home is a happy one.

So there is a lot of work to be done. Next I think I’ll obtain the rest of the parts for and then assemble the disciplined oscillator. Following which build the embedded PC and obtain a frequency multiplier to sit between the two. At this point I can test the this part of the system using a GPS receiver as pulse-per-second source. And then I’ll also need to renovate the IBM clock and make a plinth with adjustable feet for it to sit on so that it can be leveled out - it really must sit level. It would usually be hung from a solid and square wall, but since I’m not likely to own property any time soon I best not go drilling walls and fitting rawl bolts! The clock also needs it’s pendulum rod straightening and so I need to find somewhere capable of doing this with some accuracy.

In any case I thought a good start would be to write the idea up. And this combined with my now having bored (or perplexed) a number of people with tales of the plan should give added impetus. It’s one thing to have an idea and something quite different to take action and see it through to completion. And I do hope to see this through to completion as I believe it would prove to be a satisfying project. However if I don’t at least I have to some extent now documented the idea, the collected parts can all be used in less ambitious projects and hooking up the various subsystems will in itself be fun.

Vint Cerf at the Inaugural WCIT Talk

Livery Company of the City of London the Worshipful Company of Information Technologists held their inaugural talk at City University’s Cass Business School. And to see them off to an incredible start they managed to secure as a speaker none other than ‘father of the Internet’ Vint Cerf.

I won’t go into Vint’s history here as there is plenty written about him on the web already, and for a brief introduction you can follow the previous link to his Wikipedia entry. But I’ll cover in brief just a few of the challenges Vint asserted that the Internet faces moving forward:

  • The Internet was designed to not care about content. And it’s log term success relies on this continuing to be the case. Services providers must not tamper with it’s neutrality!
  • Internet access must be symmetrical. ADSL and similar services that are asymmetric - where you typically get much less upload compared capacity to download - will limit the applications we can build.
  • It’s time for IPv6. Only a few years before we run out of unique IPv4 addresses. Google tested access to their services over IPv6 last month and Vint is pushing for this to become production.
  • Video-on-demand models are wrong. Most content is pre-recorded so there is no need for it to be delivered in real time. Suggested this should be trickled out over time. Advertising could also be bundled with the video. And we need to investigate new revenue models, E.g. an unobtrusive Google-like approach where you can click on an item in-picture that links you off to the website of a retailer who stocks it.
  • No to bandwidth shaping! This is a bad idea and we just need to upgrade the Net where necessary. Do away with short-sighted business models that are based on over-committing backbone and/or upstream bandwidth capability. Give customers a guaranteed data rate and allow them to go over this when there is spare capacity in the network. This is the only way we will realise the full value from applications.
  • The Internet has brought about new business models and will bring about an end to old models. Adapt or die!

Note that the above has been shabily crafted from a set of scribbled notes and these are not Vint’s precise words. I had to keep reminding myself to take notes as he’s such an engaging speaker that I found it difficult to look down and write! He’s one of those rare folks who is very rightfully a living legend. And that posses a deep and wide understanding of the subject matter, are able to pepper it with historic detail and amusing anecdotes, and perhaps most importantly have a lucid vision of the future.

European Legal & Licensing Workshop

Last Friday saw the inaugural European Legal and Licensing Workshop take place in Amsterdam. Hosted by the Free Software Foundation Europe this was the first of what is hoped will be a series of events to facilitate discussion and networking amongst members of the European FLOSS community. With the goal of supporting the effective and appropriate adoption of free and open source software at commercial organisations spread throughout the union. And let us not underestimate the opportunity here: workshop chair Shane Coughlan brought to our attention recent research1, which suggests that free software is expected to account for up to a third of the European ICT industry and to contribute up to 4% of the EU GDP by 2010! Whilst an impressive predicted growth, in order to minimise growing pains it is clear that we must better understand the issues enterprises face when looking to adopt FLOSS technology. And licensing is one area that would definitely benefit from clarification, guidance and best practice that informs the associated necessary business processes.

The workshop was well attended by both lawyers and technical folks, representing a range of interests including open source projects, IT organisations, consumer electronics companies and law firms. With key community figures present, lawyers specialising in FLOSS and experts from a number of major global IT and consumer electronics vendors.

Over the next few months the FSF Europe plans to continue work on developing documentation that will assist organisations looking to adopt FLOSS technology. To organise further Specialist Interest Group meetings, and to continue to facilitate cooperation between it’s network members in support of the delivery of knowledge to 3rd parties. And I hope I can find a way to contribute to these highly commendable initiatives!

UKUUG OpenMoko Talk

The UK Unix User Group hosted a talk Wednesday on OpenMoko and secured as a speaker one of the project’s wikimasters. The main focus of the talk was what applications might it possible to build using a smart-phone based on the platform. It was not terribly technical and mostly conjecture as to what might be possible given a small computer running Linux, with integrated GSM, GPS and WiFi. Whilst I was fine with the talk not being very technical I did get a little bit bored with the obsessing over application possibilities. Sure, there is great potential. But let’s not get carried away and forget that smart-phones with such hardware capabilities have been around for some time, vendors such as Nokia and Sony-Ericsson Etc. are not dumb and they will have thought long and hard about potential killer applications. And to be honest I don’t see much evidence of them, do you?

There are other things that I think the speaker should have covered. Such as how an open smart-phone platform could bring benefits to the world of mobile telephony and PDAs similar to which Linux brings to the desktop. So to start with a rich ecosystem that provides countless applications and a knowledgeable community that is keen to share the love. Or how about interoperability and the elimination of whacky mobile platforms that have more in common with early 80s home micros. Want to run that Symbian application you bought on your new Windows Mobile device, or even share data between similar apps on each platform? Welcome back to 1983, a time when your Sinclair Spectrum didn’t want to play with your BBC Micro… Or how about the opportunity to standardise mobile phone UIs. Or perhaps how OpenMoko might enable smaller businesses to enter the smart-phone market without having the might of someone like LG or Motorola.

That said the speaker had boundless enthusiasm and an ability to articulate clearly to a non-technical crowd. Qualities that are highly valuable to an open source project.

Also of note and pictured above was the presence of a prototype GTA02 ‘FreeRunner’. Likely the last revision prototype and one of <5 in the UK this was the property of OpenMoko developer Thomas Wood. A contributor funded by his employer OpenedHand Thomas appeared to be very clued-up, was the subject of much envy and created his own audience at the back of the room.

I must say the FreeRunner is shaping-up quite nicely, and with some work on the software’s power management, UI and reliability of call capability so will OpenMoko. OK so that made the software platform sound pretty bad and this really isn’t the case. Or rather an awful lot has been achieved and I don’t think it will be that long before most of these points are addressed. And in fact I suspect that these are being worked on right now. Once the production hardware is out and a basic functional and reliable software release, I’m certain the pace of development will benefit from exponential growth as many geeks readily part with their cash and join the party. And I would not be at all surprised if just like the hotly anticipated and then much in demand EeePC, initial demand outstrips supply.

A Sequence of Records

I recently put together a ‘mix-tape’ for a friend and it was the first I’d done in just coming up for 5 years, an enjoyable process and I’m not sure why I left it so long. I guess part of the reason is that these days I don’t get paid to play records and as a result spend much less on acquiring vinyl. And so it feels like I just don’t have sufficient influx of new music to warrant attempting to loosely stitch together a sequence of tracks that I’ll find pleasing, and if I’m lucky others may. In any case to mark the moment I thought I’d share it with a - in theory - wider audience (assuming anyone reads these ramblings). It’s a collection of old and new, and fairly weighted toward post-punk and Glasgow.

Liberating the Electromagnetic Commons

Aurora I’ve always been fascinated with radio and it’s many applications: from Rugby’s MSF time signal and long-wave broadcast radio, through HF amateur radio and VHF PMR, to television, wireless networks and satellite navigation systems. Yes, I’m a radio geek.

So it should be of no surprise that I take a keen interest in how our incredibly scarce resource - the electromagnetic spectrum - is managed. And let’s be clear it is our resource as it truly belongs to the people and is not the product of the labours of an organisation or state, despite what some would rather have us believe. But since it is a finite resource and one of such value there is no avoiding the fact that it must be carefully managed. And this comes down at a top level to government agencies such as the FCC in the USA and Ofcom in the UK. Up until now such agencies have largely done a good job of managing this resource and ensuring that spectrum is shared fairly and amongst a diverse range of users with varying needs. Of course for this thankless task they have not gone short of a bob or two, as has been demonstrated most visibly via the auctions for spectrum required for operating a 3G mobile service in the UK, which raised in excess of £22billion.

At the end of 2006 Ofcom consulted on the proposed approach to the award of the digital dividend spectrum, I.e. that which would be freed-up at the cessation of terrestrial analogue TV (470 - 862MHz). Now, this really is prime spectrum. Not only is it a monstrously fat slab of the stuff just short of 400MHz wide, it is also slap bang in the middle of top dollar electromagnetic real estate. These are not feeble microwaves that are severely attenuated by walls, nor are these HF or VHF signals that require awkwardly large aerial systems. This is about spectrum that can not only provide decent radio bearers for communications of respectable bandwidth but that are robust and can travel a fair distance.

Sadly Ofcom’s DDR was far from accessible. And I’d go as far as saying that the documentation they provided in support of people making informed decisions was impenetrable, and I very much doubt that anyone fully digested it unless they were being paid (lots) to do so. I attempted to wade my way though the hundreds of pages of analyst hell and let’s just say that it succeeded it breaking my spirit a little, as perhaps can be seen in my eventual response.

What should be done with the freed-up spectrum? Electron Club associate Michelle Kasprzak blogged about the review quoting my view at the time as made in comments to the EC mailing list. Since then my opinion hasn’t changed much, and if anything I’d just put a stronger emphasis on community networks. The ISM band as allocated for unlicensed use with 802.11 has already in some built-up areas become virtually useless. And we have no capability for long distance links unless you’re prepared to break the law and use high gain antennae and/or RF power amplifiers, and at the detriment of other users as you compound interference problems. And so there is just no getting away from it: we need more spectrum, better spectrum, and quite possibly new ways of managing it. For use by the people and with their interests in mind. I’m not interested in 3G and I really don’t care much for WiMAX, and the shifting sands that are the business models that underpin these technologies. What I want to see is the decentralisation of network provision. I want the principles embodied in Web 2.0 mapped on to the electromagnetic spectrum and the physicality of network access. This is where the next big revolution will occur, and it may well be televised but if so it will be transported across TCP/IP and thanks to a free radio bearer.

I’m pretty confident that the time is right for this revolution and as a possible indicator we have the advent of IEEE802.11y in the USA. And it is quite likely that recent and potentially disruptive technologies such as software-defined radio and cognitive radio will be key enablers. So it is not simply a case of demand but one of definite possibilities. The question now however is what might these new operating models might look like and how can we foster a community empowered to effect such change.
