Custom PC, Issue 220

Custom PC Issue 220This month’s Hobby Tech dedicates a whopping four pages to one of the most interesting devices I’ve ever had on test: the MNT Research Reform open-hardware laptop. If that weren’t enough, there’s also a look at a classic book of early personal computing history: Ted Nelson’s Computer Lib/Dream Machines.

The meat of my latest five-page column is a relatively straightforward review of the MNT Reform, a laptop that’s anything but straightforward. The brainchild of MNT Research, and the second-generation of the core design, the MNT Reform is open – from the design of the chassis with its eye-catching transparent base to the electrical designs for the motherboard, system-on-module, and even the 3D-printed trackball which sits below a mechanical keyboard.

As a laptop, though, it’s easy to find the Reform wanting on a number of fronts – from lacklustre performance to the absence of niceties like having it suspend when you close the lid. I then dive deeper into the project itself – and reveal something both unique and absolutely worthy of celebration, with an enthusiastic and growing community boding well for its future.

Two of the biggest issues highlighted in the review have since been resolved for future production runs: the trackball has been greatly enhanced by the addition of steel bearings, and the troubling power drain while “off” which can empty the batteries has been addressed with a firmware update to put the system management controller into a low-power deep-sleep mode.

Computer Lib/Dream Machines is, despite having been published in 1974, a publication with a very similar ethos at its heart: the idea that computing not only should be accessible to all but must be accessible to all. Long out of print, despite Microsoft’s efforts to publish a professionally typeset and updated version of the eclectic original in 1987, the book manages to be both of-its-era and yet somehow entirely relevant – and that’s even before you flip Computer Lib over to reveal Dream Machines as a second book bound as one.

The original version of the book has been preserved at The Internet Archive, and is well worth a read – though its format means you may spend quite some time zooming in and out.

All this, and more, is available now at your nearest supermarket or newsagent, online with global delivery, or as a DRM-free PDF download from the official website.

PC Pro, Issue 222

PC Pro, Issue 222Continuing my features work for Dennis Publishing’s PC Pro magazine, the April 2013 issue sees the publication of The World’s Fastest Computers. A research-heavy look at supercomputers and the high-performance computing (HPC) industry in general, it’s a piece of which I’m particularly proud.

Before getting into the nitty-gritty of the piece, however, I’d like that thank a few people without whom the feature could never have happened: Professor Simon Cox, of the University of Southampton, was a particularly excellent source, speaking to me candidly and at length regarding the realities of running a supercomputing facility and his hopes for the future, and even posing for some photographs to liven up the piece; Nvidia’s Ian Buck, GPU computing general manager and creator of the Compute Unified Device Architecture (CUDA) language, brought years of highly-parallel thinking to the mix, as did Nvidia’s Tesla boss Sumit Gupta; Intel’s Stephan Gillich, director of high-performance computing for the EMEA region, provided a CPU- rather than GPU-led perspective; and finally the Science and Technology Facilities Council was kind enough to provide copyright clearance on several of its historical supercomputing images – including a great shot of a denuded Cray being dismantled at the end of its service, which sadly had to be cut from the piece for space reasons.

The piece is split into three clear sections: a brief history of supercomputing, from the days of the Control Data Corporation 6600 – Seymour Cray’s first HPC design, and the very first system to be described as a supercomputer – to the modern day, followed by a look at what HPC means for education and the industry. The final part, meanwhile, is a look at the future – which, you’ll be amazed to hear, looks very different depending on whether you’re talking to Intel or Nvidia.

Perhaps the most interesting aspect of the piece, for me, is the performance comparison: using data provided by Professor Simon Cox and a great deal of research, I was able to piece together a rough approximation of a performance timeline. Starting with the Ferranti Pegasus in 1956 and working through thirteen other machines – all of which have, at one time or another, been installed at the University of Southampton – I compiled operations-per-second statistics for each. This, more than anything else, demonstrates the runaway nature of high-performance computing: using a linear graph, all but the last two machines – both versions of the University’s current Iridis supercomputer – drew a flat line.

While there’s plenty of information that didn’t make it into the final piece – I compiled nearly 30,000 words of interview material in all – it’s by far one of the most comprehensive I’ve written, and one of which I think I can be justifiably proud.

If any of that tickles your fancy, PC Pro Issue 222 is available in newsagents, supermarkets and doctors’ waiting rooms throughout the country, or digitally via Zinio or Apple Newsstand.
