The previous state of the driveway is shown below.
We were all hard at work after the lorry departed, shovelling and wheelbarrowing and raking. I had to take a break halfway through - without the rowing machine I would probably have died!

Driveway (Sept 11th update)
On Tuesday, September 11th I discussed the poor state of the driveway, and Mark's proposal that we should collectively invest in 10 tons of chippings to resurface. The lorry arrived on Saturday and here is the result.

Grammar
Previous post: The new Roman Empire?
"Fox points out that a number of 'first citizen's (as Emperors called themselves for the fig-leaf of legality) were assassinated in the name of freedom - Julius Caesar, Caligula and many subsequent."
____________
"It should be subsequently"
"You mean I put an adjective where it should be an adverb? "
"It's a mistake."
"Actually there are two parses of that sentence. There's the one you mention. But in my parse there's a subsequent elided word, namely Emperors. That's why it's OK to use an adjective."
"You're arrogant too."

The new Roman Empire?
It's commonplace to identify America today with the Roman Empire.
I've just finished Robin Lane Fox's wonderful "The Classical World: An Epic History from Homer to Hadrian". Fox points out that a number of 'first citizen's (as Emperors called themselves for the fig-leaf of legality) were assassinated in the name of freedom - Julius Caesar, Caligula and many subsequent. In each case it proved politically impossible to restore the Republic. Augustus proved the point by dallying away from Rome until the senators called him back in desperation to sort out disputes.
Fox is less analytic as to why this might have been the case, but it was surely a function of the lack of senatorial legitimacy amongst the plebs, and perhaps more importantly, the legions, each of which needed a champion to secure their wages, and colonisation land once they had finished military service.
In a patronal society (one we would today call deeply corrupt) a hierarchy centred around one individual seemed to be optimal in managing power and resource relationships.
Which major power does this sound most like today? Russia.

TrueCrypt (+ rowing machine)
I had a backup problem: six Gigabytes of technical, client and financial data which needed secure storage. I have a very big flash drive, which I can store off-site, but the data needs to be encrypted.
I thought Vista might come with an encryption program. Microsoft Office 2007 has effective (AES) file-level encryption these days, but Vista has nothing which works on folders, Gigabyte or otherwise.
A quick web search led me to TrueCrypt. This is a great freeware product which allows you to set up encrypted 'volumes' - stored as files - on your hard drive (it does other stuff too). The 'volume' looks like another disk or flash drive when you use it and is very securely encrypted. Once past the password, data can be accessed and copied as from any other data store. The advantage is that the data is encrypted on the hard disk itself - great if the laptop were to go missing - and the volumes can be copied straight across to USB drives. This I have now done.
I made a donation and after finishing this, I'll go read the manual.

The engineer called lunchtime to fix the Oxford II rowing machine. The trip-computer/console had been behaving erratically and basically not functioning for a while. Replacing the unit had not fixed the problem. The engineer determined that a cable had been crimped when the horizontal aluminium rail (on which the seat slides) had been moved to its vertical 'park' position. I reckon it's a design flaw. Anyway, it works now so no excuses.

Minkowski diagrams
In special relativity we hear a lot about length contraction - objects such as spacecraft and the ubiquitous 'rigid rod' 'get shorter' as they approach light speed. People don't get this. Does the rod 'really' get shorter or not? It seems to depend on the observer, defying Aristotelian logic and common sense.
An excellent Wikipedia article on Minkowski diagrams clears the whole thing up. The problem is with our use of language. When we say 'spacecraft' or 'rod' we are making a spacial statement - the object considered at a 'now'. But that immediately invalidates special relativity.
Instead, we have to consider the space-time object extended in space and swept out over a defined time. This extended space-time object at a particular 'now' is viewed differently by differently-moving observers because their 'now's are differently-oriented. Specifically when you view an object travelling fast past you, the spatial slice you measure as being the length 'now' is rotated as compared with the 'now' length measured by an observer travelling with the rod. And the rotated view is shorter. It's made clear in the diagram below, with explanatory text pasted in from the article.
Notice, by the way, that this has nothing to do with the time taken for light to get to you from different parts of the object at your 'now'. Your length measurement has to correct for those effects, and after the correction you compute that the 'length' is shorter.

"Relativistic length contraction means that the length of an object moving relative to an observer is decreased and finally also the space itself is contracted in this system. The observer is assumed again to move along the ct-axis. The world lines of the endpoints of an object moving relative to him are assumed to move along the ct'-axis and the parallel line passing A and B respectively. For this observer the endpoints of the object at t=0 are O and A. For a second observer moving together with the object, so that for him the object is at rest, it has the length OB at t'=0. Due to OA being less than OB the object is contracted for the first observer."
* Excerpted from the Wikipedia article.
The point is made more clearly by the following thought experiment in the diagram above. Suppose, according to the 'blue' observer speeding by, that the rod flicked into existence 'all at once' for a millisecond along OB, then vanished again. The 'black' stationary observer would not see a rod at all, but would calculate a thin slice of material which sprang into existence close by and seemed to move away much faster than light (although it would visually appear to be slower than light due to light propagation delay from more distant parts of the rod). The 'spatial' rod would, in fact, have been rotated a little into time from the stationary observer's viewpoint.

New Laptop -- update
I knew it was too good to be true ... here's the note I've just emailed off to technical support.
Hi,
I today bought an Advent notebook computer at PC World Basingstoke running Vista Home Premium Edition.After installing a few programs (Office 2007, Frontpage, etc), I am now getting a window saying:
Microsoft Visual C++ Runtime Library
_______________________________
Runtime Error!
Program: C:\Windows\explorer.exe
abnormal program termination
[OK]
Shutting down and restarting hasn't removed the problem. If this error window is closed, or the OK box clicked, the window vanishes, the desktop icons vanish and Vista seems to go back to the final part of its power-up sequence. Then the wretched error window comes back again.
Any ideas?
Thanks,
Nigel.
PS: It turns out that this is a frequent symptom of an incompatability of Vista with an old program. In my case, my old encryption program. I've uninstalled it, and the problem has gone away.
The tech guy on the phone was confident he could solve this problem, and took great pains to steer me to the one minute automated quality assurance feedback after he'd finished. I, of course, gave him 5 out of 5 for helpfulness, accuracy, courtesy etc.
So that's how they manipulate their scores!

New Laptop - Oct. 16th 2007
With several possible work leads in sight, I decided I had to have a new laptop. My BT laptop, which I've been using for work the last 16 months, went back to BT a couple of weeks ago. My 'other' laptop, a Toshiba which I bought back in 2003, is showing worrying signs of ageing. The sound card occasionally gives up entirely, and the erratic functioning of the PSU has led to heartrending bleeping noises from the almost-drained battery on too many recent occasions.
So off to Basingstoke PC World this morning with Adrian, where we were helped by a charming young Polish tech guy with an unnerving grasp of the equipment choices on sale and their respective pros and cons.
So -- I'm typing this on an Advent laptop with 1.8 GHz dual core processors, 2 GB memory, 120 GB HD, 802.11g WiFi and of course Vista. To be honest, Vista was a calculated risk, but so far it's proven remarkably intuitive and has also successfully loaded several of my XP programs without complaint. I have a few more to install, it being an all-day job to get a new computer into usable shape ...

Oryx and Crake
I did get to finish this (previous post) and it's a good book. Most of the excitement is generated in the episodic back story, while the main narrative crawls along in mundane, survivalist mode leading to a final existential crisis, left unresolved at the close.
Take a look at the Saturday August 18th 2007 post (not so long ago) on the Army of Dude blog here. Aren't you glad you're not Alex Horton, recently returned from infantry duty in Iraq? This blog has been referenced in the LA Times and in the current edition of The Economist. Tells it like it is, I reckon.
Today: personal paperwork updates (Will etc) + piano practice + music theory (cadences, phrases, scales) + getting a replacement computing console for the rowing machine (erratic display). Not enough hours.

Buried by Books
Last week was pretty busy.
On Wednesday I was in Swindon meeting the MD of a solutions consultancy to discuss a possible assignment. Thursday I was in London returning my equipment to BT following the completion of my Wireless Cities contract. Friday I was updating the Interweave Consulting accounts.
I also drafted a Q-and-A on my Wireless Cities experience. This is currently with BT so they can feel comfortable I haven’t breached any commercial confidentiality. When it comes back, it will be an asset in my Newsletter - part of my ongoing marketing campaign.
Meanwhile I am inundated with books!
1. My music theory class Thursday evening brought me “The AB Guide to Music Theory” which covers grades 1-5. I’m working through this as a priority.
2. On Saturday I had my piano lesson, where Suzanne has me focused on Grade 2 scales and the “Menuet in G Major” (BWV 114) from Anna Magdalena’s Notebook (made famous by The Toys' 1965 hit single "A Lover's Concerto").
Suzanne is into the mathematics behind the musical scales, and has lent me “Music - A Mathematical Offering” by Dave Benson. The mathematics which Professor Benson (Aberdeen University) has in mind includes Fourier analysis, Laplace transforms and group theory. Suzanne has expressed an opinion she might appreciate some help. I’m currently at chapter 2 (Fourier Theory).
3. Clare and myself both read the ancient Greece part of Robin Lane Fox’s “The Classical World” and ran out of time as we reached Julius Caesar. But it’s too good - we must continue!
4. I bought “The Indian Clerk” by David Leavitt after a rave review in the New York Times. This is a novelisation of the relationship between G. H. Hardy, feted Cambridge mathematician, and Srinivasa Ramanujan, unknown Indian clerk and mathematical genius. The basic story is quite well-known, but the novel delves deeper into the mysterious Cambridge Apostles, and other strange goings-on in the Cambridge high society of the first world war.
5. On the strength of several recommendations (and after reading “Atonement” and “On Chesil Beach”) I bought Ian McEwan’s “Enduring Love”.
6. Enthused by our recent archaeological trip to Greece, I bought “The Iliad” (Homer by way of a great translation from Stanley Lombardo).
“Rage: Sing, Goddess, Achilles’ rage, black and murderous, that cost the Greeks incalculable pain, pitched countless souls of heroes into Hades dark, and left their bodies to rot as feasts for dogs and birds, as Zeus’ will was done.”
Good first line, right?
7. I have Peter Hamilton’s recent SF blockbuster lying untouched on my shelves for several months now (“The Dreaming Void”).
8. Also a biography of Cantor I’ve had for years and would like to read properly.
9. Clare also has Margaret Atwood’s “Oryx and Crake” out on loan from the library, and I’m halfway through that.
Atwood is literary, so when she writes ‘science-fiction’ it’s ‘speculative fiction’. Put-downs aside, there does seem to be a real difference. The literary approach is to focus on people, personalities, character, motivation. These are real people in believable settings, and plot emerges from the interpersonal dynamics and is not the primary driver (although it’s there of course). Still it can be done well or badly and I’m not yet sure about “O & C”.
Most SF by contrast is plot/concept-centric with characterisation either perfunctory, or subordinated to whatever is necessary to keep the plot or grand ideas moving along. Easier to tap into the primary emotions of the reader that way (at the expense of enlightenment?).
It also pays better, as literary writers never fail to remind us.

My old reading glasses had made the transition to ‘computer’ glasses and a few days ago made the further transition to ‘out-of-the-way-drawer’ glasses. It’s really shocking the rate at which the eyes deteriorate as you get older.

Symmetry and the Monster (book review)
A review of "Symmetry and the Monster" posted on Amazon.com
According to the blurb on the back, the American Mathematical Monthly described this book as "truly a page-turner". I have to say it is not.
Mark Ronan's task is to take us through the history of group theory culminating in the recently-completed project to classify the finite simple groups. This has taken decades of work by large numbers of highly-skilled mathematicians, with proofs so long and abstruse that there is a genuine concern that no future generation of mathematicians will be able to comprehend them.
How do you communicate this to a lay audience? The key decision for the writer is to gauge his audience. Ronan's view is a readership which knows no group theory. He therefore can't even define a simple group: "a simple group is a group which is not the trivial group and whose only normal subgroups are the trivial group and the group itself" - Wikipedia.
The reader, lacking help in engaging with the subject matter, is instead entertained by concise and amusing mini-biographies and anecdotes about the many participants in the quest. Ronan is a little dry as a writer, but in general this works well enough, although he is too indulgent of such monstrous personages as Sophus Lie. The final milestone in the classification project was confirmation of discovery of the mathematical Monster, the largest of the 26 sporadic groups. This was big news even on conventional news outlets, such as the BBC.
In conclusion, this book will work for mathematicians who know some group theory and who like the historical context spelled out. I don't think many people not educated in mathematics will make it through to the end. With this in mind, Ronan could have profitably added a chapter at the beginning (or even an appendix) where he took the reader through normal subgroups, quotient groups and on to simple groups. He would then have been able to use correct terminology (his own merely irritates) and the journey would have been a lot more satisfying. Perhaps for the second edition?

Review of my book
The Publisher sent me the review below from Book News Inc. (June 2007) yesterday evening.
Business strategies for the next-generation network
Seel, Nigel. (Informa telecoms & media; 4)
Auerbach Publications, ©2007 298 p. $79.95
"Think way back, all the way back to the 1980s, to the birthing of the "Next Generation Network" (NGN) concept, when designers were building the future from what they could scrape from the past. The result was NGN all right, but also decidedly assembled from dead body parts. Consultant and experienced practitioner Seel reviews the failure of previous attempts to start fresh with such concepts as broadband ISDN, covering the net, TV and IT systems.
He also describes efforts by carriers to build newness in and transform themselves into enterprises without legacy systems, which leads to the business and technology issues of maintaining the idea of NGN, if not the reality. He then focuses on business strategies for both old and new players as they attempt to win over the consumer market. The result is both absorbing and alarming, if we still believe in NGN."

Glowing
Clare picked up a bug - she thinks it was on the flight home from Athens. Jetliners are notorious for not keeping the cabin air-filters clean, so that they become a repository for the bacterial load of passenger coughs and sneezes.
She claims the fever broke at 6 a.m. this morning. To tell you the truth, I was asleep at the time and couldn’t possibly comment. As we know, horses sweat, men perspire and women glow - I rather gather that someone was glowing like a pig here this morning.
Just in passing, what a delight to read the diary (here) of John Baez, who works in mathematical physics and category theory. His latest posting includes:
A few other random thoughts. Pretty impressive to see the Buddhist monks in action in Burma. I occasionally discover that various leading academics turn out to be Buddhists, which always seems to strike their colleagues as faintly exotic. There’s much which is admirable about the Buddha’s teaching, so it’s a shame there is so much baggage as well: reincarnation; the six realms with their hungry ghosts, the Asuras (jealous gods) etc.
I have previously waved the flag for Taoism - philosophical Taoism that is - cf. the Tao Te Ching - not the magical, god-riven debasements. The Chinese communists used to denounce Taoism as fatalism. I suppose it is fatalism to try to learn how to play a musical instrument rather than smash it, or to work with a group of people to creatively find a consensual solution rather than simply order them to do what you want on pain of violence. I guess effective Taoism requires its practitioners to be alert, intelligent, empathic, creative and persuasive: but you are allowed to use lethal force when all of the above falls completely on deaf ears.
The problem of Taoism is that it lacks the symbols, dogmatic doctrine, organisational hierarchy and processes which lesser philosophies rely upon to organise their adherents. I don’t know if the concept of a “Taoist monk” (in the correctly understood sense of Taoism) is even possible. An educated Taoist community certainly.
And just a final thought. So much political theory is based around the model of the idealised rational citizen. This may have worked great post-enlightenment, but in the era of evolutionary psychology, with the relevant traits (intelligence, personality-factors) normally-distributed across the population, treating “citizens” as political and moral clones is a very poor approach. Is anyone out there thinking of better models which don’t fall straight into the trap of elitism, eugenics and all the rest?
Anyway, back to work mode. All this is very interesting, but it’s a well-recognised diversion from getting down to write my white paper on lessons learned from the recent WiFi deployment I was involved with!

There’s much which is admirable about the Buddha’s teaching, so it’s a shame there is so much baggage as well: reincarnation; the six realms with their hungry ghosts, the Asuras (jealous gods) etc.
I have previously waved the flag for Taoism - philosophical Taoism that is - cf. the Tao Te Ching - not the magical, god-riven debasements. The Chinese communists used to denounce Taoism as fatalism. I suppose it is fatalism to try to learn how to play a musical instrument rather than smash it, or to work with a group of people to creatively find a consensual solution rather than simply order them to do what you want on pain of violence. I guess effective Taoism requires its practitioners to be alert, intelligent, empathic, creative and persuasive: but you are allowed to use lethal force when all of the above falls completely on deaf ears.
The problem of Taoism is that it lacks the symbols, dogmatic doctrine, organisational hierarchy and processes which lesser philosophies rely upon to organise their adherents. I don’t know if the concept of a “Taoist monk” (in the correctly understood sense of Taoism) is even possible. An educated Taoist community certainly.
And just a final thought. So much political theory is based around the model of the idealised rational citizen. This may have worked great post-enlightenment, but in the era of evolutionary psychology, with the relevant traits (intelligence, personality-factors) normally-distributed across the population, treating “citizens” as political and moral clones is a very poor approach. Is anyone out there thinking of better models which don’t fall straight into the trap of elitism, eugenics and all the rest?
Anyway, back to work mode. All this is very interesting, but it’s a well-recognised diversion from getting down to write my white paper on lessons learned from the recent WiFi deployment I was involved with!
