South Queensferry

I’ve just finished a most enjoyable day of meetings here at the Amazon development centre in South Queensferry, just outside Edinburgh. It’s been very windy and (mostly) wet here, so I wasn’t able to get out at lunch to take any photographs. Also, the window of opportunity is small: at this latitude, this close to the solstice, there isn’t much daylight: sunrise is at 8:34am and sunset at 3:39pm.

Time to head back to the hotel (just the other side of a very busy roundabout, with lots of bridge traffic). I do have an umbrella, but from the howling wind I don’t think I ought to use it.

Blogging on the train

Did you miss me?

At this moment I’m sitting in seat 21A, coach L of the 11:45am train from King’s Cross to Edinburgh. It’s 2:57pm, and we’re just pulling out of Durham, so there’s still nearly two hours to go. Fortunately the train has free WiFi and there’s a decent meal service: I have a nice bottle of Lebanese red wine to go with the various snacks that keep appearing.

The flight from Seattle to Heathrow was delightfully uneventful; the Economy Plus section of the B777 on the ORD-LHR leg was almost empty. (Good for me, bad for United.) In a first for me I was carrying on all my bags, so I sailed through customs at Heathrow, caught the bus to Oxford, and made it there before sun-up.

I had a most enjoyable Thursday and Friday with my mother and brother in Oxford. (Friday was Lorna’s 91st birthday.) On Saturday, Alec Muffett came up and he and I spent a delightful time in Oxford. Covered Market, lunch at the King’s Arms, self-indulgence at Blackwell’s, dessert at the wonderful patisserie Maison Blanc, some shopping, and then back to Lorna’s.

This morning I set out to Edinburgh. I was booked on the 9:38 train from Oxford to Paddington, and some deep-seated skepticism made me catch an earlier bus and get to the station just after 9. At 9:15 they announced that the 9:38 train was cancelled. Almost immediately, they informed us that the train at Platform 3 was the 9:05(!) to London. There was a moment of chaos as all of the passengers who were booked on the 9:38 (including yours truly) dashed towards the 9:05….. Fortunately I arrived at Paddington in plenty of time to catch a Circle Line train to King’s Cross and I boarded the 11:45 train to Edinburgh at 11:30.
GNER train

We’ve just arrived at Newcastle station. I haven’t been here since 1976. Back in the 1970s I was a post-grad student at the University of Newcastle-on-Tyne, and between 1973 and 1976 I would regularly travel between Newcastle and London. Since then I’ve never returned; even today, I’m only passing through. How strange.

pecunium on torture

Must-read: Terry, on Torture, and what it is. Remember: Terry knows what he’s talking about. He understands interrogation in the way that no politician or pundit can. He’s a professional.

Padilla’s treatment is an outrage. Not just that it happened (secret prisons aren’t really that hard to make, nor even to keep secret) but that when the details come out, no one seems to care.

Freeman Dyson

I just got back from the Freeman Dyson talk at the Town Hall. I’ve always liked his writing – I thought Infinite In All Directions was wonderful – but I’ve been concerned with his wobbly thinking after the Templeton Prize. See Edge #180 for Dawkins’ scathing comments about Dyson’s Templeton piece. Like Dawkins, I don’t know what to make of stuff like:

I do not make any clear distinction between mind and God. God is what mind becomes when it has passed beyond the scale of our comprehension. God may be either a world-soul or a collection of world-souls. So I am thinking that atoms and humans and God may have minds that differ in degree but not in kind.

Since I’m one of those people who think that “minds are what brains do”, this is completely incoherent.
Anyway, the talk began with a very entertaining introduction by George Dyson, Freeman’s son, which included the clip from ST:NG where Picard speculates that an object that the Enterprise has discovered might be “a Dyson sphere”! As Freeman Dyson later commented, everybody completely misunderstood him: he always meant “biosphere”, specifically a loose assemblage of inhabited objects orbiting at the right distance from a star. A rigid sphere would be mechanically impossible.
Freeman Dyson’s talk was actually on biotechnology. It’s taken people less than 50 years to go from the first computers to a total addition to pervasive computer technology. He expects the same thing to happen to biotech over the next 50 years – complete domestication. He got a bit mystical over evolution – in the beginning everything shared genetic information horizontally – “open source biology”; then some organisms got selfish and Darwinian evolution kicked in; now humans are ushering in a new era of genetic sharing, marking the end of the “Darwinian interlude”. A rather blinkered view, IMHO. There was stuff about creating plants with silicon leaves to boost energy capture from 1% to 10%, and an impassioned plea for scientific freedom from political interference. And er… that’s it.
The questions were mostly softballs about energy futures, and the wonder of mathematics, and so forth. And then someone asked him about science and religion, and Dyson got all hot and bothered and ranted about Dawkins for a bit, and then realized that he was getting over the top, and backed off. And then I left. I hope many of the audience (200+) bought his new book; since I’ve already read most of the essays (reviews from the NYT, NYRB, etc.), I didn’t bother.
PS It was odd to be back at the Town Hall for the third night in a row – two Tallis Scholars concerts, now this lecture.

Site update

Hard on the heels of the DDoS attack on Saturday, this site was inaccessible for much of Sunday. (In fact I still can’t get to it from my Mac back in my apartment.) Put it all down to planned work, bad luck on Steve’s part, and bad planning on mine.

For a variety of reasons, Steve decided to move grommit to a new co-location center. The move was scheduled for Sunday afternoon (PST), and we all had plenty of time to prepare for it. As Steve describes in his blog, the move itself went OK, but he was caught out by a couple of bad Solaris patches that he decided to install. However by about 9 o’clock everything was up and running.

Everything except geoffarnold.com.

I’d forgotten that our DNS address would be changing, and at 9 o’clock I was enjoying the Tallis Scholars‘ concert at the Town Hall when I received an email from Steve reminding me to update my DNS configuration. After the concert, I headed home, worrying as I went about whether I could remember my login for everydns.net (and hoping that my on-file email address wasn’t the geoffarnold.com one – or, even worse, my old Sun address!). Fortunately I was able to log in and make the changes without any difficulties.

So how come I still can’t access geoffarnold.com from home? Put it down to lack of foresight on my part. The DNS “A” (address) record for geoffarnold.com, the bit that tells other computers what my IP address is, has a TTL (time to live) of 86400. That’s 24 hours, expressed as seconds. So any DNS server that retrieved my address less than 24 hours before I made the change is perfectly entitled to use that copy until the TTL expires. This means that everybody should get the new address in about 14 hours from now. If I’d been thinking ahead, I would have logged in to everydns a couple of days ago and adjusted the TTL down to, say 3600 (one hour). That way, when I actually changed the address, I could be sure that the stale information would be gone within an hour.

Next time, next time.

If you've been having difficulty reaching this site….

This is why:

OpenDNS, the San Francisco security startup that runs the PhishTank anti-phishing initiative, has been hit by a massive DDoS (distributed denial-of-service attack).
The 400mbps botnet attack did not affect the company’s core recursive DNS resolution service. The OpenDNS.com home page and corporate blog were crippled for about 90 minutes on Dec. 1.
The attack appears to be targeting EveryDNS, a sibling business owned and operated by OpenDNS CEO David Ulevitch. OpenDNS uses services from EveryDNS.

I actually got hit from two directions. First, I use EveryDNS as the DNS authority for geoffarnold.com. Second, it turns out that one of EveryDNS’s servers was located in the same physical rack as grommit (the system that hosts geoffarnold.com), so the attack consumed most of the bandwidth into our (shared) switch.

This is unusual

I arrived at the Town Hall at 6:30 for the pre-concert talk before the Tallis Scholars recital…. only to find out that the consort is delayed en route. It’s now 8:30, the organizers have arranged an impromptu buffet reception, and if we’re lucky the concert will get underway by 9 or 9:30. But everyone seems cool, no-one is demanding their money back, everybody is just getting to know each other. I just phoned Chris, and he reported that their performance in Berkeley last night was excellent. They’re supposed to be doing the same setlist.

We just got an announcement; they are “passing Safeco Field”, so they should be here soon.

This feels very different from Boston….

UPDATE: The concert started at 9; it’s now the intermission. Apparently the delay was due to a 5-hour repair to the plane in Oakland – and then when they tried to push back, the jetway jammed!

But enough irrelevancy. The Tye Missa Western Wynde was just glorious. Well worth waiting for.

That's more like it…

From the BBC:

SECOND TEST, DAY TWO, ADELAIDE: Australia 8-1 v England 551-6 dec
Paul Collingwood became just the third England batsman to score a double century in Australia as the tourists took charge of the second Ashes Test.
He and Kevin Pietersen shared a record fourth-wicket stand, worth 310 when Collingwood fell for 206 on day two.
Pietersen was run out for 158 but Andrew Flintoff helped England reach 551-6, declaring with 10 overs left.
Flintoff then had Justin Langer caught at slip for four in the second over of Australia’s reply in Adelaide.

UPDATE: But… good grief! How could such a wonderful start have led to this debacle???

SECOND TEST, ADELAIDE, DAY FIVE: Australia 513 & 168-4 beat England 551-6 dec & 129 by six wickets
Warne took two wickets and helped in a run out in the morning
Australia won the second Ashes Test by six wickets and went 2-0 up in the series after bowling England out for 129 on day five in Adelaide.

Unprecedented? Absolutely: “No team in history has lost after declaring on a higher total than England’s 551-6 batting first in a Test.”
Oh dear, oh dear, oh dear…..

WiFi update

Just over a week ago I reported that I was having problems with my WiFi network here in the apartment. I think I may have solved the problem. I bought myself a Griffin Technology AirBase, and since then I’ve been getting a consistently good signal.
Griffin AirBase
Basically it’s just a heavy base with a power cord and a slot that the Airport Express snaps into. According to Griffin, it “increases effective range and signal efficiency for your network and AirTunes by raising the base station up into the room. It also makes it easier to check the network status light at a glance.” And it seems to work. I guess that hiding the Airport Express unit away, plugged into a power strip behind the set-top box and DVD player, wasn’t such a good idea….
(Even though the Griffin Technology website will sell the AirBase for $24.99, you can do better. I paid $13.83 at Amazon.com, and some places have it even cheaper.)

Too much of a good thing is wonderful….

Chris blogged that he’s going to see the Tallis Scholars tonight, and mentioned that they’re going to be playing here in Seattle tomorrow, Saturday, at the Town Hall. True, but that’s not the whole story. It turns out that they’re appearing at 8pm on both Saturday and Sunday! On Saturday they’re performing “Renaissance Masterpieces”, and on Sunday “Music from the Sistine Chapel”. What on earth shall I do? Go on Saturday? Sunday? Both?!
