Lake District Long Weekend

Published by David under travel

Over the long weekend we drove up to the beautiful Lake District and stayed in the beautiful Southerdale Cottage.

We managed to avoid the traditional lousy weather that London received and had great weather for a couple of walks from the really excellent Jarrold Short Walks book. We love walking in the Lake District. It’s a long drive from London but it is so totally relaxing it always recharges your batteries.

Castle CragOn the Saturday we had fantastic weather and the walk up to Castle Crag was reasonably busy. We started in the tiny village of Seatoller beneath the terrifyingly bleak Honister Pass; one of the highest passes in Cumbria with a road gradient of 25%.

Castle Crag is less than 1000ft but Alfred Wainright in his Pictorial Guide to the Lakeland Fells described it as:

…magnificently independent, so ruggedly individual, so aggressively unashamed of its lack of inches…

It is thought it used to be an ancient hill fort and it was given to the National Trust by Sir William Hamer in memory of his son who was killed in the First World War. At one time it was a slate quarry and the ascent involves a climb up a huge pile of slate. The summit has great views of Derwent Water and Borrowdale and according to Thomas West in his Guide to the Lake published in 1778:

From the summit of the rock the views are so singularly great and pleasing that they ought never to be omitted.

Derwent RiverThe way back to Seatoller follows the crystal clear Derwent River through Low Hows Wood.

On the Sunday the sky looked a bit rainier so we were practically on our own walking up the beautiful Rannerdale to the spectacular ridge leading to Rannerdale Knotts.

In 1066 the locals of Rannerdale mounted a resistance to the Norman Invasion. Led by the Earl Boethar, the Normans were drawn into the valley and slaughtered by the native Britons. The bluebells that grow in the valley are said to have sprung from the blood of the slain Norman soldiers.

The climb up Rannerdale was windy and occasionally rainy but the view of Crummock Water and Buttermere from the ridge was absolutely stunning. The low grey clouds that were sweeping across the fells made it look like we were staring into Mordor.

Kathryn found a secluded spot overlooking Buttermere just as the sun broke free and the wind became calm. It was the most perfect lunch.Lunch

We also took the time to visit a couple of National Trust properties. On the way up we stopped at Waddesdon Manor - a huge French château dropped into rural Buckinghamshire. Built by the literally minted Rothschilds in the 19th Century on land bought from the Duke of Marlborough it contains an impressive load of the Rothschilds’ fabulous collection including paintings by Gainsborough and Reynolds, Sèvres porcelain, Beauvais tapestries and a large number of French secretaires and roll-top desks. Queen Victoria visited in 1890.

Waddesdon ManorOn the way south we stopped at Charlecote Park; a (very) slightly more modest Tudor manor house on the banks of the Avon near Stratford. According to legend, Stratford’s most famous resident was caught stealing deer from Sir Thomas Lucy’s park and years later he took his revenge by portraying Sir Thomas as the fussy Justice Shallow in The Merry Wives of Windsor.

Like a lot of National Trust properties, Charlecote Park is still lived in by the current descendants of the original Lucy Family. Baronet Sir Edmund Fairfax-Lucy lives there now, presumably in one of those areas we’re not allowed to see. Interestingly, during the depression of the 1870s Henry Spencer Lucy (a crack shot with the 12 gauge) was forced to sell many of the more valuable Old Masters, some to Lionel de Rothschild around 1875.

An open ad network

Published by David under interweb

There is an interesting article on Read/WriteWeb by Sean Ammirati called Google’s Potential Vulnerability - An Open Ad Network. In it, Sean suggets that, despite Google’s huge revenues, they could be vulnerable to the fact that 37% of that revenue comes from ads delivered on sites they don’t control.

While they do have contracts with some of the larger online properties that leverage their ad network, even in that case those networks could switch when the contract comes up for renewal.

Google seems invincible at the moment and Yahoo and Microsoft aren’t making much progress competing against them head-on. But the way to compete against a monopoly is to change the rules of the game. This is what MySQL did with databases and it is what Openads is going to do with the online advertising industry.

Google is still a disruptive force in many areas but it needs to be careful that it’s own disruptive business models are not distrupted by some startup…

Gallery page

Published by David under photography

I finally figured out how to get a proper link to the gallery using the nifty Page Links To wordpress plugin.

So if you hadn’t figured out how to get to the gallery before, check it out.

VirtualBox

Published by David under geek

VirtualBoxOne the very few things that I need Windows for now is JavaME development. The netbeans mobility pack runs under linux but unfortunately all the manufacturers’ emulators require Windows. So now that I have sold my Windows laptop I needed some other way of running Windows. I considered using bootcamp on my MacBook or even repartitioning my linux box to dual boot Windows but I am now using some VM sofware called VirtualBox.

I actually have a copy of VMWare 4.5 but that doesn’t play nice with the latest Fedora versions so rather than pay to upgrade VMWare I am using VirtualBox which is free for personal use. So far it runs really nicely on my dual-core linux machine.

A few things I needed to get it going under FC6:

  • Install the version for all distributions
  • Install compat-libstdc++-33
  • Make sure you put any users into the vboxusers group
  • Mess around with SELinux settings as described here

Mac Zealots

Published by David under geek, rant

Apple have just released minor updates to the MacBook range. I only bought my MacBook a month ago so I guess I’m a little annoyed that I just missed the update but the upgrade isn’t really that significant; a slightly faster CPU and a bigger hard drive, basically.

This guy, on the other hand, is not taking it so well:

Good work Apple. Idiots.

As someone waiting to buy their first Mac I am FURIOUS with Apple and their continued raping of MB buyers.

The MBs are the line of computers that will benefit most from SR and Apple do THIS? I actually cannot believe it. They are absolute bastards.

Oookaay. Repeat after me: calm blue ocean, calm blue ocean, calm blue ocean…

Macs are like that, though. Kind of like a Harley. People either love them or hate them. I guess I’m part of the Cult of Mac now, although I know it’s just a computer.

This is why I wear a helmet

Bike helmet crushed, but head fine

I like this quote:

I didn’t see it coming, but I sure felt it roll over my head. It feels really strange to have a truck run over your head.

Conferences

Published by David under life, mysqlconf07

Ever since I got back from the MySQL Users Conference in California I’ve been wondering how soon I could convince work to send me on another one. It seems every second post in my blogroll is about some conference or another. And it’s not just the cool conferences like JavaOne, either. I find myself reading about the Open Source Business Conference described as:

a great conference for managers, CIOs, execs, investors, lawyers

and I catch myself thinking, “you know, that sounds pretty neat”. Hmmm. I’m sure I’ll get over it.

Gallery

Published by David under photography, travel

I’ve managed to get gallery2 integrated into wordpress in at least a half-decent way. At the moment there is no dedicated link to the gallery but you can get there by clicking on the random picture displayed in the sidebar and then clicking your way around. I suppose you could also click on this link.

There are pictures from my recent trip to California for the MySQL Users Conference in there. Actually they are mostly from San Francisco as there isn’t much to take photos of in Silicon Valley.

If you are wondering what all the pictures of cars are, on my last day I stumbled upon the start of the California Mille. This is a famous classic car rally inspired by the old Mille Miglia (1000 miles) run in Italy from 1927 to 1957. To take part in the California Mille, your car must have either run or have been elligible to run in the original Mille. Not only that, it costs $4,000 and your car has to be chosen as among the best of the applicants.

I was planning on killing the few hours before my flight by sitting in the lovely park at the top of Nob Hill but as I arrived at the Fairmont Hotel I was greeted by the sights and sounds of rows of Alfas, Porsches, Fiats and Ferraris. There were some amazing cars there including quite a few gull-winged Mercedes 300SLs, a strange Fiat 8V from Australia, and an absolutely stunning Ferrari 250GT California. So I spent the next couple of hours taking pictures of cars until my batteries died.

Birkbeck MSc CS Prize

Published by David under geek, life

Man, I just keep surprising myself:

——– Original Message ——–
Subject: MSc CS project prize
Date: Fri, 04 May 2007 11:59:01 +0100
From: Szabolcs

Gentlemen,
As you may know, each year we choose the best MSc CS project.
This year, your projects were shortlisted.
Well done to all of you and congratulations to David for the win.
David, could you please send me your current address so that
I can send you the prize (a cheque for £100).
Hopefully, you will find the comments below useful.
Regards, Szabolcs
