Broad Rock

May 26th, 2009

A few weeks ago I did a long walk on Dartmoor with my dogs. We started from Sheepstor and took the path to Ditsworthy Warren House. From there we walked up the Plym to Plym Steps and across to Broad Rock. The problem was that I couldn’t actually find Broad Rock! This nagged at me so much that last Saturday I did another walk, starting at Whiteworks and this time I did find it.

Actually I found it the first time and didn’t realise it. The writing on the rock “BB Broad Rock” has grown so faint as to be almost illegible. For my record and no doubt for others trying to locate it, it’s at N50°29′19.2″ W3°56′54.7″ (SX 61849 67244).

From Broad Rock we walked to Erme Head and then followed Blacklane Brook to Ducks Pool. On the OS map there appears to be a path from here through Foxtor Mire back to Whiteworks. For those who don’t like wet feet, don’t even try it. There is no path! I thought I was somehow missing it until I stumbled upon a Dartmoor Letterbox where the book was filled with various comments from people also trying in vain to find it. In the end we cut across rough moors to Nuns Cross Farm and followed the path from there back to Whiteworks. Total distance was exactly 10 Miles.

May 25th, 2009

Following the success our Narrow Boat holiday, I got a bit obsessive and started looking up other good circular routes. Living where we do in Cornwall, one annoyance is the currently unnavigable old Stroudwater Canal and the Thames & Severn Canal. Both of which are in the process of being restored and renamed as the Cotswold Canals by the Cotswold Canals Project.

I spent some time creating a Google Earth map of the Cotswold Canals, and emailed it to the project but sadly didn’t receive a response from them. I’ve included it here in case anyone else is interested.

First ever narrowboat holiday

May 11th, 2009

Lou and I did our first ever narrowboat holiday last week and it was a great success. We were accompanied by Kieran and his girlfriend Becky and my parents for a total of six with an age span of almost 65 years. For such a disparate group to all have a good time is a strong testament to how relaxing such a holiday can be!

Now I’ve received vouchers for 25% discount if I book another canal holiday for this year. Lou and I would love to do this and are in the process of trying to find four friends who fancy spending a week plodding along in a boat. Six people seems to be good number and works out (with discount) at about £150 per person for a week in September. If you know Lou or I and are interested, please get in touch, it’s good fun, honest!


For the record, this is where we spent each night whilst we travelled around the Stourport Ring. The last night (Friday) was spent in the docks from which we started.

The wonderful Western way

February 27th, 2009

Time for a rant on a subject I know nothing about.

I’m sure I’m not the only person in the UK this week who feels quite strongly about the Sir Fred Goodwin issue. To the layman it seems as though Sir Fred, the chairman of The Royal Bank of Scotland steered his great company into the largest UK corporate disaster ever and is now being rewarded for his fine efforts with a £16m pension pot. Owing to the magnitude of Sir Fred’s cock up, the poor chap has been forced to retire early and will subsequently be drawing his £650k annual pension from the ripe old age of 50!

Did I let a hint of sarcasm creep in there? It’s hard not to. Sir Fred will continue to lead a life of the utmost luxury. His earnings from RBS in 2007 alone amounted to £4.2m, a sum that most hard working, honest people can only dream of earning in a lifetime. Others are not so lucky: The poor employees of RBS are facing up to the realities of their bosses mismanagement. Many of them are soon to be unemployed; like wartime cannon-fodder, they are simply a statistic that Sir Fred can read about from the comfort of his ivory tower.

At the moment the Government is making lots of noise about Sir Fred but I can’t help feeling that the root of the problem is the Western “fat-cat” philosophy where company directors seem to decide their own value to the business and reward themselves accordingly. I don’t care how clever Sir Fred was, he broke his bank, left the taxpayer with an eye-watering bill and his employees to pay with their jobs. With great responsibility should come accountability and if that were the case, Sir Fred would be going to prison and his personal wealth to help those whose lives he’s irrevocably damaged.

What’s Up Net?

February 13th, 2009

Since converting my home network to DHCP, I’ve been struggling to keep track of what devices/addresses are in use. Not because I’m poor at record keeping but rather because three teenage kids in the house like messing about with their PC / Hecksbox / Wii configurations. The following command came to my rescue.
nmap -sP subnet/mask
Running it as Root provides additional MAC details. Very useful!

Nine Dart Finishes

January 27th, 2009

I felt a need for distraction from work for an hour so I wrote a Python program to calculate the possible ways to do a nine dart finish in a standard game of 501. There are 3944 possible ways to do it so I won’t list them here.

The initial code attempt required 4,585,142,217,282,816 iterations, that being the total possible combinations of 9 scoring darts with a double or bull to finish. This would have taken a long (read: very long indeed) time to run but fortunately many of the iterations can be discarded because they would make it impossible to reach the target of 501. For example, if you hit a one with the first dart, there’s no point worrying about the next eight darts, you’re not going to make it.

After discarding the impossible iterations, 459,514 loops were required. This reduced the required time to around 5 seconds on my Athlon64.

Trivia

  • It’s impossible to do a nine dart finish without hitting a treble 20. In fact you must hit at least three of them.
  • There are 288 ways to do it without using 18’s or 19’s but all of them require 17’s.
  • The lowest scoring dart you can throw (in the first eight) and still be left with a finish is 34 (D17).
  • The lowest double you can finish on is D12
  • 2,296 of the 3,944 solutions require finishing on the Bull.
  • The only possible finishes besides the bull are: D12, D15, D17, D18 and D20
  • It’s not possible to do a nine dart finish with more than one double in it.
  • There are 540 ways to leave a maximum 170 checkout
  • A nine dart 503 has over three times as many possible combinations as 501. 12,472 of them in fact.

Thanks to new government legislation…

January 27th, 2009

At the moment I seem to get at least one call a day from companies claiming they can help me with my debts because new government legislation means they can freeze what I owe. To begin with, I don’t believe this. If it was that simple, everyone with a credit card would jump on the band wagon and watch their debts magically disappear. The second thing is that if I wanted help with my debts then I’d ask for it. I don’t need (or want) offers of assistance from fly-by-night companies I’ve never heard of.

I was finally driven to write this rant after a call today from DSN (The Debt Support Network). What made their call exceptionally annoying is that it was pre-recorded blurb with an option at the end to “Press 6 on my keypad to solve all my debt problems”. As I’m registered on the Telephone Preference Service, I shouldn’t be getting calls of this nature. I mean who in their right mind is going to place their finances in the hands of a company that pedals itself through illegal phone calls?

Garmin GPS

January 26th, 2009

Last year I treated myself to a Garmin GPS. Being someone who is often trying to find a city-centre hotel in the dark, in the rain, during rush-hour, this device quickly proved to be heaven sent. Being a bit of a geek for gadgets, I installed all the associated Garmin software on my PC and frequently checked for available updates to my Nuvi250W. To date the only updates I’ve found have been to textual English language files.

At the beginning of 2009, I switched on the GPS and it warned me that my maps were now over a year old and that I should update them. Obviously something wasn’t working to plan as I’d frequently been told by Garmin’s software that there were no updates for my unit. As I live in Cornwall it was obvious that updates were required as the A30 bypass of Indian Queens near Newquay had caused me considerable grief. My GPS thought I was driving cross-country and subsequently lost the plot, (quite literally) and subsequently deposited me in a maze of twisty little roads, all alike.

Finally today I found the cause of the problem; I needed to subscribe to map updates before the Garmin software would even advise me that they were available. In other words, there were no updates available for my Nuvi250W GPS as I hadn’t paid for them. Further clicking around Garmin’s website led me to the required item, Lifetime Europe Map Updates priced at £99.99. Wow, that’s a lot of money for updates to a device that only cost £150 in the first place! The other point to note is that “Lifetime updates” doesn’t mean my lifetime, it means the product lifetime. The updates are tied to the serial number of the device so in a few years time, should I want a newer GPS, I would need to buy another Lifetime Europe Map update.

This all strikes me a dreadful profiteering on the part of Garmin. A quick visit to Google Shopping reveals that I can buy a brand new Nuvi250W from Tesco for less than the map update. In this day and age when we’re all supposed to do our bit for the environment, having a high-quality product like this turned into a annually disposable item by the price of software updates is ridiculous.

I am a Spammer!

December 24th, 2008

I must be a spammer because SORBS say I am. I didn’t realise it until today when I tried to email the administrators of a Usenet Peer and the message bounced because their Mail Server uses SORBS (Spam and Open Relay Blocking Service).

SORBS have a good website so it didn’t take long to find out that my host had been listed because it relayed an email to a SpamTrap. I had to ponder this for a minute before it occurred to me that the server in question runs a Nymserver. This means that any user of that service could have maliciously or accidentally emailed one of these SpamTrap addresses.

Okay so it’s a mistake on the part of SORBS, I’m not really a spammer and one email sent to an address certainly doesn’t qualify me as one. Unfortunately that’s not how SORBS see it; it’s my fault I got on their list and it’ll cost me $50 to get de-listed. That’s funny! They want me to pay to get off their spam list. What a lucrative little venture, no wonder they make it so easy to get on their list in the first place.

So to sum up:

  • I’m listed on SORBS and I’m not going to pay to get off it. Internet blackmail is distasteful.
  • People who rely on nothing but SORBS to vet their email will be dropping legitimate email, mine. Serves them right for letting a third-part like SORBS control their services.
  • It seems that Spam, (like Viruses) is now a lucrative business, not just for the perpetrators but also for those who claim to cure it.

Update 25th Dec 2008
This morning I got a email reply from SORBS, I’ve been de-listed! The single email to the Spamtrap that caused the listing has expired and subsequently my enquiry was enough to warrant a de-listing. Very kind of SORBS but it doesn’t really make their practises any more palatable to me.

GameCopyPro Scam

October 29th, 2008

Woe is me! I thought I was too experienced to get caught in a simple Internet scam but I fell for this one, hook, line and sinker.

Kyle (my stepson) reported this morning that his Xbox360 was scratching disks. As the games he plays cost around £45 each, this seemed a serious issue and so I did some investigating. It appears that he’s far from alone, XBox360’s have a well documented history of scratching disks. I decided the solution was to get some software that would enable me to backup his games. More Google searching led me to www.gamecopypro.com which seemed to be a well linked and recommended solution for copying video games. The $29.99 price tag was also quite appealing and so I bought it though Paypal.

As with many software purchases, I received an email within a few minutes thanking me for subscribing. The unusual thing though, no link for downloading the software. After some bemused clicks around the members area it quickly became apparent that I’d been scammed. There is no such thing as GameCopyPro, it consists of nothing but vague info on how to backup games disks.

After yet more Google searches I soon learned that I was not the first to be tricked by this outfit; there are loads of references to angry people who lost their money just like me. The reason GameCopyPro seems to rate so well on reviews is their Affiliate Programme. Every referral to their website that results in a sale earns the referrer 75% of the sale. Neat trick!

I’ve now launched a dispute through Paypal to try and recover my money on the grounds that the product I bought doesn’t actually exist. According to Paypal, my dispute is forwarded to ClickBank who presumably provide payment services for GameCopyPro. I’ll update this blog entry if there’s any progress.

Update 9th Nov 2008
Score one for Paypal and another for Clickbank. Seems that the dispute process actually does work and my entire charge was refunded. Based on this episode I’ll be considerably more disposed to use Paypal for payments in the future. Now if only GameCopyPro’s website would be forced to close for being the nasty scam it is, all would be well.

Farmers Law

October 13th, 2008

A few incidents yesterday got me thinking about the law and farming. Somehow the farming community seems to be a law completely unto itself, exempt from the rules that apply to other folk.

Sunday was the annual sponsored walk supporting Teenage Cancer Trust. It was a lovely day on Dartmoor but for me was slightly tainted by being forced to keep my dog on a lead for 10 miles because of grazing sheep. Why are farmers allowed to keep sheep in our National Parks whilst being paid to keep their own fields dormant? It’s mad!

On the same day, whilst walking up the old Princetown railway line, a young child on a Quad-bike passed us at a ridiculous speed. How on Earth is a quad-bike allowed on a cycle trial? Because the law exempts farming vehicles and their users from restrictions that apply to other drivers.

Lastly, on the same day newspapers report this article of a dog being shot. Not for worrying sheep, but cows. This was a boxer dog not a man eating tiger, geez! The police response to this, “A police spokesman said there were no independent witnesses and, as it was deemed a civil matter rather than a criminal offence, there would be no further police action.”. What a load of bollocks. Seems that like the ban on hunting with hounds, the police put cases like this in the “too difficult” tray.

Recursive chmod

October 10th, 2008

My music collection is complicated, I rip my CD’s on a Linux server, FTP them to a Windows server. Manipulate ID tags and filenames using various means, then FTP them back again in order to play them through my Squeezebox. This recently caused me grief when I used an incorrect umask on a massive transfer, resulting in incorrect file permissions on directories and files.

Using recursive chmod to correct this is tricky as file and subdirectory permissions need to be different, in my case, 644 for files and 755 for directories. These two commands solve the problem:

find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;

0845 0262572

October 3rd, 2008

Yet another number that’s been calling my mobile on a daily basis over the last couple of weeks. This one belongs to Phones 4U, a company in the UK mobile phone industry which firmly believes in the hard sell ethos. At the moment they aren’t going to sell me anything because despite calling me many times I’ve yet to hear a voice on the other end, they just hang up.

I think I was with Phones 4U when I first took out a Vodafone contract, many years back. In 2003 Vodafone thought better of that arrangement and dealt with me directly instead. Needless to say I got a much better deal from then on. Looking at their website now it’s pretty obvious they are still unable to offer Vodafone. Score one for Vodafone for not being associated with their nasty hard-sell tactics.

Phones4U was owned by high-profile, corporate tough-guy John Caudwell. He sold them in 2005 and I’m not sure who owns them now. Don’t really care either, I just wish they’d stop calling me!

Gallery2 Captcha

September 25th, 2008

Having recently cleaned out all my comment spam from Gallery2, I’ve been wondering how it got there in the first place. In order for non-authenticated users to leave a comment, they must first answer a Captcha. Having tested it’s working correctly, I’m forced to conclude that somebody has a bot that can successfully read and reply to the Gallery2 Captchas.

As of this time, I can’t find any information on replacing the Captcha images with other versions. Obviously if all Gallery2 users have identical Captchas then it’s well worth the spammers time and effort to automatically handle them. There are after all only 10 possible digits. If anyone has info on replacing the stock captcha set with others, I’d be pleased to hear about it.

Gallery2 Comment Spam

September 25th, 2008

I store all my photos in Gallery2 with a PostgreSQL database back-end. It works well in most respects but fails miserably when it comes to managing Comments. Whilst it’s possible to delete them, it can only be done one at a time; a painfully slow process when there can be tens of thousands of spam comments. This little PostgreSQL script can take the pain out of it:-

SELECT g_id INTO TEMPORARY tmptable FROM g2_comment WHERE
g_host='189.59.236.131' or
g_host='159.148.82.3' or
g_comment like '%http:%' or
g_comment like '%url=%';

DELETE FROM g2_entity WHERE g_id IN (SELECT g_id FROM tmptable);
DELETE FROM g2_childentity WHERE g_id IN (SELECT g_id FROM tmptable);
DELETE FROM g2_comment WHERE g_id IN (SELECT g_id FROM tmptable);
DROP TABLE tmptable;

This should only be treated as an example but it provides a good foundation to work from. Bulk comments often come from common IP Addresses so the g_host entries can be used to handle that without too much pain. The g_comment fields match comments that contain http or url entries. As none of my good comments contain links, these are my ultimate Spam comment killers.

Disposable Society

August 4th, 2008

A few years ago I bought a cordless drill/screwdriver from Focus, a big UK DIY chain. It’s a 24v model CCHD24 made by a company called Champion and it’s served me very well. Now the battery is failing to retain a charge and I want to replace it. The problem is that I can’t find a reference to it anywhere on the Internet, it’s as if the damn thing never existed!

Besides having a model number of CCHD24 (the CCHD presumably being Champion Cordless Hammer Drill), it has another reference of SKU484817. I’d love to hear from anyone who’s succeeded in getting a replacement battery for one of these.

What the Hack - The sequel

July 30th, 2008

I can’t believe it’s four years ago that I went to What The Hack at Liempde in Holland. Now it’s almost time to dust off the rucksack and check out the tent in preparation for Hacking At Random.

Anyone fancy tagging along? It’s fun, honest!

00800 2794783

July 30th, 2008

This is the number that shows up on my caller display when Monument try to get in touch with Lou. My issue is that they try and contact her every couple of hours, every day and seemingly take no notice of me telling them she’s at work.

Are there phones available that enable me to block certain numbers? If such phones exist then one is going on my shopping list. Monument will have the honour of being the first name on it.

Update - 14th Aug 2008
Since writing that article, not a single day has passed without at least one call from Monument. I mean, how much harassment can these people legally throw at me?

Motorcycle Road-Tax Petition

July 28th, 2008

I’d love to see a lot more names on this Government petition. Why on earth should motorcycles be exempt from tax relief for non-polluting vehicles?

In summary:

Changes to the law mean cars emitting less than 100g of CO2 per kilometre travelled would be exempt from paying Vehicle Excise Duty (road tax), while motorcycles are still required to pay.

The age of the bus

July 24th, 2008

For the younger generation, the title of this is based on an old series of advertisements for British Rail, their slogan was, “This is the age of the train”. Thought I’d better clear that one up. :)

Fuel prices being what they are at the moment and the associated costs of actually owning a car in the first place, the bus would seem like a great alternative for local transport. I’d like to dispense with one of our two cars so this morning set about investigating a season ticket for getting our two kids to work and/or college.

Our local bus services are provided by First Group which sours the milk a little before I start. These are the guys that run First Great Western trains. My experiences of this service are comprised of consistantly late trains and a parking ticket. I’ll try to remain subjective and not let my previous experiences impair my judgement.

First issue of the day is location. I can’t use a Plymouth season ticket because we live outside the boundaries of Plymouth. A Devon card covers Devon and a Cornwall card covers Cornwall, but neither of them is suitable for travelling the 15 miles between my home in Cornwall and Plymouth in Devon. Fortunately there is a South-West card that covers Devon and Cornwall.

The FirstDay South-West Ticket costs £6.60 which is not only very expensive for such a short daily journey, it’s also useless, not being valid before 0845. To overcome this I need a Peek South-West Ticket at £7.30. Clearly the daily ticket is a waste of time, the annual cost of travel (based on travelling 5 days a week for 46 weeks a year) would be £1,679. If my partner Lou and her two eldest kids did this every day we would have an annual bill of £5,037. Clearly not a practical option compared with using a clapped-out old car.

Next on the agenda is a Devon and Cornwall FirstWeek Ticket. This one weighs in at £31 per week which based on my 46 weeks per year calculation works out at £1,426 per person or £4,278 for my three people. Score another for the high-poluting, road-congesting and clapped-out car.

Perhaps these options appear a little biased, why would I elect for a daily or weekly ticket when I’m looking at travel over the period of a year? Well the reason is that First Group don’t appear to offer any ticket options longer than a week that cover the 15 mile journey from St Mellion to Plymouth. Perhaps I’d best enquire, perhaps their website isn’t comprehensive. I sent them a message using their enquiries service.

Hello,
I’m looking to buy a season ticket for travel between St Mellion and Plymouth using the 76A service. Please can you advise me of the most cost effective yearly tickets for travel on this route at peek times?
Many thanks,
Steve

Now I’ll just have to wait for an answer.

Update - 24th July (Next Day)
I received a helpful reply from First today.

Dear Mr Crook

Thank you for contacting First Devon & Cornwall regarding the fares for annual passes for the service 76a.

Unfortunately we do not do a yearly pass from Cornwall but there is a monthly pass at the cost of £86.00 that you would be able to use to come into Plymouth to your destination and return but would not be able to use it on any other service in the Plymouth boundary.

I hope this information is useful.

Yours sincerely

[Name Scrubbed]
Customer Service Advisor

Okay, so there is a missing option on First’s website, an £86 monthly pass. Assuming I need travel in all 12 months of the year, that’s £1,032 per year, per person. I guess this makes the bus a feasible option where only a single person can use it as an alternative to car transport. Using my example of three people, the bus would cost them £3096. This really doesn’t strike me as a viable alternative. In an age where the roads are far too congested and petrol prices are rocketing, it’s a pity there isn’t a better carrot being dangled to encourage people to use bus transport. It’s never going to be as convenient for people as going door-to-door in their own car so that carrot needs to be big and juicy. Today’s season ticket carrot is small and tasteless.
