My wife and mother-in-law both prefer a long thin calendar like this in A3 format so that they can easily make notes on it (see featured image). My wife’s hangs around the coffee table all the time. She doesn’t want to bother with an electronic one, although she has that option. Her mother has a similar one lying around in the corner of her kitchen worktop with a pen at the side. It’s very easy to scribble daily items down. There’s no shortage of room on it. Any extra notes can always be written on the back of the pages.
As the months tick by the pages can be folded over at the top so that the next month becomes visible but the past is not thrown away. Do you want one? Then read on and I will explain how to download one for any year in your lifetime and print it out. Continue reading “Print A Long Thin Calendar For Any Year”
A recently discovered Backdoor Trojan Regin is a computer bug found by the software security company Symantec. Its purpose is to spy on the activities taking place on computers. It can collect passwords, capture screen images and even recover deleted files.
The Backdoor Trojan Regin has been made to operate in five stages the last two being encrypted to make it very difficult to discover and understand. If any stage were to be discovered it would say little about the other stages. Two stages are specifically given over to loading each other and the other stages. You can see a block diagram of Regin’s stages of operation at this Symantec site.
Backdoor Trojan Regin appears to have been developed as far back as 2008 and by its sophisticated nature was probably developed by a nation state as opposed to criminals. It appears to have been withdrawn from use by its masters in 2011 and a new version reintroduced in 2013.
Regin infections have been found in the following countries:
- Russian Federation
- Saudi Arabia
All Regin infections have been shared by these sectors thus:
- Airline – 5%
- Energy – 5%
- Hospitality – 9%
- Research – 5%
- Small Businesses & Private Individuals – 48%
- Telecoms Backbone – 28%
The Backdoor Trojan Regin has been made extremely stealthy so that it is very hard to determine what it is up to even after discovery. It could go undetected for years. For those interested it uses RC5 encryption which isn’t commonly used.

If you didn’t already know it the 1st January next year will always be on a different day to the 1st January this year. This comes about because:
- for ordinary years with 365 days there are 52 weeks and 1 day remaining,
- for leap years with 366 days there are 52 weeks and 2 days remaining.
This means that:
- if the 1st January is on a Monday in an ordinary year then so is the 31st December. So the next year must have the 1st January on a Tuesday,
- if the 1st January is on a Monday in a leap year then the 31st December is on a Tuesday. So the next year must have the 1st January on a Wednesday.
If there had been 364 days in every year the 1st January would always be on the same day of the week.
As a consequence of all this movement around the week, by the 1st January, next years calendar is always different to this years. That leads to the question: “There’s only seven days in a week so how many different ones do we need? Just seven.” Well the answer is, “No, you need another seven as well, for all the leap years. They too can start on any day of the week.” Continue reading “Fourteen Different Calendars”
It was a nice summer and I enjoyed a family day out travelling from Hythe to New Romney on the Romney, Hythe & Dymchurch Railway (RH&DR) in Kent on 5th July 2014. We travelled on an overcast afternoon and the breeze was slightly chilly when it whistled through the carriages. We travelled West from Hythe as far as New Romney, where we alighted to look at the model railway and take refreshment.
The original plan was to go all the way to Dungeness, part of Romney Marsh1, where the line ends. It doesn’t end in the usual sense with buffers at the end of the rails. The outbound line loops around the countryside until it becomes the line running back to Hythe. Trains don’t have to manoeuvre to make the return journey. They just keep going forward.
There is a Railway Station at Dungeness too besides a lighthouse, village, very large shingle beach and a Nuclear Power Station.
Unfortunately we travelled too late in the day. We realised that if we continued our journey, from New Romney to Dungeness and back, we wouldn’t have time to get back to Hythe. Perhaps I’ll get to see Dungeness next time.

It was a wet day this year at the GCR Winter Steam Gala 2013 (on 27th Jan). I didn’t take so many photos and the videos were short. For the most part the videos are of trains leaving stations. The event ran all day but I only arrived in the afternoon. Here is the Featured Image of No.6023 ‘King Edward II’ for those who can’t see it.

The Problem To Be Solved.
A good friend of mine had found that an Excel spread sheet no longer had a formulae in a particular cell. It had a number there instead. This meant that any changes in other cells associated with the missing formulae had no effect on the result in the TOTAL column. He wanted to go back to a time when the spreadsheet had the correct formulae in it. He had many backup files and feared he might have to examine each file until he found when the problem occurred. So I advised him of a quick way to examine his backups using a binary chop method to look at just a few critical files. Continue reading “Manual Search Using Binary Chop”
This article advises how to perform Dyson Slim DC18 Cleaner Head Maintenance. This can involve removing the Brushbars to remove items that have got wrapped around them and removing the Soleplate for access so dirt can be cleaned out. In extreme cases the Motor Housing can be opened so that dirt can be sucked out of it too. Continue reading “Dyson Slim DC18 Cleaner Head Maintenance”
