Using A Digital Signature With Outlook

Introduction

This article covers some of the issues involved when using a Digital Signature. Each Digital Signature is generated from a Digital Certificate (otherwise known as a Digital ID) issued by a certifying authority.

All examples given are created using Microsoft Outlook 2010 on a PC using Microsoft Windows 10, but the principles apply to other versions of Outlook and other email clients.

This article has been written to compliment my previous article Make Safe Financial Transactions.

Anyone using an Apple Mac can get appropriate certificate information in this article published by TechRepublic entitled: How to configure digitally signed email in Apple Mail.

Lighting Charts – Which Lamp Do I Need?

Introduction

We are all trying to reduce energy costs and CO2 emissions by choosing modern alternatives to incandescent lamps. Here are some lighting charts to help you select the best lamp for your situation. Since the decline of incandescent lamps there have been many alternatives made available based on fluorescent tubes bent in many ways to condense a long tube into a confined space.

I had my first Philips SL prismatic Compact Fluorescent Lamp (CFL) lamps soon after they came on the general market back in the 1980’s. I only recently sent my last one to recycling after deciding that even my shed could do better than have one of those long time warm-up devices.

Fluorescent Tubes

In the early days of low energy lighting there was nothing better than the good old fluorescent tube, usually confined to kitchens and garages in the British house. I still had two twin fluorescents in my kitchen until 2015. If you want the room lit without shadows that’s the way to do it. After much searching in 2003 I found some streamlined fluorescents fit for the modern era to replace my old fluorescent ‘chunky boxes’. Unfortunately they went off the market and I struggled to find a decent looking replacement that didn’t cost a fortune. There were some problems with the ones I used. They had a self destruct mechanism built-in. The plastic fixings for holding the wires in place on the frame all deteriorated under the ultraviolet light given out by fluorescent tubes. I replaced them with zip ties but they suffered from the same problem.

Lamp Brightness

To get back to the point of this article, which is to advise on the brightness of replacement lamps, I have chosen to publish a chart by espares lighting chart which seems to relate to the UK/European market and another by ovo-logo which relates to the American market and appears to suggest their lamps emit more light than European lamps, e.g. UK/European 100W ≅ 1300 lumens, American 100W ≅ 1600 lumens (see A USA Lighting Chart).

WordPress Fatal Error Out of Memory

How I Resolved ‘Fatal Error Out of Memory’ For A Single Post

After much editing  of my WordPress post entitled ‘How A Toilet Silent Fill Valve Works’ , since I wrote it in May 2014, (there must have been at least 150 edits, and I changed it from a page to a post too) I suddenly had this ‘Fatal Error Out of Memory’ script on the WordPress White Screen of Death when I tried to edit it:

Riding The North Norfolk Railway

The North Norfolk Railway

The North Norfolk Railway (NNR), known as The Poppy Line, runs from Holt to Sheringham via Kelling Heath Halt (for Kelling Heath Park) and Weybourne. A total distance of 5¼ miles. My wife, dog Leo and I road the rails there and back from Holt on 10th April 2014.

You can No.76034 having recently arrived at Holt in the featured image here.

The line runs along the part of the North Norfolk coast but stays inland from Holt to Weybourne. After Weybourne it runs nearer the coast on its way to Sheringham. A map of the line is available at http://www.strollingguides.co.uk/ and the line is  highlighted here on Google Earth (which must be installed to see it).

Mira Shower Thermal Switch Replacement

Introduction

This article advises how I have replaced a Mira Shower thermal switch in a MIRA Sport 9kW Thermostatic Shower on several occasions.

Originally I installed a MIRA Sport 9kW Thermostatic Shower as part of a new bathroom and had it tested and certified by a qualified electrician on 1st May 2007. I was very pleased with it and it worked well for three years until June 2010 when it developed a fault.

I found that in the middle of taking a shower the water would go cold for a few seconds and then get warm again. On the first few occasions I wondered if cold water being drawn off by other taps and appliances was lowering the water pressure to the shower and so causing it to operate incorrectly (although the low pressure light was not illuminating). As the days went by the problem got worse and my wife ended up washing shampoo off with cold water. I knew then that I would be in bad books until it was fixed.

I had to determine if this fault could be fixed or if I would have to replace the entire shower unit. For this I needed to take a look inside the shower unit.
