Sapper Holland – Lest we forget #RemembranceSunday2018

Thinking of my great grandfather Frederick Arthur Holland from #Weymouth who died during #WW1 #RemembranceDay2018 when my wonderful Nannie Elsie Leah Reynolds was just 4 years old 😭❤️😭

My great grandfather Sapper Holland died aged 32, the same age as my sons are now, my grandmother Elsie was 4, almost the same age as my grandson Felix is now. It just doesn’t bear thinking about😱

My grandmother grew up in very reduced circumstances with her mother working 3 jobs just to provide enough food to eat.

And despite being a fun loving and funny person always carried sadness in her heart from her father being taken away from her at such a young age 😭❤️😭 #WW1 #RemembranceSunday2018

70th anniversary Enigma reunion at Bletchley Park in 2009 #Bpark

8 years ago today was the 70th anniversary Enigma reunion at Bletchley Park.
The the wonderful Maggie Philbin and many other awesome people Christian Payne, Kate Arkless Gray, Benjamin Ellis, Hannah Nicklin, Matt Rawlinson and Steve Lawson, came up to Bletchley Park with me to interview as many veterans as possible to capture their memories of their time working on cracking the codes during WW2.
Here with Maggie is the phenomenal codebreaker Captain Jerry Roberts RIP, wonderful man and great family friend.

We had an absolutely wonderful day with the hundreds of veterans that came along spending the whole day capturing as much as possible for posterity.
I had started a campaign to save Bletchley Park the previous year in July 2008 and met quite a few veterans, but this was the first time that I really got to meet hundreds of veterans and hear at first hand so many of their amazing stories.
Here are some photos from the day taken by Benjamin Ellis and Steve Lawson. There are many more, check out all the #bpark70 pics from the day on Flickr.
Here are a few of the interviews conducted that day in 2009.

I chatted to Hannah, giving an overview the day and speaking about the amazing discussions we had all had with the veterans.

Christian Payne interviewed many veterans on the day. Here are just some of his interviews. Enjoy 🙂

Interview by Christian with Bletchley Park veteran Margaret Warner of the WAAF:

Need an inspiring and motivating tech speaker in Sept/Oct 2017? #tech #disruption

CALLING US BASED FRIENDS!! Need an inspiring and motivating tech speaker in Sept/Oct 2017 or know someone who does?

I’m going to be in Orlando Florida for the annual Grace Hopper Conference from 3-6th October. If you are in the US and would like me to speak (paid, but without travel costs from the UK) in the week before or after those dates please do get in touch. I need to book my flight to Orlando next week, so a quick heads up would be great. More details about me on my speaker page:

Dr Sue Black OBE 

Dr Sue Black is always a riveting speaker, with informative content and a personal warmth which makes her a pleasure to listen to. She has a clarity and an ability to get to the heart of something and in simple language which makes her a rare
person.

Baroness Rennie Fritchie, House of Lords

I highly recommend Sue as a speaker. When she spoke at our Leadership Academy for young women in Tech she received brilliant feedback. The audience loved her honesty and advice on how to get on in business whilst remaining your authentic self.

Karen Gill, Owner, Everywoman Ltd.

Sue is a delight to work with, full of enthusiasm, extremely knowledgeable … one of the most inspiring people I’ve met in along time.

Computation of Ripple Effect Measures For Software #softwareengineering #softwaremeasurement #rippleeffect @LSBU #PhD #2001

How exciting!! I just received a digital version of my 2001 PhD thesis “Computation of Ripple Effect Measures for Software” from the British Library. If you would like to read it, here you go:

Sue Black – PhD thesis 2001

phd cover sue black

If you would like to read something a bit shorter here’s the Abstract:

There are many measures of structural complexity of source code, of which ripple effect is just one. Ripple effect measures the amount which a module or program may affect other modules within a program, or programs within a system, if changes are made. Measurement of ripple effect has been incorporated into several software maintenance models because it shows maintainers the ramifications of any change that they may make before that change is actually implemented. As such, computation of ripple effect provides a potentially valuable source of information. The aim of this thesis is to show that an approximation to Yau and Collofello’s ripple effect algorithm can satisfactorily replace their original algorithm as a measure of structural complexity.

The basis of our approach has been to completely reformulate the ripple effect calculation using matrix arithmetic. As well as making the calculation more explicit the reformulation reveals how the algorithm’s structure can be broken down into separate parts. By focusing on the derivation of one particular matrix we find that an approximation may be made, greatly simplifying the calculation.

A Ripple Effect and Stability Tool (REST) was created and used to validate our work. Firstly, a comparison of the original and reformulated ripple effect measures from several programs shows them to be highly correlated. Secondly, a case study is used to explore the link between ripple effect and maintainer’s intuition of the impact of code changes. Perhaps unsurprisingly, this link appears to be less than clear-cut.

“Raymondos” – an exercise in writing dialogue – Arvon non-fiction course 2017 at Totleigh Barton

“Raymondo’s” – original version

My nan was great fun to be around. When my brother and sister were small she used to pretend that they were top hairdressers in their salon called “Raymondos” she would get all of her hairdressing accoutrements out of the cupboard and Sarah and Stephen would do her hair for hours on end. Or so it seemed. I would be sitting on the sofa watching and chatting and reading a book. Probably something by Enid Blyton.

Nan had loads of hairdressing paraphernalia: grips, clips, Vitapointe cream (which I can smell now as I write about it), curlers, pins, brushes, combs, setting lotion and papers. I must have joined in too sometimes as I can remember putting Vitapointe on my nan’s hair and then brushing her hair with a bristle brush. It makes me smile to think of those times.

“Raymondo’s” – dialogue version

I was at my nan’s flat with my brother and sister, Sarah and Stephen who were around 5 years old, playing hairdresser’s with my nan.

“Now Raymondo, I’d like a shampoo and set. Please give me a lovely hairstyle, I’m off to a ball tonight in my best frock and I want to look beautiful.”

“Yes, nannie. I’ve got the brush, I’m going to brush your hair and make you look lovely.”

“Now Cynthia, can you please help Raymondo with the setting lotion and papers”

“Yes nannie. Raymondo here you are.”

Sarah picks up the packet of papers and the setting lotion ready to pass them to Stephen.

“Can I have the lotion please Cynthia” Stephen said with a giggle, delighted to be calling his twin sister by a made up name.

“Here you are Raymondo” Sarah replied and handed over the lotion, accidentally squirting some of it over nannie’s dress.

“Oh no! Raymondo, Cynthia, you are such naughty hairdressers!”

I looked up from the sofa and we all burst into laughter.

Many thanks to Arvon Totleigh Barton, Lois Pryce and Sukhdev Sandhu for a wonderful week.
