I can remember sitting in class and hearing the teacher saying “Hemingway! Stop day dreaming and looking out of the window!”. Forward many 10’s of years to the weekend just gone and my optometrist saying, “Mr Hemingway, You need to look out of the window more!”
Sitting in front of a computer screen all day has caught up with me. Especially driven in recent times with video calls.
So why look out of the window more, Meibomian Gland Dysfunction (MGD) is when the eyelid glands don’t produce enough oil to stop the watery layer of the tears from drying out. You don’t blink as much when your looking at the screen for a long time. There are a lot of other factors that can play into or cause MGD, however screen time is the most likely for me.
I have a mild case which is treatable with a warm flannel or warmed Eye Bag and some gentle massaging eyelid to help release the tears as its been caught early enough. If left and nothing done could become more serious in time.
The exercise I was given is a 20:20:20 – look out of the window every 20 minutes at something more than 20 yards away and blinking 20 times.
Taking regular breaks is a must, even if to look out of the window regularly.
A timer on the desk now counts every 20 mins so I can get a reminder when head down in a screen concentrating.
Screens are one of the most the in demand repairs that are carried out today. In some cases the phone can only be repaired by a manufacturer or authorised repairer. Cost is always a factor and some look for cheaper options or the ability to repair it themselves.
The ability to purchase spare parts for mobiles has been available for a long time from online places like eBay and manufacturers have found ways to stop the home repair and unauthorised repair markets such as by adding in device ID’s onto each hardware component and tying these to the main board so it stops working once you swap a part out.
This is a great move towards the goals of sustainability as devices will be able to be repaired more easily and the broken parts can be returned to Apple as stated in their announcement – “Following the repair, customers who return their used part for recycling will receive credit toward their purchase.”
Online forums and videos have made repairing devices easier as you can follow a set of instructions or watch someone else doing it. An example of a repair video Apple Broke iPhone 13 Screen Repairs.
The better part is that the parts can come with a manual to help you repair, which will provide an official way to do this.
It would be good to see other manufacturers allowing the ability to repair devices by providing spares.
So is it easier to repair a phone? It will be easier to obtain parts and instructions, however repairing a phone is still a challenge due to the many connectors and cables between the boards and components together. Care is needed if undertaking this as you may cause other damage during the process.
Opening my social feeds this morning for a quick browse over a cup of coffee and some toast, it doesn’t take long of scrolling down to find a post asking “What was the first car you owned? No Lying <laughing emoji>”. This post has 61k likes, 959k Comments and 8.4k shares and was only posted on 9th August. And people wonder why they get hacked.
Password systems for a long time have used a similar set of questions as they are usually easy to answer and remember, because they were life events. Questions such as:
What is your mother’s maiden name?
What is the name of your first pet?
What was your first car?
What elementary school did you attend?
What is the name of the town where you were born?
These types of social engineering data gathering posts are nothing new, but it would seem that people do not understand the greater risks around answering them.
With the large amount of data appearing on the dark web for usernames and a persons details (even if they don’t contain passwords) matching this data with the answers from social posts such as the one above gives a potential hacker more information about you. They now have the ability to reset your password using the answers you have provided to the security questions and take control of your accounts.
How many of you reading this post have answered the question similar to “What elementary school did you attend” or anything to do with education, but forgot that the same information is already lurking in your LinkedIn profile?
One way to check if your in any data on the dark web is to check using your email address at a service such as https://haveibeenpwned.com/
If you see a family member or friend post these types of questions on social media, it may be worth a conversation with them to advise of the dangers of such posts and the consequences of social engineering.
Tips to stay safe
Here are some tips for staying safe with your identity.
Don’t answer these types of posts on social media, even if its a friend who has posted it.
Check your not using an answer to a security question that is already in your social profile.
Use fictitious information instead of real information, but something you can remember.
Treat these answers like passwords and think about adding complexity to them.
Use two factor authentication where it is available on a system.
I am both excited and honoured at the opportunity to be part of the first cohort for the BCS F-TAG (Fellows Technical Advisory Group). Looking forward to participating and helping to lead bringing my experience and knowledge as part of this group.

Over the past year and a bit the world was forced online more that it was before and meetings in the most case became video calls. Some loved it and excelled, some we okay and some shy’d away from the camera completely for a number of reasons.
So not everyone wants to be in front of a camera and not everyone has a film studio set up and is broadcasting from their kitchen table – That’s okay. You use what you have to do the best that you can do. So what can you do to help yourself look better on the calls.
Most importantly is Be Yourself.
Relax. You are not presenting the news or interviewing a top senior official (Unless you actually are of course).
Be confident and have a positive mindset.
If you are camera shy, consider joining on camera to do the introductions, then turn the camera off.
Meetings will have a bigger impact when your on camera as your audience can see your reactions and expressions just as though you are in a face to face meeting.
Contribute to the call. Don’t forget to contribute to the call. That’s why your there.
Treat each call as a face to face meeting, it is but using video instead.
Reduce any distractions so you concentrate on the call in hand.
Try not to sit with a window directly behind you, especially with the sun shining as this produces a halo effect around you which does not look good to others on the call.
If you can’t move and don’t have blinds or curtains, then consider bring some light in front of you to counter balance the light behind you. You will need to do this even if you are using an in call backdrop.
Search for “led video light” on somewhere like Amazon for some good options. It doesn’t have to be expensive.
If you are using your phone to make calls, consider an “LED Selfie Light Stand”.
Knowing where your camera is on your device is important, it can make the difference between the audience looking up your nose and seeing your face at a good level.
Clean the lens. It can make a big difference, especially if you are using a phone.
If you are using a laptop and have an external keyboard and mouse, consider using a laptop stand to raise the camera or even an external camera on a stand to get a better shot.
If you are using a mobile, consider getting a stand for it if inside so you can keep the camera steady.
Also knowing where your microphone is on your device is and setting its sensitivity can ensure that you are heard okay and reduces any other background noises in your environment. Headsets with mics often have a mic set to only pick up the wearers voice only.
If you have an external mic, consider a windshield or pop shield to help reduce background noises.
This can mostly be controlled via your operating system device settings or for external mics and headsets the appropriate software/drivers may have options.
Remember your microphone has a mute option in the video calls.
Software in devices is very good at stopping feedback where you hear yourself speak on a call and the microphone is picking that up and replaying in over the top. Some people prefer to use an headset with inbuilt mic so they only hear the call in the environment you are in.
Most of the main video calling platforms now have the ability to place backgrounds behind you so the audience can’t see the area that you are calling from.
When using these it is important to remember that the software is using your camera to cut around your image and display the background behind you, so if you want to show something on camera, it may struggle and you may have to turn off your background to do this.
Test it out
Once you have a set up you are comfortable, test it out. There are options on most of the video calling platforms to do this, or set up a call with a colleague or friend to test out the set up and get some feedback.
Dr Lucy Rogers has produced a set of videos that were for her students, but would help anyone looking for some advice.
The last exam that I took was in an examination centre where you turn up and sit at an already configured computer. This time I sat the exam at home in my dining room with camera and microphones on. Special software ensuring that my only windows open are the exam and meeting room with the invigilator watching me.
Sitting down getting ready for the exam, I hit that unfortunate moment of your laptop is about to reboot and install an operating system upgrade. Great timing! Just enough time to get another device loaded with the right software and logins to the required pages. Not a good start to entering an exam for the mindset, but all went well in the end.
Study for this stage of the Data Fellowship has been part of the apprenticeship course and objectives. For me it was a cementing of the concepts and bringing some areas up to date.
Objectives are: Demonstrate knowledge and understanding of Data Analysis and its underlying architecture, principles, and techniques. Key areas are:
Explore the different types of data, including open and public data, administrative data, and research data
Understand the data lifecycle
Illustrate the differences between structured and unstructured data
Understand the importance of clearly defining customer requirements for data analysis
Understand the quality issues that can arise with data and how to avoid and/or resolve these
Explore the steps involved in carrying out routine data analysis tasks
Understand the range of data protection and legal issues
Explore the fundamentals of data structures
Explore the database system design, implementation, and maintenance
Understands the organisation’s data architecture
Understands the importance of the domain context for data analytics
There is nothing more annoying when your working on your computer and that popup appears saying “Reboot Now to complete the patch”. Thankfully some vendors have got wise to this over the years and have added changes to update at reboot/shutdown or allow to to choose a time. Annoying as it is, these patches are important and should not be ignored or delayed too long before applying.
When you think about patching/upgrading what do you think of?
The typical focus of home users is around the end device we use rather than the other parts of the homes IT infrastructure.
If you have your own router on the end of a connection, time to check when it was last updated. If its a managed device you can usually log in to it and check the last patch applied date. Is it being updated?
A recent discovery of FragAttacks (attacks that exploit security vulnerabilities that affect Wi-Fi devices) have shown that it is possible to steal data from any WiFi network that’s not patched, however its not an easy attack to recreate and vendors have been issuing patches to protect against this. This highlights the need for patching and updates to not just your end user device, but network devices as well.
As per a previous blog post – Good practices to adopt are
Check the manufactures website for firmware or driver updates on a regular basis – All devices within the home
If the device software allows a check to be made for updates on a regular basis make use of the tool
Use strong passwords
Change any default passwords
Don’t use the same password on different systems
Use passwords on your video calls
Use a VPN if working from home
Turn on two factor authentication on applications that allow it
Use Anti-virus and malware apps
If this is all second nature to you that’s great, however it may not be to others. Reach out to your family and friends and talk them through what they need to do so it becomes second nature to them.
Across the modern developed world, there are draws of old mobile devices in peoples houses and offices that are no longer used or in fashion. In some cases they are very old devices and in others the pull of the latest model has drawn the user to the new version or the software has stopped working on the older version.
By 2024 Statsia states there will be around 17.72 billion mobile devices operating in the world. That’s a lot of devices!
I will hazard a guess here and say there will also be a very high figure around the amount that will be still sat in desk draws.
Before I get onto upcycling I need to cover two areas – Recycling and Keeping up with the Neighbours
With the many recycling programs that vendors are putting in place the number of mobiles left outside of these programs is high. Mainly due to age of the mobile and damage to the device which makes it not worth anything for a person to send their phones in (main damage being to the screen). Yes I have a couple of these from family members that I need to get recycled.
There should be a bigger push to get these devices recycled to help reduce the impact on the earth and increase our sustainability. The main rewards for recycling a phone are for those that are mainly intact and hold some resale value. Once a phone has been dropped and damaged, to some its a thing that no longer holds value and therefore ends in the draw or hopefully not the bin.
There are some things that need to happen for users to help adopt this strategy:
Greater publicity around the value of the old phones
Guaranteed security of the destruction of data on the phone
Giving the user something back for recycling
Keeping up with the Neighbours
With new phones/models being produced each year how often do you hear things like:
“Oh the latest XYZ phone is out – I must get that!”
“Well I have a bit of damage on this phone so Ill get a new one as its coming out”
“We will no longer support that operating system version past dd/mm/yyyy”
“The cost of repair is quite high, its more economical to get a new one”
Reusing my old mobile devices as part of my home automation system to provide a number of screens and control points around the house appeals to me as I’m sure it would for lots of other people.
Rather than phasing out devices with operating systems that no longer work, having an option to reuse the device with a different operating system (changed) so it can operate as part of a home automation system would have massive appeal to the market and help drive the sustainability agenda. Okay, reduce the functionality of the phone to help secure it, but lets keep these devices useful with some code.
Okay so my screen may have a crack in it, but a screen protector over that and put into a cradle on the wall suits me fine.
So whats next? Dig out my old device, put some power in it and see what I can do with Home Automation.
Our brain is an amazing organ of that learns, remembers, controls, moves, repairs a complex body. It is in control of lots of functions and as part of that it is also responsible for our Logical and Creative Thinking. There are lots of articles that talk about the left side of the brain being responsible for Logical and the right side for Creativity. This was first researched by Roger Wolcott Sperry with his work on the split brain.
Either way the brain is still an amazing thing and you can learn to use both Logical and Creative Thinking techniques, you just need to apply a growth mindset.
“We cannot solve our problems with the same thinking we used when we created them.” – Albert Einstein
Logical thinking helps us to make “sense” of things, coming up with solutions and in decision making.
The five W’s and 1 H are commonly used as questioning to help form logical thinking. These are
Some add another H – How Much to the list as cost can play an important factor in decisions.
Creative thinking helps us approach things with an out of the box approach and an ability to look at things through different lenses to discover new solutions.
Taking a balanced view across Logical and Creative thinking, the Six Thinking Hats written by Dr. Edward de Bono starts to provide a balanced view by using the idea of parallel thinking to plan and use thinking more effectively. This can include logical and creative thinking.
Blue Hat – Process
White Hat – Facts
Red Hat – Feelings
Green Hat – Creativity
Yellow Hat – Benefits
brightness and optimism
Black Hat – Cautions
Build on the Skills
Learn different ways of thinking
Learn some new ways of thinking that you have not used before.
Practice and mix it up
As the phrase goes “Practice makes perfect”. Using different methods of thinking can bring different views and possibly different solutions to the problem/challenge.
There is nothing better than working with others to bring in different views and ways of thinking that you may not have thought of previously. This is a great way of seeing how other people approach the problem/challenge and help identify if there are areas you can improve/learn on.
Spend some time on creative hobbies that will help you build you creative thinking.
Learning a new skill
Learning a new skill will help you develop your thinking.
We have all at sometime done some sort of experiment, from maybe from a young age as to see which cry and actions resulted in the reward of milk to test driving cars to find which is best suited to your needs before you buy it. These are experiments that produced results from things we have tried and may not have thought about it as developing an Experimental Mindset. In this article I am concentrating on how this applies to data.
Here are my notes from my research into the topic.
Having an Experimental Mindset is one of the key traits in being a Data Analyst or Data Scientist and it is not a new term. This has been around as long as the field of science and research has. These arena have developed methodologies that have been adopted and taken forward by many other areas such as business and computing that can be used for testing and evaluating.
Overlaid with the areas for data this can be shown as:
Observations (Learning) –> Hypothesis (Testing) –> Scientific Law (Evaluating)
Observations (Data) –> Hypothesis (Product/Service) –> Scientific Law (Predictive Model)
Using this methodology, one of the more common types of Hypothesis Testing is A/B Testing. This sets out a framework for a simple controlled experiment against two versions (A and B) to look at the impact of changes to a thing or product. Some useful articles on A/B Testing are listed below that go into the details of it:
