VE Day 75 – May 2020

8 May Victory in Europe Day

VE Day 75 logoThis day celebrates the formal acceptance, by the World War II Allies,  of Nazi Germany’s unconditional surrender of its armed forces in, 1945.

2020 marks the 75th year since this historic agreement was reached, ending years of battle of an unprecedented  scale. However, it was a further three months before fighting ceased in Japan.

There are many fewer people these days with personal memories of the conflict and the final resolution. These special days help us remember the sacrifices made by so many on behalf of the countries for which they fought. Hopefully we learn from the problems of the past and use it to guide us to a peaceful future.

Today VE Day 2020 – 75 Years

Today, of course, we have a different solider, the care worker, battling a different kind of enemy. So please make your celebrations of VE day known, but do so safely #StayHomeSaveLives. In memory of all those who, fought and died 3SL salutes you.

Earth Day 2020

An Earth Day Like No Other

Based on 3SL logo and Photo by ATC Comm Photo from PexelsIt’s 50 years since the launch of Earth Day, and now nearly 200 countries coordinate a celebration of our fabulous home, with an important message that we need to look after it.

We may be the current custodians of this planet, but we share it with many. To them and ourselves, we have a duty of care. This year more than ever has demonstrated our own fragility. It’s demonstrated how we’re maybe not as invincible as we like to believe. Nature can be a strange beast. Whilst we may not be able to control nature, we can do our bit to care for what we have and ensure we don’t damage it.

As designers,  manufacturers and producers we need to consider how and whether what we engineer is beneficial and as non damaging to the environment as possible.

Whether you decide to; pick up that bit of litter on your exercise walk; choose a lower carbon or no meat meal; print double sided paper; leave the light off and the curtains open longer we can all make a difference. If the project you are working on uses resources, make sure you build environment requirements into your design. Make sure they assess and where possible lower the impact of the solution you choose.

On Friday 20th March, the World Health Organization (WHO) announced a large global trial, called SOLIDARITY, to find out whether any [of these drugs] can treat infections of the new coronavirus.. It’s an unprecedented effort—an all-out, coordinated push to collect robust scientific data rapidly during a pandemic.

Covid-19 Good News

We are all feeling the pressure, stress and anxiety as the current pandemic sweeps the world. We at 3SL believe that we need to pull together and focus on the positives. This Blog post is to present you with uplifting stories, helpful advice and Covid-19 good news about progress being made in stemming the rise of infections and finding medications to help tackle this virus.

Please note all stories and science shown below have been fact checked to the best of our ability and with all scientific claims, please be aware that these are very early days and information is prone to change. With that in mind…

Can we trust the data?

Barely a day goes by in the lifecycle of the coronavirus pandemic without a new model or analytical tool aiming to chart the spread or predict the outcome. But data for COVID-19 is far from perfect.

Comparing HydroxyChloroquine Trials

One minor side effect of the pandemic is that perhaps more people will learn about what drug research and clinical trials can really be like. Today’s example: we have a clinical trial of hydroxychloroquine from Wuhan that has just published on a preprint server. What’s good is that this one is blinded, randomized, and controlled (like the earlier hydroxychloroquine which one I blogged about here) from Zhejiang University, so we can actually talk about it rather than just spend all our time wondering what the heck is going on.

Tutor Font – Lip-Flaoor

A Tutor’s New Best Friend

Lip-Flaoor keyboard font
Tutor using Lip-Flaoor on Keyboard

Whilst during lock-down,  it is not the most opportune time to be thinking about face to face training, we were interested to spot this little training aid. It should make classrooms and training seminars a lot easier for the tutor and teacher.


Cradle on a computer based on unsplash.com image

When a teacher or tutor approaches a student, they are often faced with their keyboard and screen upside down. This makes it very difficult to type and aid the student. However, with the release of the new open-source font Lip-Flaoor, the tutor is  able to use the keyboard as if it is the right way round and the right characters will appear to the student. It is available from most good font factories.


  • ✅The font face looks very like Arial on the screen, so if perfectly readable.
  • ✅The student does not have to type any differently as they do not hold the <ctrl> key, so their experience is no different.
  • ✅If the tutor can type well, the dual mapping works wonderfully, they say it is like using any standard QWERY layout the right way up.
  • ❌The tutor, if not a competent typist may struggle as their fingers may not hit the “right” keys
  • ❌The need to hold the <ctrl> key while typing to enable the switch can be a bit awkward.

National Pencil Day

National Pencil Day March 30th

The humble mark of a human. We’ve moved a long way from chipping runes in stones, scratching Roman wax tablets, one significant find was that of a special form of carbon. Borrowdale is well known for its beautiful scenery and scrummy tea bread especially served with cheese. However, in around 1565 a ‘lead like’ substance was discovered that could be used to make a clean defined mark. This was ultimately the birth of the pencil, and an industry in Keswick. If you visit there really is a museum for all things pencil.

Random Pencils
Surprising how many pencils are in my desk tidy

Pencil day seeks to reconnect us with the humble pencil. The tool used by artists, designers and writers for hundreds of years. Why not take a picture of the chewed, blunt, or exquisite drawing tools and post them (#PencilDay).

Whilst we would definitely advocate Cradle as a preferred design tool, allowing cross references and traceability, not something you get on paper**. The humble sketch is still a goto design tool. And we should remember that.

Manual ‘ V’ Cradle

Take a 5 minute coffee break; Sketch what your product does or your company makes, with a pencil and paper and then post it! (#PencilDay).

We found some handy suggestions of other ways to celebrate here at pens.com.  Go on, celebrate pencil day and sketch away!

**Updating manual cross references between your sketches and text is possible with pencil and eraser, but easier if the database looks after it!
