Today, we’re tackling a common conundrum: chargers. Why so many different ones? And is the UK finally moving towards a universal solution, or will things stay tangled? Let’s dive into the ongoing debate over USB-C.
Why USB-C?
USB-C wasn’t always the go-to. We’ve seen everything from mini-USBs to proprietary cables like Apple’s Lightning. But USB-C arrived with a vision: one cable to charge everything. This port is versatile, offering faster charging, quicker data transfers, and a reversible design—no more fiddling in the dark to get it right! But, not all USB-C ports offer the same capabilities. For instance, a MacBook’s USB-C might support Thunderbolt technology, allowing super-fast data speeds and even external graphics card support. Your budget smartphone’s USB-C? It may only offer basic functionality. So, while the USB-C port might be universal, what it can do varies widely.
Is the UK on board?
With the EU already mandating USB-C, the UK is considering doing the same. If adopted, the standard could mean fewer chargers and less clutter. But in reality, companies are already making the switch due to global trends. Apple, for example, has dropped its proprietary Lightning cable for USB-C with the iPhone 15. So, UK regulations may not be a game-changer here.
The environmental impact
One key argument for a USB-C standard is cutting down e-waste. It’s estimated that there are 600 million unused cables lying around in the UK! A universal standard could reduce this number by lessening the need for multiple chargers. However, as people toss older cables, we might see an initial spike in e-waste.
The innovation dilemma
Standardisation could also slow innovation. Imagine if we’d settled on a single charger a decade ago—would USB-C even exist? There’s a risk that locking into one standard could stifle manufacturers from developing new technologies.
So, will USB-C rule them all?
It seems likely that USB-C will be the global standard for now, whether the UK enforces it or not. While it simplifies things, USB-C doesn’t solve every issue—charging speeds and capabilities still vary. So, don’t throw out those old chargers just yet. They might still come in handy!

Task management update
Have you seen the new interface for managing Tasks yet? We have significantly increased the data visibility and added a status to make it much easier to see the task workflow.
The full release notes for this update detailing everything that is new can be found here: News – Smart Revise
What’s next – have your say
The next major feature will be “Goals”, where Smart Revise uses the data about the progress a student is making to suggest how they should use the platform to achieve their flight path target cone and aspirational target. In addition to what’s on our road map there are other features that we develop in tandem based on your feedback too.
Currently we are finishing work on an option to automatically release marks immediately after AI has marked questions in a task.
Beyond that, here are the top 4 requested features at the moment:
FEATURE 1: Delete and add question option in addition to view and change when questions are chosen for a task.
FEATURE 2: Priority levers to influence the automatic question selection for a task. E.g. prioritise AI markable questions, or questions that have not been set before etc.
FEATURE 3: Tasks that only contain Quiz or self-assessed questions to have an option to present the marking for the question before the next question is shown. Known as the Q-A-Q-A approach in addition to the current Q-Q-A-A approach.
FEATURE 4: Question selector for Advance similar to the deck builder for Tasks.
If you have a preference which you would like us to work on next, please email us: admin@craigndave.co.uk.
Your vote will decide our priorities.
Classroom resources
New terminology guides coming soon
Our terminology guides for AQA, Edexcel and OCR courses that are included with a Craig’n’Dave membership were created some time ago and were based on definitions from the British Computer Society. When we introduced Terms mode in Smart Revise, we refined the definitions included in the platform to make them shorter and better match the requirements of the specifications and mark schemes. This means there is a difference between the older terminology documents and Smart Revise Terms. Nothing is inaccurate, it’s just different, and that’s not helpful!
To resolve this, we have created a new set of reports in the back-end of Smart Revise. This means we can more easily publish one set of key terminology documents that are the same in both the classroom resources and Smart Revise Terms.
We are currently redesigning our website, and when this work is complete, Craig’n’Dave members will be able to download the new terminology documents.
Time2Code
Christmas coding challenges
Our friends Anna & Harry at Mission Encodeable have once again made their Python Christmas coding challenges available for students and teachers. There are nine levels that exactly match the nine levels in Time2Code. This means that students can undertake some more festive themed challenges within the levels they are currently working on while still making progress.
The link to the activities is on the homepage of the Time2Code website.
Episode 52 will be the last video in the current Lesson Hacker series. Each week for a whole year, David Morgan aka “The Lesson Hacker” has produced a 5-minute video on our YouTube channel covering a topical issue in Computing. These also included questions in the video description that you could use for class discussions.
However, all good things must come to an end, but fear not, David is still going to be producing content for us, just with a different style and emphasis.
Next month will see the introduction of our new “shorts”. These new videos will be reduced to just one minute and focus on a core nugget of knowledge with a single question such as:
How do websites remember you?
Would increasing the size of the registers make your processor faster?
What makes a good program?
Why can your computer beat you at chess?
What Makes a supercomputer super?
Craig and OG Dave will also be producing some of these new videos too.
AQA A Level Remastered
SLRs 1 through 5 of our newly remastered AQA A level videos are now available on YouTube.
These videos have a better presentation style, better illustrations, better notes for students and much better audio! We advise you to bookmark the static links, so that your students always have access to the latest video instead of using YouTube directly: AQA A Level (7516-7517) Videos – Craig ‘n’ Dave knowledge video index
Craig’n’Dave members can also download all 187 PowerPoints we used to create the videos, even those that haven’t been published on YouTube yet.
Newsletter in video format
Every month, we also record an extended video version of this newsletter and upload it to YouTube – ideal listening for your commute: Craig ‘n’ Dave Unscripted – all episodes
Time 2 Code: A revolution in coding education for schools
26 November 2024
In an increasingly digital world, coding is fast becoming a must-have skill. But how do we make learning to code accessible for all students, no matter their level of ability? Time 2 Code, an innovative program created by Craig’n’Dave, offers a game-changing approach that empowers students to learn coding at their own pace, making the process not only effective but enjoyable.
What is Time 2 Code?
Time 2 Code is designed to meet the needs of students at different skill levels. Whether a student is completely new to programming or has some experience, this programme ensures that learning is both structured and flexible. It builds upon the UK National Curriculum, with a clear focus on progression through Key Stage 3 and 4 coding concepts like loops, arrays, and functions.
One of the standout features is its interdependent learning model. Instead of teachers standing at the front of the class and walking everyone through the same lesson, students can work through video tutorials, practical coding exercises, and assessments independently. This way, faster learners aren’t held back, while those needing extra help can get the individual support they need.
A flexible, student-centred approach
Time 2 Code follows a carefully designed structure, with students moving through different levels, from basic concepts like sequences and iterations to more advanced techniques involving arrays, strings, and file handling. By focusing on independent learning, it allows students to master topics at their own pace, ensuring no gaps in their understanding as they progress.
What sets Time 2 Code apart is its practical and engaging content. The programme combines video demonstrations with coding exercises that allow students to explore programming in a way that is both interactive and challenging. As students move forward, they are assessed on their ability to apply the skills they’ve learned, ensuring deep comprehension of the material.
Why Time 2 Code works
Research shows that students learn best when they are actively engaged in the material, and Time 2 Code’s approach ensures exactly that. It blends self-directed learning with structured assessments, making sure that students have the autonomy to learn but still receive the guidance they need at critical points.
The result? More confident, capable coders who are not only prepared for their GCSEs but for the future workplace as well. We love it over here at Craig’n’Dave, and we are sure you will too.
Get Time 2 Code – It’s FREE
Time 2 Code offers a rich, flexible way to teach coding that can benefit every student, regardless of their starting point. If you’re a teacher looking for a fresh, effective way to engage your students in coding, visit theCraig’n’Dave website to try out Time 2 Code for free today.
This is a topic that sparks a lot of debate: technology in sport. Some fans say tech is ruining their beloved sports, while others believe it’s making it fairer and more exciting. Let’s unpack how technology like Hawk-Eye, VAR, and AI have transformed the world of sports, for better or worse.
Precision or frustration?
Tennis fans are in for a big change. Wimbledon’s line judges are being replaced by Hawk-Eye technology—a camera system that makes precise calls on whether a ball is in or out. While this guarantees accuracy, something vital is lost: the drama. Remember when a player would challenge a call, and the crowd would hold its breath? Now, it’s simply “The computer says it’s out.” Accurate? Yes. Thrilling? Not so much.
Football’s introduction of VAR (Video Assistant Referee) was meant to correct bad calls. But has it made the game more enjoyable? While it does improve fairness, it’s hard to ignore the frustration when a game grinds to a halt for a five-minute review over whether someone’s toenail was offside. The precision is great, but the momentum of the game? That’s often the real casualty.
Data and AI: The future of fan engagement
Beyond refereeing tech, AI and data analytics are reshaping how fans engage with sport. Companies like Opta track everything from player speed to match predictions, turning sport into a data-driven experience. While it’s a different way of connecting with the game, some fans miss the messy, emotional moments that stats can’t capture.
So, Has tech really ruined sport?
Not quite. Technology hasn’t killed sport—it’s evolved it. The drama may now lie in data points and AI predictions instead of human error, but the heart of sport remains. Whether you’re shouting at a referee or a computer, the passion is still there.
Watch the full video on our channel to dive deeper into how tech is transforming sport.

What started as a non-profit dream has evolved into a tech giant worth a staggering $157 billion, raising questions about its original mission.
OpenAI’s humble beginnings
OpenAI – once a bold, altruistic initiative aiming to create artificial intelligence for the benefit of humanity – has undergone a dramatic shift.
Back in 2015, OpenAI set out with a noble goal: to make artificial intelligence accessible, safe, and beneficial for everyone. Spearheaded by influential figures like Elon Musk, it promised to use AI for the greater good, not just to line the pockets of the wealthy. Initially, a non-profit, OpenAI’s mission was simple: create AI that serves all of humanity, not just the elite.
However, the landscape changed quickly. By 2018, Elon Musk had left, citing concerns that the organisation was straying from its mission. Fast forward to today, and OpenAI’s once “open” nature seems a distant memory.
From non-profit to capped-profit
OpenAI’s transformation into a “capped-profit” organisation marked a significant departure from its non-profit roots. The company now walks a fine line between innovation and commercialisation, securing billions in funding from tech giants like Microsoft and Nvidia. While this has driven AI advancements, it’s also placed enormous pressure on OpenAI to monetise its technology, which risks sidelining its original vision.
Internal tensions and key exits
With the shift towards profit, OpenAI has faced growing internal conflicts. Safety researchers and AI developers, concerned that financial interests are outweighing ethical considerations, have begun to leave. Prominent figures, such as former CTO Mira Murati and Chief Scientist Ilya Sutskever, have stepped down, fuelling concerns about the company’s direction.
The critics speak out
One of the loudest critics has been none other than Elon Musk. From the sidelines, Musk has accused OpenAI of losing sight of its original purpose, claiming it’s now more focused on pleasing investors than safeguarding humanity from AI’s potential dangers.
OpenAI’s journey from non-profit idealism to a $157 billion behemoth leaves us wondering: has it lost sight of its mission, or is this just the price of progress? Let us know your thoughts in the comments!

We’ve all heard the scare stories: spend too much time on TikTok and suddenly you’re destined to fail your GCSEs and live in your mum’s basement forever. But is social media really as dangerous as some headlines make it out to be?
According to a new study by the World Health Organisation (WHO), there’s been a sharp rise in something called “problematic social media use” among teenagers. This doesn’t just mean spending hours on Instagram or YouTube; it’s when social media starts interfering with real life. We’re talking about skipping activities, arguing with parents about screen time, and feeling like you can’t stop even when you know you should.
The study surveyed nearly 280,000 teens across 44 countries and found that in 2022, 11% of them displayed problematic behaviours, up from 7% in 2018. Unsurprisingly, the pandemic played a major role in this spike, with many turning to social media during lockdowns. The situation is particularly notable in the UK, where teenagers are more prone to problematic use, especially among 13-year-old girls.
But before we start deleting our apps, the study also highlights that social media isn’t all bad.
For most teens, using social media helps them stay connected with friends and feel supported, especially during isolating times like the pandemic. Movements like #BlackLivesMatter and #FridaysForFuture are prime examples of how social media can create positive change on a global scale.
However, for the 11% struggling with problematic use, the situation can be different, with issues like anxiety, depression, and even withdrawal symptoms when they can’t check their phones. Boys, on the other hand, seem to be more prone to problematic gaming, with some spending over four hours a day on games like Fortnite and Minecraft.
So, is social media really that bad? The answer isn’t black and white. For the majority, it’s a useful tool for connection, but like anything, it needs to be used in moderation. The key is balance—managing screen time and not letting it interfere with mental health, studies, or relationships.

On the surface, the gaming industry appears to be thriving, with record-breaking profits and an ever-expanding player base. In 2023 alone, the industry pulled in a staggering $227 billion, a figure set to rise to $312 billion by 2027. But beneath this shiny exterior, cracks are starting to show. Why, despite these enormous profits, are we seeing widespread layoffs and studio closures, like Microsoft cutting 650 jobs after their $69 billion acquisition of Activision-Blizzard?
The boom-bust cycle of game development
One of the key reasons behind these layoffs lies in the industry’s notorious boom-bust cycle. Gaming companies often hire huge teams to complete major projects, but once the game is launched, developers are shown the door. Take the closures of Arkane Austin and Tango Gameworks—both produced critically acclaimed titles, but once the work was done, so were the jobs.
Corporate consolidation and layoffs
Another issue is the corporate consolidation sweeping the industry. Giants like Microsoft and Sony are snapping up smaller studios, only to announce job cuts shortly after. These layoffs are not random—they’re often a strategic move to impress shareholders, where ‘cutting costs’ is prioritised over the welfare of employees. It’s a trend that disproportionately affects younger and marginalised workers, who are often the first to go.
The rise of unions
However, hope is not lost. Game developers are starting to unionise, aiming to protect workers from these harsh realities. While unions can’t stop layoffs entirely, they can negotiate better severance packages, longer notice periods, and even job-sharing schemes to soften the blow.
An overcrowded job market
To make matters worse, universities are churning out new graduates eager to join the gaming world, but the industry simply doesn’t have enough jobs to go around. This leaves many talented individuals entering a workforce plagued by layoffs and limited opportunities.
What’s next?
So, where do we go from here? There’s growing pressure for gaming companies to create sustainable jobs, not just temporary contracts tied to individual projects. Players can also help by demanding better working conditions for developers. After all, shouldn’t the people behind our favourite games be treated as more than just disposable assets?

Can AI create recipes? How artificial intelligence is shaping the culinary world
26 September 2024
The rise of AI in the kitchen: Can robots create recipes that taste good?
Have you ever wondered what it would be like if artificial intelligence designed your pizza? From AI-generated recipes in top restaurants to major retailers using AI to predict food trends, technology is changing the culinary world. But the question remains: can AI really cook up something delicious, or is this a recipe for disaster?
The role of AI in culinary innovation
Artificial intelligence, particularly tools like ChatGPT, is making waves in the food industry. Restaurants are now using AI to analyse thousands of recipes and suggest creative flavour combinations that might not occur to human chefs. One standout example is Dodo Pizza in Dubai, where head chef Spartac challenged AI to create a pizza representing Dubai’s cultural diversity. The result? A surprising combination of shawarma chicken, grilled paneer, za’atar, and tahini sauce—an instant hit! This AI-designed pizza is still on the menu today and has become a customer favourite.
AI wins and fails in recipe creation
But AI doesn’t always nail it. While Dodo Pizza found success with their multicultural creation, they also experienced some AI-generated disasters, like a pizza with strawberries and pasta, or even worse, one with blueberries and breakfast cereal. Similarly, in the US, Velvet Taco in Dallas asked AI to help design a taco of the week. Among AI’s quirky suggestions, one recipe—prawn and steak tacos—was a massive success, selling 22,000 in just one week! Venicia Willis, Velvet Taco’s Culinary Director, is clear that while AI can boost creativity in recipe creation, it cannot replace the human element. Food, after all, requires human intuition to ensure ingredients come together harmoniously.
AI’s impact beyond the kitchen: Predicting food trends
AI’s influence goes beyond just recipes. Retailers like Waitrose are using AI to spot rising food trends, such as the recent surge in popularity of Smash Burgers. By analysing social media patterns, Waitrose was able to introduce their own version of the trendy burger, staying ahead of the competition. This demonstrates AI’s ability to not only create but also capitalise on emerging culinary trends.
The human touch is still essential
While artificial intelligence is making a mark on the food industry, it’s clear that AI-generated recipes still need human oversight. Chefs like Julian De Feral, a cocktail creator in London, are sceptical, arguing that AI lacks the common sense and intuition required for culinary creativity. After all, AI simply pulls from data, often relying on existing recipes or food blogs, which raises ethical questions about originality.
In conclusion, AI’s role in the culinary world is evolving, bringing a mix of innovation and bizarre combinations. While AI can inspire fresh ideas, the human touch is still crucial to ensure the final dish is both delicious and marketable.Curious to see AI in action in the kitchen?
