That's the key insight of "context graphs" - giving agents access to why decisions are made improves their performance. This leads to \*Agentic World Models\*: the convergence point where agent memory, knowledge graphs, and context graphs meet. Agents discover written policies and unwritten tribal knowledge, learn formal org structures and informal influence networks, and capture the \*decision traces\* that explain not just what happened, but why it was the right call. We'll cover: \- how to capture decisions traces \- how to query the context graph when making decisions \- a demo of what this looks like Together, we'll put context in context.

\- Meet at 10:30 on the seats near the information desk in the Great Court\. \- Individual tuition with helpful step by step explanations\, demonstrations as you draw in the galleries\. \- Share your work with other students in the cafe are of the Great Court\, located nest to the Sainsbury Exhibitions Gallery\. The British Museum houses sculptures from many different cultures, many of which are from elaborate monuments. Some have powerful and moving static presence, and others a lively sense of movement. \- Understand the role statics and dynamics in the making of a drawing \- Practise techniques for aligning forms and sensing proportions \- Use a variety of lines and tones \- Respond to the flow of rhythm

These fortnightly sessions are dedicated to the discussion and exploration of an idea that I, as the organiser, have planned. No prior reading or knowledge is required. For more information, please visit https://www.think-philosophy.group/about/

**This is a ticketed event for £10, purchases available at [eventbrite here](https://www.eventbrite.co.uk/e/philosophies-of-east-west-first-evening-tickets-1982072570414?aff=oddtdtcreator&_gl=1%2A1ynpvct%2A_up%2AMQ..%2A_ga%2AOTQxMTAzNjU3LjE3Njk3ODM4NTk.%2A_ga_TQVES5V6SH%2AczE3Njk4NzEwNzckbzMkZzEkdDE3Njk4NzE5NTMkajQ5JGwwJGgw).** Philosophy means the love of wisdom, and being a philosopher essentially means having an active attitude and awareness towards life. We are all born philosophers, with a natural need to ask questions and with the intuition that there are answers to be found. Every civilisation has tried to pass on its wisdom, leaving us a vast heritage of useful knowledge and experiences to rediscover. Explore the timeless ideas that have inspired and guided humanity throughout history and their relevance and practical application for our lives. This first evening can be attended for £10 as a standalone introduction to **Philosophies of East & West** however if you are interested in learning more about the full 18-week course and applying, please visit [philosophiesofeastandwest.org](https://www.philosophiesofeastandwest.org/ "https://www.philosophiesofeastandwest.org/")

This is a studio based long pose life drawing and painting session. We have a nude model for two hours in a single pose to give you time to complete a finished drawing or to paint the figure.

This month we have a visiting speaker from think-cell, Sebastian Theophil, who will talk to us about error handling in C++26 (with sprinkles of C++23). We also have space for a shorter talk, or lightning talks. If you would like to speak - even for just five minutes, please drop something into cppldn.uk/speak. **think-cell** will also be supporting the group by providing pizza and drinks - thanks **think-cell**! Thanks, also, to **Maven Securities** for hosting us again, this month. **As usual we'll need your full name for the door list, so we'll be asking for this on registration** (as this may be different to your username). This data will only be used for the door list/ registration and not published anywhere or used for other purposes. If you'd like to speak at a future event please get in touch at [cppldn.uk/speak](http://cppldn.uk/speak). **Here's the approximate schedule:** **18:30** *Doors open* **19:00** "Intro and news" - *Phil Nash* **19:10** *"compile_assert - Compile time C++ assertions" - Jonathan Grant* I present compile_assert(expression, message), a new C++ keyword proposal for enforcing assertions at compile time within ordinary (non-constexpr) functions. compile_assert provides advanced asserts at compile time, not runtime. Used for bounds checking, parameter validation and data validation at compile time. All three major compilers (GCC, Clang, MSVC) are supported with a sample implementation. The example implementation does this by using GCC’s attribute error which works with Clang. **19:25** "Compile-Time Data Layout Transformation with C++26 Reflection" - *Arturs Kalnins* We’ll use C++26 static reflection and injection to convert an AoS into a SoA at compile time, live on the latest GCC, with zero macros and zero boilerplate. **19:40** *break* **20:00** "To Err is Human: Robust Error Handling in C++26" - *Sebastian Theophil* A walk through the new error handling features in C++26 — including \`std::expected\`, \`std::stacktrace\`, contracts, and more — and how they can help us write more robust, maintainable code. **21:00** *Conclusion, and moving on somewhere else* \-\-\- **About the speakers** *Sebastian* has been working at think-cell since it was founded in 2002. In the last few years, among many other things, he has ported think-cell to run on macOS. He also maintains the typescripten project, which lets programmers call JavaScript libraries from C++ code compiled to WebAssembly in a convenient and type-safe way. He enjoys leaving his desk from time to time to talk at international C++ conferences. *Jonathan* has been a Software Engineer since 2003, worked in the video games industry and also embedded space for a long time at Renesas in safety critical systems for the automotive sector in C and C++. He also develops bespoke machine learning software in C++. He has a BSc Computer Science and an MSc Software Engineering. *Arturs* is a C++ software engineer with a background in aerospace engineering, where he developed a strong foundation in mathematics and systems thinking. He builds reliable, high-performance systems across embedded software, networking, and distributed platforms, with a particular focus on modern C++ (23/26), Rust, and performance-critical design. He enjoys tackling complex engineering challenges, designing clean abstractions, and contributing to the standards and practices that help teams deliver robust systems effectively.

As any one who has ever taken a selfie, only to delete it and try for a better one knows, we all have an idea of how we want to be seen by others. This was always the case. When commissioning a portrait or painting a self portrait, the foremost thing in a sitter's mind was how to present a most flattering image, and how to persuade others of one's best qualities - skills, intelligence, goodness, power or status in society. The consequence of that is that portraits usually lie in favour of propaganda. We will look at the way artists from the Renaissance onwards manipulate their sitters' and their own likenesses to reflect their ambitions and society's expectations.

The Barbican Centre is a symbol of brutalist architecture. Sharp edges, concrete, light and shadow, columns and blocky shapes: it’s a place rife with opportunities for our keen eyes and blazing cameras! This maze of shapes and lines is where we will be continuing our journey towards street photography excellence. It isn't the place for complex, layered crowds. Instead, we will focus on a slower, more intentional pace—seeking out the shapes, lines, and patterns where we can purposefully place a human element to create a striking image. Open to all skill levels. Whether you shoot on a smartphone or a high-end camera, this workshop is about elevating your craft and learning to capture better, more intentional images. For those who have joined me before, I look forward to continuing our journey. We’ll be building directly on the skills you’ve already practiced, adding this new 'intentional' element to your toolkit to create even more compelling street scenes. I will be there helping you along to develop the frame and to understand how to build the image from the ground up. Join us for a great afternoon, sharing your passion with fellow photographers and taking an important step in your journey to mastering the streets with your camera! What will you need? A camera or a smartphone, of course, and a pair of comfortable shoes. And a determination to have a good time, because you certainly will! After the workshop you will be invited to join the Tap on the Shoulder WhatsApp group, where you will be able to share your best efforts from the workshop and receive feedback from me and your peers. At the end of the workshop we will be heading for the nearest pub for a refreshment and some banter, enjoying each other’s company and planning our future street photography mischief! What are you waiting for? Book your place now and take your next step in improving your street photography skills! Bring your children, they can participate as well! Attendance is free for children under 15 years of age: please use the discount code UNDER15. Please come 5-10 minutes early. I will wait for 5 minutes for late arrivals then start the workshop out of respect for the people that arrived on time!

Immerse yourself in the calm, creative world of botanical watercolour with **Ann Mackowski**— an **award-winning artist** whose work has been **featured on *Sky Landscape Artist of the Year*** and who **exhibits with the Royal Society of Painters in Watercolours**. In this relaxed and friendly workshop, Ann will guide you through the process of painting fresh leaves and delicate blooms, sharing the professional techniques she uses to capture the vibrancy and grace of the natural world. Whether you’re completely new to watercolour or looking to refine your skills, this is a wonderful way to unwind, connect with nature, and rediscover the joy of painting. Enjoy a few peaceful hours of creativity, conversation, and colour — and leave with a piece of art you’ll be proud to frame. **You will learn:** * How to sketch and paint plants with both **accuracy and flow** * **Colour mixing** secrets for lively greens, florals, and subtle natural shades * Techniques for **layering transparent washes** to create depth and softness * Adding **finishing touches** with fine detail brushes * How to **turn a simple study into a beautiful, frameable piece** We will take inspiration from a mix of fresh flowers, and reference works from famous botanical artists. After a step-by-step follow along exercise and several fun warmups in brushwork, you'll be able to complete your own unique composition. Midway through there will be a tea and refreshment break, and a chance to mingle with your fellow artists. A joyful celebration of colour, creativity, and the beauty of nature — perfect for anyone who loves to paint or simply wants to begin

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
