With LLMs becoming increasingly normalized in the industry, an overreliance on them can allow bugs to slip through the cracks.* *In this talk, I'll demonstrate a practical debugging workflow: Debug first. Prompt second. I'll show how browser DevTools reveal what's actually happening faster than any AI can guess.* *You'll learn:* * *Essential DevTools features that improve your bug-fixing prowess* * *When to reach for your browser and when AI can actually help* * *The almost forgotten art of breakpoints and strategic console messages* *AI in your codebase represents growth, but understanding your runtime state represents mastery. This talk is about balancing both and knowing which tool to reach for first.* ➡️ **Why Your Marketing Scripts and Cookie Banners Are Ruining Your Lighthouse Scores - [Christopher Burns](https://www.linkedin.com/in/burnedchris/)** *Most marketing scripts and cookie banners run on the critical path. They block the main thread, delay first paint, and inject third-party code before the page is interactive.* *Consent managers often make this worse by synchronously loading vendors, mutating the DOM repeatedly, and re-hydrating UI after page load. The result is slower LCP, higher TBT, and unstable CLS.* *The fix is not fewer scripts, it is better orchestration. Treat consent as infrastructure, load vendors after intent, and keep compliance off the critical path.* — **👍 Code of Conduct** By registering for this event you agree to comply with our [CoC](https://gitnation.com/coc) **📩 Contact** events@gitnation.org https://twitter.com/ReactAdvanced http://youtube.com/ReactConferences https://bsky.app/profile/reactadvanced.gitnation.org

## Details Welcome to the DevSecOps London Gathering February Event on Wednesday 19 Feb in collaboration with London DevOps! We bring you two amazing talks, as well as the usual conversations, pizza and beer! 📍 **Hosted at Autogen AI, Pentonville Road, London** 📅 **Wednesday, 19 February** 🕕 **6:00–8:00 PM** ## Talk 1 **Abstract:** Concrete CMS, a popular open-source content management system, contains a critical flaw in its file upload functionality that can be exploited in two distinct ways. This talk demonstrates how a single upload can lead to a Server-Side Request Forgery (SSRF), allowing access to internal cloud resources, and a double race condition that enables Remote Code Execution (RCE) via a malicious backdoor. We’ll walk through the exploitation process, show how existing protections can be bypassed, and highlight practical steps to secure file upload mechanisms in real-world applications. ## Talk 2 **Abstract** Treat authentication as a production-critical system with its own failure modes and operational risks. In this talk, I break down real-world auth incidents involving JWKS rotation errors, refresh token storms, clock drift, and session store outages. I show how to define SLIs and SLOs that measure user impact and how to build monitoring and alerting that expose real reliability problems. I demonstrate practical guardrails such as token caching, exponential backoff with jitter, circuit breakers, and feature-flagged degraded modes. Finally, I walk through an incident runbook that helps teams diagnose, mitigate, and recover from authentication failures safely and quickly.

A relaxed, four‑hour or so photo walk that starts at Bank Station, threads through the heart of the City, and lands you in Soho by 7:00 pm – perfect for capturing the post‑work buzz without feeling rushed. ## Overview * **Start:** 4:00 pm – Bank Station (Royal Exchange side) and areas nearby * **Midway:** 6:00 pm – Walk through St Pauls, City Thameslink, Fleet Street and then wander through Covent Garden * **Finish:** 8:30 pm – Central Soho (Carnaby Street / Berwick Street area) The route balances iconic landmarks, spontaneous street moments, and the gradual shift from daylight to evening neon, giving you a rich visual story in a single evening. This walk will be about 3 to 4 miles, so please bear this in mind. You may choose to do the first half or the second half instead of the full walk :) We will sign off the evening over drinks / food (for those able to stay back) ## Key Shooting Opportunities * **Office exodus:** Capture groups spilling onto the pavement, coffee in hand, with the City’s glass towers framing the scene. * **Market ambience:** Stalls and lanterns in Covent Garden add texture and warmth. * **Neon nightlife:** Soho’s iconic signage provides bold contrasts for low‑light portraits. ## Gear & Practical Tips * **I will provide one roll of KODAK XX 35mm film for you to use. Each roll has 36 exposures. You may choose to use it at your ISO of choice. I personally tend to stick with 800 ISO, using a slower aperture (5.6 to 11 ) in day light and faster aperture (1.5 to 2.0) in low light. However, this film can be shot at 250, 400, 800 and 1600 ISO easily** * Please make sure you can manually select the ISO on your camera, else this film roll will default to 100 ISO and unless you have an automatic flash, you will struggle with your camera * You can join us at any point of time in the walk . I will share our Live location on WhatsApp (will create a WhatsApp group 2 days before the walk, including the meeting point) Please note: The aim of the walk is to shoot at least one roll of Kodak XX, which will be provided to you. If you do not intend to use XX or not use a film camera kindly do not join this particular walk The cost of the walk includes the film roll and payment required upfront via PayPal to ensure commitment to the walk If you require a film camera for the walk please let me know in advance and I could get one for you to use for the evening

This meetup is a beginner-friendly, hands-on workshop focused on building shaders in Unity using Shader Graph. Instead of slides or theory-heavy lectures, we'll build real shaders together step-by-step. The format is structured but interactive. You'll watch a quick demo, then build each shader yourself with guidance. By the end, you'll have created multiple shaders you can immediately use in your own projects—and understand how to make more. **What to Expect:** * Build 4–5 complete shaders from scratch * Color tints, snow accumulation, scrolling water, dissolve effects, and more * No prior shader experience required * Checkpoint files provided if you fall behind * Resources for continued learning All experience levels are welcome. Whether you've never opened Shader Graph or just want to fill gaps in your knowledge, this is a supportive space to learn by doing. **Food and drinks provided. Join us to learn, build, and level up your shader skills.** I added the Unity project to the repo here - https://github.com/EricJRico/IntroToShaders.git This is what we'll be using for the session.

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation* Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

As you may or may not know--I didn't until late last year--Aristotle wrote extensively on "friendship" in the Nicomachean Ethics. After 69 years the concept of friendship still creates questions and uncertainty. I had close friends in high school and for a few years after high school but our interests diverged and people moved all over the country so it was hard to maintain connections. * So if I/you haven't talked with a friend for several years, are you still friends? Are we friends who meet at Drunken Philosophy or Omnipresent Atheists? * Can you be friends with someone with whom you have virulently divergent political views? Sartre and Camus could not. * Aristotle regarded friendship as essential to a good life, not merely an added "bonus." Do you agree? * In the Nicomachean Ethics (Books VIII and IX), he claims that wealth and power are meaningless without friends. Trump has wealth and power but seems to have no real friends, but wealth and power seem meaningful to him in perverted ways. Can you have meaning in your life without friends? * Do men and women view and maintain friendships in different ways? * Aristotle categorizes friendship into three types, based on what forms the bond: * **Utility**: Based on mutual benefit, but this type is fragile and ends when the usefulness ceases. * **Pleasure**: Based on shared enjoyment (e.g., humor, hobbies). Common among youth but fades as interests change. * **Virtue (The "Complete" Friendship)**: Based on mutual respect for each other's character and goodness. You wish good for the other for their sake, not yours. * **Key Principles of "True" (Virtuous) Friendship:** * **Permanence**: Virtuous friendships last a lifetime whereas those based on utility and pleasure are fleeting. * **Reciprocity**: Requires mutual goodwill; secret or unreciprocated affection does not qualify. * **The "Second Self"**: A true friend is "another self"—their virtue helps you understand and improve yourself. * **Time and Intimacy**: Deep ("complete") friendships are few, built on time and shared experiences. * **Self-Love and Friendship:** * Good friendship starts with being a friend to yourself. * They distinguish shallow egoism (chasing honors) from real self-love (pursuing virtue). * A virtuous person’s pleasant self-company allows them to be a stable, good friend to others. * Aristotle argues that one's social circle ultimately reflects one's character—a view with striking relevance today. Well--the Drunken Philosophy social circle certainly reflects good character!
