Greg Wilson has noticed that lots of folks are using dodgy metrics to figure out if AI tools are worth their costs. Would you measure lines of code generated, or tickets closed? Or would you send out a survey asking whether developers feel more productive? Each of those approaches is flawed in a dif...
How OmniNode uses Redpanda to scale AI agent workflows
OmniNode’s founder shares his journey building the AI agent workflows that became OmniNode, and how Redpanda keeps topic names from drifting with contracts.
Real-time streaming for the agentic era with NVIDIA
NVIDIA Vera launches today with Redpanda as part of the ecosystem, delivering 5.5x lower latencies for agents running in mission-critical environments.
Beyond code generation: rethinking engineering productivity in the age of AI agents
How Dropbox is moving from AI tools that assist engineers to agentic systems that can execute scoped tasks, and how we’re building platforms to support those workflows.
Slack AI: The Path to Multi-Cloud
In early 2023, Slack faced a foundational challenge: serving Large Language Models (LLMs) at enterprise scale with the security, reliability, and performance our customers expect. Over three years, we evolved from basic infrastructure to orchestrating a sophisticated multi-cloud architecture. We did...
Official Discord Integrations for Steal a Brainrot, Grow a Garden, Brookhaven RP, and more
How some of the most popular Roblox games have integrated Discord account linking to enhance social features and safety capabilities for official community servers.
Solo founding is at an all-time high: Top performers have these traits in common
In 2025, solo founders in the top decile generated 61 times the revenue of the median solo founder in their first six months. We analyzed the data to understand what drives that gap.

At the GOTO Conference in Copenhagen in 2025, Kent Beck and I spent some time on stage talking and answering questions from the audience - a format I refer to as “two old geezers on a park bench”. We talk about our experiences with LLM-augmented programming (at that point - October 2025), we show ou...
The test suite as a regression sensor
Birgitta Böckeler finishes her post on sensors for coding agents by examining the role of a test suite as a regression sensor, focusing on the role mutation testing can play. more…
The VibeSec Reckoning
Vibe coding has significantly accelerated software prototyping but AI agents frequently recommend insecure configurations, creating security problems. Gautam Koul, Lucian Moss, Neil Drew-Lopez, and Daberechi Ruth Edeokoh share their experience while building applications for Thoughtworks's global ma...
Redpanda SQL is GA: the query engine that skips the pipeline
Your warehouse can't query data that hasn't been ingested yet. Redpanda SQL can. Ad hoc SQL against live topics and Iceberg history, no ETL pipeline required.
Introducing Nova, our internal platform for coding agents
Nova lets engineers run multiple coding sessions in parallel and lets internal systems use AI agents as part of automated workflows.
Bliki: Vibe Coding
Vibe coding is building a software application by prompting an LLM, telling it what to build, trying it out, prompting for changes - but without looking at any of the code that the LLM generates. This technique can be used by people without any knowledge of programming. However the resulting softwar...
Making It Easier Than Ever to Connect with Friends in League & VAL!
Link your Discord and Riot accounts to sync your friends lists, show your in-game activity as your Discord status, and invite your Discord friends directly to your League or VAL lobby.
Three more static code analysis sensors
Birgitta Böckeler adds discussion of three more sensors for static code analysis, focusing on checking and enforcing better modularity. Computational sensors for dependency checks were good at enforcing rules, but the rules were limited. Building a computational sensor for coupling data proved lackl...
Maintainability sensors for coding agents
In her recent article about harness engineering for coding agent users, Birgitta Böckeler laid out a mental model for expanding a coding agent harness: a system of guides and sensors that increase the probability of good agent outputs and enable self-correction before issues reach human eyes. Birgit...
Cloud Topics: Level Zero garbage collection
How Redpanda Cloud Topics tracks the lifecycle of temporary L0 objects and determines when they're safe to delete, without risking data loss or runaway storage costs. Read more.
Every Voice and Video Call on Discord Is Now End-to-End Encrypted
As of March 2026, E2EE is now enforced for every voice and video call on Discord. This represents a multi-year commitment, and Discord’s VP of Engineering is here to talk about why it matters.

Last week I spent a day at The Orchard Retreat, hosted by Mechanical Orchard. that brought together several people working in software development to talk about the profession’s future with the rise of agentic programming. The event was help under the Chatham House Rule, so I can’t attribute the com...
From latency to instant: Modernizing GitHub Issues navigation performance
How the GitHub Issues team used client-side caching, smart prefetching, and service workers to make navigation feel instant. The post From latency to instant: Modernizing GitHub Issues navigation performance appeared first on The GitHub Blog .
Bliki: Interrogatory LLM
When we need an LLM to perform a complex task, we often need to feed it a lot of context. Coming up with a design for a new feature requires descriptions of how we want the feature to appear to the user, guidelines on how it should be implemented, information on external systems to consult, and so o...
Egress problems and where to find them
Reducing the size and frequency of requests to your database has the double benefit of making your applications faster and cheaper.
Celebrate Discord’s 11th Birthday with an Exclusive Set of Emoji and Wallpapers
Discord is turning 11 this year! To celebrate, we made over twenty Discord-themed emojis, along with over twenty wallpapers, and even a digital poster for everyone to download, for free!
What is Code
Increasingly humans delegate writing code to agents. Will there even be source code in the future? To wrestle with this question, we have to understand what code is. Unmesh Joshi sees code as having two distinct but intertwined purposes: instructions to a machine and a conceptual model of the proble...
