At Cloudflare, we do everything we can to avoid interruption to our services. We frequently deploy new versions of the code that delivers the services, so we need to be able to restart the server processes to upgrade them without missing a beat. In particular, performing graceful restarts (also known as "zero downtime") for UDP servers has proven to be surprisingly difficult. We've previously written about graceful restarts in the context of TCP, which is much easier to handle. We didn't have a strong reason to deal with UDP until recently — when protocols like HTTP3/QUIC became critical. This blog post introduces udpgrm, a lightweight daemon that helps us to upgrade UDP servers without dropping a single packet. ...

In today's rapidly evolving cybersecurity landscape, data breaches are an ever-present threat to organizations of all sizes. The most critical assets of an organization often reside within its digital infrastructure, including sensitive data and secrets. Among these, credentials (such as API keys, access tokens, passwords, and SSH keys) are a top target for cybercriminals. If these credentials are leaked or exposed, attackers can gain unauthorized access to systems and potentially wreak havoc on the organization. ...

This is a guest blog post by Sam Cox. Sam is the Co-Founder & CTO of Tracebit. When we started building Tracebit – a B2B SaaS security product – one of my key early decisions was to pick a programming language. While many startups gravitate toward Python, TypeScript, Golang, or Rust, I went a different way: C#. I’ve blogged quite a bit about this decision before and I wanted to share a few highlights here. ...

Did you know? C# allows you to define custom operators for your own types by overloading built-in operators (like +, -, ==, etc.). This is not something most developers use often, and it can make your code behave like native types, which is a powerful but underutilized feature. Welcome to dotInsights by JetBrains! This newsletter is the home for recent .NET and software development related information. 🔗 Links Here’s the latest from the developer community. ...

In this post I explore the new .NET AI Chat Web App template (currently in preview) to create a chat application and take a brief look at everything it provides. In the next post I then customize the app so that instead of ingesting PDFs, it ingests the contents of a website and uses that data to answer questions in the chat. Getting started with the new .NET AI Chat Web App template The .NET AI Chat Web App is a new template that shows how to get started building a chat style application backed by a large language model (LLM). Chat apps are one of the most prolific use cases for AI (obviously heavily popularised by ChatGPT), and while they’re not always the best way to “add AI” to your app, they can have their uses. ...
