Fuzz testing is incredibly effective for mechanically discovering software defects, yet remains underused and neglected. Pick any program that must gracefully accept complex input, written in any language , which has not yet been been fuzzed, and fuzz testing usually reveals at least one bug. At least one program…
First: performance is tricky and bechmarking even more so. I will talk some numbers in this post but of course they are what I have measured for my specific tests on my machine. Your numbers for your test cases will be different. Over the last six months or so, curl has undergone a number of … Continue reading curl 8…
jQuery: The Write Less, Do More, JavaScript Library
Automating releases, semantic version bumps, and API calls often involves configuring branch permissions and storing long-lived credentials in pipeline variables. Managing credential rotation adds an ongoing maintenance burden. Today, we’re introducing granular step-level permissions and container tokens in Bitbucket…
We've all used a public transit router to find a quick route from A to B, such as Google Maps or CityMapper, but how do they actually work?
Run AI models locally in Ruby! 💻 Use Ollama to download & run open-source models like Mistral. Integrate them into your Ruby apps using HTTP requests. Great for data security & privacy.
We just open sourced "React Flow" : A library for rendering interactive node-based graphs with a smooth panning and zooming behaviour and…

Mill is a new build tool for Scala: it compiles your Scala code, packages it, runs it, and caches things to avoid doing unnecessary work. Mill aims to be better than Scala's venerable old SBT build tool , learning from it's mistakes and building upon ideas from functional programming to come up with a build tool that…
In this series, we will explore how to write a compiler for a small subset of C to LLVM in Haskell. Our language, Micro C, is basically a small subset of real C. We'll have basic numeric types, a real bool type, pointers, and structs. At the end of the series, we'll have a beautiful executable, mcc (Micro C…
Traditionally, software is produced in this way: write some code, maybe do some code review, run unit-tests, and then hope it is correct. Hard experience shows that it is very ...
LLVM has two new register allocators: Basic and Greedy. When LLVM 3.0 is released, the default optimizing register allocator will no longer be linear scan, but the new greedy register allocator.
Debugging with intelligence via probabilistic inference Xu et al., ICSE’18 Xu et al. have built a automated debugger that can take a single failing test execution, and with minimal interactio…

Recently Slack on the desktop has been going through an awkward adolescence. Instead of flailing limbs and pitch squeaks, ours has manifested in ways rather more grim: inexplicably failing to render content, reloading during common operations, and error screens that aren’t actionable. The only silver lining has been…
For more than two years, I've been using Tailwind CSS almost every working day for company projects and a lot of weekends for my side projects.
Today you are frustrated.
Learn programming languages like TypeScript, Python, JavaScript, SQL, and regular expressions. Interactive with real code examples.
GitHub secret scanning protects users by searching repositories for known types of secrets. By identifying and flagging these secrets, our scans help prevent data leaks and fraud. We have partnered…
