Dev Proxy is an API simulator that helps you effortlessly test your app beyond the happy path.
You test your app to make sure it works as intended. But what if the APIs you use fail? Will your app lose your customer's data? How do you test for this? Simulating API failures is hard. You end up writing code that you won't be shipping or worse: not testing at all. That's why we built Dev Proxy, to simulate API errors so that you can easily test your app without changing your code.
Create executable demo documents that show and prove an agent's work.

Your language isn’t broken, it’s doing floating point math. Computers can only natively store integers, so they need some way of representing decimal numbers. This representation is not perfectly accurate. This is why, more often than not, 0.1 + 0.2 != 0.3.

Using iframes in a responsive page can be frustrating. It’s easy enough to make an iframe’s width span 100% of its container, but sizing its height is tricky — especially if the content of the iframe changes height depending on page width (for example, because of text wrapping or media queries) or events within the iframe.

An embedded database built on object storage.
Unlike traditional LSM-tree storage engines, SlateDB writes data to object storage to provide bottomless storage capacity, high durability, and easy replication.
SlateDB is an embedded storage engine built as a log-structured merge-tree. Unlike traditional LSM-tree storage engines, SlateDB writes data to object storage (S3, GCS, ABS, MinIO, Tigris, and so on). Leveraging object storage allows SlateDB to provide bottomless storage capacity, high durability, and easy replication. The trade-off is that object storage has a higher latency and higher API cost than local disk.

This page describes rEFInd, my fork of the rEFIt boot manager for computers based on the Extensible Firmware Interface (EFI) and Unified EFI (UEFI). Like rEFIt, rEFInd is a boot manager, meaning that it presents a menu of options to the user when the computer first starts up, as shown below. rEFInd is not a boot loader, which is a program that loads an OS kernel and hands off control to it. Many popular boot managers, such as the Grand Unified Bootloader (GRUB), are also boot loaders, which can blur the distinction in many users' minds. All EFI-capable OSes include boot loaders, so this limitation isn't a problem.
High-level tracing language for Linux.
bpftrace is a high-level tracing language for Linux. bpftrace uses LLVM as a backend to compile scripts to eBPF-bytecode and makes use of libbpf and bcc for interacting with the Linux BPF subsystem, as well as existing Linux tracing capabilities: kernel dynamic tracing (kprobes), user-level dynamic tracing (uprobes), tracepoints, etc. The bpftrace language is inspired by awk, C, and predecessor tracers such as DTrace and SystemTap.
