XLS is an open-source toolkit for building high-level hardware with a modern compiler stack that spans from a functional DSL to optimized IR and hardware generation. At the front end, DSLX lets you describe algorithms with strong typing and familiar control flow while remaining synthesis-friendly. The compiler lowers DSLX into a rich intermediate representation, applies aggressive optimization and scheduling passes, and can either JIT the design for software simulation or emit Verilog for FPGA/ASIC flows. A key idea is “software-style” iteration: fast, deterministic simulation via the JIT encourages test-driven development and property checking before committing to RTL. XLS also provides tooling for pipelining, state insertion, and formal equivalence checks between different stages, giving developers confidence as designs evolve. The result is a productive path from high-level specification to real hardware, without giving up control over latency, throughput, and area trade-offs.
Actions & Tags is a Zotero plugin for automating library organization through event-driven actions and custom scripts. It can add or remove tags when items are created, opened, closed, modified, or matched by other triggers. Users can also launch actions manually through configurable keyboard shortcuts. Built-in and community examples cover tag replacement, item-link copying, automatic note creation, and metadata translation. Scriptable operations allow advanced users to manipulate selected items, notes, collections, and application behavior. Actions can be combined into repeatable workflows that reduce manual cataloging and cleanup. The plugin is installed as an XPI extension and is intended to make Zotero adapt to individual research habits.
