Documentation and language reference is available at wkz.github.io/ply. A light-weight dynamic tracer for Linux that leverages the kernel's BPF VM in concert with kprobes and tracepoints to attach probes to arbitrary points in the kernel. Most tracers that generate BPF bytecode are based on the LLVM based BCC toolchain. ply on the other hand has no required external dependencies except for libc. I
Edit on November 2018: please have a look at our new article on emoji search because Elastic 6.4 now has a better support for Emoji! Edit on December 2016: there is now an Elasticsearch plugin for that! Since 2011 and Unicode 6.0, emoji is an integral and standardized part of the computer environment. They are more and more available on users keyboards (thanks to Android and iPhone) and as web dev

Built In No 3rd party kernel module required. These tools get their superpowers from BPF: an in-kernel virtual machine that can run tracing programs safely and efficiently (JIT & in-kernel aggregations). BPF is built into the Linux kernel, and bcc uses features added in the 4.x series. Powerful Observe the execution of any software. These tools use static and dynamic tracing of both user- and kern

GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools. Ask for what you need, get exactly thatSend a GraphQL q
Description A tool for understanding the behaviour of the Java HotSpot Just-In-Time (JIT) compiler during the execution of your program. Works by processing the hotspot.log file output by the JVM. This tool started out as a learning vehicle to gain a better understanding of HotSpot and JavaFX. I hope you find it useful :) Why would I use JITWatch? To verify whether methods you believe to be perfor

As Rene wrote on the ProxySQL blog yesterday: Although MySQL Query Cache was meant to improve performance, it has serious scalability issues and it can easily become a severe bottleneck. This is indeed something we have observed in the MySQL team for a while. Before we get to the subject of today’s post, let me start with an introduction. Introduction to Query Cache The MySQL query cache is a quer
RFC 8949 Concise Binary Object Representation “The Concise Binary Object Representation (CBOR) is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation.” JSON data model CBOR is based on the wildly successful JSON data model: numbers, strings, arrays, maps (called objects in JSON)
