Rule 53: If you can think of it, someone's done it in the DNS DNS, like almost any protocol or system on the internet, has been used in ways almost from the day it was born that were probably never intended or envisioned by its inventors. This talk is an overview of some of the more interesting ways that people have thought to embrace and extend DNS, from large to small. From static traceroutes to

WebGPU is a new graphics and compute API designed from the ground up by a W3C community group. It's a successor to WebGL, which also has a chance to become a standard on native platforms. We are going to talk about the API itself as well as our Rust-based implementation "wgpu". Expected prior knowledge / intended audience: basic familiarity with one of the graphics APIs is good but not required. W
How to navigate the rich but confusing field of (Full) Text Search in PostgreSQL. A short introduction will explain the concepts involved, followed by a discussion of functions, operators, indexes and collation support in Postgres in relevance to searching for text. Examples of usage will be provided, along with some stats demonstrating the differences.
How is it possible that PostgreSQL used fsync incorrectly for 20 years, and what we'll do about it. About a year ago the PostgreSQL community discovered that fsync (on Linux and some BSD systems) may not work the way we always thought it is, with possibly disastrous consequences for data durability/consistency (which is something the PostgreSQL community really values). I'll walk you through fsync

The goal of this talk is to introduce programmers with C++ experience to tool building with LLVM. My expectation is people know C++, have heard of, but not used LLVM. Examples provided on the slides will be small but useful snippets, and it is the expectation you will be able to build the examples provided within a few hours.
The last pieces are finally falling into place. After years of design and implementation, 2015 will be the year that Perl 6 officially launches for production use. In this talk, the creator of Perl reflects on the history of the effort, how the team got some things right, and how it learned from its mistakes when it got them wrong. But mostly how a bunch of stubbornly fun-loving people outlasted t
We show general purpose GPU computing using Google's Go language together with minimal use of Nvidia CUDA. This unusual match can perform very reliable, high-performance scientific computation using surprisingly brief and clear code. GPU-accelerated scientific computing is gaining popularity because of its high performance. Often, nvidia's CUDA toolkit is used together with C/C++. Although undenia
FOSDEM is a free event for software developers to meet, share ideas and collaborate. Every year, thousands of developers of free and open source software from all over the world gather at the event in Brussels. No registration necessary. FOSDEM is over for another year! We would like to thank everyone for their contribution to another successful FOSDEM! Please tell us about your FOSDEM experience
