“The Rust programming language has been able to run on bare-metal without the standard library for quite some while now. However, most Rust applications depend on the
std crate, and therefore still need a full operating system to run.
This is where the Rumprun unikernel platform comes into play. It allows you to build your POSIX applications into bootable single-purpose images. Because unikernels are tailored to run a single application, they come without the footprint of a full-featured operating system. This makes them a great tool for application virtualization. Supported platforms of Rumprun include not only Xen/EC2 and KVM, but you can also run your image on bare-metal hardware.
Rumprun is based on rump kernels, it reuses NetBSD’s libc and drivers as components to provide a POSIX-y interface – the interface which the Rust standard library is built upon.
For the last couple of days we have been working on Rumprun support for Rust – you can now deploy your Rust application as a Rumprun unikernel. With our toolchain set up, a single cargo command is all you need to turn your Rust application into a Rumprun unikernel image…”
“Natural Language Processing” is a field at the intersection of computer science, linguistics and artificial intelligence which aims to make the underlying structure of language available to computer programs for analysis and manipulation. It’s a vast and vibrant field with a long history! New research and techniques are being developed constantly.
The aim of this chapter is to introduce a few simple concepts and techniques from NLP—just the stuff that’ll help you do creative things quickly, and maybe open the door for you to understand more sophisticated NLP concepts that you might encounter elsewhere.
The most commonly known library for doing NLP in Python is NLTK. NLTK is a fantastic library, but it’s also a writhing behemoth: large and slippery and difficult to understand. TextBlob is a simpler, more humane interface to much of NLTK’s functionality: perfect for NLP beginners or poets that just want to get work done…
“The goal of this project is to collect, preserve, and present source code, design documents, and other materials concerning the original LISP I/1.5 system, and as many of its follow-ons as possible. LISP was one of the earliest high-level programming languages and introduced many ideas such as garbage collection, recursive functions, symbolic expressions, and dynamic type-checking; it is still in use. This is a project of the Computer History Museum‘s Software Preservation Group. The editor appreciates comments, suggestions, and donations of additional materials…”

Modern C++ is clean, safe, and fast. It continues to deliver better and simpler features than were previously available. How can we help most C++ programmers get the improved features by default, so that our code is better by upgrading to take full advantage of modern C++?
This talk continues from Bjarne Stroustrup’s Monday keynote to describe how the open C++ core guidelines project is the cornerstone of a broader effort to promote modern C++. Using the same cross-platform effort Stroustrup described, this talk shows how to enable programmers write production-quality C++ code that is, among other benefits, type-safe and memory-safe by default – free of most classes of type errors, bounds errors, and leak/dangling errors – and still exemplary, efficient, and fully modern C++.
Background reading: Bjarne Stroustrup’s 2005 “SELL” paper, “A rationale for semantically enhanced library languages,” is important background for this talk…”
“I’ve been wanting to add more scripting capabilities to NGINX for a long time. Scripting lets people do more in NGINX without having to write C modules, for example. Lua is a good tool in this area, but it’s not as widely known as some other languages.
This is another milestone in the development of NGINX open source software and NGINX Plus. I want to take the opportunity to explain what nginScript is, describe why it’s needed, share some examples, and talk about the future…”
“nginScript is the next stage of the evolution of NGINX’s capabilities. It’s currently at a very early stage of design and development, and we welcome feedback and suggestions to help shape the future direction of this feature…”
“Suppose you could design your dream job that you’ll be starting on Monday. It’s at your ideal company with your ideal job title and salary. All you have to do is tell them what you want to do at your job and you can have it. What does your job entail?…”
