Improve startup time by making the classes of an application instantly available, in a loaded and linked state, when the HotSpot Java Virtual Machine starts. Achieve this by monitoring the application during one run and storing the loaded and linked forms of all classes in a cache for use in subsequent runs. Lay a…

gcvis is a simple way of visualising the operation of the garbage collector within a Go process. Here is a screenshot of it in operation. The rest of this article explores how gcvis works and how to interpret its results.
My VLSI tools take a chip from conception through testing. Perhaps 500 lines of source code. Cadence, Mentor Graphics do the same, more or less. With how much source/object code?
I was really surprised to learn that Swift recently adopted Smalltalk keyword syntax: [Accepted] SE-0279: Multiple Trailing Closures . Tha...
Very roughly speaking, functional programming (“FP”) and object-oriented programming (“OOP”) have similar levels of expressive power and similar abilities to encapsulate programs into smaller parts that can be combined and recombined.
This is one of a series of posts on languages, you can read more about that here . A grab bag of observations on the Go programming language, positive and negative. It bucks some orthodoxy on what a good effective language is supposed to look like. It makes sensible engineering decisions and is sq
A report on the 1980 LISP conference at Stanford University, held the week after the AAAI Artificial Intelligence Conference. Written for Byte.
Safely refactoring Ruby traditionally involves many incremental steps and feature flags. Sorbet and 100% branch coverage make it possible to refactor a lot of code safely.
My coding time this year has been invested in Quamina , an event-filtering library implemented in Go. Just in the last couple of weeks I spotted an opportunity to bring Go’s shiny new generics to bear, and not just anywhere, but for a central data structure. I got good results, but the process was sort of painful; I…
An unfair heavily biased apples-to-oranges comparison… unless?
This is the fifth post in my planned multipart series on memory management. You will probably want to go back and read Part I , which covers C, parts II and III , which cover C++, and part IV , which introduces Rust memory management. In part IV, we got through the basics of Rust memory management up through smart…
Over the past couple weeks I've been trying to work out how I want to store my game configuration. At first I started playing with XML, which was nice because I could stream a file rather than loading the entire thing into memory but I turned away from XML because …
In the jungle of new programming languages, Crystal is one of the most popular ones, but also the most mysterious. Let's take a look at it.
Nim community survey 2019 has been open for 50 days, and we have received 908 responses, which is our record-high number (771 in 2018, 603 in 2017). Before we go into details, we would like to thank all the people who took the time to respond. We really appreciate the feedback!
Swift for C++ Practitioners, Part 1: Intro & Value Types
Lately I’ve been experimenting with Rust, and I want to report some of whatI’ve learned about thread-safety. I am an enthusiastic dabbler in Rust: Ispend mo...
We're pleased to announce the 1.5 release of PyPy. This release updates PyPy with the features of CPython 2.7.1, including the standard libr...
I am convinced that if you want to start a rendering project from scratch, Nim is the best language to use.
Dr. John Ousterhout is a computer science luminary who has made significant contributions to the fie
Recto is a 2D programming language that uses nested rectangles as its core syntax, encoding structure and recursion directly in space instead of a linear stream of text. Recto explores new ways to write, parse, and reason about code—and even natural language—spatially.
Welcome! We here on the Python team at Microsoft are starting a blog. And since this is the first post, we wanted to give a bit of an introduction of who
The Recurse Center is a self-directed, community-driven educational retreat for programmers in New York City.
QuickCheck is the grandfather of property-based testing libraries. Despite being imitated in over thirty languages, the original implementation remains pre-eminent due to the type system and consistent logic of the Haskell language in which it is written.
I am a big fan of C, but some part of me always yearn to have just enough higher level constructs.
