This is an opinionated essay about good and bad practices in data visualization. Examples and explanations are below.

How to spin before sleeping so that it actually helps and not harms?

Variables are the trickiest part of lambda calculus. And naming is the trickiest part of variables: the most complex code in our lambda evaluator is the part that renames variables to perform capture-avoiding substitutions.
Names are artificial tedious tags whose sole purpose is to aid human comprehension. Can we get rid of them? There ought to be a way to study computation without naming names.

The book, focusing on Homo sapiens, surveys the history of humankind, starting from the Stone Age and going up to the twenty-first century. The account is situated within a framework that intersects the natural sciences with the social sciences.

a whirlwind tour through the guts of the system

Tutorial about building a self-hosting cargo-compatible build tool. I have many problems with cargo and was interested in nixifying our job builds for eternity, so maybe there’s something useful there.

What if all software suddenly disappeared? What's the minimum you'd need to bootstrap a practical system? I decided to start with a one sector (512-byte) seed and find out how far I can get.

A paper about message-passing memory allocator: could be useful for actor systems.

MLIR is an interesting LLVM compiler framework thingy that uses LLVM for multiple representations instead of just high-level assembly.

This tutorial runs through the implementation of a basic toy language on top of MLIR. The goal of this tutorial is to introduce the concepts of MLIR; in particular, how dialects can help easily support language specific constructs and transformations while still offering an easy path to lower to LLVM or other codegen infrastructure. This tutorial is based on the model of the LLVM Kaleidoscope Tutorial.

Detailed explanation of futexes, including some possible pitfalls.

Ruby tutorial with very unusual and interesting writing style.

Category Theory Illustrated is a primer in category theory and other mathematical theories that is made to be really accessible to people with no prior exposure to the subject, without being dumbed down, by utilizing visual explanations.

Book about proofs with Lean.

A fresh take on typesetting

When it comes to security, we care about limiting access of each entity of a system to as few other entities as possible. Network input, executables and users must be able to reach only those resources, which are necessary to perform the defined server tasks. Principle of least priviledge.

Generally, it's better to implement as many layers of security as possible. Although, there is no way to make a server 100% bullet proof - it's a huge endless topic, this article covers some feasible essential systemd tunables that give us a layer of protection.

Abstract: Polymorphic inline caches (PICs) provide a new way to reduce the overhead of polymorphic message sends by extending inline caches to include more than one cached lookup result per call site. For a set of typical object-oriented SELF programs, PICs achieve a median speedup of 11%.

Introspectable and extensible IDEs with logic programming

In this blog post we explore how to write a type level contains operation for HList inspired type lists without running into overlapping trait implementations

To Mock a Mockingbird and Other Logic Puzzles: Including an Amazing Adventure in Combinatory Logic is a book by the mathematician and logician Raymond Smullyan. It contains many nontrivial recreational puzzles of the sort for which Smullyan is well known. It is also a gentle and humorous introduction to combinatory logic and the associated metamathematics, built on an elaborate ornithological metaphor.

Life is hard. Some days are at the absolute limit of what we can manage. Some days are worse than that. Eating—picking a meal, making it, putting it into your facehole—can feel like an insurmountable challenge. We wrote this cookbook to share our coping strategies. It has recipes to make when you’ve worked a 16-hour day, when you can’t stop crying and you don’t know why, when you accidentally woke up an Eldritch abomination at the bottom of the ocean. But most of all, this cookbook exists to help Sad Bastards like us feel a little less alone at mealtimes.

Presented in an experimental mnemonic medium that makes it almost effortless to remember what you read

It turns out that finite state machines are useful for things other than expressing computation. Finite state machines can also be used to compactly represent ordered sets or maps of strings that can be searched very quickly.

In August 2015 the U.S. National Security Agency (NSA) released a major policy statement on the need for post-quantum cryptography (PQC). This announcement will be a great stimulus to the development, standardization, and commercialization of new quantum-safe algorithms. However, certain peculiarities in the wording and timing of the statement have puzzled many people and given rise to much speculation concerning the NSA, elliptic curve cryptography (ECC), and quantum-safe cryptography. Our purpose is to attempt to evaluate some of the theories that have been proposed.

If you're curious about rainbows, colorimetry, gamma encoding, and experiments run in the late 1920s, then this is the post for you!

What if everything you think you know about addiction is wrong? One of Johann Hari’s earliest memories is of trying to wake up one of his relatives and not be able to. As he grew older, he realized he had addiction in his family.

A lot about sockets, syscalls and bits

The new Riptide garbage collector in WebKit leads to a five-fold improvement in latency in the JetStream/splay-latency test.

It’s extremely important to make sure your OAuth implementation is secure. The fix is just one line of code away. We sincerely hope the information shared in our blog post series will help prevent major online breaches and help web service owners better protect their customers and users.

WebKit's FTL JIT now uses a new backend on OS X — the Bare Bones Backend, or B3 for short, replaces LLVM as the low-level optimizer.

Designed to bring aggressive C-like optimizations to the largest variety of JavaScript programs.

Series of posts about how make C++ exceptions fast.
