Abstract. This tutorial provides a programmer ' s introduction to the Satisfiability Modulo Theories Solver Z3. It describes how to use Z3 through scripts, provided in the Python scripting language, and it describes several of the algorithms underlying the decision procedures within Z3. It aims to broadly cover almost…
When considering the panel to discuss concurrency, you’d be pushed to find a higher calibre than Sir Tony Hoare, Joe Armstrong, and Carl Hewitt.
This type of highlighting is ideal for assembly. With it, the things that shouldn't seem similar usually don't.
I’ve programmed systems in many different languages; from assembler to Java. I’ve written programs in binary machine language. I’ve written applications in Fortran, COBOL, PL/1, C, Pascal, C++, Java, Lua, Smalltalk, Logo, and dozens of other languages. I’ve used statically typed languages, with lots of type inference…
Earlier this year, many people were passing around this article about "re-learning how to be yourself online". Near the end the author reaches a set of questions that are motivating him:
Explore the Qt Blog for the latest insights on e.g. Qt Creator, your go-to source for cross-platform development tips and updates.
In modern applications, user interfaces often have to juggle multiple tasks at the same time. For example, a search component might need to…
Did you use to have some sort of intuition for what “lvalue” and “rvalue” meant? Are you confused about glvalues, xvalues and prvalues, and worry that lvalues and rvalues mi…
In this post, we will describe our quest to create Alfred–Margaret, the fastest Haskell implementation of the Aho–Corasick string searching algorithm, which powers string search in Channable.
How to use Wasmtime in a .NET application to load and execute WebAssembly code.
From two minutes to less than half a second!
Good judgement is the result of experience ... Experience is the result of bad judgement. — Fred Brooks
JavaScript and C both make you maintain your invariants the most painful way possible. Happily, there are better alternatives these days.
CSS Grid has been available in most major browsers since early 2017, and it makes web layout more powerful than ever before. But complex-looking new syntax (line-names! grid-areas! minmax! fit-content! ...
Just like last year, I made a list of the best media I enjoyed over the year. This includes music, films, series and games.
Get to know and learn how to use some less-known features of Version 12 of PostgreSQL. You'll surely discover something new for yourself.
While working on our Spectrum server , we noticed something weird: the TCP sockets which we thought should have been closed were lingering around. We realized we don't really understand when TCP sockets are supposed to time out!
Algebraic data types and algebraic data structures sound similar. It’s like they ought to be the same thing. But they’re not. They both have ‘algebraic’ in the name, so it’s confusing. I got them mixed up at times. Others have too. But, they’re different concepts. Understanding the difference will help if you’re…
How our mind falls short trying to short cut.
I've been enjoying using Go's database/sql package for working with databases. Recently, some mentions of gorm piqued my curiosity about using ORMs in Go vs. using database/sql directly. Having had some mixed experiences with ORMs in the past, I decided to start with a practical experiment by writing the same simple…
One of the anonymous reviewers of my recently published Storage Combinators paper ( pdf ) complained that hiding disk-based, remote, and lo...
How we migrated our Tier 1 service from ruby to rust and didn’t break production.
When I catch a bug before release I’m usually glad, because I’ve narrowly averted ruining someone’s experience or eating their data. Today I found a bug that I wish I hadn’t caught, a bug that I wish I’d released into the wild to witness in its full glory. I found this bug in my digital card game Ring of Worlds, and…
Dodrio is a new virtual DOM library that is designed to leverage the strengths of both Wasm’s linear memory and Rust’s low-level control by making extensive use of fast bump ...
Almost every one of you must have written a program, compiled it and then ran it to see the fruits of your hard labour. It feels good to finally see your program working, isn’t it? But to make all of this work, we have someone else to thankful too. And that is your compiler (of course, assuming that you are working in…
