Better Bash History (2012)
By default, the Bash shell keeps the history of your most recent session in the .bash_history file, and the commands you’ve issued in your current session are also available with a history call. These defaults are useful for keeping track of what you’ve been up to in the shell on any given machine, but with disks much…

UTF-8 String Indexing Strategies
When designing or, in some cases, implementing a programming language with built-in support for Unicode strings, an important decision must be made about how to represent or encode those strings in memory. Not all representations are equal, and there are trade-offs between different choices.

Why Codeless Software Is Doomed to Fail
Every couple of years, the hope surfaces that a simple graphical interface will replace teams of developers. Business people to quickly and easily create beautiful expressions of their ideas and launch them into production seamlessly. A handful of startups in every generation take up this challenge, and they mostly…

Rails is omakase (DHH)
There are lots of à la carte software environments in this world. Places where in order to eat, you must first carefully look over the menu of options to order exactly what you want. I want this for my ORM, I want that for my template language, and let's finish it off with this routing library. Of course, you're going…

Update on await syntax in Rust
In my previous post I said that the lang team would be making our final decision about the syntax of the await operator in the May 23 meeting. That was last Thursday, and we did reach a decision. In brief, we decided to go forward with the preliminary proposal I outlined earlier: a postfix dot syntax, future.await…

An x86 Assembler in 256 LOC (2017)
For the first “real” post in this blog, we’ll build an x86 assembler in less than 256 lines of C code. Obviously, it won’t implement every x86 instruction, but it will implement a surprisingly useful subset: data movement, control flow, integer arithmetic, bitwise operations, and function calls. We won’t be able to…

Syntax highlighters are wrong (2014)
Syntax highlighters make value judgments about code. Most highlighters judge that comments are cruft, and try to hide them. Most diff viewers judge that code deletions are bad.

On SQS
In my position I probably shouldn’t have a favorite AWS product, just like you shouldn’t have a favorite child. I do have a fave service but fortunately I’m not an (even partial) parent; so let’s hope that’s OK. I’m talking about Amazon Simple Queue Service , which nobody ever calls by its full name.
