In part one of this series we introduced the idea of a message log, touched on why it’s useful, and discussed the storage mechanics behind it. In part two, we discuss data replication. We have our log. We know how to write data to it and read it back as well as how data is persisted. The caveat to this is, although we…
The new Riptide garbage collector in WebKit leads to a five-fold improvement in latency in the JetStream/splay-latency test.
Performance budgets are an essential but under-appreciated part of product success and team health. Most partners we work with are not aware of the real-world operating environment and make inappropriate technology choices as a result. We set a time budget of less than 5 seconds first-load Time-to-Interactive and less…

Building your own UNIX shell in parts. This post explains how to execute commands.
The 1973 Fourth Edition of the Unix Programmer’s Manual doesn’t seem to be available online in typeset form. This is how I managed to recreate it from its source code.
systemd seems to be a dividing force in the Linux community. There doesn’t seem to be a middle ground to...
One of the least favorite habits of curl during all these years, I've been told, is when users forget to instruct the command line tool where to store the downloaded file and as a direct consequence, curl instead sends a lot of binary "gunk" to the terminal. The end result of that is at best … Continue reading curl…
Describes the process of building a QNX 7 x86_64 machine from (almost) scratch.
One of the things I’ve been doing this quarter is removing Gecko’s dependence on NSPR locks . Gecko’s (non-recursive) mutexes and condition variables now use platform-specific constructs, rather than indirecting through NSPR. This change makes things smaller, especially on POSIX platforms, and uses no dynamic memory…

X-Windows is the Iran-Contra of graphical user interfaces: a tragedy of political compromises, entangled alliances, marketing hype, and just plain greed. X-Windows is to memory as Ronald Reagan was to money. Years of "Voodoo Ergonomics" have resulted in an unprecedented memory deficit of gargantuan proportions…

If you don’t work in computers, you probably haven’t spent much time thinking about how data gets stored on computers or in the cloud. I’m…
We're excited to announce that in Windows 10 Fall Creators Update (FCU) due to ship in fall 2017, Windows Subsystem for Linux (WSL) will no longer be a
Another reason for optimizing compilers: It allows us to write simple and obvious code expecting that the compiler will do the optimization. This both reduces the initial defect count and makes the code more maintainable in the long-run. Note that these are also often the simplest optimizations (e.g. a calculation…
Hey there! My name is Michal 0xDEADB33F Ptaszek, and I’m a software architect at Riot. Today I would like to talk about communication. But not the kind of communication you’re probably thinking of. I want to talk about the other, more exci…

Sometimes programmers want to prune out characters from a string of characters. For example, maybe you want to remove all line-ending characters from a piece of text. Let me consider the problem where I want to remove all spaces (' ') and linefeed characters ('\n' and '\r'). How would you do it efficiently? size_t…
What if a secure device had an attacker-viewable crashdump format? What if that same device allowed putting arbitrary memory into the crashdump? Amazingly, the ps4 tempted fate by supporting both of these features! Let’s see how that turned out…
