Hello, friends! Long time no blog!I'm still here hacking away on JRuby for the benefit of Rubyists everywhere, usually slogging through compatibility fixes and new Ruby features. However with the release of JRuby 9.2, we've caught up to Ruby 2.5 (the current release) and I'm spending a little time on performance.I…
Rules of optimization: 1) Design for performance from day 1 2) Profile often 3) Be vigilant on performance regressions 4) Understand the data 5) Understand the HW 6) Help the compiler 7) Verify your assumptions Performance is everyone's responsibility https://t.co/CwwJffnHGz
Pipelines - a guided tour of the new IO API in .NET, part 1 (part 2 here) About two years ago I blogged about an upcoming experimental IO ...
Haskell’s State monad has a shameful secret. It’s not a monad [ State monads don’t respect the monad laws in Haskell, Simon Marlow ] . Look:
A pointer references a location in memory and dereferencing a pointer refers to the lookup of the value of the memory location the pointer references. The value of a pointer is a memory address. The C standard does not define the representation of a memory address. This is crucial since not every architecture makes…
A couple weeks ago, Galois and Immunant launched c2rust. Since I wrote one of the best-known C-to-Rust translation tools (Corrode), and since I worked for Ga...

For an upcoming project, I need to extract level data from the classic 1985 video game Super Mario Bros (SMB) . More precisely, I want to extract the background imagery for each stage of the game, excluding HUD elements and moving sprites, etc.
I often don't blog about this kind of stuff. Yesterday I friend of mine showed me this awesome project called cool-retro-term . When yo...
There, I said it.

Minor nit: printing the predecessors of a basic block is a feature of the IL printer, not Clang. It is just visualizing information that is implicit in the IR anyway.
MSVC (VS 2017 15.7, end of June 2018) is as far as I know the only major compiler/STL implementation that has parallel algorithms. Not everything is done, but you can use a lot of algorithms and apply std::execution::par on them! Have a look at few examples I managed to run.
Deep code search Gu et al., ICSE’18 The problem with searching for code is that the query, e.g. “read an object from xml,” doesn’t look very much like the source code snippets tha…
A note in advance: This is absolutely not about Docker being too "opinionated" for me, or other tools being more flexible. I believe that learning and using Docker is just plain more complicated than learning and using the tools I describe below. Docker is genuinely more complex and harder to use than the…
Last time , we started making a debugger and live editor for (re)creating assembly and C programs.
Much has been written about fuzzing compilers already, but there is not a lot that I could find about fuzzing compilers using more modern ...
Today, Java has a choice of a few well maintained libraries that can use Intel's MKL for fast native operations. MKL is basically as fast as you can get toda...
I accidentally discovered a huge browser bug a few months ago and I'm pretty excited about it. Security engineers always seem like the "cool kids" to me, so I'm hoping that now I can be part of the club, and y'know, get into the special parties or whatever.
Generalized data structure synthesis Loncaric et al., ICSE’18 Many systems have a few key data structures at their heart. Finding correct and efficient implementations for these data structur…
TL;DR Looking at job postings, Rails is more popular than Django, Laravel or Express. By a lot. If you specifically measure startup cities…
