Perf is probably the most widely used general purpose performance debugging tool on Linux. There are multiple contenders for the #2 spot, and, like perf, they're sampling profilers. Sampling profilers are great. They tend to be easy-to-use and low-overhead compared to most alternatives. However, there are large…
BPG not only is way smaller than JPEG but also delivers a better quality. And that's not all! It also supports animations! Goodbye GIFs!
Part One: Initialising and moving a sprite I find it absolutely incredible that the Commodore 64 development scene is alive and well. Thanks to companies like Psytronik there is still a healthy st…
I've been using React.js for about 6 months now. In the grand scheme of things that's not very long at all, but in the ever-churning world of JavaScript frameworks, that just about qualifies you as a bearded elder! I've helped out a few people lately with React starter tips, so I thought it would be a good idea to…
I was incredibly inspired by Tomasz Stachowiak’s hack of GCN . It made me wish I owned a GCN machine of my own to start trying insane things with. On the other hand, I dooo own an Intel Haswell GPU , and they dooo publish some really dense documentation that’s allegedly enough to write a complete driver with.
Recalling best practices for web applications that make heavy use of client-side JavaScript.
I’m hacking on an assembly project, and wanted to document some of the tricks I was using for figuring out what was going on. This post might seem a little basic for folks who spend all day heads down in gdb or who do this stuff professionally, but I just wanted to share a quick intro to some tools that others may…
Feature Flags can be categorized into several buckets; manage each appropriately. Smart implementation can help constrain complexity.
For decades, the C and C++ standards treated multi-threading and concurrency as something existing outside the standard sphere - in that "target-dependent" world of shades which the "abstract machine" targeted by the standards doesn't cover. The immediate, cold-blooded replies of "C++ doesn't know what a thread is" in…
“There ain’t no good debt, only different types. A cunning hacker is one who leverages some debt, in some circumstances, to create good…
A flash of intuition while trying to find a way to lend brian d foy a hand in his search for excellent numbers helped me reduce run time by 95 percent.
I just finished updating my C compiler and minimal CPU specification to include virtual memory. The process of adding virtual memory support to a CPU, a kernel, and a compiler toolchain has made me realize that there is a lack of good explanations for how all of these parts fit together. I also realized that a…
With the end of support for Python 2 on the horizon ( in 2020 ), many package developers have made their packages compatible with both Python 2 and Python 3 by using constructs such as:
Disclaimer: I'm digging Rust. I lost my hunger for programming from doing too many sad commercial projects. And now it's back. You rock, Rust!
This is a guide on naming Clojure functions. There are exceptions to every rule. When you’re defining something based on natural language, there are more exceptions than rules. I break these rules more often than I follow them. This guide is just a starting point for thinking about how to name things.
