+Recently I experimented with building the smallest possible static
+[x86-64][] [Linux][] binaries in a variety of programming languages.
+
+Each binary does the following:
+
+1. Print `hi!` and a newline to [standard output][stdout].
+2. Return an exit code of `0`.
+
+I tested [Assembly][], [C][], [Go][], and [Rust][] with a variety of
+optimizations and build options.
+
+Here's a plot of the results (**note:** [log scale][] X axis):
+
+{{< figure

+
+Here's a plot of the smallest static binary sizes (<1k, linear scale X
+axis):
+
+{{< figure
+ src="/files/posts/tiny-binaries/sizes-tiny.svg"
+ class=image
+ caption="Tiny Static Binary Sizes (<1k)"
+>}}
+
+Full Disclosure: `asm-opt` is the smallest *legitimate* result;
+`asm-elf` uses dirty tricks from [Tiny ELF Files: Revisited in
+2021][tiny-elf].
+
+Source code, build instructions, a [CSV][] of results, and additional
+details are available in the [companion GitHub repository][repo].
