Karl Seguin's Blog - A mix of coding and creative writing

Explores how memory is just bytes and the compiler's type system gives meaning to that memory in Zig. Demonstrates using @ptrCast to reinterpret memory as different types, covering extern structs for guaranteed layouts, built-in functions like @offsetOf for memory manipulation, and practical applications like building a memory pool allocator that reuses freed memory by treating it as linked list nodes.

Everything is a []u8

Fascinating read. Helped me understand memory layout and compiler rules a bit more.
Two mistakes I found in the writing:
<ul>
<li>The As raw memory section, this part seems a bit off in “at re-use memory”:</li>
</ul>
<blockquote>
That might not sound particularly useful, but using what we’ve learned so far, it can efficiently at re-use memory of discarded values.
</blockquote>
<ul>
<li>The very last paragraph in Conclusion is missing punctuation in “The trick”:</li>
</ul>
<blockquote>
For example, one that can be used for both User and Tea instances The trick,
