Compiling Match Statements to Bytecode
2 days ago
- Go's headless switch statements are used as a replacement for if-else chains, demonstrated with a time-based greeting example.
- Purple Garden introduces a 'match' statement as the singular control structure, simplifying conditional logic with a clear syntax.
- The match statement in Purple Garden requires all branches to resolve to the same type and includes a mandatory default branch.
- Purple Garden's architecture is based on an intermediate representation (IR) that uses SSA (Static Single Assignment) form, enabling optimizations and decoupled code generation.
- The parsing process in Purple Garden involves lexical analysis followed by the construction of an abstract syntax tree (AST), with error handling for syntax errors.
- Type checking in Purple Garden is straightforward, ensuring match conditions are boolean and all branches return the same type, with clear error diagnostics for violations.
- Lowering the AST to IR involves creating basic blocks for conditions and bodies, including a joining block to merge control flow paths.
- The bytecode generation process translates the IR into executable instructions for a virtual machine, with optimizations like constant loading and jump elimination.
- A factorial function example demonstrates recursion and the match statement's use in Purple Garden, showcasing the language's capabilities.

LLM Doesn't Write Correct Code. It Writes Plausible Code
3 hours ago
- LLMs generate plausible but often incorrect code, as shown by a Rust rewrite of SQLite being 20,171 times slower in primary key lookups.
- The Rust rewrite misses critical optimizations like the `is_ipk` check for INTEGER PRIMARY KEY columns, leading to full table scans instead of efficient B-tree searches.
- Another issue is unnecessary `fsync` calls on every INSERT statement, making operations significantly slower compared to SQLite's optimized approach.
- LLMs optimize for plausibility over correctness, producing code that compiles and passes tests but fails under real-world performance scrutiny.
- Studies like METR's randomized trial and GitClear's analysis show that AI-generated code often leads to slower development and more copy-pasted, less refactored code.
- SQLite's performance comes from decades of optimization, including zero-copy page caching, prepared statement reuse, and schema cookie checks—details LLMs miss.
- The gap between LLM-generated code and correct implementations highlights the need for developers to define and measure specific correctness criteria when using AI tools.

C# strings silently kill your SQL Server indexes in Dapper
6 hours ago
- C# strings passed to Dapper queries can cause SQL Server to perform implicit conversions (CONVERT_IMPLICIT) from varchar to nvarchar, leading to full index scans instead of seeks.
- The default mapping of C# strings in Dapper is nvarchar(4000), which mismatches with varchar columns in SQL Server, degrading performance.
- Implicit conversions can significantly increase CPU usage and logical reads, especially in queries executed frequently.
- The fix involves explicitly specifying the parameter type as DbType.AnsiString for varchar columns using DynamicParameters or DbString.
- Matching parameter types to column types and sizes is crucial for optimal query performance and efficient use of cached query plans.
- Auditing Dapper queries for string parameters passed to varchar columns can uncover hidden performance issues.
- Adding comments to explain the use of DynamicParameters or DbString can prevent future refactors from reintroducing the performance problem.
- Tools like SQL Server Query Store and execution plans can help identify queries suffering from implicit conversions.
