Custom SpinLock implementation

Summary A developer attempted to implement a custom SpinLock in Rust based on Mara Bos’s book to protect shared mutable state across threads. The code resulted in memory safety issues (segmentation faults or undefined behavior) because the raw SpinLock was used to guard an UnsafeCell containing a String without adhering to Rust’s strict concurrency safety … Read more

Projecting a Text onto a wave Like Loft Prior tobextrude it

Summary A user attempted to project text onto a complex, wave-like surface generated in Grasshopper (a Rhino plugin) but encountered difficulties using the Surface Morph component. The core issue was attempting to use a single Loft surface to describe a compound geometry formed by pipes and connecting bows. Surface Morph requires a valid U-V coordinate … Read more

Pango passes wrong glyph indices to custom renderer

Summary We encountered a production rendering issue where a custom Pango renderer displayed incorrect glyphs. Instead of rendering the correct characters, the PangoGlyph indices passed to our draw_glyphs function were misaligned with the actual font mapping. For example, a lowercase ‘c’ (ASCII 99) resulted in a glyph index of 102 (ASCII ‘f’). This behavior was … Read more

underscore in folder name crashes “ignite scaffold module mymodule”

Summary An underspecified project root directory (space_chain) caused the Ignite CLI scaffold command to create protobuf directory structures with an inconsistent naming scheme (spacechain vs. space_chain). This mismatch triggered a panic in the gogoproto plugin because the physical file paths (spacechain/customcheck/params.proto) did not match the logical package qualifiers expected by the Go imports (space_chain/customcheck). The … Read more

USB Camera Video Not Displaying on Android

Summary The issue of a USB camera not displaying video on Android devices, despite working correctly on Windows and Linux, is a complex problem that stems from the camera’s UVC implementation. The root cause lies in the VideoControl interface not including an interrupt endpoint, which is incorrectly assumed to be mandatory by many Android USB … Read more

Drizzle ORM – TypeError: undefined is not an object (evaluating ‘relation.referencedTable’)

Summary A TypeError occurs when executing a relational query in Drizzle ORM (relation.referencedTable is undefined). This happens because the defineRelations configuration expects specific table names (workspaceMembers, workspaces, users) as keys, but the imported schema object uses a different key (workspaceMembers vs workspaceMember). Consequently, Drizzle fails to resolve the references during query building. The fix is … Read more
