📊Influence Sensor

See how captured your social feed is — analyze your Instagram/TikTok export 100% in-browser.

Audio monitoring that detects and alerts you about important sounds at home while you're away.

A single directory the user cannot read made compose watch fail to start, so nothing was watched at all: the ignore list is applied to events, never to the walk that registers the watches.

The EMV parser took each TLV length straight off the card, so tapping a crafted card wrote past several fixed-size fields and a stack buffer.

A reader writing to the emulated NFC tag at offset 1 shifted the stored payload by a byte and spliced in a stale byte from the previous frame.

A sharded query with EXISTS inside a CASE silently dropped half of its WHERE clause and returned the wrong rows.

An outer join against a reference table returned every preserved row once per shard instead of once.

A walrus nested inside a condition, as in if cond and (woo := 5) + n, left the variable optional in the branch where the assignment had certainly run.

Calling an abstract staticmethod or classmethod straight off the abstract class raised no error, even though instantiating that same class does.

DuckDB was modelled as returning NULL on division by zero, but it follows IEEE 754 and returns inf, so transpiled queries diverged.

The same unbounded EMV lengths as the unleashed fix, except here the stack overflow is not compiled out of the release builds the project ships.

The Type 4 Tag write fix, ported to the byte-identical copy of the file this firmware carries.

A constant condition in an if or for statement crashed the interpreter instead of reporting a compile error, taking down any program embedding it.

Using a package name as a value crashed the interpreter five different ways, and inside a return statement it raised no error at all and ran.

Every pull request had a red lint job: the pinned linter was built with an older Go than CI installs, so it panicked before reporting anything.

Instancing a variable font left the BASE table untouched, so instances kept the default baselines and a dangling variation store.

An infinite 2FA loop blocked report fetching: the anisette device identity was partly overwritten with random UUIDs. Behind seven reported issues.

A box with position: absolute stayed in normal flow and ignored its insets entirely, the last piece of CSS 2.1 positioning the engine was missing.

Any exception in a message handler surfaced as error sending request for url: the 200 response line was sent before the handler ran, so the dropped connection looked like a network fault.

A V4 message whose contents were written without the expected envelope was read as having no body at all, so the interaction verified successfully whatever the provider produced.
