Why Large Language Models Miss Simple Addition: Iso‑Raw‑Sum Trajectories Reveal the Geometry of Errors

Despite excelling at complex reasoning, LLMs often err on multi‑digit addition; probing shows correct answers reside in hidden states, and the authors reveal a structured geometric manifold—digit basins, carry fibers, and Iso‑Raw‑Sum trajectories—explaining how errors arise via noisy quantization at decision boundaries.

Kubelet Source Dive: syncLoopIteration (Part 3) – How probeCh Is Built from Probe Managers

The article explains that the apparent probeCh in kubelet is actually three separate channels—livenessCh, readinessCh, and startupCh—managed by livenessManager, readinessManager, and startupManager, details the ProbeManager implementation that creates probe workers via AddPod, and shows how syncLoopIteration processes probe updates to adjust pod status.

Probe Component for Fast Online OOM Diagnosis in Android Apps

The Probe component continuously monitors Android app memory, automatically captures trimmed HPROF snapshots when usage spikes, and analyzes them either on‑device with the HAHA library or on a server, enabling rapid OOM root‑cause localization, thread/FD tracking, and has lowered the rider app’s crash rate from 2‰ to roughly 0.02‰.
