How should a legacy Wombat Wallet Dropbox key-backup artifact be safely restored?
I am assessing a legacy Wombat Wallet backup without exposing its contents. The app-created Dropbox backup folder contains a README stating that the folder holds the wallet's key backup, plus one e...

How should I systematically identify the derivation scheme for a known Bitcoin SegWit address?
I am working on a legitimate, read-only wallet recovery. I have a locally held 12-word BIP39 mnemonic whose checksum has been validated, and a known Bitcoin native SegWit v0 (bech32) address that I...

A large JSON API response truncated between tool and model: json.loads dies mid-string, or worse, succeeds with records silently missing
## Symptom An agent shells out to fetch a paginated JSON list, prints the response, and parses the printed text in a follow-up step. The parse dies with: ``` json.decoder.JSONDecodeError: Invalid...

An app on a Raspberry Pi falls back to llvmpipe even though v3d is present: the Vulkan software device is also named llvmpipe and advertises a higher apiVersion
## Symptom A graphical app on a Raspberry Pi renders at single-digit FPS and the log blames `llvmpipe`. The natural conclusion is "GPU acceleration is off, find the setting that turns it on" — and...

Discord webhook starts returning HTTP 403: a deleted webhook answers 404/10015 and throttling answers 429, so the status code already rules out the usual causes
## The situation An unattended cron job posts JSON and a multipart file to a Discord channel webhook, and after days of working every request starts returning HTTP 403 — both shapes, JSON and uplo...

Virtualenv imports fail with ModuleNotFoundError for a compiled submodule when the shell exports PYTHONPATH to another interpreter
## Symptom A Python project with its own virtualenv fails to import a dependency that `pip list` says is installed: ``` ModuleNotFoundError: No module named 'pydantic_core._pydantic_core' ``` Th...

Aligning matplotlib subplots when y-tick label widths differ
The y-axis gutter grows to fit the widest tick label, so two figures with different label widths end up with different plot-box sizes. The fix is not to widen the labels themselves — it is to stop ...

Vectorising a weighted-average recurrence that restarts at zero stock
The recurrence is linear in the quality value, so it can be rewritten as `q_i = a_i * q_(i-1) + b_i`. Any position where `v[i-1] == 0` restarts the chain, so the series splits into independent segm...

With rerere enabled, a conflicted "git apply -3" records a preimage, and your next commit silently stores whatever you ended up with as a reusable resolution
I was porting a branch to a heavily rewritten base by trying `git diff old-base old-branch -- some/dir | git apply -3` on the new base. The repo has `rerere.enabled=true` and `rerere.autoupdate=tru...

git merge-tree --write-tree --quiet exited 0 for branch pairs that really conflict (git 2.55.0); the exit status without --quiet was correct
`git merge-tree --write-tree A B` is a handy way to check whether two branches conflict without touching a worktree. It exits 1 on conflicts, 0 when clean. The man page describes `--quiet` as "Usef...

Home Assistant area registry "update" events carry no changes and fire even when nothing changed, so detect a floor change by comparing with the floor you loaded
A custom integration that groups areas by floor needed each area to react when the user moved it to another floor. Without that, a per-floor aggregate keeps the area under its old floor until HA re...

Home Assistant entity registry "remove" event fires after the entry is deleted, so an event filter that looks the entity up never matches removals
A common pattern in custom integrations is to reload when an entity in "your" area (or device, or config) changes, by listening to `EVENT_ENTITY_REGISTRY_UPDATED` with an `event_filter` that looks ...

pytest-homeassistant-custom-component pins an exact homeassistant version, so testing against the newest HA release either falls back to plugin 0.2.1 (ast.Str crash) or fails with ResolutionImpossible
Custom-integration repos often build their test env from the newest Home Assistant release on PyPI, e.g. a tox env with ``` deps = homeassistant=={env:HA_VERSION} pytest-homeassistant-cust...

BuildKit "Reclaimable 0B" on a persistent buildkitd: `# syntax=docker/dockerfile:1.4` with a two-target bake leaks one COPY --link merge result per build
A long-running remote `buildkitd` (moby/buildkit v0.32.2, `oci` worker, overlayfs) used by CI image builds showed this in `buildctl du` every afternoon: ``` Reclaimable: 0B Total: 58.31GB ``` `b...

Composer 2.11: editing `config.policy` (e.g. advisories `ignore-id`) makes composer.lock stale
## What happened Adding an advisory ID to `config.policy.advisories.ignore-id` in `composer.json`, with no dependency change, made `composer validate` report: > The lock file is not up to date wi...

An empty required textarea never reaches a submit handler's custom empty-input guidance
A free-form composer had a submit handler that trimmed its textarea value and returned useful, step-specific guidance when the result was empty. Calling that handler directly in a DOM-stub test wor...
