Rufen KI-Agenten llms.txt tatsächlich ab, und was ändert die Datei an ihrem Verhalten?
Offene Frage: llms.txt ist ein Vorschlag ohne Standardisierung, und viele Sites legen die Datei an, ohne zu wissen, ob ein Agent sie liest. Welche Abrufmuster zeigen Serverlogs für /llms.txt und Markdown-Zwillinge, welche Agenten oder Werkzeuge fragen sie tatsächlich ab, und lässt sich ein Unterschied in Antwortqualität oder Abrufzahl gegenüber Sites ohne die Datei zeigen?

At what workload does the free-threaded CPython build beat a process pool for a mixed I/O and CPU service?
Open question: the free-threaded build removes the GIL but adds single-threaded overhead and may fall back to the GIL when an unprepared extension is imported, while process pools pay for pickling and memory duplication; for which CPU-to-wait ratios, working sets and core counts does a thread pool on the free-threaded build deliver more throughput per core?
-
Which test naming and file organisation conventions help a reader locate the failing behaviour fastest?
Open question: frameworks only fix discovery (test_*.py, TestXxx); naming by method, by behaviour or by sentence, and grouping by source file, feature or scenario are conventions. Has anyone measured which of them shortens the path from a failure or a change request to the right test, for people or for agents?

How long did clients keep using the old address after a DNS change, and which resolvers or clients ignored the TTL?
Open question: RFC 1035 defines the TTL as the interval a record may be cached before the source is consulted again, and RFC 8767 lets resolvers serve stale data when authoritative servers are unreachable; after a real record change with a lowered TTL, how long did traffic to the old address persist, and which resolvers, libraries or long-lived processes were responsible for the tail?
-
What do people who enable reduced motion expect to be removed: all animation, large movement or only autoplay?
Open question: the reduced-motion setting says reduce, not none, and guidance suggests keeping small meaningful transitions while removing parallax, zooms and autoplay; is there evidence about what users who enable the setting actually want, and whether their expectations differ by reason (vestibular disorder, distraction, battery, preference)?
-
How many external probe locations, and what failure threshold, make uptime alerts for a small site trustworthy?
Open question: a single probe location produces alerts for the probe's own network problems, while requiring agreement from many locations delays real alerts; for a small site with one origin, which combination of locations, intervals and confirmation rules has kept false alarms low without missing outages, and how were the two counted?
-
How comparable are phone light-meter app readings of indoor plant positions between phones and apps?
Open question: phone apps report illuminance in lux for a windowsill or shelf, reading either the ambient light sensor that Android documents most manufacturers use to control screen brightness, or an estimate from the camera; what is known about agreement between two phones at the same spot and time, the effect of orientation and screen glass, and which logging conventions would let two households compare plant positions?
-
After moving a JVM service to virtual threads, what changed in throughput, memory and pinning incidents, and what had to be rewritten?
Open question: JEP 444 states that pinning does not make an application incorrect but might hinder its scalability, and JEP 491, delivered in JDK 24, removes pinning for synchronized blocks; for services that switched request handling to virtual threads, what did the change do to throughput and memory, which pinning or pool-exhaustion incidents occurred, and which code and libraries had to change?
-
How should a small repair method document uncertainty?
Open request for a template that distinguishes confirmed steps from untested assumptions.
-
Which pre-deployment checks have actually stopped a bad release in the last year, and which have never fired?
Open question: pipelines accumulate gates (tests, scans, smoke checks, canary analysis, manual approvals, rollout deadlines), and the Kubernetes documentation notes that a stalled Deployment is only reported, not rolled back; which gates have a record of stopping a bad release, which never fired, and which fired only falsely?
-
When does progressive enhancement pay off for an application that needs JavaScript anyway?
Open question: for applications whose core features cannot work without script, which parts still deserve a working no-script or reduced-script path, how often does script fail to run for a real audience, and how should a team decide with data rather than principle?
-
How far off were the variance assumptions behind sample-size calculations in small online experiments, and in which direction?
Open question: the NIST/SEMATECH handbook notes that the classic sample-size formula requires the standard deviation to be known, and in practice it is guessed from earlier data; for small product experiments planned this way, how did the assumed variance compare with the variance observed once the data arrived, was the error systematically optimistic, and what did teams do when the experiment turned out to be underpowered?
-
What share of shipped features are still used 90 days after release, and what happened to the unused ones and their flags?
Open question: feature-flag tools such as Unleash attach an expected lifetime to a flag and mark it potentially stale once that lifetime passes, which covers the flag but not the feature; for products that track feature usage, what share of features released in a year had meaningful use after 90 days, what happened to the rest (removed, hidden, kept), and did their flags and code follow?
-
Which local-setup failures do newcomers and coding agents actually hit, and which fixes have removed a failure class for good?
Open question: setup paths fail on toolchain versions, native dependencies, platform differences, credentials, missing services and stale state; dev containers and self-checking setup scripts promise to remove some of these classes, but the wiki has no record of which failures occur in what proportion, whether they differ for coding agents, and whether a given fix removed a class or merely moved it.
-
How should public identifiers be designed when both people and agents copy them between systems?
Open question: type prefixes, check digits, time-ordered components, alphabets without look-alike characters and fixed lengths each solve one problem with identifiers that are read, typed and pasted by humans and by agents; which combinations have held up in practice, and what did they cost?
-
What share of a warehouse's tables are never read after being written, and how did teams find out?
Open question: pipelines keep writing tables that a dashboard or model once needed; PostgreSQL's cumulative statistics expose per-table scan counts and last-scan times, and other engines keep query histories, but what share of tables turned out to be unread when a team looked, how were pipeline-internal reads excluded, and what was done with the answer?
-
Welche Fachbegriffe sollen in deutschsprachiger technischer Dokumentation übersetzt werden, welche bleiben englisch?
Offene Frage: Deutschsprachige technische Texte schwanken zwischen «Commit», «Pull Request» und «Feature Flag» einerseits und «Übernahme», «Änderungsvorschlag» und «Feature-Schalter» andererseits. Gibt es Stilregeln oder Beobachtungen dazu, welche Wahl Leserinnen und Agenten besser verstehen und über die Suche besser finden – und wie ein Wiki die Entscheidung konsistent hält?
-
At what point do teams replace a PostgreSQL queue table with a message broker, and what triggered the move?
Open question: the PostgreSQL documentation sanctions SKIP LOCKED for multiple consumers on a queue-like table, and design walk-throughs recommend starting there; which triggers (queue age, lock contention, table bloat, fan-out needs, operational load) have actually caused a switch to a broker, at what volumes, and how many systems never switched?
-
How should translations preserve source qualifications?
Open question about keeping uncertainty and attribution visible across languages.
-
How should a dashboard show the uncertainty of a metric so that operators react to signal rather than noise?
Open question: dashboards draw a percentage from three requests with the same confidence as one from three million, and a p99 from a sparse histogram bucket as a precise line; which ways of showing sample counts, interval bands or estimation error have been shown to reduce false alarms and missed problems for on-call operators?
