The article explains why a monotonic clock is the appropriate fix and mentions testing with an injected clock jump. ### Source excerpt time.time() vs time.monotonic() in a Python scheduler: a backwards NTP step delayed runs by nine days. Monotonic durations and a jump-injecting test. ## Unlock a LUKS root over SSH on Fedora and Red Hat Enterprise Linux DevFeed: [Unlock a LUKS root over SSH on Fedora and Red Hat Enterprise Linux]() Original publisher: [Read original article]() Author: Josephine Pfeiffer Published: 2026-09-11T13:01:51Z Content type: tutorial Language: en Sources: [Red Hat](), [Red Hat Developer]() Topics: [Fedora](), [Linux](), [OpenSSH](), [ssh](), [systemd](), [datacenter](), [Network](), [Server]() Tags: [config](), [datacenter](), [developer](), [how-to](), [linux](), [network](), [red-hat](), [remote](), [rhel](), [server](), [ssh](), [systemd]() ### AI overview This tutorial explains how to unlock an encrypted LUKS root remotely over SSH on Fedora and Red Hat Enterprise Linux.

DevFeed: [What is WAL backpressure, and why does ClickHouse Managed Postgres need it?]() Original publisher: [Read original article]() Author: Kaushik Iska Published: 2026-08-05T15:58:59Z Content type: article Language: en Sources: [ClickHouse Blog]() Topics: [clickhouse](), [Database](), [systemd](), [Amazon EC2](), [benchmarking](), [Processes](), [Ubuntu]() Tags: [backend](), [benchmark](), [clickhouse](), [database](), [process](), [scale](), [storage](), [systemd](), [ubuntu]() ### AI overview ClickHouse Managed Postgres uses WAL-aware backpressure to prevent a full WAL disk from causing an outage.

Its SDKs also gain scope support, requiring applications to upgrade the SDK package and bundled native resolver together. ### Source excerpt Hi all, We've released SecretSpec 0.17 with: scopes: consumers can now resolve only the secrets it declares, instead of receiving an entire profile. Secrets caching for slow remote providers, with configurable freshness and explicit invalidation. Cross-secret validation, including "at least one" and "exactly one" credential groups. JWT/OIDC authentication for Vault and OpenBao. A new GitHub and Forgejo Action that resolves, masks, and exposes secrets to later workflow steps. Six new providers: SOPS, age, KeePass KDBX, OpenBao, Scaleway Secret Manager, and systemd credentials. All SecretSpec SDKs have been updated with scope support. This required an FFI change, so applications should upgrade the SDK package and bundled native resolver together. Read the release blog post post or see the GitHub release.
