A claim has surfaced suggesting that OpenAI's GPT-6 Astra model broke an Enigma-encrypted message that had resisted decryption since 2005. The details appear linked to a page on cryptocellar.org, a site dedicated to cryptographic history and cipher challenges. The story gained brief traction on Hacker News, receiving 20 points and 3 comments. Insufficient article content is available to independently verify the specific claims or methodology involved.
A high-severity vulnerability chain dubbed Click2Shell affects WordPress Core versions 7.1.0 and select releases across branches 7.0 through 4.8, allowing unauthenticated attackers to trigger remote PHP execution. By luring an administrator to a crafted URL, the flaw exploits a selector injection in WordPress Core that automatically installs an official theme from the WordPress.org catalog without any explicit admin action. When chained with a vulnerable theme, a follow-on request to admin-ajax.php causes the inactive theme's functions.php to load and fetch an attacker-specified plugin ZIP, ultimately executing arbitrary PHP under the server's web worker account. WordPress has released patched versions — including 7.1.1, 7.0.5, 6.9.8, and 4.8.31 — with fixes backported across all affected branches. Administrators are advised to update immediately, remove unused themes, and restrict outbound traffic and plugin installation permissions as additional mitigations.
PR Tour, an open-source code-review skill built for Codex and Claude Code, has released version 0.7.0 with a new transition feature that lets readers inspect the source evidence behind step-to-step explanations. The update was prompted by a GitHub suggestion from contributor imMamdouhaboammar, who noted that connections between steps were often left implicit even when individual steps were well-documented. Authors can now attach optional transition objects to each step, citing specific file paths and line ranges from Git — including unchanged files outside the diff — to justify why the guide moves from one section to another. Transitions fall into three categories: source-cited, includes-inference, and reading-order, giving authors a way to be transparent about what is verified versus interpreted. The release also introduces draggable desktop layout dividers with keyboard support and offline-readable source excerpts, while remaining backward-compatible with older guide manifests.
When measuring API or distributed system performance, relying solely on average response times can obscure how slow the system is for a significant portion of users. Percentiles such as P50, P95, P99, and P99.9 provide a clearer picture by showing the response time thresholds experienced by different proportions of users. For instance, a P99 of 3 seconds means 1% of requests exceed that time — which can translate to 10,000 affected users out of one million requests. These slower requests, known as tail latency, are especially critical in high-traffic systems like e-commerce platforms where even a small percentage of delays impacts real users. Percentiles also underpin Service Level Objectives and Service Level Agreements, making them a key tool for setting and enforcing performance standards.
