Emily St. John Mandel's New Novel Explores What It Means to Vanish from the State

Emily St. John Mandel's upcoming novel 'Exit Party' centers on a world where individuals can be erased from official existence. In the story, becoming a 'ghost' is not a voluntary escape but a consequence of crossing the government. The narrative follows a secret agent who discovers how little it takes to fall off the grid against one's will. An excerpt from the book has been published by Wired, offering readers an early glimpse into its themes of surveillance and state control.

HTTP 200 Status Alone Can Mask Broken Dependencies in Uptime Kuma Monitors

Uptime Kuma, a self-hosted monitoring tool, can falsely report a service as 'UP' even when a backend dependency like a database has failed, as long as the endpoint returns HTTP 200. Testing with version 2.5.3 showed that both status-code-only and broad keyword checks passed a response where the database field explicitly read 'down'. This happens because HTTP 200 only confirms the response was received, not that the underlying services are functioning correctly. Using the JSON Query monitor type to check a specific response field — such as checks.database — correctly detected the failure in all tested scenarios. Developers are advised to configure targeted JSON queries and verify alert delivery separately before relying on a green status badge.

How to Use DelegatingHandler to Build Middleware Pipelines for HttpClient in .NET

The DelegatingHandler class in .NET's HttpClient allows developers to build a chain of interceptors that process every HTTP request and response in sequence. Modeled after the Chain of Responsibility design pattern, each handler in the pipeline can inspect or modify requests before passing them along, and responses on the way back. Practical use cases include logging request durations, automatically injecting authentication tokens, propagating correlation IDs across microservices, and recording performance metrics. Multiple handlers can be registered and chained together using the IHttpClientFactory configuration in the dependency injection setup. This approach centralizes cross-cutting concerns and eliminates repetitive boilerplate code scattered across HTTP call sites.

Hawaii's Guinea Grass Spreads Wildfire Risk With 9,000 Seeds and 9-Foot Growth

Guinea grass, originally introduced to Hawaii in the 19th century for grazing purposes, has since become a serious ecological threat across the islands. The invasive perennial can grow up to nine feet tall and produce as many as 9,000 seeds per plant, enabling rapid and widespread proliferation. Its ability to recover quickly after fires makes it a significant contributor to wildfire risk by supplying large amounts of combustible fuel. The species serves as a cautionary example of how imported plants can cause lasting and unintended environmental damage.

Satya Niketan Collapse: Legal Experts Say Disclaimer Clauses Won't Shield PG Owners

A building collapse in Delhi's Satya Niketan locality claimed seven lives and left several others injured. The incident has raised questions about whether disclaimer clauses in rent agreements can protect PG owners from legal liability. Legal experts have clarified that such clauses cannot override statutory duties or excuse negligent conduct. Victims' families may still pursue compensation provided they can establish negligence and a direct causal link. Ongoing investigations are expected to determine the extent of responsibility of both property owners and relevant authorities.

Developer builds reproducible Erlang learning environment using Nix flakes

A developer learning Erlang has published a GitHub repository combining a Nix-based development shell with small experimental programs written during the learning process. The setup uses Nix flakes to pin the environment to a specific Nixpkgs revision, ensuring that Erlang/OTP 29.0.6 is used consistently by anyone who clones and enters the shell. The repository is structured around two components: a flake.nix configuration file and a directory of programs written while working through the book 'Learn You Some Erlang for Great Good!'. The environment is deliberately minimal, currently including only Erlang itself, with tools like Rebar3 left out until more complex projects require them. The developer notes the setup may expand over time as the scope of their Erlang experiments grows.

Why Most Customer Churn Models Fail — and What Actually Fixes Them

Most churn prediction programmes share a core flaw: they rank customers by likelihood of leaving rather than by how likely they are to respond positively to intervention. This means retention campaigns often waste resources on 'lost causes' who have already decided to leave, 'sure things' who would have stayed anyway, and 'sleeping dogs' who are actually pushed to cancel by being contacted. Experts recommend uplift modelling, which estimates the change in churn probability caused by an intervention, requiring randomised treatment data to measure true responsiveness. Involuntary churn from failed payments should also be separated out before model training, as it corrupts results and is better addressed through payment-retry logic and pre-expiry reminders. Additionally, data leakage from outcome-encoded features is a common reason churn models show inflated validation scores that do not hold up in production.

Karnataka Hurdler Krishik Dropped from Asian Games Squad Despite Meeting Qualifier Thrice

Karnataka hurdler Krishik M has been left out of India's Asian Games athletics squad despite clearing the qualifying standard three times. The Athletics Federation of India cited his third-place finish at the recent Inter-State meet as grounds for his exclusion. Critics have raised concerns over inconsistent selection criteria, noting that other athletes were treated more leniently. Krishik, however, remains determined to compete in future events and continue meeting qualification benchmarks.

Per-seat AI coding tools waste idle capacity while heavy users hit limits early

Companies paying for per-seat AI coding subscriptions routinely lose unused capacity each week because allowances expire rather than roll over, while some engineers exhaust their allocation by mid-week. Usage is highly uneven across roles — engineers deep in migrations may max out for weeks, while those in meetings or non-coding roles barely touch their seats. The practical fix, according to the analysis, is redistributing work items to colleagues with spare capacity rather than sharing credentials or buying additional seats, both of which create new problems. This approach requires tasks to be clearly documented so they can be handed off, which the author notes is a prerequisite for good AI-assisted workflows in general. Any gains from this method should be counted as throughput improvements rather than cost savings, since money is only truly saved if the alternative would have been purchasing more seats.

Hidden Markov Model strategy doubles Sharpe ratio and cuts drawdown by 65%

A developer built a real-time market risk scoring system using a Gaussian Hidden Markov Model (GaussianHMM) trained on five years of data from five assets, including SPY, gold, and bonds. The model identifies three hidden market regimes — Bull, Neutral, and Bear — without manual labeling, using the Baum-Welch algorithm to learn transition patterns from returns and volatility. Based on the detected regime, the strategy dynamically adjusts portfolio exposure, going fully invested in bull markets and defensive during bear phases. Backtesting results showed a Sharpe ratio of 2.12 versus 1.11 for a buy-and-hold approach, while maximum drawdown shrank from -21.9% to -7.5%. The author argues that HMMs offer an honest way to capture regime shifts that traders sense intuitively, without overfitting to exact price predictions.
