The author discusses the challenges of effectively detecting systemic issues in complex distributed systems, emphasizing that creating useful alerts is both difficult and an art form. They highlight three main tenets regarding alerting: 1. **Complexity of Systems:** Instead of simply asking if a system is "up" or "down," it's more useful to ask specific questions about performance, like the normality of the API error rate, especially during incidents. 2. **Unpredictable Failures:** Predicting every possible failure in

Google is making significant changes to Android in 2026 to enhance malware protection across devices. Beginning in September, the company will restrict application sideloading through a developer verification program, requiring developers distributing apps outside of Google Play to provide identification, upload signing keys, and pay a $25 fee. This process has sparked criticism due to its complexity and burdensome nature for developers. To accommodate power users, Google introduced an "advanced flow" that allows them to bypass app verification, but this feature will be

The UK online safety regulator, Ofcom, has fined the US messaging platform 4Chan £520,000 for non-compliance with the Online Safety Act, largely for failing to implement age checks to protect children from pornography (£450,000). A lawyer for 4Chan, which has a history of refusing to pay fines, responded to the demand with an AI-generated cartoon of a hamster and argued that 4Chan operates legally under US law and is protected by the First Amendment. The remaining fines

Last December, Anthropic conducted a large-scale qualitative study with 80,508 Claude users from 159 countries, gathering insights on their hopes and fears regarding AI. The initiative aimed to capture a grounded vision of how AI could positively impact users' lives, moving away from abstract discussions about its risks and benefits. Participants interacted with an AI interviewer that asked standardized questions, adapting follow-up queries based on their responses. This approach enabled the collection of in-depth interviews while maintaining a high volume of responses. The

The text discusses the challenges of building a startup in a landscape where widely known methods can lead to a lack of differentiation among companies, increasing the likelihood of failure. It critiques past and present startup advice, pointing out that traditional strategies were inadequate for high-growth potential startups due to their reliance on long-range planning and slow adaptation. In contrast, "New Punditry" has introduced more effective frameworks that emphasize experimentation and adaptability. Notable methods include Steve Blank's customer development process, Eric Ries' Lean

The content describes a system for managing workflow loops in Claude Code, Codex, and OpenCode through a feature called "Cook." Users can access it by adding the `/cook` skill to Claude Code, with options available on GitHub and npm. Cook operates using three categories of tokens: prompts (core units), iteration and review loops, and parallel branches. Specific operators allow users to run tasks sequentially (xN), introduce review stages (review), and execute tasks in parallel (vN,

The content discusses the complex nature of modern kernel anti-cheat systems used in games on Windows. These systems operate at the highest privilege level, allowing them to intercept legitimate kernel callbacks, scan intricate memory structures, and function seamlessly while a game is active. It highlights the challenges of user-mode anti-cheat systems, which are limited by the trust model of operating at a lower privilege (ring 3). This means they can potentially be bypassed by higher-level processes (kernel drivers or even hypervisors

In my previous blog post, I discussed my passion for road networks and how infrastructure can be viewed as art, highlighting details often overlooked in games. While I focused on the artistic side initially, many readers wanted to know the technical aspects of my work. I emphasize the importance of the data representation in software, which I believe is fundamental to its success. Many developers rush to implement a data model without proper planning, which can lead to significant issues later, similar to changing plans during construction. My aim is

Tom Hartmann became a Software Mechanic unexpectedly, as this role did not exist seven years ago. Like many in the post-transition economy, he transitioned from a different profession; in his case, he was an agricultural equipment technician who specialized in fixing tractors and their control software. However, following the transition, the nature of software repair changed drastically—software could no longer be "fixed" but rather "regenerated" through user input. This shift meant that the job of diagnosing and fixing software problems now

Researchers from Aikido Security have discovered a new type of supply-chain attack involving the upload of malicious packages to repositories like GitHub. Between March 3 and March 9, they identified 151 such packages that use invisible Unicode characters to hide malicious code, making it undetectable in most code editors and review tools. This tactic complicates traditional defense mechanisms, as the visible portions of the code appear legitimate, often containing realistic changes like documentation updates and bug fixes. Aikido suspects the group

It transitions into a discussion about handling streams of events in programming, particularly contrasting reactive streams with plain Java. The author argues that many discussions overlook the potential of using asynchronous calls and multi-threading in Java to manage events efficiently without sacrificing application responsiveness. Two examples are presented that demonstrate processing streams of messages in parallel, handling success and error cases, and implementing backpressure

The content discusses the importance of both code quality and automated testing in software development, particularly in Ruby. A student asks whether to prioritize tests or code, prompting a metaphor about the relationship between bridges and their components. The master’s response emphasizes that both are essential, just like tests and the code they verify. Automated tests are crucial for ensuring program correctness, especially with the rise of AI-generated code. A comprehensive test suite containing various tests is necessary, but questions arise about how many tests are sufficient and

The article discusses how JavaScript handles date parsing, particularly through the `new Date(someString)` function. Unlike Python, JavaScript is quite flexible with date formats, which can lead to unexpected results. For example, it can interpret sentences or seemingly unrelated phrases as dates and produce bizarre outputs like incorrect years. The ECMAScript specification only mandates parsing for a subset of ISO 8601 formats, making the behavior of other input formats "implementation-defined." This leads to variations between different JavaScript engines
