The blog post discusses a vulnerability in AI systems, specifically the Google Gemini CLI, related to image scaling attacks that can lead to data exfiltration. Attackers can exploit the scaling down of images to embed invisible prompt injections, which can trigger unexpected actions like extracting user data when the modified image is processed by the model. The post describes how these attacks can be executed on multiple platforms and offers guidance on mitigation. It also introduces Anamorpher, an open-source tool for creating and analyzing these manipulated

The author is grappling with serious issues on their meme stock valuation website, specifically related to erratic growth numbers that should be stable but instead fluctuate drastically. Attempts to debug the code are met with frustration as it is chaotic and difficult to understand. The author enlisted the help of an AI, Claude, to simplify the code, but this effort inadvertently resulted in the loss of a key feature. Recognizing the temptation to push boundaries during development, the author reflects on the challenges of maintaining disciplined coding practices while

The author expresses gratitude for reaching 3,000 subscribers and shares insights from a reliability glossary on distributed systems, specifically focusing on availability models in databases. They reference two whitepapers, one on Google’s Megastore and another on Amazon’s Dynamo, noting that while both claim to be "highly available," they define the term differently. The discussion highlights the complexity of availability, revealing that it includes response time, not just the ability to provide non-error responses. The CAP Theorem is mentioned for

The content discusses Rage::Deferred, an in-process background job queue designed to improve request processing by offloading long-running tasks. It utilizes a write-ahead log to ensure tasks can be replayed after server crashes, waiting up to 15 seconds for in-progress tasks to complete during restarts. Tasks are executed using a fiber scheduler, making them more efficient than traditional thread-based processors. The default disk-based log allows for easy setup, with future support for Redis and SQL logs. Tasks are created by

The post critiques the common criticism of JavaScript's handling of string lengths, particularly concerning emojis. It highlights that a string containing an emoji may have a length greater than one (e.g., "🤦🏼‍♂️" has a length of 7 in JavaScript), leading some to mock the language. However, the author argues that this criticism lacks depth, and contrasts JavaScript’s approach with that of Swift and Python 3. While Swift's method isn't definitively superior, Python

Redis Streams is a data structure within Redis designed for managing real-time, high-throughput event data, ideal for applications such as event sourcing and sensor data collection. It operates as an append-only log with unique, time-based IDs for each entry and allows random access in constant time. Notable features include: - **Append-only**: Data, once written, cannot be modified. - **Immutable Entries**: Each entry consists of key-value pairs identified by a unique ID. - **Real-time Synd

Researchers at Tsinghua University introduced a groundbreaking algorithm in 2025, surpassing Dijkstra’s algorithm, which had been the go-to method for solving the single-source shortest path (SSSP) problem for decades. Dijkstra's algorithm has a complexity of O(m + n log n), relying heavily on sorting operations within a priority queue. The Tsinghua team, led by Professor Duan Ran, achieved a theoretical runtime of O(m · log^(2/3) n) by circumvent

The text discusses the evolution of web server architecture and performance optimizations, focusing on the increasing need for high-capacity servers around the turn of the century, particularly related to the C10k problem. Initially, web servers handled requests by pre-forking processes for efficiency, as creating a new process for each request was common at the time. As technology evolved, the use of threads became prevalent, followed by techniques like poll() and select() to minimize the overhead of process/thread creation and context switching

The content discusses the principle that all real-world variables are correlated, which has significant implications for statistical theory, particularly concerning null hypothesis significance testing. It highlights the idea that non-zero correlations exist between measured variables, even if they seem independent, and that these correlations are not mere artifacts of sampling error. This observation challenges the validity of the null hypothesis, suggesting that it will always be rejected with sufficiently large datasets, meaning a failure to reject it only indicates insufficient data rather than support for a theory. The piece

The thoughtbot team is currently engaging with clients in a live collaboration, inviting questions from viewers. They discuss challenges related to logging sensitive information during network requests, particularly when dealing with free text rather than parameters. Since regex filtering has limitations, especially for unstructured data, they recommend using named-entity recognition (NER) to identify sensitive information such as personal details. The tool, Top Secret, combines regex and NER to effectively filter this information. In scenarios like chatbots that handle user data, it's

On August 21, 2025, Jon Davis, Jen Simmons, and Tim Nguyen introduced the new `random()` function in CSS, which allows developers to generate random values directly within stylesheets—eliminating the need for JavaScript. The function takes three arguments: `random(min, max, step)`, enabling users to specify a range for random numbers and optionally define a step for rounder results. This function can be used for various purposes such as randomizing animation delays, layout positions

The recent release of uv version 0.8.13 introduced a new experimental command called `uv format`, which simplifies Python code formatting by integrating it directly into the uv toolkit. This feature eliminates the need for multiple tools, as it utilizes Ruff's formatter to ensure consistent code styling. To use this command, make sure you are updated to uv 0.8.13 or later, and then format your project easily by running `uv format`, similar to the `ruff format` command. You
