The content discusses challenges faced by Ruby developers, particularly regarding runtime errors that are hard to catch, unlike in stricter compiled languages. It emphasizes the difficulties of debugging in Ruby and introduces the idea that solutions to these problems vary based on what a developer is optimizing for. The author advocates for using linters in development to catch issues early, providing guidance on how to implement them in a Ruby application (e.g., in the Gemfile) and how to selectively enable or disable rules. Additionally, the author

Cloudflare offers a serverless computing solution that allows customers to run code globally at high speeds with minimal cold startup times. Unlike traditional models that rely on containers or Kubernetes, Cloudflare utilizes a V8-powered architecture to achieve sub-millisecond latency and support numerous tenants who can operate independently without shared memory or state. Traditional serverless instances, often dependent on containers or VMs, can take between 500 milliseconds to 10 seconds to spin up, leading to unpredictable execution times. In contrast, Cloudflare

On October 31, 2024, Justine shared on her webpage that she learned 42 programming languages in a month to create a new syntax highlighter for "llamafile." She highlighted some of the most intriguing syntax features she encountered. The languages supported include Ada, Assembly, BASIC, C, and many others, covering nearly all on the TIOBE Index except Scratch. Justine noted that implementing a syntax highlighter isn't particularly difficult and could be done in a job interview context.

The author revisits concepts of rate limiting, specifically focusing on Exponential Rate Limiting (ERL) after discussing Generalized Token Bucket (GCRA) and leaky bucket algorithms. ERL employs an exponentially-weighted moving average to assess a client's request rate, allowing more adaptable policy enforcement since the rate can be measured meaningfully even without back-pressure. Each client in an ERL system has stored data similar in space requirements to the leaky bucket but requires more complex floating-point calculations. Unlike

The manuscript, authored by Sean W. Cain and Andrew J. K. Phillips, investigates the relationship between sleep regularity and mortality risk, showing that sleep regularity is a more significant predictor of mortality than sleep duration. The study, conducted using data from 60,977 participants in the UK Biobank, analyzed over 10 million hours of accelerometer data to derive Sleep Regularity Index (SRI) scores. The results indicated that higher sleep regularity was associated with a 20% to

The article discusses the importance of using multi-stage builds in Docker to eliminate unnecessary bloat in container images. When Dockerfiles aren't multi-stage, they often include build-time dependencies that are unnecessary for production, increasing both image size and security risks. The article outlines common sources of this bloat and emphasizes the distinction between build-time and run-time dependencies, noting that build-time dependencies typically contain more vulnerabilities. It advocates for separating the build and run environments to create slimmer, more secure images by avoiding the inclusion of

The article by Raffi Hotter and colleagues discusses functional ultrasound imaging (fUSI), a promising technology for imaging brain activity with higher spatial resolution than fMRI and the potential for compact, affordable hardware. While fUSI has been mainly used in invasive experiments on rat brains, the authors explore the possibility of performing fUSI non-invasively with the skull intact. They highlight the skepticism they encountered regarding this approach, particularly concerning the reported 22 dB/cm/MHz attenuation of ultrasound through

The Google Project Zero team announced the evolution of their framework for large-language-model-assisted vulnerability research, originally called Project Naptime, into Big Sleep, a collaboration with Google DeepMind. They revealed that Big Sleep successfully identified its first real-world vulnerability—a stack buffer underflow in SQLite—shortly after its discovery in early October. This issue was reported and fixed by the SQLite developers on the same day, preventing any impact on users since it was uncovered before an official release. This achievement marks a significant

Jamie Lawrence shares his experiences with Heroku, highlighting its initial value in allowing Podia to innovate quickly without heavy infrastructure management. Despite early satisfaction, his enthusiasm waned after Salesforce's acquisition, as Heroku began to feel stagnant and less user-friendly due to mandatory Salesforce logins and deteriorating sales support. Podia had a plan to switch to self-managed infrastructure if their Heroku bill surpassed $20k/month, which has not occurred in 9 years. They fully utilized Heroku's features,
