### AI overview

Vercel CLI can now query Speed Insights datapoints, including Core Web Vitals and other page performance metrics collected from real user traffic. The feature supports investigating regressions and comparing performance across pages, regions, and device types.

### Source excerpt

You can now query Speed Insights datapoints directly through the Vercel CLI. Using the vercel metrics command, you can pull core Web Vitals (LCP, INP, CLS) and other page performance metrics (FCP, TTFB) based on client-side measurements from real user traffic. By providing a coding agent access to the CLI, an agent can answer questions such as: Which pages' INP have regressed since last week? How is the perceived speed of my home page in Asia? Compare the CLS of the dashboard between mobile and desktop. For more details on how to use the CLI command and a complete list of supported metrics, dimensions, filters, and query options, explore the documentation. Read more

Transforming Frontend Architecture: A Journey from Monolith to Micro Frontends at Udemy -- Part 3 of 3 By: Chris Nienhuis, Hamza Erbay, Matthew Bise, Nathan Chapman, Seth Hodgson, Trey Briggs, Charles Pham Photo by Venti Views on UnsplashIntroduction In the previous section, we walked through the Udemy Hackathon event, and the decisions and preparations made that laid the foundation for our move toward a more modular frontend architecture. In this section, we will focus on the implementation of our vision post-Hackathon, how we are planning to execute the migration, and the impact it has had so far. If you missed Part 1 and Part 2 of this series, you can find them here: Transforming frontend Architecture: A Journey from Monolith to Micro frontends at Udemy -- Part 1... Transforming frontend Architecture: A Journey from Monolith to Micro frontends at Udemy -- Part 2... Post-Hackathon: Implementing the Vision Following the green light from the Shark Tank jury, we've taken decisive steps to translate our hackathon prototype into a scalable and robust frontend architecture. A dedicated frontend team has been formed at Udemy with the express purpose of driving this evolution. "Where the journey began... A throwback to the spark that ignited our incredible voyage. Thanks to Gregg (our former CEO) for recognizing the hard work! #Milestone #Hackathon #OriginStory" Our commitment to this new direction is reflected in a series of strategic actions: Migration Guidance: We've laid out clear guidelines for transitioning (transitioning implies migration) from the monolithic application, ensuring a smooth and structured shift to the new architecture. Collaboration with Design Systems: By partnering with the design system team, we've begun decoupling foundational components and design tokens, packaging them into shared npm packages. This initiative is critical for consistency and efficiency across all applications. Education and Alignment: Recognizing the importance of knowledge sharing, we

### Source excerpt

Heads up, we've moved! If you'd like to continue keeping up with the latest technical content from Square please visit us at our new home https://developer.squareup.com/blogPySurvival is an open source python package for Survival Analysis modeling. Today, we're excited to introduce PySurvival, a python package for Survival Analysis modeling. This article is the first installment in a four part series, which will include tutorials designed to demonstrate how to easily make the most of the package. You can also find these tutorials on the official website: Churn modeling Predictive maintenance Credit risk PySurvival LogoWhat is PySurvival ? PySurvival is an open source python package for Survival Analysis modeling -- the modeling concept used to analyze or predict when an event is likely to happen. It is built on top the most commonly used machine learning packages: NumPy, SciPy, and PyTorch. PySurvival provides a very easy way to navigate between theoretical knowledge on Survival Analysis and detailed tutorials on how to conduct a full analysis, as well as build and use a model. The package contains: 10+ models ranging from the Cox Proportional Hazard model and the Neural Multi-Task Logistic Regression, to Random Survival Forest Summaries of the theory behind each model as well as API descriptions and examples Detailed tutorials on how to perform exploratory data analysis, survival modeling, cross-validation and prediction, for churn modeling and credit risk, for example Performance metrics to assess the models' abilities like c-index or brier score Simple ways to load and save models Installation If you have already installed a working version of gcc, the easiest way to install Pysurvival is using pip. pip install pysurvival The complete installation steps can be found here.

### AI overview

This tutorial examines a blog's unexpectedly high first input delay and explains how to diagnose the cause with performance traces. It introduces the idle until urgent strategy as a way to improve responsiveness without removing site functionality.

### Source excerpt

A few weeks ago I was looking at some of the performance metrics for my site. Specifically, I wanted to see how I was doing on our newest metric, first input delay (FID). My site is just a blog (and doesn't run much JavaScript), so I expected to see pretty good results.

### AI overview

This article describes the new Trace view in Apollo Engine, a GraphQL gateway and successor to Apollo Optics. The updated view helps developers inspect query critical paths, distinguish resolver time from network, queueing, parsing, and validation time, and identify when resolver execution starts and ends.

### Source excerpt

Last week we announced our new GraphQL gateway product and successor to Apollo Optics, Apollo Engine. It has the essential GraphQL monitoring features like request tracing and performance metrics over time that Optics did, and adds new functionality like error reporting and whole query caching.
