<strong>How Google Maps quietly allocates survival across London's restaurants - and how I built a dashboard to see through it (12 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Google Maps algorithms influence London's restaurant scene as it acts as a “market maker,” using prominence signals that create a cumulative advantage for some restaurants. This was done by scraping data from over 13,000 establishments and building a machine-learning model. To counter this, this dev developed a dashboard that identifies "underrated gems" by calculating the divergence between a restaurant's actual rating and its algorithmically predicted performance.

<strong>How to implement iOS widgets in Expo apps (7 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Despite widgets requiring native Swift code, you can use Expo and the `@bacons/apple-targets` plugin to integrate them together. This setup allows the React Native app and Swift widget to share data via App Groups and deep link back to the main app for expanded features.

Getting a Google Gemini 3 Pro API key in the Google Cloud Console is unintuitive. This is because Google Cloud has many identically named products, a complex billing setup, and an identity verification process.

<strong>What Actually Makes You Senior (4 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
The one core skill that separates senior engineers from everyone else is the ability to reduce ambiguity. Senior engineers ask questions nobody else asks, separate what matters from the noise, and identify what should be done now. They're worth their salaries because they derisk projects. When senior engineers do this well, it looks easy.

Python Workers allow Python developers to ship Python globally in less than two minutes in a single command. Python Workers now supports any package supported by Pyodide, the WebAssembly runtime that powers Python Workers. It also now has dedicated memory snapshots to reduce cold start times.

A survey by Stack Overflow explored developer frustrations amidst increasing AI adoption, finding that 84% currently use or plan to use AI, mainly for coding, searching, and debugging. However, developer problems aren't mainly from coding tasks themselves or AI's shortcomings, but rather from a lack of adequate and accessible documentation. Tasks like learning new codebases, deployments, and handling support tickets become frustrating due to fragmented and bad documentation efforts.
