html2canvas Fails on Tailwind CSS v4 oklch() Colors; Forks Offer Fixes

·2 views

Calling html2canvas on pages styled with Tailwind CSS v4 can throw an 'unsupported color function' error because the library's parser does not recognize modern functions like oklch(). The issue stems from the official html2canvas 1.4.1 release predating these CSS color spaces, not from Tailwind itself. Two maintained alternatives are suggested: html2canvas-pro, a modern fork that supports these colors, and html2canvas-lts, a drop-in fork that adds parsing for them. Developers who must keep the official package can instead rewrite the captured elements' colors to rgb() or hex before rendering, though this is more laborious. The article credits the original library's author and notes that the forks are separate projects.

Supabase 'infinite recursion' error from circular RLS policies, and how to fix it

A common Supabase problem appears when adding sharing, teams, or admin roles: pages that previously loaded return an 'infinite recursion detected in policy' error with code 42P17. The cause is row-level security policies that query the same table they protect, or two tables whose policies reference each other, forcing PostgreSQL into an endless evaluation loop. The author tested this against PostgreSQL 16.15 and notes the error can name the wrong table and may not reproduce in the SQL Editor, which bypasses policies for the table owner. The recommended fix is moving the lookup logic into a SECURITY DEFINER function in a private schema, which runs with privileges that skip the recursive policy check. Example functions and rewritten policies are provided for both the single-table admin case and the two-table sharing case.

Power BI Dashboards Help Sports Teams Turn Athlete Data Into Training Decisions

Sports teams, coaches, and fitness professionals are increasingly using analytics to assess athletes and refine training strategies. Every session and competition produces data on speed, stamina, workload, and recovery, which is hard to analyse manually. Microsoft Power BI can convert this raw information into interactive dashboards that reveal performance patterns. Such dashboards can track progress over time, monitor workload and injury history, and track health and recovery indicators. Experts note that these tools support monitoring and analysis, while medical diagnoses and return-to-play decisions remain the responsibility of qualified healthcare professionals.

Building a Safe Expression Parser to Replace eval Under a Strict CSP

A developer building a live graphing calculator could not use eval because the site's Content-Security-Policy forbids unsafe-eval, a restriction that also shields the site from XSS via user input. Instead, they wrote a roughly eighty-line expression parser that runs in four stages: tokenizing, inserting implicit multiplication, converting to reverse Polish notation via the shunting-yard method, and evaluating. The article highlights three common pitfalls: treating unary minus as ordinary subtraction (so -3^2 must equal -9), requiring right-associativity for exponentiation (so 2^3^2 equals 512), and recognizing implicit multiplication such as 2x without mistaking function names like sin(x) for variables. Parsing once and evaluating the compiled expression at each sample point keeps the plotting loop fast.

Cómo medir si un proceso mejoró de verdad, con cuatro indicadores clave

Un proceso solo puede considerarse mejorado si un indicador definido antes del cambio se mueve en la dirección esperada, sin que otros empeoren, y si ese resultado se mantiene con el tiempo. El artículo recomienda cuatro métricas para pymes: tiempo de ciclo, medido con la mediana y el percentil 90; retrabajo o errores como porcentaje de casos; pasos manuales por caso; y costo por transacción. Advierte que sin una línea base registrada, la supuesta mejora es solo una impresión del equipo. También señala que instalar una herramienta o recibir buenas opiniones no equivale a un resultado. Por último, subraya la importancia de contemplar el volumen de trabajo para interpretar correctamente cualquier variación.
