Developer Builds Free Fitness Calculator Suite Using Astro for Speed and SEO

0
·2 views

A developer has released Free TDEE Calculator, a collection of fitness tools covering TDEE, BMR, macronutrients, and calorie deficit, built with the Astro framework and hosted on Cloudflare. The site is largely pre-rendered static HTML, with only small client-side scripts for input handling, which keeps pages fast and easy for search engines to read. All calculators draw on a shared formula module, using the Mifflin-St Jeor equation for BMR and an activity multiplier to derive TDEE. Each tool page is paired with a guide that explains the formulas, includes worked examples, and adds FAQ markup to support search rankings. The developer presents the project as an example of how static-first frameworks can deliver both strong SEO and interactive functionality.

The developer published the explanation on their personal website, po-ru.com, dated October 18, 2026. Archiving the repositories makes them read-only, so existing code remains available but no further updates are expected from the author.

Laminar launches flow-1, a low-cost model that detects silent failures in AI agent traces

Laminar, a Y Combinator S24 company building open-source observability tools for AI agents, has released flow-1, a model trained with reinforcement learning to find errors in agent traces. On the company's benchmark, flow-1 reportedly matches the detection quality of GPT-6-sol while costing about 23 times less, making it practical to analyze every production trace rather than sampling. The tool, called Signals, treats each trace as a repository and lets users define custom prompts and output schemas to flag issues such as silent failures or user frustration. Similar findings are grouped into clusters so teams can track recurring problems and build evaluation datasets for fixes. Laminar is released under the Apache 2.0 license, can be self-hosted, and generates revenue from its managed cloud service.

Why sharding and partitioning are key scaling questions in system design interviews

Database sharding comes up in nearly every system design interview once a single database can no longer handle the data volume or write load. Adding read replicas only increases read capacity, leaving write throughput and storage limits unchanged, so horizontal splitting of data across machines becomes necessary. The shard key determines the quality of the design, and candidates must justify it against read and write patterns while naming trade-offs. Interviewers evaluate problem solving, communication, technical execution, and time management, not just whether the word sharding is mentioned.
