Tesla's Shanghai Gigafactory Rumored to Produce a Budget Model Y 'E80'

Rumors suggest Tesla's Giga Shanghai will produce a more affordable Model Y variant, internally codenamed 'E80', this May. This stripped-down version is expected to feature smaller wheels, single-layer side windows, no rear display, fewer speakers, single-color ambient lighting, fabric seats without heating or ventilation, and a manual trunk. These reductions aim to bring the price down to ¥190,000-¥210,000 ($26,000-$28,800), potentially even lower to ¥150,000-¥170,000 ($20,500-$23,300). This strategy mirrors Tesla's previous releases of budget-friendly variants of the Model 3 in Mexico and the Cybertruck in the US, both featuring cost-cutting measures like textile seats and reduced features. Despite the cutbacks, the 'E80' is anticipated to remain attractive due to the Model Y's premium branding and the competitive Chinese EV market.

TrailBase: A Blazing Fast Lightweight Database

2025-02-04

TrailBase, a lightweight database, combines a low-overhead language, a fast HTTP server, and a lightweight relational SQL database. Benchmarks show TrailBase inserting 100k records over 20 times faster than SupaBase, 10 times faster than PocketBase, and even slightly faster than in-process vanilla SQLite. While SupaBase offers more features, its memory footprint is roughly 50 times larger than TrailBase's. TrailBase boasts sub-millisecond read latencies, comparable to Redis, but operates on primary data, not a cache. Its JavaScript performance is also exceptional, with its V8 engine outperforming PocketBase's goja engine by a factor of 40. In short, TrailBase is incredibly fast and resource-efficient, but real-world testing is crucial.
