Don't Use SQLite in Production!

Terreateam shares their experiences using Fly.io and SQLite. While Fly.io heavily promotes server-side SQLite, the author argues against using it as a primary data store in production unless there's a compelling reason. This adds complexity with backups, high availability configurations (like LiteFS and Consul), and migration to other databases (like PostgreSQL) becomes challenging. The post uses the Atlantis project as an example, highlighting the high-availability challenges of using database-as-a-library solutions (like BoltDB and SQLite), ultimately recommending a traditional database architecture for production unless there's a very clear need to diverge for better scalability and reliability.

Iodized Salt and the Unexpected IQ Boost

2025-01-29

Iodized Salt and the Unexpected IQ Boost

New research reveals that adding iodine to salt in the US since 1924 significantly boosted cognitive abilities across the American population throughout the 20th century. Initially implemented to reduce goiter, studies now show iodine's crucial role in brain development. By comparing military enlistment data from before and after 1924, researchers found a 15-point IQ increase in low-iodine areas. While early iodine supplementation caused some thyroid-related deaths, the initiative virtually eradicated iodine deficiency and its consequences. This discovery may also partially explain the Flynn Effect – the observed rise in IQ scores throughout the 20th century – suggesting iodine contributed to a significant portion of this increase.

Netflix's Deep Downscaler: A Critical Look

2025-03-01

Netflix recently published a blog post about their "deep downscaler," claiming it uses neural networks to improve video quality. However, a blogger has sharply criticized the technology. The blogger points out severe flaws in the example image provided by Netflix, including ringing artifacts, bizarre color shifts, and seemingly fake "detail." Furthermore, the training process minimizes mean squared error while ignoring the effects of lossy compression, leading to suboptimal results. The blogger argues that Netflix's deep downscaler suffers from over-reliance on metrics while neglecting crucial human visual assessment and that simpler, more efficient solutions exist.

GM Forces Dealer to Halt Aftermarket CarPlay/Android Auto Kit for Ultium EVs

General Motors (GM) forced a dealer to discontinue an aftermarket kit that restored Apple CarPlay and Android Auto phone mirroring in its Ultium electric vehicles. This follows GM's decision in December 2023 to remove CarPlay and Android Auto support from Ultium EVs, opting for its own in-vehicle infotainment systems in future models. While the kit's manufacturer, WAMS, claims rigorous testing, GM's action sparked industry criticism, as a study showed nearly half of car buyers wouldn't purchase vehicles lacking CarPlay or Android Auto. GM is effectively pushing dealers towards its built-in systems, leaving little alternative.

Terraform Docker Provider: Handling Image Attribute Changes Gracefully

2025-03-27

When managing Docker containers with Terraform, the Docker provider transforms the `image` attribute into a SHA digest. This leads to subsequent Terraform refreshes incorrectly detecting image changes and forcing container rebuilds. Simply using `lifecycle { ignore_changes = [image] }` masks actual image changes, creating a potential risk. This article presents a solution: leverage a `null_resource` as a trigger. When the `image` attribute changes, the `null_resource` rebuilds, indirectly triggering a container rebuild, ensuring image updates while avoiding unnecessary container recreation.

Svelte 5 Migration: Performance Gains, Cognitive Overhead

Upgrading a web application to Svelte 5 led to unexpected issues. Svelte 5's performance improvements, driven by "deep reactivity," introduce proxies and implicit component lifecycle state. While seemingly simpler, this adds abstractions, requiring developers to manage complex heuristics. Proxies aren't objects, and components aren't functions. The author details problems with proxies and callbacks, such as `DataCloneError` and props becoming undefined after component unmounting. Svelte 5 sacrifices developer agency, increasing cognitive load, leading the author to abandon it for new projects. The conclusion emphasizes choosing tools that leverage existing knowledge and promote understanding over cleverness.

From SQL Server to Key-Value Stores: A Postmortem of a Database Rewrite Gone Wrong

2025-06-15

A senior developer recounts their experience with a database rewrite at a previous company. The original system, using SQL Server, suffered from performance bottlenecks and frequent outages due to complex stored procedures. The rewrite opted for simple key-value stores, but due to data model mismatch and lack of transaction support, I/O operations skyrocketed, performance worsened, and a complex checkpointing system was introduced. The rewrite ultimately failed to solve the original problems and created new challenges. This humorous account reflects on the importance of technology selection and architectural design, and the negative impact of oversimplification.
