The writer is developing an app to handle file ingestion, particularly for Apple's iWork documents (.key, .numbers, .pages). Current solutions require converting these files to PDF or other formats for processing, which often results in loss of information. The author previously succeeded by allowing client-side parsing of file metadata without uploading, suggesting a similar approach for iWork files to retrieve high-quality data directly from the native format. In 2013, Apple changed the iWork document format from XML to a binary format

Alexandre Ruban's article discusses how to use the Showcase feature in a Rails application, specifically focusing on rendering a preview for a button component. Starting from the URL for the button preview, the article guides readers through the code behind this functionality. Initially, it suggests simplifying the preview to show only the title, badges, and description to make understanding easier. The article emphasizes the importance of examining Rails server logs to see the routing to the `Showcase::PreviewsController#show` action, which

The author discusses their experience with microcontroller ADCs, noting that while these are cost-effective and fast, they generally offer poor effective number of bits (ENOB) in practice (about 8 or 9 bits). They have recently been experimenting with the ADS1115, a dedicated ADC from Texas Instruments that claims to provide true 16-bit accuracy. The ADS1115 features a dynamic range capability, allowing for up to 20 times finer measurements of low voltage signals, and its programmable gain

Product market fit is crucial for startups, and while both product and market are vital, the underlying "data model" acts as the binding element between them. The data model represents the key concepts or priorities a startup focuses on, influencing everything from database architecture to user interface design, pricing, and go-to-market strategies. Each startup inherently has a data model, whether explicitly defined or derived from existing models, which can be challenging to alter once established. Typically, innovation in data models is not advisable, as

The author reflects on the challenges of tracking website visitors today, noting that traditional server logs, once useful for analyzing traffic, are now largely ineffective due to the prevalence of bots, especially those from AI companies. While some bots identify themselves through headers, many disguise their true nature. Modern tracking relies on JavaScript, with tools like Google Analytics gaining extensive data from users, leading to concerns about privacy and data collection. The author explores alternatives, such as embedding an invisible image to log visits, but realizes that
