The 1875 COBOL Date Myth: Efficient Data Structures, Not a Language Flaw

The 1875 COBOL Date Myth: Efficient Data Structures, Not a Language Flaw

The widespread rumor that COBOL systems default to May 20, 1875, for missing dates is false. This article reveals that the origin lies in the extreme optimization of data storage in early systems. To save storage space, programmers cleverly used data structures, taking 1875 as the base year and encoding dates into fewer characters. This approach was efficient and reasonable in the resource-constrained environment of the time, not a flaw of COBOL but a clever use of data structures by programmers.

Discord Ads: High CPMs, But Still Experimental

Discord's ad products currently use a fixed pricing model based on projected reach, frequency, brand lift, and user engagement. Premium inventory CPMs range from roughly $25 to $30, varying by format, region, and reach. Discord uses CPM pricing instead of CPA because both views and engagement provide value, and it's the right economic model for them, competitively positioned within the premium tier but below the highest-priced platforms. While advertising holds promise, it remains a relatively experimental business unit for Discord in 2025; most revenue comes from its Discord Nitro subscription service.

Pastured vs. Industrial Poultry: A Bird Flu Showdown

Despite sophisticated biosecurity measures, industrial poultry farms continue to struggle with avian flu outbreaks. The virus can enter even high-tech barns through ventilation systems. Smaller, pasture-raised farms, while seemingly at higher risk due to increased contact with wild birds, report fewer outbreaks. This is attributed to healthier birds with stronger immune systems due to better diets and outdoor access. Experts debate the feasibility of pasture-raised poultry meeting market demands and whether the increased contact with wild birds outweighs the health benefits.

cURL and Go Security Teams Reject Flawed CVSS Scoring System

cURL and Go Security Teams Reject Flawed CVSS Scoring System

The cURL and Go security teams have publicly denounced the Common Vulnerability Scoring System (CVSS) as flawed for assessing vulnerabilities, advocating for more accurate, context-aware approaches. CVSS's one-size-fits-all approach often leads to misleading scores, especially for projects like cURL with billions of installations. Daniel Stenberg, cURL's creator, highlighted CVSS's failure to account for specific contexts, resulting in inflated or inaccurate scores. The Go security team echoed these sentiments, opting for context-driven severity assessments instead. This highlights growing dissatisfaction with CVSS and pushes for better alternatives. However, this context-driven approach faces challenges, as maintainers struggle to accurately gauge all user scenarios. A culture clash between security researchers and open-source maintainers further complicates the issue, with researchers seeking recognition and maintainers focusing on practical impact. The NVD's backlog problem exacerbates the situation.

Basel Tax Authority Buys Bahamian Web Address Due to Flyer Error

The Basel-Stadt tax authority had to purchase a web address in the Bahamas due to a mistake on an information flyer for digital tax returns. The flyer, sent to over 100,000 households, omitted the '.ch' from the web address, redirecting users to a '.bs' domain in the Bahamas. While the error has been addressed and the Bahamian address will redirect to the correct Swiss site, the mistake cost the authority CHF 900, significantly cheaper than the estimated CHF 100,000 to reprint the flyers. Taxpayers can still file their returns online, albeit with a brief Caribbean detour.

Exoplanet Tylos: A Lava Planet Defying Our Understanding of Weather

Astronomers using the European Southern Observatory's Very Large Telescope have conducted in-depth research on an exoplanet named Tylos (WASP-121b). Located 900 light-years from Earth, this planet has a 30-hour orbital period, with one side perpetually scorching and the other perpetually dark. By analyzing its atmospheric iron, sodium, and hydrogen elements, researchers discovered an unprecedented phenomenon: a high-speed jet stream at the equator, alongside a lower atmospheric flow transporting gas from the hot side to the cold side. This bizarre climate pattern challenges our understanding of planetary weather systems and reads like something out of science fiction.
