4. So thieves broke into your storage unit again
Total comment counts : 27
Summary
The article reflects on the experiences of a classic computer collector who, like many collectors, has accumulated more hardware than they can store at home, necessitating the use of storage units. The author details the use of both climate-controlled and conventional storage units in southern California and shares personal experiences related to burglaries at these facilities.
The first incident occurred nearly two decades ago, revealing the poor security of the storage unit. Intruders easily accessed the climate-controlled area by removing hinge pins, bypassing the lock entirely. Items stolen included a family VHS camera, a digital camera with irreplaceable photos, a Fisher-Price video camera, and a spare Mattel Intellivision. Some items were later recovered, but the process highlighted issues with storage unit security and the inadequacies of the insurance provided by the rental chain, which benefited from kickbacks and offered limited protection.
The article ends with a cautionary note on the risks of using storage units without adequate security and the importance of being prepared with personal insurance, especially for valuable items.
Top 1 Comment Summary
The article critiques the storage unit industry, highlighting its customer-unfriendly nature, including difficulties in reaching local facilities and inaccurate pricing from call centers. It reveals security flaws, noting that many units can be easily broken into due to poor padlock quality, alongside issues like rodent infestations. The author points out a financial paradox where the monthly cost of a storage unit can exceed the value of the stored items, particularly if they lack sentimental or high monetary value. Citing a specific example, it mentions that a company’s losses from theft were surpassed by rental payments within two years, echoing the average storage unit tenancy of only 10 months, suggesting long-term storage rarely makes financial sense given the security concerns.

7. When Earth Had Rings
Total comment counts : 6
Summary
The article discusses a new study suggesting that Earth may have once had its own ring system, akin to those found around Saturn, Jupiter, Uranus, and Neptune. This idea arises from a period about 466 million years ago, during the mid-Ordovician, characterized by a spike in meteorite impacts that left 21 major craters. Researchers from Monash University, led by geoscientist Andy Tomkins, argue that these impacts could be explained if Earth had captured rings from an asteroid.
The study examined the distribution of these impact craters and discovered that they were concentrated around the equator. By using computer models to reconstruct continental movements over millions of years, they concluded that the likelihood of such an even distribution of impacts occurring randomly was extremely low (1 in 25 million). They propose that these impacts resulted from objects within a ring system that Earth once possessed. Similar tidal disruption events have been observed when large objects pass too close to planets, causing fragments to be captured into orbit. This hypothesis opens new avenues for understanding Earth’s geological history.
Top 1 Comment Summary
The author expresses frustration that an article about Earth 466 million years ago features a modern image of Earth with rings, rather than accurately depicting its ancient surface. While the article includes a map, it lacks an artistic representation. Most other sources have also used similar ringed artwork, although one source provides an artist’s rendition to better reflect the topic.

Summary
The article introduces Brisa, a framework designed for building web applications with a focus on speed and simplicity. Brisa’s pages are server-rendered JSX components, meaning no JavaScript is shipped to the browser by default. It operates primarily on the server, while the web components are managed on the client side.
Key features include:
- Handling browser events (like forms and clicks) on the server.
- Built-in internationalization (i18n) support for translations.
- Capability to convert web applications into native apps for Android, iOS, and desktop through integration with Tauri.
- The option to create single-page applications (SPAs) or multi-page applications (MPAs) without necessarily using Web Components.
Brisa seeks to unify server and client development using the Web Platform, facilitating high performance while minimizing client-side load. The framework aims to empower developers with a streamlined experience, contribute to an open-source community, and encourage community involvement. Users are invited to engage through documentation, a newsletter, and an upcoming Open-Collective initiative.
