1. Hidden interface controls that affect usability
Total comment counts : 67
Summary
Douglas Engelbart introduced the concept of “knowledge in the world” versus “knowledge in the head” in interface design, later popularized by Donald Norman. Knowledge in the world means controls are visible and easily identified, as seen in drop-down menus, enabling users to perform tasks without memorization. However, we are increasingly reverting to designs requiring significant knowledge in the head, especially with modern devices like smartphones. These often have hidden controls that complicate simple tasks, underscoring the need for visible controls to improve user experience and accessibility.

The article argues that tech companies like Google, Apple, and Microsoft intentionally obscure user interface features to create user lock-in once their software reaches saturation, prioritizing retention over new users. This strategy alters users’ perceptions, making them feel deeply connected to the devices, thus deterring them from switching to alternatives. Users adapt to hidden functionalities, leading to anxiety when considering a new system. This tactic is prevalent among major software developers to maintain their user base.

Top 1 Comment Summary
The Lisa’s canvas is scaled to 1.5 times its width, leading to distortion on low-resolution displays but generally appearing fine on high-dpi screens. Larger low-dpi displays can utilize automatic integer scaling by resizing the window, adjustable in the preferences app. A reset of scaling settings can be performed by restarting LisaGUI while holding the shift key. Additionally, iOS users may encounter minor bugs with PWAs regarding canvas positioning, which can be fixed by changing device orientation. To close windows, double-click the icon in the titlebar to collapse it back to an icon.
Top 2 Comment Summary
Many users have noted uneven character widths in the font, which is a bitmap design consistent in its style. The Lisa’s font features wider vertical strokes to address the pixel aspect ratio. Perceived unevenness may arise from viewing on low-DPI displays at 1x scale. Users are encouraged to send screenshots for debugging via a provided email or messaging on Bluesky. Project updates are posted regularly on Bluesky and an RSS feed is available on the website for those preferring traditional updates.

Summary
The article discusses the unique use of DNS LOC records, which can specify the geographical location (latitude, longitude, and altitude) of servers. It highlights a fun application: a DNS record that provides the location of the International Space Station (ISS) via the domain where-is-the-iss.dedyn.io. The record updates every 15 minutes, leveraging data from an API provided by N2YO. The author mentions challenges in updating LOC records and notes the limitations of Windows tools to access this type of DNS record, while playfully contemplating how to represent coordinates for other space objects.

The article discusses concerns regarding API limitations, questioning whether a 15-minute delay is excessive for tracking an object that completes an orbit around Earth in 90 minutes. The author notes that this delay translates to an estimated positioning error of about a twelfth of the Earth’s circumference, equating to the distance between Lisbon and Istanbul.
4. Serving 200M requests per day with a CGI-bin
Total comment counts : 24
Summary
Jake Gold explores the viability of 90s CGI technology by running a Go + SQLite CGI program on modern hardware. Despite CGI’s inefficiencies due to process overhead for each request, advancements in CPU power and languages like Go and Rust make it feasible to serve over 200 million requests daily. This new execution model allows better use of multi-core processors. Gold suggests that while CGI isn’t a mainstream choice today, it’s interesting to reconsider its potential with today’s technology, advocating for a blend of past methods and contemporary programming practices.
Top 1 Comment Summary
CGI scripts can efficiently handle high traffic, serving up to 160 requests per second on a server with 64 cores. For sites handling millions of requests daily, CGI startup time isn’t the bottleneck. However, there are concerns as Python maintainers remove stable, longstanding modules like the cgi module in version 3.13, citing a desire for innovation over stability. The author, experienced with Python for 25 years, now feels uncertain and is considering alternatives like JavaScript or Lua for prototyping.
Top 2 Comment Summary
The author tested a $350 mini server running a Go binary, RabbitMQ, Redis, and MySQL, successfully managing 5,000 requests per second, amounting to 400 million requests daily. They expressed their amazement at the efficiency of free tools available today, contrasting it with the high costs of cloud services. While acknowledging the differences in comparison, they appreciated the ability to develop and optimize their setup from home.

The user transitioned from using AI tools in Zed to a terminal-based agent, OpenCode, which greatly impressed them. They appreciated the efficient feedback loops that allowed OpenCode to write tests, run the test suite, and address errors autonomously—features not present in Zed. This experience gave them a newfound ability to step away from their laptop and return to significant progress on their work, resulting in overall satisfaction.
10. A non-anthropomorphized view of LLMs
Total comment counts : 55
Summary
The blog discusses the complexities of “alignment” and “AI safety,” challenging the tendency to attribute human-like qualities to AI, which the author views as fundamentally rooted in mathematical operations. The author acknowledges a critique of this perspective, comparing AI to the brain’s biochemical processes, and feels a need to elaborate on the argument’s nuances.
Top 1 Comment Summary
The author argues that while they understand the technical workings of large language models (LLMs), using overly technical language is ineffective for discussing their capabilities, such as answering complex questions or storytelling. They advocate for a higher abstraction level, akin to how user interfaces are discussed, as current understanding of LLMs at that level is limited. Since LLMs often mimic human output, anthropomorphizing them becomes a useful framework for discussing their potential and functionality.
Top 2 Comment Summary
The article critiques the simplification of large language models (LLMs) as mere sequence generators, arguing that they possess hidden states influencing outputs, which can contradict produced tokens for longer-term goals. While likening this behavior to human-like agency may seem anthropomorphic, it suggests that alternative terminology is necessary to accurately describe these processes. Ultimately, the author advocates for using human-related concepts to classify LLM behavior, despite their imperfect nature, as a way to reduce jargon and clarify understanding.
