KDE Plasma: A Surprisingly Delightful Linux Desktop Experience

2025-09-18

The author recently switched their gaming rig's desktop environment to KDE Plasma, initially for their wife's convenience. However, they were pleasantly surprised by its comprehensive features and impressive speed. KDE Plasma's network applet provides extensive network information; its integrated screenshot tool is powerful; and its window rules in System Settings allow for extensive customization of application windows. Furthermore, KDE Plasma boasts many pre-integrated tools, such as Flatpak permission configuration, hardware information viewing, and sleep prevention—features that typically require separate software installations on Windows and macOS. While encountering minor initial issues, the author ultimately found KDE Plasma a highly satisfying experience, calling it the best Linux desktop environment they've used in years.

Gmail Accused of Partisan Spam Filtering: GOP Claims Bias

FTC Chairman Andrew Ferguson accused Google of using partisan spam filters in Gmail, allegedly sending Republican fundraising emails to spam while delivering Democratic emails to inboxes. Ferguson's letter to Alphabet CEO Sundar Pichai alleges potential FTC Act violations. Google denies the accusations, stating its spam filters are based on objective user signals and apply equally to all senders, regardless of political affiliation. This reignites long-standing Republican complaints previously dismissed by a federal judge and the Federal Election Commission.

macOS Tahoe's ASIF Disk Images: A Performance Leap

macOS Tahoe introduces ASIF, a new disk image format that dramatically improves virtual machine performance. ASIF images are independent of the host filesystem's capabilities, achieving near-native speeds; for example, on an M3 Pro MacBook Pro, unencrypted APFS volumes reached 5.8 GB/s read and 6.6 GB/s write. ASIF offers a massive speed advantage over previous UDSP images and saves disk space. Currently, ASIF images can only be created in Tahoe, but they work in Sequoia. Future virtualization software is expected to support ASIF, further enhancing VM performance.

Cuttle: A Retro Two-Player Card Game That's More Than Just Luck

2025-01-10

Cuttle, a two-player card game emerging in the 1970s, challenges players to reach 21 points first using a standard 52-card deck. Gameplay involves strategic card placement and unpredictable effects. Players deploy point cards to score or 'scuttle' opponent's cards, while one-off and permanent effect cards introduce twists and turns. Aces clear the board, twos counter effects, and kings reduce the winning point requirement. With its blend of strategy and chance, Cuttle offers a unique and engaging retro gaming experience.

Irish Minister Rejects Streaming Levy: Consumers Price Out

Ireland's Minister for Media, Patrick O'Donovan, has opposed proposals for a levy on streaming services like Netflix, arguing it would price consumers out of entertainment. Despite previous preparations for the levy, intended to fund domestic programming as recommended by the Media Commission, O'Donovan will bring a memo to Cabinet opposing it. He believes the existing television license fee suffices for terrestrial television and plans to address legal loopholes via the Broadcasting Bill. Concerns over RTÉ funding also feature, with O'Donovan highlighting an almost 'monopolistic' situation regarding license fees, advertising, and Sound and Vision funding, and pushing for increased accountability.

AI Benchmarking Scandal: Did Big Tech Rig Chatbot Arena?

AI Benchmarking Scandal: Did Big Tech Rig Chatbot Arena?

A new paper from Cohere, Stanford, MIT, and Ai2 accuses LM Arena, the organization behind the popular Chatbot Arena benchmark, of unfairly favoring top AI companies like Meta, OpenAI, Google, and Amazon. The researchers allege that these companies were allowed to privately test multiple model variants, suppressing poor-performing results to boost their leaderboard rankings. Analyzing over 2.8 million battles, the study found evidence of increased sampling rates giving these companies an unfair advantage. LM Arena disputes the findings, citing inaccuracies, and plans to improve its sampling algorithm, but denies manipulating rankings. The controversy raises concerns about fairness and transparency in AI benchmarking and highlights the competitive tactics employed by large tech companies in the AI race.

German UBI Experiment: Full-Time Work Continues, Happiness Increases

A three-year German experiment provided 122 participants with a monthly unconditional basic income of €1,200. Surprisingly, participants didn't reduce their working hours; instead, job satisfaction increased, and they were more likely to change jobs or pursue further education. The study showed that unconditional basic income didn't decrease economic activity but improved participants' mental and physical health, particularly for women, who experienced a greater sense of autonomy. This experiment challenges the conventional wisdom that basic income discourages work and offers valuable insights for future policy decisions.

C++ Template Inheritance and Copy Construction: A Puzzling static_assert

C++ Template Inheritance and Copy Construction: A Puzzling static_assert

This article explores a puzzling issue regarding copy constructors in C++ template inheritance. The `Derived` class inherits from `Base`, where `Base`'s copy constructor is deleted. However, `Derived` defines its own copy constructor. Even though this constructor attempts to copy the uncopyable `Base` object, `std::is_copy_constructible` still returns true. This is because the compiler only checks for the presence of a non-deleted copy constructor, not its instantiability. The author further discusses the differences between explicitly defined and implicitly defined copy constructors, and the implications of moving the copy constructor definition out of line.

Dissecting Canon's STM Lens Stepper Motor

2025-03-10

Canon's STM lenses utilize a unique 2-phase bipolar stepper motor with a permanent magnet rotor and a rotationally symmetrical stator, unlike the AFD stepper motor. The article first explains the general working principle of a stepper motor, then delves into the specifics of Canon's STM motor design. The motor uses two independent coils, energized in both directions to create varying magnetic polarities, driving rotor rotation. Full-step and half-step modes are briefly mentioned, but half-step mode isn't explored further due to autofocus systems prioritizing speed over precision.

Dieppe Raid: A Costly Failure?

This account recounts the disastrous Dieppe Raid of 1942. Over 5000 Allied soldiers participated, suffering heavy casualties with at least 2000 killed or captured. While the RAF inflicted significant damage on German fighters, the raid itself was a failure, achieving minimal strategic objectives and resulting in substantial Allied losses. The text explores potential reasons for the failure, including German advance knowledge and deficiencies in Allied fire support and landing plans. The debacle underscored the immense challenges of a European invasion and provided crucial lessons for future amphibious operations.

During Queen Victoria's reign, London's cat's meat men, with their blue aprons, black hats, and corduroy trousers, became a subject of anthropological investigation by journalists.
