AI Inference Costs: Not as Expensive as You Think

This article challenges the narrative that AI inference is prohibitively expensive and unsustainable. By calculating the costs of running AI inference on H100 GPUs, the author demonstrates that input processing is incredibly cheap (fractions of a cent per million tokens), while output generation is significantly more expensive (dollars per million tokens). This cost asymmetry explains the profitability of some applications (like coding assistants) and the high cost of others (like video generation). The author argues that this cost disparity is often overlooked, leading to an overestimation of AI inference costs, which may benefit incumbents and stifle competition and innovation.

The Clever Design and Shortcomings of C++'s std::adjacent_difference

2025-08-25

This article delves into the design philosophy of the `std::adjacent_difference` algorithm in the C++ standard library. This algorithm computes the differences between adjacent elements of an input sequence, copying the first element to the output. While this design ensures symmetry with `std::partial_sum`, mirroring differentiation and integration in calculus, it also limits its genericity, as the difference between elements of an arbitrary type might have a different type. The article further draws parallels to derivatives and integrals in calculus, explaining the algorithm's design rationale and contrasting it with Q's more flexible `deltas` function. The conclusion is that, while Stepanov's original intent was sound, the algorithm lacks genericity; C++23's `pairwise_transform` offers a more flexible alternative.

Claude Code: My AI-Powered Terminal Assistant Saves Me an Hour a Day

For two months, I've run Claude Code in "dangerously-skip-permissions" mode on macOS, bypassing all permission prompts. While risky (I use robust backups), it's saved me about an hour daily. Claude Code isn't just a smarter command line; it's a universal computer interface. I use it for everything from migrating Macs and converting blog posts to generating test data, managing Git, and automating system tasks. Its command-line-first design and ability to understand context make it highly efficient, though response time can be a limitation. Unlike Warp, Claude's "dangerous mode" allows for continuous workflow without constant permission requests. This represents a paradigm shift in developer tools – from command execution to intent understanding and action. It's not about AI replacing developers, but about developers becoming orchestrators of powerful systems.

The UK's Electrifying History: From Chaos to Nationalization and Back

The UK's Electrifying History: From Chaos to Nationalization and Back

This article chronicles the evolution of the UK's electricity system from its chaotic beginnings in the late 19th century to its current state. Initially, local electricity companies operated independently, resulting in inconsistent voltage and frequency, and low efficiency. World War I exposed the criticality of this fragmented system, leading to government-driven efforts toward regional interconnection. Despite the 1919 Electricity (Supply) Act, progress was slow due to local protectionism and the lack of enforcement power. A 1925 inquiry highlighted the severity of the situation, paving the way for a large-scale national grid. After World War II, the grid was nationalized, only to be privatized under Margaret Thatcher's government, leading to ongoing debate. The article uses the UK's century-long electricity journey as a case study to explore the influence of government regulation, market competition, and technological advancements on energy systems.

JavaScript Date Object UTC Trap: Missing Data in Japan

2025-07-30

A seemingly simple JavaScript date filter caused the loss of backend data for Japanese users before 9 AM. The reason? `new Date('YYYY-MM-DD')` creates a date object at midnight UTC, which is 9 AM in Japan (UTC+9). Therefore, 'greater than January 1st' actually meant 'greater than 9 AM on January 1st'. The fix involved explicitly setting the time to midnight to avoid the UTC default.
