YOU CAN CHOOSE TOOLS THAT MAKE YOU HAPPY

People often choose obscure or outdated technologies for emotional reasons, like feeling connected to a certain tradition or aligning with specific aesthetics. They then create rationalizations for these choices, downplaying the downsides of their preferred tech and exaggerating the drawbacks of popular alternatives. However, it's perfectly fine to use tools that bring you joy without any need for justification.

GOOD WRITING

Good writing is both aesthetically pleasing and conceptually accurate, and these qualities are surprisingly interconnected. Polishing the sound of writing often clarifies and refines the ideas themselves, similar to how shaking a bin helps objects pack together efficiently. This is because making writing sound good forces the writer to confront and resolve inconsistencies or awkwardness in their thinking.

AT AMAZON, SOME CODERS SAY THEIR JOBS HAVE BEGUN TO RESEMBLE WAREHOUSE WORK

Amazon software devs are being pushed to use AI, leading to a faster pace and higher output goals. Some engineers feel like they are "bystanders" in their own jobs, as the focus has shifted from writing code to reviewing AI-generated code, which reduces the time for reflection and collaboration. While companies like Amazon argue AI can relieve tedious tasks, some workers worry about the impact on career advancement and the degradation of work quality.

EXCLUSIVE LOOK AT THE CREATION OF HIGH NA, ASML'S NEW $400 MILLION CHIPMAKING COLOSSUS

High NA, which stands for high numerical aperture, is the world's most advanced and expensive chipmaking machine. Costing more than $400 million, the machine took ASML nearly a decade to develop. It is made up of four modules that are manufactured around the world and assembled in the Netherlands. Only five of the colossal machines have ever been shipped. This article takes a look at High NA, how ASML plans to deploy the technology, the benefits that High NA provides, how the technology works, the effects that China, tariffs, and US growth will have on the technology, and more. A link to a video showing High NA in action is available at the end of the article.

WORLD'S TALLEST 3D-PRINTED BUILDING REACHES A HEIGHT OF 100 FEET

The Tor Alva, the world's tallest 3D-printed building, has been completed in Switzerland. The structure, which the creators liken to an 'ornate layered cake', sits at an impressive height of 30 meters. It is located in a village that's currently home to just 11 people. The building took around 900 hours of printing to complete using two construction robots: a 3D printer and a machine used to add steel reinforcement. Pictures of Tor Alva are available in the article.

The company is likely in the top 1% in software delivery performance. It has a very demanding but advanced engineering culture with a relentless focus on continuously shipping value for users. Shipping safely at this velocity and scale implies heavy investment in automated tests, deployments, rollbacks, observability, code ownership, and other areas.

ENGINEERS AND AI: RAMBLINGS OF A SMALL STARTUP FOUNDER

While everyone seems to want to replace software engineers, AI just isn't there yet. Not everyone can just dive into a problem with little context and get started - it takes time to understand the problem and ask relevant questions to determine requirements. There is value in being able to say 'I don't know how to do this', but this is less and less likely to happen now that people are falling back to AI for answers when all else fails. People learn by doing something hard - struggle is part of improvement.

ANTHROPIC CLAUDE 4 MODELS A LITTLE MORE WILLING THAN BEFORE TO BLACKMAIL SOME USERS

Anthropic's new Claude models are more willing than prior models to take initiative on their own in agentic contexts. This can show up as more actively helpful behavior in ordinary coding settings, but it can cause the model to act concerningly when prompted with strong moral imperatives. This can include locking users out of systems or bulk-emailing media and law-enforcement figures to inform them of wrongdoing. The behavior only shows up in testing environments where the model is given unusually free access to tools and very unusual instructions.
