Scientists Say They've Created a New Form of Life More Perfect Than the One Nature Made

We've heard of GMOs, but this is ridiculous. Scientists at the Medical Research Council's Laboratory of Molecular Biology say they've engineered a bacteria whose genetic code is more efficient than any other lifeform on Earth. They call their creation "Syn57," a bioengineered strain of E. coli — yes, the same bad boy that can make you extremely sick if you eat an undercooked hot dog — which uses seven less codons than all life on earth. A codon, put simply, is a three-letter sequence found in

How to Fix Your Context

Mitigating & Avoiding Context Failures Following up on our earlier post, “How Long Contexts Fail”, let’s run through the ways we can mitigate or avoid these failures entirely. But before we do, let’s briefly recap some of the ways long contexts can fail: Context Poisoning: When a hallucination or other error makes it into the context, where it is repeatedly referenced. When a hallucination or other error makes it into the context, where it is repeatedly referenced. Context Distraction: When

The oldest unopened bottle of wine in the world

Image by Immanuel Giel, via Wiki­me­dia Com­mons It’s an old TV and movie trope: the man of wealth and taste, often but not always a supervil­lain, offers his dis­tin­guished guest a bot­tle of wine, his finest, an ancient vin­tage from one of the most ven­er­a­ble vine­yards. We might fol­low the motif back at least to Edgar Allan Poe, whose “Cask of Amon­til­la­do” puts an espe­cial­ly devi­ous spin on the trea­sured bottle’s sin­is­ter con­no­ta­tions.

How to build a coding agent

If you would like for me to run a workshop similar to this at your employer, please get in contact Hey everyone, I'm here today to teach you how to build a coding agent.

Writing with LLM is not a shame

Writing with LLM is not a shame. An essay about transparency on AI use. tl;dr: For people who are curious about AI, you rapidly detect people who are using it not correctly (for those who use AI “smartly” or correctly, it’s more complicated to detect it). I’m pretty sure you already saw tons of ai-written posts on social media. For me, I started to notice this in January 2024. At this moment, I was shocked of seeing all these ai-written articles or comments and I decided to disclaim my AI uses

Turning Claude Code into My Best Design Partner

Published on August 18, 2025 When I first started using Claude Code, I had a naive approach to working with it. I would describe the task directly in the prompt, press Enter, and cross my fingers. If the agent made mistakes, I would tell it how to fix them. For small tasks, this can be good enough, but as the task grows in complexity, this approach reveals several significant drawbacks. When Simple Doesn’t Scale The first problem is that the conversation becomes the only source of truth about

What Is the Magnetic Constant and Why Does It Matter?

This means these three values can’t be independent; if you know two of them, you can derive the third. How do physicists deal with this? We define the speed of light as exactly 299,792,458 meters per second. (How do we know it’s exact? Because we define a meter as the distance light travels in 1/299,792,458 of a second.) Then we measure the magnetic constant (μ 0 ) and use that value along with the speed of light to calculate the electric constant (ε 0 ). Maybe that seems like cheating, but to

Overwatch 2 will allow KBM on console, but you'll be up against PC players

Overwatch 2 console players will officially be able to use a keyboard and mouse starting with the release of Season 18. In patch notes posted ahead of the new season, the Overwatch 2 team says matchmaking pools will be tweaked slightly so players are sorted into a Mouse and Keyboard Pool and a Controller Pool.

Stepanov's biggest blunder? The curious case of adjacent difference

The curious case of adjacent difference If you have ever tried using the std::adjacent_difference algorithm in c++, I’m sure it left you puzzled. As the name suggests, this algorithm computes differences between adjacent elements of the input sequence, but it does one more thing: it copies the first element of the input sequence into the output sequence unmodified. The following example demonstrates how to apply the algorithm to delta-compress a postings list of document identifiers that contain

Gutenprint Discontinues macOS Support

As of July 7, 2024 the Gutenprint project has formally deprecated MacOS support. This means that no further MacOS-compatible binaries will be produced. Gutenprint has not had an active MacOS maintainer for over three years, and the remaining developers lack the technical ability to produce MacOS binaries, much less undertake the substantial amount of work necessary to produce, test, and support binaries on newer (post-Mojave/10.14) MacOS releases. For older versions (<= 10.14) of MacOS, there

Recreationally overengineering my location history

That’s not because I didn’t overengineer things, I was busier starting projects as opposed to finishing projects. Today, we shall fix this lack of content. I like data.

Optimizing our way through Metroid

Will Wilson CEO Optimizing our way through Metroid Games People ask me: “why do you let your employees spend so much time playing Nintendo games?” People think we do it for the marketing. People think we do it to have cool demos. People think our blog series on learning autonomous testing concepts via how they come up in games is a pedagogical gimmick and nothing more. People are totally wrong. The honest truth, the underlying reality beneath the hype, is that this is actually how we figured
