Profitable Startups: The Underrated Path to Success

For years, startups prioritized growth above all else, viewing profitability as secondary. Linear, however, demonstrates a different path. By maintaining a lean team focused on building a superior product, they achieved profitability within a year and have sustained it since. The author argues that smaller teams are more efficient, while rapid expansion often diminishes efficiency and product quality. Profitability offers not just financial freedom, but the crucial ability to focus on value creation rather than fundraising. The article advocates for startups to prioritize metrics like revenue per employee and to rationally manage team size based on their risk profile and market conditions, enabling earlier profitability and control over their destiny.

Bybit Suffers $1.46B in Suspicious Outflows: Largest Crypto Hack Ever?

Cryptocurrency exchange Bybit has reported $1.46 billion in suspicious outflows, according to blockchain investigator ZachXBT. A wallet transferred 401,346 ETH ($1.1 billion) and various staked ETH (stETH) to a new wallet, which is now liquidating assets on decentralized exchanges, according to Etherscan. Around $200 million worth of stETH has already been sold. Bybit CEO Ben Zhou confirmed the hack on X, stating that a hacker gained control of a specific ETH cold wallet. He assured users that other wallets are secure and withdrawals are normal, emphasizing Bybit's solvency even if the loss isn't recovered. This potential hack dwarfs previous major events like the Mt. Gox ($470M), CoinCheck ($530M), and Ronin Bridge ($650M) hacks, making it potentially the largest crypto hack in dollar terms. BTC and ETH prices dropped following the news.

The Forgotten Genius: Henri Bergson's Philosophy for Our Times

At the turn of the 20th century, Henri Bergson was one of the world's most famous philosophers, his lectures drawing enormous crowds. Today, however, he's largely forgotten. Emily Herring's new biography, *Herald of a Restless World*, revisits Bergson's philosophy and its relevance to our time. Bergson challenged the absolutes of science, emphasizing the constant flux of reality and introducing concepts like *durée* and *élan vital*. Despite a famous debate with Einstein on relativity and eventual eclipse, Bergson's insights into change and creativity resonate powerfully in the face of modern challenges like the climate crisis.

Apple Pulls Advanced iCloud Data Protection from UK After Government Backdoor Demand

Apple has withdrawn its Advanced Data Protection (ADP) iCloud feature from the UK following a government mandate for backdoor access to encrypted user data. The UK government, via a technical capability notice under the Investigatory Powers Act, demanded unrestricted access to encrypted iCloud content globally. Apple, prioritizing user security over compliance, chose to remove ADP rather than create a backdoor, citing the risk of malicious actors exploiting such access. While this affects iCloud data backups, other Apple services like iMessage and FaceTime remain end-to-end encrypted. The decision highlights the ongoing tension between government surveillance and user privacy in the digital age.

Inside the Ryugyong Hotel: A Rare Glimpse into North Korea's Empty Giant

The Ryugyong Hotel in Pyongyang, one of the world's tallest unoccupied buildings, has finally had some of its mystery unveiled by British tour guide Simon Cockerell. After nearly 200 visits to North Korea, Cockerell's connections allowed him access to the peculiar pyramid-shaped structure. His photos reveal a vast emptiness, debunking myths about the building's size and features. Despite its completion, the hotel has never hosted a guest, a testament to North Korea's ambitions and economic struggles, particularly after the fall of the Soviet Union. Today, the Ryugyong's glass facade serves as a nightly LED screen, projecting propaganda and videos, becoming a unique part of Pyongyang's skyline.

Stop Chasing Tech Trends: Focus on What Matters

Programmers often get bogged down in technology choices, debating which language or framework is superior. But the truth is, users don't care! They won't notice those extra 10 milliseconds you saved, nor will their experience magically improve because you're using the latest JavaScript framework. What truly matters is your focus on the product and user needs. Every programming language and framework excels in specific contexts, but technical decisions alone won't define your product's success. Instead of chasing hype, choose technologies you're familiar with, enjoy working with, and that challenge you to improve daily. Finding the right balance between tech choices and product value is key to building something truly impactful.

eserde: Reporting Multiple Deserialization Errors at Once

The serde library aborts deserialization upon encountering the first error, which is inconvenient when dealing with user-provided JSON payloads (e.g., a REST API request body). eserde solves this by reporting all deserialization errors at once, significantly improving the developer experience. By replacing `#[derive(serde::Deserialize)]` with `#[derive(eserde::Deserialize)]` and using eserde's deserialization functions, developers can easily obtain all error messages, reducing the number of API interactions. eserde currently supports JSON and plans to support YAML and TOML in the future.

Append-Only Programming: A Fun Experiment

2025-02-21

The author experimented with a new software development methodology called "append-only programming": all code resides in a single C file, new code is appended to the end, and editing existing code is forbidden. This forces programmers to define interfaces upfront, write small functions, and produces highly readable code. However, this approach is error-prone; if a function is erroneous, a corrected version must be appended, and all callers must be corrected, potentially requiring rewriting the entire program. The author experimented with a Lisp interpreter and found it tedious. Ultimately, the author concludes it's a fun challenge but not a practical software development method, suggesting improvements such as using header files or one file per function.

A Surprisingly Effective Cure?  The Case for More Academic Fraud in AI

This blog post argues that widespread, subtle academic fraud in AI research – cherry-picked results, manipulated datasets, etc. – has normalized low standards, resulting in publications lacking scientific merit. The author provocatively suggests that a recent, highly publicized case of explicit academic fraud could be a turning point. By forcing a reckoning with the community's blind spot, the scandal may ironically lead to increased scrutiny of all research, ultimately fostering higher standards and more truthful publications. The author believes this harsh, even self-destructive, approach might be the best way to cure the cancer of low standards in AI research.

The mysterious number 2.92005097731613..., known as the Buenos Aires constant, generates a sequence of prime numbers when used to initialize a simple Python script. This isn't a coincidence; the constant's definition is intrinsically linked to prime sequences. However, due to computational precision limitations using the IEEE 754 standard, the algorithm fails after generating a certain number of primes. This raises questions about the deeper connection between mathematical constants and primes, highlighting the impact of computational accuracy on mathematical experimental results.
