testtrim: The Testing Tool That Couldn't Test Itself (Until Now)

2025-01-25

Mathieu Fenniak details his journey adding syscall tracing to testtrim, an experimental project optimizing software test execution. Initially, testtrim used strace to identify test dependencies but couldn't test itself because strace can't trace an already-traced process. Two nested tracing attempts failed: the first due to abysmal performance, the second due to shared state and non-atomicity in strace's output. The solution involved using FIFO pipes and shared memory for real-time data streaming between parent and child processes, enabling self-testing and validating testtrim's value in reducing test targets.

Schrödinger: The Biotech Firm Trying to Crack the AI Drug Discovery Code

Schrödinger, a biotech company using quantum mechanics to design new medicines and materials, boasts all top 20 pharmaceutical companies as clients. Despite this, five years post-IPO, its stock price languishes near all-time lows. This article explores Schrödinger's unique business model—part biotech, part software—and its struggles with valuation. A pivotal dinner between Nvidia's Jensen Huang and Schrödinger's CEO highlighted a crucial turning point: embracing AI more fully. While initially hesitant, Schrödinger now leverages AI's power, particularly AlphaFold's protein structure predictions, and is preparing for crucial clinical data releases in 2025. The company's future hinges on successfully navigating the complex interplay of software sales, biotech pipeline development, and clear investor communication.

Building a Silicon Brain: The Future of Neuroscience

Researchers at UCSF are using AI and cutting-edge neuroimaging technologies to build a 'silicon brain' that mimics human brain activity. By integrating data from various brain scanning techniques (like fMRI and neuropixel probes), along with text, speech, and behavioral data, they're creating an artificial neural network that replicates human brain activity patterns. This research promises to revolutionize brain-computer interfaces, enabling devices that restore speech or movement without extensive calibration and opening new avenues for diagnosing and treating neuropsychiatric disorders. Ethical considerations, such as data privacy and potential misuse, are also being addressed.

Heat Pumps Surpass Gas Furnaces in US Sales: A Clean Energy Win?

Heat pump sales in the US surged 37% in the first 11 months of the year, outpacing gas furnaces to become the most popular heating appliance. This 21% year-over-year increase is driven by their superior efficiency, lower carbon emissions, and technological advancements enabling use in colder climates. While installation costs remain high ($17,000-$30,000), government incentives (like the Inflation Reduction Act) and growing consumer awareness are boosting adoption. However, price, compatibility issues, and concerns about grid reliability remain barriers. Future growth hinges on effective communication highlighting long-term savings and improved home comfort.

Why You Should Ditch Query Builders and Embrace Raw SQL

2025-01-25

This article champions writing database queries directly in SQL instead of relying on query builders. Through several examples, the author demonstrates how SQL features (like `IS NULL`, `COALESCE`, `ARRAY_REMOVE`, `STRING_TO_ARRAY`) elegantly handle optional parameters, arrays, pagination, and batch updates, reducing complex Rust logic. This approach simplifies code, improves readability and testability, and enables easier database testing and debugging. The author argues that raw SQL is often cleaner and more efficient than complex builder patterns.

A 70-year study tracked the emotional support networks of 235 men. Results showed a 50% average decrease in support providers from ages 30 to 90, dropping from two to one. Warm family environments predicted larger adult networks, while childhood socioeconomic status had less impact. Marriage reduced network size, but retirement did not. The study highlights the lasting influence of early family dynamics on socioemotional development, but acknowledges sample limitations.

Giant, Mysterious Spires Pre-Dated Trees: Unraveling the Prototaxites Puzzle

Towering 24 feet tall and 3 feet wide, the enigmatic Prototaxites fossils have baffled scientists for over 150 years. These giant spires predate large trees, existing between 350 and 420 million years ago. Initially classified as plants, various hypotheses have been proposed, including algae, fungi, and lichens. A 2007 study using carbon isotope analysis provided strong evidence supporting the fungal hypothesis, suggesting Prototaxites were giant fruiting bodies. However, the debate continues, highlighting a bizarre and fascinating prehistoric landscape.

Musk's DOGE: A New Tool for Government Surveillance?

The Trump administration renamed the US Digital Service (USDS) to "US DOGE Service," headed by Elon Musk. This has raised concerns as DOGE will gain access to unclassified data across all government agencies, potentially used for surveillance or targeting political opponents. While officially aimed at improving efficiency, this move bypasses the Federal Advisory Committee Act, lacks transparency, and may lead to conflicts of interest and regulatory capture. DOGE's dual structure—a permanent and a temporary organization—further fuels these concerns, with the temporary one able to hire special government employees bypassing rigorous scrutiny.

Why North England Remains Economically Depressed: A Historical Perspective

2025-01-25

This article delves into the deep-seated reasons behind North England's economic underperformance, arguing it's not simply an economic issue but a consequence of historical power structures and political decisions. From the Norman Conquest to the Thatcher era, power has been concentrated in the South, leading to chronic underinvestment and resource disparities in the North. The author highlights the South's consistent neglect and preferential treatment, coupled with a lack of regional power balance, as crucial factors in the North's economic stagnation. Despite this bleak picture, the article expresses optimism about the North's future, suggesting that reforming power structures and resource allocation is key to reversing the trend.

TikTok Ban Fuels $50K iPhone Resale Market

With TikTok facing a potential US ban, users are listing phones pre-loaded with the app for exorbitant prices—up to $50,000—on eBay and Facebook Marketplace. While TikTok is temporarily accessible again, it's unavailable for download, creating a surge in demand for used devices with the app already installed. Sellers are capitalizing on this, listing iPhones and tablets with TikTok and other ByteDance apps (Lemon8, CapCut) for prices ranging from $340 to $50,000. While high-priced listings exist, most sales appear to be in the hundreds of dollars. This reflects user reliance on TikTok and the market's response to scarcity.
