Farewell to Endless Meetings: A New Approach to High-Velocity Software Development

2024-12-15

Tired of endless meetings and lengthy planning? This article introduces a high-efficiency software development method: code-centric, rapid iteration. The author uses baking as an example to illustrate the concept of achieving the optimal solution through rapid experimentation, frequent testing, and continuous improvement. This method emphasizes reducing documentation, expressing ideas directly in code, using mock data and hot-reloading tools to speed up development, and improving code readability through concise code style and naming conventions. The author advocates breaking down projects into independently executable files, minimizing restart time, and using default language tools for debugging. Although this method may seem like a "chaotic lab," it can efficiently complete projects and avoid the redundancy and inefficiency of traditional methods.

Eating Spaghetti by the Fistful: A Neapolitan Street Spectacle

In 19th-century Naples, eating spaghetti became a unique spectacle. People would grab handfuls of spaghetti and shove it into their mouths with surprising speed. This unusual custom attracted numerous tourists and became a Neapolitan specialty. The article traces the history of this practice, from the price drop of pasta in the 17th century, to its role as an important food source for the poor, and its eventual disappearance with societal changes.

TSMC Employees' Surprisingly High Fertility Rate: One in Fifty Taiwanese Babies is a 'TSMC Baby'

TSMC Employees' Surprisingly High Fertility Rate: One in Fifty Taiwanese Babies is a 'TSMC Baby'

The surprisingly high fertility rate among employees of Taiwan Semiconductor Manufacturing Company (TSMC), the world's leading semiconductor manufacturer, has drawn significant attention. While TSMC employees constitute only 0.3% of Taiwan's population, they account for 1.8% of all babies born in Taiwan—meaning one in every fifty Taiwanese babies is a 'TSMC baby'. This phenomenon is attributed to TSMC's family-friendly policies, including childcare services from 7 am to 8 pm, flexible work arrangements, and generous maternity leave. The company's culture, fostering positive peer interactions and encouraging parenthood, also plays a vital role, creating a positive feedback loop that boosts birth rates.

An Azerbaijan Airlines Embraer E190 passenger plane crashed on Christmas Day, killing 38 people. The Azerbaijani government confirmed that a Russian Pantir-S1 surface-to-air missile caused the crash. The aircraft was attempting an emergency landing when it went down. Russian air defense forces were engaged in shooting down Ukrainian drones in the area, but civilian airspace wasn't closed. Despite pilot requests for an emergency landing, the plane was denied access to Russian airports and crashed near Aktau, Kazakhstan.

NY Governor Signs Law Criminalizing Restaurant Reservation Black Market

New York Governor Kathy Hochul has signed the Restaurant Reservation Anti-Piracy Act, cracking down on the black market for restaurant reservations. This first-of-its-kind legislation targets individuals and groups using bots or manual methods to hoard and resell reservations at inflated prices. The law protects both consumers and businesses by ensuring a fairer reservation system, while acknowledging some legitimate reasons for reservation trading, such as handling non-refundable bookings in emergencies. However, the prevalent scalping and cancellations negatively impact restaurants and diners.

China to Subsidize Smartphone Purchases to Boost Spending

China to Subsidize Smartphone Purchases to Boost Spending

China will expand consumption subsidies to include smartphones and other electronics to boost domestic spending amid rising external headwinds. Officials from the nation’s top economic planning agency said Friday that a national trade-in program currently covering home appliances and cars will be broadened this year to personal devices such as phones, tablets, and smartwatches. Post-Covid, Chinese consumers have held onto their smartphones longer due to a lack of exciting new features and general belt-tightening. Like with cars and washing machines, investors hope incentives will revive the world’s largest smartphone market and drive sales not only for brands like Huawei and Xiaomi but also for platforms popular with device fans like Alibaba and JD.com. The move is part of China’s efforts to encourage consumption to offset the effects of potential new US tariffs on Chinese exports, a key growth driver. For only the second time in at least a decade, top leaders last month prioritized stimulating spending and domestic demand in 2025. The government will “significantly” increase the sale of ultra-long special treasury bonds to fund the program, which also encourages companies to upgrade equipment, according to Yuan Da, deputy secretary-general of the National Development and Reform Commission. Several provinces started their own trade-in programs for personal devices and phones in late 2024, but a nationwide initiative could prove more effective. The central government committed 300 billion yuan ($41.1 billion) of funds raised from special treasury bonds in July to support the subsidies. Including local government efforts, these incentives led to a surge in car and home appliance sales starting in September. Subsidies for upgrading business equipment will also be expanded to areas including agricultural facilities, according to Yuan. A specific plan for the program’s expansion will be released soon.

NASA's Goddard Space Flight Center has released a stunning visualization of global internal ocean tides, created using satellite altimetry data and simulations. The animation showcases how internal tidal waves, generated by the interaction of underwater topography, such as the Hawaiian Ridge, and tidal energy, propagate across the ocean. While these waves have a subtle surface expression, they play a significant role in ocean mixing and circulation. The visualization also highlights other regions with strong internal tidal activity, including Tahiti, the Southwest Indian Ocean, and the Luzon Strait, offering new insights into ocean dynamics.

Beyond NISQ: The Dawn of the Megaquop Machine

Beyond NISQ: The Dawn of the Megaquop Machine

Caltech's John Preskill delivered a keynote address at the Q2B 2024 conference, discussing the potential transition from the NISQ (Noisy Intermediate-Scale Quantum) era to the Megaquop (million quantum operations) era. Megaquop machines are envisioned to execute millions of quantum operations, albeit with a still-high error rate. Through error mitigation techniques and potentially higher-quality physical qubits, they could achieve tasks beyond the reach of classical computers and NISQ machines. Significant progress from teams at Google, AWS, and others in quantum error correction and hardware improvements lays the groundwork for Megaquop machines. However, Preskill highlighted challenges including decoding speed for quantum error correction, mitigating cosmic ray interference, and identifying commercially viable applications. Future applications of Megaquop machines might include simulations of complex quantum systems and materials science research.

Scheduled Reboots: A Preventative Approach

A university research team faced a challenging sysadmin problem: their servers had been running for too long and needed rebooting, but frequent reboots disrupt user experience. Their default was to avoid reboots, but a recent large-scale reboot due to prolonged uptime forced a change. To prevent similar issues, they've decided on a yearly reboot schedule—at least three times a year, aligning with the university's teaching schedule—balancing preventative maintenance with user experience.

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.
