Elixir/Erlang Hot Code Swapping: Zero-Downtime Deployments

2024-12-13

This article delves into Elixir/Erlang's hot code swapping capabilities, enabling the loading and unloading of code at runtime without requiring system restarts for application upgrades. A simple KV module example demonstrates manual hot swapping, while iex's c/1 and r/1 commands, and the Relups tool, are introduced for easier application and release upgrade management. The article explains Erlang applications, releases, appups, and relups, detailing the use of the Distillery tool to generate application releases and upgrade releases, ultimately achieving zero-downtime deployments and preventing service interruptions.

Why Cancer Guidelines Remain Stuck in PDFs

Why Cancer Guidelines Remain Stuck in PDFs

Cancer treatment guidelines are often presented as unwieldy PDFs, hindering standardization of care. The author argues that guidelines are essentially complex decision trees; converting them into machine-readable, structured data could significantly improve cancer treatment. A prototype tool was developed using LLMs to extract information from the NCCN breast cancer guidelines PDF, creating a visual decision tree and an agent that navigates the tree based on patient information to suggest treatment. While early-stage, this demonstrates the potential of structuring guidelines to enhance efficiency and standardization in healthcare.

LA Highway Guardrail Thefts Surge: AI Surveillance Offers a Potential Solution

A surge in guardrail thefts on Los Angeles freeways is jeopardizing public safety. Over the past two years, repairs have cost over $62,000. Thieves target aluminum guardrails due to rising aluminum prices and ease of resale at scrap yards. Caltrans' attempts to deter theft by welding bolts have failed, leading them to consider fiberglass composite materials. Beyond guardrails, copper wire and cable theft also plagues the city, disrupting essential infrastructure like power and transit. AI surveillance systems are being deployed in some areas to detect and predict suspicious activity, offering a new approach to combating metal theft.

Ammonia-Fueled Ship Viking Energy Delayed Until 2026

Ammonia-Fueled Ship Viking Energy Delayed Until 2026

The world's first full-time ammonia-fueled ship, Viking Energy, originally slated for launch in 2024, has been delayed until 2026 due to the complexities of building the necessary ammonia infrastructure. Ammonia's toxicity, explosiveness, and corrosive nature require specialized piping, storage, and transport. Furthermore, ammonia combustion produces nitrogen oxides, necessitating emission control technologies. Despite challenges, experts believe ammonia will eventually become a mainstream marine fuel. They suggest seaports become energy hubs producing, storing, and trading alternative fuels to solve the chicken-and-egg problem of fuel supply and ship construction.

Critical Hurricane Forecasting Data to be Cut, Threatening Accuracy

Critical Hurricane Forecasting Data to be Cut, Threatening Accuracy

Sensors aboard Defense Meteorological Satellite Program (DMSP) satellites will cease providing crucial microwave data to the National Hurricane Center and other non-Department of Defense users by June 30th, significantly impacting hurricane forecast accuracy. This data allows for viewing a storm's internal structure, especially changes to its eye and eyewall, giving forecasters hours of advanced warning of rapid intensification. The reasons for the shutdown remain unclear but may be related to security concerns. While NOAA claims to have alternative data sources, experts worry this could lead to 6-12 hour delays in hurricane forecasts, potentially devastating for Pacific storms and dangerous for mariners.

JWST Discovery: Was the Universe Born Inside a Black Hole?

JWST Discovery: Was the Universe Born Inside a Black Hole?

The James Webb Space Telescope (JWST) has made a startling discovery: most early universe galaxies rotate in the same direction, contradicting random universe models. One explanation is that the universe was born rotating, aligning with 'black hole cosmology,' which posits our universe resides inside a black hole. This challenges existing cosmological theories, suggesting each black hole might birth a new 'baby universe'. The research, published in the Monthly Notices of the Royal Astronomical Society, prompts a re-evaluation of the universe's origins and may necessitate recalibrating deep-space distance measurements.

Rust is making inroads into the Linux kernel, but the transition will be a long and contentious one. While Rust offers significant advantages in memory safety and is backed by companies like Google, its adoption faces strong resistance within the kernel community. Concerns about its steep learning curve and integration challenges with existing C code have sparked heated debates, even described as a “religious war.” However, proponents argue that Rust improves kernel stability and security, attracting more developers. Ultimately, Rust's complete replacement of C depends on technological maturity and community consensus.

Trump Tariffs: The Impact on Tesla – Debunking the Myths

Despite the rosy outlook painted by some Tesla fans, the reality is that President Trump's tariffs on Mexico and Canada will negatively impact Tesla. Data reveals that Tesla sources over 20% of its parts from Mexico, with additional components coming from Canada. This means the recently delayed (again, for another month) tariffs will inevitably increase Tesla's production costs, affecting vehicle prices and profitability. Tesla's stock reaction to the tariff delay further underscores this impact. Elon Musk's close relationship with Trump, and his seeming inaction against the tariffs, adds a layer of complexity. The long-term effects may extend beyond mere cost increases, potentially damaging US business relationships with Canada and Mexico.

He noted that young researchers have to turn off their phones to focus on in-depth research. Schmidt acknowledged that the tech industry has long sought to "monetize your attention," contradicting traditional human practices of prolonged, thoughtful reflection. Research shows our attention spans are shrinking, partly due to technology's interruptions.
