Open-Source Tool Designed To Throttle PC and Server Performance Based On Electricity Pricing

1 hour 38 minutes ago
Robotics and machine learning engineer Naveen Kul developed WattWise, a lightweight open-source CLI tool that monitors power usage via smart plugs and throttles system performance based on electricity pricing and peak hours. Tom's Hardware reports: The simple program, called WattWise, came about when Naveen built a dual-socket EPYC workstation with plans to add four GPUs. It's a power-intensive setup, so he wanted a way to monitor its power consumption using a Kasa smart plug. The enthusiast has released the monitoring portion of the project to the public now, but the portion that manages clocks and power will be released later. Unfortunately, the Kasa Smart app and the Home Assistant dashboard was inconvenient and couldn't do everything he desired. He already had a terminal window running monitoring tools like htop, nvtop, and nload, and decided to take matters into his own hands rather than dealing with yet another app. Naveen built a terminal-based UI that shows power consumption data through Home Assistant and the TP-Link integration. The app monitors real-time power use, showing wattage and current, as well as providing historical consumption charts. More importantly, it is designed to automatically throttle CPU and GPU performance. Naveen's power provider uses Time-of-Use (ToU) pricing, so using a lot of power during peak hours can cost significantly more. The workstation can draw as much as 1400 watts at full load, but by reducing the CPU frequency from 3.7 GHz to 1.5 GHz, he's able to reduce consumption by about 225 watts. (No mention is made of GPU throttling, which could potentially allow for even higher power savings with a quad-GPU setup.) Results will vary based on the hardware being used, naturally, and servers can pull far more power than a typical desktop -- even one designed and used for gaming. WattWise optimizes the system's clock speed based on the current system load, power consumption as reported by the smart plug, and the time -- with the latter factoring in peak pricing. From there, it uses a Proportional-Integral (PI) controller to manage the power and adapts system parameters based on the three variables. A blog post with more information is available here. WattWise is also available on GitHub.

NaNoWriMo To Close After 20 Years

2 hours 16 minutes ago
NaNoWriMo, the nonprofit behind the annual novel-writing challenge, is shutting down after 20 years but will keep its websites online temporarily so users can retrieve their content. The Guardian reports: A 27-minute YouTube video posted the same day by the organization's interim executive director Kilby Blades explained that it had to close due to ongoing financial problems, which were compounded by reputational damage. In November 2023, several community members complained to the nonprofit's board, Blades said. They believed that staff had mishandled accusations made in May 2023 that a NaNoWriMo forum moderator was grooming children on a different website. The moderator was eventually removed, though this was for unrelated code of conduct violations and occurred "many weeks" after the initial complaints. In the wake of this, community members came forward with other complaints related to child safety on the NaNoWriMo sites. The organization was also widely criticized last year over a statement on the use of artificial intelligence in creative writing. After stating that it did not support or explicitly condemn any approach to writing, including the use of AI, it said that the "categorical condemnation of artificial intelligence has classist and ableist undertones." It went on to say that "not all writers have the financial ability to hire humans to help at certain phases of their writing," and that "not all brains have same abilities ... There is a wealth of reasons why individuals can't 'see' the issues in their writing without help." "We hold no belief that people will stop writing 50,000 words in November," read Monday's email. "Many alternatives to NaNoWriMo popped up this year, and people did find each other. In so many ways, it's easier than it was when NaNoWriMo began in 1999 to find your writing tribe online."
