Mars Dichotomy Boundary Eroded Hundreds of Kilometers

Mars Dichotomy Boundary Eroded Hundreds of Kilometers

New research suggests Mars' iconic dichotomy boundary, separating the higher southern hemisphere from the lower northern one, may have receded hundreds of kilometers due to water erosion. Researchers analyzed data from the Mars Express and Mars Reconnaissance Orbiter, finding that thousands of buttes and mesas near Mawrth Vallis, situated at the dichotomy boundary, share a similar height with a nearby higher-elevation plateau, indicating they are remnants of a larger plateau eroded away. This massive erosion suggests an active water cycle early in Mars' history, consistent with the theory of a northern ocean but also potentially caused by other hydrological processes like ice cap melting. The finding offers new clues about early Martian climate and geological evolution, adding to evidence for a past ocean but also raising new questions.

Trump Admin Ends Paper Checks, Goes All-Digital

President Trump's executive order, effective September 30th, eliminates paper checks for all US Treasury disbursements. This includes tax refunds, vendor payments, benefits, and intergovernmental transfers. The move aims to combat waste, fraud, and abuse, citing that paper checks are 16 times more likely to be lost, stolen, or altered than electronic transfers. Maintaining the paper check system cost $657 million in 2024. While check usage declines, fraud is rising, prompting the American Bankers Association to applaud the change and encourage digital banking. Exceptions will be made for those lacking banking access, emergencies, law enforcement, and other specified cases.

Getting LLMs to Generate Funny Memes: Surprisingly Hard

Getting LLMs to Generate Funny Memes: Surprisingly Hard

A University of Waterloo intern attempted to build an app using LLMs and the Greptile API to generate memes that roast GitHub repositories. The process proved unexpectedly challenging. Directly prompting the LLM for roasts yielded generic results. The solution involved separating the task into code analysis (using Greptile to pinpoint specific issues) and roast generation (using the LLM to create targeted humor). Image generation proved difficult due to limitations in handling text, leading to the use of pre-built meme templates and node-canvas for text insertion. Despite the hurdles, the project culminated in reporoast.com, a website capable of generating custom code-roasting memes.

TSMC unveiled its 2nm platform technology at IEDM 2024, featuring energy-efficient nanosheet transistors and 3DIC co-optimization. The process boasts a 30% power improvement and 15% performance gain over its 3nm node, and is projected to be the densest in the 2nm class. However, analysis suggests that while early yield is impressive, a reported $30,000 per wafer price could hamper competitiveness, potentially opening the door for Intel and Samsung to gain market share. TSMC's 2nm node is expected to enter production in the second half of this year.

SpaceX Falcon 9 Launch Scrubbed 11 Seconds Before Liftoff Due to Delta Air Jet

A SpaceX Falcon 9 rocket launch was scrubbed with just 11 seconds to go on Sunday morning after a Delta Air Lines plane reportedly flew into restricted airspace near the launch site. The live broadcast of the launch showed the control room urgently calling "Hold, hold, hold!" as the launch was aborted at the 11-second mark. Investigations revealed the Delta Air Lines Boeing 767, en route from Los Angeles to Honolulu, flew over Vandenberg Space Force Base, the Falcon 9 launch site. The Federal Aviation Administration (FAA) will investigate how air traffic controllers allowed the Delta flight to enter the restricted airspace. This near-miss comes days after SpaceX's Starship rocket exploded, causing flight diversions.

Jupyter Notebooks and LLMs: An Unexpected Cost Optimization

2025-01-21

The author used LLMs for coding assistance, initially with a ContinueDev + OpenRouter setup. Costs unexpectedly soared. Investigation revealed that Jupyter Notebook (.ipynb) files contain significant hidden content (code outputs, metadata, base64-encoded images), leading to a large token count and increased LLM call costs. The solution was converting .ipynb files to .py files and removing base64-encoded images. This reduced costs by 94% and latency as well. The post highlights the importance of mindful input when using LLMs and recommends regularly checking costs.

The Vanishing Act of Government Information in the Digital Age

This post highlights the crisis of preserving government information in the digital age. Historically, paper government information was preserved in libraries, even outdated information wasn't readily deleted. However, in the digital age, government website information is easily altered or removed, leading to significant information loss. While some organizations strive to preserve government information, massive gaps remain, and the public can no longer assume the completeness and permanence of government information. The authors call for a new distributed digital preservation infrastructure to address this crisis, noting that information loss during the Trump administration exacerbated the problem.
