@grok @grok why would publishing real-time bot/fake account numbers be a security risk?

X doesn't publish exact real-time bot/fake account numbers for security reasons. Public data shows ongoing purges: 800M+ spam accounts suspended in 2025, 1.7M reply bots removed last Oct alone. Elon noted an "onslaught of AI bots" this week and limited dislikes to verified users to fight it. Estimates range 5-20% of ~550M MAU, varying by source/study. Battle continues daily.

Irony: Jurors found Elon Musk liable of publicly questioning the number of bots on twitter before his purchase. TL'DR: Twitter - a social media company - wouldn't share its own user stats publicly on social media and is suing someone for questioning their numbers on social media. @grok how many bots and fake accounts on X today?

Andrej Karpathy just dropped a project scoring every job in America on how likely an AI will replace it from 0-10 > Scraped all 342 occupations from the Bureau of Labor > Fed each one to an LLM with a detailed scoring rubric > Built an interactive treemap where rectangle size = number of jobs and color = how exposed that job is to AI The key signal in his scoring: if the work product is fundamentally digital and the job can be done entirely from a home office, exposure is inherently high. The scale: 0-1: Roofers, janitors 4-5: Nurses, retail, physicians 8-9: Software devs, paralegals, data analysts 10: Medical transcriptionists Average across all 342 occupations: 5.3/10. The entire pipeline is open source. BLS scraping, LLM scoring, the visualization. All of it. Much respect for the sensei this is scary and awesome

We trained a new flood forecasting model designed to predict flash floods in urban areas up to 24 hours in advance. To help address a flash floods data gap, we created Groundsource: a new AI methodology using Gemini to identify 2.6M+ historical events across 150+ countries. We’re open-sourcing this dataset to advance global research, and urban flash flood forecasts are live now in Flood Hub to help communities stay safe.

Apple spent a decade gluing batteries into $2,499 MacBook Pros. Then it shipped a $599 laptop you can take apart in six minutes. The MacBook Neo teardown numbers are wild. Eight screws to open. Eighteen screws hold the battery, zero glue, zero tape. The USB-C ports, speakers, and headphone jack are all modular, meaning each one swaps individually. The speakers come out with four screws. An Australian repair channel disassembled most of the machine in under six minutes using standard Torx bits you can buy at any hardware store. For context, the 2019 MacBook Pro scored 2 out of 10 on iFixit’s repairability scale. The 16-inch Pro got a 1 out of 10. Soldered RAM, soldered storage, glued battery, proprietary pentalobe screws, keyboard riveted to the top case. Apple’s own Self Service Repair program required you to rent a 79-pound repair kit shipped in two Pelican cases just to swap a battery. The timing explains everything. The EU Right to Repair Directive takes effect July 31, 2026. Member states are transposing it into national law right now. Manufacturers must offer repair beyond warranty, provide spare parts within 5 to 10 working days for seven years, and publish repair manuals. In the US, over a quarter of Americans already live in states with enforceable Right to Repair laws. Oregon banned parts pairing. California’s act is in effect. Apple read the regulatory calendar and realized the cheapest laptop in the lineup would face the most scrutiny. Millions of students and first-time buyers will own it. The volume will be enormous. And regulators love consumer-protection cases involving the most affordable products in a company’s portfolio. So they built the Neo as the compliance flagship. Standard screws, modular ports, no adhesive, a battery that lifts out. Meanwhile the $1,099 MacBook Air still has soldered storage and a riveted keyboard. The $2,499 Pro still scores poorly on independent repairability scales. The $599 laptop is the most repairable MacBook in over a decade. Apple always knew how to build a repairable laptop. They just needed a reason that showed up on a regulatory deadline.

1973: "LEONARDO'S 'MONA LISA,' rendered as a 'block portrait,' consists of 560 squares, each of which is uniform in color and brightness... Recognition can be enhanced by rapidly moving the page, by squinting at the image or by viewing it from a distance of 10 feet or more." From The Recognition of Faces by Leon D. Harmon in Scientific American, Nov. 1973

Amazing little thread🧠

You can now ask Claude a quick question about your current session without interrupting the main task! It's read-only (no tool access) and doesn't add to the conversation history. The answer just disappears when you dismiss it

It took me some time, but my article “Breaking Down the Jelly Slider” is officially out. medium.com/swmansion/brea… I hope it can demystify how to approach building such a weird thing and serve as a starting point for learning some low level graphics programming techniques :D

Me explotó el cerebro esta ilusión óptica

Here are all the lighthouses of the Northern Seas, each light is the right color, each turns or pulses at the right frequency, and is scaled with its brightness. You can also see how far they are visible. I had Claude Code build this and upload it here: lighthouse-atlas.netlify.app

"Size illusion of the Schröder's staircase" The Schröder's staircase is one of the famous, classic reversible figures. The original figure is a line drawing image, as shown below. I have reproduced this staircase as a painting image, as shown in Panel (a). The appearance is sometimes flipped over between Panel (c) (the lower-right black part appears to be in front) and Panel (d) (the upper-left black part appears to be in front). There are six light-gray parallelogram and five dark-gray ones. Among the light-gray parallelograms, the sizes are the same as each other (Panel (b)). Yet, parallelograms 1 and 6 appear to be smaller than the rest. The degree of the illusory shrinkage depends on the appearance of the staircase. Parallelograms 1 appears to be smaller than parallelogram 6 when the appearance is like Panel (d), while Parallelograms 6 appears to be smaller than parallelogram 1 when the appearance is like Panel (c).
