Support CleanTechnica’s work through a Substack subscription, on Patreon, or on Stripe. Help us produce all of the high-quality, original content we publish week after week despite the challenges of content-scraping AI, antisocial media, inflation, and other hurdles. Much of the economic concern around artificial intelligence (AI) is from the expectation that AI will lead to millions upon millions of job losses. Professional drivers, writers, lower-level software engineers, and even young lawyers are expected to lose their jobs en masse — or already are. But what about massively overpaid CEOs? At the top of the “food chain,” there are a…

IoT botnet Dysphoria has infected over 200,000 devices, hiding command servers on Ethereum and Solana blockchain domains. The botnet family first appeared in the wild in March 2026, and X Lab, the research arm of QAX, has tracked its development since.X Lab published its findings jointly with the National Computer Network Emergency Response Technical Team/Coordination Center of China (CNCERT). Researchers describe a network built on Linux-based IoT malware code lineages known as jackskid and fbot, which Dysphoria’s authors have reworked repeatedly over months rather than years.How blockchain domains replace command serversMost botnets rely on hardcoded IP addresses or domain names…

Busy homes can make an older router feel like the weak link, especially when multiple people are streaming, gaming, working, and downloading at once. The good news is there’s a great deal on the TP-Link BE6500 router at Amazon right now, and it looks like a strong pick for anyone ready to move on from an ISP router or aging Wi-Fi 5 or Wi-Fi 6 setup. The TP-Link BE6500 Dual-Band Wi-Fi 7 Router is down to $114.99 from its $179.99 RRP. That’s a 36% discount relative to the recommended retail price, saving you $65. It’s also an all-time low price.…

An agile initiative is not mainly a one-time rollout of Scrum, Kanban, SAFe, Jira, new job titles, or a different meeting calendar. Those changes may be part of the work. But they are not the point. The point of an agile initiative is to improve an organization’s ability to deliver valuable work, learn from feedback, respond to change, and make better decisions under uncertainty. Treating the effort as a rollout leads to a very different set of leadership behaviors than treating it as an ongoing improvement effort. A rollout can be managed mostly as a project: train people, rename roles,…

We’ve seen this story After all, since then we’ve seen the likes of Cambridge Analytica and the evolution of digital state surveillance (and state-adjacent surveillance “businesses” such as NSO). We’ve also seen the dubious rise of data brokers, creepy “personalized” ads that seem to follow private conversations around, and all the other parasites that breed in the murk when privacy is diluted. None of these things is good. More people than ever now seem to understand that when privacy is removed, bad things happen — no matter what herds of fully paid-up lobbyists try to make people believe. Privacy erosion…

Unlike many budding engineers, K.J. Ray Liu wasn’t inspired to enter the field by tinkering with electronics or following in the footsteps of a family member. Growing up in Taichung, Taiwan, he answered his government’s call for students to become electrical engineers to help manufacture semiconductors in the 1970s, when the country’s economy was struggling.“Students who were good in math, science, and physics all wanted to be an electrical engineer because that was the top priority of the government,” Liu says. “That’s how I got into engineering. Now Taiwan is a world leader in semiconductors.” K.J. Ray Liu OccupationRetired professor…

Nuclear power provides about 9% of global electricity today, and that fraction could tick up as major world powers like the US and China look to build new reactors, including some based on next-generation technology. New, cheaper methods to obtain fuel could help ensure that those nuclear projects stay on track. Naturally occurring uranium is largely made up of uranium-238 (over 99%) and uranium-235 (about 0.7%). Uranium-235 is the fissile type, meaning that, when hit with slow low-energy neutrons, it can sustain a chain reaction that generates electricity. So reactors generally use material with a higher concentration of U-235 than…

Store one petabyte on Azure’s hot tier for five years and the bill runs close to $1.2 million, before you’ve moved a single byte back out. Try to retrieve that data and the cloud charges again: AWS bills roughly $90,000 in egress fees to pull a single petabyte off its platform, and Google Cloud Storage charges even more per gigabyte on the way out than AWS does. At ten, fifty, or five hundred petabytes, that arithmetic stops being a line item and starts being a strategic decision. This guide covers the real options for storing petabyte-scale data outside a public…

Recently, I am experiencing a CKErrorServerRejectedRequest error during my app’s iCloud data sync process. I have not modified or migrated the schema recently. To troubleshoot, I logged into the iCloud Dashboard (CloudKit Console) to query the records directly. However, the dashboard also returns a generic “Internal Error” with no additional details whenever I attempt a query. Here is what I have tried so far: Private Database Only: The error only occurs within the Private Database. Querying the Public Database works normally and correctly returns “No records found.” Multiple Containers: This issue affects all of my existing containers across both Development…
