Slashdot: New USB-C Logos Make Picking USB Cables, Chargers Less Confusing

New USB-C Logos Make Picking USB Cables, Chargers Less Confusing
Published on October 01, 2021 at 02:12AM
Choosing the correct USB-C charger and cable for you laptop is about as fun as visiting the dentist, but new logos released today should go a long way toward making easier. PCWorld: The USB Implementers Forum group that oversees the USB standard has released logos that easily indicate whether a cable or charger can hit the new 240 watt rating. Previous USB-C chargers and cables were rated to hit 65 watts or 100 watts but a new version of USB Power Delivery released this May has pushed the limit to an impressive 240 watts. Obviously, that means if you're looking for a 240 watt aftermarket charger for a new gaming laptop that supports it, you want one. With the new USB-C logos, all you have to do is look for a Certified USB Charger 240W logo with a lightning bolt like the one from the chart above. The other component you may need is a 240 watt USB-C cable, so consumers need only look for Certified USB Charger 240W with a cable in its logo. Both logos also can also be paired with USB 40Gbps bits to indicate if the cable is certified to support USB4's 40Gbps speed. The higher output 240 watt power range is a welcome addition to USB-C as it should allow laptop makers to bringing universal USB-C charging to far more powerful laptops, including gaming laptops with discrete graphics chips -- something that was out of reach of the previous USB-C chargers, cables, and ports. In fact, we found that we probably wouldn't want to use a small USB-C charger in a gaming laptop with today's technology. With 240 watt USB-C charger, we'd probably change our mind. The problem, of course, is that the USB-IF is an organization that certifies cables, chargers, and USB-C brick a brats, but it's not mandatory. This has lead to small brand and no-name manufacturers getting the spec wrong in the past. The good news is the cables from companies that actually obtain certifications correctly should work correctly.

Slashdot: Battery Fires At Recycling Centres Are Costing the UK £1bn a Year

Battery Fires At Recycling Centres Are Costing the UK £1bn a Year Published on 2026-08-23T00:29:00Z Wrongly discarded lithium batteries, such as those in vapes, are causing more than 10 fires a week at U.K. recycling centers, according to figures shared with the Guardian: The Environment Services Association (ESA), the trade body for waste management companies, said its members had reported 1,518 fires in the year to March 2026. At least 541 of these fires were directly attributed to lithium ion batteries, the survey found. There were a further 216 battery fires in bin lorries [garbage trucks]. The ESA said the reported number of battery-related fires underestimated the scale of the problem, because in most incidents it was impossible to determine the cause of the blaze. A spokesperson said: "We know 40% of fires at recycling centres are caused by batteries, but we think the actual number is more like 70%." It estimates that annual cost of these fires has increased from ...

Slashdot: How the FSF Sysadmins are Blocking Botnets with reaction

How the FSF Sysadmins are Blocking Botnets with reaction Published on 2026-07-11T21:47:00Z For nearly two years the Free Software Foundation has been fighting web crawlers (including many aggressively scraping training data for AI models). A botnet controlling about five million IPs hit one system for six months in 2025. Their systems administrator wrote this week that they view these as distributed denial-of-service attacks. How are they fighting back? We noticed patterns in the scrapers that were abnormal, which gave us material for writing regular expressions. Searching for the regular expression then gave us a large lists of IP addresses. Looking up the origin of those IP addresses revealed that some of the crawlers were using botnets of residential IP addresses to scrape faster and avoid detection. We looked for what kinds of botnets might be generating the kind of traffic that we were seeing, and one that we suspected was called the "Vo1d" botnet, comprised of sma...

AT&T Outlines $250 Billion US Investment Plan To Boost Infrastructure In AI Age Published on 2026-03-10T20:00:00Z AT&T plans to invest more than $250 billion over the next five years to expand U.S. telecom infrastructure for the AI age. The company says it will also hire thousands of technicians while partnering with AST SpaceMobile to extend coverage to remote areas. Reuters reports: Rapid adoption of artificial intelligence, cloud computing and connected devices has prompted telecom operators to invest heavily in fiber and 5G networks as they also seek to fend off intensifying competition from cable broadband providers. AT&T, which has about 110,000 employees in the U.S., said the new hires will help build and maintain its infrastructure. The outlay includes capital expenditure and other spending, the company said.
