Yesterday, a New York Times reporter reported on how some delivery apps like DoorDash use your tip to make up the worker's base pay -- essentially stealing the money you're trying to give someone to maximize their profits. Following the backlash from that report, as well as others that exposed the controversial pay policy, DoorDash CEO Tony Xu announced his company will change its policy. Engadget reports: Without getting into specifics, which he said will be announced "in the coming days," Xu tweeted that his company misunderstood "that some customers who *did* tip would feel like their tip did not matter." So now, "the new model will ensure that Dashers' earnings will increase by the exact amount a customer tips on every order." Or, the way you probably thought tips worked.

Facebook-owned messaging app WhatsApp retains and stores chat logs even after those messages have been deleted, according to iOS researcher Jonathan Zdziarski. The Verge reports: Examining disk images taken from the most recent version of the app, Zdziarski found that the software retains and stores a forensic trace of the chat logs even after the chats have been deleted, creating a potential treasure trove of information for anyone with physical access to the device. The same data could also be recoverable through any remote backup systems in place. In most cases, the data is marked as deleted by the app itself -- but because it has not been overwritten, it is still recoverable through forensic tools. Zdziarski attributed the problem to the SQLite library used in coding the app, which does not overwrite by default. WhatsApp was applauded by many privacy advocates for switching to default end-to-end encryption through the Signal protocol, a process that completed this April. But that system only protects data in transit, preventing carriers and other intermediaries from spying on conversations as they travel across the network.

Doomsayers Delight writes "The Telegraph reports that Greek hackers were able to gain momentary access to a CERN computer system of the Large Hadron Collider (LHC) while the first particles were zipping around the particle accelerator on September 10th. 'Scientists working at CERN, the organization that runs the vast smasher, were worried about what the hackers could do because they were "one step away" from the computer control system of one of the huge detectors of the machine, a vast magnet that weighs 12,500 tons, measuring around 21 meters in length and 15 meters wide/high. If they had hacked into a second computer network, they could have turned off parts of the vast detector and, said the insider, "it is hard enough to make these things work if no one is messing with it."'"
