Exceptions in Maths, which is odd since it's basically a giant calculator, and with tick questions, that it apparently can't identify and detect properly.It is not made clear the level of the courses beyond that it mainly appears to be undergraduate courses, there should still be a difference between first and last year in level. Perhaps there is a difference from first year courses where it's mostly a matter of reciting known facts and data to the later half when the requirements of more critical thinking and interpretation and analysis is required.Other findings include that AI plagiarism detecting is poor and mostly unable to tell which text was written by a human and which is regurgitated AI text blobs.Alternatively it could also be that the average student have just gotten worse over the years. The bottom end of the spectrum has increased as more and more students are forced into academia.https://www.nature.com/articles/s41598-023-38964-3

Polish railroads use the broadcasting of three tones on the 151.010 MHz frequency to instruct trains to stop. This occurred in three locations around Poland. Cheap radio equipment would be sufficient to issue the stop command, though it required that whoever broadcasted the signal would need to be in close proximity to the location affected. Despite the simplicity of the attack, there probably needed to be some coordination to broadcast the signals at different places in Poland.There is no authentication or encryption to issue the emergency stop command, though discussions on various forums suggest that only the stop command is broadcast in this manner. A general design principle in railroad signaling systems is that the default should be to stop trains. For example, the multi-colored signaling lights commonly used in the United States and Canada that still mechanically switch between colors will default to a red stop signal. Trains require long distances to stop, and defaulting to a stop signal will prevent collisions. Authorities in Poland insist that there was there was no safety risk to rail passengers, and this seems reasonable if the unauthorized broadcasts were only able to issue an emergency stop command but not to instruct trains to move.When this topic was discussed on Slashdot, it quickly turned to politics, but I find the technical aspects of this much more interesting. In North America, lights and semaphores are common and simple signaling mechanisms that have widespread use. For example, I know from experience that the same signaling system described in the video for use in Canada is also used on many BNSF main lines in the United States. However, other systems are also in use like the Advanced Train Control System (ATCS) and Positive Train Control (PTC). At some locations in the US, it was possible to use a software defined radio and software like ATCSMon to track the locations of trains in the area. However, railroads also generally also use unencrypted voice communications between trains and dispatchers, and these can still be monitored with a scanner.Read more of this story at SoylentNews.

The pearl octopuses, so named because from a distance they look like scattered gems, seek out warm water seeping through the seabed and use it to speed up the hatching of their eggs
