David Kriesel: Lies, damned lies and scans
推荐理由
There a few videos of David Kriesel explaining the bug for the curious
说明
这是2015年由Free and Open Source Software Conference (FrOSCon) e.V.发布的一部演讲,主题归在Information theory & signal processing。它讲的是xerox jbig2 scanner bug这一支里的具体问题,而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成:David Kriesel's FrOSCon talk on how Xerox scancopiers, due to JBIG2 compression, silently replaced digits in scanned documents. He walks through how he discovered the bug and why it is so dangerous.这些读者给出的理由,核心是:The standard reference whenever HN discusses the Xerox scanner bug or AI and compression that fabricates content.讲法不绑某一条新闻,过几年仍然可以当材料看。从2020年到2026年,有2位不同的读者在2个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合一次性看完。讲者把一个判断讲透,演示是在给这个判断配例子。如果已经会了基本定义,就把注意力放在它怎么把xerox jbig2 scanner bug变成能跟着复述的例子。
