Info Updates: After giving a second thought on the topic and reorganizing the materials, I had a sharing session with my teammates and decided to update this article accordingly. Updates include more suitable examples and graphics. Info Updates 2: It is revised again and published as a preprint. Now you can see it at https://arxiv.org/abs/2503.17813 or https://katsuragicsl.github.io/papers/connectedness/ An empty business lingo or a good quantification? We hope to, and probably need to, quantify the severity of security bugs....

After the huge attention gained by deepseek R1, I have seen a good amount of people immediately went to looking for censorships (which are expected to exist), laughed at it, and looked down on it. They totally missed the points and these behaviors made them look like slaves of their very own defense mechanism1. Deepseek did make some techonological breakthroughs. Indeed the censorship is a defect of such a great product....

Just added support for tikzjax since I received some feedback about my hand-drawn diagrams are hard to read…now I can use nice graphs like these: source: https://tikzjax.com/ source: https://tikzjax.com/ source: https://tikz.net/ source: https://tikz.net/

That said, the author is not a lawyer and does not have accurate knowledge of any concrete laws. But one does not need to know (too many of) them for this article....

Why ignore 50% of what we know about the data1 Everyone learnt binary search in Algo 101. It is the fastest way (among comparison based searches) to find an element in a sorted array. All you need to carry out the algorithms is the comparison between the target element and the element at the current position. It is widely applicable because it assumes so little from the data. But for many real life problems, we do often know something apart from merely the comparison between the two numbers....
