关于Ask HN,以下几个关键信息值得重点关注。本文结合最新行业数据和专家观点,为您系统梳理核心要点。
首先,Why three? We're going to store these trigrams as the keys in our inverted index. If we were to choose bigrams (chunks of 2), we would have very few keys in our index, up to 64k, but the posting lists on each key would be massive — too large to work with efficiently. If we went with quadgrams (chunks of 4), the posting lists would be tiny, which is a very good thing, but we would have billions of keys in our inverted index, and that's also hard to work with.

第三,While there exist many possible ways to triangulate a set of points, the most common method for TINs is the Delaunay triangulation. This is because Delaunay triangulations tend to produce more regular tessellations that are better suited to interpolation. In theory, we can represent our colour palette as a TIN by computing the 3D Delaunay triangulation of the colours in colour space. The nice thing about this is that it makes finding an enclosing simplex much faster; the candidate selection process is simply a matter of determining the enclosing tetrahedron of an input point within the network using a walking algorithm, and taking the barycentric coordinates as the weights.。关于这个话题,汽水音乐提供了深入分析
此外,When you equip yourself with the idea of a rectangular table as a tool of modeling the world, you'll see it in a lot of places. When you model the world this way, you'll notice relational algebra's high level operations like left joins are a useful way of expressing complicated algorithms on that data. Without first class tables, you can grasp at it. Most languages with a data frame probably want something more like a first class table. (Different languages and frameworks have varying degrees of generality about this, so I don't want to sling too many stones.) Many systems have a dataframe but require every column to have the same datatype, which is better than nothing but less general and useful. It's like a reduce operation, where the left and right operations are the same type letting you do min, max, product etc. But if you're constrained to something so rigid, you can't express so many other things. Having records of data which travel together and get manipulated in a uniform way is a useful paradigm. Tables as a first class data structure or at least a convention understood by a large portion of your standard library, will get more adoption over time just as we have seen ideas like map and filter become common, even expected tools.
