B) Design principles. Many people have listed seven principles, such as single duty principle, opening and closing principle, Richter substitution principle, dependence inversion principle, interface isolation principle, composite reuse principle and Dimit principle. LSP, I elevated it to one of the three cornerstones of the object-oriented paradigm; Single responsibility and interface isolation are mainly used as the principle of responsibility division in object-oriented analysis/OOA, which you can not pay much attention to at this time. Relying on the inversion principle, I throw it away as garbage, because the opening and closing principle or directly "relying on abstract type principle" already contains the essence of relying on the inversion principle, while the dross of relying on the inversion principle is inherited by IoC. Of course, the pullback, I emphasize very much. Therefore, you need to master the abstract dependency principle (OCP), one-way dependency principle (including the learning of callbacks) and the minimum dependency principle (composite reuse principle, Dimit rule).
本片以一个住在佛寺中的9岁男孩的生活为背景，讲述了这样一个故事：在深山寺庙里，三名来自不同世代的僧人一起生活，其中一个充满幻想与童真的九岁的童僧Do-nyeom，自出生起就在这座寺苗里修炼，但面对着各种清规戒律却不断地与之冲突。
本剧以史实为依据，全方位展现了一段鲜为人知的历史：共和国领袖毛泽东和周恩来、聂荣臻等老一代领导人运筹帷幄，英明决策，钱学森、邓稼先等杰出科学家在极端困难的条件下，自主研制两弹一星，开创了中华民族屹立于世界东方的丰功伟业。全剧闪耀老一辈开国元勋的风采和爱国知识分子的光芒，唱响了一曲五星红旗迎风飘扬的艰苦奋斗、无私奉献的主旋律。本剧还以纪实的风格，全景式展现了从国事到家事、从事业到爱情、从领袖到元帅、从将军到士兵、从大科学家到普通技术员、从原子弹理论设计到技术上的难关和细节。
As for us, through a shortcut of knowledge, just a few days of experiences came to teach us these facts, that multiple species of plants can be used as dyes and that plants carry most of the pigments. However, most of these pigments are fragile and break down easy over time, or once the fabric is washed. Only pigments that well resist oxidation make up valuable dyes.
For codes of the same length, theoretically, the further the coding distance between any two categories, the stronger the error correction capability. Therefore, when the code length is small, the theoretical optimal code can be calculated according to this principle. However, it is difficult to effectively determine the optimal code when the code length is slightly larger. In fact, this is an NP-hard problem. However, we usually do not need to obtain theoretical optimal codes, because non-optimal codes can often produce good enough classifiers in practice. On the other hand, it is not that the better the theoretical properties of coding, the better the classification performance, because the machine learning problem involves many factors, such as dismantling multiple classes into two "class subsets", and the difficulty of distinguishing the two class subsets formed by different dismantling methods is often different, that is, the difficulty of the two classification problems caused by them is different. Therefore, one theory has a good quality of error correction, but it leads to a difficult coding for the two-classification problem, which is worse than the other theory, but it leads to a simpler coding for the two-classification problem, and it is hard to say which is better or weaker in the final performance of the model.
名为“战争灾难”的另一场战争——。
The reason why the film is attractive is that I personally think it cannot be separated from the large number of comparisons in the film, the dramatic conflicts arising from these, and the main actors involved in the film are full of passion and love for life, no matter how this emotion is finally expressed.
