As you can see, calculations of 4 × 3 and 6 × 2 are not necessary. Therefore, we only need to consider factors up to √n because, if n is divisible by some number p, then n = p × q and since p ≤ q, we could derive that p ≤ √n.

Readability. Not everyone has screens and printers that make it easy to distinguish all characters. We easily confuse similarly spelled and slightly misspelled words.
"Aapo did it again!" - I exclaimed while reading this paper yesterday on the train back home (or at least I thought I was going home until I realised I was sitting on the wrong train the whole time. This gave me a couple more hours to think while traveling on a variety of long-distance buses...)

Web3 社区对于非同质化带币（NFT）充满了期待。尽管还没有杀手级应用的出现，但是这项技术已经重塑了数字资产所有权，身份体系，创新范式和社区运作方式。因为 NFT 是可以被买卖交易的数字资产，而 NFT 交易所收集了 NFT 的信息并且撮合了买家和卖家，所以 NFT 交易所是生态中一个必不可少的部分
本文主要介绍了一种人群行为分类数据库 Crowd-11，它包含 6000 多个视频序列，每个序列平均包含 100 帧。该数据库旨在对细粒度人群行为进行分析。研究人员开发了三种学习方法：1）Group Profiling Descriptors，通过分析人群组成和运动模式进行人群行为分类；2）Two-stream architecture，通过结合运动和外观信息进行人群行为分类；3）C3D，利用 3D 卷积神经网络进行人群行为分类。这些方法在 Crowd-11 数据库上进行测试，并在多种指标上取得了良好的性能。

事情是这样的，前几天电脑崩溃，硬盘数据全部丢失，重装系统和Xcode之后，从Develop Center的Certificates里重新下载证书，安装到新电脑上，在真机上运行时，提示报错:”A valid signing identity matching this profile could not be found in your keychain”, 按照字面意思查了一下，是因为本地KeyChain里丢失了private key的缘故，得到的结论是要么从之前的备份中恢复，或者重新生成新的证书。遗憾的是我之前并没有保存备份，无奈只好重新生成。一个问题马上出现在脑海，就是重新生成新的证书是否会对线上的App产生影响。查了一下官方的文档，发现有这部分详细的说明，消除了我的顾虑，内容如下(参考2)：

Clarity. A function with a not_null<T> parameter makes it clear that the caller of the function is responsible for any nullptr checks that may be necessary. Similarly, a function with a return value of not_null<T> makes it clear that the caller of the function does not need to check for nullptr.

With Network Address Translation (NAT), IP addresses are mapped from one realm to another, in an attempt to provide transparent routing to hosts. Traditionally, NAT devices are used to connect an isolated address realm with private unregistered addresses to an external realm with globally unique registered addresses. There are many variations of address translation. For the project, you are going to implement Basic NAT [4].
