1. Parenting does not appear to be able to determine the personality traits of a child.
2. When the last ice age ended, 12,000 years ago, the Sahara was green and full of life. It turned into a desert about 5,500 years ago.
3. Fadnes et al. claim that the UK population could live 10 years older if it changed its eating habits.
4. By studying 175 different populations, You et al. find that meat intake predicts longevity: people who eat more meat live longer.
5. According to an editorial in the journal Nature, scientists who work in industry are more satisfied and better paid than are colleagues in academia. Industry scientists report less bullying and discrimination.
6. The Asch experiment examined the extent to which individuals would conform to the majority view, even when that view was clearly incorrect. The experiment involved a group of participants, one of whom was the actual subject of the experiment, and the rest were people who knew the true purpose of the experiment and acted according to a script. The group was shown a series of images with lines of different lengths and asked to identify which two lines were the same length. The results showed that a significant number of participants conformed to the majority view, even when it was clearly wrong. The Asch experiment is important because it highlights the influence of social factors on individual beliefs. Most people just adopt the prevaling beliefs, even when they are clearly incorrect. In other words, very few people can think for themselves. They just reproduce what they are shown or what they see others doing, like mere monkeys. Unfortunately, the original experiment is robust with respect to replication. We also find that even financial incentive fail to make people more critical.
7. Weather prediction is one of the first application of powerful computers. To this day, we rely on predictions made by specialized services: we don’t generally compute our own weather predictions. Google Deepmind claims to be able to predict the weather accurately on a normal computer using artificial intelligence.

VIPT 与缓存大小和页表大小的关系
VIPT（Virtual Index Physical Tag）是 L1 数据缓存常用的技术，利用了虚拟地址和物理地址的 Index 相同的特性，得以优化 L1 数据缓存的读取。但是 VIPT 的使用，与页表大小和 L1 数据缓存大小都有关系。这篇博客探讨一下，VIPT 技术背后的一些问题。

反向代理的 Partial Transfer 问题
反向代理已经是无处不在，但是如果反向代理没有根据使用场景调优，或者出现了一些异常，可能会带来不好的用户体验，并且现象十分奇怪，例如访问某 GitLab 实例的时候，偶尔会出现页面加载不完整的情况。
这些问题困扰了我们很久，到最后才发现，原来问题在反向代理上。下面就来回顾一下事情的经过。
