Back and forth in time geeks bought a few courses, but also to learn about it. My personal feeling is that these courses do not count, do not expect after learning there is a qualitative leap. And, frankly, these courses are mostly small dry goods itself, not a system that allows up to such a point that you have a sense of some idea, or have your own needs such as reading, more practice to study in depth the job. Of course, some of these courses for a certain amount of knowledge in order, you can go to learn on topics you're interested in, feel the significance of these courses will only be the case.
But, nevertheless, on the whole still a little meaning, first of all it is not expensive. Furthermore, we do not expect you to spend much money, how much money will certainly value to be obtained, may sometimes courses in the sentence, an idea you think this money worth it.
So, what I feel is worthwhile to buy this lesson does not exist.
Here is what I bought several courses in Geek:
A web protocol detailed packet capture and combat
Had to buy this is to learn to use at wireshark capture, see course descriptions feeling a lot of things. After buying found that most of this course is some conceptual stuff
Moreover, the capture explanation is not very detailed, mostly a passing. If you want to know http / 1.1, http / 2, websocket, tls / ssl, tcp / ip and so some of the
things you can look down, then targeted learning
How to design a system of two spike
The architectural design of the spike explain a bit, and spike scene common design methods, such as static and dynamic separation, caching hot data, such as traffic clipping. This course provides some ideas on a concurrent reduction of inventory design, my personal feeling good
Overall, this course used to explore ideas under it.
US third data structures and algorithms of
Buy this course, but also want to learn the next algorithm, because I almost never learned arithmetic before, the main work is rarely in contact. But later found that although used much, but if you want to learn some good points of the project or program to write more optimized,
the algorithm is very important.
This course I feel good, he not only talked about common data structure, stacks, queues, trees, graphs, etc., but also some scenes of these structures also talked about. In addition, the festival say that recursion is very good, not to analyze recursive program recursion in their minds, otherwise, your brain capacity is not enough, ha ha.
还讲了缓存的实现用到的数据结构，搜索引擎用到的结构，高性能队列，微服务鉴权限流等算法，海量数据查数据等，
想学算法的，这门课真的不错
四 技术管理36讲
上家公司转了管理，然后看到极客上有这门课就买了。这门课如果想转管理的开发人员拿来读读也不错，有些针对初入管理的开发人员的一些迷茫和应对方法。
不过，我感觉还是没有解决我的问题，就是在开发还是管理的选择上，一直犹豫不决。
五 邱岳的产品实战
开发还是要有点产品思维，即使不转产品， 这个除了拿来怼产品外 ，对产品需求评审，用户需求，什么是一个好产品，如何实现产品增长等可以丰富你的阅历
六 趣谈网络协议
对网络的原理讲解的还不错，平时用到的，但不会去想那么多，通过这些讲解，让你理解的更深层了。比如那个如果国外的网络，拿到中国，有没有翻墙的限制？手机是如何上网的等
七 从0开始学架构
大多概念性的术语，对如何实现高性能，高并发，高可用等提供了一些思路，讲解了微服务和一些分布式的东西，这个算是初级架构吧，入个门看看也不错，想深入就自已再找书学了
Ps: 我发这些是因为以前放了数据结构那个二维码出去有好几个月了，我后面就没管了，昨晚有两个人通过那个链接还购买了课程，所以就想把我买的这些课发出来，如果有需要的朋友通过这个购买，双方都能实惠，何乐而不为呢？
另外，我打算买那个丁奇的mysql课程，如果有那位朋友买了，欢迎留言区来个二维码，嘿嘿。
