What is cache penetration, cache breakdown and cache avalanche?
When designing and developing highly available system, cache is an very important consideration. It is useful to cache some frequently accessed data so that they can be accessed quickly and also cache can protect the downstream system like DB from being hit too often. To provide better cache design in large systems, some problems may need to be considered first. In this post, we will talk about some frequently discussed cache problems and mitigation plans.

Understand more about Go basics with one interview question
First, let's take a look at below Go interview question: package main const s = "Go101.org" // len(s) == 9 // 1 << 9 == 512 // 512 / 128 == 4 var a byte = 1 << len(s) / 128 var b byte = 1 << len(s[:]) / 128 func main() { println(a, b) } What would be the output in your mind? The output would be 4 0. Surprising? Before getting to the output values, some concepts in Go need to be introduced and explained in more detail. len() len() is a built-in function in Go to get t...

Some frequently used ES6 code snippets
Below are a list of ES6 code snippets which are used frequently. Hope that it will be helpful. 1. Shuffle array elements let arr = [67, true, false, '55'] arr = arr.sort(() => 0.5 - Math.random()) console.log(arr) // [ '55', 67, false, true ] 2. Remove characters which are not numbers const str = 'xieyezi 23213 is 95994 so hansome 223333' const numbers = str.replace(/\D/g, '') console.log(numbers) // 2321395994223333 3. Reverse sequence or words const sentence = 'xieyezi js so handsome, lol.'...

Pay Your Programmers $200/hour
If you are hiring programmers, you should pay them $200/hr. This breaks through otherwise impenetrable psychological barriers, helps solve the agency problem, and ensures you are only hiring programmers when you really need them. Expectations $200/hr is an open declaration of your expectations. It states that you are expecting to hire both a professional and an expert in the field. As a programmer, I treat contracts that pay me $200/hr differently from jobs/contracts that pay me $65/hr eq...

The Go Pointer Magic
Go is a language with the pointer type, by which we can Pass pointer into a function and update value in-place. Add methods to a struct as (* T) A, which is different from (T) A(). However, the pointer is type-safe in Go, meaning that there are such restrictions of the pointer. Different types of pointers are unconvertible. Pointer type cannot be used for calculation. Pointer types cannot be compared, either == nor !=. No mutual assignment between different pointer-...
RAM is the new disk...
Jim Gray, a man who has contributed greatly to technology over the past 40 years, is credited with saying that memory is the new disk and disk is the new tape. With the proliferation of "real-time" web applications and systems that require massive scalability, how are hardware and software relating to this meme? Tim Bray, in his discussions about grid computing before it became such a hot topic, pointed out how advances in hardware around RAM and networking were allowing for the creation...
Code coverage rate
When doing unit testing, the code coverage rate is often used as the criteria for measuring testing performance, even in some cases code coverage may be used to consider whether the testing task is completed or not. So testers need to spend much time on designing test cases which can cover as many codes as possible. There are advantages and disadvantages about using code coverage rate. First let's check what is code coverage rate: code coverage rate= the degree of code coverage in testing. There...
