Performance comparison of string concatenation in Go language
In Go language, string concatenation is an inevitable operation during development, and efficient string concatenation is crucial for improving application performance. This article will delve into several common ways of string concatenation, provide performance comparisons, and offer optimization suggestions aimed at helping developers write more efficient code. Common ways of string concatenation In Go language, common ways of string concatenation include the following: Using the + operator fo...

How much money do you *really* need to start your company?
I keep hearing startup entrepreneurs tell me “We need funding. If we just had $XXXk of investment, we’d be killing it right now.†I press them with one question: what would you do with the money if you had it? Inevitably the question is met with a blank stare. Most of the time people haven’t thought about it. The answers that do come feel a little half-baked:“Buy a bunch of ad words to get people to our site – that’s all we needâ€â€œBuild th...

Here Are The 10 Highest-Paying Jobs At Google
South African job listing site JobVine compiled the following chart of the top ten salaries at Google, compiled from Glassdoor.The top pay is for contract positions leading software development. It's not uncommon to see contractors earn more salary than full-time employees at big tech companies, because they're often not able to get stock options and perks.For jobs within the company, it looks like directors of product management are the highest paid, which is fitting with Google's new...

Debunking the Google Interview Myth
Years ago, rumors used to circulate about Microsoft interviews. They were the hot, new company that everyone wanted to work. With envy came the urban myths. These rumors have since been transfered to Google, and will surely be transfered to some new company in due time. Bloggers – always desperate for links and traffic – have capitalized on this, with scary articles about their “nightmare interview†and “crazy questions“. Let’...

new expression vs operator new in C++
In C++, there is a new mechanism for memory allocation and management. When we want to initialize an object, we can use new expression to get enough memory for storing an object and also initialize the object. When we want to create a new object, we can use new expression, for example: Obj *obj=new Obj; Basically, what the new expression does is to allocate enough memory for storing the obj object, in addition, it will initialize the object with some intial values. Also, there is an operator new...

Obviously Correct
What do automatic memory management, static types and purity have in common? They are methods which take advantage of the fact that we can make programs obviously correct (for some partial definition of correctness) upon visual inspection. Code using automatic memory management is obviously correct for a class of memory bugs. Code using static types is obviously correct for a class of type bugs. Code using purity (no mutable references or side effects) isobviously c...

What I learned from a month of blogging and 250k visits
Roughly a month ago, I decided to give blogging another try, in earnest. I put out an article most days and up to 3 per day when I was experimenting with new channels.It has been fascinating.That being said, this is not a post about blogging tactics. It’s about what the experience has taught me about startups.Find the customers first, then build for themIt took me a long time to understand YC’s motto that you should:Make something people want.The first time I heard that, ...
Polymorphism in OOP programming
Polymorphism is the capability of an action or method to do different things based on the object that it is acting upon. This is the third basic principle of object oriented programming. Overloading, overriding and dynamic method binding are three types of polymorphism. Overloaded methods are methods with the same name signature but either a different number of parameters or different types in the parameter list. For example 'spinning' a num...

Find the kth smallest number in an array
This is an classical question, the general solution to this question is first using sorting algorithm to sort the array, then get the kth number in the array, the complexity is O(nlogn), we can also use selective sort or head sort to, the complexity of selective sort is O(kn) and heap sort is O(nlogk). The better solution is to use quick sort to find the kth smallest number, the complexity is O(n), the worst case cost is O(n^2). But today we introduce one more solution which has the worst case c...
