Can two new objects point to the same memory address in GoLang?
Do you have any idea what the output will be for below GoLang snippet? package main import ( "fmt" ) type obj struct{} func main() { a := &obj{} fmt.Printf("%p\n", a) c := &obj{} fmt.Printf("%p\n", c) fmt.Println(a == c) } Many people would think that a and c are two different object instances which have different memory addresses. Hence a == c will be false. But if you try to run the above program, you would see below output 0x5781c8 0x5781c8 true To get to know the reason wh...

Is Facebook becoming Tencent like?
Recently there is news that Facebook is developing a Reader application which is to compete with Flipboard and Pulse. This reminds me a few movements of Facebook in the past few months. First they built a copy of Snapchat named Poke which failed badly at last. Then they launched a new feature on Instagram named Video on Instagram which allows users to shoot and share short videos up to 15 seconds. This feature is to compete with Vine from Twitter. It seems Instagram wins over Vine on this. You c...
Spurring the Consumer Feedback Loop with Connected Devices
In a press release from earlier this year, Gartner had predicted that by the year 2018 mobile devices would account for initiating 5% of consumer services cases, registering a marginal rise of 0.02% from 2014. Research shows that most businesses lose around a whopping $83 billion owing to poor consumer services (Source: kissmetrics) in the US alone while globally, the average cost of losing a consumer is $243. It is only viable to think of automating support services as a way to lower the costs ...

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’...

How GitHub Works: Be Asynchronous
This is — by far — my favorite aspect of working at GitHub. Everything is asynchronous. Chat GitHub didn’t have an office for the first two years. Chat rooms (in our case, Campfire) is where things got done. Today we’ve moved into our second office, and Campfire is still where we get things done. There’s a reason for that: chat is asynchronous. Asynchronous communication means I can take a step out for lunch and catch up on transcripts when I get back. Async...

How key-based cache expiration works
There are only two hard things in Computer Science: cache invalidation and naming things — Phil Karlton Doing cache invalidation by hand is an incredibly frustrating and error-prone process. You’re very likely to forget a spot and let stale data get served. That’s enough to turn most people off russian-doll caching structures, like the one we’re using for Basecamp Next. Thankfully there’s a better way. A much better way. It’s called key-based cac...

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...

A C++ program puzzle
Recently I came across a question asked by wang2191195 on a Chinese IT forum CSDN which asks about a C++ program puzzle. He has a code snippet which cannot be compiled. The code is:#include <cstdlib> #include <iostream> using namespace std; class Base{ public: virtual void func(){ cout << "Base::func()" << endl; } virtual int func( int num ){ cout << "Base::func( int " << num << " )" << endl; return 0; ...
