As Richard Feynman said, no one really understands quantum mechanics. I have done a lot of research work for writing this article, and I hope it could give you a head start to explore the amazing quantum world. But if you find it hard to understand, well, that is normal. I also found quantum theory weird and hard to believe.
You may have heard that quantum computers are fast. Yes, they are fast. Months ago, Google’s quantum computer has proven that it can solve certain types of problems 1.5 billion times faster than the top supercomputer on Earth. But the interesting thing about quantum computers is that they are not just fast. They behave the same way as described in quantum theory that you will see below and that makes it fundamentally different than a classical computer. …
At first, Oracle Cloud Free Tier seems to be slightly better than other competitors. They let you use 2 VMs of 1/8th of OCPU, 1 GB memory and 50 GB HDD each. This is
VM.Standard.E2.1.Micro instance and is supposed to be free forever.
So I created a trial account, input my credit card information, and went straight to create a new VM.
Out of host capacity
This was what I got when I clicked the “Create” button. I tried again for a hundred times, same result.
The next thing I tried was to ask for support from Oracle. My Oracle Support seemed to be the one I needed. But no, there is nothing about “Out of host capacity”. …
Every programming language has one or more coding style guidelines. All developers know that but some of them don’t care. They practice bad programming habits for years without realizing the importance of the issues they caused.
As one of the hiring managers at Zuhlke Hong Kong, I’ve seen a lot of code smells during coding interviews. Here are the top 16 bad coding practices organized into 6 categories: coding style, dirty code, testing, error handling, code complexity, and optimization.
Murphy’s law states that,
Anything that can go wrong will go…
