  How NOT to teach a computer language

For the past year or so my wife has been taking online classes to get a computer science degree. For most of her classes she’s done great, she’s been flying through HTML and SQL, even up to the point where she can handle multilevel joins and optimizing through indexes. That was until she hit her vb.net class. I had no idea why she was having problems with a language has easy as vb.net so I started helping her out and find out why she was having so many problems. I’ve also ad...

  Understanding GoLang interface

If goroutine and channel are considered as the foundation for GoLang concurrency, interface would be the key for data types in GoLang. In practical Go programming, almost all data types are built/used around interfaces, interface is the core of GoLang data structures. Go is not a typical OOP language, it has no class and inheritance concept syntactically. But it doesn't mean that there cannot be polymorphism in GoLang. Because of interface, it achieves the same polymorphism effect as in C++, tho...

  A Toast to C

At Cloudmetrx, we use a lot of C. So given the recent passing of UNIX legend Dennis Ritchie, the creator of the C language, we think a toast to C is only fitting.Our extensive reliance on C is especially unusual considering the other languages in our stack – Clojure, Node.js, and other hipster platforms. We aren't predisposed to using older, "venerated" technologies simply because they're older and venerated. But when it comes to high-performant computation, there's just nothing like C. S...

  An experience of fixing a memory-corruption bug

During the last 4 months, I was disturbed by a memory-corruption bug, and this bug will cause program crash. Until last Monday, I found the root cause and fixed it. This debug process is a difficult but memorable experience, so I will share it in this article.   My program works as a SMS Hub. When it receives a SMS, it will allocate a structure in heap memory like this: typedef struct { ...... int *a[8]; ...... } info; After processing the SMS, the program will free the m...

  Fix issue "cannot load such file -- bcrypt_ext (LoadError)"

bcrypt() is a sophisticated and secure hash algorithm designed by The OpenBSD project for hashing passwords. The bcrypt Ruby gem provides a simple wrapper for safely handling passwords. However, sometimes the rails application would fail to start after installing the bcrypt gem on Windows. The error would look similar to below.

  It Should Only Take You a Few Hours...

It sure seems easy to make a table. Anyone can do it, right? Get 1 large flat rectangular piece of wood, 4 equally tall wooden poles, 4 nails and a hammer. Nail the 4 poles to each corner of the flat rectangular bit, and you have a table. Ta daaa! Now ask a carpenter to craft you a table. First they will spend time discussing the purpose and function of the table - indoor or outdoor, kitchen or dining room, for show or heavy use, what load does it need to bear. Then they will determine th...

  Round Peg, Square Hole: How to Know If a Developer is a Good Fit for Your Team

Over the last few months, we have been recruiting developers, and we’ve started to get a sense for the type of developer who is a good fit for our team.  These attributes probably apply for developers at most web startups, so I wanted to share them with you. Before I get into it, the most important thing to know is that technical skill is a threshold requirement.  The assumption is that any person who is a fit for our team will have the relevant technical experience t...

  Why I love Common Lisp and hate Java

“Common what?” is a common reply I get when I mention Common Lisp. Perhaps rightly so, since Common Lisp is not all that common these days. Developed in the sixties, it is one of the oldest programming languages out there. In its heydays it was used mostly for Artificial Intelligence research at MIT, Stanford, Carnegie Mellon and the like, and therefore has a lingering association with AI. People not in AI shy away from Lisp. Common Lisp is a powerful and versatile program...
