  Sass Style Guide: A Sass Tutorial on How to Write Better CSS Code

Writing consistent and readable CSS that will scale well is a challenging process. Especially when the style sheets are getting larger, more complex, and harder to maintain. One of the tools available to developers to write better CSS are preprocessors. A preprocessor is a program that takes one type of data and converts it to another type of data, and in our case CSS preprocessors are preprocessing languages which are compiled to CSS. There are many CSS preprocessors that front-end develop...

  When and Where to Use Pointers in Go

When declaring variables in Go, we usually have two syntax options: In some scenarios, pointers; in others, reference; sometimes, either. It’s great to have choices, but it is also confusing sometimes as to which one in which scenario. To be more reasonable in choice-making, I started from pointers, walked through their natures, and summarized some rules in using them in Go. from unsplash, Jordan Ladikos Pointers Go has pointers. A pointer holds the memory address of a ...

  Your Code is My Hell

It occurred to me recently that my experience as a Rails developer may be somewhat unique.I often get brought in to help preexisting Ruby/Rails projects evolve and mature in a sustainable way. As a result, the vast majority of Ruby projects I’ve worked on have been well-established by the time I arrived. In fact, offhand I can only think of one commercial greenfield Ruby project I’ve participated in. All the rest have been “legacy” from my perspective, in the ...

  Address of a Java Object

In conventional java programming, you will never need address or location of a java object from memory. When you discuss about this in forums, the first question raised is why do you need to know the address of a java object? Its a valid question. But always, we reserve the right to experiment. Nothing is wrong in exploring uncharted areas.I thought of experimenting using a little known class from sun package. Unsafe is a class that belongs to sun.misc package. For some of you the package might ...

  What Can We Learn From Dennis Ritchie?

As we noted earlier this week, one of the founding fathers of UNIX and the creator of C, Dennis Ritchie, passed away last weekend. While I feel that many in computer science and related fields knew of Ritchie’s importance to the growth and development of, well, everything to do with computing, I think it’s valuable to look back at his accomplishments and place him high in the CS pantheon already populated by Lovelace, Turing, and (although this crowing will be controversial, at lea...

  Consistency between Redis Cache and SQL Database

Nowadays, Redis has become one of the most popular cache solution in the Internet industry. Although relational database systems (SQL) bring many awesome properties such as ACID, the performance of the database would degrade under high load in order to maintain these properties. In order to fix this problem, many companies & websites have decided to add a cache layer between the application layer (i.e., the backend code which handles the business logic) and the storage layer (i.e., the SQL d...

  How Query Optimizer Works in RDBMS

In a previous post, we discussed how the various relational operators are implemented in relational database systems. If you have read that post, you probably still remember that there are a few alternative implementations for every operator. Thus, how should RDBMS determine which algorithm (or implementation) to use? Obviously, to optimize the performance for any query, RDBMS has to select the correct the algorithm based on the query. It would not be desirable to always use the same algori...

  Go Error Best Practice

Being indulged in Go for quite a while and having implemented web-related programs, grpc interfaces and Operators, I seem to be an advanced beginner now. However, I am still a raw hand in production-environmental debugging, which is cumbersome if done by querying logs or error messages. Imagine the scenario that a full-text search is called when the specific location of the error log is missing. Then what happens when those error logs are not only in one place? Yes, my error logs can no longer h...
