  The "C is Efficient" Language Fallacy

I came across an article yesterday about programming languages, which hit on one of my major peeves, so I can't resist responding. The article is at greythumb.org, and it's called Programmer's rant: what should and should not be added to C/C++. It's a variation on the extremely common belief that C and C++ are the best languages to use when you need code to run fast. They're not. They're good at things that need to get very close to the hardware - not in the efficiency sense, but in the...

  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 ...

  Why Good Programmers Are Lazy and Dumb

I realized that, paradoxically enough, good programmers need to be both lazy and dumb. Lazy, because only lazy programmers will want to write the kind of tools that might replace them in the end. Lazy, because only a lazy programmer will avoid writing monotonous, repetitive code – thus avoiding redundancy, the enemy of software maintenance and flexible refactoring. Mostly, the tools and processes that come out of this endeavor fired by laziness will speed up the production. This ma...

  The mystery of Duqu Framework solved

The Quest for Identification In my previous blogpost about the Duqu Framework, I described one of the biggest remaining mysteries about Duqu – the oddities of the C&C communications module which appears to have been written in a different language than the rest of the Duqu code. As technical experts, we found this question very interesting and puzzling and we wanted to share it with the community. The feedback we received exceeded our wildest expectations. We got more than 200...

  Are older people better programmers?

Peter Knego states something interesting: “It's official: developers get better with age. And scarcer.”. He uses reputation and other metrics from StackOverflow to corroborate his point. His summary is: Number of coders drops significantly with age. Top developer numbers, at age 27, drop by half every 6-7 years.Developers in their 40s answer roughly twice as much and ask half the questions compared to colleagues in their 20s. It seems younger generation learns and older generatio...

  Scala Macros

This is the home page of project Kepler, an ongoing effort towards bringing compile-time metaprogramming to Scala. Our flavor of macros is reminiscent of Lisp macros, adapted to incorporate type safety and rich syntax. Unlike infamous C/C++ preprocessor macros, Scala macros: 1) are written in full-fledged Scala, 2) work with expression trees, not with raw strings, 3) cannot change syntax of Scala. You can learn more about our vision of metaprogramming from our talks. We propose to enrich Scala ...

  Some geek mats to welcome guests

Geeks are mostly otaku, they like surfing the Internet, playing games. Perhaps not everyone is a programmer, but most of them have some understanding of programming. It is undoubtedly very necessary to have a specific pattern mat at the door as a glorious proud geek, what mat should you use? 1. Binary Floor/Door Mat There are 10 kinds of people in the world, one is understanding binary code, the other one who doesn't understand binary code. The above binary mat is the binary codes of " welcome"...

  10 Object Oriented Design principles Java programmer should know

Object Oriented Design Principles are core of OOPS programming but I have seen most of Java programmer chasing design patterns like Singleton pattern , Decorator pattern or Observer pattern but not putting enough attention on Object oriented analysis and design or following these design principles. I have regularly seen Java programmers and developers of various experience level who either doesn't heard about these OOPS and SOLID design principle or simply doesn't know what benefits a particular...

  Test-Driven Development? Give me a break...

Update: At the bottom of this post, I've linked to two large and quite different discussions of this post, both of which are worth reading... Update 2: If the contents of this post make you angry, okay. It was written somewhat brashly. But, if the title alone makes you angry, and you decide this is an article about "Why Testing Code Sucks" without having read it, you've missed the point. Or I explained it badly :-)Some things programmers say can be massive red flags. When I h...

  Why MySQL 8 drops support of query cache

Many of you may have heard or used MySQL's query cache, because it used to be a popular way to improve MySQL's performance. As an important feature for improving MySQL's performance, the query cache was often recommended as a solution for slow queries. However, why has MySQL 8 abandoned the query cache? Today, we will analyze and explore this decision. What is query cache? According to official document: The query cache stores the text of a SELECT statement together with the correspon...
