  Strict mode in JavaScript

1. Introduction In addition to normal mode, ECMAScript 5 includes the other mode : strict mode. It means it will make JavaScript codes execute in a more strict environment. The purposes to have strict mode are: Remove some unreasonable and parts of JavaScript syntax. Reduce some of the quirk behaviors. Remove some insecure parts of code execution. Make the execution environment more secure Improve interpret efficiency and increase the execution speed Build foundation for future JavaScript versi...

  Why Lua

In this article, I would like to discuss why you should use Lua. This all started with a message that recently popped up on the Lua mailing list regarding why isn't Lua more widely used? The answers went from randomness to lack of libraries to a variety of other things, but the one that resonated with me most was that there are fewer people who enjoy the do it yourself approach, which Lua fully embraces. I've come to think of Lua as the Arch Linux of programming languages. Which, almost by d...

  One thought about JavaScript exception handle

Due to network, browser and cache issues, the JS executed in production may produce different results from the testing environments. Sometimes they may produce exceptions. Front-end developers may encounter this kind of exceptions frequently. But how to log and use them is seldomly considered by them. Actually, exception handling includes two steps : log and use. 1. Log Regarding to log error, this is relatively convenient, since in each browser, there is one interface called window.onerror. win...

  Why I love everything you hate about Java

If you’re one of those hipster programmers who loves Clojure, Ruby, Scala, Erlang, or whatever, you probably deeply loathe Java and all of its giant configuration files and bloated APIs of AbstractFactoryFactoryInterfaces. I used to hate all that stuff too. But you know what? After working for all these months on these huge pieces of Twitter infrastructure I’ve started to love the AbstractFactoryFactories. Let me explain why. Consider this little Scala program. It uses â€...

  Top 10 Go Coding Traps and Tips

Go is currently the most common programming language in cloud development. Though I use it very much in my work, I am still repeating certain mistakes. This article is more a record of these errors, figuring out the causes and solutions so that people who read this article will save themselves time when coming across the same problems. Let’s cut through to the tips. Don’t rely on index var in the for loop The most common mistake we make is that we often create goroutine&nbs...

  Fujitsu CTO: Flash is just a stopgap

Flash is a necessary waystation as we travel to a single in-memory storage architecture. That's the view from a Fujitsu chief technology officer's office. Dr Joseph Reger, CTO at Fujitsu Technology Solutions, is that office-holder, and – according to him – flash is beset with problems that will become unsolvable. He says we are seeing increases in flash density at the expense of our ability to read and write data. Each shrink in process geometry, from 3X to 2X and onto 1X, ...

  That “JavaScript not available” case

During some interesting discussions on Twitter yesterday I found that there is now more than ever a confusion about JavaScript dependence in web applications and web sites. This is a never ending story but it seems to me to flare up ever time our browsing technology leaps forward. I encountered this for the first time back in the days of DHTML. We pushed browsers to their limits with our lovely animated menus and 3D logos (something we of course learned not to do again, right?) and we were ...

  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...

  Programming Languages for Machine Learning Implementations

Machine learning algorithms have a much better chance of being widely adopted if they are implemented in some easy-to-use code. There are several important concerns associated with machine learning which stress programming languages on the ease-of-use vs. speed frontier.Speed The rate at which data sources are growing seems to be outstripping the rate at which computational power is growing, so it is important that we be able to eak out every bit of computational power. Garbage collected la...
