  Use of log in programming

Usually, The purposes of log are for troubleshooting and displaying program running status. Good log will help us locate the error easier. Many programmers think log in programs is very simple, but it's not an easy task to write log codes to efficiently locate the error. Here we discuss about program log in three aspects: Where to log What to log Log styles to be avoided Where to log 1. When calling external functions When your program is calling some external functions which are not written b...

  Native Audio with HTML5

Once upon a time, audio on the web lived primarily in the world of third-party browser plug-ins like Flash, QuickTime and Silverlight. This was not a bad world, but it had its issues.For one, most plug-ins require the user to install them, but not all users are willing (or able) to install them. Also, many players built with these plug-ins are inaccessible, making it difficult for folks who use assistive technologies to access the audio or alternative content.Then there are the front-end design ...

  A plugin to update last_error in Delayed Job

delayed_job is a process based asynchronous task processing gem which can be ran at background. It will fork the specified number of processes to execute the tasks asynchronously. The task status is usually stored in the database so that it can be easily integrated into a Rails application where asynchronous job execution is desired. Normally when a job fails to execute or error occurs, it would save the error into the database with the column last_error. Ideally all these will be handled b...

  What's Wrong with the For Loop

Closures in Java are a hot topic of late. A few really smart people are drafting a proposal to add closures to a future version of the language. However, the proposed syntax and the linguistic addition are getting a lot of push back from many Java programmers. Today, Elliotte Rusty Harold posted his doubts about the merits of closures in Java. Specifically, he asks "Why Hate the for Loop?": I don’t know what it is some people have against for loops that they’re so eager to...

  Obviously Correct

What do automatic memory management, static types and purity have in common? They are methods which take advantage of the fact that we can make programs obviously correct (for some partial definition of correctness) upon visual inspection. Code using automatic memory management is obviously correct for a class of memory bugs. Code using static types is obviously correct for a class of type bugs. Code using purity (no mutable references or side effects) isobviously c...

  C++11 multithreading tutorial

The code for this tutorial is on GitHub: https://github.com/sol-prog/threads. In my previous tutorials I’ve presented some of the newest C++11 additions to the language: regular expressions, raw strings and lambdas. Perhaps one of the biggest change to the language is the addition of multithreading support. Before C++11, it was possible to target multicore computers using OS facilities (pthreads on Unix like systems) or libraries like OpenMP and MPI. This tutorial is meant to get you st...

  5 Reasons Your Javascript Stinks

Javascript gets a bad rap on the Internet, but there are few languages that are so dynamic, so widespread, and so deeply rooted in our lives as Javascript is. The low barrier of entry leads some people to call it a script kiddie language, others scoff at the concept of a dynamic language while riding their statically typed high horse. You and Javascript just got off on the wrong foot, and now you've made it angry. Here's five reasons why your Javascript code sucks.1. You're not using a namespace...
