  Text editor vs IDE


A meaningless editor war Many people like to debate which editor is the best. The biggest controversy is between Emacs and vi. vi supporters like to say: "Look it's very fast to type in vi, our fingers no need to leave the keyboard, we even no need to use the up,down,left and right keys" Emacs supporters often downplayed this and said: "What's the use of typing fast if I just need to press one key and it equals to dozens keys you type in vi?"In fact, there is another group of people who like to ...

  mysql – connection example


Mysql is a database, and to gain access to the data within C++ you will need to be able to “talk” to the database via queries (just like on the mysql command line interface e.g. select * from tablename), the connection process is very similar to the command line interface you will need to supply connection details as in hostname (localhost normally), username, password, database to use and also there are other details that you can pass e.g port number more information can be gained from the ...

  Create cron job on CentOS


These two days, I am building a website and deploying it on a VPS server which uses CentOS 5. I don't have cPanel or Plesk for my account, so I need to install and configure everything myself including Apache, PHP, MySQL and FTP server, also today's topic cron job. Since my website has a ranking algorithm to calculate the rankings of each link and update the ranking on database and I need to calculate the rankings every 5 minutes, so I think to use cron jobs. Here are what I have done which may ...

  Why Only Designers Can Create New Programming Languages


Attempts to verify the utility of languages stifle innovation. Christopher Mims 03/06/2012 30 Comments Compared to the versions that are hacked together late at night under insane deadline pressure, the programming languages to come out of academia are failures. Well, not all of them. History can speak for itself. Via UC Irvine computer scientist Cristina Videira Lopes, who deserves credit for any insight you might get from this post, which is a ...

  printf("goodbye, Dennis");


Dennis Ritchie, a father of modern computing, died on October 8th, aged 70EVERY time you tap an iSomething, you are touching a little piece of Steve Jobs. His singular vision shaped the products Apple has conjured up, especially over the last 14 years, after Jobs returned to the helm of the company he had founded. Jobs's death in October resembled the passing of a major religious figure. But all of his technological miracles, along with a billion others sold by Apple's competitors, would be mere...

  Emacs adventures


I have been using Emacs for over a year now. I actually didn’t learn a lot when I started using it (just the basics to get going and then some relatively common keyboard shortcuts), but lately I have been reading and learning much more about it. I’m so grateful by everything I’ve learned from different people on the net that I wanted to share a couple of things I’ve learned, and a simple major mode for editing AsciiDoc documents. As a long-time VIM user, I feel it’s my duty t...

  How I Became a Programmer


I posted a very brief response to a post on HackerNews yesterday challenging the notion that 8 weeks of guided tutelage on Ruby on Rails is not going to produce someone who you might consider a "junior RoR developer." It did not garner many upvotes so I figured that like most conversation on the Internet it faded into the general ambient chatter. Imagine my surprise when I woke up to couple handfuls' worth of emails from around the world asking me what I did, how I did it, an...
