  Lasagna Code


Anyone who claims to be even remotely versed in computer science knows what “spaghetti code” is. That type of code still sadly exists. But today we also have, for lack of a better term — and sticking to the pasta metaphor — “lasagna code”.Lasagna Code is layer upon layer of abstractions, objects and other meaningless misdirections that result in bloated, hard to maintain code all in the name of “clarity”. It drives me nuts to see how badly some code today is. And then you come ac...

  A Month With Scala


Although I’ve played around with Scala for the few months, these efforts largely involved simple scripts and casual reading. It wasn’t until last month that the opportunity to use Scala in a large scale project finally arose and I dove right in. The project was a typical REST based web service built on top of Amazon’s Elastic Beanstalk, SimpleDB, S3 and Redis*. First off let’s talk about why I chose Scala in the first place. After spending a good deal of my last year entrenched in...

  Faster than C


Judging the performance of programming languages, usually C is called the leader, though Fortran is often faster. New programming languages commonly use C as their reference and they are really proud to be only so much slower than C. Few language designer try to beat C. What does it take for a language to be faster than C? Better Aliasing Information Aliasing describes the fact that two references might point to the same memory location. For example, consider the canonical memory copy: void...

  Use progressive JPEG to improve user experience


JPEG image files can have two different save types : Baseline JPEG and Progressive JPEG. Both of them have the same extension name but with different display effect. Baseline JPEG This type of JPEG files are scanned from top to bottom consecutively, each line of the image data will be saved sequentially. When opening this kind of images, data will be displayed with the save order line by line until all the data are read. If the image size is very large or network speed is very slow, the image wi...

  How to secure an Ubuntu Apache web server


Securing server software is not a straightforward task. Not all of our operating environments are the same, leading to a variety of potential security vulnerabilities. However, using a few basic configuration and security options, you can stay a little ahead of where you want to be. 1. Fail2ban Fail2ban is a Python-based intrusion prevention software that detects and blocks malicious IP addresses from multiple unsuccessful attempts at software logins. In other words, if someone is attempt...

  Functional Programming Is Hard, That's Why It's Good


Odds are, you don’t use a functional programming language every day. You probably aren’t getting paid to write code in Scala, Haskell, Erlang, F#, or a Lisp Dialect. The vast majority of people in the industry use OO languages like Python, Ruby, Java or C#–and they’re happy with them. Sure, they might occasionally use a “functional feature” like “blocks” now and then, but they aren’t writing functional code.And yet, for years we’ve been told that functional languages are awes...

  Building an iPhone application.


One of my New Years resolutions was to finally learn the iOS SDK and build a 'real' application.I am happy to report that progress is going really well and wanted to share something that I have noticed about iOS programming.It only looks scary... it's not. It's actually very easy.Now, I am not building Mail, Angry Birds or Photosynth or anything, but the core concepts of the SDK are not that bad once you spend some time learning delegation. If you don't understand delegation, iOS programmi...

  Beauty of front end--List of front end tools used by GitHub


I did this summarization when I added Lirate_CoffeeScript support for GitHub-Linguist, i.e how does GitHub do Marjdown render and code highlight in its front end. Lots of font end tools used by GitHub are open sourced. They are: 1. HTML/CSS/JavaScript 1.1 HTML template GitHub markup and template styleguide : https://github.com/styleguide/templates 1.2 Style and CSS GitHub uses replacement of CSS: SCSS:https://github.com/nex3/sass KSS:https://github.com/kneath/kss GitHub CSS styleguide : http...

  TIOBE: PHP is coming back


TIOBE released the programming language index for July 2013. The highlight of this month is that PHP is coming back. It ranks the fifth and has an increase of 1.54% compared to January. There are no changes in the ranking for the top 4 languages. The reason why PHP is back may be attributed to the new PHP Zend Framework that was released in September 2012, but this reason is not very convincing.

  How I Learned to Program


Programming is, without a doubt, the most mentally rewarding thing I've ever done. Programming taught me that life should be fun, filled with creativity, and lived to the fullest. Programming taught me that anything is possible; I can do anything I want using only my mind. Programming also taught me that learning is fun. It showed me that the more you know, the more power you have. Programming showed me that a life filled with learning is a life worth living. Programming revealed to me wh...
