  10 Reasons Why Visual Basic is Better Than C#

Visual Basic is a better programming language than Visual C#. Who says so? This article! Here are 10 reasons why you should always choose VB over C#. 1 – “Rose is a rose is a rose is a rose” This is a quotation from Gertrude Stein’s 1922 play Geography and Plays. However, the poetry wouldn’t work in C#, because – unforgivably – it’s a cASe-SeNSitIvE language. This is madness! Before I start ranting, let me just acknowledge that case-sens...

  Create Packed Indexes with MySQL

I am pretty much sure that you are aware of indexes which we are creating on database fields. Indexes are very useful to make your query search faster and improve the site performance. But the fact is that Indexes which we are creating on database tables also require some additional space on your hard disk and if you have not properly created these indexes than some t...

  SSH Security and You - /bin/false is *not* security

Backstory While at RIT around 2004 or 2005, I discovered that a few important machines at the datacenter allowed all students, faculty, and staff to authenticate against them via ssh. Everyone's shells appear to be set to /bin/false (or some derivative) on said machines, so the only thing you'll see after you authenticate is the login banner and your connection will close. I thought to myself, "Fine, no shell for me. I wonder if port forwarding works?" ...

  Kicking ass together: How to improve coding skills as a group

Over the last year and a half, I have worked with a small group of students and staff to create an excellent online learning community at Mendicant University. Unfortunately, because Mendicant is something that we’re intentionally scaling at a very slow pace, we won’t directly reach as many people as we’d like to any time soon. In this post, I’ve collected some of the things that I think contribute to making Mendicant University a great place to learn. I’d love...

JS1K is a website which hosts some competitions to attract geeks from the world to create  JS apps which are less than 1K (1024 bytes).

Starting out as a joke, the first version ended with a serious amount of submissions, prizes and quality.Recently, I revised a previous project of mine and compressed it to 1018 bytes and submitted it. It is an analog clock. The code is shown below:w=c.width;h=c...

  Three ways to define class in JavaScript

In object oriented programming, class is the template of object, it defines the properties and methods of a group of objects. Unfortunately, JavaScript doesn't support class, but we can have some workarounds to simulate class.1. Constructor functionThis is the classical approach, it is also the approach mentioned in many text books. It uses the constructor function to simulate class and it uses the keyword this to represent the object internally.function Cat() {　　this.name = "Kelly...

  Ajax file upload tutorial

Step 1 - AJAX file uploadAJAX file upload tutorialFirst of all I have to say that to create a pure AJAX file upload system is not possible because of security limitations of JavaScript. All of the Ajax upload systems I know use some third party tool/package or only mimics the AJAX feeling. Even so it makes file upload process a bit nicer. In the next section I will present you a solution which imitates the AJAX process, but uses a normal upload process and iFrames.The concept: Create a simp...

  9 reasons to use Zsh

Like majority *nix users, I have been using bash for many years. Sometimes I feel uncomfortable with bash. I tried use some other shells as well such as ksh, tcsh and zsh which I am going to talk about. A few days ago, I found an open source project ranking in the 6th named oh-my-zsh on Github, I downloaded it and had a try with it. It's amazing. We should use zsh to replace bash now. Why do we need to use zsh? Here is a 4 minutes YouTube video which shows many reasons why we should switch from ...
