This post is for documenting two gem installation issues I got when reinstalling an old project. Running bundle update results to two issues on gem: mysql (2.9.1) eventmachine (1.0.3) NoteAgain, this is an old installation of rails gems. Chances are these issues might have been resolved by newer versions, though based on experience, this gem errors are very common. The most usual reason why the

I was digging my old codes when I found this APK I did in 2014. It was a my first trial for a mobile game using Phonegap. Basically, it's a smash that stupid spider game I created out of nowhere in the event of testing whether it would be easy to create a game using Phonegap. Again I said that this is a stupid game I created years ago... You have been warned! A picture of Aragog in Harry Potter

The goal of this tutorial is to capture the image from the web cam and be able to upload it as if you are uploading an image in your Ruby on Rails project. Before starting, it is assumed that you already have a working application that uses carrierwave (and so the set-up for it will not be mentioned here). Also, this may be considered as a continuation of the process stated on this article.

Currently, I have to work on a Windows (specifically, Windows 10) system for two Ruby on Rails projects with different version. Also, the said system is fresh and there wasn't any existing rails installed yet.

There are cases in web designing wherein the image that you are placing are either unreachable or non-existing. This usually happens when image links that are hosted externally are dead or when images' src attribute are set to an invalid location. For this cases, it would be best to replace an image with a default one. Here is a snippet for these matters: (Note that we are using JQuery here,

This is just to document the methods I tried on sending emails with Laravel. All of the mentioned methods work during the development stage. It was my limited access to the hosting server during the production that made me try this different approach. Note that I've done this with Laravel 4. We'll be using three approach here on sending emails: Gmail, Mandrillapp and the default sendmail.

I've just updated my PHP version from 5.4 to 5.5. During the process, Apache and other files were updated too leaving some of my settings broken. One of the first thing I checked after updating is my local database using PHPMyAdmin. Unfortunately typing localhost/phpmyadmin doesn't work anymore. In order to resolve it, I added the code below to apache2.conf and restarted it: #include

Most of the time you'll encounter cases wherein you'll need to extract the entries on your database for duplicates. In that case, here is a query. SELECT * FROM [TABLE_NAME] GROUP BY [COLUMN_TO_CHECK] HAVING (COUNT([COLUMN_TO_CHECK]) > 1) Assumed that you have a table called users and you'll extract items with same the same email address (if for some weird reason that you didn't include

The error occurs upon building a (on my case, it's PhoneGap) project running on Eclipse. This is caused of having two *.jar files inside the bin/dexedLibs directory. These files are generated every time you build your application. Usually, multiple dex files error tells you that you are including the same class file from different sources. SolutionTo resolve this, simply do the following:

Securing your site is one of the most important thing to note when creating and managing your own website. What most people do is to use SSL certificates to apply encryption for their website processes. But the question is, are they really secured? One of the things I've managed for the past few days was to made sure that one of the website we created was really secured even though we used SSL

Coming from a Rails background for an MVC framework, one of the most common things to look for is a validation method for most of your inputs to avoid problems with your data later on. A good example is a uniqueness validation commonly used on usernames and email addresses. In ROR, we can simply add the command for uniqueness in the model by this: validate_uniqueness_of :usernameautomatically,

The way I understand Laravel 4, every time you log out, using the Auth namespace, the function will then update the record of the Users table specifically the updated_at and remember_token attributes. But then, what if the remember_token doesn't exists? Then logging out would return the following error. SQLSTATE[42S22]:Column not found:1054 Unknown column 'remember_token' in 'field list' How I

Azure is a cloud platform provided by Microsoft. With this, you can create a Virtual Machine that can be used as a server for sending and accepting files.

When a developer works on a soon-to-be blockbuster game, there's more to focus on than just the game itself. While not so long ago a simple game announcements was pretty much all the gamers got before the game was launched, things have dramatically changed, with game websites being created months before the game is actually released. Game websites are the perfect marketing tools, allowing the

Mobile apps have exploded on the market over the past two years. Revenues in this sector jumped sky high from $164 million dollars in 2012, to an astounding $1.88 billion in 2013. That's an increase of over a thousand percent, and it's not done yet. The market has taken notice, as shown by the recent IPO of King, creator of the popular Facebook game "Candy Crush Saga".

Responsive web design went mainstream back in 2012, when increasingly more websites finally realized a practical menu and properly implemented social media tools work better than fancy graphics brought to extremes. Responsive web design is a loom that highlights the way development and design should respond to user behavior based on orientation, screen size, and platform. It’s more like a blend

Through that, the programmer receives first-hand information and may have a chance to ask directly the things that are a little unclear. But is it really that helpful?
