Bower is a package manager for the web and offers a generic solution to the problem of front-end package management. For example the Polymer library uses Bower for package management. In fact, the primary reason for me to install Bower was to use Polymer. The main difference between Bower and pther package managers is that Bower will manage any packages, even if that means HTML, CSS, or images. In this case, a package means any third-party code, usually publicly accessible from a Git repository.
A couple of years back if you needed to run PHP on Google App Engine you were required to use a open source tool like Quercus, a 100% Java implementation of PHP, to run your PHP applications on the App Engine. However, as you would have guessed, it was not easy to work as with using a native PHP implementation. Now that App Engine natively supports PHP and MySQL, you can easily write PHP applications.
Descriptive statistics can be quite useful for simple analysis of records in a database. For example, to calculate average numbers of sales or products for a particular duration, or the Variance of sales for a month etc.
We can easily calculate standard descriptive statistic measures in MySQL such as MEAN, SUM, STANDARD DEVIATION, VARIANCE, MIN and MAX using built-in functions. Below is a sample student table with student id and scores which we will use for calculating descriptive statistical measures.
Developers have a lot to consider when it comes to the user experience: making sure everything works, how intuitive it is to use, and that it beats the competition. But one thing that developers have to consider now on top of everything else is how to deliver all of these same variables in a pocket-sized, mobile format.
Having a mobile app is something that users expect from brands now, and it’s a big part because the rising level of reliance on mobile devices. Mobile functionality is something that’s impossible to ignore, and in order to develop properly for it, you need to understand who’s going to be using it.
With multiple versions of a site now common, it is important to redirect to the appropriate version depending on the type of device the user is using. For example if a user is viewing a website on a mobile device, we should be able to redirect to a mobile friendly version of our site. For this purpose we should be able to detect the device the user is using and act accordingly. This is where mobile detection libraries come in handy.
Date manipulation is a common programming task a developer does regularly and many times can get tricky and cumbersome. If youy web applications relies heavily on date manipulation on the frontend than moment.js is the library you have been looking for.
In short this is what you can do with moment.js
moment("20111031", "YYYYMMDD").fromNow(); // 2 years ago moment().endOf('day').fromNow(); // in 2 hours moment().startOf('hour').fromNow(); // 9 minutes ago moment().subtract('days', 6).calendar(); // Last Wednesday at 10:09 PM moment().add('days', 1).calendar(); // Tomorrow at 10:10 PM
The Web Speech Synthesis API allows your web apps to convert page text or any other predefined or dynamic text to be rendered to speech. Although currently supported only in Chrome 33, the api enables you to add nice accessibility support to your web apps. However, I’m hard-pressed to find a suitable application for the use of it, besides maybe online games and browser slideshows with background commentary. A demo is given below.
With an increasing number of users migrating to WordPress, moving data from an existing CMS to WordPress has become an essential process in the transition. Although migrating small databases from another CMS can be done in a few hours, large databases can take days or even weeks.
In one of my recent endeavors of the same, I had to migrate a relatively small user database from an old CMS to WordPress. Although a small task, some points tripped me and took a little longer than planned. Below are some of the points and recommended tools to consider when migrating existing databases to WordPress.
My standard debugging tool when using PHP is xdebug. Pairing xdebug with Komodo gives me a very productive environment for building PHP applications. However, testing an application code on a hosted server can be many times frustrating as one has only the
var_dump functions at our disposal. What I need is a library that I can easily install on the server and start using.
Being primarily a developer, designing a web page is not my forte. I usually design web pages using notepad++ and a browser. Although I use grid support, many times I just wish for a simple overlay guide which I can use to layout the different web components. Recently I found one with RulersGuides.js.
