I need to learn Ruby on Rails for my new job. I’m a little thrilled about this chance to learn a new language, and I’m trying to get started with it on my Macbook which runs OS X El Capitan 10.11.5. I already have Ruby here, I don’t remember if pre-installed though. It’s out of […]

Add “options menu” to an AppCompatActivity (Android App Development)
Adding an “options menu” to an Android app’s Activity is quite simple. This is an example of what an Android options menu looks like. Look at the icon that looks like 3 dots vertically stacked. My dev environment status as of writing this Android Studio version: v. 2.1 OS: Mac OS X El Capitan v. […]
Prevent direct access to directories of subdomains
From my hosting platform (e.g. cPanel), I created two subdomains for web apps. The web apps reside in the following directories: /foo/bar/app_one/ /foo/bar/app_two/ And the subdomains I created are accessed through these URLs: http://app_one.bar.domain.com (pointing to /foo/bar/app_one/ directory) http://app_two.bar.domain.com (pointing to /foo/bar/app_two/ directory) For security purpose, I don’t want anyone to access the web app […]
Laravel 5: activate API token guard and print “Unauthorized” instead of login redirect
In Laravel 5, I wrap my API routes in a route group like this:
|
1 2 3 |
Route::group(['middleware' => ['auth:api','throttle']], function() { // API routes here }); |
Notice that I use auth:api and throttle on my middleware array. auth:api turns on the auth middleware with API token as guard, while throttle activates rate limiter for APIs. To get started with API token authentication, you may read https://gistlog.co/JacobBennett/090369fbab0b31130b51. […]
Android app dev: ShareActionProvider in Activity & Fragment
I’ve been taking the Developing Android Apps course on Udacity, and yesterday I encountered a difficulty in solving the Quiz: Share Intent. One of the course’s goal is to build the Sunshine App – an Android app with weather forecast. In that quiz I had to implement ShareActionProvider on my DetailsFragment so that a share […]
Laravel 5 RESTful API with Basic Auth: PHPUnit Testing
I’ve been using PHPUnit to test my RESTful API. PHPUnit is ready to use in Laravel. In my Laravel-based RESTful API, I have an endpoint /api/users which returns JSON data when you send a GET request. The API will only return such data if the client sends the corrent username and password (Basic Authentication). The […]

Android Maps: Get current location coordinates with Google API Client Builder
To get your current location via Google Map in an Android app, this was how we do it:
|
1 2 3 4 |
@Override public void onMapReady(GoogleMap googleMap) { Location location = googleMap.getMyLocation(); } |
Stop. Don’t use that! The method GoogleMap.getMyLocation() is deprecated. Instead, we need to use FusedLocationApi and the callback onLocationChanged(). Here’s an example code that works for me ( consider copying the contents of onResume() into onStart() […]
Bash: rename all files in directory, replacing all hyphens (-) with underscores (_)
I don’t want to waste time doing things manually when I can run a script that will help me save time and effort. When using Linux or Mac command line (bash?), if you want to rename all files in your present directory and replace all hyphens – with underscores _, run this command:
|
1 |
for f in *-*; do mv "$f" "${f//-/_}"; done |
