Breaksian Travel Blog Career break traveling in Asia

Breaksian pictures on a single location

I have been adding some pictures to different posts on this blog and they are hosted in the domain under the "img" subdirectory. Nevertheless they are just a small subset of the complete photos I have been taking during this career break. When I was planning where to host those images, I decided to use picasaweb (Google Photos) to upload and backup the full set.

I have been using the picasaweb albums for many years and continued using it after the integration into Google Plus. I really like the uploader interface, the available space you get for free and the easiness on sharing the content with the visitors.

My girlfriend was asking me if I had plans to share Australia and New Zealand (my current travel location) pictures and I realize that even if I have been uploading pictures from those very interesting places, they are not "visible" on this blog.

So I added a "photos" link on the top menu pointing to:


This url takes you to a Photos interface where you can see all the albums I have been creating in chronological order. You can always visit my google plus page and see the last pictures I shared, but this view is nice if you just want to see the albums.

I hope you like them.

Currency converter web app update

Last year in one of my earlier posts, I discussed how I had been working on a project to create a small web app to perform currency conversion using an html5 offline web application. I thought I was going to use this tool frequently during my trip in Asia and this turned out to be the case. I'm really happy I have this app with me.

Nevertheless one of the issues I noticed during the daily usage of this web app was the responsiveness loading the new FX data. Sometimes the "loading" screen was hanging there for several seconds, disabling the application in the meantime.

Therefore I changed the logic of the application and now instead of having to wait until the data is loaded, it can use the last FXC data recorded and an unobstructive icon in the question mark button will indicate that new data is being loaded on the background.

You can always click the question mark button to check when was the last time the application data was updated.

Finally if you want to use this application you can point your browser to:


or if you own an android device, you can install the app from here (please note you need to enable temporarily the install from unknown sources in Settings => Security):

Android FXC App apk

I have been testing it during the last 2 days and I believe it works better. Please let me know if you have any suggestion.

How to build a WordPress theme from scratch.

Do you want to build a WordPress theme from scratch using the minimum amount of files, but still keeping a modern look and feel that adapts to mobile and tablet devices? That was one of my first resolutions for this blog during the new year.

I should warn you this post is going to be technical, so if you are not interested in how to create a WordPress theme, you might want to skip it.

I had a general idea how WordPress works and I was using some pretty good themes, but I wanted to create a new one from zero to understand better the system and to have full control on my blog.

After reading some basic documentation online and some trial and error tests. I was able to come up with a theme that I really like! The objective of this post is to describe what I learned, in case you want to do something similar.

First let me outline the conditions I wanted to meet with my new theme:

  • It should be as minimalist as possible. It should have the essential number of files in terms of php pages, JavaScript files and CSS stylesheets.
  • The theme should render correctly in mobile and tablet devices. Full mobile responsiveness wouldn't be an objective, but the look and feel should be pleasant across different screen sizes.
  • It should have a modern look. It should have nice typefaces, borders, and shadows.
  • As part of the minimalist approach the theme should use content delivery networks (CDNs) as much as possible to load external libraries and styles. Only the actual theme files should be stored in its folder.
  • The theme should support the load a dynamic menu on the top and the loading of a dynamic sidebar. This consideration was important in my blog because I'm using both.

The following picture summarizes the layout distribution I wanted to use in my new theme:

This graph will be translated in the following HTML markup:

Final result

You are looking a the final result right now (the theme is running in I created a new breaksianbasic folder in my wp-content/themes directory. My theme contains on a single folder:


1 CSS stylesheet:

  • style.css

1 functions file:

  • functions.php

3 template files for the header, footer and sidebar

  • header.php
  • footer.php
  • sidebar.php

1 template part file

  • content.php

5 template files

  • 404.php
  • archive.php
  • index.php
  • search.php
  • single.php

I will describe next the steps I followed to understand how the template system works in WordPress and what essential files I need to achieve this final result, but if you are impatient and want to get an executive summary then jump to the step 6 "Putting it all together".

Step 1: Understanding the template hierarchy

As I described before I wanted to create the new theme using the minimum amount of files. In order to achieve this objective it was important to understand how the template hierarchy works in WordPress and decide what were the essential files required for my theme.

The WordPress engine produces the different sections of the blog by binding together the content from different template files. If the specific template file is not available for that area or section, then the system tries to go one level up in the template hierarchy until it finds a matching template. This process repeats all the way up to the template file index.php.

Let me illustrate this with a concrete example. In my blog I have different categories for the countries I'm visiting. If a visitor goes to my Japan category (// WordPress will look for a template in the following order:

category-japan.php -> Japan as the category slug. category-22.php -> 22 as id of the category Japan. category.php -> Categories general template. archive.php -> Archive pages general template. index.php -> As last resort, blog general template

I decided I could live with the same template for the archive and the categories pages, so I just included a archive.php file in my theme. I repeated the same thinking process across my different blog section and I decided to create only the following five template files:

404.php -> Custom 404 not found page with search functionality.
archive.php -> Archive pages, categories, tags and authors.
index.php -> Home page and the static pages.
search.php -> Search results page template.
single.php -> Single posts template

I also included some additional files for the header and the footer that I will explain below. If you want to better understand the template hierarchy structure, the following graph from the official Worpress codex documentation, summarizes it quite well:

Step 2: Understanding the get_header, get_footer and get_sidebar functions.

In most of the websites the header, the footer and the sidebar are relatively static. Those elements give consistency to the look and feel across the different pages and that was the case in the theme I was creating.

I could add the whole HTML markup to open and close the html document in each one of the files described in the previous section, but it would make more sense to automate the header, footer and sidebar generation.

Fortunately WordPress includes functions to automatically load those sections whenever you deem necessary:

 get_header() => Loads the contents of header.php
 get_footer() => Loads the contents of footer.php
 get_sidebar() => Loads the contents of sidebar.php

It is as simple as that. You might want also to include wp_head() in your header.php file to hook up the styles and javascript files and wp_footer() in your footer.php file to attach some additional javascript files. A simplified version of my header, footer and sidebar is next:


<!doctype html>
<html <?php language_attributes(); ?>
<meta charset="<?php bloginfo( 'charset' ); ?>">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title><?php wp_title( '|', true, 'right' ); ?></title>
<?php wp_head(); ?>
    <body <?php body_class(); ?>>
    <div class="topmenu">
        <?php wp_nav_menu( array( 'theme_location' => 'header-menu' ) ); ?>
    <div class="maincontainer">
        <header class="blog-header">
            <h1><a href="<?php echo home_url(); ?>" class="blogname"><?php bloginfo('name'); ?></a> 
            <span class="blogdescription"><?php bloginfo('description'); ?></span></h1>


<div class="footerwrapper">
<footer class="blog-footer">
<p><?php bloginfo('name'); ?> - &copy; <?php echo date('Y');?>
</div><!-- closing of the main container -->
<?php wp_footer(); ?>


<div class="sidebar">

&lt;?php if ( function_exists('dynamic_sidebar') &amp;&amp; dynamic_sidebar() ) : else :
endif; ?&gt;


Step 3: Understanding the loop concept.

If you read any documentation about WordPress sooner or later you will stumble upon the loop concept. The idea is that the system pulls all the posts for a specified page (ie home, category, archive) and it formats all these matching posts according to the criteria described in the loop tags.

You can add to the template the following opening and closing tags of the posts loop:


Using the predefined template tags you can extract the link to the post (the_permalink()), the title of the post (the_title()), the date and time when it was published (the_time()), the categories if it belongs to any (the_category()) and the actual content of the post (the_content()).

Based on the previous loop concept and the supported tags it would be very easy to create a template file that goes over the posts list and prints out the main fields, including the content.

if (have_posts()) :
  while (have_posts()) : the_post(); ?>
  <article class="post">
    <h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
      <div class="entrymetadata">
        <span class="date"><?php the_time('F j, Y'); ?></span> | 
       <?php the_content(); ?>
  <?php endwhile;
else :
  echo '<p>No content found</p>';

Step 4: Understanding the get_template_part function.

As described in the Step 2, WordPress allows loading the header and the footer automatically by using the get_header() and the get_footer() functions, but the system offers additional functionality to reuse sections of templates shared across different pages using the get_template_part function.

Getting a template part makes easy to reuse the most common parts of displaying a blog post: Printing the title, the publishing date, the categories and its actual content. For my theme I decided to create a template part file called "content.php" and to put there the reusable "post" markup and WordPress tags.

I included in my content.php file, part of the code I described in the previous step



and then I include this content with the get_template_part function:

  while (have_posts()) : the_post();
    get_template_part( 'content', get_post_format() );

else : echo '

No content found

'; endif;

Step 5: Understanding the functions.php file and registering styles

According to the official WordPress documentation the functions.php file behaves like a WordPress Plugin, adding features and functionality to a WordPress site.. This file can be really useful because you can use it to register the scripts and styles used by your theme.

In the case of the breaksianbasic theme, I'm using it to:

  • Register the main CSS stylesheet (style.css), so it gets loaded in the standard WordPress header.
  • Include the external library "font awesome". This library has some nice type-fonts and some beautiful icons.
  • Register the header menu and the sidebar to manage both dynamically from the theme customize editor.

My functions file looks like this:

function breaksianbasic_resources() {

wp_enqueue_style('style’, get_stylesheet_uri());

// Add Awesome Font wp_register_style( 'awesome-fonts’, ‘//’); wp_enqueue_style( ‘awesome-fonts’ );

} add_action('wp_enqueue_scripts’, ‘breaksianbasic_resources’);

function breaksianbasic_registermenu() { register_nav_menu('header-menu’,__( ‘Header Menu’ )); } add_action( 'init’, ‘breaksianbasic_registermenu’ );

function breaksianbasic_widgets_init() { register_sidebar( array( ‘name’ => __( 'Widget Area’, ‘breaksianbasic’ ), ‘id’ => 'sidebar-1’, ‘description’ => __( 'Add widgets here to appear in your sidebar.’, ‘breaksianbasic’ ), ‘before_widget’ => '

', ‘before_title’ => '

', ‘after_title’ => '

', ) ); } add_action( 'widgets_init’, ‘breaksianbasic_widgets_init’ );

The next step is to describe how all the previous steps fit together.

Step 6: Putting it all together.

In the previous steps I described the different functionalities WordPress offers to create a new theme. I learned about those and as I was reading and discovering new tips, I started to incorporate them in my own templates and structuring more the theme. Based on those steps I described before, I wanted to recap now how I put it all together:

  • Mock the HTML template: I mocked an single HTML template with the look and feel I wanted to get for my blog. I added all the CSS rules to styles.css
  • Setup functions.php: Created a functions.php file and registered the previous styles.css file, plus dynamic top header menu and sidebar (as described in the step 5).
  • Header, footer and sidebar: I created the files I was going to use for header, the footer and the sidebar (as described in step 2): header.php, footer.php and sidebar.php. I extracted the header and footer from my HTML mock and I filled those files with code snippets similar to the ones mentioned in Step 2.
  • Main content template part: I created a content.php file and I put inside the template part content I was going to use in most of the pages:



  • Created the index.php template: I created the main index template including the header, the sidebar and the footer. I added the loop described on step 3 on the left side div and the sidebar on the right div. I reused the content.php created in the previous step:


    <?php get_header(); ?> <div class="leftdiv"> <?php if (have_posts()) :

    while (have_posts()) : the_post();
       get_template_part( &#39;content&#39;, get_post_format() );
    else :
        echo &#39;&lt;p&gt;No content found&lt;/p&gt;&#39;;

    ?> </div> <div class="rightdiv"> <?php get_sidebar() ?> </div> <?php get_footer(); ?>

  • Created the archive.php template: I reused the main index template for the archive.php file, but added an additional field required for archive date or categories
  • ....
    if (have_posts()) :
            <header class="page-header">
                    the_archive_title( '<h1 class="page-title">', '</h1>' );
                    the_archive_description( '<div class="taxonomy-description">', '</div>' );
  • Created the single.php template: I lso reused the main index template for the single.php template file, but in this case I added an additional field for including the comments.
  • ...
        else :
            echo '

    No content found

    '; endif; ?>
    <div class="comments">
        <?php comments_template(); ?> 

  • Created the search.php template: I reused the archive template file, but I changed the archive date or categories field for a "search query" field
  • ....
    if (have_posts()) :
            <header class="page-header">
                <h1 class="page-title"><?php printf( __( 'Search Results for: %s', 'breaksianbasic' ), get_search_query() ); ?></h1>
  • Finally I uploaded all the files to the template directory, I selected the new theme, I customized it and I start using it in

Step 7: Final touches and conclusion

I described in this post the general process I used to create a new WordPress theme from scratch. As always, I used tons of official a non-official documentation available online. I have been adding many small touches to my theme since I finished the first iteration.

For example, since I'm using the awesome font library, I created some Social buttons, reusing some of the icons provided in it.

  &lt;div class=&quot;brk-social-buttons&quot;&gt;
      &lt;a href=&quot;//;?php the_permalink(); ?&gt;&quot;&gt;&lt;i class=&quot;fa fa-google-plus brk-social brk-social-plus&quot;&gt;&lt;/i&gt;&lt;/a&gt;
      &lt;a href=&quot;//;?php the_permalink(); ?&gt;&quot;&gt;&lt;i class=&quot;fa fa-facebook brk-social brk-social-facebook&quot;&gt;&lt;/i&gt;&lt;/a&gt;
      &lt;a href=&quot;//;?php the_permalink(); ?&gt;&quot;&gt;&lt;i class=&quot;fa fa-twitter brk-social brk-social-twitter&quot;&gt;&lt;/i&gt;&lt;/a&gt;    
      &lt;a href=&quot;//;?php the_permalink(); ?&gt;&quot;&gt;&lt;i class=&quot;fa fa-reddit brk-social brk-social-reddit&quot;&gt;&lt;/i&gt;&lt;/a&gt;   

I hope my experience was useful to you. For me it was definitively very interesting to create a new wordpress theme from scratch!.

Outbreaks healthmap

When I was preparing my trip to Asia and I was getting all the vaccinations required I stumbled upon a very interesting website developed by a team at Boston Children's Hospital called HealthMap. This site created by a team of researchers, epidemiologists and software developers provide realtime information about disease outbreaks from a broad array of infectious diseases.

The map is quite interactive allowing you to move around and zoom in / zoom out to get additional information about specific cities and regions. I was checking this site recently because of all the Ebola craziness in the media and I realized they offer now a section dedicated to this disease: // If you are traveling I think this is a great site to have in your bookmarks.


Update on laundry kit

Before I started my career break in Asia, I wrote a post here describing that I had completed my laundry kit that included: a A Scrubba wash bag (a nice gift from my sister in law and my brother) and a elastic line to hang the clothes either with a hook or a sucker.

This morning the weather was horrible in Busan so I took the opportunity to look for a coin operated machine to wash my clothes. I found it and the prices are not too bad: 3500 KRW for washing and 3500 for drying in medium size machines.

While I was waiting for the clothes to be ready I started to chat with my brother (yeah the place has free wifi too). He asked me if I had used the wash bag and I told him that it had worked pretty well while I was visiting warmer latitudes (Malaysia, Singapore and Vietnam), but here in Korea, I haven't used it as often because the weather doesn't allow the clothes to dry quickly.

As you can see from the picture above both the bag and the elastic lines were a success! This was taken in Malaysia one week after I was on the road. Now I should clarify that the line hanger works well with the hooks, but the suckers on the other hand … kind of suck! :)

Flashpacker budget tracking using the phone


When I was planning my trip to Asia I thought about different ways for tracking my budget, particularly because I was going to be on the road for a while and I was going to spend money in different currencies.

I remembered I bought a couple of years ago an personal finance application for Android called AnMoney. I decided to undust it and test if this was a good alternative to perform this type of tracking. Then I discovered that the last version handles very well having accounts in different currencies, so that was exactly what I needed.

As you can see from the screenshot above I have been defining cash accounts for the currencies of the countries I have visited so far and then when I do currency exchanges or withdraw money from ATM machines, I "transfer" the money to those AnMoney accounts so I can keep an eye on what I'm spending.

Of course I'm not tracking every single cent that I'm spending, that wouldn't be fun! (I have to roundup many items), but when I pay for a hotel, book a flight or get a train ticket, I try to write it down using the application. It works like a charm for me.

In case you want to give a try (they offer a limited free version as well) this is they "search query in the Google Play Store [anmoney]
