Also sick of Globe@Home?


Globe is the monopolist company for the Philippines. They provide WiFi (pre-payed) as well as contract services (up to 100 Mbps, which is nothing, compared where I come from (Netherlands)

Would it be such a big technical problem to send us a notification when our load is not enough for the week to come instead of cutting us off without any notification? I don’t think so!

The Linux Operating System (used by all Internet Providers worldwide) comes with all necessary tools to implement this feature! It’s free and Open Source. So why not use it?

I don’t know!

The only thing I do know is that it requires 4 lines of simple scripting code to implement this feature:

  1. A Database lookup.
  2. A simple check if your load is enough for the coming days.
  3. If not, the mail command.
  4. A cron scheduled command which calls the scripts above.


Globe is lazy, selfish and abusing their monopoly position in the Philippines!

What can we do?
  • Ask your 12-year-old child to write the script for you.
  • Ask me, I’ll do it for a beer! I’m running this service from my cloud server in Singapore, so why not for others? Just send me a message. It’s free too!

Above everything the Java Programming language was designed to

be a Networking Language by Sun Microsystems early nineties Sun’s slogan was “The Network is the Computer”.

Actually John Gage wasn’t completely right. Although it has become true for some systems   Computers are still the Computer, weather they are smartphones, smart watches, PC’s, Macs, iPads, Android tablets or Virtual Machines are still the real computers. Although they have become more and more connected and serve the API’s which  are accessed trough the networks.

Public API’s are becoming more and more available and are used as services which indeed make the Network. The coming of SOA slowly is making things better.

Time to see how you can connect to a (web) service using the API.

Opening and reading from a url

In the Opbject which represents an url is the URL object. You can instantiate it as follows:

URL url = new URL("");

The next step is to open a connection:

HTTPUrlConnection con = url.openConnection();

Now we are ready to read from the connection. This is similar to reading from a file:


BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String inputLine;
        while ((inputLine = in.readLine())
          != null) 

This prints the html of my homepage to the console. If you want to write it to disk, follow the instructions on writing to a file.

As you can see, the methods for are consistent everywhere, which makes the Java programming language easy to learn.

i/o streams should always be closed!!!


This article demonstrates how to make a http connection and read a full HTML page from an HTTP connection using only plain Java objects. In another article we will post something to the http server.
