Read HFS+ from Linux
The OS X filesystem, HFS+, by default is in read-only mode in my ubuntu.

So I installed hfsprogs using
```
sudo apt-get install hfsprogs
```
(you have to enable universe package-source)

to mount the "Macintosh HD", use this
```
$cd 
$mkdir osx
$sudo mount -t hfsplus -o force,rw /dev/sda2 osx 
```
Nevertheless, it still mounted as read-only, and some folders refused to open at all.

Here the trick. We have to have same uid as the os x.

so, create new user
```
sudo useradd -d /home/newuser -m -s /bin/bash -G root newuser

sudo passwd newuser

sudo usermod --uid 501 newuser

sudo chown -R 501:newuser /home/newuser
```
.

by default the first user on OSX has an uid 501.

Now, as we have the same uid on linux and OS X. We could freely read the filesystem.

#MelawanAsap

Sepertinya tahun depan tidak akan ada kebakaran hutan,

tak ada asap,

karena tak ada lagi yang bisa dibakar.

List Folders and Files Recursively using Google App Script.

I got the problem because using 'recursive' as function name, :)

At least now I know that, :)

The next? Beautifying the result, :D

function listFilesNFolders(form) {
  var list = [];
  var lv = 0;                    //lv for level or depth
  list.push(['tadaa...<br>']);
  list.push(['heheh...']);
  var row = [];
  row.push('<br> Hello World!!! ');
  list.push(row);
  
  var home = DriveApp.getFolderById('0BxZS62a5NdNYUGxySmp2QW41OUU'); 
  list.push('<br>');
  list.push(home.getName());
  crawl(home,list,lv);
  return list;
}

//don't use 'recursive' as function name, it won't work
function crawl(home,list,lv){
  lv++;
  list.push('<br>tadaa...'+lv+'...');

  var files=home.getFiles();  
  while (files.hasNext()){
    var file=files.next();
    list.push('<br>f '+file.getName());
  }
  
  var folders=home.getFolders();
  while (folders.hasNext()){
    var folder=folders.next();
    list.push('<br>d '+folder.getName());
    
    crawl(folder,list,lv);
  }
}

function doGet(e) {
  return HtmlService.createHtmlOutputFromFile('form.html');
}

Jika MotoGP Sepang gagal karena asap, maka Rossi cukup finish ketiga di Valencia untuk jadi juara dunia, :)

Trik Old Shatterhand di Llano Estacado untuk mendatangkan hujan sepertinya tak berhasil di sini.

Global Variable on Google App Script

I have trouble accessed it within function,

so I pass it to every function,
not so elegant solution, but it works, :) .

In the code below, I have global variable named list.

I have to passed as parameter on function dummy in order to edit its value or it wouldn't affected or have error message or undefined (I experienced both, :) )

function listFilesNFolders(form) {
  var list = [];
  list.push(['tadaa...<br>']);
  list.push(['heheh...']);
  var row = [];
  row.push('<br> Hello World!!! ');
  list.push(row);
  
  var home = DriveApp.getFolderById('0BxZS62a5NdNYUGxySmp2QW41OUU'); 
  
  dummy('<br> test',list);
  return list;
}

function dummy(d,list){
  list.push(d);
}

The form

 <form id="myForm">
     <input type="submit" 
    value="OK"        
    onclick="
    this.value='Proses';
    google.script.run.withSuccessHandler(fileUploaded).listFilesNFolders(this.parentNode);
    return false;
 "
                    >
 </form>

#MelawanAsap

Ini terjadi di Malang, bukan hutan, ini ladang tebu sehabis panen.

Naik sepeda lewat beginian, hanya 20 meter terpapar asap, rasanya...

Cuma sekian detik.

Tak terbayangkan jika terpapar berbulan-bulan, di setiap tempat, di setiap waktu

List Files and Folder in Certain Folder in Google Drive using Google App Script

Here it is.

I used getFolderById() to determine the folder I want to list the files and folders inside. I used home as variable name of the folder

home.getFiles() is used to gets a collection of all files in home.

home.getFolders() is used to gets a collection of all folders in home.

I have list and row as array or tuple or 'list' to accommodate the result. Maybe it's wasting time to have two variable, but I plan to write code to list 'files and folders inside subfolders' recursively. I know maybe it didn't even need that array variable, :). But just in case...

function listFilesNFolders(form) {
  var list = [];
  list.push(['tadaa...<br>']);
  list.push(['heheh...']);
  var row = [];
  row.push('<br> Hello World!!! ');
  list.push(row);
  

  var home = DriveApp.getFolderById('0BxZS62a5NdNYUGxySmp2QW41OUU'); 
  // Log the name of every file in the user's Drive.
  var files = home.getFiles();
  list.push('<br>Files:');
  while (files.hasNext()) {
    var file = files.next();
    list.push('<br>-',file.getName());
    //Logger.log(file.getName());
  }
  // Log the name of every folder in the user's Drive.
  var folders = home.getFolders();
  list.push('<br>Folders:');
  while (folders.hasNext()) {
    var folder = folders.next();
    list.push('<br>-',folder.getName());
    //Logger.log(folder.getName());
  }
  
  
  return list;
}

function doGet(e) {
  return HtmlService.createHtmlOutputFromFile('form.html');
}

The Form

  <form id="myForm">
    <input type="submit" 
    value="OK"        
    onclick="
    this.value='Proses';
    google.script.run.withSuccessHandler(fileUploaded).listFilesNFolders(this.parentNode);
    return false;
    "
                    >
  
</form>

<div id="output"></div>

<script>
    function fileUploaded(status) {
        document.getElementById('myForm').style.display = 'none';
        document.getElementById('output').innerHTML = status;
    }
</script>

<style>
 input { display:block; margin: 20px; }
</style>

The Result
