kExplorer - an open source explorer replacement

romeo84.nospam@nospam.gmail.com (romeosa) — Thu, 16 Jul 2009 11:31:00 -0500

there are a lot of explorer replacement on the net, but none of these has all what I want. So I made my personal portable explorer for files and folders.

The best feature is that you can write extensions for it and see them in a contextual menu or when middle clicking an item.

It's still in beta version, but you can try it: kExplorer 0.5beta.zip (1.63 mb)

I'll publish the source code later (if you need it now contact me).

N.B.: if you want to use extensions, correct paths in custom.xml file.

What you can do with it:

- Main window:

- custom actions for selected file or folder:
-

- view as many simultaneous folder as you want and with the layout you want:

-save and load your layouts:

-click on the little yellow arrow in the address bar to fast browse from that portion of the path. Middle click on Admin to go to C:\Documents and Settings\Admin

-add, remove tabs or extract a tab(view it on a splitted panel)

-write something to the address bar to see previously browsed items ordered by interest

- write something to the search bar to filter the folder content(you can use regular expressions too). Press the search button to start searching into subfolders(you can use regular expressions too)

-

-define custom commands(ex. for middle click on an item) in a simple xml file

- middle click menu when clicking on an empty region:

- tabs are draggable between panels

- there are many little features, but I did not remember them all :-)

Crawling multithread library in java

romeo84.nospam@nospam.gmail.com (romeosa) — Wed, 08 Apr 2009 11:21:00 -0500

This is a simple crawling multithread library I developed(consider this a beta version, but should work fine).
If you need the source-code, let me know.
If you want to send feedback, feel free to post a comment.

This is an example on how to use the library:
1) the library dispatches an event when a new document is loaded, so make a listener for this event; 2) set the maximum number of concurrent threads; 3) start crawling.

MultiThreadCrawler crawler = new MultiThreadCrawler();
crawler.addDocumentCrawledEventListener(new DocumentCrawledListener() {
public void documentCrawled(DocumentCrawledEvent e)
{
System.out.println("" + e.getDocument().getUrl());
//System.out.println("" + ((MultiThreadCrawler)e.getSource()).getRemainingUrlsCount());
}
});
try
{
crawler.setMaxConcurrentThreads(48);
crawler.startCrawling(new URL("FULL_URL_OF_THE_SITE(WITH_HTTP)"));
} catch (MalformedURLException ex)
{
//DO SOMETHING
}

And finally you can download the library here: RomeosaCrawler.jar (23.68 kb)

Use your usb pen to encrypt your data with truecrypt

romeo84.nospam@nospam.gmail.com (romeosa) — Sat, 14 Feb 2009 06:01:00 -0500

Have you ever desired to access your data using your usb pen as the "password"? In this post I'll explain how to do it.

What you need

1) a pen drive
2) truecrypt http://www.truecrypt.org
3) see below

What to do Part 1: create a Truecrypt volume with a keyfile

1) Go to http://www.truecrypt.org and press Download

2) Download thw Vista/XP version

3) Click on TrueCrypt Setup 6.1a

4) Accept(if you want)

5) Select Extrac and click next until finished

6) Run TrueCrypt.exe

7) Select Volume -> Create New Volume

8) Create an encrypted file container and Next

9) Standard truecrypt volume and Next

10) Press Select file and write test.vm, Save, Next

11) Select the size of the volume (ex: 50MB)

12) Click Next

13) Don't put a password, but check Use keyFiles and press Keyfiles..

14) Now Generate Random Keyfile

15) Generate and save

16) Select kf.f as name and click ok, then Close

17) Click on Add file and select that file (kf.f)

18) Press OK, than Next

19) Select FORMAT, then, when finished, Exit

What to do Part 2: protect your volume with an usb pen

1) Copy all files, except the volume, on your pen drive, so that the folder content looks like this

2) Copy this program on the same directory

krypt.exe (364.86 kb)

This is the source if you are interested:

	#Persistent
FileSelectFile, volume, , , Select the crypted volume
Run, truecrypt.exe /q /k "%A_ScriptDir%\kf.f" /v "%volume%" /e, %A_ScriptDir%
Gui, Add, Button, -gexit, Exit volume
Gui, -SysMenu +ToolWindow +AlwaysOnTop
Gui, Show,,krypt
return
exit:
Run, truecrypt.exe /q /d
exitapp
return

3) That's all

How to use your pen drive

Click on the program and select the volume. Now on Desktop -> Computer you'll find the new encrypted drive(ex: E:\). To re-protect the volume and close the session click on CLOSE and remove your pen drive.

If you want to use more than one volume, just create anothe truecrypt volume with the same keyfile kf.f.

Be carefull: don't lost the pen drive or you'll lost all your data!!!
