Problem with File.renameTo in java file io

2012-08-21T16:29:00.002+05:30

renameTo method in java.io.file may not work always [For eg: During File Upload - if destination and source is in different file system, renameTo fails]

As per the documentation of java.io.file -

renameTo

public boolean renameTo(File dest)

Renames the file denoted by this abstract pathname. Many aspects of the behavior of this method are inherently platform-dependent: The rename operation might not be able to move a file from one filesystem to another, it might not be atomic, and it might not succeed if a file with the destination abstract pathname already exists. The return value should always be checked to make sure that the rename operation was successful.



Alternative approach is you can use org.apache.commons.io.FileUtils .


public static void copyFile(File srcFile, File destFile) throws IOException

Copies a file to a new location preserving the file date.This method copies the contents of the specified source file to the specified destination file. The directory holding the destination file is created if it does not exist. If the destination file exists, then this method will overwrite it.

Dimensions for Android

2011-07-11T15:19:00.000+05:30

dp
Density-independent Pixels - an abstract unit that is based on the physical density of the screen. These units are relative to a 160 dpi (dots per inch) screen, so160dp is always one inch regardless of the screen density. The ratio of dp-to-pixel will change with the screen density, but not necessarily in direct proportion. You should use these units when specifying view dimensions in your layout, so the UI properly scales to render at the same actual size on different screens. (The compiler accepts both “dip” and “dp”, though “dp” is more consistent with “sp”.)
sp
Scale-independent Pixels - this is like the dp unit, but it is also scaled by the user’s font size preference. It is recommend you use this unit when specifying font sizes, so they will be adjusted for both the screen density and the user’s preference.
pt
Points - 1/72 of an inch based on the physical size of the screen.
px
Pixels - corresponds to actual pixels on the screen. This unit of measure is not recommended because the actual representation can vary across devices; each devices may have a different number of pixels per inch and may have more or fewer total pixels available on the screen.
mm
Millimeters - based on the physical size of the screen.
in
Inches - based on the physical size of the screen.

To make it absolutely clear – never use any of the above but sp or dp unless you absolutely have to. Using sp / dp will make your Android applications compatible with multiple screen densities and resolutions.

Load any module within a joomla 1.5 content article

2010-04-17T10:14:00.001+05:30

One of the questions that often gets asked is "How can I load a Joomla! 1.5 Module into a content Article? This is in fact an easy thing to do, and can provide useful solutions such as:

Loading in a Paypal Module into an Article.
Displaying Advertising within your Content.
Including Adsense Modules within your Content Articles.
Displaying Audio and Video within Articles.

By default, Joomla! Modules can be placed in any Module Position of the Template, but they do not load into Content Articles.

This tutorial will explain how to enable and use Module loading within your Joomla! Articles, Here are the steps:

Step 1 - Create a new Module or Copy an existing one.

Within your Joomla! Administration, navigate to Extensions > Module Manager.

If you are creating a new Module, click on the New button at the top right of the screen, or you can put a tick in the box next to an existing Module and copy it using the Copy button.

If you copy an existing Module, the new Module will be created or copied and placed within the Module listing.

Step 2 - Edit the Module

If you have created a new Module you will be ready to roll, but if you copied an existing Module click on the title of it to load the Module Edit Screen.

On the left side of the Module Edit Screen you will see some properties such as Module Title, Enabled, Module Position etc. Here is where the power of Joomla! shows itself. Usually we would just click on the Module Position field and select an available Module Position, but it is also possible to enter in your own value here as believe it or not, this field is editable!

We need to edit this field and enter in a custom Module Position Name which will be used for our in-content use. Instead of clicking on the Arrow next to this field, click on the text within the field, and enter in your own value such as, content_custommod

If you need to make other changes to your Module parameters then do so and when you are finished, make sure you click the "SAVE" button at the top right of the screen. Your new custom module position will then be saved with this Module.

Step 3 - Check the Plugin

Within the Administration, navigate to the Extensions > Plugin Manager. Search for a plugin named Content - Load Module, it may already be published but click on the Title of the Plugin to Edit. Once you are in the Plugin Edit Screen, on the right side you will see a list of available Plugin Parameters. Make sure that the option No Wrapping - raw output has been selected, and click Save on the Plugin.

Step 4 - Load Module in Article

Navigate to the Article Manager Screen, and Edit the Article you wish to load the Module within. Click on it's title to load the Article Edit Screen.

Within the desired location of the Article, enter the following syntax in, which is code to tell the Module to load.

loadposition is a constant which activates the plugin. modulename is the custom position that we entered into our module field earlier. In our example we used: content_custommod, so the whole tag would look like: . Your Module has now been told to load into your custom Position, and with the help of the included Joomla! Plugin we have told our Article to show the Module in that position within our page. Refresh the front-end of your Joomla! website to see the module.

IMPORTANT NOTE: Do not enter in a common Template Module Position such as "Top" or "Left" into your loadposition tag. This may display all of the modules that are then set to show in that Position.

Top 10 Dumbest Online Business Ideas That Made It Big Time.

2009-07-08T14:43:00.000+05:30

source :- http://weirdtechnewshub.blogspot.com/2006/07/top-10-dumbest-online-business-ideas.html

1. Million Dollar Homepage

1000000 pixels, charge a dollar per pixel – that’s perhaps the dumbest idea for online business anyone could have possible come up with. Still, Alex Tew, a 21-year-old who came up with the idea, is now a millionaire.

2. SantaMail

Ok, how’s that for a brilliant idea. Get a postal address at North Pole, Alaska, pretend you are Santa Claus and charge parents 10 bucks for every letter you send to their kids? Well, Byron Reese sent over 200000 letters since the start of the business in 2001, which makes him a couple million dollars richer.

3. Doggles

Create goggles for dogs and sell them online? Boy, this IS the dumbest idea for a business. How in the world did they manage to become millionaires and have shops all over the world with that one? Beyond me.

4. LaserMonks

LaserMonks.com is a for-profit subsidiary of the Cistercian Abbey of Our Lady of Spring Bank, an eight-monk monastery in the hills of Monroe County, 90 miles northwest of Madison. Yeah, real monks refilling your cartridges. Hallelujah! Their 2005 sales were $2.5 million! Praise the Lord.

5. AntennaBalls

You can’t sell antenna ball online. There is no way. And surely it wouldn’t make you rich. But this is exactly what Jason Wall did, and now he is now a millionaire.

6. FitDeck

Create a deck of cards featuring exercise routines, and sell it online for $18.95. Sounds like a disaster idea to me. But former Navy SEAL and fitness instructor Phil Black reported last year sales of $4.7 million. Surely beats what military pays.

7. PositivesDating.Com

How would you like to go on a date with an HIV positive person? Paul Graves and Brandon Koechlin thought that someone would, so they created a dating site for HIV positive folks last year. Projected 2006 sales are $110,000, and the two hope to have 50,000 members by their two-year mark.

8. Designer Diaper Bags

Christie Rein was tired of carrying diapers around in a freezer bag. The 34-year-old mother of three found herself constantly stuffing diapers for her infant son into freezer bags to keep them from getting scrunched up in her purse. Rein wanted something that was compact, sleek and stylish, so in November 2004, she sat down with her husband, Marcus, who helped her design a custom diaper bag that's big enough to hold a travel pack of wipes and two to four diapers.With more than $180,000 in sales for 2005, Christie's company, Diapees & Wipees, has bags in 22 different styles, available online and in 120 boutiques across the globe for $14.99.

9. TruGamerz

Faux-suede padded covers for game controllers and gel thumb pads for analog joysticks? No one will buy that. Forget it. The product proved to be so popular, it got picked up by Target.com and Walmart.com and annual sales new exceed half a million dollars.

10. Lucky Wishbone Co.

Fake wishbones. Now, this stupid idea is just destined to flop. Who in the world needs FAKE PLASTIC wishbones? A lot of people, it turns out. Now producing 30,000 wishbones daily (they retail for 3 bucks a pop) Ken Ahroni, the company founder, expects 2006 sales to reach $1 million.
