How to simulate "No to all" when copying in Windows XP

If you've ever copied a folder's worth of files in Windows, you've come across the Confirm File Replace dialog, which asks you if you want to replace an existing file with a new file. You have the option to answer Yes just for this file, Yes to All—which will just replace all the originals with the new copies—or you can say No; what's missing is a button to say No to All. Rather than clicking No countless times if No to All is what you really want, tech weblog Online Tech Tips points out that Windows simulates the No to All response if you hold the Shift key and then click No.

eM Client - Another Outlook Killer ?

Looking for another alternative to Microsoft Outlook? While Mozilla Thunderbird offers many of the same features as Microsoft's email client, you need to install plugins to add calendar and task management features. eM Client, on the other hand, comes equipped with a full featured email client and contact, task, and calendar managers.

While it's not exactly an Outlook killer yet, eM Client's developers are working on a few killer features:

Google Calendar and Contacts Sync
ActiveSync support
Universal translation tool
Facebook integration
IM integration
Anti-virus integration

eM Client also has a highly customizable interface, which is always nice.

How to reverse a doubly linked list ?

I talked about how to reverse a singly linked list earlier. That was slightly tricky to understand.
Reversing a doubly linked list is relatively easy. The logic is : You need to keep on changing the next and previous pointers as you traverse the entire list. Here is the code snippet in Java :

public void reverse()
{
    if (first == null) 
          return;

    DoubleNode previous = first;
    DoubleNode current = first.next;
    first.next = null;
    while (current != null)
    {
            DoubleNode next = current.next;
            current.next = previous;
            previous = current;
            current = next;
    }
    first = previous;
}

Google Calendar going offline ?

It looks like Google is preparing to add offline functionality to Google Calendar. A few days ago the folks at the Digital Streets blog noticed that Google seemed to have added some code to the Google Calendar page that would bring up a prompt to install Google Gears for access to 3 months worth of calendar data while you're offline. But once you install Google Gears, nothing happens.

Googlified noticed a new option in the settings section of Google Calendar. Go ahead and check, odds are you'll see an "Offline" tab in your own calendar settings. When you click the tab, you're told to download Google Gears. Unfortunately, once you install Google Gears, nothing seems to happen. Visiting Google Calendar with Gears installed just brings up the plain old Google Calendar with no option to save your data for offline viewing. But we get the feeling that Google wouldn't be adding features to the Google Calendar settings menu if the company didn't plan to activate those features soon.
