TinEye is the “reverse image search engine” you need – you just have to upload your image (or give the URL-address, if it is published on a webpage), and you will get results from other pages, containing the same image. It gives you the chance to learn what it is, since you will probbably get pages, containing info about it. Here is how it works:

It is also a good tool to see who is using your images

Open up Google and write: define:<term> in the search field, where <term> is the word you want defined. You will then get one or more definitions of the term from different sources like Wikipedia, Princeton WordNet, etc. You can also find definitions in languages, other than English, if available.

Example: define:blog

Scenario: you have to enter a lot of similar rows of data, for instance the cells in column B, column C and column D. Column A is the position number (1., 2., … ) and columns E, F, etc. perform some calculations from the data you have entered.

Now, there is a fast way to enter data (especially using the numeric keypad) without even touching the mouse, or needing to use the arrow keys to navigate:

1. enter the number in the first cell in the row (column B)
2. press TAB
3. enter the number in the second cell in the row (column C)
4. press TAB
5. enter the number in the third cell in the row (column D)
6. press Enter

MS Excel automatically makes active the cell below the one, that you started from (Column B / next row). In this way you can only use the keyboard and not waste time with moving around the worksheet (arrow keys and/or mouse).

There is a workaround for that, involving a simple preliminary network setup + creation of a shortcut. I will briefly describe it here in 3 steps (you will have to repeat for each connection profile you would like to create). Here is how it goes:

[preparation]
Open a command prompt (click START – Run… then type cmd and click OK),
type md %windir%\netsettings (or copy it from here and paste it in the command prompt with a right-click) and hit Enter. Don’t close the command prompt yet.

1. Make all network settings for the current profile (e.g. Office) – go to Network Connections, select the appropriate connection (wired and/or wireless) and set IP-address, network mask, default gateway, DNS servers, etc.
2. Execute in the command prompt the following command
   netsh -c interface dump > %windir%\netsettings\office.txt
   and hit Enter.
3. Create a shortcut on your desktop by minimizing all open windows, right-clicking on an empty place on the desktop and selecting New -> Shortcut…
   In the new window that opens, type (or better paste) the following
   netsh -f %windir%\netsettings\office.txt
   and click Next…
   Type a name for the profile (for instance Office settings) and click Finish.

Repeat steps 1-3 for as many profiles you need to create, changing office.txt with home.txt (etc.) in steps 2 and 3. Give each profile shortcut a distinguishable name.

You can now switch between different network profiles by simply clicking the appropriate icon on the desktop!

Note that this approach creates a full network profile (including settings for all network interfaces – wired and wireless), so in rare situations you might need to create different combinations of settings. It is also useful to have a setting with all connections set to auto, in case you need to access networks in hotels, airports and other public places.

There are several ways to access news via RSS. One is to read an aggregator website, into which somebody has pre-selected sources based on a common criteria – all technology news or all blogs from a certain country. The other is to select the sources yourself and display the new items in some sort of an application – either web-based or a program, installed locally on your computer. Most common web-based applications include Google Reader, Bloglines, Netvibes, Technorati and My Yahoo! to name just a few. The local application approach relies on an installed program, most commonly the very browser you are reading this site with – Mozilla Firefox‘s Live Bookmarks or Internet Explorer’s Feeds, a mail client (Outlook, Thunderbird or Apple Mac OS X Mail) or a standalone RSS-reader.

After having tried a lot of different approaches and solutions, my personal favorite is now the Thunderbird application. And you can start by subscribing to the Digital Day’s RSS Feed.
