The address book software will automatically recognize possible duplicate contact information and display a dialog to the user that proposes a few ways how to deal with the data including options to skip or edit.

Important features offered by Open Contacts include:

• Unlimited data fields to store any contact info. Along with predefined fields, you may add unlimited data fields grouped by section.
• Manage relationships between individuals, organizations and departments.
• Comprehensive Categories. You may click on a category to view contacts of the category, or right click to list contacts of subcategories recursively.
• Search through any data field, and search birthday of people.
• Interact with Windows applications of telephony, Skype, emailing or Web/File browsing etc.
• Map service with Google Maps. You may use either single line address or multi-line address. Yahoo Maps and Microsoft Live Maps are also supported through custom action plug-in programs.
• Print contact info and labels on papers of different sizes.
• Import from MS Outlook, Outlook Express (WAB), Eudora, Netscape/Mozilla Thunderbird, XML (xCard), CSV, LDIF, Vista and vCard.
• Export to indented text, CSV, Excel, vCard, XML (xCard), HTML, hCard and XFN (XHTML Friends Network).
• Portable. You may bring your address book database and the program in an external device such as a USB flash disk, and run the program on any Windows PC.
• LAN supports for multiple users in Local Area Network, using true Client/Server architecture.

Quite a few can be very interesting for users in specific work situations. The only real downside to this excellent address book software program is the rather outdated user interface that feels slow in certain situations. Open Contacts is available as a free download from the developer’s homepage.

Opera Unite is modularized and comes with so called services that can be installed to extend the functionality. This may remind many users of Firefox add-ons but it is actually a completely different technology that requires more than just clicking on an install link. Currently seven services are offered, they are:

• Media Player – Accessing the music collection from anywhere on the Internet.
• File Sharing – A way of sharing files directly between users.
• Fridge – A note leaving application that other people can use to leave notes on a computer system.
• Web Server – Hosting a web server from the local computer system.
• Photo Sharing – Share photos without uploading them first.
• The Lounge – A chat interface hosted on a computer system.

The Opera team has created a user guide to get users started with Opera Unite. Opera Unite is available as a separate preview release which can be downloaded for all supported operating systems from the Opera Labs website. The download will actually replace the current version of Opera 10 if the user decides to install it in the same installation directory.

Opera Unite is then available in the left panel after installation. Starting the actual home server requires an Opera account. A homeaddress is assigned to every user signing up for Opera Unite in the from “http://computername.username.operaunite.com/” with the user selecting the computer name. The username will be the Opera username.

Once that has been setup the service that has been selected by the user gets setup. Setup of the file sharing module for example requires the selection of a directory on the local computer that will be used for that purpose. Each service that has been activated can then be accessed from the created homepage if the user accessing it has sufficient rights to do so.

The file sharing page on the server is for example protected by a password by default which can be changed in the root home directory. It offers three different access rights which make it possible to allow public access (everyone can access them), private access (only the root user can access the files) or password protected access.

Verdict:

Opera Unite offers something that web browsers do not offer out of the box. The usefulness of the service on the other hand depends largely on the user’s system configuration. If the user runs an home server then it might not be needed to run Opera Unite as well. Users who prefer to access everything from one program might find Opera Unite helpful especially if the developers and users begin to add new modules to the service. Not really a reinvention of the Internet but a nice service nevertheless.

The blog lists the major changes of the core update mentioning in the end that about 1.1 million data values have been affected by the search engine update. Most of the changes listed in the blog post add new searches or information to the search engine. This includes for example the updates to some European countries like Slovakia, regions (like Wales), country borders (India, China..) but also more interesting comparisons (USA deficit vs. UK), combined time series plots of different quantities (population Germany gdp) and additional ways of searching for information and data entries.

There is obviously still a fundamental different between the information that are provided by Wolfram Alpha and classic search engines like Google Search, Bing or Yahoo Search. The developers are however on a good way to fill a gap that most users were probably not aware of until they discovered that they could use Wolfram Alpha in a certain way to compute information that would take lots of manual work otherwise.

Still, the search engine is limited and it sometimes depends on the phrase if it understands the search query.

Although it might look like a universal solution to finding a better way to handle digital data, this technology is probably supposed to be only used for permanent archiving of data, not rewriting (I’ve never found a single mention of rewritable discs on Mempile’s homepage) which rather limits it’s practical use. Also, when storing such a vast amount of data on a single medium, you could soon regret it if the disc got scratched or damaged in some other way. However, it’s still a great deal to have a medium with 1 TB capacity, even if not rewritable. Besides, in the future, when the technology develops even more, the capacity of TeraDiscs should eventually reach up to 5 TB.

This invention appears to be a nice breakthrough in 3D data storage technology but I’m still convinced that it’s only a necessary part of transition which I’m waiting for. I mean who wants to use discs that get easily damaged when not handled properly…

In my opinion, datacubes are to replace discs as we know them in the near future for the purpose of storing digital data 3-dimensionally. Does it sound too much like sci-fi ? Just like internet at the beginning of 19th century ?
