Adesso's Tubes simplifies peer-to-peer file sharing

Free client application lets users quickly and easily share and update the info they use every day

Adesso Systems this week released a free client application that lets users quickly and easily share and update the information they use every day, such as documents, PDF files, spreadsheets, photos and video clips.

Technically, Adesso Tubes is a simple-to-use data replication program that links with server software on an Adesso-hosted Web site. Tubes extends the core data replication technology that Adesso originally developed for the enterprise market. And the company plans to release a paid version of Tubes for enterprise users later this year. The initial version is aimed at what's called the social-networking market of networked consumers, individually and in groups.

Tubes represents a major shift for Adesso, a shift outlined in mid-2006 by Adesso Chairman, CEO and CTO John Landry, the former CTO of Lotus Development. Originally, he said, Adesso created a distributed database architecture, spanning multivendor databases, along with development tools to quickly build a range of client database applications. Transactional data added or changed at one database was automatically copied to the other databases over the network.

But users today rely on a vast quantity of information outside of traditional databases, and this information is difficult to track and share.

"The files created by programs like Excel, Word, PDF forms and so on, are the lingua franca of what people do today," Landry said in an interview then. "What if we linked the file system into our distributed database? The idea is that you just have distributed folders, and Adesso keeps them synchronized behind the scenes. The author can put into the folder an updated file, and everyone [with access to that folder] is using that updated version."

Tubes is the software that does this. It's a Windows application, based on the Microsoft .Net Framework, which users download from www.tubesnow.com to their PC. Using the Tubes Navigator panel, you create and label a "tube" that in effect connects everyone in a given group. You invite people to join the group by sending them an e-mail invitation, which they can accept or reject.

The tubes you create can be for and about anything: the soccer team you coach, family pictures, the corporate marketing department. Using an interface similar to Windows Explorer, you can drag and drop into a given tube any file from your PC desktop, including Web URLs, or from within an application like Outlook, such as e-mail or a VCard. Tubes creates a copy of the file on your hard drive, then replicates that file to the Adesso hosted server over an encrypted link. Tubes then notifies the members of the Tubes group of a new or updated file. Then it sends the new file to them, or just the changed information.

"We track on the server whatever you put in the tube, who put it in, with their designated roles, permissions and capabilities," says Steve Chazin, Adesso's vice president of marketing. "This is tracked on a per-file basis."

Members of the Tube group have different permissions. You can allow them to just read or view the files, or allow any number of them editing privileges. If you're receiving files from another Tube "owner" you can get an alert showing you what the file is and how large it is, so you can decide whether to receive it or not.

Windows 10 for Business / Dell XPS

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Windows 10 / HP Spectre

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Mark Escubio

Windows 10 / Lenovo Yoga

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
