Plotting for science

Not so long ago, the typical science or research lab was filled with large, heavy instruments, each designed to do just one thing. Now scientists, engineers, and amateurs alike can download lab-grade instruments for free. For example, there's SigmaGraph, a free plotting and analysis tool from SIDI. It offers scientific graphing, curve fitting, editable data sheets, drawing tools, a scripting engine, and more.

SigmaGraph consists of three parts: the SigmaConsole, a mathematical tool that's sort of like a tiny virtual blackboard; the SigmaGraph interface, with a typical Windows layout; and the SigmaTray icon, which resides in the System … Read more

Would e-mail transform Facebook, or vice versa?

Facebook has overcome plenty of challenges and defied plenty of detractors in its ascent to Internet power. It looks likely to take on a new set of both Monday with an expected new e-mail service.

ZDNet blogger Mary Jo Foley published word of the expected Facebook e-mail service yesterday, along with the possibility that Facebook will integrate it with Microsoft's online Office tools. And today, TechCrunch also said Facebook will unveil its e-mail service, called Titan. Facebook's invitation, styled like an air mail envelope, suggests there's truth to the reports.

E-mail is in many ways a natural … Read more

File download speed test

Febooti's fileTweak Download Speed is a small, specialized utility that clocks your download speed, compares it with standard connection types, and estimates how long it would take to download a specified file via various connections. It integrates with the Windows file properties dialog, too, so it's handy yet unobtrusive. It basically does what those broadband speed test Web sites do, only hosted on your PC. It's a module of the developer's fileTweak utility, but we tested the standalone freeware version.

Although this compact tool is no bigger than the average portable application, it downloads and installs … Read more

Facebook's Open Graph going mobile

SAN FRANCISCO--Facebook's Open Graph is the reason there are Facebook "Like" buttons strewn across the Web on sites that Facebook doesn't operate. Eric Tseng, Facebook's head of mobile products and a former product manager of the Google Nexus One phone, told the room at MobileBeat 2010 that Open Graph is going mobile.

What does this mean? Simply that as Facebook rolls out its Open Graph plug-ins to partners in the mobile space, many more of Facebook's social tools (such as that "Like" button, for instance) will show up in unrelated mobile apps … Read more

Scribd gets 'Readcasting': Autosharing made easy

Document-sharing site Scribd has a new trick up its sleeve that will make whatever you're viewing on the site a little more public. That is, if you feel like broadcasting your reading habits to the world.

The new feature is called Readcasting, and it's an evolution of the social-sharing options found on most sites. You can set the site to post your reading activity to Facebook and Twitter. That's pretty standard, though. Not standard: once you've set your log-ins for each network, there's an option to have Scribd automatically share what you're reading with … Read more

Facebook opens chat, and AIM plugs in

Correction 1:05 p.m. PST: Boy, did I get it wrong.

Writing off available information this morning--the AIM beta download site and a few news reports--I assumed the Facebook-AOL interoperability was the result of a corporate partnership. Instead, it's because Facebook actually did open up its technology, embracing rather than neglecting the approach I called for. In this case at least, the bad instant messaging network habits from the past were not carried over.

I have to say I'm impressed with Facebook's move, and not because it makes the crow I'm eating any tastier. What … Read more

ActiveX-tra

AsdGraph3D Pro Excel Addin gives you the capability to create three-dimensional graphs with data from Excel spreadsheets. These 3D graphs can also plot ActiveX controls that can be used in programs such as Microsoft Office and Internet Explorer.

The 3D graphs this add-in produces aren't flashy and would be best used for programming purposes rather than for design or illustrations. Graphic design experience left us unimpressed with the look of the graphs that the program produces; however, from a programming perspective, they're quite sufficient. There's a good built-in Help file that explains the program's controls and … Read more

Put Task Manager in Windows' notification area

The icons that reside in the Windows notification area (near the clock in the taskbar) convey much useful information at a glance. Is my network link live? How's my notebook's battery? Is there really yet another Windows update ready to be installed?

But one bit of information I often want to know is how much of my CPU is in use at any given time. Now the notification area gives me the lowdown on my processor as well. All I did was add a Task Manager shortcut to Windows' start-up folder and set the shortcut to open minimized.… Read more

Vertigo-inspiring graphics

Swan Studios' 3D Graph Generator is an innovative program for creating animated three-dimensional graphs. Used responsibly, this software makes memorable and informative graphs that will give your presentations a professional appeal. If you're not careful, though, you'll need to pass out motion sickness bags at your next sales meeting.

The program's interface is fairly intuitive, although the Options menu, where the graph configuration takes place, is a bit confusing at first glance. The built-in Help file is brief but adequate. The program's sample data gives an immediate look at what's in store, and we quickly … Read more

Free map maker

StatPlanet Map Maker provides a simple set of tools for creating a detailed map. While the main function was more tedious than we originally hoped, the results were still useful in the right situation.

The program's interface is simple to grasp, and its controls are intuitive. StatPlanet Map Maker's layout reminds us of pop-up maps we've seen on news Web sites. The program also includes an extensive User's Manual, which is helpful for inputting your own data. It gives you full control over your map view, with options such as choosing to view the entire planet … Read more
