Chrome DevTools: The Indispensable Toolkit for Interrogating Web Page Data

Inspecting application data has evolved a bit since the 5250 green-screen days.

robert swansonWritten by Robert Swanson

There once was a time in the midrange computing world when developers tasked with tracing the source of data showing on a particular application screen could follow a fairly rote process to identify it. With the primary interface being a 5250 green-screen, the developer could start by locating the DDS display file for the underlying screen, use SDA to find the appropriate record format and field name(s), and then look at the associated RPG code to see how those particular display fields are populated. He or she could then begin making program adjustments as needed.

How Regulatory Agencies Affect Social Media Guidelines

Or why there's no excuse for not including that disclaimer in a 140-character Tweet.

bill riceWritten by Bill Rice

After a meeting of the Board, the CFO of a prominent clothing retailer sent an upbeat and seemingly harmless tweet from his private Twitter account: "Board meeting: Good numbers=Happy Board." One problem: Official earnings hadn't yet been released to all investors, so the CFO's Twitter followers were now privy to insider information, and the CFO was quickly fired for "improperly communicating company information through social media."

Practical Integration: Mounting NFS Drives

FTP works everywhere, but it's not always the most practical solution; sometimes you just need to mount a drive.

joe plutaWritten by Joe Pluta

The more integrated the IBM i gets, the more ways it needs to touch other systems. Tools abound that allow us to stretch beyond the boundaries of traditional DB2 data into everything from XML to PDF to ZIP files. The IFS affords a wonderful place to store those files, but you can't just create them; eventually you have to share them with others. FTP is an old standby: simple yet extremely flexible. Email is another popular approach. But today we're going to learn about something just a little sleeker. Welcome to the world of Network File System (NFS) files!

Is 2014 the Internet's Last Good Year?

Without our input, the Internet's fate is left to the whim of career politicians, lobbyists, and marketing departments.

roger penceWritten by Roger Pence

The destiny of the Internet as we know it today hangs on the fate of Net neutrality. I'll dig into some of the basics of Net neutrality in this article (with mostly fact but a few closing opinions), but before that, let's go back in time.

What's New in Machine-Readable Technologies

While the technologies enabling machine-readable data are momentarily stable, ideas for capitalizing on existing technologies are exploding.

john gristWritten by John Ghrist

"Machine-readable" technology, by definition, has been around since Thomas Edison gave us the phonograph record. In recent years, we've come to think of this field as being dominated by optical-character recognition (OCR) for scanning standard documents, magnetic-ink character recognition (MICR) for checks and financial papers, and radio-frequency identification (RFID) for tracking the locations of goods and objects. However, the whole field encompasses the concept of automatic identification (AID), the process of helping machines identify objects, capturing data about those objects, and making that information available as data without requiring manual data-entry procedures. This definition can include such objects as smart cards and such technologies as biometrics. It also includes ways of letting common terms be "synchronized" in their meaning throughout related data sets.

What Are Fabric Data Networking Devices, and What Do They Offer?

Are they really the future of the Internet?

tom stockwellWritten by Thomas M. Stockwell

The Internet continues to evolve in ways that its founders had not initially anticipated. Yet we take for granted that its evolutionand the resources that drive itwere all part of some master plan of efficiency and transparency. Unfortunately, this is not the case. For instance, consider how this page that you are currently reading has arrived on your computer screen or on your tablet or phone. It was assembled on the fly from a variety of elements referenced from multiple servers that exist at numerous physical locations.

Taming the "Wild West" That Is TCP/IP

Are you sure you're properly securing your IP applications?

mike faustWritten by Mike Faust

If your IBM i is running TCP/IP, you have a problem. While the availability of IP applications is a blessing in that it gives your company an easy way to access your systems based on a set of defined standards, it also gives hackers an easy way to get into your systems and data using defined standards. Utilizing secure IP connectivity for your Telnet, FTP, and HTTP connectivity can help to curb the problem, but what about all of those other IP applications?

Creating an Interactive Information Screen in a Browser: Is It Possible?

You can build your own stable, modern, and easy-to-maintain information platform.

jan jorgensenWritten by Jan Jorgensen

Users want stable applications that just run and run. On the IBM i, it's not very hard to give them that, but they also want applications that look good, with fancy colors, pictures, and fonts. And they want combined information. Some information comes from the i, some from the SQL database, and some from a text file. And pictures are stored on Web servers around the world. How are you supposed to be the provider of all this?
