4D Summit 2016: Laurent Esnault presents workers and UI in preemptive mode

Automatically translated from English

Our own VP of Engineering, Laurent Esnault, explains exchanging information between multiple processes AND between processes and forms during his Break Out Session: Preemptive Multi-threading at 4D Summit 2016. Thanks to preemptive multi-threading, you can have more parallel processes, and thus add more and more users, for either desktop or web applications.

Tips Many thumbs up for the JSON Validator tool

A new tool: JSON Validator

Automatically translated from English

4D v16 R4 introduces a new command: JSON Validate. This command allows you to verify that a JSON document is “valid” according to your JSON schema. This is really useful for exchanging information between servers or between a server and its client. Thanks to JSON schema standards, you can define a “protocol” for communication with your server or an external server. More details can be found in this blog post.

Tips

Display your dashboard on a big TV screen

Automatically translated from English

Today, big screens are everywhere. At the airport or train station for arrival/departure. In production areas for failure/success or production numbers. In call centers for activity or calls in queue. In stock exchange for a ticker.

Your first thought could be to use a normal computer, macOS or Windows, with a “27” or 30” screen. Expensive, but easy to do. But besides the high price, you need to run a 4D app, launch it, update it, all just to display a picture?

How to use Google Charts with 4D

Automatically translated from English

According to neuroscientists, we respond better and faster to a visual form than any other type of representation. That’s why graphs and charts are clearly a key to a better understanding of data.

So if you’re looking to display bar charts, histograms, or pie charts which are modern and fully compatible with the leading browsers, but also more suitable for the way the human brain processes information, Google Charts is one possible answer. The available chart types in Google Charts is varied: from the classical bar/column/pie charts, Google Charts also offers elaborated graphs such as Treemap, Candlestick and Gauge charts.

Product Road to IPv6

Enhance IPv6-related user interface

Automatically translated from English

Besides the fact that it has a larger address space, IPv6 also has many other advantages over IPv4: built-in features like support of multicast transmission, increased security with IPSec (providing confidentiality, authentication and data integrity) and the ability to display, in the 4D client connection dialog box, all the 4D Server available even if they are published on a non standard port (different than 19813).

4D introduced IPv6 support with 4D v14, however some dialogs were not perfectly arranged for the IPv6 use cases. 4D v16 R4 provides some UI improvements for a better user experience for people using IPv6 network configurations.
