System Architecture

You can now store and update multiple applications on a single resource-constrained device, while retaining the highest certification levels of compatibility.

Java Card is a smart card that is capable of running programs written in Java. For this new Java platform, Sun's JavaSoft division has made available the Java Card 2.0 API specification, and several licensees are now implementing this API on smart cards. In order to program Java Cards that are 2.0-compliant, developers need to understand what a Java Card is architecturally, what its core classes are, and how to develop applications for the card. The previous articles in the Java Developer series on smart cards provided an overview of smart cards, described how to deploy applications that talk to a Java Card using OpenCard interface, and discussed the business opportunities represented by the Java Card. This article gets inside a Java Card, providing you, the developer, with technical guidance on the system architecture, application programming interface, and runtime environment of the Java platform in a smart card.

This series of posts looks at the evolution of Open Networking & how it became what it is today. In this post, we will start with the Infrastructure domain.

This series of posts looks at the evolution of Open Networking & how it became what it is today. In this post, we discuss the enablers of Cloud Computing.

Part 2 of our series on Open Networking: The three domains of Open Networking. A top-level presentation of Aptira’s holistic view of Open Networking

Search for a definition of Open Networking & you’ll get a variety of answers. At Aptira, we have a much more holistic & inclusive definition.

To learn more about the origins of “The Network is the Computer,” I spoke with John Gage, the creator of the phrase and the 21st employee of Sun Microsystems. John had a key role in shaping the vision of Sun and had a lot to share about his vision for the future.

Today, the old Sun Microsystems tagline rings truer than ever. In our cloud-centric world, perhaps computers don't exist at all anymore.

Containerized workloads have long become the de facto standard deployment model for enterprise applications. However, there is still some…

With the recent demise of several popular "proxy" services that let cybercriminals route their malicious traffic through hacked PCs, there is now something of a supply chain crisis gripping the underbelly of the Internet. Compounding the problem, several remaining malware-based…

The “Sleng Teng” riddim revolutionized reggae music in the mid-1980s, and has spawned hundreds of versions in the decades since then. Less well known is the story of how the distinctive bassline or…

Some of my earliest childhood memories involve watching grainy VHS movies over and over on a huge 80’s floor model TV. Over the years there have been many format wars – Betamax vs VHS w…

SaaS platform Ezako’s commitment to improving machine learning on time series data significantly accelerates key processes that ML data scientists face.

There's a three-step process for transitioning to a multi-cloud strategy, and cloud resource optimization can help you make the move.

Cloud computing isn’t going anywhere, but some companies are shifting their machine learning data and models to their own machines they manage in-house. Adopters are spending less money and getting better performance.

In case you missed it, we’re living in the age of API insecurity. Gartner predicts that API breaches will become the leading attack vector in 2022. You don’t need to look far to read about how an API security flaw led to massive attacks against organizations like LinkedIn, Parler and Clubhouse. As APIs are becoming […]
