Apple Unveils Mac OS X

Next Generation OS Features New “Aqua” User Interface

MACWORLD EXPO, SAN FRANCISCO

January 5, 2000

Reasserting its leadership in personal computer operating systems, Apple® today unveiled Mac® OS X, the next generation Macintosh® operating system. Steve Jobs demonstrated Mac OS X to an audience of over 4,000 people during his Macworld Expo keynote today, and over 100 developers have pledged their support for the new operating system, including Adobe and Microsoft. Pre-release versions of Mac OS X will be delivered to Macintosh software developers by the end of this month, and will be commercially released this summer.

“Mac OS X will delight consumers with its simplicity and amaze professionals with its power,” said Steve Jobs, Apple’s iCEO. “Apple’s innovation is leading the way in personal computer operating systems once again.”

The new technology Aqua, created by Apple, is a major advancement in personal computer user interfaces. Aqua features the “Dock” — a revolutionary new way to organize everything from applications and documents to web sites and streaming video. Aqua also features a completely new Finder which dramatically simplifies the storing, organizing and retrieving of files—and unifies these functions on the host computer and across local area networks and the Internet. Aqua offers a stunning new visual appearance, with luminous and semi-transparent elements such as buttons, scroll bars and windows, and features fluid animation to enhance the user’s experience. Aqua is a major advancement in personal computer user interfaces, from the same company that started it all in 1984 with the original Macintosh.

Aqua is made possible by Mac OS X’s new graphics system, which features all-new 2D, 3D and multimedia graphics. 2D graphics are performed by Apple’s new “Quartz” graphics system which is based on the PDF Internet standard and features on-the-fly PDF rendering, anti-aliasing and compositing—a first for any operating system. 3D graphics are based on OpenGL, the industry’s most-widely supported 3D graphics technology, and multimedia is based on the QuickTime™ industry standard for digital multimedia.

At the core of Mac OS X is Darwin, Apple’s advanced operating system kernel. Darwin is Linux-like, featuring the same Free BSD Unix support and open-source model. Darwin brings an entirely new foundation to the Mac OS, offering Mac users true memory protection for higher reliability, preemptive multitasking for smoother operation among multiple applications and fully Internet-standard TCP/IP networking. As a result, Mac OS X is the most reliable and robust Apple operating system ever.

Gentle Migration

Apple has designed Mac OS X to enable a gentle migration for its customers and developers from their current installed base of Macintosh operating systems. Mac OS X can run most of the over 13,000 existing Macintosh applications without modification. However, to take full advantage of Mac OS X’s new features, developers must “tune-up” their applications to use “Carbon”, the updated version of APIs (Application Program Interfaces) used to program Macintosh computers. Apple expects most of the popular Macintosh applications to be available in “Carbonized” versions this summer.

Developer Support

Apple today also announced that more than 100 leading developers have pledged their support for the new operating system, including Adobe, Agfa, Connectix, id, Macromedia, Metrowerks, Microsoft, Palm Computing, Quark, SPSS and Wolfram (see related supporting quote sheet).

Availability

Mac OS X will be rolled out over a 12 month period. Macintosh developers have already received two pre-releases of the software, and they will receive another pre-release later this month—the first to incorporate Aqua. Developers will receive the final “beta” pre-release this spring. Mac OS X will go on sale as a shrink-wrapped software product this summer, and will be pre-loaded as the standard operating system on all Macintosh computers beginning in early 2001. Mac OS X is designed to run on all Apple Macintosh computers using PowerPC G3 and G4 processor chips, and requires a minimum of 64 MB of memory.

Choosing Between SMPP and HTTP APIs for SMS Integration

Decoding the Secrets Behind SMS Protocols: SMPP vs. HTTP APIs

In today's fast-paced digital landscape, seamless communication is essential for businesses aiming to connect with their customers effectively. Two dominant protocols facilitate this, each with its unique strengths and use cases: SMPP (Short Message Peer-to-Peer) and HTTP APIs. Understanding the technical differences between these protocols can help organizations choose the right solution for their messaging needs.

At a high level, SMPP is a protocol originally designed for high-volume, reliable messaging between short message service centers (SMSCs) and external systems. It operates over TCP/IP and provides a low-latency, high-throughput environment suitable for bulk messaging. SMPP's architecture allows for detailed control over message delivery, delivery reports, and incoming messages, making it a favorite among large enterprises and telecom operators.

On the other hand, HTTP APIs are web-based interfaces that leverage standard HTTP protocols to send and receive SMS messages. They are easier to implement, typically requiring less setup and configuration, and are highly accessible for developers familiar with RESTful services. HTTP APIs are ideal for small to medium-sized businesses or applications that need quick integration without the complexity of traditional telecom protocols.

The Inner Workings of SMPP and HTTP APIs

SMPP functions as a messaging protocol that facilitates communication between external systems and SMSCs. It uses a binary protocol that can handle high volumes of messages with minimal latency. SMPP supports multiple message types, including text, binary, and Unicode, and offers features like message segmentation, delivery receipts, and session management. Its architecture is designed for stability and efficiency in high-demand environments, often requiring dedicated servers and specialized knowledge to implement.

HTTP APIs, by contrast, operate over the standard web infrastructure. They typically provide RESTful endpoints where developers can send POST requests containing message payloads. The server processes these requests and communicates with the SMSC or carrier network to deliver the message. HTTP APIs excel in simplicity and scalability for cloud-based applications, offering features like message status callbacks, user authentication, and detailed reporting.

Performance and Reliability Considerations

Choosing between SMPP and HTTP APIs often hinges on performance requirements. SMPP's low latency and high throughput capabilities make it suitable for bulk messaging campaigns, alerts, and critical notifications where delivery speed is paramount. Its persistent connection model ensures reliable delivery, but it also demands rigorous maintenance and monitoring.

HTTP APIs, while generally less performant in raw speed, offer the advantage of easy scalability and integration. They are well-suited for applications that prioritize rapid deployment and flexibility over ultra-high throughput. Modern HTTP APIs also support features like queued messaging and delivery reports, enhancing reliability for most use cases.

Security and Compliance Aspects

Security is a vital concern in SMS communication. SMPP connections typically employ SSL/TLS encryption to secure data transmission, and proper authentication mechanisms are essential to prevent unauthorized access. Its complexity means that organizations need to implement robust security practices and network monitoring.

HTTP APIs, being web-based, often incorporate OAuth tokens, API keys, and HTTPS encryption to safeguard data. Their simplicity allows for easier compliance with industry standards and regulations, especially in cloud environments where security protocols are managed by the service provider.

Integration Challenges and Developer Experience

Implementing SMPP can be challenging due to its binary protocol and the need for specialized knowledge in telecom signaling. It often requires dedicated infrastructure, such as SMPP servers, and ongoing maintenance.

HTTP APIs, however, are designed for ease of use. Most developers are familiar with RESTful APIs and JSON payloads, reducing the learning curve and accelerating deployment timelines. This accessibility makes HTTP APIs particularly attractive for startups and organizations seeking quick integration.

Choosing the Right Protocol for Your Business

The decision between SMPP and HTTP APIs depends on your organization's specific needs. For high-volume, mission-critical messaging that demands maximum control and reliability, SMPP remains the gold standard. Conversely, for rapid deployment, scalability, and ease of integration, HTTP APIs offer a compelling solution.
