Lecture# 7 midi file format
The document discusses MIDI (Musical Instrument Digital Interface), which allows musical instruments and devices to communicate. It describes MIDI's components like synthesizers, sequencers, tracks, channels, and messages. MIDI provides a low-bandwidth way to transmit musical data and sound effects over the web by moving sound production to the client. It can be used to synchronize devices and convey musical performance data for applications like multimedia, games, and karaoke.
working principle of midi-interface
MIDI (/ˈmɪdi/; an acronym for Musical Instrument Digital Interface) is a technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing, and recording music.[1] The specification originates in a paper titled Universal Synthesizer Interface, published by Dave Smith and Chet Wood, then of Sequential Circuits, at the October 1981 Audio Engineering Society conference in New York City.[2]

The document summarizes the basic components of a computer system including input, processing, storage, and output devices. It describes common input devices like keyboards, pointing devices, scanners, and cameras. It then explains processing units like the CPU and microprocessor. Storage devices covered include hard drives, floppy drives, removable disks, and CD-ROM drives. Finally, it lists the main output devices as monitors, printers, and speakers.
Slides input devices
The document discusses input devices and their functions. It defines input as any data or instruction entered into a computer's memory. There are four main types of input: text, audio, graphic, and video. Input devices are electronic devices connected to a computer that produce input signals. Examples of input devices include keyboards and mice for text, microphones and MIDI keyboards for audio, scanners and digital cameras for graphics, and webcams and digital video cameras for video. The objective is for students to understand the meaning and functions of different input devices.
New Identifying The Hardware System Components
The document identifies the hardware system components in a classroom including three data sources, three video sources, and three audio sources. The data sources are a LAN/high-capacity PC, laptop computer, and document camera. The video sources are a 35mm slide-to-video converter, DVD player, and S-VHS deck. The audio sources are a gooseneck microphone, stereo speakers, and the DVD player. All of the components are mounted in the lectern or on an equipment rack in the closet and are used to display, play, and output data, video, and audio.
Chapter 4 : SOUND
Sound is created by vibrations that travel through a medium like air as sound waves. It has two main characteristics - frequency determines pitch, and amplitude determines loudness. Digital audio involves sampling an analog sound wave into discrete numeric samples at a certain rate. MIDI data provides instructions for synthesizing music rather than storing actual sound samples. When adding audio to multimedia projects, the file format, playback capabilities, and intended function of the sound must be considered.
Midi message formats
MIDI messages are made up of status and data bytes. The status byte indicates the type of message and data bytes provide additional details. Common MIDI messages include Note On/Off to play notes, Controllers to control parameters, and Program Changes to switch presets. MIDI allows connection of multiple devices in daisy chains with different channel and mode settings to route messages.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

National Security Agency - NSA mobile device best practices
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.
“I’m still / I’m still / Chaining from the Block”
“An Outlook of the Ongoing and Future Relationship between Blockchain Technologies and Process-aware Information Systems.” Invited talk at the joint workshop on Blockchain for Information Systems (BC4IS) and Blockchain for Trusted Data Sharing (B4TDS), co-located with with the 36th International Conference on Advanced Information Systems Engineering (CAiSE), 3 June 2024, Limassol, Cyprus.
Artificial Intelligence for XMLDevelopment
In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

Computer devices
- 2. Types of computer devices Input Devices Output Devices Storage Devices
- 3. Input Devices Input devices are those devices which provides input data to computer. For Example 1. Key Board 2. Microphone
- 4. Keyboard It is an input device to give computer some input. It is like pen in writing. It is called keyboard because it is comprised of a board with keys installed. Every key sends unique information to the computer.
- 5. Microphone Microphone is used to input the sound to computer. It is used in motion pictures, radio and television broadcasting etc.
- 6. Output devices Those devices which take the data out from the computer. For example 1. Monitor 2. Speakers
- 7. Monitor Computer’s screen which displays the data.
- 8. Speakers Speakers take the aural data from the computer.
- 9. Storage Devices Process of storing information in computer is called storage. The devices used to store data are called storage devices. For Example 1. DVD 2. Magnetic tape
- 10. DVDs DVD stands for digital versatile disk. It was invented to store video only that is why previously it was called as a digital video disk. Its capacity is much greater.
- 11. Magnetic tape It is like an audio cassette. Data is saved in line. Data saved first would be read first. It has huge storage capacity. Keep it away from magnet to save from damage. This Photo by Unknown Author is licensed under CC BY-NC-ND
