This document discusses object-oriented programming (OOP) and file input/output in C++. It describes how files can be accessed sequentially or randomly. Random access files allow records to be accessed in any order, while sequential files require processing records in sequence. The document also provides code examples for creating and writing text files, reading files with characters and strings, and reading/writing binary files with user-defined class objects.

The Node.js file system module allows you to work with the file system on your computer. Node.js gives the functionality of File I/O by providing wrappers around the standard POSIX functions. In Node.js, File I/O methods can be performed in both synchronous as well as asynchronous form depending upon the user requirements.
There are number of players that provide full text search feature, starting from embedded search to dedicated search servers [solr, sphinx, elasticsearch etc], but setting up and configuring them is a time consuming process and requires considerable knowledge of the tools.
What if we could get comparable search results using full text search capabilities of Postgres. Developers already have the working knowledge of the database, so this should come natural. In addition to that, it will be one less tool to manage.

An overview and discussion on indexing data in Redis to facilitate fast and efficient data retrieval. Presented on September 22nd, 2014 to the Redis Tel Aviv Meetup.
FSter is the first component we (itsme) are releasing to the development community, as an essential part of Guglielmo that might be reused by other projects and applications with similar needs: you can get it from here.
FSter is a virtual file system implementation based on Fuse technology and exploiting Tracker metadata technology to allow access to files according to the metadata they’re associated to. Practically, FSter enables scenarios such as the following ones:
* browsing the content of a drive (or simply of a folder) according to a user-defined hierarchy or progression of filters based on metadata;
* associating metadata to files whenever operations are performed on them. For example, copying or saving a file in a specific place means storing it along with a description (metadata);
* generating “virtual” files from metadata, e.g., a vCard file that is not really on the file system, but dynamically built from metadata.
In order for you to be able to install, use, and extend FSter, or to contribute in any other way, we have set up some tools online:
* a wiki where you can find detailed information on the project, descriptions and instructions: http://gitorious.org/itsme/pages/Fster
* a bug reporting system (i.e., Bugzilla) where you can file any problem you find in our software: http://bugs.itsme.it
* a mailing lists system where you can subscribe to discussions and interact with us and other developers: http://lists.itsme.it
* an IRC channel where you will find (most of) the itsme technical staff all day long (well, Italian time mainly – i.e., GMT +1): #itsme-dev on irc.freenode.net

Pioneers of Information Science in Europe: The Oeuvre of Norbert HenrichsWolfgang Stock
In this presentation we discuss the works and influence of Norbert Henrichs (born 1935), a pioneer of Information Science in Europe. In the context of philosophy documentation, Henrichs developed in the 1960s a dictionary-independent method of indexing: the Text-Word Method. This method works exclusively with the term material of the documents to be indexed. It starts by using a variant of syntactic indexing, viz. the formation of thematic chains. Documents indexed via the Text-Word Method form the basis for relatively ballast-free information retrieval, but also for studies in the history of ideas. Henrichs was a leading contributor to the formulation and realization of the German Information & Documentation (I&D) program (1974 – 1977). This widely noted political program planned for the world’s entire scientific and technical literature to be made available in 20 specialized information centers. Henrichs served as scientific executive director of the central German infrastructure provision within the I&D program, the “Society for Information and Documentation” (GID), from 1980 to 1985. Over the course of the 1980s, the I&D program broke down—mainly due to a lack of financing. At the Heinrich-Heine-University in Düsseldorf, Henrichs successfully developed a curriculum for information science, which—typically for Germany in the 1980s and 1990s—had no strong ties to either library science or computer science.

RuleML2015: Explanation of proofs of regulatory (non-)complianceusing semanti...RuleML
With recent regulatory advances, modern enterprises have to not only comply with regulations but have to be prepared to provide explanation of proof of (non-)compliance. On top of compliance checking, this necessitates modeling concepts from regulations and enterprise operations so that stakeholder-specific and close to natural language explanations could be generated. We take a step in this direction by using Semantics of Business Vocabulary and Rules to model and map vocabularies of regulations and operations of enterprise. Using these vocabularies and leveraging proof generation abilities of an existing compliance engine, we show how such explanations can be created. Basic natural language explanations that we generate can be easily enriched by adding requisite domain knowledge to the vocabularies.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

3. Files
• A file is a collection of data in mass storage.
• A data file is not a part of a program’s source
code.
• The same file can be read or modified by
different programs.
• The program must be aware of the format of
the data in the file.
4. Files (cont’d)
• The file system is maintained by the
operating system.
• The system provides commands and/or GUI
utilities for viewing file directories and for
copying, moving, renaming, and deleting
files.
• The system also provides “core” functions,
callable from programs, for reading and
writing directories and files.
8. Sequential Files
Sequential file techniques provide a straightforward way to read and write
files. Basic's sequential file commands manipulate text files: files of ASCII
characters with carriage-return/linefeed pairs separating records.
In computer science, sequential access means that a group of elements (e.g.
data in a memory array or a disk file or on a tape) is accessed in a
predetermined, ordered sequence. Sequential access is sometimes the only
way of accessing the data, for example if it is on a tape. It may also be the
access method of choice, for example if we simply want to process a
sequence of data elements in order.
9. Random Access Files
Random access files consist of records that can be accessed in any sequence.
This means the data is stored exactly as it appears in memory, thus saving
processing time (because no translation is necessary) both in when the file is
written and in when it is read.
In computer science, random access (sometimes called direct access) is the
ability to access an arbitrary element of a sequence in equal time.
10. Random-Access Files
• A program can start reading or writing a
random-access file at any place and read or
write any number of bytes at a time.
• “Random-access file” is an abstraction: any
file can be treated as a random-access file.
• You can open a random-access file both for
reading and writing at the same time.
11. Random-Access Files (cont’d)
• A binary file containing fixed-length data
records is suitable for random-access
treatment.
• A random-access file may be accompanied
by an “index” (either in the same or a
different file), which tells the address of each
record.

14. Random Access Files
A RandomAccessFile employs an internal pointer that points to the next
byte to read.
This pointer is zero-based and the first byte is indicated by index 0.
When first created, a RandomAccessFile points to the first byte.
You can change the pointer's position by invoking the different methods.
The skipBytes method moves the pointer by the specified number of
bytes.
If offset number of bytes would pass the end of file, the internal pointer
will only move to as much as the end of file.
16. "r". Open for reading only.
"rw“. Open for reading and writing.
If the file does not already exist, Random Access
File creates the file.
"rws". Open for reading and writing and require that every
update to the file's content and metadata be written
synchronously.
"rwd". Open for reading and writing and require that every
update to the file's content (but not metadata) be
written synchronously.
