Welcome to Operating Systems: Three Easy Pieces (now version 1.00 -- seebook news for details), a free online operating systemsbook! The book is centered around three conceptual pieces that arefundamental to operating systems: virtualization, concurrency, and persistence. In understanding the conceptual, you will also learn thepractical, including how an operating system does things like schedule theCPU, manage memory, and store files persistently. Lots of fun stuff! Ormaybe not so fun?

PROJECTS: While the book should provide a good conceptual guide to keyaspects of modern operating systems, no education is complete withoutprojects. We are in the process of making the projects we use at theUniversity of Wisconsin-Madison widely available; an initial link to projectdescriptions is available here:PROJECTS. Comingsoon: the automated testing framework that we use to grade projects.
Bigtable is a distributed storage system for managing structured data that is designed to scale to a very large size: petabytes of data across thousands of commodity servers. Many projects at Google store data in Bigtable, including web indexing, Google Earth, and Google Finance. These applications place very different demands on Bigtable, both in terms of data size (from URLs to web pages to satellite imagery) and latency requirements (from backend bulk processing to real-time data serving). Despite these varied demands, Bigtable has successfully provided a flexible, high-performance solution for all of these Google products. In this paper we describe the simple data model provided by Bigtable, which gives clients dynamic control over data layout and format, and we describe the design and implementation of Bigtable.
Patient navigation programs have shown to be effective across multiple settings in guiding patients through the care delivery process. Limited experience and literature exist, however, for such programs in rural and resource-constrained environments. Patients living in such settings frequently have low health literacy and substantially lower social status than their providers. They typically have limited experiences interfacing with formalized healthcare systems, and, when they do, their experience can be unpleasant and confusing. At a district hospital in rural far-western Nepal, we designed and implemented a patient navigation system that aimed to improve patients' subjective care experience. First, we hired and trained a team of patient navigators who we recruited from the local area. Their responsibility is exclusively to demonstrate compassion and to guide patients through their care process. Second, we designed visual cues throughout our hospital complex to assist in navigating patients through the buildings. Third, we incorporated the patient navigators within the management and communications systems of the hospital care team, and established standard operating procedures. We describe here our experiences and challenges in designing and implementing a patient navigator program. Such patient-centered systems may be relevant at other facilities in Nepal and globally where patient health literacy is low, patients come from backgrounds of substantial marginalization and disempowerment, and patient experience with healthcare facilities is limited.
Unlike most language specifications, reading systems must use the container root URL asthe base URL [url] for all files within theMETA-INF directory. See also the section on Parsing URLs in the META-INFdirectory in [epub-33].
Although EPUB creators are required to follow various file name and file path restrictions[epub-33] for maximum interoperability, reading systems SHOULD attempt to process file namesand paths that do not adhere to these requirements. Invalid file names and paths may only beproblematic on some operating systems.
To determine whether the value of a dc:identifier element [epub-33] conforms to anestablished system or has been granted by an issuing authority, reading systems SHOULD checkfor an identifier-type property[epub-33].
When manifest fallbacks [epub-33] are providedfor top-level content documents, reading systems MAY choose from the available options to findthe optimal version to render in a given context (e.g., by inspecting the properties attribute foreach).
The definition of EPUB content documents [epub-33] includesvarious authoring restrictions to optimize the cross-compatibility of content (e.g., prohibiting CSS for setting language and direction[epub-33]). Unless stated otherwise in this specification, reading systems MAY support theserestricted features.
To limit the possible damage of untrusted scripts, this specification recommends that readingsystems establish a unique origin [html] allocated to eachEPUB publication (see 4.1.1 URL of the root directory). Assigning a unique origin ensuresthat spine-level scripts [epub-33] are isolatedfrom other EPUB publications, and limits access to cookies [html], web storage [html], etc.
Reading systems MUST create the initialcontaining block (ICB) using the width and height expressions declared in theviewport meta tag for XHTML content documents, as defined in Expressing in HTML [epub-33].They MUST clip contentpositioned outside of the ICB.
This specification does not define a default rendering behavior when reading systems do notsupport this property or EPUB creators do not specify it. Reading systems MAY render spineitems by their own design.
When presented with a media overlay text element [epub-33] whose src attributecontains a URL-fragment string referencing a specific part of an EPUB content document,reading systems SHOULD ensure the referenced portion is visible in the viewport. In additionto [html] element ID references and SVG FragmentIdentifiers [svg], reading systems MAY support other fragment identifier schemes.
While playing media overlays, reading systems SHOULD offer usersthe option to leave ("escape") escapablestructures [epub-33], which are determined by the presence of an epub:typeattribute [epub-33] with a value from the escapable structures list.If a user opts to escape from an escapable structure, then thereading system MUST continue playback with the next sequential element after thestructure.
Reading systems that do not support the [epub-33] vocabulary association mechanisms MAY processproperty values as plain string values [infra]. It is not required to support theexpansion of these values to URLs to add reading system behaviors based on their presence.
The greatest threats to users come from the content theyread [epub-33], and the first line of defense against these attacks is the reading systemsthey use. Users expect that reading systems act as safeguards against malicious content and areoften unaware that EPUB publications are susceptible to the same security risks as websites.
EPUB publications may contain resources designed to exploit security flaws in readingsystems or the operating systems they run on. Attackers may also try to gain access toremote resources using file indirection techniques, such as symbolic links or filealiases.
This specification does not define an epubReadingSystem property extension for theWorkerNavigator object [html]. Reading systems therefore do not have to expose theepubReadingSystem object in the scripting context of Workers, and EPUB creators cannot rely on its presence.
Project Oberon contains a definition of the Oberon Language and describes its relation to Modula-2 and the software tools developed with the system. This definitive, first-hand account of the design, development, and implementation of Oberon completes the Oberon trilogy.
Author: Paul SandersonPublisher: AmazonThis text by noted digital forensics expert, Paul Sanderson, providesinvestigators with low-level technical details useful in analysingSQLite database files.Every computer and phone uses hundreds of SQLite databases and there areover one trillion SQLite databases in active use. Hence, the importanceof examining the data held in these databases in aninvestigation, including deleted data when possible, is paramount. Thisbook fully explains the format of the SQLite database file. It shows howrecords are encoded, how to decode them manually and how to decoderecords that are partially overwritten. It also describe how theworkings of SQLite, and in particular the journal and WAL, can be usedto ascertain what has happened in a manner that cannot be determinedfrom the data alone. The book covers basic SQL queries and how they canbe used to create a custom report that includes data from differenttables, and shows how one can use SQL queries to test hypotheses aboutthe relationships of data in different tables. This book is aimed mainly atforensic practitioners, and it is assumed that the reader has some basicknowledge of computer forensics; it will also be of interest to computerprofessionals in general particularly those who have an interest in theSQLite file format.Learning SQLite for iOS (2016)Author: Gene Da RochaPublisher: Packt PublishingThis book starts with the architecture of SQLite database and introducesyou to concepts in SQL.
