Building Your Own Operating System: A Beginner’s Guide

An operating system (OS) is an essential component of computer systems, serving as an interface between hardware and software. It manages system resources, provides services to users and applications, and ensures efficient execution of processes. Without an OS, users would have to manually manage hardware resources, making computing impractical for everyday use.

Lightweight operating system for old laptops

Functions of an Operating System

Operating systems perform several crucial functions to maintain system stability and usability. These functions include:

1. Process Management

 The OS allocates resources to processes and ensures fair execution while preventing conflicts. It employs algorithms like First-Come-First-Serve (FCFS), Round Robin, and Shortest Job Next (SJN) to optimize CPU utilization and maintain system responsiveness.

2. Memory Management

The OS tracks memory usage and prevents memory leaks by implementing techniques such as paging, segmentation, and virtual memory. These mechanisms enable multitasking and improve overall system performance.

3. File System Management

It provides mechanisms for reading, writing, and deleting files while maintaining security through permissions and access control. File systems such as NTFS, FAT32, and ext4 are widely used across different operating systems.

4. Device Management

 The OS provides device drivers to facilitate interaction with hardware components like printers, keyboards, and network adapters. It ensures smooth data exchange and resource allocation for input/output (I/O) operations.

5. Security and Access Control

 It enforces authentication, authorization, and encryption mechanisms to protect user data and system integrity. Modern OSs incorporate features like firewalls, anti-malware tools, and secure boot processes to prevent unauthorized access and cyber threats.

6. User Interface

 CLI-based systems, such as Linux terminals, provide direct access to system commands, while GUI-based systems, such as Windows and macOS, offer intuitive navigation through icons and menus.

Types of Operating Systems

Operating systems come in various forms, each designed to cater to specific computing needs. Some common types include:

1. Batch Operating System

These systems were widely used in early computing environments for tasks like payroll processing and scientific computations.

2. Multi-User Operating System

 It ensures fair resource allocation and prevents conflicts between users. Examples include UNIX and Windows Server.

3. Real-Time Operating System (RTOS)

RTOS is designed for time-sensitive applications, where processing must occur within strict deadlines. It is used in embedded systems, medical devices, and industrial automation. Examples include VxWorks and FreeRTOS.

4  Mobile Operating System

Mobile OSs are tailored for smartphones and tablets, offering touchscreen interfaces and app ecosystems. 

5  Distributed Operating System

Distributed OS manages multiple computers as a single system, enabling resource sharing and parallel processing. It is used in cloud computing and supercomputing environments. Examples include Google’s Fuchsia and Amoeba.

Popular Operating Systems

Several operating systems dominate the computing landscape, each catering to specific user needs and hardware platforms.

1. Microsoft Windows

 It is popular among home users, businesses, and gamers. Windows 10 and 11 are the latest versions, offering improved performance, security, and compatibility.

Snapchat?

Snapchat is an American multimedia instant messaging app and service developed by Snap Inc., originally Snapchat Inc. One of the principal features of Snapchat is that pictures and messages are usually only available for a short time before they become inaccessible to their recipients. The app has evolved from originally focusing on person-to-person photo sharing to presently featuring users' "Stories" of 24 hours of chronological content, along with "Discover", letting brands show ad-supported short-form content. It also allows users to keep photos in the "my eyes only" which lets them keep their photos in a password-protected space. It has also reportedly incorporated limited use of end-to-end encryption, with plans to broaden its use in the future.

Snapchat was created by Evan Spiegel, Bobby Murphy, and Reggie Brown,[7] former students at Stanford University. It has become known for representing a new, mobile-first direction for social media, and places significant emphasis on users interacting with virtual stickers and augmented reality objects. As of July 2021, Snapchat had 293 million daily active users, a 23% growth over a year.[8] On average more than four billion Snaps are sent each day.[9] Snapchat is popular among the younger generations, particularly those below the age of 16, leading to many privacy concerns for parents.

According to documents and deposition statements, Reggie Brown brought the idea for a disappearing pictures application to Evan Spiegel because Spiegel had prior business experience. Brown and Spiegel then pulled in Bobby Murphy, who had experience coding. The three worked closely together for several months and launched Snapchat as "Picaboo" on the iOS operating system on July 8, 2011.[10][11] Reggie Brown was ousted from the company months after it was launched.[12][13]

The app was relaunched as Snapchat in September 2011, and the team focused on usability and technical aspects, rather than branding efforts.[14] One exception was the decision to keep a mascot designed by Brown, "Ghostface Chillah", named after Ghostface Killah of the hip-hop group Wu-Tang Clan.[14]

On May 8, 2012, Reggie Brown sent an email to Evan Spiegel during their senior year at Stanford, in which he offered to re-negotiate his equitable share regarding ownership of the company. Lawyers for Snapchat responded by insisting that he had never had any creative connection to the product. The attorneys also accused Brown of committing fraud against Spiegel and Murphy by falsely claiming to be a product inventor. On behalf of their clients, the law firm concluded that Reggie Brown had made no contributions of value or worth, and was therefore entitled to a share of nothing.[15][16] In September 2014, Brown settled with Spiegel and Murphy for $157.5 million[17] and was credited as one of the original authors of Snapchat.[7][18][19]

In their first blog post, dated May 9, 2012, CEO Evan Spiegel described the company's mission: "Snapchat isn’t about capturing the traditional Kodak moment. It’s about communicating with the full range of human emotion—not just what appears to be pretty or perfect."[20] He presented Snapchat as the solution to stresses caused by the longevity of personal information on social media, evidenced by "emergency detagging of Facebook photos before job interviews and photoshopping blemishes out of candid shots before they hit the internet.

As of May 2012, 25 Snapchat images were being sent per second[22] and, as of November 2012, users had shared over one billion photos on the Snapchat iOS app, with 20 million photos being shared per day.[22][23] That same month, Spiegel cited problems with user base scalability as the reason why Snapchat was experiencing some difficulties delivering its images, known as "snaps", in real time.[22] Snapchat was released as an Android app on October 29, 2012.[22]

In June 2013, Snapchat version 5.0, dubbed "Banquo", was released for iOS. The updated version introduced several speed and design enhancements, including swipe navigation, double-tap to reply, an improved friend finder, and in-app profiles.[24] The name is a reference to the ghostly hero from Shakespeare's Macbeth, a character in the play who is ultimately seen to be victorious over evil.[25] Also in June 2013, Snapchat introduced Snapkidz for users under 13 years of age. Snapkidz was part of the original Snapchat application and was activated when the user provided a date of birth to verify his/her age. Snapkidz allowed children to take snaps and draw on them, but they could not send snaps to other users and could only save snaps locally on the device being used.[26]

According to Snapchat's published statistics, as of May 2015, the app's users were sending 2 billion videos per day, reaching 6 billion by November.[27] By 2016, Snapchat had hit 10 billion daily video views.[28] In May 2016, Snapchat raised $1.81 billion in equity offering, suggesting strong investor interest in the company.[29] By May 31, 2016, the app had almost 10 million daily active users in the United Kingdom.[30] In February 2017, Snapchat had 160 million daily active users,[31][32] growing to 166 million in May.[33][34]

Investel Capital Corp., a Canadian company, sued Snapchat for infringement on its geofiltering patent in 2016.[35][36] They were seeking "monetary compensation and an order that would prohibit California-based Snapchat from infringing on its patent in the future."

In September 2016, Snapchat Inc. was renamed Snap Inc. to coincide with the introduction of the company's first hardware product, Spectacles—smartglasses with a built-in camera that can record 10 seconds of video at a time.[38] On February 20, 2017, Spectacles became available for purchase online.[39]

Snapchat announced a redesign in November 2017,[40] which proved controversial with many of its followers. CNBC's Ingrid Angulo listed some of the reasons why many disliked the update, citing that sending a snap and re-watching stories was more complicated, stories and incoming snaps were now listed on the same page, and that the Discover page now included featured and sponsored content.[41] A tweet sent by Kylie Jenner in February 2018, which criticized the redesign of the Snapchat app,[42] reportedly caused Snap Inc. to lose more than $1.3 billion in market value.[43][44] Over 1.2 million people signed a Change.org petition asking the company to remove the new app update.[45]

In December 2019, App Annie announced Snapchat to be the 5th most downloaded mobile app of the decade. The data includes figures for iOS downloads starting from 2010 and Android downloads starting from 2012.[46] Snapchat acquired AI Factory, a computer vision startup, in January 2020 to give a boost to its video capabilities.[47]

In November 2020, Snapchat announced it would pay a total of $1 million a day to users who post viral videos. The company has not stated the criteria for a video to be considered viral or how many people the payout would be split between. The promotion, called Snapchat Spotlight, is intended to run until the end of the year, although the company indicated it will continue if it's successful.

Abstract:

The high-fidelity sensors and ubiquitous internet connectivity offered by mobile devices have facilitated an explosion in mobile device apps that rely on multimedia features. However, these sensors can also be used in ways that may violate user's expectations and personal privacy. For example, apps have been caught taking pictures without the user's knowledge and passively listened for inaudible, ultrasonic audio beacons. The developers of mobile device operating systems recognize that sensor data is sensitive, but unfortunately existing permission models only mitigate some of the privacy concerns surrounding multimedia data. In this work, we present the first large-scale empirical study of media permissions and leaks from Android apps, covering 17,260 apps from Google Play, App China, Mi.com, and Anzhi. We empirically study the behavior these apps using a combination of static and dynamic analysis techniques. Our study reveals several alarming privacy risks in the Android app ecosystem, including apps that over-provision their media permissions and apps that share image and video data with other parties in unexpected ways, without user knowledge or consent. We also identify a previously unreported privacy risk that arises from third party libraries that record and upload screenshots and videos of the screen without informing the user. This can occur without needing any permissions from the user.
