The ActionScript programming language allows the development of interactive animations, video games, web applications, desktop applications, and mobile applications. Programmers can implement Flash software using an IDE such as Adobe Animate, Adobe Flash Builder, Adobe Director, FlashDevelop, and Powerflasher FDT. Adobe AIR enables full-featured desktop and mobile applications to be developed with Flash and published for Windows, macOS, Android, iOS, Xbox One, PlayStation 4, Wii U, and Nintendo Switch.
Developers could create rich internet applications and browser plugin-based applets in ActionScript 3.0 programming language with IDEs, including Adobe Flash Builder, FlashDevelop and Powerflasher FDT. Flex applications were typically built using Flex frameworks such as PureMVC.[21]
The Flash 4 Linux project was an initiative to develop an open source Linux application as an alternative to Adobe Animate. Development plans included authoring capacity for 2D animation, and tweening, as well as outputting SWF file formats. F4L evolved into an editor that was capable of authoring 2D animation and publishing of SWF files. Flash 4 Linux was renamed UIRA. UIRA intended to combine the resources and knowledge of the F4L project and the Qflash project, both of which were Open Source applications that aimed to provide an alternative to the proprietary Adobe Flash.
In the same year that Shumway was abandoned, work began on Ruffle, a flash emulator written in Rust. It also runs in web browsers, by compiling down to WebAssembly and using HTML5 Canvas.[137] In 2020, the Internet Archive added support for emulating SWF by adding Ruffle to its emulation scheme.[138] As of March 2023, Ruffle states that it supports 95% of the AS1/2 language and 73% of the AS1/2 APIs, but does not correctly run most AS3 (AVM2) applications.[139]
Like the HTTP cookie, a flash cookie (also known as a "Local Shared Object") can be used to save application data. Flash cookies are not shared across domains. An August 2009 study by the Ashkan Soltani and a team of researchers at UC Berkeley found that 50% of websites using Flash were also employing flash cookies, yet privacy policies rarely disclosed them, and user controls for privacy preferences were lacking.[206] Most browsers' cache and history suppress or delete functions did not affect Flash Player's writing Local Shared Objects to its own cache in version 10.2 and earlier, at which point the user community was much less aware of the existence and function of Flash cookies than HTTP cookies.[207] Thus, users with those versions, having deleted HTTP cookies and purged browser history files and caches, may believe that they have purged all tracking data from their computers when in fact Flash browsing history remains. Adobe's own Flash Website Storage Settings panel, a submenu of Adobe's Flash Settings Manager web application, and other editors and toolkits can manage settings for and delete Flash Local Shared Objects.[208]
The flash provides a way to pass temporary primitive-types (String, Array, Hash) between actions. Anything you place in the flash will be exposed to the very next action and then cleared out. This is a great way of doing notices and alerts, such as a create action that sets flash[:notice] = "Post successfully created" before redirecting to a display action that can then expose the flash to its template. Actually, that exposure is automatically done.
This example places a string in the flash. And of course, you can put as many as you like at a time too. If you want to pass non-primitive types, you will have to handle that in your application. Example: To show messages with links, you will have to use sanitize helper.
Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks and rewrites data at the byte level. Flash memory is widely used for storage and data transfer in consumer devices, enterprise systems and industrial applications. Flash memory retains data for an extended period regardless of whether a flash-equipped device is powered on or off.
Flash memory is used in enterprise data center server, storage and networking technology as well as in a wide range of consumer devices, including USB flash drives -- also known as memory sticks -- SD cards, mobile phones, digital cameras, tablet computers, and PC cards in notebook computers and embedded controllers.
There are two types of flash memory: NAND and NOR. NAND flash-based solid-state drives (SSDs) are often used to accelerate the performance of I/O-intensive applications. NOR flash memory is often used to hold control code, such as the BIOS in a PC.
Dr. Fujio Masuoka is credited with inventing flash memory when he worked for Toshiba in the 1980s. Masuoka's colleague, Shoji Ariizumi, reportedly coined the term flash because the process of erasing all the data from a semiconductor chip reminded him of the flash of a camera.
Flash memory evolved from erasable programmable read-only memory (EPROM) to electrically erasable programmable read-only memory (EEPROM). Flash is technically a variant of EEPROM, but the industry reserves the term EEPROM for byte-level erasable memory and applies the term flash memory to larger block-level erasable memory.
Structure. Flash memory architecture includes a memory array stacked with a multitude of flash cells. A basic flash memory cell consists of a storage transistor with a control gate and a floating gate, which is insulated from the rest of the transistor by a thin dielectric material or oxide layer. The floating gate stores the electrical charge and controls the flow of the electrical current.
Electrical isolation and persistent storage. Electrons are trapped in the floating gate regardless of whether a device containing the flash memory cell is receiving power because of electrical isolation created by the oxide layer. This characteristic enables flash memory to provide persistent storage.
NOR and NAND flash memory differ in architecture and design characteristics. NOR flash uses no shared components and can connect individual memory cells in parallel, enabling random access to data. A NAND flash cell is more compact and has fewer bit lines, stringing together floating gate transistors to increase storage density.
NOR flash is fast on data reads, but it's typically slower than NAND on erases and writes. NOR flash programs data at the byte level. NAND flash programs data in pages, which are larger than bytes, but smaller than blocks. For instance, a page might be 4 kilobytes (KB), while a block might be 128 KB to 256 KB or megabytes in size. NAND flash consumes less power than NOR flash for write-intensive applications.
NOR flash is more expensive to produce than NAND flash and tends to be used primarily in consumer and embedded devices for boot purposes and read-only applications for code storage. NAND flash is more suitable for data storage in consumer devices as well as enterprise server and storage systems due to its lower cost per bit to store data, greater density, and higher programming and erase speeds.
An additional subcategory is a hybrid hard drive that combines a conventional HDD with a NAND flash module. A hybrid hard drive is generally viewed to bridge the divide between rotating media and flash memory.
The advent of flash memory fueled the rise of all-flash arrays. These systems, which contain only SSDs, offer advantages in performance and potentially reduced operational costs compared to all disk-based storage arrays. The chief difference, aside from the media, is in the underlying physical architecture used to write data to a storage device.
HDD-based arrays have an actuator arm that lets data be written to a specific block on a specific sector on the disk. All-flash storage systems don't require moving parts to write data. The writes are made directly to the flash memory and custom software handles data management.
A hybrid flash array blends disk and SSDs. Hybrid arrays use SSDs as a cache to speed access to frequently requested hot data, which subsequently is rewritten to back-end disk. Many enterprises commonly archive data from disk as it ages by replicating it to an external magnetic tape library.
In addition to flash memory arrays, the ability to insert SSDs in x86-based servers has increased the technology's popularity. This arrangement is known as server-side flash memory, and it lets companies sidestep the vendor lock-in associated with purchasing expensive and integrated flash storage arrays.
The drawback of placing flash in a server is that users must build the hardware system internally, including the purchase and installation of a storage management software stack from a third-party vendor.
The main disadvantages of flash memory are the wear-out mechanism and cell-to-cell interference as the dies get smaller. Bits can fail with excessively high numbers of program/erase cycles, which eventually break down the oxide layer that traps electrons. The deterioration can distort the manufacturer-set threshold value at which a charge is determined to be a zero or a one. Electrons could escape and get stuck in the oxide insulation layer, leading to errors and bit rot.
Anecdotal evidence suggests NAND flash drives aren't wearing out to the degree once feared. Flash drive manufacturers have improved endurance and reliability through error correction code algorithms, wear leveling and other technologies.
The two main types of NOR flash memory are parallel and serial, also known as serial peripheral interface. NOR flash was originally available only with a parallel interface. Parallel NOR offers high performance, security and additional features. Its primary uses include industrial, automotive, networking and telecom systems and equipment.
Serial NOR flash has a lower pin count and smaller packaging, making it less expensive than parallel NOR. Use cases for serial NOR include personal and ultra-thin computers, servers, HDDs, printers, digital cameras, modems and routers.
