Its public offering in December was the biggest since 1956, when the Ford Motor Company had gone public. However, Apple would soon face competition from the computer industry’s leading player, International Business Machines Corporation. IBM had waited for the personal computer market to grow before introducing its own line of personal computers, the IBM PC, in 1981. IBM broke with its tradition of using only proprietary hardware components and software and built a machine from readily available components, including the Intel microprocessor, and used DOS (disk operating system) from the Microsoft Corporation. Because other manufacturers could use the same hardware components that IBM used, as well as license DOS from Microsoft, new software developers could count on a wide IBM PC-compatible market for their software. Soon the new system had its own killer app: the Lotus 1-2-3 spreadsheet, which won an instant constituency in the business community-a market that the Apple II had failed to penetrate. Apple had its own plan to regain leadership: a sophisticated new generation of computers that would be dramatically easier to use. In 1979 Jobs had led a team of engineers to see the innovations created at the Xerox Corporation’s Palo Alto (California) Research Center (PARC). There they were shown the first functional graphical user interface (GUI), featuring on-screen windows, a pointing device known as a mouse, and the use of icons, or pictures, to replace the awkward protocols required by all other computers.
However, as the Morris worm and Mydoom showed, even these "payload-free" worms can cause major disruption by increasing network traffic and other unintended effects. The actual term "worm" was first used in John Brunner's 1975 novel, The Shockwave Rider. In the novel, Nichlas Haflinger designs and sets off a data-gathering worm in an act of revenge against the powerful men who run a national electronic information web that induces mass conformity. The second ever computer worm was devised to be an anti-virus software. On November 2, 1988, Robert Tappan Morris, a Cornell University computer science graduate student, unleashed what became known as the Morris worm, disrupting many computers then on the Internet, guessed at the time to be one tenth of all those connected. During the Morris appeal process, the U.S. Morris himself became the first person tried and convicted under the 1986 Computer Fraud and Abuse Act. Computer viruses generally require a host program. The virus writes its own code into the host program.
A comprehensive step-by-step tutorial on how to prepare and run the PyTorch DeepLabV3 image segmentation model on iOS. List of recipes for performance optimizations for using PyTorch on Mobile. Learn how to fuse a list of PyTorch modules into a single module to reduce the model size before quantization. Learn how to reduce the model size and make it run faster without losing much on accuracy. Learn how to convert the model to TorchScipt and (optional) optimize it for mobile apps. Learn how to add the model in an iOS project and use PyTorch pod for iOS. To track the latest updates for iOS, you can build the PyTorch iOS libraries from the source code. Make sure you have cmake and Python installed correctly on your local machine. Open terminal and navigate to the PyTorch root directory. Open terminal and navigate to the PyTorch root directory. In the build settings, search for other linker flags.
The systems are sufficiently similar that a significant fraction of the compiled software produced for one machine will run on the other. Software running via the built-in Basic interpreters also has a high level of compatibility, but only after they are re-tokenized, which can be achieved fairly easily by transferring via cassette tape with appropriate options. It is possible to permanently convert a Color Computer into a Dragon by swapping the original Color Computer ROM and rewiring the keyboard cable. The Dragon has additional circuitry to make the MC6847 VDG compatible with European 625-line television standards, rather than the US 525-line NTSC standard, and a Centronics parallel printer port not present on the TRS-80. Some models were manufactured with NTSC video for the US and Canadian markets. Aside from the amount of RAM, the Dragon 64 also has a functional RS-232 serial port which was not included on the Dragon 32. A minor difference between the two Dragon models is the outer case colour; the Dragon 32 is beige and the Dragon 64 is light grey. Besides the case, branding and the Dragon 64's serial port, the two machines look the same. The Dragon 32 is upgradable to Dragon 64. In some cases, buyers of the Dragon 32 found that they actually received a Dragon 64 unit. The review described it as a redesigned, less-expensive Color Computer with 32K RAM and better keyboard.
