He wanted these to filter out to the existing Unix user base, but the company's lawyers felt that this would constitute a form of support and balked at their release.
Nevertheless, those bug fixes soon became widely distributed through unofficial channels. For instance, Lou Katz, the founding president of Usenix, received a phone call one day telling him that if he went down to a certain spot on Mountain Avenue where Bell Labs was located at 2 p.
Sure enough, Katz found a magnetic tape with the bug fixes, which were rapidly in the hands of countless users. By the end of the s, Unix, which had started a decade earlier as a reaction against the loss of a comfortable programming environment, was growing like a weed throughout academia and the IT industry. Unix would flower in the early s before reaching the height of its popularity in the early s.
For many reasons, Unix has since given way to other commercial and noncommercial systems. But its legacy, that of an elegant, well-designed, comfortable environment for software development, lives on. In recognition of their accomplishment, Thompson and Ritchie were given the Japan Prize earlier this year, adding to a collection of honors that includes the United States' National Medal of Technology and Innovation and the Association of Computing Machinery's Turing Award.
Many other, often very personal, tributes to Ritchie and his enormous influence on computing were widely shared after his death this past October. Unix is indeed one of the most influential operating systems ever invented. Its direct descendants now number in the hundreds. On the other side are various Unix-like operating systems derived from the version of Unix developed at the University of California, Berkeley, including the one Apple uses today on its computers, OS X.
Had this operating system been available at the time, Linus Torvalds says he probably wouldn't have created Linux , an open-source Unix-like operating system he developed from scratch for PCs in the early s. Linux has carried the Unix baton forward into the 21st century, powering a wide range of digital gadgets including wireless routers, televisions, desktop PCs, and Android smartphones. It even runs some supercomputers. By , no fewer than five major lawsuits had been filed. As a programmer and Unix historian, I can't help but find all this legal sparring a bit sad.
From the very start, the authors and users of Unix worked as best they could to build and share, even if that meant defying authority. That outpouring of selflessness stands in sharp contrast to the greed that has driven subsequent legal battles over the ownership of Unix.
The world of computer hardware and software moves forward startlingly fast. For IT professionals, the rapid pace of change is typically a wonderful thing. But it makes us susceptible to the loss of our own history, including important lessons from the past. That effort morphed into the Unix Heritage Society. Our goal is not only to save the history of Unix but also to collect and curate these old systems and, where possible, bring them back to life.
With help from many talented members of this society, I was able to restore much of the old Unix software to working order, including Ritchie's first C compiler from and the first Unix system to be written in C, dating from One holy grail that eluded us for a long time was the first edition of Unix in any form, electronic or otherwise. This was an amazing find—like discovering an old Ford Model T collecting dust in a corner of a barn. But we didn't just want to admire the chrome work from afar.
We wanted to see the thing run again. In , Tim Newsham, an independent programmer in Hawaii, and I assembled a team of like-minded Unix enthusiasts and set out to bring this ancient system back from the dead.
We sent out messages announcing our success to all those we thought would be interested. Warren Toomey teaches at Bond University, in Australia. He was bitten by the Unix bug in while still in high school, when he spent two weeks at the University of Wollongong learning about computers.
Craig S. China has taken another step toward semiconductor independence with Alibaba announcing the design of a 5-nanometer technology server chip that is based on Arm Ltd. But, impressive as that feat is, an even more significant chip design development by the Chinese tech giant may be making available the source code to a RISC-V CPU core its own engineers designed.
This means other companies can use it in their own processor designs—and escape architecture license fees.
The company made both announcements at its annual cloud convention in its home city of Hangzhou last month. The Chinese government is funding a lot of startups that are designing a variety of chips. The number of newly registered Chinese chip-related companies more than tripled in the first five months of from the same period a year ago. And the biggest Chinese technology companies like Alibaba, Baidu, and Huawei are developing their own chips rather than banking on those from Intel, Nvidia, and other United States-based companies.
China is intent on developing semiconductor independence, both in design and manufacture of state-of-the-art chips. The urgency for doing so has been helped along by U. The sanctions extend to any Huawei suppliers that use U. The United States, alarmed at China's campaign to bring Taiwan under its control, has also begun an ambitious program to 'reshore' its semiconductor manufacturing after allowing much of it to migrate to Taiwan.
Around 80 percent of the world's semiconductor production capacity is in Asia, and nearly all the most advanced logic chip production is in Taiwan.
No Chinese semiconductor foundry has yet achieved the 5-nanometer processing needed to make Alibaba's new ARM-based chip, so it is still beholden to Taiwan for manufacturing. But the implications of Alibaba's general choice of Arm and RISC-V instruction set architectures is perhaps more consequential for the long term.
An instruction set architecture, or ISA, is the language in which software talks to hardware, and thus determines the kind of software that can run on a particular chip. Most servers use CPUs based on Intel's x86 instruction set architecture. But UK-based Arm, which licenses its instruction set architecture to chip designers, has been gaining a foothold in this market.
RISC-V, which refers to the fifth generation of an open-source reduced instruction set computer architecture created by U. This past June, China hosted the fourth annual RISC-V summit, bringing together industry, academia, and government to talk about the future of the architecture. In the wake of the U. Unable to buy Intel chips because of the sanctions, Huawei most recently sold its x86 server unit to a company owned by China's Henan province.
From the beginning, the company indicated that it intended to open the CPU's source code—the hardware description language that describes the structure and behavior of the CPU core's electronic circuits.
It has now done so… with little fanfare. Its Yitian server system on a chip SoC , manufactured by Taiwan's TSMC, will have a total of Arm-based cores, with 60 billion integrated transistors and a top clock speed of 3. Alibaba said it is the first server processor compatible with the latest Armv9 architecture. Alibaba said the SoC achieved a score of in SPECint a standard benchmark for measuring CPU integer processing power , surpassing that of the current state-of-the-art Arm server processor based on Armv8 by 20 percent in performance and 50 percent in energy efficiency.
The company also announced the development of proprietary servers, under the brand name Panjiu , developed for the next-generation of cloud-native infrastructure.
By separating computing from storage, the servers are optimized for both general-purpose and specialized AI computing, as well as high-performance storage. The company vowed to provide more services and support for RISC-V development tools, software development kits, and customized cores in the future. It is a stable, multi-user, multi-tasking system for servers, desktops and laptops. Contrary to popular belief, Linux is not just for engineers and programmers. But eventually, Linux took the lead and become the preferred choice of operating system for the supercomputers.
UNIX, multiuser computer operating system. UNIX is widely used for Internet servers, workstations, and mainframe computers. The tools and applications that offer additional functionality to the operating system. As with many operating systems for servers, the Unix-like systems can host multiple users and programs simultaneously. Unix is popular with programmers for a variety of reasons. Unix systems have a hierarchical file system that allows relative and absolute file path naming.
