Who owns ms dos

Kildall died in , but the rumor that Microsoft copied his creation persists to this day. Recently, a man named Bob Zeidman decided to settle the matter once and for all. He examined the code in question using a set of tools he developed for detecting copyright violations in software, and last month he published his findings in the pages of IEEE Spectrum. But it turns out Zeidman has a history with Microsoft. Rebecca Mercuri, another forensic computing researcher, pointed out in the comments of the IEEE Spectrum article that Zeidman's resume says he's an expert witness in the ongoing battle between Microsoft and Motorola over the Android mobile operating system.

This tie was not disclosed in the article. He and his group delivered the initial version of 1. Then the Boca Raton deluge came. It really drove me nuts.

I felt like a puppet on an IBM string. Paterson spent the last weeks of that month planning 2. Then, on April 1, he suddenly quit Microsoft. Not a man to burn his bridges, Paterson left Microsoft on good terms and returned to Seattle Computer to work, at first, on Seattle's floppy disk controller.

Wrong-Way Paterson. Seattle Computer was doing quite well. Paterson had owned 10 percent of the company since , and had been an officer and member of the board. Achieving such a position at Microsoft was unlikely. At Seattle, I'm director of engineering. That's really motivating. It was the basis for my moving back. I was a little irritated with Microsoft, mainly having to work with IBM.

Microsoft recognizes talent. If somebody complains, they try to move them around. At present, he and Seattle Computer are "catching up. We want to catch up with those four function guys. We're also working on a new enclosure for the Gazelle. I don't think I will, though, not at Seattle Computer. I don't have the time. I can picture all kinds of neat things--combined packages.

Memory's cheap these days and it should be possible to have a spreadsheet, word processor, database, and more at fingertip control in one package. It'll go through a software jump; it hasn't caught up with the Z yet. Speed Racer. When far from the world of programming and corporate politics, Paterson is something of a race-car nut.

He codrives a Mazda RX-2 in pro rallies. I have an RX-7 and, yeah, I'm kinda into cars. Paterson is still looking for that elusive something.

Independently minded, he seeks complete freedom. He doesn't want to work for someone else all his life. More properly put, he doesn't want always to be doing someone else's work.

Some year Paterson would like to start his own company. When his Seattle Computer stock is worth enough, he just may sell it and go off on his own. Rod Brock said to me, 'Tim, in a few years you'll go. Small companies that make it either become big or become part of a big company. For the moment, Paterson is just another brilliant programmer.

He's happy, but a little sad sometimes. The acronym DOS was not new even then. It had originally been used by IBM in the s in the name of an operating system i. IBM subjected the operating system to an extensive quality-assurance program, reportedly found well over bugs, and decided to rewrite several programs. And in what was to become another extremely fortuitous move, Bill Gates persuaded IBM to let his company retain marketing rights for the operating system separately from the IBM PC project.

The two versions were initially nearly identical, but they eventually diverged. Later they added several other languages.

As PC became the most popular personal computer, revenue from its sales fueled Microsoft's phenomenal growth, and MS-DOS was the key to company's rapid emergence as the dominant firm in the software industry. This product continued to be the largest single contributor to Microsoft's income well after it had become more famous for Windows.

The original version of DOS version 1. For several years they produced a new version each year and each version contained significant enhancements:. And by DOS became a de-facto standard. Additions and improvements in subsequent versions included support for multiple hard disk partitions, for disk compression and for larger partitions as well as an improved disk checking program, improved memory management, a disk defragmenter and an improved text editor.

In spite of its very small size and relative simplicity, it is one of the most successful operating systems that has been developed. Paradoxically this simple system was more popular then all versions of Unix combined despite the fact that Unix is much more complex and richer OS or may be because of that. DOS is a text-based Bit single-user, single-tasking operating system. Later versions of MS-DOS brought some changes in memory handling and peripheral support, but because of its architecture, DOS was unable to make use of the capabilities of and later Intel chips.

Though limited to a single program mode, DOS is still preferred by many programmers mainly developers of games , because the application has full control over all resources in the PC. While two-button mouse was widely available on PCs approximately from , DOS programs widely used "letter accelerators" for menus.

DOS games became the most successful software industry and many of DOS games became instant classics. Many site on Internet still make them available for download. As Wikipedia stated:. The first version was released in May, Compaq's variant was the first to introduce the system for supporting hard disk partitions of over 32MB which was later to become the standard used in MS-DOS 4. As a result, DRI was approached by a number of PC manufacturers who were interested in a third-party DOS, and this prompted several updates to the system.

First, on Intel or better microprocessors with 1MB or more RAM, the DR-DOS kernel and structures such as disk buffers could be located in the High Memory Area , the first 64KB of extended memory which were accessible in real mode due to an incomplete compatibility of the with earlier processors. For more information on this, see the article on the Upper Memory Area.

As such, on a system, it could offer vastly more free conventional memory than any other DOS. Once drivers for a mouse, multimedia hardware and a network stack were loaded, an MS-DOS machine typically might only have to KB of free conventional memory — too little to run most lates software.

DR-DOS 5, with a small amount of manual tweaking, could load all this and still keep all of its conventional memory free — allowing for some necessary DOS data structures, as much as KB out of the KB. So much, in fact, that some programs would fail to load as they started "impossibly" low in memory — inside the first 64KB. Given the constraints of the time, this was an incredibly powerful technology which made life much easier for PC technicians of the day, and this propelled DR-DOS 5.

Faced with substantial competition in the DOS arena, Microsoft responded strongly. It included matches of the DR's enhancements in memory management, but did not offer all of the improvements to the syntax of DOS commands that DR did. This bundled in SuperStor on-the-fly disk compression, to maximise the space available on the tiny hard disks of the time - 40MB was still not an atypical size, which with the growth of larger applications and especially Microsoft Windows was frequently not enough space.

DR-DOS 6. On based systems, DOS applications could be suspended to the background to allow others to run. However, DR's multitasking system was seen as technically inferior to third-party offerings such as DESQview , which could multitask applications which performed direct hardware access and graphical applications and even present them in scalable on-screen windows.

Though far from being a true "multitasking" operating system, TaskMax nonetheless represented an important "tick on the box" - a feature on the list of specifications. In one example, they inserted code into the beta version of Windows 3. IBM was the second company that tried to fight MS-DOS dominance, but it entered in the war too late when major battles were already lost.

But at version 6 those two OSes diverged. PC-DOS 7 was substantially more reliable and easier to configure than any of its competitors. Versions 7 and natively support a XDF floppy format The final major version was probably DOS 7. It featured close integration with that operating system, including support for long filenames and removal of some command line utilities, that were preserved and can installed separately from Windows 95 CDROM.

It was revised in with version 7. The introduction of the Apple Macintosh in brought about a surge of interest in GUIs graphical user interfaces , and it soon became apparent that they are the future of personal computer interface. Although many MS-DOS programs created their own sometimes very sophisticated command line based GUIs, this approach required duplication of programming effort, and the lack of a consistent GUI API made it more difficult for users to learn new programs and for developers to develop them.

It took Microsoft several years to provide high quality GUI of its own, but it finally succeeded with the introduction of Windows 95 in which has taken market by storm making DOS obsolete. Still even previous version of Windows starting with Windows 3. Protected mode and real mode are the two modes of operation supported by the Intel x86 architecture. The former enables bit memory addressing, thereby permitting use of the extended memory that cannot be easily accessed from real mode. This makes it possible to assign separate memory areas to the operating system kernel and to each process i.

MS-DOS has a relatively small number of commands, and an even smaller number of commonly used ones. They can be glued together by very primitive shell called Batch file. Moreover, these commands are generally inflexible because, in contrast to Unix-like operating systems, they are designed to accommodate few options or arguments i.

Some of the most common commands are as follows corresponding commands on Unix-like operating systems are shown in parenthesis :. Primitivism of DOS shell simulated creation of various file managers see The History of Development of Norton Commander with additional shell capabilities as well as alternative shells, the most successful of which was 4DOS.

However, there are some very fundamental differences, including:. Because Linux was originally developed on PCs and at a time when MS-DOS was the dominant PC operating system, a variety of tools were developed to help developers and users bridge the gap between the two operating systems. Emulators are also available for running DOS on other versions of Unix, even on non-x86 processors.

Included in mtools are more than 20 commands, all of which are identical to their MS-DOS counterparts except that the letter m is added to the start of each of their names. Although it is widely believed that MS-DOS is an antiquated dead operating system with few features and capabilities, this is far from correct. In fact, although not generally publicized, MS-DOS is still used today by numerous businesses and individuals around the world.

It survived for so long because is is robust, relatively simple and continue to get the job done with a minimum of maintenance. DOS is one of the most secure operating system in existence. Application doe DOS do not "dial home" and do not automatic updates which are essentially a backdoor. At the same time the quality of application is extremely high. DOS is still one of the best way to run recovery programs, low-level disk utilities, the flashing of the system BIOS and diagnostics.

In it used in several popular programs with Norton Ghost probably the most popular. In many cases, it was not DOS itself that was the limiting factor in system performance; rather, it was the hardware, including small memories, slow CPUs and slow video cards. The capabilities of DOS have, in fact, continued to increase for several year after Microsoft Windows 95 became widespread.

This is a result of continuing advances in the hardware support and the introduction of new or improved utilities and applications. PC DOS 7. Its latest publicly available build is from December DOS will be around for many years into the future not only because of the continued existence of legacy applications and extremely rich high-quality tool chain that even today is in some segments is richer then Linux tool chain but also because of security concerns that are now pretty widespread in Windows environment.

The main area of growth will most likely be simple embedded applications, for which DOS is attractive because of its extremely small size, very reliable operation, well developed toolset including high quality compilers from C and zero cost in the case of DrDos and FreeDOS. One game that might trigger a few memories is the action-adventure horror game Alone in the Dark , published by Infogrames. In the game, you can play private investigator Edward Carnby or family member Emily Hartwood, who's investigating the suspicious death of Jeremy Hartwood in his Louisiana mansion called Derceto, which is now supposedly haunted.

Fighting against rats, zombies and giant worms, you have to solve a number of puzzles to escape. Players can choose from three different characters -- Mr. Blobby, Mrs. Blobby and Baby Blobby. The goal of the game is to color in the computer screen by walking over it. Levels include climbing ladders, avoiding spikes and bouncing on springs. FreeDOS turns 25 years old: An origin story The operating system's history is a great example of the open source software model: developers working together to create something.

That's a major milestone for any open source software project, and I'm proud of the work that we've done on it over the past quarter century. I'm also proud of how we built FreeDOS because it is a great example of how the open source software model works.

MS-DOS provided a flexible command line, which I quite liked and that came in handy to manipulate my files. Over the years, I learned how to write my own utilities in C to expand its command-line capabilities even further. But I liked DOS. I figured that if we wanted to keep DOS, we would need to write our own. And that's how FreeDOS was born.

On June 29, , I made a small announcement about my idea to the comp. The general support for this at the time was strong, and many people agreed with the statement, "start writing! I have written up a "manifest" describing the goals of such a project and an outline of the work, as well as a "task list" that shows exactly what needs to be written.

I'll post those here, and let discussion follow. I started working on it right away. I contributed over a dozen FreeDOS utilities. By sharing my utilities, I gave other developers a starting point. Other developers who saw FreeDOS taking shape contacted me and wanted to help. Others contributed utilities that replicated or expanded the DOS command line.

We released our first alpha version as soon as possible. Less than three months after announcing FreeDOS, we had an Alpha 1 distribution that collected our utilities.

New developers joined the project, and we welcomed them. You may be familiar with other milestones. We crept our way towards the 1. MS-DOS stopped being a moving target long ago, so we didn't need to update as frequently after the 1. FreeDOS supports networking and even provides a simple graphical web browser Dillo. And we have tons of new utilities, including many that will make Linux users feel at home. FreeDOS got where it is because developers worked together to create something.

In the spirit of open source software, we contributed to each other's work by fixing bugs and adding new features. We treated our users as co-developers; we always found ways to include people, whether they were writing code or writing documentation. And we made decisions through consensus based on merit. If that sounds familiar, it's because those are the core values of open source software: transparency, collaboration, release early and often, meritocracy, and community.

That's the open source way! Microsoft co-founder Paul Allen died today from complications with non-Hodgkin's lymphoma. He was Allen said earlier this month that he was being treated for the disease. Allen was a childhood friend of Bill Gates, and together, the two started Microsoft in He left the company in while being treated for Hodgkin's lymphoma and remained a board member with the company through He was first treated for non-Hodgkin's lymphoma in , before seeing it go into remission.

In a statement given to ABC News , Gates said he was "heartbroken by the passing of one of my oldest and dearest friends. From our early days together at Lakeside School, through our partnership in the creation of Microsoft, to some of our joint philanthropic projects over the years, Paul was a true partner and dear friend.

Personal computing would not have existed without him. But Paul wasn't content with starting one company. He channelled his intellect and compassion into a second act focused on improving people's lives and strengthening communities in Seattle and around the world.

He was fond of saying, "If it has the potential to do good, then we should do it. Paul loved life and those around him, and we all cherished him in return. He deserved much more time, but his contributions to the world of technology and philanthropy will live on for generations to come.

I will miss him tremendously. Paul Allen's contributions to our company, our industry, and to our community are indispensable. As co-founder of Microsoft, in his own quiet and persistent way, he created magical products, experiences and institutions, and in doing so, he changed the world. I have learned so much from him -- his inquisitiveness, curiosity, and push for high standards is something that will continue to inspire me and all of us as Microsoft.

Our hearts are with Paul's family and loved ones. Rest in peace. In a memoir published in , Allen says that he was responsible for naming Microsoft and creating the two-button mouse. The book also portrayed Allen as going under-credited for his work at Microsoft, and Gates as having taken more ownership of the company than he deserved.

It created some drama when it arrived, but the two men ultimately appeared to remain friends, posing for a photo together two years later. After leaving Microsoft, Allen became an investor through his company Vulcan, buying into a diverse set of companies and markets. Vulcan's current portfolio ranges from the Museum of Pop Culture in Seattle, to a group focused on using machine learning for climate preservation, to Stratolaunch, which is creating a spaceplane.

Allen's investments and donations made him a major name in Seattle, where much of his work was focused. NFL Commissioner Roger Goodell said Allen "worked tirelessly" to "identify new ways to make the game safer and protect our players from unnecessary risk. He also launched a number of philanthropic efforts, which were later combined under the name Paul G.

Allen Philanthropies. My brother was a remarkable individual on every level. While most knew Paul Allen as a technologist and philanthropist, for us he was a much loved brother and uncle, and an exceptional friend. Paul's family and friends were blessed to experience his wit, warmth, his generosity and deep concern.

For all the demands on his schedule, there was always time for family and friends. At this time of loss and grief for us — and so many others — we are profoundly grateful for the care and concern he demonstrated every day. One recent project, the Allen Brain Observatory , provides an open-access "catalogue of activity in the mouse's brain," Saskia de Vries, senior scientist on the project, said in a video. That kind of data is key to piecing together how the brain processes information.

In an interview with Matthew Herper at Forbes , Allen called the brain "hideously complex" -- much more so than a computer. Allen Frontiers Group in , which funds cutting-edge research. Even back in , when Allen spoke with Herper at Forbes , he talked about plans for his financial legacy after his death -- and he said that a large part of it would be "allocated to this kind of work for the future.

Paul's vision and insight have been an inspiration to me and to many others both here at the Institute that bears his name, and in the myriad of other areas that made up the fantastic universe of his interests. He will be sorely missed. We honor his legacy today, and every day into the long future of the Allen Institute, by carrying out our mission of tackling the hard problems in bioscience and making a significant difference in our respective fields.

According to Quincy Jones, Allen was also an excellent guitar player. Man what a shock! He liked to swing by office on a regular basis as we were just a few blocks from Dicks hamburgers on Mercer St his favorite.

He was really an engineer's engineer. We'd give him a status report on how things were going and within a few minutes he was up at the white board spitballing technical solutions to ASIC or network problems. I especially remember him coming by the day he bought the Seahawks. Paul was a big physical presence 6'2" lbs in those days , but he kept going on about how after meeting the Seahawks players, he never felt so physically small in his life. Ignore the internet trolls. Paul was a good guy.

He was a humble, modest, down-to-earth guy. There was always a pick-up basketball game on his court on Thursday nights. Jam session over at his place were legendary I never got to play with him, but every musician that I know that played with him was impressed with his guitar playing.

He left a huge legacy in the pacific northwest. We'll miss you Paul! The book Paul Allen wrote avoids a full report, but gives the impression that Bill Gates was so angry, Paul Allen left the company because interacting with Bill Gates was bad for his health. Quotes from the book, Idea Man [amazon. His reply: "It was neat that they got along well enough that the company didn't explode in the first year or two.

When Bill pushed on licensing terms or bad-mouthed the flaky Signetics cards, Ed thought he was insubordinate. You could hear them yelling throughout the plant, and it was quite a spectacle-the burly ex-military officer standing toe to toe with the owlish prodigy about half his weight, neither giving an inch.

At product review meetings, his scathing critiques became a perverse badge of honor. One game was to count how many times Bill confronted a given manager; whoever got tagged for the most "stupidest things " won the contest. He used to have the nickname "Doctor NetVorkian" because many of the things he invested in promptly tanked in one way or another after his investment. He had a lot of bad luck with his investments.

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. Consultant Gwennap suggests that Alibaba's Arm and RISC-V efforts are experiments more than commercial endeavors, noting that Alibaba is still using x86 Intel chips for the vast majority of its internal use.

Alibaba's new Arm-based server chip will be used in Alibaba datacenters to provide cloud services to customers.. The company will continue to offer Intel-based services, so it's up to customers to choose Arm over xbased chips. When Amazon did something similar a few years ago, there was little uptake for the Arm-based chips. But true semiconductor independence will require China to develop its own extreme ultraviolet lithography machines , required to etch microscopic circuits on silicon.

SMIC , China's main chip foundry, can't provide anything smaller than 14 nm. SMIC claims to have mastered the 3nm chip process in the lab and is trying to buy the EUV lithography machines necessary for production from ASML, the Dutch company that currently has a monopoly on the critical equipment. But the United States is intent on blocking the sale. But getting that technology out of the lab and into a machine remains many years away. Japanese startup working towards autonomous robots that can do useful work inside and outside the space station.

Late last year, Japanese robotics startup GITAI sent their S1 robotic arm up to the International Space Station as part of a commercial airlock extension module to test out some useful space-based autonomy. Everything moves pretty slowly on the ISS, so it wasn't until last month that NASA astronauts installed the S1 arm and GITAI was able to put the system through its paces —or rather, sit in comfy chairs on Earth and watch the arm do most of its tasks by itself, because that's the dream, right?

So what's next for commercial autonomous robotics in space? One of the advantages of working in space is that it's a highly structured environment. Microgravity can be somewhat unpredictable, but you have a very good idea of the characteristics of objects and even of lighting because everything that's up there is excessively well defined.

So, stuff like using a two-finger gripper for relatively high precision tasks is totally possible, because the variation that the system has to deal with is low. Of course, things can always go wrong, so GITAI also tested teleop procedures from Houston to make sure that having humans in the loop was also an effective way of completing tasks. Since full autonomy is vastly more difficult than almost full autonomy, occasional teleop is probably going to be critical for space robots of all kinds.

GITAI will apply the general-purpose autonomous space robotics technology, know-how, and experience acquired through this tech demo to develop extra-vehicular robotics EVR that can execute docking, repair, and maintenance tasks for On-Orbit Servicing OOS or conduct various activities for lunar exploration and lunar base construction.

I'm sure you did many tests with the system on the ground before sending it to the ISS. How was operating the robot on the ISS different from the testing you had done on Earth? The biggest difference between experiments on the ground and on the ISS is the microgravity environment, but it was not that difficult to cope with. However, experiments on the ISS, which is an unknown environment that we have never been to before, are subject to a variety of unexpected situations that were extremely difficult to deal with, for example an unexpected communication breakdown occurred due to a failed thruster firing experiment on the Russian module.

However, we were able to solve all the problems because the development team had carefully prepared for the irregularities in advance. It looked like the robot was performing many tasks using equipment designed for humans. Do you think it would be better to design things like screws and control panels to make them easier for robots to see and operate?

Yes, I think so. Unlike the ISS that was built in the past, it is expected that humans and robots will cooperate to work together in the lunar orbiting space station Gateway and the lunar base that will be built in the future.

Therefore, it is necessary to devise and implement an interface that is easy to use for both humans and robots. We are planning to conduct an on-orbit extra-vehicular demonstration in and a lunar demonstration in We are also working on space robot development projects for several customers for which we have already received orders. IBM approached a young Bill Gates for help. Legal trouble began. IBM responded with an agreement. Now Microsoft and IBM had a strained relationship. The rest is history.
