DARPA Director Arati Prabhakar in Conversation with John Markoff @CHM June 11, 2014

June 30th, 2014 by Alan Weissberger

 

Introduction:

This CHM conversation (with NY Times moderator  John Markoff asking the questions) was more about the challenges faced by Ms Arati Prabhakar, PhD then it was about DARPA.  It would’ve been very appropriate for a Women in Engineering meeting.  However, there were several important topics related to Ms Prabhaker’s two terms of employment at DARPA, which we’ve attempted to capture in this event summary article.  Note the addendum on Silicon Valley looking to recreate its past via companies establishing innovation labs.

Brief Backgrounder of Arati Prabhakar:

Growing up as an Indo-American in Lubbock, TX was quite challenging, but not nearly as difficult as being a woman in the EE curriculum at Texas Tech.  After obtaining a BSEE from Texas Tech, MSEE and PhD in Applied Physics from Cal Tech, Arati  Prabhakar started working on Silicon Gallium Arsenide (GaAs) projects at DARPA in 1986.  Ms Prabhakar later started the Microelectronics Office there during her first tour of employment.  It’s now called the Micro Systems Technology Office (MTO).  After leaving DARPA in 1993, she became the Director at NIST and then worked for a number of Silicon Valley firms, before returning to DARPA in July 2012 to become its 12th Director.

GaAs Projects at DARPA- then and now:

  • GaAs was of interest to DARPA in the mid 1990′s, because of its “radiation hardened”properties.
  • Bell Labs tried to build a 16K bit memory out of GaAs material.
  • GaAs was said to have higher electron mobility than traditional semiconductors, but that didn’t turn into a competitive advantage.
  • GaAS did blossom in RF devices used in the microwave world.  It is also used in advanced radar systems (see below).

Author’s Note: Advances in traditional MOS VLSI/ULSI technology precluded GaAs being used for many promising potential applications (e.g. high speed communications).  That’s because it was more expensive than MOS, used more circuit board space, and consumed more power.

  • GaAS arrays are used today to build advanced radar systems for military aircraft and ships.
  • The GaAs power amp in cell phones (which communicates with cell towers) traces back to GaAs research done decades ago at DARPA.
  • GaAs will also be used in the electronics within cell towers (Arati did not say how).
  • Gallium Nitride technology has come into full fruition and will be used in the next generation of military radar.

What has DARPA Done and What Are They Doing Now?

Arati Prabhakar noted the following points during her conversation with NY Times John Markoff and selected questions from the audience that followed:

  • We are at the end of Moore’s law and semiconductor companies are well aware of that.
  • The semiconductor industry has become totally globalized, especially manufacturing (Note: outside of Intel, most ICs are made in China, Taiwan or South Korea).
  • Geopolitical threats have refocused a lot of U.S. government research to counter-terrorism.
  • Most powerful technologies developed at DARPA disrupt and change the way the military works.  That may cause intransigence in accepting new technologies progressed by DARPA. “Here comes DARPA again…” some military people might say.
  • Over several decades,  DARPA has built a compelling track record which has earned them more respect and credibility from the U.S. military.
  • It’s not easy for DARPA to shift from stealth technology development or to move to precision guided weapons or infra-red night vision military systems.
  • DARPA’s Robotics Challenge is a contest that had its first trials last December. The winner will be decided in the finals which will take place “in about another year (2015).”
  • Such a “DARPA Challenge” is great way to interact and build technology for a greater community.
  • Ground robotics is an incredibly difficult challenge.  Bandwidth was being squeezed on and off to simulate an environment where there was no communications.  As a result, the robot couldn’t count on consistent communications (with the host computer).
  • DARPA invested $$$$ in Boston Dynamics which Google has now bought.  DARPA was very pleased with that.  “It’s a very promising sign,” Arati said.
  • There’s a long history of DARPA making investment in technologies to show what’s possible.  As the technology matures, private capital gets involved in the next stage.
  • Robotics will take massive private investments and real markets to become commercially viable.  It has tremendous potential to help the military on unmanned missions.
  • A robot developed by a Japanese start-up company named Schaft  (now owned by Google) won the DARPA Robot Rescue challenge last year.  Along with seven of the other top-scorers, Schaft can now apply for more DARPA funds to compete in next year’s finals.
  • DARPA’s budget is only 2% or 3% of all U.S. government R&D.  [That's amazingly less than what one might expect from the organization that created the ARPANET- the precursor to the Internet].
  • What is R&D?  At DARPA, it’s building proto-types and basic research into new areas that will open up technology opportunities.
  • How fragile are research technologies and industrial policies?  It all depends on the follow on use in the military and commercial worlds.
  • “The brain is a new (research) area for DARPA,” said moderator John Markoff. (Arati said below that DARPA has been investing in brain technologies for some time- so not really “a new area”).
  • “Biology is intersecting with physical science and information technology,” said Arati.  It has enormous potential to be the foundation for a whole new set of powerful technologies.  DARPA’s interest is in turning biology into technologies.
  • DARPA has been investing in neural technologies and brain function research for some time.  One application is to get prosthetics to U.S. veterans that have lost their limbs.
  • The human brain controls how our limbs move.  Understanding neural signaling that leads to motor control is a DARPA goal.  Three videos were shown to illustrate several DARPA neuroscience initiatives.  The first showed a prosthetic arm controlled by a human’s brain.  The videos can be seen along with the entire program on the CHM YouTube channel.  See link below.
  • DARPA is trying to figure out how the U.S. can be the most productive user of new technologies and what areas of technology the U.S. should be thinking about developing.
  • DARPA has invested in biological technologies for the last 20 years, starting with biological defense systems.
  • DARPA has created a Biological Technologies Office (BTO) to foster, demonstrate, and transition breakthrough fundamental research, discoveries, and computer science for national security.
  • Amazing things are happening in neuroscience and neuro-technology as well as in synthetic biology.  DARPA wants to turn those into scalable engineering practices (both in terms of time and production cost) so that they can be commercialized.
  • The ability to sequence and synthesize DNA is on an aggressive cost curve (although not a DARPA story) and that’s an ingredient in the synthetic biology world.
  • Arati is inspired by the progress she’s seen in lots of engineering disciplines that together have potential to unleash important new trends in biology.
  • But she’s chastened about how little we understand in biological involved complexity, especially when compared to IT and semiconductors.
  • Biology technologies are highly adaptable, but intractable when compared to transistors or lines of code.
  • Biology related research examples at the BTO include:  synthetic biology, brain work,  fighting infectious diseases.
  • Arati said that DARPA’s two main jobs were:

1]  Core mission is to pursue advanced technologies for use in the U.S.

2] Obligation to engage and raise technology issues so they get into the public eye, and  that a broader community can then decide how society uses the new technologies.

  • DARPA has a very substantial cyber-security portfolio.  DARPA is not responsible for operational security in the U.S.
  • “Patch and pray” is what we have (for operational national security in the U.S.) and we’re trying to do that ever faster.  DARPA wants to figure out technologies that give us a future with respect to cyber security.
  • DARPA’s focus is on the related security technologies that can be used for society to have a secure life and have the foundations for security in and away from home.
  • There are many attack vectors, because of the vastness of our information environment.  Therefore, there can’t be a single silver bullet security solution.  Rather, a layered set of many different security technologies are needed, which could be combined to thwart various security threats.
  • DARPA is working to scale formal methods to build “meaningful size Operating Systems (OS’s) that can be proven to be correct for specified security properties.”
  • DAPRA recently flew a drone in the courtyard of the Pentagon with an OS that has some properties that are unhackable now. “This could be the beginnings of a something that’s a big dream,” Arati said.
  • Current state of GPS:  It’s cheap and easy to gauge your position once the satellite is up in the sky. Military is addicted to it.  But new position, navigation and timing systems are also needed.
  • Future geo-location timing and navigation systems will be based on layered systems and “atom physics.”  The latter involves cooling atoms by shining lasers at them so that their atomic properties can be tapped.
  • The challenge is how to get these new geo-positioning and timing technologies from a huge room with researchers, to a shoe box size unit in a submarine.  A key objective is to minimize or eliminate drift in timing or position.
  • Quantum components in the way we smell have been researched at DARPA , but quantum computing “is not an active area” (as many thought).  Arati was not sure if anything is going on in quantum communications at DARPA.
  • Completely breaking complexity of massive platform military system is a DARPA goal. “They are un-Godly expensive, complex, and tightly coupled.”  The result might be visible in next generation fighter planes, in drones and what a soldier carries on his body.
  • DARPA has created the Mining and Understanding Software Enclaves (MUSE) program to reduce software complexity.
  • MUSE seeks to make significant advances in the way software is built, debugged, verified, maintained and understood. Central to its approach is the creation of a community infrastructure built around a large, diverse and evolving corpus of software drawn from the hundreds of billions of lines of open source code available today.  Automating assembly of code to do higher level functions is a goal.
  • Today, 2/3 of R&D investment is from private enterprises, rather than the 50/50 private/public sector split of several years ago.
  • Private R&D investment is growing faster than GDP [Note that doesn't take much with GDP growing at <2% for last 5 years since recession "ended" in June 2009]
  • Role of government is shifting when it comes to R&D investments.  The federal government is no longer the prime source of research, as it was for years and decades.  We now have incredibly innovative industries, Arati said (this author strongly disagrees).
  • Our ecosystem (the U.S. government, universities, and industry) is healthy.  We have adapted to change after change and she is optimistic that will  continue in the future.
  • How universities pursue research and what’s going to drive the educational system are key questions U.S. must address.
  • “Universities have always been a way that enables DARPA to get great things done,” Arati said to wrap up the program.

Comments from Richard Weiss, DARPA Director of Public Affairs (received July 4th via email):

I am surprised at the number of errors in your blog, especially since much of the relevant information is on DARPA’s website.

I don’t believe Arati would have said that one of DARPA’s two primary missions is “Obligation to engage and raise technology issues so they get into the public eye, e.g. how U.S. society uses the new technologies.”

DARPA is not a policy shop – it is a tech projects shop. So while DARPA does take seriously so-called ELSI obligations when a tech development raises societal questions, that is not a “primary mission” of DARPA.

It is incorrect (perhaps just sloppy sentence construction) to say that “Substantial cyber-security portfolio at DARPA is subject to “patch and pray.”” Certainly our portfolio is not “subject to” patch and pray. Our portfolio aims to improve upon the nation’s current reliance on “patch and pray” when it comes to cyber security.

………………………………………………………………………………………………

Author’s Response:  The post has been updated to reflect some of Mr. Weiss’ critiques (after carefully listening to the archived event webcast to verify accuracy of same).    Clarifications were also added (e.g. who said what) to avoid misunderstandings.

It’s my strong opinion that a reporter’s job is to accurately “report” what was said at an event.  An event summary is not a research paper where the company’s website is to be checked for accuracy or completeness or to validate/confirm what was said during the program.

Finally, you can check the archived event webcast to verify that Arati did say: “(It’s DARPA’s) Obligation to engage and raise technology issues so they get into the public eye…..”

Addendum: Excerpts from NY Times article- 

Silicon Valley Tries to Remake the Idea Machine (Bell Labs)

This superb article chronicles the decline of research amongst established silicon valley companies which have bought start-ups rather than invest in their own research labs (like the long gone AT&T Bell Labs or Xerox PARC).  But a resurgence is underway, starting with Google X.

A few excerpts from the article:

“The federal government now spends $126 billion a year on R. and D., according to the National Science Foundation. (It’s pocket change compared with the $267 billion that the private sector spends.) Asian economies now account for 34 percent of global spending; America’s share is 30 percent.”

“Most of the insurgent tech companies, with their razor focus on advancing the Internet, were too preoccupied to set up their own innovation labs. They didn’t have much of an incentive either. Start-ups became so cheap to create — founders can just rent space in the cloud from Amazon instead of buying servers and buildings to house them — that it became easier and more efficient for big companies to simply buy new ideas rather than coming up with the framework for inventing them. Some of Google’s largest businesses, like Android and Maps, were acquired. “M. and A. is the new R. and D.” became a popular catchphrase.”

“But in the past few years, the thinking has changed, and tech companies have begun looking to the past for answers. In 2010, Google opened Google X, where it is building driverless cars, Internet-connected glasses, balloons that deliver the Internet and other things straight out of science fiction. Microsoft Research just announced the opening of a skunk-works group called Special Projects. Even Bell Labs announced this month that it is trying to return to its original mission by finding far-out ways to solve real-world problems.”

“Instead of focusing on basic science research, “we’re tackling projects that advance science and solve significant problems,” says Regina Dugan, the former director of the Defense Advanced Research Projects Agency (Darpa), who now runs a small group inside Google called Advanced Technology and Projects. “What this means is you’re not compromising this idea of doing really important and interesting science and this sense of it really mattering.” To put a finer point on it, Astro Teller, who oversees Google X, told me: “We are not a research center. We think of ourselves as a moonshot factory, and the reasons for using that phrase is the word ‘moonshot’ reminds us to be audacious, and the word ‘factory’ reminds us we have to industrialize it in the end.””


Happy 50th Birthday S/360!

April 7th, 2014 by James Cortada

system360I consider this set of 150 products announced on April 7, 1964, to be the most important introduced by an American company in the 20th century. And I am not alone in that view.  How we used computers around the world was shaped directly by these machines and software, including your cell phone.  From IBM’s perspective, the firm doubled its revenues in 36 months and went on to be the dominant computer company for a generation.  For the computer industry, it grew at 19-20% compound rates over the next five years.  The architecture of this technology proved so pervasive that (a) computer scientists are still struggling with how to break through to a new paradigm or way of doing computing, (b) all mainframes still use software written by IBM in the 1960s, and (c) it made possible the hiring of perhaps the most unique IBMer in the 1970s – ME!!  Only with the massive diversification in the kinds of employees made possible by the success of this system did it make sense for IBM to bring in the diversified workforce that it did, including two people with Ph.D.s in history – ironically both trained in Spanish history.  The other fellow, also into sales, was an expert on the 1920s and 1930s, graduated out of the U of New Mexico, and worked in Detroit. He was hired a year before me.

 And that is the rest of the story.  Happy Birthday S/360!


The New Digital Age: Authors Eric Schmidt and Jared Cohen in Conversation with Facebook’s Sheryl Sandberg at CHM

March 10th, 2014 by Alan Weissberger

Introduction:

On March 3, 2014, Eric Schmidt and Jared Cohen (co-authors of The New Digital Age) engaged in a stimulating conversation with Facebook’s COO Sheryl Sandberg.  The event took place at the Computer History Museum (CHM) as part of the museum’s Revolutionary series (see description below).  This very interesting and wide ranging discussion, was mostly related to the promise and perils of the digital revolution, especially the Internet as it impacts the developing world. 

Eric Schmidt is the Executive Chairman and former CEO of Google. Jared Cohen is the Director of Google Ideas and a former adviser to Secretaries of State Condoleezza Rice and Hillary Clinton.  During the opening remarks, Schmidt jokingly said to Sheryl Sandberg:  “You’ve done all right for yourself since leaving Google.”

The New Digital Age‘s release in paperback provided the impetus for this CHM program.  This event was part of the CHM’s acclaimed Revolutionaries speaker series, featuring renowned innovators, business and technology leaders, and authors in enthralling conversations often with leading journalists.

Discussion:

There is good and bad in the many ways online technology is changing life around the globe, according to Schmidt.  The Internet empowers people in developing countries that mostly use smart phones for (wireless broadband) access, providing new opportunities for education, business, entertainment, news, etc.  But there are very real problems with regulating its use.  “With no central leaders in the world today, the Internet causes a huge control problem for free speech, morality and copyright protection,” he said.   “When does the Internet stop (i.e. get turned off) and bad stuff happen in countries like Syria and Ukraine/Crimea that are engaged in civil war?”

Cohen said that smart phones were confiscated by the military regime in Somalia and a friend of someone he met there was shot and killed for having pictures unfavorable to the regime on his smart phone.  More details in a bullet point below.

Here are a few key points made by the speakers:

  • On-line privacy talk may come before the sex talk for future generations of children.
  • Digital data permanence may spark the need for identity insurance and that’s somewhat scary.
  • Cyber-safety is a responsibility we bear globally for all, especially the non-tech savvy users.  Cyber-security requires agility and should not be compromised.
  • Schmidt: Suggests WiFi towers (with broadband backhaul) be built in 3rd world countries to provide ubiquitous Internet access and empower individuals living there.  That would have a positive impact on economic growth in the developing world.
  • Schmidt: There is a race between technology and humans, but humans are still debating last decades problems.
  • Schmidt: Technology has reduced the number of jobs, contributing to higher youth unemployment.
  • Schmidt: Displacement of manufacturing jobs by technology is an enduring trend which is a threat to current workers that have repetitive jobs (which might be done by a machine/robot).
  • Schmidt: We need some “social safety net” for displaced workers.  Todays solutions are not good enough!
  • In the future, a totally automated home -with many artificial intelligent devices- will likely happen.
  • Sandberg:  Women are 25% less likely than men to be on line, which puts them at an economic disadvantage.  (It wasn’t clear if that was for the U.S., developing countries or the entire world).
  • Sandberg: Micro-lending in the developing world has money managed by women.  They need smart phones to do that as there may only be wireless Internet access.
  • Sandberg: Giving inexpensive smart phones to women would solve many family problems.  Hundreds of millions of women would be empowered on-line.  Men would not be able to block women’s economic advancement in that case.
  • Cohen: In Syria, a wave of online videos couldn’t immediately stop repeated chemical weapons attacks on civilians. He also said troops have operated armed checkpoints where they forced people to turn over their cellphones for review.
  • The Google execs said that Internet technology made it easier for people like Julian Assange of Wikileaks and former National Security Agency contractor Edward Snowden to turn government secrets into public controversies. That’s not always desirable, the authors say, arguing that governments need to keep some secrets for national security.
  • Schmidt: There are near monopoly Internet service providers in the developing world and competition is needed to get cost effective Internet access.
  • Schmidt: Getting wireless networks upgraded for faster access, lower cost per user and capability to carry more traffic is a big challenge for developing countries (especially when there is no competition to drive that transition).
  • Schmidt: Maybe there are limits to what the Internet can do or be.

Backrounder: The New Digital Age:

In research for their book, Schmidt and Cohen traveled to more than 35 countries, including some of the world’s most volatile and repressive societies.  There they met with political leaders, entrepreneurs, and activists to learn firsthand about the challenges they face. They tackle some of the most interesting questions about our future: how will technology change privacy and security, war and intervention, diplomacy, revolution and terrorism? How will technology improve our lives? What new disruptions can we expect?

For the new paperback edition, Schmidt and Cohen added a new “afterword” to address a number of events, including the wave of revelations about government spying on Internet users, that played out after the book was first published in April 2013. The new section also responds to criticism from Wikileaks founder Julian Assange, who accused the co-authors of uncritically embracing U.S. foreign policy and of glossing over the threat that vast centralized databases pose to individual privacy and freedom.

Addendum: Most highlighted passages from “The New Digital Age” 

Personalization

“On the world stage, the most significant impact of the spread of communication technologies will be the way they help reallocate the concentration of power away from states and institutions and transfer it to individuals.”

Civilizational advance

“By 2025, the majority of the world’s population will, in one generation, have gone from having virtually no access to unfiltered information to accessing all of the world’s information through a device that fits in the palm of the hand.”

Identity

“Identity will be the most valuable commodity for citizens in the future, and it will exist primarily online.”

Anarchy

“The Internet is the largest experiment involving anarchy in history. Hundreds of millions of people are, each minute, creating and consuming an untold amount of digital content in an online world that is not truly bound by terrestrial laws.”

Loss of privacy

“The impact of this data revolution will be to strip citizens of much of their control over their personal information in virtual space, and that will have significant consequences in the physical world.”

Dissonance between technology and geopolitics

“In the months following our [Schmidt and Cohen's] trip [to Iraq], it became clear to us that there is a canyon dividing people who understand technology and people charged with addressing the world’s toughest geopolitical issues, and no one has built a bridge.”

Virtual reality

“In this book we aim to demonstrate ways in which the virtual world can make the physical world better, worse or just different.”

Personalization and customization

“The key advance ahead is personalization. You’ll be able to customize your devices—indeed, much of the technology around you—to fit your needs, so that your environment reflects your preferences.”

Humans, not machines control our destiny

“This is a book about technology, but even more, it’s a book about humans, and how humans interact with, implement, adapt to and exploit technologies in their environment, now and in the future, throughout the world. Most of all, this is a book about the importance of a guiding human hand in the new digital age. For all the possibilities that communication technologies represent, their use for good or ill depends solely on people. Forget all the talk about machines taking over. What happens in the future is up to us.”

Don’t say (or type, or “like”) anything you don’t want on the front of the NY Times

“Since information wants to be free, don’t write anything down you don’t want read back to you in court or printed on the front page of a newspaper, as the saying goes. In the future this adage will broaden to include not just what you say and write, but the websites you visit, who you include in your online network, what you “like,” and what others who are connected to you do, say and share.”

A Billion Programmers

February 24th, 2014 by Frederick Withington

When I first wrote programs in 1953, there was no software and few programmers. I entered programs in the computer’s binary language (octal notation) directly into the machine’s registers. And the machine was all mine: there was no operating system to allocate its resources among multiple programs or operate the input-output devices.

Then, programming aids and compliers evolved, and operating systems to allocate the computer’s resources. Programmers no longer dealt with the machine directly, but with an easier-to-use (maybe) interface. In some respects, programming got easier (anyway, it was a lot quicker) and many people learned to program.

Then the minicomputer and then the personal computer evolved, and three pivotal inventions occurred. Xerox PARC and Apple developed the desktop-icon interface, the spreadsheet was invented, and word processing was introduced. I feel that each made many more people into programmers.

The significance of the desktop, icon-based interface is obvious: as it has evolved over time, it has enabled generations of users to manage desktop and portable devices with minimal training.

I think the spreadsheet was equally important. An ordinary businessperson could populate the cells of a spreadsheet with limitless logical and mathematical processes, all invoked by the entry of a datum. Taken as a whole, a spreadsheet is a very complex and sophisticated program.

The significance of the word processor as a programming tool is less obvious, because in its basic form a word processor requires little programming by its user. But think of how it has grown. The word processor now enables its user to create and manipulate graphics of unlimited complexity, to format both virtual and hardcopy documents with three-dimensional structures, and to provide documents with interactive features, as in computer games. Surely when a user has created a word processing application with capabilities in all these areas, he/she has written a sophisticated program.

The Worldwide Web has created still more opportunities for programmers. The designers and builders of Web sites form a new, lucrative specialty. Even the people who create complex YouTube and Facebook posts are in a sense developing software.

What has happened is that human and machine languages have converged. The computer interface has become more intuitive, more symbolic and more flexible. At the same time much, if not most of the human race is learning about computer language as part of growing up. Booting up, managing and interconnecting computing devices; operating keyboards; selecting among icons; and interacting with the Internet and Web sites are activities performed by small children in all the more developed countries. All these children are being invited by the riches of the Web to try more experiments, to learn more, and to become more proficient programmers. Seamless Internet connections enable them to form teams, to cooperate, and to work together to exploit their best ideas. For instance, what will cloud programmers be able to do with shared 3-D printers?

I envy the trained programmers of the next generation, who will be able to search for inspiration among the contributions of billions of their less-trained fellows and create the software products of the future. We’ve seen nothing yet!


Approved IEEE Milestone: Birth of the 1st PC Operating System (CP/M)

January 22nd, 2014 by Alan Weissberger
Introduction:
Gary A. Kildall, PhD (1942 – 1994),  developed and then demonstrated the first working prototype of CP/M (Control Program for Microcomputers) in Pacific Grove in 1974. Together with his invention of the BIOS (Basic Input Output System), Kildall’s operating system allowed a microprocessor-based computer to communicate with a disk drive storage unit and provided an important foundation for the personal computer revolution.   This article reviews the history of CP/M and why it was so important.
A plaque to commemorate this IEEE Milestone will be installed in Pacific Grove, CA on April 25, 2014 with a brief ceremony that is scheduled to start at 2pm.  The  intended site for the plaque, a two-story Victorian residence at the corner of Lighthouse Avenue and Willow Street (Pacific Grove, CA). served as the DRI headquarters building from 1978 to 1991.  The leader of this milestone initiative was Dick Ahrons.  Brian Berg, Tom Rolander, and David Laws are working on the April 25th dedication program for this epic event.
Details on the  April 25th CP/M Milestone program will be posted as a comment when that event is formally announced.
History of CP/M:
In 1976, Gary Kildall incorporated Digital Research, Inc. (DRI) to commercialize the program and released version 1.3 of CP/M and BIOS.
CP/M was the first commercial operating system to allow a microprocessor-based computer to interface to a disk drive storage unit. CP/M played an important role in stimulating the hobbyist personal computer movement of the 1970s.  Its ability to support software programs on a wide variety of hardware configurations enabled early use of microcomputer systems from many different manufacturers in business and scientific applications. Microsoft DOS, as licensed to IBM for the original PC, was written to emulate the “look and feel” of CP/M. Thus CP/M was the forerunner of the operating systems that now power the majority of the world’s computers and led to the personal computing revolution.
The major challenge that Kildall had to overcome in the development of CP/M was the design and debugging of the “complex electronics … to make the diskette drive find certain locations and transfer data back and forth.”
BIOS, which is included in this IEEE milestone, was the first software run by a microprocessor based PC when powered on.   The BIOS software was “built into” the PC (stored in a Read Only Memory) and was the first software run by a PC when it powered on.The fundamental purposes of the BIOS were to initialize and test the system hardware components, and to load an Operating System from a disk drive (or other mass storage) into primary memory (core or semiconductor) that was accessed by the processor.  The BIOS provided an abstraction layer for the hardware, i.e. a consistent way for application programs and operating systems to interact with the keyboard, display, and other input/output devices. Variations in the system hardware were hidden by the BIOS from programs that used BIOS services.

………………………………………………………………………….

The following recollections are abstracted from pages 53 – 55 of “Computer Connections“, an unpublished autobiography that he wrote and distributed to friends and family in 1994. “Memorex … had come up with the new “floppy disk” to replace IBM punched cards. I stared at that damn diskette drive for hours on end … trying to figure a way to make it fly. I tried to build a diskette controller … but I, being mainly hardware inept … couldn’t get my controller to work. So I built an operting (sic) system program … I called it CP/M [but] I just couldn’t figure out how to make that damn disk drive work. Out of frustration, I called my good friend from the University of Washington, John Torode. He designed a neat little microcontroller and after a few months of testing that microcontroller started to work. We loaded my CP/M program from paper tape to the diskette and “booted” CP/M from the diskette, and up came the prompt *. This may have been one of the most exciting days of my life.”
Before Kildall’s development of CP/M, micro-computer manufacturers provided proprietary applications software that worked only on their own hardware. All programs had to be written from scratch to operate on each unique machine configuration. CP/M was initially designed to work on the Intel 8080 microprocessor and allowed computer systems built by any manufacturer who used that chip to run applications programs written by third-party suppliers. CP/M introduced a new element of competition into the computer marketplace that stimulated rapid growth in the use of low-cost systems in business, industry and academia and eventually in the home. According to Kildall, “CP/M was an instant success. By 1980, DRI had sold millions of copies of CP/M to manufacturers and end-users.”
Kildall’s own public account of the history of CP/M was published in Dr Dobbs Journal in 1980: THE EVOLUTION OF AN INDUSTRY: ONE PERSON’S VIEWPOINT, “Dr. Dobb’s Journal of Computer Calisthenics & Orthodontia”, Vol.5, No.1, (January 1980) (number 41), page 6-7.
Numerous popular accounts of the history of CP/M have been published in newspaper and magazine articles and in books, as well as online. Most of them focus on the fictitious story that DRI lost out to Microsoft on the IBM PC operating system decision in the summer of 1980, because Kildall had taken the day off to go flying. Kildall refutes this story in “Computer Connections” but it is probably most eloquently recounted in Harold Evans’ book on U.S. pioneers and innovators  “They Made America: Two Centuries of Innovators from the Steam Engine to the Search Engine” (2004) ISBN 0-316-27766-5.
According to that chapter (paraphrased here):
After Kildall’s wife Dorothy refused to sign IBM’s “ludicrously far reaching non disclosure agreement (NDA)”  in the morning of IBM’s visit to his home, Kildall and Tom Rolander met with IBM that same afternoon.  Once the NDA was agreed to and signed by Kildall, IBM revealed its plan.  Rolander demonstrated DRI’s MP/M-86 – the new multi-tasking Operating System for Intel’s 8086 microprocessor.  Rolander and Kildall wanted that OS to be the new defacto standard for microprocessor based OS’s as they believed multi-tasking was the wave of the future.
Negotiations began on how much IBM would pay DRI. Kildall believed they could strike a deal.  Kildall wrote, “We broke from the discussions, but nevertheless handshaking in general agreement of making a deal.”
That night, Kildall and his family went to the Caribbean for vacation.  When they returned home one week later, Gary called IBM in Boca Raton several times, but “they had gone off the air.”  IBM had gone back to Microsoft to make a deal on the latter’s PC operating system (PC-DOS which was later renamed MS-DOS).   Bill Gates allegedly told IBM that Kildall had not yet finished designing CP/M to run on a 16 bit microprocessor and that Microsoft could by itself meet IBM’s requirements.
Kildall and others claimed that PC-DOS had copied (and was therefore a clone of) CP/M.  DRI threatened to sue IBM for copyright infringement if they proceeded to use PC-DOS in the first IBM PC which was scheduled to be announced in four months (August 1981).
IBM offered to market CP/M-86 along with Microsoft’s PC-DOS (for the first IBM PC) on the condition that Kildall (DRI) would not sue IBM for infringement of CP/M copyrights.  IBM accepted that it would pay DRI a standard royalty rate (presumably for each copy of CP/M sold).
But Kildall did not know that IBM would screw them by making CP/M-86 prohibitively more expensive than PC-DOS which had a 6 to 1 price advantage – $40 vs $240.  IBM evidently had no intention of selling CP/M-86.  Kildall called IBM to request they reduce the price of CP/M, but no one called back.
Kildall wrote, “The pricing difference set by IBM killed CP/M-86.  I believe to this day that the entire (pricing) scenario was contrived by IBM to garner the existing standard at almost no cost.  Fundamental to this conspiracy was the plan to obtain the waiver for their own  PC-DOS produced by Microsoft.”
CP/M rapidly lost market share as the microcomputing market moved to the PC platform, and it never regained its former popularity. Byte magazine, at the time one of the leading industry magazines for microcomputers, essentially ceased covering CP/M products within a few years of the introduction of the IBM PC

Before CP/M there was PL/M:
Prior to the work on CP/M, Kildall consulted for Intel and National Semiconductor to help them adapt his PL/M+ compiler to their microprocessor development systems.  Unlike other contemporary languages such as Pascal, C or BASIC, PL/M had no standard input or output routines. It included features targeted at the low-level (microprocessor based) hardware, and could support direct access to any location in memory, I/O ports and microprocessor interrupt flags, in a very efficient manner. PL/M was the first high level programming language for microprocessor based computers and the original implementation language for the CP/M operating system.
+ PL/M was the first high level programming language for microprocessors. It was created by Kildall in 1972.
From the Gary Kildall chapter of the earlier referenced They Made America book:
“Intel was abuzz in 1973 with the triumph of the Intel 8008 chip, which doubled the power of its first microprocessor, and Kildall was drawn to spend more and more  time  there.  After his “eyeballs gave way”, he would  spend  the  night sleeping  in his Volkswagen van in the parking lot. He became a trader  in  an electronic  bazaar,  swapping  his software  skills  for  Intel’s  development hardware.  One morning, he knocked on the door of Hank Smith, the  manager  of Intel’s little software group, and told him he could make a compiler for the Intel 8008  microprocessor, so that his customers would not need to go  through  the drag  of low-level assembly language. Smith did not know what  Kildall  meant.
Kildall  showed how a compiler would enable an 8008 user to write  the  simple equation  x = y + z instead of several lines of low-level  assembly  language.  The manager called a customer he was courting, put the phone down and, with  a big  smile, uttered three words of great significance for the  development  of the Personal Computer: “Go for it!”
The  new  programming language, which  Kildall called  PL/M,  or  Programming  Language  for  Microcomputers,  was  immensely fruitful.   Intel  adopted  it,  and  Kildall  used  it  to  write   his  own microprocessor  applications, such as Operating Systems and utility  programs.
It  was the instrument for developing the PL/I-80 compiler that he  worked  on with  Dan  Davis for three years. “Gary was very visual”, Davis told  me.  “He would  design  things more or less graphically, and then transfer  his  design into code. He even had an aesthetic about his drawings. He was very  thorough, patient  and persistent in ensuring his solutions were not only  correct,  but elegant.”  Kildall’s  reward  was  Intel’s  small  new  computer  system,  the Intellec-8.”

Closing Comment:
This author knew Gary Kildall from 1973 to 1976 from his consulting work at National Semiconductor and the (1975 and 76) Asilomar MicroComputer Workshops.  Contrary to accounts of his being arrogant or aloof, he was just the opposite- gracious, polite, considerate and well behaved.  He did not come across as a hippie, but rather as a trustful academic.  At the 1975  Asilomar workshop, Kildall acknowledged and praised my work developing and demonstrating real time microprocessor applications at National Semiconductor.  He said I was doing great work there.  I felt very proud of myself that day and thanked Gary for his kind words.  IMHO, Kildall was a gentleman and a scholar, but evidently not a shrewd, cut-throat businessman.
