Architectural Engineering Quotes

The ideal architect should be a man of letters, a skillful draftsman, a mathematician, familiar with historical studies, a diligent student of philosophy, acquainted with music, not ignorant of medicine, learned in the responses of jurisconsults, familiar with astronomy and astronomical calculations.

I love doing it. Every building is like a person. Single and unrepeatable.

An architect knows something about everything. An engineer knows everything about one thing.

For the first time in architectural history, we're approaching the resolution and complexity of the natural world by creating new technologies that will ultimately enable us to design a beam as if it were a branch or an HVAC and waste removal system as if it were a photosynthetic GI tract engineered to convert carbon into biofuel.

When we're able to communicate in nature's language; when we're able to transcend the view that nature is a boundless entity; even transcending the building as the kernel of the architectural project; when we invite scientific inquiry and technological innovation, fusing atoms with bits and bits with genes - only then will the art of building enable new forms of interaction between humans and their environment. Only then will we be able to design, construct and evolve as equals.

A skyscraper is not a tree - not yet.

From a limited pallet of molecular components including cellulose, chitosan, and pectin; the very same materials found in trees, crustaceans and apple skins - natural systems embody an extensive array of functional materials that outperform human engineered ones through their resilience, sustainability and adaptability.

For centuries architects have been taught to sketch, model and build in three static dimensions - x, y and z. But the natural world offers contexts that are much more dimensionally complex and dynamic.

Since our divorce from nature with the industrial revolution, the major challenge for architecture remains a challenge of language as we replace units of growth with units of construction.

The Hedonistic Imperative outlines how genetic engineering and nanotechnology will abolish suffering in all sentient life. This project is ambitious but technically feasible. It is also instrumentally rational and ethically mandatory. The metabolic pathways of pain and malaise evolved only because they once served the fitness of our genes. They will be replaced by a different sort of neural architecture. States of sublime well-being are destined to become the genetically pre-programmed norm of mental health. The world's last aversive experience will be a precisely dateable event.

When we say that the ancestors of the Blacks, who today live mainly in Black Africa, were the first to invent mathematics, astronomy, the calendar, sciences in general, arts, religion, agriculture, social organization, medicine, writing, technique, architecture; that they were the first to erect buildings out of 6 million tons of stone (the Great Pyramid) as architects and engineers—not simply as unskilled laborers; that they built the immense temple of Karnak, that forest of columns with its famed hypostyle hall large enough to hold Notre-Dame and its towers; that they sculpted the first colossal statues (Colossi of Memnon, etc.)—when we say all that we are merely expressing the plain unvarnished truth that no one today can refute by arguments worthy of the name.

A basic principle of data processing teaches the folly of trying to maintain independent files in synchonism.

Nobody can understand the greatness of the thirteenth century, who does not realize that it was a great growth of new things produced by a living thing. In that sense it was really bolder and freer than what we call the renaissance, which was a resurrection of old things discovered in a dead thing... and the Gospel according to St. Thomas... was a new thrust like the titanic thrust of Gothic engineering; and its strength was in a God that makes all things new.

All race conditions, deadlock conditions, and concurrent update problems are due to mutable variables.

For a thing’s beauty we ought to compliment not its owner but its maker.

A digital computer is essentially a huge army of clerks, equipped with rule books, pencil and paper, all stupid and entirely without initiative, but able to follow millions of precisely defined operations. The difficulty lies in handing over the rule book.

In literature, too, we admire prose in which a small and astutely arranged set of words has been constructed to carry a large consignment of ideas. 'We all have strength enough to bear the misfortunes of others,' writes La Rochefoucauld in an aphorism which transports us with an energy and exactitude comparable to that of Maillard bridge. The Swiss engineer reduces the number of supports just as the French writer compacts into a single line what lesser minds might have taken pages to express. We delight in complexity to which genius has lent an appearance of simplicity. (p 207)

To speak in nature's language, we must prioritize bio-based structural materials; biopolymers. Biopolymers are natural polymers produced by the cells of living organisms. We're already utilizing them in products, pharma, and even in fashion. But to deploy them on the architectural scale, we need to invest in design and construction technologies that emulate their heirarchical properties by engineering real time chemical formation.

With us, our Priests are Administrators of all Business, Art, and Science; Directors of Trade, Commerce, Generalship, Architecture, Engineering, Education, Statesmanship, Legislature, Morality, Theology; doing nothing themselves, they are the Causes of everything worth doing, that is done by others.

In order to create a sustainable world, we need to: 1) Educate people. 2) Educate people. 3) Educate people. For every person left uneducated about the system of this sphere, the nature will make us all pay for it. Sustainability can only start in the mind.

The perfect kind of architecture decision is the one which never has to be made

He wanted to be deafened by the thunder of her engines, he needed to be drained of every thought by the cold, the noise, the equal amounts of boredom and adrenalin. He had believed once that he would be formed by the architecture of war, but now he realized, he had been erased by it.

Trying to design or reclaim places is, therefore, rather like trying to make or modify life itself. In this effort, it is wisest to adopt the gentle patient manner of an environmental midwife, while rejecting utterly the machine-driven arrogance of some environmental equivalent to a genetic engineer. By such gentle means places might flourish again, but also the world might become less threatened.

The intelligence we will create from the reverse-engineering of the brain will have access to its own source code and will be able to rapidly improve itself in an accelerating iterative design cycle. Although there is considerable plasticity in the biological human brain, as we have seen, it does have a relatively fixed architecture, which cannot be significantly modified, as well as a limited capacity. We are unable to increase its 300 million pattern recognizers to, say, 400 million unless we do so nonbiologically. Once we can achieve that, there will be no reason to stop at a particular level of capability. We can go on to make it a billion pattern recognizers, or a trillion.

Architecture must be carefully distinguished from implementation. As Blaauw has said, "Where architecture tells what happens, implementation tells how it is made to happen.

When a child has learned this architecture, he can tell time as easily from a wristwatch as from a church tower.

Conway’s law: Organizations which design systems … are constrained to produce designs which are copies of the communication structures of these organizations.

Only women could bleed without injury or death; only they rose from the gore each month like a phoenix; only their bodies were in tune with the ululations of the universe and the timing of the tides. Without this innate lunar cycle, how could men have a sense of time, tides, space, seasons, movement of the universe, or the ability to measure anything at all? How could men mistress the skills of measurement necessary for mathematics, engineering, architecture, surveying—and so many other professions? In Christian churches, how could males, lacking monthly evidence of Her death and resurrection, serve the Daughter of the Goddess? In Judaism, how could they honor the Matriarch without the symbol of Her sacrifices recorded in the Old Ovariment? Thus insensible to the movements of the planets and the turning of the universe, how could men become astronomers, naturalists, scientists—or much of anything at all?

Not exactly a certified philosopher—my degree is in engineering and architecture, but my true home was philosophy, and even at the Polytechnic I found some learned professors who guided my private readings.

Indeed, "brute force" solutions are often characteristic of advanced cultures, not primitive ones. The Romans and their predecessors spent a long time figuring out how to build arches... and virtually all our buildings today use post-and-lintel construction, precisely what the arch was devised to replace. We have better materials and more money, and given that, arches are usually not worth the extra complexity.

An architect is a generalist, not a specialist-the conductor of a symphony, not a virtuoso who plays every instrument perfectly. As a practitioner, an architect coordinates a team of professionals that include structural and mechanical engineers, interior designers, building-code consultants, landscape architects, specifications writers, contractors, and specialists from other disciplines. Typically, the interests of some team members will compete with the interests of others. An architect must know enough about each discipline to negotiate and synthesize competing demands while honoring the needs of the client and the integrity of the entire project.

Finding a taxi, she felt like a child pressing her nose to the window of a candy store as she watched the changing vista pass by while the twilight descended and the capital became bathed in a translucent misty lavender glow. Entering the city from that airport was truly unique. Charles de Gaulle, built nineteen miles north of the bustling metropolis, ensured that the final point of destination was veiled from the eyes of the traveller as they descended. No doubt, the officials scrupulously planned the airport’s location to prevent the incessant air traffic and roaring engines from visibly or audibly polluting the ambience of their beloved capital, and apparently, they succeeded. If one flew over during the summer months, the visitor would be visibly presented with beautifully managed quilt-like fields of alternating gold and green appearing as though they were tilled and clipped with the mathematical precision of a slide rule. The countryside was dotted with quaint villages and towns that were obviously under meticulous planning control. When the aircraft began to descend, this prevailing sense of exactitude and order made the visitor long for an aerial view of the capital city and its famous wonders, hoping they could see as many landmarks as they could before they touched ground, as was the usual case with other major international airports, but from this point of entry, one was denied a glimpse of the city below. Green fields, villages, more fields, the ground grew closer and closer, a runway appeared, a slight bump or two was felt as the craft landed, and they were surrounded by the steel and glass buildings of the airport. Slightly disappointed with this mysterious game of hide-and-seek, the voyager must continue on and collect their baggage, consoled by the reflection that they will see the metropolis as they make their way into town. For those travelling by road, the concrete motorway with its blue road signs, the underpasses and the typical traffic-logged hubbub of industrial areas were the first landmarks to greet the eye, without a doubt, it was a disheartening first impression. Then, the real introduction began. Quietly, and almost imperceptibly, the modern confusion of steel and asphalt was effaced little by little as the exquisite timelessness of Parisian heritage architecture was gradually unveiled. Popping up like mushrooms were cream sandstone edifices filigreed with curled, swirling carvings, gently sloping mansard roofs, elegant ironwork lanterns and wood doors that charmed the eye, until finally, the traveller was completely submerged in the glory of the Second Empire ala Baron Haussmann’s master plan of city design, the iconic grand mansions, tree-lined boulevards and avenues, the quaint gardens, the majestic churches with their towers and spires, the shops and cafés with their colourful awnings, all crowded and nestled together like jewels encrusted on a gold setting.

They came to me because they had finally realized, after years of observation and experience, that the highest-paid personnel in engineering are frequently not those who know the most about engineering. One can, for example, hire mere technical ability in engineering, accountancy, architecture or any other profession at nominal salaries. But the person who has technical knowledge plus the ability to express ideas, to assume leadership, and to arouse enthusiasm among people—that person is headed for higher earning power.

some of the very people who are developing search algorithms and architecture are willing to promote sexist and racist attitudes openly at work and beyond, while we are supposed to believe that these same employees are developing “neutral” or “objective” decision-making tools.

First, the probability of fire causing the total collapse of a steel-framed high-rise building is exceedingly low. Such an event has never occurred prior to or since September 11, 2001. On the other hand, every total collapse of a steel-framed high-rise building in history has been caused by controlled demolition.

If engineering cannot tell us what our houses should look like, nor in a pluralistic and non-deferential world can precedent or tradition, we must be free to pursue all stylistic options. We should acknowledge that the question of what is beautiful is both impossible to elucidate and shameful and even undemocratic to mention.

This is the philosophy of YAGNI: “You aren’t going to need it.” There is wisdom in this message, since over-engineering is often much worse than under-engineering. On the other hand, when you discover that you truly do need an architectural boundary where none exists, the costs and risks can be very high to add such a boundary.

Connascence, in the context of software engineering, refers to the degree of coupling between software components. (Connascence.io hosts a handy reference to the various types of connascence.) Software components are connascent if a change in one would require the other(s) to be modified in order to maintain the overall correctness of the system.

The reason for the difference between the architectural and engineering 'climate', so to speak, is very complex. It is partly a matter of terminology, partly a matter of historical accident, and the consequent training of architects and engineers, and mostly a matter of what is commonly supposed to be the difference in content or context - architecture being concerned with producing works of art; engineering with utility structures.

We tend to think of grand organizations like corporations or empires coming about through deliberate human planning: designing the conceptual architecture for each imposing structure, brick by brick. But the shape an institution ultimately takes is not so much designed in advance by a master engineer as it is carved away by challenges to its outer boundaries, the way a coastline is partly formed by an endless battering of much smaller waves.

There is a tendency to romanticize the abilities of the ancient Egyptians because they produced structures that were miraculous for their time and certainly would pose a serious challenge to ours. They were somehow immensely more talented with sticks and stones than modern researchers have been able to demonstrate using the same implements. When pondering the theories proffered by Egyptologists, one gets the impression that an ancient Egyptian quarry worker was like a maestro playing a complete symphony on a violin made of a cigar box and a stick and producing the quality of a Stradivarius. The argument is pleasing and poetic, but the trouble is that, metaphorically speaking, when modern scholars make a violin from a cigar box and a stick, its results are precisely what you would expect from a cigar box and a stick. So the question persists: From what instruments did the symphonic architecture of Egypt materialize?

It was in the library that he and May had always discussed the future of the children: the studies of Dallas and his young brother Bill, Mary's incurable indifference to "accomplishments," and passion for sport and philanthropy, and the vague leanings toward "art" which had finally landed the restless and curious Dallas in the office of a rising New York architect. The young men nowadays were emancipating themselves from the law and business and taking up all sorts of new things. If they were not absorbed in state politics or municipal reform, the chances were that they were going in for Central American archaeology, for architecture or landscape-engineering; taking a keen and learned interest in the prerevolutionary buildings of their own country, studying and adapting Georgian types, and protesting at the meaningless use of the word "Colonial." Nobody nowadays had "Colonial" houses except the millionaire grocers of the suburbs.

to, and some like the engineer never do get comfortable with them and use the less garish auditory side-doors; and the abundant sulcus-fissures and gyrus-bulges of the slick latex roof make rain-drainage complex and footing chancy at best, so there’s not a whole lot of recreational strolling up here, although a kind of safety-balcony of skull-colored polybutylene resin, which curves around the midbrain from the inferior frontal sulcus to the parietooccipital sulcus—a halo-ish ring at the level of like eaves, demanded by the Cambridge Fire Dept. over the heated pro-mimetic protests of topological Rickeyites over in the Architecture Dept. (which the M.I.T. administration, trying to placate Rickeyites and C.F.D. Fire Marshal both, had had the pre-molded resin injected with dyes to render it the distinctively icky brown-shot off-white of living skull, so that the balcony resembles at once corporeal bone and numinous aura)—which balcony means that

wheelchair-accessible front ramp, take a bit of getting used to, and some like the engineer never do get comfortable with them and use the less garish auditory side-doors; and the abundant sulcus-fissures and gyrus-bulges of the slick latex roof make rain-drainage complex and footing chancy at best, so there’s not a whole lot of recreational strolling up here, although a kind of safety-balcony of skull-colored polybutylene resin, which curves around the midbrain from the inferior frontal sulcus to the parietooccipital sulcus—a halo-ish ring at the level of like eaves, demanded by the Cambridge Fire Dept. over the heated pro-mimetic protests of topological Rickeyites over in the Architecture Dept.

When Dad wasn’t telling us about all the amazing things he had already done, he was telling us about the wondrous things he was going to do. Like build the Glass Castle. All of Dad’s engineering skills and mathematical genius were coming together in one special project: a great big house he was going to build for us in the desert. It would have a glass ceiling and thick glass walls and even a glass staircase. The Glass Castle would have solar cells on the top that would catch the sun’s rays and convert them into electricity for heating and cooling and running all the appliances. It would even have its own water-purification system. Dad had worked out the architecture and the floor plans and most of the mathematical calculations. He carried around the blueprints for the Glass Castle wherever we went, and sometimes he’d pull them out and let us work on the design for our rooms. All we had to do was find gold, Dad said, and we were on the verge of that. Once he finished the Prospector and we struck it rich, he’d start work on our Glass Castle.

In this section I have tried to demonstrate that Darwinian thinking does live up to its billing as universal acid: it turns the whole traditional world upside down, challenging the top-down image of designs flowing from that genius of geniuses, the Intelligent Designer, and replacing it with the bubble-up image of mindless, motiveless cyclical processes churning out ever-more robust combinations until they start replicating on their own, speeding up the design process by reusing all the best bits over and over. Some of these earliest offspring eventually join forces (one major crane, symbiosis), which leads to multicellularity (another major crane), which leads to the more effective exploration vehicles made possible by sexual reproduction (another major crane), which eventually leads in one species to language and cultural evolution (cranes again), which provide the medium for literature and science and engineering, the latest cranes to emerge, which in turn permits us to “go meta” in a way no other life form can do, reflecting in many ways on who and what we are and how we got here, modeling these processes in plays and novels, theories and computer simulations, and ever-more thinking tools to add to our impressive toolbox. This perspective is so widely unifying and at the same time so generous with detailed insights that one might say it’s a power tool, all on its own. Those who are still strangely repelled by Darwinian thinking must consider the likelihood that if they try to go it alone with only the hand tools of tradition, they will find themselves laboring far from the cutting edge of research on important phenomena as diverse as epidemics and epistemology, biofuels and brain architecture, molecular genetics, music, and morality.

it was with a palpable sense of excitement that Woolly realized they were suddenly approaching the Brooklyn Bridge with every intention of driving across it. How truly majestic was its architecture, thought Woolly. How inspiring the cathedral-like buttresses and the cables that soared through the air. What a feat of engineering, especially since it had been built back in eighteen something-something, and ever since had supported the movement of multitudes from one side of the river to the other and back again, every single day. Surely, the Brooklyn Bridge deserved to be on the List.

Many researchers, who have been conditioned to using cognitive models, might not initially see the difference between “levels” and “layers.” With levels, processes are sequential (or, as electrical engineers would say, “in series”), while with a layered architecture, processing goes on simultaneously (“in parallel”). When processing through levels, all the steps are performed one after another, like a baton relay. You need one level to finish before the next one up can start. Processing in layers, on the other hand, can have all the runners leave at the same time and go different places. This change in architecture makes for big differences.

It’s hard to blame Representative Petri for missing the point. The value of studying fireflies is endlessly surprising. For example, before 1994, Internet engineers were vexed by spontaneous pulsations in the traffic between computers called routers, until they realized that the machines were behaving like fireflies, exchanging periodic messages that were inadvertently synchronizing them. Once the cause was identified, it became clear how to relieve the congestion. Electrical engineers devised a decentralized architecture for clocking computer circuits more efficiently, by mimicking the fireflies’ strategy for achieving synchrony at low cost and high reliability.

Modern architects and engineers are still trying to understand how the ancient Greeks were able to build the Parthenon in ten years when the restoration of the monument has continued for more than three decades and is still not complete. What they have learned and shared along this arduous path of rediscovery is that the Greeks were highly skilled at building visual compensations into their structures. Columns were crafted and positioned to compensate for how the eye interprets what it sees at a distance. Subtle variances in the surface of platforms, columns, and colonnades provide the appearance of geometric proportion, whereas if they had worked from the perspective of a flat datum surface, the brain would interpret the results as being slightly skewed.

The ideal of progress also should not be confused with the 20th-century movement to re-engineer society for the convenience of technocrats and planners, which the political scientist James Scott calls Authoritarian High Modernism.14 The movement denied the existence of human nature, with its messy needs for beauty, nature, tradition, and social intimacy. Starting from a “clean tablecloth,” the modernists designed urban renewal projects that replaced vibrant neighborhoods with freeways, high-rises, windswept plazas, and brutalist architecture. “Mankind will be reborn,” they theorized, and “live in an ordered relation to the whole.” Though these developments were sometimes linked to the word progress, the usage was ironic: “progress” unguided by humanism is not progress.

Facebook’s own North American marketing director, Michelle Klein, who told an audience in 2016 that while the average adult checks his or her phone 30 times a day, the average millennial, she enthusiastically reported, checks more than 157 times daily. Generation Z, we now know, exceeds this pace. Klein described Facebook’s engineering feat: “a sensory experience of communication that helps us connect to others, without having to look away,” noting with satisfaction that this condition is a boon to marketers. She underscored the design characteristics that produce this mesmerizing effect: design is narrative, engrossing, immediate, expressive, immersive, adaptive, and dynamic.11 If you are over the age of thirty, you know that Klein is not describing your adolescence, or that of your parents, and certainly not that of your grandparents. Adolescence and emerging adulthood in the hive are a human first, meticulously crafted by the science of behavioral engineering; institutionalized in the vast and complex architectures of computer-mediated means of behavior modification; overseen by Big Other; directed toward economies of scale, scope, and action in the capture of behavioral surplus; and funded by the surveillance capital that accrues from unprecedented concentrations of knowledge and power. Our children endeavor to come of age in a hive that is owned and operated by the applied utopianists of surveillance capitalism and is continuously monitored and shaped by the gathering force of instrumentarian power. Is this the life that we want for the most open, pliable, eager, self-conscious, and promising members of our society?

Search engines and social networks are analog computers of unprecedented scale. Information is being encoded (and operated upon) as continuous (and noise-tolerant) variables such as frequencies (of connection or occurrence) and the topology of what connects where, with location being increasingly defined by a fault-tolerant template rather than by an unforgiving numerical address. Pulse-frequency coding for the Internet is one way to describe the working architecture of a search engine, and PageRank for neurons is one way to describe the working architecture of the brain. These computational structures use digital components, but the analog computing being performed by the system as a whole exceeds the complexity of the digital code on which it runs. The model (of the social graph, or of human knowledge) constructs and updates itself.

We like to think of ourselves as immune from influence or our cognitive biases, because we want to feel like we are in control, but industries like alcohol, tobacco, fast food, and gaming all know we are creatures that are subject to cognitive and emotional vulnerabilities. And tech has caught on to this with its research into “user experience,” “gamification,” “growth hacking,” and “engagement” by activating ludic loops and reinforcement schedules in the same way slot machines do. So far, this gamification has been contained to social media and digital platforms, but what will happen as we further integrate our lives with networked information architectures designed to exploit evolutionary flaws in our cognition? Do we really want to live in a “gamified” environment that engineers our obsessions and plays with our lives as if we are inside its game?

It turns out that thousands of new hippocampus cells are born naturally each day, but most die soon afterward. However, it was shown that rats that learned new skills retained more of their new cells. A combination of exercise and mood-elevating chemicals can also boost the survival rate of new hippocampus cells. It turns out that stress, on the contrary, accelerates the death of new neurons. In 2007, a breakthrough occurred when scientists in Wisconsin and Japan were able to take ordinary human skin cells, reprogram their genes, and turn them into stem cells. The hope is that these stem cells, either found naturally or converted using genetic engineering, can one day be injected into the brains of Alzheimer’s patients to replace dying cells. (These new brain cells, because they do not yet have the proper connections, would not be integrated into the brain’s neural architecture. This means that a person would have to relearn certain skills to incorporate these fresh new neurons.)

I propose that what we call “consciousness” is a feeling forming a backdrop to, or attached to, a current mental event or instinct. It is best grasped by considering a common engineering architecture called layering, which allows complex systems to function efficiently and in an integrated fashion, from atoms to molecules, to cells, to circuits, to cognitive and perceptual capacities. If the brain indeed consists of different layers (in the engineering sense), then information from a micro level may be integrated at higher and higher layers until each modular unit itself produces consciousness. A layer architecture allows for new levels of functioning to arise from lower-level functioning parts that could not create the “higher level” experience alone. It is time to learn more about layering and the wonders it brings to understanding brain architecture. We are on the road to realizing that consciousness is not a “thing.” It is the result of a process embedded in an architecture, just as a democracy is not a thing but the result of a process.

Nowadays, whether we like it or not, we are stuck with one form or another of advanced technology and we have got to make it work safely and efficiently: this involves, among other things, the intelligent application of structural theory. However, man does not live by safety and efficiency alone, and we have to face the fact that, visually, the world is becoming an increasingly depressing place. It is not, perhaps, so much the occurrence of what might be described as 'active ugliness' as the prevalence of the dull and the commonplace. Far too seldom is the heart rejoiced or does one feel any better or happier for looking at the works of modern man. Yet most of the artefacts of the eighteenth century, even quite humble and trivial ones, seem to many of us to be at least pleasing and sometimes incomparably beautiful. To that extent people—all people—in the eighteenth century lived richer lives than most of us do today. This is reflected in the prices we pay nowadays for period houses and antiques. A society which was more creative and self-confident would not feel quite so strong a nostalgia for its great-grandfathers' buildings and household looks.

By the architecture of a system, I mean the complete and detailed specification of the user interface. For a computer this is the programming manual. For a compiler it is the language manual. For a control program it is the manuals for the language or languages used to invoke its functions. For the entire system it is the union of the manuals the user must consult to do his entire job. The architect of a system, like the architect of a building, is the user's agent. It is his job to bring professional and technical knowledge to bear in the unalloyed interest of the user, as opposed to the interests of the salesman, the fabricator, etc.[2] Architecture must be carefully distinguished from implementation. As Blaauw has said, "Where architecture tells what happens, implementation tells how it is made to happen."[3] He gives as a simple example a clock, whose architecture consists of the face, the hands, and the winding knob. When a child has learned this architecture, he can tell time as easily from a wristwatch as from a church tower. The implementation, however, and its realization, describe what goes on inside the case—powering by any of many mechanisms and accuracy control by any of many.

2006 interview by Jim Gray, Amazon CTO Werner Vogels recalled another watershed moment: We went through a period of serious introspection and concluded that a service-oriented architecture would give us the level of isolation that would allow us to build many software components rapidly and independently. By the way, this was way before service-oriented was a buzzword. For us service orientation means encapsulating the data with the business logic that operates on the data, with the only access through a published service interface. No direct database access is allowed from outside the service, and there’s no data sharing among the services.3 That’s a lot to unpack for non–software engineers, but the basic idea is this: If multiple teams have direct access to a shared block of software code or some part of a database, they slow each other down. Whether they’re allowed to change the way the code works, change how the data are organized, or merely build something that uses the shared code or data, everybody is at risk if anybody makes a change. Managing that risk requires a lot of time spent in coordination. The solution is to encapsulate, that is, assign ownership of a given block of code or part of a database to one team. Anyone else who wants something from that walled-off area must make a well-documented service request via an API.

Rome was not the first state of organized gangsterdom, nor was it the last; but it was the only one that managed to bamboozle posterity into an almost universal admiration. Few rational men admire the Huns, the Nazis or the Soviets; but for centuries, schoolboys have been expected to read Julius Caesar's militaristic drivel ("We inflicted heavy losses upon the enemy, our own casualties being very light") and Cato's revolting incitements to war. They have been led to believe that the Romans had attained an advanced level in the sciences, the arts, law, architecture, engineering and everything else. It is my opinion that the alleged Roman achievements are largely a myth; and I feel it is time for this myth to be debunked a little. What the Romans excelled in was bullying, bludgeoning, butchering and blood baths. Like the Soviet Empire, the Roman Empire enslaved peoples whose cultural level was far above their own. They not only ruthlessly vandalized their countries, but they also looted them, stealing their art treasures, abducting their scientists and copying their technical know-how, which the Romans' barren society was rarely able to improve on. No wonder, then, that Rome was filled with great works of art. But the light of culture which Rome is supposed to have emanated was a borrowed light: borrowed from the Greeks and the other peoples that the Roman militarists had enslaved.

Stanford University’s John Koza, who pioneered genetic programming in 1986, has used genetic algorithms to invent an antenna for NASA, create computer programs for identifying proteins, and invent general purpose electrical controllers. Twenty-three times Koza’s genetic algorithms have independently invented electronic components already patented by humans, simply by targeting the engineering specifications of the finished devices—the “fitness” criteria. For example, Koza’s algorithms invented a voltage-current conversion circuit (a device used for testing electronic equipment) that worked more accurately than the human-invented circuit designed to meet the same specs. Mysteriously, however, no one can describe how it works better—it appears to have redundant and even superfluous parts. But that’s the curious thing about genetic programming (and “evolutionary programming,” the programming family it belongs to). The code is inscrutable. The program “evolves” solutions that computer scientists cannot readily reproduce. What’s more, they can’t understand the process genetic programming followed to achieve a finished solution. A computational tool in which you understand the input and the output but not the underlying procedure is called a “black box” system. And their unknowability is a big downside for any system that uses evolutionary components. Every step toward inscrutability is a step away from accountability, or fond hopes like programming in friendliness toward humans. That doesn’t mean scientists routinely lose control of black box systems. But if cognitive architectures use them in achieving AGI, as they almost certainly will, then layers of unknowability will be at the heart of the system. Unknowability might be an unavoidable consequence of self-aware, self-improving software.

Bell resisted selling Texas Instruments a license. “This business is not for you,” the firm was told. “We don’t think you can do it.”38 In the spring of 1952, Haggerty was finally able to convince Bell Labs to let Texas Instruments buy a license to manufacture transistors. He also hired away Gordon Teal, a chemical researcher who worked on one of Bell Labs’ long corridors near the semiconductor team. Teal was an expert at manipulating germanium, but by the time he joined Texas Instruments he had shifted his interest to silicon, a more plentiful element that could perform better at high temperatures. By May 1954 he was able to fabricate a silicon transistor that used the n-p-n junction architecture developed by Shockley. Speaking at a conference that month, near the end of reading a thirty-one-page paper that almost put listeners to sleep, Teal shocked the audience by declaring, “Contrary to what my colleagues have told you about the bleak prospects for silicon transistors, I happen to have a few of them here in my pocket.” He proceeded to dunk a germanium transistor connected to a record player into a beaker of hot oil, causing it to die, and then did the same with one of his silicon transistors, during which Artie Shaw’s “Summit Ridge Drive” continued to blare undiminished. “Before the session ended,” Teal later said, “the astounded audience was scrambling for copies of the talk, which we just happened to bring along.”39 Innovation happens in stages. In the case of the transistor, first there was the invention, led by Shockley, Bardeen, and Brattain. Next came the production, led by engineers such as Teal. Finally, and equally important, there were the entrepreneurs who figured out how to conjure up new markets. Teal’s plucky boss Pat Haggerty was a colorful case study of this third step in the innovation process.

The granite complex inside the Great Pyramid, therefore, is poised ready to convert vibrations from the Earth into electricity. What is lacking is a sufficient amount of energy to drive the beams and activate the piezoelectric properties within them. The ancients, though, had anticipated the need for more energy than what would be collected only within the King's Chamber. They had determined that they needed to tap into the vibrations of the Earth over a larger area inside the pyramid and deliver that energy to the power center—the King's Chamber —thereby substantially increasing the amplitude of the oscillations of the granite. Modern concert halls are designed and built to interact with the instruments performing within. They are huge musical instruments in themselves. The Great Pyramid can be seen as a huge musical instrument with each element designed to enhance the performance of the other. While modern research into architectural acoustics might focus predominantly upon minimizing the reverberation effects of sound in enclosed spaces, there is reason to believe that the ancient pyramid builders were attempting to achieve the opposite. The Grand Gallery, which is considered to be an architectural masterpiece, is an enclosed space in which resonators were installed in the slots along the ledge that runs the length of the gallery. As the Earth's vibration flowed through the Great Pyramid, the resonators converted the vibrational energy to airborne sound. By design, the angles and surfaces of the Grand Gallery walls and ceiling caused reflection of the sound, and its focus into the King's Chamber. Although the King's Chamber also was responding to the energy flowing through the pyramid, much of the energy would flow past it. The specific design and utility of the Grand Gallery was to transfer the energy flowing through a large area of the pyramid into the resonant King's Chamber. This sound was then focused into the granite resonating cavity at sufficient amplitude to drive the granite ceiling beams to oscillation. These beams, in turn, compelled the beams above them to resonate in harmonic sympathy. Thus, with the input of sound and the maximization of resonance, the entire granite complex, in effect, became a vibrating mass of energy.

In 1910 Leroux had his greatest literary success with Le Fantôme de l’Opéra (The Phantom of the Opera). This is both a detective story and a dark romantic melodrama and was inspired by Leroux’s passion for and obsession with the Paris Opera House. And there is no mystery as to why he found the building so fascinating because it is one of the architectural wonders of the nineteenth century. The opulent design and the fantastically luxurious furnishings added to its glory, making it the most famous and prestigious opera house in all Europe. The structure comprises seventeen floors, including five deep and vast cellars and sub cellars beneath the building. The size of the Paris Opera House is difficult to conceive. According to an article in Scribner’s Magazine in 1879, just after it first opened to the public, the Opera House contained 2,531 doors with 7,593 keys. There were nine vast reservoirs, with two tanks holding a total of 22,222 gallons of water. At the time there were fourteen furnaces used to provide the heating, and dressing-rooms for five hundred performers. There was a stable for a dozen or so horses which were used in the more ambitious productions. In essence then the Paris Opera House was like a very small magnificent city. During a visit there, Leroux heard the legend of a bizarre figure, thought by many to be a ghost, who had lived secretly in the cavernous labyrinth of the Opera cellars and who, apparently, engineered some terrible accidents within the theatre as though he bore it a tremendous grudge. These stories whetted Leroux’s journalistic appetite. Convinced that there was some truth behind these weird tales, he investigated further and acquired a series of accounts relating to the mysterious ‘ghost’. It was then that he decided to turn these titillating titbits of theatre gossip into a novel. The building is ideal for a dark, fantastic Grand Guignol scenario. It is believed that during the construction of the Opera House it became necessary to pump underground water away from the foundation pit of the building, thus creating a huge subterranean lake which inspired Leroux to use it as one of his settings, the lair, in fact, of the Phantom. With its extraordinary maze-like structure, the various stage devices primed for magical stage effects and that remarkable subterranean lake, the Opera House is not only the ideal backdrop for this romantic fantasy but it also emerges as one of the main characters of this compelling tale. In using the real Opera House as its setting, Leroux was able to enhance the overall sense of realism in his novel.

These needs, then, are just as real as any other requirements; we refer to them here as required constraints or design constraints, and they are a very important part of the whole requirements set.

The point is best made by stating that not all systems are requirements-driven, at least, not driven by formal written requirements of the kind we have described so far [Rechtin 97]. As an example: A city is a people-made system, but (with a few notable exceptions) no one actually sits down and writes a set of requirements for a city, and then builds it. Rather, cities evolve over time, starting as small settlements exploiting favorable locations or natural resources, and growing as new facilities are added and more people decide to move in. It is most unlikely that the original settlers on Manhattan Island ever dreamed what their creation would grow into!

Ask residents of Manhattan what functions the city provides for them, and they will give you an impressive list. Do this for all the various stakeholders in the city, and you will have a pretty good set of requirements for Manhattan. This would be a useful exercise for city planners or for anyone considering starting a business in the city. In summary, then, the fact that not all systems are requirements-driven does not diminish the value of analyzing requirements. Whether we carry out the analysis before or after the system exists, it still has great benefits.

Every McDonald’s, for instance, looks the same—the company deliberately tries to standardize stores’ architecture and what employees say to customers, so everything is a consistent cue to trigger eating routines. The foods at some chains are specifically engineered to deliver immediate rewards—the fries, for instance, are designed to begin disintegrating the moment they hit your tongue, in order to deliver a hit of salt and grease as fast as possible, causing your pleasure centers to light up and your brain to lock in the pattern.

Just look at the architecture," Dr Hartmann explained. Blueprint your feet, and you'll find a marvel that engineers have been trying to match for centuries. Your foot's centerpiece is the arch, the greastest weight-bearing design ever created. The beauty of any arch is the way it gets stronger under stress. The harder you push down, the tighter its parts mesh. No stonemason worth his trowel would ever stick a support under an arch; push up from underneath, and you weaken the whole structure. Buttressing the foot's arch from all sides is a high-tensile web of twenty-six bones, thirty-three joints, twelve rubbery tendons, and eighteen muscles, all stretching and flexing like an earthquake resistant suspension bridge.

Aldus Barnes, a structural engineer by training and member of the Advanced Geometry Unit (AGU) at Arup, has formed many successful collaborations and earned a prominent place for himself in architecture by adopting the language and skills of architects. "Talk in terms of texture and density, instead of torsion and shear. That way they don't think you are just another nerd," Barnes advises the young members of his team.

Software architecture is the set of design decisions which, if made incorrectly, may cause your project to be cancelled.

These comments recall Turkle's distinction between two kinds of "transparency" in technological cultures. Modernist transparency is the notion that users can and should have access to the inner workings of a technology. It evokes the aesthetic of early relationships with cars in which one could "open the hood and see inside." Turkle contrasts this with an opposing, post-modern meaning of the term - the notion that something is transparent if you can use it without knowing how it works. Post-modern transparency allows the user to navigate the surface of a system without ever having to access its underlying mechanics. Are young engineers more susceptible to post-modern ways of seeing simulation?

By shifting the empirical emphasis from the search for mental faculties as unified neurobiological categories towards developing a more componential, constructionist functional architecture of the human brain, the overlap in empirical findings across psychological domains is not a problem for reverse inference, but becomes the engine that drives a more valid approach to reverse inference.

Standing before costly objects of technological beauty, we may be tempted to reject the possibility of awe, for fear that we could grow stupid through admiration. We may feel at risk of becoming overimpressed by architecture and engineering, of being dumbstruck by the Bombardier trains that progress driverlessly between satellites or by the General Electric GE90 engines that hang lightly off the composite wings of a Boeing 777 bound for Seoul. And yet to refuse to be awed at all might in the end be merely another kind of foolishness.

Tracked Vehicles "Each war proves anew to those who may have had their doubts, the primacy of the main battle tank. Between wars, the tank is always a target for cuts. But in wartime, everyone remembers why we need it, in its most advanced, upgraded versions and in militarily significant numbers." - IDF Brigadier General Yahuda Admon (retired) Since their first appearance in the latter part of World War I, tanks have increasingly dominated military thinking. Armies became progressively more mechanised during World War II, with many infantry being carried in armoured carriers by the end of the war. The armoured personnel carrier (APC) evolved into the infantry fighting vehicle (IFV), which is able to support the infantry as well as simply transport them. Modern IFVs have a similar level of battlefield mobility to the tanks, allowing tanks and infantry to operate together and provide mutual support. Abrams Mission Provide heavy armour superiority on the battlefield. Entered Army Service 1980 Description and Specifications The Abrams tank closes with and destroys enemy forces on the integrated battlefield using mobility, firepower, and shock effect. There are three variants in service: M1A1, M1A2 and M1A2 SEP. The 120mm main gun, combined with the powerful 1,500 HP turbine engine and special armour, make the Abrams tank particularly suitable for attacking or defending against large concentrations of heavy armour forces on a highly lethal battlefield. Features of the M1A1 modernisation program include increased armour protection; suspension improvements; and an improved nuclear, biological and chemical (NBC) protection system that increases survivability in a contaminated environment. The M1A1D modification consists of an M1A1 with integrated computer and a far-target-designation capability. The M1A2 modernisation program includes a commander's independent thermal viewer, an improved commander's weapon station, position navigation equipment, a distributed data and power architecture, an embedded diagnostic system and improved fire control systems.

In one set of experiments, for example, researchers affiliated with the National Institute on Alcohol Abuse and Alcoholism trained mice to press levers in response to certain cues until the behavior became a habit. The mice were always rewarded with food. Then, the scientists poisoned the food so that it made the animals violently ill, or electrified the floor, so that when the mice walked toward their reward they received a shock. The mice knew the food and cage were dangerous—when they were offered the poisoned pellets in a bowl or saw the electrified floor panels, they stayed away. When they saw their old cues, however, they unthinkingly pressed the lever and ate the food, or they walked across the floor, even as they vomited or jumped from the electricity. The habit was so ingrained the mice couldn’t stop themselves.1.23 It’s not hard to find an analog in the human world. Consider fast food, for instance. It makes sense—when the kids are starving and you’re driving home after a long day—to stop, just this once, at McDonald’s or Burger King. The meals are inexpensive. It tastes so good. After all, one dose of processed meat, salty fries, and sugary soda poses a relatively small health risk, right? It’s not like you do it all the time. But habits emerge without our permission. Studies indicate that families usually don’t intend to eat fast food on a regular basis. What happens is that a once a month pattern slowly becomes once a week, and then twice a week—as the cues and rewards create a habit—until the kids are consuming an unhealthy amount of hamburgers and fries. When researchers at the University of North Texas and Yale tried to understand why families gradually increased their fast food consumption, they found a series of cues and rewards that most customers never knew were influencing their behaviors.1.24 They discovered the habit loop. Every McDonald’s, for instance, looks the same—the company deliberately tries to standardize stores’ architecture and what employees say to customers, so everything is a consistent cue to trigger eating routines. The foods at some chains are specifically engineered to deliver immediate rewards—the fries, for instance, are designed to begin disintegrating the moment they hit your tongue, in order to deliver a hit of salt and grease as fast as possible, causing your pleasure centers to light up and your brain to lock in the pattern. All the better for tightening the habit loop.1.25 However, even these habits are delicate. When a fast food restaurant closes down, the families that previously ate there will often start having dinner at home, rather than seek out an alternative location. Even small shifts can end the pattern. But since we often don’t recognize these habit loops as they grow, we are blind to our ability to control them. By learning to observe the cues and rewards, though, we can change the routines.

The first mile was torture. I passed beneath the massive stone arch at the entrance to the school, pulled off the road and threw up. I felt better and ran down the long palm-lined drive to the Old Quad. Lost somewhere in the thicket to my left was the mausoleum containing the remains of the family by whom the university had been founded. Directly ahead of me loomed a cluster of stone buildings, the Old Quad. I stumbled up the steps and beneath an archway into a dusty courtyard which, with its clumps of spindly bushes and cacti, resembled the garden of a desert monastery. All around me the turrets and dingy stone walls radiated an ominous silence, as if behind each window there stood a soldier with a musket waiting to repel any invader. I looked up at the glittering facade of the chapel across which there was a mosaic depicting a blond Jesus and four angels representing Hope, Faith, Charity, and, for architectural rather than scriptural symmetry, Love. In its gloomy magnificence, the Old Quad never failed to remind me of the presidential palace of a banana republic. Passing out of the quad I cut in front of the engineering school and headed for a back road that led up to the foothills. There was a radar installation at the summit of one of the hills called by the students the Dish. It sat among herds of cattle and the ruins of stables. It, too, was a ruin, shut down for many years, but when the wind whistled through it, the radar produced a strange trilling that could well be music from another planet. The radar was silent as I slowed to a stop at the top of the Dish and caught my breath from the upward climb. I was soaked with sweat, and my headache was gone, replaced by giddy disorientation. It was a clear, hot morning. Looking north and west I saw the white buildings, bridges and spires of the city of San Francisco beneath a crayoned blue sky. The city from this aspect appeared guileless and serene. Yet, when I walked in its streets what I noticed most was how the light seldom fell directly, but from angles, darkening the corners of things. You would look up at the eaves of a house expecting to see a gargoyle rather than the intricate but innocent woodwork. The city had this shadowy presence as if it was a living thing with secrets and memories. Its temperament was too much like my own for me to feel safe or comfortable there. I looked briefly to the south where San Jose sprawled beneath a polluted sky, ugly and raw but without secrets or deceit. Then I stretched and began the slow descent back into town.

But if tools were actually central to mental growth beyond purely animal needs, how is it that those primitive peoples, like the Australian Bushmen, who have the most rudimentary technology, nevertheless exhibit elaborate religious ceremonials, an extremely complicated kinship organization, and a complex and differentiated language? Why, further, were highly developed cultures, like those of the Maya, the Aztecs, the Peruvians, still using only the simplest handicraft equipment, though they were capable of constructing superbly planned works of engineering and architecture, like the road to Machu Pichu and Machu Pichu itself? And how is it that the Maya, who had neither machines nor draught animals, were not only great artists but masters of abstruse mathematical calculations.

Rooms For Rent Atlanta That Cater To Your Personal Growth Are you looking for just the right room to rent? Maybe you have the resources you need to find it yourself. After all, this is the age of the search engine, and plenty of information is available to anyone who seriously looks for it. There is a wide variety of choice, so you can concentrate only on those homes that might potentially be for you. There are plenty of advantages to occupying rooms for rent atlanta. You save a lot of money paying only part of the expenses you would normally pay for when you have a house of your own. This is because you only have to pay your share of the rent, water, electricity and heat bills. But there are disadvantages to house share too. Conflicts can arise when you live in house that is not yours, especially if you rent a room in a house where the other residents are from a different background than yours. Having a nice place to stay can even help your physical health, and it surely affects your mental health. You may find a place also that comes with furniture already in it. This would allow you to get by with spending less on not only the furniture but the transportation too. Sometimes you can actually save money finding rooms for rent atlanta in the country. This depends on how often you plan to visit the city. If you have a job you can do from home, or if you are retired and collecting benefits, then there is no real reason for you to pay the extra money to live in the city. Of course there are many choices you need to make while you are searching for a room. Some people just do not enjoy living alone. Renting an entire apartment to oneself can, indeed, be a lonely experience. For those who want an easy opportunity to socialize, then, renting a room is a great option. It is little wonder that so many houses on campuses around the country are full of young students renting rooms - its partly for convenience, and definitely partly for the chance to be among others their own age. Renting a room provides the chance to be among one’s peers. There are many more benefits, but perhaps the biggest and best is the advantage of not being locked into something for life. Room rentals can be very appealing, and they can complement the kind of lifestyle you want and deserve. If you want to find the spirit or soul of a city, move right in with its inhabitants. You may benefit socially by taking a couple of classes at the local college. You might try looking for rooms for rent atlanta where there are games, indoor or outdoor. This is a great way to meet people and get started in your new life. Depending on the weather, you might want a pool or access to a gym or tennis courts. Maybe you are attracted to the kind of community that has stunning architecture and green trees and plants. There may be a certain type of street design that appeals to you.

Qafzeh’s algorithms—if implemented properly on a particular architecture of quantum computer—led to a net heat loss from the local universe. A cryo-arithmetic engine was in essence just a computer, running computational cycles. Unlike ordinary computers, however, it got colder the faster it ran.

Ultimately, therefore, the focus of design around these functions and instruments of digital computation represents a shift in the role and nature of the designer: “the tool user (designer) becomes the new toolmaker (software engineer).

Why We Develop Faulty Mental Models of Ourselves as Learners It is very puzzling, in fact, that as lifelong users of our memories and learning capabilities, we do not end up with a more accurate mental model of how we learn, or fail to learn. Why is it, in short, that we are not educated by the “trials and errors of everyday living and learning” (R. A. Bjork, 1999, p. 455)? One consideration is that the functional architecture of how humans forget, remember, and learn is unlike the corresponding processes in man-made devices. Most of us do not, of course, understand the engineering details of how information is stored, added, lost, or overwritten in man-made devices, such as a computer or video recorder, but the functional architecture of such systems is simpler and more understandable than is the complex architecture of human learning and memory. To the extent, for example, that we do think of ourselves as working like such devices, we become prone to assuming that exposing ourselves to information and procedures will lead to storage (i.e., recording) of such information or procedures in our memories—that the information will write itself in one’s memory, so to speak.

In this case, the clicks of users, coupled with the commercial processes that allow paid advertising to be prioritized in search results, mean that representations of women are ranked on a search engine page in ways that underscore women’s historical and contemporary lack of status in society—a direct mapping of old media traditions into new media architecture.

The first age of pyramid building – the half-century from Djoser to Sneferu – had seen an intellectual revolution conducted in architecture and stone images. And part of that took place within this limestone temple, with the dust of pyramid making rising from the desert plain behind them, as some of Sneferu’s courtiers and craftsmen created images personifying the various aspects of the kingdom, from the rhythms of the river and the order of the state to the gods themselves; and all of them identified, drawn and situated as elements of the economic engine, natural and man-made, that would fuel the pharaonic state till its ending.

Cornell’s reputation as a pressure cooker comes from its preprofessional attitude and “we try harder” mentality. Spans 6 colleges—4 private and 3 public. (Tuition varies accordingly.)

The Catholic Church’s policy of blaming women and sex for the ills of the world came to full fruition in the late Middle Ages and on into the Renaissance. At minimum, hundreds of thousands of innocent women and men were hunted down, tortured horribly, reduced to physical, social, and economic wreckage, or burnt at the stake for being “witches”. The Catholic Church, so obsessed with it’s paranoid, irrational, illogical, and superstitious fantasies, deliberately tortured and executed human beings for a period of three hundred years. All this carnage, due to the Church's fear of learning, kept Europe in the throws of abysmal ignorance for a thousand years. What has been lacking in the world since the fall of the ancient world is a logical view of the godhead. To the Greek and Roman mind the gods were utilitarian; that is they offered convenient place to appreciate human archetypes. Sin and redemption from sin had nothing to do with the gods. The classic Greek and Roman gods did not offer recompense in life nor a heavenly afterlife as reward. Rather morality was determined by your service to humanity whether it was in the form of philosophy, science, art, architecture, engineering, leadership, or conquest. In this way humanity could live up to great potential instead of wasting their energy on worship, and false promises For almost a thousand years after the fall of Rome the Catholic Church’s control of society and law guaranteed that woman’s position was degraded to that of a second class citizen, far below the ancient Roman standard. Every literary reference depicts women as inferior, unworthy of inheritance, foolish, lustful and sinful. The Church ordained wife beating and encouraged total obedience to fathers and husbands. Women generally could not own land, join a guild, nor earn money like a man. Despite all this, a series of events unfolded; the crusades, rebirth of classical ideas, the printing press, the Reformation, and the Renaissance, all of which began to move womankind forward. VALENTINES DAY CARDS The Lupercalia festival of the New Year became an orgiastic carnival. A lottery ceremony ensued where men chose their sexual partners by choosing small bits of paper naming each woman present. Later the Christians, trying to incorporate and tame this sexual festival substituted the mythical saint Valentine; and ‘the cards of lust’ evolved into the valentine cards we exchange today.

Note that there is not a focus on eliminating failures. Systems without failures, although robust, become brittle and fragile. When failures occur, it is more likely that the teams responding will be unprepared, and this could dramatically increase the impact of the incident.

The architecture supports a SAML attribute responder that can supply attributes in standardized SAML format not only for Jericho’s EnterSpace Decision Engine (PDP) but also for Jericho’s JAzP module (PEP) as well as for the accessing user.

Performance Tactics on the Road Tactics are generic design principles. To exercise this point, think about the design of the systems of roads and highways where you live. Traffic engineers employ a bunch of design “tricks” to optimize the performance of these complex systems, where performance has a number of measures, such as throughput (how many cars per hour get from the suburbs to the football stadium), average-case latency (how long it takes, on average, to get from your house to downtown), and worst-case latency (how long does it take an emergency vehicle to get you to the hospital). What are these tricks? None other than our good old buddies, tactics. Let’s consider some examples: • Manage event rate. Lights on highway entrance ramps let cars onto the highway only at set intervals, and cars must wait (queue) on the ramp for their turn. • Prioritize events. Ambulances and police, with their lights and sirens going, have higher priority than ordinary citizens; some highways have high-occupancy vehicle (HOV) lanes, giving priority to vehicles with two or more occupants. • Maintain multiple copies. Add traffic lanes to existing roads, or build parallel routes. In addition, there are some tricks that users of the system can employ: • Increase resources. Buy a Ferrari, for example. All other things being equal, the fastest car with a competent driver on an open road will get you to your destination more quickly. • Increase efficiency. Find a new route that is quicker and/or shorter than your current route. • Reduce computational overhead. You can drive closer to the car in front of you, or you can load more people into the same vehicle (that is, carpooling). What is the point of this discussion? To paraphrase Gertrude Stein: performance is performance is performance. Engineers have been analyzing and optimizing systems for centuries, trying to improve their performance, and they have been employing the same design strategies to do so. So you should feel some comfort in knowing that when you try to improve the performance of your computer-based system, you are applying tactics that have been thoroughly “road tested.” —RK

We’re used to thinking of design as creating an intricately engineered setting for the user, for which every act has been accounted. But the contextual meaning of the environment is never permanently established, because context is a function of the active engagement of the user. This means the primary aim of the designer is not to design ways for the artifact to be used but instead to design the artifact to be clearly understood,[66] so the user can recruit it into her full environmental experience in whatever way she needs.

As Fernando Cornago, Senior Director of Platform Engineering, and Markus Rautert, Vice President of Platform Engineering and Architecture, explained their IT department went from being seen as a cost center, with a single vendor providing most of the software (requiring frequent hand-offs) and only a few in-house engineers (doing more managing than engineering), to a product-oriented team organization. Adidas invested 80% of its engineering resources to creating in-house software delivery capabilities via cross-functional

If we accept that the self-similar force (between architecture and team organization) described by Conway is real, then we also need to accept that anyone who makes decisions about the shape and placement of engineering teams is strongly influencing the software systems architecture. There is a logical implication of Conway’s law here, in the words of Ruth Malan: “if we have managers deciding . . . which services will be built, by which teams, we implicitly have managers deciding on the system architecture.”11
