The History of Computing

One of the hardest parts of telling any history, is which innovations are significant enough to warrant mention. Too much, and the history is so vast that it can't be told. Too few, and it's incomplete. Arguably, no history is ever complete. Yet there's a critical path of innovation to get where we are today, and hundreds of smaller innovations that get missed along the way, or are out of scope for this exact story.

Children have probably been placing sand into buckets to make sandcastles since the beginning of time. Bricks have survived from round 7500BC in modern-day Turkey where humans made molds to allow clay to dry and bake in the sun until it formed bricks. Bricks that could be stacked. And it wasn’t long before molds were used for more. Now we can just print a mold on a 3d printer. A mold is simply a block with a hollow cavity that allows putting some material in there. People then allow it to set and pull out a shape. Humanity has known how to do this for more than 6,000 years, initially with lost wax casting with statues surviving from the Indus Valley Civilization, stretching between parts of modern day Pakistan and India. That evolved to allow casting in gold and silver and copper and then flourished in the Bronze Age when stone molds were used to cast axes around 3,000 BCE. The Egyptians used plaster to cast molds of the heads of rulers. So molds and then casting were known throughout the time of the earliest written works and so the beginning of civilization.

The next few thousand years saw humanity learn to pack more into those molds, to replace objects from nature with those we made synthetically, and ultimately molding and casting did its part on the path to industrialization. As we came out of the industrial revolution, the impact of all these technologies gave us more and more options both in terms of free time as humans to think as well as new modes of thinking. And so in 1868 John Wesley Hyatt invented injection molding, patenting the machine in 1872. And we were able to mass produce not just with metal and glass and clay but with synthetics. And more options came but that whole idea of a mold to avoid manual carving and be able to produce replicas stretched back far into the history of humanity.

So here we are on the precipice of yet another world-changing technology becoming ubiquitous. And yet not. 3d printing still feels like a hobbyists journey rather than a mature technology like we see in science fiction shows like Star Trek with their replicators or printing a gun in the Netflix show Lost In Space. In fact the initial idea of 3d printing came from a story called Things Pass By written all the way back in 1945!

I have a love-hate relationship with 3D printing. Some jobs just work out great. Others feel very much like personal computers in the hobbyist era - just hacking away until things work. It’s usually my fault when things go awry. Just as it was when I wanted to print things out on the dot matrix printer on the Apple II. Maybe I fed the paper crooked or didn’t check that there was ink first or sent the print job using the wrong driver. One of the many things that could go wrong.

But those fast prints don’t match with the reality of leveling and cleaning nozzles and waiting for them to heat up and pulling filament out of weird places (how did it get there, exactly)! Or printing 10 add-ons for a printer to make it work the way it probably should have out of the box.

Another area where 3d printing is similar to the early days of the personal computer revolution is that there are a few different types of technology in use today. These include color-jet printing (CJP), direct metal printing (DMP), fused deposition modeling (FDM), Laser Additive Manufacturing (LAM, multi-jet printing (MJP), stereolithography (SLA), selective laser melting (SLM), and selective laser sintering (SLS). Each could be better for a given type of print job to be done. Some forms have flourished while others are either their infancy or have been abandoned like extinct languages.

Language isolates are languages that don’t fit into other families. Many are the last in a branch of a larger language family tree. Others come out of geographically isolated groups. Technology also has isolates. Konrad Zuse built computers in pre-World War II Germany and after that aren’t considered to influence other computers. In other words, every technology seems to have a couple of false starts. Hideo Kodama filed the first patent to 3d print in 1980 - but his method of using UV lights to harden material doesn’t get commercialized.

Another type of 3d printing includes printers that were inkjets that shot metal alloys onto surfaces. Inkjet printing was invented by Ichiro Endo at Canon in the 1950s, supposedly when he left a hot iron on a pen and ink bubbled out. Thus the “Bubble jet” printer. And Jon Vaught at HP was working on the same idea at about the same ti...

Gutenburg shipped the first working printing press around 1450 and typeface was born. Before then most books were hand written, often in blackletter calligraphy. And they were expensive. The next few decades saw Nicolas Jensen develop the Roman typeface, Aldus Manutius and Francesco Griffo create the first italic typeface. This represented a period where people were experimenting with making type that would save space.

The 1700s saw the start of a focus on readability. William Caslon created the Old Style typeface in 1734. John Baskerville developed Transitional typefaces in 1757. And Firmin Didot and Giambattista Bodoni created two typefaces that would become the modern family of Serif. Then slab Serif, which we now call Antique, came in 1815 ushering in an era of experimenting with using type for larger formats, suitable for advertisements in various printed materials. These were necessary as more presses were printing more books and made possible by new levels of precision in the metal-casting.

People started experimenting with various forms of typewriters in the mid-1860s and by the 1920s we got Frederic Goudy, the first real full-time type designer. Before him, it was part of a job. After him, it was a job. And we still use some of the typefaces he crafted, like Copperplate Gothic. And we saw an explosion of new fonts like Times New Roman in 1931.

At the time, most typewriters used typefaces on the end of a metal shaft. Hit a kit, the shaft hammers onto a strip of ink and leaves a letter on the page. Kerning, or the space between characters, and letter placement were often there to reduce the chance that those metal hammers jammed. And replacing a font would have meant replacing tons of precision parts. Then came the IBM Selectric typewriter in 1961. Here we saw precision parts that put all those letters on a ball. Hit a key, the ball rotates and presses the ink onto the paper. And the ball could be replaced. A single document could now have multiple fonts without a ton of work.

Xerox exploded that same year with the Xerox 914, one of the most successful products of all time. Now, we could type amazing documents with multiple fonts in the same document quickly - and photocopy them. And some of the numbers on those fancy documents were being spat out by those fancy computers, with their tubes. But as computers became transistorized heading into the 60s, it was only a matter of time before we put fonts on computer screens.

Here, we initially used bitmaps to render letters onto a screen. By bitmap we mean that a series, or an array of pixels on a screen is a map of bits and where each should be displayed on a screen. We used to call these raster fonts, but the drawback was that to make characters bigger, we needed a whole new map of bits. To go to a bigger screen, we probably needed a whole new map of bits. As people thought about things like bold, underline, italics, guess what - also a new file. But through the 50s, transistor counts weren’t nearly high enough to do something different than bitmaps as they rendered very quickly and you know, displays weren’t very high quality so who could tell the difference anyways.

Whirlwind was the first computer to project real-time graphics on the screen and the characters were simple blocky letters. But as the resolution of screens and the speed of interactivity increased, so did what was possible with drawing glyphs on screens.

Rudolf Hell was a German, experimenting with using cathode ray tubes to project a CRT image onto paper that was photosensitive and thus print using CRT. He designed a simple font called Digital Grotesk, in 1968. It looked good on the CRT and the paper. And so that font would not only be used to digitize typesetting, loosely based on Neuzeit Book.

And we quickly realized bitmaps weren’t efficient to draw fonts to screen and by 1974 moved to outline, or vector, fonts. Here a Bézier curve was drawn onto the screen using an algorithm that created the character, or glyph using an outline and then filling in the space between. These took up less memory and so drew on the screen faster. Those could be defined in an operating system, and were used not only to draw characters but also by some game designers to draw entire screens of information by defining a character as a block and so taking up less memory to do graphics.

These were scalable and by 1979 another German, Peter Karow, used spline algorithms wrote Ikarus, software that allowed a person to draw a shape on a screen and rasterize that. Now we could graphically create fonts that were scalable.

In the meantime, the team at Xerox PARC had been experimenting with different ways to send pages of content to the first laser printers. Bob Sproull and Bill Newman created the Press format for the Star. But this wasn’t incredibly flexible like what Karow would create. John Gaffney who was working with Ivan Sutherland ...

We’ve talked about the history of microchips, transistors, and other chip makers. Today we’re going to talk about Intel in a little more detail.

Intel is short for Integrated Electronics. They were founded in 1968 by Robert Noyce and Gordon Moore. Noyce was an Iowa kid who went off to MIT to get a PhD in physics in 1953. He went off to join the Shockley Semiconductor Lab to join up with William Shockley who’d developed the transistor as a means of bringing a solid-state alternative to vacuum tubes in computers and amplifiers.

Shockley became erratic after he won the Nobel Prize and 8 of the researchers left, now known as the “traitorous eight.” Between them came over 60 companies, including Intel - but first they went on to create a new company called Fairchild Semiconductor where Noyce invented the monolithic integrated circuit in 1959, or a single chip that contains multiple transistors.

After 10 years at Fairchild, Noyce joined up with coworker and fellow traitor Gordon Moore. Moore had gotten his PhD in chemistry from Caltech and had made an observation while at Fairchild that the number of transistors, resistors, diodes, or capacitors in an integrated circuit was doubling every year and so coined Moore’s Law, that it would continue to to do so. They wanted to make semiconductor memory cheaper and more practical.

They needed money to continue their research. Arthur Rock had helped them find a home at Fairchild when they left Shockley and helped them raise $2.5 million in backing in a couple of days.

The first day of the company, Andy Grove joined them from Fairchild. He’d fled the Hungarian revolution in the 50s and gotten a PhD in chemical engineering at the University of California, Berkeley. Then came Leslie Vadász, another Hungarian emigrant. Funding and money coming in from sales allowed them to hire some of the best in the business. People like Ted Hoff , Federico Faggin, and Stan Mazor.

That first year they released 64-bit static random-access memory in the 3101 chip, doubling what was on the market as well as the 3301 read-only memory chip, and the 1101. Then DRAM, or dynamic random-access memory in the 1103 in 1970, which became the bestselling chip within the first couple of years.

Armed with a lineup of chips and an explosion of companies that wanted to buy the chips, they went public within 2 years of being founded. 1971 saw Dov Frohman develop erasable programmable read-only memory, or EPROM, while working on a different problem. This meant they could reprogram chips using ultraviolet light and electricity.

In 1971 they also created the Intel 4004 chip, which was started in 1969 when a calculator manufacturer out of Japan ask them to develop 12 different chips. Instead they made one that could do all of the tasks of the 12, outperforming the ENIAC from 1946 and so the era of the microprocessor was born. And instead of taking up a basement at a university lab, it took up an eight of an inch by a sixth of an inch to hold a whopping 2,300 transistors. The chip didn’t contribute a ton to the bottom line of the company, but they’d built the first true microprocessor, which would eventually be what they were known for.

Instead they were making DRAM chips. But then came the 8008 in 1972, ushering in an 8-bit CPU. The memory chips were being used by other companies developing their own processors but they knew how and the Computer Terminal Corporation was looking to develop what was a trend for a hot minute, called programmable terminals. And given the doubling of speeds those gave way to microcomputers within just a few years.

The Intel 8080 was a 2 MHz chip that became the basis of the Altair 8800, SOL-20, and IMSAI 8080. By then Motorola, Zilog, and MOS Technology were hot on their heals releasing the Z80 and 6802 processors. But Gary Kildall wrote CP/M, one of the first operating systems, initially for the 8080 prior to porting it to other chips.

Sales had been good and Intel had been growing. By 1979 they saw the future was in chips and opened a new office in Haifa, Israiel, where they designed the 8088, which clocked in at 4.77 MHz. IBM chose this chip to be used in the original IBM Personal Computer. IBM was going to use an 8-bit chip, but the team at Microsoft talked them into going with the 16-bit 8088 and thus created the foundation of what would become the Wintel or Intel architecture, or x86, which would dominate the personal computer market for the next 40 years.

One reason IBM trusted Intel is that they had proven to be innovators. They had effectively invented the integrated circuit, then the microprocessor, then coined Moore’s Law, and by 1980 had built a 15,000 person company capable of shipping product in large quantities. They were intentional about culture, looking for openness, distributed decision making, and trading off bureaucracy for figuring out cool stuff.

That IBM decisi...

The Silk Road, or roads more appropriately, has been in use for thousands of years. Horses, jade, gold, and of course silk flowed across the trade routes. As did spices - and knowledge. The term Silk Road was coined by a German geographer named Ferdinand van Richthofen in 1870 to describe a network of routes that was somewhat formalized in the second century that some theorize date back 3000 years, given that silk has been found on Egyptian mummies from that time - or further. The use of silk itself in China in fact dates back perhaps 8,500 years.

Chinese silk has been found in Scythian graves, ancient Germanic graves, and along mountain ranges and waterways around modern India gold and silk flowed between east and west. These gave way to empires along the Carpathian Mountains or Kansu Corridor. There were Assyrian outposts in modern Iran and the Sogdia built cities around modern Samarkand in Uzbekistan, an area that has been inhabited since the 4th millennium BCE. The Sogdians developed trading networks that spanned over 1,500 miles - into ancient China. The road expanded with he Persian Royal Road from the 5th century BCE across Turkey and with the conquests of Alexander the Great in the 300s BCE, the Macedonian Empire pushed into Central Asia into modern Uzbekistan. The satrap Diodotus I claimed independence of one of those areas between the Hindu Kush, Pamirs, and Tengri Tagh mountains, which became known as the Hellenized name Bactria and called the Greco-Bactrian and then Into-Greek Kingdoms by history. Their culture also dates back thousands of years further.

The Bactrians became powerful enough to push into the Indus Valley, west along the Caspian Sea, and north to the Syr Darya river, known as the Jaxartes at the time and to the Aral Sea. They also pushed south into modern Pakistan and Afghanistan, and east to modern Kyrgyzstan. To cross the Silk Road was to cross through Bactria, and they were considered a Greek empire in the east. The Han Chinese called them Daxia in the third century BCE. They grew so wealthy from the trade that they became the target of conquest by neighboring peoples once the thirst for silk could not be unquenched in the Roman Empire. The Romans consumed so much silk that silver reserves were worn thin and they regulated how silk could be used - something some of the Muslim’s would do over the next generations.

Meanwhile, the Chinese hadn’t known where their silk was destined, but had been astute enough to limit who knew how silk was produced. The Chinese general Pan Chao in the first century AD and attempted to make contact with the Roman’s only to be thwarted by Parthians, who acted as the middlemen on many a trade route. It wasn’t until the Romans pushed East enough to control the Persian Gulf that an envoy was sent by Marcus Aurelius that made direct contact with China in 166 AD and from there, spread throughout the kingdom. Justinian even sent monks to bring home silkworm eggs but they were never able to reproduce silk, in part because they didn’t have mulberry trees. Yet, the west had perpetrated industrial espionage on the east, a practice that would be repeated in 1712 when a Jesuit priest found how the Chinese created porcelain.

The Silk Road was a place where great fortunes could be found or lost. The Dread Pirate Roberts was a character from a movie called the Princess Bride, who had left home to make his fortune, so he could spend his life with his love, Buttercup. The Silk Road had made many a fortune, so Ross Ulbricht used that name on a site he created called the Silk Road, along with Frosty and Attoid. He’d gotten his Bachelors at the University of Texas and Masters at Penn State University before he got the idea to start a website he called the Silk Road in 2011. Most people connected to the site via ToR and paid for items in bitcoins. After he graduated from Penn State, he’d started a couple of companies that didn’t do that well. Given the success of Amazon, he and a friend started a site to sell used books, but Ulbricht realized it was more profitable to be the middle man, as the Parthians had thousands of years earlier. The new site would be Underground Brokers and later changed to The Silk Road. Cryptocurrencies allowed for anonymous transactions. He got some help from others, including two that went by the pseudonyms Smedley (later suspected to be Mike Wattier) and Variety Jones (later suspected to be Thomas Clark).

They started to facilitate transactions in 2011. Business was good almost from the beginning. Then Gawker published an article about the site and more and more attention was paid to what was sold through this new darknet portal. The United States Department of Justice and other law enforcement agencies got involved. When bitcoins traded at less than $80 each, the United States Drug Enforcement Agency (DEA) seized 11 bitcoins, but couldn’t take the site down for good. It was actually an IRS investi...

Once upon a time, the right to copy text wasn’t really necessary. If one had a book, one could copy the contents of the book by hiring scribes to labor away at the process and books were expensive. Then came the printing press. Now, the printer of a work would put a book out and another printer could set their press up to reproduce the same text. More people learned to read and information flowed from the presses at the fastest pace in history.

The printing press spread from Gutenberg’s workshop in the 1440s throughout Germany and then to the rest of Europe and appearing in England when William Caxton built the first press there in 1476. It was a time of great change, causing England to retreat into protectionism, and Henry VIII tried to restrict what could be printed in the 1500s. But Parliament needed to legislate further.

England was first to establish copyright when Parliament passed the Licensing of the Press Act in 1662, which regulated what could be printed. This was more to prevent printing scandalous materials and basically gave a monopoly to The Stationers’ Company to register, print, copy, and publish books. They could enter another printer and destroy their presses. That went on for a few decades until the act was allowed to lapse in 1694 but began the 350 year journey of refining what copyright and censorship means to a modern society.

The next big step came in England when the Statute of Anne was passed in 1710. It was named for the reigning last Queen of the House of Stuart. While previously a publisher could appeal to have a work censored by others because the publisher had created it, this statute took a page out of the patent laws and granted a right of protection against copying a work for 14 years. Reading through the law and further amendments it is clear that lawmakers were thinking far more deeply about the balance between protecting the license holder of a work and how to get more books to more people. They’d clearly become less protectionist and more concerned about a literate society.

There are examples in history of granting exclusive rights to an invention from the Greeks to the Romans to Papal Bulls. These granted land titles, various rights, or a status to people. Edward the Confessor started the process of establishing the Close Rolls in England in the 1050s, where a central copy of all those granted was kept. But they could also be used to grant a monopoly, with the first that’s been found being granted by Edward III to John Kempe of Flanders as a means of helping the cloth industry in England to flourish.

Still, this wasn’t exactly an exclusive right but instead a right to emigrate. And the letters were personal and so letters patent evolved to royal grants, which Queen Elizabeth was providing in the late 1500s. That emerged out of the need for patent laws proven by Venicians in the late 1400s, when they started granting exclusive rights by law to inventions for 10 years. King Henry II of France established a royal patent system in France and over time the French Academy of Sciences was put in charge of patent right review.

English law evolved and perpetual patents granted by monarchs were stifling progress. Monarchs might grant patents to raise money and so allow a specific industry to turn into a monopoly to raise funds for the royal family. James I was forced to revoke the previous patents, but a system was needed. And so the patent system was more formalized and those for inventions got limited to 14 years when the Statue of Monopolies was passed in England in 1624. The evolution over the next few decades is when we started seeing drawings added to patent requests and sometimes even required. We saw forks in industries and so the addition of medical patents, and an explosion in various types of patents requested.

They weren’t just in England. The mid-1600s saw the British Colonies issuing their own patents. Patent law was evolving outside of England as well. The French system was becoming larger with more discoveries. By 1729 there were digests of patents being printed in Paris and we still keep open listings of them so they’re easily proven in court. Given the maturation of the Age of Enlightenment, that clashed with the financial protectionism of patent laws and intellectual property as a concept emerged but borrowed from the patent institutions bringing us right back to the Statute of Anne, which established the modern Copyright system. That and the Statue of Monopolies is where the British Empire established the modern copyright and patent systems respectively, which we use globally today. Apparently they were worth keeping throughout the Age of Revolution, mostly probably because they’d long been removed from the monarchal control and handed to various public institutions.

The American Revolution came and went. The French Revolution came and went. The Latin American wars of independence, revolutio...
