Self-Driving Software: Why We Need E Pluribus Unum

Today, numerous large and small companies around the world are working diligently on perfecting their company’s self-driving software. All the large traditional automobile companies are included as well as large technology firms such as Google, Intel and Microsoft, and even Uber. These companies are working in true twentieth-century capitalist fashion: they’re doing it all independently and secretly. This approach leads to sub-optimal technology and foreseeable tragedies.

Self-Driving Vehicles Use Artificial Intelligence (AI)

Programming a self-driving vehicle (SDV) by traditional software-development methods is so fraught with complexity that no one, to my knowledge, is attempting. So scrap that idea. Instead, developers have flocked to artificial intelligence, a red-hot technology idea built on rather old ideas about neural networks.

There’s a lot to AI technology beyond the scope of this blog. A quick Internet search will get you started on a deep dive. For today, let’s sketch a common approach to AI application development:

  • First, an AI rules-based model is fed real-world scenarios, rules, and practical knowledge. For example, “turning left into oncoming traffic (in the USA but not the UK) is illegal and hazardous and will likely result in a crash. Don’t do that.” This first phase is the AI Learning Phase.
  • Second, the neural network created in the learning phase is executed in a vehicle, often on a specialized chip, graphics processing unit (GPU) or multi-processor. This is the Execution Phase.
  • Third, the execution unit records real-world observations while driving, eventually feeding them back into the learning model.

The Problem of Many

Here’s the rub. Every SDV developer is on its own, creating a proprietary AI model with its own set of learning criteria. Each AI model is only as good as the data fed into its learning engine.

No single company is likely to encounter or imagine all of the third standard-deviation, Black Swan events that can and will lead to vehicle tragedies and loss of life. Why should Tesla and the state of Florida be the only beneficiaries of the lessons from a particular fatal crash? The industry should learn from the experience too. That’s how society progresses.

Cue the class-action trial lawyers.

E Pluribus Unum

E Pluribus Unum is Latin for “out of many, one”. (Yes, it’s the motto of the United States). My proposal is simple:

  • The federal government should insist that all self-driving vehicles use an AI execution unit that is trained in its learning phase with an open-source database of events, scenarios, and real-world feedback. Out of many AI training models, one model.
  • The Feds preempt state regulation of core AI development and operation
  • Vehicles that use the federalized learning database for training receive limited class-action immunity, just like we now do with immunization drugs.
  • The Feds charge fees to the auto industry that cover the costs of the program.


From a social standpoint, there’s no good reason for wild-west capitalism over proprietary AI learning engines that lead to avoidable crashes and accidents. With one, common AI learning database, all SDVs will get smarter, faster because they are benefiting from the collective experience of the entire industry. By allowing and encouraging innovation in AI execution engines, the industry will focus on areas that impact better-faster-cheaper-smaller products and not in avoiding human-risk situations. Performance benchmarks are a well-understood concept.

Philosophically, I don’t turn first to government regulation. But air traffic control, railroads, and numerous aspects of medical areas are regulated without controversy. Vehicle AI is ripe for regulation before production vehicles are produced by the millions over the next decade.

Buying a PC for Your Third-World Adventure

A reader of this blog asked “What PC should I buy that can survive the erratic electricity of a third-world residency?” The answer, of course, is “It depends how much you want to spend.” But having reliable computing in a less-developed setting need not break the bank.


You’re an average, modern computer user with professional (i.e., office), social, and personal computing needs preparing to reside outside a first-world power grid. You could be in the mountains of Columbia or Colorado, or, like me, at the end of a one-kilometer driveway. You need to be able to use your PC at any time, but not necessarily all the time. You have a budget.

My previous stories on this subject are here. Your problem is spotty power that can come and go at any moment, day or night, and be off for hours. Your collateral problem is poor power with spikes, low and high voltage, surges, and intermittent on/off cycles. These can and will destroy the unprotected PC power supply in short order.


The strategy is to put as much inexpensive stored electricity (i.e., batteries) in front of the computer’s power supply as practical. Duh! The easiest implementation is to use a laptop, which comes with a built-in battery. Modern laptops have hours of self-contained power while you wait for the power grid, backup generator, or tomorrow’s sun to renew your power supply.

Still easy but more expensive choices are a desktop all-in-one (such as an Apple iMac) or a regular desktop. In both the desktop cases cases, you’ll want an uninterruptible power supply (UPS) which stores AC grid power in a battery and delivers it to your electronic devices.

With those assumptions and strategy in mind, here is a prioritized list of what to buy and why to buy it:

The Basics

  • A laptop. Commercial grade (e.g., Dell XPS) has higher build quality than consumer grade (e.g., Dell Inspiron). You get what you pay for. Consider: 17″ screen-size as desktop replacement; SSD for reliability and speed. Your choice: Windows, Mac, even Chromebook.
  • A high-quality surge protector to filter as much electrical grief as possible. Mandatory unless you use a UPS.
  • A bigger and/or backup laptop battery. Greater off-grid time. More efficient than a UPS. Lowest cost when bought bundled with a new laptop.

The Upgrades

  • A powerful UPS, where power is measured in volt-amps. Over 1,000VA is better. Below 500VA is probably pointless with a laptop. The UPS has receptacles for other electrical necessities, so it becomes your electrical hub. Also, all UPS systems have power quality circuitry so your PC will always get clean power. Also, PC applications and a USB connection to the UPS can automatically and safely shut any PC down before the UPS itself exhausts its batteries.
  • A portable hard drive storage device to back up your PC. If this were me, it would rank in the Basics as a “must have”. The portable hard drives require no electrical power beyond a USB cable. With electricity (from your UPS), there are faster/greater capacity options.
  • A USB 3.0 Hub for greater I/O connectivity. Your laptop or all-in-one will never have enough USB ports for the printers, backup storage, Bluetooth speakers, and mobile devices that need charging. Your choices are four or seven ports. Go with the powered seven-port hub. After all, everyone in your house (office) will want to leech off your clean power. Plan accordingly.

The Options

Here’s where the budget goes out the window, but your level of electricity paranoia is nobody else’s business:

  • A secondary monitor scales your laptop’s screen to desktop size or becomes a second screen with more real estate.
  • Backup generator sized to your home electricity load. Best purchased locally as you will require service eventually. Requires (clean) gasoline.
  • Solar power generator requires solar panels, an AC inverter, and distribution hub. It can have its own battery for storage or use the UPS already in our specs. The money problem is a 300-400 watt solar installation can easily cost as much or more than our laptop computing device.
  • The ultimate upgrade for this scenario is a Ford C-Max Energi plug-in hybrid car with internal 7.4 kWh batteries, 2 AC power outlets, USB charging, and 12-volt power. You can also drive it. $31,770 and up.

Is a Tablet an Alternative?

A tablet or a laptop/tablet (i.e., a two-in-one) is worth considering. Portable, mobile, self-contained cellular network option. Some have a desktop operating system. The keyboard and mouse can use easily rechargeable AA batteries. Device operating life often exceeds eight hours. Rechargeable from a small solar panel. Connects to Bluetooth peripherals and to a video monitor/TV via an HDMI cable.

Minimalist computing dramatically simplifies backup power requirements.

Consolidated electronics such as a tablet connected to the LCD monitor also used as a TV makes planning easier and redundancy less necessary.

The Network

Getting on the Internet has its own set of problems and costs. You’ll need local knowledge to make cost-effective decisions.

Assuming a controllable data budget, the easiest Internet on-ramp is to use your smartphone as a hotspot and connect your laptop via Bluetooth. You won’t find unlimited data plans in the third world, so this approach needs careful usage-based planning.

A conventional desktop or laptop setup will require a network access device(s) to the cable, wireless broadband, or satellite network. Plan to power-protect these devices too by plugging them into your UPS. However, that limits PC placement to being close to the network access point.

Buying a PC Online: a 2015 Saga of Customer-Service Inefficiency

In this open letter to Michael Dell, CEO at, we relate the saga of a friend I’ll call Russ and his journey to buying a replacement PC online.

Plan A: Lenovo Chokes
Russ had an old, Lenovo one-core AMD workhorse desktop upgraded to Windows 7 awhile back. The box got slower than molasses. After all the usual speed-up remedies failed, Russ decided to buy a new desktop. We consulted as I do for (too) many friends and decided on a modest machine with a solid-state disk. Russ went online and configured-to-order in early November. Problem solved ….

But not quite. Lenovo quoted a delivery date, and when December rolled around, Russ queried when was his new PC going to be built and shipped. The answer was “We don’t know, but hold tight.” Russ replied, “Not good. Cancel the unfulfilled order.” Lenovo said, and I paraphrase, “You can’t cancel the order because we have released it to our manufacturing supply chain in China. It will arrive when it is built and shipped.” Russ called American Express and put the charge on indefinite hold in case it actually arrives some day.

Moral: 1. Don’t take an order you cannot fulfill. 2. Don’t leave a customer hanging.

Plan B: Dell Gets to Bat
With a little coaching, Russ found what he wanted at an Inspiron desktop without an SSD but with a decent Intel “Haswell” Core i3 processor, 4GB of memory, and a 1TB hard drive running Windows 10. Price was US$449 with free shipping. The clincher was same-day shipping.

The Unboxing: a Moment of Silence and Sadness
The new PC arrived in four days. I came over Sunday morning with assorted tech bits so we could hook up the new Inspiron and to run Microsoft’s sweet Windows Migration Tool to get it into production. Popped open the chassis, added 4GB of memory, closed the chassis, connected the cables and hit the power-on switch.

Nothing happened. Nada. The PC would not power on in spite of trying different electrical sockets and AC cables. It was a 2015 PC Dead on Arrival.

We were sad but not completely surprised as these things happen — presumably very rarely because of the Dell costs to swap a DOA machine. So, we called Dell Tech Support to get started.

Tech Support: Call Triage
It took eleven minutes to wait on hold, enter the PC service tag, explain to the tech we had a DOA machine that we wanted to swap. The information requested included the service tag, serial number, name and address, and other bits of information — all of which is already stored in Dell’s order entry system but was nevertheless verified and keystroked again into the service system.

We made it through triage and onto tech support’s call resolution team.

Tech Support: Call Resolution Team
This call took eighteen minutes, with most of the time spent on hold at the end waiting to be transferred to Sales. The business-process problem with the call resolution phase is simple: the department is a separate information silo from call triage, and no call or problem data is shared.

Russ had to literally spell out the same answers to information questions including the service tag, serial number, order name and address, and other bits of information that had already been amassed at order-taking and call-triage. Besides boring the customer to tears, the process is a poor use of tech support labor.

Reassuring us that the four-day-old PC was still under warranty, call resolution rang off to run down the DOA return process. After seven minutes, we were told that Sales handled returns and “please hold while I transfer you to that department.”

Sales Support: Waiting for Godot
And we waited some more with occasional call-tree clicks that eventually ended with a recorded message saying “Sales is closed on Sundays, so call us during business hours tomorrow.”

Customer time to non-resolution of a DOA problem: more than 30 minutes. Russ was pissed. I went home to lunch.

Luncheon Epiphany
I often skim the Sunday newspaper advertising inserts to keep track of technology mainstream deals and product positioning. For example, Intel’s Broadwell and Skylake 14nm processors only recently started being featured in PCs at BestBuy, and are still not being advertised at Wal-Mart, Target, Staples, or OfficeMax.

That’s how I found the Staples ad for a Dell Inspiron 1300 desktop with a Intel “Haswell” Core i3 processor, 8GB of memory, and a 1TB hard drive running Windows 7 Pro. Price $300, marked down from $580, and $150 less than’s almost identical DOA PC.

I telephoned Russ, he picked the PC up that afternoon, and the migration was well underway on Monday morning. The DOA machine goes back to the Dell factory tomorrow.

Dear Michael,
I silently applauded your taking Dell private because the mature PC industry in a slowing global economy does not need a quarterly spotlight on top of all its other challenges. I expected lots of value could be wrung out of the business with greater efficiencies and focus on key business processes. Dell has been a build-to-order online specialist for, like, thirty years.

So, I was disappointed that Dell’s DOA process involved so many steps across organizational and information silos that cry out for a rethink. I hope you’ll take this missive to heart. You know what to do about this.

No, It’s Not Just Dell and Lenovo …
HP has no laurels to sit on. Even Apple has disappointed me on more than one occasion. As this saga illustrates, the PC industry can do better on customer satisfaction.

The future of personal information technology is not one-size-fits all. It’s “buy what you need and want”. That’s going to take a holistic approach to online sales and service. You would have thought that would be old-hat going into 2016, but apparently not.
