Ethiopia has chosen to greatly increase its use of technology and its standard of living.
By Daniel Alman (aka Dan from Squirrel Hill)
June 16, 2024
Ethiopia has chosen to greatly increase its use of technology and its standard of living.
The Ethiopia of today is absolutely nothing like the Ethiopia that people my age (I’m 53) saw on TV when we were growing up.
Back then, the news blamed Ethiopia’s famines on drought.
Now, this video says that during several recent droughts, there was no famine, and that was because of the choices that they made regarding irrigation, modern farming methods, and other advances in technology.
The same video also shows Ethiopians manufacturing clothing for export to rich countries, and they pointed out that Ethiopia is currently at the approximate level of development than China was at one generation ago.
I totally support these tremendous improvements.
I support using modern technology to give every person on earth a first world standard of living. The Asian tiger countries went from third world to first world in a very short period of time. Now Haiti is starting to do the same thing.

An experiment in Haiti is making once-arid lands fertile, and poor farmers into money-makers
By Jacqueline Charles
November 24, 2023




At first sight, the nearly four acres of farmland in this rural hamlet in northeast Haiti resembles more of a desert than a thriving agricultural experiment. The soil is brown and barren, battered by a lack of water and neglect.
But walk further inland and the seemingly lifeless terrain soon turns green: Cabbages and pumpkins rise out of the ground, papayas hang from trees and workers plant rows of hot peppers in the freshly plowed dirt as a generator hisses in the background.
A year ago, such a lush landscape was unimaginable for Fransik Monchèr, a farmer and father of seven who couldn’t even grow fiery habanero peppers because they quickly died.
All that changed the day a group of entrepreneurs decided to take a gamble to launch a socioeconomic experiment with the goal of answering a simple, but daunting question: What if a Haitian farmer, like Monchèr, had everything he needed to be a successful grower?
“That farmer who has the land, how do you get him to upgrade his way of production — and how do we recuperate that cost?” said Maxwell Marcelin, one of the entrepreneurs.
The quest for the answers has birthed an unusual partnership among four Port-au-Prince-based friends and entrepreneurs, and local farmers and agronomists in northern Haiti. Together, they are pushing locally grown peppers and sweet potatoes while also aiding farmers like Monchèr in transforming their sun-scorched land, restoring hope in the only livelihood they’ve known: agriculture.
Though 75% of Haiti’s population lives in rural areas, the country can’t feed itself. Nearly half of the population, 4.9 million people, are experiencing acute hunger, according to the United Nations. The blame, the U.N. says, can be placed on a number of factors, including poor irrigation systems, lack of capital, political instability and the intensifying gang violence that has spread beyond the capital of Port-au-Prince to rural areas.
In areas where gangs are not occupying farmland or distribution routes, small-scale farmers are fighting to grow crops with limited or no government support. Crops fail due to increasingly frequent and severe droughts and tropical storms, and higher-than-average temperatures.
None of it makes for a hopeful scenario where agriculture can once more become the driving economic force in the countryside.
“Everybody is locked into the idea that it can’t be done,” said Geoffrey Handal, the accounting and logistics expert in the friends’ group, who challenges such pessimism. “We have all of the qualified agronomists, we have all of the techniques needed, we have all of the land, we have all of the water, we have everything.”
While Haiti’s capital is overrun by gangs, in the north entrepreneurs and farmers are trying to focus on its economic potential. Peppers like these growing in a field in Paulette, Haiti are being grown for both the local and export markets.
‘Total despair’
When Marcelin first arrived at Monchèr’s farm in Limonade, the northeast city that is part of the Marihaboux Plain, he believed, like the farmer, that the land was unworkable.
“It was total despair,” Marcelin said, as a group of workers dig a hole on a dirt mound to plant habanero pepper trees. “He said every time he tried to plant, there was no rain and he would lose his harvest.”
Refusing to accept that the expansive plot was a wasteland, Marcelin and Handal began to think about how they could help. Monchèr not only needed seeds, but also financing. But most importantly, he needed a steady supply of water so he wouldn’t have to depend on rains.
“That’s the basis of agriculture. Otherwise it’s like you’re playing the lottery” waiting for rain, Marcelin said.
Farmers in Haiti have always struggled to make a living off their crops. But with help from a group of fellow Haitians, they are hoping to see their fortunes turn.
In Haiti, crops failed not just because of too little or too much rainfall, but also due to a lack of access to irrigation, even when water is available.
Just across the border 45 minutes away in the Dominican Republic farmers are successful, Marcelin said, so the issue is not the availability of water.
“The only thing is there is no investment on our side of the border to bring the water to the producers,” he said.
Armed with a study showing that there was indeed water under Monchèr’s arid land, the group sprang into action. Magalie Dresse, a well-known designer who works with women artisans, helped with financing. Handal, who is also experimenting with producing a bank of high-quality seedlings, provided the seeds. And Marcelin crunched the numbers. With a background in management economics, he wanted to show Monchèr that he could have a successful harvest and rely on it for income to feed his family.
“We provided him with a well, a submersible pump, a generator —a propane one because there is no gas,” Marcelin said. ”He has the support of one of our agronomists to help him on what to do and what not to do. We plowed his field.”
The contributions have not gone unnoticed. Since January, Monchèr has grown more than 2,000 pounds of habanero peppers in addition to other fruits and vegetables.
‘“They backed me up,” he said, flashing a smile and standing upright in his field. “I could not have accomplished this on my own. I could not have dug a well because I don’t have the means to do that.”
Whereas before he saw despair, he now sees hope.
“My children are starting to eat and I am beginning to make some money. If they tell me they are hungry, I can come here, grab two or three papayas and sell them to find money to buy food,” Monchèr said.
The group’s initial investment of about 480,000 gourdes — about $3,600 — is expected to bring Monchèr about $7,000 in sales, which he will make from selling his habanero peppers to AGRILOG/Ets JB Vital, S.A., the company that Marcelin and Handal use to export peppers to Miami.
A group of young entrepreneurs from Port-au-Prince is helping farmers in northern Haiti grow peppers. This variety, known as “Piman Bouk,” is among the peppers being developed in Paulette, Haiti.
“This is someone we’ve taken out of poverty when we gave him this opportunity,” Marcelin said.
“Because we invested in Fransik,” he adds, walking through the papaya trees, “we’ve created an oasis.”
From coffee to sweet potatoes
Growing up in a poverty-stricken Haiti as a member of a well-off family, Handal knew he was blessed, a feeling he’s wanted to share with others.
“I’ve always felt like every Haitian should have it and we should show the world this is how we live,” he said.
For 200 years, the Handal family exported coffee, once among the island’s most lucrative cash crops. But deforestation, natural disasters and the increasing need for coffee to be grown at higher elevations due to warming temperatures led to a rapid decline in coffee production. In 2008, Handal said the family was shipping 33 cargo containers of coffee beans each season.
A year later, before the devastating 2010 earthquake further decimated production, the family shipped only two containers “because we couldn’t find any coffee.”
Handel said that an investigation into the demise of Haiti’s coffee market led him to conclude that the family needed to invest in agricultural production. But more than a decade went by before he revisited the idea of exports, spending most of the time working in the family’s shipping business in Port-au-Prince.
“I realized the only two things we could export here would be, first of all, textiles and second, agriculture,” he said. He decided on the agriculture route as a way to boost his export volume. “It was purely a logistic play to see what could I do to get containers full of agriculture products out of Haiti.”
Then he met Marcelin, who pitched him on growing peppers and sweet potatoes, and helping farmers boost their harvest.
“The Dominican Republic is the same size, same economy as Haiti and there is no reason why we can’t reach that level of GDP,” Handal said. “If we do this right, if we invest properly in Haiti in 20 years, we can have 10% GDP growth every year. With that measure, this is how billionaires get made. This is how you create a real economy.”
Marcelin said he became interested in agriculture through the work of his wife, Kalinda Magloire. She is the founder of a clean cooking social enterprise known as SWITCH, which encourages Haitians to move away from charcoal in favor of propane.
One of the effects of Haiti’s declining agricultural sector is that when farmers can’t cultivate their land, they turn to cutting their trees down for charcoal production, which gives them about $400 every two years. For farmers to stop cutting trees to survive, said Marcelin, they need a path to production to get replace that revenue.
Cutting down the trees is “the easiest choice today because he doesn’t have money to invest, so he just lets the trees grow and then every two years, he sells them,” he said. “But if he had the financing, the know-how and access to market, he would have an alternative.
“When we were presenting clean cooking as an alternative, the question we were always presented with was, ‘What about the farmer who lives off charcoal?’ ” Marcelin adds. “This is why we started thinking about agriculture.”
Bringing back the Scotch bonnet, saving the Bouk
About 17 miles to the east of Limonade along National Highway 6 in the rural community of Paulette is the for-profit side of Marcelin and Handal’s vision. Together with the Peasant Movement for the Development of Paulette they are growing sweet potato and several varieties of pepper, including the high-in-demand “Piman Bouk,” whose first shipment arrived in Miami in April.
Despite the demand for Bouk, it is hard to find, said Handal, who has built a nursery to provide high quality pepper seeds.
“Today, even if a farmer wants to go plant Bouk, he won’t find quality seeds to do it,” Handal said.
The entrepreneurs also want to bring back production of the Caribbean Scotch bonnet, a variety of chili pepper. According to local lore, the Scotch bonnet, popular in Jamaica, was bountiful around Cap-Haïtien before the Haitian revolution but soon disappeared after Haiti won its independence from France in 1804.
The two are also working on exporting sweet potato, which for now is being sold on the local market as they continue to improve the yield for export to Europe with the help of agronomists from Honduras, who have expertise in growing the vegetable.
Geoffrey Handal is among four friends from Port-au-Prince, Haiti who have come together to launch a socioeconomic lab focused on helping farmers in northern Haiti access expertise and new techniques to grow crops.
To make the agricultural project work, the duo invested in a drip irrigation system, similar to what’s used in the Dominican Republic, and fertilizer. They also brought onboard interns from the nearby University of Limonade to assist and to learn.
The financial model, which Handal came up with, calls for the Paulette farmers to get 30% of sales.
“At the end of the day, when you look at the investment, it comes up to 50-50 in terms of profits,” Marcelin said. “In Paulette, it’s a Fransik Monchèr magnified. We created jobs but the profit sharing is for the whole organization…. Everyone who is in the ecosystem is making money.”
Handal also sees another important result.
“For me as long as the community is involved, that’s all you need,” he said.
The two also focus on finding creative ways to get around problems. After some of the habaneros and Piman Bouk ripened before they could be shipped out, Marcelin and Handal decided to go into the pepper sauce business.
With their next harvest less than 30 days away, they are hoping the sweet potatoes will be ready so they can be shipped out. If not, they will just continue to sell it locally.
The effort is “a bet that this country will not die, which is a bit of a leap of faith these days. But if it’s not going to die, it’s going to grow at some point,” Handal said. “And that’s why we invest.”

Original video: “Tesla S will not charge in the cold. Stranded on Christmas Eve!”
https://www.tiktok.com/@domnatishow/video/7180839253562199338
“UPDATE: I received several calls today from @Tesla Motors . They have been very accommodating so far, and are towing my car 2 hours away to Richmond to the service center at their own expense. Also, they delivered a loaner in the meantime.”
https://www.tiktok.com/@domnatishow/video/7181594117112122666
“UPDATE: Shocking interaction with Tesla service! They sent an estimate of nearly $2,000 and said my battery heater is broken. The notification on my screen said the battery is heating which was not true and their response regarding this false notification was very disappointing.”
https://www.tiktok.com/@domnatishow/video/7182837104857140522
Domenick Nati from Virginia, for instance, tried to charge his Tesla Model S ahead of Christmas but encountered some problems.
“I tried to charge it at my house, it won’t let me. So there’s no way to charge this battery or let it warm up in the cold,” Nati said in a TikTok video.
He then took the car to a Tesla Supercharger station and plugged it in but it failed to charge again.
The vehicle showed a message that the battery was heating and the car had a range of 19 miles at 1:11 pm.
“3:03, almost two hours later — battery is heating, 19 miles,” Nati read from the vehicle display with frustration later that day.
The temperature was reportedly around 19°F, or -7°C, at the time.
Nati’s video — titled “Tesla S will not charge in the cold. Stranded on Christmas Eve!” — has now amassed roughly 113,000 likes on TikTok.
I asked ChatGPT: “Does the transporter on Star Trek kill every person who uses it, and then manufacture an exact duplicate?”
I asked ChatGPT: “Does the transporter on Star Trek kill every person who uses it, and then manufacture an exact duplicate?”
This is the answer that it gave:
“No, the transporter on Star Trek does not kill every person who uses it, and then manufacture an exact duplicate. The transporter is a device used to teleport people and objects from one location to another. It works by breaking down the molecular structure of the subject and then reassembling it at the destination. The goal of the transporter is to safely transport the subject from one place to another, not to kill them and create a duplicate.”
“In the Star Trek franchise, the transporter is generally considered a safe and reliable technology, and it is widely used for transportation purposes. While there have been instances in which the transporter has malfunctioned or been used in unusual ways, leading to strange and sometimes dangerous consequences, these instances are few and far between.”
“It is important to remember that the Star Trek franchise is a work of fiction, and the depiction of the transporter and its effects on people and objects is not meant to be taken as a scientific explanation of how teleportation would actually work in the real world. The transporter is a science fiction device that is used to drive the story and create exciting and imaginative scenarios for the characters.”

There’s a “smart” phone app that tells you when your jar of peanut butter is empty. How dumb can people be?
By Daniel Alman (aka Dan from Squirrel Hill)
August 29, 2022
I’ve never actually owned a “smart” phone. And I guess this is one reason why.
There is now an app that tells your “smart” phone when your jar of peanut better is empty.
This article from the Pittsburgh Tribune-Review is from four years ago, but I just found about it now. It says:
Even though no one can see you eating peanut butter off a spoon in the middle of the night, the jar’s label might soon be “watching.”
Adrich, a Pittsburgh company that designs smart labels that could alert customers when they’re running low on their favorite products, just signed its first major deal to slap their innovation on products bound for consumers’ homes.
The labels will be able to track when and how much of a product people use. Sensors embedded in the labels can detect movement and also determine how much of a product remains, Aji said. Adrich then uses a proprietary algorithm to make sense of the data.
For example, during tests in which labels were on jars of peanut butter, Adrich found that people snacked on peanut butter at all hours of the day.
Companies can send coupons or other promotions when they sense a customer is about to run out of a product. Customers can learn when they should restock.
The labels — “almost like a mini-computer,” Aji said — contain a battery and sensors but are nearly as thin as a regular label. The label connects to a user’s smartphone through Bluetooth.
I’m 51 years old. I’ve been eating peanut butter ever since I was a child. And I’ve never, ever had trouble figuring out if the jar was empty.
And even when the jar is empty, well, I plan in advance, so I always have an extra jar (or a few, actually) because I always stock up on all of the non-perishable foods that I eat on a regular basis. That’s why homes have kitchen cabinets, shelves, and pantry closets. I have actually never, ever run out of peanut butter, soap, or toothpaste, because I always know that I’m always going to be using those things, so I always keep extra in my home.
Is there anyone who is so dumb that they need an app to tell them when their jar of peanut butter is empty?
How 1,500 Nuclear-Powered Water Desalination Plants Could Save The World From Desertification
How 1,500 Nuclear-Powered Water Desalination Plants Could Save The World From Desertification
By James Conca
July 14, 2019
About 20% of the world’s population has no access to safe drinking water, and this number will increase as the population continues to grow and global freshwater sources continue to decline. The worst-affected areas are the arid and semiarid regions of Asia, the Middle East and North Africa.
UNESCO has reported that the freshwater shortfall worldwide will rise to 500 trillion gallons/yr by 2025. They expect water wars to break out in the near-future. The World Economic Forum says that shortage of fresh water may be the primary global threat in the next decade.
But 500 trillion gallons/year only requires about 1,500 seawater desalination plants like the ones being built in California and Saudi Arabia. At a billion dollars a pop, that’s a lot cheaper than war and starvation.
Unfortunately, we presently desalinate only 10 trillion gallons/year worldwide.
As reported in the Tri-City Herald and NYTimes, stock exchange mutual funds have even formed surrounding water scarcity and have done quite well, like the AllianzGI Global Water Fund. This fund has averaged almost 10% since 2010 compared to under 6% for its average peer fund. These companies mainly deliver, test and clean drinking water.
In California, the MegaDrought, that ended in 2017 ran for five years, severely straining water supplies, agricultural needs and wildlife. It clarified the need to build new desalination plants like every other modern arid population in the world. Most of Abu Dhabi’s gas-fired power plants provide electricity to their huge desalination plants that deliver over a billion gallons of drinking water a day, at about 40¢/gallon. And it tastes good, too, I’ve tried it.
California needs 30 large desalination plants to deal with future megadroughts. They did recently build one in Carlsbad, but it’s not nearly enough.
Desalination technologies are capable of treating water from a wide variety of sources, including brackish groundwater, surface water, seawater, and domestic and industrial wastewater. While the wastewater from desalination is itself problematic, MIT has developed a process to turn it into useful products.
The two main types of desalination are:
– thermal desalination (using heat energy to separate the distillate from high salinity water), represented by Multiple Effect Distillation (MED), Multi-Stage Flash distillation (MSF) and Mechanical Vapor Compression (MVC), the latter primarily used to desalinate highly salty waters and industrial wastewater for industrial use, not necessarily for drinking.
– reverse osmosis (RO) membrane separation, which uses a membrane barrier and pumping energy to separate salts from the water. These are common in homes and businesses.
Electrical energy is used for membrane-based systems and thermal energy is used for distillation systems. Some hybrid plants combine both membrane and distillation.
Most desalination plants in the world use fossil fuels to power them, but it’s even better to power them with nuclear energy. The new fleet of Small Modular Nuclear Reactors (SMRs) are ideal as they produce both thermal energy and electrical energy without producing greenhouse gases.
But only 15 out of the thousands of desalination plants operating today worldwide are powered by nuclear. A small one is at the Canyon Diablo Nuclear Plant in California, slated to be closed soon. The plant could power several huge desalination plants for decades that could desalinate its own cooling water, removing the most commonly stated problem with the plant.
In contrast, all nuclear-powered naval vessels routinely use nuclear energy to desalinate seawater.
SMRs, like NuScale’s, allow places with smaller electrical grids and limited infrastructure to add new electrical and water capacity in small increments and allow countries to site them as needed at many distributed locations. NuScale’s small power module is in its last stages of licensing by the Nuclear Regulatory Commission and will be ready in only a few years.
NuScale’s small power modules are about 60 MW each and up to 12 of them can be put together to make a power plant up to 720 MW – a 12-pack. They use standard 17×17 PWR fuel assemblies, but only at half the height, with an average U235 enrichment of only 3.8%. A single NuScale nuclear power module is 76-feet tall and 15-feet in diameter, and sits in a plant covering 32 acres or only 0.05 square miles.
Refueling of any SMR does not require the nuclear plant to shut down. The small size and large surface area-to-volume ratio of the reactor core, that sits below ground in a super seismic-resistant heat sink, allows natural processes to cool it indefinitely in the case of complete power blackout, with no humans needed to intervene, no AC or DC power, no pumps, and no additional water for cooling.
This reactor cannot melt down.
Studies by Ingersoll and others show how nuclear power and desalination can be coupled, and how much it costs. They coupled a NuScale power plant with eight modules to each of the desalination technologies – Multiple Effect Distillation (MED) and Multi-Stage Flash distillation (MSF) with either high pressure (HP) steam taken before admission into the turbine, medium pressure (MP) steam taken from a controlled extraction of the turbine, and low pressure (LP) steam taken from the exhaust end of the turbine, and reverse osmosis (RO).
They sized the desalination plant to have a production capacity of 50 million gallons per day (190,000 m3/day) of drinking water, typical of a large municipal desalination plant like the Carlsbad Desalination Plant, and that can support a population of 300,000.
The table below summarizes their economic analysis. For drinking water, the NuScale-RO design is the cheapest and produces the most water per energy used, with LP-MED distillation a close second. Since a NuScale power plant will last at least 80 years, the payback is even better.
There are other technologies that have been, and are being, used as well, including the more economical water reuse. The City of Redlands in California is using a membrane bioreactor technology from GE that recycles over 6 million gallons/day of municipal wastewater.
Whatever technologies are selected, southern California needs to build the equivalent of 30 desalination plants the size of Carlsbad’s to produce over a billion gallons a day, solving most of the water problems of southern California. The Central Valley would need another 30 plants to deal with its agricultural needs as its groundwater is becoming increasingly salty.
Powered by SMRs, these plants would more than pay for themselves by their own revenue, although a small water tax would get them started faster.
California better get moving. It’s been a reasonable two years, but more MegaDroughts are on the way.
Amazon’s “smart” homes locked people out of their homes, and prevented their refrigerators from working
How Amazon Outage Left Smart Homes Not So Smart After All
By Isabella Steger
December 7, 2021
The outage at Amazon.com Inc.’s cloud-computing arm left thousands of people in the U.S. without working fridges, roombas and doorbells, highlighting just how reliant people have become on the company as the Internet of Things proliferates across homes.
The disruption, which began at about 10 a.m. Eastern time Tuesday, upended package deliveries, took down major streaming services, and prevented people from getting into Walt Disney Co.’s parks.
Affected Amazon services included the voice assistant Alexa and Ring smart-doorbell unit. Irate device users tweeted their frustrations to Ring’s official account, with many complaining that they spent time rebooting or reinstalling their apps and devices before finding out on Twitter that there was a general Amazon Web Services outage. Multiple Ring users even said they weren’t able to get into their homes without access to the phone app, which was down.
Others said they weren’t able to turn on their Christmas lights.
Smart lightbulbs stopped responding to voice commands, many people reported.
Basic household chores also become impossible for some.
The outage prompted people to reflect on the pitfalls of having a “smart” home that’s overly dependent on not only the internet, but one company in particular — while those with “dumb” homes gloated that their fridges and light switches were working just fine.
Several of the affected AWS operations were on the East Coast. AWS said about nine hours later that it had resolved the network device issues that led to the outage.
Germany’s phaseout of nuclear power is causing an increase in the use of fossil fuels, which is causing more than 1,100 additional deaths each year
This is a quote from a scientific paper on Germany’s phaseout of nuclear power:
“Put another way, the phase-out resulted in more than 1,100 additional deaths per year from increased concentrations of SO2, NOx, and PM. The increase in production from hard coal plants is again the key driver here, making up roughly 80% of the increase in mortality impacts.”
Source: Page 25 at this link https://www.nber.org/system/files/working_papers/w26598/w26598.pdf
Either the people who support this phaseout are extremely illiterate when it comes to science, or they are deliberately killing these people. I wonder which one it is.
R.I.P. Grant Imahara

Grant Imahara, Host of ‘MythBusters’ and ‘White Rabbit Project,’ Dies at 49
July 13, 2020
An electrical engineer and roboticist by training, he worked for a long time at Lucasfilm’s THX and Industrial Light and Magic divisions.
Grant Imahara, an electrical engineer and roboticist who hosted the popular science show MythBusters and Netflix’s White Rabbit Project, has died. He was 49.
Imahara died suddenly following a brain aneurysm, The Hollywood Reporter has learned. “We are heartbroken to hear this sad news about Grant. He was an important part of our Discovery family and a really wonderful man. Our thoughts and prayers go out to his family,” a representative for Discovery said in a statement on Monday.
An electrical engineer and roboticist by training, he joined Discovery’s MythBusters in its third season, replacing Scottie Chapman and was with the show until 2014 when he left with co-hosts Kari Byron and Tory Belleci. The trio would reunite in 2016 for Netflix’s White Rabbit Project which lasted for one season. On MythBusters, Imahara used his technical expertise to design and build robots for the show and also operated the computers and electronics needed to test myths.
While part of the Mythbusters team, he sky-dived and drove stunt cars, on film sets he came into contact with some of the most iconic characters in screen history, installing lights onto Star Wars’ R2-D2, creating the robot Geoff Peterson for The Late Late Show With Craig Ferguson and working on the Energizer Bunny.
On Monday evening, Imahara’s MythBusters and White Rabbit Project co-host Byron tweeted, “Sometimes I wish I had a time machine,” and included a picture with Imahara and Belleci.
Later on Monday, Mythbusters co-host Adam Savage also tweeted: “I’m at a loss. No words. I’ve been part of two big families with Grant Imahara over the last 22 years. Grant was a truly brilliant engineer, artist and performer, but also just such a generous, easygoing, and gentle PERSON. Working with Grant was so much fun. I’ll miss my friend.”
Born in Los Angeles, Imahara studied electrical engineering at the University of Southern California (though he briefly had doubts and wanted to become a screenwriter) before combining the two passions and landing a post-graduation gig at Lucasfilm-associated THX labs. In his nine years at Lucasfilm, he worked for the company’s THX and Industrial Light and Magic (ILM) divisions. In his years at ILM he became chief model maker specializing in animatronics and worked on George Lucas’ Star Wars prequels, as well as The Matrix Reloaded, The Matrix Revolutions, Galaxy Quest, XXX: State of the Union, Van Helsing, The Lost World: Jurassic Park, A.I. Artificial Intelligence and Terminator 3: Rise of the Machines.
In 2000, Imahara also competed in Comedy Central’s BattleBots with a robot he built himself called “Deadblow” that won two Middleweight Rumbles, was the first season’s Middleweight runner-up and became the third season’s first-ranked robot.
As computer graphics began to supplant model-making in the aughts, former ILM colleague Tony Belleci suggested Imahara come aboard Mythbusters, the Discovery show Belleci co-hosted. As a co-host, he became a self-described “human guinea pig,” though if they determined a situation unfit for humans, they created machines to test them in their place.
Imahara also starred in several episodes of the fan-made web series Star Trek Continues. He played Hikaru Sulu, a lieutenant, helmsman and third officer on the USS Enterprise, in the show that was an unofficial continuation of Star Trek: The Original Series.
In a 2008 interview with Machine Design, Imahara told the publication that he wanted to be an engineer because “I liked the challenge of designing and building things, figuring out how something works and how to make it better or apply it in a different way. When I was a kid, I never wanted to be James Bond. I wanted to be Q, because he was the guy who made all the gadgets. I guess you could say that engineering came naturally.”
Something called the “Good Country Index” ranks the U.S. at #38 in “Science and Technology,” while the #1 country in that category is the Ukraine
This is the link to wikipedia’s article on something called the “Good Country Index.”
For the year 2017 (the most recent year available), in the category called “Science and Technology,” the U.S. is ranked all the way down at #38.
Meanwhile, the #1 country in that same category is the Ukraine.
Those two facts are enough to tell me that the “Good Country Index” has no credibility whatsoever.
If you’re interested in other indexes that do have a lot of credibility, I recommend these three:

The woman in this video talks about what it’s like for her and her family to live off grid with solar panels and batteries. She and her family are real environmentalist who practice what they preach. She says there are some inconveniences, but that they have manged to get used to them. She also says their daily electric usage fell from 60 kwh to between 4 and 6, not counting their limited use of air conditioning, which brings their daily usage up to 10.

Uber should release its camera footage of its fatal crash to the public
Two days ago, a self driving Uber car crashed into and killed a woman in Arizona. The car had a backup human driver behind the wheel who had the ability to take control at any time. The woman who got killed was walking in the street but was not in a crosswalk.
In my opinion, the government should get a warrant from a judge to require Uber to release its camera footage of the collision to the public. As long as we don’t get to see the footage, we can only speculate as to who was at fault.
If it was in fact Uber’s fault, then the public has a right to know, and Uber should be required to pay $10 million to the family of the victim. (I also believe that anyone who fakes such an accident in order to commit insurance fraud should get 10 years in jail for insurance fraud, in addition to whatever punishment they get for killing someone.)
If it’s the pedestrian’s fault, then knowing this information would prevent people form mistakenly thinking that self driving cars are more dangerous than they actually are.
So far, Uber’s self driving cars have a death rate of one death per approximately 2 million miles. By comparison, human driven cars have one death for approximately every 100 million miles. These are just rough numbers – they are not exact. And the sample size for Uber’s self driving cars is too small. However, from what we know, so far, Uber’s self driving cars have a death rate per mile which is approximately 50 times that of human driven cars. If this death was the fault of the pedestrian, then it doesn’t give any reason to be afraid of self driving cars. But if the death is Uber’s fault, then it’s a sign that something is seriously wrong with Uber’s self driving cars, even though the sample size is small. In cases of life and death, even one death is too many when only 2 million miles have been driven. The sample size is small, but that doesn’t change the fact that a person is dead.
Miami bridge that collapsed lifted into place without suspension cables, support tower
Miami bridge that collapsed lifted into place without suspension cables, support tower

The pedestrian bridge that collapsed in Miami was designed as a suspension bridge, but the central tower typical of such a structure wasn’t in place when the main span was lifted into place Saturday.
Florida International University posted pictures of the bridge as envisioned, with a tall central column and cables stretching down to hold the bridge, shaped like a sailboat. The design is called a cable-stayed bridge, which is a type of suspension bridge.
Cable-stayed bridges have cables attached directly from the column to the span, while suspension bridges string cables between towers and have other cables descend to the span.

Amjad Aref, a professor at University of Buffalo’s Department of Civil, Structural and Environmental Engineering, said a suspended bridge is typically built gradually, with the center tower or towers erected early.
Pictures from the scene of the collapse don’t show a central tower.
“Whoever is going to investigate, they will ask the fundamental question: shouldn’t the tower be there, and the cables ready to connect to the structure, when you lift it?” Aref said. “That’s a question for them to answer.”
Andrew Hermann, past president of the American Society of Civil Engineers, said cable-stayed bridges are built in stages, with pieces of roadbed placed on piers before the cables are attached. At each phase in the project, the supports such as piers are designed to hold the entire weight placed on them, he said.
“When you’re doing staged construction like this, what you have to make sure is that at each stage that the structure is strong enough for the loads that are on the bridge,” Hermann said. “The engineering, both design and the construction engineering, should have taken that into account with the bridge in that condition.”

National Transportation Safety Board chairman Robert Sumwalt led a team of investigators Thursday to determine what went wrong and what could prevent similar collapses in the future.
“That’s part of our investigation,” Sumwalt said of the lack of central column.
Suspension bridges are popular across the country — from the George Washington Bridge in New York to the Golden Gate Bridge in San Francisco— because the way they are built allows for construction across rivers.
The Kosciuszko Bridge, which carries Interstate 278 called the Brooklyn-Queens Expressway over Newtown Creek in New York City is a cable-stayed bridge. So is the John James Audubon Bridge across the Mississippi River in Louisiana and the Sunshine Skyway Bridge in Tampa.
Those bridges are much longer and heavier than the bridge at Florida International University, which was built to only handle pedestrians, not cars and trucks.
“I wish I would be on that kind of investigation, to be honest with you, because in this country we build so many cable-stay bridges for carrying trucks, not pedestrians, and all of them work fine,” Aref said. “The spans, from one end to the other, is much larger than that.”
Typically on such bridges, the central tower or towers are erected first, Aref said. Then slabs of pavement are lifted into place, alternated from each end and connected to the shortest cables closest to the span connected to the main tower, he said.
“When they cross rivers, you don’t have the luxury of having a big bridge in one piece and moving it in place like this,” Aref said.
Robert Bea, a professor of engineering and construction management at the University of California, Berkeley, told the Associated Press that without knowing precisely what happened, the “innovative installation” was risky because the bridge spanned a heavily traveled thoroughfare.
“Innovations take a design firm into an area where they don’t have applicable experience, and then we have another unexpected failure on our hands,” Bea said after reviewing the bridge’s design and photos of the collapse.
The $14.2 million FIU bridge was designed under a process called “accelerated bridge construction” that allowed for larger sections to be built and then lifted into place. A 174-foot section weighing 950 tons was hoisted and rotated into place across the six-lane road Saturday. When finished, the bridge would have been 289 feet long and 109 feet tall.
Aref said he was unaware of such a large section of bridge being put in place without supporting cables.
“I don’t want to speculate. From a structural-engineering point of view, the forensic engineers won’t take long to figure out what happened,” Aref said. “I think it is not a long investigation. There are glaring things.”
Munilla Construction Management, a Miami-based construction management firm, won the bridge contract with FIGG Bridge Engineers of Tallahassee. Munilla said it would cooperate with the investigation. FIGG said in a statement “in our 40-year history, nothing like this has ever happened before.”
But FIGG was fined in 2012 after a 90-ton section of bridge collapsed on railroad tracks in Virginia. Munilla was accused of substandard work in a lawsuit filed this month after a makeshift bridge collapsed at Fort Lauderdale International Airport.
Occupational Safety Health Administration records show fines totaling more than $50,000 against Munilla for 11 safety violations in the past five years for complaints about unsafe trenches, cement dust and other problems.
