Rebuilding I-40

1 Comment

The recent devastation in western North Carolina from hurricane Helene is truly mind-boggling. There is no doubt that it will be multiple years before the roads there are back to anything resembling "normal." I'm sure the death toll will also only go up from where it is now, which is heartbreaking. Watching on the news, one can't help but to feel utterly helpless.

One aspect of this ever-changing story that will be fascinating to watch will be how the North Carolina DOT chooses to repair the collapse of I-40:

Portion of I-40 which collapsed

In addition to the curved section shown above, a longer, straighter section also washed out, with the adjacent river coming perilously close to the road's edge. From a logistical perspective, it's going to be very interesting to see how they choose to fix this collapse. Is it better to cut into the neighboring rock and essentially shift the road away from the river's edge? Do you try to backfill the river somehow? I can only imagine the engineering challenges that await this repair.

A terrific YouTube channel to follow for this kind of content is Casey Jones - Professional Engineer. He often digs deep into stories such as this, providing his own insights as a certified civil engineer. The video below has some good footage of the damage the highway received, along with some brief commentary about the challenges ahead.

Northern Ontario man solves local legend, finds vintage liquor at bottom of lake

1 Comment

As a kid, Jason Ploeger remembers people searching in the waters of Larder Lake for a taxi cab that sank beneath the surface decades before.

And of course, like everyone else in the small northern Ontario town near the Québec border that was once a major gold mining centre, he heard the stories.  

"Growing up in the town, we all heard the legend," said Ploeger.

"Everybody you talked to had a different story."

The version of the story Ploeger heard the most was that the taxi went through the ice of Larder Lake on the way to a Christmas party, carrying liquor and holiday bonuses for local gold miners.

But there were other stories that the cab was hauling gold bars or gold ore, or that is was a bootlegger delivering alcohol to mining camps in the Larder Lake area. 

Ploeger spent 35 years searching for the taxi and then while fishing in a local derby last year, he saw something come up on the screen of his side imager that he uses to look deep into the lake for fish. Or sunken treasure.

"Is that what I think it is?" he said to himself, seeing the outline of the back window and tires, knowing it was "obviously a car."

"I was excited. I almost gave up fishing for the day."

But instead, he marked the spot and went back later with some fellow divers, going down 15 metres into the pitch black waters of Larder Lake.

"I had one of the other divers right beside me and I'd have to shine my light right on him to see him," Ploeger said.

"It was a spooky dive."

There was no gold, but they did spot six bottles in the back of what they now know is a 1929 REO Flying Cloud.

He says he later spoke with the daughter of one of the five men who rode in the taxi that day and learned they were heading to a Christmas party at the Martin-Bird Mine when the car started to go through the ice and everyone got out safely. 

Ploeger says they brought one bottle to the surface and it "promptly exploded on my boat from the pressure," but he dipped a finger in it and said it tasted like "very, very smooth" rye whisky.

This summer, they went back down and brought up five more bottles, two of which also blew their cork on the way to the surface. 

"I do not believe it was a good whisky when it was bought," Ploeger said of drinking from one of the bottles.

"I'm not blind yet so that's a good sign."

One of the intact bottles recovered from the bottom will be auctioned off on Sept. 28 at a steak dinner and charity auction to benefit a community group called the Friends of Larder.

"I've been thinking for a while, if I ever found it, it's not my story, it's the town's story. So I figured I would donate it back to the town," Ploeger said. 

He says the car is "too fragile to remove," so it will stay at the bottom of Larder Lake for other divers to enjoy.

Ploeger says he tried some of the recovered alcohol and it was 'super smooth' but another bottle was very 'rough' whisky. (Submitted by Jason Ploeger)

"It's a weird feeling, because I've been looking, looking and looking," said Ploeger.

"And now I've seen it. I've been there. And it's over."

But he says he is still chasing down other local mysteries, including some boats sunk in the lake and a military plane that crashed in the bush nearby during the Second World War.

AquaFence's Clever Design for Anti-Flooding Barriers

2 Comments

As Hurricane Helene ravaged the southeastern United States, Tampa General Hospital managed to ward off flooding using this AquaFence system. Unlike sandbags, these barrier wall systems are reusable, and can be stored flat.


The design is simple, but ingenious: The more water they're keeping out, the stronger the structure becomes. That's because each component is L-shaped, braced diagonally with steel struts, and designed to be used with the bottom of the L pointed towards the water. As floodwaters rise, they weigh down on the bottom of that L, anchoring each component in place. The upright of the L cannot collapse, because it is held fast by the high tensile strength of the steel braces.

In this video released by the hospital, you can see how effective the 9-foot-tall barriers are:

Being Raised by the Internet

1 Comment

I grew up relatively poor. I was fortunate enough to have a roof over my head, clean water, electricity, a computer, internet, and cable tv. But food was often harder to come by. This may seem like a contradiction, but when your mom has left to marry her uncle and your dad has schizophrenia, you aren’t really in charge of how the money is spent.

Starting at the age of 12, I was given $20 a week for my food. (If it was a good week. Otherwise it might $10 or even $0). During the school year that meant I just had to make that stretch for dinner and the weekends — I had free school lunch. But in the summer, that made things quite a bit harder. One week, I had only a few jars of sprinkles left in the top of our pantry.

When I did have money for food, I had to buy it. Luckily there were a few restaurants and a large grocery store about a half-mile walk away. I still remember the first time I made that trip alone. It was snowing, I didn't have a heavy coat and my brother didn't want to go with me. I was scared, but eventually gave into the hunger and went and bought something at the grocery store. From then on I found a new freedom.

I didn't know how to cook so my meals at home largely consisted of ramen and Velvetta queso and chips. Two bags of tortilla chips, a jar of salsa, and a brick of velvetta cost $10. So that would usually be about half my week's worth of food. Craving something else, I would often go to the local Qdoba and get a burrito. At $6.35 it wasn't a great spend of my money. But sometimes the employees there would give me the employee discount, I guess they realized I needed it. If I really wanted to feel full and have something tasty, I'd get a large fry at the Penn Station for $3.75. A full belly was a great feeling.

Computers

Computers became my outlet away from all of this. In an effort to have more computer time to himself, my brother found a computer out by the dumpster, brought it in, and told me it was my computer now. I knew very little about computers at the time but I knew two things 1) I needed a wireless card. 2) I needed to get Windows ME off this thing (I didn't know any of the passwords for the accounts). Luckily a kid at school and some people at church had mentioned Linux. I burned CDs for Fedora, CDs for Suse, but I couldn't get either of them working. Then I learned about Ubuntu and their live CD. I got it working!

But the internet didn't work even after I installed my wireless card. Little did I know, that I had stumbled into a classic blunder, linux and wireless cards. After a lot of googling, I figured out I could install this thing called ndiswrapper. Problem, I had no internet. So after many CDs burned resolving the dependency tree to compile ndiswrapper (I had no idea what I was doing), I got it working!

I was hooked. Computers became my escape. I spent so much time tinkering. Countless hours on things like hackthissite.org and projecteuler.net. I would learn new languages, build pointless projects, configure my Linux install, trying for the 100th time to get xgl working seamlessly. Computers were the distraction I needed away from my day-to-day life.

The Kindness of Strangers

I never thought I'd amount to much in life. I never imagined having a job that paid well. I definitely never imagined this little hobby I had as a kid would give me so much.

When I look back and think about those times, I'm amazed but how much I owe to people who I never met. People who never met me, never heard of me. People whose work was not aimed at me in the slightest. I am where I am today thanks to people's willingness to share their work openly. The free tutorials I followed on the internet, the open source software I read, the open source software I used, tech news, resources like w3schools, random tech blogs, all formed the backbone of my education. They all taught me the skills I needed to escape the poverty I grew up in.

These random strangers gave me the confidence I needed. They showed me things I couldn't have learned in school. They set me up to succeed in life. They raised me.

The Impact of Being Open

I am forever indebted to these people. They weren't all famous people, nor successful people. Some of them had companies that failed. Some of their blogs were obscure and lost to time. (I doubt I will ever find the tutorial for making a website in flash+php+xml+mysql that I once followed). I'm sure some of them felt like failures. Perhaps they didn't get rich like they hoped, or popular, or never succeeded in changing the world. But they all had one thing in common, they decided to openly and freely share their work.

They may not have set out to share out of altrusitic motivations. I am certain they never intended to inspire a 12 year-old kid to find a better life. But it doesn't matter their motivations. They changed my life. All I can say is thank you. Thank you for sharing your work. Thank you for your blogs posts, your tutorials, thank you for your slashdot comments, for your posts on digg. No matter how small your contribution, it mattered to me. You changed my life. Thank you.

Visualizing Weather Forecasts Through Landscape Imagery

Visualizing Weather Forecasts Through Landscape Imagery

house

Traditional weather stations often display sensor readings as raw numerical data. Navigating these dashboards can be overwhelming and stressful, as it requires significant effort to locate, interpret, and visualize specific parameters effectively.

Viewing a landscape image feels natural to the human eye. The calming effect of observing landscape elements reduces stress and requires minimal effort, allowing for a more relaxed visual experience.

The method below demonstrates how to encode weather information within a landscape image, with no or minimal reliance on numerical data.

Encoding principles

The landscape depicts a small house in the woods. The horizontal axis of the image represents a 24-hour timeline, starting from the current moment on the left, marked by the house, and extending to the conditions of the next day on the right. Various landscape elements distributed along the vertical axis symbolize weather events and conditions. The further an event is from the present, the farther it is positioned to the right in the image.

encode

The following information can be encoded within the landscape image:

  • Time markers to simplify timeline navigation:
    • Sunrise and sunset times
    • Noon and midnight
  • Weather forecast information:
    • Wind direction and strength
    • Temperature fluctuations
    • Maximum and minimum temperature values
    • Cloud cover
    • Precipitation
  • Current weather conditions:
    • Temperature
    • Atmospheric pressure
  • Non weather events:
    • Birthdays
    • Holidays

Implementation

The image generation code is written in Python using the Pillow library and is based on data from OpenWeather. The image is designed specifically for use on a 296x128 E-Ink display. The code tested on Python 3.9.

 Landscape image                                       Description
example It’s around noon, with clear skies and a few clouds expected. A moderate north wind will develop overnight. Temperatures are currently rising but will begin to fall after sunset, reaching their lowest point before sunrise. During this time, the wind is expected to shift to the northeast.
example The sun is rising and it will be a hot sunny day with a light southeast breeze. The temperature will remain high even after sunset, and the wind will shift to the east, becoming stronger throughout the evening.
example It will be cold and rainy throughout the day and night. The south wind will shift to the northeast overnight.

Running the code

Preparing environment Linux

./makevenv.sh
source .venv/bin/activate

Preparing environment Windows

makevenv.bat
.venv/Scripts/Activate

Image creation test

Update OWM_KEY variable in the weather_landscape.py file with your OpenWeather API key.

python run_test.py

Run server

python run_server.py

Setup

The hardware setup includes an ESP32 development board and 2.9inch E-Ink display module. Currently, the setup only displays an image sourced from the internet, updating every 15 minutes. It is uncertain whether the image generation code can be adapted for use with MicroPython on the ESP32 at this time.

The Death of the Minivan

1 Comment

The minivan dilemma: It is the least cool vehicle ever designed, yet the most useful. Offering the best value for the most function to a plurality of American drivers, a minivan can cart seven passengers or more in comfort if not style, haul more cargo than many larger trucks, and do so for a sticker price roughly a quarter cheaper than competing options. Even so, minivan sales have been falling steadily since their peak in 2000, when about 1.3 million were sold in the United States. As of last year, that figure is down by about 80 percent. Once sold in models from more than a dozen manufacturers, the minivan market now amounts to four, one each from Chrysler, Honda, Toyota, and Kia.

On account of the dilemma, a minivan is typically purchased under duress. If you live in a driving city, and especially if you have a family, a minivan conversation will eventually take place. Your older, cooler car—perhaps your Mini Cooper or your spouse’s Honda CR-V—will prove unfit for present purposes. Costco cargo, loads of mulch, sports equipment, and holiday loot all need a place to go. The same is true of car seats, which now are recommended for children as old as 7. And so, before too long: “Maybe we should get a minivan.”

This phrase is uttered with an air of resignation. The minivan was popular, but it was never cool, not even in its youth, during the 1980s. Now it’s middle-aged: The first of its type came out in ’83, which makes the minivan an elder Millennial, and it’s no more attuned than your average 41-year-old to recent trends. But why, exactly, has it earned so much derision through the years? And why was the minivan replaced, almost altogether, by the SUV?

The minivan arrived, way back when, as a savior. When Chrysler, under the former Ford chief Lee Iacocca’s direction, first conceived of the design in the late 1970s, Americans who wanted room to cart more kids and goods had only a couple of options. One was the land-yacht-style station wagon, perhaps in avocado green with faux-wood paneling. Lots of kids could pile onto its bench and jump seats, while the rear storage, accessible by hatch, allowed for easy loading. These cars were somewhat functional, but they didn’t seem that safe. The suburban family’s other choice was the full-size van—a big, boxy transport or utility vehicle. The gas for these was also pricey, and their aesthetic felt unsuited to domesticity. By cultural consensus, vans were made for plumbers, kidnappers, or ex–Special Forces domestic mercenaries.

Chrysler’s minivan would steer clear of those two dead ends, and carry American families onto the open roads toward, well, youth soccer and mall commerce. It really did bring innovation: ample seating organized in rows with easy access, the ability to stow those seats in favor of a large cargo bay, a set of sliding doors, and smaller features that had not been seen before, such as the modern cupholder. And it offered all that at an affordable price with decent fuel economy.

[Read: The hardest sell in American car culture]

Pickup was quick. In the first year after introducing them, Chrysler sold 210,000 Dodge Caravans and Plymouth Voyagers, its initial two models. Overall minivan sales reached 700,000 by the end of the decade, as the station wagon all but disappeared. But the new design also generated stigma: As the child of the station wagon and the service van, the minivan quickly came to represent the family you love but must support, and also transport. In a nation where cars stood in for power and freedom, the minivan would mean the opposite. As a vehicle, it symbolized the burdens of domestic life.

That stigma only grew with time. In 1996, Automobile magazine called this backlash “somewhat understandable,” given that the members of my generation, who were at that point young adults, had “spent their childhoods strapped into the backseat of one.” Perhaps it was childhood itself that seemed uncool, rather than the car that facilitated it. In any case, minivans would soon be obsolesced by sport utility vehicles. The earliest SUVs were more imposing than they are today: hard-riding trucks with 4×4 capabilities, such as the Chevrolet Suburban and the Jeep Wagoneer. These were as big as or even bigger than the plumber-kidnapper vans of the 1970s, and they got terrible gas mileage, cost a lot of money, and were hard to get in or out of, especially if you were very young or even slightly old. Yet the minivan’s identity had grown toxic, and for suburban parents, the SUV played into the fantasy of being somewhere else, or doing something better.

[Read: Minivans for minigarchs]

The SUV’s promise was escape from the very sort of family life that the minivan had facilitated. In 2003, The New York Times’ John Tierney recounted how the new class of vehicles had taken over. “The minivan became so indelibly associated with suburbia that even soccer moms shunned it,” he explained. “Soon image-conscious parents were going to soccer games in vehicles designed to ford Yukon streams and invade Middle Eastern countries.” At the same time, the SUVs themselves were changing. The minivan had been built from parts and designs for a car, not a van. SUV manufacturers followed suit, until their vehicles were no longer burly trucks so much as carlike vehicles that rode higher off the ground and had a station-wagon-style cargo bay. Few even had more seats than a sedan. As the early minivans were to vans, so were these downsized SUVs to the 4x4s that came before them.

Functionally, the minivan is still the better option. It is cheaper to buy and operate, with greater cargo space and more seating and headroom. Still, these benefits are overshadowed by the minivan’s dreary semiotics. Manufacturers have tried to solve that problem. When my family reached the “Maybe we should get a minivan” milestone, I noticed that some models of the Chrysler Pacifica now offered, for a premium, blacked-out chrome grills and rims. But to buy a poseur “sport van,” or whatever I was meant to call this try-hard, cooler version of the uncool minivan, struck me as an even sadder choice.

Beyond such minor mods, the industry hasn’t really done that much to shake away the shame from the minivan’s design. I suspect that any fix would have to be applied at the level of its DNA. The minivan was the offspring of the wagon and the van. To be reborn, another pairing must occur—but with what? Little differentiation is left in the passenger-vehicle market. Nearly all cars have adopted the SUV format, a shoe-shaped body with four swinging doors and a hatch, and true 4x4s have been all but abandoned. Perhaps the minivan could be recrossed with the boxy utility van, which seems ready for its own revival. This year, Volkswagen will begin selling a new electric version of its microbus, one of the few direct precursors to the minivan that managed to retain an association with the counterculture despite taking on domestic functions.

However it evolves, the minivan will still be trammeled by its fundamental purpose. It is useful because it offers benefits for families, and it is uncool because family life is thought to be imprisoning. That logic cannot be overcome by mere design. In the end, the minivan dilemma has more to do with how Americans think than what we drive. Families, or at least vehicles expressly designed for them, turned out to be lamentable. We’d prefer to daydream about fording Yukon streams instead.
