Engineers Save a Life

photo of car resting in river

This photo was taken by the driver’s parents when they arrived. It doesn’t show much of what it went through to get there, but it gets most of the point across. The picture was taken 200 feet away and looking down from the road.

I got into a major accident today that I was able to somehow walk away from. I lost control of my car and went off of a cliff into boulders, and after flipping a few times, settled in the river. I walked away with cuts on my hands from the broken glass and a bruise that runs from my chest over my left shoulder where my seat belt held me in place.

I shouldn’t be alive discussion on Reddit.

swapsrox: Time to send a letter to the manufacturer thanking them for their safety design! I guarantee your letter will be put on an engineer’s wall, and they’ll know there is a reason they go to work every day.

cmdshftn: Great engineering saved your life. The vehicle’s safety systems from the seatbelt to the crumple zones to the design of the seat kept you safe and alive despite all hell going on around you. Please write a letter to the manufacturer thanking their design team, but above all, follow up with whoever you need to in that jurisdiction to find out why there isn’t a guard rail on that road! Vehicle safety helps, but great road design to prevent an accident like yours helps more!

Introduction Video on 3D Printing

3D printing is an amazing technology that opens up great opportunities for us to enjoy life. The future is great. It is exciting to see how quickly advances are being made in this area. I think the ability to print replacement parts is a huge benefit. And the creative uses people will put these printers too will be a joy to see.

Working as a Software Developer

For most of my career I have been focused on management improvement – helping organizations improve results. Technology plays a big role in that and along the way I found myself becoming a programer for a while; and then a software development program manager. This is a good post on working as a software developer:

reading code is a very important skill. Before a program can be modified, you need to understand what it does, and how it does it. Only then can new functionality be added so it fits in with the existing structure, and without breaking anything. Reading and understanding a program can be a major effort, and one sign of a well-designed program is that it is relatively straight-forward to modify it.

Write for people first, computer second. The code you write will be read many times in the future (by you, or another developer). The computer doesn’t care how the code is written, so make it as easy as possible to understand for the next person that has to read it. A corollary to this is: don’t be too clever. It’s better to be clear than to be clever.

When there is a compelling need to write for the computer first and people second make sure to document that code well. For example, some code that is extremely dense and complex and confusing but greatly enhances the efficiency of a critical area of code.

I recently wrote a book, Management Matters: Building Enterprise Capability. There are many great things about a career in software development. It certainly is also challenging and not for someone looking for the easiest career but I have seem a higher percentage of happy software developers than I have seen in any other discipline.

Arduino Introduction Video Tutorial

Arduino is a very cool open source programable hardware engineering initiative. It is great for kids and adults who like to learn and create electronic devices. The Arduino Starter Kit is a great education gift for those interested in such things.

The video explains how to build a basic circuit with the Arduino board, and how to use each of the basic components such as LEDs, switches, and resistors. See more videos on related topics. Massimo Banzi, the co-creator and CEO of Arduino, and seen in the videos, also has a book: Getting Started with Arduino.

The Eagle Has Landed

Neil Armstrong and Buzz Aldren land on the moon: July 20, 1969. As Neil Armstrong took humanity’s first step onto the Moon he said:

That’s one small step for man, one giant leap for mankind.

Citizen Science: Use Your Smart Phone to Help Scientists

10 Ways You Can Use Your Smartphone to Advance Science by Matt Soniak

Scientists have started to use the abilities and prevalence of smartphones to their advantage, creating apps specifically for their studies and crowdsourcing observation and data collection. When almost everyone has an Internet connection, a camera, and a GPS unit right in their phone, almost anyone can gather, organize, and submit data to help move a study along.

The Indicator Bats Program (iBats), a joint project of the Zoological Society of London’s Institute of Zoology and The Bat Conservation Trust, got its start with a couple of researchers working in Transylvania (of course) in 2006. The idea of the project is to identify and monitor bat populations around the world by the ultrasonic echo-location calls they use to navigate and find prey.

The goal of Project NOAH (Networked Organisms and Habitats) is pretty ambitious: “build the go-to platform for documenting all the world’s organisms.” Their app has two modes. “Spottings” lets you take photos of plants and animals you see, categorize and describe them and then submit the data for viewing on NOAH’s website and use by researchers for population and distribution studies.

Invasive plants and animals can crowd out natives, compete with them for food sources and alter the fire ecology of an ecosystem, disrupting its natural balance. Researchers and programmers from UCLA, the Santa Monica Mountains National Recreation Area and the University of Georgia have teamed up to create the What’s Invasive citizen science program and smartphone app. Volunteers can use the app to look up lists of the top invasive species in their area, created by National Park Service rangers and biologists. If they spot a plant or animal from the list, they submit a geo-tagged observation, with optional picture and text notes, so that scientists can locate, identify, study try to remove the species.

Great stuff.

The Chemistry of Fireworks

The video features John A. Conkling, Ph.D., who literally wrote the book on fireworks — he is the author of The Chemistry of Pyrotechnics.

The earliest documentation of fireworks dates back to 7th century China.

A Syrian named Hasan al-Rammah wrote of rockets, fireworks, and other incendiaries, using terms that suggested he derived his knowledge from Chinese sources, such as his references to fireworks as “Chinese flowers”.

Chinese fireworks began to gain popularity around the mid-17th century.

Repair Cafes in The Netherlands

Repair Cafes in The Netherlands Give Life Back to Broken Objects

A new brand of DIY self-sufficiency is spreading across The Netherlands. Skilled craftswomen, mechanics, seamstresses, and handypersons are banding together to resist disposable consumer culture. It is the rise of the Repair Cafe, a place where neighbors get together to extend the life of their material belongings. “Fixers” mend clothes, restore furniture, rehabilitate electrical appliances, and enjoy each other’s company while industriously toiling away. The first cafe was founded by Martine Postma in Amsterdam in October of 2009. Today, there are 20 fully operational Repair Cafes, and 50 more in the planning stages.

I really like these efforts. We throw away too much stuff that has plenty of useful life left. Also it is a great way to build community. And it is an interesting way to learn about products we use everyday (both by fixing them and having your items fixed). The throw away culture is something we should aim to change. By these actions and also by engineers designing products to be fixed instead of thrown away. I donated to a similar fixer collective in Brooklyn via Kickstarter.

NASA Biocapsules Deliver Medical Interventions Based Upon What They Detect in the Body

Very cool innovation from NASA. The biocapsule monitors the environment (the body it is in) and responds with medical help. Basically it is acting very much like your body, which does exactly that: monitors and then responds based on what is found.

The Miraculous NASA Breakthrough That Could Save Millions of Lives

The Biocapsules aren’t one-shot deals. Each capsule could be capable of delivering many metred doses over a period of years. There is no “shelf-life” to the Biocapsules. They are extremely resilient, and there is currently no known enzyme that can break down their nanostructures. And because the nanostructures are inert, they are extremely well-tolerated by the body. The capsules’ porous natures allow medication to pass through their walls, but the nanostructures are strong enough to keep the cells in one place. Once all of the cells are expended, the Biocapsule stays in the body, stable and unnoticed, until it is eventually removed by a doctor back on Earth.

Dr. Loftus [NASA] thinks we could realistically see wildspread usage on Earth within 10 to 15 years.

The cells don’t get released from the capsule. The cells inside the capsule secrete therapeutic molecules (proteins, peptides), and these agents exit the capsule by diffusion across the capsule wall.

NASA plans to use the biocapsules in space, but they also have very promising uses on earth. They can monitor a diabetes patient and if insulin is needed, deliver it. No need for the person to remember, or give themselves a shot of insulin. The biocapsule act just like out bodies do, responding to needs without us consciously having to think about it. They can also be used to provide high dose chemotherapy directly to the tumor site (thus decreasing the side effects and increasing the dosage delivered to the target location. Biocapsules could also respond to severe allergic reaction and deliver epinephrine (which many people know have to carry with them to try and survive an attack).

It would be great if this were to have widespread use 15 years from now. Sadly, these innovations tend to take far longer to get into productive use than we would hope. But not always, so here is hoping this innovation from NASA gets into ourselves soon.
