Larry Page and Sergey Brin Interview Webcast

This interview and audience question and answer took place last week at the end of the Google Zeitgeist conference. Some interesting notes from Sergey:

  • I like to see us not focus on maintaining Google’s culture but to improve it – continuous improvement (he specifically mentions how the infrastructure they have in place now allows them to experiment in ways that were not possible before – a reminder of Google’s focus on the scientific method and Experimenting Quickly and Often).
  • Google still follows their model of focusing 70% of the effort on core business (search) and 20% on related activities and 10% on “anything goes” (new business areas).
  • While not directly related to Google he is very interested in the innovation in nanotechnology and carbon nanotubes and the present time.
  • on moving toward universal power supplies – we are talking to some companies about solutions “but I gotta be honest with you it is a harder problem than I thought”

Larry:

  • focus on Google’s mission – to organize the world’s information
  • believes there is great potential in solar power and would love to see successful companies in that industry
  • improve power supply efficiency on servers

Both:

  • discussed poor web usability practices based on sites that adopt flashy technology that make it slower and more difficult for users – flash, excessive Ajax… Larry also mentioned doing testing on the user experience – no surprise for Google and no surprise that most poorly overly fancy sites care more about what a pointy haired boss might think on seeing the flash than on users experiences and testing.

The Engineer That Made Your Cat a Photographer

photo by Binky the cat or another catThis article is the result of the first Curious Cat engineer interview. My favorite post detailed the great engineering project Jürgen Perthold undertook to engineer a camera that his cat could wear and take photos. So I decided to interview him.

The Engineer That Made Your Cat a Photographer by John Hunter:

This time I thought about our cat who is the whole day out, returning sometimes hungry sometimes not, sometimes with traces of fights, sometimes he stay also the night out. When he finally returns, I wonder where he was and what he did during his day. This brought me to the idea to equip the cat with a camera. The plan was to put a little camera around his neck which takes every few minutes a picture. After he is returning, the camera would show his day.

The Amazing CatCam is not only a great product but a wonderful engineering story. See our past post for some background on how an engineer allowed you to help your cat become a photographer. On the development of the CatCam Jürgen Perthold says, “More or less it was just a joke, born with a crazy idea.” Such a great sentiment and with wonderful results.

What path led him to the desire and ability to pursue the crazy idea and become the Curious Cat engineer of the year? He was born in Aalen, Germany. He started playing with electronics as he was 13. At 15 he added computer programming and with a friend they programmed games, applications and hardware control over the years. He studied Optoelectronics at the University of Aalen, Germany extending his knowledge further.

For the last few years he has worked for Bosch, an international manufacturing company, in the automotive hardware section. Last summer, he transfered from Germany to Anderson, South Carolina as a resident engineer for transmission control unit in a production plant for automobile parts. On a side note, the United States is still by far the largest manufacturer in the world.

The demand for the cameras is still higher than his capability to produce the cameras. He has raised the price, to limit the demand. When I first saw the prices I couldn’t believe how inexpensive it was. And, in my opinion, they are still a incredible deal. Order your CatCam now: it is a great gadget for yourself or it makes a great unique, gift. Most orders have been from the UK, Germany and the USA.

Most people don’t have technical background so they buy the full unit. But he reports that some brave souls order a kit because of price or availability although they have not done anything similar before. What a great way to challenge yourself and, if you succeed, end up with a wonderful creation when you finish.

He is in discussion with several different groups to ramp up production. The main problem is that producing the device requires electronics, optics, software, mechanics and logistics expertise. So, for the time being, he continues to modify the cameras by hand because no investments are necessary and the production can be scaled according to the demand. The required soldering, electronics and system knowledge makes it a challenge to outsource. So, for now, CatCam production is adding to the USA manufacturing output total. He is also planning to produce more products.

Jürgen believes that getting the cat camera working was not that challenging. You can take a look at his explanation of how he did so to decide for yourself. He does admit that challenges do arise if you want to produce cameras for others. To do that you must create a product that is foolproof, reliable, and easy to use and manufacture.

“I was surprised how famous one can get with ‘boring’ technical engineering stuff. I like this not only for me but for all other engineers out there who daily work hard on challenges which others don’t even understand. We as engineers make the world moving but usually we are not recognized.” Everyone enjoys the products of the labors of engineers (such as cell phones, MP3 players, cars, planes, bridges, internet connections) but few see the required knowledge, work and the people that bring those products into being.

Jürgen “hopes that I made ‘engineering’ a bit more visible to people who did not think about it before, for example, female cat owners who never had a solder iron in the hand and bought plain SOIC chips because they wanted the cat camera…”

I think he has done a great job illustrating the engineering behind the CatCam and making engineering fun. And in so doing hopefully is making more people aware of the engineers that make so many wonderful modern gadgets. Go buy a CatCam now (and if you are adventurous buy the parts and create your own – you will learn a lot about what makes all your modern gadgets work). And then send in the pictures your cat takes so everyone can see the wonderful things engineers make possible.

The photos here show the results of several new cat photographers (Binky the cat [first 2 photos] and Jacquie the cat [last 2]). Only a small percentage of CatCam owners have shared there pictures so far.

Over the next few years he would like to learn to sail, visit Yellowstone national park, walk the Camino de Santiago again, move on to other international assignment (maybe far east) and continuing raising his two children.

NSF Graduate Research Fellow Profiles

Over at my regular job I was finally able to get us to put into place something that I have wanted to for several years: profiles of past NSF Graduate Research Fellows [link broken, so link removed]. We started with probably the most famous and certainly the richest: Google Co-Founder Sergey Brin.

“Obviously everyone wants to be successful, but I want to be looked back on as being very innovative, very trusted and ethical and ultimately making a big difference in the world.”

Sergey Brin, Co-Founder of Google, graduated from University of Maryland with high honors in mathematics and computer science in 1993 and, as a NSF Graduate Research Fellow, went on to Stanford to further study Computer Science. Early in his graduate studies, he showed interest in the Internet, specifically data-mining and pattern extraction…

In his short executive biography, Brin [link broken, so link removed] lists the National Science Foundation Graduate Research Fellowship that supported him while at Stanford among his top achievements. Like NSF, Brin understands the importance of research in innovation, and sponsors it in part through Google’s “20% time” program – all engineers at Google are encouraged to spend 20% of their work time on projects that interest them.

Great Speech by Marissa Mayer on Innovation at Google

subscribe to Curious Cat Engineering Blog

Marissa Mayer speech at Stanford on innovation at Google (23 minute speech, 26 minutes of question and answers). She leads the product management efforts on Google’s search products- web search, images, groups, news, Froogle, the Google Toolbar, Google Desktop, Google Labs, and more. She joined Google in 1999 as Google’s first female engineer. Excellent speech. Highly recommended. Google top 9 ideas:

(inside these are Marissa’s thoughts) [inside these are my comments]

  1. Ideas come from anywhere (engineers, customers, managers, executives, external companies – that Google acquires)
  2. Share everything you can (very open culture)
  3. Your Brilliant We’re Hiring [Google Hiring]
  4. A license to pursue dreams (Google 20% time)
  5. Innovation not instant perfection (iteration – experiment quickly and often)
  6. Data is apolitical [Data Based Decision Makingcommon errors in interpreting data – read the related links too]
  7. Creativity loves Constraints [process improvement and innovation]
  8. Users not money (Google focuses on providing users what they want and believe it will work out)
  9. Don’t kill projects morph them

So far every time I hear one of Google’s leaders speak I am happier that I own a bit of stock – this is another instance of that.

Home Engineering: Windmill for Electricity

photo of windmill

William Kamkwamba’s Malawi Windmill:

I built my first windmill when I was 15. Over the next few years I kept refining the design. I made many modifications to the plans i found in the book. For example, I increased the blades from three to four to provide more power output. The windmill now powers lights for 3 rooms and a light over our porch outside. I also use it to power my family’s two radios. I also can charge mobile phones that the neighbors have.

Two weeks ago I used a computer for the first time. I learned about Google and searched for “windmill” and “solar energy.” I was amazed to learn how many entries there were for both subjects. My friends showed me how to create an email address and now I am on Gmail. Now I am practicing sending and receiving emails when I have access to a computer.

On Sunday, my friends from National Solar and I completed the next phase of work on my electrical system. You can see a compete set of (my first) digital photos at my new site on Flickr. I had the following goals:

1. Upgrade the power generation in the windmill
2. Upgrade the battery technology and capacity, to provide more even power for more hours at a time
3. Increase the brightness of the lighting (lumens) to make it easier for my family to accomplish tasks at night, especially to read…

Photo: Back in November, the windmill was only 5 meters (15 feet) tall compared to 12 meters (36 feet) today. I raised the height because I discovered that the best wind was just over the top of the shorter windmill.

Awesome Cat Cam

CatCam by Juergen Perthold – this great project involved taking a digital camera and some additional equipment to create a camera that his cat wore around his neck which took pictures every 3 minutes. The pictures are great. The cat got photos of several other cats and seemed to like cars.

See more cool gadgets, See our other popular posts and our cat related posts.

Sometimes I have some challenging ideas, or crazy like some other people would say. This time I thought about our cat who is the whole day out, returning sometimes hungry sometimes not, sometimes with traces of fights, sometimes he stay also the night out. When he finally returns, I wonder where he was and what he did during his day. This brought me to the idea to equip the cat with a camera. The plan was to put a little camera around his neck which takes every few minutes a picture. After he is returning, the camera would show his day.

The VistaQuest made it very easy for me, because it is able to supply my circuit also if switched off. This is because of an internal DC/DC converter which boosts the voltage from the 1.5V battery to 3.3V. The DC/DC converter is always working because of the internal SRAM which holds the pictures. I just had to hook the microcontroller to the internal camera supply.

Well, I thought the hardest part is done by developing the software and soldering the controller board. But it is more the housing to protect the camera. You can not imagine what kind of requirements have to be fulfilled if you want to equip your cat with a camera. I built a small housing out of plastic plates and put it on the collar of the cat for evaluation purpose. This housing was last seen as the cat walked out of the door… Probably the wires I used for attaching were not strong enough. Or someone released the cat from the interesting looking piece.

For the second try I used the plastic package of a child toy (Kinderueberraschung), put a stone in it for loading it with some weight and attached it again to the cat collar. This time the part returned – dirty and scratched outside, water inside. What the hell is the cat doing !? This raised the requirements for the camera protective housing a lot

Big moment no. 1: attach the collar with the camera to the cat. The reaction was not very happy but finally accepted. Reality check passed 🙂

This is my favorite home engineering project. The concept is great. The explanation of the technology is great. The adjustment to real life situations is great. The end result (the photos) is great. This wins the non-existent Curious Cat Cool Contraption award. If someone doesn’t start selling prefabricated cat cameras I will be very surprised (if I was more enterprising I would do it myself). Maybe J. Perthold will, in any event he should inspire many to try making their own.

Using Viruses to Construct Electrodes and More

She harnesses viruses to make things

Manufacturing was once the province of human hands, then of machines. Angela Belcher, professor of materials science and engineering and biological engineering at MIT, has pushed manufacturing in another, much smaller, direction: Her lab has genetically engineered viruses that can construct useful objects like electrodes and wires.

Her lab employed this method to form an electrode that can be used in a lithium ion battery like the rechargeable ones used in electronics. The result looks like an innocuous length of celluloid tape, the sort you could use to wrap a package.

“It’s self-assembled,” says Belcher. “The viruses make these materials at room temperature.” So there’s little pollution.

Belcher hopes to be making prototypes within the next two years. “Actual devices are five to 10 years off.”

Interview of Steve Wozniak

Excellent interview of Steve Wozniak from Founders at Work: Stories of Startups’ Early Days by Jessica Livingston, to be published in a few months.

I said, “No, I’m never going to leave Hewlett-Packard. It’s my job for life. It’s the best company because it’s so good to engineers.” It really treated us like we were a community and family, and everyone cared about everyone else. Engineers—bottom of the org chart people—could come up with the ideas that would be the next hot products for the company. Everything was open to thought, discussion and innovation. So I would never leave Hewlett-Packard. I was going to be an engineer for life there.

Sounds like Google today, see: How Google Works focused on engineering and Enginners at Google Make Decisions.

Top degree for S&P 500 CEOs? Engineering

See more recent post with data from 2005-2009: S&P 500 CEO’s: Engineers Stay at the Top

The most common undergraduate degree for CEO’s of Fortune 500 companies is Engineering: with 20% of all CEOs (from 2005 CEO Study: A Statistical Snapshot of Leading CEOs

Another interesting point from the report (at least to those of us who grew up in Madison with a father who taught at the University of Wisconsin (teaching Chemical Engineering, Industrial Engineering and Statistics, in my father’s case, by the way):

For the second year in a row, the University of Wisconsin joins Harvard as the most common undergraduate university attended by S&P 500 CEOs. Prior to 2004, Harvard alone was the most common school attended.
