List of engineering blogs from top companies – Twitter, Facebook, Airbnb, Linkedin, Foursquare, Tumblr

RC3. org – A list of engineering blogs

…technology trends of the past few years has been the emergence of engineering blogs. They are, mostly, a recruiting tool, but that doesn’t mean that you can’t learn a lot about how companies operating at varying levels of maturity and scale go about their business.

A few examples:

  • Building a recommendation engine, foursquare style explains the computational shortcuts you can take when you’re dealing with a lot of data.
  • Creating an interface for geofences is a look at how Flickr built an interesting feature.

Visions of Earth 2012 – stunning global photo gallery

Here is a breathtaking photo gallery from National Geographic – Visions of Earth 2012

Why I chose these shots:

  • It’s summer and I feel like this orangutan (loungin!)
  • Our neighborhood now has raccoons, two of them. They are weird too. Last week, I was writing outside and they popped up on the fence, right in front of the dog, and started cooing at me. Like they wanted milk or something. Then the other night, like 3am, there was an epic battle on a neighbor’s tree between the raccoon’s and possibly the possum who used to patrol this territory. There was all sorts of scratching, hissing, branches shaking, and yelling to wake us up.
  • Just to show you how awe-inspiring the gallery is – Dolomites, Italy (part of the Alps).

The most travelled man on Earth…ever – Gunther Holtorf’s 23-year journey

This is an amazing journey Across Africa, Asia, South/North America, including North Korea and Cuba!

Watch it, you won’t be disappointed.

 

 

Back in 1989, as the Berlin Wall fell, Gunther Holtorf and his wife Christine set out on what was meant to be an 18-month tour of Africa in their Mercedes Benz G Wagen. Now, with more than 800,000km (500,000 miles) on the clock, Gunther is still going. – BBC News

Where do America’s biggest banks make their money?

Most people know the traditional banking model, if only from George Bailey in It’s A Wonderful Life.

In simplified form: A bank takes deposits from savers, and pays them a low interest rate. Then it lends that money out to borrowers at a higher interest rate. The bank’s profits come from the difference between the rates.

 

Charming…but far from the truth for the modern bank. An article from NPR’s Planet Money looked into JPMorgan Chase, the largest bank in America, and found they do much more than that.

The two most important ‘extra’ activities are charging fees and the outright investing of their own money. Here is how it breaks down:

  • $48 billion – interest from loans
  • $35 billion – fees
  • $11.5 billion – trading

A little less than half of the bank’s revenue comes from non-traditional banking activities (fees, trading). Not so bad, especially with trading accounting for so little. Remember, one of the root causes of the financial crisis was all the big banks exploding their trading. When the market collapsed so did they, but were “too big to fail” and we had to bail them out.

Suffice it to say that banking with deposits and loans is very hard (George Bailey nearly went under), add in too much trading and banks become very unstable.

Amazing Species: Sea Slug – swallows bubbles, eats stinging cells

 

Sea Slugs of Hawaii

This little guy is called Glaucus Atlanticus. It is a species of sea slug that grows to around 35 mm. They float partially by means of an air bubble, which they swallow and store in their gastric cavity. They also have a rather unique defence mechanism – they store the nematocysts produced by jellyfish (their prey) in their own tissues to protect against predators.

Future of clean energy in California – part renewable, part natural gas, and lots of changes

Living in California means power plants on the beach. It’s a fact of life driving up and down the coast. When you enter Los Angeles driving north there is a line of smokestacks so dense that some refer to it as “the apocalyptic city of the future.” Then as you enter San Diego driving south you pass along the “Betty Boop monument,” two giant domes with a small cap on top, which are the two nuclear generators of San Onofre.

They are all facing an uncertain future as California state law requires 33% renewable energy by 2020. Plus, an “upgrade law” which establishes higher standards for air pollution and environmental impact. That second law is the most far-reaching, and somewhat sneaky, because it directly attacks the existing power plants.

It forces all the existing plants to pay for expensive upgrades or be decommissioned, and many will be decommissioned.

As that happens you can see the future of energy in California start to take shape. 1 out of every 3 plants will be shut down and replaced by renewable energy. Another one-third will be upgraded, and the final third will be a mix. For Southern California that could mean nuclear energy, but it is more likely to be several lower-emission natural gas plants.

There is also a hope that renewable energy can take on up to half of the energy needs by 2020, but only time will tell.

To hit this point home, my local power plant, just a few miles away, is facing the decommission or upgrade dilemma. According to the owners, AES, the plant is a critical supplier in an ideal location so it won’t be shut down. The plant, a natural gas user, will be upgraded.

The plan they have put forward involves a much more modern set-up, including: replacing the industrial smokestack profile with an office building look, using air cooling instead of water (a big win for local ocean groups), much more efficient and powerful generators, quick start capabilities (from 12 hours to 10 minutes), and a reduced emission output.

For locals, like me, this is a partial win. We get rid of the ugly smokestacks and get cleaner energy, but still have a local plant giving off emissions and using fossil fuel.

The Orange County Register did a feature on what this change means for the community and the state – H.B. to lose landmark stacks for cleaner energy project

So, that image of driving along the California coast may soon change. Maybe those industrial smokestacks will turn into windmills, parks, or knowing how the state works, new million dollar homes.

The 9 members of China’s communist party who rule the country

 

It is a great piece that shares little known facts about the Rising Tiger, like all the elites dye their hair black (usually with “jet-black pompadours”) and only go gray once they retire or are imprisoned.

Others like how leaders are chosen every 5 years at the National Congress and the preferable color of tie is red.

The last one was held in 2007, which means that we are due. The reigning group of elites, made up of 9 men, are very powerful and completely in control of this vast country. This group includes current president Hu Jintao, and his possible replacements Xi Jinping and Wang Yang.

After them are seven more individuals who each hold immense amount of power and sway. The Foreign Policy article has bios for each of them, here is one:

 

Wang Qishan

The mayor of Beijing from 2003 to 2007, Wang Qishan is currently the vice premier responsible for economic, energy, and financial affairs, serving under outgoing premier Wen. Wang’s former counterpart, former Treasury Secretary Hank Paulson, called him “decisive and inquisitive,” with a “wicked sense of humor.” The son-in-law of the late Vice Premier Yao Yilin, Wang is one of the princelings, a group of often high-ranking leaders who are the sons and daughters of top officials. Chinese political observers see princelings like Wang as more closely allied with the leadership faction of former President Jiang Zemin than that of current President Hu Jintao. Brookings’ Li thinks Wang, nicknamed “chief of the fire brigade” for his competence amid crisis, is almost certain to obtain a seat on the Standing Committee.

 

The rest of them are just as interesting, keep reading – Meet China’s Next Leaders

Wind is cheaper than coal? — Fact checking this statement

The other day I heard in passing, “wind is now cheaper than coal.” If true, this symbolizes the holy grail of renewable energy. It would mean that a turning point for not only cleaner energy, but global warming, climate change, pollution, foreign oil dependence, and more.

To fact check this, I pulled up the top 20 results from Google and narrowed them down to the below articles (most were duplicates pointing at these 5 stories).

Not at all definitive but it does give you an idea of the state of the industry. Just keep in mind that the prices may or may not include subsidies or tax breaks, which can drastically change the costs quoted below.

 

Jul 2012 – In India, wind is cheaper than coal in Indi (w/out subsidies) (Bloomberg Business)

The cost of wind power has dropped below the price of coal-fired energy in parts of India for the first time as improved turbine technology (from GE) and rising fossil-fuel prices boost its competitiveness, Greenko Group Plc (GKO) said.

 

Mar 2012 – In Michigan wind is cheaper than coal (American Wind Energy Assoc.)

The Michigan Public Service Commission (PSC) recently issued a report that finds that electricity generated from renewable energy sources, at an average cost of $91 per megawatt-hour (9.1 cents/kilowatt-hour), is almost one-third cheaper than the cost of electricity from a new coal-fired power plant ($133 per MWh, or 13.3 cents/kWh).

Further, the report notes, “The actual cost of renewable energy contracts submitted to the Commission to date shows a downward pricing trend.

 

Feb 2012 – In California, prices doubled in the first decade of 21st century, since 2011 are dropping to parity with natural gas (SF Gate)

The price of renewable power contracts signed by California utilities more than doubled from 2003 through 2011 but has now started to plunge…

The cost of buying electricity from a new natural gas power plant…(in 2011) ranged from 7.5 cents per kilowatt hour to 12 cents per kilowatt hour, depending on the length of the contract…The cost of renewable power from wind and solar facilities averaged between 8 and 9 cents per kilowatt hour.

 

Nov 2011 – Investigation of Bill Clinton’s claim that wind/solar are cheaper than nuclear (Politifact)

  • Conventional Coal – 94.8 (dollars/MWh)
  • Wind – Onshore – 97
  • Nuclear – 113.9
  • Solar – Photovoltaic – 210.7
  • Wind – Offshore – 243.2
  • Solar – Thermal – 311.8

Nov 2011 – Google retires its initiative RE

It’s not clear here if Google feels this is already won and moving on, or if they have had enough and are quitting. One thing is certain, Google invested nearly a billion dollars ($850 million) in renewable energy last year.

This initiative was developed as an effort to drive down the cost of renewable energy, with an RE<C engineering team focused on researching improvements to solar power technology. At this point, other institutions are better positioned than Google to take this research to the next level. So we’ve published our results to help others in the field continue to advance the state of power tower technology, and we’ve closed our efforts.

Happy 10th Birthday to Daring Fireball – a role model for this blog

Happy 10th birthday, John Gruber, of the curation blog, Daring Fireball. A role model of mine in both style and eccentricity. I hope to one day achieve your level of excellence and also prove to the world that being a blogger can provide a happy life for me and my family.

A fellow writer, Robinson Meyer of The Atlantic, also pays tribute to Daring Fireball:

This, from a 2008 interview, is still a better articulation of the joy of reading great sequential writing than you’ll regularly find:

Gruber: I’ve always enjoyed the way that with good columnists, it’s not just that their individual articles stand on their own, but that there’s something greater than the sum of the parts when you follow them as a regular reader.

And he can still better articulate what’s fun and compelling about link-sharing (which he’s been doing since before we deemed it curation) than anyone. From the same interview:

Gruber: There’s a certain pace and rhythm to what I’m going for [when I share links], a mix of the technical, the artful, the thoughtful, and the absurd. In the same way that I strive to achieve a certain voice in my prose, as a writer, I strive for a certain voice with regard to what I link to. No single item I post to the Linked List is all that important. It’s the mix, the gestalt of an entire day’s worth taken together, that matters to me.
