Questions from someone looking for an engineering job @ Google

How soon I can apply for other positions at Google if am rejected for a particular position?

There's no limitation. However, Google has a long institutional memory. If you did badly for reasons of cultural fit, it is unlikely that any subsequent application will be successful. If your first set of interviewers are credible, it will take an extremely strong referral notice from an employee who was a previous colleague to give you another chance.

What's the total interview duration in general?

45 minutes each, 5-8 interviewers (including phone interviews)

I am not a spontanious person in nature and hence chances are likely that I don't do good in interviews. But am really excellent on the job. What's your advice in my situation during interview?

Practice, practice, practice. Get a few friends to do mock interviews. Or try an alternate way of getting into google, through one of the many programming contests we sponsor, for instance.

What's the good reference you recommend to get the basics of computer science(I may not know all the fundamentals that I learn thro' my job).

Two classic textbooks: If you can read both books and do the exercises easily, then you are probably qualified. (If you click through and read the reviews, you'll notice that the first SICP reviewer is Peter Norvig, a Google director)

The perils of having a blog

Someone's been spamming folks advertising for jobs at Google in my name, using my e-mail address. This is annoying as heck, and I hope I don't end up on too many spam lists as a result. The perils of having an on-line identity are certainly high now compared to when I first had a web-site back in 1993.

I could certainly take down the blog instead. What do you think?
Take that, Seattle-ites

Sorry, Scarlet, your misfortune is my good weather. We had crummy weather all winter last year (ok, crummy by California standards) --- even Bike to Work day in May got rained out. Now let us Californians have the weather we pay our state taxes for! :)

One things is for sure is that the pacnw is in for a much wetter winter compared to last year as it started raining there two weeks ago and don't see any let up in sight. It will take a very strong wave over the top of this ridge to be able to bring any change in the weather this far south.
Scott Burns on Retirement

I definitely disagree with Scott Burns on politics (especially his views on Social Security), but the man does write a great financial column:

Work, Part 2: Men need to pay more attention to women. They're a lot more adaptable than we are.

My wife retired this year, kind of, and she is as happy as I've ever seen her. She works for good causes and is useful. But the money meter is no longer running.

The weaker sex (men, if there was any doubt) would live longer if we could only see life as a cooperative festival rather than a competitive struggle.

Work, play and opportunity cost: The greatest dilemma of continuing to work is fairly subtle, something you don't think about at 30: Every hour spent working is an hour lost to play.

Money: In the big picture, it is less important, not more important.

Some will criticize this statement, noting that it's easy to say money isn't important when you have plenty of it.

But one of the true blessings of being older is that objects don't mean much. Friends do. Objects cost money. Friendship is free. It comes from the unlimited currency of the heart

Investing: But 40 years of investing has taught me that rented brains seldom help us build our nest eggs. Rented brains feel a deep spiritual need to build 20,000-square-foot log cabins in Jackson Hole with the return on our money.

Headphones

Piaw's reviews of headphones for the ipod

First of all, forget the earbuds that come with the ipod. They are terrible, and not at all what I would consider either comfortable or practical. Note that despite my mention of helmet compatibility in these headphones I neither endorse nor encourage the use of headphones while riding your bicycle in traffic!!

Sennheiser PX 100 Headphones

I paid about $38 for these when they went on sale a while back on Amazon.com, and they are great! Plugged directly into the ipod, the sound is neutral, and almost as good as my Sennheiser 600s with an Airhead amplifier. They fold up neatly into a box the size of a spectacle case, and are very comfortable to wear on hikes as long as 4 hours or so. These are my favorite headphones for hiking or general walking around.

Koss KSC 75

These are the ones to get if you can't stand having a headband over your head, or have to wear a helmet while listening to your music. They fit nicely on the helmet exterior, and despite the loose feeling connection, don't fall off easily. They sound great for $14, and while not as nice as the PX 100s, are cheap enough that if you destroy them you won't feel guilty about them. The plug is also a very ipod friendly 90-degree plug, which isn't true for the Sennheiser.

Koss Sport Pro

At $22, these are disappointing. I bought them when I gave my mom my KSC 75s, and they do work under your helmet, but the headband isn't super-comfortable under the helmet. (You can tilt the headband backwards so it doesn't interfere with the helmet) They do fold up neatly into a nice compact package and clamp nicely to your head so they don't allow as much road noise as the KSC 75s, but despite that they still do not sound as nice as the KSC 75s and are a far cry from the Sennheiser PX 100s. I only recommend these if you've already tried the KSCs and found that they don't fit your ears for one reason or another.

More riding

Up Old La Honda, down 84, up Alpine road, down Page Mill. 50 miles, and 1400m of climbing (4593 feet). It was gorgeous, of course.

Thoughts from the ride: it's hard to make friends as you get older. For one thing, everyone's incredibly busy, with kids, with work, or with their existing friends. The days of saying, "Can you come out and play?" and then spending the day hanging out and doing stuff are perhaps one of the luxuries we don't get when we're adults. But when you do get a chance to do so, it's a lot of fun, and really something to treasure.

I thought of us
So hard to talk these days
Did we change
Or were we strangers all along
Tell me what caused us to turn away

Scott Burns predicts a recession

And I believe him. Together with the imminent collapse of the housing bubble, we're going to see some tough times:


... Skeptics should consider this brief list:

•The rising cost of gasoline. With the typical household consuming about 1,000 gallons a year, an increase from $1.50 a gallon to $3 meant a purchasing-power loss of $1,500.

•Rate increases for electricity and natural gas.

•Rising medical co-pays and other out-of-pocket expenses for health care, plus rising employee health insurance premium costs. Premium costs were up 10 percent in 2004 alone.

Another way to see the same thing is to examine wage gains.

In 2004, the average weekly earnings of private nonagricultural workers rose only 2.2 percent. The consumer price index rose 3.3 percent over the same period.

To the best of our knowledge interviews Margaret Atwood

They interview her about her latest book, Oryx and Crake. Scarlet should listen to this because at one point Margaret Atwood denies her existence. She says, "Girls/women don't spend hours and hours in front of the computer playing strategy games." Scarlet is much more capable of doing that than I am, though I'm sure that Evan has cut into her gaming significantly. Yet I suspect that Scarlet will not be the kind of person who would consider video games to be rotting her kids' brains.

Review: Freakonomics

Freakonomics

Yes, I'm late to the party. Levitt & Dubner actually visited Google a few months ago, but by then I already had the book on the queue at the Santa Clara County Library. It's a great read, covering everything from crime to sumo wrestling and the defeat of the Ku Klux Klan by Superman (a true story!). Highly recommended!


Recall for a moment the two boys, one white and one black, who were described in chapter 5. The white boy who grew up outside Chicago had smart, solid encouraging, loving parents who stressed education and family. The black boy from Daytona Beach was abandoned by his mother, was beaten by his father, and had become a full-fledged ganster by his teens. So what became of the two boys?

The second child, now twenty-seven years old, is Roland G. Fryer Jr., the Harvard economist studying black underachievement.

The white child also made it to Harvard. But soon after, things went badly for him. His name is Ted Kaczynski.

Hidden Order: The Economics of Everyday Life

An excellent book covering what's essentially "Economics 101" for non-economists or for people who skipped that class in college (or high school). It unfortunately doesn't cover some of the complexities that are in typical economics textbooks (such as network externalities and increasing returns to scale), but given the limited space, that's understandable.

Recommended if you're not already an economics junkie.

Gladwell came to give a talk at Google, which prompted me to mine his web-site for more good stuff. The Talent Myth is great reading, and has a lot of very good lessons for smart people, who tend to overvalue smartness.

Republicans are Evil, part III

Well, the U.S. government has to get money from somewhere. As a two-term former Republican senator from Florida, where do you suggest we get money from?

What money?

The money to run this country.

We'll borrow it.

<>I never understand where all this money comes from. When the president says we need another $200 billion for Katrina repairs, does he just go and borrow it from the Saudis?

In a sense, we do. Maybe the Chinese.

Is that fair to our children? If we keep borrowing at this level, won't the Arabs or the Chinese eventually own this country?

I am not worried about that. We are a huge country producing enormous assets day in and day out. We have great strength, and we have always adjusted to difficulties that faced us, and we will continue to do so.

List of 2005 Book Reviews

I've decided that it's a good idea to put links to all my book reviews in one post, for my own needs. They're not listed in any particular order, though what I've done is for series of books, to place the books in series order (i.e., the order in which they're intended to be read) Having this list will let me select books of the year (at the end of each year), and also provide a handy link off to the right so new readers can have a collection to jump to.

The best books of 2005 get special mention in their own post.

Fiction
Non-Fiction
Graphic Novels (AKA comic books)
The John Varley Reader

John Varley's recent books have been unfortunately lightweight, though still fun to read. This collection of his short stories, however, shows off how versatile he is, and how far ahead of his time he was. Nearly every story is exciting and a good read, and you can see the themes showing up in his "8 worlds" milleu. Highly recommended!
Ran into Neil & Julie Hunt at the top of Black Mountain today. The hike itself took Shyam and I 1:50 minutes to the top (Neil & Julie did it in 1:30, which goes to show that the decade between Pure Software and Netflix has not slowed him down at all). Neil is the Chief Product Officer at Netflix and as the former VP of Engineering built most of the software that runs the site. He happily showed me his new toy --- a weather station at his vacation home that regularly reports the current conditions over the net to his blackberry.

A ride to the coast

Leaving my house around 9:15am, I climbed up Robleda and Taaffe in the fog, pausing to take off my jacket at the junction at Page Mill road, where past the Moody intersection the fog lifted and crepuscular beams showered me with sunlight through the leaves. I took the climb up Page Mill road at an easy pace, enjoying the sound of the crickets and the complete lack of traffic at this early hour (a total of 4 cars passed me on the entire climb). As I climbed, the road granted me views of Silicon Valley covered by a blanket of low clouds.

At the top of Page Mill road I crossed over to Alpine road and began a fast descent, where what should have been Ocean views were obscured also by low clouds at the fog, even though it was sunny where I was. The descent into the redwoods was exhilarating as usual, with the pungent smell of trees in the air. At 84, I made the descent down to San Gregorio, a boring rolling stretch of road that did not provide much to recommend it.

At San Gregorio, I eschewed at stop at the store and turned right along Stage road, which took me up to Highway 1 where a fog shrouded descent towards Half-Moon Bay made me paranoid. I did make the turn onto Tunitas Creek road with no incident, and there was over taken by some Diablo Cyclists touring club members who passed me with vim. As the 3rd person passed me, I caught his wheel and we rode together for a bit and chatted. I learned that it was their twice a year visit to the area.

We rode together for a bit before I started feeling a bit hungry and stopped to eat and shed my jacket. As I got started again, two more Diablo club members caught me and I rode with them some more. These touring club members were incredibly strong and I had a hard time staying with them, and eventually was dropped despite climbing Tunitas Creek road at a pace I hardly ever attempt.

Near the top, the club gathered and we chatted. Tom, one of the club members, recognized me as an internet-bob member (well, OK, I started that mailing list but is no longer on it). I let the club go ahead and then descended Kings Mountain road with not a single vehicle behind me. At the bottom I made a turn onto Tripp road, visited Highway 84 before dropping down into Portola Valley. The sun was out at this point but the recent fog made it still cool, so I made good time to Alpine road and Arastedero road, before riding through Purissma and back to Robleda and home.

It was a good ride with 68 miles of riding and 6400 feet of climbing.

Black Mountain Hike

I hiked up Black Mountain on Sunday morning (yes, Scarlet, this is the same top of Montebello that you've ridden several times). It was a 3.5 hour round trip on foot from the base, and the views were outstanding. I had at least 80 miles of visibility, and could see all the way to San Francisco and Oakland! Well worth the trip.

I love it now that I'm in shape for hiking --- just a year or so ago, every hike would leave me worn out the rest of the day. This 9.5 mile hike left me able to read 2 books and work a bit on a new wheel.
The Future of Success, by Robert Reich

This book starts out badly, pointing out things that should have been obvious to anyone who hasn't been living in a cave for the last few years. Reich points out that the winner take all society seems to have gotten more and more prevelant, and Americans seem to be running harder and harder just to stand still.

Fortunately, he gets better! He analyzes the cause of the increasing disparity between classes (the stakes are higher --- each 5% of success compared to the median draws much more proportionate income and pieces of the good life than it used to, and each 5% of failure contributes to much less money than it used to), and points out that it's simply not true that the culture of students have not gotten more selfish and materialistic. That it's not true that Americans are addicted to work and are workaholics (Americans now work even more hours than the Japanese!) --- but it's a rational reaction to the current state of affairs, where cut-throat competition amongst employees, companies, and fellow students is a result of the increased uncertainty in the marketplace --- your pay is now much more variable than before, while your expenses are still fixed, so you're compelled to work as hard as you possibly can whenever you have an opportunity.

His policy proposals are also quite reasonable: wage insurance, for instance, is an excellent idea --- if your job gets outsourced, you can half the difference between your old job and your new job, which gives you a cushion to get retrained. This is too good an idea and will never get passed while the Republicans are in charge, but I definitely consider it a solution to a major cause of bright students deciding to abandon engineering and science because of the fear that all the technical jobs are going to India and China.

Let me quote one passage that demonstrates that Robert Reich gets it, while many science and engineering educators and other smart people don't:
The stars of Wall Street, Silicon Valley, and Hollywood are coming to resemble Professional athletes who can count on no more than ten to fifteen years before losing their competitive edge. Twentysomething software engineers are in great demand; when they're over forty, they're over the hill. Surveys show that six years after graduating with a degree in computer science, 60 percent are working as software programmers; after twnety years, only 19 percent are still at it. This largely explains why high entry salaries and generous signing bonuses are still not enough to entice greater numbers of undergraduates into the field. They know how quickly they'll become obsolete
The Drawing of the Dark, by Tim Powers

I first tried to read The Anubis Gates in high school, and didn't get very far. However, 5 years ago, I found a copy of The Stress of Her Regard at the Santa Clara County Library and found it to be an incredibly good read, combining some of my favorite themes into a nice historical fantasy package.

The Drawing of the Dark, sad to say, does not rise to the heights of The Stress of Her Regard. It's light hearted, easy going, and one can guess the identity of the protagonist long before he is unveiled for the reader (or even to himself). It breaks no new ground, and is light entertainment for about 2 or 3 hours. Recommended when you don't want to use your brain too much.

"How old are you, Brian? You ought to nkow by now that something always breaks up love affairs unless both parties are willing to compromise themselves. And that compromising is harder to do the older and less flexible and more independent you are. It just isn't in you, Brian. You could no more get married now than you could become a priest, or a sculptor, or a greengrocer."

Iron Sunrise, Charles Stross

Stross is an excellent plotter, but with not much of a voice. For the first 6 chapters or so I thought I was reading something by Stephen Baxter. The characters aren't great, but the concepts are brilliant, and of course, the little nods towards Computer Scientists. He ends the novel with room for a sequel which would not be unwelcomed.

The UNI headquarters campus hadn't changed visibly in Rachel's absence---the same neoclassical glass-and-steel skyscraper, looming over old Geneva's stone arteries and quaint domes, the same big statues of founds Otto Von Bismarck and Tim Berners-Lee sitting out front in the plaza...

Piaw's Home Page Revived

It's quite a bit worse for wear, unfortunately, old pictures are no longer up --- I have to dig through some old Kodak CDs to recover some of that stuff), and of course, it's several years out of date. It did have quite a bit of interesting content, though, so I'll keep it up for a bit, and will eventually use it as a hub for more travel stories and other ideas that the blog format doesn't work well on.
Buffy the Soundtrack

An surprisingly good soundtrack. I do remember that some of Buffy's episodes had live bands that were quite good and thought I'd get a chance to hear some of the songs all the way through. I was right. Impressive tracks include:
  • Lucky - Bif Naked
  • Virgin State Of Mind - K's Choice
  • Already Met You - Superfine
  • Nothing But You - Kim Ferron
  • It Doesn't Matter - Alison Krauss & Union Station
  • Wild Horses - The Sundays
  • Pain (Slayer Mix) - Four Star Mary
  • Charge - Splendid
  • Close Your Eyes (Buffy/Angel Love Theme) - Christophe Beck
Money well spent. I definitely am hunting down some of the artists' other albums and seeing if their other music is just as good.

A Deepness In The Sky

The prequel to A Fire Upon The Deep. This time, the aliens aren't as beautifully imaginative or interesting, but the human characters are much better, as are the (very human) villains. The ending wraps up a little too pat, with everyone paired off, but there are Shakespeare plays that do that too, so I suppose it's in the grand tradition of story-tellers.

Religious Socities are worse off

Many liberal Christians and believers of other faiths hold that religious belief is socially beneficial, believing that it helps to lower rates of violent crime, murder, suicide, sexual promiscuity and abortion. The benefits of religious belief to a society have been described as its “spiritual capital”. But the study claims that the devotion of many in the US may actually contribute to its ills.

The paper, published in the Journal of Religion and Society, a US academic journal, reports: “Many Americans agree that their churchgoing nation is an exceptional, God-blessed, shining city on the hill that stands as an impressive example for an increasingly sceptical world.

“In general, higher rates of belief in and worship of a creator correlate with higher rates of homicide, juvenile and early adult mortality, STD infection rates, teen pregnancy and abortion in the prosperous democracies.

Adam's Curse, by Bryan Sykes

Sykes is a rare bird: an accomplished scientist who can write for the layman. He describes results of recent research into the history and future of the Y chromosome, which is special: unlike the other chromosomes in the body, it does not get to participate in recombination, thereby it is the chromosome that accumulates errors and is now excessively specialized. The book is an exciting read, and a real pleasure --- easily one of the best science books of the year for me. His description is clear even for someone who's not a geneticist.

If the book has a fault, it is that he claims that sexual selection is directly responsible for many of the ills today --- women are attracted to powerful men (or in the case of Genghis Khan, who has 16 million modern men carrying his Y chromosome, were forced into bearing the children of powerful men), and power as well as money are hereditary in most patriarchical society, thereby increasing the amount of greed and avarice and rapacious treatment of the environment. In reality, however, even if women were the only gender in the population, the desire to achieve better environments for one's offspring is just as strong in the X chromosome, which imply to me that the world would be in no better shape if only women existed. I've certainly met enough short-sighted and greedy women to realize that those traits are not entirely driven by testosterone.

If you're going to buy this book, buy the updated paperback version. I read the older hardcover, but it should be the same material.

The Cheating of America, Charles Lewis

A so-so book about tax evasion. Rather than presenting a coherent case about tax evasion, how it happens, and what legislation went into making it possible, the book is just one series of stories after another about successful tax evasion. Sure, it makes your blood boil, but after the umpteenth story, you feel kinda defeated instead of angry.

Read Perfectly Legal instead, a much better book about the same topic.

A Distant Soil 2: Ascendant, by Colleen Doran

The pace finally picks up and the story coheres. Doran steers away carefully from many adult issues, however, so the book never quite gets to the level of maturity I've seen from more seasoned writers. Again, something you should check out from the library but not buy.
Orbiter, Warren Ellis and Colleen Doran

A comic book that works too hard to inspire. I'm a science geek and I definitely believe that man should find a way to go to the stars. Having said that, glorifying the space shuttle is not the way to go. There are lots of other more innovative approaches (such as the Space Elevator) that deserve consideration that NASA's budget wouldn't allow if it was all spent taking care of the shuttle.
The Search, by John Battelle

I was eager to read this book, since I joined Google just 2 years ago, when a lot of the history had already happened. (Amongst my big questions were: what happened during the experiment with traditional engineering managers?) Unfortunately, Battelle did not get that much access to Google, and hence was unable to write a complete account. Regardless, this book is worth reading, and since it is relatively short, won't take up too much of your time.

It remains for a Google old-timer to write the definitive book about Google's early history.

Eric Schmidt comes across as a man who is comfortable in his own skin. He's been a CEO or top executive for more than two decades, having been CTO at Sun, where he mad his first small fortune, then CEO of Novell, a major IT company, where he made his second. He knows when to smile, when to be gracious, when to keep quiet, and when to answer a difficult question with self-effacing acknowledgment. He brandishes subtle and humorous double entendres like a Japanese swordsman, a trait that almost offsets the superiority complex he shares with nearly every talented engineer in the Valley.

Despite these skills, one gets the impression that Eric Schmidt has yet to get entirely comfortable with his place at Google, his title as CEO notwithstanding...
My 20% project makes the New York Times!

Sure, it's a short piece, and most of it quotes Hal Varian, who's much more of an expert on prediction markets than I ever will be, but WOOHOO! One would think that after 14 years in the industry, I would have gotten over something like this (after all, Mpath, HearMe, and Quake all got in the news quite a bit), but it's different when it's your personal 20% project, as opposed to something that's part of a corporate charter. (Though the Mpath will always be dear to my heart)

OK, now that I've hiked half-dome, I don't have to do it again. It was crowded. The hike was long and towards the end more than a little painful. I'm still sore 24 hours later (though I'll admit I'm not in great hiking shape). It might be more fun when it's less crowded, but this hike reminded me why I always do my trips from Tuoloumne Meadows and almost never visit Yosemite Valley any more.
