Server farms go solar

Friday, October 5th, 2007

Server farms go solar:

Massive data centers are vital to the economy. They are also notorious power hogs. If their numbers keep growing at the expected rate, the United States alone will need nearly a dozen new power plants by 2011 just to keep the data flowing, according to the Environmental Protection Agency.

That’s why a small server-farm company called AISO.net (for “affordable Internet services online”) has gone completely off the grid. Located 80 miles southeast of Los Angeles in the desert hamlet of Romoland, AISO.net has flanked its 2,000-square-foot building with two banks of ground-mounted solar panels, which generate 12 kilowatts of electricity. Batteries store the juice for nighttime operation.

To slash energy consumption, AISO.net switched from 120 individual servers to four IBM blades running virtualization software that lets one computer do the work of multiple machines. The cooling system cranks up for only about 10 minutes an hour, and when the outside temperature drops to 60 degrees, air is sucked into the building to cool the servers. Solar tubes built into the roof illuminate the facility’s interior.

The service is attracting plenty of eco-conscious clients. Al Gore’s Live Earth concerts were webcast on AISO.net’s servers in July. And San Diego startup GreenestHost is reselling AISO.net’s services to mom-and-pop website operators who want to go carbon-neutral. “Small data centers could easily start to adapt and make changes like this,” says AISO.net co-founder Phil Nail, who claims the project cost about $100,000.

His monthly electric bills, once as high as $3,000, have dropped to zero. Larger data centers can’t match that. But Sun Microsystems did recently slash power consumption 61 percent by consolidating its Silicon Valley servers into a single state-of-the-art facility. And IBM BladeCenter VP Alex Yost sees growing demand for energy-efficient servers like the ones AISO.net uses. “It’s an enormous economic opportunity,” he says.

The project cost $100,000, but the real question is, How much more did this data center cost than the alternative? That’s the number we need to compare against saving $3,000 per month.

The kopy kat kids

Friday, October 5th, 2007

Robert Levine of Business 2.0 calls them the kopy kat kids:

The Samwer brothers never been shy about borrowing ideas. The first company the Cologne-born trio founded was a German-language version of eBay. Later, as venture capitalists, they invested in European startups that were direct knockoffs of YouTube, Facebook, and Twitter.

The brothers Samwer (Alexander, 36; Oliver, 34; and Mark, 32) are unapologetic about their fast-follower tactics — mostly because they work. Alando.de, the eBay clone they launched in January 1999, was snapped up five months later by eBay itself — for a cool $50 million. And they had early money in StudiVZ, a two-year-old European Facebook clone that reportedly fetched more than $100 million when it sold to publishing company Holtzbrinck earlier this year.

Critical Chain 6

Monday, October 1st, 2007

The folks of the Theory of Constraints Center have a little project game to demonstrate how task and resource dependencies combine with a bit of unpredictability to create a cascade effect.

Imagine you have a simple project with five tasks, each of which is expected to take seven days. Since Tasks A and B can be done in parallel, and Tasks C and D can be done in parallel, we should expect the whole project to be done in 21 days.



But those five tasks don’t take exactly seven days each — they take roughly seven days each — and for our little game we roll a pair of dice for each task to represent that uncertainty.

Let’s say our random task durations come out as follows:

Task A — 5 days
Task B — 9
Task C — 3
Task D — 8
Task E — 6

Then our whole project is done in 23 days, not 21.


Hey, that’s not so bad, right? You roll high sometimes; you roll low sometimes. We expected 21, but it came out 23.

But let’s take another look. Our average roll was just 6.2 — less than 7. We rolled better than average, yet our total was worse than average. In fact, if we look at each color — I’m assuming each color represents a different resource dependency — then each color scores better than average too.

Delays accumulate, while advances do not.

Critical Chain 5

Saturday, September 29th, 2007

It has been a while since I last discussed Eli Goldratt’s Critical Chain and project management, but there is one more element to Critical Chain Project Management that I haven’t touched on.

Critical-path analysis assumes that a task is either dependent on another, or it’s not.



But what if two tasks require the same limited resource? What if they require the same expert’s time, or the same expensive piece of machinery? The two tasks aren’t dependent on one another, but they can’t be performed in parallel.



Suddenly our wonderful critical-path analysis goes out the window, and we have to tinker with the schedule until our resource isn’t in two places at once.



With a toy problem, this is easy enough to do by inspection. With a larger program, let a computer do the work.

Of course, if you don’t have this all plotted out ahead of time, you find out the hard way that Task B is wildly behind schedule, and that your critical path has shifted from Tasks C and F to Tasks B and E.

It’s no wonder why project leaders build a lot of safety into their schedules…

Will A Google Phone Change The Game?

Friday, September 28th, 2007

BusinessWeek asks, Will A Google Phone Change The Game?

Imagine your cellphone as a mini marketing machine. As you head into your car after dinner, a text alert pops onto the screen of your handset announcing the 9 p.m. lineup at a nearby cineplex. You choose the Jodi Foster flick The Brave One and a promo video for the next Warner Bros. release, a George Clooney movie, starts running. Afterward, more text appears, prompting you to launch the phone’s Web browser so that you can click through to buy the movie’s ringtones and wallpaper.

That kind of 24/7 advertising engagement–on a phone, no less–may sound like a nightmare. But what if you could determine the kinds of products you get pitched? Or, when your flight gets canceled in a faraway airport, text messages pop up for the best hotel deals in town? No random insurance ads or airline deals for trips to places you never visit. Best of all: Watch or read the custom ads, and your phone minutes are free.

For big cell carriers, that’s the real nightmare.

Biodiesel Boom heading toward Wall Street

Thursday, September 27th, 2007

With a push from government subsidies, there’s a Biodiesel Boom heading toward Wall Street:

It’s not hard to see why. Biodiesel is 30 percent more fuel-efficient than gasoline, which in turn is 30 percent more efficient than ethanol. And while most ethanol produced in the United States comes from a single feedstock — corn — biodiesel has many sources: the oil of seed plants, such as soy and canola, french-fry grease and animal fat. That means the market can weather a price increase in any one raw material. Solazyme, a South San Francisco biotech firm, has even started making biodiesel from genetically modified algae.

Better yet, biodiesel can be manufactured in large quantities today — unlike fuels such as hydrogen. Total production shot up from 25 million gallons in 2004 to 250 million last year. Nearly 100 new plants are now under construction; even Chevron has joined in, cutting the ribbon on a 20-million-gallon plant in Galveston, Texas, in May.

The biggest player in the biodiesel market is Renewable Energy Group, an offshoot of a 3,000-member Iowa farm cooperative. REG accounts for 27 percent of U.S. biodiesel production and, thanks to its relationship with the soy growers, says it can increase its total capacity to 340 million gallons by the end of 2008. The company sells branded SoyPower fuel through a nationwide network of stations, some operated by grocery giant Safeway. REG should be the first biodiesel company to hit Wall Street, having filed for an IPO in July. But REG won’t be the last: Also mulling a stock offering is Seattle-based Imperium Renewables, founded three years ago by former commercial-jet pilot John Plaza. Imperium operates the largest U.S. biodiesel plant and plans to cut a production deal with Washington’s canola farmers.

For all that production capacity, biodiesel is still an infant industry — it currently accounts for less than 0.5 percent of the total U.S. diesel-fuel market. So there will likely be plenty more REGs and Imperiums. “It’s such an entrepreneurial success story,” says Jenna Higgins, communications director at the National Biodiesel Board, a trade association. “Most of the companies out there are small businesses. There really aren’t any traditional paths to success.”

Take Philadelphia-based Fry-o-Diesel, founded by Yale business graduate Nadia Adawi. The startup has a patent pending on a process it developed to make fuel from trap grease, which restaurants currently pay to have hauled off. An estimated 495 million gallons of trap grease gets trashed every year. “We’re working with something that’s essentially a pollutant,” Adawi says. “But it makes a great fuel.” She is currently talking to investors and hopes to build a 3-million-gallon plant in 2008.

Adawi is in good company. The past few months have seen plenty of major corporations rush to hop on the biodiesel bandwagon. Oil giant ConocoPhillips has inked a deal with Tyson Foods to make diesel out of animal fats. In July, U.S. Steel announced that it will use a 10 percent mix of biodiesel at its plant in Gary, Ind. And Berkeley-based Clif Bar has started subsidizing employees who drive biodiesel cars.

Green power

Thursday, September 27th, 2007

You may wonder why PG&E is so supportive of California’s various green power initiatives:

It also benefits from the way California regulates its utilities. Their sales are separated, or “decoupled,” from revenue, so they neither earn more by selling more energy nor lose money by promoting efficiency measures that reduce those sales.

Instead, California’s utilities make a guaranteed profit on all their investments — $2.8 billion this year for PG&E. The regulators have also approved big budgets for energy efficiency, something that has helped PG&E’s top business clients save money, while boosting PG&E’s bottom line. The $300 million PG&E set aside for energy efficiency in 2007 includes a lot of “customer education,” which often doubles as public relations for the company.

It’s such a fine line between forward-thinking and gaming the system.

Real Estate Equity Exchange

Thursday, September 27th, 2007

When you go to fund an enterprise with outside money, you have two basic options, which you can mix and match: debt, where you have to pay your lenders spelled-out payments, or equity, where you pay your shareholders their share of profits — when you have profits. Debt is inflexible. Equity is forgiving.

When you go to buy a house, you typically borrow money — you take on debt — which means you win big if your house goes up in value, and you lose big if it goes down in value. If you put 10 percent down on a $400,000 house, that means you’re putting in just $40,000 of your own money and borrowing $360,000. If the house’s value goes down 10 percent, you lose 100 percent of your initial investment — it’s worth $360,000, and you owe $360,000. If, on the other hand, it goes up 10 percent, you double your initial investment — it’s now worth $440,000, and you owe just $360,000. That’s why debt is called leverage.

Leverage is great on the upside, but most people are risk-averse, which is why I was surprised that something like a Real Estate Equity Exchange agreement wasn’t already popular:

Now a San Francisco firm called Rex & Co. (the name stands for “real estate equity exchange”) is offering a new option, known as a Rex agreement, that can be used both to draw on a home’s equity and to hedge against declining property values.

Rex gives homeowners, interest-free, a portion of their house’s market price in cash — up to 15 percent of the appraised value of the home, topping out at $300,000. In exchange, Rex gets the right to share in up to half of the future increase in the home’s value. The more homeowners are willing to let Rex cash in on future profit, the more money they get up front. If a home declines in value — and many homeowners nowadays are worried about just that — Rex shares in the loss. “It’s a way to make the equity you’ve earned more liquid,” says Rex CEO Thomas Sponholtz.

A homeowner and Rex agree on how much money the property owner is to receive, as well as the percentage of the future change in the value of the home he or she is willing to share. (The homeowner also pays back the cash advance when the property is sold.) The home’s value is assessed by a third-party appraiser.

The fact that they pay “up to 15 percent of the appraised value of the home,” but get the right to share in “up to half of the future increase in the home’s value” implies that they’re not just buying equity in the house though. It implies they’ve set up some kind of derivative that their customers won’t understand.

He’s Still Beating The House

Tuesday, September 25th, 2007

He’s Still Beating The House:

Ed Thorp’s moment is coming — again. Thorp is an investor, mathematician, and crack blackjack player whose winning system got him expelled from Reno casinos in the 1960s. Now his 1967 work, Beat the Market: A Scientific Stock Market System, has been named one of the most sought-after out-of-print books of the past year by BookFinder.com.

Beat the Market, which sells for up to $750 on Amazon.com, describes his investing system, a precursor of the Black-Scholes formula. Why is the book so hot now? Perhaps it’s rising interest in the relation between gambling and investing. Thorp also gets mentions in recent books, including Nassim Nicholas Taleb’s best-seller on probability, The Black Swan. Another attention-getter: publicity about a cigarette-pack-size computer co-invented by Thorp in the ’60s, to be exhibited next spring at Germany’s Heinz Nixdorf computer museum. “It could predict where a roulette ball would land,” he says.

Here’s Why Richard Branson Should Be Delta Airlines’ Biggest Fan

Monday, September 24th, 2007

Here’s Why Richard Branson Should Be Delta Airlines’ Biggest Fan:

Last week, Passenger X arrived at the Orlando airport with a first-class e-ticket for New York City. At the airport, the ticket machine spat out a boarding pass for a seat in the back of coach. Why?

The plane, he was told, had been “downsized” from a large jet to a smaller one. There was no first-class section on the smaller plane, so all first-class passengers had been reassigned to coach.

Passenger X asked the Delta agent why the change had been made.

“Mechanical,” he was told.

Passenger X then asked when the change had been made, and wondered why Delta hadn’t phoned or e-mailed to alert passengers to the change — which would have given them time to perhaps fly first-class on a different airline.

The Delta agent responded that she did not know when the change had been made.

Passenger X flies frequently and tries to get work done on planes, so a first-class seat is far more desirable to him than a coach seat. He was disappointed with Delta’s change, but if they’d pulled a faulty jet out of the air — well, plainly, that was a good thing.

Once past security, he asked another Delta representative about the change. This agent, too, did not know when the plane swap had been made, but agreed that Delta should have alerted its first-class passengers. “You paid for the steak but you got the hamburger,” he said. This agent couldn’t have been kinder. He even offered to give Passenger X the customer service number at Delta so that he could arrange for a refund of the difference between the first-class fare and the coach fare.

To which Passenger X said: “Thank you, and no offense, but I’d be surprised — and further disappointed — if you weren’t already doing that on your own.” In other words, should the customer who pays for the steak and gets the hamburger then have to go scrambling himself to recover the price differential?

The Delta agent, still kind, acknowledged that yes, this too was not great Delta policy, but it was the best he could do.

At the gate, a third Delta agent, perhaps even kinder than the first two, looked at Passenger X’s boarding pass and offered to put an empty seat beside him. Very thoughtful! As it turned out, this was a pretty easy task, since the plane was only about 40 percent full, which made Passenger X wonder if the first Delta agent’s story — that the original plane was pulled for “mechanical” reasons — was even true. If the smaller plane was only 40 percent full, then the larger plane was probably only 20 percent full. As such, was it possible that Delta had changed planes because of an economic reason, and not a mechanical one?

Passenger X inquired as to this possibility, and was greeted with blank stares. He did learn, however, that the flight attendants had just flown down on this same plane, from New York to Orlando. At the very least, this meant that the smaller plane had been in service for quite a few hours, certainly enough time for Delta to let its first-class passengers know that their steak was now a hamburger.

In the end, the flight was fine. Two seats in coach are just as good as one seat in first class. But if it had been a jammed-to-the-roof flight, Passenger X would have been one sad puppy.

I can confirm Passenger X’s story because Passenger X is me.

OK, that last line isn’t quite a Twilight Zone ending, but he makes his point:

Stories like this one are very good news, however, if you are in the VLJ (very light jet) business, since that is where business travelers are moving. It could also be good news for Richard Branson, who is on an all-business-class binge at the moment, and is rumored to be thinking about offering all-business-class flights in the U.S., the absence of which I have wondered about before on this blog.

The Ice Cream Ordering Sequence

Friday, September 21st, 2007

Joe Sugarman, in Triggers, uses his Ice Cream Ordering Sequence to explain a sales technique:

In the late 1950s I was working in New York selling printing equipment. One day after dinner, I decided to stop by a small ice cream parlor to have a dish of ice cream. I sat down at the counter and the waitress asked me for my order.

I requested my favorite dessert, “I’ll have a dish of chocolate ice cream with whipped cream.”

The waitress looked at me with a puzzled expression, “You mean a chocolate sundae?”

“No, I want a dish of chocolate ice cream with whipped cream,” was my response.

“Well, that’s a chocolate sundae without the syrup,” replied the waitress.

“Isn’t it just chocolate ice cream with whipped cream? What’s the difference?” I inquired.

“Well, a sundae is 35 cents and plain ice cream is 25 cents. What you want is a sundae without the syrup,” replied the waitress, with a rather smug expression on her face.

“OK, I want chocolate ice cream with whipped cream, so if you have to charge me 10 cents more, go ahead,” was my reply. (This took place in the ’50s when a dollar was worth a lot more than it is today.)
[...]
And for the next few weeks, each time I ordered my favorite dessert, regardless of the restaurant, I’d still go through the same hassle.One evening, after having worked really hard during the day, I was finishing my meal in a restaurant in mid-town Manhattan when the waitress looked at me and asked, “Would you
like dessert?”

I really wanted my favorite, but I just didn’t feel like going through the entire verbal routine that I had been experiencing for the last few weeks. “I’ll have a dish of chocolate ice cream,” was my response. I didn’t ask for the whipped cream. This was a simple request — one I didn’t expect a hassle over.

As the waitress was walking away, I thought to myself, in what must have been a fraction of a second, how much I really wanted chocolate ice cream with whipped cream and that I should not let myself be intimidated by a waitress. “Hey, miss,” I called, as the waitress was still walking away, “could you put whipped cream on that ice cream?”

“Sure,” was her response. “No problem.”

When the check came, I noticed that I had been charged just 25 cents for the ice cream and whipped cream — something that I had been charged 35 cents before.

How is this used in sales?

A good example of this can be seen at car dealerships. The salesperson tallies your entire order, gets approval from the general manager, and then has you sign the purchase contract. As she is walking away to get the car prepped and ready for you to drive it away, she turns to you and says, “And you do want that undercoating, don’t you?” You instinctively nod your head. The charge is added to your invoice. “And you’ll also want our floor mats to keep your car clean as well, won’t you?”

Once a commitment is made, the tendency is to act consistently with that commitment. The customer nods his head.
[...]
One of the important points to remember is to always make that first sale simple. Once the prospect makes the commitment to purchase from you, you can then easily offer more to increase your sales. This is very true for products sold from a mail order ad or from a TV infomercial. I have learned to keep the initial offer extremely simple. Then, once the prospect calls and orders the product I am offering, and while the prospect is on the phone, I offer other items and end up with a larger total sale. An additional sale occurs over 50% of the time, depending on my added offer.

Critical Chain 4

Thursday, September 20th, 2007

I’ve been discussing Eli Goldratt’s third business novel, Critical Chain, which explores project management.

Goldratt’s primary point is that padding individual task estimates with safety just means that a lot of time gets wasted. All that safety should get pooled into a few strategically placed buffers.

But Goldratt makes a secondary point about multi-tasking — namely that it does terrible things to lead times.

Imagine that you have three tasks to get done — X, Y, and Z — and each takes 10 days to finish. Your lead time should be 10 days for each task.



If, on the other hand, you start each task, get it half done, then flit to another of the tasks, get it half done, then work on the remaining untouched task, and get it half done, before returning to the first and finishing it, then your lead time will double to 20 days for each task.

Now, Goldratt only hints at this in Critical Chain, but how bad is extra lead time? Does it matter? Well, yes and no. For any task not on the critical path, no, it shouldn’t matter, not as long as there’s enough slack. For any task on the critical path, yes, of course, it matters a great deal.

To play devil’s advocate for a moment though, when would it make sense to switch away from Task X to Task Y? Goldratt asserts that workers multi-task simply to keep busy — and I’m sure that’s often the case — but what happens when you can work on Task X, but Task Y is critical? You work on Task X until Task Y is ready for you, then you switch to Task Y, leaving Task X half done. What happens when Task Z, which is even more critical, is ready for you? You switch to it.

The problem comes when you switch back to Task X without finishing Z, then Y, because those were the more critical tasks; otherwise you never would have — or never should have — switched to them in the first place.



In such a case, starting a low-priority task early, to keep busy, might inflate lead time numbers, but it doesn’t hurt the project’s progress at all.

The key is always knowing which tasks are critical or threatening to become critical — to have buffer-driven task priorities. By looking at each path’s relative buffer burn rate — the percentage of the buffer penetrated versus the percentage of work completed on that path — we can immediately see which paths, and thus which tasks, deserve priority.

Strategy Letter VI

Thursday, September 20th, 2007

I recommend Joel Spolsky’s Strategy Letter VI, which looks to explain the future by looking at the past:

In the late 80s, Lotus was trying very hard to figure out what to do next with their flagship spreadsheet and graphics product, Lotus 1-2-3. There two obvious ideas: first, they could add more features. Word processing, say. This product was called Symphony. Another idea which seemed obvious was to make a 3-D spreadsheet. That became 1-2-3 version 3.0.

Both ideas ran head-first into a serious problem: the old DOS 640K memory limitation. IBM was starting to ship a few computers with 80286 chips, which could address more memory, but Lotus didn’t think there was a big enough market for software that needed a $10,000 computer to run. So they squeezed and squeezed. They spent 18 months cramming 1-2-3 for DOS into 640K, and eventually, after a lot of wasted time, had to give up the 3D feature to get it to fit. In the case of Symphony, they just chopped features left and right.

Neither strategy was right. By the time 123 3.0 was shipping, everybody had 80386s with 2M or 4M of RAM. And Symphony had an inadequate spreadsheet, an inadequate word processor, and some other inadequate bits.

“That’s nice, old man,” you say. “Who gives a fart about some old character mode software?”

Humor me for a minute, because history is repeating itself, in three different ways, and the smart strategy is to bet on the same results.
