Moore’s Law Is Dead. Long Live Huang’s Law.

1 Share

In Part 2 of my great robot trilogy,¹ I talked a bit about the steady demise of Moore’s Law, which ever since 1965 has predicted that computing power doubles every 18 months or so. Obviously Moore’s Law was good for artificial intelligence, which requires vast computing power, and its death is just as obviously bad news. However, there are many ways to skin a cat, and raw, general computing power is only one of them. In the Wall Street Journal this weekend, Christopher Mims introduces us to a replacement for Moore’s Law:

I call it Huang’s Law, after Nvidia Corp. chief executive and co-founder Jensen Huang….Between November 2012 and this May, performance of Nvidia’s chips increased 317 times for an important class of AI calculations, says Bill Dally, chief scientist and senior vice president of research at Nvidia. On average, in other words, the performance of these chips more than doubled every year, a rate of progress that makes Moore’s Law pale in comparison.

Nvidia’s specialty has long been graphics processing units, or GPUs, which operate efficiently when there are many independent tasks to be done simultaneously. Central processing units, or CPUs, like the kind that Intel specializes in, are on the other hand much less efficient but better at executing a single, serial task very quickly. You can’t chop up every computing process so that it can be efficiently handled by a GPU, but for the ones you can—including many AI applications—you can perform it many times as fast while expending the same power.

Experts agree that the phenomenon I’ve labeled Huang’s Law is advancing at a blistering pace. However, its exact cadence can be difficult to nail down. The nonprofit Open AI says that, based on a classic AI image-recognition test, performance doubles roughly every year and a half. But it’s been a challenge even agreeing on the definition of “performance.” A consortium of researchers from Google, Baidu, Harvard, Stanford and practically every other major tech company are collaborating on an effort to better and more objectively measure it.

Another caveat for Huang’s Law is that it describes processing power that can’t be thrown at every application. Even in a stereotypically AI-centric task like autonomous driving, most of the code the system is running requires the CPU, says TuSimple’s Mr. Hou. Dr. Dally of Nvidia acknowledges this problem, and says that when engineers radically speed up one part of a calculation, whatever remains that can’t be sped up naturally becomes the bottleneck.

This is how we’re going to get the processing power needed to develop true AI. General purpose CPUs may be close to their ultimate limits, but AI is so important that it’s worth investing lots of money in specialized hardware (and software) for highly specific neural tasks. At the moment, we’re repurposing graphics chips, which turn out to be (a) well suited for many AI applications, and (b) still have a lot of headroom to deliver better and better performance. In time, we’ll develop chips that are even more specialized, something that Google is already working on.

So don’t cry for the death of Moore’s Law. It was great while it lasted, but its end is far from the end of high-power computing. AI is coming, and when it does its hardware foundations will most likely look nothing like today’s generic computers. Huang’s Law now rules our world.

¹Part 1 is here. Part 3 is still a couple of years away.

Chronicle Sees Promise, But Imperfections, in Eldorado Cafe

1 Share

Austin Monthly has quibbles with Bao’d Up

In her first review for the Chronicle, Jessi Cape visited Eldorado Cafe and declared it a new neighborhood favorite. The is Tex-Mex restaurant helmed by Joel Fried, formerly of Tacodeli, is located in a fairly nondescript strip mall, but Cape found the place full of bustle and color inside.

Of the interior, Cape praised, “This looks, and feels, like the home of a cool friend.” Though met with a 35-minute wait for Tuesday dinner, Cape found the service calm and attentive.

When it came to the cuisine, Cape found it overall satisfying, with some stumbles. On the chicken suizas, she lamented “while flavorful, the creamy verde sauce was a tad thick, and the chicken was dry.” For a side dish of Calabasas hash (butternut squash, zucchini, roasted garlic, with toasted pepitas and basil), she noted “had it been served piping hot, the flavors would have bloomed more” However, the papas rellenas, queso, and breakfast tacos all got high marks.

However, Cape’s favorite bite came with the short rib salpicon:

Hailing from many global cuisines, the dish entails adobo-braised short ribs shredded with roasted chiles, tomato, and sherry. Served with pickled red onions, guacamole, and fresh tortillas, it was delicious. Juicy, with the individual spice notes of paprika and garlic coming through well-balanced, it's also delicious scrambled with fluffy eggs as it's served on the breakfast menu.

Austin Monthly’s Kimya Kavehkar stopped by Bao’d Up in the Mueller area, to similarly mixed results. While she clearly delighted in the bao itself (“Biting into a soft and sweet bao is like opening a present”), she mentioned issues with the service and boba.

Of the different bao, Kavekhar reported she “enjoyed the crunch of the fried chicken GuaBao and the BBQ pork Baozi, which is tangy and a little sweet.” While the flavor of the tea fell short (“[t]he boba isn’t the best in town”), she did appreciate the many customization options.

Overall, Kavehkar thought the restaurant is a great addition:

The service is a bit slower at lunch (our boba didn’t hit the table until we’d finished eating our bao) and can feel harried and chaotic during busier times. But the product is pretty darn delicious, and having more access to international street foods only ups the cool, cosmopolitan factor for our city.

Atlantic Tele-Network’s Valuation Ignores Profitable and Growing Segments – ATNI

1 Share

218789

Atlantic Tele-Network owns a diverse collection of wireless and wireline telecom assets in the rural US and the Caribbean. The company’s insiders are large shareholders and have an excellent track record of growing book value and dividends. ATN recently closed on the sale of a major segment to AT&T, receiving nearly triple what ATN paid for the business only three years ago. Post the transaction, Atlantic Tele-Network is debt-free with a large cash hoard and profitable remaining operations, the values of which exceed the company’s enterprise value.

Founded in 1987, ATN got its start providing telecom services in the South American nation of Guyana and the US Virgin Islands. From there, the company expanded to Bermuda and other Caribbean Islands, and into the US, focusing on rural markets with little competition from large telecom providers. Along the way, ATN grew its revenues and operating income from $117.6 million and $18.1 million in 1997 to $741.4 million and $99.5 million in 2012. Shareholders were richly rewarded from this growth. From the end of 1997 to the end of 2013, Atlantic Tele-Network stock returned an astounding 23.8% annually. The largest beneficiaries of this value creation were the father and son team that runs ATN, Cornelius B. Prior and Michael T. Prior. Together, and including trusts for their benefit, these men own 36.88% of ATN’s stock, worth some $359 million. Michael T. Prior has taken over the leadership role from his elderly father, and his large ownership stake aligns his interests with those of shareholders.

Atlantic Tele-Network holds itself out as a nimble investor, willing to sell a division when the time is right and to go all in on the right opportunity. A shining example of that is the company’s recent Alltel transaction. As part of Verizon Wireless’s acquisition of Alltel in 2008, Verizon was required to divest certain parts of Alltel’s network. In 2010, ATN snapped up Alltel’s operations in Idaho, Ohio, Georgia, Illinois and the Carolinas. ATN paid $200 million for Alltel, funding the purchase entirely with debt. Only three years later, ATN announced the sale of Alltel to AT&T for $780 million, plus a small working capital adjustment. For the price of a few years’ interest payments, ATN created $580 million in value for its shareholders, pre-tax. The sale of Alltel closed in September 2013.

Atlantic Tele-Network used the proceeds of the Alltel transaction to eliminate all its debt. After paying taxes on the transaction and making a distribution to minority shareholders in Alltel, the company has net cash of $389 million, of which $79 million is escrowed for up to 18 months. ATN’s market capitalization is $973.6 million, yielding an enterprise value of $584.2 million.

Capture

 

 

Atlantic Tele-Network’s enterprise value is far below the fair value of its remaining subsidiary businesses. While a full survey of each of these would run thousands of words, I’ll do my best to summarize them for this blog post. There are four major segments, which I’ll tackle in order of descending revenues.

US Wireless Operations

ATN’s subsidiary, Commnet, provides cellular services to remote areas across the West, from the plains to the Rockies. Commnet’s assets include 579 cellular base stations across the region. Though Commnet brings in much less revenue than the divested Alltel, Commnet enjoys much higher profitability. For the first nine months of 2013, Commnet’s EBITDA margin was 65.3%, practically unheard of for a cellular operator. This EBITDA margin speaks to how little competition Commnet faces in its remote markets. Commnet is also experiencing good growth, with revenues for the third quarter of 2013 up 12.9% over the previous year. Much of the rise is due to increasing data traffic on the network. ATN is in the process of upgrading much of Commnet’s network from 2G to 3G standards, which will increase data throughput. (However, the company warns that some of the increased data revenues will be offset by planned reductions in data transfer prices.)

For the first nine months of 2013, Commnet earned $52.59 million in EBITDA, putting the segment on pace to hit $70.12 million for 2013. The simplest means of valuing the segment is to apply the same multiple of EBITDA as ATN received for its sale of Alltel, also a rural wireless provider. (With its soaring data throughput and extraordinary margins, Commnet may be worth quite a bit more, but it always pays to err toward the conservative side.) AT&T’s purchase of Alltel was done at 7.70x annualized trailing EBITDA, which implies a valuation of $539.93 million for Commnet. Increasing or decreasing the valuation by one turn of EBITDA expands that range to $469.81 million to $610.05 million.

International Integrated Telephony

ATN’s second largest segment is its Guyana telecom provider, GT&T, which enjoys exclusivity on long-distance calling in Guyana. GT&T also offers wireless and internet services. Atlantic Tele-Network owns 80% of GT&T, with the rest formerly owned by the government of Guyana and now by a third party. GT&T’s revenues and earnings have generally experienced modest declines in recent years, with trailing twelve months revenues down 7.9% since 2008 and EBIT down 17.4%. GT&T’s results are also threatened by new legislation in Guyana’s parliament, which may strip GT&T of its monopoly on long-distance telephone service in Guyana. Atlantic Tele-Network states that it hopes some of the lost business due to regulatory changes would be made up in increased local calling activity.

GT&T produced $43.84 million in EBITDA for the trailing twelve months, of which $35.07 million is attributable to ATN. Given the long-term decline in revenue and earnings and the regulatory uncertainty, GT&T warrants a low valuation. Assigning an EBITDA multiple of 4.0x trailing results implies a value of $140.29 million. Expanding that range to 3.0x-5.0x EBITDA gives a range of $105.22 million to $175.36 million.

Island Wireless

ATN’s third largest segment is Island Wireless. Through various subsidiaries, Atlantic Tele-Network provides cellular service to several Caribbean islands, including Bermuda, Turks & Caicos, the US Virgin Islands and others. The Island Wireless segment has shown strong revenue growth, expanding 188% from 2008 to the twelve months ended September 30, 2013. The most recent quarter’s revenues were up 11.6% over the previous year. As it has grown, Island Wireless has reached the point where additional revenues drop nearly unimpeded to EBIT. As revenues increased by $15.05 million from 2011 to the trailing twelve months, EBIT increased by $14.44 million. The segment’s EBITDA and EBIT margins continue to expand, reaching 22.1% and 6.5% on a trailing basis. For the most recently reported quarter, the segment’s EBITDA margin reached 33.5%. In the last quarter’s earnings call, management indicated this level of profitability is “somewhat sustainable.” Assuming a sustainable EBITDA margin midway between the most recent quarter and the twelve trailing months, or 27.8%, Island Wireless can produce annual EBITDA of  $18.40 million, based on the twelve trailing months’ revenues. Given that Island Wireless is still growing at a healthy pace and enjoying positive operating leverage as it does so, the segment warrants a valuation above those of the company’s other businesses. Valuing Island Wireless at 9.0x trailing normalized EBITDA yields a valuation of $165.58 million. Expanding that range to 8.0x-10.0x trailing EBITDA widens the valuation band to $147.18 million to $183.97 million.

US Wireline

Finally, ATN owns wireline assets in the US Northeast, operating as Sovernet Communications. These operations are currently only minimally profitable, producing trailing EBITDA of $2.98 million and trailing EBIT of negative $1.61 million. However, ATN is close to completing a fiber optic network in Sovernet’s service area, which will increase the segment’s capabilities and revenues. It is difficult to assess the impact of the expansion on revenues and earning, so I choose to estimate the US Wireline segment’s value as the book value of its assets instead. As of September 30, 2013, the segment had assets with a book value of $43.86 million, up $12.97 million from the previous year-end on strong capital investment.

Aggregate Valuation

The combined value of Atlantic Tele-Networks’ various operating subsidiaries and excess cash is substantially higher than its current trading price, even using the conservative end of already conservative projections. The EBITDA multiple ranges I used to value the various segments are typical of low or no-growth companies, when the company’s large US wireless and Island Wireless segments are still experiencing strong revenue increases.

Capture2

 

Using even the most conservative valuation multiples, Atlantic Tele-Network stock is worth nearly 20% more than its current trading prices. Extra value could be created if management finds another bargain like Alltel, or can successfully introduce high-margin products into its existing markets. Atlantic Tele-Network’s downside is limited by its strong cash position and the defensive nature of the telecom industry.

Facebook's 'Paper' App Is Basically A Massive Redesign Of Facebook — And It's Excellent (FB)

1 Share

facebook Paper

Facebook launched its "news" app, Paper, today but the first thing you'll notice when you use it is how much more awesome Facebook would be if it was like Paper.

The app lets you read news and see headlines in a highly visual format, with lots of nice photos. It's a bit like Flipboard, the acclaimed "magazine" app with flipping pages. But that does an injustice to Facebook — Paper is much more cleverly designed than Flipboard.

It's more versatile, there's a lot more to do, and it's more personalized.

And that's because Paper basically is a redesigned Facebook. Paper is Facebook as if it were a brand new app, designed from scratch by a new tech startup specifically for mobile phones.

This is significant because Facebook, notoriously, is a product of the desktop age. It was designed by Mark Zuckerberg on his desktop/laptop computer at Harvard, three years before smartphones were invented. Facebook was only fully reverse-engineered for mobile in late 2013/early 2013.

And, it kinda shows. The Facebook app is good, but not great. Facebook's Messenger app (basically it's just the messages function of Facebook in a standalone app) is miles better. Instagram (another standalone Facebook app for photos) is miles better. They are better because they focus on one thing, and do it simply.

Paper appears to be Facebook's answer to the question, "If we were to re-create Facebook as a standalone app that delivered a beautiful, simple, highly focused experience, what would it look like?"

Well, it looks like Paper.

Paper combines everything — news headlines, your personal Facebook news feed, messages and status updates — into a single format. The swiping actions you need to learn are initially somewhat confusing. But the way photos are displayed, so that they pan from side to side as you tilt the phone, make them appear much bigger than they are.

It's a startlingly efficient and elegant use of the medium.

Sure, you can go on assuming that Paper is Facebook's "news" app. I think it's a Facebook redesign by the backdoor.

T-rex Calories

4 Comments and 14 Shares

T-rex Calories

If a T-rex were released in New York City, how many humans/day would it need to consume to get its needed calorie intake?

Tony Schmitz

About half of an adult, or one ten-year old child:

Tyrannosaurus rex weighed about as much as an elephant.[1]This always seemed a little off to me; my mental image of elephants is that they're in the same size range as cars or trucks, whereas T-rex, as Jurassic Park showed, is big enough to stomp on cars. But a Google image search for car+elephant shows elephants looming over cars just like the T-rex in Jurassic Park. So, great, now I'm also afraid of elephants.

No one is totally sure what dinosaur metabolism looked like, but the best guesses for how much food T-rex ate seem to cluster around 40,000 calories per day.[2] Food calories (kcal). Sources: This and this, and this with some notes from this and distraction from this.

If we assume dinosaurs had metabolisms similar to today's mammals, they'd eat a lot more than 40,000 calories each day. But the current thinking is that while dinosaurs were more active (loosely speaking, "warm-blooded") than modern snakes and lizards, very large dinosaurs probably had metabolisms that more closely resembled komodo dragons than elephants and tigers.[3]For big sauropods, we know this must be the case, because otherwise they would overheat. However, there's a lot of uncertainty surrounding T-rex-sized dinosaurs.

Next, we need to know how many calories are in a human. This number is helpfully provided, by Dinosaur Comics author Ryan North, on this wonderful t-shirt. Ryan's shirt tells us that an 80-kg human contains about 110,000 food calories of energy.

Therefore, a T-rex would need to consume a human every two days or so.[4]Although a T-rex would likely be willing to eat several days to weeks worth of food in one meal, so if it has the option, it might eat a bunch of people at a time, then go for a while without eating. The city of New York had 239,736 births in 2011, which could support a population of about 1,000 tyrannosaurs. However, this ignores immigration—and, more importantly, emigration, which would probably increase substantially in this scenario.

The 33,000 McDonald's restaurants worldwide sell something like 15 billion hamburger patties per year,[5]They stopped reporting the "x billions served" number on their signs, but this website has some extrapolations. for an average of 1,245 burgers per restaurant per day. 1,245 burgers is about 600,000 calories, which means that each T-rex only needs about 80 hamburgers per day to survive, and one McDonald's could support over a dozen tyrannosaurs on hamburgers alone.

Ands if you live in New York, and you see a T-rex, don't worry. You don't have to choose a friend to sacrifice; just order 80 burgers instead.

And then if the T-rex goes for your friend anyway, hey, you have 80 burgers.

1245 burgers per day per McDonalds. That's a lot of burgers! Wonder what the median is?

Assuming a 14 hour lunch/dinner menu, thats a burger about every 40 seconds. Figure not everyone gets a burger, but some people order more than one, so lets call it an order per minute. Between the drive in and the counter, I'd say it seems about right.
