Nothing says "edgy recruiting" like a child soldier. Very classy, @vonchurch

No big deal.

We present Masstree, a fast key-value database designed for SMP machines. Masstree keeps all data in memory. Its main data structure is a trie-like concatenation of B+-trees, each of which handles a fixed-length slice of a variable-length key. This structure effectively handles arbitrary-length possibly binary keys, including keys with long shared prefixes. B+-tree fanout was chosen to minimize total DRAM delay when descending the tree and prefetching each tree node. Lookups use optimistic concurrency control, a read-copy-update-like technique, and do not write shared data structures; updates lock only affected nodes. Logging and checkpointing provide consistency and durability. Though some of these ideas appear elsewhere, Masstree is the first to combine them. We discuss design variants and their consequences.

“Tech company” and “tech startup” are over-applied labels that have outlived their usefulness. Calling practically all growing contemporary businesses “technology companies” is about as useful as calling the enterprises of the industrial era “factory companies”; it accurately describes an aspect of what they are (or were), but it doesn’t really capture the totality of their operation. It certainly doesn’t tell you anything substantive about how they’ll behave in the market over the long term, which is probably the most useful reason to label a business at all.

What eventually became Pyramid Mountain in the Verhoeven version was originally a prehistoric Martian sphinx excavated from the Martian desert, and a good deal more screen time was have been allotted to Kuato, including an elaborate dream sequence where he morphed first into the sphinx and then into a kind of phosphorescent vagina. Cronenberg had some very Cronenberg touches, such as agents with guns hidden within their bodies, but absolutely my favorite idea of all those we came up with was to have camels imported from earth to haul freight across the Martian deserts. This would, of course, have been after significant terraforming had already been done...but not so much that the camels didn't have to wear respirators!

Atlassian's new office. Wow.

Kimo's high expectations set a new pace for me. He taught me “the standard pace is for chumps” - that the system is designed so anyone can keep up. If you're more driven than “just anyone” - you can do so much more than anyone expects. And this applies to ALL of life - not just school.

In order to understand what a fallacy is, one must understand what an argument is. Very briefly, an argument consists of one or more premises and one conclusion. A premise is a statement (a sentence that is either true or false) that is offered in support of the claim being made, which is the conclusion (which is also a sentence that is either true or false).

There are two main types of arguments: deductive and inductive. A deductive argument is an argument such that the premises provide (or appear to provide) complete support for the conclusion. An inductive argument is an argument such that the premises provide (or appear to provide) some degree of support (but less than complete support) for the conclusion. If the premises actually provide the required degree of support for the conclusion, then the argument is a good one. A good deductive argument is known as a valid argument and is such that if all its premises are true, then its conclusion must be true. If all the argument is valid and actually has all true premises, then it is known as a sound argument. If it is invalid or has one or more false premises, it will be unsound. A good inductive argument is known as a strong (or "cogent") inductive argument. It is such that if the premises are true, the conclusion is likely to be true.

A fallacy is, very generally, an error in reasoning. This differs from a factual error, which is simply being wrong about the facts. To be more specific, a fallacy is an "argument" in which the premises given for the conclusion do not provide the needed degree of support. A deductive fallacy is a deductive argument that is invalid (it is such that it could have all true premises and still have a false conclusion). An inductive fallacy is less formal than a deductive fallacy. They are simply "arguments" which appear to be inductive arguments, but the premises do not provided enough support for the conclusion. In such cases, even if the premises were true, the conclusion would not be more likely to be true.

MIT's Technology Review has just gotten news of a mysterious new project that claims it will "create a new industry and a new definition of 'natural resources.'" Space exploration company Planetary Resources will be unveiled in a conference call on Tuesday, April 24th. Besides the audacious announcement, which promises to "overlay two critical sectors — space exploration and natural resources — to add trillions of dollars to the global GDP," what makes this unique is its high-profile support group. The venture is backed by Google executives Larry Page and Eric Schmidt, director James Cameron, and politician Ross Perot's son, among others.

Whenever someone proposes to do something that has never been done before, there will always be skeptics.

So when I started SpaceX, it was not surprising when people said we wouldn’t succeed. But now that we’ve successfully proven Falcon 1, Falcon 9 and Dragon, there’s been a steady stream of misinformation and doubt expressed about SpaceX’s actual launch costs and prices.

As noted last month by a Chinese government official, SpaceX currently has the best launch prices in the world and they don’t believe they can beat them. This is a clear case of American innovation trumping lower overseas labor rates.

I recognize that our prices shatter the historical cost models of government-led developments, but these prices are not arbitrary, premised on capturing a dominant share of the market, or “teaser” rates meant to lure in an eager market only to be increased later. These prices are based on known costs and a demonstrated track record, and they exemplify the potential of America's commercial space industry.

Here are the facts:

The price of a standard flight on a Falcon 9 rocket is $54 million. We are the only launch company that publicly posts this information on our website (www.spacex.com). We have signed many legally binding contracts with both government and commercial customers for this price (or less). Because SpaceX is so vertically integrated, we know and can control the overwhelming majority of our costs. This is why I am so confident that our performance will increase and our prices will decline over time, as is the case with every other technology.

The average price of a full-up NASA Dragon cargo mission to the International Space Station is $133 million including inflation, or roughly $115m in today’s dollars, and we have a firm, fixed price contract with NASA for 12 missions. This price includes the costs of the Falcon 9 launch, the Dragon spacecraft, all operations, maintenance and overhead, and all of the work required to integrate with the Space Station. If there are cost overruns, SpaceX will cover the difference. (This concept may be foreign to some traditional government space contractors that seem to believe that cost overruns should be the responsibility of the taxpayer.)

The total company expenditures since being founded in 2002 through the 2010 fiscal year were less than $800 million, which includes all the development costs for the Falcon 1, Falcon 9 and Dragon. Included in this $800 million are the costs of building launch sites at Vandenberg, Cape Canaveral and Kwajalein, as well as the corporate manufacturing facility that can support up to 12 Falcon 9 and Dragon missions per year. This total also includes the cost of five flights of Falcon 1, two flights of Falcon 9, and one up and back flight of Dragon.

The Falcon 9 launch vehicle was developed from a blank sheet to first launch in four and half years for just over $300 million. The Falcon 9 is an EELV class vehicle that generates roughly one million pounds of thrust (four times the maximum thrust of a Boeing 747) and carries more payload to orbit than a Delta IV Medium.

The Dragon spacecraft was developed from a blank sheet to the first demonstration flight in just over four years for about $300 million. Last year, SpaceX became the first private company, in partnership with NASA, to successfully orbit and recover a spacecraft. The spacecraft and the Falcon 9 rocket that carried it were designed, manufactured and launched by American workers for an American company. The Falcon 9/Dragon system, with the addition of a launch escape system, seats and upgraded life support, can carry seven astronauts to orbit, more than double the capacity of the Russian Soyuz, but at less than a third of the price per seat.

SpaceX has been profitable every year since 2007, despite dramatic employee growth and major infrastructure and operations investments. We have over 40 flights on manifest representing over $3 billion in revenues.

These are the objective facts, confirmed by external auditors. Moreover, SpaceX intends to make far more dramatic reductions in price in the long term when full launch vehicle reusability is achieved. We will not be satisfied with our progress until we have achieved this long sought goal of the space industry.

For the first time in more than three decades, America last year began taking back international market-share in commercial satellite launch. This remarkable turn-around was sparked by a small investment NASA made in SpaceX in 2006 as part of the Commercial Orbital Transportation Services (COTS) program. A unique public-private partnership, COTS has proven that under the right conditions, a properly incentivized contractor — even an all-American one — can develop extremely complex systems on rapid timelines and a fixed-price basis, significantly beating historical industry-standard costs.

China has the fastest growing economy in the world. But the American free enterprise system, which allows anyone with a better mouse-trap to compete, is what will ensure that the United States remains the world’s greatest superpower of innovation.

When a swarm of crabs is placed into a corridor with walls on each side, the crabs will closely follow the wall like a rolling billiard ball. This sort of behavior can be easily controlled, for example, by casting a shadow from above on the swarm to mimic the presence of crab-eating birds. The soldier crabs will move away from any shadowed areas for fear of being munched on. When two swarms of crabs — or “crab balls” — collide, they appear to merge and continue in a direction that is the sum of their respective velocities.

Based on these observations of crab behavior, the team built a pattern of channels that act like logic gates. They first simulated the soldier crab swarming behavior in special patterns of channels. They then created a real system of channels in their lab and unleashed groups of 40 real crabs, which were guided using the fake bird shadow.

They found that they could build a decent OR gate using the crabs — this was the place where one or two crab swarms are merged into a single one. However, the more complicated AND-gate required the combined swarm heading down one of three paths. This was found to be less reliable. However, the team believe that they could improve the results by creating a more crab-friendly environment.

OpenFlow enables networks to evolve, by giving a remote controller the power to modify the behavior of network devices, through a well-defined "forwarding instruction set". The growing OpenFlow ecosystem now includes routers, switches, virtual switches, and access points from a range of vendors.

Delay-tolerant networking (DTN) is a term invented to describe and encompass all types of long-delay, disconnected, disrupted or intermittently-connected networks, where mobility and outages or scheduled contacts may be experienced. 'DTN' is also used to refer to the Bundle Protocol, which has been proposed as the one unifying solution for disparate DTN networking scenarios, after originally being designed solely for use in deep space for the 'Interplanetary Internet.' We evaluated the Bundle Protocol by testing it in space and on the ground. We have found architectural weaknesses in the Bundle Protocol that may prevent engineering deployment of this protocol in realistic delay-tolerant networking scenarios, and have proposed approaches to address theses weaknesses.

to you, you are just f*cking stupid.

Carmack on demoscenes and programming for old platforms

Gabe tells it this way. When he was at Microsoft in the early 90’s, he commissioned a survey of what was actually installed on users’ PCs. The second most widely installed software was Windows.

Number one was Id’s Doom.

The idea that a 10-person company of 20-somethings in Mesquite, Texas, could get its software on more computers than the largest software company in the world told him that something fundamental had changed about the nature of productivity. When he looked into the history of the organization, he found that hierarchical management had been invented for military purposes, where it was perfectly suited to getting 1,000 men to march over a hill to get shot at. When the Industrial Revolution came along, hierarchical management was again a good fit, since the objective was to treat each person as a component, doing exactly the same thing over and over.

The success of Doom made it obvious that this was no longer the case. There was now little value in doing the same thing even twice; almost all the value was in performing a valuable creative act for the first time. Once Doom had been released, any of thousands of programmers and artists could create something similar (and many did), but none of those had anywhere near the same impact. Similarly, if you’re a programmer, you’re probably perfectly capable of writing Facebook or the Google search engine or Twitter or a browser, and you certainly could churn out Tetris or Angry Birds or Words with Friends or Farmville or any of hundreds of enormously successful programs. There’s little value in doing so, though, and that’s the point – in the Internet age, software has close to zero cost of replication and massive network effects, so there’s a positive feedback spiral that means that the first mover dominates.

If most of the value is now in the initial creative act, there’s little benefit to traditional hierarchical organization that’s designed to deliver the same thing over and over, making only incremental changes over time. What matters is being first and bootstrapping your product into a positive feedback spiral with a constant stream of creative innovation. Hierarchical management doesn’t help with that, because it bottlenecks innovation through the people at the top of the hierarchy, and there’s no reason to expect that those people would be particularly creative about coming up with new products that are dramatically different from existing ones – quite the opposite, in fact. So Valve was designed as a company that would attract the sort of people capable of taking the initial creative step, leave them free to do creative work, and make them want to stay. Consequently, Valve has no formal management or hierarchy at all.

To be effective, airport security needs to embrace flexibility and risk management—principles that it is difficult for both the bureaucracy and the public to accept. The public wants the airport experience to be predictable, hassle-free and airtight and for it to keep us 100% safe. But 100% safety is unattainable. Embracing a bit of risk could reduce the hassle of today's airport experience while making us safer at the same time.

Over the past 10 years, most Americans have had extensive personal experience with the TSA, and this familiarity has bred contempt. People often suggest that the U.S. should adopt the "Israeli method" of airport security—which relies on less screening of banned items and more interviewing of passengers. But Israeli citizens accept the continued existence of a common enemy that requires them to tolerate necessary inconveniences, and they know that terror plots are ongoing.

In America, any successful attack—no matter how small—is likely to lead to a series of public recriminations and witch hunts. But security is a series of trade-offs. We've made it through the 10 years after 9/11 without another attack, something that was not a given. But no security system can be maintained over the long term without public support and cooperation. If Americans are ready to embrace risk, it is time to strike a new balance.

A speculative hypothesis is presented according to which the ancient Israelite religion was associated with the use of entheogens (mind-altering plants used in sacramental contexts). The hypothesis is based on a new look at the texts of the Old Testament pertaining to the life of Moses. The ideas entertained here were primarily based on the fact that in the arid areas of the Sinai peninsula and Southern Israel there grow two plants containing the same psychoactive molecules found in the plants from which the powerful Amazonian hallucinogenic brew Ayahuasca is prepared. The two plants are species of Acacia tree and the bush Peganum harmala. The hypothesis is corroborated by comparative experiential-phenomenological observations, linguistic considerations, exegesis of old Jewish texts and other ancient Mideastern traditions, anthropological lore, and ethnobotanical data.

Initially, we felt MongoDB gave us the flexibility and power we needed in a database. Unfortunately, underlying architectural issues forced us to investigate other solutions rather quickly. We never attempted to horizontally scale MongoDB since our confidence in the product was hurt by the time that was offered as a solution, and because we believe horizontally scaling shouldn’t be necessary for the relatively small amount of ops per second we were sending to MongoDB.

Over the past 6 months, we’ve “scaled” MongoDB by moving data off of it. This process is an entire blog post itself, but the gist of the matter is that we looked at our data access patterns and chose the right tool for the job. For key-value data, we switched to Riak, which provides predictable read/write latencies and is completely horizontally scalable. For smaller sets of relational data where we wanted a rich query layer, we moved to PostgreSQL. A small fraction of our data has been moved to non-durable purely in-memory solutions if it wasn’t important for us to persist or be able to query later.

In retrospect, MongoDB was not the right solution for Kiip. Although it may be a bit more upfront effort, we recommend using PostgreSQL (or some traditional RDBMS) first, then investigating other solutions if and when you find them necessary. In future blog posts, we’ll talk about how we chose our data stores and the steps we took to migrate data while minimizing downtime.

Called the Hutchinson Letters Affair, it began in December, 1772 when Benjamin Franklin, who was in England at the time, anonymously received a packet of thirteen letters. They were reports by Thomas Hutchinson, the lieutenant governor of the Province of Massachusetts Bay, to Thomas Whately, a leading member of the British government. In the letters, Hutchinson made some damning comments about colonial rights. Even more provocative, Hutchinson recommended that popular government be taken away from the colonists “by degrees”, and that there should be “abridgement of what are called English liberties”. Specifically, he argued that all colonial government posts should be made independent of the provincial assemblies. Finally, he urged his superiors to send more troops to Boston to keep American rebels under control.

Understanding the inflammatory nature of these letters, Franklin circulated the letters to his American friends and colleagues but on the condition that they not be published. Clearly in the public interest, at least from the point-of-view of American revolutionaries, the letters were published, in defiance of Franklin’s request,  in the Boston Gazette in June of 1773.

As you can imagine, the patriotic citizens of Boston were furious, and in May 1774 Hutchinson fled the colony back to England before he could be tarred and feathered. As the American colonies were on the edge of rebelling against the authority of the Crown, this could easily have triggered a revolution, and while it didn’t, it certainly provided the insurgents with ammunition in their fight against England.

Having been severely embarrassed and having had its interests in the American colonies compromised, the British government set out to discover who leaked the letters. In December of 1773, three men were charged, two of whom fought a duel over the matter and were preparing to do so again. As it turned out, they had nothing to do with the Hutchinson letters, and in a letter to the London Chronicle, Franklin confessed: “Finding that two gentlemen have been unfortunately engaged in a duel, about a transaction and its circumstance of which both are totally ignorant and innocent, I think it incumbent on me to declare (for the prevention of farther mischief, as far as such a declaration may contribute to prevent it) that I alone am the person who obtained and transmitted to Boston the letters in question.”  However, he refused to say who gave him the letters

I did have a legal point: Justice Kennedy's majority opinion in Lawrence asked whether criminalizing homosexual conduct advanced a state interest "which could justify the intrusion into the personal and private life of the individual." Scalia did not answer this question in his dissent because he believed the state need only assert a legitimate interest to defeat non-fundamental liberties. I basically asked him this question again--it is now the law of the land. He said he did not know whether the interest was significant enough. I then asked him if he sodomizes his wife to subject his intimate relations to the scrutiny he cavalierly would allow others--by force, if necessary. Everyone knew at that moment how significant the interest is. Beyond exerting official power against homosexuals, Scalia is an outspoken and high-profile homophobe. After the aforementioned sarcastic remarks about gay people's relationships, can anyone doubt how little respect he has for LGBT Americans? Even if no case touching gay rights ever came before him, his comments from the bench (that employment non-discrimination is some kind of "homosexual agenda," etc.) and within our very walls are unacceptable to any self-respecting gay person or principled opponent of discrimination. The idea that I should have treated a man with such repugnant views with deference because he is a high government official evinces either a dangerously un-American acceptance of authority or insensitivity to the gay community's grievances. Friends have forwarded me emails complaining of the "liberal" student who asked "the question." That some of my classmates are shallow and insensitive enough to conceptualize my complaint as mere partisan politics is disheartening. Though I should not have to, I will share with everyone that I am neither a Democrat nor Republican and do not consider myself a "liberal" except in the classical sense. I hope that we can separate a simple demand for equality under the law and outrage over being denied it from so much dogmatic ideological baggage. LGBT Americans are still a persecuted minority and our struggle for equal rights is still vital. Four out of five LGBT kids are harassed in school--tell them to debate their harassers. Suicide rates for them are much higher than for others. We still cannot serve in the military, have little protection from employment and other forms of discrimination, and are denied the 1,000+ benefits that accrue from official recognition of marriage. I know some who support gay rights oppose my question and our protest. Do not presume to tell me when and with how much urgency to stand up for our rights.

Moviemaker James Cameron has re-edited a scene in Titanic showing stars sparkling in the night sky - after a leading astronomer told him the astral alignment was incorrect.

The director unveiled a 3D version of his multi-Oscar winning classic last month (Mar12) and he resisted the temptation to use its reworking as an excuse to cut scenes he's no longer happy with.

But there was one shot Cameron felt obliged to alter, because a top stargazer informed him the astral pattern onscreen was incorrect for the night the liner sank in 1912.

The scene involves Kate Winslet's character, Rose DeWitt Bukater, drifting on a piece of wood and gazing at the night sky as the disaster unfolds.

Cameron tells British magazine Culture, "Oh, there is one shot that I fixed. It's because Neil deGrasse Tyson, who is one of the U.S.' leading astronomers, sent me quite a snarky email saying that, at that time of year, in that position in the Atlantic in 1912, when Rose is lying on the piece of driftwood and staring up at the stars, that is not the star field she would have seen, and with my reputation as a perfectionist, I should have known that and I should have put the right star field in.

"So I said, 'All right, you son of a b**ch, send me the right stars for the exact time, 4.20am on April 15, 1912, and I'll put it in the movie.' So that's the one shot that has been changed."

Following an orthopedic procedure, surgeons usually rely on X-rays or MRIs to monitor the progress of their patient's recovery. The new sensors, created by Rensselaer faculty researcher Eric Ledet, would instead give surgeons detailed, real-time information from the actual surgery site. This in vivo data could lead to more accurate assessments of a patient's recovery, or provide better insight into potential complications.

Alex Grey is developing a better kind of muscle sensor, to help people see their muscle activity patterns and change behaviors like typing or running to be more effective and less painful. The sensors are wireless, stick to your skin, and can measure different kinds of muscle activity including arm/leg (EMG) and heart muscles (ECG). In the video below, Alex describes how he used these sensors to find his optimal stride rate as a runner, as well as to detect when he was starting to fatigue or compensate on one side for an old injury.

November 16, 1973

Dear Mr. McCarthy:

I am writing to you in your capacity as chairman of the Drake School Board. I am among those American writers whose books have been destroyed in the now famous furnace of your school.

Certain members of your community have suggested that my work is evil. This is extraordinarily insulting to me. The news from Drake indicates to me that books and writers are very unreal to you people. I am writing this letter to let you know how real I am.

I want you to know, too, that my publisher and I have done absolutely nothing to exploit the disgusting news from Drake. We are not clapping each other on the back, crowing about all the books we will sell because of the news. We have declined to go on television, have written no fiery letters to editorial pages, have granted no lengthy interviews. We are angered and sickened and saddened. And no copies of this letter have been sent to anybody else. You now hold the only copy in your hands. It is a strictly private letter from me to the people of Drake, who have done so much to damage my reputation in the eyes of their children and then in the eyes of the world. Do you have the courage and ordinary decency to show this letter to the people, or will it, too, be consigned to the fires of your furnace?

I gather from what I read in the papers and hear on television that you imagine me, and some other writers, too, as being sort of ratlike people who enjoy making money from poisoning the minds of young people. I am in fact a large, strong person, fifty-one years old, who did a lot of farm work as a boy, who is good with tools. I have raised six children, three my own and three adopted. They have all turned out well. Two of them are farmers. I am a combat infantry veteran from World War II, and hold a Purple Heart. I have earned whatever I own by hard work. I have never been arrested or sued for anything. I am so much trusted with young people and by young people that I have served on the faculties of the University of Iowa, Harvard, and the City College of New York. Every year I receive at least a dozen invitations to be commencement speaker at colleges and high schools. My books are probably more widely used in schools than those of any other living American fiction writer.

If you were to bother to read my books, to behave as educated persons would, you would learn that they are not sexy, and do not argue in favor of wildness of any kind. They beg that people be kinder and more responsible than they often are. It is true that some of the characters speak coarsely. That is because people speak coarsely in real life. Especially soldiers and hardworking men speak coarsely, and even our most sheltered children know that. And we all know, too, that those words really don’t damage children much. They didn’t damage us when we were young. It was evil deeds and lying that hurt us.

After I have said all this, I am sure you are still ready to respond, in effect, “Yes, yes–but it still remains our right and our responsibility to decide what books our children are going to be made to read in our community.” This is surely so. But it is also true that if you exercise that right and fulfill that responsibility in an ignorant, harsh, un-American manner, then people are entitled to call you bad citizens and fools. Even your own children are entitled to call you that.

I read in the newspaper that your community is mystified by the outcry from all over the country about what you have done. Well, you have discovered that Drake is a part of American civilization, and your fellow Americans can’t stand it that you have behaved in such an uncivilized way. Perhaps you will learn from this that books are sacred to free men for very good reasons, and that wars have been fought against nations which hate books and burn them. If you are an American, you must allow all ideas to circulate freely in your community, not merely your own.

If you and your board are now determined to show that you in fact have wisdom and maturity when you exercise your powers over the eduction of your young, then you should acknowledge that it was a rotten lesson you taught young people in a free society when you denounced and then burned books–books you hadn’t even read. You should also resolve to expose your children to all sorts of opinions and information, in order that they will be better equipped to make decisions and to survive.

Again: you have insulted me, and I am a good citizen, and I am very real.

Kurt Vonnegut

My Most Illustrious Lord,

Having now sufficiently seen and considered the achievements of all those who count themselves masters and artificers of instruments of war, and having noted that the invention and performance of the said instruments is in no way different from that in common usage, I shall endeavour, while intending no discredit to anyone else, to make myself understood to Your Excellency for the purpose of unfolding to you my secrets, and thereafter offering them at your complete disposal, and when the time is right bringing into effective operation all those things which are in part briefly listed below:

1. I have plans for very light, strong and easily portable bridges with which to pursue and, on some occasions, flee the enemy, and others, sturdy and indestructible either by fire or in battle, easy and convenient to lift and place in position. Also means of burning and destroying those of the enemy.

2. I know how, in the course of the siege of a terrain, to remove water from the moats and how to make an infinite number of bridges, mantlets and scaling ladders and other instruments necessary to such an enterprise.

3. Also, if one cannot, when besieging a terrain, proceed by bombardment either because of the height of the glacis or the strength of its situation and location, I have methods for destroying every fortress or other stranglehold unless it has been founded upon a rock or so forth.

4. I have also types of cannon, most convenient and easily portable, with which to hurl small stones almost like a hail-storm; and the smoke from the cannon will instil a great fear in the enemy on account of the grave damage and confusion.

5. Also, I have means of arriving at a designated spot through mines and secret winding passages constructed completely without noise, even if it should be necessary to pass underneath moats or any river.

6. Also, I will make covered vehicles, safe and unassailable, which will penetrate the enemy and their artillery, and there is no host of armed men so great that they would not break through it. And behind these the infantry will be able to follow, quite uninjured and unimpeded.

7. Also, should the need arise, I will make cannon, mortar and light ordnance of very beautiful and functional design that are quite out of the ordinary.

8. Where the use of cannon is impracticable, I will assemble catapults, mangonels, trebuckets and other instruments of wonderful efficiency not in general use. In short, as the variety of circumstances dictate, I will make an infinite number of items for attack and defence.

9. And should a sea battle be occasioned, I have examples of many instruments which are highly suitable either in attack or defence, and craft which will resist the fire of all the heaviest cannon and powder and smoke.

10. In time of peace I believe I can give as complete satisfaction as any other in the field of architecture, and the construction of both public and private buildings, and in conducting water from one place to another.

Also I can execute sculpture in marble, bronze and clay. Likewise in painting, I can do everything possible as well as any other, whosoever he may be.

Moreover, work could be undertaken on the bronze horse which will be to the immortal glory and eternal honour of the auspicious memory of His Lordship your father, and of the illustrious house of Sforza.

And if any of the above-mentioned things seem impossible or impracticable to anyone, I am most readily disposed to demonstrate them in your park or in whatsoever place shall please Your Excellency, to whom I commend myself with all possible humility.

I always wondered where Sam Spade's office was.

Biewald actually served as CEO for most of its history, but in August of last year, Woody Hobbs was named CEO, and Biewald stepped down to become executive chairman (a job that seemed to mostly involve evangelizing for CrowdFlower, while also building iPhone apps as a hobby).

Biewald (who I lived with briefly in college) tells me the decision to take back his old job is relatively recent, and that he pitched the board of directors on a return to the company’s roots. CrowdFlower started out as a self-service product, which Biewald says has “stagnated” as the company focused on enterprise sales: “That was a little bit frustrating to watch.”

That doesn’t mean CrowdFlower will ignore enterprise customers, Biewald says — he just doesn’t want to pursue them using the traditional sales model. He points to Jigsaw and Box.net as examples he wants to follow, particularly the way they’re able to serve large and small customers without a huge salesforce.
