Neat sites: The OTA Legacy

The Office of Technology Assessment was one of the most fascinating historical institutions in the U.S. Their complete reports are preserved online thanks to the dedication of some folks at Princeton. Some of the reports are still relevant some quarter+ century later and are of the highest level of quality out of all publicly available information.

Short Interview with William Shockley (1969)

Dr. Shockley invented the transistor design that wound up in mass produced electronics in December, 1947. Quite worth the ~7 minutes to take a look:

Notably he speculates on flat screen displays as an off-hand remark, in 1969! Those folks at Bell Labs were a generation ahead of their time.

Do Bacteria make decisions?

Every now and then I come across a great Quora post.

This one contains a great answer to a somewhat esoteric topic, that of bacteria motion. It’s worth a read.

The short answer is yes, if you define decision making for bacteria as reliably selecting, out of various alternatives, one committed trajectory.

Review: Dyson Lightcycle Morph

Rating: 3 out of 5.

Useful, with unavoidable flaws

Really cool technology and design with a few annoying downsides, perhaps a replacement+ for your halogen lamp

Major merits

Very snappy magnetic action, perfectly smooth, also fun!

Painless setup

Heavy base that will absolutely not shift around

Color temp., brightness, and motion, automation

App not even needed for most functionality


Minor merits

7.5 W USB-C charger

No WiFi – one less smart thing to worry about securing

very minimal branding, can be easily covered

Minor flaws

Colour rendering slightly less than halogen lamp equivalent

No detailed lighting specifications available

Cheap black plastic base underside

External power adaptor

Major flaws

Bizzare warranty and service scheme in Canada – 2 years only, compared to 5 years in the US – only spare parts available are the power supply and cable

Black components on the otherwise all White/Silver colour option that also add a functional flaw -overheating of the lamp seperator/cover – be careful not to touch it after a long session!

Too easy to trigger touch controls accidentally

Summary thoughts

Dyson tries really hard to be the Apple of small home appliances, they get close in certain aspects but in other ways fall quite short. For example, the cheap black plastic, that add an otherwise easily avoidable functional flaw to the lamp, which also replicates the major downside of the halogen lamps its designed to replace, is really indicative of something go wrong with their design process. Why was this kind of decision made? to save a few pennies on the BOM of a luxury lighting fixture? And touted to last for 60+ years no less… Perhaps Dyson will improve on these shortcomings for the next model.

Cool Essays: Adventurer #45, The difficulty of forming confederacies

Considering that this was written in 1753 by Samuel Johnson in his mid forties, the incisive observations are still remarkably stunning and the points addressed are especially noteworthy. One of his best essays.

Nulla fides regni sociis, omnisque potestas
Impatiens consortis erit.
—LUCAN. Lib. i. 92.

  No faith of partnership dominion owns:
Still discord hovers o’er divided thrones.

It is well known, that many things appear plausible in speculation, which can never be reduced to practice; and that of the numberless projects that have flattered mankind with theoretical speciousness, few have served any other purpose than to show the ingenuity of their contrivers. A voyage to the moon, however romantick and absurd the scheme may now appear, since the properties of air have been better understood, seemed highly probable to many of the aspiring wits in the last century, who began to dote upon their glossy plumes, and fluttered with impatience for the hour of their departure:

   —Pereunt vestigia mille
Ante fugam, absentemque ferit gravis ungula campum.

  Hills, vales and floods appear already crost;
And, ere he starts, a thousand steps are lost. POPE.

Among the fallacies which only experience can detect, there are some, of which scarcely experience itself can destroy the influence; some which, by a captivating show of indubitable certainty, are perpetually gaining upon the human mind; and which, though every trial ends in disappointment, obtain new credit as the sense of miscarriage wears gradually away, persuade us to try again what we have tried already, and expose us by the same failure to double vexation.

Of this tempting, this delusive kind, is the expectation of great performances by confederated strength. The speculatist, when he has carefully observed how much may be performed by a single hand, calculates by a very easy operation the force of thousands, and goes on accumulating power till resistance vanishes before it; then rejoices in the success of his new scheme, and wonders at the folly or idleness of former ages, who have lived in want of what might so readily be procured, and suffered themselves to be debarred from happiness by obstacles which one united effort would have so easily surmounted.

But this gigantick phantom of collective power vanishes at once into air and emptiness, at the first attempt to put it into action. The different apprehensions, the discordant passions, the jarring interests of men, will scarcely permit that many should unite in one undertaking.

Of a great and complicated design, some will never be brought to discern the end; and of the several means by which it may be accomplished, the choice will be a perpetual subject of debate, as every man is swayed in his determination by his own knowledge or convenience. In a long series of action some will languish with fatigue, and some be drawn off by present gratifications; some will loiter because others labour, and some will cease to labour because others loiter: and if once they come within prospect of success and profit, some will be greedy and others envious; some will undertake more than they can perform, to enlarge their claims of advantage; some will perform less than they undertake, lest their labours should chiefly turn to the benefit of others.

The history of mankind informs us that a single power is very seldom broken by a confederacy. States of different interests, and aspects malevolent to each other, may be united for a time by common distress; and in the ardour of self-preservation fall unanimously upon an enemy, by whom they are all equally endangered. But if their first attack can be withstood, time will never fail to dissolve their union: success and miscarriage will be equally destructive: after the conquest of a province, they will quarrel in the division; after the loss of a battle, all will be endeavouring to secure themselves by abandoning the rest.

From the impossibility of confining numbers to the constant and uniform prosecution of a common interest, arises the difficulty of securing subjects against the encroachment of governours. Power is always gradually stealing away from the many to the few, because the few are more vigilant and consistent; it still contracts to a smaller number, till in time it centres in a single person.

Thus all the forms of governments instituted among mankind, perpetually tend towards monarchy; and power, however diffused through the whole community, is, by negligence or corruption, commotion or distress, reposed at last in the chief magistrate.

“There never appear,” says Swift, “more than five or six men of genius in an age; but if they were united, the world could not stand before them.” It is happy, therefore, for mankind, that of this union there is no probability. As men take in a wider compass of intellectual survey, they are more likely to choose different objects of pursuit; as they see more ways to the same end, they will be less easily persuaded to travel together; as each is better qualified to form an independent scheme of private greatness, he will reject with greater obstinacy the project of another; as each is more able to distinguish himself as the head of a party, he will less readily be made a follower or an associate.

The reigning philosophy informs us, that the vast bodies which constitute the universe, are regulated in their progress through the ethereal spaces by the perpetual agency of contrary forces; by one of which they are restrained from deserting their orbits, and losing themselves in the immensity of heaven; and held off by the other from rushing together, and clustering round their centre with everlasting cohesion.

The same contrariety of impulse may be perhaps discovered in the motions of men: we are formed for society, not for combination; we are equally unqualified to live in a close connexion with our fellow-beings, and in total separation from them; we are attracted towards each other by general sympathy, but kept back from contact by private interests.

Some philosophers have been foolish enough to imagine, that improvements might be made in the system of the universe, by a different arrangement of the orbs of heaven; and politicians, equally ignorant and equally presumptuous, may easily be led to suppose, that the happiness of our world would be promoted by a different tendency of the human mind. It appears, indeed, to a slight and superficial observer, that many things impracticable in our present state, might be easily effected, if mankind were better disposed to union and co-operation: but a little reflection will discover, that if confederacies were easily formed, they would lose their efficacy, since numbers would be opposed to numbers, and unanimity to unanimity; and instead of the present petty competitions of individuals or single families, multitudes would be supplanting multitudes, and thousands plotting against thousands.

There is no class of the human species, of which the union seems to have been more expected, than of the learned: the rest of the world have almost always agreed to shut scholars up together in colleges and cloisters; surely not without hope, that they would look for that happiness in concord, which they were debarred from finding in variety; and that such conjunctions of intellect would recompense the munificence of founders and patrons, by performances above the reach of any single mind.

But discord, who found means to roll her apple into the banqueting chamber of the goddesses, has had the address to scatter her laurels in the seminaries of learning. The friendship of students and of beauties is for the most part equally sincere, and equally durable: as both depend for happiness on the regard of others, on that of which the value arises merely from comparison, they are both exposed to perpetual jealousies, and both incessantly employed in schemes to intercept the praises of each other.

I am, however, far from intending to inculcate that this confinement of the studious to studious companions, has been wholly without advantage to the publick: neighbourhood, where it does not conciliate friendship, incites competition; and he that would contentedly rest in a lower degree of excellence, where he had no rival to dread, will be urged by his impatience of inferiority to incessant endeavours after great attainments.

These stimulations of honest rivalry are, perhaps, the chief effects of academies and societies; for whatever be the bulk of their joint labours, every single piece is always the production of an individual, that owes nothing to his colleagues but the contagion of diligence, a resolution to write, because the rest are writing, and the scorn of obscurity while the rest are illustrious.
