<p>This is not  about employer vs employee and job security. In fact, the post mentions that there could be good reasons for layoffs. What the post highlights is -<p>1. Trust - When an employer tells the employee something and then ignores it - then a truth based culture gives in to cynicism. Communications in the company become suspect. Even when there are win-win situations, where cooperation could lead to positive outcomes for both management and workers, a lack of trust means the company cant execute.<p>Also, this will affect communications with customers and shareholders.<p>2. Regardless of being right, the author is helping others in similar situations, who can adjust their expectations.<p>3. The post isn't so much about company vs employee, but competing factions within the company, who are invested in alternative tools/proposals. Promotion is used as a means of making one's faction stronger. This need not be for the benefit of the company or customers. Lobbying will also, of course, affect truth.<p>Factions might be inevitable (and there can even be good reasons - people genuinely have differences of opinion). But, if the company has good leaders, they will prevent this from erupting into a strong zero-sum conflicts which drown other goals - company's profits, promoting competent people, a culture of trust.</p>

(2019)"]]></title><description><![CDATA[
<p>There is a purely geometric reason for why elliptic curves have group structure. A geometric shape which is also a group, such that the group operations are smooth maps,  has to be homogeneous - it has to look the same from every point[1]. Not just that, if you have a vector at some point, there is a natural way to transport it to every other point on the shape. The only surface (curves over complex numbers are really 2d surfaces) which obeys this property is the torus[2].<p>[1] Why should the homogeneous property be true? Because in a group, multiplication by g, pushes the identity e to g.  M_g(e)=g where. This is a continuous isomorphism of the shape. So the shape looks the same at g as it looks at a (a neigbhourhood of g looks the same as neighbourhood of e). So an 'X' or 'Y' shapes cant be groups, as there are points which are locally unique, but 'O' shape can be a group. Moreover, M_g can also push a fixed non-zero vector v at e to a vector v_g at g.<p>[2] The Euler characteristic of the torus is 0. A non-zero vector field has index 0. <a href="https://en.wikipedia.org/wiki/Poincar%C3%A9%E2%80%93Hopf_theorem" rel="nofollow">https://en.wikipedia.org/wiki/Poincar%C3%A9%E2%80%93Hopf_the...</a>

<p>For someone new, this was a really interesting read. Thanks for the effort. The picture of how the sky looks from underwater was so surprising to learn.<p>Regarding the 'first-principles' discussion, it is a relative term in usage despite the name. Explaining from a layer of abstraction below normal explanations.<p>Someone explaining how a computer works starting with machine instructions is doing first-priniciples, even if they wont explain details of atoms. The literal meaning would be almost impossible to implement, for instance  none of Newton's work would be first principles given today's knowledge. Similarly, current physics can be subsumed in future principles.</p>

<p>There is an important difference between Atman and Soul. Thoughts, emotions, decisions are  seen as part of nature/prakriti not Atman,  whereas Soul is usually intended to include these things.<p>A better description would be that the atman is the consciousness in which physical things or mental constructs can appear and pass away. The nature of pure consciousness is also described as real(undisturbed by time) or ananda/contentment/bliss.<p>The disidentifcation from thoughts (for instance, seeing them pass by just like cars on road) is an important part of liberation.</p>

<p>Sure, as long as your real world examination is careful about getting the causation right as practically any idea can be appropriated. For instance, someone makes false charge to lock up someone innocent in the name of 'reducing crime', is the issue the goal of justice and low crime or is it the problem with the standards of evidence used to lock up the criminal?</p>

<p>Quoting examples without an effort to show that it is representative of Buddhist teachings is basically a smear. Like starting a discussion on liberalism, not with principles of individual freedom, but instead saying that the attempt to bring democracy to Iraq is the representative example of liberalism.<p>(Some on the left who oppose liberalism actually do some versions of this, quoting Mills on colonialism - but that is a genetic fallacy.)<p>It makes much more sense to say that anytime some teaching/philosophy becomes popular at a continental scale, the people who are involved in conflicts will try to appropriate it to justify their position.<p>If you want to evaluate the role of the teaching itself, one would have to compare it to alternatives and whether they would be more easily appropriated.</p>

<p>> we can keep on building theorems on top of theorems with increasing complexity<p>This is a somewhat bleak picture of math. We also have the other phenomena of increasing simplicity. Both statements and proofs becoming more straightforward and simple after one has access to deeper mathematical constructions.<p>For example : Bezout's theorem would like to state that two curves of degree m, degree n would intersect in mn points. Except that you have two parallel lines intersecting at 0 instead of 1.1 =1 point, two disjoint circles intersect at 0 instead of 2.2=4 points, a line tangent to a circle intersecting at 1 point instead of 1.2=2 points. These exceptions merge into a simple picture once one goes to projective space, complex numbers and schemes. Complex numbers  lead to lots of other instances of simplicity.<p>Similarly, proofs can become simple where before one had complicated ad-hoc reasoning.<p>Feynman once made the same point of laws of physics where in contrast to someone figuring out rules of chess by looking at games where they first figure out basic rules(how pieces move) and then moves to complex exceptions(en passant, pawn promotion), what often happens in physics is that different sets of rules for apparently distinct phenomena  become aspects of a unity (ex: heat, light, sound were seen as distinct things but now are all seen as movements of particles; unification of electricity and magnetism).<p>Of course, this unification pursuit is never complete. Mathematics books/papers constantly seem to pull a rabbit out of a hat. This leads to 'motivation' questions for why  such a construction/expression/definition was made. For a few  of those questions, the answer only becomes clear after more research.</p>

<p>Cutting off water supply is clearly the bigger threat. However, it involves a longer time frame - building infrastructure which one expects not to use in a normal situation.<p>Importantly, even once built, it selects the wrong targets, not terrorists or  military bases - but regular people who will be faced with scarcity of water and food, as the crops use Indus water. This would be something highly unethical, and also not something sustainable - once visuals of hunger start reaching screens across the world, the force to restart the supply would be strong.</p>

<p>Yes, an outside target can be used to tackle internal strife. But, there is no sign that the Pakistani army is actually in any danger of being removed from power, barring a major military defeat, nor that it will lose its autonomy over military policy.<p>If say, India were to let this slide, the default outcome is another such attack. Given the above motivation of the military to create a conflict and the ideological bent seen in Gen.Munir's speech, the expected outcome would be to repeat till this they get a conflict.<p>Yes, the deterrence won't be perfect. The Pakistan Army might end up repeating an attack whenever there is a relief from economic constraints(it doesn't have money for frequent purchases of expensive weapons) or from pressure from its allies (who dont want their oil trade or pipelines to suffer). But this means that what India has to do to minimize the number of attacks is to not let an attack slide by with low cost for the army.<p>The best case scenario would be a peace deal, as was arrived in Vajpayee and Sharif's time, but it was sabotaged by the Kargil operation, for exactly the reason you mentioned - a peace deal marginalises the army.</p>

<p>We are not talking about re-targeting of training and weapons from Afghanistan to Manhattan, but direct planning of an attack with ability to restrain and release the groups on demand. Contra the truthers, even the CIA wouldn't go that far. Musharraf explicitly mentioned the groups operating in Kashmir. He wasn't talking about fighters in Afghanistan.</p>

<p>The context was a reply to an assertion that the terrorists in Pahalgam were not found by Indian security. I interpreted this as people who physically did the attack.<p>If by terrorists, we mean the planners of the operation, that trail leads directly to Pakistan. Musharraf, the ex-army chief, is on record saying that the military has funded several militant organizations in Kashmir including LeT. (Osama's haveli in Abbotabad was incidentally also very close to the Pakistan Military Academy). The permission for the operations probably came all the way from the top as the attack came right after a strong statement on Kashmir by the army chief.</p>

<p>The incentives of the Pakistani generals to permit organizations like LeT to commit further terrorist attacks is a different domain from whatever the local political situation is like in India. There has been a past regime where Pakistani generals were able to train and send militants regularly to conduct terror attacks in India. Without an effective response from India putting pressure on these generals, that can easily become the new normal again.</p>

<p>If you are actually arguing that a country targeted by a terrorist attack does not gain deterrence with a counterstrike relative to letting things go on, then how uniform do you consider this prescription? Should the terror attacks in the US or France <i>not</i> have had a military response?<p>What happens to the incentives of terror groups in response to such a policy?<p>---<p>The role of money only becomes an issue when conducting a terrorist attack becomes expensive. Missiles and jets consume much more money in comparison to training recruits via an intermediary organization like LeT and sending them across the border to carry out attacks.<p>A regime in which a terror attack leads to a high pressure, expensive situation for the Pakistani military is completely different from regularly scheduled, train and deploy terror attacks from militants which used to happen earlier.<p>In that situation, the military has to respond to economic pressure, pressure from allies <i>and</i> pressure from its own people.</p>

<p>> They were unable to locate the terrorists even after two or three weeks and needed a distraction.<p>This does not make sense. When France attacked Daesh in 2015 after the terrorist attacks in Paris or when the US attacked Afghanistan after 9/11, the objective wasn't to target the exact people who carried out the attacks, but the organization behind the attacks. People can always be found as long as the organization remains.<p>The goal of the attacks would be to make any future terrorist attack an expensive option for the Pakistani military as opposed to something which can be done routinely. There was a sharp drop in the terrorist attacks in Kashmir after the 2019 confrontation.</p>
