Economics is mostly theory about how the world should operate based on certain laws... supply and demand etc. They go through rigorous derivations using calculus and statistics. You might get a top level overview of the driving forces behind an industry, but in a startup that's hardly useful.
Also in microeconomics, you are taught how a prototypical consumer might behave under canned conditions. Not at all representative of the real world.
There's really a single law book for running startups, and the first commandment is talk to your customers. Literally everything else is bs, at least in the beginning stages.
The human brain and our tools thus far are more adapted to solving linear problems, so the higher the dimensionality and non-linear the relationships, the less we're able to produce determinist results.
I personally believe problems of this kind we cannot arrive at perfect solutions, only optimal ones. By optimal, I mean making trade-offs on certain variables so as to minimize total cost. The weights are also variables depending on trends of the epoch (environmental factors not such a big deal a decade ago, big deal now --> need to update our equation)
The other factor comes as a form of bureaucracy. It takes time to push the change through the chain of politics, re-aligning incentives, carving new markets and distribution channels, changing market sentiments, etc.
Ask HN: I'm less productive with TDD. Am I doing it wrong?
Hi guys,I've been programming for about four years now. I was taught on the job by a friend, and I've always learned to make one small piece before connecting everythingFor example, if I need to make a simple 2D game, I put together the rendering function, then a separate function for handling key-events etc.The gist is that I don't really have a blueprint on paper, it's all in my head, the...
Spread of a single multidrug resistant malaria parasite lineage to Vietnam
Ages on ages before any eyes could see year after year thunderously pounding the shore as now. For whom, for what? On a dead planet with no life to entertain.
Never at rest tortured by energy wasted prodigiously by the Sun poured into space. A mite makes the sea roar.
Deep in the sea all molecules repeat the patterns of one another till complex new ones are formed. They make others like themselves and a new dance starts. Growing in size and complexity living things masses of atoms DNA, protein dancing a pattern ever more intricate.
Out of the cradle onto dry land here it is standing: atoms with consciousness; matter with curiosity.
Stands at the sea, wonders at wondering: I a universe of atoms an atom in the Universe.

Can I get into a respectable CS masters program with a Math and Physics degree?
Hi guys,I was planning on majoring in CS + Physics, but the introductory course for CS is really turning me off. I'm interested in machine learning, which I believe is mostly graduate work. I was wondering if I can do my undergrad in math & physics and still get into a respectable program (say tier 1 schools) to learn about ML
Being the dumbest guy in the room, and knowing so is probably good for you in the long run.
Ask HN: AI / ML Researchers, is AI a threat or not?
I'm have some CS training and have worked in the fringes of AI, but nothing deeply theoretical. Really smart people have occupied both sides of the argument, and I'm not sure who to believe.The most viable argument I've heard for it is the difficulty in providing all possible constraints to narrow the path of optimization (so as to accommodate human norms). I.e. Facebooks negotiating bot...
Is SEO still important for apps?
I'm trying to pick a name for my app. All the composite words I can think of are taken, which leaves me with generic words like Flare and Fable. It's not a big deal in the app store if I decide to do so.I was wondering what if it would be detrimental if I got a domain like getflare.com (just an example, it's actually not available) or should I keep thinking of a unique word pair?
Substance is overwhelmingly like a self-improvement article, cherrypicking details to support whatever point the author stands to posit.
Do people really pay for news?
Is there a revenue modal for news that appeals to users? I hear a lot of complaints, including from PG, that subscriptions are a pain to manage, yet it is the most widely used.Would a pay-per-article work better or would it repel users?
I experience difficulty with task switching. When I latch onto a problem, I feel like I cannot do anything else until that problem is solved. This makes for very inefficient studying as often I just need time to digest. This also creates problems for multi-tasking.
What I find strange is that I have much less of a task switching problem when it comes to programming.
As others have pointed out, will-power comes and goes with energy levels. On afternoons I'm practically useless. In my experience the disparity between what one wants to do and what one ends up doing is function of available energy, as a form of mental agility.

Ask HN: Are there working content models where price is linked to quality?
Ie We pay the same price for crappy books as we do for classics; same goes for movies.Are there any models where price paid by the consumer is attributed to quality rather than distribution?
AI doesn't need to exceed humans in every dimension to become a threat. Just sufficient dimensions.
Humanity is basically a bacteria colony in a petridish with I/O. Disrupt infrastructure, and you disrupt input leading to changes in the size of the colony. And mind you, much of our infrastructure resides in the cloud.
Of course, It will be a while before this even becomes an issue, but this is basically how a machine would frame the problem.
Implementation wise, AI doesn't need to be general. At its most inelegant (and not too distant) design, ML can be configured as a fractal of specific of algorithms, with one on top with the task of designating goals and tasks, and subordinates spawning off generations and evaluating performance.
Andy Grove had a good saying, "anything can be done will be done"
Autonomous AI, if it does not break the laws of physics, will exist. It's development will be spurred by our curiosity or profit.
