<p>It's about fitting your utilization to the model that best serves you.<p>If you can keep 4 "Java boxes" fed with work 80%+ of the time, then sure EC2 is a good fit.<p>We do a lot of batch processing and save money over having EC2 boxes always on.  Sure we could probably pinch some more pennies if we managed the EC2 box uptime and figured out mechanisms for load balancing the batches...  But that's engineering time we just don't really care to spend when ECS nets us most of the savings advantage and is simple to reason about and use.</p>

When it's decided that something actually needs to pass, then you'll get some sacrificial lambs that vote across the aisle.  Typically they'll be close to retirement or from a state where they won't be heavily punished for that specific vote.</p>

<p>It's like bike shedding.  It's a side effect of mixed expertise (and confidence) working together on things that are only partially understood by all.  When something is clearly outside one's expertise, they are content to leave it to others.  But then you'll get minor questions with low stakes like "what color to paint the shed".  And how everyone feels like they can participate, so suddenly there's a huge discussion / debate / argument about a very, very minor thing.</p>

<p>I was part of an ACM programming team in college.  We would review classes of problems based on the type of solution necessary, and learn those techniques for solving them.  We were permitted a notebook, and ours was full of the general outline of each of these classes and techniques.  Along with specific examples of the more common algorithms we might encounter.<p>As a concrete example, there is a class of problems that are well served by dynamic programming.  So we would review specific examples like Dijkstra's algorithm for shortest path.  Or Wagner–Fischer algorithm for Levenshtein-style string editing.  But we would also learn, often via these concrete examples, of how to classify and structure a problem into a dynamic programming solution.<p>I have no idea if this is what is meant by "l33t code solutions", but I thought it would be a helpful response anyway.  But the bottom line is that these are not common in industry, because hard computer science is not necessary for typical business problems.  The same way you don't require material sciences advancements to build a typical house.  Instead it flows the other way, where advancements in materials sciences will trickle down to changing what the typical house build looks like.</p>

<p>My guess would be lack of actuators.  For instance, this robot looks like it has an ankle that can only go up and down, but not roll like a human's.  Also, I wonder if there's a center of gravity issue, as it almost always appears to be leaning backwards to even out.<p>I think it's still pretty impressive in its recoveries, even though there's an unnaturally large number of them necessary.  About 8 seconds into the video on the homepage, it almost misses and ends up slipping off the second step.  I've eaten shit at missing a couple inch curb, though I don't think "graceful" has ever been used as a descriptor for me.  So the fact that it just recovers and keeps going without issue is impressive to me.</p>

<p>I'm not familiar with any of these communities.  Is there also a general bias towards one side between "the most important thing gets the *<i>most*</i> resources" and "the most important thing gets *<i>all*</i> the resources"?  Or, in other words, the most important thing is the only important thing?<p>IMO it's fine to pick a favorite and devote extra resources to it.  But that turns less fine when one also starts working to deprive everything else of any oxygen because it's not your favorite.  (And I'm aware that this criticism applies to lots of communities.)</p>

<p>That only works if the external API is handing off the entire subscription to Apple, up to and including payments.  But the entire premise is to move away from being forced to use Apple for these elements, which makes it a non-sensical interpretation.  In fact, that particular interpretation is the current status-quo -- apps use APIs to create subscriptions entirely managed by Apple.<p>If Apple does not control the actual subscription, but is only providing an interface for managing it, then Apple must then alert the actual owner of the subscription upon changes.  There's then no guarantee that the code on the other side is properly handling that alert.</p>

<p>This is classic correlation is not causation.  The thing about correlation is that it could be a causative relationship, or there could be another set of untracked variables that's causing some or all the effects, or it could be unrelated coincidence.<p>Now, maybe this is a difference between the study and the article.  Maybe the study makes stronger claims here than the article does.  But I didn't see anything in the article that claimed nor demonstrated causation, only correlation.</p>

<p>I mostly agree, but wanted to nit on this point:<p>> hell even big operations like a heart transplant or C-section are rarely done "in the moment."<p>Agree on the plannability, but not on the predictability.  Once you are on that table, and especially if you are under anesthesia, there are an untold number of ways that procedure can quickly turn into a secondary emergency procedure.  It's a miracle of modern medicine that such invasive procedures are perceived as being trivial.</p>
