In my opinion (the market clearly disagrees with me), the mid-2012 15" model was the last great Macbook Pro that Apple ever made. That they don't make the unibodies any more is pretty much the main reason why I went back to a PC laptop.

I loved my 2011 MBP because I didn't have to pay Apple prices for RAM and storage, and was gradually able to upgrade it as prices for RAM and SSDs came down. That was until it got bricked by the famous GPU overheat issue.

By the time Apple finally acknowledged and started fixing the problem, I had already switched away.

The Retina MBPs are nice, but thin for thinness' sake did not align with what I wanted. I would have rather they put in a bigger battery in the unibodies instead of shrinking the body.
"Yet" is the keyword. I said "most to prove" not "headed to the Unicorn grave."
My point is that social companies have the most to prove when it comes to their valuations (lots of users but questionable rev), and especially with Facebook eating everyone's lunch, I think investors will start ramping up the pressure on Pinterest (and Snapchat) for real revenue growth.

At least Snapchat has gotten much more serious about experimenting with ads. Pinterest is still in this early Facebook stage of "we don't really care about making money right now," which I don't think really flies anymore for a company of that stage.

If you're talking about time in the science and engineering domains, you're supposed to represent your quantity using a tasteful unit of your choosing.

* Scientists and engineers culturally select tasteful units of their choice to represent time, like 1300 milliseconds or 134 hours... and everything else as well: $1.34 billion or $1.34 dollars, not $1 billion and 340 million or $1 dollar and 34 cents.

* When the number representation get too big, people just do X * 10^n where n is a tasteful choice.

* In business, days and hours are distinct concepts and should not be mixed together or confused. A person who worked for 5 days did not work 120 hours.

* Mathematicians could care less.

* Many culturally common units of time are bigger than 12 * 12.

* Calculations that are big are working-memory bound. This is the biggest point. Working memory is probably the strongest factor to large and fast calculation of any kind.

* The bigger the calculation, the more people tend to 10^n multiplicands with the distributive property, rather than 12^n, since most people work in base 10. Some engineers use 2^n or 3^n (I offer that 3^n is efficient without further explanation).

I propose the hypothesis that children who memorized up to 10 * 10 are no more likely to join or do well in the STEM fields than those who memorized up to 12 * 12.

I'm an American who has lived in Russia for a few years. I speak Russian fluently as second language. I've discussed this topic in depth with Russians from various backgrounds.

I think that your point ("People who lived in communist Russia will often tell you that people were happier under communism") is unsubstantiated. I've heard this a FEW times, but mostly from older (60+) unskilled laborers (like taxi drivers) who are simply unable to adjust to the new world.

Almost all Russians realize that their country is better until capitalism. (If you want to call what they have here 'capitalism', it's more like 'crony capitalism').

Nor do I agree with "It is human nature to want equality". Humans will always jockey for status and power. That is human nature. If it can't be done with money, then they will use whatever other kind of social 'currency' exists to try to rise in the hierarchy of status... just like the pigs in 'Animal Farm'... or communist party leaders in the Soviet Union.

Mostly, people are who complaining about inequality are really complaining that they ended up at the bottom of the hierarchy and have how no clue how to or no willingness to climb it.
This isn't a drug you just jump right into. If you're interested in nootropics, it's smarter to test the waters with simple stuff like choline (preferably in the form of citicoline of alpha GPC) and ALCAR (acetyl L-Carnitine), then slowly considering a racetam like piracetam or noopept.

No, it's you who are mistaken. The posterior is not remotely like idea averaging.

Idea averaging is about taking multiple ideas and merging them into one. The Bayesian posterior is merely assigning probabilities to each individual idea. I.e., idea averaging is "knife + spoon = spoon with sharp edge". Bayesian posterior is "50% knife is best, 50% spoon is best => evidence => 5% knife is best, 95% spoon is best".

The latter is what the article is saying we should do; don't build a new idea incorporating everyone's contributions, instead just figure out which individual idea is the best and do it.

His argument about the 'Unix Philosophy' reminds me a lot of the argument between using big web frameworks like Django vs smaller micro-frameworks like Flask. Personally, I prefer Flask for the small projects I make because of how nimble it is but it's hard to argue with the large organizations using Django for massive projects to (seemingly) good effect. Ironic since I actually do like Angular (sorry)!

Overall I felt the article was preachy and extremely biased. It's as if the author was trying really hard to convince as opposed to just presenting the facts and letting the reader make a choice based on the evidence.

I have concerns about ng2 but having made an effort to learn React as well I think he dramatically oversimplifies it's ease of use for large scale projects (where Angular shines, IMHO).

What? It's not a learning opportunity. It makes me uncomfortable because it looks like it's racist. There's nothing to introspect there.

And it looks like it's racist because, honestly, it is actually a little racist. Don't get me wrong, after reading about Comodo I get why they went with Arabic names, but that doesn't mean it's not still racist. The actual satire could have worked without the racism, and yes, racism can be funny in the right contexts. But none of that means that it's not actually racist at some level. And it's better to acknowledge that, yes, it's a little racist, than it is to try and claim that it's not.
I did that drive bay caddy thing on my 2011 MBP for a while. That setup ate battery like you wouldn't believe. I could barely get 2 hours of time on it.

Thankfully, SSD prices dropped significantly and I ended up replacing both drives with a 1TB SSD and sticking the optical back into it.

There promo videos seems to promise way more than they showed off on stage. I was expecting something along the lines of a vehicles service you subscribe to and whenever you need it, this autonomously driving van with interior akin to a Rolls shows up and takes you to your destination. That was the impression I was getting. What they have I feel is a nice idea for a platform to make lots of different models with interior features described with adjectives they obviously learned by watching Jony Ive speak. They compare themselves to Apple in 2007, but I think there vision is all over the place. Its fairly complex. The thing that made Apple so successful is that they had one particular product to really focus on and its scope was really focused, which enabled them to hit it out of the park. Here however, they have a million different things they are trying to hone the scope on. They definitely seem extremely optimistic and checking on LinkedIn, there boasting about the quality of there employees does seem to stack up. I am looking forward to some comments of Elon Musk.

I agree with you. A product manager doesn't need to be a great developer - they just need sufficient experience with development to assess the impact and complexity of changes, and to better understand where there might be opportunities. You have that plus passion for the role, which is a rare combination. Hopefully your employer recognizes the value of it!

Blackboard Replaces CEO Jay Bhatt: What Happened
"Not for routine costs" and "high deductible" are hardly the same thing. You can conceivably have a $0 deductible for treatment and no coverage for routine prevention. Thus, you pay nothing when you break your arm- it was unlikely and unexpected- and you pay full cost for checkups.

(Of course, that creates a bit of a perverse incentive, nudging you to skip preventative care and lean on treatment)
I did at a large firm. They even had a no-remote policy at the time.

I asked my boss to do a one month test, one day a week working remotely. I documented my production levels for those remote days to prove that my productivity could increase by working at home.

After the month test, I proposed one-week a month and then increased to full-time remote after about three months.

This doesn't come as a surprise. Amazon has created fantastic consumer and merchant experiences and brought buyer friction down to almost nothing.

I'll be interested to see how they plan to tackle the in-store experience. There are obviously the perishable aspects of grocery store products which, with intense and continual establishment of their current strategies, will eventually present opportunity to become a viable part of the company. But on another end of things, shopping as a hobby is something to overcome. No amount of UX or UI (in current stages, at least) can compare to the coveted experience that shoppers seek when going to a mall. This is an area where Amazon might find value in AR. Ex. being able to try on an outfit without leaving your house.

An obvious method would be to open their own physical stores but that would probably just be a "tiller on the car" fix.

Whatever direction the company goes, I look forwards to seeing what Amazon has in store.

I believe 8% annual inflation has been the normal rate for many years -- slightly decreased following ACA enactment, but rates then increased by a few points due to less-healthy enrollees, so it's a bit of a wash (not counting all the people who now have health insurance, to be sure). Premiums also only cover part of the cost increase; higher deductibles and reduced coverage are also used to defray costs, and aren't as obvious to the end consumers. Finally, plans that don't conform to ACA minimum coverage requirements have been killed off, so some individuals are seeing their rates increase commensurate with their improvement in coverage.
> do they deserve the sudden windfall cash that they received? Did the VCs who provided the capital deserve that windfall? Do the workers who actually created a lot of the value in question through their labor get compensated proportionally to the value they built?

And does the owner of capital (investor, banker) deserve the profit (s)he gains? As jivardo_nucci said once on this very forum:

The simulation studies of Bouchard & Mezard show that, regardless of initial conditions, wealth distribution ends up a Pareto distribution with a small percentage taking almost all of the goods. The take-away of Bouchard & Mezard's studies: the very rich aren't rich because they earned it (i.e., because they are skillful or knowledgeable), they are rich mostly because they are lucky.

All my life I've assumed that, when people had a going concern or were rich, that they _earned_ their wealth. But Bouchard & Mezard says they're, for the most part, simply very lucky.

If luck, rather than skill, is the source of one's wealth, then has one "earned" that wealth? How can one lay exclusive claim to something given by chance? I would contend that no such claim can be made.

In particular, I would contend that income gained through luck is fair game for government acquisition through taxation, and if it is possible to distinguish that portion of wealth due to skill from that due to luck (and such appears possible), then the "lucky" portion is open game for acquisition to be spent or redistributed as decided by the powers-that-be.

Yup, basically. Headline was way overstated.
I still think the other comment was mistaken. At a given moment just before drawing a sample from some random variable X, that random variable can have a lot of different possible outcomes. What do I believe X is? I believe X is every different possibility in X's sample space. I simultaneously believe X is a lot of different things. But the degree of belief for each thing is governed by the probability for that outcome being the one I draw. In this sense, my cumulative belief about X is an average of all those different beliefs. That's not the same thing as saying that I have to carry around just one belief that is equal to the posterior mean (or any other point estimate).

> idea averaging is "knife + spoon = spoon with sharp edge". Bayesian posterior is "50% knife is best, 50% spoon is best => evidence => 5% knife is best, 95% spoon is best".

There's a lot wrong with the above quote from your comment. First, you're confounding two very different things. One thing is whether two ideas are mutually exclusive (e.g. the product is fundamentally non-functional if it is a spoon with sharp edge, so blending the two ideas is not in the set of feasible solutions). I already granted in my first comment that genuine mutual exclusivity can be a reason to avoid idea averaging -- but it's just overstated: true mutual exclusivity like that doesn't happen as much as people argue it does.

Secondly, and more importantly, you could break up your budget to pursue the knife solution and the spoon solution independently. What fraction of your budget should you allocate to the knife part? That is, what if 'knife' and 'spoon' are two distinct models that you are considering, and instead of doing crappy model selection to choose merely one of them, you want to produce a model that is a superposition of the two -- what metaprior probability should you choose that the 'knife' model will be the one that succeeds, versus the 'spoon' model?

Maybe something more concrete would be helpful, just think of a Gaussian Mixture Model. You have many different models and you're not choosing just one. You are blending them (and people call this model averaging) by using whatever each different component model's prior probability is to govern what the overall outcome is.

Maybe we are just talking past one another, but I really think the way you keep emphasizing the idea "posterior is a distribution" makes me think you continue to misunderstand me.

Another way to put it is that you are averaging over a space of distributions -- sort of like the Dirichlet distribution. The thing you end up with, the thing that is the result of computing an average, is itself a probability distribution, that comes as an average over a bunch of other probability distributions.
...which I consider a feature, not a bug. It's "insecure" in that I can't lock others out, but no one else can lock me out of my device either. Furthermore, since there's no "hidden state", I can just restore a full flash dump to get back to a known-good state without possibility of something malicious getting in and hiding from me in some secured area.
I had the chance to try Modafinil (was prescribed by my psychiatrist). Same reaction as the author of this article. For a brief period, my head cleared, mind became less foggy, then I began experiencing negative reactions: headache, de-hydration, sleeplessness. Had to stop after a week.
I've noticed a kind of "hangover" effect from taking modafinil, where if I take a dose one day, I'll wake up unusually early the next day, feeling alert. But my concentration will be shot.

What happens is that I don't get enough sleep, and feel the secondary effects of that even though the fatigue is still masked by the drug. The fix is easy enough - just reminding myself to sleep more. I've found it's not difficult to get to sleep on the drug despite not feeling sleepy at all.

That said, the stuff is not a superpower pill. It affects different people differently, it affects you differently on different days, it can make you fixate on random tasks (like the author mentions) and if you're anxious about something, modafinil will make you spin and spin about it.

Works great for housecleaning, though.
