The methodology you linked to might as well be called "how to lie with numbers".

The methodology's way to assign numeric values to things doesn't relate to intrinsic things about the objects under study, but rather, is a numeric score reflecting the subjective opinion of the reviewer.

That something uses numbers doesn't make it objective, and this is a prime example.

The CrossValidated site on Stack Exchange, which is devoted to statistics and machine learning, had a question on this with some solid answers: http://stats.stackexchange.com/q/25672/5836

My take is that I'd really like Julia to take off (I would really like to be less penalized for writing loops), but libraries, and especially libraries that allow people to use it as an analysis language (rather than for writing their own bespoke stuff) is essential.

Another strategy that I've often used is to just fix a few bugs that seem to be in the vicinity of the area you want to familiarize with. Heck, I even do this on my own codebases that I haven't touched in a while.

I find it helps focus the mind, provides a clear definition of success and forces you to think about a specific area of the code without requiring too much context.

Amount of money going to healthcare is actually NOT relevant to this discussion - all the countries are spending less on healthcare than USA, none of those health advantages are caused by being able to afford healthcare because of some or other reason reason.

The call for health reforms isn't "give medicine more money", but "fix the system so that you stop getting shit priced as gold".

> This kind of result, of which there have been many, is pretty of the reason why I believe the computing power needed to rival human intelligence is vastly underestimated. And why singularity predictions are fundamentally overoptimistic.

I think you should look at the numbers some more before issuing confident proclamations like that: the brain has something like 80 billion neurons. The famous gut has more like 0.1 billion neurons, the heart has more like 0.0004 billion neurons, and one's skin isn't going to contribute that much. The number of neurons outside the brain is much much less than the uncertainty in current estimates of how many neurons are in the brain - they're just not an issue. If one can compute something approaching the brain, then one can certainly handle the rest with a spare 1% of capacity or so.
That may be true and I'm glad that (at least some of us) in the US we strive to make driving accessible to everyone, lower their cost of living, and allowing them to take that money and feed their kids - all by allowing personal responsibility. Not wasting their time and money by fining them when they very well might not need the windshield wiper at that very moment.

Do you have any numbers to suggest the cost is worth the benefit - or that there is any benefit what-so-ever?

I'm not sure that Rackspace lost their mojo so much as the market shifted away from owning/renting servers.

The low end market is more interesting at Digital Ocean or Linode, and the massive scale stuff feels like Amazon still owns that, so I'm not really sure where Rackspace is fantastic.

If service is what makes Rackspace best in the world, then they need to play that card as hard as they can instead of chasing "markets" like the "open cloud". Chasing markets sort of killed Sun and it could easily kill Rackspace.
SQLite is the Rails default, in fact.

In October 2013, NewRelic reported that 53% of their customers are using PostgreSQL: http://blog.newrelic.com/2013/10/10/infographic-state-stack-...

In July 2014, Planet Argon's Rails survey showed a surge in preference for PostgreSQL since 2012: http://rails-hosting.com/Results/2014/index.html#Database

Neither captures the distribution of usage from small- to large-scale apps, but it does look like the community has already moved both in mindshare and number of production deployments. I'd wager that Heroku's PostgreSQL default is responsible for much of that.

Yep.

But you'd need absurd reliability. Say you have something that condenses 1000 years of computation into a minute. That's ~500 million / 1 time compression.

What are the chances that if you ran 500 million copies of the machine with no time compression for a minute none of them would malfunction? Relatively small, right? Well, the single machine with time compression would end up doing effectively the same thing - the chance that it gets the right answer is probably much smaller than the chance that it goes up in a puff of smoke because the power supply freakishly died or something.

In order to do practical computation with such a system you'd need absurdly reliable computers, in absurdly safe environments. If you have a time compression ratio of 1 billion to 1, well, how many 1-in-a-billion things are there to go wrong? Better hope you're not near a faultline...

On the Last Kingmaker
I'm surprised I didn't see something similar to what I do: the deep-dive.

I start with a relatively high level interface point, such as an important function in a public API. Such functions and methods tend to accomplish easily understandable things. And by "important" I mean something that is fundamental to what the system accomplishes.

Then you dive.

Your goal is to have a decent understanding of how this fundamental thing is accomplished. You start at the public facing function, then find the actual implementation of that function, and start reading code. If things make sense, you keep going. If you can't make sense of it, then you will probably need to start diving into related APIs and - most importantly - data structures.

This process will tend to have a point where you have dozens of files open, which have non-trivial relationships with each other, and they are a variety of interfaces and data structures. That's okay. You're just trying to get a feel for all of it; you're not necessarily going for total, complete understanding.

What you're going for is that Aha! moment where you can feel confident in saying, "Oh, that's how it's done." This will tend to happen once you find those fundamental data structures, and have finally pieced together some understanding of how they all fit together. Once you've had the Aha! moment, you can start to trace the results back out, to make sure that is how the thing is accomplished, or what is returned. I do this with all large codebases I encounter that I want to understand. It's quite fun to do this with the Linux source code.

My philosophy is that "It's all just code", which means that with enough patience, it's all understandable. Sometimes a good strategy is to just start diving into it.

I think that the two most important strategies are to actually pair with someone and ask questions after doing some research.

Being able to do some pair programming helped me to understand a new code base, in a language I never used before bits by bits. I could ask questions and actually helped on the issue. Asking questions is important, but as stated on the post, you should try to find to answer by yourself first. I'll actually time myself for 10 minutes, and if I can't find an answer, I'll just poke the most prominent person based on a git blame of the file that is related to my question.

This is my second week working on a Ruby codebase, without any prior experience with Ruby, or Rails (I've mostly been doing Python with Django and Pyramid for the past 3 years). I managed to get quickly up to speed this way.
Seems like you'd either have lots of road owners each owning small bits of road, which puts you back in the many-to-many problem, or a small number of owners each with a lot of roads, at which point they basically become local governments.
It doesn't appear to have positional sensors (the Oculus DK2 does, with a stationary dongle to compare your relative head movements).

It is very disorienting if you only have rotational support (as if your head's at the same point in space) and not also positional (head moving forward, backward, up, down, left, right, etc.)
Avoiding intermediate sequence construction should help save a lot of memory consumption. That has been a major headache for me when processing large datasets in memory.

I have custom ordered a car through a dealership (not a Tesla). I'm pretty sure any dealership will do it. It's pretty standard. And they didn't charge me any more than I would have paid for something off the lot (I was able to negotiate the price the same way). However, it is definitely a pain. I had to wait months and months for the car to show up. I'm not sure if there's a good way around that, but ever since then, I've been much more inclined to just buy whatever is available that's closest to what I want, even if it's not exactly right. I do wish there were a better solution for this.
Its ridiculous to me that a company can attempt to trademark such a common geometric shape's name. How did they get away with trademarking "Square"?

Edit: Holy crap. They've filed a TON of trademarks in a ton of different categories. How have they gotten all of these? You technically can't use Square in the name of anything dealing with a computer.

Just a few of them...

BTW, someone was granted "CodeSquare" trademark before those. Also FourSquare was before those and covers much of the same legal wording. I doubt they have a strong case against you, but IANAL. The fact that you use the word "Cash" and they have multiple trademarks in the financial and computer payment space may hurt your case though.

It gets more ridiculous... CodeSquare was granted a trademark in the Goods and Services IC 042. US 100 101. G & S and then 2 years later, Square comes along and trademarks "Square" in the exact same Goods and Services IC 042. US 100 101. G & S. I'm not a lawyer, but it seems like there is a contradiction. At the very least, as a layman, it looks like some underhanded lawyer-ing that they are now using offensively.

Lastly, Square (Aka Square Enix, the video game company) also has the trademark "Square" and also is in Goods and Services IC 042. US 100 101. G & S. So two companies own the "Square" trademark within a single category. I have no idea how any of this actually works out in law, but the fact that there is so much complexity and ambiguity is startling to me.

I think your post might be propaganda, but I will respond to each point:

There are no guarantees that p2p traffic will be local.

A fair point, but trivially discounted because a single download can be propagated to everyone in a city. So when a new episode of Game of Thrones comes out, the first person to get it forwards it to everyone else in the swarm and the download gets exponentially faster with each peer. Bittorrent could easily (and probably is in some implementations) tuned to favor low latency, which would start with the nearest peers. Sure a CDN accomplishes the same thing, but it’s a larger sunk cost than using a few spare megabytes on people’s hard drives.

The connection from your home to the ISP is anything but a one-time cost.

In fact the last mile to your home is the most expensive part of your Internet connection.

This has been used as an excuse to slow the rollout of broadband for a long time. I remember when they installed the new orange fiber optic cables along the freeway where I live back in the 90s. It must have been a monumental task. And they are a permanent choke point, with the internet growing year after year, so the fee to use those lines can really only go up until more are laid. They are the reason that some ISPs limit traffic to 200 GB per month, not the load on the router for your last mile connection.

And yes, the sunk cost of the last mile connection is also expensive, but it’s amortized by future subscribers getting connected. But at some point, the rate of new subscribers will fall to the point where even that is negligible. I think we passed that point sometime in the late 2000s, about the time that my mom got broadband in her town of 15,000.

The cost of maintaining a substation and routers for hundreds or thousands of subscribers against their monthly subscription fees of $50-100 per month doesn’t pass the sniff test. Most of the costs are going to be in tech support and installation, and ISPs are notorious for taking too long to make this stuff plug n play so I don’t have any sympathy for them there.

ISPs are punting now, because it’s cheaper than making the last push to get everyone connected at the 100 Mb speeds the cable lines are capable of. They don’t want to lay new backbone, and I can’t blame them there. But the internet finds a way, and if it weren’t for the legal shenanigans of companies like HBO shutting off people’s internet, protocols like Bittorrent would have become a mainstream layer below HTTP years ago. So why would laws like the DMCA exist? To spawn the CDN industry and pour billions of dollars into building data centers that are largely unnecessary, by giving companies the legal leverage they need to pitch it.
Am I the only one reading this thinking "as written by someone who seldom dives into foreign code bases".

After a few months you'll be familiar with it?

Wow, I'm lucky to get 8 hours on a new code base before I have to ship a bugfix. Months?? O_o luxury. Sip your pina colada as you write your immediately out dated documentation. Great advice.

No, that code base was probably written by several people some of whom knew what they were doing, some of whom were just 'getting the job done' and some of whom were idiots.

Probably, the only useful suggestion in that list is code reviews. Hack a fix in, get someone who seems clued up to review and suggest a better way.

Look for logging, thats the first thing I do; you're probably not the first person to be given this code to work with, and if you're lucky the last folk(s) made some debugging tools. If not, be a pro and leave some good ones behind when you go.

...not documentation.

> There were cases here (Germany) where people had to leave their flat for one with higher rent, because the old flat was too big (welfare recipients being entitled only to so much space). But that was the government forcing them to move, not the landlords.

I know personally of a family in a similar situation in Poland. A single mother living with with three children; the moment the eldest will leave house to live on his own, the family will have to sell the flat and move to a smaller one, because with one less person living there, the flat will be considered a little too big and suddenly, all benefits related to it will evaporate.

> Not sure if the other thing would happen, landlords throwing out tenants when they don't receive welfare anymore. There are laws to protect tenants once they are in the house, too.

It doesn't necessarily have to be throwing out, it might just be "renegotiating the contract". Also the person who just switched from welfare to a job might not have a very stable income at the beginning. Unfortunately, welfare trap is a real thing.
They're not bypassing security.

I feel you're dead-on about domain-specific knowledge.

An effect of hyper-capital (not a problem with moderate capitalism) is that everyone gets hyper-specialized. No one experiences the Veteran's Administration until... they're in it with brain damage and can't write code for it.

But I would bet that any who regularly reads this website could hang out in the V.A. as an intern for 30 days and add at least $100,000 worth of annual value.

Even if it was just improving paperwork - machine learning for diagnoses - delivering education - encouraging exercise.

These problems are unexotic at first glance, b/c our society's values are so crazily skewed.

> Articles like this one paint the situation as a moral imperative, but its actually an opportunity.

I guess the author failed in this regard, b/c I read it as trying to show how it's an opportunity, although the article itself lacked your insight about domain-specific knowledge.
As noted in the announcement, all four of the new draft chapters have been extensively revised, and the last on ("Log in, log out") has been almost completely rewritten. The final four chapters (9–12) are nearly done and just need to be polished up for release. I hope to ship them some time next week.

I imagine it varies depending on the person, and maybe the brand. Some people will want to test drive the exact car they're going to buy, while others will be happy trying out the model and trusting that their unit will be the same. When I bought a new car last year, I appreciated being able to test drive the exact car I bought, although it definitely wasn't necessary. In any case, I don't think it's a big problem, just the only one I can see that would potentially remain with a test-drive-then-order-online approach.
I got to look at the API docs during the first beta. I'm sure things have changed and more features have been added so take my analysis with a grain of salt.

The HealthKit API is basically just a shared database with specific functions and structures used for measuring fitness units (e.g. time, distance, steps, heart rate, blood pressures, etc). There's a permissions model for granting read/write access to the various counters. It can also track some vitals (height, weight) and emergency contact information. And that's pretty much it.

I don't think HealthKit is really designed to do more than facilitate the storage and sharing of personal fitness data. It should have been named FitnessKit.
