The basic model that Optimizely uses is a Z-Test approximation of a binomial distribution. To run a proper experiment with that model, you should be calculating the sample size ahead of time, and then run it. Each visitor should be independent, and not affected by things like the day of the week, or the time of it. The end result tells you if the distributions are different, but not as much as one would think about the size of the differences. It also can't be 100. The normal distribution has an infinite range, so a finite limit can never capture 100% of it.

Optimizely is in a rough spot. People don't like having to think through experimental design, and they are really, really bad at reasoning about p-values. To try to fix the people part, they came out with the sequential stopping rule stuff (their "stats engine), but they never really published much justifying it. The other alternative would be to move the experiments into a Bayesian framework, but that has a lot of it's own problems. When they acquired Synference, that was one of the likely directions to take (along with offering bandits), but that didn't work out and those guys have since left.

I think the question of social class applies to my situation quite well considering that despite the fact that I'm a programmer and have a degree in computer science I honestly don't fit in well with people who would be described as middle class. Working class still seems to apply to me despite my salary and job.

Presumably anyone studying Weber and Bourdieu has also studied Marx. Anyway, Weber's influence on sociology is huge, comparable to Marx's, and Bourdieu was obviously influenced by Marx, so your comparison doesn't work on any level, really.
Sure, charity is better than non charity. Charity with ascetism is better. consumption usually created pollution, and white often is a product of exploitation. Even high income is often a product of exploitation (power imbalance effects how much money flows in your direction -- even if you are not selling that power, your employer or customer may be weilding it to your benefit )
A general issue too is that infrastructure spending seems to cost almost an order of magnitude more in the U.S. than other places.

There are many theories of this, but I can tell you that if you had to page prevailing wage to build McMansions and you could pay a market wage to build optic fiber networks and roads you would find there would be a lot more fiber and better roads and that people would find they don't need a master bathroom that is 2/3 the size of the master bedroom.

> The trendy idea that taxes in general and progressive (not in the political sense but in the technical sense) tax systems are somehow unfair is holding up important development in the U.S.

I would disagree.

The opposing trendy idea is that the eventual output of the tax systems are so filled with waste, fraud, and abuse that simply pouring more and more money, no matter the source, into politically-connected blackhole businesses contracted to perform some government sponsored task rarely if ever works and needs to much more carefully managed.

There are so many real-world examples of this (healthcare.gov comes instantly to mind, and the recent TSA app but there are many others) that I won't bother to list them.

A much greater level of transparency for all these deals would go a long way in helping fix these sensible concerns.

> software bloat almost always comes from smart, often the smartest, devs who are technically the most competent.

That's not my experience.

My experience is that software bloat comes from people who think they know what they're doing, but actually don't.

Competent programmers tend to be much more cynical about their own ability to write good code. They've been burned too many times by bad code, including their own.

The cases discussed here are not about competence or brains. They're about upgrading systems, which maintaining compatibility with existing systems. That is very, very, hard for anyone to do.

Often, this supposedly redundant data is useful in ways current society can't fathom. Millions of photos of the Mona Lisa taken over decades won't tell you much new about the Mona Lisa. But it will tell you a lot about changes in camera technology over that time.

Also, the long tail is long. There are whole cultures and subcultures that would be completely forgotten if not for archives.

At Defcon 19, Jason Scott gave a talk titled Archive Team: A Distributed Presentation of Service Attack[1]. In it, he explains why this data is important. As you rightly point out, the vast majority of it is boring and useless. It matters to no one but the author and their friends. But some of it is weird or funny, and a tiny bit of it is pure historical gold.

The early days of usenet, for example, contain tons of interesting conversations involving people who are now prominent. Thanks to these archives, we can get a better picture of these people's lives than in earlier times.

The word 'bloated' is subjective. It's 'bloated' because it was designed for something more but ended up being much less.

In other cases we also end up spaghetti code software full of hacks and bad designs because it wasn't well thought out or designed from the start.

In the end designing software that matches expectations is the biggest culprit of 'bloatware' vs 'spaghetti monster' codebases.
Yep, that's definitely my situation in life. Still working class despite the salary. It's like the areas that are suppose to be open to me seem hostile to my mere presence.

It's so weird being aware of it now after all these years.

"
And that's the type of reaction I would encourage. Yes you stop clicking on a lot of articles, but you're less likely to waste your time. I find that instead of going to around yelling clickbait, just ignore it, or at least make your time useful and either build something from the article or explain why it's bad so others could learn to ignore more stuff that source
Actually it doesn't buy time or freedom, usually.

In my experience, most (not all, but most) of the people who have a lots of money acquire it by working long days and having little free time. They also have little freedom because they are so tied to their job.

Again, everyone with lots of money doesn't have this problem, but in my experience most of them do.

Unfortunately US is consistently ranked something like 32 or 33 out of 36 for inequality across population for countries in the OECD index. Basically Mexico, Chile, and Brazil are outliers by an order of magnitude and US trades spots among Turkey and Russia year to year, then every other country does better. It's also notable that of your examples all are better with Norway, Sweden, and Finland particularly good. Furthermore the OECD household net-adjusted disposable income does not subtract expenditures it probably should, for example not all of the medical costs. I have been averaging $13000 for one child alone over the last two years in expenditures that the formula does not consider. The year before that there was even more for my wife. In a household of five it adds up and there seems to be one outlier needing more medical care than the rest.

A few people in the comments are saying 'isn't better to just setup your own SQL server instead of RDS?' and similar. I don't want to post a reply to each, so I will say it here.

While I can totally sympathize from a programmer point of view (setting up, tweaking stuff and all is a great fun), but you need to ask yourself whether it is in the interests of business to do so. Especially if you're working in a small team with no dedicated infrastructure staff or a startup with a short runway and a lot of urgent user facing changes.

Doing something on your own (e.g. setting up your own alternative to S3, or configuring your own SQL servers), comes with a cost and it's not only the programming/initial setup time. It's also opportunity cost (instead of setting up a server, I could, for example, analyze some user data); maintenance (more things to worry about which you can outsource); skills set required to run the infrastructure (running your own SQL cluster requires more knowledge, more training than running one on RDS), etc.

So is it in the interest of the business to run your own infrastructure?

If you have thousands of servers and spending millions on it - probably, but then probably you can make an attractive deal with GCE or AWS :)

If your application needs some complex performance related stuff which is harder to do in the cloud (e.g. some custom hardware or whatever), then again, running your own infrastructure might be better.

But if you are like the majority of the companies/products (you just need infrastructure to run reliably and performance should be just good enough), using AWS and friends might make a big difference.
This is only appropriate in certain situations. There are many business situations in which it's more appropriate to run a traditional A/B test and carefully examine and understand the results before making a business decision. Always blindly accepting the results of a bandit is going to explode in your face at some point.

There is no silver bullet, no free lunch. There is no algorithm that will beat understanding your domain and carefully analyzing your data.

Pick a smaller ec2 instance, and I'll find a comparable dedicated server that yields a similar price/perf gain (true, it might be more pronounced on the high end...).

Your two side notes tell me that you're conflating dedicated and colocated hosting. I can see now why you think EC2 saves you devops if you think colocated is your only choice.

I'm talking about dedicated hosting, so, no, I don't need to worry about electricity, setup time (not as much as you mean anyways), hardware failure, network access or rackspace. This is an extremely common model.

The price that I quoted I just got quickly from Hivelocity.com (1). The price is actually $300, not $400...I'm not affiliated with them at all. They've been in business for longer than AWS has existed. I could have gotten a similar price from a thousand companies.

I'm really sorry that I implied I thought Jon held Chuck Norris's views, that's not what I meant. Maybe Norris's political views are not widely known in the UK, but I thought that the BBC's title had unfortunate connotations, like comparing a good dad to Bill Cosby. It would be better to compare Jon to Jackie Chan.

My point is just that the memes of people like Chuck Norris, Bill Cosby or Josh Dugger as role models have played themselves out, and the BBC should know that.

|JS is widely considered a pain.

I find that is widely enjoyed by the "silent majority" and decried as a pain by a very vocal subset of developers. It's a little surprising that 1 + '1' is '11', until you spend a little time and learn the rules instead of fighting them - then you start doing your work in a way that uses that to save time. It's not great for everyone, but I like it - and I know a lot of other good devs who prefer the answer '11' (when you understand the fairly simple rules) to 'OMFGNOIQUIT'. I find "Number beats bool, string beats number" for implicit coercions covers 95% of cases where it would actually matter. For the other 5%, just type it in the console.

Because I like it that way, doesn't mean you have to as well - but it also doesn't mean that because you don't like (or even most of the commenters on HN) it it is "widely considered a pain".
Famous people can make money simply off the interest that the general public has in them. However, I would encourage the author of this piece and anyone who reads it to consider this point much more broadly.

For example Ronan Farrow and Chelsea Clinton were both paid hundreds of thousands by MSNBC for essentially nothing. I think it's rather telling that people would prefer to focus on someone like Nicki Minaj getting money in clubs, but that's just me.

It isn't equally ridiculous.

38.6% of Americans state that they would vote for Donald Trump over Hilary Clinton while 49% state that they would vote for Clinton over Trump.

There are only several hundred members of the IRA today (out of 1.8 million people in Northern Ireland) and even fewer of them participate in terrorism.

And it's not a logical fallacy. The cab driver clearly didn't mean all Americans support Donald Trump. Presumably he knows there are other candidates so thats at least a few people who don't support Trump. He meant a lot of Americans do support Trump and clearly they do.

Will those guys provide you with SQL Server cluster with at least 2 servers, Setup AlwaysOn, Setup failover clustering with Quorums, Optimal Disk Partition Alignment, DTC, setup subnets, ACLS to secure your cluster and lots of MSSQL Specific stuff I don't know about and then monitor it for you. Because that's what managed service is. And most ask a lot for this because of the specialists it requires.

If you pay for RDS, Amazon does this for you, and it would already be well setup below the application level. They have guys monitoring it, and keeping it up. And they can do this cheap because of the benefits of scale across all their customers.

If you just ask for machine than yes, that's going to be cheap. But your forgetting you need databases, Application delivery controllers, firewalls, VPN appliances. All of which may require niche vender knowledge to setup, and then they would charge a lot of consultancy fee's to design a solution for you. Amazon puts this stuff behind simple API's where you don't need to know all those vender specific skills.

It's a very interesting dynamic. Humanistic psychology focuses extensively on ideas of locus of control (Rotter) and self-actualization (Maslow). The perspective has its shortcomings, but I think it manages to hit on a point that many of the others either miss or place little emphasis on. People in general tend to underestimate just how significant that can be.

For example, I've always found the argument that certain voters (commonly poor white working-class) who vote for small-government are voting against their own economic interests to be rather interesting from a psych perspective. I'm a libertarian so I don't put much faith in the idea, but I think that issue could be traced back to the concept of locus of control. Voting for larger social spending might benefit them financially, but it also means accepting the belief that control over their life is externalized.

The alternative--that control is internalized or even just the perception that it's internalized--is likely more palatable psychologically as a core self-evaluation, with a more beneficial influence on other CSEs (neuroticism, generalized self-efficacy, and self-esteem). That leads to better life satisfaction, and can contribute to later economic success according to the research.

Reality is a lot more nuanced than that, but perception is absolutely fundamental in terms of how it can affect personality.
You could go further regarding lawyers: they're a government jobs program. On balance a beneficial one, but a government jobs program nonetheless. If there were no government there would still be doctors and programmers (albeit probably fewer), but there wouldn't be any lawyers.

Finally, the fact that you need the console to even understand the meaning of a code fragment is a perfect example of language failure.
