greenshackle··on Google Takes on Uber with New Ride-Share Service
Maybe what they meant is that without a wage floor people working for extra cash could take the job for below-living wage rate, outcompeting people who are looking to support themselves fully with the job.

(I don't endorse that point of view, just trying to make sense of their claim.)

greenshackle··on Millennial men with different incomes
Yeah, that looks a lot more like typical millenials.
greenshackle··on Millennial men with different incomes
Granted, but it's still a decent margin above the median millenial at $33k/yr. I would have liked to see at least one closer to the median.
greenshackle··on Stepping Backwards from AngularJS to JQuery – An Experiment
It was 5-10 pages. Static content. Yeah, even if they had 10k concurrent users node.js would have been the wrong technology.

greenshackle··on Millennial men with different incomes
3 'more or less' typical millenials? 3 CEOs and one poor guy? Really?
greenshackle··on Stepping Backwards from AngularJS to JQuery – An Experiment
My friend was brought in by a client after the previous contractor had spent 300+ hours coding a simple organizational website - here is who we are, here is our phone number - using node.js. I doubt the website will ever see more than 20 concurrent visitors.
greenshackle··on Seven Puzzles You Think You Must Not Have Heard Correctly (2006) [pdf]
From my experience as a nerd playing werewolf with non-nerds I'm afraid you're right.

Me: "Here's a plan that will defeat the werewolf in any case, even if I am the werewolf"

Them: "That sounds complicated, therefore suspicious, let's hang him"

greenshackle··on Less stress, more productivity: working fewer hours is good for you and your boss
Our team has lunch together every week or so. I wouldn't be happy with the norm of having lunch together all the time. I like to get out of the office and play stupid games on my tablet over lunch. Doing that around people is seen as antisocial so I prefer going off on my own.
greenshackle··on Less stress, more productivity: working fewer hours is good for you and your boss
I guess it makes about as much sense as paying employees per hour.
greenshackle··on Less stress, more productivity: working fewer hours is good for you and your boss
I've found that I can tell my team, sorry my brain isn't working anymore, there's no point in staying any later, and they understand.

Actually when I tried telling my manager that, he answered, why are you telling me this, I don't care what hours you work, as long as you get the job done.

greenshackle··on Olympic medals per capita
Definitely. A similar example: at one point studies started coming out that showed the best performing schools were small. Cue a lot of noise on how small schools are better, if you want your kids to be successful, send them to a small school, etc. I think these findings even showed up in government reports/recommendations.

Problem is, the worst performing schools were also small. Almost all of the effect could be explained by higher variance.

Unfortunately I don't remember where where I read about this, wish I could provide sources.

EDIT: found it. It wasnt government, it was the Gates foundation, who spent billions into supporting smaller schools.

greenshackle··on Optimism
I've read Learned Optimism, Seligman at no point makes the recommendation that overly optimistic people should be less optimistic. He doesn't seem too concerned with accuracy, he just says that optimism will make you happier and more productive, so you should pursue it.

He comes very close to explicitly stating that mild optimistic self-delusion is good, because it will make you happier.

He acknowledges depressive realism, that is, the finding that depressed people make more accurate judgments in certain situations, but doesn't really address it.

greenshackle··on Optimism
I agree with you that accuracy should be the goal, but Seligman doesn't. I read most of the book, he thinks that delusional optimism is good, because it will make you happier and more productive.

He's used his research to teach optimism to soldiers so that they are more effective. But perhaps it is appropriate for soldiers in the middle of a war to not feel super optimistic?

>If the premise is that the effects upon your past success are equally likely to be general or specific regardless of their sign

I don't know if that's a true premise. It's an empirical question. There's no fundamental reason why the universe should be even-handed.

I read a good portion of Learned Optimism a while back. I think it's a dangerous book to read for certain types of depressive personalities. Ironically, there's a reading of the book that reinforces pessimism.

greenshackle··on Why we throw away more than 6M tonnes of groceries every year (2015)
Rice and beans at the very least, to get all the important amino acids. You need at least some fat too.

You can survive for a long time on just rice+beans+vegetable oil - emphasis on survive - it's not optimal for health, obviously. You want to throw in at least some fish and vegetables for health.

greenshackle··on Acetaminophen use in pregnancy linked to child's behavioral problems
> They looked for a link between a child’s behavioral problems at age 7 and acetaminophen use by the mother’s partner during pregnancy

They thought about that. Doesn't look like it.

greenshackle··on Why we throw away more than 6M tonnes of groceries every year (2015)
Of course, there are so many factors to eating. I was responding narrowly to OP's claim that eating out is bad because it's expensive.
greenshackle··on Why we throw away more than 6M tonnes of groceries every year (2015)
However much you value your free time then. Which may actually be more than your regular hourly wage. Consider that most people need to be paid more to work overtime.

It also depends whether you consider cooking work or fun. Some people like doing it, others don't.

I don't make $100/hour and I do enjoy cooking, so I don't eat out that much, but I do believe for some people it makes perfect sense.

greenshackle··on Why we throw away more than 6M tonnes of groceries every year (2015)
How much time do you spend grocery shopping and cooking?

If you make 100$ per hour it doesnt take long before eating out is more economical.

greenshackle··on How contactless cards are still vulnerable to relay attack
in this attack the card reader is compromised. the attackers can make it display whatever they want it to.

Edit: For this to work the card itself would have to have it's own display. Another commenter suggested e-ink.

greenshackle··on Making Django CMS as easy to install as WordPress
Also: PHP has a JavaScript engine, V8js (http://php.net/manual/en/book.v8js.php)

So you could run a PHP VM on top of a Javascript VM in PHP.

Oh I didn't start with SICP either, I programmed very casually as a hobby for years before that
greenshackle··on Making Django CMS as easy to install as WordPress
I mean obviously there is no one-size-fits-all recommendation. It depends a lot what their goals and background are.

I started out learning PHP on a LAMP stack on an old laptop, and reading C tutorials online. Probably my best move was working through SICP.

If they were math-inclined and weren't worried about immediate employability I'd recommend SICP even though Scheme is irrelevant in industry.

But if they wanted to make money as a web dev as fast as possible, JavaScript makes sense.

greenshackle··on Making Django CMS as easy to install as WordPress
I bet someone somewhere is working on a PHP interpreter in Javascript.

Ninja edit: yep. (http://asmblah.github.io/uniter/demo/interactive.html)

greenshackle··on Making Django CMS as easy to install as WordPress
Yeah it's definitely improving. But last I checked the PHP internals team was very reluctant to change anything, even plain-crazy stuff, to maintain backward compatibility. In PHP, if a bug sticks around long enough, it becomes a feature.

I'm not a purist, if you're making money coding PHP more power to you. Around here there are a lot of businesses hiring people to make them Wordpress sites. But an aspiring dev asks me what language to learn I don't recommend it.

greenshackle··on Massive new study lifts the lid on top websites’ tracking secrets
Amusingly, the tactic resembles in-person haggling in China (and many other places). Salesman offers price, you walk away, they run after you offering a lower price.

Among, say, the top 10 most used languages, PHP is easily the worst.

I'm sure you can learn a lot from PHP/Wordpress, but everything has opportunity costs. You can learn better from better languages and frameworks.

My shop does Python, Java, C and PHP. I know very good programmers who happen to write PHP for a living. They are the ones sneering at PHP the hardest.

greenshackle··on Making Django CMS as easy to install as WordPress
PHP/Wordpress are ok if you're willing to cut corners.

I'm not being sarcastic, everything is a tradeoff, usually you have to cut corners somewhere.
