I hate to be so negative. Elon is a really bright guy and electric cars are fantastic; a real advancement away from fossil fuels. We need more of that!

But we don't need hyperloop. We need decent subways, lightrail, buses and trams. And decently fast (200km/h) intercity trains. We don't lack the technology or the engineering, we lack the political will. Pissing away billions on more techno fantasy is just a distraction while the number of cars and parking lots and freeways just keeps on growing, accreting ever more, little by little, like it has for the past 60 years in the US. The layout of and density of US cities is already profoundly inefficient due to streets, parking lots, and freeways.

A lot of comments here seem to be betting big on self-driving cars, like somehow magic chariots will appear from the sky and whisk us away to fairy land where we never have to look at a stranger or sit in a seat next to someone we don't know, or god, touch a railing! And they'll just as easily disappear into the ether where they require neither maintenance nor upkeep, storage, or cleaning. Apparently these self-driving cars will also run on magic engines that are somehow going to be more efficient than electric light rail or subway, or god forbid, a bike.

> First, there's no reason to only associate "Python" with "the language", it is an environment, ecosystem, etc. It's not interesting to narrowly focus on the efficiency of the interpreter.

Sure, but that's how people construe the post, which I think the author knows too.

The post could have been accurately titled "Python has certain libraries that are fast enough for HPSC", but that wouldn't have generated nearly as much interest as "Why I still use Python for HPSC".

People want to see others say good things about their favourite language, which in this case is Python.

I knew where the article was going (with the libraries), but still wanted to read it because even I wanted to see someone compliment Python itself, because it used to be my "primary language".

Python is a good language, but to the extent you're not using those highly optimized "C-libraries", it just doesn't perform well, and it's not suited for concurrency. That's a part of why I switched to Clojure.

I don't know what it's like where you live, but where I live, having your own office is an exceptional privilege. Not something most companies could afford for a free lance copy writer. My boss doesn't have his own office, neither does the customer I work for.

In my experience, at both large and small companies, the only people who have had their own offices were either the CEO or people whose work has them talking on the phone much of the day, so they would be too disruptive to the rest of the team if they were in the same room.

Jobs' personal vendetta can easily be interpreted as public theatrics for business reasons. Making a business decision because you are personally getting sued is completely different.

Let me frame it this way. Let's say I was working there and thought I was getting underpaid. I started interviewing, found a job paying 65k, and was about to take it. There's some grand announcement about how everyone will get 70k and I decide, great, I'll stay. Had I been provided with what looks to be the real reason behind the raise, I may have elected to jump ship for less money.
Which doesn't mean, that there are no adaption, like this one: http://www.nationaltheater-weimar.de/de/index/spielplan/stue...

Spot on. We see this a lot in coding activities. Many tasks are usually more complicated than for example "import this file into database, use the imported data to produce the histogram" ... there's bound to be plenty of "collateral" shyte en route. Non-programmers don't usually understand this.

So how to overcome this?

There's no other way than to cognitively "bring to front" the end goal every time you hit a task hurdle that threatens your concentration or that lets you succumb to distraction. But it takes practice to learn that you are in the process of beginning the "shirk move" ... watch out for this. Can you blame yourself when all you've done your whole life subconsciously toggle to other tasks when the going gets tough. Blame evolution for this.

So two things:

1. Know upfront the discrete sub-task/destination you are hoping to achieve for a given finite stretch of time, achieve it and call it the day; and

2. Kak on yourself solid! for being distracted during a tough spell ... speak it out to yourself by enunciating that you are being distracted, mofo. If someone else is doing the disturbing, find a quiet place next time. (Working with kids in the house can be painful).

That's why I am here!
> Numpy does 90% of the work

Numpy and scipy have been the core of a huge amount of my optimisations. The first question I try and ask is

"Could this be solved with matrix multiplications and summing?"

Often the answer is "yes" and allows you to group a huge amount of calculations all together, and use the heavily optimised code available numpy/scipy.

I recently swapped out something that was running at about 100 rows calculated/second to about half a million in about 0.2s.

Is phptherightway up to date?

I only ask as scanning it I see that it recommends IIS7 for production PHP on windows servers. Which I believe you could only get using an unpatched windows 2008 server?
That's not an argument. Could you explain why you disagree?

It seems that in the absence of a warning, there is no informed consent; asking for a warning allows for freedom of association.

If the OP had said "being open to guilt etc is an integral part of our university; as such, anyone refusing to go to this talk will be expelled. However, we will tell people in advance, so they can choose not to go, and then leave." I would support him. To specifically say "I'm not telling people about what will happen" means you don't want people to know in advance. How is that not deceptive?

As I noted above, the argument that the student chose a Christian college and therefore should know about it falls flat, because the student did not know about it. And if knowing was a good thing, then so would a trigger warning on the talk; it's literally accomplishing the task of making sure people know.

This is true, but we're talking SF & LA here, metropolitan areas. Blaricum is better compared to something like the Hamptons. There is no public transport because there's space to park cars, so public transportation is not necessary and it's impractical since the population is spread out.

The Apollobuurt in Amsterdam is also full of rich people and yet there's a lot of public transportation. The people living there are not against public transportation though.
"My experience with hosting PHP apps has historicity been one of fending off security issues"

Unfortunately PHP seems to have this reputation. It's not so much the language that is the problem but the people using it. PHP typically had such a low bar to entry that literally anyone could pick it up and do anything and everything with it. And quite frankly there were (and still are) a lot of beginner tutorials out there encouraging people to do very stupid insecure stuff. It now seems to be an image that stuck.

If you take a look at the OWASP Top 10, and any big data breaches recently, they are all caused by human error. SQL injection being the major culprit.

Best SEO Automation Software
> Depending on the industry, ROI is anywhere from 5,000 to 77,000 percent.

That is clearly not true. If that sort of ROI existed in anywhere near the general case, a lot more people and companies would spend a lot more money on it, and they don't. Perhaps there exists lobbying opportunities with these kinds of ROIs, but they are limited, and there definitely isn't a 5,000% floor on it.

https://www.washingtonpost.com/news/the-fix/wp/2015/05/04/am...

I think the problem with the zerohedge article (and the report it summarises) is that, first, they seem to assume that all corporate welfare benefits the businesses doing the lobbying locally (not to businesses in general, which is probably more the case -- Ford lobbying against foreign competition will help Chevrolet equally, regardless of how much either firm spends on lobbying), and second, that corporate welfare only exists because of lobbying: Politicians still need to get elected, and creating industry, jobs and high-profile ribbon-cutting opportunities in their districts (regardless of whether businesses lobby them for it or not) is likely to remain a popular tactic in the absence of lobbying.

Then don't be. There is room for one more transportation system. Money is not a single pot which gets distributed to a number of things. It's a fallacy to think that if hyperloop didn't happen more money would go to other transportation systems.
I imagine most who were changed by Snowden leaks are not necessarily trying to be vocal about it. Instead I figure they're just doing something about it. These are the people who, even if they were part of the "I already knew what was happening" bunch, probably wouldn't have done anything about their beliefs since they were only that. Hunches without enough evidence to warrant digging too deeply about, and certainly not enough concrete data to warrant dedicating one's life to.

It's a far different thing to call out your government and demand something when there's no concrete evidence to support your claims in the first place. Now governments must take citizen demands seriously, and people can now pursue these things without fear they're just spinning their wheels, because we've seen real evidence.

It's these kind of people, the ones who realize it means nothing to talk about something unless you're actually going to do something about it, who I'm talking about. My belief is leaks like this have the power to change enough people to make a real difference in the future of civilization on Earth.

And keep in mind. I didn't mention in my original comment, but Snowden leaks are something that as far as I'm concerned could warrant being required reading in undergraduate history textbooks (core curriculum). I think it was the kind of historical event that will continue to affect Earth's inhabitants centuries after we're all gone.

I may be wrong, but I would assume most teams/individuals who made the decision to implement HHVM did so to use Hack and all of its features.
Like others have mentioned, I'm very interested in how the author arrived at the ratio of '3'. At the very least this ratio doesn't take into account how capital intensive a company is, since fixed costs seem to be what's left (my understanding could be wrong here depending on which definition of 'margin' is being implied here).

Wouldn't this imply that a company with a lower ratio that is not very capital intensive would have a higher "corrected ratio" than a company which is much more capital intensive (or even simply has a higher cost of capital)?
GTD.

I can't understand why GTD is not anymore trendy (at least in HN) once it is the most efficient system I ever used. Since I implemented it, my life changed. If you ever get curious about GTD, besides reading the original book (Get Things Done by David Allen) you can have a look at my implementation (on my github), it might be a good starting point.
Thats interesting, there's been many times I've stumbled on a page "organically" and wished there were reddit or HN comments I could read about it. I would use an extension that found them for me.

It can, and it is, but there's only few places on Earth where it makes sense on a larger scale. They do it in China, and I suspect that a lot of old components make their way into new phones, but haven't seen any numbers yet.

Electronic components generally don't wear much, there's nothing that makes them unsuitable for use in new devices except that ordering new parts is probably cheaper thanks to economies of scale.

Come to think of it, maybe it could be changed? Recycling electronic components is mostly about melting the elements off the PCB and then sorting them to correct bins; the latter part is what usually involves humans. With proper design and sufficient automation, maybe there could be a fully-automated recycler that takes random electronics junk as input, and gives out spools of components ready to be used by a pick&place machine?

This is ongoing in the PHP community. For those who like purity there are tons and tons of wrapper classes that hide all that stuff away.

Modern IDEs autocomplete all the functions, I'm using PHPStorm and as soon as I type 'arr' it shows me a list of all the array functions with parameters listed.

Not perfect, but if I was worried about that kind of thing I'd use Python (which I love) or RoR (which I also love).

While there are dozens of answers to your strawman, here is a simple one:

Black people are not responsible for the safety of the citizenry, black people are not defined by the need to protect and serve us, black people are in fact, just people.

Cops on the other hand are responsible for the safety of the citizenry, are given special powers due to the additional trust and responsibility we (all the other people) grant them.

The comparison is ridiculous.
PHP is the language many people love to hate; I guess some of them like the idea of being able to point the black sheep of web development, so that they can tell "maybe we have some flaws, but at least we're not one of these PHP shops".
