Try a sport!

I too hate treadmills and lifting weights -- it's just dreadfully boring. However, if you pick up a sport, you can hone your coordination skills and progress to become a better player. I find that it's much more motivating when you're competing with people. And, I feel much better knowing that I am acquiring a useful skill that can be measured against in competition.

Personally, I play competitive table tennis (very unlike garage ping pong). What's good is that you can actually do this inside, and, it's cheap to play at clubs. It's also a sport that keeps your mind sharp. I even wrote a whole article about why I think it's a great hacker sport: http://jamesyu.org/2009/01/11/why-table-tennis-is-a-great-ha...

Don't let the term "fossil fuel" confuse you. In the early days of drilling they found fossils in the oil that came up, and this led to the common hypothesis. But people don't really know the mechanism by which oil is created (possibly this is true for coal as well.) The russians have an alternative hypothesis and have some experimental results where wells that were previously depleted were refilled. So called "Fossil fuels" may be a byproduct of processes in the earths crust and may not be finite (though we could still exceed the rate at which they are produced).

The commonly accepted theory is really a hypothesis with not that much science supporting it. The alternative theory may not have any more science supporting it, either. But notice how the name and the fact that the commonly accepted theory has been commonly accepted so long that it becomes "Fact" biases people's perception of the situation.

I hear people talking about CO2 as if your "carbon footprint" is a relavent issue all the time-- it has become commonly accepted even though, in that case, the hypothesis has been disproven. (CO2's absorbtion of IR is low, and its proportion is low, and thus water vapor is the driver of greenhouse effect. Further, in the past, CO2 has been vastly higher without a runaway greenhouse effect.)

Pet peeves with these types of comments/articles:

1) They are completely anecdotal. "This worked for me, so it applies equally to all 7+ billion humans on this earth!"

2) They assume that everyone lives in the same climate and/or lives in a similar region. e.g. How are you supposed to 'connect with nature and the sun' when you live in Alaska and it's dark 6 months out of the year? How are you supposed to regularly 'connect with nature' when you live in the middle of a metropolis?

Point taken about the name calling, but it largely stems from frustration. I don't agree with you about the lack of response or citations. I've provided plenty of data and argument - skepticalscience link to plenty of papers, independent, peer-reviewed, etc. - as well as the reason why deniers are called deniers instead of skeptics. In return, what do I get? One hack paper, non-peer reviewed, easily rebutted, and a whole load of scorn and downvoting.

If you want me to stop calling people deniers, how about they engage with the question: "How do you explain the correlation between surface temperature records and satellite temperature records, both of which show an increase?" Simple, no?
I'm surprised to find someone like you who shares such a similar viewpoint as me.

Although I don't believe it is fully impossible to predict where we will be 20 years from now -- it's just an ability that's historically limited to a few people by the role they have in the process.

You are being anti-science because you don't know or understand the science, you're just giving them citations that are completely irrelevant to the question at hand. This has been my experience with global warming advocates- they believe what they believe and they have links to papers that they have never read to justify their faith.
As for the title of your question, sure, PHP/MySQL are stil practical. If the answer to your question were no, then that would mean companies like Facebook and Yahoo aren't practical.

With regard to your future decisions, you might strongly consider another language and framework, not because one is more practical than another, but because the developers behind that framework may have more of a propensity towards the context of your startup. So, for example, Ruby has a large web application community, Python has a large scientific community, and Java enterprise.

The primary contention behind PHP has largely been it's limited OO and speed, as compared to it's brethren interpreted languages. You can, creatively, do advanced things in PHP which are done in other languages, but it's not as straight forward and often clumsy or not supported. That said, PHP is simple enough that large implementations can easily modify PHP for their own use; considering how slow PHP's codebase moves, forward compatibility is far less of an issue.

All together I wouldn't base your decision on speed. Computing power is cheap now and all of them are feasible as far as speed is concerned. If you need to build something NOW, strongly considering going with what you know. If you have more time, consider writing something cliche like a multi-user blog or twitter platform with each framework -- you'll be exposed to patterns you haven't seen before and can also figure out what you like and don't like.

Bad Science (book)
If you are a software entrepreneur as opposed to an individual coder, one of the things you have to consider is how easy it is to hire someone who knows the platform or language you've selected. It's a fact that in the US and around the world, PHP developers outnumber Ruby developers by a significant margin, probably at least an order of magnitude.

In some ways, this may seem like an unfair comparison (by way of analogy, pedestrians outnumber drivers around the world as well). This doesn't address whether Ruby is "better" or not than PHP (or Smalltalk, etc.), it only has to do with what a startup engineering manager will have to contend with if an when your startup gets traction and you need to start hiring people at a particular moment in time.
Sans evidence? So, satellite data, weather station data, ice core data, coral reef data, tree ring data, ad infinitum - all independent measurements, all agreeing with each other, is not enough?

Let me put it another way - what evidence would make you change your mind and accept that global warming is happening?

Zeolots spamming random paper citations that they've never read to people whose arguments they've never read is not supporting science. It is actually, attempting to stifle science by stifling critical thinking in favor of rote repetition of The Global Warming Faith.

Since you used the word "Denialists" I already know you deny the scientific method and actually know nothing about the science of this issue. You're just repeating the Global Warming Faith (one of whose tenants is that anything that disagrees with the faith is not science) and attempting to shout down someone accurately pointing out the spam your ideology is resulting in.
It's hard to find good/great developers period and when you find them language is rarely a concern. It's easier to find PHP developers though and dispite wanting to you'll never get to staff your team with just great developers once you grow over a couple people.

Say you have a job posting and you get 100 php developers and 5 Ruby ones. Of those 5 ruby ones 3 will people people who watched the screen casts. 2 will be intermediate/senior. Of the 100 php developers 50 of them will be horrible. 40 will be junior level. 10 will be a mix of intermediate to senior.

(In my experience anyhow, my company currently uses primarily php for services and RoR for control panels so we hire for either and cross train)
Very nice, I wonder if there is a way to keep the base plate the icons sit on a consistent size? It appears to grow and shrink as I mouse over them...
You can just as easily say RoR is slower (than, say, Symfony 2.0 on PHP with an opcode cache) and harder to work with (from a system administration perspective).

Take a look down the top 100 website list, and of those sites that are web applications, more of them will be built on PHP than not. I don't think there's even a Ruby application among the top 100 sites except parts of Twitter, but I could be forgetting something.

If the planet were actually getting warmer, as CO2 goes up, over the last decade, that would go a long way towards making your theory worth listening to.

You did not provide any evidence at all. You just linked to propaganda from an advocate of your position who made assertions, sans evidence. Yet you linking to propaganda, as far as you're concerned, allows you to claim that you provided a laundry list of evidence-- yet you never even saw the evidence you claim you presented.

This is how your position is fundamentally anti-science. You don't understand the science, you haven't seen any evidence. But a link to a propagandist, proves, in your mind, that you're on the side of "Science".

By the way, the fact is, if you actually studied that data, it doesn't actually agree. Only be selectively choosing samples can you get tree ring data, ice core data, etc to agree, and only by distorting with arbitrary factors (also known as fraud) can you get weather station data and satellite data to agree.

In fact, the claim that all this data agrees with each other is itself a bit of scientific nonsense because it presumes this data were actually measuring the same thing in the same method and were actually independant.

I have actually toyed with this idea quite a few times, most recently after finishing The Alera Codex - a series of fantasy books by Jim Butcher that I highly recommend.
It's not the same as this story but I gamed Algebra II in in high school. It was last class of the day, the teacher was a track coach and most of us were in sports. Since time was short near the end of the year we all got permission to work at our own pace... As a C+ student in Algebra I quickly did the minimum on assignments in order to take more tests more often working far past in the book than we would have reached. I turned in crap of course but the total extra credit added up real good! ;) The teacher knew what I was pulling and even had to specify certain minimums, but went along with it nicely. (Other than never telling me just how high my grade finally was. Probably ~105%.)
This has been my experience developing with PHP for many years. Especially in the early years, I found more code in the comments on PHP documentation than anywhere else (in documentation, on blogs, on Q&A sites). That the PHP community has always had this ability for its millions of users to aggregate code for common issues in one place makes its documentation much more extensive than it may appear at first glance.
Interesting! I wonder if the same (or similar) rules apply to ending actual face-to-face conversations?

In northern California, it's often cool enough to require covering most of your skin. A person surfing at Linda Mar is almost certainly wearing a wetsuit and gloves. This covers almost all of the body and drastically reduces vitamin D production.

To reliably get vitamin D, take a supplement. Exercising outside is more fun than a gym, but it won't make you any healthier than doing the same thing indoors.

I'll second everything said here. "The gym doesn't count" is an utter lie. If you've led a multiple-year sedentary lifestyle, a mere 15 minutes on a treadmill in the morning will show you an immediate difference in your motivation and mental clarity.

Also, fat-asses: you don't have to kill yourself at the gym. Look up on the internet what your target heart rate should be, and stick to it. If you feel like you're going to fall over and die, you're making it too hard on yourself.

If you're just getting started, developing the habit of going regularly (at least 3x/week) is immensely more important than minutes ran, reps, or pounds lifted.

It's incredibly hard to start and stick to a routine if you're not used to it. I've only done it three times in my life, but it paid off every time. And the years in between were racked with life-altering depression and failure.
you're converting at a relatively normal rate, right around 1% (it can go up to 3% or more with this sort of product)...you need a hell of a lot more traffic. Lots of kids take O Chem, start promoting on Facebook or something. Maybe even do ppc ads on Facebook and target undergrads.

At the low of a traffic level, no amount of testing will collect enough data in a reasonable amount of time.
Big -1 on How to Win Friends by Dale Carnegie

I think Franklin Covey's 7 Habits is much better in this regard
I think that you are sincere and so I suggest you re-read the first paragraph of your response for the answer to your question. On one hand, you linked to a blog that links to "plenty of papers" and you think this is more relevant than a "one hack paper, non-peer reviewed, easily rebutted".

First of all, it is a "hack" paper, only because it disagrees with your conclusion. Secondly "peer-review" is not a barometer of science, it is a barometer of political correctness. (Trust me on this, as I've had papers peer-reviewed in much more esoteric and less politically and government-funding driven areas.) In fact, by controlling the peer review process via government fundeing ,the global warming movement attempts to discredit all science that disagrees with its agenda... and the need to do this is proof positive that science is not the foremost consideration.

As for "Easily rebutted"-- if it is so easily rebutted, please do so. Provide a rebuttal. It doesn't have to be a proof, but an argument would be sufficient. It is NOT rebutted by linking to the opinions of others. A simple rebutted is not that difficult. I can rebut the entirety of the global warming movement with a simple statement: Temperatures have been getting lower over the past decade while CO2 has gone up.

This references two easily verifiable and non-controversial facts, and rebuts the entirety of the hypothesis. so if this paper is so "easily rebutted" do so. A link to a blog post of opinion of someone you claim also links to papers is not a rebuttal. (I stopped following such links when I found that all of them referred to papers that did not make the claim that the forum poster was asserting.)

As to your last question, you haven't provided any such records. IF you would like to link to them directly, then I will have a look. (sincerely.)
You are expressing your bigotry towards me. When I disagree, I actually disagree, and it is this disagreement that you are responding to. You can't downvote a response you disagree to (or at least hacker news doesn't let me) and I don't downvote anyway.

If I disagree, I disagree by writing a counter argument. You may not like it, it may not be persuasive, but I write it.

As to whether this guy is a "scientist" or not, I don't think it is relevant as your movement commonly mischaracterizes people according to their ideological purity.

EDIT: Now I understand why you accused me of blindly downvoting. Projection.
>I am coming to believe that ideology inhibits thought.

Your comments demonstrate that quite clearly.

Livin' la vida startup in Boston
If anyone's interested, I wrote a Vic20 clone (not an emulator) in javascript http://quietcode.com/vic It's not finished (none of my stuff ever is), and to do much with it you need to open up a javascript console and drive it via its js api

Without the console, all you can do is type and move the cursor

I've mapped a number of the more important memory locations, including screen, character mapping, colours etc.

If you're game, give this a shot (in a js console)

vic20.mem.poke(7680,1)

which will put a capital A in the top left corner of the screen. Colour memory is located starting 38400, so we can change the colour of that A to red by adding

vic20.mem.poke(38400,2)

I'd like to add a basic interpreter and the rest, but I keep getting distracted by other things. Oh, and the black strip along the bottom of sort of a cpu usage graph.

Works well in Safari, and mostly well in FF. Chrome seems to have a problem with the cursor, and IE, well... it's a no go since it's all canvas based.

I want to echo your advice. I recently started playing a combat sport after a few years of not really exercising. I have no illusions about its likely effectiveness in a real fight (not much), but since I don't plan on getting in a real fight that doesn't matter.

It is fun and interesting compared to other forms of exercise I've tried, and it definitely helps me get my cardio up. There are a couple other benefits too: when you are paying $150 a month for the class sessions, you show up. And it's easier to keep going with an instructor there pushing you than by yourself. There's also no team depending on you to be good, so there's not the same kind of pressure to perform. For someone like me whose self-control and discipline are perhaps below average, these benefits are no small issue.

I didn't start doing this to be a better worker; my primary motivation was vanity. But anecdotally, I have noticed that my productivity level has been somewhat elevated in the month since I started doing it. I'm not sure if it's the fact that I have to leave work at exactly six PM every day, giving me a solid deadline for whatever I want to accomplish in a day, or if it's the exercise itself. Heck, it could be a mix. But as far as I've seen so far I would definitely recommend it.
Ok, I give up. If you want to "engage in meaningful debate", you need to read the blog post, click through to the data and scientific papers where you disagree with what's said, and argue the details of what you disagree with.

Notice how you're completely avoiding the two questions that I've put to you. If you want me to continue to respond, or stop calling you a denier, or whatever, address either of those two questions. Here they are again:

How do you explain the correlation between surface temperature records and satellite temperature records, both of which show an increase?

What's the worst is bad code in a bad language. Having a web framework would make things much more systematic, while raw speed is going to be a hit on (compare raw PHP with CakePHP 1.1, for example).
Fry's wraps their mono-line with geegaw displays as well (usually electronics consumer geegaws, but it could be adapted to candy and trashy magazines). A cynic might wonder if they might actually want to maximize wait time, but I imagine it is, as someone points out below, a question of space limitations (carts require lots of space to navigate a rope maze). I note that the self-service stations slowly taking over the mega-grocery stores here employ a mono-line protocol. But, I find these inconvenient unless I only get a small number of items, which, of course, would require me to make more frequent trips, nulling out any possible time savings).

Grocery delivery would seem the only way out.
Out of all the arguments against AGW, the complaints by McIntyre against the Mann analysis are the only ones I've heard that seem to warrant being taken seriously. If you really can get rid of the entire 20th century warming by removing a small set of proxies, regardless of the statistical analysis, it's a serious problem.

And the response on the "skeptical science" web site, that new data has confirmed the hockey stick shape, doesn't sound convincing either. You can't both say "ok, the Mann analysis was wrong, and the field has moved on" and then say "subsequent data confirm the hockey stick" without needing to explain the remarkable coincidence that the initial incorrect study ended up getting exactly the same shape as the new "correct" data.

What I've not seen anywhere is an analysis of the extent to which projections about future warming is driven by the exact shape of the 20th century temperature record and how changing the temperature record would feed back on the GCM projections. If anyone knows of such a study, please post the reference.
