Heh. Whatever nifty location rewriting javascript you're using makes it impossible for me to browse your site - eg. http://www.nutrivise.com/#terms/ just points to your homepage. Also: the 'terms of use' on that page are bogus. "The most

Here, go and have a read of this article: http://skepticalscience.com/how-do-climate-models-work.html - they talk in great detail about how the models work, starting with one equation. Also look at this image further down the page: http:

It's really not that hard to work out. That you don't know what "collapse" means in the context of an ecosystem is not the fault of the paper. It's like arguing that a CS paper doesn't define what "compiler" means; there is a basic level of

>You thought that V=IR completely describes a physical resistor, when it does not. V=IR is a mathematical model of a resistor, useful under most circumstances except pathological ones. Can the model be improved? In most cases yes, but t

I'm just paraphrasing the paper. Everything that I said was in there, if you cared to look.

Those formulas are models. They describe the world and can predict it's behaviour, but can also break down under certain conditions. For example, what happens when I put 240V across a regular 20Ohm resistor? According to V=IR you get 12A ru

If what you are saying is true, then every scientific and mathematical formula would be worthless, since after all, you just get out of it what you put into it. e=mc^2? f=ma? v=ir? Yep, no bearing on the real world or any predictive power w

I prefered the original, less designed version - perhaps because it's more "programmer-ish" than the current one: http://web.archive.org/web/20110710194634/http://programming... but I can understand why it got changed :)

Oh for fuck's sake, just read the paper: BOX 1: Past planetary-scale critical transitions and state shifts Last glacial–interglacial transition18,24. The critical transition was a rapid warm–cold–warm fluctuation in climate between

They seem to be talking specifically about biospheric interactions, so it'll likely be some sort of domino effect, something like: Frog A goes extinct, frog A just happens to eat beetle B. Without (as much) predation pressure, beetle B goes

Just the first few pages seems to contradict you pretty strongly. The gist as far as I can tell is that complex systems behave in specific ways when changing from one state to another (eg. "an increase in variance in ... fluctuations"), and

I think you're confused about how models work in a scientific sense. They can be used for prediction, and if they couldn't they wouldn't have any value at all. Of course they sometimes don't line up with the real world; why do you think the

On a slightly related note, ESR is the mascot for my new static blog generating tool: https://bitbucket.org/anthonyb/shithead ;)

So you're disgusted / "surprised and disappointed" at the reaction to the CRU emails, and yet you still trust other people to filter your news for you? This is why you need to inform yourself about what's going on in the world. At least loo

Not true, or rather, not completely true. It depends on whether you're talking from the point of view of the employer or the employee. If I'm employing someone, a competitor can't easily employ them at the same time (sort-of excludable, up

Well, when I see code like that, I see lots of moving parts, all with their own weird API, interacting in odd ways. You just have to know that thing X takes a string, an object and a callback function, and there are twenty thing Xs, not fiv

I wouldn't, and I'm sure you wouldn't... but there are people who do. Case in point: OpenERP. Serious business software doing serious business things, so of course they can't use any of those other toy ORMs, they have to spend 5000 line

You misread him. He's saying that it's unfair to compare alembic, written solely by him, to something built into Django and debugged by lots of people. Which is fair enough IMO, but it's not really convincing me that Flask is a better way t

Also this is Python, so you can poke the internals however you like :)

I'm not "trolling", I just disagree with you. And yes, I know you wrote it. You wrote SQLAlchemy too.

Whoops. Mind the sarchasm there ;)

Er, that looks pretty hideous to me. I guess the idea is that Pyramid exposes a lot of the internals so that you can tweak it, but what's going on in that code is completely lost in the noise. From all of the hits that I can see on Stack Ov

The point though, is that people bang on about lightweight frameworks and composability, but what's the first thing they do? Start reimplementing^Wrecomposing Django on top of their lightweight framework.

by anthonyb 14y ago
Amen. I've seen quite a few projects that start out by rerolling the ORM, routing and templating, then grind to a halt under the weight of all the bugs before getting any significant features out the door.

But now you have an auth system that's tightly coupled to SQLAlchemy. How is that different from the regular system, other than you're using SQLAlchemy rather than Django's ORM? I'm also finding it hard to think of a use case where you need

It's from Flask's recipe section: http://flask.pocoo.org/docs/patterns/sqlite3/#initial-schema... edit: not if you're using sqlite, since alembic doesn't seem to try too hard supporting it.

Django's auth system is not that hard to hack on if you need to - in most cases you just need to write a custom backend and implement a few methods on it. It's certainly comparable to writing your own, or downloading something and integrati

Heh. Who needs python manage.py syncdb when you can write a function: from contextlib import closing def init_db(): with closing(connect_db()) as db: with app.open_resource('schema.sql') as f: db.c
