You don't need vector calculus. My demonstration of the power factor is a children's swing: if you push against your friend as they travel out you do work on them: if you make contact with your friend aas they're coming back, they do work on you.

Kids have a pretty good mechanical model of swing sets.
I still do.
Suspending disbelief for a moment, and taking this seriously ...

I take issue with the following statement:

> A stupid person is more dangerous than a bandit.

Sometimes, perhaps. However, a bandit, by his gain, can give himself more resources with which to continue his banditry. A stupid person, on the other hand, will tend to deprive himself of resources.

For example, I decide I want to be nasty. I'll drive around town and siphon gasoline out of people's cars. As a bandit, I might put this gas in my tank, thus enabling me to drive on to the next victim. I'm not a perfect bandit, since it cost me some gas to get to my victim, and so the total amount of available gasoline in the world is reduced by my actions, but I do gain somewhat. On the other hand, as a stupid person, I might simply dump the siphoned gas on the ground. And eventually, I run out of gas, making it more difficult for me to victimize others.

(Okay, I'll stop taking it seriously now.)
That's pretty expedient. The Wayback Machine hasn't even taken a snapshot of you yet. :)
Here's a link to the FCC's PDF: https://fjallfoss.fcc.gov/prod/oet/forms/blobs/retrieve.cgi?...
It's not in the same order of magnitude (and maybe off-topic), but from the leaked documents of Twitter, Google was directing much of the Twitter APIs implementation, from their tone. And twitter was in the boom stage (2009, sorry can't find a source, techcrunch iirc).

I don't have any experience in acquisitions by large companies, but from the twitter story (above) I made an idea of the tension going on. It's like you're a soldier and their the commandant during a war, most of the time you just can't say no.

edit: I meant, if you say no, you have to be prepared for the consequences.
Wow. Are you seriously complaining about that? One day someone's bitching that open source is for commies and can't make you any money and then another someone's complaining that the open source companies that do make money are TOO enterprisey!

I prefer Target, and local independent shops to Walmart. I am extremely glad, and grateful, however, that Walmart exists. It is a major driving force behind improvements in the stores I do like.The same is true of Home Depot versus Lowes (and versus any other similar store). The competition is what keeps things serving me well. Without Linux, Microsoft, et al. wouldn't have done nearly so much.
This is a real shame, because I just started using Divvyshot (first event: birth of my daughter on March 8) and I really, really liked it.

It filled a great niche. A year ago, a bunch of friends and family and I went on vacation, and we all talked about trying to set up some kind of photo sharing spot where we could see each other's photos, but it never happened. Divvyshot, though, fit that bill.

Facebook doesn't do that for me, so I've downloaded the photos and will be deleting this event. I realize that getting bought out is a positive thing for the founders, but it can be a negative thing for your users, and it certainly feels that way to me. Bit of a letdown.

All that aside: great product, and best of luck to you guys in the future.
You can't just mix and match patches automatically. Someone has to resolve merge conflicts. There is a cost to this: developer time.

Distributed version control systems are being so successful because they allow developers to more easily do what they have been doing all along anyway (take Linus' job, for example).

I don't think there is a major paradigm shift here; just a revolution in tooling. There will still always be a main line. That main line will not be "distributed", even if the way that changesets get there might be.

Most of us will only be using releases taken from the main line. Forks will carry on happening from time to time, but just like now most will work to avoid them because of the inefficiencies that result.
In other words, you want the USPS to discriminate on something other than cost of delivery.

Why should we enact your preferences instead of, say, mine?

Note that it's quite possible that spam is helping to keep first class postage prices down. (Eliminating 30% of the USPS's revenue does not eliminate 30% of their costs. FWIW, I suspect that direct mail is a greater percentage of their revenue than 30%.)

While you may willing to pay more to send USPS mail in return for getting less spam, other people probably aren't.

Which reminds me - you have gone to the very slight trouble of the first two steps listed at http://www.epa.gov/region1/communities/stop_spam.html , right?
Are you willing to say consumers aren't better off because of those open systems?

I'm willing to say that consumers are better off because Linux and Apache are used in places where they are the best tool for the job. I am not convinced that being open is inherently the best thing for anybody. How much of the web wouldn't exist if not for people just trying to make a buck? Would Y Combinator?
if you suffer from the action of a stupid person, you have participated in an interaction where both you and the other party lost. By the author's definition, you are stupid.
Would that be the fate of software? will that be a benefit, if software like Apache be closed? and only vendors with closed technology sell closed software?
I've written a (non-OSS, so no link, sorry) lib in JS that I ported to Ruby, C# and Java. The API methods in JavaScript are all lower camelCase as are the Java ones. The C# ones are all upper CamelCase and the Ruby ones are all lower snake_case (or whatever it's called).

Basically, I try to follow the conventions of whatever language I'm working in because that just makes it easier for people working in that language to incorporate your lib.

And yes, lowerCamel seems to be the default for JS.

For a JSON wire protocol it's different, because it's not a language specific API that you're exposing, it's a protocol, which is a different beast.

For text-based wire-protocols I prefer to 'ignore' case (because of ambiguity) by sticking with lowercase all the way. Names need separators and the underscore works nicely for that everywhere.

Keys I use for sending over the wire therefore follow the Ruby style.

I expected this to be 100% gimmick, but it actually works pretty well and I found the 3D effect way better than I expected and actually pretty compelling. Nobody's going to be using this feature for anything more than novelty right now, but when you think about the new 3D monitors coming out, if Google could roll out a version that instantly worked as good as this (or presumably even better) with the new 3D display hardware, then I'd use that by default all the time.

Replying to your aside: With HTML5's offline capabilities you don't really need hosting (for many kinds of apps). I need to run a server on my laptop only once so I can download little programs I write to my iPod.

With this method I don't need to pay Apple $99 or write Objective C. (OTOH I did need to learn JavaScript, but it turns out it's nowhere near as ugly as I for some reason thought it was.)

By the way, as a handy tinkerer friendly tip, the first thing I put on my iPod this way is a very simple form with a text entry for JavaScript code that gets eval()-Ed and printed. Now I can code simple things right on my iPod.

But Apple would never let me install a radio that would tune into adult shows like Howard Stern. And they'd block all Sirius XM radios because of this possibility.

And if someone created a radio that used too much battery life, I wouldn't be able to install it either.

The parent poster goes on for length operating under the assumption that no one on HN that is participating in this discussion or up-voted the news item shares the same views that Doctorow does.

I believe you have misinterpreted. The parent post does not refer to HN readers, but to the obviously ambiguous "most people". The post it was in reply to distinguishes between "Most of the world" and "we" (meaning HN readers), and I propose to you that it is the former group that was meant.

The parent poster acts as if HN readers/participants are just like rats dancing to the Pied Piper's tune, that need to be woken up.

That appears to be precisely the attitude it is rejecting, in reference to Cory's desire (as described by the parent to that post) to protest loudly something that it is said few who don't already know actually care about.

I would also point out that you yourself drew parallels to the specter of Nazism (http://news.ycombinator.com/item?id=1237826) and of unheeded warnings. Are you yourself not acting as though others need to be woken up?
> FICA taxes and medicare taxes, adding up to 15% or so, only apply to your first 100k or so of income. So if you're making 500k, you're probably paying less in taxes as a % of your income than your secretary.

Not even close. (And your numbers are wrong. FICA alone is about 15% and medicare is about 3%.)

You pay medicare on all earned income. (And, with Obamacare, you're going to be paying it on unearned income as well, if you're making $200k as a single or $250k total for married couples. Yup, married engineers are going to be hit by this.)

Back to the secretary. You paying the same rate on the same income. You stop paying FICA at $105k, but by then you're in a higher bracket for other taxes.

At $500k, your marginal rate and average rate are pretty close. Below $100k, they aren't.

No, you don't pay FICA above $105k, but you also don't get benefits from higher contributions.

Someone else pointed out how the benefits change as a function of contributions so I'll point out why SS advocates set up the system with a cap on both contributions and benefits.

If the system has uncapped contributions and benefits, it will end up paying Ross Perot $500k/year. I suspect that you're not willing to do that.

If the system has uncapped contributions and capped benefits, rich people will pay a lot more attention and work to reduce SS because that would be a huge hunk of money.

The other alternative, capped contributions and uncapped benefits is a non-starter.

That leaves us with the current system, capped contributions and benefits. SS advocates picked that because they thought that a SS system that rich people ignored was best.

Were they wrong? Do you really want rich people paying attention to SS? They will if it's taking 15% of their income.
I should have announced my Bash microframework, martin, yesterday: http://github.com/tlrobinson/wwwoosh/blob/master/martin.sh
Doctorow's "think of the children" argument is absurd. How many kids are really going to have an iPad? Their parents might have one, but does anyone think that'll be the only computer in the house? Apple doesn't make commodity devices, they don't compete in the low-end, and they rarely drop prices. If I had an 8-year-old son, do you think I'd let him take a $500 anything to school?

Children who weren't as fortunate as Doctorow to have parents who could afford an Apple ][ will likely have a cheaper, open alternative. Commodity hardware that wasn't available in the good old days. Back when you had to be either lucky enough to attend a private school with a computer lab (Gates), or have an engineer father working at Lockheed (Woz), or any number of other examples.
I agree with the fundamental philosophy behind Doctorow's argument, but good grief:

The model of interaction with the iPad is to be a "consumer," what
William Gibson memorably described as "something the size of a baby
hippo, the color of a week-old boiled potato, that lives by itself, in
the dark, in a double-wide on the outskirts of Topeka. It's covered
with eyes and it sweats constantly. The sweat runs into those eyes and
makes them sting. It has no mouth... no genitals, and can only express
its mute extremes of murderous rage and infantile desire by changing
the channels on a universal remote."

I don't know if it's possible to be more shrill.

Take a close look at the game industry for a glimpse into a slightly more probable future. The consoles, dominant as they are, did not kill PC gaming. A significant and very profitable chunk of gaming occurs on personal computers. The indie gaming scene is arguably stronger now than it ever has been. There has been an explosion of inexpensive or free or open source game development tools, engines and libraries over the years. As a result, it has never been easier or cheaper to make games and share them with others than it is right now. That's good!

On the other hand, the corporate gatekeeping to the console publishing world makes the App Store look like GitHub. That's bad!

It is far more useful to address actual problems that computing appliances might pose than it is to paint apocalyptic sci-fi scenarios where we are transformed into creatures made up mostly of eyes.

The Java applet is really bad, pleeeease find another way for users to upload their photos.

Here are some major pain points (and some suggestions):

- The reliability of Facebook Photos is pretty suspect - the AJAX picture loader will get hung up randomly, increased reliability here will make the system a lot more polished.

- The Java upload tool really, really sucks. I would even take a Flash uploader over it, and I really despise Flash. Letting the users interact directly with their file systems may not also be a great idea - can you slurp directly from a memory card or camera connected via USB? This may convince more people to use Facebook as their only stop for photo storage.

- Photo API could use some work - right now the Lightroom Facebook plugin can't seem to delete photos. This means that when I make modifications to a photo and re-publish it just creates new photos on top of the old ones. The Flickr API allows overwrites, which means that the files can be seamlessly replaced, preserving comments and other data.

- iPhoto's facial recognition stuff is really really really cool, it'd be great if Facebook shamelessly stole it :)

Before you start categorising yourself or other people, you might want to read up on the Dunning-Kruger effect,

The Dunning–Kruger effect is a cognitive bias in
which "people reach erroneous conclusions and make
unfortunate choices but their incompetence robs them
of the metacognitive ability to realize it". The
unskilled therefore suffer from illusory superiority,
rating their own ability as above average, much higher
than in actuality; by contrast the highly skilled
underrate their abilities, suffering from illusory
inferiority.

'Fork' isn't his choice of word. On github, a fork is just your version of someone else's repository.
Sure, it used to mean that, in the days of CVS.

But a github-style fork is a fully independent project in theory, it could go anywhere. It doesn't have to reintegrate. It might out-speed the main project and come to replace it. It might change emphasis and shoot off on a tangent.

It's not really the same thing as having a copy of the source and making some private changes.
Maybe you can get some help from http://timesvr.com
When there's only one repo, there's no ambiguity about the content represented by a revision number. Revnums are perfectly adequate for the many situations in which frequent coordination with a central repository is completely feasible.

Git also does not require every file and subdirectory to be modified by every merge, so based on that criterion it's no more astonishing that SVN merge tracking can work than it is that Git merge tracking can work.

SVN's merge tracking was an after-thought, and it was implemented using the general, user-visible, metadata facility (properties). So historically svn was prone to problems such as repeated merging, and today it's possible to make things complicated, and then manually edit and botch the complex merge history, and suffer.

Fundamentally, svn:mergeinfo summarizes history rather than pointing only to merge-parents. I suppose the latter is what you mean when you speak of clear-thinking primitives. I wasn't involved in the mergeinfo design, but it seems less likely the result of muddled thinking than of a design decision recognizing that the entire revision graph isn't locally available to svn users and that the summary is sufficient under reasonable restrictions on usage.

Your condemnation of svn as a "hopelessly hamstrung" "dead-end" seems derived more from your dismissal of centralized version control generally than from the particular details of svn's design or implementation. In that dismissal I think you're taking too narrow a view of the ways in which people work together.

Ask HN: got any food hacks?
I'm having trouble finding a way of consuming food that has an optimal balance of being healthy, cheap, quick, and tasty. I don't want to eat ramen (or most processed foods), but I don't want to spend an hour every day preparing, cooking, and cleaning. I was wondering if anyone had any suggestions to share (tips, recipes, whatever). I'm a single grad student, but advice for others is also appreciated.

For example, I remember an HN submission where the writer talked about paying someone who lived nearby and cooked well to drop off leftovers most evenings. Someone else talked about preparing a whole bunch of meals the first weekend of the month then freezing them (this probably requires a second fridge). From the body building community I picked up the idea to drink a lot of milk, because it's a great source of cheap good calories. I'm not necessarily looking for actions so drastic and perhaps "gimmicky", simpler ideas would work just as well ("making such-and-such is really quick and makes a bunch of leftovers that taste just as good as the first time", etc.)
You'd be surprised at how prevalent Internet usage is in places like Haiti...
The platform on which iPad apps are built—the Mac—is a great piece of technology, and is indeed revolutionary in its use in the creation of modern software and digital media. But that's not an argument for the iPad being a creative tool. It is not part of the process of utilizing its own SDK.

Until I can add features to an iPhone/iPad without shelling out for one of Apple's "real" computers, I will consider the iPad a consumption-only, and thus an unnecessary, device.
I'm curious as to how that would matter too much.
I hate that people like Gruber keep making the analogy to automobiles.

Because the car manufacturers didn't try to lock down their system and took government intervention to prevent this? But if Apple does it, it's just "progress".
