I know what you mean, and there has been wireless successful wireless startups so there is a case for it. The big issue though is bandwidth. With ubiquitous wifi hardware (thus cheap), you might be able to push 100Mbps (rough guess, I'm not sure how multi-antenna systems work for the 300 limit, I would assume 1 antenna to a person's house though). Which would be great but you're not going to get it unless you're standing next to the base station. You have to go through thousands of feet of air and then share what's left with everyone else using that AP. How many people would share an AP? Assuming 4 to a tower, easily 100? During peak times of day, I doubt you could get WiFi to deliver speeds that rival current offerings and it may be difficult to even match them (my local WiFi provider just recently broke 15Mbps for their top business tier at a much higher price than local cable).

You also need to physically install and maintain antenna's on everyone's roof (how would this work at apartments?) and hope there's no buildings in line of sight to the tower. Both of which would be highly vulnerable to weather (you put lightning suppressors on those people's antennas and ran a grounding wire to the earth right?).

TL;DR: I don't think wifi is any less of a nightmare (purely hypothesis though, I don't have experience with either in public infrastructure) but we see it more simply because initial cost of deployment is less.
Yes, it does sound like a power issue. This is pretty common on the Pi given the massive variability of USB power sources.

You don't really have any rights to your image taken in a public place.

Gets a little dicey when your image is used in a way that could be viewed as you endorsing something, like an ad or a service. For that I use a pretty blanket model release form, but it's a grey area. Unless you are rich and famous. They have their own set of rules.

Look at the Corona SDK for developing iOS and Android apps in Lua. This is fantastic tool. A friend has used this to crank out a number of book apps for iOS using this SDK and the Kwiksher add-on. One note, last time I looked this SDK wasn't using the native UI components, maybe that's changed recently.
Just like an artist only has the techniques: move pencil horizontally, move pencil vertically, move pencil toward or away from the paper. The art comes from knowing what to draw and how to combine these steps based on a vision in your head. And the real part of pure mathematics is envisioning new structures and new relations that nobody has used before, at which point the proof itself can become a detail. IT's not through lack of trying that formal computer proof systems haven't been able to touch a milli-part of modern mathematics

This is also a point brought up in the great guide: Advice to a Young Mathematician, http://press.princeton.edu/chapters/gowers/gowers_VIII_6.pdf

> We are all taught that “proof” is the central feature
of mathematics, and Euclidean geometry with its careful array of axioms and propositions has provided
the essential framework for modern thought since
the Renaissance. Mathematicians pride themselves on
absolute certainty, in comparison with the tentative
steps of natural scientists, let alone the woolly thinking
of other areas.

> It is true that, since Gödel, absolute certainty has
been undermined, and the more mundane assault of
computer proofs of interminable length has induced
some humility. Despite all this, proof retains its cardinal role in mathematics, and a serious gap in your
argument will lead to your paper being rejected.

> However, it is a mistake to identify research in mathematics with the process of producing proofs. In fact,
one could say that all the really creative aspects of
mathematical research precede the proof stage. To take
the metaphor of the “stage” further, you have to start
with the idea, develop the plot, write the dialogue, and
provide the theatrical instructions. The actual production can be viewed as the “proof”: the implementation
of an idea.

> In mathematics, ideas and concepts come ﬁrst, then
come questions and problems. At this stage the search
for solutions begins, one looks for a method or strategy. Once you have convinced yourself that the problem has been well-posed, and that you have the right
tools for the job, you then begin to think hard about
the technicalities of the proof"
The difference I describe is that it would be easy for anybody to do it. You literally download your low recoil machine gun (sold in the 50s) like you downloaded that textbook off bit torrent and press print. Then you print off an ammo reloading robot and your pretty much done.

You don't need machine shop expertise and $10k/$100k worth of equipment. The 'no guns' strategy would fall to pieces in the face of that. That's why no guns works in reducing gun ownership in the UK.
Tent handles photos as "attachments" and doesn't push them out automatically. What it pushes out is a photo post containing the URL from which the actual photo can be retrieved. So your server's bandwidth only gets consumed when someone actually views the photo. It's about the same from a bandwidth perspective as hosting a WordPress photo blog and providing an RSS feed.

Now when you get into the millions of followers, like Lady GaGa has, your complaint is a valid one for textual posts (which are pushed in full). But at that scale, privacy clearly isn't an issue, right? I don't see much use for saying "these 3 million people can see my post, but hide it from everyone else". And if the posts are public, you can use a model like PubSubHubbub's to ease load on the origin server. Tent doesn't have that kind of feature yet, but I imagine they'll cross that bridge when they come to it.

I also disagree with this reasoning:

> There's no way an individual or group is going to be able to host their own servers. The whole system just dissolves down to a single large provider serving the vast majority of people, and we're back to Facebook again.

The first sentence is, in most cases, true, just like most of us don't host our own email servers. There's a substantial economy of scale with email. But can you name me one example of a "single large provider" that monopolizes hosting an open protocol? I can't think of one. With email, we have three large providers (Gmail, Yahoo! and Hotmail together serve ~80% of US users), and we also have a number of small providers. That means you have a choice.

This was a much more thorough article than I was expecting, will have to bookmark for later.

From the OP:
> At the end of the conference, Evan Phoenix sat down with Matz and asked him various questions posed by the conference attendees. One of these questions was about the GIL and why such a substantial “two dot oh” style release didn’t try to do something more ambitious like removing the GIL and enabling multicore execution. Matz looked a bit flustered by it, and said “I’m not the threading guy”.

The fact that a lot of Ruby's development (at least MRI) is in a language totally incomprehensible to me is part of my fascination with Ruby...I remember there being some discussion awhile back about translating Matz's original Ruby documentation for historical purposes...as it is now, some of that design and thought process is probably still locked in Japanese. I'm sure he's discussed it in postings and in conferences since, but did Matz have any kind of intractable philosophical objections to threading, other than it being a ton of work involved? That is, did he or any of the MRI team think that it would take Ruby too far away from its original design goal?

Because the word "identified" comes with special significance. It's a positive identification from the police as a matter of fact, and it's an official position. It carries weight and is reportable without the risk of libel. A low-level lieutenant who heard a name and then told the media to curry favor is not identifying. He's providing a lead, which must be confirmed from another source.

Compare: We are positively identifying the suspect as John Doe, who is in custody.

With: Hey, we are looking at John Doe as the suspect.

One is identification, the other isn't. It's a legally-important word and distinction. Again, I worked in the field, and your shot at the end about my personal bias was uncalled for and marred your otherwise good parry.
Assuming 2460 kwh/ton of coal, and 36kwh per 100 miles of driving this driver burned 1.7561 tons of coal.

Assuming he drove a gas powered Honda civic instead he would have burned 375 gallons of gasoline (12000 / 32 combined MPG).

One ton of coal releases 2.86 tons of C02. One gallon of gasoline releases 19.64 pounds of C02.

Driving the electric vechile released 5.022 tons of C02.

Driving the gas civic would have released 3.68 tons of C02.

All numbers shamelessly cribbed from whatever google result seemed nice.

Simple Tip For Motivation: 'Encouragement.txt
Well, in your previous comment, you pointed out that paying high taxes is not an altruism, but just a deal/agreement with your government.

So, at some stage you might be comfortable with the conditions agreed, but you might also get to another stage of your life, when it is not comfortable anymore - thus you start seeking better deals.

There is nothing bad or evil in this.
Very cool. It would be nice to see a breakdown of where the energy he received while plugged-in at home came from. I think it's great that we are reducing our dependence on fossil fuel, but at the end of the day if the energy to power that car is being generated by dirtier or more costly ways... it doesn't really matter.
> Social media is not a public utility. Using Instagram is not a right. When you begin using these services, you enter a legally binding contact with them, defined in the Terms of Service.

I think there may be a difference in audiences here. You have the literal version of US law, which is what this article appears to be based upon, but you also have people's expectations, which is that companies should not abuse their position with respect to the data they hold.

From an American point of view, the idea that people can form any contract they like with a company presumably makes sense. From a European point of view, there are public limits on what a company can do with data. The Uk is not alone in having a data protection act that absolutely limits the use of data sell on, for example.

This of course brings up the question of which law applies, and companies are very adroit at manipulating this. But it's hardly surprising they aren't so good with public opinion.

My own view is that cloud providers should have a European style data protection act, but that's mostly because I like the law and find it to my benefit. However, even where there isn't a law, if I think my data is being abused, I'm more than happy to call a company out on it.

My counter argument to the one that says: they're a company, they can form any contract they like

is: I'm a free individual, I can protest that.
I've done a fair bit of development inside Postscript (way back when it was one of my favorite languages) and its problem in this context is that it /is/ a programming language, and one that would have to be effectively sandboxed. HTML on the other hand is purely a markup language, is extensible, can be reflowed, and is much more natural for writing documents by hand.

From Dev Bootcamp to Engineer at Hipmunk: An Interview with Phil Aquilina
Anecdotally, the years I've been in this situation I've found it extremely painful - way more painful than the years I make $40K or so.

I'm sure there's a threshold beyond which you just don't care, when you already have enough money to do everything you could possibly want, but whenever I've written a check for hundreds of thousands of dollars to the government I think "well, that probably would've paid for the college education of one of my kids" or "well, invested prudently that would've let me retire years earlier." I've also thought "huh, I'm getting exactly the same services as everybody else but paying ridiculous amounts of money for them."

Neither's a particularly good feeling.
I've got an interesting relationship with perl. My first exposure was back in the 80's when I was at Sun and perl was, to my taste, a shell scripting language with the complexity of APL and the readability of Forth. I hated it.

When I took the job at Blekko they said "We do most of our stuff in perl" and I was dubious about that.

However, now that I've been exposed to V5 for a couple of years and have probably written a few thousand lines of code in it, I find its easier to write a quick hack in than Python, and it certainly has a better 'command line' feel than Java. But it wasn't until I started coding up a quick CMS type gizmo for making HTML pages that I truly "got" the power of CPAN backing it up. There is a lot of stuff there. Folks like me who gave up on the language in the V3/V4 days as "hopelessly hacky" should re-visit it.
This is an excellent example of why comments and well documented code should be part of the licensing agreement.

The paper enumerates all of the shortcomings it has. So, what more did you need? Essentially, it can be highly influenced by where the initial means are chosen and the existence of outliers. Further, on multidimensional data you have to take care in choosing the distance formula. (There was a great blog not long ago about using K-Means to find the "palette" of an image where many of these shortcomings can be seen easily.)

That isn't to say the algorithm can not be used. It just is not bullet proof.
You're right--there's a lot more to it than just "the tax rate". You've got to consider what that tax rate is getting you. It's also reasonable to have high earners pay more in taxes than low earners--the high earners arguably benefit much more from the infrastructure in place allowing them to even earn a high income in the first place (eg, rule of law), so it is in their interests (and power) to keep that infrastructure humming. When you're rich, social darwinism seems all good and well until you've got the disenfranchised in front of your castle with torches and you can't call the police because their budgets were cut.

That said, I think france is a pretty good example of a place I'd never want to live if I planned on producing anything of value. I don't think it's a coincidence that france is not exactly a hub for startups. Australian and French economic policies are quite different.

So regardless, it's not an apples to apples comparison and not all tax spending is created equal. Personally, I think the French have really bad economic policies if they're interested in anything more than stagnation and taxation is partly to blame.
the only area where I can see this as being a problem is with Excel. For the others, use a web-authoring tool. Why create a MB document in Word, to attach to a SharePoint page, then send a link to every pointing out the new document? Excel has some specialized math functions (and data presentation abilities) that are beyond LO/OO. But I think it's such a small percentage of people that need that functionality, you could replace MSO w/ LO/OO and most everyone would say 'meh' and go back to work.

> To reduce the likelihood of a totalitarian state.

That is my beef with that Amendment -- it doesn't apply anymore. It will not make a difference. One can say we have been slowly sliding towards totalitarianism (plutarchy maybe) and the fact that some people in Michigan are gathering regularly, putting face paint on and then shooting beer cans from AK-47s doesn't make a difference at all.

As you agreed Founding Fathers could not have predicted massive surveillance that would make Gestapo proud, satellites, tanks, nuclear weapons, etc. So in their time 100 militia people with rifles could take 100 government solders with rifles and it would be a nice match.

> Of course not. That's why we have courts.

Alright I agree only if the courts would correctly reinterpret the amendment and let me have a couple of nuclear weapons, some drones with weapons, tanks, and fighter planes. Because what is really meant by "arms" these day. But I can't even buy a fully automated machine gun.

To me personally, most times guns are used in this country against someone by a civilian they are used either by drunk family members against each other or by criminals.

> The authors of the Fourth Amendment probably couldn't have imagined laser microphones, but the courts have held that using one (or anything else high-tech) to eavesdrop on conversations you have in a private place is just like a search and requires a warrant.

But their hands are tied. So they can reinterpret the Second Amendment (which I have concluded they haven't as citizens don't get access to matching arms as the government does) but only up to a point. Like it can't reinterpret it so take away the guns. At some point if it is written it is followed blindly like some magic book from the sky.

The original article was trying to use the "reinterpretation loophole". I don't agree with using loopholes. But I agree with the intent (remove the weapons) by do it by fixing the Amendment. If Amendments can't be passed anymore (practically) then there is something broken about this country.

The way it is now, the Amendment does more harm than good.

"Don't talk about your success because you'll give away your secrets and increase competition, lower the barrier for competitors."

This is the truth. I know I've gotten ideas from posters like the OP talking about how profitable an app is. If I have a bigger team or more resources, I could take away your customers pretty quickly.

"Jealously guarded secrets retard the growth of industries"

Really? Rather than everyone using the exact same idea/code base and branching off from it, we have completely different products. It helps the growth of industries and ends up being better for the consumer (more choices, etc).

"They want Plants vs. Zombies not a clone. It's music, it's art, and guarding your secrets about how you make your art is unhealthy."

Don't blame anyone when you can't make any money because you gave all of your best stuff away for free.

Making money from the app store (or any startup) is hard enough as it is.

Do you really want to take a chance and give away any competitive advantage that you may have had?
