> What I tend to see in this demo is how to make a doorknob unintuitive, how to make music player functionality undiscoverable, how to accidentally lock yourself out, how to frustrate a user whose mental model of the sensor is incorrect.

The same could be said about touch technology. And usually is, for the first week someone uses it the first time. My friend, a good sysadmin, was often asking me how am I able to figure out how those Android interfaces work, then the other day he got an iPhone, and he was complaining and complaining... until he stopped, after a week or so.

I think discoverability is a bit overrated. Lots of things around us are bad at it, and people learn by showing to each other how to use the stuff. And as long as stuff behaves predictable, we can quickly grasp the patterns, no matter how nonintuitive or counterintuitive they are.

Or maybe I'm wrong, given how often I have to show people how to do things like setting the timer on the microwave or reconfiguring a VCR or whatever, given that they own it for like half a year and for me it's a first time I see a particular model (or sometimes even entire class of devices) and I don't have (nor have a need for) a manual. I don't know, maybe some people have troubles building mental models based on reasonable expectations about what a machine can do (I observed it strongly in one case). Anyway, I'm surprised by this phenomena, given that I once had to show to a good sysadmin how to set a clock on his microwave, 'cause he couldn't figure it out (and long he tried).
Then, of course, there's people like you, to whom profit is so suspect that you'll take your chances with the same government that brought you DCMA, PATRIOT, came within a hair-width of passing SOPA and PIPA, the war on drugs, warrantless wiretaps etc.

It's not that government can't do good things, it's that when they screw up, they do it real bad, and fixing it, if at all possible, takes decades.

If the government can pass a sensible internet privacy and security law, then I'm all for it. It's just that the potential of times probability of a screw up that makes everything worse for everyone is very high.
I think you just said his average article is average, and his best articles are great.

The title of the original article is "Invisible WiFi Signals Caught on Camera." I thought "Invisible" was too Ripley's-Believe-It-Or-Not-sounding so I removed it while trying to keep as much of the original title as possible intact. Probably a better title would have been "WiFi Signal Strength Caught on Camera" or the one you proposed, but, whats done is done.

Since then i made clear that i don't touch those anymore, someone else can waste their time. Especially when you spent more on fixing some script then it would take you to rewrite it in python..

A bit more from Gruber (after some insights from marco from Instapaper). Gruber: " They never seemed to treat software engineering and design as a primary function of the publication. They were competing as much against Flipboard as they were The New York Times, but didn’t seem to realize it."

Marco: "The Daily failed because what they chose to make, with its huge staffing costs, required far more than their 100,000 subscribers to be financially sustainable. And it didn’t attract more subscribers because what they chose to make was, itself, deeply flawed."
> At least with the (democratic) government, I will have some control

Citizen votes are non-binding. Politicians can do whatever they want once elected.

The vast majority of people don't even pay attention to what they do once in office, unless it's particularly bad.

Then once in office they don't have to face the consequences of reelection for 4-6 years.

Government transparency is getting better thanks to technology. But at the same time there are more and more 500-page bills that even the politicians don't read. And more agencies with ever growing power who operate in secrecy.

Transparency exists in corporations because they must operate in a market of both investors and customers. Both of those require visible results. In both the short and long term.

Governments are not result-driven. The negative effects of most policies often take effect long after the politican is gone.

In addition, the opportunity cost of Government backed economic and social policies are notoriously difficult to track. But arguably even if they were, based on recent political debates where things like the Fiscal cliff were not even mentioned, I doubt it would matter.

> I don't deny that a larger audience may be better, but it adds overhead to support more platforms, so focusing on just one can be an advantage

Publishers should however consider approaching their readers with respect. Limiting access to content with platform is not pleasant for those who don't use that platform. In case of physical books / magazines there is no such limitation. So spending some more resources to avoid offending potential readers is a worthy goal. Plus as I said that overhead doesn't sound to be that dramatic - what's so difficult in providing a link to a PDF?

No, whereas pylint promotes a good style, same space between function definitions, etc. this is something that is heavily missing in perl. Python also doesn't have (or actually it's almost never used) global variables and goto and all that crap that people still use in perl code. On of the first things i do when having to work on others perl code is to run Critic and first fix the myriad of warnings that come up. With Pylint it's typically just some minor stuff. With Critic it's typically some major stuff that's plainly wrong.

I think what most people observe as "raining" is when the ground is wet and the sky is overbearingly gray, looking like it will rain. From indoors, it's quite hard to determine if it is actually raining, and to most people there isn't much difference. The lack of sun and wet ground is more bothersome than precipitation.

If it rains 50% of days, that means the ground is almost always wet, and the sky is almost always dark and cloudy. To most people, that is rainy weather. Furthermore, the air is often misty and wet, but would not be measurable precipitation.

I'd love to see a similar analysis of sunshine. I did find on most days in the Seattle winter, the sun would peak through for a few hours, though usually too low in the sky to promote much Vitamin D production.

Seattle has amazing natural beauty, and sometimes the weather can be excellent even in the winter. Summers are flawless. However arguing that it doesn't "rain all the time" in the winter in Seattle might depend on whether your definition of raining is as meteorologist, or on whether you have to wear waterproof shoes and carry an umbrella.
Uber, AirBnB, et al. are pushing it to extreme, but it's an example of an idea that laws (at least in long-term) follow the will of the society. Like anti-smoking laws, which happened only after we mostly figured out that cigarettes harm people. I just hope that the will of society will do the same to MAFIAA-influenced regulations, as they clearly go against the way people want to use technology and share information.

That's the main reason I believe private entrepreneurs can have a bigger say in making the world a better place than governments, and starting a business is better than going into politics if you want to change something.

I have Lenovo T420 as work laptop, it costs nearly as much as my unibody 13" MBP did in 2010, except it has a shitty trackpad, keyboard (which isn't backlit, instead they have this useless lamp at the top of the screen), the screen doesn't have auto-brightness which I consider a must now and it overall has this cheap, plastic feel to it. The top border of the display separated from it's backing after a couple months (and I'm usually gentle with my tech), the optical drive eject button is positioned in such a way that you always accidentally trigger the open action - everyone at my job has this problem, I think it's because the eject button is the right most object on the side and very easily pushed.

If I paid that much of my own money I'd be very pissed. Given my experience, I will not be buying Lenovo machines. Dell however was quite a nice workhorse, still not in the same category as MBPs though.

I think the title of the original was being criticized (righly), not the title you chose for the HN post.
Uber and other mobile-dispatched-and-paid services typically feature identity/GPS tracking of each driver and passenger, by device and photo.

I predict that driver-on-passenger crime will be less frequent, and easier to prosecute, in such a system, compared to the traditional-licensed taxis sector. And also: compared to 'gypsy' cabs that successfully pretend to be licensed cabs, because of supply and authentication problems inherent to the traditional system (but obsoleted by Uber-like services).

So if/when an unfortunate event occurs, the right response will likely be: his new system is already doing better than the traditionally-regulated category, and so no special regulations are needed – just vigorous investigation and prosecution of individual crimes.
Interesting, would you mind breaking down the costs a bit more (e.g., fixed costs, cost per journalist, how many journalists vs support staff like IT personnel)?
Instead of creating aliases, I'm using z (https://github.com/rupa/z) for that. You use it instead of cd to navigate to the most frequently used directories anywhere.
But it is The Daily's fault. Care to explain why it's Apple or their platform's fault? I ask because the article that Gruber linked to sure as hell didn't, and I suspect that you are merely perpetuating lazy internet memes.

Flash is still a great platform for developing games while HTML5 catches up in terms of a consistent cross platform experience. However I find the open source development tools to be much more convenient. For e.g. FlashDevelop is an excellent IDE if don't require the animation tools. Haxe is a great strictly typed language that has a fast compiler targeting Flash.

Considering c is 63,198 AU/yr, and Voyager 1's only about 123 AU away, there's still a lot of room left for future engineers in increasing the speed of our devices to very quickly surpass it. Will we achieve even a hundredth of c within the next 100 years? Depends.
I figured. Thanks for the links though, lots of interesting stuff there.

(I remember seeing this video when it was posted months ago as well, but thanks for clarifying the timing as to which event came first.)
I am wondering why it is as it is. I think it may be because of perls abundance of short cryptic symbols that people feel somehow "proud" to 1) know what "while(<>){print if($.==2 || $& && !$x++); $.=0 if (/^--+$/)}" does and 2) to make it even shorter. Because with )(!§&/$?(=)% with hell a lot of meanings you could write entire perl scripts based on special characters.

A good example is http://www.nntp.perl.org/group/perl.beginners/2009/01/msg106... that i just found googling for perl one liners. The OP want's to know what this line does, the first answer is "you can make it even shorter!". Somewhat explains what i try to say ;)

Surely there is a lot of clean perl code out there but from my experience at customers (i'm consultant) what happens in-house in some development departments looks very very very different. Then again i've seen a lot broken, half-tested and unmaintained CPAN modules as well.

>Are there any relatively common tasks that will actually be prevented by this level of ghosting? I don't mean "it's a bit annoying", I mean "this task is no longer feasible".

Apple bills their computers as "the computers you do stuff with". They have a long history in the professional media/content creation business, and their marketing campaigns and advertizements for the last several years were based on bringing those capabilities to the mainstream.

If nothing else, iPhoto, iMovie, and GarageBand come with every Mac.

With those issues, two of the potential uses for the computer–which comes bundled with Apple software to do them–become infeasible for anyone who cares if they exist at all.

I hear that the LEGO Mindstorms kits are good for simple, programmable robots.

See it that way: A bad programmer that can use such a variety of difficult to read symbols in a language (which perl clearly has) will just use all of them and the result will be horrible to read and understand. Also, often times python really has one obivous way to do a specific thing. Last time i was googling for some perl code (i think it was for some array handling) i have found at least 10 equally good totally different way on perlmonks in one thread. That's not bad per se but it promotes that every one uses another line of code and the bad ones choose the lines that may have unintended side effects but work in 90% of the usecases.

1. The guy who posted TFA is not a "professional"-- at least, not a professional graphics designer, professional photographer, or any other profession where ghosting would be an issue.

2. Apple has always been a consumer-focused company, not a company focused on businesses or professionals.

3. For as long as Apple has existed, there have been "Apple has jumped the shark this year because of X" posts. Always. They're almost as common as the Mac vs. PC posts, and almost as boring.

oh, and:

4. Do the words "passive matrix LCD" mean anything to you? I used to have an Apple laptop where the screen ghosted so much, even moving the pointer was like playing a game of "snake." And this was the way it was designed. Kids today really have nothing to complain about, except paying too much for something they didn't need in the first place.

What makes you think that is the case? It looks equivalent to a "git merge --no-ff <feature-branch>" to me. The feature branch is then merged with master (or whatever the target branch was) and would appear if you ran "git branch [-r] --merged" from the target branch which is a good hint that it can be safely deleted.

I find The Economist's online edition to be technically good, and of course the content from that "newspaper" is great as well.

If you went no farther than The Economist's software, with $1mm/yr of writing focusing (as Gruber suggests) on opinion, news, and analysis, I'd be willing to pay $20-30/yr.

I would prefer something like Foreign Affairs, although slightly more timely (weekly or biweekly, vs bimonthly).
As he says in the video, they can't locate the position but can approximate distance from signal strength measurements.

To get location information would require one of the following:
1) An array of antennas pointing in different directions, this is certainly possible, but not using the single built in antenna in a smartphone.

2) The device to know its own location and to transmit this to the phone. This would only be as accurate as GPS and would use significantly more power.

Using signal strength to approximate distance is reasonable, but the location of the sensor, nearby objects and the design of the phone's antenna will all affect the measurements.
I'm sure it's the Daily's own fault if they failed. I was making fun of the fact that Gruber's posts always defend Apple.
