As someone who leads an analytics team in the advertising industry I have to say this title and the studies they are referencing are not accurate to the entire industry at all.

Advertising absolutely works when done right. The effect on brand consideration, shopping behavior, and incremental purchase value can be quantified. The most sophisticated advertisers spend a lot of money to accurately track and ensure their campaigns are lifting their desires metrics.

Now to the eBay study they reference. That study is specific to eBay, a large brand that has spent hundreds of millions a year on advertising for many years and is a top web property visited by a significant percent of the online audience. For eBay it turns out brand search marketing largely does not have a contribution as most of their shoppers are likely going to buy anyway.

Trying to generalize that to a brand that did not have the amount of equity, natural SEO rankings, and established shopping behaviors would be foolhardy. Additionally if you dig deeper into the eBay study they did find a positive effect for the small percent of users that are new shoppers to eBay. They just happen to be a relatively small percent of the audience reached with the spend given the large size of eBay.

In the digital space there is a huge variability in performance based on the type of ad, the nature of the targeting, the product being advertised, the creative message, etc. Trying to generalize to all online advertising without controlling for the kind of brand, product being sold, current marketing positioning, and campaign objective seems a bit naive.

In our work we find huge variability in performance even within the same web property dependent on the placement of the ad within the site and the unit being served. We measure how long the ad was on the page, how many users actually hovered over it in view, and then the incremental lift of exposed users compared to control group. Turns out if you properly optimize to maximize true ad viewing and engagement you will see lifts in brand response, digital visitation, and shopping metrics compared to the control.

In fact I'd much rather have money for digital advertising any day over old fashioned ads with the limited tracking possible. I know how many people saw our spot on the YouTube home page, how long they spent interacting with it, and can tell you exactly what they were interested in. For that TV spot I don't know if you were watching, skipping, going to the bathroom, looking at your phone, or any number of other factors which could diminish effectiveness.

TLDR; online advertising works when done correctly and absolutely can be measured
Explain to me how automated transportation replaces biking?
Erlang doesn't look like it Just Works on Windows and Visual Studio. No Intellisense? Productivity--. No MSVC build? Productivity--. It better be that much better to sacrifice that much engineering productivity relative to it's competitors.

In contrast...Node.js? Works. C/C++? Works. MongoDB? Works. etc. At least they could pretend to make an effort.

EDIT: It's 2014, serious tools need to integrate into IDEs and support inline development, debugging, and testing. It's ridiculous to be coding in simple text editors that lack the ability to deploy and debug code on the fly. Save that slog for live environments.
The company I previously worked at advertised a position to work alongside me at my same level doing the same work, the salary being offered was 50% higher than my salary at the time.

I took this to my manager and all he had to say was "there's nothing I can do, I don't set these things"

It's downright insulting to see this kind of behaviour.
The WWLLN has been around for awhile doing this sort of thing, though not in nearly as accessible a manner: http://wwlln.net/

They use VLF radio detection to triangulate strikes.
There's also often a quid pro quo with partners. At a long ago employer, I remember when we decided to drop out of a show put on by a large ISV who was important to some big accounts but certainly wasn't a source for new business, our CEO got a call from their CEO and pretty much was told to get on board if we wanted the partnership to continue.

I've also seen big shows that creaked along for years until one or two major vendors in the space decided to stop exhibiting. Suddenly the emperor had no clothes and the show didn't last much longer.

(There's also just a lot of momentum and interest behind the status quo. Mind you, there can be a lot of value in sessions for attendees and, generally, just getting people together in one place. But a lot of money also goes into staging trade shows that's arguably not really necessary except for appearances sake.)
the range on those detectors is amazing.
In four total weeks in London, I can count on 1 hand the number of cyclists I saw.

Never been to Tokyo or Singapore, but if they're anything like Seoul, where I've spent months, riding a bike in the streets is both playing Russian Roulette and virtually impossible on account of the bad terrain (and for pretty much all the same reasons I brought up earlier). You also have almost no place to store them given the size of the average apartment. Outside of dedicated parks, I've almost never seen a person on a bike their either.

I've been to dozens of countries on almost every continent, and bikes are a very uncommon mode of transportation. That's why places like the Netherlands, where it is common, are so notable. If it was common, we wouldn't care.

Rather than being snarky, what's your suggestion for overcoming these practical and social issues?
As a long time bike commuter, I've never liked the "protected" bike lanes put in in Chicago. The few streets they work WELL on were already great cycling routes before they had the lanes, and the other streets they haven't worked well on they are often repurposed by whatever entity decides to repurpose them.

Several of them are somehow converted into school children drop off zones for cars during the morning (i.e., at the time that people should be commuting on them they're made even more dangerous - Des Plaines Ave near the church school for example) And of course despite multiple calls out to advocacy groups and local leadership, nothing seems to beat the "for the children" argument, despite the fact that what it's really doing is "for the traffic" more than anything.

That's one of many examples though, but the short of it is - things like protected bike lanes ignore the real problems in urban commuting, of which there are essentially four, in my opinion:

1 - Traffic is too fast - The basic speed limit unless posted otherwise, in the city of Chicago is 30mph. this speed limit is nearly NEVER enforced by police (Hello free revenue stream?) and traffic down major streets regularly goes at 50+ mph.

2 - Traffic is too slow - congested streets cause just as many problems as speeding. Being in a car when you're stuck in stop light to stop light traffic is infuriating. People are constantly looking for a move they can make to avoid it. Even with a bike lane, cars will constantly try to pass on the right, use what's supposed to be parking to make moves towards turning early, etc. This has been the source of my own collisions with automobiles 4/5 times I've had them in 10 years.

3 - Lack of a safe place to stow the bike. Any respectable bike will cost $500.00 and up. Sure, you can get some used single speed or old ten speed for less, but walk into any shop, and you won't see much below that. Locking those outside, especially on a regular schedule, makes them not last very long. (not to mention weather, which while often fine to do a short ride in, all day exposed to can wreak havoc on even a great bike).

4 - The whole, stinky at work, work stigma, aging building infrastructure problem. Sure, a few downtown offices have showers, but it's certainly the exception (spoken as a developer who's worked in many offices over the years) and in some companies being "that guy" seems to have it's own negative connotations.

Want to spend that bike-focused infrastructure money well? Start offering tax breaks to companies providing showers (I'd hear this was a thing once, but never found any proof of it), or safe places to store bicycles indoors. Want to create more of that bike-focused infrastructure money? Start enforcing speed limit laws that exist already, and start looking more towards traffic patterns for cars as a whole, and stick to shared lanes and painted lanes.
Considering how expensive point-of-sale systems are, I'm not surprised that these systems are running old, vulnerable software. Heck, there are still ATMs running OS/2 Warp in the United States; the only reason people don't hack those is because it's so obscure.

My father still uses a small pre-computer cash register to this day; I've had no luck convincing him to buy a new computerized one so he can accept credit cards.

And Australia, which has amazing weather for cycling, mostly flat cities, wide roads, has hardly any cyclists. Because it is so cheap to drive.
Go can also compile to a static binary. Haskell almost (libgmp is the only hard dependency).
>I'd like to know why you consider it abhorrent

1. I am a Turing fan-boy. 2. I am also a big advocate of the fact that Software IS hardware. And in reality, all computation is software ('hardware' is merely the materials engineering that implements the computational 'logic' e.g. Electrical Engineering for modern-day computers). Classifying a Turing Machine as a 'hardware' abstraction is just so not true. It's an Abstract Computational Machine -- it abstracts the concept of computation (not the fact that it uses a Tape, etc.) and as I said earlier: computation IS software.

>I'm not sure what the concern is with every object having a morphism

Every program is a function type, and every type is an object. Thus, (type-theoretically at least) every object within the category is also a morphism and vice-versa. Considering Turing Completeness, we can create any program and thus any type from other types (it itself being a type). Thus, the Category can be achieved as a whole as a 'program-type (function type)' since everything within the category is a type itself. This creates strange paradoxes, where the category (and all sub-categories and functors between them) are inside the category itself. (Side-thought: I wonder though if you could address decision problems with this craziness.)

>typed linear lambda theories

Symmetric Monoidal Categories give rise to Linear Type Theories. However, Braided Monoidal Categories (and especially Monoidal Categories) allow for more. The Rosetta Stone diagram in the conclusion section doesn't restrict the category class (if I remember correctly).

>I tend to find this paper really illuminating and instructive

Me too. :)

>but instead an exploration of lambda theories.

hehe, I'm not a fan of Lambda Theories (but please excuse my bias).

EDIT: An explanation for the downvote would be appreciated. Thanks. :)
What sexist comment did Chad make?
No, bike riding is incredibly uncommon the world over. Is an inconvenient, slow, tiring way to travel in anyplace without a good climate or near perfect terrain.

Edit: keep down voting in spite of your own ignorance. I've been lots of places the world over, and not seen lots of bikes outside of very very few areas with near perfect conditions for them.
I've copied the plaintext here for you.

> It's because our cities have been laid out with the premise in mind that everyone will have cars.

Some cities are like that, and others aren't. People can vote with their feet. Guess which one people like better? (Hint: People have been moving out of dense cities for 100 years now.)

Are you planning on forcing people to accommodate themselves to your definition of the perfect city?

> We have disparate clusters/districts related to activities like 'work', 'play', 'shop', and 'sleep', rather than having these constructs evenly interspersed.

Is that supposed to be a bad thing? The world is not sim-city. Not everyone wants to live near a shopping area.

> We have supermarkets instead of markets.

Markets are not large enough to carry everything, so when I lived in a place like that I never went to the market, so I got the worst of both worlds: High density (i.e. traffic) plus a long drive.

I moved out.

You are acting as if the layout of cities was a commandment given from on high, but actually cities are laid out as they are because people like it that way.
About the only part of the U.S. with a workable decent climate for most of the year is Silicon Valley.
As a biker, are you saying you have seen more bikes break the law than car drivers? Not where I live in Australia.
How fmap constructs it's value depends on how that type implements the functor typeclass I believe.
Google Maps actually already does some of the things listed in the article (such as indicating multiple alternatives between two particular stops) but its ability to do so depends on the quality of the data provided by the local transit agencies.
In 20 years, I've only worked in one place that had a shower. To me, for practical and obvious reasons, it sounds like no number of bike lanes will get people riding if that isn't solved.
That's interesting. To me, J2EE is a pic failure in turns of developer enthusiasm (might be considered successful because of usage). I am yet to meet a developer who likes to code in J2EE and they would take every opportunity to jump ship to just about anything. That said, mine is a startup world and nobody I know writes new code in J2EE.
I agree with you, again for me this comes from personal cycling experience and seeing a lot of bikers ride dangerously. My take is that the traffic fails to accommodate cyclists sufficiently, which creates a kind of 'impedance mismatch' so to speak.

For example, say a bus overtakes a cyclist and stops 40m in front. A car would signal, wait for a space, turn, then catch up to the traffic. For a bike, it needs to signal, wait for a space, then start peddling, which is very much slower than a car. A car following the bike needs to slow down creating a hazard. I experience this many times in the past few months, especially where one has to peddle up hill.

The reason I noticed this is because recently I tried electric bikes, they greatly help with the initial peddling which I feel make me less of a target for cars. An easier route for a normal bike is to take the side walk and avoid that hazard all together.

Another is when waiting for green light, bikers tend to peddle before the traffic light turns green because they can get a head start peddling. Personally I feel pressured to do so to avoid the cars behind me overtaking dangerously.
People who need Erlang, know about Erlang and don't need "onramps". Dumbing it down hasn't been necessary for Amazon and Facebook to adopt it, among many.

Not every bicycle is intended to be driven by toddlers, so not every bicycle needs mounts where you attach the training wheels.
Those special two way bike lanes with the signals, down Dearborn I presume you mean, are the thing I avoid the most riding north/south. The "pedestrian extension" effect you mentioned is the sole reason why.

We have another big problem at least in Chicago, and that's that it's such a polarizing issue that it's easy to make news articles and stir up so much inflammatory debate that any sensible lawmaker is likely terrified to even approach that territory. (See the tribune and John Kass' infamously baiting articles that get tons of hits)
My larger point is that painting up bike lanes is probably the last of the issues in the "let's get people biking" discussion.
I both agree and disagree with you. As a bike commuter in San Francisco, which is a much more bike friendly city than New York where I used to commute to Union Square from Park Slope, I definitely experience the "traffic too fast" thing. I am lucky to have an office now where I can store my bike in our office (we have dedicated bike parking inside on the 11th floor where our office is), but I also know that is rare. However, it does make it more likely that I'll ride to work (and do every day).

Regarding getting to work sweaty, why not ride slower? Sure, you might live in a hotter place than I do, but if you reduce your speed you'll sweat less. I think many of us on bikes are still getting out of the lead foot mentality of driving a car.

Traffic too fast can be controlled. Traffic too slow? That's one that can be solved by separated bike lanes. Look at the Netherlands and how they solve it. I personally hate the combined bike/traffic sections of Market St in San Francisco. Those are the most terrifying 7 blocks of my commute.
One of the most striking things to me is this sentence: "Trustwave and other companies that get hired to investigate breaches involving card data is that far too many point-of-sale breaches start when the thieves abuse some kind of remote access tool installed on the point-of-sale device itself."

We have an incredibly secure and successful piece of remote access software (ssh) that is used on billions of computers and yet that sentence exists. It seems that sometimes it's not just an engineering problem.
Kind of confusing how they call anonymous functions "pure functions". Having function literals is great, but calling them pure functions is going to be frustrating for anyone coming from a background in FP.
If anyone wants to point to a place where the latest tech boom has benefited the environment, the best place to look in my opinion is public transit. Catching a bus or train, which once held a significant learning curve is now a couple taps on a smartphone or a text message away.

I remember going back to San Francisco with a couple friends and they were just as able to navigate muni as I was, even though they had never lived there.
I saw the analogy in some book: imagine there is a shoemaker, who has no access to good materials and good tools. The result of course is that his shoes are terrible. And why you can understand all of the reasons why shoes are terrible—they are still terrible.
Good data is hard to get. Yup.
Or do you think the data on Higgs boson was easy to get?
I'm surprised these PoS systems aren't managed with automatic updates, since the merchant service providers (along with the banks) are usually the ones losing money if they get hit with chargebacks.
Munich has similar bike lanes and it seems to work out pretty well, though I only spent a few days there.
Electric cars are a very uncommon mode of transportation too. Should we therefor not care about promoting that method of transportation? No, because then the status quo would never change.

The article discussed in this thread brings up one suggestion for overcoming practical issues. There are many, many more (proven) solutions to choose from -- when you make bicycle transportation pleasant enough, people will start using it.

If the "social issues" you talk about are because there's a group of people who thinks transportation by bicycle is uncivilized, I think it is a matter of education and tolerance. Once using bikes is common in a country, you will see that the only social issues are about people having unjustified fears (about the implications of considering bicycles as a method of transportation during city planning) and there are no real social issues other than people being dicks.
It controls serving of probably more than 50% of world smartphone to internet data traffic. That is pretty successful.

It handles tens of billions of messages per day for Whatsapp, that is successful.

Riak and RabbitMQ handle a lot of data and messages for many companies.

Ejabberd and derivatives are probably the default enterprise chat/XMPP backends.

If anything one can argue it is more successful than any of those technologies.

What are node's success stories? Paypal, Walmart, New York times. I haven't been following but those are ones I remember using it.
Wow really? You spent 4 weeks in London and never saw a cyclist? Were you out in the suburbs? I spent a bunch of time in London and saw a TON of cyclists in central London. Many of them took the train out to where I was staying too (outside Brixton).

I also don't buy the "small apartments" thing. We live in a 650sq ft apartment and have 4 bikes hung up on our wall. Where there's a will, there's a way.
Is there any other country that is built for individual automobile transportation the way the US is?

I haven't been to France but have you been to Amsterdam, Berlin or Copenhagen?

It is perfectly valid to criticize US without it being "the US is strange and stupid"
Please show how to produce the following string (which is matched by that regex) from the grammar (without the quotes):

" People have been moving out of dense cities for 100 years now."

Data to support this? Every study I've seen recently shows that people are moving INTO cities, not out of them.
How would you describe the climate in Copenhagen?
Not if more people committed to riding bikes...
I can go 60 miles per hour in my car.

The average speed of cyclists in Copenhagen is under 10 miles per hour. Add in a couple long hills and you are at 6-8 times faster on any given day.
> Try searching for reviews on a laptop you find at Best Buy. There are none. The model number is 10+ random characters and completely meaningless.

This is a problem for a number of users but I think you got the reasoning a bit wrong.

The real reason this is done is for the purpose of reducing price-match deals when other retailers have a discount on the same model.

I for one have never faced a problem finding reviews as a number of tech reviewers mention all model numbers in their posts.

Also, this is not limited to Windows PCs but to most high(er) ticket electronics like televisions.

> This is one of the (many) refreshing things about Apple. Macbook Pro is Macbook Pro until the next refresh.

While partially true, Apple does have multiple model numbers within the same generation, they just don't tell the customers about it. The models are based on hardware used. This makes any review somewhat inaccurate as different customers who bought the same product based on the same reviews from the same retailer may get marginally different hardware.

ex. Macbook Pro - Retina - mid-2012 - came with either a LG display or a Samsung. The LG displays had problems with image retention. A few Samsung had a yellow tint. And at the time of purchase the customer had no way to know which one they were buying.

Personally this is extremely problematic.
