Although incomes are still lower than five years ago, most large metropolitan areas showed at least a tiny gain last year. The patterns suggest that while many regional economies may have turned a corner on the recession, incomes are making a slow advance toward 2009 levels. These charts show data for median household incomes released on Thursday by the Census Bureau in its American Community Survey. Related story.

PlotDevice: Draw with Python

Uma biblioteca de funções em Pyton para construir visualizações de dados.
You’ve been able to visualize data with Python for a while, but Mac application PlotDevice from Christian Swinehart couples code and graphics more tightly. Write code on the right. Watch graphics change on the right.
The application gives you everything you need to start writing programs that draw to a virtual canvas. It features a text editor with syntax highlighting and tab completion plus a zoomable graphics viewer and a variety of export options.
PlotDevice’s simple but comprehensive set of graphics commands will be familiar to users of similar graphics tools like NodeBox or Processing. And if you’re new to programming, you’ll find there’s nothing better than being able to see the results of your code as you learn to think like a computer.
Looks promising. Although when I downloaded it and tried to run it, nothing happened. I’m guessing there’s still compatibility issues to iron out at version 0.9.4. Hopefully that clears up soon. [via Waxy]

Um gráfico de áreas como forma de visualizar como os americanos ocupam o seu tempo ao longo do dia.
»
From Shan Carter, Amanda Cox, Kevin Quealy, and Amy Schoenfeld of The New York Times is this new interactive stacked time series on how different groups in America spend their day. The data itself comes from the American Time Use Survey. The interactive has a similar feel to Martin Wattenberg’s Baby Name Voyager, but it has the NYT pizazz that we’ve all come to know and love.
Explore time use by gender, race, age, education, and employment. View all activities (e.g. work, traveling) or select a specific action to drill down into the graph. From there, you’ll find time aggregates that you can compare against depending on what filter you’ve selected.

What is probabilistic programming?
Posted by Armando Brito Mendes | Filed under materiais para profissionais, software
Uma nova forma de trabalhar com modelos Bayesianos!
«
In this post, I introduce the emerging area of probabilistic programming, showing how probabilistic programs will hopefully make it easier to perform Bayesian-style machine learning, among other applications. Probabilistic programming is an exciting, and growing, area of research, with fantastic people in both AI/ML and PL working together and making big strides. PL methods — including formal semantics, optimization techniques, and forms of static analysis — have proven very useful in advancing this area forward.

Why Content Marketing Fails Presentation Transcript
- Rand Fishkin, Wizard of Moz | @randfish | rand@moz.com Why Content Marketing Fails
- Download this Slide Deck bit.ly/mozcontentfail
- Failure Sucks
- Most Content Efforts Will Fail Spike of hope Flatline of nope
- You’ll Invest with the Best of Intentions
- You’ll Launch with Excitement
- And it Will Suck
- And You Won’t Know Why
- Why Your Content Marketing Will Fail 5 Reasons
- You Believed the Biggest Myth Content Marketing Ever Told the World #1
- We Imagine Content Marketing Works Like This… Let’s go see what’s on the Internet today, shall we?
- I wonder what this post Kieran tweeted is all about.
- That was an interesting. I should sign up for this free ebook download while I’m here!
- And I’ll just fill out their contact form with my information….
- Oh! Better not forget to follow all their social profiles while I’m at it.
- You might laugh, but a lot of companies invest in content marketing on the assumption that this is how it works! Me make content. Humans click. Them buy. Me get money.
- In Reality, It Works Like This: Let’s see what’s on Hacker News… Meh.
- How about Facebook? Oh, right. Baby pictures.
- Let’s try Twitter. Meh.
- Maybe Google+? Actually… This looks kinda interesting.
- After seeing 400+ links I could have clicked, I finally chose this one. It’s a good article, and this example, naturally, resonated
- I wonder why I like this blog so much? About a week later, I caught a link to Beardbrand’s blog.
- No magic trick to grow a thicker beard?! Dammit! I’d followed them on Google+, so I watched this video they shared, too.
- When my lovely wife told me that I might need to look into some mustache wax, I thought of Beardbrand. But I couldn’t remember their name! Lovely Wife Imminent need for mustache wax Who were those guys that made the cool beard stuff?
- So, naturally, I searched Google: Nope Nope Nope Yes!!
- A Perfect Match!
- Say goodbye bushy handlebars!
- This is How Content Marketing Really Works: Caveman Rand explain.
- This is How Content Marketing Really Works: Me Make Content. Humans click. If them like, them remember. Maybe them see more content I make. Visit again. Me build trust, relationship with humans. When them need me product, them come back.
- Content marketing not about convert 1st visit. Or 2nd. Or 3rd. Only foolish humans think it work like this.
- Content marketing about earning familiarity, trust, and relationship.
- Maybe sale come. Maybe not. Smart cave marketer no care. Smart cave marketer know every visit chance to build relationship. Maybe earn fan. That good enough.
- The Obligation Rests on Marketers to Set the Right Expectations with Our Teams & Clients
- You Made Content Without a Community #2
- Does Content Spread Simply Because It’s Really, Really Good? If this content’s really good, it’ll just spread “virally,” right guys?
- OK, Probably Not Ha! That’s a good one, Rand!
- In My Experience, Content Spreads Because It Inspires a Community
- It Reinforces a Belief
- Refutes an Opposing Argument
- Starts (or Renews) a Passionate Discussion
- Is in Someone’s Financial/Promotional Interests
- Leverages Group Inclusion Dynamics
- Makes the Sharer Look Smart/Important/Worldly/Etc
- “Good Enough” Content Often Performs Well when a Community Is Behind It
- Only the Best 0.1% of Content Can Go “Viral” without a Pre-existing Community
- Don’t Bet Your Marketing on Being the 1 in 1,000
- Before you create content, ask the question: “Who will support & amplify this content and why?”
- You Invested in Content Creation, But Not in its Amplification #3
- Content Must Reach People in Order to Reach Its Potential
- Channels for Reaching the Right People Depend on Your Audience
- Most Amplification Methods Fall Into These Three Buckets: Broadcast 1:1 Paid Promotion
- 1) Broadcast (often via Social Media, Email, or through Events)
- 2) 1:1 Outreach (via Social, Email, or In- Person)
- 3) Paid Amplification (many varieties)
- A basic process for getting content amplification right:
- STEP 1: Find Successful Content in Your Niche http://buzzsumo.com
- STEP 2(a): Find Where It’s Being Shared http://buzzsumo.com
- STEP 2(b): Go Beyond Social Networks Google Search and https://freshwebexplorer.moz.com/
- STEP 2(c): Find Who’s Doing the Sharing http://buzzsumo.com

- STEP 3: Copy What’s Working For Them Via http://followerwonk.com
- STEP 4: Build Relationships with Those Who Can Help http://www.slideshare.net/RickTRamos1/why-do-peopleshareonline
- Don’t Treat Amplification as “Fire & Forget.” Experiment, Learn, & Apply. Via http://bit.ly
- Think of Each Channel Like a Muscle to Be Flexed & Strengthened Regularly
- Don’t Forget to Leverage What is Still the Most Powerful Sharing Channel (according to NYT): http://www.slideshare.net/RickTRamos1/why-do-peopleshareonline
- You Ignored Content’s Most Powerful Channel: SEO #4
- Google Search Has Grown Massively ~6 Billion Searches/Day! http://www.statisticbrain.com/google-searches/
- While Search Traffic is Distributed, Social is Highly Concentrated http://www.simplereach.com/blog/facebook-continues-to-be-the-biggest-driver-of-social-traffic/
- You Might Have Seen Re/Code & Buzzfeed Claiming Google Search Traffic Was Dead http://recode.net/2014/02/02/the-year-facebook-blew-past-google/
- Here’s Define Media Group refuting that with data from 87 publishers & 48 billion pageviews http://www.definemg.com/hey-buzzfeed-search-traffic-is-doing-just-fine/
- SEO is Also Critical Because of Intent “Do things” mode “Browse” mode
- When Done Right, Content Marketing is the Rising Tide that Lifts the SEO Ships Without content marketing, it’s incredibly hard to earn the types of links that will confer domain authority & rankings in search engines.
- When Done Right, Content Marketing is the Rising Tide that Lifts the SEO Ships But as content on a site earns links, it helps every other page on that domain rank better in the search engines, lifting the tide!
- At the Very Least, Do Your Keyword Research Be aware that AdWords may not show you all the relevant keywords: http://moz.com/blog/be-careful-using-adwords-for-keyword-research
- Better Yet – Gain a Deep Understanding of How SEO & Content Work Together 4 Posts I’d Recommend: • The Convergence of SEO & Content Marketing • Link Building vs. Content Marketing • How to Build a Content Marketing Strategy • Build & Operate a Content Marketing Machine
- You Gave Up Way Too Soon #5
- The 0.1% Always Look Like Overnight Successes
- In Reality, It Looks More Like This: Geraldine’s Travel Blog: http://everywhereist.com
- Geraldine started her blog in 2009 In Reality, It Looks More Like This:
- For 2 years, she never broke 100 visits/day. In Reality, It Looks More Like This:
- Then she had a few posts get some attention In Reality, It Looks More Like This:
- But traffic fell back down soon after. In Reality, It Looks More Like This:
- This is where most people give up. In Reality, It Looks More Like This:
- These days, she gets 100,000+ visits each month In Reality, It Looks More Like This:
- The Price of Success is Failure after Failure after Failure * Hopefully, each of those failures provides an opportunity to learn. *

Poverty and Race in America
Posted by Armando Brito Mendes | Filed under estatística, mapas SIG's, visualização
Uma boa representação gráfica interactiva
Strategies to tackle poverty, inequality, and neighborhood distress must be informed by local data. The history, geography, and politics of individual metro regions all matter profoundly, and any serious policy strategy must be tailored to local realities.
To help take the policy conversation from the general to the specific, we offer a new mapping tool. It lets you explore changes from 1980 to 2010 in where poor people of different races and ethnicities lived, for every metropolitan region nationwide.
Understanding how the geography of poverty has changed can provide essential context for answering questions like: Are some poor neighborhoods isolated from the region’s job opportunities? What would it take to connect them? Where should family support services be targeted? Which neighborhoods should be prioritized for improvements in essential amenities and opportunities? How can poor people across the metro landscape be better connected to the services and opportunities they seek?
For metro regions to systematically reduce poverty and expand opportunity, local civic and political leaders, advocates, and practitioners should start by sitting down together to understand the evolving realities of poverty, race, and place in their communities. We hope our maps help catalyze these conversations.
