Review: Go back in time with Cogi to record fleeting moments

Monday, February 9th, 2015

When we watched the State of the Union address with our kids a few weeks ago, 3-year-old Sophie Sue was amazed at how members of Congress were sitting still and listening. They weren’t fidgeting, looking around or running off to play with Legos.

“Wow, they’re doing a good job, right?” said the little Tedesco munchkin.

It was one of those cute family moments when I wished I could go back in time and hit the record button.

So I did.

I tapped the screen of my smartphone and the Cogi Android app captured the last 15 seconds of our conversation. Cogi kept on recording until I tapped the screen again. And I repeated the process through the whole speech, capturing only the highlights of what our kids said.

This is the genius behind Cogi — you only record what you want. And Cogi lets you jump back in time to capture that fleeting moment. Because by the time you realize you want to record something, it’s usually too late.

“I don’t want to record everything,” said Mark Cromack, president and chief technology officer of Santa Barbara-based Cogi Inc. “But by the time I realize I do want to record something, I do need to back up a bit. That’s the cool part.”

The app’s name is about capturing the “cogent idea” and it’s like a DVR for your life. Cogi could help anyone who attends long meetings, school lectures or court hearings. You can also get creative with it. I’ve started to use Cogi during car rides with the kids when they’re being funny. Cromack said bird watchers use it to record bird calls. Lifehacker called it one of the best recording apps for Android.

Mark Cromack

Cromack

I interviewed Cromack last week to ask how the company came up with the clever idea for Cogi, discuss a couple things I see as limitations, and learn what new features are on the horizon. Cromack is an avid Cogi evangelist who said he, his co-founder and his son thought of the idea years ago before anyone knew how useful smartphones would become.

“Imagine a world where you got, let’s say, a lapel pin,” Cromack said. “You could just tap it that moment when something interesting happens. Or better yet, it just magically knew that something was cogent to you.

“Well, that’s an interesting dream. Roll that back to some degree of reality. What could we achieve nowadays?”

Then smartphones became a thing. Today, the Cogi app is available on iTunes and Google Play. Here’s how the app works:

You open Cogi and a button on the screen says “start session.”

Cogi Start Session Screen

Tap on that and start a new session. A session is when Cogi is listening but not actively recording. The button now says “tap to highlight.”

Cogi Tap to Highlight Screen

When you hear something you want to keep, tap the highlight button. Cogi then starts to actively record, and it goes back in time to record the previous audio it was listening to before you hit the button. You have the option to go back five, 15, 30 or 45 seconds in time.

Cogi Capturing Screen

You can repeat this process as often as you like. When you’re done with the session, hold down the button. Cogi lets you add notes, tags and photos to each session. You can upload sessions or audio clips to services such as Evernote.

That’s all free. Cogi makes money by offering a monthly membership service that allows you to record phone calls and receive transcripts of recordings for a fee.

While you could use it to record an entire interview and soak up every word, Cogi really shines when you only want to capture the highlights of long conversations or events.

One problem with Cogi is that it only records in Windows .wav files. The quality is great but the large files hog memory. Cromack said Cogi will soon add options to record in other formats.

“That’s coming out within probably the next public release,” he said. “It has to.” Cromack said the company knows users want that option but it’s one item on a long list of improvements the company is working on.

“We’ve known about it,” he said. “The issue was just one of, ‘Let’s get something out there that works and it’s solid and has that cool experience.’”

Another quibble: When the screen is off or when you’re using other apps, Cogi no longer passively listens during a session. (If you’re actively recording, Cogi will still capture audio.) The screen dims after awhile to save battery life. But if I’m taking notes or something I don’t want to accidentally brush the screen and screw something up. Or maybe I’ll need to use another app during a session.

By the time I realize I do want to record something, I do need to back up a bit. That’s the cool part.”

Cromack sounded receptive to that critique but declined to discuss details about whether it will be addressed in upcoming updates, or whether Cogi will branch out beyond audio into the world of video. He later sent me an email saying the company is developing a version of the app that lets users record sessions even when the screen is off.

“Based on your input and questions, we already have implemented a private version of the app that continues to record/monitor when the screen is off,” he wrote. “Control is passed to the volume keys and feedback to the LEDs (on Android). This not only provides a more subtle way of triggering Cogi, but it dramatically improves power savings achieved as compared to the current dim screen feature. As such, we’ll be delivering this ‘power user feature,’ no pun intended, in a future release (soon). We still have some things to work out with this feature, as this proof of concept version was to just see how it *might* work.”

Cromack said that later this year Cogi will offer cloud services to members. This would enable users to share highlights, notes and photos with others who could view that material in a web browser.

“All of that is part of Cogi cloud services,” Cromack said. “It’s not available today but it’s going to be out.”

If demand increases for Cogi’s transcription services for members, Cromack said the company plans to include other languages and translation services. Cogi is also going to be updated to support enhancements for larger devices, such as tablets and iPads. “There’s a long laundry list of really exciting capabilities,” he said.

For me, Cogi offers a way to capture fleeting moments not only for news stories, but for the times with my kids when they say something funny or insightful. Parents think they’ll remember every moment of their children growing up. Cogi can help make that happen — even for the moments we miss. Just hit that highlight button, upload your session, and make a family journal.

Now you’ll never forget that time your daughter watched the State of the Union address.


Up in Flames: Flares wasting natural gas in the Eagle Ford Shale

Sunday, December 21st, 2014

If you drive through the bustling oil patch of the Eagle Ford Shale near San Antonio, it won’t take long to find the surreal sight of flares burning natural gas like perpetual bonfires.

Natural gas is cheap. Pipelines are expensive. So instead of collecting the fossil fuel, many oil and gas operators build tall, metallic spires called flare stacks to burn the gas and release it into the Texas sky.

Natural gas flareFor years, no one could say with any certainty how much natural gas was going to waste. Everyone knew flaring in shale country was a problem. But officials at the Railroad Commission of Texas, the state agency that oversees the oil and gas industry, had never released figures showing how much was being burned in the Eagle Ford.

Instead, the agency released only statewide figures showing the overall volume of flaring was low compared to overall production — about one percent.

Whenever a government agency touts rosy statistics, there’s probably a database behind those numbers. And if you obtain that raw data, you might be able to figure out what’s really going on.

Today’s Express-News story about flares burning 20 billion cubic feet of natural gas so far in 2014 is a good reminder of the value of public databases — and why journalists need to get their hands on them to analyze the records for themselves.

There’s no question analyzing data can be a lot of work. We filed an open records request with the Railroad Commission for a copy of the flaring data in the spring of 2013. It’s a huge database of monthly reports showing how much oil and gas is produced in Texas and where those hydrocarbons go. Flaring and venting are one of the “disposition” categories in the data.

I drove to the agency’s Austin headquarters with a flash drive that could handle the enormous database. It was a beast — more than 25 gigabytes of 85 million records. All that summer we used software to convert the Railroad Commission’s archaic data to CSV files, a format we could use in the newsroom. After that, it took weeks to crunch the numbers and uncover the hidden pitfalls.

Why go through the hassle? Why should frazzled journalists take the time to learn how to analyze data? Don’t we have enough to do?

The answers is, journalists need to know a lot of skills — how to interview people, how to write clearly, how to find information. Analyzing public data should be a part of that skill set. It opens doors to stories that couldn’t otherwise be told. This is what journalism is all about.

When we were finished reviewing the flaring data, our analysis showed that the volume of flared gas in Texas had increased by 400 percent since 2009. And most of that gas came from the Eagle Ford Shale near San Antonio. This chart essentially told the story of flaring in the shale that no one had figured out — not even state officials:

Quantifying the volume of flared gas opened up new questions and possibilities. When Projects Editor David Sheppard asked how much air pollution was created by all this flaring, we found out there was a way to calculate an estimate. We obtained emails from the state’s environmental agency, the Texas Commission on Environmental Quality, that showed how to estimate levels of air pollution created by gas flares. Those formulas were based on the volume of flared gas – which we had. So we plugged those numbers into Excel spreadsheets to come up with the amounts of sulfur, volatile organic compounds and other pollutants that came from flaring in the region.

In August, the Express-News published the results of our investigation, Up in Flames. The total volume of wasted gas in the shale from 2009 to 2012 was almost 39 billion cubic feet — enough to meet the annual heating and cooking needs for all 335,700 residential customers who relied on gas last year in CPS Energy’s service area, which includes San Antonio.

Sunday’s story is based on a fresh batch of flaring figures obtained by Express-News Data Editor Joseph Kokenge, who scraped the data directly from the Railroad Commission’s website.

The new numbers for 2013 and 2014 show that flares burned and wasted even more of the fossil fuel. In the first seven months of 2014, more than 20 billion cubic feet of gas went up in smoke — enough to fuel CPS Energy’s 800 megawatt Rio Nogales power plant during the same time frame.

New search tips for 2014 from Google research scientist Daniel Russell

Monday, July 14th, 2014

I couldn’t attend the 2014 Investigative Reporters and Editors conference in San Francisco this year. But thankfully, Google researcher Daniel Russell was there. He gave another excellent presentation about search-engine strategies and posted his advice online.

Daniel Russell, research scientist for GoogleAs the Uber Tech Lead at Google, Dan studies how people search the web. He started sharing little-known search techniques three years ago at the IRE conference in Boston. Since then he’s annually offered tips at IRE that can help everyone — not just reporters — find exactly what they’re searching for online.

Here are some of Dan’s new strategies and tools for 2014, and a recap of the most useful tips from his past presentations that I’ve used myself. You can check out posts about his other talks here and here.

Go back in time

One of the coolest new tools offered by Google this year allows you to jump in a time machine in Google Maps’ Street View.

Let’s say you’re walking around downtown San Antonio and you’re curious about the site of a historic building on Commerce Street across from Main Plaza. An inferno destroyed the building a few years ago and now there’s nothing but a vacant lot:

Commerce street without the Wolfson Building in Google Maps

In Google Street View, click on the clock symbol in the corner of the screen to check out how that spot looked over the years. In this case, you can look at what the Wolfson Building looked like before the catastrophic fire:

Google map image of the Wolfson Building in downtown San Antonio

The Wall Street Journal used this time-machine effect to illustrate dramatic growth in Brooklyn.

The cool thing about this is how you can pan around and get different perspectives of the sites you’re interested in.

Gallery of Google Map Mashups

The Google Maps Gallery allows organizations to mesh their data with Google maps. All these mashups are searchable, and Google links to the original sources if you want to download the information yourself.

Let’s say you’re curious about which counties in the United States are prone to tornado strikes. A search of “tornado” in the Google Maps Gallery shows a map based on federal data showing tornado strikes, total property damage, injuries and deaths by county:

Wildcards in Google Maps

Type an asterisk in the search bar of Google Maps and it will show you every business and significant, named place it knows about in the area you’re viewing.

If you plan on using any of this information in a news story, you’ll want to take steps to confirm what you’re seeing in the map. But this is a really quick way to get a sense of what’s in the area.

For example, if you’re writing about the Wolfson Building fire and want to get a quick idea of what businesses were nearby, in Google Maps, focus on the site on Commerce Street and try the wildcard search:

Force Google to search for certain words

By far the most common search function I use in Google is “intext,” which Russell discussed at his first presentation in Boston.

Sometimes Google tries to be too helpful. It changes your search terms and uses words it thinks you’re searching for– not the words you’re actually searching for.

And sometimes the websites in Google’s search results don’t include all your search terms because Google decided those pages might still be relevant.

That might be OK for general searches. But it’s not very helpful if you’re looking for pages with specific terms or words with unusual spellings. How do you make Google search for those exact words?

Typing intext:[keyword] (with no space on either side of the colon) might be Google’s least-known search operations, but it’s one of Dan’s favorites. It forces the search term to be in the body of the website.

If you’re researching the story of the Wolfson Building, for example, you’ll probably want to make sure that Google always includes that unique name in the search results. Typing intext:Wolfson San Antonio will force Google to include the term “Wolfson.”

Intext also works with phrases in quotes. So typing intext:”Wolfson Building” will strong-arm Google into showing you that exact phrase.

To learn more details about Google’s search operators, check out my post about his talk in Boston where he gave us a treasure-trove of advice.

Customized site searches

Google’s site search let’s you search for information on a particular website. Typing site:mysanantonio.com “Wolfson Building” would show pages with that phrase that were published by the San Antonio Express-News. But what if you wanted to regularly check what other local news outlets published in the San Antonio area?

Google can focus on multiple websites with its custom search engine. You tell Google which websites to search, save your settings and Google creates a link to the custom search page. Now you can search those specific websites any time.

This technique is handy for anyone interested in a particular beat or issue. I created this customized search of San Antonio media and blogs to quickly see how news organizations are covering a story. You can also sort the results by time or relevance, and conduct an image search with the terms you want on those websites.

Control F is your friend

Not everyone knows this so it’s worth repeating: Type “Control F” in Windows or “Command F” on a Mac to launch the “find” function in your browser to locate a specific word or phrase on any web page. It’s faster than reading the whole page if you’re looking for something in particular. “If you don’t know this, you’re roughly 12 percent slower in your searches,” Dan said at the IRE conference in Boston.

This year, Dan said useful Chrome extensions expand the usefulness of the “find” function. Let’s say you want to find more than one word. You could type an expression such as Wolfson|Building|Fire to highlight all those words. Handy.

Dan regularly blogs about search strategies by challenging readers with puzzles. It’s a good way to stay in practice. And practice, Dan says, is the best way to hone your search skills.

Telling stories about the unthinkable: How three journalists shined a spotlight on child abuse

Sunday, April 20th, 2014
Sarah Brasse

Sarah Brasse

In February 2009, an 8-year-old girl from Schertz died, alone, of acute appendicitis — a disease that could have easily been treated if caught in time.

In the hours leading up to her death, people concerned about the girl — including officers from the Schertz Police Department — had warned the Texas Department of Child Protective Services that she was a victim of neglect.

CPS didn’t act. And on Feb. 5, 2009, authorities found the girl’s body in a soiled bed.

Her name was Sarah Brasse.

It wasn’t so long ago in Texas that you would have had a tough time learning any of those tragic details.

In fact, according to the state officials in charge of protecting children from abusive adults, you would have had no legal right to even know Brasse’s name.

And you certainly wouldn’t be able to know the agency missed opportunities to help Brasse.

But a decade of diligent reporting by three Express-News journalists shined a spotlight of transparency on tragedies involving Brasse and scores of other children in San Antonio, helping the public understand the unfathomable.

More awesome search tips from Google expert Daniel Russell, with real-world examples

Daniel Russell, research master at Google

When a research scientist at Google offers to show you how to unlock the full potential of the powerful search engine, you pay attention.

Last year Daniel Russell spoke at the Investigative Reporters and Editors conference in Boston. Dan showed us search techniques that can make anyone a better researcher. Some tips I already knew. Others I thought I understood but didn’t. And some I had no idea existed.

I thought Dan’s talk was eye-opening — and others had the same reaction. My post about his presentation last year was widely shared, so there’s enormous interest to learn more about how Google works and how to use it effectively.

You gotta know a little bit about how to make Google dance. This is all mother’s milk for investigative reporters.”

Since that conference a year ago, Dan began offering online classes. I’ve had a year to practice many of these techniques. And about a week ago, Dan spoke again at the IRE conference in San Antonio with even more advice.

“You gotta know a little bit about how to make Google dance,” Dan said at his panel, Digging in with Google. “This is all mother’s milk for investigative reporters.”

I thought it’d be a good idea to compile some of the interesting new techniques, and revisit tips Dan discussed last year with some real-world examples of how journalists used them in actual news stories. Many of these methods also work on other search engines, such as Yahoo! and Bing.

These tips are for journalists, researchers, librarians and anyone else who wants to learn new ways to find information. Google will never replace the importance of shoe-leather reporting — knocking on doors and talking to real people. But Google can help reporters find the right doors to knock on and reveal surprising details about the people you’re talking to. Knowing how to find obscure information on the Internet is a vital skill for any journalist.

How to make stunning time-lapse videos: Q&A with photojournalist Tamir Kalifa

Monday, January 14th, 2013

Freelance photojournalist Tamir Kalifa spent two days working on this stunning time-lapse video of the Texas Legislature’s opening day for the 83rd legislative session. Lawmakers convene in Austin every two years and the event is widely covered by the media. But Kalifa, an intern at the Texas Tribune, captured the energy of the day in a unique, compelling way. I called him to ask how he did it.

Q: This is actually the second time the Texas Tribune has done a time lapse of the opening day of the Texas Legislature.

A: Yeah, that’s correct.

What were you trying to convey in this particular video and how does time lapse help you do that?

Tamir Kalifa

Kalifa

Well, I think that during the off year, the Texas government is sort of hibernating and waiting for this huge burst of energy that happens in the first few months of the year. So really what I wanted to show was the Legislature sort of waking up and coming to life and the excitement that everybody — from the legislators to the lobbyists to the lawyers to everyone’s families — I wanted to get across how people are hugely involved. I just thought doing a time lapse was the most efficient way to show the enormous scale of it. There were thousands and thousands of people swarming around the Capitol. There was an enormous line waiting to get into the House chamber to hear Joe Straus, to see him sworn in again.

It was amazing. I’m a musician in Austin. Free Week is just coming to a close now. You had all these free shows and everybody is clamoring to get in. It’s one in, one out when it gets to capacity. I realized, as I was desperately trying to get into the House to just get a little glimpse of it, there are a lot of Texans who get that kind of enjoyment and excitement out of the government. And that’s awesome. I really wanted to show that and kind of show the grandeur of it. There aren’t that many things in Texas that are as old as the capital. So it’s also cool to showcase it in that way.

How to create maps and charts with Google Fusion Tables

Monday, October 15th, 2012

The friendly folks at the Association of Health Care Journalists held a conference last week in San Antonio, and they invited me to present an introduction about Google Fusion Tables.

If you’re familiar with Microsoft Excel or Access, you might like Fusion Tables. It’s a free tool that allows you to create interactive maps and charts with data. For journalists, this is fantastic. Fusion Tables unlocks the data stuck in your hard drive and lets you easily share it with readers in a compelling format. Check out some great examples at Matt Stiles’ blog, the Daily Viz.

    How to solve impossible problems: Daniel Russell’s awesome Google search techniques

    Thursday, June 21st, 2012

    Daniel Russell stood in front of a crowd of investigative journalists in Boston last week and showed us this picture of a random skyscraper in an unknown city:

    Google challenge by Daniel Russell

    Russell posed a riddle:

    What’s the phone number of the office where this picture was snapped?

    Let that sink in. He wasn’t asking for a phone number for the skyscraper in the picture, which sounds hard enough. He wanted the phone number of the precise office where the photographer was standing when the picture was taken.

    Nothing in that office was even in the photo. Yet in a few minutes, Russell, a research scientist at Google, revealed the answer by paying attention to small details and walking us through a series of smart Google searches.

    Daniel Russell, research scientist for Google“Once you know these tricks, you can solve problems that look impossible,” Russell said.

    There are plenty of Google search cheat sheets floating around. But it’s not often you get to hear advice directly from someone at Google who offers you his favorite search tools, methods and perspectives to help you find the impossible.

    Here are some of my favorite tips shared by Russell at the 2012 Investigative Reporters and Editors conference. Some of these techniques are powerful but obscure; others are well-known but not fully understood by everyone.
