Berlin’s Fernsehturm and Sutro Tower

I realized today that despite spending a lot of time looking at each of them, I didn’t know which was taller: Berlin’s Fernsehturm or Sutro Tower. Quick answer is the TV Tower is quite a bit taller if you don’t take into account the elevation of Mount Sutro, but in order to visualize it better I stuck them next to each other, at scale.

Chalking “STOP NSA SPYING” on Snowden’s old street

IMG_20140825_133947While I was on vacation in Hawaii, my friends and I took a trip to Edward Snowden’s former house in the Waipahu area. Not much to see—it’s just a house in a residential neighborhood—but we were nearby and thought it’d be fun to make the trip. Here’s a picture of the five of us posed out in front (from left to right, that’s me, Sarah Jeong, Marcia Hofmann, Kashmir Hill, and Trevor Timm).

We hatched an idea to come back with sidewalk chalk, and on the day I left for the airport we stopped by and I took to the street. Here are the results.


Rick Perry, meet Warby Parker

As I just announced on Twitter: it turns out the mugshot from Rick Perry’s recent indictment works just fine in the Warby Parker virtual glasses try-on tool.

Media literacy and #Ferguson livestreams

I’ve been glued to the news unfolding in Ferguson, Missouri all this week. There is a movement growing as a lot of ugly forces in American life are becoming impossible for a certain mainstream to continue ignoring. At the same time, it’s been really remarkable from a media perspective: a lot of the story built on social media, and in a lot of ways that continues to be the most thorough and timely source of information.

Media literacy is more important than ever with a story like this. A lot of the most important sources of info don’t have the traditional trappings of authority; people are independent or reporting from previously unknown organizations, they’re livestreaming or posting photos to Twitter, articles are interspersed with a constant stream of updates.

Readers and viewers need a command of media literacy not just to evaluate what news is timely and important, but also to contribute to the conversation where necessary.

I pulled this clip out of a livestream from Argus Radio. I’m not sure most people can do that with the tools they know how to use, which is a real shame. Being able to copy and paste from video like from text is an essential part of media literacy in 2014, and will only get more important.

I use a tool called youtube-dl to download videos, and then edit with a combination of different pieces of software. If you don’t know where to start, look at the software that comes with your operating system. On Mac OS X, for example, Quicktime Player has some basic trimming and clipping functions to allow for basic editing right out of the box.

It goes beyond video, of course. One journalist, a sports editor in DC, used a Google Maps screencap and what appears to be OS X’s Preview app to make an annotated map of the areas in Ferguson where the major news stories are taking place.

And late last week, as many were upset about a proposed Day Of Rage coinciding with an earlier and more community-driven initiative called the National Moment of Silence, my friend Sarah Jeong did a very basic image edit that drove that point home. These things don’t have to be complex; a simple image got this point picked up by major media outlets.

Different people will find different things that work for them. But if you can’t interact with the media you’re observing, it can be hard to have a voice.

An email signature to encourage encryption use

A great way to encourage more ubiquitous email encryption is to let people you’re emailing know that you’re equipped to use it, and that they can be too.

Some people use PGP signatures for that purpose, but inline signatures can be off-putting to people who don’t know what they are, and attachments can be similarly confusing. (Not to mention that, as XKCD notes, the security benefits are pretty slim.)

A one-line addition to an email signature is a good compromise. I propose the following:

I prefer to use encrypted email. My public key fingerprint is 4FF3 AA1B D29E 1638 32DE  C765 9433 5F88 9A36 7709. Learn how to encrypt your email with the Email Self Defense guide.

In my case, because I’ve got my key available on an HTTPS site, I’d probably link to it directly as well.

This system isn’t perfect, and in particular is not a very secure way to distribute your fingerprint. But it could be a good nudge to people who might be considering learning about email encryption while flagging you as somebody who might be able to help, and especially if you post to publicly archived mailing lists, it’s a way of getting your fingerprint tied to your emails in lots of places.
