If US educational leaders were to consult their Swedish colleagues, the advice they’d likely get is not to remove digital technology whole cloth. “The goal is recalibration rather than reversal,” wrote Fälth. This was echoed in a statement sent to Undark by the Swedish Ministry of Education and Research: The “Swedish government believes that digitalization is fundamentally important and beneficial, but the use of digital tools in schools must be carried out carefully and thoughtfully.”

Just posting another article on this…

I’ve been reading and listening to Cal Newport for almost a decade now, and I’m a big fan of his work. His books, including Deep Work, Digital Minimalism and A World Without Email have been foundational in my thinking about how we use technology in our work and in our daily lives. He has a popular podcast as well, which I listen to regularly, much to my kids’ chagrin.

So, I was pretty excited to see his byline on the front page of the NYTimes Opinion section today – Stop Filling your Mind With Digital Doritos.

(I have no idea why they change the online title of this article to be worse… or at least more boring.)

It is quite a long essay, ironic, perhaps given that the thesis is that we’ve lost our ability to concentrate. It is well worth a read, because while he mostly focuses on education and the working world, there is a broader point about our society’s ability to focus and hold deep complex thoughts. Look no further than our current AI-Slop Social Media administration and I hope you begin to see the problem of placing people who are not deep-thinkers in charge of our government.

A diminished ability to use our brains also has concerning personal effects. Thinking is what lets us make sense of information in a complicated world. As president, Abraham Lincoln used to regularly retreat to his cottage, on the grounds of the Soldiers’ Home in the heights above Washington, to find the solitude needed to think intensively about the decisions facing him as commander in chief. A contemporaneous letter from a Treasury employee visiting Lincoln at the cottage during these years describes finding the president “reposed in a broad chair, one leg hanging over its arm. He seemed to be in deep thought.”

This was one of my favorite quotes from the article, mostly because the thought of how President Lincoln was sitting in this chair thinking makes me laugh.

I’m interested to know someone’s earnest argument against this article. I don’t believe that “It’s too hard” to make these changes is a valid argument. There’s a lot at stake. I’m interested in building a coalition here.

Besides the fact that the presentation of this page is awesome, this article is an excellent overview of where we are with the NSA.

NSA files decoded: Edward Snowden’s surveillance revelations explained

This is a great list of things, pretty similar to what I wrote about (and better written, as well)

The complete guide to not being that idiot who got the company hacked – Quartz

“Every week there are headlines about a company getting its email, website, Twitter accounts or something else hacked. The reason? In a word: Employees. “

Revelations about the NSA’s practices continue to be released, and each additional leak is more and more disturbing to me. It’s not disturbing to me in the sense that I have secrets that I need to hide from the government. Rather, I think it serves as a big wake up call about how a democracy should work, all of our safe-computing practices in general.

I believe in the liberty of your thoughts, writing, and communications. I don’t think any of us want to have all of our letters opened by the postal service, our library lending history turned over to the NSA or our Amazon.com shopping history shared with the government.

It is important to remember that emails are plaintext (like postcards), your SMS messages, and unencrypted browsing sessions are all out in the open. What you share on Facebook, on twitter, on your blog (hah!) are essentially public information.

In conjunction, there is a big difference between communications you intend for your friends, loved ones, colleagues, and the communications you intend for the public internet. Given this, we should treat these different classes of communications differently.

Finally, many of us carry a computing device with us at all times. These devices typically carry our entire address books, email, social networks. In short, our digital lives.

So, I’ve been reading a lot encryption and security recently (some people in this house might say I’ve been a little obsessed) and I wanted to share a few easy things that I think can enhance your computing security. These essentially fall in to two categories – physical security and data security.

Physical Security

The physical security recommendations I have are pretty simple:

• Put a passcode on your phone and tables. (How to add a passcode on iPhone or iPad)
• Turn off auto-login on your laptops and desktops, and enable the screen-saver lock. (System Preferences -> Users & Groups for the auto-login setting. Security and Privacy for the screensaver lock)
• Use FileVault or similar on your laptops and desktops.

FileVault is a feature I recently enabled on our computers. Basically it encrypts the entire hard drive so that if someone stole your laptop, they would be unable to extract any information from it. Apparently, people in the security community are unsure if there are NSA backdoors in FileVault, but for your average thief, it’s going to prevent your information from getting out there.

If you decide to enable FileVault, make sure you copy down the recovery key – there is no way to recover your data if you forget your password or lose that key. I’ve printed it (on paper) and stored the key in a safe location.

The other two items are common sense to me, but according to Apple (when they released the new fingerprint login feature, so appropriate skepticism applies) only 50% of people put a passcode on their phones.

Now as far as the security of your data in transit, things get a little more difficult, as each type of communication is a little different, and has serious tradeoffs.

Email, Chat, Text Messaging, Web Browsing

I’m only going to recommend things that I actually use. One could go crazy, using Tor all the time, but I find it to be a bit over the top.

Web Browsing
Install the https everywhere plugin for Firefox or Chrome. This will encrypt your browser communications wherever possible. Simple.

Email

I’m using GnuPG/PGP – but no one else is. Well, not no one, but basically no one I know and communicate with regularly. And why not? Perhaps because it has a couple flaws in day-to-day use:

1. Your phone/tablet probably can’t read the encrypted message easily. There are solutions I have not explored yet. However, the first post I found regarding Android phones was 19 steps long. The post concludes with, “Thats all it takes”. Unfortunately, this is about 16 steps longer than most people will endure.
2. If you want to read your email via webmail (Gmail, perhaps) you will have a very hard time doing so.

And yet, Email is important to me. Emails to friends and family are basically letters, and when I write a “real” email, I think it carries nearly the same weight as an actual handwritten letter. Granted, there are plenty of throw-away emails sent, one-liners probably better suited for chat or text messaging, but email still holds a reserved spot in my mind. I’ve decided I’m going to stop abusing my email (at least personal email – what do I do about work email?)

So, if you are on a Mac, I invite you to check out GPGTools. It is fairly straightforward, they have a nice “Where do I begin” setup guide and GPG Tools will integrate with a variety of Mac mail clients.

Basically, once set up you can sign or encrypt your email. Signing sends the email in plaintext, but allows the recipient to confirm that it came from you and was not modified in transit. Encrypted email does the same, and prevents it from being read in transit. Signed emails can be read on the phone or in webmail, but they include a little block of text with the digital signature.

I put up a new page containing my PGP Public Key, if you’d like to add it to your keyring and communicate with me over email securely, please do. It’s kind of fun in a James Bond-ian way as well.

Chat and Text Messaging

If you’d like to encrypt your instant messaging, download the free Adium for Mac (clients for Linux and Windows exist as well) and enable the encryption feature. Works like a charm.

If you use iMessage (the blue bubbles) on an iPhone, iPad or Computer, your chats are encrypted in transit. Yay! SMS messaging is in plaintext, so between devices, one would have to use a cross-platform messaging app. Too much trouble, I’ll deal with the plaintext nature of these communications.

Summary

There are fairly simple ways to increase the security of your computing, I hope you’ll join me in creating a more secure environment for yourself.

Tons of additional information is available on the subject, but here are a few final resources:

Update

I wrote up this entire post, and then found iPGMail, which appears to be a solution for reading encrypted mail on your iPhone. If so, that would solve one of the major hassles with encrypted email.

This blows my mind…

3D PRINTED RECORD

“I’ve created a technique for converting digital audio files into 3D-printable, 33rpm records and printed a few prototypes that play on ordinary turntables. Though the audio quality is low -the records have a sampling rate of 11kHz (a quarter of typical mp3 audio) and 5-6 bit resolution (less than one thousandth of typical 16 bit resolution)- the audio output is still easily recognizable. These records were printed on an Objet Connex500 resin printer to a precision of 600dpi with 16 micron z axis resolution.”
