Blink: Get Notified When Your Mac Wakes

Blink: Get Notified When Your Mac Wakes

Chances are good that most – if not all – of us leave our computers unattended somewhere, sometime. For me this is at home. Though I generally abide by best practices and shut down before leaving my computer, occasionally I don’t. I can be caught close my MacBook’s lid and heading out the door to run an errand, walk the dog, whatever. I do have some peace of mind that no one is messing with my computer, however. This is…

Smartphone Wi-Fi Security

Recently reader asked me to write a post about the implications of Cellular, Wi-Fi, Bluetooth, and Near Field Communication (NFC) radios in smartphones, and the privacy and security implications of each.

How To: Diceware Passwords

How To: Diceware Passwords

I strongly advocate the use of password managers. In October I will be reviewing and providing tutorials for a number of password managers as part of my National Cyber Security Awareness Month posts. Even with password managers, however, you still need to remember – and be able to manually enter – at least a few passwords.

ProtonMail Premium Review

ProtonMail Premium Review

Email is a service that we all rely on. Finding an email provider that promises a good balance of privacy, security, and convenience is a fraught proposition, however. As readers here doubtlessly know, I have huge privacy concerns around email. I hate giving out my real email address if possible, because it equates to attack surface (more on this later). I also hate using the same email for multiple services, but this creates major convenience problems. And I can’t store…

Death and Passwords

Death and Passwords

I recently received an email from my close friend, Gabriel. He is deployed to a very dangerous corner of the globe. In it he asked me to handle some of his digital affairs in the event of his death. Of course I agreed, and the conversation started a train of thought: if I died, what would happen to all my electronic files? With no way to access these, everything I have created would be forever lost upon my death. Worse…

Lock Safari NYC – New York, New York!

Lock Safari NYC – New York, New York!

I recently had the chance to spend a few days in New York, New York.  This was a personal trip, and I covered a lot of ground. This time, I actually managed to focus on the locks I saw, and I saw some good ones on Lock Safari NYC. I noticed some interesting things about New York’s locks. First, there are a LOT of high-security locks on the street. In Manhattan (LES, SoHo, Midtown, Theatre District) and Brooklyn (including DUMBO…
