What the WannaCry ransomworm means for you

The ongoing challenge for women in high-tech companies

Save yourself, save your corporate assets, by blocking spearphishing

Ping! chimes the email software. There are 15 new messages. One is from your boss, calling you by name, and telling him to give you feedback ASAP on a new budget for your department. There’s an attachment. You click on it. Hmm, the file…

Flame decals add 20-25 whp to your car’s performance

It has been proven, beyond any doubt whatsoever, that flame decals add 20-25 whp (wheel horsepower) to your vehicle, and of course even more bhp (brake horsepower). I know it's proven because I read it on the Internet, and everything we read…

Why am I being spammed by the American Bar Association?

IANAL — I am not an attorney. I've never studied law, or even been inside a law school. I have a cousin who is an attorney, and quite a few close friends. But IANAL. So why am I on the American Bar Association's email list? I am not a member…

No security plan? It’s like riding a bicycle in traffic in the rain without a helmet

Every company should have formal processes for implementing cybersecurity. That includes evaluating systems, describing activities, testing those policies, and authorizing action. After all, in this area, businesses can’t afford to wing it,…

Self-inflicted public relations disasters: United Airlines, Pepsi, Tanium, Uber

There are public-relations disasters… and there are self-inflicted public-relations disasters. Those are arguably the worst, and it’s been a meaningful couple of weeks for them, both in the general world and in the technology industry. In…

Manage the network, Hal

Some large percentage of IT and security tasks and alerts require simple responses. On a small network, there aren’t many alerts, and so administrators can easily accommodate them: Fixing a connection here, approving external VPN access there,…

Look who’s talking – and controlling your home speech-enabled technology

“Alexa! Unlock the front door!” No, that won’t work, even if you have an intelligent lock designed to work with the Amazon Echo. That’s because Amazon is smart enough to know that someone could shout those five words into an open window,…

Email clients and 3D paint applications do not belong in operating system releases

No, no, no, no, no! The email client updates in the 10.12.4 update to macOS Sierra is everything that’s wrong with operating systems today. And so is the planned inclusion of an innovative, fun-sounding 3D painter as part of next week’s…

This is a great piece of unclaimed-money spam. Normally I redact the email addresses – but these are far too juicy to censor, especially the "from" address. Merely because the spam links to a genuine web page, such as this bio for Secretary…

Bring a friend to worship services with you

Judaism is a communal religion. We celebrate together, we mourn together, we worship together, we learn together, and we play together. The sages taught, for example, that you can't study Torah on your own. We need 10 Jewish adults, a minyan,…
