I did this in Shanghai circa 2018, when the AQI was horrendous (second pic). Above 100 was common, and an occasional spike above 400. Airnow.gov has Barnegat at 63 and forecast for 100

Lotta talk now about burner phones (and nerds saying what isn't). You don't need to go super cloak and dagger for decent risk reduction. But if you want to, listen to @eanmeyer.bsky.social and @strandjs.bsky.social from @bhinfosecurity.bsky.social

One of the risk profiles is protesters. For them, and for more users and reasons, iPhone users should turn on Lockdown Mode. In this context, it's about IMSI catchers, which intercept calls. @eff.org just released a tool for this, and it's worth reading about, and using

Spoiler: One of the 5 things is using MFA. It's been a decade since learning this one thing could've prevented John Podesta from losing control of his Gmail. @danielmiessler.bsky.social wrote a great breakdown of options, so this section doesn't reinvent the wheel

The common cyber cliche is about not being faster than a bear, but outrunning the other potential victim. The drier cliche truth is that security is a process. Don't stress over loose ends and TODOs, just come back regularly and eventually do them

Seriously, it works from phone?

Ugh. Well, if anyone who engaged on that thread sees this, I appreciated it

Petitioning Google and NOAA to do the right thing and rename this instead

Google caved, but NOAA Weather Radio is still holding strong with Gulf of Mexico

Shortly after moving to Miami I joined a printmaking studio, just when hurricanes Helene and Milton were coming to Florida. So I got a new radio with weather band and made these shirts, a callback to the 90s ones about Black Sabbath, Slayer, Bob Marley. Wasn't meant to be political, but here we are

Went straight from attending Cyberwarcon virtually to seeing Amy Tan at the Miami Book Fair talking about her new book, THE BACKYARD BIRD CHRONICLES. Since she’s starting off with her birding beginnings and a blue jay, here’s one from our apartment in Cambridge last year

An oldie but goodie from this weeks' Hacks/Hackers newsletter. Love to roll my eyes at this mixup, but also kinda love it

Remember when CNN rang in the new year from Bangkok, Taiwan?
