As my family settles into a whole new city and community, I’ve been eagerly exploring a variety of sites and services for discovering new gems and getting to know our area. And while our recent cross-country move is what inspired me to seek out such tools, I’ve quickly realized these same resources could be every bit as useful in any scenario—whether you’re visiting a new locale or even just looking for fresh inspiration in your existing everyday terrain.

This tool lets users send fake legal letters that look real—without a lawyer

If you can’t afford a lawyer, it turns out there’s nothing stopping you from sending a scary-looking letter that, at first glance, seems to come from one—and hoping the recipient doesn’t read the fine print too closely.

That’s the idea behind Heavyweight, a tool that lets you take any complaint and format it with an official-looking letterhead, without ever actually claiming to be from a real lawyer.

‘Door kick challenge’ goes viral—but cops say the TikTok trend could lead to serious injury

Ding dong ditching has resurfaced as the “door kick challenge.” But this time it could lead to criminal charges and potentially deadly consequences.

Trump is caught in an Epstein web of his own making

What happens when you spend decades seeding salacious stories about evil lurking in the halls of power, demanding evidence to prove basic truths, and questioning the veracity of that evidence once it’s presented?

Elon Musk used to be a movie hero. Now he’s the villain

I recently saw James Gunn’s new Superman movie, and as I sat there in the dark theater, I couldn’t help but think that Nicholas Hoult based his Lex Luthor on Elon Musk.

The rise of the CTO in the age of ‘business unusual’

Years ago, I spent a lot of time making the case for why IT mattered in large enterprises. It’s fair to say the landscape has changed—dramatically.

Where I once had to argue for IT’s strategic importance, I now find myself doing the opposite—pushing back on the exuberant view that technology alone can fix everything from poorly designed processes to unclear roles and responsibilities.

After decades of serving as essential—but often background—enablers of enterprise strate

This new smartphone is designed for old-school physical keyboard lovers

It seems the market has spoken when it comes to phones with physical keyboards. BlackBerry exited the mobile hardware business almost a decade ago, and its licensing partners like TCL appear to have given up on the idea as well. For better or worse, the world now largely runs on people typing and swiping words onto glass surfaces. 

That doesn’t mean the loss doesn’t sting for the diehards.
