Hacking The Electric Grid Is Damned Hard | FiveThirtyEight
The nightmare is easy enough to imagine. Nefarious baddies sit in a dark room, illuminated by the green glow of a computer screen. Meanwhile, technicians watch in horror from somewhere in the Midwest as they lose control of their electrical systems. And, suddenly, hundreds of thousands, even millions of Americans are plunged into darkness.
That scene was evoked in recent weeks as federal security experts at the Department of Homeland Security warned that state-sponsored hackers have targeted more than American elections — they’re after the electric grid, too. They’ve gotten “to the point where they could have thrown switches,” a DHS official told The Wall Street Journal. Both DHS and the FBI have linked these attacks to Russia — which was already pinned as the culprit in two attacks that shut down power to hundreds of thousands of people in Ukraine two Decembers in a row, in 2015 and 2016. It’s all very urgent — a high-risk crisis that must be solved immediately.

The Best Extension Cords for Your Home and Garage: Reviews by Wirecutter | A New York Times Company
After more than 20 hours researching over 44 different extension cords, talking with safety experts, and testing six of the most promising for flexibility in zero-degree temps, we recommend the U.S. Wire & Cable 50 FT. Extreme All-Weather Extension Cord. It’s the most flexible cord we tested, it’s durable in all types of weather, it won’t break down if dragged through oil or grease, and it makes a strong connection—all of which add up to a cord that should last for years even in the harshest environments.
Our pick
U.S. Wire & Cable 50 FT. Extreme All-Weather Extension Cord
The best extension cord
With a solid power rating and durable construction, this cord can safely handle any job around a home or garage. Plus, it’s the most flexible cord we’ve tested, even in freezing temps.
$41 from Amazon
Because the U.S. Wire & Cable 50 FT. Extreme All-Weather Extension Cord is the most flexible cord we’ve ever tried, it is easy to work with whether you’re in the height of summer heat or the depths of a near-zero-degree winter. The thick, 12-gauge wires inside are rated to handle up to 15 amps—as much as most residential breakers will allow—making it safe to use with most tools and equipment in the US. The outlet has a small LED that lights up when the cord is live. If you’re going to own only one extension cord, the 50-foot version is versatile enough to maneuver across a two-car garage, run between two rooms indoors, or stretch deep into a yard outside. This same cord is also available in a 25-foot length if you want something more manageable, and a 100-foot length if you need more range but want to avoid daisy-chaining cords.

How to Pick the Best Extension Cord at the Hardware Store: Reviews by Wirecutter | A New York Times Company
The extension cords you’ll find for sale online are better quality and cost less than the ones generally stocked at brick-and-mortar hardware stores. If you can wait a day or two for shipping, buying online is the way to go. But that’s not particularly helpful advice if you’re in the middle of a project and need an extension cord right now. If you’re going to have only one cord, focus on indoor/outdoor extension cords—generally the ones in bright colors—and follow the tips laid out here to snag the best cord among the limited options in the store. If you’re looking for an indoor cord just to extend your phone charger or plug in a lamp, the guidelines are a little different.
Buy longer than you think you’ll need
When you’re guessing how long of an extension cord you need, leave yourself extra room for error and buy the next longest cord. Not only is a longer cord more convenient—it’s annoying to just barely reach your work area—-but it’s safer too. That’s because you’re not supposed to daisy-chain extension cords, connecting one to another. The extra length of multiple cords plugged in to each other (without thicker wires to make up for the distance) adds electrical resistance between the outlet and the thing you’re trying to power. Added resistance can in turn cause voltage drops that will make equipment like drills, saws, and vacuums run at lower power. The extra resistance of daisy-chaining cords can also cause additional heat to build up along the way, increasing the risk of one of the cords melting or even starting a fire.
