'As much as I like using it, I just can't trust it.'The Samsung Galaxy Fold, reviewed again: Hard to love, even harder to hate

Yeah, we're back here again. Samsung's Galaxy Fold is one of those devices that inspires adoration and annoyance at the same time. Its foldable design means you can carry around a tablet in your pocket and get plenty of work done along the way. The Fold's power and flexibility are nothing short of intoxicating, but it leaves much to be desired.

Closed, it's chunky and clumsy, and Chris Velazco has serious concerns about how well its main screen will hold up over time -- our review unit's display developed dead and stuck pixels out of the blue, and there are other units with more pronounced blemishes. The Galaxy Fold offers a glimpse at the future of smartphones and gives Samsung a potent foundation to build on, but almost no one should consider buying one right now.

The hit returns from the void.'Fortnite' Chapter 2 is a new world with water and fishing

Fortnite returns from black-hole darkness with a major overhaul. As you're reading this, Fortnite Chapter 2 will have debuted an all-new map and, judging by the trailer, there are some fresh features centering around water, including boats, swimming and fishing.

It can still accelerate from 0 to 60 in 3.5 seconds and hit a top speed of 155 MPH.Porsche unveils the mid-range Taycan 4S EV

The Taycan 4S is a mid-range version of Porsche's electric sports car. It will deliver up to 420 kW (around 630 horsepower), compared to 500 kW for the Taycan Turbo and 560 kW for the Turbo S.

It's now up for order at $103,800 for the base Taycan 4S and $110,380 with the 93.4 kWh Performance Battery Plus package. That's a lot more reasonable than the $150,900 and $185,000 prices of the Taycan Turbo and Turbo S, respectively.

Sudo make me a sandwich.One of Linux's most important commands had a glaring security flaw

If you've used the command line in Linux or a Unix-based platform like macOS, you're probably familiar with the "sudo" command, which lets you run tasks with different (usually elevated) permissions than you'd otherwise have. It's powerful, but it was apparently too powerful until now. Developers have fixed a sudo flaw that lets you claim root-level access even if the configuration explicitly forbids it.

Linux users can update to a newer sudo package (1.8.28 or later) to fix the flaw. You might not be immediately vulnerable as any attacker will need to have command line control over your system before they can even consider exploiting the flaw -- at that point, you probably have larger problems.
