There’s a better way to SSH. Ditch bastions, keys, and certs with Tailscale (Sponsor)

SSH is no picnic. Managing SSH keys correctly means spending hours distributing, removing, and managing keys. Certificates help, but enterprise CA can be an even bigger headache. What can you do?

Tailscale, a VPN service for secure networks, says it has a better way:

Many organizations already use Tailscale to protect SSH sessions — for example, connecting a work laptop and desktop. Since Tailscale provides the VPN and lets you set access controls to restrict communications between devices, the next step is to get rid of SSH keys completely and use your Tailscale identity instead. See how it’s done on the Tailscale blog.

Instagram gets worse with dark patterns lifted from Tiktok (6 minute read)

Instagram is testing features with some users that make the app more like TikTok. The new feed shows as much algorithmically targeted video content as possible and tries to maximize engagement wherever practical. It removes the ability for users to mute or unmute videos by tapping on them. The feed has also switched from an infinite scroll to an item-by-item flipping style. When users reach the end of their organic content, the feed now presents half an algorithmically selected post to encourage users to continue.

Ancient Lava Caves in Hawai'i Are Teeming With Mysterious Life Forms (3 minute read)

Scientists recently found a marvelous assortment of novel microbes thriving in the geothermal caves, lava tubes, and volcanic vents of Hawai'i. These underground structures were formed up to 800 years ago and receive little or no sunlight. They can also harbor toxic minerals and gases. The older sites hosted more diverse populations than those less than 400 years old, but the younger sites had more complex microbe interactions. Many more details about the microbes are available in the article.
