• OSTechNix ☛ How To Prevent Eye Strain Using Safe Eyes In Linux

  If you spend long hours working at a computer, taking regular breaks is strongly recommended to prevent eye strain. Prolonged screen time can cause eye fatigue, dryness, and discomfort, making it important to give your eyes regular rest.

  Fortunately, Linux offers several utilities that can remind you to take periodic breaks. Safe Eyes is one such application, designed to help reduce eye strain by encouraging regular breaks during extended computer use.

  In this tutorial, we’ll explore Safe Eyes, its key features, and how to install and use it on Linux.

• Adam Young: Find the IP address of a machine I just booted

  I am booting VMs via qemu (no libvirt) and sometimes they don't tell me what IP address they got when booted. 

• Jon Chiappetta: I recently learned of a new IP address space in case you need extra internal routing addresses

  100.64.0.0/10 = 100.64.0.0 - 100.127.255.255

  Thanks to Lawrence Systems who covered his own network setup!

• Why can’t I access 192.168.0.1

  192.168.0.1 is the default address used by many routers to open their admin page, where you can change the Wi-Fi name and password, set up port forwarding or check the connection status. When it will not load, the cause is usually simple.

• [Old] Andy Bell ☛ A highly configurable switch component using modern CSS techniques

  Safari Technology preview has recently added a native switch component with version 185 and 186, which is great! It’s going to be a long while before this is ready to rock on a production website though.

  Still, this collection of demos is worth enjoying. Here’s a video for those who don’t have the latest version of Safari Technology Preview.

• [Old] Gilles Chehade ☛ Decentralised SMTP is for the greater good

  So YES, I’d rather see a lot more people self-host or rely on smaller geolocalized providers, spreading the SMTP network as much as possible across multiple operators in multiple countries. I don’t think everyone should self-host, I just think MORE people should self-host or move away from Big Mailer Corps into ANY other provider… so there is at least a bit of constraint for them to interoperate with operators outside their gang, as well as a financial risk for them IF they suddenly went rogue.

  I’ll say it again: [...]

• HowTo Geek ☛ These 50-year-old Linux commands still beat modern alternatives

  Many Linux commands we still use every day originated with Version 1 Unix, all the way back in 1971. Some still outperform their modern equivalents, either in pure processing speed or in other measures like availability and flexibility.

  Come with me on a trip through the ages, from the very early days of Unix, to see which tools endure, even in the face of stiff competition.
