I'm now doing UNIX administration (not full time) for more than 25 years. And yet only today I learned about a cli tool called "comm". 🤯

Ever needed to know which lines in a text file are not in another file , or which are in both?

comm A B compares two sorted text files and outputs three columns: one with lines only in A, one with lines only in B and one only with lines in both files.

And you can switch off each column with cli arguments.

I want the years back I fought with shell scripts!

You do not need techy skills or lots of money to set up your own Fediverse server! It starts from about $10 a month via a managed hosting company that does all the techy stuff for you.

I run a site for non-techy people who want to have their own servers at:

➡️ https://growyourown.services

You can follow the site's account at @homegrown. It includes a guide to making your own Mastodon server in 10 steps:

Most of this guide applies to any Fedi server on managed hosting.

Ethernet | RJ45 clip to secure/repair/fix broken tab by guss67

This clip was design to fix/repair/secure the broken or loose tab of a RJ45 Ethernet connector and avoid crimping. Designed to prevent from moving, wiggling, falling from the connector and easy to install.UPDATE v.4.9 | 28/01/2021Added the 3 following files which have slightly wider body (0.25mm) than 4.7 version and small upgrade on the tip.1. "4.9.nf.supported" (extension) comes "with supports" for the ones are not very familiar with. But I still prefer S3D's supports.2. "4.9.nf" (extension) with "no fillet", to make it easier printing with supports.3. "4.9" (extension) with fillet, for "smooth edges". On FDM printers isn't that much noticeable.UPDATE v.4.7 | 01/01/2021Added another version with "no fillet" (".nf" extension), actually it has sharp edges to make it easier printing with supports.PrintingSuggested printing orientation is the one as the files are stored, why?Printing the tab from the base to the tip in X-Y axis makes it stronger and more flexible since its printed in one continued string.If you change the orientation with the tip on top then tab's base will start from the bottom and builds up while the Z axis is sticking the rest of it till the tip. With this orientation the tab has more possibilities to brake since Z layers don't bond the same as the method I suggested.*If you have another solution let me know.Supports Supports needed and you need to be experienced with good slicer settings. Also attention needed when removing them from the actual print.Or you can print the file with "4.9.nf.supported" (extension) which comes with supports. But I still prefer S3D's supports.Installation note:1.Before install the "printed clip" check the left overs of the broken tab. If it is too long the tip of the "printed clip" might not click underneath the left-over. So, I suggest to leave a length of the broken tab about "0,5-1,0mm". If the broken tad left-over is to small or cuted flash then the printed one might not click and hopefully that would work well, haven't tested that scenario.2.Follow the sketches to install the "printed clip", also while sliding in if you find it a bit hard some wiggling might help.*You may call it the "ScorpioNet" or "Devil's Network Tail"!

I wrote about ActivityPub, and why Elon Musk might have saved social networks by buying Twitter — just not at all in the way he meant to https://www.theverge.com/2023/4/20/23689570/activitypub-protocol-standard-social-network
Can ActivityPub save the internet?

Mozilla, Meta, Medium, Flipboard, Tumblr, and so many other companies are betting that the future of social networks looks more like email than it does Elon Musk’s Twitter. And they’re betting on a little-known protocol to make it happen.

"Q. How does COVID-19 damage the brain, and can the damage be permanent?

A. (...) We now know that, unfortunately, COVID can damage the brain in many ways. When people first become sick from the virus, they may develop encephalitis — inflammation of the brain — causing confusion, difficulty concentrating, and memory problems. COVID also can trigger the onset of new psychological disorders such as severe depression or anxiety. It can even cause people to become psychotic — to see and hear things that aren't there and to believe things that aren't true. It often damages the brain's autonomic nervous system, leading to abnormalities in heart rate and blood pressure.

In addition, the virus that causes COVID can infect and injure the linings of blood vessels and make blood clot more easily. These two things can lead to strokes and heart attacks, even in young people."
