Pro-tip: Make sure your status report scripts are not running on the same server that the applications they are checking on are...when the entire server goes down your scripts will not be running to tell you.

It just dawned on me that this little raspberry pi zero probably has more processing power than all of the Apollo missions combined...

What do those buttons do?

🎉 Welcome to newcomers! 🎉

A few personal tips:

👌 the Fediverse is NOT twitt*r! enjoy a more relaxed, courteous, benevolent way of interacting! you are part of it!

🤚 introduce yourself! also fill bio and post a couple "toots" before following people to have more chance they'll follow back..

👍 favourite and follow generously! This is how to create link around. No algorithm-god is spying on you, telling you who to follow, what to read! \o/

⚠️ many people care about CW... learn about that


Just bought a Raspberry Pi 0W. My very first Pi and probably not my last!

A good favicon can give your site a little more personality and flair.

To make a simple icon pick two colors, a Unicode "geometric shape" character, and a simple shape (square, circle, or rounded square). The simple shape is your container in one color and the Unicode character is centered inside in the other color.

Now your site has a unique visual identifier (with the right meta tags it will show up here)!

If you are not already using a password manager you should. Switching to a password manager is a paradigm shift. Instead of memorizing passwords you should manage them.

There are tons of great password managers out there (many are open source). I use ( My database is stored locally and synced with . Set a strong master password ( and make sure none of your passwords are reused.

Hey can anyone tell me what the criteria for a status showing in my feed when it is a reply to another one?

I thought all replies show to your followers but looking into it more that doesn't seem to be the case. I have a small sample size though. I think it might be when the "reply" (at) mentions someone else that I follow but I'm not entirely sure.

Basically, I feel like I'm eavesdropping on @mike and @kev all the time.

For future reference

1. 3 and 4 are operands so you add them to the stack [3, 4]
2. + is an operator so you pop two numbers from the stack and operate (add them together) then put the result back on the stack [7]
3. 5 and 2 are both operands so add them to the stack [7, 5, 2]
4. - is an operator so you pop two numbers and operate then add the result to the stack [7, 3]
5. * is an operator so you pop two numbers and operate then add the result to the stack [21]

I did a HackerRank quiz for a job today. I had 30 minutes to implement a Reverse Polish Notation calculator... Everything I thought I knew about arithmetic is a lie... For example

3 4 + 5 2 – *

Calculates to 21

It looks like (3 + 4) * (5 – 2) in infix Notation (or the arithmetic you learned in elementary/primary school)

CLI programs are everywhere in Linux. Most have man pages or help text but these can be confusing. If all you want to know is how to enter a valid `tar` command ( you can use!!

Install one of the many `tldr` clients or use the webpage. Simply run `tldr tar` and a nicely formatted list of commands and what they do will be output.

Day 1:

I am normally a quiet person online and I like to take my time to write blog posts. However, you can say quite a bit with 500 characters so I think I will do the challenge here.

I make no promises that toots will come everyday but it might be fun to think of something useful to say everyday(ish) with an end goal in mind.

Today's tip: is a modal editor. If you are stuck hit <esc> a few times and :q<enter> to exit. If that didn't work reboot the computer.

No new post for today but I did give my blog a facelift. New fonts and styles. I also added some new content to my most popular post
