Fun bash stuff

While these are not bash commands, there are a few fun tools.

One is fortune, this displays a random quote on the console or terminal.

fortune
Many pages make a thick book, except for pocket Bibles which are on very
very thin paper.

Another is cowsay which takes an argument and prints a picture of a cow (there are options to change how it looks or to other characters)

cowsay hello
 _______
< hello >
 -------
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||

As with other commands these can be combined

fortune | cowsay

Docker Containers

I don't have any experience with Docker or similar tech, but as this is popular, I am going to try and link to some tutorials for popular services, If these are useful great. I will give this a go at some point, but it will be more for learning rather than production.

K2-18b

I think this Daily Mail article demonstrates how poor journalism is getting in 2025. This is their article on the Planet K2-18b.

While the JWST has found some indications that life may exist on the planet, due to the Hydrogen Atmosphere and also the discovery of

  • Di Methyl Sulfide
  • Dimethyl Disulfide

The WikiPedia article tells a much different story.

Even the first part of this quote is helpful in that it says the press release was irresponsible. And that the data collected so far is not enough to confirm any life.

Astrophysicist and science writer Ethan Siegel denounced the press release as "wildly irresponsible" and astronomer Ryan MacDonald pointed out that the team's analysis was flawed because it only compared a select few chemicals to the data.[5] According to MacDonald, a proper statistical analysis of DMS and DMDS in K2-18b's spectrum would instead give a false positive probability of about 28%, corresponding to a 1σ confidence for the these two chemicals.[5] A 1σ significance does not qualify as a meaningful detection.[5]

The fact that the DM article also somehow has a section where someone has used AI to extrapolate what life may look like is rather ridiculous, as is the fact that according to that, the frog has 3 eyes and looks as it does to allow for the lower light level on the planet, this is odd given the fact the Wikipedia article suggests the light level on K2-18b may be the same or similar as it is on Earth, due to the distance from its star and the size of the star as well as other factors.

I think whoever thinks using AI to extrapolate what alien life may look like is risking their entire science career and credibility and this person was apparently from Cambridge University, so the reputation of Cambridge university is also going to be questioned.

I am baffled as to how much of this gets passed editorial in mainstream press.

In the meantime, if you really want to learn more, I strongly suggest you read actual science papers.

Granted, I think arXiv is pre-prints, but at least these papers are written by people who have a clue as to what they are talking about. It is also essential to be able to dig deeper and do your own research so when asking questions you can refer to decent sources of information.

I think it is also important to remember this planet is >120 light years away, so the information being picked up took >120 years to reach the JWST, therefore we are looking back in time. So it is important to understand that what is there right now in 2025 may be different to what may or may not have been there in 1905 when that light started its journey. Or at least this is how I understand things

If you want to read and have a good laugh, then read the Daily mail and other mainstream media.

More security : fail2ban

Fail2ban is a program that will help you with the security of your system.

There is a tutorial for this at Linux Handbook, so I have quoted the description, or part of, below.

This is where a tool like Fail2Ban comes into picture. Fail2Ban is a free and open source software that helps in securing your Linux server against malicious logins. Fail2Ban will ban the IP (for a certain time) if there is a certain number of failed login attempts. [1]

Gopher 3

I have set up an account on vern.cc which will give me access to a working gopher server. In the meantime, I am working on a gophermap file and some support files to upload alongside it.

As vern.cc already offer gopher as a service, then the directory public_gopher already exists, so it is a case of copying in to there.

So to upload I can use

scp gophermap user@vern.cc:/home/user/public_gopher

Then to view this using a gopher client

gopher gopher://vern.cc/

Which will bring up a menu of users, and you can select zleap from the bottom of the list.

A few more notes

The gophermap file uses TABS, in your text editor you make sure you are using tabs not spaces, in xed (the editor I am using) there is an option in preferences that says use spaces instead of tabs this needs to be turned off.

It then formats the file correctly

spaces vs tabs

Removing users

To remove a user, you can issue the following, as we are no longer setting up a gopher server on the pi, I will just remove the user.

sudo deluser gopher

Which will remove the user, but not that users /home directory, which for the most part is fine if you want to keep hold of the user account data.

For more information and options, consult the man page

man deluser
