Write_As instances

If you would like an easy to use, hassle free blogging platform that respects your freedoms then Write_as may be useful for your needs.

Write_as is software that has lots of features to help you set up a small, lightweight blog, supports multiple blogs from one user account. It also supports ActivityPub to facilitate federation.

You can either self host or join an one of many existing instances:-

WriteAs uses Markdown to add styles to the pages, e.g to make text bold, underlined or add pictures. You can also embed HTML code blocks. This is how this page displays the video below.

There is a video below, hosted on Peertube, to explain more.

Follow write.as on Mastodon to keep up to date or ask questions.

Paignton Library Summer Virtual Code Club 3

So further to the previous post

Lets move on to Python.

Paignton Library will be sending these activities out via Social media using the hashtag #PLAIC_codeclub

If you don't already have an account for either home or school then you can sign up to a free Trinket account at:-

While all activities are here

I appreciate that if you have been following the virtual code club since march. If you have, and you would like to move on then FreeCodeCamp have lots of tutorials:-

You may also want to look at signing up to Repl.it in order to gain collaborative browser based developer environment.

A new feature of Repl.it is Teams. I am currently investigating this.

University of costumed heroes

Software freedom is important as it gives users the power to be in control of the software they use and the hardware it is installed on.

GNU.org defines free software as :

What is Free Software?

Free software means the users have the freedom to run, copy, distribute, study, change and improve the software.

Free software is a matter of liberty, not price. To understand the concept, you should think of “free” as in “free speech”, not as in “free beer”.

More precisely, free software means users of a program have the four essential freedoms:

* The freedom to run the program as you wish, for any purpose (freedom 0). * The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this. * The freedom to redistribute copies so you can help others (freedom 2). * The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

```

The latest Free Software Foundation video hopefully helps illustrate what can happen when you put trust in closed source systems that cannot be subject to scrutiny through access to the source code.

Examples of common free software

You can follow the fsf on the federated social media networks such as Mastodon

Initiatives such as Tech Pledge are also a good idea for getting people to think about how they behave on line and starting to build better, more friendly, respectful communities.

Nethack Vulture scores 10/8/2020

This post will,from time to time be republished, with updates to the score table.

Just sharing my latest scores from Nethack-vulture. I am playing this on FreeBSD.

to generate the score type:

nethack -s at the command line. If you direct this in to a file with nethack -s >score.txt, then this will also include scores from previous games.

Paignton Library Summer Virtual Code Club 2

To continue with the Paignton Library Virtual Code Club.

Paignton Library will be sending these activities out via Social media using the hashtag #PLAIC_codeclub

If you don't already have an account for either home or school then you can sign up to a free scratch account via * Scratch

While all the Scratch Module 1 activities are here

The modules can either be followed as they are, or as with the physical code club, are useful as a guide. If you get stuck or need inspiration how to do things.

We still have the Library Studio up here.

If you share with the Scratch studio, remember to do so safely and not share too much personal information. By sharing you can help others, learn from others and improve your own learning as you go.

I created some of my own instructions, for Scratch 3.0 a while back which are presented below.

updated the above list to point to GitLab rather than GitHub as I am moving away from GitHub as much as possible

Organic Chemistry 6: Benzene Derivatives in Organic-Chemistry

So as an extension to yesterdays post Compound chemistry have an infographic on Benzine derivatives.

Benzine Derivatives

So once you have made a Benzine molecule, this can be easily modified to some of what is presented here.

#chemistry,#organic,#benzene,#Derivatives,#molymod,#modelling,#lookingforwork,#compoundchem

Organic Chemistry: 5 Phenyl Group

As Polystyrene Contains a C6H5 Phenyl group. Before moving on to building this, we can look at similar molecules that also contain this group.

Video should show making of the above compounds with Molymod components.

Tomorrow, I will post a follow up on more benzene based molecules to build. So please keep hold of the C6H6 Benzine model.

If you would like any further help with chemistry (or any other science subject) then I have found ScienceForums to be a very useful, friendly and educational forum.

Organic Chemistry 4 : Plastics

Previous post

Moving on lets have a look at:-

I have built this using Molymods in the video below, Just imagine that the rest of the white atoms (hydrogen from previous video) are in fact green, Chlorine atoms.

You may find Molview helpful for visualising molecules on your computer screen too. This could complement physical building which I find can help understanding further.

I will post a few more videos showing the other molecules in that section of the infographic.

Plastics

#chemistry,#organic,#compoundchemistry,#modeling,#molymod, #education,#plastics,#Polytetrafluoroethylene,#Polytetrafluroethene #monomer,#polymer

**Note: ** Polytetrafluoroethylene. It appears that Polytetrafluroethylene and Polytetrafluroethene are the same molecule, with different spellings depending on if you're using US or GB English.

Organic Chemistry 3 Plastics

Following on from organic-chemistry-2 we have had a look at Alcohols. So will now turn some attention to plastics.

So again we can construct models of plastics in a similar way, the main difference here is that plastics are POLYMERS, which are MONOMERS chained together.

Mono – Single Poly – Multiple

Common plastics

So looking at the above you will notice that they are using n to indicate there is more than 1 in the chain.

So starting with ${C2H2}$ or Ethene, this becomes Polyethene when more monomers are added to the chain.

So in the video below, I construct Ethene and then, in the spirit of Blue Peter, I am then using a few more I made earlier.

You may find Molview helpful for visualising molecules on your computer screen too. This could complement physical building which I find can help understanding further.

I will post a few more videos showing the other molecules in that section of the infographic.
