Getting Hydrogen out of banana peels

Getting Hydrogen out of banana peels

This is interesting, and potentially a good way to make use of waste material. I have included a few links below, and the article link is in the main links below.

It would also be interesting to figure out if a school has such a Xenon lamp, should be possible to try and reproduce this in a school lab. I would guess the Hydrogen gas could be collected if the mass was in put in say a boillng tube, with a bung, and glass tube to a collection tube, then the Hydrogen could be collected and tested for with a lighted splint, so you would listen for the 'pop' made when the Hydrogen ignites. So on a small scale it would prove that Hydrogen can be produced.

UPDATE 25/2/2022

I have found an update to this, from the Royal Society of Chemistry article here

LibreAdventure Testing 2

LibreAdventure Testing 2

Just been helping with more LibreAdventure testing. Please see my previous post if you are unsure, what this is.

So last week, we found a bug when we were in close proximity to another user,, the video chat didn't work, This has now been fixed for the office areas. The bug is still there, if a users enters the conference areas. A report ticket has been submitted about this.

More of the same next week, hopefully with a few more people testing.

Zone of Proximal Development

Zone of Proximal Development

I decided to write this, in an attempt to address some issues that I have when contributing to projects. such as free software projects or engaging in the related communities.

As I am currently working as a teaching assistant, our work is based on theories of learning etc. Therefore we follow research and ideas such as Zone of Proximal Development by Lev Vygotsky,

So how is this applicable to contributing to software? The simple answer is people seem to assume that the person who is trying to undertake a task has the same level of understanding as others.

Most of my Open University study was around Science. Therefore using tools such as git, is hardly something that I do daily. I can, just about.

  • git pull
  • git commit -m “message”
  • git add
  • git push

Which for me is sufficient.

On a similar note is tasks like key signing. For most people people seem to use gnupg and a mail client plugin for this. Their mail client can implement this for signing or encrypting e-mails. Since Thunderbird 78, Thunderbird has integrated OpenPGP which is great, only it hides a lot of the complexity,in the back ground, this makes what would probably be a simple tasks much more complex for those who don't really understand what they are doing.

Again, there is an assumption people can 'just do things'

So within ZPD

  • Task a Learner Cannot Accomplish With Assistance
  • Tasks a Learner Can Accomplish With Assistance
  • Tasks a Learner Can Accomplish Without Assistance

So for the most part, we should not assume a learner, user or potential contributor can perform all the tasks that is being asked. We need to figure out what they know first and try and help them provide us with what we need.

In general it is far easier to provide face to face support, which is not possible in many cases.

I think as a community, we sometimes need to take a step back and remember what it was like when WE were first learning something new, it is difficult at first, till we find that one tool that make things easier. Until then we probably struggled.

Not everyone is as experienced or confident as you are, so will potentially take a lot longer to figure out something that is designed to help you help them.

We should also not assume that persons level of education is less than ours, a person with a degree in Computing is equally degree qualified a degree in Chemistry (for example). However both can perform complex tasks. but probably can't perform each others tasks. Education is only a factor in this respect.

For most people, they want something to 'just work' and not have to fiddle to get it working or try to explain what they are doing, which if you are not sure, just ends up frustrating when ask questions you can't understand let alone answer.

So trying to get a device working that requires a user to load kernel modules in, is really beyond a lot of people without the pre-requite understanding, on a similar note, When installing Debian 11 on my netbook I found that networking simply didn't work, or the install didn't complete., in fact upgrading from 10 to 11 seems to break networking fully. So trying to ask for help isn't easy, especially when there is no easy way to tell people what the error is.

In the above case the following would most certainly apply

  • Task a Learner Cannot Accomplish With Assistance

Or in this case they would need face to face assistance and even then the error could be something that a person with expertise can't easily fix.

I am not sure what the solution is, perhaps just to say, please remember, just because you are an expert, doesn't mean others are too.

LibreAdventure is a free software implementation of Work Adventure. This is a 2d environment which you can walk round and interact with other users. This is a Free Software Foundation project, so there is integration with the Jit.si video conferencing software to facilitate voice / video communications.

The graphics (while rather 8bit retro) is what makes this really cool. I am not technical enough to run my own implementation. I am using the FSF instance and testing that.

I think this version gives a 2d top down view of the FSF office, I can enter a conference room, or enter other rooms.

LibreAdventure was used as part of LibrePlanet 2021, and will be used at this years conference too.

Sending life to the stars

Reposting with an update

Interesting article from Science daily on Sending life to the stars. Looks like we are getting closer to being able to propel objects to near to the speed of light.

Granted this research they are looking at 20-30% but this is a big step forward.

Original Mastodon post

Happy do discuss on Mastodon, Discourse or at the Paignton Library STEM Group meetings.

Lots of life which can survive in very harsh conditions.

Smart windows can significantly reduce indoor pathogens

Smart windows can significantly reduce indoor pathogens

Posted to Mastodon.

The researchers found that, compared to windows with blinds, the smart windows significantly reduce bacterial growth rate and their viability. [1]

Comment

An idea / question from this is could this technology be used on space missions to help protect spacecraft from harmful UV radiation but also take advantage of sanitising properties of UV Radiation. As a quick reference, I have put a link to a wikipedia article below, please note: Wikipedia is not an academic source of information the link is there for reference purposes only.

Perhaps discuss at a STEM group meeting or on a forum. Links

Smart soil bugs offer farmers an ecofriendly route to controlling crop diseases

Smart soil bugs offer farmers an ecofriendly route to controlling crop diseases*

So given we have managed without chemicals for 1000's of years, this is going back to what we have done before, only the research will allow us to grow crops better based on science based knowledge of soil composition.

Fediverse Rising

This is a copy of my article sent in to the Beach hut article published January 2022

Fediverse Rising

Former President Donald Trump just launched his own social media network. If the login screen looks familiar, that may be because it has the same look and feel of the social media application Mastodon [1]. But what is Mastodon, and why is it important?

Mastodon is a decentralized social media site. This means that instead of one big site, like Facebook, people can run their own “nodes” and the users on each can share information with the rest of the network. There is no advertising, no data collecting, or tracking, so there is more privacy, although this is not to say public posts can’t be “scraped.”

Mastodon sites are federated and there is no single owner of the whole social media service. You can run your own Mastodon server, called an “instance,” and interact with other users on other instances. These communicate through a protocol called ActivityPub. [2] The network of instances, called the Fediverse, consists of instances running the Mastodon software licensed under the GNU Affero General Public License [3] from the free software foundation [4]. An example of Federation is e-mail, there are different providers of e-mail e.g disroot, protonmail and they can all work together.

Just like on mainstream social media such as Facebook and Twitter, you can share pictures, messages, media, and links and can follow other people or topics (using hasthtags) of interest. A project called Trunk [5] helps you find people who like similar interests.

The Fediverse community values user input. The community on socialhub [6] are keen to build a social network system that is welcoming and safe for everyone, one that everyone can collaborate and work together. Some of this community are communicating with the EU / UK governments to ensure legislation and internet governance is fit for purpose and puts users before profits.

Planets form in organic soups with different ingredients

Interesting article found on Mastodon, scientists have mapped the chemical composition of planetary nurseries. Looks like I have quite a bit of reading to do, as there are 3 papers linked to this article.

I have included the usual links to the original article & discourse discussion.
