Effect of long term space flight on the Brain

Study explores effects of extended spaceflight on brain

Scientists from the U.S., Europe and Russia are part of a team releasing the results of a large collaborative study involving the effects of long duration spaceflight on the brain.

Positive note: Despite the current situation in Ukraine, those involved in science can still carry on working and collaborating, for the benefit of everyone.

Hubble from Space and Integral-field Spectroscopy

*Hubble from Space and Integral-field Spectroscopy from the Ground: Seeing Both the Forests and the Trees

This is the Space Telescope Science Institute Lecture from March 2022.

A detailed, but also beginner friendly, in parts, introduction to spectroscopy also looking how this is applied and used in Astronomy.

Lots of work behind the scenes to iron out some bugs & problems with the software. I was involved with further testing on 15/3 and there is further testing planned for 17/3. This testing has also included load testing so we know the server will stand up to the number of users expected.

Looking good for the weekend. There will be a LibrePlanet post on Saturday with a link to this.

Github Co-pilot discussion

Copilot is a AI tool to help developers with writing code. There will be a discussion on Thursday 3rd March and Monday 7th March to discuss various issues arising from the use of this.

More information can be found in the FSF article

This will take place on IRC Libera Chat at 19:00 UK time.

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.
