Using invidious

Invidious is a front end to Youtube that strips out tracking and other 'unwanted' and 'unnecessary' features that impact on user privacy. To use the invidious front end you first need the Youtube video URL for example:

https://www.youtube.com/watch?v=2Is8nZeJNiI

You need to add the latter part in this case :– watch?v=2Is8nZeJNiI to the end of the invidious url

https://invidious.xyz/

So you end up with:

https://invidious.xyz/watch?v=2Is8nZeJNiI

Spacefarers: How Humans Will Settle the Moon, Mars, and Beyond : Writeup

6th April

Speaker: Christopher Wanjek Description: More than 50 years after the Apollo 11 moon landing, why is there so little human presence in space? Will we ever reach Mars? What will it take to become a multi-planet species, colonizing the Solar System and travelling to other stars?

With details here

Write up.

This was another really interesting, thought provoking lecture presented by Christopher Wanjek

The lecture started at about 15:30 in to the video after Frank has given his introduction, details of upcoming lectures and also an update on space news.

So some of the items covered were the cost and difficulty of getting off Earth in to space, then on to the Moon, very expensive. However once there, we are not out of the woods, the lunar surface is bombarded with radiation, the moon dust itself is toxic, growing food would need to be undertaken under artificial light, due to the radiation.

As the temperature on the moon can fluctuate between -200 and +200 F then one course of action for establishing some sort of presence on the moon would be the poles, where the temperature is a “cold, but workable” -50c.

We can harvest ice to produce Water, which can also be converted in to Hydrogen and Oxygen,

Christopher also then looked at how we can develop science on the Moon, Geology, Biology.

A look at gravity and how much humans rely on Gravity and how this can perhaps be created artificially.

The European Space Agency are looking at sending pods to the moon, build something before we go, I think it was also suggested we need to cover any buildings with moon dust, in order to provide full shielding from radiation. This apparently needs to be about 1 meter thick layer. Bare in mind that the dust is like Asbestos. Getting around and some transportation systems were suggested.

We may need to live in caves as these would be a constant temperature and a shield against radiation.

Space tourism could potentially be a huge industry As We are unable to have children on the Moon (something to do with gravity) then building cities may not be practical.

So on to Mars

Firstly getting there is dangerous, we are potentially exposed to radiation over a long period of time, once there the surface is still bombarded with radiation and there are dust storms to contend with, However it was suggested we could live in caves

One way of protecting us from radiation is to use Boron Nitriade, as boron can absorb secondary particles .

Mars surface has toxic components, so we may have to grow food under LED lights.

So lots to think about, lots of challenges a head so a great time to discuss more, study science and help work on the solutions needed.

A lot more was discussed including design of space suits,

Thank you for reading, worth checking out the video and the book Spacefarers by Christopher.

Adapt Learning Suite

As part of the Debian Academy [1], we are currently using Moodle [2] and also Adapt [3] to help create courses. So far I have just had a look at this, but I have found a training guide [4] and was sent a YouTube [5] by David B. So should, with help be able to come up with some ideas for courses.

The idea of Debian Academy, is to help more people in to contributing to Debian, by introducing how to get involved, from packaging, testing. bug reporting and mentoring and much more.

If you are interested in joining please e-mail the team from the Wiki page [1] or join us on IRC – #debian-academy on oftc [6]

EP 4

So this week, Aral and Laura looked at how they live stream their episodes.

Laura talked about accessibility, using subtitles, transcripts and the various tools available to help with that.

Aral then talked about the different hardware / software used for live streaming, mixing video, etc. If you are interested in live streaming video then it is really worth watching for that,

Annotating pdf files PDF files are really useful for moving documents around when you 'need' the recipient to be able to open in a pdf reader and see what you intended.

Unless you have access to expensive software you are usually not able to edit these files easily. While LibreOffice draw can perhaps do this, it may not be ideal for the job.

Xournal [1] is a Debian application, that while mostly aimed at touch screens, is able to annotate pdf files as the video below demonstrates.

As mentioned in the video notes, Xournal will export as a .pdf.pdf file, so you may want to rename it when saving. This is not even an issue for me.

Happy to discuss further on Mastodon [2] or on IRC. Please see contact page for details.

What is Peertube?

Peertube is a video sharing platform, similar to youtube, but with a focus on privacy and decentralization. As Peertube uses Activity pub then content can be shared and federated to other services within the Fediverse.

The video below provides a good explanation of what Peertube is.

Feel free to get in touch if you need more help on this, details are on my contact page.
