In an effort to help people keep kids occupied over the CoronaVirus (Covid-19) crisis.
A few months ago I made a few scratch 3 activities, these have been shared on ScratchEd but given the current circumstances, I am going to share here.
Instructions for each are below
#scratch, #education, #school, #homeschool, #activities, #covid19
In an effort to help people keep kids occupied over the CoronaVirus (Covid-19) crisis.
Now that I have fixed my browser issue. See earlier post. I am going to share some Scratch projects.
Firstly another spiral / pattern making project.
It isn't perfect, but it doesn't need to be. What people can hopefully do, is make it better, which is how we learn.
This project can be found on the Scratch website here.

As I am no longer able to run code club at the library. The frustration with the poor performance of Chromium browser on Debian has prompted me to install Chrome browser.
After a quick search I found a how_to which is easy to follow and Chrome is now fully installed and working.
Performance is now vastly better. I am not sure what is causing the issue on Debian. It needs investigating properly.

UK Corona Virus Lockdown
PM Boris Johnson made an announcement this evening essentially putting the UK on lockdown. Can only go out for work, or shopping for essentials.
From the bbc website.
Here are the major points of his speech:
From tonight, people in Britain will be allowed to leave their homes for only “very limited purposes” - shopping for basic necessities; for one form of exercise a day; for any medical need; and to travel to and from work when “absolutely necessary”
People are warned not to meet friends or family members who they do not live with
Shopping is only permitted for essentials like food and medicine, and people are advised to do it “as little as you can”
Police have powers to enforce the rules, including through fines and dispersing gatherings
All shops selling non-essential goods, such as clothing and electronic stores, are ordered to close
Libraries, playgrounds, outdoor gyms and places of worship are to close
All gatherings of more than two people in public - excluding people you live with - are banned
All social events, including weddings and baptisms are banned
Funerals are not included in the new restrictions
Parks will remain open for exercise but gatherings will be dispersed
Restrictions “under constant review” and will be checked again in three weeks. They will be relaxed “if the evidence shows we are able to”
Determine graphics file resolution.
Just making a quick post to cover something I found earlier. Chatting to a user in #latex on Freenode about inserting pictures in to $\LaTeX$ documents. It seems scaling the image isn't an issue as long as you know the actual picture resolution.
gives the following example on how to insert a picture in to a $\LaTeX$ document
\documentclass{article}
\usepackage{graphicx}
\begin{document}
\includegraphics[width=\textwidth]{YOUR-FILE-NAME-HERE}
\end{document}
We can reduce this slightly by removing the \textwidth element
\documentclass{article}
\usepackage{graphicx}
\begin{document}
\includegraphics[width=0.5]{YOUR-FILE-NAME-HERE}
\end{document}
Which will scale the image and insert at ½ the width.
In overleaf and on a GUI it is easy to obtain the image properties.
If you're at the cli, and therefore not able to do this, what do you do then.
There are several solutions
gm identify file.png will return some information including the file resolution:
gm identify hexchatSASL.png
hexchatSASL.png PNG 432x549+0+0 DirectClass 8-bit 45.2Ki 0.000u 0m:0.000003s
So on a similar note the file command does something similar
file hexchatSASL.png
hexchatSASL.png: PNG image data, 432 x 549, 8-bit/color RGB, non-interlaced
You can also use the view command, which is part of midnightcommander, so opens up a graphical application to display image data.
Once you have determined the file resolution you can calculate how much you need to scale the image.
If you had an image at say 640x480 (w x h) then and you want to display this at ½ the width. Then you can insert
\includegraphics[width=0.5]{YOUR-FILE-NAME-HERE}
To calculate the displayed size you can use
$0.5 \times 640 = 320$
So in this example your image will display, with a width of 320 pixels in your document.
If you use 0.75 then the width is going to be 480
$0.75 \times 640 = 480$
Hopefully this will help someone out there. I did something useful while helping with this.
