Open Street map 5

So, further to my previous post, I have now made further edits to the map. STEAM Café and Music shop next door are now added, I am trying to change Peacocks, which is listed as a vacant building to the map. I need to add it as a clothes shop or shop, but can't find in the list, so have asked on Matrix for help.

I have also suggested on the UK community forum that we can perhaps use the Tinkerers meetings to meet up with other OSM hackers. It just needs something to start this off, then a group can be formed, and a more formal schedule can be agreed upon.

There are now some OSM flyers in the STEAM Café,
You should be able to tag me on OSM/Forum and Matrix with @zleap

If you are a local business, then it is in your interest to be on the map accurately, as the OSM data can be used as part of Apps that point to local information, keeping the map updated is really vital.

Bash scripting 16 – Using data files 2

So, carrying on from the previous article(s). I am going to be using gnuplot and awk, and see what I can do with the data generated by my script.

It would be useful to be able to remove content in the file we are using with awk, so new data is not added to existing data.

We can do this by running:-

echo " " > log.csv

This should ensure the file is empty

we can then rerun

./gencsv1.sh 

And check contents with

echo csv.log

So according to the article, we can list the data in the 2nd column

awk -F, '{ print $2}' log.csv

 2
 7
 14
 4
 5
 7
 17
 19
 0
 19

and on a similar note, to list what is in the first column

awk -F, '{ print $1}' log.csv

and we can calculate the sum using

awk -F, '{ sum +=$2} END { print sum }' log.csv
94

and the average

awk -F, '{ sum +=$2} END { print sum/NR }' log.csv
8.54545

Chat

I am on the Devon and Cornwall Linux user group mailing list and also their matrix channel as zleap, it is better to ask there, that way others can answer too.

Bash scripting 15 – Using data files 1

So, carrying on from the previous article. I am going to be using gnuplot and awk, and see what I can do with the data generated by my script.

So the first task, if of course to install gnu plot

sudo apt install gnuplot

It is also a good idea at this stage to determine version numbers of the tools we are using

gnuplot -V
gnuplot 6.0 patchlevel 0

and

awk -V

Windows Recall

• Microsoft are bringing back their Recall feature

There are serious security and privacy concerns about this feature, and even if you opt out of it, it does not mean your data is safe.

Time to switch to replacement operating systems and start to learn them. Don't forget also that Windows 10 support ends in August. You may be forced to upgrade to Windows 11 on your hardware, or depending on when you bought the computer, upgrade the whole computer with a new one just so you can run Windows 11.

Bash scripting 14 – Generating data files

Issue 249, May 2025 of Linux Magazine, p52-55, had an article on using awk, and gnu plot to manipulate data. In order to try and make use of this, and learn more, I am trying to figure out how to write a csv file.

Write 10 lines to the first column should be in sequence e.g. 1-10 and the 2nd column should be random numbers. This should be written to a file.

So after some digging I managed to come up with this, by modifying some existing solutions

write_csv(){
    echo \"$1\",\"$2\" > log.csv # write to file, use >> to append
}

#sources of help
echo "number" "data" # for reference, not written to file 
for ((i = 0 ; i < 10 ; i++)); do
    echo $i, $RANDOM # echo to screen (stdout)
	echo $i, $RANDOM >> log.csv # write to file
    #write_csv $(($i, $RANDOM % 10))
done

The screen output for me was

number data
0, 17109
1, 2872
2, 22572
3, 7228
4, 27923
5, 6335
6, 20004
7, 32343
8, 10005
9, 21905

While the file output (log.csv) was similar but without the headings, which I just put in for my own reference, the file does work as a csv as I can open in LibreOffice Calc.

0, 17109
1, 2872
2, 22572
3, 7228
4, 27923
5, 6335
6, 20004
7, 32343
8, 10005
9, 21905

As the numbers are quite big, a closer examination, promoted me to make the following modification

echo $i, $((RANDOM % 20)) # echo to screen (stdout)
echo $i, $((RANDOM % 20)) >> log.csv # write to file

This fixes the 2nd column to produce a number between 1 and 20.

number data
0, 17
1, 12
2, 12
3, 16
4, 2
5, 13
6, 10
7, 6
8, 16
9, 16
cat log.csv
0, 3
1, 17
2, 8
3, 16
4, 10
5, 18
6, 5
7, 14
8, 11
9, 11

The script was called gencsv1.sh, which as expected needed execute permissions

chmod +x gencsv.sh

Top 10 skills in demand 2025

There are numerous sites with this or similar information on what are the most in demand skills of 2025.

Some of my recent posts point to courses or information on these areas. Others will require your own research [2]. This list is from True Digital Academy [1].

1. Data Science & Cloud Computing
2. Artificial Intelligence (AI) & Machine learning (ML)
3. Big Data
4. Digital Marketing and strategy
5. Process Automation
6. Business Development
7. Digital Transformation
8. Information Security and Cybersecurity
9. Software and Application development
10. Internet of things

I made a post a few years ago, with a link to training courses from the Linux Foundation and others [3]. So there are some links that are related to the above list.

YouTube removes 'gender identity' from hate speech policy

Why are you using platforms such as Youtube? By using Youtube you are using a platform that clearly does not support equality, diversity and inclusion in order to please the US government.

SCOOP: YouTube removes 'gender identity' from hate speech policy. “YouTube quietly removing ‘gender identity and expression’ from its list of protected groups is a major radical shift away from best practices in the field of trust and safety.”
