CONTINUAL INTEGRATION

One of the below problem scenarios is happening.

Possible problem scenario #1
You try to download a file with curl or wget. Instead of downloading the file, you get a file with this as the content:

gzip: /home/ubuntu/foobar.tar.gz: not in gzip format
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

You use a web browser, and you can download the file. You know the website works perfectly. Why cannot you download the file on a Linux machine (using the character prompt)?

Possible problem scenario #2
You run curl or wget, and you see that you are being redirected. What flag should you use with curl to get it to work?

Possible problem scenario #3
You try to run a curl command, but you get this error message:
curl: (3) URL using bad/illegal format or missing URL

Solution
Use a command like this:

curl -L https://www.continualintegration.com/foobar.tar.gz --output /tmp/foobar.tar.gz

# Replace https://www.continualintegration.com/foobar.tar.gz with the URL you are downloading the .tar.gz file from
# Replace /tmp/foobar.tar.gz with the destination location and desired name of the file you are downloading

Problem scenario
You want to copy a subarea of a copied screenshot (just like Paint in Windows). How do you copy a rectangle cropped selection of a pasted screen shot using LibreOffice Draw?

Solution
1. Open LibreOffice Draw and paste the image in.
2. Click on the square icon in the upper right. It is an image of a square with sides extended on the left upper and right lower corners like this:

Click that beige/orange square with an empty middle.

Now you can select a subimage by moving a blue symbol on the perimeter inward.

Problem scenario
You have red about gel wrist pads for keyboard and mouse utilization. You think you should invest in ergonomic equipment. Should you get a wrist rest for your computer usage?

Solution
It is not clear.

For the "Yes":
Many companies that sell them recommend them, and some people prefer the gel support.
This site says to use them.

For the No:
This site says to not use wrist rests.

Another site says that it did not help one person who tried it.
