News from the blog 2021-10-21

  • I made a Donation to The Document Foundation, which makes the OpenOffice.

I use OpenOffice suite for writing my books and other documents, so I think it’s fair to contribute with their operating costs.

  • I’ve installed a plugin to add Code Highlighting

It also allows me to add blocks of Code, like this:

if CodeHighlighting.b_is_installed == True:
    return VisualImprovement.update_to(10), "It's easy to read"
else:
    return VisualImprovement.get_still_the_same_difficult_to_read(), "The blog lives in the medieval age"

Or Inline Code like print(self.awareness) which is also great

  • I’ve improved a bit, visually, the blog

I modified a bit my template. The changes consist into adding an id attribute to the table for the Quick Selection of the articles, and modifying my template: the styles in the file css/blocks.css and modifying the version in functions.php to reflect the new timestamp.

I also made that when the mouse goes over a link it is displayed in blue, and the already visited in a slightly darker blue.

#articles_selection a:hover {color: #2222FF;}

In the images below you can see the before, the intermediate, and the final.

I’ve also added a button to hide or show the Quick Selection

If you have a WordPress and jQuery does not work for you, with error:

TypeError: $ is not a function

$(document).ready(function(){

This is because for compatibility reasons you have to do different in WordPress:

jQuery(document).ready(function($){
  • I created several videos of 5 minutes to learn Unit Testing in Python 3 with pytest

I also use my package carleslibs to execute the command from shell.

Web CTOP in this case :)

As I did this I discovered a bug (bug #47) in CTOP for setting the number of rows.

  • I fixed the bug #47 and the bug #48 in CTOP and started version 0.8.7 (available in Master).

The changelog.txt file details all the changes for each version.

Here CTOP is displayed with a fixed width and height as by launching with:
ctop.py –rows=50 –columns=170
  • The new PSU arrived and I replaced it on Saturday 16th

After 5 days working nonstop, with no problems, it seems clear that the failing item was the expensive, 850W, Corsair PSU. Sometimes it happens that a new component comes defective, but I paid overprice expecting quality, and it seems that the PSU was defective. Since the beginning the computer powered off every few hours max, so I have to finally assume that effectively it was the PSU. Disappointed with Corsair.

  • Firewall. This month I’ve blocked around 2,000 visitors that were mainly bots searching for exploits

I review the logs several times every day.

Actually I’ve blocked many more Ip’s in the firewall, as when I identify a company source of bots, I block all their range (Imagine, as I block entire class C addresses, there are 256 Ips each class C /24). This has translated into 2,000 visitors less per month to the blog, that were offenders.
