I released my Python Open Source libraries for rapid application development: carleslibs to v. 1.0.3.
I updated the page of my 2013 PHP Framework Catalonia Framework, linking to the blog. This is a very nice and lightweight PHP Framework that I created then and it worked so well that I had not the need to update it since 2014.
Donations
Blizzard offered to the employees the opportunity to donate in the name of Blizzard, up to USD $100. It has not been the first time, is a regular thing. Also in the past the company matched any donation we employees did, to help diversity will less resources to study in the university.
I chose to donate to Lions in Cork, Ireland.
When they lived, my grand parents were members and donors from Lion’s in Catalonia, so I trust them.
Security
Log4j Java vulnerability
A critical vulnerability named Log4Shell was found in Apache Log4j Java Open Source logging Library.
Equitas Health helps thousands of HIV-positive in Ohio, Dayton and Columbus.
Thousands more are reached with our prevention, testing, and other services. We are excited about embracing our expanded mission as a strategic step to further that legacy and its reach by providing care for all – with a focus on a safe and open space and highest quality healthcare for the LGBTQ community and others who are medically underserved.
I did my donation following a post by Terra Field, a former colleague at Blizzard and later leading Netflix’s Trans *ERG, but I didn’t see that she organized a gofund campaign, so I donated again :)
As I saw that there is a lack of clarity in the articles about this theme.
I also provided two alternatives ways, one pure Python3 and the other Bash based (grep awk tr)
Books
The books I publish in LeanPub have two prices, the suggested price, which is the price I consider the right price for the book, and the minimum price, which is the minimum price I authorized a reader can pay to have it.
You can buy it for the minimum price. You know better than anyone your economy.
So when a reader buys one of my books for the suggested price, instead of the minimum price, it’s really showing how they appreciate may work.
So thanks for all the support and appreciation you show!. :)
One of the motives I chose Leanpub platform is because I think is fair. No DRM, no BS. And the reader can ask for a refund within 45 days if they don’t like the book. It also makes very happy seeing that I don’t have any refunds. I appreciate it as a token of the usefulness of my work. Thanks. :)
Updates to Docker Combat File book (v.16 2021-11-24)
I added a nice trick to reverse engineering the original Dockerfile from a running Image.
I also added another typical copy and paste error into the Troubleshoot section.
Automating and Provisioning Amazon AWS (EC2, EBS, S3, CloudWatch) with boto3 (Amazon’s SDK for Python 3) and Python 3 book
I’m writing a book about how to automate your Amazon AWS tasks using Amazon’s AWS Python 3 SDK boto3, provisioning new instances, stopping, starting, creating volumes, creating/deleting buckets in S3, uploading/downloading files from S3…
It is currently 20% completed. With 43 pages it shows EC2 section already.
I’ve working in carleslibs v.1.0.3. I added MenuUtils class, which allows to assemble menus super quickly, that execute the code referenced in the menu array. Ideal for building CLI applications very fast.
I also added KeyboardUtils class, which allows to ask the user for String within certain lengths allowing or not spaces and/or underscores, and ask user for Integer values within a certain min and max, having 0 for go back.
The plan is to release the new version of carleslibs as soon as I’ve tested it properly.
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
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.
I added some rules / guidelines to the Leave a Reply section
I moderate all the comments to keep the blog an useful and healthy place.
And I don’t publish Spam, or Marketing messages.
Abusive comments are blocked. Competent Engineers and nice human beings share their points and doubts with data, with technical arguments, with education, in a respectful and polite way. People that cannot observe a minimum decoration are not welcome.
However the 12 Gbps SAS SSD were returning Checksum errors in ZFS when I did copy information or I ran scrub. I’m afraid the enclosure can only provide 6 Gbps at max, or a poor connection. Cables or expanders use to be the reason. I ordered new cables to make a direct connection to the HBA Controller without the enclosure to validate my theory and the drives stopped showing errors.
There is something good in all bad: I have been able to document and explain how to troubleshoot, actual errors in ZFS, in my book and talk about the problems with the cables, and the advantages of using a SAS controller even if you use SATA drives.
I got my first Excellent in an Assignment in an Ireland university, which makes me specially happy. And I keep going on studying in Linux Academy, the last course I did was GCP and Terraform, even if I knew both it helps me to keep my skills sharp.
I share with you some offers and charity bundles that I enrolled and enjoyed a lot:
There is an offer with Microsoft Pass which is that we can use Disney+ for free during 30 days.
I started watching the Mandalorian, Season 2, and is wonderfully displayed in 4K. The quality of the video surprised me. Not that many contents in Netflix are 4K and I really enjoyed the great quality of the image.
Humble Bundle offers a pack of 8 VR games per €13.45. If you like Virtual Reality and have your headset, this pack is amazing, and the benefits go to charity: Movember. The games are downloaded from Steam and the pack will last for 14 days.
Don’t forget to balance how much of your contribution goes to every player.
Unfortunately by default most of the money goes to O’Reilly and Humble Tip and few to the Charity cause. You can change that from the web when going to to the payment.
