Joerg Jaspert: Electric Car, Vacation trip

Planet Debian - Thu, 2024-08-15 06:12
Electric Car

A while ago I got my hands on an electric car - after not having owned a car for most of my life (there really is not much need here). It wasn’t planned nor a goal of mine, but it kind of “came out of talks with my boss”, so now it’s there.

Due to some special rules in the german tax system it turns out really cheap for me - it comes from the company, which allows personal use. So I have to pay taxes on the value of it plus whichever amount of kilometers I have to drive to work. And the latter is what is good for me - I have homeoffice in my contract, so no drive to work, except maybe once a year for something. So no regular trip to calculate, only if I ever really have to do a trip to the office.

And it being an electric car, running costs are also cheap. Way below the outdated tech that needs gas to run, is annoyingly loud and stinks.

The car

In the past I used either car sharing or renting a car when I needed one, depending on what I actually needed. Last times renting I already tried electric variants, so I could compare this with.

What I have now is a “Citroen e-Berlingo XL” from 2023 (so not the latest change from 2024), which is on the huge size for space, but small for battery. It has 7 seats (though I have the last 2 currently taken out, no daily need) and more storage space than I need even on a vacation trip.

The engine (or well, it’s battery) is on the small side - a capacity of 50 kWh means it only has 278km reach according to WLTP. That actually is a good bit less - as usual, those numbers are lying for the producer. Turns out that on highways in a more realistic mode than WLTP (read: real driving) it’s somewhat around 120km before one wants a charger again. But, looking around, at least in Germany that is not a big problem, there are more than enough chargers available.

Driving

Actually driving experience is good. It sure is a huge car (4.7m long, 1.85m high/wide) and feels more like driving a (small) bus, but it is easy to handle. Maximum speed is limited (or the small battery would suck even more) to 135km/h, but that is more than enough. Even on german highways. Did my vacation trip with cruise control set to 115km/h and very few times only went above that manually. Real relaxed driving that was.

Vacation trip

So we had a vacation just recently, and instead of renting a car for the trip we, of course, wanted to take the e-Berlingo. Distance was about double what the car can (realistically!) do, so one charging stop in the middle somewhere was a must. Not having had to charge on highways yet - and entirely new with this car - that made for a bit of nervousness, but it all turned out really good. There are really nice tools like ABRP to plan your trip including charging, which can take live data of availability of charging points into the planning.

And it turned out nice - we reached our planned charging point and found a long queue of cars waiting. But turns out it was all those poor folks that need actual gasoline for their outdated combustion engines. The charging points for EV cars still had enough free space, so we could bypass the queue and directly start charging. We also did not need to repark the car after just a few minutes, we could directly start our break.

With a charging time of approx. 30 minutes using the fast charger, such a break is long enough to get enough energy for the next part of the trip and short enough to not be annoying.

Charging prices

At home it depends. If one has some photovoltaic system to get power, charging is basically free. If not it depends on whichever contract one has, costs will be somewhat between 0 and ~30cent per kWh. Not much, and way below gasoline costs.

Outside, using a fast charger, prices vary depending on where you charge - and with what charging card. Prices between 40 and 70cent / kWh, and the same charging point can vary, just from the card one uses. That is a thing that the EU could actually go and better regulate, similar to the phone regulations it took. Still, the costs are still way below gasoline.

Charging cards

There is a huge amount of different providers available, and all do their own things in pricing and how one can use them. They do have standards (say, the plugs are standardized, by now the way to start charging also), and that enables roaming (use a charging card of one provider at a charging point of another), but other than that, it seems to be random.

That is - if you use card A on a charging point of Provider B you may pay 0.49cents, if you use card C on the same point, it may charge you 0.79cents. And card D isn’t taken at all. Some (the newer ones) you can pay directly by credit card, many you can’t. Some may allow paypal or Google/Apple Pay. So in the end you need more than just one charging card - I collected 8 free ones by now - just to be sure you can find a combination that isn’t hugely overpriced.

Drupal blog: Drupal CMS: the official name for Drupal Starshot

Planet Drupal - Thu, 2024-08-15 05:57

This blog has been re-posted and edited with permission from Dries Buytaert's blog.

We're excited to announce that "Drupal CMS" will be the official name for the product developed by the Drupal Starshot Initiative.

The name "Drupal CMS" was chosen after user testing with both newcomers and experienced users. This name consistently scored highest across all tested groups, including marketers unfamiliar with Drupal.

Participants appreciated the clarity it brings:

Having the words CMS in the name will make it clear what the product is. People would know that Drupal was a content management system by the nature of its name, rather than having to ask what Drupal is.

I'm a designer familiar with the industry, so the term CMS or content management system is the term or phrase that describes this product most accurately in my opinion. I think it is important to have CMS in the title.

The name "Drupal Starshot" will remain an internal code name until the first release of Drupal CMS, after which it will most likely be retired.

Tag1 Consulting: Migrating Your Data from Drupal 7 to Drupal 10: Preparing for field migrations

Planet Drupal - Wed, 2024-08-14 10:39

Series Overview & ToC | Previous Article | Next Article - coming soon! --- So far we have migrated three entity types: content types, taxonomy vocabularies, and paragraphs. It is very common that fields are attached to those, and other entities, to collect and display data. Field migrations can be tricky. For one, it is a multi-step process that requires, at a minimum, four different migrations. Additionally, it is common to find errors because field related configuration used in Drupal 7 is not available in Drupal 10. In this article, we take a pause from executing migrations to understand how fields work in Drupal. The information presented today will prove useful for custom migrations, especially when they include content model changes. ## Understanding Drupal fields Drupal fields are used to provide structure to the information the CMS stores. They save discrete data, which can be used for displaying, filtering, and sorting purposes. Fields are attached to entities like nodes, users, taxonomy terms, blocks, etc. For entities that can have bundles, each bundle can have a different set of fields attached to them. The node entity, for example, almost always has a different set of fields attached to each content type...

Real Python: The Walrus Operator: Python's Assignment Expressions

Planet Python - Wed, 2024-08-14 10:00

Each new version of Python adds new features to the language. Back when Python 3.8 was released, the biggest change was the addition of assignment expressions. Specifically, the := operator gave you a new syntax for assigning variables in the middle of expressions. This operator is colloquially known as the walrus operator.

This tutorial is an in-depth introduction to the walrus operator. You’ll learn some of the motivations for the syntax update and explore examples where assignment expressions can be useful.

In this tutorial, you’ll learn how to:

  • Identify the walrus operator and understand its meaning
  • Understand use cases for the walrus operator
  • Avoid repetitive code by using the walrus operator
  • Convert between code using the walrus operator and code using other assignment methods
  • Use appropriate style in your assignment expressions

Note that all walrus operator examples in this tutorial require Python 3.8 or later to work.

Get Your Code: Click here to download the free sample code that shows you how to use Python’s walrus operator.

Take the Quiz: Test your knowledge with our interactive “The Walrus Operator: Python's Assignment Expressions” quiz. You’ll receive a score upon completion to help you track your learning progress:

Interactive Quiz

The Walrus Operator: Python's Assignment Expressions

In this quiz, you'll test your understanding of the Python Walrus Operator. This operator was introduced in Python 3.8, and understanding it can help you write more concise and efficient code.

Walrus Operator Fundamentals

First, look at some different terms that programmers use to refer to this new syntax. You’ve already seen a few in this tutorial.

The := operator is officially known as the assignment expression operator. During early discussions, it was dubbed the walrus operator because the := syntax resembles the eyes and tusks of a walrus lying on its side. You may also see the := operator referred to as the colon equals operator. Yet another term used for assignment expressions is named expressions.

Hello, Walrus!

To get a first impression of what assignment expressions are all about, start your REPL and play around with the following code:

Python 1>>> walrus = False 2>>> walrus 3False 4 5>>> (walrus := True) 6True 7>>> walrus 8True Copied!

Line 1 shows a traditional assignment statement where the value False is assigned to walrus. Next, on line 5, you use an assignment expression to assign the value True to walrus. After both lines 1 and 5, you can refer to the assigned values by using the variable name walrus.

You might be wondering why you’re using parentheses on line 5, and you’ll learn why the parentheses are needed later on in this tutorial.

Note: A statement in Python is a unit of code. An expression is a special statement that can be evaluated to some value.

For example, 1 + 2 is an expression that evaluates to the value 3, while number = 1 + 2 is an assignment statement that doesn’t evaluate to a value. Although running the statement number = 1 + 2 doesn’t evaluate to 3, it does assign the value 3 to number.

In Python, you often see simple statements like return statements and import statements, as well as compound statements like if statements and function definitions. These are all statements, not expressions.

There’s a subtle—but important—difference between the two types of assignments with the walrus variable. An assignment expression returns the value, while a traditional assignment doesn’t. You can see this in action when the REPL doesn’t print any value after walrus = False on line 1 but prints out True after the assignment expression on line 5.

You can see another important aspect about walrus operators in this example. Though it might look new, the := operator does not do anything that isn’t possible without it. It only makes certain constructs more convenient and can sometimes communicate the intent of your code more clearly.

Now you have a basic idea of what the := operator is and what it can do. It’s an operator used in assignment expressions, which can return the value being assigned, unlike traditional assignment statements. To get deeper and really learn about the walrus operator, continue reading to see where you should and shouldn’t use it.

Implementation

Like most new features in Python, assignment expressions were introduced through a Python Enhancement Proposal (PEP). PEP 572 describes the motivation for introducing the walrus operator, the details of the syntax, and examples where the := operator can be used to improve your code.

This PEP was originally written by Chris Angelico in February 2018. Following some heated discussion, PEP 572 was accepted by Guido van Rossum in July 2018.

Since then, Guido announced that he was stepping down from his role as benevolent dictator for life (BDFL). Since early 2019, the Python language has been governed by an elected steering council instead.

The walrus operator was implemented by Emily Morehouse, and made available in the first alpha release of Python 3.8.

Python Anywhere: Postal code validation for card payments

Planet Python - Wed, 2024-08-14 07:00
TL;DR

We recently started validating that the postal codes used for paid PythonAnywhere accounts match the ones that people’s banks have on file for the card used. This has led to some confusion, in particular because banks handle postal code validation in a complicated way – charges that fail because of this kind of error can show up in your bank app as a payment that then disappears later, or even as a charge followed by a refund. This blog post is to summarise why that is, so hopefully it will make things a bit less confusing!

The long version…

Card fraud is, sadly, a fact of life on the Internet. If you have a website that accepts payments, eventually someone will try to use a stolen card on it. If your site is online for some time, hackers might even start using you to test lists of stolen cards – that is, they don’t want to use your product in particular, they’re just trying each of the cards to find the ones that are valid, so that they can use them elsewhere.

We recently saw an uptick in the number of these “card probers” (as we call them internally) on PythonAnywhere. We have processes in place to identify them, so that we can refund all payments they get through, and report them as fraudulent to Stripe – our card processor – so that the cards in question are harder for them to use on other sites. But this takes time – time which we would much rather spend on building new features for PythonAnywhere.

Looking into the recent charges, we discovered that many of them were using the wrong postal code when testing the cards. The probers had the numbers, the expiry dates, the CVVs, but not the billing addresses. So we re-introduced something that had been disabled on our Stripe account for some time: postal code validation for payments. You may be wondering why it wasn’t enabled already, or why it might even be something that anyone would disable; this blog post is an introduction to why postal codes and card payments can be more complicated than you might think.

Planet Python - Tue, 2024-08-13 17:41

The new and improved AI Assistant for the 2024.2 versions of JetBrains IDEs is now out, featuring smarter and faster AI code completion for Java, Kotlin, and Python; an enhanced UX when working with code in the editor; AI functionality for Git conflict resolution, in-terminal code generation, new customizable prompts, improved test generation, and more.

Don’t have AI Assistant yet? 

To experience the latest enhancements, simply open a project in your preferred JetBrains IDE version 2024.2, click the AI icon on the right toolbar to initiate the installation, and follow the instructions to enable it. 

You can also experience free local AI completion functionality with full line code completion (FLCC) in your IDE of choice, including CLion and Rider starting from 2024.2. Learn more about FLCC in this blog post. 

Faster and smarter cloud code completion

One of the main focuses of this release was to enhance the user experience of AI code completion in JetBrains IDEs. Here are some of the major advances we’ve made in this direction:

JetBrains code completion models for Python, Java, and Kotlin

We’ve significantly improved the quality and reduced the latency of our code completion for Java, Kotlin, and Python. These enhancements are powered by JetBrains’ internally trained large language models. Enhanced locations for cloud completion invocation extend the variety of usage scenarios, while improved suffix matching ensures that the predicted code snippet correctly completes the existing code.

Syntax highlighting for suggested code

Inline code completion suggestions now come with syntax highlighting, improving the readability of the suggested code.

Incremental acceptance of code suggestions

To simplify the process of reviewing suggestions, multiline code suggestions are now displayed only after accepting a single-line suggestion, allowing you to review and accept code gradually. Additionally, if you don’t want to accept an entire suggested line, you can accept it word by word using the same shortcut that you’d typically use to move the caret to the following word (Ctrl+→ for Windows and ⌥→ for macOS).

Seamless interaction of all available code completion types

We have made UX improvements to better integrate AI code completion features into IDE workflows. This includes a reworked UX for multiline completion and the ability to display suggestions alongside basic IDE completions.

Enhanced in-editor code generation

With the latest update, JetBrains IDEs now feature an improved AI code generation experience. Previously, generated code would open in a new tab. Now, it’s displayed directly in the current editor tab, allowing for an immediate review of the generated content. Check it out using the shortcut ⌘\ on macOS or Ctrl+\ on Windows and Linux.

AI chat becomes smarter GPT-4o support

With the new release, AI Assistant now supports the latest GPT-4o model, bringing a boost to the AI Assistant’s chat-related functionalities, such as finding and explaining errors, explaining code, and refactoring.

Chat references and commands

We have introduced chat references and commands to enhance your AI Assistant’s chat experience, giving you more control over your context. Now, you can reference any symbols, allowing you to quickly indicate the context of your query and get more precise responses. Additionally, you can easily mention specific files or uncommitted local changes. Supported commands include /explain and /refactor, allowing you to quickly get explanations or refactor selected code without typing out questions in the chat.

New feature: merge VCS conflicts with AI

When multiple contributors are making changes to the same part of the codebase, and you try to pull your changes, conflicts may arise. To avoid any issues down the line, JetBrains IDEs now provide a tool for reviewing and resolving any such conflicts. Starting from version 2024.2, the Git conflict resolution modal dialog features AI capabilities to assist with merging conflicts. After AI has done its job, you can review the merged result and either accept everything or revert the changes individually. 

New feature: AI-powered command generation in the new Terminal

Generate commands with AI directly in your IDE via the new Terminal tool window. This integration ensures you can efficiently complete command-line tasks without distraction, improving your overall workflow.

Enhanced unit test generation with AI Assistant

Starting from version 2024.2, the Generate Unit Tests action can be invoked not only on methods but also on classes. If a class has multiple methods, the AI will automatically choose the most suitable one for testing. The latest update also includes more customization options for unit test generation. 

Customizable unit test guidelines

Users can set their own unit test guidelines by customizing the test generation prompt in the AI Assistant’s Prompt Library. This allows you to add specific testing rules for Java, Kotlin, JavaScript, Go, Python, PHP, and Ruby.

Adding test cases to existing tests

AI Assistant now supports adding new test cases to existing test files for Java and Kotlin, allowing you to generate new tests using AI.

Сustom prompts for documentation generation 

The latest update to JetBrains IDEs introduces customizable documentation generation prompts. This feature allows the model to generate documentation for a selected code element and inserts it directly into the code. Users can now define the desired content of the generated documentation for different languages and specify various formatting options, such as Javadoc for Java, ensuring the documentation adheres to preferred styles and standards.

Natural Language setting

You can now specify the language in which you want to interact with the AI chat via Settings. After enabling the Natural Language setting, the context of the current chat will be updated, and any new answers generated by the AI will be provided in the user’s chosen language.

Using AI for working with databases

The new release brings AI to a variety of database-specific features within JetBrains IDEs. You can try these out in DataGrip or in a JetBrains IDE of your choice using the bundled Database Tools and SQL plugin.

Get AI assistance when modifying tables

AI Assistant can now help you change the database-specific parameters of a table. Ask AI Assistant to modify a table according to your requirements right in the Modify dialog. Once AI Assistant generates the requested SQL code, you’ll be able to review it in the preview pane of the dialog and then apply the changes.

Explain and fix SQL problems


DataGrip’s code inspections detect various issues with your SQL queries before execution, which are then categorized according to predefined severity levels.

The latest update integrates AI to enhance the comprehension and resolution of SQL problems. For issues with a severity level higher than Weak warning, the AI Assistant offers explanations and fixes. For better context and more accurate suggestions, you can also attach your database schema.

AI Enterprise: unlocking organizational productivity

Are you looking to maximize productivity at an organizational scale? AI Enterprise runs on premises as part of JetBrains IDE Services, ensuring complete control over data and AI operations within your organization’s infrastructure. It also provides AI usage statistics and reports, offering insights into how AI tools are utilized across your development teams. Learn more about AI Enterprise.

Enhance your writing with Grazie, now included in the AI Pro subscription plan

We’re excited to share that Grazie, our AI writing companion for people in tech, is now included in the AI Pro subscription plan. Use Grazie to transform your thoughts into clear, well-articulated writing, with features like instant proofreading, inline text completion, summarization, translation, rephrasing, and more!

Grazie is now available as a plugin for your JetBrains IDEs and as an extension for browsers. While there is a free version, AI Pro subscribers enjoy full volume access to the entire suite of Grazie’s AI features, which is 500 times greater than the basic volume and replenishes weekly.

Explore AI Assistant and share your feedback

You can learn more about AI Assistant’s key features here. However, the best way to explore its capabilities is by trying it out yourself.

As always, we look forward to hearing your feedback. You can also tell us about your experience via the Share your feedback link in the AI Assistant tool window or by submitting feature requests or bug reports in YouTrack.

Happy developing!

Planet Debian - Tue, 2024-08-13 13:59

Things developed since my last post. Some lesions opened up on my ankle which was initially good news: the pain substantially reduced. But they didn’t heal fast enough and so medics decided on surgical debridement. That was last night. It seemed to be successful and I’m in recovery from surgery as I write. It’s hard to predict the near-future, a lot depends on how well and fast I heal.

I’ve got a negative-pressure dressing on it, which is incredible: a constantly maintained suction to aid in debridement and healing. Modern medicine feels like a sci fi novel.

Stefanie Molin: How Pre-Commit Works

Planet Python - Tue, 2024-08-13 09:51
So, you've just set up pre-commit hooks on your repository using `pre-commit`, but do you know what actually happened when you ran `pre-commit install` or why you had to run it in the first place? How does `pre-commit` actually work with Git? In this article, I will take you behind the scenes of how your `pre-commit` setup works.

Bad information drives out good or how much can we trust Wikipedia?

Planet KDE - Tue, 2024-08-13 04:29

This post is written on behalf of the LabPlot team. It’s different compared to what we usually publish on our homepage but we feel we need to share this story with our community.

Introduction

You might already know this, but finalizing a release for a project with the complexity and scope like that of LabPlot can be hard and exhausting. After our latest recent 2.11 release, we decided to take a short break and distance ourselves from coding and take care of other non-coding related tasks, like discussions around the NLnet grant for LabPlot, our ongoing GSoC projects, the roadmap for the next release, improving our documentation, the gallery on the homepage and the article about LabPlot on Wikipedia. Don’t worry, we’re already back to coding and working on new features for the next release

The article about LabPlot on Wikipedia (we are talking about the ‘EN’ version here, but the situation is similar for other languages) was completely outdated and still containing the information about LabPlot1 from Qt3/KDE3 times. The article became largely wrong with the introduction of LabPlot2 and with further developments in recent years. Among other things, the feature set described on Wikipedia was very far from being correct and complete in comparison to the description for other applications of its type.

The current situation was clear for us and it was also evident what needed to be done. Let’s go ahead and improve the article, we thought. Hey! Being able to contribute and to share your knowledge with everybody is the advantage of Wikipedia, right? Easier said than done…

Key Takeaways

But before we begin:

  • Wikipedia itself points out that the purpose of Wikipedia is to benefit readers by acting as a comprehensive compendium that contains information on all branches of knowledge. For this purpose, as it is clearly stated on Wikipedia, “Wikipedia has many policies or what many consider “rules”. Instead of following every rule, it is acceptable to use common sense as you go about editing. Being too wrapped up in rules can cause a loss of perspective, so there are times when it is better to ignore a rule. Even if a contribution “violates” the precise wording of a rule, it might still be a good contribution.” Link: Use common sense.
  • According to Wikipedia there is no need to read any policy or guideline pages to start editing. The five pillars of Wikipedia are a popular summary of the most important principles. And the three of the pillars are formulated as follows: 1. Wikipedia is free content that anyone can use, edit, and distribute. 2. Wikipedia’s editors should treat each other with respect and civility. 3. Wikipedia has no firm rules. And If a rule prevents you from improving or maintaining Wikipedia, ignore it.
  • In this Wikipedia’s article on https://en.wikipedia.org/wiki/Wikipedia:Dispute_resolution it is stated that once sustained discussion begins, productively participating in it is a priority. Editors should focus on article content during discussions; comment on content, not the contributor. And when an editor finds a passage in an article that is biased, inaccurate, or unsourced the best practice is to improve it rather than deleting salvageable text.
  • I fully acknowledge these common-sense principles. I accept the fact that some phrases of the original version of the new content added by Dariusz, another core member of the LabPlot team, might have possibly infringed a less general rule on Wikipedia, and that’s why he asked for a constructive assistance, to no effect.
  • I can also accept the reality and the existence of different users with the various amount of expertise, goodwill and power. The worst case are people contributing in a subversive manner over long time to such an open project to achieve more power and authority and completely different and evil goals later, and this can also be related to users with granted power. See the recent XZ Utils backdoor. I also accept the fact that the amount of work behind the scenes on Wikipedia requires the usage of automated mechanisms and bots (“Meet the ‘bots’ that edit Wikipedia”).
  • However, I cannot accept the fact that the quality of knowledge on Wikipedia can be seriously undermined by power users heavily using algorithms and blindly enforcing some subjectively selected, narrow rules against the general principles outlined above, and at the same time not being open to any constructive discussion. The fact that complete content and comments are censored and removed by users with granted power or by their (semi-)automated tools, which deceives the reader and distorts the history of the discussion, is definitely not acceptable. And this is apparently not an exception, see the links here, here and here and many other similar discussions on the internet.

Keep the above in mind while you read what happened.

The incident I want to share with you is certainly not about LabPlot and its team. It’s about the negative impact of blindly invoking algorithms or quoting a single rule by Wikipedia’s users with granted power on the overall quality of the information stored on Wikipedia. As Dariusz noticed, in economics there is the observation that “bad money” drives out the “good money” from the market (Gresham’s Law “bad money drives out good”). We wonder whether the actions of the entities like MrOllie, some of which are described in the next parts of the article, are enough to justify the introduction of a new law for Wikipedia “bad information drives out good”?

Chain of events

In order to make the content correct and to provide an up-to-date description of the project, similar to the articles for other projects mentioned e.g. on https://en.wikipedia.org/wiki/List_of_information_graphics_software, Dariusz did multiple edits of the article over the course of two days using his Wikipedia account ‘Dlaska’. Very soon after that, the entity MrOllie became aware of his changes and reverted them completely with the suggestion that it was a promotional rewrite. Then, a “user talk” with Dariusz was initiated by MrOllie:

We are all volunteers, having no benefit other than satisfaction from developing LabPlot. But sticking to the principle of intellectual honesty, Dariusz himself fully disclosed to MrOllie that he is a LabPlot team member that felt obliged to step in to correct misleading information in the article and to make the content more complete and up-to-date, because no one has done it for a long time. Unable to get any suggestions from MrOllie despite Dariusz’ requests, Dariusz removed any phrases that could even potentially have promotional qualities (e.g. rename “strongly support” to “support”). Unfortunately, even this had no effect on the actions of MrOllie, resulting in the revert of the new content.

In parallel, I joined these activities and reverted the revert done by MrOllie and provided some explanations for this step. Another “user talk” with me (I don’t have any account, you see my IP address here) was initiated by MrOllie:

After multiple back-and-forth reverts, my IP was blocked and a “Conflict of Interest on the Noticeboard” was raised by MrOllie where he quickly got the support from his peers on Wikipedia. Dariusz’ comment didn’t change anything in the overall situation:

In parallel, more seasoned Wikipedia users jumped on the bandwagon and started ‘editing’ the article by first blindly reverting the article to the version containing potentially promotional content and then removing even more and more content and references with arguments that, in our perception, didn’t make sense arguing with anymore. Any discussion seemed completely ineffective. After most of the content had been removed from the article, to the point that the new version was more deprived of content than the old version, the user Smartse added a notability tag which was later turned into a notification box to the article stating this article “may not meet Wikipedia’s general notability guideline.”. Notability is a test used by editors to decide whether a given topic warrants its own article. So in our perception this could be interpreted as a threat of removing the article completely. The size and severity of the problem we were confronted with was already obvious at this point.

After my IP was unblocked (or maybe because I just got a new IP from my ISP), I was able to reply on this noticeboard. Since I was already foreseeing it’s going to be deleted, I took a screenshot (this is also the reason why I did screenshots for all other events):

Practically immediately my reply, red-highlighted above, was deleted without any comment or note and this is how this thread looks like afterwards:

Fortunately, Dariusz, who has an account in Wikipedia, got the notification about my added reply via email:

and after clicking within seconds on the link in the email he was informed that the comment might have been deleted, and it sure was, right after it had been added.

Immediately after this, another notification box with “A major contributor to this article appears to have a close connection with its subject.” was added to the article:

and my new IP was blocked for “abusing multiple accounts” and using them for “illegitimate reasons”:

After all these deletions, see the full history of changes

This is how the article looks like in its “final version”:

In retrospect

What seems to have happened here looks like a well coordinated or even (semi-) automated chain of events with a pre-defined replies, arguments and actions. MrOllie stands out for the incredible diligence and regularity of his activity. The chart below shows the number of edits he has made by day of the week and hour (in local time), from 2008 to the present (source of the chart: https://xtools.wmcloud.org):

Also, over 75% of MrOllie’s edits are done in a semi-automated way with the help of tools on Wikipedia like Twinkle. So, this account functions like a programmed algorithm or somebody who is heavily relying on them.

Seeing no reasonable chance of correcting this situation in the context of being deprived of the right to effectively discuss the matters with entities like MrOllie, we gave up on our initial idea to improve the article.

What’s next?

After reading more on this subject we realized that this problem is not new, but apparently it is not common knowledge either. Completely independent of who or what censored us – AI bots (is AI already winning over us?), good or bad editors etc. – trusting Wikipedia now is much harder than before. Still, the question remains about what to do next.

We can completely give up the idea of contributing to this platform and rather focus on other channels like our homepage and other online resources in the KDE and free world (Mastodon, etc) and provide more and more useful information.

Alternatively, we can ask for support from other people with more experience in editing and maybe even with more authority on Wikipedia to help us to get a reasonable description of the project on Wikipedia to the benefit of Wikipedia’s readers and LabPlot’s users.

Thoughts?

Links

For the sake of completeness and of easier usage, here are the links mentioned in my reply that were deleted:

Note, for the first two links above, the original posts in the Wikipedia related channels on Reddit about the same MrOllie account on Wikipedia were deleted, shame on those who think evil of this. The comments are still available, though, and the reader can get at least an idea about the original content of those posts.

I want to thank you Dariusz for his contributions to this article.

LN Webworks: Integrating Drupal And Tailwind CSS: Step-By-Step Guide

Planet Drupal - Tue, 2024-08-13 03:31

It’s hectic and time-consuming when it comes to making something that takes a long time. Yes, we are talking about CSS stylesheets. It’s not easy to design a website because it’s not ‘effortless’. 

In this blog, we will talk about the Integration of Drupal and Tailwood CSS to make this process a little bit easier for you. 

A brief About Tailwind CSS

Tailwind CSS adopts a utility-first approach rather than building a class for the component. Tailwind CSS is a utility-first approach that makes creating applications faster and easier

Tailwind CSS offers limited benefits but assures you the flexibility and power to create your unique site.
