Happy 28th Birthday KDE!

Sorry my blog updates have been MIA. Let me tell you a story…

As some of you know, 3 months ago I was in a no fault car accident. Thankfully, the only injury was I ended up with a broken arm. ER sends me home in a sling and tells me it was a clean break and it will mend itself in no time. After a week of excruciating pain I went to my follow up doctor appointment, and with my x-rays in hand, the doc tells me it was far from a clean break and needs surgery. So after a week of my shattered bone scraping my nerves and causing pain I have never felt before, I finally go in for surgery! They put in a metal plate with screws to hold the bone in place so it can properly heal. The nerve pain was gone, so I thought I was on the mend. Some time goes by and the swelling still has not subsided, the doctors are not as concerned about this as I am, so I carry on until it becomes really inflamed and developed fever blisters. After no success in reaching the doctors office my husband borrows the neighbors car and rushes me to the ER. Good thing too, I had an infection. So after a 5 day stay in the hospital, they sent us home loaded with antibiotics and trained my husband in wound packing. We did everything right, kept the place immaculate, followed orders with the wound care, took my antibiotics, yet when they ran out there was still no sign of relief, or healing. Went to doctors and they gave me another month supply of antibiotics. Two days after my final dose my arm becomes inflamed again and with extra spectacular levels of pain to go with it. I call the doctor office… They said to come in on my appointment day ( 4 days away ). I asked, “You aren’t concerned with this inflammation?”, to which they replied, “No.”. Ok, maybe I am over reacting and it’s all in my head, I can power through 4 more days. The following morning my husband observed fever blisters and the wound site was clearly not right, so once again off we go to the ER. Well… thankfully we did. I was in Sepsis and could have died… After deliberating with the doctor on the course of action for treatment, the doctor accepted our plea to remove the plate, rather than tighten screws and have me drive 100 miles to hospital everyday for iv antibiotics (Umm I don’t have a car!?) So after another 4 day stay I am released into the world, alive and well. I am happy to report, the swelling is almost gone, the pain is minimal, and I am finally healing nicely. I am still in a sling and I have to be super careful and my arm was not fully knitted. So with that I am bummed to say, no traveling for me, no Ubuntu Summit

I still need help with that car, if it weren’t for our neighbor, this story would have ended much differently.

• Brief description:
  • Have you ever wanted an interactive calendar to display your Drupal events with drag-and-drop rescheduling, and without using jQuery? There’s a module for that.
• Module name/project name:
  • FullCalendar
• Brief history
  • How old: created in Sep 2010 by ablondeau, though I’ve been behind the most recent releases
  • Versions available: 7.x-2.0 and 3.0.0-beta2 versions available, the latter of which supports Drupal 10 and 11
• Maintainership
  • Actively maintained, latest release was this morning
  • Security coverage, though technically the 3.0.x branch will have it once it’s stable
  • Test coverage, minimal but on the roadmap
  • Documentation - does have a user guide, but created for the D7 version, so newer documentation is needed
  • Number of open issues: 337 open issues, none of which are bugs against the 3.0.x branch
• Usage stats:
  • 3,388 sites, though the vast majority of those are for the D7 version, since the 3.0.x branch is very new
• Module features and usage
  • No jQuery!
  • Lots of configurability plus some extras specifically for Drupal
    • Drag-and-drop to alter events
    • Option to require confirmation
    • Can display toast-style notifications when updates are save
    • Double-click on a day or time to create an event at that time
    • Can display events from different content types, even if they use different fields to store dates, and yes, even different kinds of fields, so a mixture of core and Smart Date fields will work
    • You can set default colors and output type (block or the newer, list-item display), and the ability to override color based on content type or a taxonomy reference
  • This module had been essentially dormant for over 4 years, but I decided to work with Jürgen Haas on reviving it after a similar and popular project called Fullcalendar View was not only marked as “Minimally maintained” and “Maintenance fixes only”, but the project page directed users to contact the maintainer to pay for a premium version, in order to use the current version of the Fullcalendar JS library, or to load events via AJAX, which as been an often-requested feature because Fullcalendar View has had common reports of performance problems on sites with lots of event data.
  • Worse, the maintainer has closed as “won’t fix” issues that had community-provided patches, because he only wanted to provide said improvements in the paid, premium version
  • In my work on the Events recipe for Drupal CMS, I knew that having a solid calendar would be important, and I didn’t feel good about relying on a module that seemed to be pushing users more and more towards a paid model. I’m grateful to Jurgen and everyone who worked on FullCalendar before us for creating such a robust and extensible code base

The Drupal Association has published this guest blog on behalf of HeroDevs.

The official end-of-life (EOL) date for Drupal 7 is January 5, 2025. However, as outlined in the PSA issued on June 7, 2023, the Drupal Security Team announced a change in their support strategy that would take effect before the official EOL date. Starting August 1, 2023, they implemented a reduced support structure for moderately critical Drupal 7 issues.

Why the Reduced Support Structure Matters

When a Drupal 7 module is marked as unsupported, it means that no further updates or security patches will be provided. This situation can leave your site vulnerable to potential security risks and negatively impact performance. As highlighted in the PSA, the Drupal Security Team follows a structured process: they first notify maintainers and provide them with a two-week window to respond and address the issue. If maintainers do not act within this timeframe, the module may be marked as unsupported, and support will cease altogether. This can create significant challenges, particularly for sites reliant on these modules. 

HeroDevs’ Proactive and Comprehensive Approach  

At HeroDevs, we understand the urgency of this issue. We’ve proactively stepped in to bridge the gap by forking and maintaining modules that are no longer supported by their original maintainers, with Drupal 7 Never-Ending Support. Our approach means that even as official support dwindles, your modules continue to receive the necessary updates and fixes. By taking over security maintenance, we help keep your site secure and operational, allowing you to focus on what matters most without worrying about vulnerabilities or disruptions.

Forking and Maintaining Unsupported Modules: HeroDevs has already begun forking and maintaining modules that have been dropped by their original maintainers in the last year. This approach makes sure that essential functionality remains intact and that any emerging security vulnerabilities are promptly addressed. By doing so, we help maintain the security and integrity of your site even as support from the Drupal community wanes.

Guidance for Custom and Legacy Modules: While custom modules and unique code are not covered under the standard SLA, HeroDevs provides guidance and support to help you integrate and maintain these solutions. We collaborate with you to ensure that your custom developments are compatible and functional with our Drupal 7 NES offering.

Maintaining Compatibility and Functionality: Beyond just security patches, HeroDevs works to test the compatibility of your modules with the evolving web landscape. We address compatibility issues and provide a seamless experience for developers working with legacy systems. This comprehensive support approach helps you avoid disruptions and maintain smooth operations.

Conclusion

As the Drupal 7 ecosystem transitions into its extended support phase, HeroDevs is committed to delivering robust and proactive support for unsupported modules. Our dedication to maintaining security, functionality, and compatibility means you can rely on us to safeguard your Drupal 7 site and navigate the end-of-life transition with confidence. With HeroDevs by your side, you can focus on planning your migration or upgrades while we handle the challenges of unsupported modules. Contact us to learn more about Drupal 7 NES.

Python has several pieces of syntax that are syntactic sugar. This sugar is syntax that isn’t strictly necessary but gives Python some of its flavor as a readable, beginner-friendly, and powerful language. In this tutorial, you’ll explore some of Python’s most used pieces of syntactic sugar.

In practice, you already use most of these pieces of syntax, as they include many well-known Pythonic constructs. As you read on, you’ll see how Python works under the hood and learn how to use the language efficiently and securely.

In this tutorial, you’ll learn:

• What syntactic sugar is
• How syntactic sugar applies to operators
• How assignment expressions are syntactic sugar
• How for loops and comprehensions are syntactic sugar
• How other Python constructs are also syntactic sugar

To get the most out of this tutorial, you should be familiar with the basics of Python, including operators, expressions, loops, decorators, classes, context managers, and more.

Interactive Quiz

Syntactic Sugar: Why Python Is Sweet and Pythonic

You can take this quiz to test your understanding of Python's most common pieces of syntactic sugar and how they make your code more Pythonic and readable.

Syntactic Sugar

In programming, syntactic sugar refers to pieces of syntax that simplify the code and make it more readable or concise. Syntactic sugar lets you express things in a clearer and more readable way.

It makes the language sweeter for human use: things can be expressed more clearly, more concisely, or in an alternative style that some may prefer. (Source)

However, syntactic sugar is something that you may not need in practice because you can get the same result using a different, and often more involved, construct.

Note: This tutorial is slightly inspired by Brett Cannon’s series of posts about unraveling syntactic sugar in Python. In that series, Brett goes deep into each piece of syntactic sugar. You can check out the series if you’d like a detailed discussion of the syntax constructs covered in this tutorial and others.

Python has many pieces of syntactic sugar that you’ll regularly use in your code. These syntax constructs make Python more readable, quicker to write, and user-friendly. Understanding these syntactic sugar pieces and their significance will help you better understand the inner workings of Python.

In rare situations, you’ll find that desugared versions of a given piece of syntactic sugar can better fulfill your needs. So, knowing about the alternative code to a given sugar can be a good skill to have.

Operators in Python

As with most programming languages, Python makes extensive use of operators. You’ll find several categories of operators, including arithmetic, assignment, augmented assignment, comparison, Boolean, and membership operators. All these operators are part of Python’s syntactic sugar constructs because they let you write expressions in a quick and readable way.

Note: To dive deeper into Python operators, check out the Operators and Expressions in Python tutorial.

For example, arithmetic operators allow you to create math expressions that are quick to write and read because they look pretty similar to what you learned in math class:

Python >>> 5 + 7 12 >>> 10 - 4 6 >>> 2 * 4 8 >>> 20 / 2 10 Copied!

In the first example, you use the plus operator (+) to add two numbers. In the second example, you use the subtraction operator (-) to subtract two numbers. The final two examples perform multiplication and division.

Python supports its arithmetic operators through special methods. Here’s a quick summary:

Operator Operation Method + Addition .__add__() - Subtraction .__sub__() * Multiplication .__mul__() / Division .__truediv__() // Integer division .__floordiv__() ** Exponentiation .__pow__()

What does it mean to say Python supports its operators through special methods? It means that every time you use an operator, Python calls the corresponding special method under the hood.

Note: To learn more about special methods, also known as magic or dunder methods, check out Python’s Magic Methods: Leverage Their Power in Your Classes.

To illustrate, here’s how you can express the arithmetic operations you wrote earlier using the appropriate special methods:

When setting up your YubiKey you have the option to require the user to touch the device to authorize an operation (be it signing, decrypting, or authenticating). While web browsers often provide clear prompts for this, other applications like SSH or GPG will not. Instead the operation will just hang without any visual indication that user input is required. The YubiKey itself will blink, but depending on where it is plugged in that is not very visible.

yubikey-touch-detector (fresh in unstable) solves this issue by providing a way for your desktop environment to signal the user that the device is waiting for a touch. It provides an event feed on a socket that other components can consume. It comes with libnotify support and there are some custom integrations for other environments.

For GNOME and KDE libnotify support should be sufficient, however you still need to turn it on:

$ mkdir -p ~/.config/yubikey-touch-detector $ sed -e 's/^YUBIKEY_TOUCH_DETECTOR_LIBNOTIFY=.*/YUBIKEY_TOUCH_DETECTOR_LIBNOTIFY=true/' \ < /usr/share/doc/yubikey-touch-detector/examples/service.conf.example \ > ~/.config/yubikey-touch-detector/service.conf $ systemctl --user restart yubikey-touch-detector

I would still have preferred a more visible, more modal prompt. I guess that would be an exercise for another time, listening to the socket and presenting a window. But for now, desktop notifications will do for me.

PS: I have not managed to get SSH's no-touch-required to work with YubiKey 4, while it works just fine with a YubiKey 5.

Managing Enterprise-Level Drupal Projects Editor Mon, 10/14/2024 - 14:16

In this era where websites are like storefronts for many businesses, there is an increasing need for strong and flexible CMS. More than 2.3 million websites worldwide, including some of the biggest and most complex digital platforms, use Drupal!
But, handling large Drupal projects for enterprises is a twist. As the need for complex digital experiences grows, managing such setups comes with many difficulties. You have to make certain that everything works smoothly together, from integrating well with current systems to keeping high-level safety measures intact while also optimizing performance to handle heavy traffic.

Community Driven Development For many years in the Drupal community, I’ve found that my greatest pleasure is not in actually creating the next awesome feature (and, wow, we have some awesome features coming…) but in helping to mentor those who will in the future. Recently, an opportunity came up that interested me a lot. Cambridge University Press & Assessment were looking for a seasoned Drupal developer to help grow the in-house team as they deliver projects built on the platform. I could hardly say no! I very much wanted to look at how better active participation in the community can be a key driver for development of the team’s capabilities.. Rachel Mon, 10/14/2024 - 09:01 Tags

What is an API gateway? 2024-10-14, by Dariusz Suchojad

In this article, we are going to use Zato in its capacity as a multi-protocol Python API gateway - we will integrate a few popular technologies, accepting requests sent over protocols commonly used in frontend systems, enriching and passing them to backend systems and returning responses to the API clients using their preferred data formats. But first, let's define what an API gateway is.

Clearing up the terminology

Although we will be focusing on complex API integrations later on today, to understand the term API gateway we first need to give proper consideration to the very term gateway.

What comes to mind when we hear the word "gateway", and what is correct etymologically indeed, is an opening in an otherwise impermissible barrier. We use a gateway to access that which is in other circumstances inaccessible for various reasons. We use it to leave such a place too.

In fact, both "gate" and the verb "to go" stem from the same basic root and that, again, brings to mind a notion of passing through space specifically set aside for the purpose of granting access to what normally would be unavailable. And once more, when we depart from such an area, we use a gateway too.

From the perspective of its true intended purpose, a gateway letting everyone in and out as they are would amount to little more than a hole in a wall. In other words, a gateway without a gate is not the whole story.

Yes, there is undoubtedly an immense aesthetic gratification to be drawn from being close to marvels of architecture that virtually all medieval or Renaissance gates and gateways represent, but we know that, nowadays, they do not function to the fullest of their capacities as originally intended.

Rather, we can intuitively say that a gateway is in service as a means of entry and departure if it lets its operators achieve the following, though not necessarily all at the same time, depending on one's particular needs:

• Telling arrivals where they are, including projection of might and self-confidence
• Confirming that arrivals are who they say they are
• Checking if their port of origin is friendly or not
• Checking if they are allowed to enter that which is protected
• Directing them to specific areas behind the gateway
• Keeping a long term and short term log of arrivals
• Answering potential questions right by the gate, if answers are known to gatekeepers
• Cooperating with translators and coordinators that let arrivals make use of what is required during their stay

We can now recognize that a gateway operates on the border of what is internal and external and in itself, it is a relatively narrow, though possibly deep, piece of an architecture. It is narrow because it is only through the gateway that entry is possible but it may be deeper or not, depending on how much it should offer to arrivals.

We also keep in mind that there may very well be more than a single gateway in existence at a time, each potentially dedicated to different purposes, some overlapping, some not.

Finally, it is crucial to remember that gateways are structural, architectural elements - what a gateway should do and how it should do it is a decision left to architects.

With all of that in mind, it is easy to transfer our understanding of what a physical gateway is into what an API one should be.

• API clients should be presented with clear information that they are entering a restricted area
• Source IP addresses or their equivalents should be checked and requests rejected if an IP address or equivalent information is not among the allowed ones
• Usernames, passwords, API keys and similar representations of what they are should be checked by the gateway
• Permissions to access backend systems should be checked seeing as not every API client should have access to everything
• Requests should be dispatched to relevant backend systems
• Requests and responses should be logged in various formats, some meant to be read by programs and applications, some by human operators
• If applicable, responses can be served from the gateway's cache, taking the burden off the shoulders of the backend systems
• Requests and responses can be transformed or enriched which potentially means contacting multiple backend systems before an API caller receives a response

We can now define an API gateway as an element of a systems architecture that is certainly related to security, permissions and granting or rejecting access to backend systems, applications and data sources. On top of it, it may provide audit, data transformation and caching services. The definition will be always fluid to a degree, depending on an architect's vision, but this is what can be expected from it nevertheless.

Having defined what an API gateway is, let's create one in Zato and Python.

Clients and backend systems

In this article, we will integrate two frontend systems and one backend application. Frontend ones will use REST and WebSockets whereas the backend one will use AMQP. Zato will act as an API gateway between them all.

Not granting frontend API clients direct access to backend systems is usually a good idea because the dynamics involved in creation of systems on either side are typically very different. But they still need to communicate and hence the usage of Zato as an API gateway.

Python code

First, let's show the Python code that is needed to integrate the systems in our architecture:

# -*- coding: utf-8 -*- # Zato from zato.server.service import Service class APIGateway(Service): """ Dispatches requests to backend systems, enriching them along the way. """ name = 'api.gateway' def handle(self): # Enrich incoming request with metadata .. self.request.payload['_receiver'] = self.name self.request.payload['_correlation_id'] = self.cid self.request.payload['_date_received'] = self.time.utcnow() # .. AMQP configuration .. outconn = 'My Backend' exchange = '/incoming' routing_key = 'api' # .. publish the message to an AMQP broker .. self.out.amqp.send(data, outconn, exchange, routing_key) # .. and return a response to our API client. self.response.payload = {'result': 'OK, data accepted'}

There are a couple of points of interest:

• The gateway service enriches incoming requests with metadata but it could very well enrich it with business data too, e.g. it could communicate with yet another system to obtain required information and only then pass the request to the final backend system(s)

• In its current form we send all the information to AMQP brokers only but we could just as well send it to other systems, possibly modifying the requests along the way

• The code is very abstract and all of its current configuration could be moved to a config file, Redis or another data source to make it even more high-level

• Security configuration and other details are not declared directly in the body of the gateway service but they need to exist somewhere - we will describe it in the next section

Configuration

In Zato, API clients access the platform's services using channels - let's create a channel for REST and WebSockets then.

First REST:

Now WebSockets:

We create a new outgoing AMQP connection in the same way:

Using the API gateway

At this point, the gateway is ready - you can invoke it from REST or WebSockets and any JSON data it receives will be processed by the gateway service, the AMQP broker will receive it, and API clients will have replies from the gateway as JSON responses.

Let's use curl to invoke the REST channel with JSON payload on input:

$ curl http://api:<password-here>@localhost:11223/api/v1/user ; echo curl --data-binary @request.json http://localhost:11223/api/v1/user ; echo {"result": "OK, data accepted"} $

Taken together, the channels and the service allowed us to achieve this:

• Multiple API clients can access the backend AMQP systems, each client using its own preferred technology
• Client credentials are checked on input, before the service starts to process requests (authentication)
• It is possible to assign RBAC roles to clients, in this way ensuring they have access only to selected parts of the backend API (authorization)
• Message logs keep track of data incoming and outgoing
• Responses from channels can be cached which lessens the burden put on the shoulders of backend systems
• Services accepting requests are free to modify, enrich and transform the data in any way required by business logic. E.g., in the code above we only add metadata but we could as well reach out to other applications before requests are sent to the intended recipients.

We can take it further. For instance, the gateway service is currently completely oblivious to the actual content of the requests.

But, since we just have a regular Python dict in self.request.payload, we can with no effort modify the service to dispatch requests to different backend systems, depending on what the request contains or possibly what other backend systems decide the destination should be.

Such additional logic is specific to each environment or project which is why it is not shown here, and this is also why we end the article at this point, but the central part of it all is already done, the rest is only a matter of customization and plugging in more channels for API clients or outgoing connections for backend systems.

Finally, it is perfectly fine to split access to systems among multiple gateways - each may handle requests from selected technologies on the one hand but on the other hand, each may use different caching or rate-limiting policies. If there is more than one, it may be easier to configure such details on a per-gateway basis.

Your new Django project uses Python 3.13.

You’re really looking forward to using the new REPL… but python manage.py shell just shows the same old Python REPL. What gives?

Well, Django’s management shell uses Python’s code module to launch a custom REPL, but the code module doesn’t (yet) use the new Python REPL.

So you’re out of luck… or are you?

How stable do you need your shell command to be?

The new Python REPL’s code lives in a _pyrepl package. Surely there must be some way to launch the new REPL using that _pyrepl package!

First, note the _ before that package name. It’s _pyrepl, not pyrepl.

Any solution that relies on this module may break in future Python releases.

So… should we give up on looking for a solution, if we can’t get a “stable” one?

I don’t think so.

My shell command doesn’t usually need to be stable in more than one version of Python at a time. So I’m fine with a solution that attempts to use the new REPL and then falls back to the old REPL if it fails.

A working solution

So, let’s look at a working solution.

Stick this code in a management/commands/shell.py file within one of your Django apps:

1 2 3 4 5 6 7 8 9 10 """Python 3.13 REPL support using the unsupported _pyrepl module.""" from django.core.management.commands.shell import Command as BaseShellCommand class Command(BaseShellCommand): shells = ["ipython", "bpython", "pyrepl", "python"] def pyrepl(self, options): from _pyrepl.main import interactive_console interactive_console() How it works

Django’s shell command has made it very simple to add support for your favorite REPL of choice.

The code for the shell command loops through the shells list and attempts to run a method with that name on its own class. If an ImportError is raised then it attempts the next command, stopping once no exception occurs.

Our new command will try to use IPython and bpython if they’re installed and then it will try the new Python 3.13 REPL followed by the old Python REPL.

If Python 3.14 breaks our import by moving the interactive_console function, then an ImportError will be raised, causing us to fall back to the old REPL after we upgrade to Python 3.14 one day. If instead, the interactive_console function’s usage changes (maybe it will require arguments) then our shell command will completely break and we’ll need to manually fix it when we upgrade to Python 3.14.

What’s so great about the new REPL?

If you’re already using IPython or BPython as your REPL and you’re enjoying them, I would stick with them.

Third-party libraries move faster than Python itself and they’re often more feature-rich. IPython has about 20 years worth of feature development and it has features that the built-in Python REPL will likely never have.

If you’re using the default Python REPL though, this new REPL is a huge upgrade. I’ve been using it as my default REPL since May and I love it. See my screencast on Python 3.13 for my favorite features in the new REPL.

This year, one of the projects I was involved in at Sentry was the launch of The Open Source Pledge. The idea behind it is simple: companies pledge an amount proportional to the number of developers they employ to fund the Open Source projects they depend on. I have written about this before.

Since then, I've had the chance to engage in many insightful discussions about Open Source funding and licensing. In the meantime we have officially launched the pledge, and almost simultaneously WordPress entered a crisis. At the heart of that crisis is a clash between Open Source ideals and financial interests by people other than the original creators.

You might have a lot of opinions on David Heinemeier Hansson, but I encourage you to read two of his recent posts on that very topic. In Automattic is doing open source dirty David is laying out the case that Automattic has no right to impose moral obligations on beyond the scope of the license. This has been followed by Open source royalty and mad kings in which he goes deeper into the fallout that Matt Mullenweg (the creator of WordPress) is causing with his fight.

I'm largely in agreement with the posts. However I want to talk a bit about some pretty significant difference between David's opinions on Open Source funding (on which these posts appear to be based): the money element. In 2013 David wrote the following about money and Open Source:

[…] it's tempting to cash in on goodwill earned. […] It's a cliché, but once you've sold out, the goodwill might well be spent for good.

[…] part of the reason much of open source is so good, and often so superior to closed-source commercial projects, is the natural boundary of constraints. If you are not being paid or otherwise compensated directly for your work, you're less likely to needlessly embellish it. […]

—David Heinemeier Hansson, The perils of mixing open source and money

At face value, this suggests that Open Source and money shouldn’t mix, and that the absence of monetary rewards fosters a unique creative process. There's certainly truth to this, but in reality, Open Source and money often mix quickly.

If you look under the cover of many successful Open Source projects you will find companies with their own commercial interests supporting them (eg: Linux via contributors), companies outright leading projects they are also commercializing (eg: MariaDB, redis) or companies funding Open Source projects primarily for marketing / up-sell purposes (uv, next.js, pydantic, …). Even when money doesn't directly fund an Open Source project, others may still profit from it, yet often those are not the original creators. These dynamics create stresses and moral dilemmas.

I’ve said this before, but it’s no coincidence that Rails has a foundation, large conferences, a strong core team, and a trademark, while Flask has none of it. There are barriers and it takes a lot of energy and determination to push a project to a level where it can sustain itself.

Rails pushed through this barrier. I never did with any of my projects and I'm at peace with that. I got to learn a lot through my Open Source work, I achieved a certain level of notoriety that I benefit from. I built a meaningful career by leveraging my work and I even met my wonderful wife that way. All are consequences of my Open Source contributions. There were clear and indisputable benefits to it and by all accounts I'm a happy and grateful person.

But every now and then doubts creep in and I wonder if I should have done something more commercial with Flask, or if I should have pushed Rye further. As much as I love listening to Charlie talking about uv, there is also an unavoidable doubt lingering there what could have been if I dared to build out Rye with funding on my own.

Over the years, I have seen too many of my colleagues and acquaintances struggle one way or another. Psychological, mentally and professionally. Midlife crises, burnout, health, and dealing with a strong feeling of dread and disappointment. Many of this as a indirect or even direct result of their Open Source work. While projects like Rails and Laravel are great examples of successful open source stewardship, they are also outliers. Many others don't survive or grow to that level.

And yet even some of those lighthouse projects can become fallen stars and face challenges. WordPress by all accounts is a massive success. WordPress is in the top 1% of open source projects in terms of impact, success, and financial return for its creator. Yet despite that — and it finding an actual business model to commercialize it — its creator suffers from the same fate as many small Open Source libraries: a feeling of being wronged.

This is where the lines between law and morality blur. Matt feels mistreated, especially by a private equity firm, but neither trademarks nor license terms can resolve the issue for him. It’s a moral question, and sadly, Matt’s actions have alienated many who would otherwise support him. He's turning into a “mad king” and behaving immoral in his own ways.

The reality is that we humans are messy and unpredictable. We don't quite know how we will behave until we have been throw into a particular situation. Open Source walks a very fine line, and anyone claiming to have all the answers probably doesn't. I certainly don't.

Is it a wise to mix Open Source and money? Maybe not. Yet I also believe it's something that is just a reality we need to navigate. Today there are some projects too small to get any funding (xz) and there are projects large enough to find some way to sustain by funneling money to it (Rails, WordPress).

We target with the Pledge small projects in particular. It's our suggestion of how to give to projects for which the barrier to attract funding is too high. At the same time I recognize all the open questions it leaves. There are questions about tax treatments, there are questions about sustainabilty and incentives, questions about distribution and governance.

I firmly believe that the current state of Open Source and money is inadequate, and we should strive for a better one. Will the Pledge help? I hope for some projects, but WordPress has shown that we need to drive forward that conversation of money and Open Source regardless of thes size of the project.

This is the fifth article in a series of articles about the Batch API in Drupal. The Batch API is a system in Drupal that allows data to be processed in small chunks in order to prevent timeout errors or memory problems.

So far in this series we have looked at creating a batch process using a form, followed by creating a batch class so that batches can be run through Drush, using the finished state to control batch processing and then processing CSV files through a batch process. All of these articles give a good grounding of how to use the Drupal Batch API.

In this article we will take a closer look at how the batch system processes items by creating a batch run inside an already running batch process. This will show how batch systems run and what happens when you try to add additional operations to a running batch.

Let's setup the initial batch operation.

Setting Up The Batch

The setup for this batch process is similar to the batch processes on the other articles. This will kick off a batch process that will process 1,000 items in chunks of 100 each.

A long time ago….

A long time ago a computer was a woman (I think almost exclusively a women, not a man) who was employed to do a lot of repetitive mathematics – typically for accounting and stock / order processing.

Then along came Lyons, who deployed an artificial computer to perform the same task, only with fewer errors in less time. Modern day computing was born – we had entered the age of the Digital Computer.

These computers were large, consumed huge amounts of power but were precise, and gave repeatable, verifiable results.

Over time the huge mainframe digital computers have shrunk in size, increased in performance, and consume far less power – so much so that they often didn’t need the specialist CFC based, refrigerated liquid cooling systems of their bigger mainframe counterparts, only requiring forced air flow, and occasionally just convection cooling. They shrank so far and became cheep enough that the Personal Computer became to be, replacing the mainframe with its time shared resources with a machine per user. Desktop or even portable “laptop” computers were everywhere.

We networked them together, so now we can share information around the office, a few computers were given specialist tasks of being available all the time so we could share documents, or host databases these servers were basically PCs designed to operate 24×7, usually more powerful than their desktop counterparts (or at least with faster storage and networking).

Next we joined these networks together and the internet was born. The dream of a paperless office might actually become realised – we can now send email (and documents) from one organisation (or individual) to another via email. We can make our specialist computers applications available outside just the office and web servers / web apps come of age.

Fast forward a few years and all of a sudden we need huge data-halls filled with “Rack scale” machines augmented with exotic GPUs and NPUs again with refrigerated liquid cooling, all to do the same task that we were doing previously without the magical buzzword that has been named AI; because we all need another dot com bubble or block chain band waggon to jump aboard. Our AI enabled searches take slightly longer, consume magnitudes more power, and best of all the results we are given may or may not be correct….

Progress, less precise answers, taking longer, consuming more power, without any verification and often giving a different result if you repeat your question AND we still need a personal computing device to access this wondrous thing.

Remind me again why we are here?

 LATE NEWS

 I haven't blogged until now: I should have done from Thursday onwards.

It's a joy to be here in Cambridge at ARM HQ. Lots of people I recognise from last year  here: lots *not* here because this mini-conference is a month before the next one in Toulouse and many people can't attend both.

Two days worth of chatting, working on bits and pieces, chatting and informal meetings was a very good and useful way to build relationships and let teams find some space for themselves.

Lots of quiet hacking going on - a few loud conversations. A new ARM machine in mini-ITX format - see Steve's blog.

Two days worth of talks for Saturday and Sunday. For some people, this is a first time. Lightning talks are particularly good to break down barriers - three slides and five minutes (and the chance for a bit of gamesmanship to break the rules creatively).

Longer talks: a couple from Steve Capper of ARM were particularly helpful to those interested in upcoming development. A couple of the talks in the schedule are traditional: if the release team are here, they tell us what they are doing, for example.

ARM are main sponsors and have been very generous in giving us conference and facilities space. Fast network, coffee and interested people - what's not to like :)

Wikimedia Commons, the Wikimedia project for freely licensed media files, also contains a bunch of photos by me and photos of me at various events. While I don't think Commons is going away anytime soon, I would still like to have a local copy of those images available on my own storage hardware.

Obviously this requires some way to query for photos you want to download. I'm using Commons categories for this, since that's easy to implement and works for both use cases. The Commons community tends to come up with very specific categories that you can use, and if not, you can usually categorize the files yourself.

thankfully Commons has no such thing as a Conflict of interest (COI) policy

There is almost an existing tool for this: Sam Wilson's mwcli project has support for exporting images one has uploaded to Commons. However I couldn't use that to upload photos of me others have uploaded, plus it's written in PHP and I don't exactly want to deal with the problem of figuring out how to package it in a way I could neatly install it on my NAS.

So I wrote my own tool for it, called comload. It's written in Python because Python is easy to deploy (I can just throw it in a .deb and upload it to my internal repository), and because I did not find a Go library to handle Action API pagination for me. The basic usage is like this:

$ comload --subcats "Taavi Väänänen"

This will download any files in Category:Taavi Väänänen and its sub-categories to the current directory. Former image versions, as well as the image description and SDC data, if any, is also included. And it's smart enough to not download any files that are already there on future runs, so you can just throw it in a systemd timer to get any future files. I'd still like it to handle moved files without creating a duplicate copy, but otherwise I'm really happy with the current state.

comload is available from PyPI and from my Git server directly, and is licensed under the GPLv3.
