Debian Day in Santa Maria - RS 2024 was held after a 5-year hiatus from the previous version of the event. It took place on the morning of August 16, in the Blue Hall of the Franciscan University (UFN) with support from the Debian community and the Computing Practices Laboratory of UFN.

The event was attended by students from all semesters of the Computer Science, Digital Games and Informational Systems, where we had the opportunity to talk to the participants.

Around 60 students attended a lecture introducing them to Free and Open Source Software, Linux and were introduced to the Debian project, both about the philosophy of the project and how it works in practice and the opportunities that have opened up for participants by being part of Debian.

After the talk, a packaging demonstration was given by local DD Francisco Vilmar, who demonstrated in practice how software packaging works in Debian.

I would like to thank all the people who helped us:

• Debian Project
• Professor Ana Paula Canal (UFN)
• Professor Sylvio André Garcia (UFN)
• Laboratory of Computing Practices
• Francisco Vilmar (local DD)

And thanks to all the participants who attended this event asking intriguing questions and taking an interest in the world of Free Software.

Faceted search offers users with a superior search experience by displaying filters against their search results. It is particularly useful for websites having large catalogues and listings. Once the user types in their search query, they will be presented with a list of relevant filter options to further narrow down their search. These filtering elements are facets.Previously Facet API in Drupal 9, the Facet module in Drupal 10 enables your website with faceted searching abilities. Let’s look at configuring and implementing Faceted search with Drupal’s own search server, Search API. What is Faceted Search? If your users are finding it hard to see what they are searching for even after keying in their search query, they are bound to get frustrated. Faceted search provides users with multiple filters at the same time for the various attributes of the content. The facets provided are based on the search query the user has executed. Facets will also display the number of matched results (usually within brackets) next to it. Let’s take a look at this below screenshot to understand Facets better. In one of our recent Drupal projects, a quick search for Homes in Columbia on this website presents to you with facets like Communities, Hot Deals, Quick Move-ins and more. You will also see the count of the results next to each facet. So, a query with “Columbia” keyword is sent to the search server to retrieve the already configured and indexed categories (Communities, Hot Deals, etc.) Installing the Facets Module for Drupal 10 As previously discussed, we will be implementing Faceted search using Drupal’s Search API module.  Step 1: Enabling the modules Install and enable these modules •    The Facet Module •    Search API module Step 2: Creating Content Types Create the content you would like to include in the faceted search by adding Content types as shown below. You can also use the default content types provided by Drupal. Step 3: Configuring the Search server Navigate to Configuration -> Search and metadata -> Search-API from the admin interface to configure your search server. Give a name to your search server (here - data server).  Step 4: Configuring the Search Index Next, configure the search index to improve the search performance. Navigate to Configuration -> Search and metadata -> Search-API -> Index -> data_index. Give a name to your index and then select Content as your Datasources since we will be indexing the Content entities here. You can then move on to the next section - Configuring the Datasource (here – Content). Here you can choose to select all the bundles or only select a few from the below list to index. Next, select your server that you had already created (here - data server). Select the “Index items immediately” option to begin the indexing process. Click on Save. Step 5: Adding Fields for Indexing Next, we need to add Fields to be indexed. Navigate to Configuration -> Search and metadata ->Search API -> data index and select the Fields tab. Click on the Add fields button to create fields according to your requirement. Step 6: Indexing the Content Under the same location, click on the View tab to start the process of indexing your content. In the Start Indexing Now section, click on the Index Now button. It will then show you a progress bar with the status of the number of items that have been indexed. Step 7: Creating a View Now we will be creating a view for the data that needs to be indexed and displayed to your users. Navigate to Structure -> Views -> Add View. Give a name for the View.Under View Settings dropdown list, select the index that you have created in Step 4.Create a page for your search results by clicking on the Create a page checkbox under the Page Settings tab. Give a name and a path for the same. Under Items to Display, select 0 if you want to display all the results in one page. Else, select a number of results to be displayed. Under Page Display settings, you can select the format in which you want to display your results – Table, Grid, HTML list or Unformatted list. We have selected Unformatted list here. Click on Save. Step 8: Adding Fields to the View Here we will be adding fields that we have indexed earlier to the View.Go to Views, click on Add button next to the Fields section. Select the Fields, click on Add and Configure. Under Render Settings, select the Link to Content checkbox so that the results displayed are clickable.Click Save. Step 9: Configuring the Facets Now let’s begin configuring and enabling the facets. Navigate to Configuration -> Search and meta data -> FacetsClick on the Add Facet button. Select the Facet Source – This will be your View that you created previously.Select the Field – This will display the fields you had added for indexing in Step 5.Give a name to the Facet.Click on Save. Next, you will then see more configuration options for displaying the facets (as shown in the below image). Widgets will list out a number of options like List of links, array, dropdown, etc. You can choose what suits your website the best.Select the “Transform entity ID to label” to avoid displaying the machine name of the content type.Click on Save. Step 10: Placing the Facet blocks in the chosen page regions  Next, place the Facets you created as blocks in a page region of your choice. Navigate to Structure -> Block Layout. Select the region of the page where you would like to place the block containing the Facets.Here, we are selecting Sidebar. Click on the Place Block button next to the Sidebar.In the next dialog box, search for the Facet name and click on Place Block. In the Configure Block section, mention the Search page path that you had previously created. Here -“site-search” is our page we had created. Give a display name for your Block and select the Display title checkbox if you want the block name to be displayed (here – Type).Click on Save Block. The Result And just like that, your faceted search page and functionality is ready! Notice the Facet called Type (display name) that has Basic page and Article listed as content types to filter against.(Note: Since there is no content available under ‘Basic Page’, it will not show up in the filter).   Select Type as ‘Person’   Select Type as ‘Article’ Final Thoughts Implementing faceted search provides users with an easy and fast search experience. In this tutorial, we have used Search API as the search engine. You could also use search servers like Apache Solr, Search API Solr search or Elasticsearch with Drupal 8, whatever suits your requirements. As a leading Drupal development company, Specbee’s Drupal experts can help you build exemplary search experiences. Contact us to know more.

Simon Morvan discusses EvolvingWeb, Drupal development, and CKEditor 5 migration at DrupalCon Portland 2024.

Release 0.6.37 of the digest package arrived at CRAN today and has also been uploaded to Debian.

digest creates hash digests of arbitrary R objects. It can use a number different hashing algorithms (md5, sha-1, sha-256, sha-512, crc32, xxhash32, xxhash64, murmur32, spookyhash, blake3,crc32c, xxh3_64 and xxh3_128), and enables easy comparison of (potentially large and nested) R language objects as it relies on the native serialization in R. It is a mature and widely-used package (with 70.8 million downloads just on the partial cloud mirrors of CRAN which keep logs) as many tasks may involve caching of objects for which it provides convenient general-purpose hash key generation to quickly identify the various objects.

This release updates one of the different hashing source functions which, to remain close to their upstream, used Free() and Calloc() (uppercased to use the R allocator) but not the prefixed stricter versions R_Free() and R_Calloc(). R will switch to enforcing these in the next release next year. Kevin had noticed (while doing some other testing) that this now fails under R-devel (with a switch set), and prepares a very nice and clean PR to take care of it. As of today, CRAN is now sending ‘please fix, or else …’ notes so it was a good time to send this to CRAN. We also updated some remaining http URLs in the README.md to https, and switched to Author/Maintainer field to the now also mandatory Authors@R.

My CRANberries provides a summary of changes to the previous version. For questions or comments use the issue tracker off the GitHub repo. For documentation (including the changelog) see the documentation site.

This post by Dirk Eddelbuettel originated on his Thinking inside the box blog. Please report excessive re-aggregation in third-party for-profit settings.

This article looks at how to limit the content types in a Django model.

In the KDE world, famously there was that weekend where DCOP (Desktop Communicating Objects Protocol) was created, setting the stage for things like KParts. GNOME picked the CORBA object model, and much later the Free Desktop world settled on DBus as a message-passing API. But even at the time, there were other message-passing APIs. At work-work I use one, called SIMPL, which is kind of shout-out to the late ’90s of DCOP.

Please note that my presentation of “history” is just what I remember now of events that were already “tales told ‘round the campfire” 15 years ago. Corrections welcome (by email).

At work-work SIMPL is just a given, and it’s got wrappers and abstractions so that there’s a decent C++ style API around it. At its heart it is a point-to-point message-passing API with no policy at all about the payload of messages. That is both a blessing – no policy means it can be used for whatever kind of messages you think is necessary – and a curse – no policy means that you end up writing a bunch of abstractions to represent the messages that you actually use.

Code at the wrapped-in-C++ level looks something like this (effectively obscuring the underlying transport):

auto reply = CoordinatorTask().Send(requests::GetCurrentUser()); if(reply.has_value()) { do_something(reply.value().username); ...

There does not seem to be much online about SIMPL anymore. There is a LinuxDevices article from 2000 when SIMPL was under some active development as an Open Source project, there’s a LWN comment from 2015 that mentions it still, and there’s a Wikipedia article on it, as a historical note. Note that the Website link on wikipedia goes to something that is now a spam domain. I can’t quickly find sources anymore.

I do wonder at the chances of history that made desktop developers at the time entirely miss out on this existing message-passing mechanism – perhaps the SIMPL authors were too focused on industrial automation and not visible in the X11 desktop space, and not visible on SunOS and other platforms where a fair bit of KDE development happened at the time.

One thing that the SIMPL library developers emphasize repeatedly in documentation (there’s a book) is a philosophy of doing one thing and doing it well. So serialization and message payloads are not part of this – no policy. So security and access control are not part of his – no policy. Those concerns are things that can go into a different API layer on top of SIMPL.

Something else that the SIMPL authors emphasize is doing one thing and doing it well. That applies to the applications that use SIMPL, in particular. And that translates, in the depths of the library, to being able to register only one name for an application (for purposes of discovering what other applications there are, each application has a unique name in the system). It translates into a lack of thread safety, due to the use of global state. It translates into a contextless API, so all an application can do is call “give me the next incoming message”. There’s no concept of an event-loop, and no obvious mechanisms for integrating SIMPL message-handling into another event loop (like an X11 loop).

For me personally this means that I need to re-tool my brain during the trip between home and work, switching of Qt wrappers around DBus to work-work wrappers around SIMPL and the subtleties of each. In practice, that means mostly cursing QtDBus (because of the relative amount of time I put into both).

(The issues described in this post have been fixed, I have not exhaustively researched whether any other issues exist)

Feeld is a dating app aimed largely at alternative relationship communities (think "classier Fetlife" for the most part), so unsurprisingly it's fairly popular in San Francisco. Their website makes the claim:

Can people see what or who I'm looking for?
No. You're the only person who can see which genders or sexualities you're looking for. Your curiosity and privacy are always protected.

which is based on you being able to restrict searches to people of specific genders, sexualities, or relationship situations. This sort of claim is one of those things that just sits in the back of my head worrying me, so I checked it out.

First step was to grab a copy of the Android APK (there are multiple sites that scrape them from the Play Store) and run it through apk-mitm - Android apps by default don't trust any additional certificates in the device certificate store, and also frequently implement certificate pinning. apk-mitm pulls apart the apk, looks for known http libraries, disables pinning, and sets the appropriate manifest options for the app to trust additional certificates. Then I set up mitmproxy, installed the cert on a test phone, and installed the app. Now I was ready to start.

What became immediately clear was that the app was using graphql to query. What was a little more surprising is that it appears to have been implemented such that there's no server state - when browsing profiles, the client requests a batch of profiles along with a list of profiles that the client has already seen. This has the advantage that the server doesn't need to keep track of a session, but also means that queries just keep getting larger and larger the more you swipe. I'm not a web developer, I have absolutely no idea what the tradeoffs are here, so I point this out as a point of interest rather than anything else.

Anyway. For people unfamiliar with graphql, it's basically a way to query a database and define the set of fields you want returned. Let's take the example of requesting a user's profile. You'd provide the profile ID in question, and request their bio, age, rough distance, status, photos, and other bits of data that the client should show. So far so good. But what happens if we request other data?

graphql supports introspection to request a copy of the database schema, but this feature is optional and was disabled in this case. Could I find this data anywhere else? Pulling apart the apk revealed that it's a React Native app, so effectively a framework for allowing writing of native apps in Javascript. Sometimes you'll be lucky and find the actual Javascript source there, but these days it's more common to find Hermes blobs. Fortunately hermes-dec exists and does a decent job of recovering something that approximates the original input, and from this I was able to find various lists of database fields.

So, remember that original FAQ statement, that your desires would never be shown to anyone else? One of the fields mentioned in the app was "lookingFor", a field that wasn't present in the default profile query. What happens if we perform the incredibly complicated hack of exporting a profile query as a curl statement, add "lookingFor" into the set of requested fields, and run it?

Oops.

So, point 1 is that you can't simply protect data by having your client not ask for it - private data must never be released. But there was a whole separate class of issue that was an even more obvious issue.

Looking more closely at the profile data returned, I noticed that there were fields there that weren't being displayed in the UI. Those included things like "ageRange", the range of ages that the profile owner was interested in, and also whether the profile owner had already "liked" or "disliked" your profile (which means a bunch of the profiles you see may already have turned you down, but the app simply didn't show that). This isn't ideal, but what was more concerning was that profiles that were flagged as hidden were still being sent to the app and then just not displayed to the user. Another example of this is that the app supports associating your profile with profiles belonging to partners - if one of those profiles was then hidden, the app would stop showing the partnership, but was still providing the profile ID in the query response and querying that ID would still show the hidden profile contents.

Reporting this was inconvenient. There was no security contact listed on the website or in the app. I ended up finding Feeld's head of trust and safety on Linkedin, paying for a month of Linkedin Pro, and messaging them that way. I was then directed towards a HackerOne program with a link to terms and conditions that 404ed, and it took a while to convince them I was uninterested in signing up to a program without explicit terms and conditions. Finally I was just asked to email security@, and successfully got in touch. I heard nothing back, but after prompting was told that the issues were fixed - I then looked some more, found another example of the same sort of issue, and eventually that was fixed as well. I've now been informed that work has been done to ensure that this entire class of issue has been dealt with, but I haven't done any significant amount of work to ensure that that's the case.

You can't trust clients. You can't give them information and assume they'll never show it to anyone. You can't put private data in a database with no additional acls and just rely on nobody ever asking for it. You also can't find a single instance of this sort of issue and fix it without verifying that there aren't other examples of the same class. I'm glad that Feeld engaged with me earnestly and fixed these issues, and I really do hope that this has altered their development model such that it's not something that comes up again in future.

(Edit to add: as far as I can tell, pictures tagged as "private" which are only supposed to be visible if there's a match were appropriately protected, and while there is a "location" field that contains latitude and longitude this appears to only return 0 rather than leaking precise location. I also saw no evidence that email addresses, real names, or any billing data was leaked in any way)

<p>Dear Readers,<br><br><a href="https://www.thedroptimes.com/42282/drupal-starshot-initiative-now-officially-drupal-cms">The official naming of "Drupal CMS" marks a significant step in the evolution of the product initially developed under the Drupal Starshot Initiative</a>. The name was chosen for its clarity and simplicity, with "CMS" explicitly conveying the product's core function as a content management system. This approach addresses a common issue where users, particularly those unfamiliar with Drupal, often need clarification on what Drupal represents. Incorporating "CMS" into the name immediately defines the product’s purpose, aligning it more closely with industry norms and expectations.</p><p>The selection of "Drupal CMS" also reflects a broader strategy to make Drupal more accessible and understandable to various user groups. Participants in the testing process, especially marketers and designers, appreciated the inclusion of "CMS" in the name. For marketers unfamiliar with Drupal, the new name offered immediate recognition of the product's capabilities. Designers and other industry professionals echoed this sentiment, noting that "CMS" is a widely recognized term that accurately describes the product's function.</p><p>In contrast to Drupal CMS, Drupal Core continues to serve as the foundational framework for Drupal, offering a minimalist approach that is highly customizable but requires more technical expertise to implement fully. While Drupal Core provides the essential building blocks for creating custom web applications, Drupal CMS is designed to be more user-friendly and ready to use out-of-the-box. This distinction is crucial for users choosing between the two, as Drupal CMS comes with pre-configured modules, themes, and settings that streamline the development process, making it an ideal choice for less technical users or those needing rapid deployment.</p><p>The reception of the new name has been positive, particularly because it brings a level of clarity and accessibility that was previously lacking. By deciding to retire the internal code name "Drupal Starshot" after the first official release of Drupal CMS, the community is signaling a shift toward a more transparent and user-centered approach. This renaming simplifies the branding and helps position Drupal more effectively in a competitive market, ensuring that users immediately understand what the product offers and how it can meet their needs.</p><p>With that, let's move on to the important stories from the past week.</p><p><a href="https://www.thedroptimes.com/42278/drupal-association-board-election-2024-voting-now-open">Voting for the 2024 Drupal Association At-Large Board Member election has officially begun</a> as of August 15, 00:00 UTC.

Python supports the object-oriented programming paradigm through classes. They provide an elegant way to define reusable pieces of code that encapsulate data and behavior in a single entity. With classes, you can quickly and intuitively model real-world objects and solve complex problems.

If you’re new to classes, need to refresh your knowledge, or want to dive deeper into them, then this tutorial is for you!

In this tutorial, you’ll learn how to:

• Define Python classes with the class keyword
• Add state to your classes with class and instance attributes
• Provide behavior to your classes with methods
• Use inheritance to build hierarchies of classes
• Provide interfaces with abstract classes

To get the most out of this tutorial, you should know about Python variables, data types, and functions. Some experience with object-oriented programming (OOP) is also a plus. Don’t worry if you’re not an OOP expert yet. In this tutorial, you’ll learn the key concepts that you need to get started and more. You’ll also write several practical examples to help reinforce your knowledge of Python classes.

Interactive Quiz

Python Classes - The Power of Object-Oriented Programming

In this quiz, you'll test your understanding of Python classes. With this knowledge, you'll be able to define reusable pieces of code that encapsulate data and behavior in a single entity, model real-world objects, and solve complex problems.

Getting Started With Python Classes

Python is a multiparadigm programming language that supports object-oriented programming (OOP) through classes that you can define with the class keyword. You can think of a class as a piece of code that specifies the data and behavior that represent and model a particular type of object.

What is a class in Python? A common analogy is that a class is like the blueprint for a house. You can use the blueprint to create several houses and even a complete neighborhood. Each concrete house is an object or instance that’s derived from the blueprint.

Each instance can have its own properties, such as color, owner, and interior design. These properties carry what’s commonly known as the object’s state. Instances can also have different behaviors, such as locking the doors and windows, opening the garage door, turning the lights on and off, watering the garden, and more.

In OOP, you commonly use the term attributes to refer to the properties or data associated with a specific object of a given class. In Python, attributes are variables defined inside a class with the purpose of storing all the required data for the class to work.

Similarly, you’ll use the term methods to refer to the different behaviors that objects will show. Methods are functions that you define within a class. These functions typically operate on or with the attributes of the underlying instance or class. Attributes and methods are collectively referred to as members of a class or object.

You can write classes to model the real world. These classes will help you better organize your code and solve complex programming problems.

For example, you can use classes to create objects that emulate people, animals, vehicles, books, buildings, cars, or other objects. You can also model virtual objects, such as a web server, directory tree, chatbot, file manager, and more.

Finally, you can use classes to build class hierarchies. This way, you’ll promote code reuse and remove repetition throughout your codebase.

In this tutorial, you’ll learn a lot about classes and all the cool things that you can do with them. To kick things off, you’ll start by defining your first class in Python. Then you’ll dive into other topics related to instances, attributes, and methods.

Defining a Class in Python

To define a class, you need to use the class keyword followed by the class name and a colon, just like you’d do for other compound statements in Python. Then you must define the class body, which will start at the next indentation level:

Python Syntax class ClassName: <body> Copied!

In a class’s body, you can define attributes and methods as needed. As you already learned, attributes are variables that hold the class data, while methods are functions that provide behavior and typically act on the class data.

Note: In Python, the body of a given class works as a namespace where attributes and methods live. You can only access those attributes and methods through the class or its objects.

As an example of how to define attributes and methods, say that you need a Circle class to model different circles in a drawing application. Initially, your class will have a single attribute to hold the radius. It’ll also have a method to calculate the circle’s area:

Python circle.py import math class Circle: def __init__(self, radius): self.radius = radius def calculate_area(self): return math.pi * self.radius ** 2 Copied!

In this code snippet, you define Circle using the class keyword. Inside the class, you write two methods. The .__init__() method has a special meaning in Python classes. This method is known as the object initializer because it defines and sets the initial values for the object’s attributes. You’ll learn more about this method in the Instance Attributes section.

Drupal is shifting from a developer-centric framework to a product-oriented platform with the Starshot initiative, aimed at simplifying the site building experience for smaller organizations through Low Code/No Code tools and automatic updates.

What’s Cooking with the Events Recipe for Drupal CMS

When I first heard the vision for Starshot (now Drupal CMS), I knew exactly how I wanted to contribute. For years I have been working on trying to make it easier to quickly build Drupal sites following established best practices. I had been working on a set of modules I called Configuration Kits, but they were conceptually very similar to Recipes, albeit in a simpler (and less flexible) form.

Have you ever wanted to create a plot or graph in your terminal? Okay, maybe you haven’t, but now that you know you can, you want to! Python has the plotext package for plotting in your terminal. However, while that package is amazing all on its own, there is another package called textual-plotext that wraps the plotext package so you can use it in Textual!

In this tutorial, you will learn the basics of creating a plot in your terminal using the textual-plotext package!

Installation

Your first step in your plotting adventure is to install textual-plotext. You can install the package using pip. Open up your terminal and run the following command:

python -m pip install textual-plotext

Pip will install textual-plotext and any dependencies it needs. Once that’s done, you’re ready to start plotting!

Usage

To kick things off, you’ll create a simple Textual application with a scatter chart in it. This example comes from the textual-plotext GitHub repo. You can create a Python file and name it something like scatterplot.py and then add the following code:

from textual.app import App, ComposeResult from textual_plotext import PlotextPlot class ScatterApp(App[None]): def compose(self) -> ComposeResult: yield PlotextPlot() def on_mount(self) -> None: plt = self.query_one(PlotextPlot).plt y = plt.sin() # sinusoidal test signal plt.scatter(y) plt.title("Scatter Plot") # to apply a title if __name__ == "__main__": ScatterApp().run()

When you run this code, you will see the following in your terminal:

Plotext does more than scatterplots though. You can create any of the following:

• Scatter Plot
• Line Plot
• Log Plot
• Stem Plot
• Bar Plots
• Datetime Plots
• Special Plots
• Decorator Plots
• Image Plots
• and more

Let’s look at a bar plot example:

from textual.app import App, ComposeResult from textual_plotext import PlotextPlot class BarChartApp(App[None]): def compose(self) -> ComposeResult: yield PlotextPlot() def on_mount(self) -> None: languages = ["Python", "C++", "PHP", "Ruby", "Julia", "COBOL"] percentages = [14, 36, 11, 8, 7, 4] plt = self.query_one(PlotextPlot).plt y = plt.bar(languages, percentages) plt.scatter(y) plt.title("Programming Languages") # to apply a title if __name__ == "__main__": BarChartApp().run()

The main difference here is that you’ll be calling plt.bar() with some parameters, whereas,  in the previous example, you called plt.sin()with no parameters at all. Of course, you also need some data to plot for this second example. The provided data is all made up.

When you run this example, you will see something like the following:

Isn’t that neat?

Wrapping Up

You can create many other plots with Plotext. Check out their documentation and give some of the other plots a whirl. Have fun and make cool things in your terminal today!

As the Qt 6.8 Beta 3 was released last week, it is a good time to start talking about what's new in the Qt 6.8 release. This blog post introduces one of those things, the new effect nodes available in Qt Quick Effect Maker. Also included is an example application using all of these effects.

We’re introducing the Databricks integration with PyCharm Professional to make it easier for you to process, store, and analyze your data! 

The integration allows you to build your data and AI apps on the Databricks Data Intelligence Platform directly within PyCharm Professional, enhancing the data analytics platform with the powerful Python IDE by JetBrains. It enables you to write code quickly and easily and run it in the cloud without extra configurations, and it offers additional benefits for working with data. 

Read this blog post to learn more about the integration, who it will be useful for, and what benefits it offers.

Install the Databricks plugin Watch the plugin in action What is Databricks?

The Databricks Data Intelligence Platform allows your entire organization to use data and AI. It’s built on a lakehouse to provide an open, unified foundation for all data and governance, and is powered by a Data Intelligence Engine that understands the uniqueness of your data.

What is PyCharm Professional?

PyCharm Professional is a leading IDE for Python and other programming languages. It allows you to write high-quality and efficient code using superior code completion, refactoring capabilities, code inspections, seamless code and project navigation, a debugger, and a wide range of integrations, including Jupyter notebooks, testing frameworks, Git, CI/CD solutions, and more – all available in one place right out of the box.

Who will the integration be useful for? 

Organizations and data professionals using data lakehouses, data lakes, and data warehouses via Databricks will benefit from this integration.

What benefits does the integration bring?

The integration combines the most powerful capabilities of each platform, allowing you to easily build all of your data and AI applications at scale within PyCharm: 

• Use PyCharm to implement software development best practices, which are essential for large codebases, such as source code control, modular code layouts, testing, and more. 
• Databricks enables the use of powerful clusters, allowing you to work on projects too large for a local machine and helping you orchestrate data processing efficiently. 

You can write the code for your pipelines and jobs in PyCharm, then deploy, test, and run it in real time on your Databricks cluster without any additional configurations. 

Let’s dive into more details about what the PyCharm Databricks integration provides.

Connect to your cluster via PyCharm

You can connect directly to the Databricks cluster via PyCharm and monitor the process within the IDE. This allows you to check if the cluster is running, see the results of the current session’s runs, and view process outcomes along with additional details.

Run Python scripts on a remote cluster

In addition, you can run Python scripts on a remote cluster, which is particularly useful for working with big data, and view the results in the IDE.

Run Jupyter notebooks or Python scripts as workflows

Additionally, you can run your notebook or Python scripts as a Databricks workflow and see the output in the console. 

You can see the results of the runs on the Databricks platform, including the runs initiated from PyCharm.

Synchronize project files to the Databricks workspace

The synchronization of project files with the Databricks workspace allows you to access and work with the same files in both PyCharm and Databricks workspaces. You can also schedule your notebooks and scripts and utilize other platform features for projects completed in PyCharm.
