Fallback Tab Dragging for Ozone/Wayland

by Max Ihlenfeldt

Date: 2023/06/05 12:00

Dragging tabs out of and back into Chromium windows doesn’t work on Wayland as on other platforms due to protocol restrictions. There already is a protocol extension that makes regular tab dragging possible, but it requires support from the Wayland compositor. Until all major compositors implement this extension, we need some form of fallback tab dragging that always works.

Unfortunately, to be able to run automated tests against this new tab dragging implementation, we need to fix some long-standing issues with how these tests are run on Wayland - time for another new protocol extension!

JavaScript Modules: Past, Present, and Future

For decades, JavaScript developers have relied on a multitude of module systems to organize and share code. But in 2015, ECMAScript finally introduced built-in standard semantics for modules, providing a long-awaited solution for the language. While ECMAScript modules have quickly become a popular format for writing code, most published code is still compiled to a single bundle or to a legacy module system.

The TC39 committee is actively exploring this design space: are there any missing functionalities compared to previous systems? Do JavaScript developers need any capabilities that the language does not currently provide? What problems do ECMAScript modules currently cause?

Kotlin — is a modern, cross-platform, statically typed, general-purpose programming language developed by JetBrains. It targets JVM, including Android; JS; native platforms via LLVM, including iOS; and Wasm (added recently).

WebAssembly aka Wasm — You know…

Kotlin/Wasm — is the new target and toolchain in the Kotlin family. It has a few special properties:

  • It compiles to Wasm directly without any additional layers, to compile as fast as possible, including incrementally in the future.
  • It uses experimental/fresh proposals like GC, Typed Function References, Exception Handling, and Stringref.

In this talk, we will look deep inside the internal details of the Kotlin/Wasm technology stack and, look at how the Kotlin code is compiled into WebAssembly, look in-depth at the generated code and its structure. We will discuss how the Kotlin/Wasm compiler handles the language features of Kotlin, such as classes, virtual and interface calls, coroutines, and others using fresh and experimental proposals like GC, Exception Handling, Typed Function References.

The talk targets developers interested in the internals of Kotlin/Wasm and wants to have a deeper understanding of how Kotlin or similar languages could be compiled to Wasm, what is brought by mentioned/used proposals and how they could be helpful to other languages targeting WebAssembly.

Servo is a web engine written in Rust. After parts of it were integrated into Mozilla Firefox, the project became independent but dormant in 2020. This year, with renewed interest in using it as a standalone embeddable engine, Servo is returning to active development.

This talk will go over the work we’ve done so far and our plans for the rest of 2023, particularly in Servo’s layout system, as well as how you can help.

Date: 2023/06/05 16:30

Video | Slides

Ladybird is a new browser (and engine) built completely from scratch. It was originally only usable on SerenityOS, but it’s now expanded into its own cross-platform browser.

This talk will tell the story of Ladybird, starting from nothing in 2019, to where we are today, and share some of the challenges we’ve faced along the way.

I will also give an architectural overview of the engine.

Covid rules

The Web Engines Hackfest welcomes the web community back to in-person events, we continue to prioritize the safety of our participants and staff.

The Web Engines Hackfest organizers continuously monitor local guidelines and regulations related to COVID-19. The changeable nature of the pandemic means that regular updates to this policy may be necessary. We will inform registered participants about any substantial changes to this document.

By attending, you agree to abide by applicable Spanish regulations for indoor activities and the Web Engines Hackfest health & safety rules, and to conduct yourself in accordance with all provided instructions. This will include, but is not limited to:

  • refraining from coming to the event if you have COVID-19 or its symptoms, or if you are required to be in self-isolation or quarantine by COVID-19 regulations in Spain or at the location you are travelling from;
  • complying with the prevailing mask-wearing policy communicated at the event; Even if when regulations have removed the obligation to wear masks, the organization establishes masks as recommended indoors;

💡
Notes

  • Usual timetables. Lunch time: 13:00 - 15:30. Dinner time: 20:30 - 22:30. Note that you won't be able to find a restaurant open for lunch at 12:00 or for dinner at 18:00, neither at 19:00; thus you might want to start your day a bit "later" than usual. Main reason behind this is that A Coruña is in the same timezone than central Europe, and sunrise and sunset times are somehow shifted with regard to common standards in other parts of the world.
  • Language. The official languages in A Coruña are Galician and Spanish. Not everybody is able to understand or speak English (in the bus, taxi, hotel, etc). The Web Engines Hackfest is run in English.
  • Climate. A Coruña has a climate heavily moderated by the Atlantic Ocean. Average temperatures are around 10ºC (51ºF) in winter and 19ºC (66ºF) during summer. (See more info at Wikipedia).
  • Tourism. Tourism A Coruña website.

Igalia logo

Code Of Conduct

Igalia is a project which attempts to make space for equality within a system that is highly unequal. In order to do this, we must counter the structural discrimination that surrounds us in the world and, in particular, in our industry. Our desire is expressed through our foundational principles, our internal processes, and guidelines for how we treat each other. The ultimate goal of the code of conduct is to keep Igalia welcoming for all those who interact with us in good faith and to be a positive and fulfilling influence in the lives of the people within our community.

This code of conduct has three sections. In the first section, we present the ideals we believe should underlie interactions within Igalia. In the second section, we describe types of unacceptable behavior. Finally, in the third section, we describe how to report problems, so that we can take steps to ensure that Igalia remains both safe and healthy.

This policy applies in all of the following contexts:

  • The Igalia offices
  • All internal and external meetings including assemblies and the partners council
  • All mailing lists, bug trackers, wikis, and all other online services
  • Igalia sponsored social gatherings such as summits
  • Igalia hosted conferences, hackathons, and other public and private events
  • At all times where a person is acting as a representative of Igalia, including sponsored external events, communities, or using a company e-mail address

Expected Behavior

Be Respectful and Kind

Always assume that others are competent and trying to do their best. Look out for one another and offer help when it is appropriate and welcome. The words you choose are important, so choose them carefully. Be aware that words and imagery have different meanings across countries, cultures, and communities. If you are unsure whether something is appropriate, it is better to keep it to yourself. Be quick to apologize and learn from your mistakes.

Include Everyone

Encourage all voices. Amplify new points of view and listen actively. If you find yourself dominating a discussion, it is especially important to step back and make room for other voices. When repeating ideas and suggestions, give credit to the person who introduced them. Be aware of the amount of time taken up by the dominant members of the group. When it is possible, make sure there are alternative ways to contribute.

Seek Understanding and Consensus

Discussion and debate are essential to Igalia, but we have to remember that we are not trying to “win” disagreements. Always try to encourage constructive discussions and inclusive thinking so that we are working with a wide range of perspectives. At the same time, reject intolerance and the dehumanization of others.

Speak Up

The responsibility for maintaining a safe environment is shared among all of us. If you think something violates the code of conduct, say something.

Unacceptable Behavior

  • Unwelcome, offensive or hurtful comments or jokes related to age, gender, gender identity and expression, sexual orientation, disability, illnesses, mental illness, neuro(a)typicality, physical appearance, body size, race, religion, national origin, nationality, ancestry, or pregnancy
  • Unwelcome, offensive, or hurtful comments or jokes regarding a person’s lifestyle choices and practices
  • Deliberate misgendering, use of “dead” or rejected names, or use of inappropriate nicknames
  • Gratuitous or off-topic sexual images or behavior, non-consensual physical contact and simulated physical contact, or any other type of unwelcome sexual attention
  • Violence, threats of violence, or incitement of violence, including encouraging others to commit self-harm
  • Deliberate intimidation or the sabotage of work
  • Stalking or unwelcome photography, recording, or logging of online activity
  • Sustained disruption of discussion
  • A pattern of inappropriate social contact, such as requesting/assuming inappropriate levels of intimacy with others
  • Deliberate “outing” of any aspect of a person’s identity without their consent except as necessary to protect vulnerable people from intentional abuse
  • Publication of private and personal (unrelated to work) communication, except when it is used as evidence of a code of conduct violation
  • Retaliation for reporting a code of conduct violation

It is impossible to list all types of unacceptable behavior, but a general rule is that conduct committed in bad faith, which causes harm or distress, or after requests to stop is unacceptable. This includes actions taken without malice. When in doubt, take responsibility for your actions, apologize, and move on. Finally, reporting a violation of the code of conduct does not ever violate the code of conduct.

Reporting

There are several ways that you can report behavior that makes you or others feel unsafe, unwelcome, or excluded. These include:

Emails sent to conduct@igalia.com are received by:

  • Andy Wingo
  • Brenna Brown
  • Germán Poo-Caamaño
  • Ioanna Dimitriou
  • Javier Moran
  • Abhijeet Kandalkar

For urgent issues, you may also call +34 951 204 844 and then enter the PIN 1818 followed by the hash sign (#). This will call Javier Moran, Andy Wingo and Ioanna Dimitriou.

People reported as violating the code of conduct will not take part in the process of handling that report. After the report, immediate action will be taken to ensure the safety and well-being of those involved.

Potential consequences of unacceptable behaviour:

  • Removal from an event
  • Temporary removal from Igalia services or locations
  • Permanent removal from Igalia services or locations
  • Termination of employment
