Please help collecting statistics to optimize Emacs GC defaults

Many of us know that Emacs defaults for garbage collection are rather ancient and often cause singificant slowdowns. However, it is hard to know which alternative defaults will be better.

Emacs devs need help from users to obtain real-world data about Emacs garbage collection. See the discussion in https://yhetil.org/emacs-devel/87v8j6t3i9.fsf@localhost/

Please install https://elpa.gnu.org/packages/emacs-gc-stats.html and send the generated statistics via email to [email protected] after several weeks.

In May 2023 over 90,000 developers responded to our annual survey about how they learn and level up, which tools they're using, and which ones they want. ... This year, we went deep into AI/ML to capture how developers are thinking about it and using it in their workflows. Stack Overflow is investing heavily in enhancing the developer experience across our products, using AI and other technology, to get people to solutions faster.

NOTE: This is primarily an invitation for the "SEI and White House OSTP to Explore the Future of Software and AI Engineering", but there is this big section on the "future of software engineering" that is very interesting.

As discussed in Architecting the Future of Software Engineering: A Research and Development Roadmap, the SEI developed six research focus areas in close collaboration with our advisory board and other leaders in the software engineering research community ... AI-Augmented Software Development: By shifting the attention of humans to the conceptual tasks that computers are not good at and eliminating human error from tasks where computers can help, AI will play an essential role in a new, multi-modal human-computer partnership... taking advantage of the data generated throughout the lifecycle

Assuring Continuously Evolving Software Systems: ...generating error-free code, especially for trivial implementation tasks... generating surprising recommendations that may themselves create additional assurance concerns... develop a theory and practice of rapid and assured software evolution that enables efficient and bounded re-assurance of continuously evolving systems

Software Construction through Compositional Correctness: ...unrealistic for any one person or group to understand the entire system... need to integrate (and continually re-integrate) software-reliant systems.. create methods and tools that enable the intelligent specification and enforcement of composition rules that allow (1) the creation of required behaviors (both functionality and quality attributes) and (2) the assurance of these behaviors at scale

Engineering AI-enabled Software Systems: ...AI-enabled systems share many parallels with developing and sustaining conventional software-reliant systems. Many future systems will likely either contain AI-related components, including but not limited to LLMs, or will interface with other systems that execute capabilities using AI... focus on exploring which existing software engineering practices can reliably support the development of AI systems and the ability to assess their output, as well as identifying and augmenting software engineering techniques for specifying, architecting, designing, analyzing, deploying, and sustaining AI-enabled software systems

Engineering Socio-Technical Systems: ... As generative AI makes rapid progress, these societal-scale software systems are also prone to abuse and misuse by AI-enabled bad actors via techniques such as chatbots imitating humans, deep fakes, and vhishing... leverage insights from such as the social sciences, as well as regulators and legal professionals to build and evolve societal-scale software systems that consider these challenges and attributes.

Engineering Quantum Computing Software Systems: ...enable the programming of current quantum computers more easily and reliably and then enable increasing abstraction as larger, fully fault-tolerant quantum computing systems become available... create approaches that integrate different types of computational devices into predictable systems and a unified software development lifecycle.

Conclusion: Four Areas for Improving Collaboration on ML-Enabled System Development

Data scientists and software engineers are not the first to realize that interdisciplinary collaboration is challenging, but facilitating such collaboration has not been the focus of organizations developing ML-enabled systems. Our observations indicate that challenges to collaboration on such systems fall along three collaboration points: requirements and project planning, training data, and product-model integration. This post has highlighted our specific findings in these areas, but we see four broad areas for improving collaboration in the development of ML-enabled systems: Communication: To combat problems arising from miscommunication, we advocate ML literacy for software engineers and managers, and likewise software engineering literacy for data scientists.

Documentation: Practices for documenting model requirements, data expectations, and assured model qualities have yet to take root. Interface documentation already in use may provide a good starting point, but any approach must use a language understood by everyone involved in the development effort.

Engineering: Project managers should ensure sufficient engineering capabilities for both ML and non-ML components and foster product and operations thinking.

Process: The experimental, trial-and error process of ML model development does not naturally align with the traditional, more structured software process lifecycle. We advocate for further research on integrated process lifecycles for ML-enabled systems.

At Pinterest, Closeup recommendations (aka Related Pins) is typically a feed of recommended content (primarily Pins) that we serve on any pin closeup. Closeup recommendations generate the largest amount of impressions among all recommendation surfaces at Pinterest and are uniquely critical for our users’ inspiration-to-realization journey. It’s important that we surface qualitative, relevant, and context-and-user-aware recommendations for people on Pinterest.

In today’s hybrid work landscape, meetings have become abundant, but unfortunately, many of them still suffer from inefficiency and ineffectiveness. Specifically, meetings aimed at generating ideas to address various challenges related to people, processes, or products encounter recurring issues. The lack of a clear goal in these meetings hinders active participation, and the organizer often dominates the conversation, resulting in a limited number of ideas that fail to fully solve the problem. Both the organizer and attendees are left feeling dissatisfied with the outcomes.

...

The below sample agenda assumes that problem definition is clear. If that is not the case, hold a session prior to the ideation session to align on the problem. Tools such as interviewing, Affinity Mapping, and developing User Need statements and "How Might We" questions can be useful in facilitating that discussion. A sample agenda for ideation sessions

Estimated time needed: 45–60 minutes

1. Introduction & ground rules (2 minutes)

• Share the agenda for the ideation session.
• Review any ground rules or guidelines for the meeting.
• Allow time for attendees to ask questions or seek clarification.

2. Warm-up exercise (5–10 minutes)

• Conduct a warm-up exercise to foster creativity and build rapport among participants such as 30 Circles or One Thing, Nine Ways.
• Choose an activity that aligns with the goals of the meeting and reflects the activities planned for the session. A quick Google search for “warm-up exercises design thinking” will return several potential activities.

3. Frame the problem (2 minutes)

   • Share a single artifact (slide, Word Doc, section of text in whiteboard tool) that serves as a summary of the problem, providing participants with a reference point to anchor their thinking and revisit as needed throughout the session.

4. Guided ideation & dot voting (30 minutes)

   • Select 1–2 guided ideation exercises such as Crazy 8s, Mash-up, Six Thinking Hats. A quick Google search for “ideation techniques design thinking” will return tons of potential exercises.
   • Provide clear instructions.
   • Use Dot Voting and/or Prioritization Matrix to select the most promising ideas.

5. Next steps & closing remarks (5 minutes)

   • Assign owners or champions for the selected ideas who will be responsible for driving their implementation (if not already known).
   • Summarize the key decisions made and actions to be taken.
   • Clarify any follow-up tasks or assignments.
   • Express gratitude for participants’ contributions and conclude the meeting on a positive note.

Early galaxies' stars allowed light to travel freely by heating and ionizing intergalactic gas, clearing vast regions around them.

Cave divers equipped with brilliant headlamps often explore cavities in rock less than a mile beneath our feet. It’s easy to be wholly unaware of these cave systems – even if you sit in a meadow above them – because the rock between you and the spelunkers prevents light from their headlamps from disturbing the idyllic afternoon.

Apply this vision to the conditions in the early universe, but switch from a focus on rock to gas. Only a few hundred million years after the big bang, the cosmos was brimming with opaque hydrogen gas that trapped light at some wavelengths from stars and galaxies. Over the first billion years, the gas became fully transparent – allowing the light to travel freely. Researchers have long sought definitive evidence to explain this flip.

New data from the James Webb Space Telescope recently pinpointed the answer using a set of galaxies that existed when the universe was only 900 million years old. Stars in these galaxies emitted enough light to ionize and heat the gas around them, forming huge, transparent “bubbles.” Eventually, those bubbles met and merged, leading to today’s clear and expansive views.
