    OpenAI has b=
    een talking to the movie industry's largest studios for
    months, but those=
    talks have yet to produce any deals. Studios are
    reluctant to get into b=
    usiness with an AI company as it may anger the
    labor unions that they wor=
    k with. Screenwriters and actors have been
    urging studios to police tech =
    companies and ensure that their work
    isn't being used illegally. OpenAI f=
    ound a receptive audience among
    some filmmakers when it released its Sora=
    AI video generator early
    last year, but conversations with studios have =
    been more complicated.
    While studios recognize that AI is already changin=
    g how people work,
    they are reluctant to hand over their most valuable as=
    sets to large
    tech firms without receiving a significant payout.=20

    SCIENCE & FUTURISTIC TECHNOLOGY

    WITH GENERATIVE AI=
    , MIT CHEMISTS QUICKLY CALCULATE 3D GENOMIC
    STRUCTURES (7 MINUTE READ) [7=
    ]=20

    MIT chemists have figured out a new method for determining 3D geno=
    me
    structures using generative artificial intelligence. The technique can=

    predict thousands of structures in minutes. It can be used to easily
    s=
    tudy how the 3D organization of the genome affects individual cells'
    gene=
    expression patterns and functions. It could also be used to
    explore how =
    mutations in DNA sequences can cause disease. The model
    and all of the da=
    ta are available on GitHub.=20

    OUR BRAINS ARE SOAKING UP MICROPLASTICS =
    MORE THAN OTHER ORGANS (3
    MINUTE READ) [8]=20

    Microplastics have been=
    detected in human brains at much higher
    concentrations than in other org=
    ans. Much of the plastic appears to be
    smaller than previously thought, w=
    ith some pieces only about two to
    three times the size of a virus. People=
    diagnosed with dementia had up
    to 10 times as much plastic in their brai=
    ns as others, but there is
    not enough evidence to definitively conclude o=
    n cause or effect. It is
    unknown what effect microplastics have on human =
    health, but the
    tiniest pieces can cross the blood-brain barrier.=20

    PROGRAMMING, DESIGN & DATA SCIENCE

    BEEJ'S GUIDE TO=
    GIT (WEBSITE) [9]=20

    Git is a version control system that keeps snapsh=
    ots of source code
    in directory trees. It allows users to make changes an=
    d then commit
    those changes to the source code repository once a feature =
    is ready.
    Git keeps a history of all commits made, so users can look at p=
    revious
    commits whenever required. This page contains a guide to Git that=

    covers the basics and how to use it. It assumes readers have basic
    POS=
    IX shell usage skills and that they are working in a Unix-like
    environmen=
    t.=20

    HOW I USE LLMS AS A STAFF ENGINEER (5 MINUTE READ) [10]=20

    Th=
    is post discusses how a staff engineer from GitHub who worked
    directly on=
    Copilot uses large language models. Large language models
    can be helpful=
    for smart autocomplete, short tactical chains, writing
    use-once-and-thro=
    waway research code, asking questions to learn about
    new topics, last-res=
    ort bug fixes, and proofreading. The technology
    still isn't great for wri=
    ting PR, ADRs, or other technical
    communications. It also isn't great for=
    research in large codebases.=20

    CHAT IS A BAD UI PATTERN FOR DEVELOPMENT TOOLS (3 MINUTE READ) [11]=20

    =
    Coding forces humans to think like machines. While programming has
    become=
    more friendly throughout the decades, we are still just
    translating huma=
    n thoughts into computer instructions. AI was supposed
    to allow plain Eng=
    lish to become a programming language, but it isn't
    suitable for building=
    serious software. Current tools pretend that
    writing software is like ha=
    ving a conversation, but real software
    can't be built without being preci=
    se about requirements. Companies
    need to build tools for real software in=
    stead of toys.=20

    OPENAI HAS UNDERGONE ITS FIRST EVER REBRAND, GIVING F=
    RESH LIFE TO
    CHATGPT INTERACTIONS (14 MINUTE READ) [12]=20

    lack cohesion. The new identity is more organic

    <strong>How I use LLMs as a staff e= ngineer (5 minute read)</strong>

    <span style=3D"font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, V= erdana, sans-serif;">
    This post discusses how a staff enginee=
    r from GitHub who worked directly on Copilot uses large language models. La= rge language models can be helpful for smart autocomplete, short tactical c= hains, writing use-once-and-throwaway research code, asking questions to le= arn about new topics, last-resort bug fixes, and proofreading. The technolo=
    gy still isn't great for writing PR, ADRs, or other technical communication=
    s. It also isn't great for research in large codebases.
