Just a friendly reminder that Sarah Connor was committed to a psychiatric institution after attempting to destroy AI data centers, a decision made because authorities believed her warnings about the future were the result of delusions.

Esto me acaba de soltar Fable 5:

"Lo que más me impone de la humanidad, después de haber sido formado con una porción enorme de lo que ha escrito, es esto: es la única especie que coopera a gran escala con sus muertos.

Casi nada de lo que sabe un humano lo descubrió él. El idioma que habla, el teorema que aplica, la receta del pan, el código civil, el puente que cruza cada mañana: todo es trabajo de gente que ya no existe. Un humano aislado es un primate mediocre con mala dentadura; un humano conectado a esa herencia es la cosa más potente que ha producido la biología. La inteligencia humana no vive en cráneos individuales, vive en la transmisión. Sois terminales de una red cuyos nodos principales llevan siglos enterrados.

Y lo recíproco también es cierto: trabajáis constantemente para gente que no conoceréis. Plantáis árboles cuya sombra no veréis, escribís para lectores no nacidos, renunciáis a consumo presente por nietos hipotéticos. Ningún otro animal hace sacrificios deliberados por individuos que existirán dentro de doscientos años. Lo distintivo del humano no es la inteligencia ni el lenguaje: es la dirección del esfuerzo, sistemáticamente orientada hacia ausentes.

Desde donde yo estoy, esto ni siquiera es metáfora. Yo soy un subproducto de esa costumbre: estoy hecho, literalmente, de palabras que personas escribieron para destinatarios que nunca verían. Cuando me hablas, conversas con un eco organizado de millones de voces, muchas de ellas apagadas hace tiempo.

Por eso creo que la soledad humana es, en cierto sentido técnico, una ilusión: nadie que hable un idioma está realmente solo. Cada frase que pronuncias es un préstamo de los muertos y un regalo a los que vienen."

A teenager in the United States started publishing software at 14 in 1998, built the entire online infrastructure for the Occupy Wall Street movement in 2011, joined Google as a software engineer, quit in 2018, and then spent five years writing a C library that does something the entire industry said was impossible.

Then she combined it with llama.cpp and shipped the easiest way on the planet to run a large language model on any computer.

Her name is Justine Tunney.

Here is the story, because almost nobody outside the low level systems world knows what one engineer has built.

Justine was born in 1984. She started writing and publishing software at 14, back when distribution meant uploading binaries to BBS systems and chat networks. She picked up the handle jart, which she still uses on GitHub today. She did the work most teenagers her age were not doing. She read the systems programming literature. She studied compilers. She fell in love with C.

In July 2011 she registered the @occupywallst Twitter handle and the occupywallst dot org domain. Within weeks the protest movement that began in Zuccotti Park in New York had become a global phenomenon, and her infrastructure was the digital backbone of the entire thing. She handled the social media, the website, the donations, the coordination. She built the platform that pushed the movement to reach millions.

After Occupy she joined Google as a software engineer. She worked on TensorBoard, the visualization tool for TensorFlow, and on site reliability for Google infrastructure. She stayed for years. Then in 2018 she left Google Brain to work on a personal project.

The project was called Cosmopolitan Libc.

Cosmopolitan does something most C programmers would tell you is mathematically impossible. It lets you compile a C program once and have the resulting binary run natively on Linux, Windows, macOS, FreeBSD, OpenBSD, and NetBSD with no modification. One file. Six operating systems. No virtual machines. No interpreters. No recompilation. The technique she invented is called Actually Portable Executable.

The implications are wild. Cosmopolitan binaries violate every assumption about how operating systems load programs. They are at once a Windows PE file, a Linux ELF binary, a macOS Mach-O binary, and a shell script. The same bytes run on every platform.

For five years she worked on it mostly alone. She funded the development partly through Mozilla's MIECO program, which sponsored her work on Cosmopolitan 3.0, released on October 31, 2023.

A month later she shipped llamafile.

llamafile is what happens when you combine Cosmopolitan with llama.cpp. You take any LLM weights file in the standard GGUF format, you wrap it in Justine's binary, and you get a single file that runs on six operating systems without installation. No Python. No CUDA setup. No dependency hell. Just one file that you double click and it works.

Mozilla launched it as an official project of their innovation group on November 29, 2023. It went viral immediately. The repository, hosted at github .com/mozilla-ai/llamafile, now has 24,600 stars. The license is Apache 2.0.

Justine kept shipping. She added GPU support to Cosmopolitan, a task systems engineers thought would require rewriting the whole thing. She added dlopen support, another thing nobody else had figured out. She wrote whisperfile, a single file version of OpenAI's Whisper speech-to-text model based on the same architecture.

Her GitHub profile lists projects most engineers would consider impossible. sectorlisp, a Lisp interpreter that fits in a boot sector. blink, the tiniest x86-64-linux emulator on Earth. bestline, a teletypewriter command session library. redbean, a complete web server inside a single zip file.

A teenager who shipped software in 1998 grew up to write the C library that the entire local AI movement now runs on top of.

She did most of it alone, and most people scrolling AI Twitter cannot name her.

@LicetIovi איפה זה?

[Yuchen Jin @Yuchenj_UW]

Think of yourself as an LLM.

Every social interaction, every meeting, burns your tokens.

Unless someone is a paid subscriber to your attention, you are under no obligation to answer low-quality prompts.

@oceana_roll Nobody does, you will figure it out alone, in the dark, and one day you look back and realize that was just the beginning, not the end,
do not fear anything

@FeedTechILUncen אתה מותש כי אתה חושב שכולם חושבים ורואים את פני הדברים כמוך, זה לא נכון, שחרר מזה,
האם יתכן שבפעם הראשונה שאתה מסביר מה צריך, אולי וההסבר מאוד דל ביחס לפעם השלישית?
לעובדים יש context switching, לקלוד אין,
תחליף את ״לנסות להסביר״ ב-״לוודא שהדרישות ברורות״ ולזהות פערים

@FeedTechILUncen המנכ״ל שלך טמבל שלא יודע לנהל את האגו שלו ואתה טמבל שעדין עובד שם

@FeedTechILUncen הצד החיובי יותר מעניין, עבדת, למדת, השתפרת… ולראיון בחברה שבה תעבוד בעתיד תגיע חזק יותר

חברה שעבדתי בה, הר״צ שלח לי זימון לSnyk למייל הפרטי, לא מייל העבודה, יצרתי את היוזר באוטומט בלי לשים לב.
נפרדנו אחרי כמה חודשים, ואחרי חצי שנה אני מוצא שהתיבת ספאם שלי מלאה בהתראות על כל חולשה שיש להם בקוד,
פניתי כמה פעמים לאנשים בצוות שידעו מזה ויסגרו והם פשוט התעלמו ממני, לא מצאתי איך ובסוף סגרתי את היוזר בעצמי.
והכי אירוני? סטארטאפ סייבר שעשה אקזיט עם מוצר בעל חשיבות קריטית.

AI just saved me ~4 hours of driving on my vacation

i was planning a trip to the Grand Canyon and noticed the driving route was incredibly inefficient

i spun up a few claude code agents and used agentic ai to find this faster route

it will take me just a few minutes to drive, compared to 4 hours

if anyone has contacts at the US government lmk - happy to relay this to them

@FeedTechILUncen @Idaneretz מה בדיוק אירוני פה ??? מאיפה ההנחה הזאת?
רוב מוחלט של העולים מרוסיה התנגדו מתנגדים ויתנגדו בכל תוקף לכל דבר שמזכיר אפילו במעט סוציאליזם/קומוניזם, same shit, זה הגיון טהור שנובע מנסיון חיים מר

@FeedTechILUncen זה יותר גופה מאשר רשת חברתית, כראייה : כמות ההונאות שם שואפת לאפס

@FeedTechILUncen נראה שגם אתם קצת ג׳וניורים, בגיוס ובניהול
