Stable Diffusion Benchmarks: 45 Nvidia, AMD, and Intel GPUs Compared

Stable Diffusion images per minute. Benchmarking 50 GPUs

We’ve benchmarked Stable Diffusion, a popular AI image generator, on the 45 of the latest Nvidia, AMD, and Intel GPUs to see how they stack up. We’ve been poking at Stable Diffusion for over a year now, and while earlier iterations were more difficult to get running — never mind running well — things have improved substantially. Not all AI projects have received the same level of effort as Stable Diffusion, but this should at least provide a fairly insightful look at what the various GPU architectures can manage with AI workloads given proper tuning and effort.

The easiest way to get Stable Diffusion running is via the Automatic1111 webui project. Except, that’s not the full story. Getting things to run on Nvidia GPUs is as simple as downloading, extracting, and running the contents of a single Zip file. But there are still additional steps required to extract improved performance, using the latest TensorRT extensions. Instructions are at that link, and we’ve previous tested Stable Diffusion TensorRT performance against the base model without tuning if you want to see how things have improved over time. Now we’re adding results from all the RTX GPUs, from the RTX 2060 all the way up to the RTX 4090, using the TensorRT optimizations.

For AMD and Intel GPUs, there are forks of the A1111 webui available that focus on DirectML and OpenVINO, respectively. We used these webui OpenVINO instructions to get Arc GPUs running, and these webui DirectML instructions for AMD GPUs. Our understanding, incidentally, is that all three companies have worked with the community in order to tune and improve performance and features.

On Zombie Philosophy

• , , ,

Physics has empiricism. If your physical theory doesn’t make a testable prediction, physicists will make fun of you. Those that do make a prediction are tested and adopted or refuted based on the evidence. Physics is trying to describe things that exist in the physical universe, so physicists have the luxury of just looking at stuff and seeing how it behaves.

Mathematics has rigor. If your mathematical claim can’t be broken down into the language of first order logic or a similar system with clearly defined axioms, mathematicians will make fun of you. Those that can be broken down into their fundamentals are then verified step by step, with no opportunity for sloppy thinking to creep in. Mathematics deals with ontologically simple entities, so it has no need to rely on human intuition or fuzzy high-level concepts in language.

Philosophy has neither of these advantages. That doesn’t mean it’s unimportant; on the contrary, philosophy is what created science in the first place! But without any way of grounding itself in reality, it’s easy for an unscrupulous philosopher to go off the rails. As a result, much of philosophy ends up being people finding justifications for what they already wanted to believe anyway, rather than any serious attempt to derive new knowledge from first principles. (Notice how broad the spread of disagreement is among philosophers on basically every aspect of their field, compared to mathematicians and physicists.)

This is not a big deal when philosophy is a purely academic exercise, but it becomes a problem when people are turning to philosophers for practical advice. In the field of artificial intelligence, things are moving quickly, and people want guidance about what’s to come. Should we consider AI to be a moral patient? Does moral realism imply that advanced AI will automatically prioritize humans’ best interests, or does the is-ought problem prevent that? What do concepts like « intelligence » and « values » actually mean?

Sobre la Gestión del conocimiento en las organizaciones:
Las tres leyes de la dinámica del conocimiento (Debra Amidon)
1. Cuando se comparte conocimiento, este se multiplica.
2. El valor se crea cuando el conocimiento se mueve desde un punto de origen a otro punto en el que existe una oportunidad o necesidad.
3. El apoyo mutuo con conocimiento proporciona la utilización óptima de los recursos, tanto tangibles como intangibles.

Push-button installer of macOS Catalina, Mojave, and High Sierra guests in Virtualbox

Imago voragine.net
• , ,

macos-guest-virtualbox.sh is a Bash script that creates a macOS virtual machine guest on VirtualBox with unmodified macOS installation files downloaded directly from Apple servers.

A default install only requires the user to sit patiently and, less than ten times, press enter when prompted by the script, without interacting with the virtual machine.

Tested on bash and zsh on Cygwin. Works on macOS, CentOS 7, and Windows on x86 CPUs with VT-x or AMD-V. Should work on most modern Linux distros.

macOS Catalina (10.15), Mojave (10.14), and High Sierra (10.13) currently supported.

Why Sam Altman wants to scan two billion eyes

Imago voragine.net
• , , ,

Sam Altman – the executive behind ChatGPT – has scanned the irises of more than two million people with a metal sphere, to prove that they’re human.

The process is simple: you install an application on your mobile phone and receive a QR code. Then, you must allow a metallic sphere to look at you with its eye and generate a “personality test.” The proof is then associated with the QR code and the app becomes a passport called World ID. This also acts as a digital wallet for a cryptocurrency called Worldcoin.

Many shopping centers are already offering this service. But the question is: why would anyone want to submit this personal information?

Traducción con Pods de WordPress y WPML

Imago voragine.net
• , , ,

en el caso de que se estén empleando plugins para el desarrollo de una solución WordPress que no sean compatibles con WPML, por ejemplo PODS, una solución interesante, es duplicar el mismo post o tipo de contenido, que ha sido creado con elementos del plugin incompatible y aprovechar cada versión para cada uno de los idiomas que hemos configurado para nuestro sitio, diferenciando cada post con una nomenclatura, por ejemplo con el diminutivo (_en, _es, _fr) del idioma en el slug o (-EN, -ES, -FR) en el nombre del mismo.

Para que luego WordPress distnga cual de esos bloques o contenidos pertenece al idioma concreto, utilizamos la constante ICL_LANGUAGE_CODE, definida por WPML, que se pueden emplear como parte del nuestro tema, para poder invocar el contenido de un post u otro en dependencia del idioma actual con el que se está navegando en nuestro sitio, idioma almacenado en la constante antes mencionada.

De esta manera un ejemplo podría ser:

How to listen to music from the console using the cmus player on Linux

Imago voragine.net
• ,

We can cycle through the reproduction modes by pressing the m key. The modes define the range of song which are considered in the library view. When using the all from library mode, all the song in the library will be considered. In the artist from library mode the player will consider only the songs in the library which belongs to the same artist of the song which is currently playing. Finally, in the album from library mode, the player will only consider the songs belonging to the same album of the one currently in reproduction.

If the C function is active, as in our case, when cmus finishes reproducing the currently playing song, it will automatically start playing the next one in the list. To toggle this functionality we must press shift+c.

If the R function is active cmus will start again reproducing the group of songs we selected once it reaches the end of the list. For example, if we are using the artist from library mode, once all the songs of the artist are played, the player will start reproducing the artist’s collection from the start. For this function to be effective the C function must also be active. When the S function is active, the player is in shuffle mode, so it will choose random tracks from the library.

When the F function is active the player will always automatically select the current playing song on the list. To be more clear, suppose we have the C function enabled: when the player finishes playing the currently selected song it will start playing the next in the list, but, by default, it will not “select” it (it will not highlight it with the “selection bar”). When the F function is enabled, instead, the two things will always be in sync, and the song currently in reproduction will always be selected automatically.

Entrevista a Chema « Animal » Pérez

¿De dónde sale el apodo de “Animal”?

En mi tercer concierto con los Enemigos íbamos de Zaragoza a Alicante y llegábamos tarde… muy tarde, como pasaba por aquel entonces, era el año 89. Íbamos en la furgoneta, entramos por las calles de Alicante para llegar al garito donde íbamos a tocar y de repente llegamos a una calle muy estrecha de sentido único. Había un R5 aparcado con el culo muy despegado de la acera y no cabíamos, la furgoneta no pasaba, no había forma… El road manager pitando y pitando y allí no salía nadie, y nosotros con una prisa que no veas, agobiados. Total que dije: “yo lo aparto…” me bajé de la furgoneta, cogí el coche por la parte trasera y apoyando la espalda en el cristal con las manos por el paso de rueda de atrás lo llevanté y lo metí en su sitio. Hay que decir que eso lleva una técnica… yo tenía un R5 y solía hacer eso cuando me quedaba mal aparcado, con lo cual ya sabía como hacerlo; no fue cosa del momento. Cuando entré en la furgoneta todos estaban callados mirándome, petrificados de lo que acababan de ver. Llegamos a tiempo a la sala, tocamos y todo salió bien. El viernes siguiente a aquella actuación, creo que fue, hicimos el programa ‘Música Golfa’ de Paco Pérez Bryan de TVE. Nos presentaba él mismo y Paco estaba hablando con Josele sobre el nuevo disco, la nueva incorporación que era el batería y le preguntó como se llamaba… y Josele le dijo: “Animal”. Curiosamente “Animal” era el apodo de un fotógrafo barbudo, con gafas y pelo largo que salía en la serie ‘Lou Grant’ de los años 80 y a mí aquel apodo me encantaba. Pero claro, el problema es que los apodos no los eliges tú, te los ponen logicamente… resulta que años después estoy tocando con Los Enemigos y Josele me presenta en pleno concierto como “Animal” así que a partir de ahí fui “Animal” y lo sigo siendo…

Response: json() method

Imago voragine.net

The json() method of the Response interface takes a Response stream and reads it to completion. It returns a promise which resolves with the result of parsing the body text as JSON.

const myList = document.querySelector("ul");
const myRequest = new Request("products.json");

fetch(myRequest)
  .then((response) => response.json())
  .then((data) => {
    for (const product of data.products) {
      const listItem = document.createElement("li"); 
      listItem.appendChild(document.createElement("strong")).textContent = product.Name; 
      listItem.append(` can be found in ${product.Location}. Cost: `); 
      listItem.appendChild(document.createElement("strong")).textContent = `£${product.Price}`; 
      myList.appendChild(listItem);
    }

EventTarget: addEventListener() method

Imago voragine.net
• , ,

The Function.prototype.bind() method lets you establish a fixed this context for all subsequent calls — bypassing problems where it’s unclear what this will be, depending on the context from which your function was called. Note, however, that you’ll need to keep a reference to the listener around so you can remove it later.

class Something {
  name = "Something Good";
  constructor(element) {
    // bind causes a fixed `this` context to be assigned to `onclick2`
    this.onclick2 = this.onclick2.bind(this);
    element.addEventListener("click", this.onclick1, false);
    element.addEventListener("click", this.onclick2, false); // Trick
  }
  onclick1(event) {
    console.log(this.name); // undefined, as `this` is the element
  }
  onclick2(event) {
    console.log(this.name); // 'Something Good', as `this` is bound to the Something instance
  }
}

const s = new Something(document.body);

Une vie sans Internet

Dans ma famille, il y a un type qui s’appelle Jean-François. Il a 80 ans mais ne les fait pas. J’ai toujours bien aimé le regarder parce qu’il est petit, rond, avec une longue barbe, il ressemble à un personnage de conte de fées. Et puis, il est assez poétique. Il accorde les pianos, travaille le bois, fabrique des meubles, répare des trucs, construit des objets très délicats, comme de petits acrobates en cordes et baguettes qui font de très gracieux mouvements. Dans la famille, on le considère un peu comme un original parce qu’il dit des trucs un peu bizarres parfois, qu’il fait des blagues qu’on ne comprend pas toujours, qu’il ne sait jamais qui est qui. Mais sous ses airs, non seulement il est très habile de ses mains, mais il sait plein de choses, il est toujours au courant de l’actu, il a élevé quatre enfants, il conduit une voiture qui a l’air presque neuve. Bref, Jean-François, il n’a pas l’air très empêché dans la vie.

Et pourtant, il vit complètement en dehors du monde numérique, et même de l’informatique la plus basique. Ca, je l’ai appris dernièrement, au hasard d’une discussion. Au début, ça m’a juste fait marrer, mais ça m’a trotté dans la tête pendant quelques mois. Je me suis dit qu’en parler avec lui, ce serait peut-être le moyen de comprendre plein choses. Déjà, comment on peut vivre aujourd’hui sans internet, sans smartphone ? Mais ce qui m’intéresse aussi, c’est de comprendre pourquoi il vit comme ça ? Manifestement, dans son cas, ce n’est pas un problème économique. Est-ce que c’est un choix ? Est-ce qu’il a décroché un moment et n’a plus été capable de raccrocher les wagons ? Est-ce que ça l’angoisse ? Est-ce qu’il a l’impression de comprendre encore le monde dans lequel il vit ?

Page de La dernière reine

Jean-Marc Rochette explique : « On m’a reproché de faire des histoires virilistes, sans femme ou presque. C’est faux : dans Ailefroide, ma mère, une femme forte, et ma grand-mère sont présentes. Là, j’ai mis au cœur de La dernière reine une femme comme moteur. Dans ce récit, il s’agit d’ailleurs d’un homme sauvé par une femme. Edmond Roux n’existe pas sans elle. Dans les scènes d’amour, c’est une vision inverse des codes habituels de la sexualité qui est présentée. C’est Jeanne qui ausculte Edmond, qui lui demande de se déshabiller, qui lui dit qu’elle le trouve beau et qu’il a un corps magnifique. Elle commence d’ailleurs par soulever le voile qu’il porte pour dissimuler son visage abîmé. C’est d’une sensualité folle. Mais je ne l’ai vue qu’après avoir dessiné. »

Détail de la couverture de La dernière reine

Gueule cassée de 14, Édouard Roux trouve refuge dans l’atelier de la sculptrice animalière Jeanne Sauvage. Elle lui redonne un visage et l’introduit dans le milieu des artistes de Montmartre. En échange, Édouard lui fait découvrir la majesté du plateau du Vercors et l’histoire du dernier ours qu’il a vu tué quand il était enfant. Au cœur du Cirque d’Archiane, il lui dévoile la Dernière Reine et incite Jeanne a créer le chef d’œuvre qui la fera reconnaître.
Dans la veine des grands romans feuilletons du 19e, La Dernière Reine croise les destins du dernier ours du Vercors et d’Édouard Roux gueule cassée de 14.
Comme précédemment dans Le Loup, homme et animal se confrontent dans un récit puissant, mêlant questionnements écologiques, féminisme, histoire d’amour et histoire de l’art.

Email is an essential service in every business, and the effect of a company losing control over their email service is devastating, even if the company has merged or shut down. Sensitive information and documents are often exchanged over emails between clients, colleagues, vendors and service providers due to the convenience. Consequently, if a bad actor takes control of an entire business’s email service, sensitive information can end up in wrong hands.

Inside the online world of people who think they can change their race

Imago voragine.net
• , , ,

Practitioners of “race change to another,” or RCTA, purport to be able to manifest physical changes in their appearance and even their genetics to truly become a different race.

Practitioners of what they call “race change to another,” or RCTA, purport to be able to manifest physical changes in their appearance and even their genetics to become a different race. They tune in to subliminal videos that claim can give them an “East Asian appearance” or “Korean DNA.”

Experts agree race is not genetic. But they contend that even though race is a cultural construct, it is impossible to change your race because of the systemic inequalities inherent to being born into a certain race.

David Freund, a historian of race and politics and an associate professor at the University of Maryland, College Park, corroborates the idea that a “biological race” does not exist. What we know today as “race” is a combination of inherited characteristics and cultural traditions passed down through generations, he said.
