“It will have zero income tax forever, zero capital gains tax. Invest here and make all the money you want. We’re fine,” Bukele said.

This announcement closed “Bitcoin Week,” a large Bitcoin conference that drew hundreds of foreign investors. The tax-free, “techy,” and ecological Bitcoin City — the first of its kind — will be funded by Bitcoin bonds and powered by geothermal energy from a nearby volcano. Crypto mining, the process of creating new bitcoin through intensive cryptographic puzzles, is a notoriously energy-intensive process that has been criticized for increasing global emission rates in vulnerable areas.

Pros of No-Code Platforms

  • An immediate solution to problems you have in terms of website development because you will be able to create software solutions without having to hire expert programmers.
  • Regardless of your degree, career, or position in a business, you can now build a website by yourself that will add value to your craft or business.
  • Building a website is faster and cheaper. Hiring developers will cost you a lot of money and with no-code, you will be able to cut the cost.
  • It will save you months and months of working since you can now build a website straight away without the need to code.
  • You will have creative freedom on what you want to add to your website since the process is more visual.
  • Obviously, with no-code, web developers will have less on their plates and can focus more on streamlining processes or creating new innovations.

Cons of No-Code Platforms

  • Security breaches with no-code are unavoidable, and once the platform you are using is affected by this factor, your website will be compromised as well.
  • You don’t have the full authority with using no-code networks, so basically you are taking a risk in using such platforms.
  • You will not be able to customize software using the no-code platform.
  • You have to adapt your business process based on the capability feature of the no-code network or platform you are using.

La lista TOP500 se publica dos veces al año y registra los supercomputadores más potentes del año. Solo ha habido un cambio en los diez primeros puestos, y es uno curioso y con un poco de sorna.

Se trata de la llegada  la lista del supercomputador Voyager-EUS2, que ha desarrollado Microsoft Azure y que cuenta con una potencia de 30 petaflops por segundo. Todo estupendo, pero lo realmente curioso es que el supercomputador de Microsoft no funciona con Windows, sino con Linux.

Captura de pantalla de The true size of Africa

The whole point being made was that we all have been taught geography mainly based on the Mercator projection – as the background in daily television news, the cover of my school atlas, in general the ubiquitous depiction of the planet.

But the basic fact is that a three-dimensional sphere being shown as a single two-dimensional flat image will always be subject to a conversion loss: something has to give…

The reason why Mercator was such an important advance is simple: on it one can draw straight lines to account for travel routes – in the days of the gigantic merchant fleets and naval battles an immensely valuable attribute.

Captura de pantall de «Corporate Memphis»: ¿Por qué todas las webs parecen iguales?

…decenas de revistas, cuentos, webs y aplicaciones comerciales con una estética similar a la de la ilustración que decora este artículo. A ese estilo se le conoce como «Alegria» o «Corporate Memphis». Es un producto de la precarización y la devaluación del trabajo y tiene decenas de variantes y versiones, todas igualmente exánimes y repetitivas.

El resultado es un cambio cualitativo. Cualquiera puede hacer una ilustración dentro de los códigos visuales del «Corporate Memphis». Ya no es solo que el ilustrador -uno de los últimos artesanos- se haya proletarizado, ni siquiera que una vez proletarizado haya sido expulsado de la oficina y se haya precarizado al extremo vendiendo horas de trabajo en una plataforma. Ahora el ilustrador como tal es ya innecesario.

La automatización combinatoria de un código estándar de imágenes pre-diseñadas permitirá que ilustrar se convierta en una tarea más del desarrollador web. Una entre otras muchas que ya se han automatizado o están en camino de hacerlo. Porque el desarrollador es el primero que ha sufrido la estandarización y procedimentación automatizada de su trabajo. Ahora, Inteligencia Artificial mediante, está siendo alienado incluso de la algoritmia.

The Trojan Room coffee pot was a coffee machine located in the Computer Laboratory of the University of Cambridge, England. Put on the Internet in 1991 by Quentin Stafford-Fraser and Paul Jardetzky, it was migrated to the web in 1993 becoming the world’s first webcam.

To save people working in the building the disappointment of finding the coffee machine empty after making the trip to the room, a camera was set up providing a live picture of the coffee pot to all desktop computers on the office network. After the camera was connected to the Internet a few years later, the coffee pot gained international notoriety as a feature of the fledgling World Wide Web, until it was retired in 2001.

The tricky bit, as a new study called An Empirical Study of C++ Vulnerabilities in Crowd-Sourced Code Examples, is working out which code is OK and which isn’t.

After analysing real code from Stack Overflow, the researchers found a small but still significant number of examples where this happened over a 10-year period to 2018.

The team reviewed 72,483 C++ code snippets for weaknesses defined by the industry Common Weakness Enumeration (CWE) guidelines, finding 69 representing 29 different types of security flaw, most often CWE-150 (‘Improper neutralization of space, meta, or control sequence’).

I’d be fascinated to see a study that compared cutting and pasting code – which carries the small risk of copying and pasting security errors – with coders who don’t copy and paste code and solve unfamiliar problems by always writing their own solution.

Solving the problem yourself carries three possible penalties: #1 it will take longer; #2 there is a good chance that the code (which solves a problem the developer is not well versed in solving) will make it in to the world without ever being reviewed by another person; and #3 if it does go unreviewed, there is a good chance the developer will never learn of their mistake and could well end up repeating it, even cutting and pasting it, into other projects.

What can we do when faced with a world where people lie as a way of shaping the world to their own ends? First, we have to get smart. Disinformation – the conscious, intentional spreading of false information – is not an accident. It’s a strategy. When we encounter information that is surprising, unsettling, or even a little too comfortable, we need to ask ourselves a set of questions: How does the author know this is true? What is s/he trying to persuade me of? Who benefits if I believe this to be true? How can I check this information against other sources I trust?

…disinformation wants to keep us powerless, fighting to assert that’s true rather than challenging those who are in power.

…a boom in conservative Christian schooling, driven nationwide by a combination of pandemic frustrations and rising parental anxieties around how schools handle education on issues including race and the rights of transgender students.

When the pandemic swept across the country in the spring of 2020, many parents turned to home-schooling.

Others wanted or needed to have their children in physical classrooms. In many parts of the country, private schools stayed open even as public schools moved largely online. Because many parents were working from home, they got a historically intimate look at their children’s online classes — leading to what some advocates for evangelical schools call “the Zoom factor.”

More significant, said Mr. Laats, are the words that conservative schools do not use, like “inclusion” and “diversity,” in contrast with a growing number of public and private schools. About 68 percent of students at conservative Christian private schools are white, according to the Education Department, a figure that is comparable to other categories of private schools but significantly higher than public schools.

If many conservative Protestant schools in the 1960s and 1970s were founded to keep white children away from certain people, then the goal today is keeping children away from certain ideas, said J. Russell Hawkins, a professor of humanities and history at Indiana Wesleyan University. “But the ideas being avoided are still having to do with race,” he said.

Deana Wright enrolled her children in Smith Mountain Lake in July, soon after speaking at a school board meeting in Franklin County. She and her husband did not want their children to keep wearing masks in school, and she had also started reading about what her district was teaching about race. She was “shocked” to come across terms like “cultural competency” and “educational equity” — euphemisms, as she saw it, for critical race theory.

“We’re just so grateful that the Christian academy is here,” she said.

Este material se concibe como una guía con pasos básicos para llevar adelante un proceso de mapeo junto a las y los estudiantes y a partir de algunas ideas y recomendaciones que puedan ser retomadas, ampliadas y mejoradas a partir de la experiencia, y de las temáticas y situaciones que se vayan dando en cada uno de los espacios educativos.

Al día siguiente, la ciudad amanece en llamas con las iglesias grafiteadas: “Lxs negrxs tenemos todo el derecho de incendiar un país que construímos gratis”, citando un tweet de @solomongeorgio quien hablaba sobre la protestas por el asesinato de George Floyd en 2020. Al igual que ese cuadro del Prado, este país ha sido construido por cuerpos negros e indígenas que garantizaron el Estado de bienestar de la blanquitud española. “We don’t choose this future”.

Fantasear no significa olvidar, significa reelaborar las narrativas del dolor. Retornar lo arrancado. Devolver lo robado. España es especialista en devoluciones en caliente, estrategia política del sistema de control migratorio que implica la expulsión y devolución de personas migrantes en el instante en el que atraviesan la frontera del Estado. España devuelve a los cuerpos “que no pertenecen” a este territorio, pero aún no devuelve todo lo que no pertenece a este territorio.

El tiempo postpandémico no existe para nosotrxs porque hemos vivido desde hace siglos en este mundo pandémico antinegro, antiindígena y antitrans. Nosotrxs sabemos que “there are black people in the future” (Alisha B. Wormsley) porque “el amor y la libertad negra residen más allá del cuerpo” (Walidah Imarisha: Rewriting the Future: Using Science Fiction to Re-Envision Justice, 2015). No hay espacio o tiempo que nos contenga, no hay Museo que nos encarcele porque siempre nos fugaremos.

Ibai Llanos y Gerard Piqué han liderado un evento donde 31 hombres y una mujer de diferentes países compiten para ganar el Mundial de Globos. ¿Cómo se ha convertido un vídeo viral de un juego casero en un evento mediático que ha congregado a marcas y a miles de personas?

El evento contó con el apoyo de numerosas marcas comerciales y los datos de audiencia son bastante llamativos: la emisión de Twitch asciende en estos momentos a más de 8,5 millones de visualizaciones y casi 500.000 espectadores de media durante todo el streaming. El peruano Francesco de la Cruz se impuso en la final al alemán Jan Spiess. El presidente de Perú felicitó por Twitter al ganador. La cuenta de los JJOO en español también se hizo eco. Y hasta la BBC ha publicado un artículo sobre el tema. Un éxito.

We are allowed to map certain facts from reference imagery in news articles etc.. -though this technically depends on where you are from-. You have to

  1. be fairly certain of the position of each object. They can be a few meters off, but you shouldn’t haphazardly map them.

  2. select sources which are reliable and mention them in your changeset sources or alternatively using the source and source:date tags.

  3. make sure you’re using the right imagery and (if any) offset. This can be adjusted in the editor’s layer menu (in iD, this is located in the right sidebar).

  4. be careful if/when touching existing objects. (You may want to contact the local community, if there is one, to discuss whether they want to map the event to begin with); This may change/remove objects on the map 1) ways which are used for routing 2) areas, such as buildings, or POIs which may be of interest for humanitarian aid.
    You will have to use the proper Lifecycle tags (in combination with area=yes where needed).

  5. be sure you know how to map with multipolygons where needed.

  6. as always, look on the wiki for tags and ask the community if you need help mapping.

Madlyn, que no ha respondido a este diario, dispone un alquiler adaptado al perfil de los nuevos inquilinos: pagando un poco más al mes, la inmobiliaria oferta limpieza de las casas, cambio de sábanas, cuidado de plantas, paseo de perros… Todos ellos servicios ideados para un nuevo vecino, de entre 30 y 40 años, que aterriza desde otras zonas en busca de ubicación y una sensación de autenticidad edulcorada.

A diferencia de Malasaña o Lavapiés, totalmente transformados en parques temáticos para ‘millennials’, en Puerta del Ángel el proceso gentrificador acaba de empezar y avanza calle a calle, como la lava de un volcán. El viejo y el nuevo barrio conviven a pocos pasos; así, mientras unos degustan cervezas artesanas al sol de la plaza, a tres portales de distancia todavía hay vecinos que se acercan a la esquina donde unos colombianos abatieron a tiros al ‘Niño Sáez’, vecino del barrio y uno de los mayores butroneros de la historia de España, para dejarle flores frescas. Alguien escribió «Sáez eterno» en la pared y el ayuntamiento lo cubrió inmediatamente. Aún puede leerse con un determinado tipo de luz.

The shortages have drawn comparisons to the global energy crises of the 1970s, when an OPEC oil embargo led to widespread shortages. But unlike then, the current shortage is not one of fuel but of trained drivers to deliver it.

Truck drivers tend to be older, and they are retiring. At the same time, driver trainees are facing delays in getting licensed because of the pandemic. Transport companies have reported raising wages for truck drivers by 25 percent or more this year to retain them.

Britain’s withdrawal from the European Union has made labor shortages worse, but it’s not the sole cause. The Road Haulage Association, a trade association of road transport operators, estimates that Britain is facing a shortfall of 100,000 drivers. About 20 percent of those are drivers who left Britain after it voted to leave the European Union.

“As soon as a tanker arrives at a filling station, people on social media are advising that a tanker has arrived, and then it’s like bees to a honey pot. Everyone flocks there,” Mr. Madderson said. “Within a few hours it is out again.”

OpenStreetMap offers many possibilities for creating high resolution paper maps. Unlike commercial map services such as Mapquest and Google Maps, there are only a few restrictions on what you can do with OSM images.

GUI written in Python to parse OSM (OpenStreetMap) files and render them onscreen. Layers may be toggled on/off and drawing may be customized.

This program allows a user to render OSM files within the GUI. The GUI enables the user to easily modify which layers are visible and the style of these layers.

The program exports maps as images.

a process by which you can generate your own custom-made stylized maps. A stylized map is a map where the user can specify which data layers are visualized, as well as define the style with which each layer is visualized. I will first describe the process through which you can write software to stylize maps, followed by an example of the Python software I wrote to perform this task.

Choose your region

The region is specified by a bounding box, which consists of a minimum and maximum latitude and longitude. Choose as small a region as will be useful to you, since larger regions will result in larger data files, longer download times, and heavier load on the server. The server may reject your region if it is larger than 1/4 degree in either dimension. When you’re first starting out, choose a very small region so that you can figure things out quickly with small data sets.

There are several ways of finding latitude and longitude values. Since we are interested in a bounding box, perhaps the clearest way is to use the bounding box selection features of the ‘export data’ link. On the homepage map pan and zoom to roughly the right area, and then click the ‘export data’ (link on the left). This sidebar display includes the four values you need for a bounding box matching the extents of the viewport. Click ‘Manually select a different area’ and then drag a box to select exactly the region you want.

Construct a URL for the HTTP API

You must now construct an API request URL as specified in the map request docs. In the URL, a bounding box is expressed as four comma-separated numbers, in this order: left, bottom, right, top (min long, min lat, max long, max lat). Latitude and longitude are expressed in decimal degrees. North latitude is positive, south latitude is negative. West longitude is negative, east longitude is positive. The method described in the previous section will give you suitable values.


The API is limited to bounding boxes of about 0.5 degree by 0.5 degree and you should avoid using it if possible. For larger areas you might try to use XAPI, for example:*[bbox=11.5,48.1,11.6,48.2]

Refer to the XAPI page for details of other servers available.

Download the data

You can just type this URL into a browser if you want, but that may not work as well as you’d hope, especially if the data is large. If you know how to use them, command-line tools like wget and curl will do a better job.

If you’ve specified a region with a lot of data, you may have to wait a while before the HTTP response begins (the server is crunching your request). If your client times out, try setting options for a longer timeout, or choose a smaller region.

Here’s an example command line for wget:

wget -O muenchen.osm ",48.14,11.543,48.145"

Everything changed with the pandemic. As Spain went into lockdown, its population cloistered at home, Llanos saw his viewership figures explode: His Twitch channel currently commands 7.8 million followers, making him one of the 10 most followed creators on the platform. His YouTube account attracts a similar audience.

The players’ motivation is perhaps a little more calculating than that. “Twitch is the Generation Z platform,” said Julian Aquilina, a broadcasting specialist at the media research firm Enders Analysis. “It skews very young, and quite male. It is quite a different audience to traditional broadcasters.” Llanos offers a precious route into that audience: His interview with Dybala, for example, attracted more than 100,000 live, largely teenage viewers.

It is an approach, Aquilina said, that may become more common. “Twitch is becoming a broadcaster,” he said. “Amazon has done that with some N.F.L. games, putting them on Twitch as well as Prime. If you have the rights to something, you want it distributed across platforms: You can sell the broadcast rights but still have an online presence.”

A la pregunta sobre cuál es la relación entre ciudadanía y ciudad, nos plantea que la ciudadanía es “un cuento chino”, que es ideología pura, y que hoy al hablar de ciudadanía se excluye a un porcentaje de habitantes en la ciudad y que, además, se basa en la falsa premisa de que las personas son libres e iguales.

Para Manuel Delgado no es posible imaginar una ciudad sin conflictos, porque la vida es conflicto y que hoy, para lo urbano como forma de vida, el principal enemigo es la mayoría del urbanismo y la arquitectura, que han servido para convertir la ciudad en el lugar de la usurpación y el apoderamiento para fines económicos y politicos.

The World’s 1st Destroyed Diamond NFT.

So I went and bought a real diamond for $5k—> destroyed it—> minted a NFT for the diamond. I wanted to see how much value the NFT retains.

Digital assets replacing physical ones is an inevitable trend of this century. You cannot afford to not understand it.

Hablar de vivienda colectiva es hablar de vida en común, y por consiguiente, del conflicto como herramienta que nos construye socialmente. Asumir dicho conflicto como parte natural del espacio intermedio que surge entre dos o más partes.

Gran parte de la arquitectura residencial de los últimos años ha optado por negar ese espacio de conflicto. Sin embargo, y como hemos visto, pueden existir formas de asumirlo y trabajarlo. La vivienda del futuro será así la que se materialice como discusión permanente. Recomponer ese binomio (vida-trabajo) establecido por la ciudad industrial y renunciar al imaginario de vivienda dormitorio en favor de una nueva idea de espacio compartido en el que vivir, trabajar, disfrutar y cuidar acompañados.

es curioso que el trabajo de las editoriales, por ejemplo, e imagino que también de productoras de cine y de música, se basa en el hecho de que existan miles de personas dispuestas a trabajar a cambio de nada durante un tiempo –en manuscritos de novelas y guiones, por ejemplo– para después ofrecer algo que tal vez la empresa no quiera. Esto no sería imaginable en otros ámbitos, nadie se pondría a hacer quinientos pares de zapatos si no fuera porque ya le están pagando el tiempo necesario para hacerlos. Pero como en la cultura se trabaja con el ego, con lo especial, con lo «artístico», parece que en sí mismo debería ser recompensa suficiente. En cambio, hay muchas personas con historias que contar que sencillamente no tienen tiempo material para dedicarlo a pasarse dos años haciendo algo que quizá nadie quiera o que, incluso si alguien lo quisiera, lo que le paguen no cubra en absoluto los gastos ni el tiempo dedicado.

Así se establece un sesgo en la cultura: hay que tener tiempo, o un colchón patrimonial familiar, o una situación de no explotación doméstica, o un salario elevado para poder escribir. Si hubiera un interés estatal en que se escuchen distintas voces, se instaurarían procedimientos para que así fuera, pero apenas se hace. En todo caso, sí creo que el capital simbólico es más capital que simbólico, y que la realidad virtual es más realidad que virtual.

…concebir la importancia de los servicios públicos es sencillo, lo difícil es vencer la fuerza que se opone a la pérdida de la máxima rentabilidad.

gran parte de la novela podría datarse en el sentido de contar de dónde viene, con qué sombras estaba boxeando, de quiénes vienen pequeños relatos, reflexiones, alusiones, la información, los caminos para llegar a una idea, en qué conversación, artículo, tuit o mail o lectura o charla surgió una línea de diálogo; tal vez un día si logro tener tiempo haga esa suerte de base de datos, porque sería un modo de demostrar que la idea del inmunólogo Agustín Lage de que las colectividades hacen ciencia a través de los individuos también se da en la literatura y que no es solo algo abstracto ni tampoco significa que no exista el trabajo de una autora o autor, sino que ese trabajo se suma a otros muchísimos.

There two main paths to look for entries to autostart:

/etc/xdg/autostart – called system-wide and most of the application will place files when they are installed.
[user’s home]/.config/autostart – user’s applications to start when the user logs in .

There is a security problem here, which is sometimes installing a package will place an autostart file there because the maintainer decided it is important but the package might be just a dependency and the next time the user logs in unwanted program might execute and open ports!
