Alojando servicios locales en Bolivia

🇧🇴 · R00thouse · Looper

Una de las propuestas que el Hacklab hizo desde hace tiempo va por el lado de la independencia tecnológica. O sea, el poder manejar nuestros propios servicios y no depender de la benevolencia de servicios como Facebook, Twitter (ahora X), Notion, Google Apps, etc. No conviene ser siempre inquilinos Aunque en su momento la idea parece extraña, ya que está muy normalizado usar servicios así en Internet, podemos hacer una comparativa con la propiedad de la vivienda. Cuando usas un servicio ajeno, estás alquilando una pieza pequeña en un hotel gigante: estás pagando (con dinero, o con tus datos) pero tu casita no te pertenece. Todo es para el propietario del hotel, y éste tiene intereses y preocupaciones distintas a las tuyas. Todos se llevan bien porque es bueno para el negocio, pero ¿qué pasa cuando estás en desacuerdo? Puede ser por copyright, censura o temas corporativos ajenos a ti. Si te ves perjudicado, borran tus cosas o limitan tu difusión no puedes hacer nada ya que el lugar nunca fue tuyo. Ahí vienen los Servicios Locales : servicios funcionando en un lugar que controlas. Esto viene a ser ya una casa propia: tú decides quién entra y sale, cómo se usan tus datos, o por cuánto tiempo estarán ahí. Servicios Locales in the wild Hay varios niveles de cosas que podemos considerar Servicios Locales, o self hosted services . Algunas son: La nube No todos los grupos de estudio, comunidades o hacklabs cuentan con un lugar fijo en donde dejar cosas instaladas. De ahí viene el concepto de self hosting en la nube. Consta de alquilar recursos de hardware con un proveedor e instalar el software ahí. Hay proveedores para todo gusto y presupuesto: Hetzner (europeo, low cost) DigitalOcean Amazon AWS (muchas regiones en el mundo, servicios añadidos) OVH (europeo, low cost) Organizaciones como Framasoft, Deuxfleurs y etc. (enfocadas en servicios libres) los han llegado a usar ya que, con economías de escala y una inversión inicial menor pueden tener acceso a mucho hardware y ancho de banda para satisfacer a los usuarios. Como punto en contra, uno aún sigue sujeto a las condiciones del propietario del hardware y la red. Aunque usualmente estas son mucho mejores que un servicio no libre, siguen siendo importantes de revisar. Controlemos el camino Ahora tenemos acceso al servidor, pero no controlamos el camino. Siempre pensamos en Internet como redes de fibra óptica bien cuidadas, pero se parece más al lejano oeste: desde proveedores ambiciosos filtrando o congestionando tráfico intencionalmente, hasta supuestas cajas negras propiedad de organizaciones gubernamentales misteriosas, o la venta de datos Netflow a data brokers. Además, no olvidemos que el acceso a Internet está lejos de ser estable, uniforme e igualitario para todos. Si uno apuesta por la privacidad y un acceso justo, quizás puede pensar en mantener sus servicios locales cerca. Esto se logra comprando servidores, ya sea profesionales antiguos, PCs convencionales o placas ARM como las Raspberry Pi. Además, si quieres distribuir la conexión, puedes armarte tu propio camino también: usando tu propia fibra o enlaces inalámbricos baratos. Guifi.net, sudomesh son un ejemplo de esto.

When was the last time you ran in circles?

🇳🇵 · Karkhana · Karkhana

As we grow up and gain this perspective of what is right and what is wrong, we forget what truly makes us happy. We happen to redefine our definition of fun and decide on a different “ comfort level ” . As we greeted students while on a recent class, we saw the face of confusion in junior students and the boredom on the face of the senior students. They were obliged to gather in the ground under the harsh midday sun. Nevertheless, we began the class, “We will start today’s camp by playing a short game. How many of you have played the game – ‘ fire in the mountain ’?” we asked, none of the students raised their hands so, we told them about the game. “We will be running in circles , yelling ‘Fire in the mountain. Run, run, run!’ As we are running, we will call out a number and you guys will have to make a team of the same number. And if you can’t do that, then your team will be disqualified!” We were all laughing as we played. By the time that we started our third round, the senior students were running round enthusiastically in circles. We called out the last number: 3, and we had all the teams ready. The first half of the class was about motion and its transformation. When building a prototype of an “ automaton ”, the students discovered that we could convert circular motion to linear motion with a simple mechanism. They realized that this could be related to real-life situations. By the time we announced that we were having a ten-minute break, we were tired from running from one corner of the classroom to another. Our class was run in a medium sized hall that had a total of sixteen tables, each with three chairs. “We only have five minutes left for the break. Aren’t you guys going out?”,we said. “No, we want to complete our activity first!” replied the team. All the team members were busy cutting papers and trying to make their project functional. We personally don’t remember having a dedication like that in any of my classes when we used to be a school student. We went to the class on the second day – all the necessary materials; prepared the night before. Then, started the class with an energizer called ‘jump-in-jump-out’. Then, we divided the students into two groups. And then we immediately handed out the instruction sheets to the students. “How many of you know what soldering is? Or have ever soldered something before?”, we asked. Four students raised their hands, so we instructed them to share with their friends what soldering was. Even if we had motors and battery caps ready for use, we instructed the teams, one at a time, and encouraged them to solder their own motors and battery caps. As some teams got busy in that, other teams worked on their prototypes of vibrator motor bots. We were a little disheartened seeing just 8 girls in a pool of 48 students. And even their hands trembled as they carried the soldering irons. We also had to guide them how to hold a wire stripper properly. We felt accomplished by the end of the class as we saw students working at the soldering station – with their hands not trembling. At the end of the class, we had a quick battle of bots to pick the ultimate bot of the day. And the students gathered around the battlefield and cheered for their favorite bots! By the time the class ended, and we got ready for a group picture, we were thirty-two minutes later than the calculated time. And even if the students were supposed to be having their lunch at this time, none of them complained about being hungry or about wanting to leave the hall. Yes, learning is definitely an experience, and we can’t feel more happy and grateful that we get to provide that to our students. On the way back to their own classroom, one of the students came up to us and said, “ Please, definitely come to our school for the next year! ” The post When was the last time you ran in circles? appeared first on Demo Main .
