Download Android Os for Phone Open Source Mobile OS Alternatives to Android
download android os for phone Open Source Mobile OS Alternatives To Android. It’s no exaggeration to say that open source operating systems rule the world of mobile devices. Android is still an open-source project, after all. But, due to the bundle of proprietary software that comes along with Android on consumer devices, many people don’t consider it an open source operating system. So, what are the alternatives to Android? iOS? Maybe, but I am primarily interested in open-source alternatives to Android. I am going to list not one, not two, but several alternatives, Linux-based mobile OSes . Top Open Source alternatives to Android (and iOS) Let’s see what open source mobile operating systems are available. Just to mention, the list is not in any hierarchical or chronological order . 1. Plasma Mobile. A few years back, KDE announced its open source mobile OS, Plasma Mobile. Plasma Mobile is the mobile version of the desktop Plasma user interface, and aims to provide convergence for KDE users. It is being actively developed, and you can even find PinePhone running on Manjaro ARM while using KDE Plasma Mobile UI if you want to get your hands on a smartphone. 2. postmarketOS. PostmarketOS (pmOS for short) is a touch-optimized, pre-configured Alpine Linux with its own packages, which can be installed on smartphones. The idea is to enable a 10-year life cycle for smartphones. You probably already know that, after a few years, Android and iOS stop providing updates for older smartphones. At the same time, you can run Linux on older computers easily. -
Diseño De Un Prototipo Electrónico Para El Control Automático De La Luz Alta De Un Vehículo Mediante Detección Inteligente De Otros Automóviles.”
Tecnológico de Costa Rica Escuela Ingeniería Electrónica Proyecto de Graduación “Diseño de un prototipo electrónico para el control automático de la luz alta de un vehículo mediante detección inteligente de otros automóviles.” Informe de Proyecto de Graduación para optar por el título de Ingeniero en Electrónica con el grado académico de Licenciatura Ronald Miranda Arce San Carlos, 2018 2 Declaración de autenticidad Yo, Ronald Miranda Arce, en calidad de estudiante de la carrera de ingeniería Electrónica, declaro que los contenidos de este informe de proyecto de graduación son absolutamente originales, auténticos y de exclusiva responsabilidad legal y académica del autor. Ronald Fernando Miranda Arce Santa Clara, San Carlos, Costa Rica Cédula: 207320032 3 Resumen Se presenta el diseño y prueba de un prototipo electrónico para el control automático de la luz alta de un vehículo mediante la detección inteligente de otros automóviles, de esta forma mejorar la experiencia de manejo y seguridad al conducir en la noche, disminuyendo el riesgo de accidentes por deslumbramiento en las carreteras. Se expone el uso de machine learning (máquina de aprendizaje automático) para el entrenamiento de una red neuronal, que permita el reconocimiento en profundidad de patrones, en este caso identificar el patrón que describe un vehículo cuando se acerca durante la noche. Se entrenó exitosamente una red neuronal capaz de identificar correctamente hasta un 89% de los casos ocurridos en las pruebas realizadas, generando las señales para controlar de forma automática los cambios de luz. 4 Summary The design and testing of an electronic prototype for the automatic control of the vehicle's high light through the intelligent detection of other automobiles is presented. -

Linux – Das Umfassende Handbuch 1.430 Seiten, Gebunden, Mit CD, 14
Know-howWissen, wie’s für geht. Kreative. Leseprobe In dieser Leseprobe erhalten Sie einen Einstieg in die Linux-Welt und erfahren, wie Sie Audio und Video unter Linux nutzen. Dar- über hinaus lernen Sie die Kommandozentrale kennen: die Shell. Außerdem können Sie einen Blick in das vollständige Inhalts- und Stichwortverzeichnis des Buches werfen. »Was ist Linux?« »Installationsgrundlagen« »Audio und Video« »Die Shell« »Software- und Paketverwaltung« Inhaltsverzeichnis Index Der Autor Leseprobe weiterempfehlen Michael Kofler Linux – Das umfassende Handbuch 1.430 Seiten, gebunden, mit CD, 14. Auflage 2015 49,90 Euro, ISBN 978-3-8362-3775-8 www.rheinwerk-verlag.de/3855 “buch” — 2015/11/5 — 21:54 — page 25 — #19 1 Kapitel 1 Was ist Linux? Um die einleitende Frage zu beantworten, erkläre ich in diesem Kapitel zuerst einige wichtige Begriffe, die im gesamten Buch immer wieder verwendet werden: Betriebs- system, Unix, Distribution, Kernel etc. Ein knapper Überblick über die Merkmale von Linux und die verfügbaren Programme macht deutlich, wie weit die Anwendungs- möglichkeiten von Linux reichen. Es folgt ein kurzer Ausflug in die Geschichte von Linux: Sie erfahren, wie Linux entstanden ist und auf welchen Komponenten es basiert. Von zentraler Bedeutung ist dabei natürlich die General Public License (kurz GPL), die angibt, unter welchen Bedingungen Linux weitergegeben werden darf. Erst die GPL macht Linux zu einem freien System, wobei »frei« mehr heißt als einfach »kostenlos«. 1.1 Einführung Linux ist ein Unix-ähnliches Betriebssystem. Der wichtigste Unterschied gegenüber historischen Unix-Systemen besteht darin, dass Linux zusammen mit dem vollstän- digen Quellcode frei kopiert werden darf. Ein Betriebssystem ist ein Bündel von Programmen, mit denen die grundlegend- Betriebssystem sten Funktionen eines Rechners realisiert werden: die Schnittstelle zwischen Mensch und Maschine (also konkret: die Verwaltung von Tastatur, Bildschirm etc.) und die Verwaltung der Systemressourcen (CPU-Zeit, Speicher etc.). -

Fáciles porque podría doblar la longitud de este proyecto solo agradeciendo a mis padres la infinita paciencia que han tenido conmigo, el apoyo que me han dado siempre, y el esfuerzo que han hecho para que estas líneas se hagan realidad. Por todo ello y mil cosas más, gracias. Mamá, papá, lo he conseguido. Fáciles porque sin mi tutor Antonio, este proyecto tampoco sería una realidad, no solo por su propia labor de tutor, si no porque literalmente sin su ayuda no se hubiera entregado a tiempo y funcionando. Después de esto Antonio, voy a tener que dejarme ganar algún combate en kenpo como agradecimiento. Fáciles porque, sí melones os toca a vosotros, Alex, Alfonso, Manu, Sama, habéis sido mi apoyo más grande en los momentos más difíciles y oscuros, y mis mejores compañeros en los momentos de felicidad. Amigos de Kulturales, los hermanos Baños por empujarme a mejorar, Pablo por ser un ejemplo a seguir, Chou, por ser de los mejores profesores y amigos que he tenido jamás.
