Hot Technology Pilots in 2016 – Fear & Chaos in Technology Adoption

Posted on by

Last March I talked about technology pilots and discussed a survey we launched regarding technology adoption. I asked if we were going to invest in IOT, VR/AR, biometrics, analytics and wearables and other technologies or if there was just a lot of hype about “emerging” and “disruptive” technologies. The data we collected was across multiple industries and countries, but primarily from the US. There were nearly as many business professionals as technology professionals who responded to the survey. The Cutter Consortium facilitated the data collection process. (Thanks to everyone that helped us discover a lot of counter-intuitive insights!  A special thanks to Tom Cox and Kaung Khin for their help with the research:  they are my de facto co-authors here.)

New York VC Thrive Captial Raises $700 Million For Fifth Fund

Posted on by

Thrive Capital, a New York-based venture fund which has backed companies like Warby Parker, Instagram, Twitch and has launched a few of its own (Oscar, Cadre, Maple), has closed $700 million for its fifth fund. The raise nearly doubles the $400 million Thrive collected for its last fund in 2014. Reps for Thrive say the fund’s investment team (Joshua Kushner, Miles Grimshaw, Chris Paik, Jared Weinstein, and Kareem Zaki) will focus the new capital on early stage companies. Thrive will also make occasional bets on later-stage growth investments—previous growth plays have included Stripe, Github, and Slack.

Cómo añadir un usuario nuevo a nuestro Gnu/Linux

Posted on by

Al igual que muchos sistemas privativos, Gnu/Linux permite el uso del sistema operativo por parte de diferentes usuarios con distintos roles, algo que es útil no sólo para el mundo de los servidores sino también para otros ámbitos como el educativo o el hogar.

Normalmente todos los escritorios permiten la creación de un usuario nuevo de manera gráfica, un modo que difiere del escritorio, pero la creación vía terminal es algo que es igual en todas las distribuciones Gnu/Linux e independientemente de cualquier escritorio.

Para poder realizar esta tarea a través de nuestro terminal, hemos de abrir una terminal ( como es lógico) y escribir lo siguiente:

useradd USUARIO_NUEVO
passwd USUARIO_NUEVO

Y tras esto te pedirá la contraseña nueva que se relacionará con el usuario creado. También existe la opción de añadir o mejor dicho relacionar el usuario creado con un grupo. Bien podemos añadir el usuario nuevo a un grupo nuevo o bien a un grupo que ha creado la distribución. Para listar los grupos que existen en el sistema operativo hemos de utilizar el siguiente comando:

cat /etc/group

Nos mostrará en pantalla todos los grupos que existe en nuestro equipo. Una vez seleccionado el grupo, para añadir el nuevo usuario a este grupo hemos de escribir lo siguiente:

useradd -n -g migrupo USUARIO_NUEVO

Si por el contrario ya hemos creado ese usuario y queremos mover o relacionar al usuario con el grupo especifico, hemos de escribir lo siguiente:

adduser USUARIO GRUPO

El funcionamiento es sencillo y es similar el que se utiliza en caso contrario. Es decir, si queremos eliminar algún usuario hemos de utilizar los siguientes comandos que funcionarán igual que los anteriores:

  • userdel : Eliminar usuario.
  • groupdel : eliminar grupos.
  • deluser: quitar a un usuario del grupo.

Como podéis ver, el funcionamiento es sencillo y las utilidades que nos puede dar son muchas y no tendremos que depender de conocer o no el escritorio de la distribución Gnu/linux en cuestión.

El artículo Cómo añadir un usuario nuevo a nuestro Gnu/Linux ha sido originalmente publicado en Linux Adictos.

Minecraft Weekly Build Challenge #7: Chunk Towers

Introduction

Greetings, Minecrafters. The support from Chunk House week was massive, so this week we will be making towers from different times, may it be from medieval, modern or futuristic ones. Towers are buildings that are significantly higher than they are wider. It is up for your creativity on how you can fit it in a small space.

Challenge

Easy Mode: Make a tower that fits in a 16 x 16 block space or one chunk.

Hard Mode: Make a tower that fits in a 13 x 13 block space.

PC Users Only: You are required to post one (1) screenshot with chunk boundaries activated using CTRL + G if you are using 1.10 or above.

Everyone else: You are required to post one (1) screenshot with blocks outside the specified space using alternating blocks that show the scale of your build from above.

Rules

  1. Submitting an entry. Photo albums require a specific title [WBC #X] "Title" by Username and Youtube videos require any evidence that it is yours. You may submit in either option. Please also dictate if the submission is in what mode.

  2. Purely vanilla. Use only the classic texture pack. Any mod that add anything new to the game and visual enhancements are not allowed. You may use any mode including creative and any generated terrain. Any minecraft version is allowed include test builds. You may use anything that is part of the normal game including commands.

  3. No pre-existing builds. Things that have been built before the theme announcement will be disqualified. You may have multiple people to help you build instead, but only the commenter will receive the points.

  4. Reporting a player. Private message me and attach any evidence. If proven guilty, the reported player will be disqualified until he or she can prove him / herself.

  5. External programs. Only external programs that will help or guide you build the entry is allowed. They must not add anything new to the game.
