Turning Ipad Into a Remote Development Tool

Tue, 20 Feb 2024 21:14:08 +0000

I’ve talked before about how much I love the form factor, versatility, portability, and battery life of the iPad. It’s by far the gadget I enjoy the most. Even for development, even when working remotely, it’s ideal as long as you don’t rely too much on developer tools.

As I sit down to write this post in 2024, I can’t help but acknowledge the fact that my blog has remained silent for far too long. It’s not for lack of things happening, but maybe because the everyday hustle and bustle have swallowed up my creative energy (or whatever is being called nowadays).

This afternoon I managed to carve out some time for myself, so with the new hard drive that arrived earlier, I dived into playing with #NixOS on a PC. Since I already had a minimal virtual machine set up for testing, after booting from a USB and installing the base system, git cloned the configuration, tweaked a couple of hardware and networking settings.

iPad as Dev Machine

Have you ever considered using an iPad for coding? While an iPad may not be the most obvious choice for developers, it can serve as a valuable complement to your main development setup, thanks to its long battery life, portability, and superb keyboard.

Though it's not the most ideal tool with its limitations and dependencies (like VPN, data connections, remote services, etc...) but it's just so convenient that it annoys me. From my pov, the touchscreen, the supreme keyboard, and that 'open-and-go' feeling are incomparable to any other portable machine.

In software engineering, #rubberduck debugging (or #rubberducking) is a method of debugging code by articulating a problem in spoken or written natural language. The name is a reference to a story in the book «The Pragmatic Programmer» in which a programmer would carry around a rubber duck and debug their code by forcing themselves to explain it, line-by-line, to the duck.

Sigamos tirando del hilo de los recently, son la excusa fácil para volver a contar cosas. Le he estado dando vueltas a ver si encajaba mejor una estructura de subtemas más o menos fija o variar según lo acontecido y creo que de momento me decanto por lo segundo.

Un par de pequeñas coincidencias me han empujado a desempolvar esa «fina capa de mugre» que recubre el entorno administrativo de este CMS. Hacía tiempo que no me daba una vuelta por los feeds de la blogosfera (si es que el término sigue siendo válido en 2021) y entre que he descubierto que el amigo Juanjo ha abierto un nuevo blog y que Andrés me ha dado a conocer los "

Despues de varias aventuras y - sobre todo - desventuras con brew, he tomado la decisión de minimizar - o intentarlo al menos - que las dependencias de mis múltiples entornos de desarrollo estén enganchadas o dependan - valga la redundancia - directamente del gestor de paquetes del sistema, por lo que pueda pasar.

When you are a kind of old school, modern times means a bit of pain in some way. Your soul is mostly seeking inner peace but on the other hand, as someone that works with technology, you wouldn't stay freeze.

IRSSI: Hilighting your nick

Tue, 11 Feb 2020 20:59:09 +0000

I'm still - and proudly - using irc for daily contact with my team mates and it's perfectly fine for our purposes. Well, I miss so much a couple of things (like edit a message with typos or the ability to easily share a photo/screenshot) but we're witty enough to manage among us.

World Roller Games 2019

From June 27th to July 15th I was attending to the World Roller Games 2019, the world's largest event comprising all the world championship roller sports disciplines. As group of developers, our commitment there was keep the homogeneity of the data transfered by the different companies who are the responsibles for the different disciplines.

New backpack

Thu, 13 Jun 2019 20:53:55 +0000

Who doesn't like the backpacks?, I have to admit that I have a kind of fetich with the backpacks in general and with the everydaycarry (edc) in particular. I really like to poke the nose into other's backpacks and take ideas here and there to improve the stuff I carry daily.

Docker all the things

Algo tan sencillo y aparentemente inocuo como un punto de montaje puede convertirse en una letal arma de destrucción de paciencia/tiempo.

In a try to go back to my roots, lately, I'm using the terminal as much as I can and it's being a real pleasure. Even to listen music. My consumption habits - talking about music - mostly go through youtube and local music, it depends on the situation.

Darcs: Fixing a wrong amend

Fri, 30 Oct 2015 10:58:24 +0000

I must admit I often get confused when recording a new patch based on a previous one. Sometimes I amend instead of creating a new record, and once it's done it's not easy to rollback.

Upgrading Django to 1.8

Sat, 06 Jun 2015 00:24:40 +0000

As they said, having last version has several benefits: New features and improvements are added. Bugs are fixed. Older version of Django will eventually no longer receive security updates. Upgrading as each new Django release is available makes future upgrades less painful by keeping your code base up to date.

irssi: playing with multiline paste

Thu, 21 May 2015 11:47:18 +0000

It's not quite known that some of us are still using irc as main channel for projects. I have to admit that without irc wouldn't have been able to talk with many interesting people, even lead developers in great opensource projects.

Casual fun with tests

Using mercurial a la darcs

Thu, 09 Apr 2015 10:54:41 +0000

Nowadays using a version control system is as basic as using an editor. I have to admit I'm a mercurial fanboy because it's clear, simple and written in python. In some other projects we're using darcs, similar to mercurial but with a different approach.

Python, Zombie, forms, tables and tests

Tue, 07 Apr 2015 22:25:11 +0000

Sometimes you feel that the world is against you, sometimes it's a computer what makes your life miserable. This time was a cocktail of elements. Trying to test a simple form functionally from python-zombie was like a nightmare.

Feeling an old techie

Wed, 25 Mar 2015 19:00:19 +0000

I was thinking about that feeling lately. It seems that I can not follow the wave out there, there are many things escaping from my comprehension due lack of time. Starting to talk about anything not related to my day-by-day is starting to feeling myself out of date.

ZODB, how to properly delete a BLOB file

Tue, 25 Nov 2014 22:48:23 +0000

Bash shellshock bug update: loving Fabric

Django deploy: problems with limited hosting

Mon, 21 Jul 2014 21:51:18 +0000

Some months ago I had to deal with a Symfony2 project in a shared hosting (Spanish article) and now the big next deal is a similar task with Django. The project is almost done and I have the hosting credentials, once I'm in I noticed that there is no chance to configure anything (Apache, WSGI or whatever) so I was a bit lost.

GPG: Revalidate expired key and add new email account

Sat, 05 Jul 2014 11:57:04 +0000

When you are creating a new GPG key you have to decide how long the key will be valid before to renew. In my case when I got my own key, I was not really thinking on use it daily, it was years ago, just for test and have fun.

Logwatch, add a new postfix custom service

Sun, 08 Jun 2014 12:47:33 +0000

Last days ago I had lot of problems with MTA servers, hacked accounts, bad redirects policies and some other minor issues that kept me with the hands dirty in sysadmin keyboard. Needless to say how I love to put my sysadm hat and start to fix and/or optimize stuff, so from that bunch of problems was born this little script that makes my days easier than before.

Tmux: detach otras sesiones que no son la tuya

Thu, 15 May 2014 04:11:47 +0000

Una de las fantáticas features de tmux es la sencillez con la que puedes conectar múltiples clientes a la misma sesión de forma simultánea. Si lo has hecho alguna vez, con terminales de diferentes tamaños, habrás visto algo tal que así:

Django and memcache: clear cache keys

Wed, 05 Feb 2014 13:35:54 +0000

Let's play Django with Memcached. As the great framework Django is, it's so easy to activate any kind of cache in your project. Memcached is one of the options, but you can also work with DatabaseCache, FileBasedCache, LocMemCache, MemcachedCache, DummyCache (a kind of non-cache very useful for devel/test enviroments) or - of course - your own CustomCache if you want.

Mercurial: pager extension

Thu, 23 Jan 2014 15:19:07 +0000

Sometimes when you are using Mercurial you want to paginate the output results. With paginate I mean use someting like bash more or less commands. Trying to focus yourself in a long list display is nearly imposible without a pager, so you can do it old-school-style:

Restaurar InnoDB partiendo solamente de archivos

Thu, 05 Dec 2013 14:42:23 +0000

El título suena muy a "la he liado parda por favor échame una mano". En efecto. Básicamente (y creo que lo repetiré varias veces a lo largo del artículo para que queda claro), la mejor solución para no llegar nunca a este punto es hacer dumps de vuestras bases de datos.

Pyramid: 6 - Forms (simpleform)

Mon, 04 Nov 2013 19:00:00 +0000

Aunque hasta ahora es cierto que hemos creado un model (bueno, dos), una view y una template, hemos configurado el root context de la aplicación y sabemos más o menos cómo funciona y cómo movernos por ella, de momento no hemos interactuado demasiado con el ZODB, nos falta agregar datos a ese modelo Twitts que creamos en su día y, obviamente, mostrarlos.

Pyramid: 5 - Views y Chameleon Templates

Sun, 03 Nov 2013 19:00:00 +0000

Siguiendo con esta serie de artículos sobre Pyramid y ZODB ya hemos escrito nuestros primeros modelos, así que ya podemos interactuar con ellos de alguna forma: a través de las views.

Pyramid: 4 - Models

Sat, 02 Nov 2013 19:00:00 +0000

Si hacemos memoria, hasta el momento ya sabemos montar un proyecto y un entorno mínimo de trabajo, entendemos la estructura del mismo, incluso nos hemos arriesgado a modificarla ligeramente según nuestras necesidades; y sabemos a pies juntillas cómo funciona el despachador de urls de Traversal contra la ZODB.

Pyramid: 3 - URL Dispatching y ZODB Traversal

Fri, 01 Nov 2013 19:00:00 +0000

En capítulos anteriores hemos visto cómo montar el entorno y cómo entenderlo y adaptarlo mínimamente a nuestras necesidades organizativas. Hoy trataremos de abordar el tema del despachador de URL's... ¡qué mal suena en castellano!

Pyramid: 2 - Entendiendo la estructura del proyecto

Thu, 31 Oct 2013 19:00:00 +0000

En la anterior entrada hemos visto lo más básico de cómo crear un entorno y un proyecto inicial con Pyramid + ZODB, en este post vamos a intentar entender el proyecto y adaptarlo un poco a nuestra forma de trabajar, para ello nada mejor que empezar echándole un vistazo a lo que pcreate ha hecho por nosotros:

Pyramid: 1 - Montando entorno y proyecto con ZODB

Wed, 30 Oct 2013 19:00:00 +0000

Las series de artículos no son lo mío, creo que no he llegado a completar las que he empezado, pero hay que intentarlo. Entiendo que con esa premisa serán pocos los arriesgados lectores que lleguen al final, pero es una de las excusas que tengo para ponerme al lío con este nuevo reto, así que el que avisa.

Django: limpiando usuarios desde shell

Thu, 12 Sep 2013 23:03:29 +0000

Mercurial: Merge branches

Wed, 17 Jul 2013 10:38:15 +0000

Tarde o temprano llegaría la hora de trabajar con branches. Y ello lleva inequívocamente a tener que mezclarlas algún día. Suponiendo un escenario de repositorio con dos ramas (default, new), una vez el código es estable y está probado, haremos lo siguiente:

Disconnecting a bit

Thu, 13 Jun 2013 06:52:10 +0000

Cambiar kernel en ovh con grub (nfs)

Mon, 11 Mar 2013 07:59:44 +0000

El principal problema que existe para montar un servidor NFS en OVH es que los kernels que habilitan por defecto (OVH + grsec), además de venir con grsec como su propia descripción indica, no tienen soporte para instalar módulos de kernel.

Pair programming con tmux

Mon, 25 Feb 2013 08:56:09 +0000

Con screen era sencillo crear un entorno para el pair programming, pero con tmux también es trivial. Me refiero a compartir una sesión de terminal para poder interactuar desde varias localizaciones distintas:

Darcs: otra forma de trabajar

Fri, 11 Jan 2013 17:18:13 +0000

Si tengo que ser sincero, desde un principio he sido bastante reacio a la moda esta de los sistemas de control de versiones. Estaba tan agusto y acomodado con mis copias de seguridad y mis carpetas fechadas que me daba una pereza enorme ponerme a aprender un nuevo sistema que, sin duda, me obligaría a cambiar la forma de trabajar.

Se me hace muy cómodo tener un atajo de teclado para la típica orden de "ir a la linea X", así que en vez de escribir todo el tochaco de comando que hace falta en Emacs para ello (M-x goto-line<RET>#linea<RET>) voy a hacer un binding.

Flask-HTMLBlog

Thu, 07 Jun 2012 00:32:24 +0000

Así de extraño suena el nombre del último proyecto que lleva dando vueltas entre las perdidas neuronas de mi extremidad superior. ¿De qué se trata?, de un cúmulo de cosas...

Os habréis dado cuenta que hace un tiempo me entretiene bastante todo lo relacionado con Flask y Django, pero como buen newbie que soy, no me sentía cómodo sin un proyecto en el poder practicar el learn by doing.

Django: Cambiando de DB Engine

Sat, 28 Apr 2012 18:42:31 +0000
Normalmente las especificaciones de un entorno de desarrollo y las de un entorno en producción suelen ser bastante diferentes. Quizás en el primero buscas la comodidad mientras que cuando se hace el deploy a producción priman otras cosas.

Desarrollo web con Python: Flask

Wed, 15 Feb 2012 18:47:34 +0000

Hace algún tiempo empecé a utilizar Flask para un proyecto personal. Flask es un mini framework de desarrollo en python que me ha convencido desde el principio por su sencillez. Intentaré exponer un pequeño ejemplo para que os hagáis una idea de cómo funciona.

Y como Álex ha escrito un completo tutorial sobre Pylons/Pyramid con un ejemplo de aplicación, no quería ser menos y explicar mis aventuras y desventuras con esta otra pequeña joya de Python así que allá vamos.

Nginx

Thu, 10 Nov 2011 21:16:03 +0000
Cuando algo tan sencillo de instalar y de configurar se convierte en un servicio mejor que sus antecesores en prácticamente todas sus características podemos decir que hemos dado un salto de calidad importante.

Apache + Squid + Nginx

Fri, 28 Oct 2011 23:50:34 +0000

¡Menuda combinación!. A decir verdad empecé jugando un poco con el maldito slowloris y al final acabé montando este batiburrillo de servidores, primero para paliar el efecto del dichoso gusano y segundo para preparar el servidor para la inminente nueva versión del blog - que me gustaría estrenar con el décimo aniversario de este humilde rinconcito -.

En un esquema inicial analógico de esos que tantos nos gustan podemos ver la pirula (pido perdón de antemano por la calidad de la foto):

Apache: Alta carga de CPU

Tue, 09 Aug 2011 10:27:52 +0000

Llevo desde el fin de semana con la mosca detrás de la oreja. Uno de los servidores que administro ha visto incrementada de forma inexperada su carga media de CPU sin motivo aparente. Donde el load average normal de 1 minuto variaba entre 0.40 y 0.80 de repente suponía cargas tan elevadas como 60 o 100 unidades.

En esos momentos puntuales que llegaban a dejar la máquina zombie el proceso que abarcaba un consumo de entre el 60% y el 90% de CPU era apache2. Intrigante que ni error.log ni slow-queries.log de MySQL (lo que normalmente suele ser cuello de botella) dieran ninguna pista.

Hacer scroll en GNU Screen

Mon, 11 Apr 2011 12:31:43 +0000
Me ha pasado un par de veces y siempre he acabado en el mismo sitio así que he decidido documentarlo con un mini-post, porque seguro que no será la última vez que me pase.

Django + virtualenv + pip

Wed, 23 Feb 2011 21:37:56 +0000

No lo tenía claro, pero cuando entendí lo que suponía y cómo se trabajaba con virtualenv + pip me decidí a probarlo. Voy a intentar explicar como se utilizan estas herramientas de una forma genérica, para hacernos una idea de lo que significa y los casos en los que se pueden aplicar. A grandes rasgos:

Django: Framework en python, creo que no necesita mucha más explicación.

Virtualenv: Herramienta necesaria para crear un entorno virtual de python, con las versiones específicas de los paquetes y/o dependencias que hagan falta para el proyecto.

Pip: Gestor/Instalador de esos paquetes (similar a easy_install).

Con estas herramientas intentaremos instalar un entorno virtual independiente para gestionar todas las dependencias de nuestro proyecto.

¿Codeigniter-Reactor + esteroides?

Fri, 04 Feb 2011 20:09:38 +0000

Es algo que todavía no llego a entender ni asimilar. He pasado la mayor parte de la tarde para configurar la nueva versión 2.0 de CodeIgniter-Reactor con varias librerías que, para mi forma de desarrollar, son indispensables en cualquier framework de programación orientado a web:

HMVC: Gracias a la librería de Wiredesignz podemos ordenar nuestro código en módulos y simplificar la lógica de la aplicación.

ModulesModule: Ahora que todo será un módulo, no vendría mal un módulo encargado de ejecutar las tareas más comunes de los módulos (instalar, desinstalar, actualizar...). Un módulo de módulos.

SettingsModule: No me gusta cargar la configuración desde ficheros config/*, por comodidad y para que el usuario pueda cambiar cualquier parámetro ajustable de una aplicación, prefiero hacerlo en base de datos y cachearlo a disco si es necesario. Me quedo con la librería de PyroCMS.

ThemesModule: Otra característica imprescindible sería tener una aplicación themeable y que desde un interfaz de administración se pueda cambiar tranquilamente el aspecto de la misma. Para ello podemos hacer uso de este módulo capaz de instalar y desinstalar themes.

TemplateLibrary y TagsLibrary: Una vez hemos decidido hacer la aplicación modular y themeable siguiendo el patrón MVC, un buen lenguaje de template para que los diseñadores no se vuelvan locos con el lenguaje dinámico sería un punto más.

MigrationsLibrary: Una vez lo pruebas se convierte en musthave. Se trata de una librería para hacer migraciones de versiones en base de datos. Gestiona los cambios entre versiones de forma sencilla.

Dovecot, pequeñas peculiaridades

Tue, 07 Sep 2010 09:20:13 +0000

Desde hace algún tiempo -y después de haber lidiado con Cyrus y Courier- he optado por Dovecot como servidor POP3 e IMAP para máquinas en producción. Por varios motivos: la sencillez de configuración, sigue los estándares, soporta mbox y Maildir y algo muy importante, tiene un backend de autentificación SMTP compatible con Postfix (entre otros).

Sin duda el servicio de correo electrónico es el menos agradecido y probablemente el más doloroso para el sysadmin pero el haber dado con esta combinación de elementos me ha ahorrado un montón de problemas.

De todos modos en la última instalación que me ha tocado he encontrado un par de peculiaridades que me gustaría documentar por si alguien se encuentra en la misma situación.

Limitando usuarios ssh en Mercurial

Wed, 21 Jul 2010 01:24:05 +0000

Si algo bueno tiene Mercurial es que permite la autentificación de usuarios a través de SSH. Es muy sencillo agregar un nuevo usuario a un desarrollo/repositorio: adduser y con meterlo dentro del grupo correspondiente al desarrollo llegaría. Pero ¿qué ocurre si no queremos que ese usuario haga otra cosa que no sean comandos hg?.

Conociendo la existencia de hg-ssh no ocurre demasiado, se trata de un script que hemos de referenciar en el authorized_keys del usuario que acabamos de crear de forma que todos los comandos entrantes pasen por este script. El script se encarga de parsear el comando que se pide en ejecución: si es de la familia de Mercurial lo ejecuta, en cualquier otro caso mostrará un error.

Ejemplo de authorized_keys:

command="~/hg-ssh /home/repo1 /home/repo2",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty ssh-dss AAAA...
He optado por copiar el archivo hg-ssh en el directorio home del usuario, pero se podría referenciar directamente el que trae de ejemplo la instalación de Mercurial.

Papá, ¡somos campeones del mundo!

Me compraste mi primer balón, mi primera equipación, me enseñaste a jugar limpio, a vivir los partidos con entusiasmo, con emoción pero con serenidad, a creer siempre en el buen fútbol, en la humildad, en los buenos jugadores.

Mercurial sobre Apache

Fri, 07 May 2010 14:52:47 +0000

Mi predilección por Mercurial ha quedado patente en algún que otro post, así que una vez estamos conforme con nuestro servidor de versiones llega el momento de dar un paso más. Intentaremos configurar un interfaz web para mostrar el código a todo el mundo (una especie de Trac solo para código y adaptado a Mercurial).

El proceso es tan sencillo como crear otro VirtualHost en tu Apache con unas características un poco especiales porque en vez de tirar de archivos dinámicos (.php, .asp…) vamos a tirar de un cgi en Python, así que la configuración sería algo así:

Mercurial: automatizando al máximo

Thu, 18 Mar 2010 13:28:20 +0000

Cuando trabajamos con servidores de versiones seguro que hay muchas razones de peso de por medio, una de ellas -la que veremos- puede ser la replicación de código en diversas máquinas.

Supongamos un montón de máquinas que comparten el mismo código de repositorio, el orden de propagación de un cambio en todas esas máquinas es sencillo:

Programamos dicho cambio en nuestro servidor de desarrollo (devel).

Hacemos un commit local (en sistemas de versionado distribuido -como Mercurial- cada repositorio también es servidor).

Lo siguiente es un push al servidor donde almacenamos el código (repo código).

Ahora tocaría entrar en cada una de esas máquinas en las que queremos propagar el código y ejecutar un hg pull ; hg update.

Mercurial en Fedora Core 4 y CentOS 5

Mon, 08 Mar 2010 17:22:14 +0000

Necesitaba instalar Mercurial en varias máquinas totalmente desactualizadas, concretamente una Fedora Core release 4 (Stentz) y una CentOS release 5 (final), pensé que iba a ser un lío de dependencias pero al final ha resultado inexplicablemente más sencillo de lo esperado:

Mercurial: Hook on push

Sun, 21 Feb 2010 13:21:26 +0000
Lo tenía pendiente desde que cambié de Subversion a Mercurial, sabía que se podía y que era algo trivial pero lo vas dejando y bueno, just happens. El caso es que cuando haces un push al servidor lo normal es hacer un update de su lado, así que el hook que lo automatiza es el correspondiente:

El mejor firewall

Thu, 11 Feb 2010 16:16:22 +0000
Lo he visto en puntogeek a través del twitter de demogar y me ha parecido tan gracioso que he caido en el burdo copy-paste: Una célula humana contiene 75MB de información génetica.

Rooted CON

Fri, 15 Jan 2010 09:51:00 +0000
Hay un nuevo evento en el panorama de la seguridad informática a nivel nacional. Para despistados -que los habrá :D- estoy hablando de la Rooted CON. Un grupo de profesionales -y fanáticos de la seguridad- se han juntado para ofrecer un congreso con conferencias altamente técnicas desde un enfoque práctico y neutral.
