Controlling Zigbee devices with MQTT

Sun, 06 Jan 2019 10:00:00 +0000

This is a short tutorial on connecting a zigbee device (an Aqara cube) to an MQTT server, so you can control your zigbee devices from the network. If you’re anything like me, you’re probably a sucker for IoT devices. For a long time, I’ve been using WiFi-enabled lights, and Amazon dash buttons to control them.

Sharing dotfiles

Today’s post is half a quick note, half public shaming. In other words, it is a reminder to be very careful with OAuth tokens and passwords. As part of moving to emacs, I starting using the incredibly useful gh.el. When you first use it, the extension saves either your password or an OAuth token in your .

Zotero

Zotero is an Open Source tool that lets you organise your bibliography, syncing it with the cloud. Unlike other alternatives such as Mendeley, Zotero can upload the attachments and data to a private cloud via WebDav. If you use nginx as your web server, know that even though it provides partial support for webdav, Zotero needs more than that.

Proxies with Apache and python

Thu, 09 Oct 2014 10:00:00 +0000

This is a quick note on proxying a local python application (e.g. flask) to a subdirectory in Apache. This assumes that the file wsgi.py contains a WSGI application with the name application. Hence, wsgi:application.

Gunicorn

<Location /myapp/>
    ProxyPass http://127.0.0.1:8888/myapp/
    ProxyPassReverse http://127.0.0.1:8888/myapp/
    RequestHeader set SCRIPT_NAME "/myapp/"
</Location>

Developing a python module and publishing it on Github is cool, but most of the times you want others to download and use it easily. That is the role of PyPi, the python package repository. In this post I show you how to publish your package in less than 10 minutes.

Updating EuroLoveMap

Thu, 27 Mar 2014 14:00:00 +0000

As part of the OpeNER hackathon we decided to build a prototype that would allow us to compare how different countries feel about several topics. We used the OpeNER pipeline to get the sentiment from a set of newspaper articles we gathered from media in several languages. Then we aggregated those articles by category and country (using the source of the article or the language it was written in), obtaining the “overall feeling” of each country about each topic.

A simple trick. If you want to remove all the ‘.swp’ files from a git repository, just use: 1 git rm --cached '**.swp'

Creating my web

Thu, 22 Aug 2013 14:14:22 +0000

I’ve finally decided to set up a decent personal page. I have settled for github-pages because I like the idea of keeping my site in a repository and having someone else host and deploy it for me. The site will be really simple, mostly static files. Thanks to Github, Jekyll will automatically generate static pages for my posts every time I commit anything new to this repository.
