arch linux, gnome-3.20 and xf86-input-synaptics

I am running arch linux with gnome desktop on a Lenovo Thinpad X230. Some time ago gnome 3.20 was released and apparently the synaptics driver is not supported any more.

The only reason I ran into this was because “tap to click” was turned on all of sudden and it interfered with my typing.

Initially, I heeded the advice on the synaptics wiki page: “Synaptics is no longer supported under GNOME. Migrate to libinput.” but the libinput driver was intolerably slow on my system even though I cranked the touchpad speed up to the max.

Anyway, I went back to the synaptics driver and disabled the irritating “tap to click” behaviour by setting the following values in /usr/share/X11/xorg.conf.d/50-synaptics.conf:

Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
Option "TapButton1" "0"
Option "TapButton2" "0"
Option "TapButton3" "0"
EndSection

I hope this helps:)

Exciting times ahead!

If you followed my tweets in the last couple of weeks you may have noticed a new interest of mine: crypto finance.

Decentralised/crypto finance facilitates fast, global and secure transactions without hold-ups at national boundaries and the need to trust third parties, governments or central banks.

This is powerful and bound to bring about change on the same scale as the internet IMHO.

I hence consider myself lucky to join the party as a director of engineering for Monetas, one of the hottest startup companies in the decentralised/crypto finance space.

Based on the open source http://opentransactions.org/ project started by Chris Odom Monetas is building a universal transaction platform that facilitates the trading of all kinds of commodities including bitcoin or any other crypto currencies.

If you’d like to learn more, see this short video on our vision or a more detailed/longer video on the problems Monetas is looking to solve and the benefits of the Open Transactions platform.

P.S.: you have strong C++ development or testing and Q/A chops and wanna change the world with us? Please send your CV to careers at monetas dot net.

Shifting gears

After almost 2 years with the OpenQuake project I will be joining Rackspace as a technical cloud advocate on 01-Nov-2012.

This is novel and exciting in many ways as I will have the opportunity to pursue long standing interests and passions (cloud computing, scalable and robust IT architectures, open source, strategic thinking, reaching out to technical audiences etc.) as part of my *day* job.

I am looking forward to working with the good folks at Rackspace, the cloud community at large and anybody interested in putting cloud technology to good use!

See you around!

EuroPython talk info

The slides from the EuroPython talk (python & amqp) I held this morning are here. I’ll post a link to the video when it becomes available.

There are two things I wanted to mention but did not get to:

  1. python-celery: if you are looking to partition and distribute computations do take a look at it. We are using it in the OpenQuake project and are very happy with it.
  2. RabbitMQ in Action: in case you are using RabbitMQ or plan to do so get this book. I started reading it recently and derived a lot of value from it.
