Elon Musk is known to be particularly apprehensive about artificial intelligence. Although many of us are both excited and worried about the potential future of AI, most don't need to fear computers taking over in the creative realms of society.

Designing Foils with XFLR5

Linux Journal - mer, 04/08/2015 - 11:54

For any object moving through a fluid, forces are applied to the object as the fluid moves around it. A fluid can be something like water, or even something like the air around us. When the object is specifically designed to maximize the forces that the fluid can apply, you can designate these designs as airfoils. A more common name that most people would use is a wing. more>>

Whatever your opinions about Do Not Track, set them aside for a minute and just look at what the words say and who says them. Individuals—the people we call "users" (you know, like with drugs)—are the ones saying it. In grammatical terms, "do not track" is spoken in the first person. more>>

Not So Dynamic Updates

Linux Journal - lun, 03/30/2015 - 11:33

Typically when a network is under my control, I like my servers to have static IPs. Whether the IPs are truly static (hard-coded into network configuration files on the host) or whether I configure a DHCP server to make static assignments, it's far more convenient when you know a server always will have the same IP. more>>

Montréal-Python 53: Sanctified Terabit + MTLData + DevOpsMTL + DockerMTL

Montreal Python - jeu, 03/26/2015 - 23:00

Sketch credit Cynthia Savard

If PyCon is not enough, Montréal-Python has the solution: a meetup! Now that your first incredible day of sprints is over, we are bringing on stage some of PyCon's superstar presenters for encore presentations.

This special Montréal-Python edition will be co-organized by MTLData, DevOpsMTL and DockerMTL.

Trey Causey: Scalable Machine Learning in Python using GraphLab Create

I'll be giving an overview of how to use GraphLab Create to quickly build scalable predictive models and deploy them to production using just an IPython notebook on a laptop.

Nina Zakharenko: Technical Debt - The code monster in everyone's closet

Technical debt is the code monster hiding in everyone's closet. If you ignore it, it will terrorize you at night. To banish it and re-gain your productivity, you'll need to face it head on.

Olivier Grisel: What's new in scikit-learn 0.16 and what's cooking in the master branch.

Scikit-learn is a Machine Learning library from the Python data ecosystem. Olivier will give an overview and some demos of the (soon to be | recently) released 0.16.0 version.

Jérome Petazzoni: Deep dive into Docker storage drivers

We will present how aufs and btrfs drivers compare from a high-level perspective, explaining their pros and cons. This will help the audience to make more informed decisions when picking the most appropriate driver for their workloads.

Pierre-Yves David: Mercurial, with real python bites

In this talk, we'll go over on the advantages of Python that helped the project both in its early life when so much feature needs to be implemented, but also nowaday when major companies like Facebook bet on Mercurial for scaling. We'll also point at the drawback of choosing Python and how some work-arounds had to be found. Finally, we'll look at how the choice of Python have an impact on the user too with a demonstration of the extensions system.

Thanks also to our special sponsors for this event: Docker Inc. and LightSpeed Retail

Nicolas Kruchten: Lightning talk

Nicolas Kruchten will be giving the first ever public demo of Datacratic's Machine Learning Database (MLDB): a product which is distributed as a Docker image and which uses Python as a plugin and scripting language.
