Linux Journal - Mon, 09/29/2014 - 15:15

I have been focusing a lot on security and privacy issues in this year's columns so far, but I realize some of you may expect a different kind of topic from me (or maybe are just tired of all this security talk). Well, you are in luck. more>>

Practical Tiny Core in the Fire Service

Linux Journal - Wed, 09/24/2014 - 16:14

I'm sure many of you have at least heard of Tiny Core Linux—legends of how small it is, how little it takes it to run a system with it and even now how it's been ported to run on Raspberry Pi. It's an esoteric minimalist distribution. more>>

Open Axiom

Linux Journal - Tue, 09/23/2014 - 15:56

Several computer algebra systems are available to Linux users. I even have looked at a few of them in this column, but for this issue, I discuss OpenAxiom. OpenAxiom actually is a fork of Axiom. Axiom originally was developed at IBM under the name ScratchPad. Development started in 1971, so Axiom is as old as I am, and almost as smart. more>>

Geolocation

Linux Journal - Thu, 09/18/2014 - 11:00

There's an old saying in the real-estate business that the three most important things in a property are location, location and location. We can assume this is still true when it comes to real estate, but it also is increasingly true when it comes to Web applications. more>>

Give new life to old phones and tablets with these tips!

Linux Journal - Wed, 09/17/2014 - 11:45

If you're like me (and you're a Linux Journal reader, so you may actually be like me), you probably rotate through your cell phones and/or tablets every couple years. These little devices are so convenient and have been consistently dropping in price, while their power continues to go up, so you may have a few older devices sitting in a drawer. more>>

Lucidchart

Linux Journal - Tue, 09/16/2014 - 13:03

I am a visual learner. When I try to teach something, I naturally like to use visual examples. That usually involves me working for hours to create flowcharts in Google Docs using the drawing program. Yes, it works, but it's a very cumbersome way to create a flowchart. Thankfully, I recently discovered Lucidchart. more>>

Linux Journal - Wed, 09/10/2014 - 16:16

Sometimes a new piece of code turns out to be more useful than its author suspected. Alejandra Morales recently came out with the Cryogenic Project as part of his Master's thesis, supervised by Christian Grothoff.

Montréal-Python 48: Incorrect jiujitsu

Montreal Python - Tue, 09/09/2014 - 23:00

It's time to go back to school and also for us, pythonistas from Montreal to have again our monthly meetups. We are changing a bit the tradition of having our meetup on the second Monday of the month and we are ready for an amazing edition full of great presenters.

This time, our friends of Shopify will welcome us on Tuesday, the 23th of September, at their amazing offices of the Saint-Laurent street (not so far away from the Benelux). It's an opportunity to meet the best of the python community in Montreal.

Don't forget that the call for speakers of PyCon is ending in less than a week, on September 15th. If you want more details, please have a look at the following page: http://montrealpython.org/2014/08/pycon2015-cfp/.

Flash Presentations (5 minutes each):
  • Rory Geoghegan: L Module of the month: pyp
  • Jordi Gutiérrez Hermoso: doitlive: shell demo magic for the masses Amaze your friends! Type like a hacker! Smash the keyboard and witness l33t h4xx0rz c0adz unfold before your eyes! Great parlour trick, and if you want something more boring, great way to do live shell demos
  • Simon Génier: Pyston, An open-source Python implementation using JIT techniques.
  • Mathieu Leduc-Hamel: Proctor, a swarm of Tor to protect your privacy
Main Presentations:
  • Thibault Cohen: Québec 24/7, le Québec supervisé. Québec 24/7 est un tableau de bord, Open source, basé sur des applications Python, présentant l'état Live du Québec.

  • Jonathan Doyle: Python Laser Lab in the Far North CANDAC RMR lidar (CRL) is a laser radar capable of measuring aerosol, cloud, and thermodynamic properties over Eureka, Nunavut (79.99N, 85.94W) operated remotely using Python. Two high powered Nd:YAG lasers are powered on, diagnostic tests performed, co-aligned to approximately 20 km, and then set to collect data via satellite link. Python is used (almost) exclusively to run the lidar system, including serial drivers, unittest suite with real-world conditions, XML-RPC/GUI or script based interfaces, babysitters, and data-analysis suite. In this talk I review the development and operation of the CRL highlighting the role of Python, as well as the problems we confronted while working in such a remote location.

  • Rory Geoghegan and Luis Rojas: Python and Docker How to get your python services running in docker.

  • Cameron Davidson-Pilon, Data Analyst at Shopify: Lifelines: Survival Analysis in Python While tools like linear regression and logistic regression moved from statistics to machine learning, the field of survival analysis was unfortunately left behind. This talk introduces survival analysis, how it is used, and a pure Python implementation: Lifelines.

Android Candy: Quit Thumbing Your Passwords!

Linux Journal - Thu, 09/04/2014 - 14:14

I use my phone more often to log in to on-line accounts than I use a computer. I can assure you it's not because typing passwords on a tiny keyboard is fun. For most of us, we just have instant access to our phones at any given time during the day. more>>

I'm writing this in a hotel room entered through two doors. The hall door is the normal kind: you stick a card in a slot, a light turns green, and the door unlocks. The inner one is three inches thick, has no lock and serves a single purpose: protection from an explosion. more>>

Getting Good Vibrations with Linux

Linux Journal - Tue, 08/26/2014 - 15:09

Vibrations and wave motions describe many different physical systems. In fact, most systems that dissipate energy do so through waves of one form or another. In this article, I take a look at gvb (Good ViBrations, http://www.pietrobattiston.it/gvb), a Linux application you can use to visualize and model wave motion and vibrations. more>>
