Linux Graphics News

Linux Journal - Sat, 04/26/2014 - 09:00

At the start of this quarter we looked at how 2013's graphics developments were more incremental than revolutionary, perhaps with the need for LTS stability in mind. Things are looking quite different this year, with several major changes quietly under way. more>>

Python Workshop: Text Analysis Introduction

Montreal Python - Tue, 04/22/2014 - 15:00

With social networks and massive digitalization projects, nowadays the Internet has lots of data ready for analysis, at the hand of whoever wants to work with it. With these data, we can study social movements, the evolution of a concept or the public interest for a specific brand -- in fact, we can study everything that uses text. For massive datasets, we use automatic learning and text mining algorithms to extract concepts and associations to analyze.

In collaboration with the Laboratoire d'analyse cognitive de l'information (LANCI), Montréal-Python invites you to discover these text analysis methods, in English. Only basic knowledge of Python programming is required.

In this workshop, you'll learn:

  • the different steps of computer assisted text analysis
  • the fundamental concepts of distributed linguistics and its impact on text analysis
  • to use the main techniques of text preprocessing
  • to cut a text and regroup it by similar segments
  • to extract the representative terms of one or many textes

The workshop will be:

  • Thursday, the 20th of March 2014
  • from 6:00 PM to 9:00 PM
  • at the CRIM

Bring your laptop or pair up with someone else.

You'll need Python running on your computer, with these modules installed : pattern, numpy and scipy. It's also recommended to have IPython installed.

Generally speaking, if you want to have fun with the code in Montréal-Python workshops without loosing your time with configuring your machine and if you want a guaranteed support by the assistants, do yourself a favor and get a developer workstation on Ubuntu by following these simple steps.

If you need help to setup your development environment, we'll be there to help before the workshop, starting at 5:30 PM.

30 places are available, register on Eventbrite.

See you next Thursday!

Quantum Cryptography

Linux Journal - Tue, 04/22/2014 - 12:32

Classical cryptography provides security based on unproven mathematical assumptions and depends on the technology available to an eavesdropper. But, these things might not be enough in the near future to guarantee cyber security. We need something that provides unconditional security. We need quantum cryptography. more>>

Non-Linux FOSS: Angry IP

Linux Journal - Wed, 04/16/2014 - 16:12

The de facto standard for port scanning always has been the venerable Nmap program. The command-line tool is indeed very powerful, but I've only ever seen it work with Linux, and every time I use it, I need to read the man page to figure out the command flags. more>>

Encrypting Your Cat Photos

Linux Journal - Tue, 04/15/2014 - 14:28

The truth is, I really don't have anything on my hard drive that I would be upset over someone seeing. I have some cat photos. I have a few text files with ideas for future books and/or short stories, and a couple half-written starts to NaNoWriMo novels. It would be easy to say that there's no point encrypting my hard drive, because I have nothing to hide. more>>

Speed Test for Nerds

Linux Journal - Thu, 04/10/2014 - 14:46

Most people with Internet access in their houses have visited a speed-test Web site to make sure they're getting somewhere close to the speed they're overpaying for. I'm paying more than $100 a month for my business-class connection from Charter, so on a regular basis, I make sure I'm getting the advertised speed. more>>

It's full of stars!

Waglo - Fri, 02/26/2010 - 20:25
J'ai décidé de mettre un peu plus de contenu sur ma page d'accueil, question de rendre ça un peu plus gai. J'utilise Google Reader depuis quelques semaines et j'essaie de bien classer mes découvertes sauf que je ne peux pas faire ça tous les jours. Ce que je vous propose sur ma page d'accueil c'est un échantillon de ce que je star, c'est à dire des trucs que je vais lire plus tard et classer. Voilà la version brute.

Little Google Buzz trick while you wait

Waglo - Wed, 02/10/2010 - 13:26

If like me you’re not Buzzed yet, you can have some sort of preview. First, go to your Google Mail labs, enable the Multiple inboxes experiment. Next, in your settings, hit Multiple inboxes and add “is:buzz” (no quotes) to one of the empty panes. Voilà, now you have direct access to your Buzz, directly from your Google Mail inbox.

UPDATE: 12 hours after posting this and I just noticed a silly mistake. Where it said to use “is:spam”, it really should have been “is:buzz”, obviously.

Trick #2: Now you’ve got the Buzz and you find out some are actually polluting your inbox. There’s a fix for that too. Create a filter by putting “is:buzz” in the “Words:” field. When you hit the “Next” button, you’ll get a warning but you can disregard that, it will work. On the next page, either Archive (skip the inbox) or Delete those mails and voilà, problem solved.

Trick #3: To reduce the Buzz noise from your Google Mail: create a filter to remove Buzzes from your Sent Mails with “is:sent -{is:buzz}” (no quotes), labelling that “Emails Sent” and hiding the default “Sent Mail” label.

Google Buzz

Waglo - Tue, 02/09/2010 - 13:35

Sure, just when I decide to leave Facebook, Identica, Twitter and Friendfeed behind, Google comes out with this!

Google Buzz API documentation

Google Buzz API

Google Buzz is their new social media tool, real time, for public and private sharing and works directly from Google Mail.

You can find out more about it by reloading ReadWriteWeb’s live blogging session continuously.

More links:

I was planning a couple of posts:

  • Why I left Facebook, Identica, Twitter and Friendfeed and why you probably shouldn’t
  • My life in Google’s hand

Hoping those will explain what’s happening with me recently.

Observatoire d’informatique libre québécois | Logiciel Libre, Free Software et Open Source au Québec

Waglo - Mon, 02/08/2010 - 11:25

J’ai changé le nom de domaine pour l’Observatoire de l’informatique libre québécois : Observatoire d’informatique libre québécois | Logiciel Libre, Free Software et Open Source au Québec. J’espère ainsi lui donner une identité plus précise. C’est un message d’André Cotte sur la liste de FACIL où il disait

« Quand on peut s’intégrer dans un site d’agrégation de flux comme
Informatique libre
, on a le meilleur des deux mondes : son blogue et la
diffusion. »

qui m’a fait penser à ça.

L’ancien domaine fonctionne toujours, bien sûr, mais tout le traffic est maintenant redirigé vers le nouveau nom,

Je suis toujours ouvert à vos suggestions pour améliorer le site, ainsi qu’à vos dons pour aider à réaliser ces suggestions.

Animated news, hey, that’s my idea!

Waglo - Tue, 02/02/2010 - 17:03

Slashdot has a story today about animated news as this clip shows:

I’m only mentionning it because it’s something I wanted to do maybe five years ago and car accidents was my first thought. Without the Tiger Wood caracter of course. You can read more about this in The blurry lines of animated ‘news’ on the CNN website.

Which reminds me of another idea I had: why not make a site to predict the stories that will appear on Slashdot tomorrow or in a couple of days? It could even become a fun gambling site. Who knows…

The pen as a multimodal interface

Waglo - Sat, 01/23/2010 - 17:15

I’ve long been thinking about a cool gadget I’d like to have. It might remind you of the set of pen computers if you’ve seen it, but what I want is much simpler, just one pen but probably hooked with bluetooth to other devices.

What is the quickest way to play a song when you know its name? If you’ve got a keyboard, typing its name is the obvious choice. If you have a GUI, drilling down and selecting it (going through genres, artists or years maybe) is the way to go. But if all you have is a pen, why not just write it out? You want to pause it? Two parallel vertical lines should do the trick, and obviously a triangle pointing right will have it play again. Where does the sound come from? Bluetooth headset or maybe even a tiny speaker directly on the pen. Or maybe it’s controlling some remote computer. Where are the songs stored? Probably not on the pen, although we can easily imagine a pen holding 3000 songs (say, 16 GiB). Lots of possibilities.

Hmm, how did I come up with 3000 songs? Say a song is 5 MiB for a cheap MP3 encoding. Take your new super pen, and write it out: 16,000,000,000 / 5,000,000 (with commas, spaces, or using GiB and MiB units, it doesn’t really matter), finish with an equal sign and what happens? The pen can tell you the answer, using that tiny speaker and its voice synthesizer. Maybe we could also add a small display on the side of the pen, or even have the output sent to your watch screen. The possibilities are endless!

How else do you think this could be useful? Maybe the pen could provide some haptic response (say, to correct your spelling). What else?
