Next in our series of Python modules you should know is Scrapy. Do you want to be the next Google ? Well read on. Scrapy is a fast high-level screen scraping and web crawling framework, used to crawl websites and extract structured data from their pages. It can be used for a wide range of purposes, from data mining to monitoring and automated testing. You can use Scrapy to extract any kind of data from a web page, in HTML, XML, CSV and other formats. I recently used it to automate the extraction of domains and emails on the ISPA Spam Hall of Shame list, for use in a DNSBL.

There lots of big event on the Linux Planet calendar in any given year. Twice a year we get to celebrate a new Ubuntu release, its wacky name and its interesting new innovations.

Now having looked at the processor performance of the brand new Intel Core i7 3770K "Ivy Bridge" CPU, up now is our first look at the Intel HD 4000 "Gen7" graphics performance for the Ivy Bridge processors under Linux. Building upon what's turned into a huge success for Intel with their Sandy Bridge graphics with admirable performance and stable open-source Linux drivers, Ivy Bridge volleys Intel's Linux graphics capabilities into a whole new realm for those concerned about open-source graphics drivers.

In my previous installments, I described the success I've been having with compressing "Sita Sings the Blues" with the VP8 video codec, and at the end I had a video file. Then I converted the audio to get a FLAC copy of the soundtrack (opting to retain this rather than compress into Vorbis format). Now in this installment, I'll show how I used mkvtoolnix-gtk to build a complete MKV file with VP8 video, FLAC audio, and named chapters. The result is the complete "main feature" multimedia file that will form the core of the Lib-Ray prototype.

Although the Linux gamers are experiencing an impressing time today, even better times are waiting for them in the near future. While Steam for Linux is being developed by Valve at the moment, more Linux games than ever before are being published nowadays.

In the cloud computing market, upgrades are supposed to be instantaneous — with little or no impact to end-customers. But when it comes to OpenStack, the open source cloud computing environment, early adopters and cloud consultants are discovering that upgrading from one OpenStack release to the next release can sometimes be a difficult, time-consuming process. That’s where companies like Mirantis and Dell (promoter of Crowbar) potentially enter the picture. Here's why.

Roughly 1,000 technology experts gathered at an OpenStack technology conference last week, and some of those conference attendees believe OpenStack coupled with KVM (Kernel-based virtual machine) or Xen will trip up VMware within the next couple of years. But VMware will be tough to catch. Here's why.

Ubuntu 12.04 LTS Precise Pangolin final is almost out. The final release it scheduled to be out in the 26th of April 2012. After you actually get done with the installation, there would likely exist a heap of things you still need to take care of. This post will share some interesting insight and ideas about what you can and should do after a successful installation.

Intel is finally announcing the first Ivy Bridge processors this morning. I have been extensively testing out the Intel Core i7 3770K, the current high-end Ivy Bridge processor, for the past few weeks under Ubuntu Linux. I have been extremely pleased with the Intel Core i7 Ivy Bridge processor under Linux with its phenomenal performance, power efficiency, and new features. This article is the first of many looking at the Linux performance of the new Intel Ivy Bridge processors.

This coming Thursday marks the release of Ubuntu 12.04 LTS Precise Pangolin. Many users will download Ubuntu, try it and give up because of some small technical problem. Here is a list of tutorials and resources for Ubuntu beginners that I have found to be useful.

After all that theory and talking, let's start by building the code written through the last nine parts of this series. This part of our series might actually serve you even if you learned C someplace else, or if you think your practical side of C development needs a little strength. We will see how to install necessary software, what said software does and, most important, how to transform your code into zeros and ones.

If you follow the Humble Bundle series of game packages, or if you’re one of the unlucky individuals to get your mitts on its latest incarnation, you might be privy to a bit of controversy regarding the package. The controversy, simply put, involves the fact that all of the games in the package require defunct, unsupported Adobe products to function

Liam Fraser, creator of the popular Raspberry Pi Tutorials YouTube series and System Administrator for the Raspberry Pi Foundation shows us how to set up the Raspberry Pi and write our first Python ‘Hello World’ application…

Again PCLinuxOS delivers a release of impeccable quality in the face of a community that demands the highest standards. This distribution is becoming increasingly user-friendly, and the features continue to mount up.

Lars Torben Kremer proudly announced this weekend, on April 21st, the immediate availability for download of the final version of the Snowlinux 2 operating system.

The South Africa Internet service providers association (ISPA) maintains a list of known spammers dubbed the Spam Hall of Shame. The list is contains both domains as well as email addresses, this list is published on a webpage without downloadable formats. I extract the data from this web page and publish it in a DNSBL ispa.rbl.baruwa.net, i use this DNSBL in my SAAS mail security product. So anyone should be able to use it in a similar way to the other DNSBL's like spamhaus and spamcop etc.

This guide explains how to set up WebDAV with MySQL authentication (using mod_auth_mysql) on Apache2 on a Debian Squeeze server. WebDAV stands for Web-based Distributed Authoring and Versioning and is a set of extensions to the HTTP protocol that allow users to directly edit files on the Apache server so that they do not need to be downloaded/uploaded via http://FTP. Of course, WebDAV can also be used to upload and download files.

Latin America is a big place with many opportunities for KDE; major deployments of KDE software are proof. Over the years, groups of KDE developers have emerged in Argentina, Brazil, Chile, Colombia, Peru, and probably other places. These groups work together to make a better KDE. As we know, meeting and talking in person is important to strengthen the bonds in a community. So we decided to organize a Latin American meeting of KDE contributors following the lead of the first Akademy-br in 2009. Like Akademy-br, the first LaKademy will be similar to a sprint for developers and one for people interested in promoting KDE in this part of the world. The first LaKademy is taking place in the city of Porto Alegre, Brazil from April 27th to May 1st, 2012. People were invited from Brazil, Argentina, Peru, and Colombia. 12 known KDE contributors have confirmed their presence, along with 6 newcomers. Current KDE contributors recommended newcomers based on their abilities and their potential to become long-time KDE contributors. read more

JBackpack is a personal backup program. It features incremental backups, network transparency and encryption. JBackpack uses rdiff-backup for all backup and restore functions, SSHFS and SMB to access remote file systems and EncFS to encrypt backup destination directories.JBackpack uses rdiff-backup for all backup and restore functions. The most interesting feature of rdiff-backup is incremental backups.

It doesn't happen often here in the Linux blogosphere that FOSS fans agree unanimously on -- well, on pretty much anything. Truth be told, there's generally good reason for the dissension. Take Microsoft's latest maneuvers, for example -- are they good news? Bad news? It's not always easy to tell. Last week, however, one of those rare announcements was made that brought universal joy to Linux aficionados around the globe.
