In this tutorial I will describe how to install and configure mod_deflate on a lighttpd 1.4 web server on Debian Etch. mod_deflate is included by default in lighttpd 1.5, but not in 1.4 where mod_compress is used instead. The advantage of mod_deflate over mod_compress is that it can compress static and dynamic files (such as PHP files), whereas mod_compress can compress static files only. The lighttpd version coming with Debian Etch is 1.4.13, so we have to patch it to support mod_deflate. mod_deflate allows lighttpd to compress files and deliver them to clients (e.g. browsers) that can handle compressed content which most modern browsers do. With mod_deflate, you can compress HTML, text or XML files to approx. 20 - 30% of their original sizes, thus saving you server traffic and making your modem users happier.
No other hardware nowadays supports GNU/Linux as weakly as wireless network adapters. Between the constant release of new models and major vendors who are uninterested in supporting the operating system, free drivers for wireless cards are next to impossible to reverse engineer. Nor can you find many retailers willing to customize laptops as readily as they do workstations. In this situation, ndiswrapper and the Broadcom firmware cutter provide a functional, if not always satisfactory, solution.
For the third year in a row, the geeks will gather in Bickford Park to eat drink and be nerdy. This year, just like last year, non-geeks and people who just like penguins, are invited. A computer swap meet is planned along the south edge of the park (tentatively 10am - 3pm) where we have the luxury of having a truck come by ,later in the day, to pick up the detritus. So bring all your computer junk and tell all your friends. The gathering starts at 11:00 hours and will end at 20:00 hours.
The BBC iPlayer has been a hot topic on everyone's lips. It's late, doesn't work very well yet, presents some ISPs with a big economic problems, and is limited to Windows XP users running Internet Explorer. That last point has proven particularly sticky for the Beeb's spinners in the last few weeks, but in reality reveals as much about Microsoft's plans for DRM as it does about any supposed "corruption" of the BBC by some Gates-backed Sith.
Swisscom IT Services, a subsidiary of the largest telecommunications provider in Switzerland, is using a wide variety of solutions from Red Hat for its Linux software infrastructure. Swisscom is using Red Hat Enterprise Linux, Red Hat Cluster Suite, JBoss Enterprise Platform and other Red Hat offerings in multiple data centers. It provides outsourcing information technology services to more than 50 customers.
A U.K.-based embedded software consultancy says it recently implemented a Linux driver and other software for a marine-based military application involving high-speed, fiber-optic networking. Pebble Bay Consulting Ltd. says it helped U.K.-based defense contractor Kaon implement an "embedded Linux" solution for an unspecified military customer. Pebble Bay's role reportedly included re-writing a Linux driver, creating an FPGA (field-programmable gate array), interface, and creating a user-space API (application programming interface) library.
Open source is changing not just how companies make software, but how they sell it. Alfresco's Matt Asay explains the new sales cycle and the skills that today's software sales people need to close deals.
In this 12-minute video watch and learn the order of magnitude simplification that XForms can offer to the development of applications that interact with users to collect the XML data that drives back-end business processes.
In Part 1 of this series, I explained my reasoning behind creating an open source strategy. In Part 2, I will discuss our progress. Our first step was to create an inventory of the open source products that we use at my IT shop. We have a few areas within the organization that were early adopters of OSS and have a variety of products in use. When polling the staff for OSS products, I expected to find between 20-30 actively being used. I was shocked to find that we have around 100 different OSS products in our inventory (not including the ones packaged within proprietary closed software products). What an eye opener!
Very little, in my opinion. While Matt Asay sees the deal as "a big win for open source... mostly because it pegs the value of an open source company quite high" I'm not sure that's true in this case. I've got to agree with Raven Zachary over at The 451 Group when he writes that "It wasn’t open source that provided the 150x multiplier." Yes, the open source Xen project is at the heart of XenSource's business, but Citrix did not pay $500m for the Xen project. As Savio Rodrigues notes if Citrix was after Xen it could have got its hands on it for a lot less than $500m
Linux buffs tend to scoff at one of the major reasons that Windows users like me haven't switched yet: We don't want to give up our favorite applications. With countless open-source options, plus a rising number of commercial apps for Linux, their argument goes, we can certainly find a replacement for whatever software we're running on XP or Vista. I spend a good chunk of keyboard time dealing with text in varied forms, so one of my top requirements is a robust application that can elegantly handle plain ASCII text and rudimentary HTML.
The offer of pre-installed Linux by mainstream PC makers doesn't mean the open-source operating system is poised to sweep aside Microsoft’s; but while its cost advantages may never be compelling, finance departments must prepare to consider the merits of switching their own operations to Linux – and to hear a stronger case for its company-wide adoption.
Some quarters in the software industry still carry a bias against the credibility of open source security applications. Open source network gateway developer Untangle did not expect to find its request for certified testing of the popular open source virus security product ClamAV shunned. When it was, Untangle decided to do its own test. "We found that ClamAV was the quickest with the least drained resources. We also noticed that same thing with other types of open source security products," Dirk Morris, Untangle's founder and CTO said. "I didn't believe that open source was better. Now I do."
A new business model has emerged based on the concept of products that are community-based and available with the source code at no cost – the open source movement. The open source effect is now making itself felt in the integration marketplace, where Mule from MuleSource has become established as a popular ESB and integration platform. As businesses look to become less dependent on software vendors to solve their integration issues there is a groundswell of support for open source solutions.
SCO may have lost a major legal battle with Novell, but it refuses to admit that it may have lost its Linux IP war. When the U.S. District Court in Salt Lake City ruled that Novell, and not SCO, owned Unix's intellectual property, many SCO watchers assumed that it was game over for SCO's long war against Linux and the companies--Novell, IBM and Red Hat--that supported it. Never one to stay down for long, despite numerous setbacks, SCO CEO Daryl McBride insisted in a letter to SCO's partners and customers that it's not down for the count.
It has been said there is no such thing as a 'true' Free Software business. Blue GNU interviewed the Ada Core Technologies team to learn about the company that has been a 'true' Free Software business for over 20 years. Ada Core is one of a few businesses listed as such by the Free Software Foundation/GNU Project.
Yes, a judge has confirmed that Novell owns the copyrights to the Unix operating system, but that doesn't mean the company plans to start suing people for using Linux. It will leave such behavior to companies that don't own the copyrights. Like SCO. "We have absolutely no intention of using our Unix copyright ownership to attack Linux," Novell spokesperson Bruce Lowry told The Reg. "We've had those copyrights for the past 14 or 15 years. The fact that the court has reaffirmed them doesn't mean we're now going to change the way we operate. We've never indicated we would use those copyrights against Linux - and we wouldn't. In fact, we want to defend Linux."
Linux Mint, a community Linux distribution that includes some proprietary elements for a better "out of the box" user experience, is now available in an edition with KDE as its desktop environment. This 3.0 release is based on Bianca KDE Mint 2.2. Like that edition, Cassandra KDE Community Edition is compatible with all Ubuntu 7.04 Feisty Fawn repositories. Instead of the GNOME 2.18 interface that Linux Mint 3.0, Cassandra, the KDE version uses, the KDE 3.5.6 desktop. For those who want to live life on the 3D side of the Linux desktop, it also comes with Beryl 0.2.1 and the Beryl-Manager.
If you’ve been working with Linux very long, you’ve probably encountered dd, the deceptively simple utility for copying a stream of data from here to there. You may have used it to zero a disk before letting it leave the building, to benchmark io hardware by writing a certain number of bytes, to put a disk image on a floppy or usb drive, or even to back up an entire disk.
When Sun looks to highlight the strongest features of the Solaris operating system, DTrace always appears near the top of the list. Your editor recently had a conversation with an employee of a prominent analyst firm who was interested, above all else, in when Linux would have some sort of answer to DTrace. There is a common notion out there that tracing tools is one place where Linux is significantly behind the state of the art. So your editor decided to take a closer look.
