Review of Ubuntu 6.10 Edgy Eft

Filed under
Reviews
Ubuntu

Most Linux users have heard of the popular Ubuntu Linux distribution and many know how stable the OS is on desktop computers. But for the growing Linux laptop user segment, how well does the latest version of Ubuntu recognize specialized laptop hardware and perform on their portable device? Today I'm taking a look at Ubuntu 6.10 Edgy Eft on Open Addict's DELL XPS M170 test laptop.

FSF praises Sun's commitment to OSS

OSS

The Free Software Foundation (FSF) announced yesterday that they welcomed the public commitment from Sun Microsystems to distribute its proprietary Java platform under the GNU General Public Licence (GPL).

Ensuring network interfaces remain named consistently

Filed under
HowTos

If you have more than one network card, there is no guarantee that eth0 when you first boot up remains eth0 in the next boot. It could swap with eth1. This can happen especially if the cards are the same chipset, I reckon. If you change kernels or switch to using something like hotplug or udev you can also find the same problem.

LinuxBIOS - A truly GPLed Free Software BIOS

Filed under
Software

A BIOS is an acronym for Basic Input Output System and is the starting point of the boot process in your computer. But one of the disadvantages of the proprietary BIOS which are embedded in most PCs is that there is a good amount of code which is used in it to support legacy operating systems such as DOS and the end result is a longer time taken to boot up and pass the control to the resident operating system.

PS3 Linux: Dual Boot Instructions & Blu-ray disc mounting supported!

Filed under
HowTos

A day after the PS3 Japan launch madness, all of us here at QJ had a chance to look back and see exactly what info we had missed. I had the responsibility of checking out the Linux side of things. And while the article which I wrote yesterday was pretty much spot on, there's a few more things which I could get out of the documents released.

Installing From Tarballs

Filed under
HowTos

We usually download linux programs through package handling tools such as yum and apt-get. Download programs through package handling tools is easy, but not all programs is available in your Linux distribution repository. Sometimes, we need to download the source code, compile and install manually.

Control is the real open source advantage

Filed under
OSS

In all the blah-de-blah over the moves by Oracle and Microsoft into open source a very important point is missing, namely the motivation of enterprises in moving toward open source. It's not the cost savings. It's not the community. It's not the name of the vendor.

Mapping the universe with open source software

Filed under
Software

Astronomers at New York City's Hayden Planetarium and Rose Center for Earth and Space think space exploration should be easily accessible to anyone. To make that possible, they offer an interactive atlas of the universe that anyone can download for free.

Microsoft's Interoperability Trust Problem

Filed under
Microsoft

Yesterday, Jason Matusow, Microsoft's director of corporate standards, blogged about trust. Surprise. Surprise. He found that some customers question Microsoft's sincerity around interoperability and licensing.

Recover from CHMOD -R 777

Filed under
HowTos

A linux administrator asked a question on how to recover from CHMODing the whole file system to 777. I had also screwed my system the same way two days earlier and no solution was insight (#chmod -R 777 / ) and my Boss was angry. A solution submitted blew me off. Very simple but it worked like magic!

Simple Package management with Synaptic Package Manager in Ubuntu

Filed under
HowTos

Synaptic is a graphical user interface (GUI) for managing software packages on Debian-based distributions. If you are using Debian or Ubuntu you will easily find Synaptic in the System Tools menu or in the Administration menu. Now we will see how to add repositories,install,remove and update software packages.

Ubuntu Developer Summit, Mountain View

Filed under
Ubuntu

We were new to the Ubuntu Summit way of doing things but figured it out quickly. I think we all felt we should be doing more to justify our presence, but hopefully we provided at least some valuable input and advice, and some of us even started implementating specifications. But most of the specifications being considered were lower down in the system, dealing with things such as drivers, devices, X, etc.

VMware and Xen Management with BixData

Filed under
HowTos

What Does Free Software Really Cost?

Filed under
OSS

You've probably seen the many articles infesting computing publications that blather on about comparing TCO (Total Cost of Ownership) and ROI (Return on Investment) for Linux and Windows, and trying to figure out which one costs less to run. Let's set up a gnarly Linux vs. Windows DeathMatch Arena with two hypothetical admins - one for Linux, one for Windows.

Interview with Brian Brazil and Paul O'Malley of gNewSense

Filed under
Interviews

Irish Free Software developers Brian Brazil and Paul O'Malley have developed a new distribution, appropriately named gNewSense. Made with the philosophy of Debian and the structure of Ubuntu, it aims to be the freest distribution out there. Linux Online is grateful to Messrs. Brazil and O'Malley for taking time out of their busy schedules to answer a few questions about their project.

When Linux trumps Unix and vice versa

Filed under
Linux

According to recent studies, two thirds or more of IT organizations are considering a migration to Linux. But obviously any migration is no trivial matter. If your organization is thinking about migrating to Linux, plan to take a hard look at the realities before you get too far into the process.

  • How Linux Frustrated Me Into Loving It
    I have been very interested in Linux since my entry into the Wonderful World of Unix in 2006. I found Ubuntu and installed it on a crappy Dell desktop computer I was given when I was doing online schooling. The computer originally came with Windows, and one day while I was browsing, I decided to search for “alternative to Windows.” Linux popped up right away. I had never heard of Linux before, but after voraciously reading article after article, I decided Linux was the path for my future.
  • HP Chromebook 13 is a business-focused Chrome OS laptop with USB-C
    In the grand scheme of things, Chrome OS is hardly a major player from a desktop market share perspective -- for now. With that said, the Linux-based operating system has captured the hearts and minds of many consumers. It has matured quite a bit too, becoming a viable Windows alternative for home users. Actually, it is a great choice for some businesses too -- depending on needs, of course.
  • Summary: Linux Scheduler: A decade of wasted cores - Part 1 - What is NUMA ?
    Last month, a research paper with title 'The Linux Scheduler: a Decade of Wasted Cores' was trending on the front page of HN. As an individual who is interested in Systems, I thought it would be good idea to read this 16 page research paper. I spent a good amount of time learning about different topics which were involved in it. This is the first post in the series in which I will try to summarize the paper.
  • Vulkan 1.0.12 Specification Update Adds VK_AMD_rasterization_order
  • GTK+ 3.22 Is Working On An OpenGL Renderer & Scene Graph
    Matthias Clasen of Red Hat has written an update about changes to GNOME's GTK+ tool-kit for the 3.20 cycle but he also mentions some of the exciting work that's brewing for GNOME/GTK+ 3.22. Clasen's latest blog post covers some of the recent internal changes to GTK+ CSS, theme changes, various changes facing application developers, and more. Those interested about the GTK+ tooling changes can read the blog post.
  • Bunsenlabs Rc2
  • April is almost gone
    The second one was the release of pre-release isos of Mageia 6 and OpenMandriva Lx 3. I must say that both distros are doing a great job; the systems performed so well that they did not seem beta versions to me. I did not like Plasma 5, though... I am sure the KDE team is doing a great work, but I truly do not see what the point of this tablet-ready interface is. After all, KDE missed the tablet train (the Vivaldi tablet never saw the light of the day) and tablets are already in decline...
  • New BlackArch Linux version released, now provides 1400 pentesting tools
    BlackArch Linux version 2016.04.28 released for ethical hackers and security researchers with 1400 pentesting tools
  • Manjaro 16.06 - third preview released
    It took us almost another month to prepare this third preview of our upcoming stable release we call Daniella. The Xfce edition remains our flagship offering and has received the attention it deserves. Few can claim to offer such a polished, integrated and leading-edge Xfce experience. We ship Xfce 4.12 with this release of Manjaro. We mainly focused on polishing the user experience on the desktop and window manager, and on updating some components to take advantage of newly available technologies such as switching to a new theme called Maia, we already using for our KDE edition.
  • IoT Past and Present: The History of IoT, and Where It's Headed Today [Ed: just devices with a network stack. Nothing new.]
  • 1btn – an Open Source Dash
    The availability of cheap radios, omni-present WiFi and powerful web services means the IoT wave is here to stay. Amazon got into the act with its “do only one thing” Dash button. But a more interesting solution would be an IoT “do it all” button.
  • No Time to Panic as One Quarter Shows Minor Dip in Smartphone Sales - Total Smartphone Market Will Grow This Year (and here's why)
    We now have the Q1 numbers from Strategy Analytics and IDC, the two last remaining of the classic four big smartphone industry analyst houses we used on this blog to calculate the industry average of the total market size, back when the 'smartphone bloodbath' started six years ago. And both SA and IDC are in exceptional, near-perfect agreement on the exact size of the market, we get a total smartphone market for Q1 at 334.8 Million units. That is down 18% from the Christmas sales Quarter (normal that Q1 is down) but for the first time ever in this industry, the YEAR-ON-YEAR comparison of Q1, so the January-March quarter last year 2015 vs now, is down. This has not happened in the smartphone industry in any YoY period. And some are now talking about 'peak smartphone'. That number COULD be a signal that smartphone industry growth has stalled and now peaked and smartphone sales will either plateau flat, or decline into the next year(s).
  • GhostBSD 10.3 Alpha Released With ZFS File-System Support, MATE 1.12
    The first alpha release was made available this weekend of GhostBSD 10.3 Alpha 1, a desktop focused operating system built atop FreeBSD 10.3.
  • 3D Printer Crowdfunding projects
    Like every Kickstarter project, there is a risk. But I think that Trinus appears to be a good project, we need to wait to the launch and review a real machine to know if it worth it. Also, the Youtube Channel Maker’s Muse, made a review of the project and the company Konama, creators of Trinus, sent him a the 3d printer and he currently makes the review of this printer that pledged more then 1 million dollars on KickStarter.
  • Refactoring the open-source photography community
    Generally speaking, most free-software communities tend to form around specific projects: a distribution, an application, a tightly linked suite of applications, and so on. Those are the functional units in which developers work, so it is a natural extension from there to focused mailing lists, web sites, IRC channels, and other forms of interaction with each other and users. But there are alternatives. At Libre Graphics Meeting 2016 in London, Pat David spoke about his recent experience bringing together a new online community centered around photographers who use open-source software. That community crosses over between several applications and libraries, and it has been successful enough that multiple photography-related projects have shut down their independent user forums and migrated to the new site, PIXLS.US.
