Understanding your Linux daemons

Filed under
HowTos

A Unix daemon is a program that runs in the “background,” enabling you to do other work in the “foreground,” and is independent of control from a terminal. Daemons can either be started by a process, such as a system startup script, where there is no controlling terminal, or by a user at a terminal without “tying up” that terminal as the daemon runs. But which daemons can you safely play with? Which should you leave running?

Open source becomes political wedge issue

Filed under
OSS

Last year, in Massachusetts, we saw open source being used as a political football. But the underlying issue in that case was technological, the state's adoption of ODF as a standard format. Now, in England, we're again seeing open source being used by politicians.

Using truecrypt-intaller to help install Truecrypt for Debian

Filed under
HowTos

Truecrypt is an Open Source disk encryption software which uses a concept of containers to store encrypted data. The nice thing about Truecrypt is that the containers (or volumes) can be read transparently under Linux and Windows. Here are step by step instructions how to use the truecrypt-installer utilities to get Truecrypt running with minimum of effort.

Use the “CUBE” with XGL and Compiz on your Suse Laptop

Filed under
HowTos

I got my laptop on Friday two weeks ago. One of the first things I did was partition the drive, and install OpenSuse 10.2, 64bit version. The installation went smoothly and everything (including WLAN) worked perfect. In this workshop I want to explain the installation of the 3D cube using XGL and Compiz.

FAA Ponders Switch to Linux, Premier Apps

Linux dominating the desktop…an impossible dream?

Filed under
Linux

I’m starting to think that I have to agree with Paul Thurrott: this year will not be the “Year of Desktop Linux”…again. While some people have some idea that Linux has the tools to do as such today, a better example to compare to is probably Apple’s OS X. OS X has all the tools to rapidly and easily take over the desktop world. But like Paul Thurrott quoted, OS X market share is between 2.5% and 4%.

Linux server shipments shrink as enterprises consolidate, virtualize data centers

Linux

Linux server revenue grew slightly in the fourth quarter of 2006, according to the latest research from IDC. But while overall Linux usage is growing, the number of physical Linux servers being shipped to enterprises may be suffering due to the trend of virtualization.

Management 'scared' by open source

Filed under
OSS

Fear is stalking the corridors of corporate power, as executives sweat over the legal exposure caused by developers using open source software. And the suits are resorting to play-it-safe legal advice and draconian management techniques in a vain attempt to stop open source crossing their frontier.

Using Cscope and SilentBob to analyze source code

Filed under
HowTos

When you start learning the source code of an unfamiliar project, you don't have the knowledge of its structure or the meaning of specific functions, classes, and units in the project. You can use tags to browse for definitions, but it's hard to get an overall picture by just looking through every definition one by one. Cscope and SilentBob are two tools that can help you analyze unfamiliar source code.

PCLinuxOS 2007 (beta 2) - Review

PCLOS
Reviews

I have used PCLinuxOS since version .8 and have always found it easy to use and aesthetically appealing. Being based on Mandriva might help PCLinuxOS' cause as Mandriva has been and continues to be a system new Linux users can migrate to with little to no learning curve.

Red Hat to set up open-source software store: source

Red Hat Inc. plans to create a Web store to boost sales of its own open-source software and of compatible open-source products from other companies, a person familiar with the plan said on Thursday.

Howto: Mounting without sudo

Filed under
HowTos

This had been bothering for some time. On a system without an automounting “solution,” which I don’t usually like because they involve daemons and message subsystems and whatnot, mounting an external drive such as a USB key can be problematic. Mounting requires sudo, but sudo inflicts root ownership on the target, which makes it inaccessible to a non-root user, short of using sudo over and over again.

Firefox challenging IE for dominance in US SMBs

Moz/FF

A survey of 140,000 small to medium-sized business (SMB) users has revealed that the Mozilla Firefox browser is now almost on equal footing with Microsoft's Internet Explorer in the SMB market sector. What's more, the gap is narrowing dramatically every month.

In favor of the new gnome control center

In my preview of Ubuntu 7.04 I argumented strongly in favor of the new Gnome control center. But comments on that preview suggested that most of the Ubuntu users dislike it. Let’s have a look at the benefits of both and try to decide what way Ubuntu should go.

Upstart Plans to Ease Linux Management

Linux Mint -- A Linux from the land of green worth its name

Ubuntu

Linux Mint. Just like its parent distro Ubuntu an enigma. Born in Ireland out of a frustration of what the current distros included, or better yet lacked, this little package has taken the Linux community by storm. A quick check on Distrowatch says that it came into light there November 14, 2006 and in that time has risen to the near top ten (when looking at the last 30 days) and spent some time within the top ten following the latest release Bianca (2.2).

Where are the Linux admins?

Filed under
Linux

In the battle to spread the use of GNU/Linux, it is often forgotten that education has to be the starting point. People need to be educated to the point where they come to demand decent behaviour from an operating system; companies need educated admins to keep GNU/Linux systems running.

Linux Mint freshens Ubuntu's palate

Ubuntu

Ubuntu is a strong desktop distro, but it falls short for some users in a few areas. Where are the multimedia codecs and DVD support, and what's with all the brown, for heaven's sake? If you'd like multimedia support with a minty fresh theme, try Linux Mint 2.2, an Ubuntu-based distro that throws in support for Flash 9, Windows Media Format, DVDs, MP3s, and troublesome wireless cards.

Announcing Video Player: Codeine for KDE4/Phonon

KDE

Here is the official announcement of a video player I'm calling Video Player. If your a Codeine user and it looks familiar, thats the idea. Codeine is the "usability focus, simple video player" that Max Howel developed using KDE3 and xine-lib. So I asked Max a couple of weeks ago if I could port Codeine to KDE4 and Phonon.

LWN at GUADEC

  • Flowgraphs in GTK+
    At GUADEC 2016 in Karlsruhe, Germany, Daniel "grindhold" Brendle presented his work developing a new library and widget set that will allow GTK+ applications to implement flowgraphs in a standard manner. The widget set would enable applications to provide interactive widgets for linking filters and other block-oriented components—a type of interface many applications currently need to reinvent on their own. Flowgraphs, Brendle explained, are a general-purpose diagramming technique that many people will recognize from textbooks and other printed matter. They show how objects, information, and signals flow through some sort of process. Biology textbooks use them to illustrate circulation in the body, technical manuals use them to show how a manufacturing process runs, and so on. In software, he said, they are most familiar as the node-and-pipe diagrams that illustrate signal processing or data filtering.

  • St. Jude stock shorted on heart device hacking fears; shares drop
    The stock of pacemaker manufacturer St. Jude Medical Inc (STJ.N) fell sharply on Thursday after short-selling firm Muddy Waters said it had placed a bet that the shares would fall, claiming its implanted heart devices were vulnerable to cyber attacks. St. Jude, which agreed in April to sell itself for $25 billion to Abbott Laboratories (ABT.N), said the allegations were false. St Jude shares closed down 4.96 percent, the biggest one-day fall in 7 months and at a 7.4 percent discount to Abbott's takeover offer. Muddy Waters head Carson Block said the firm's position was motivated by research from a cyber security firm, MedSec Holdings Inc, which has a financial arrangement with Muddy Waters. MedSec asserted that St. Jude's heart devices were vulnerable to cyber attack and were a risk to patients.
  • BlackArch Linux ISO now comes with over 1,500 hacking tools

  • Big Blue Aims For The Sky With Power9
    Intel has the kind of control in the datacenter that only one vendor in the history of data processing has ever enjoyed. That other company is, of course, IBM, and Big Blue wants to take back some of the real estate it lost in the datacenters of the world in the past twenty years. The Power9 chip, unveiled at the Hot Chips conference this week, is the best chance the company has had to make some share gains against X86 processors since the Power4 chip came out a decade and a half ago and set IBM on the path to dominance in the RISC/Unix market. IBM laid out a roadmap out past 2020 for its Power family of processors back at the OpenPower Summit in early April, demonstrating its commitment the CPU market with chips that are offer a brawny alternative to CPUs and accelerators compared to the Xeon and Xeon Phi alternatives from Intel and the relatively less brawny chips from ARM server chip makers such as Applied Micro and Cavium and the expected products from AMD, Broadcom, and Qualcomm. We pondered IBM’s prospects in the datacenter in the wake of some details coming out about next year’s Power9 processors, which IBM said at the time would come in two flavors, one aimed at scale-out machines with one or two sockets and another aimed at scale up machines with NUMA architectures and lots of sockets and shared memory.
  • ARM Announces ARM v8-A with Scalable Vector Extensions: Aiming for HPC and Data Center
    Today ARM is announcing an update to their line of architecture license products. With the goal of moving ARM more into the server, the data center, and high-performance computing, the new license add-on tackles a fundamental data center and HPC issue: vector compute. ARM v8-A with Scalable Vector Extensions won’t be part of any ARM microarchitecture license today, but for the semiconductor companies that build their own cores with the instruction set, this could see ARM move up into the HPC markets. Fujitsu is the first public licensee on board, with plans to include ARM v8-A cores with SVE in the Post-K RIKEN supercomputer in 2020.
  • The Sad State of Docker
    I have always been a big fan of Docker. This is very visible if you regularly read this blog. However, I am very disappointed lately how Docker handled the 1.12 release. I like to think of version 1.12 as a great proof of concept that should not have received the amount of attention that it already received. Let’s dive deep into what I found wrong. First, I do not think a company should market and promote exciting new features that have not been tested well. Every time Docker makes an announcement, the news spreads like a virus to blogs and news sites all over the globe. Tech blogs will basically copy and paste the exact same procedure that Docker discussed into a new blog post as if they were creating original content. This cycle repeats over and over again and becomes annoying because I am seeing the same story a million times. What I hate most about these recent redundant articles is that the features do not work as well as what is written about them.
  • Containers debunked: DevOps, security and why containers will not replace virtual machines
    The tech industry is full of exciting trends that promise to change the face of the industry and business as we know it, but one that is gaining a huge amount of focus is containers. However, problems lie with the technology and threaten to root itself deep in the mythology about it, namely the misconceptions over what the technology is, what can be done with it, and the idea that they replace virtual machines. Lars Herrmann, GM, Integrated Solutions at Red Hat spoke to CBR about five common misconceptions, but first the benefits. Herrmann, said: “Containerisation can be an amazingly efficient way to do DevOps, so it’s a very practical way to get into a DevOps methodology and process inside an organisation, which is highly required in a lot of organisations because of the benefits in agility to be able to release software faster, better, and deliver more value.”

    It has only been six short months since SoylentNews' Folding@Home team was founded, and we've made a major milestone: our team is now one of the top 500 teams in the world! We've already surpassed some heavy hitters like /. and several universities, including MIT. (But now is not the time to rest on our laurels. A certain Redmond-based software producer currently occupies #442.) In case you aren't familiar with folding@home, it's a distributed computing project that simulates protein folding in an attempt to better understand diseases such as Alzheimer's and Huntington's and thereby help to find a cure. To that end, SoylentNews' team has completed nearly 16,000 work units.
