Thinking about trying Linux?

Filed under

You have probably heard about this thing called Linux. Everybody seems to be arguing over it. Is it better than Windows or faster or cheaper. Some say it doesn't support anything while others say it supports more than windows. Your curiosity is aroused and you wonder if you should give linux a try before parting with a few hundred dollars for the latest version of windows.

Mark Shuttleworth: A very good start

Filed under

I’m very impressed with the results of the early work being done at the new Linux Foundation, which is OSDL+FSG with a leaner focus on getting things done.

MAYA 8.5

Filed under

This upgrade follows hot on the heels of Maya 8, and adds native compatibility with Intel Macs. However, it’s more than just a compatibility fix – the update adds a lot of new features, too, particularly in the field of simulations.

New advances are based around a unified simulation framework called Maya Nucleus. This is a linked particle system that allows simultaneous interactive simulations acting on a variety of dynamic objects. All of your simulations can affect each other and can be affected by the same forces and constraints, such as wind and gravity.

OpenSuse 10.2 Review

Filed under

I just got finished installing OpenSuSE 10.2 on my Linux workstation. It had been at 10.0. Overall, it is very painless. It's a lot easier than installing Windows.

Open Source and You

Filed under

No one would buy a car with the hood welded shut, but that is essentially what commercial software is. However, since computing began, some software has been distributed in such a way that users can change or repair it by modifying its source code--the step-by-step instructions that the computer executes when the software runs. Software distributed under a license that allows a programmer to modify the source code and freely distribute an improved version of it is called open source.

Crontab Configuration, OpenSUSE 10.2

Filed under

At some point several years ago, SUSE and Redhat migrated to new multi-file and sub-directory approaches (search anacron) for their system crontabs. A helpful comment posted to my 2 March entry motivated me to learn how these are set up. Here’s how openSUSE 10.2 structures its cron configuration and provides the means of controlling it:

* YaST, System, sysconfig editor, cron - edits various configuration parameters stored in the /etc/sysconfig/cron file (this file can also be edited directly).
* YaST, System, System Services - turn the cron service on/off here.

Join the KDE Event Coordination Task Force now!

Filed under

KDE is visiting a lot of events on a yearly basis. In most cases, the booth is staffed by volunteers. A successful event attendance depends on a number of factors, if those aren't considered, it might end in frustrated, or even burnt out contributors. But getting it right is not just about "went good / bad", there are various shades of grey. Having a look at past events, the most important factors seem to be in two groups, general considerations and planning and per-event planning.

Zabbix: State-of-the-art network monitoring

Filed under

I have used BigBrother and Nagios for a long time to troubleshoot network problems, and I was happy with them -- until Zabbix came along. Zabbix is an enterprise-class open source distributed monitoring solution for servers, network services, and network devices. It's easier to use and provides more functionality than Nagios or BigBrother.

Freeing an old game - Relicensing UMoria

Filed under

People are often attracted to games before they are attracted to the free software movement. This means that many free software enthusiasts are addicted to non-free games. This is what turns some people to free software—the inability to see how a game works, or the inability to legally share it with friends.

Writing shell scripts which execute locally or remotely

Filed under

There are a lot of times when it is useful to have a single shell script run both upon the local host, and also upon remote hosts. Here we'll show a simple trick which allows you to accomplish this easily.

To execute shell scripts remotely the most obvious approach is to copy it there, with scp, and then use ssh to actually execute it. This is similar to running simple commands remotely using ssh directly:

skx@mine:~$ ssh yours uptime
07:12:25 up 3 days, 18:15, 0 users, load average: 0.00, 0.00, 0.08

With that in mind the solution becomes:

Network File System (NFS) Server and Client Configuration in Debian

Filed under

NFS was developed at a time when we weren’t able to share our drives like we are able to today - in the Windows environment. It offers the ability to share the hard disk space of a big server with many smaller clients. Again, this is a client/server environment. While this seems like a standard service to offer, it was not always like this. In the past, clients and servers were unable to share their disk space.

Why Dell Is Really Saying No to Linux

By now, many of you may be wondering why Dell is passing up such a great niche market by not offering Linux as an alternative OS option to Windows. We have talked about how this would only prove to benefit a company like Dell, but we have also acknowledged the fact that it will likely never happen.

One laptop per child

Filed under

For some time, I've been aware of online discussions going on about an innovative project to build cheap laptop computers to be given to kids in developing countries.

The goal was to build a sub-$100 (about R740) laptop computer which could not only be used by children to learn computing skills, but to assist them with completing their other schoolwork as well.

I reserved judgement on the idea but it now seems as if it really is going to fly, with numbers of test machines having been delivered to communities around the world and large scale production due to start later in the year.

Book Review: IPCOP Firewalls - Closing borders with Open Source

Filed under

IPCop is a GPLed firewall solution targeted at Small Office/Home Office network. It is favored by many for its ease of configuration and setup and its support for a variety of features that you would expect to have in a modern firewall. IPCop is famed for letting users setup a sophisticated firewall for ones network without ever having to write an iptables rule themselves.

Are you an open source user or joiner?

Filed under

In my previous column, I touched on the issue of what constitutes an open-source vendor. Ask Andy Astor that question, and his answer is a shrug. "Honestly," he says, "who cares?" To Astor, there are really two broad categories of companies with respect to their relationship to open-source code. Some are users. Others are joiners.

An open letter: from a consumer to the distributions

Filed under

My name is Adam Posey, I'm a resident of Elkins, West Virginia and a GNU/Linux user. I do not run a server nor I do not own a business. What I do have is considerable influence over the buying decisions of other people around me because I am knowledgeable in technology. I have grown very weary of the current state of Linux for the home user.

A Second Look At Pardus 2007.1 RC: Surprises, Surprises

Filed under

My first look at Pardus 2007.1 Release Candidate was somehow pessimistic, however I was confident in the future. This second attempt will start by showing some success, however it will end with an even more pessimistic view. But let's not anticipate...

An Update On Server/Site Move

Filed under
Site News

Well, I guess we'll go with this debian install. I still haven't worked out all the kinks yet cuz my gran'babies came over today and I didn't get a chance to work on things. I took the opportunity to upgrade drupal as you may have noticed too, and it was a much easier upgrade this time.

  • Netflix on Firefox for Linux
    If you're a Firefox user and you're a little fed up with going to Google Chrome every time in order to watch Netflix on your Linux machine, the good news is since Firefox 49 landed, HTML5 DRM (through the Google Widevine CDM (Content Decryption Manager) plugin) is now supported. Services that use DRM for HTML5 media should now just work, such as Amazon Prime Video. Unfortunately, the Netflix crew haven't 'flicked a switch' yet behind the scenes for Firefox on Linux, meaning if you run Netflix in the Mozilla browser at the moment, you'll likely just come across the old Silverlight error page. But there is a workaround. For some reason, Netflix still expects Silverlight when it detects the user is running Firefox, despite the fact that the latest Firefox builds for Linux now support the HTML5 DRM plugin.

    Public policy makers in Sweden have limited insight on how IT project can lead to IT vendor lock-in, a study conducted for the Swedish Competition Authority shows. “An overwhelming majority of the IT projects conducted by schools and public sector organisations refer to specific software without considering lock-in and different possible negative consequences”, the authors conclude.
  • How open access content helps fuel growth in Indian-language Wikipedias
    Mobile Internet connectivity is growing rapidly in rural India, and because most Internet users are more comfortable in their native languages, websites producing content in Indian languages are going to drive this growth. In a country like India in which only a handful of journals are available in Indian languages, open access to research and educational resources is hugely important for populating content for the various Indian language Wikipedias.
  • Where to find the world's best programmers
    One source of data about programmers' skills is HackerRank, a company that poses programming challenges to a community of more than a million coders and also offers recruitment services to businesses. Using information about how successful coders from different countries are at solving problems across a wide range of domains (such as "algorithms" or "data structures" or specific languages such as C++ or Java), HackerRank's data suggests that, overall, the best developers come from China, followed closely by Russia. Alarmingly, and perhaps unexpectedly, the United States comes in at 28th place.

  • AtScale Delivers Findings on BI-Plus-Hadoop
    Business intelligence is the dominant use-case for IT organizations implementing Hadoop, according to a report from the folks at AtScale. The benchmark study also shows which tools in the Haddop ecosystem are best for particular types of BI queries. As we've reported before, tools that demystify and function as useful front-ends and connectors for the open source Hadoop project are much in demand. AtScale, billed as “the first company to allow business users to do business intelligence on Hadoop,” focused its study on the strengths and weaknesses of the industry’s most popular analytical engines for Hadoop – Impala, SparkSQL, Hive and Presto.
  • Study Says OpenStack at Scale Can Produce Surprising Savings
    Revenues from OpenStack-based businesses are poised to grow by 35 percent a year to more than $5 billion by 2020, according to analysts at 451 Research. In its latest Cloud Price Index, 451 Research analyzes the costs associated with using various cloud options to determine when it becomes better value to use a self-managed private cloud instead of public or managed cloud services. The idea is to createa complex pricing model that takes into consideration the major factors impacting total cost of ownership (TCO), including salaries and workload requirements.The 451 study found that because of the prevalence of suitably qualified administrators, commercial private cloud offerings such as VMware and Microsoft currently offer a lower TCO when labor efficiency is below 400 virtual machines managed per engineer. But where labor efficiency is greater than this, OpenStack becomes more financially attractive. In fact, past this tipping point, all private cloud options are cheaper than both public cloud and managed private cloud options.
  • How OpenStack mentoring breaks down cultural barriers
    Victoria Martinez de la Cruz is no stranger to OpenStack's mentorship opportunities. It's how she got her own start in OpenStack, and now a few years later is helping to coordinate many of these opportunities herself. She is speaking on a panel on mentoring and internships later this week at OpenStack Summit in Barcelona, Spain. In this interview, we catch up with Victoria to learn more about the details of what it's like to be a part of an open source internship, as well as some helpful advice for people on both sides of the mentoring process.
