OpenSuse 10.2 Review

SUSE

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
OSS

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
HowTos

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

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
Software

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
Gaming

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
HowTos

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
skx@mine:~$

With that in mind the solution becomes:

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

Filed under
HowTos

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
Hardware

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
Reviews

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
OSS

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
Linux

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.

Linux Mint: Taking Ubuntu to the Next Level

Ubuntu

For the last several years, Ubuntu has been providing a superb desktop operating system consisting of open-source software. It has done a great job, but the philosophy behind Ubuntu prevents proprietary software from being included out of the box. This is where Linux Mint comes in.

Home networking Linux and Windows

Filed under
Linux

Lately I've been working on enabling network shares on most of the systems that run in my house. They're the various computers that have shown up over the years and are now parked in corners of rooms around my house. With the exception of the iMac and europa, every one came with Windows pre-installed. If they run Linux, it was installed well after the fact.

Open Source: Tell Me Why I Care

Filed under
OSS

My first planel for South by Southwest was titled, "Open Source: Tell Me Why I Care." Four advocates discussed the reasons for using open source. Pleasantly, there was almost no Microsoft-bashing, and only a little discussion of using open source because it's socially the right thing to do.

  • Kontena Launches Container Platform, Banks Seed Funding
    Startup Kontena has launched a container and microservices platform that, it claims, is designed to be developer friendly, easy to install and able to run at any scale -- attributes that, Kontena says, differentiate it from the current crop of container platforms. The Menlo Park, Calif.-based company, founded in March 2015, has also raised $2 million seed funding from Helsinki-based Lifeline Ventures. It also has a clever name: Say it out loud -- cute, huh? According to the team at Kontena Inc. , the startup's container and microservices platform requires zero maintenance, is designed for automatic updates, and runs on any infrastructure, including on-premises, cloud and hybrid. Combined, those attributes make it an easy-to-use alternative to platforms such as Docker, Kubernetes, Heroku and Mesosphere, the company says.
  • Stabilizing the world of hot and fast containers
    Containers are moving targets in multiple ways. With multiple tools, frameworks, implementations, and use cases to accomplish any task, it can be a fast-moving chaotic container world, which is a natural consequence of being young and popular. The good news is that all of this creative incubation is hugely productive, and because it's all open source everyone gets to share the benefits of all of this fabulous creativity. The bad news is that it's a giant energized cat herd. How do we know what direction to take? Must we plan for the work we do today to be obsolete in a few months? And, what about portability? I'd like to provide a few insights into the future of containers, and the direction we can expect the state of the art technology to take.
  • How DIGIT Created High Availability on the Public Cloud to Keep Its Games Running
    Emmanuel & Ross: HA is achievable on the public cloud. In our case, we couple redundancy across Availability Zone (AZ) with monitoring and autonomous systems to ensure our games can keep running. Using only one AZ will not ensure HA, as that entire zone could fail for a short time. Each of our applications runs in multiple containers at the same time. They're are all being monitored to handle current load. When one container is down, another takes its place. The same applies for all parts of our infrastructure. All services are autoscaling and behind a service discovery system. On top of this, nodes in our cluster are deployed across multiple AZs, each of which being an isolated network with its own NAT gateway. This way we can survive a whole zone going down.

  • LinuxCon: How Facebook Monitors Hundreds of Thousands of Servers with Netconsole
    The original kernel documentation for the feature explains that the netconsole module logs kernel printk messages over UDP, allowing debugging of problems where disk logging fails and serial consoles are impractical. Many organizations will choose to use syslog as a way to track potential server errors, but Owens said kernel bugs can crash a machine, so it doesn't help nearly as much as netconsole. He added that Facebook had a system in the past for monitoring that used syslog-ng, but it was less than 60 percent reliable. In contrast, Owens stated netconsole is highly scalable and can handle enormous log volume with greater than 99.99 percent reliability. "Netconsole is fanatically easy to deploy," Owens said. "Configuration is independent of the hardware and by definition you already have a network."

Android 7.0 Nougat

  • Android 7.0 Nougat review—Do more on your gigantic smartphone
    After a lengthy Developer Preview program starting in March, the final version of Android 7.0 (codenamed "Nougat") is finally launching today. The OS update will slowly begin to rollout to devices over the next few weeks. This year, Google is adding even more form factors to the world's most popular operating system. After tackling watches, phones, tablets, TVs, and cars, Nougat brings platform improvements aimed at virtual reality headsets and—with some help from Chrome OS—also targets laptops and desktops.
  • Google Android 7.0 Nougat Review – Surprisingly Uninspiring
    Since the past couple of years, Android updates have hit a concrete wall. Feature additions have gotten pretty mundane while focus on under the hood changes have become key for Google. Obviously, that’s a good thing, for some folks out there, but it’s a approach that doesn’t stand the test of time really very well. Users get frustrated after seeing the same thing over and over again. Same is absolutely true when you compare Android 7.0 Nougat directly with its predecessor, Android 6.0 Marshmallow.
  • Android 7.0 Nougat review: longer battery life and faster operation
    Android 7.0 Nougat is the new version of Google’s mobile operating system, used by billions of devices around the world. It features longer battery life, improved multitasking and smarter notifications in a slimmed down and refined Android experience – following on the work done in last year’s version 6 Marshmallow It is faster, more polished and a subtly-better experience all-round. Apps install more quickly, the OS can be smaller in size and updates to Android can be installed on the fly, without having to wait for 10 minutes while it reboots, if you have a new device. The new Vulcan API graphics system is also baked in for better gaming performance and Nougat will support Google’s Daydream virtual reality system, eventually. Nougat is not, however, a major visual overhaul of Android. Those that have used Marshmallow on any of Google’s Nexus smartphones or devices with little in the way of modification to Android, such as the OnePlus 3, will instantly recognise it.

    How do you measure the health of your community, identify problems, and track progress towards your goals? What should you be measuring? Last month we discussed vanity metrics, those metrics that might sound impressive on the surface, but ultimately give you little insight or guidance to improve the health and well-being of your community. This naturally begs the question: What should you be measuring? And as I mentioned last month, the obvious but annoying answer: It depends. The first and foremost dependency relates to the nature of your community and where you and your members want it to go.

  • Walmart, Comcast Hasten Innovation, Improve Agility With OpenStack
    As new technologies like applications and programming languages are introduced, it's important for companies to remain flexible and fast enough to adapt, which is why Walmart and Comcast have embraced OpenStack. By adopting OpenStack solution OneOps, Walmart doesn't have to spend unnecessary time writing code or automating new processes in order to keep up with new technologies, Andrew Mitry, OpenStack Lead at Walmart, explained today at OpenStack East 2016. Walmart already uses more than 3,000 applications and services and has more than 170,000 cores in more than 30 regions, with more than 60 Open Source products that are deployed more than 40,000 times each month. With OneOps, Walmart can automate low-level processes like load balance and firewalls using OneOps, which Mitry said frees up time and resources to manage more intricate processes that require manual oversight.
  • MySQL daddy Widenius: Open-source religion won't feed MariaDB
    MySQL daddy Monty Widenius has dismissed claims the MariaDB fork is veering away from open source. Rather, the chief technology officer of MariaDB corporation called his firm’s embrace of a commercial licence for part of MariaDB "critical" to delivering new revenue and for the continued development of open-source software. Widenius told The Register in an interview that he believes criticism of MariaDB’s commercial licence for its new database proxy sever, MaxScale 2.0, is motivated by a "religious" belief in free and open source software. Not that Widenius is against the belief per se, he told The Register, it’s just: "Religion doesn't put meat on the table."

FOSS in Government

  • Uganda eager to tap into open source
    Uganda's Ministry of ICT recently developed a FOSS (Free and Open Source Software) policy to regulate the deployment of open source software and use of open standards to accelerate innovation and develop local content. At the 7th African Conference on Free and Open Source Software (FOSS), organised in conjunction with Uganda's National Information Technology Authority (NITA-U) to encourage industry partnerships and uptake of OSS in East Africa, open software was recognised for its contribution to innovation. Frank Tumwebaze, Minister of ICT and National Guidance in Uganda, said, "Free and open software services will help my ministry to innovate better because it forms the platform (for) many of the innovative ideas. Free and open source software in Uganda is certainly something we have been talking about and I am sure we will do so even more in the next few days. Some of the things Uganda has put in place to harness the benefit from free and open source software include a Software Strategy and Policy in accordance with the United Nations Conference on Trade and Development's (UNCTAD) Trade, Services and Development expert meeting's determination that free and open source software is an inseparable component of the global technology ecosystem."

    Ireland was hit hard by the global financial crunch of 2007 and 2008. It was the first of the EU member states to slip into recession immediately following the bursting of the economic bubble. As the economy contracted, banks faced default and government debt increased, with Ireland eventually taking an €67.5bn loan from the European Commission, European Central Bank (ECB) and the International Monetary Fund (IMF) Falling tax income and the need to bail out banks saw the Irish government spending in other areas of public life. The government had introduced the Public Sector Recruitment Embargo in 2009, which stopped hiring of all civil servants across government and cut pay and pensions – in return for a promise of no compulsory redundancies.

In schools, that meant extending the life of IT, elimination of malware and re-re-reboots, freedom from paper, freight for paper, storage for paper, … For governments freedom from lock-in to M$ and “friends” saved huge sums which could have been better spent on hardware or employees.
