How do I... Configure TightVNC for remote access?

Filed under

Numerous remote administration and connectivity tools exist to help support technicians and IT administrators troubleshoot, maintain, and access systems in different locations. Some are easy to use and require no firewall configuration. Others possess expensive and potentially prohibitive licensing requirements, while delivering more advanced functionality.

How to create a command-line password locker

Filed under

Like many people, I have too many passwords to remember. To keep them straight, I wrote a simple password locker script using dialog and GnuPG (GNU Privacy Guard). The script prompts the user for a master password using a dialog box, unencrypts a file that holds a list of passwords, and opens the file in a text editor. When the editor is closed, the script re-encrypts the password file.

Howto install & use Flash, Java, Real Player 32 bit plugins under 64 bit Firefox

Gnome GDM Tricks

Filed under

It is possible to launch GDM, Gnome's Desktop Manager, automatically at startup so that you don't have to type startx all the time. Assuming you already have Gnome installed on your system, you just have to open as root /etc/inittab, and add the following line at the end of the file:

In Search Of GPL Version 3: The Long Road To Nowhere

Filed under

A month ago, I started down a path that I hoped would lead me to a great prize: an explanation from the authors of how the General Public License Version 3.0 was shaping up. Little did I know that this journey would contain more curves than San Francisco's Lombard Street.

Free Software Versus Open Source Software

Filed under

The terms "Free Software" and "Open Source Software" are often used interchangeably, and even abbreviated together as F/OSS (for "Free/Open Source Software"). Are there any differences between the two? If so, what are those differences? If not, why do the two different names exist? David Chisnall examines this paradox.

The Birth of Free Software

Using RADIUS to authenticate users with RSA SecurID

Filed under

Recently I was tasked with authenticating users who carry RSA SecurID tokens. I was highly inspired by Jeff Wirth and his success using RADIUS to authenticate with SecurID Tokens on FreeBSD. While I'm not a fan of non-free software, it's possible to make each server authenticate against the non-free RSA Ace server using only free software.

The Visual History of Ubuntu

Filed under

While Debian has been around for over a decade, Gentoo for five years, and Mandriva/Mandrake for nearly nine years, in less than three years of existence Ubuntu has received the most attention and generated the greatest amount of publicity in the Linux limelight. Why is that?

I received an interesting email the other day that I wanted to share with you:

Hi, Matt
Here’s another tip-of-the-cap for Linux Mint, as compared to my Ubuntu distro.

Science stars trace a long handwritten journey

Filed under

Alan Pierce stands next to a computer in a darkened classroom and traces "h-e-l-l-o" on a small computer's touch-sensitive data entry screen.

Instantly, "hello" appears in typewritten text, projected on a 5-by-8-foot wall screen behind him, below the likeness of his handwritten greeting.

Canonical Ltd Launches Global Partner Programme for Ubuntu

Filed under

Canonical Ltd, the commercial sponsor of Ubuntu, today announced its newly created Partner Programme to drive awareness and adoption of business-ready, Open Source server platforms, and desktop solutions.

Backing Up with Keep

Filed under

Keep is the second entry in my Backing Up series. It is a lightweight app that makes it simple to create and manage multiple backups. At first glance Keep's feature set looks very solid, but when trying it out I quickly discovered some limitations that really limit its potential.

I tested with version 0.3.0 and 0.4.0 on Kubuntu Edgy and 0.4.0 on Debian Etch.

Appearance and Useability

Will Microsoft buy Novell?

Filed under

The answer to that question is probably not, though the thought had crossed my mind. In a way they already have done in a small way, they have given Novell approximately a quater's worth of net profit in return for what appears to be a cut of all Open Enterprise and SUSE Linux sales. Although no shares have changed hands, this, in itself, seems to me to be a kind of "virtual" company sale.

Nominations open for second annual Mellon Foundation technology awards

Filed under

The Andrew W. Mellon Foundation's Research in Information Technology (RIT) program has opened nominations for the 2007 Mellon Awards for Technology Collaboration (MATC). Prizes of $50,000 to $100,000 will be awarded to the winners in December.

Taiwan notebook players sound off on Linux

Filed under

Considering that Dell recently asked its clients for their opinions on selling Linux-based notebooks, it was interesting to raise the same question to Taiwan-based notebook, and the results showed that branded players are more conservative than ODM manufacturers concerning adopting Linux compared with a Microsoft operating system (OS).

Open Source is enjoying a fabulous ride, with F1000 adoption growing, developers and architects seeking training and new projects incubating and maturing all the time.

Recovering data from a damaged partition

Filed under

Most of the time GNU/Linux is a powerful Operating System. Sometimes, i wish i had think thought before using one of its great console command, the simple and rapid dd.

In order to make room on one hard drive, i used dd to sweep the first 512 bytes of the boot sector, in order to let the other operating system to boot by itself instead of using lilo.

  • GNOME Core Apps Hackfest
    The hackfest is aimed to raise the standard of the overall core experience in GNOME, this includes the core apps like Documents, Files, Music, Photos and Videos, etc. In particular, we want to identify missing features and sore points that needs to be addressed and the interaction between apps and the desktop. Making the core apps push beyond the limits of the framework and making them excellent will not only be helpful for the GNOME desktop experience, but also for 3rd party apps, where we will implement what they are missing and also serve as an example of what an app could be.

  • 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.
