Network Monitoring Appliance

My ambition was to implement a small (better tiny) appliance for monitoring network health and network resources, short and longtime trends, running under VMware Server or VMware ESX. So I had an eye upon all components which are implemented on the system, to be as leightweight as possible.

Leftovers: OSS and Sharing

  • Making your OpenStack monitoring stack highly available using Open Source tools
    Operators tasked with maintaining production environments are relying on monitoring stacks to provide insight to resource usage and a heads-up to threats of downtime. Perhaps the most critical function of a monitoring stack is providing alerts which trigger mitigation steps to ensure an environment stays up and running. Downtime of services can be business-critical, and often has extremely high cost ramifications. Operators working in cloud environments are especially reliant on monitoring stacks due to the increase in potential inefficiency and downtime that comes with greater resource usage. The constant visibility of resources and alerts that a monitoring stack provides, makes it a fundamental component of any cloud.
  • InfraRed: Deploying and Testing Openstack just made easier!
  • The journey of a new OpenStack service in RDO
    When new contributors join RDO, they ask for recommendations about how to add new services and help RDO users to adopt it. This post is not a official policy document nor a detailed description about how to carry out some activities, but provides some high level recommendations to newcomers based on what I have learned and observed in the last year working in RDO.
  • Getting to know the essential OpenStack components better

  • Testing LibreOffice 5.3 Notebookbar
    I teach an online CSCI class about usability. The course is "The Usability of Open Source Software" and provides a background on free software and open source software, and uses that as a basis to teach usability. The rest of the class is a pretty standard CSCI usability class. We explore a few interesting cases in open source software as part of our discussion. And using open source software makes it really easy for the students to pick a program to study for their usability test final project.
  • [Older] Drupal member sent out after BDSM lifestyle revealed

    Drupal, like many other open source projects, has a stated goal of welcoming and accepting all people, no matter their heritage, culture, sexual orientation, gender identity or other factors.

  • Controversy Erupts in Open-Source Community After Developer's Sex Life Made Public
    Drupal is a popular open-source content-management system, used to build websites. Like many other open-source projects, Drupal is guided by several committees that are supposed to be accountable to the community and its code of conduct, which enshrines values like "be considerate" and "be respectful." Also like many other open-source projects, Drupal attracts all sorts of people, some of whom are eclectic. Last week, under murky circumstances, Drupal creator Dries Buytaert banned one of the project's technical and community leaders, Larry Garfield. Buytaert attributed the decision to aspects of Garfield's private sex life. Many Drupal users and developers are up in arms about the perceived injustice of the move, exacerbated by what they see as a lack of transparency.
  • HospitalRun: Open Source Software for the Developing World
    When open source software is used for global health and global relief work, its benefits shine bright. The benefits of open source become very clear when human health and human lives are on the line.

  • Scotland emphasises sharing and reuse of ICT

  • Austria state secretary promotes open data
    The State Secretary at Austria’s Federal Chancellery, Muna Duzdar, is encouraging the making available of government data as open data. “The administration must set an example and support the open data culture by giving society its data back”, the State Secretary for Digitalisation said in a statement.
  • Study: Hungary should redouble open data initiatives

  • Williamson School Board OKs developing open source science curriculum

  • How Elsevier plans to sabotage Open Access
    It was a long and difficult road to get the major publishing houses to open up to open access, but in the end the Dutch universities got their much awaited ‘gold deal’ for open access. A recently revealed contract between Elsevier and the Dutch research institutes lays bare the retardant tactics the publishing giant employs to stifle the growth of open access.

Security Leftovers

  • Security updates for Monday
  • FedEx Will Pay You $5 to Install Flash on Your Machine
    FedEx is making you an offer you can’t afford to accept. It’s offering to give you $5 (actually, it’s a discount on orders over $30) if you’ll just install Adobe Flash on your machine. Nobody who knows anything about online security uses Flash anymore, except when it’s absolutely necessary. Why? Because Flash is the poster child for the “security-vulnerability-of-the-hour” club — a group that includes another Adobe product, Acrobat. How unsafe is Flash? Let’s put it this way: seven years ago, Steve Jobs announced that Flash was to be forever banned from Apple’s mobile products. One of the reasons he cited was a report from Symantec that “highlighted Flash for having one of the worst security records in 2009.” Flash security hasn’t gotten any better since.
  • Every once in a while someone suggests to me that curl and libcurl would do better if rewritten in a “safe language”
  • An insecure dishwasher has entered the IoT war against humanity

    Regel says that he has contacted Miele on a number of occasions about the issue, but had failed to get a response to his missives, and this has no updated information on the vulnerability.

    He added, bleakly that "we are not aware of an actual fix."

  • Monday Witness: It's Time to Reconize a Civil Right Not to be Connected
    Along with death and taxes, two things appear inevitable. The first is that Internet of Things devices will not only be built into everything we can imagine, but into everything we can't as well. The second is that IoT devices will have wholly inadequate security, if they have any security at all. Even with strong defenses, there is the likelihood that governmental agencies will gain covert access to IoT devices anyway. What this says to me is that we need a law that guarantees consumers the right to buy versions of products that are not wirelessly enabled at all.
  • Remember kids, if you're going to disclose, disclose responsibly!
    If you pay any attention to the security universe, you're aware that Tavis Ormandy is basically on fire right now with his security research. He found the Cloudflare data leak issue a few weeks back, and is currently going to town on LastPass. The LastPass crew seems to be dealing with this pretty well, I'm not seeing a lot of complaining, mostly just info and fixes which is the right way to do these things.

Lightroom and Darktable: the verdict two years after switching

In summer 2015, I posted a detailed account of my tentative switch from Windows7 and Lightroom to Linux and Darktable. This was sparked by sudden crashes that were afflicting my system, but in a deeper sense grew from frustration with Windows and, to a lesser degree, with Lightroom. Once I headed for Linux, I decided to plunge in fully and commit to using Ubuntu and free, open-source photo software for several months – at least until the end of that year. That would give me a chance to see whether I could actually run my photography business on the new system. Read more
