New Year’s resolution: Donate to 1 free software project every month

Free and open source software is an absolutely critical part of our world—and the future of technology and computing. One problem that consistently plagues many free software projects, though, is the challenge of funding ongoing development (and support and documentation). With that in mind, I have finally settled on a New Year’s resolution for 2017: to donate to one free software project (or group) every month—or the whole year. After all, these projects are saving me a boatload of money because I don’t need to buy expensive, proprietary packages to accomplish the same things.+ Also on Network World: Free Software Foundation shakes up its list of priority projects + I’m not setting some crazy goal here—not requiring that I donate beyond my means. Heck, some months I may be able to donate only a few bucks. But every little bit helps, right? To read this article in full or to leave a comment, please click here

Top 25 worst-of-the-worst, most common passwords used in 2016

For the sixth year in a year, SplashData has released its list of worst passwords.According to SplashData, the list is based on over five million leaked passwords, which are used by users in North America and Western Europe, that were posted for sale online.I thought it might be interesting to compare SplashData’s newest list with the top 25 most common password list released last week by rival firm Keeper Security. According to the two companies, these were the top 25 worst passwords people used in 2016:To read this article in full or to leave a comment, please click here

Telegraf, InfluxDB, Chronograf, and Kapacitor

The InfluxData TICK (Telegraf, InfluxDB, Chronograf, Kapacitor) provides a full set of integrated metrics tools, including an agent to export metrics (Telegraf), a time series database to collect and store the metrics (InfluxDB), a dashboard to display metrics (Chronograf), and a data processing engine (Kapacitor). Each of the tools is open sourced and can be used together or separately.
This article will show how industry standard sFlow agents embedded within the data center infrastructure can provide Telegraf metrics to InfluxDB. The solution uses sFlow-RT as a proxy to convert sFlow metrics into their Telegraf equivalent form so that they are immediately visible through the default Chronograf dashboards (Using a proxy to feed metrics into Ganglia described a similar approach for sending metrics to Ganglia).

The following telegraf.js script instructs sFlow-RT to periodically export host metrics to InfluxDB:
var influxdb = "http://10.0.0.56:8086/write?db=telegraf";

function sendToInfluxDB(msg) {
  if(!msg || !msg.length) return;
  
  var req = {
    url:influxdb,
    operation:'POST',
    headers:{"Content-Type":"text/plain"},
    body:msg.join('\n')
  };
  req.error = function(e) {
    logWarning('InfluxDB POST failed, error=' + e);
  }
  try { httpAsync(req); }
  catch(e) {
    logWarning('bad request ' + req.url + ' ' + e);
  }
}

IDG Contributor Network: Public vs. private cloud: Why the public cloud is a real threat to security

The debate on public versus private cloud is a fierce one with advocates on both sides. Security experts, however, consistently fall in the pro-private camp. As a compliance and security expert, I have to agree.First, let’s be clear on the definitions.The public cloud is available to the public—in a free or pay-per-use capacity—and is accessible via the web. Some examples include Google Apps, Office 365, file sharing applications such as Box or Dropbox, and so on. The private cloud, on the other hand, is the same service, but it sits behind your firewall and limits access to your internal departments, employees, customers, etc. in your organization. The private cloud is either run by your IT department or your data center. To read this article in full or to leave a comment, please click here

Worth Reading: Constructing your CCDE Practical Exam Strategy

This blog is the second of a two-part series focused on preparing candidates for success in achieving the CCDE. Mastering the tools available to you can be a “force multiplier” on exam day. There are three primary tools available to you during the practical exam: on-screen highlighting, built-in notepad, and a physical dry-erase board. I will discuss each of these in detail. All candidates have access to each tool for all four scenarios. —Cisco Learning Network

Avaya, in no-brainer, pulls $1 billion IPO in wake of bankruptcy filing

Avaya Holdings has withdrawn the $1 billion IPO offering it filed more than 5 years ago in the wake of last week's filing for Chapter 11 bankruptcy by principal U.S. subsidiary Avaya, Inc. Avaya was taken private in 2007 after being acquired by two private equity firms for $8.2 billion. Enterprise networking and collaboration vendor Avaya said last week that its Chapter 11 filing is part of its transition from a hardware to software and services company. The company, which is looking to shed its $6 billion debt load, last week reported decreased revenue and an operating loss for its fiscal year ended Sept. 30.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Data center managers, it’s time to commit to those New Year’s resolutions

Whether it’s a new exercise program, volunteering for charitable causes or deciding to go gluten-free, studies have shown that nearly half of people who fully commit to New Year’s resolutions were over 10 times more likely to succeed at realizing real change as compared to 4 percent who do not.The concept of New Year’s resolutions dates back to the Babylonians, who at the start of each year made promises to their gods to return borrowed objects and pay their debts. Romans, too, would begin each year by making promises to Janus, the god of beginnings and transitions, for whom the month of January is named.+ Also on Network World: More proof the cloud is winning big + But wait, dear data center manager. You say you don’t have time to do gut-crunchers every morning and balk at the prospect of giving up bread and pasta? To be perfectly clear, I understand but do not condone your lack of commitment. Change is difficult. And besides, some who follow cultural trends claim that dad bods are slowly coming into fashion.To read this article in full or to leave a comment, please click here

Many Organizations Still Opt for “Good Enough” Cybersecurity

Late last year, ESG published a research report titled, Through the Eyes of Cyber Security Professionals, in collaboration with the Information Systems Security Association (ISSA).  As part of this report, 437 cybersecurity professionals and ISSA members were asked if they’d experienced a number of types of security incidents.  The research revealed that: 39% of organizations experienced one or several security incidents resulting in the need to reimage one or several endpoints or servers. 27% of organizations experienced one or several incidents of ransomware. 20% of organizations experienced one or several incidents resulting in the disruption of a business application. 19% of organizations experienced one or several incidents resulting in the disruption of a business process. It should be noted that between 23% and 30% of the survey population responded “don’t know” or “prefer not to say” when asked about different types of security incidents so the percentages represented above are likely much higher.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Tricentis scoops up mega cash to help enterprises test software

Software testing has always been “a thing.” It has always been necessary to test the various aspects of the software solutions that enterprises create before putting them out in the wild.But the thing that has changed is that software is now incredibly more pervasive than it has ever been before. There are orders of magnitude more software solutions than at any time in the past. Add to that the fact that the complexity of software is always increasing, and you have a real challenge from the perspective of testing.So, it should come as no surprise to see an increasing number of tools and solutions that aim to solve the testing issue—from crowd-sourcing platforms that allow the “wisdom of the masses” to help worth an organization’s testing process to platforms that offer to “automate” all or part of the testing process.To read this article in full or to leave a comment, please click here

6 EMM predictions for 2017
