Job Opening Trends

by Reginald Charney

Fuzzy Data

There was a plethora of terms found when analyzing the job-opening descriptions. For example, Windows' terms include 95, NT, CE, Win, Windows NT, etc. Besides various abbreviations, there are also ambiguous words. Is Win followed by NT to be counted as Windows and Windows NT or just Windows NT alone? Generally, the “maximum munch” rule is used. That is, the longest recognizable term possible is used. Then there are still the misspellings and unknown words. Thus, all this makes determining what is required fuzzy. Having said that, here are some of the statistics used in the job descriptions:

  • number of job openings: 129,000

  • number of unique words: 12,200

  • number of unique skill sets: 68,800

Five most often used words:

  • C++: 19,951

  • Java: 16,920

  • SQL: 9,121

  • vb: 9,003

  • HTML: 8,788

  • JavaScript: 4,793

As you would expect with all these terms, skill sets made up of a couple of words would tend to appear more often than skill sets made up of three or more words. The top five skill sets were:
  • frame relay: 445

  • Oracle dba: 445

  • C++ Java: 412

  • WinNT server: 361

  • Shell script: 361

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
