Code scanning and management vendor Black Duck reports the GNU General Public License v2 (GPLv2) now dipping below 50% share of open source software. While we already knew that GPLv2 was somewhat in decline from its far greater share of open source code over the last 5-10 years, it is useful to know what pool of code we’re talking about. We must also remember that while GPLv2 may not be as dominant as it once was and that other licenses, particularly GPLv3, are quickly gaining share, GPLv2 is still quite relevant to enterprise open source software, is used in a variety of newer and popular applications across the enterprise stack and is likely to remain in the top 10 licenses for a long time.

Regarding GPLv2 and Black Duck’s findings, some folks are rightly asking what code and how much of it are we considering where GPLv2 accounts for half or less of the …

We reported recently on Red Hat’s revenue growth and deferred revenue. One of the things I have been looking at recently is the slowdown in Red Hat’s growth in recent years, and the opportunities that the company has to improve that growth.

For some perspective it is worth noting that while Red Hat’s revenue has been growing steadily:

The rate of growth has been in decline for some time:

We have also noted (451 Group clients only) that the company will in …

Red Hat is celebrating the 10 year anniversary of its initial public offering. An anniversary to be proud of for Red Hat, but one that has given The VAR Guy pause for thought about the relative success of open source in the past 10 years.

“Would anyone have predicted that no additional open source companies would launch IPOs over the next decade? Ten years without an open source IPO … amazing and somewhat depressing for open source business advocates,” writes the VAR Guy.

It is somewhat depressing that there are not more public open source vendors. However, the statement that there have been …

As well as contributing to the CAOS research practice here at The 451 Group I am also part of the information management team, with a focus on databases, data caching, CEP, and - from the start of this year - data warehousing.

I’ve covered data warehousing before but taking a fresh look at this space in recent months it’s been fascinating to see the variety of technologies and strategies that vendors are applying to the data warehousing problem. It’s also been interesting to compare the role that open source has played in the data warehousing market, compared to the database market.

I’m preparing a major report on the data warehousing sector, for publication in the next couple of months. What follows is a rough outline of the role open source has played in the sector. Any comments or corrections much appreciated:
