20 years of Qt

By corbet Lars Knoll marks the
20th anniversary of the Qt toolkit
on the Qt blog. “From the
beginning, Qt has been released with both open source and commercial
licensing options. Over the years, we have worked on expanding this model,
and nowadays, Qt is actually developed as an open source project. In this
sense Qt is actually in a rather unique position, having a strong ecosystem
with passionate people, as well as a commercial entity behind it, which
backs up and funds most of the development.

How to Make Money from Open Source Platforms (Linux.com)

By ris Over at Linux.com, John Mark Walker examines
why companies aren’t making money on pure open source ventures. “It is not that there is no money in selling open source software, but rather that the business models have shifted. Whereas, under the old proprietary world, a larger percentage of money went to pure software vendors, now that money has spread among a larger spectrum of companies and industries; lots of people get paid to work on or with open source software, but an increasing number of them don’t work for software vendors, per se. In addition to looking in all the wrong places, the current investment model is suspicious of an open source approach. The vast majority of venture capitalists, especially in Silicon Valley, are very risk averse and shy away from open source products that, in their view, will not give as large a return on their investment. In order to secure the funding required to scale a company, investors will frequently require that the startup company include proprietary bits as tools to increase revenue and margins. These two factors – diffusion of revenue and risk-averse investors – combine to both give a false impression and, in part due to the false impression, prevent pure open source software vendors from getting funding.

Kernel prepatch 4.1-rc4

By corbet Linus has released the 4.1-rc4 kernel
prepatch, saying: “So here it is, last-minute fix and all. The -rc4
patch is a bit bigger than the previous ones, but that seems to be mainly
due to normal random timing – just the fluctuation of when submaintainer
trees get pushed.
