A New York Times article questioning the business model for open source. MySQL, RedHat, SpringSource are some of the company names mentioned in the article.
There’s only one company making real money out of open source, and that’s Red Hat
— Simon Crosby, CTO Citrix Systems
Makes you think twice in case you were planning to go with the open source business model.
While I’m pretty sure there’s no need to create a new HTML parser, HTML is still a challenge
SGML (1986) didn’t fit into the kind of grammars or automata I had been taught at university.
The article shows some awesome write performance on Redis:
The benchmarks I’ve done were for applications which is very update intensive with updates being pretty much random single row updates which are hard to batch. With MySQL/Innodb I got server being able to handle some 30.000 updates/sec on 16 core server with replication being able to handle 10.000 updates/sec. This was using about 5 cores so you could probably get 4 MySQL instances on this server and get up to 100K updates/sec with up to 40K updates/sec being able to replicate.
With Redis I got about 3 times more updates/sec – close to 100.000 updates/sec with about 1.5 core being used. I have not tried running multiple instances and I’m not sure the network and TCP stack would scale linearly in this case but anyway we’re speaking about hundreds of thousands of updates/sec.
Even if Parallels is just a small contender on the desktop virtualization market, I think they are proposing a very Mac-like experience to Windows users:
It includes a universal serial bus (USB) cable that you connect between your older Windows computer and a new Mac. It automatically starts a utility that transfers all of the programs and important data from the old computer to the new one. It then allows you to run properly licensed Windows programs on the Mac.
