False cacheline sharing: New tool to pinpoint where it's happening – DevNation talk

Is your application’s performance having problems scaling properly?  If so, do you know if it’s due to false cacheline sharing – causing the ping-ponging of cachelines between NUMA nodes?

False sharing occurs when one or more processes or threads repeatedly modifies data co-located in the same cacheline.  This forces the other processes and threads to invalidate their cached copies and reload, often from main memory, with the updated values.  This can slow programs down considerably.

DevNation Forecast – Cloudy with a Chance of Software Collections

I just can’t wait for DevNation, can you? I mean, conferences that bring together such a great amount of great people talking about great projects are just great!

I think we all know the two big topics of present: clouds and containerization. But the DevNation schedule shows that much more is going on. Personally, I can’t wait to see “Eleven Ceylon Idioms” by Gavin King. I’ve kept my eye on Ceylon language from its beginning and I think it really has the potential to become a “big language”.

DevNation talks I want to see, by Matt Newsome

We’ve just over a month to go until Red Hat Summit 2014 and the newly rebranded DevNation conference open their doors in San Francisco’s Moscone Center South, located in the heart of downtown San Francisco.

While we’re putting the finishing touches to our great new product releases for developers, we’re also really looking forward to attending the conferences ourselves. They present a great opportunity for like-minded developers to come together, see what’s new and share ideas – all part of the “Open Source way” Red Hat embodies.

Top Red Hat Developer News of 2013

Red Hat brought a LOT of new and excellent application development products and capabilities during 2013, so I thought I would assemble this list for you here in case you missed any.  Note that this is not a complete list (and comment if I missed something that you feel should be mentioned), and by the way, it is listed in random order.

Red Hat Software Collections general availability.  Yes, I will list this first as it’s my personal favorite as I started working on this two years prior as part of a project initially called Robbin, a moniker cleverly coined by Brian Gollaher, our RHEL developer tools product manager.  (We learned that people would be distracted if we gave it a name too soon in the planning phase – so they needed to agree on the definition first.  Then we could name it.  Our temporary offices were on Robbins Road then.)  At the time, we all understood the gap that we were trying to address, but it took some time to define it for enterprise use cases and then get some engineering resources (thank you, Denise Dumas).  So now here we are and we’re getting great feedback.  I can’t wait to share news on the next release!  😉
