...If your concern is extremely long term deployments with verifiable data recovery options, software RAID is the only option, as you have strong guarantees that the implementation will never "die" as hardware RAID controllers are likely to do. As others have pointed out, there are indeed tangible benefits to using hardware RAID controllers. It all depends on your use case and project requirements.

Anyone made some performance comparison between XFS and ZFS with ZIL on SSD, in gluster environment ? I've tried to compare both on another SDS (LizardFS) and I haven't seen any tangible performance improvement. Is gluster different ?

...sembly is more of a special case than anything else. I don't really see why the right path forward is to design a generic framework around what was originally built for its specific purpose. If anything, I think the design you are pursuing is strictly more complex and invasive, and without any tangible benefits as a consequence. -Chandler -------------- next part -------------- An HTML attachment was scrubbed...

...eloquent emails, but you still haven't shown an exact use case - why not write a unit test which demonstrates the benefit and post a patch for review? for those who are not familiar with gtest/gmock it makes it very clear.. Then the discussion moves from opinions and "feelings" to tangibles

...ay 5304 controller with 128 meg dram The machine screams with this controller... yet I want to compare tests with it to the standard built in smart array controller etc Ive read bonnie++ stuff till I cant stand it no more and am just not seeing the relevance in the end result vectors to something tangible. Please advise and thanks in advance... - rh -- Robert - Abba Communications Computer & Internet Services (509) 624-7159 - www.abbacomm.net

...terested in predicting true vs false. I am interested in finding the most accurate probability predictions possible. I've seen some literature where the probability range is cut into segments and then the predicted probability is compared to the actual. This looks nice, but I need a more tangible numeric measure. One thought was a measure of "probability accuracy" for each range, but how to calculate this. Any thoughts? -N

...? What other projects are you carrying? Granted I'm a bit out of the loop these days but this is the first I'm hearing of this. Andrew has a well oiled machine going, so if he's still ok carrying the patches then that's where I'd like them until such time that you can provide a tangible benefit. Thanks, --Mark

...ould bring. To be clear it's not my favorite style, but it does have a very concrete advantage which is that we have a very large subproject already using it. it doesn't make sense to do a purely aesthetic move that not everyone is going to agree on anyway, when we could do one with actual tangible value.

To To me, it's not a matter of "one more dependency". If it makes sense and buys us something tangible, it would make sense to go with XML. In my mind, for our purposes, if the config file gets complex enough to need tool support like this, we have already failed. -Chris -- http://llvm.cs.uiuc.edu/ http://nondot.org/sabre/

...hurdles. At each step, I find another one. I''m sharing these development stories on the list for a few reasons: 1. Perhaps some of you will find the stories interesting 2. To preserve my lessons in the list archives so I, or someone else, can (re)learn from them later 3. As a record of tangible progress 4. To vent some frustration <grin> Yesterday, I spent a few hours debugging a weird problem in the calendar sample.

...tions for syncing programs with my Palm Pilot device. Google searches turn up a lot of discussion on the matter over a two or three year period, everything from people talking about doing it or how it should be done or how much they want it done. But I can't actually determine what, if any, tangible projects are out there for doing any kind of Palm syncing. The two programs I would most like to sync with my Palm are Thunderbird (just the addresses, not the email) and GnuCash (via FreeCoins?). It would seem I'm not the only one who would like to do this, and there are tantalizing hint...

...and modified the code to LLVM coding specifications. I was interested in taking up the project ideas on adding profile driven optimization passes and improving alias analysis as this would give me a chance to carry forward and improve my current work and also contribute significantly in terms of tangibles. I feel that my exposure to these areas during my thesis shall be an added advantage helping me to acclimatize with the project early enough. I have strong C/C++ skills acquired by working on several projects including my thesis. Besides my thesis I have previously taken classes on Compilers, com...

Hi :) My employer is looking to move a call centre to a new office, and has been increasingly frustrated with their legacy PBX (call-logging licensing and hardware upgrade costs). So I've stepped forth as the Open Source Pedant and suggested Asterisk so we can do all our own CallerID / call logging / analyses, and make use of IP Phones / teleworking, etc. The problem begins in that I only

Probably not. If there is, it would probably favor XFS. The developers at Red Hat use XFS almost exclusively. We at Facebook have a mix, but XFS is (I think) the most common. Whatever the developers use tends to become "the way l...

I think that 32-bit systems (especially ARM) may be short on memory so doubling the size of the table containing (potentially) all the functions may give a tangible overhead. I would even align the entries to 4 bytes (so 12 bytes per entry) on 32-bit platforms and to 8 bytes (so 24-bytes per entry) on 64-bit platforms, to improve CPU cache hits. What do you think?
