Ext3 and 3ware RAID5
I run a decent amount of 3ware hardware, all under centos-4. There seems to be some sort of fundamental disagreement between ext3 and 3ware's hardware RAID5 mode that trashes write performance. As a representative example, one current setup is 2 9550SX-12 boards in hardware RAID5 mode (256KB stripe size) with a software RAID0 stripe on top (also 256KB chunks). bonnie++ results look

Contrast
Could anyone please explain how to set up contrasts between means in R. I want to know if "before I conduct an experiment and believe the mean for 1 and 2 will be different from means 3 and 4, Is this true?" That is what I have to prove or disprove, I thought that contrasts would be the way to go. Thanks for the help. Igor [[alternative HTML version deleted]]

How to obtain seed after generating random number?
Dear all, I was doing an experiment to disprove some theory therefore performing lot of random simulation. Goal is to show the audience that although something has very rare chance to occur but it doesn't mean that event would be impossible. In this case after getting that rare event I need to show that same scenario for multiple times to explain other audience. Hence I need to somehow

[LLVMdev] SIV tests in LoopDependence Analysis, Sanjoy's patch
Hi Sanjoy, Reading through LoopDependenceAnalysis::analyseStrongSIV(), I noticed one problem and one confusion. My confusion related to your naming of the two instructions as A and B. It's consistent all through LoopDependenceAnalysis. I'd prefer something like source and destination, so I can keep track of which is which. It didn't matter so much when you were simply proving or

[LLVMdev] Array Dependence Analysis
Wojtek, If you like, I can help guide this SoC project. I would also like to see if we can coordinate with Alex and Albert, who are doing the class project here. As a first comment, your 3 layers are a good organization but two comments: 1. Layer 1 shd also look at loop bounds and array bounds: those can be used to disprove some deps. 2. The interface will also need to compute direction and

Unable to successfully join Samba 4.8.0 or Windows 2008 R2 to a Samba 4.6.7 DC, unable to upgrade in-place

GFS
Hello: I am planning to implement GFS for my university as a summer project. I have 10 servers each with SAN disks attached. I will be reading and writing many files for professor's research projects. Each file can be anywhere from 1k to 120GB (fluid dynamic research images). The 10 servers will be using NIC bonding (1GB/network). So, would GFS be ideal for this? I have been reading a lot

Windows 2003, Cygwin, and rsync
...up with a crossover cable between them for a straight, dedicated 1Gb/s But it certainly looks like rsync is not using more than a fraction of the (theoretically) available 100Mb/s There are several other hosts attached to the NetGear switch, and there is no "slowness" about them (which disproved my initial hypothesis of a saturated backplane) Is this a known rsync and/or Cygwin issue? I also get a "cannot send long-named file" message that halted rsync The file in question is probably a fluke, but this could happen again. How could I get rsync to just ignore the too-long filena...

An update on the DominatorTree and incremental dominators
Hi folks, For the past month I’ve been working on improving the DominatorTree and PostDominatorTree in LLVM. The RFC that explains the motivations and plans can be found here: http://lists.llvm.org/pipermail/llvm-dev/2017-June/114045.html . Here’s a short summary of what changed upstream since posting it: - We switched from the Simple Lengauer-Tarjan algorithm for computing dominators

stupid ZFS question - floating point operations
I have a coworker, who''s primary expertise is in another flavor of Unix. This coworker lists floating point operations as one of ZFS detriments. I''s not really sure what he means specifically, or where he got this reference from. In an effort to refute what I believe is an error or misunderstanding on his part, I have spent time on Yahoo, Google, the ZFS section of

2.2.2 runaway SMBD process
...becomes unkillable. The only resolution is to reboot the server completely. This has occurred at least once when a workstation crashed but we have not proven that this is always the case. I was rather hoping that it was a Windoze problem to do with not having SP2 installed but this has now been disproved. This is a serious problem. I have seen postings here before about disabling OPLOCKS but am reticent to do this becasue of the drop in performance which could put cracks in our arguments for using Samba in the first place. Also I thought 2.2.2 had fixes for OPLOCK bugs! Does anyone have any sug...

PBKDF2 password hashing as in ASP.NET Core
...SHA-256. So I'm out of luck here. The different formats are no longer relevant then. CRYPT-SHA512 is not anywhere near as secure as PBKDF2. But I've read and learned a lot about secure password hashing in the past 24 hours. My initial point that PBKDF2 is the state of the art has been disproved already. This order seems to be the case [1]: MD5/SHA1 << SHA2 << PBKDF2 < bcrypt < scrypt < Argon2 So I've changed my plans and try to go for Argon2 now. I found support for .NET Core [2] and Python [3]. My original question is kind of obsolete now because I also found...

killing undef and spreading poison
1. ————— Dan, The reasoning given below for how GVN operates seems odd to me, Poison is an attribute of a value, just like nsw is an attribute of an operation, So when GVN sees a pair of equal values, one of which has an extra attribute, The proper choice for representative value is the one without the attribute, Just like when GVN sees a pair of add operations, one of which has an

Memory usage issues
Hello all, I''m new to Mongrel and am very impressed with what I see so far. This thing beats FastCGI hands down, and is even simpler to use than SCGI. Great job Zed! Thanks for all the hard work. I am a bit surprised at the memory usage patterns though. I''m not sure if I''m doing something wrong (most likely I am), or if this is a problem with the app I''m

killing undef and spreading poison
Daniel, Thanks for taking the time to respond. Regarding GVN and newGVN, I recently finished a search through the llvm-dev archives for “nsw” in the subject line, and GVN was discussed in some of those threads [1]. In particular it was claimed that there was a right choice for GVN to make given two ADD instructions, one with the “nsw” attribute and one without, the one without ‘nsw’
