A customer has a zpool where their spectral analysis applications create a ton (millions?) of very small files that are typically 1858 bytes in length. They''re using ZFS because UFS consistently runs out of inodes. I''m assuming that ZFS aggregates these little files into recordsize (128K?) blobs for writes. This seems to go reasonably well amazingly enough. Reads are a

...LT_DLMUTEX_SETERROR (DLERROR (SYMBOL_NOT_FOUND)); } return address; } break the ability to detect an undefined symbol versus a symbol with a value of 0 because it sets the lt_dlerror() whenever dlsym() returns 0. Perhaps a bug in libtool, I was looking at 1.5.6, but it's a twisty maze and I could have taken a wrong turn. It's clear dlsym() gives the required functionality; the layers of wrapping on top of it present a broken interface. Cheers, Ralph.

It is a twisty mess. Function pointers in structures? Who'd ever do THAT? :) We're currently using 1.5.22 but it doesn't look any different than what you ahve above. I'm about to upgrade the support module to use 1.5.24 (latest stable...

Hi Xen folks! I''ve faced with one strange thing in ARM version of Xen: when I use xc_map_foreign_bulk() to map some memory from domU to dom0, after unmap() for previous returned address - memory is not freed at all. Let''s look at call stack: xc_map_foreign() -> linux_privcmd_map_foreign_bulk() -> { addr = mmap(fd); ioctl(fd, IOCTL_PRIVCMD_MMAPBATCH_V2 );

I would like to output the following information when running a spec (_also_ on success): - the description text - the expected value - the actual value After looking through the documentation I thought custom formatters might be the way to go, but unfortunately it does not look like all variables are accessible from there? I need this for an academic report where all testing needs to be

...r, I question several fundamental assumptions: 1) We should be very certain that -ffunction-sections is not a viable solution as it exists and is well supported in other toolchains and environments. 2) We should talk to other ELF producers and coordinate to make sure we don't end up creating a twisty maze of extensions here. 3) We should step back and consider leapfrogging to a fully specialized format to reap even more performance benefits rather than messily patching ELF. #3 may prove irrelevant if this is the only major hurdle for speeding up ELF links. My impression was otherwise. #2 ha...

I'm working on a small server written in Go to add short-lived user certificates to the forwarded agents of authorized users. https://github.com/rorycl/sshagentca This seems to work quite well for accessing sshd servers with the appropriately configured "TrustedUserCAKeys" directive. I have been in a debate about how similarly adding host certificates to forwarded agents could

...tor callback but that falls over if the skb is cloned since you also need to know when the clone is destroyed. Jeremy Fitzhardinge and I subsequently looked at the possibility of a no-clone skb flag (i.e. always forcing a copy instead of a clone) but IIRC honouring it universally turned into a very twisty maze with a number of nasty corner cases etc. It also seemed that the proportion of SKBs which get cloned at least once appeared as if it could be quite high which would presumably make the performance impact unacceptable when using the flag. Another issue with using the skb destructor is that func...

...occasional backwards-incompatible changes. 2) Don't burn our early adopters by breaking their working configurations without ample warning. 3) Avoid having to be stuck with maintaining backwards compatibility code in perpetuity. This is for both workload and security reasons; more twisty compat code == more bugs. So my working, self-imposed policy is to retain backwards compatibility support for at least 13 months after the release that includes an incompatible change. This duration is intended to let users sign certs of one year duration and know that an OpenSSH release won't...

...hen you say 'n' to *that* it asks you for Vhost driver for vDPA-based backend (VHOST_VDPA). This kind of crazy needs to stop.

I have a dataset of the form Year tosk.fai tosk.isd tosk.gr ....... tosk.total hysa.fai hysa.isd ... and so on. I want to sum all the columns using the first four letters in the columns label(e.g. 'tosk', 'hysa' etc.). How can you do that? Also, the sums should be without the '.total'column (e.g. 'tosk.total') as this serves as a check that

Hi there, I am working on a project which needs the value of the interaction area under two distributions( eatimated by kernel density estimators). For example: x<-rnorm(100,0,1) y<-rnorm(100,0.2,1) density(x) # This produces the summary of dependent variable and independent variable. How can I get the individual values of variables and reform a curve to calculate the area under

Hi R! I am reading in a text file which has one column of alpha data and 5 columns of numeric data. There is a header row. I would like the alpha data column to just be character rather than factor. Is there a way to do this, please? I'm thinking that it might be I() but can't figure out exactly how. Thanks, Laura mailto: lauraholt_983 at hotmail.com R 2.0.1 Windows

hello, i wonder how is string represent in R. if i have a string s= "hello", how can i refer to first character in the string s? also if i have s1 = "hello.1", s2 = "ok.1", how can i separate the s1 into "hello" "1" and s2 into "ok" and "1"? I have tried to use the substring function, but i don't where i can get the index

Hi all Is there any reason why the parameter i in a "for" loop ignores a value of zero? For example sim=c() p=.2 for(i in 0:5) {sim[i]=dbinom(i,5,p) } sim [1] 0.40960 0.20480 0.05120 0.00640 0.00032 In this example the quantile i= 0 was ignored since dbinom(0,5,p) [1] 0.32768 The same behaviour occurs if I use a while loop to perform the same calculation: sim=c() p=.2 i=0
