similar to: Scalar vs. vector

I have been comparing R with other languages and systems. One peculiar feature of R is there is no scalar. Instead, it is just a vector of length one. I wondered how much performance penalty this deign cause, particular in situations with many scalars in a program. Thanks.

Hi all, I'm implementing a virtual processor which features dynamic register indexing, and I'm struggling to make LLVM 3.0 produce good code for it. The register set is implemented as an LLVM array so it can be dynamically indexed using GEP. However, most of the time the virtual processor's registers are just statically indexed, and so I expected/hoped the code would be as

I have a regular script I run to make static "snapshots" of my home file system, with each being all the files that changed in the past 24 hours. I just moved my home partition to a new harddisk w/more space. I ran the util and have gotten odd results each time I ran it. This one bothers me... as I'm not sure why the attrs would be missing. How can the names be transfered but no

I am curious as to why LLVM has explicit support for 1 element vectors, for example 'v1i32'. Are there some contexts where handling a value as a 1 element vector can yield better code quality than the corresponding scalar 'i32'?

I am needing to return i128 as a shadow return due to abi issues on alpha.  The problem I am running into is the code for doing that with scalars (currently only used for vectors, as far as I can tell) sets the sret on the parameter.  If I just go this path, then I am setting sret on an integer pointer, which verify objects too.  LangRef doesn't say scalars are allowed to have sret set, but

Here's what I'm trying to do. I have a spam filtering operation as a front end for other servers. I've created a virtual server for spam storage where the user will be able to log in using squirrelmail/dovecot to review and release their spam. The email is stored in maildir format. Piecing it together I can use squirrelmail to pipe the email into something so that if a use finds a

I am using Rsync to mirror my primary drive to a mounted second drive. I am using a crontab to control it: 30 3 * * * /usr/bin/rsync -rpogl /* /mnt/backup2/systemBackup/ The first run seems fine. But the subsequent running seems to double the original directory size. I notice this by running df -k. The destination size increases two fold, as if each time Rsync runs, it repeats itself, rather

Unfortunately, some data I need to work with was delivered in a rather messy Excel file. I want to import into R and clean up some things so that I can do my analysis. Pulling in a CSV from Excel is the easy part. My current challenge is dealing with some text mixed in the values. i.e. 118 5.7 <2.0 3.7 Since this column in Excel has a "<2.0" value, then R reads the

Hello R-list, I am trying to calculate a ridge regression using first the *lm.ridge()* function from the MASS package and then applying the obtained Hoerl Kennard Baldwin (HKB) estimator as a penalty scalar to the *ols()* function provided by Frank Harrell in his Design package. It looks like this: > rrk1<-lm.ridge(lnbcpc ~ lntex + lnbeerp + lnwinep + lntemp + pop, subset(aa,

i am looking at using btrfs for a new project and i have a few questions:     * i have heard that as it currently stands Btrfs has some issues to be used as a Lustre file system; is he aware of the issues and any plans to address these and integrate Btrfs in to Lustre     * any plans to support native clustering on Btrfs     * on ZFS the ZIL is a separate device, any plans to implement a the

I'm having trouble figuring out how to make a bridge that does not block forwarding of packets when there is no receive channel in the same bridge. The reason I want to do this is that the return path is via another circuit. The two directions are on two different radios. I would think this would be like the response given to someone in July 2007 about setting a "hub" mode by

I was surprised to find that the variance of a scalar, using var(), is NA. Surely this should be zero?

I downloaded the latest wine from the cvs site and ran its ./tools/wineinstall. It ran for quite a while and croaked on /wine/server/semaphore.c. Basically, gcc says "Internal compiler error: program cc1 bog fatal signal 11". The compiler is 2.91.66 (aka egcs-1.1.2 release) and compiles other programs including 2.4.1 & 2.4.2 Linux kernels just fine. I am puzzled what 'fatal
