...info showed results as DOMAIN+username but somewhere along the line that change to just the username. Is that indicative of something I've misconfigured? Thanks for any insight. My gut tells me I'm not far off, but I've exceeded my "solve it myself" frustration level! Dave Lemire

A quick point of order here: arguing with Duncan in this forum is helpful to expose ideas, but probably neither side will convince the other; eventually, if you want this adopted in core R, you'll need to convince an R-core member to pursue this fix. In the meantime, a good, well-tested implementation in a user-contributed package (presumably written in C for speed) would be enormously

I have the impression that Lemire's method gives the same results unless it is correcting for the bias that exists in the current method. If that is really the case, then the disruption should be rather minor. The ability to fall back to the old behavior would still be useful, though. cheerio ralf -- Ralf Stubner Senior Soft...

Here is a quote from my friend. He uses XP most of the time because he hasn't been able to get the newest Adobe Photoshop working in Debian Sarge 3.1 with Gnome. He tried both cedega and the newest version of wine to get Photoshop working. Has anyone else got it working or know about getting it working?

For a well-tested C algorithm, based on my reading of Lemire, the unbiased "algorithm 3" in https://arxiv.org/abs/1805.10941 is part already of the C standard library in OpenBSD and macOS (as arc4random_uniform), and in the GNU standard library. Lemire also provides C++ code in the appendix of his piece for both this and the faster "nearly di...

By reading messages on this list, I think that I have figured out that in gnome, you should be able to find directories like media/floppy jerry@linux-8ldg:/media> dir total 0 drwxr-xr-x 2 root root 48 2006-08-18 20:18 floppy Since the only sub directory I have in the media directory is floppy, does this mean that I have not configured the computer correctly? I cannot get to the cd drive

(As per IRC discussion) I understand that the carry-less multiplication algorithm has it's uses since/and it is implemented as an instruction in many architectures and that adding it as a general-purpose intrinsic will allow us to drop target-specific intrinsics as by-product. What i do *NOT* understand is: what is the actual/main goal/driving factor of adding an LLVM intrinsic for it? The
