Hi, I've removed this dmbroline spammer from the Google group. However, it seems like there is no way to ban them, or report them as a spammer or anything else, with the new Google groups, like there used to be. William On Thu, Mar 29, 2012 at 2:53 AM, dmbrol...@gmail.com wrote:

Actually the 404 error sais that you alreade got past the firewall and have reached the server so the trouble should be somewhere else indeed. Does the 404 error say more (i.e. does it say what is not found?). A screenshot might be usefull. p.s. I assume that you don't already have your own

Is the quad precision qd library (http://crd-legacy.lbl.gov/~dhbailey/mpdist/) included in Sage? Which version? How to use it from Sage? Particularly, I need to split a 35-digit floating point constant, given as astring, into doubles[2] in the way QD library does it. Thanks Igor -- To post

In the long term I think it would be nice to have gcc 4.6 libquadmath wrapped into a Sage ring. Note: this is 128-bit float, not quad double = 256-bit float. Since it is part of gcc, I expect the quality and speed to be quite good, but I haven't benchmarked it against mpfr. -- To post to

When you get the 404 error, there is usually some fine print about which server replied with the error. Maybe that'll give you some hint of what is going on. On Thursday, March 29, 2012 8:19:05 PM UTC+1, Matthias L wrote: No, http://127.0.0.1:8000 doesn't work either ... as far as I know
