The 1000 vector sampling points created by v.random are shown as black dots. [*] trend-plane created by the r.cog addon for spearfish's elevation.dem this example is not completely wrong (as is the case in the earlier attached screenshot!), just a net of overlain noise on top. So there could be two bugs here. - http://bambi.otago.ac.nz/hamish/grass/bugs/v.surf.idw/vsurfidw.png - http://bambi.otago.ac.nz/hamish/grass/bugs/v.surf.idw/vsurfidw.slope.png - http://bambi.otago.ac.nz/hamish/grass/bugs/v.surf.idw/vsurfidw.pcurv.png - http://bambi.otago.ac.nz/hamish/grass/bugs/v.surf.idw/vsurfidw.tcurv.png note the strands of noise in the NW corner in the curvature maps, and the clump of it the center-right of the lower edge in the slope map. Try to match them with the r.surf.idw slope map below. for comparison, same-data slope map from v.surf.rst and r.surf.idw modules. - http://bambi.otago.ac.nz/hamish/grass/bugs/v.surf.idw/vsurfrst.slope.png - http://bambi.otago.ac.nz/hamish/grass/bugs/v.surf.idw/rsurfidw.slope.png r.surf.idw2 was very similar, but not identical, to r.surf.idw; so not shown. As expected, v.surf.rst is much smoother throughout although it suffers from edge-effects and stitching of the quadtree segmentation around the edges. This suggests the quadtree vector map should be created and the outer row of segments from it discarded.

[GRASS-dev] mapset permissions: only owner should have write permissions
From within GRASS, only the owner of a mapset is allowed to start a GRASS session in this mapset, i.e. only the owner of a mapset has write permissions to this mapset. But a new mapset being a folder in the file system is created with mode 0777, thus granting write permissions to all. I suggest to change mode from 0777 to 0755 in G_mkdir() and add mode = 0755 in gis_set.py. Any objections?

Re: [GRASS-dev] mapset permissions: only owner should have write permissions
Hi, Markus M: From within GRASS, only the owner of a mapset is allowed to start a GRASS session in this mapset, i.e. only the owner of a mapset has write permissions to this mapset. But a new mapset being a folder in the file system is created with mode 0777, thus granting write permissions to all. I suggest to change mode from 0777 to 0755 in G_mkdir() and add mode = 0755 in gis_set.py. Any objections? It's not created as 777 (I would have noticed that :), that's before the umask. So for me it gets created as drwxr-xr-x, as expected. $ man 2 mkdir: The argument mode specifies the permissions to use. It is modified by the process's umask in the usual way: the permissions of the created directory are (mode ~umask 0777). Other mode bits of the created directory depend on the operating system. [...] NOTES Under Linux apart from the permission bits, only the S_ISVTX mode bit is honored. That is, under Linux the created directory actually gets mode (mode ~umask 01777). See also stat(2).

I was just trying to compile grass7 on a new airbook that I am taking to Prague, and I can confirm hat there is a problem. Also, related to the tech preview, the current wingrass6.4.3svn and wingrass7 binaries from Martin crash on networked windows8 in our lab and for my colleague (the startup does not open) but run fine on the windows side of my student's Mac.
