I'm pleased to announce the 19.0.0 release of xf86-video-amdgpu, the Xorg driver for AMD Radeon GPUs supported by the amdgpu kernel driver. This release supports xserver versions 1.13-1.20. Highlights: * Support for FreeSync variable refresh rate (this also requires the amdgpu driver from kernel 5.0 or newer, and radeonsi from Mesa 19.0 or newer). * Various TearFree related fixes and

Example: > d1 <- difftime(Sys.time(),Sys.time()) > d2 <- 1 * difftime(Sys.time(),Sys.time()) > d3 <- difftime(Sys.time(),Sys.time()) * 1 > d1 Time difference of 0 secs - thats fine > d2 [1] 0 attr(,"units") [1] "secs&...

I'm pleased to announce the 19.0.0 release of xf86-video-ati, the Xorg driver for ATI/AMD Radeon GPUs supported by the radeon kernel driver. This release supports xserver versions 1.13-1.20. Highlights: * Various TearFree related fixes and robustness improvements. * Up to six independent instances per GPU are now supported in "Zaphod" style multi-head configurations. Plus other

Hi, I have a sparse Matrix (kronecker product of spline design matrices), and I need to multiply each row by a number to get another matrix. If the matrix is A and the numbers are stored in a vector k, with plain vanilla matrices I would do A*k But when using the Matrix package (class of A is "dgCMatrix"), I get the warning "coercing sparse to dense matrix for arithmetic".

Introduce accessors for TTM buffer object memory that has been mapped into the kernel virtual address space or as IO memory. IO memory needs to be accessed via special accessor functions, not by dereferencing the iomem cookie. The wrappers hide the details of 32-bit access and honour the TTM map type. nv04_crtc_cursor_set() is changed to use the new wrappers. 'cursor' is received from

helo eveyone, for a rails app i''m working on i need to do some calculations with some floating point data. the calculations aren''t on currency so i can''t do the trick where you do the math with integers and have the units in pennies. i would like the results to be as accurate as possible with the least amount of work (haha). any suggestions? is there a ruby gem for more

Hi, R or S+ users, I want to make a simple transformation for the model, but for the whole design matrix. The model is distance ~ age * Sex, where Sex is a factor. So the design matrix may look like the following: (Intercept) age SexFemale age:SexFemale 1 1 8 0 0 2 1 10 0 0 3 1 12 0 0 4

I think we're ready for RC1 at this point, but wanted to give people a chance to scream about "just one more API change" until tomorrow. Let me know if there's something I'm missing; if I don't hear anything, I'll be tagging RC1 in the morning.
