...he hypervisor is unprepared for it. But, if the bit is _not_ set, we are under no obligation to reverse the order. Furthermore, all modern qemus set this bit. So, the "tell second" code is completely unused and untestable. Quoting Anthony: "untested code is broken code". This _also_ means that we don't have to preserve a pfn list after the pages are freed, which should let us get rid of some temporary storage (vb->pfns) eventually.

Since good server designs have come up in the past, I wanted to point out a "low-cost" server option that has good I/O, and the vendor offers _your_choice_ of not only Fedora Core or Red Hat Enterprise Linux, but _also_ CentOS _shipped_ with it! IN-A-NUTSHELL ... Starting at just over $750, you can get a single Socket-939 Opteron 1xx (dual-core is an option) system with up to 4GiB of ECC (but non- registered) DDR SDRAM, up to 4 hot-swap SATA bays (8114 model), one PCI- X slot (perfect for a 3Ware card, which th...

...pleted, but the factor U is exactly *> singular, and division by zero will occur if it is used *> to solve a system of equations. Accordingly, when INF0>0, determinant(A) behaves as det(A)=0, _not_ computing prod(diag(U)). The problem here is that DGETRF can _also_ give positive INFO for matrices containing NaN, which may very well not be singular for some finite value of NaN. I claim that, when INFO>0, determinant(A) should _not_ behave as det(A)=0 unconditionally, but rather sometimes (depending on some test) give NaN. Here is one case where 0 is really...

I've got a > pile of unused G4 400-800mhz powermacs just sitting around The ppc32 distro will work on any NewWorld G3, G4 based machine ( and 32bit ibm power, like the older rs6k's ) - it _also_ works fine on the MacMini and G4 Xserve's. With some common sense tweaks, a G4 450Mhz is a very usable machine running CentOS4 in 386MB of ram.

I started to try to use llvm::Error recently. This has nice runtime checks for if you didn't check the result, but I thought it would be really nice to get a compiler warning for the obvious cases of this rather than having to wait for a runtime check. This, of course, is exactly what the C++17 [[nodiscard]] attribute is for - with new enough compilers in C++17 mode we can just declare the

...for logging -- both stdout/stderr and actual log messages. (This is why journald is closely integrated.) There are other advantages (real dependency ordering, resource management/reservation with cgroups, etc.), but process supervision is the big deal. There are other alternative systems which _also_ do this, but overall, Fedora, openSUSE, Arch, Debian, Ubuntu, and others eventually decided that systemd was the technically best choice. -- Matthew Miller <mattdm at fedoraproject.org> Fedora Project Leader

...at will have use lists, and only local references are: - Argument - Instruction So the following does seem like a feasible minimal step forward: 1. Build a mechanism to break the use dependencies for GlobalValue and BasicBlock, i.e. allow immortal BlockAddress and ConstantGlobalValue values while _also_ allowing us to delete GlobalValues and BasicBlocks. For this mechanism, we can let ourselves be inspired by mlir::SymbolRefAttr, which uses strings for the linkage. Alternatively (and perhaps preferably), we could use a weak_ptr-like mechanism. This can be very efficient, since each GlobalValue a...

Redhat employs Lennart Poettering. Redhat derivates have to follow. Ubuntu and Debian choose systemd, on one hand, because more and more softs depend...

I have noticed a strange behaviour when our internet connection was down a couple of hours last week. What happens is that asterisk starts running *really* slow. If I type "sip show peers" it sometimes responds correctly and shows all the connected peers, but sometimes I get an empty list (this seems to go in cycles). Also the connected polycom phones seems to be unable to place any

...he server of their intent. If Note that this is independent of proposals made on the NBD list in the past [1] of having a way for the server to advertise that a particular export starts in an all-zeroes state (faster than a series of 32-bit NBD_CMD_BLOCK_STATUS would be able to do), although I may _also_ try to revive proposed documentation and a reference implementation of that optimization as well (as qemu-img convert can completely skip the zeroing, whether the bulk wipe or per-hole writing, when it knows the destination is already zero).
