Hi. Is it still considered risky to use the QEMU guest agent in an untrusted guest? A warning on these lines was written in the manual a few years back when the feature made its debut. I wanted to know if it was hardened since.

...n and have put together a little call platform and I'm stunned at the flexibility. There is one issue for me. I took me a while to click that ZAPTEL now equals Dahdi, but now I'm there I have an issue with the a X100 clone card that I have been told *not* to mention as I'm guaranteed a hostile response :-< So, I've put on my flameproof pants to ask a simple question: dahdi show status gives a red alarm. I'm guessing this means the card is unable to detect the battery. I've plugged a test but into the loop through on the card, dialtone is there. I've tried reversing th...

I'm trying to put together a poster using the LaTeX a0poster package and including some things from pstricks to get gradient shading, etc. The problem is that the default environments used by Sweave don't work where I need them. A simple code chunk like <<eval=FALSE>>= x <- 1 @ buried in a minipage within a psshadowbox gives the error Runaway argument? > x <- 1

Are the platforms with no function calls the same ones that have optimization-hostile barrier instructions? If the two sets of platforms are disjoint, OpenCL implementers can use my or Devang's noinline-function technique on the optimization-hostile platforms, and inject a unique argument into the barrier() call in the frontend on the no-function platforms.

A specific example is code like this (which is quite common): int ftoi(float F) { return *(int*)&F;...

Yes, this is the case. The platforms I'm thinking of don't support function calls and have the optimization-hostile barrier instructions. -- Mon Ping On Oct 9, 2009, at 10:46 AM, Jeffrey Yasskin wrote: > Are the platforms with no function calls the same ones that have > optimization-hostile barrier instructions?

Hi, Assume you are in hostile environment, as in you can't trust the DHCP serversss nor the TFTP/HTTP server. So you would want a checksum on kernel and initrd. Which checksum algoritme is available in pxelinux.0? Which checksum algoritme could be integrate into pxelinux.0? In other words: Please advice what could be done...

Hi, I'm looking for a good network device that does bandwidth management. It can be integrated in a router or stand-alone, but must be SIP-friendly. I`ve tried the DIR-655 (latest firmware is SIP-hostile, and the latest hardware revisions can't downgrade to the version that worked well) and the DI-724GU (SIP-friendly, but bandwidth management is automated and not configurable enough for my taste), both from D-link. What else is out there and allows me to do upstream QoS on cable/DSL links?...

I''m trying to use new_equipment_path, which creates the appropriate link. But, when trying to evaluate "equipment/new" I get the error below. I''ve included my routes (rake route). Equipment is one of those words that pluralizes to "equipment", so the singular is right (from what I know from this forum. Any help would be appreciated. Error: equipment_url

That can be it being done in a way that isn't 3/4 bailing wire and duct tape or it could be that the have a viable set of tools which can be done cleanly and meet various security uses which require knowing what the hostility of the environment is. AKA it may work if you expect no hostile VMs ever to be installed or it may mean it works in a hostile environment where VM A and VM B are owned by different actors and they are actively spying on each other. Each of those has different requirements and outcomes. AKA in one you can expect that secrets in the vTPM may remain secret while t...

Peter Anvin on Tues Nov 18th, 10:24:15 PST 2014 explained this pre-Linux-3.3 kernel problem well. It was a discussion of grub2 booting the kernel in a "hostile" way -- not using the built-in kernel EFI bootloader. And thus, grub2 is able to boot earlier kernels, while syslinux follows the rules. And is not able to. H. Peter referenced https://www.kernel.org/doc/Documentation/efi-stub.txt for a fuller explanation. Great job writing up documentatio...

Hi everybody, recently I had to teach a course on Cox model, of which I am not a specialist, to an audience of medical epidemiologists. Not a good idea you might say.. anyway, someone in the audience was very hostile. At some point, he sayed that Cox model was useless, since all you have to do is count who dies and who survives, divide by the sample sizes and compute a relative risk, and if there was significant censoring, use cumulated follow-up instead of sample sizes and that's it! I began arguing that i...
