search for: uncooperative

I have a server running Red Hat Linux 5.2 with samba 1.9.18 installed (at least that's the rpm package). The server itself is mounting and sharing two SCSI cdrom drives - the kind that are capable of changing up to six cdroms each. The OS mounts the drives correctly. I can see the files. I have shared the drive contents and can map access to them over a Win95 network. I have set the

Hi all, I would like to implement GC for a language supporting multiple threads. There will be no shared state between threads as communication will be based on message passing. I do not care much about performance. The priority for me is to get things working. I have read LLVM guide on writing GC: http://llvm.org/docs/GarbageCollection.html. Shadow stack approach looks very promising. The

I am creating a new (very simple) one by keeping any live local reference variables on a shadow stack. That assumes an uncooperative environment but it is still precise. That will suffice for now. > I'm not a GC expert, so why are the current GC intrinsics insufficient?...

Sorry, I had some e-mail issues in March thanks to an uncooperative ISP and lost some mail.

Maybe it's just me, but I get the impression that Grandstream is quite uncooperative.

I'm having a problem installing CentOS 8 from a USB drive. When the installer boots from the USB, it displays the language selection screen. After I select English and continue, the installer freezes. The USB drive flashes a couple times over the next minute or so, the stops. The mouse moves the cursor, but the installer is unresponsive to either selecting QUIT or HELP. I've

...rs of the > programs which produce the bad WAVE files, tell your customers to > switch to compliant programs, As I have stated before on this list, that is a completely unrealistic fantasy. I have yet to find a customer who favorably responds to being told to change their tools. Dumping the uncooperative vendor is generally much easier. Customers don't want excuses, they want solutions. And as pointed out before, sometimes recordings get interrupted. If a recording device loses power it may not be able to write an even number of bytes or update the header size. Sending bug reports to the man...

That's true; the shadow stack design is explicitly for uncooperative environments, after all. When you want to eliminate the shadow stack overhead, you will need to (a.) use a conservative GC or (b.) emit stack frame metadata using the LLVM GC support. > Sorry I'm so lost...just trying to figure out what llvm does for me > and what I have to do....

...do you know if this USB is not a bum? The later explains why I could not my raspberry pi booting. Replacing with a new sd card solved this issue. If you want to be lazy and have a hypervisor, create an vm guest and boot it using the usb. With that said, it is possible that while you are having an uncooperative gui you can still switch screens (i.e. keyboard still listening to you) to screen 1 or 2 and then take a look at the dmesg/log output for clues of what went boink. > Details: > CentOS-8-x86-1905-dvd1.iso (sha256 verified) > ASUS Prime B350 Plus motherboard > AMD Ryzen 5 1600 CPU >...
