    Have to admit I've always been kind of curious about how Itanium actually performed in the wild, although I think its long, drawn-out death rattle gives a fairly good indication....

    Re: BranchScope: Here we go again with the Spectre like attacks

    Another vulnerability has apparently appeared:

    https://www.reddit.com/r/sysadmin/co...otal_meltdown/
    https://blog.frizk.net/2018/03/total-meltdown.html

    Did you think Meltdown was bad? Unprivileged applications being able to read kernel memory at speeds possibly as high as megabytes per second was not a good thing.

    Meet the Windows 7 Meltdown patch from January. It stopped Meltdown but opened up a vulnerability way worse ... It allowed any process to read the complete memory contents at gigabytes per second, oh - it was possible to write to arbitrary memory as well.

    No fancy exploits were needed. Windows 7 already did the hard work of mapping in the required memory into every running process. Exploitation was just a matter of read and write to already mapped in-process virtual memory. No fancy APIs or syscalls required - just standard read and write!


    Those despicable Elk,stealing the pond weed!

    My work still has two itanium boxes that are 'running', we do not like it when customers, who still use it!!!, want support.

    I used one once. The hard drive failed, usually not a big thing, but in this case we just shrugged and whilst no-one would throw it away we left it turned off. It was OK, but for that money you expect rather more than just "OK".
