How many POSIX shared memory blocks/handles is feasible on Linux? -

-

i want split shared memory in reasonable pieces, have no idea, number good? 100 shared memory handles 1 application reasonable number?

p.s: have produces/consumer problem. producer writes data in shared memory, 1 or many consumers read data time-shifted. producer , consumers should never access same data-block. consumers may try access , modify same memory-blocks. consumer access should managed semaphores.

the single data-block ca. 30kb , entire shared memory 1gb. using ca 100 pieces sure prevent locking producer/consumer , minimize number of locks required among consumers.

SoapUI on windows 10 - high DPI/4K scaling issue -

-
Image
soapui doesn't seem dpi-aware , displays small on high dpi screen (tiny text , buttons). other applications running fine (screen resolution 3840 x 2160). version : soapui 5.1.2 os : windows 10 i have tried: configure soapui run "disable display scaling on high dpi settings" - parts of soapui looking bigger , don't display (image) changing resolution changing font size (preferences > editor settings > select font...) therefore assume, soapui pretends dpi-aware, not scale itself. have same issue? this workaround until developers round making version dpi-aware. step 1: add registry key hkey_local_machine\software\microsoft\windows\currentversion\sidebyside\preferexternalmanifest (dword) 1 step 2: add manifest file 'soapui-5.2.1.exe.manifest' in same directory 'soapui-5.2.1.exe' content of manifest file: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <assembly xml...
