i trying python based web scraping execution time pretty critical. i've tried phantomjs, selenium, , pyqt4 now, , 3 libraries have given me similar response times. i'd post example code, problem affects three, believe problem either lies in shared dependency or outside of code. @ around 50 concurrent requests, see huge desegregation in response time. takes 40 seconds 50 pages, , time gets exponentially slower greater page demands. ideally i'm looking ~200+ requests in 10 seconds. used multiprocessing spawn each instance of phantonjs/pyqt4/selenium, each url request gets it's own instance i'm not blocked single threading. i don't believe it's hardware bottleneck, it's running on 32 dedicated cpu cores, totaling 64 threads, , cpu usage doesn't typically spike on 10-12%. bandwidth sits reasonably comfortably @ around 40-50% of total throughput. i've read gil, believe i've addressed using multiprocessing. webscraping inherently slow thi

i have question copying file current application directory directory , subfolder. for example, want copy file current application working directory\files\settings.ini , want copy documents\subfolderexample\settings.ini what came is: my.computer.filesystem.copyfile(my.application.info.directorypath & ("files\settings.ini"), my.computer.filesystem.specialdirectories.mydocuments & "subfolder\settings.ini") but doesn't seem work me @ all. i fixed it! brother working on code before me later today put "try" thingie reason , doesn't want copy file way. removed try thingie , it's working fine now.

i have relativelayout , want save content bitmap . there tonns of solutions here no 1 suits task. main difficult view has, lets say, 700x900 px size. want screenshot of view size 1000x1000. cannot make screenshot getdrawingcache() , scale because views inside relativelayout shrinked/stretched. think need resize view itself, make bitmap it, , resize back. but! if resize view bigger screen , getdrawingcache() works visible part of view. cannot put scrollview workaround such behaviour. appreciated.

lets solution has 2 projects: the first called "mainproject" (a .netstandard 2.0 project). the second called "mainprojecttests" (a nunit test project) unit tests each class "mainproject". the first project (mainproject) has nuget dependency called "dependencyx". obviously, project "mainprojecttests" has reference "mainproject". so when test runner runs test of "mainprojecttests" calls methods "mainproject" using "dependencyx" i'm getting system.io.filenotfoundexception exception: system.io.filenotfoundexception : not load file or assembly 'dependencyx, version=1.0.0.0, culture=neutral, publickeytoken=null' or 1 of dependencies. why getting exception? when add "dependencyx" "mainprojecttests" works fine, seems me not practice... how solve it? i'm using visual studio mac community 7.2 preview (7.2 build 583) thanks help. edit: tri

i confused if 'vary traits' right thing define different set of layout constraints portrait & landscape mode on iphone. objective have different layouts portrait & landscape modes on iphone (doesn't matter on ipad). tried 'vary traits' , define different set of nslayoutconstraints portrait & landscape modes seems not working. if have constraints p1 & p2 active portrait mode , c1 & c2 landscape mode same view, should job. 'vary traits' meant job? also how undo variations might have added using 'vary traits'? you need following - set constraint in portrait mode. select landscape mode. disable constraints set in portrait mode. assign new constraints landscape. go in portrait mode , disable constraints set in landscape mode. that's it. hope works. feel free comment if have confusion..

in past few days have been doing extensive testing of subversion different clients, operating systems, client , server versions , have noticed strange behaviour windows clients connecting linux servers, hitting them excessive cpu usage on sshd process, linux clients not exhibit behaviour. a sample test setup follows: server linux ubuntu 16.04.3 lts, openssh_7.2p2 ubuntu-4ubuntu2.2, openssl 1.0.2g 1 mar 2016, subversion version 1.9.3 (and 1.9.7). client tortoisesvn 1.9.7 when checking out large repositories linux server hit on sshd process, process running 100% cpu usage. in effect slows down performance , speed @ checkout runs. linux clients connecting same server not cause load on server. this happens when compressions turned off , when encryption cyphers changed, different versions of subversion. behaviour identical. i'm not sure address issue not happens tortoisesvn sliksvn well. direction appreciated. if you're looking way controlled set of users access
