i have developed plugin has extension point listviewcolumn have run problems when combining plugin, nested view plugin . my plugin enables 1 select jobs in current view , make modifications 1 button press. when view resides inside nested view, can't find view (from java code , jelly scripts) , no modification can made. in columnheader.jelly execute ${it.getheadertext(view.name)} where getheadertext() defines as public string getheadertext(string viewname) { hudson.getinstance().getview(viewname); // access jobs return object of .getview(viewname) return viewname; } this works fine regular list views whenever enter nested view's list view, getview(viewname) returns null. upon further investigation i've noticed nested views show when calling hudson.getinstance().getviews(); which returns views in toplevel of whole jenkins instance (no views inside nested views). here have nested view shows , instance of hudson.plugins.nested_view.nestedview.

i designing multi-threaded piece of code includes part several sensors queried (through socket), , data stored first in vector , subsequently written db. the entire process time sensitive since each sensor updates every few seconds new data. if data not retrieved in time, lost. currently, have vector of (custom sensor data) class stores information obtained , each of sensors. the plan open thread each sensor (say, 40-50 in total, not want limit number in case more sensors added later) , have access , fill particular (set index of vector) cell of vector. is such operation on vector allowed , prudent? also, knowing peculiarities of tcp/ip sockets, drastically speed process introducing threads (as opposed to, say, running in single thread)? there better or more elegant way of doing this? from write seems queue beffer fit; threads push sensor data on queue , later (perhaps thread) can take elements queue , process them. java (at least version 7 , 8) offers different qu

my experience of version control systems clearcase and, while it's served purpose well, move free tool. i've read , experimented git & svn , see advantages in commit based approach opposed file based approach clearcase uses. however, there parts of clearcase miss if there no equivalent in other tools. clearcase distinguish between files written user , files created programs user had written. user written files 'file element versions' , program generated files 'derived object versions'. furthermore dependencies of 'derived object version' determined using clearcase cleartool catcr command. my question is: there equivalents these files types in git , there equivalent of cleartool catcr command? agree isn't strictly part of version control system, still replicate if moved git. the cleartool catcr there use metadata (the configuration record or crs ) attached derived objects (the .o files), generated clearmake . this use

i try improve perfomance of program. used jmh comparate 2 versions don't know if there real difference. example of results: version1(op/s) score error(op/s) version2 score error benchmark 1 12382150,338 1277638,481 18855038,903 50835,395 benchmark 2 11708047,2 4061755,193 18843828,659 41966,689 benchmark 3 7814465,4 9483927,071 18821356,961 72364,651 benchmark 4 10481146,451 464691,58 13936537,089 40726,506 benchmark 5 6863734,072 175974,219 9709381,687 21774,816 can results show real difference between version 1 , version 2? iirc, benchmark score (ops/s) arithmetic mean of 90% distribution (that is, extreme outliers filtered out). thus, no matter how slice it, version 2 scores higher on benchmarks.

to explain issue, dad teaches english , switched him on linux, works apart teaching cd uses. i figured out shortly later cd mess of flash files, , putting on webserver meant use cd without official launcher (there 1 linux doesn't work) so ran folder : python3 -m http.server and sure enough loaded fine, issue case sensitivity. i don't know coder doing, in swf (it's flash), calls xml files first letter capitalised, files not capitalised, therefore python's web server 404's due case). i'd avoid having change each file i wondering if possible tell python's webserver ignore case entirely when processing requests ? i should note i'm using python3 any appreciated ! if files in server root (including eventual subdirectories) lower case, easiest override translate_path method of simplehttprequesthandler unconditionally operate lower case paths. simple example: from http.server import httpserver, simplehttprequesthandler class low

i want make sure users wont able push formats. check file format before uploading file gitlab server. web hooks affects specific project, while want whole server filtered. idea? ok, found out do. used hooks. can add own script inside path: /opt/gitlab/embedded/service/gitlab-shell/hooks/ you can edit existing samples. wrote in ruby , script in bash, make sure add "#!/bin/bash" (or whatever script language write) file header. make sure bring file chmod 755 or higher, , file name should event name (without format, "pre-rereceive" example). notice parameters, can read in "pre-receive.sample" notes. luck.

is possible evaluate expression nested variables in selenium ide? example: store | 2 | scenario store | $10 | data${scenario}cost so data2cost = $10 store | ${data{$scenario}cost} | ${scenario}result echo | ${scenario}result | which returns 2result = ${data2cost} opposed 2result = $10 . you can use storeeval store evaluated expression variable tutorial helped me achieving that |store | 2 | scenario | |store | $10 | data${scenario}cost | |storeeval | storedvars['data${scenario}cost'] | ${scenario}result | |storeeval | storedvars['${scenario}result'] | mainresult | |echo | ${mainresult} |

i making use of 2 jquery scripts in page made of repeating elements (a gallery of thumbnails basically). scripts @ end of html page in 2 separate script tags. the first calls script making use of touchtouch plugin presents images in nice overlay , allows swipe navigate. the second infinite ajax scroll appends more items page scroll down. the problem seem having when page first loads, touchtouch script modifies thumbs present on page. scroll , infinite scroll script appends more thumbs, newly appended thumbs not modified touchtouch script, not function should when clicked on. how make touchtouch script run again after infinite scroll script has added new elements page? here snippet end of html <script src="assets/touchtouch.jquery.js" type="text/javascript"></script> <script> $(function(){ // initialize gallery $('#thumbs a').touchtouch(); }); </script> <script type="text/javascript" src="assets/j

i want customise 1 uitextfield reason. subclassed , added few methods. instead of can use extension on uitextfield ? approach ? please explain ! as general rule of thumb (ymmv): are adding general-purpose functionalities should available every uitextfield ? if so, make extension. uitextfield instances can call new methods. are adding functionality should restricted special instances of uitextfield identify precisely? if so, make subclass. instances of subclass can use new methods. there other technical considerations, extensions can't add fields, instance.

i have form has 5 file inputs create array of images. when processing, wish loop through images , process them. $images = input::get('images'); // image proccessing foreach ($images $image) { print_r($image); } that output file name, if call move function on $image variable "method move called on string". how should doing this? you should doing $input = input::file('files'); //get file input //check if input has file if ($input){ foreach($input $key){ //loop through file , perform action... $array = image::file_upload($key, 'file', 'images'); // assume have method upload above $key = $array['filename']; print_r($key); } } $this->image->save($input); //save db file name.

for report creating need take 2 separate expressions , combine them 1 solution. the first expression need total sales calculated by sum([dct].[quantity_stk] *[icp].[unitcost]) [total sales] the second expression need total cost which calculated by max(cast ((@purchasecost + @prod_costlbs) * @inputweight decimal (18,2))) [cost] both of statements work because used other columns in query , display properly. in order find out total profit tried combine 2 using sum, avg, max , trying make expression results in error. believe code below has right idea, missing important parts. perhaps over() statement: cast (([dct].[quantity_stk] *[icp].[unitcost]) - ((@purchasecost + @prod_costlbs) * @inputweight) decimal(18,2)) [profit] the problem have is calculating profit each row want total profit. make aggregate function believe. or there way store other 2 expressions variables , use those? i using microsoft sql server 2005. full code: set nocount on; declare @purchasec

i trying develop custom select binder not able understand how develop update functionality. this have done. want custom binder handle type of data [{ message: "hello", value: 1 }, { message: "hi", value: 2 }, { message: "bye", value: 3 }, ] the problem, understand it: using bootstrap fullscreen select , , can initialize it, when select new value, no observable gets updated. basically, need know when new value selected. since way widget works pop screen of options , allow select one, , close popup, and widget provides ability onclose callback, that's need. i'm using standard convention of value binding in select. when widget closes, if new value different bound value, update bound value new value selected in widget. ko.bindinghandlers.menu = { init: function (element, valueaccessor, allbindingsaccessor, viewmodel) { var valueobservable = allbindingsaccessor().value; $(element).mobi

in nutshell : i got distribution profile in keychain (image 1) from xcode developer account preferences see developer profile (image 2) when try add new ios distribution profile says 1 , should visit member centre (image 3) i did , brings me step 1 infinite loop (aka "i'm stuck here keep retrying..") edit: when try use ios mobile distribution profile generated don't see many options code signing identies. how looks like: i have downloaded team distribution profile on computer apple developer member centre. way looks in keychain : however when try sign code ad hoc distribution cannot find distribution certificate in code signing identities tab. i manage build product archive (for local ad hoc distribution, e.g. testflight) when try export (or submit appstore) message saying have code signing identity , need download it. more details on in question asked yesterday . today trying different approach , decided go account->preferences , tr
