i using salesforce workflow send out product information , invoices clients running problems thinking of how verify if client receives email , or opens it. there way prove client received inventory list or invoice? doing prior research on subject have come across following suggestions: adding 1x1 invisible image email unique id adding regular image instead of 1x1, maybe company logo having recipient click link see invoice with these solutions, have detect image requests or link request them , extract/produce unique id each client. not sure how in salesforce appreciated, along other detection ideas. if have salesforce content, there ways expose documents clients features need. you'll send email link , later can track confirmation of opening, count how many times downloaded.. can set expiration date document (can't downloaded anymore after date). as "pure" email apex/visualforce , manually recreating content's functionality... nowadays mail cl...

i'm using jquery in app registers user clicks perform given action through .click() binding, , want functionality available only through user mousedown. 1 of friends pointed out today it's possible run $(element).click() javascript terminal in firebug (or similar), , achieve same functionality clicking on element -- i'd prevent. ideas on how go doing this? input. short answer: no, can't prevent it. long answer: event click event bound such called event handlers . handlers functions executed when given event occurs. if click on element, browser checks if event handlers bound it, if fires them. if not, browser try bubble up event parent elements , again checks if there event handlers bound kind of event .. , forth. jquerys .trigger() method (which call if calling .click() instance) same thing. calls event handlers bound specific element, specific event. edit there might simple ways somekind of soft detect real click, instance might check...

i'm trying find way deploy software custom patches in production. base software opensource own repos (svn) , we've got patches select 1 service , not other (so we've got base+patcha+patchb on 1 server , base+patcha+patchc on another). everything deployed packages, pretty simple. issue i'm thinking is: how store modifications? these ways thought about: i've tried using quilt / patch series + downloading specific revision upstream when building. works well, until need port patches new version. since quilt needs copy of tree patch modifications, takes long time fix stuff. also, having different versions deployed on different servers means need have different build-scripts. i clone repository local git/hg , create branch local modifications. that's great porting patches forwards , can make local release tags on branch, unfortunately lose information separate patches. can see diff upstream of course, lose clear separation of different local modifications. ...

all, i have php5 application written zend framework , mvc style. application allows multiple users login , see content based on privileges. have dropdown on home page. upon selecting dropdown, ajax call occurs populates page table. also, generates pdf file table data using mpdf library. there link called "download pdf" in page allow user download generated pdf. my question is, in such environment, how best serve pdfs multiple users? should serve single pdf common name or should create multple pdfs based on dropdown value (looks overkill)? don't want let users see each other's pdfs. also, should store pdfs pretty entire application directory have 750 acccess. thanks, user clicks "downlod pdf" parameters id sent ajax is there cached version of pdf id saved? ok, show user; else: generate pdf cache it show pdf user i have cache key userid-documentid (user1-document1 example) , name document make them recognize in "downloads fo...

i wish stop tracking files still keep them in working tree. i've gathered git rm --cached file let me that. however, if else pulls change, their local copies deleted? yes, copies automatically deleted. imagine if deletion wouldn't happen--then working copies of users polluted piles of deleted files, aren't needed anymore. however, if remote users made local changes these files, won't deleted, since pull result in merge conflict. as jefromi suggests in comment, while files removed @ other users' sides, can restored--they're under version-control, aren't they? ;-) files gotten git checkout <revision> -- <files...> . revision may specify id of previous commit, pull it's saved in orig_head (see this question details): git checkout orig_head -- removed_file

is possible manipulate images using canvas? how image onto canvas? @override protected void ondraw(canvas canvas) { bitmap bitmap = bitmapfactory.decoderesource(getresources(), r.drawable.icon); bitmap mbitmap = bitmap.copy(bitmap.getconfig(), true); canvas = new canvas(mbitmap); matrix matrix = new matrix(); canvas.drawbitmap(mbitmap, matrix, mpaint); } i'm unable see image on screen. canvas.drawbitmap() shouldn't necessary since i'm using constructor , passing mbitmap. yes can, don't "get image onto canvas," canvas interface draw onto bitmap. so, create canvas , give reference mutable bitmap: canvas c = new canvas(mybitmap); very easy :)

what trying achieve complex privacy routine, have following tables. posts posts_privacy privacy_global followerlist we have news feed sort of thing on our site, gets 10 latests posts people user following, there 3 levels of privacy, first privacy_global user can set privacy options on posts , 0 , 1 , 2 "only me", "everyone", "followers only" respectively, there posts_privacy user can choose list people wants show or hide post before posting it, setting overrides privacy_global settings , posts_privacy instead if set. now problem that, when apply privacy in news feed using php ask posts this. select `post`.*, `users`.`fullname`, `users`.`username`, `posts_privacy`.`hide`, `posts_privacy`.`show`, `post` left join `posts_privacy` on `post`.`id`=`posts_privacy`.`postid` inner join `users` on `post`.`userid` = `users`.`id` (`post`.`userid` in (1,2,3,4,5,6) , 12 not in ( select `hide` `posts_privacy` `postid`=`post`.`id`) or `s...

i'd invoke bash using string input. like: sh -l -c "./foo" i'd java. unfortunately, when try invoke command using getruntime().exec , following error: foo": -c: line 0: unexpected eof while looking matching `"' foo": -c: line 1: syntax error: unexpected end of file it seems related string not being terminated eof. is there way insert platform specific eof java string? or should looking approach, writing temp script before invoking "sh" ? use this: runtime.getruntime().exec(new string[] {"sh", "-l", "-c", "./foo"}); main point: don't put double quotes in. that's used when writing command-line in shell! e.g., echo "hello, world!" (as typed in shell) gets translated to: runtime.getruntime().exec(new string[] {"echo", "hello, world!"}); (just forget moment shell has builtin echo , , calling /bin/echo instead. :-)) ...

what made hard find? how did track down? not close enough close see also https://stackoverflow.com/questions/175854/what-is-the-funniest-bug-youve-ever-experienced a jpeg parser, running on surveillance camera, crashed every time company's ceo came room. 100% reproducible error. i kid not! this why: for doesn't know jpeg compression - image kind of broken down matrix of small blocks encoded using magic etc. the parser choked when ceo came room, because had shirt square pattern on it, triggered special case of contrast , block boundary algorithms. truly classic.

i got 1 of these gyros, http://www.xheli.com/wag0diadpiin.html . it has 6 pins 3,3. i'm afraid might harm device, wanted ask here. how should connect arduino? , code should use? i have salvaged 1 of these off old walkera helicopter , want same thing. if no 1 has posted here, try sort out , post reply. for it's worth, female 3 pin connector connects walkera brushed speed controller (which in turn connects 6-15 v battery power). other 3 pins connected main circuit had radio control , servo outputs. connector must have pin sample. speculating, guess work best connect int0 or int1 on arduino, instead of trying poll it. i guess 2 axis values might come chip, problem knowing how data encoded/muxed on single output pin. if find out more, post update. luck.

i'm developing operating system , rather programming kernel, i'm designing kernel. operating system targeted @ x86 architecture , target modern computers. estimated number of required ram 256mb or more. what size make stack each thread run on system? should try design system in such way stack can extended automatically if maximum length reached? i think if remember correctly page in ram 4k or 4096 bytes , doesn't seem lot me. can see times, when using lots of recursion, want have more 1000 integars in ram @ once. now, real solution have program doing using malloc , manage own memory resources, know user opinion on this. is 4k big enough stack modern computer programs? should stack bigger that? should stack auto-expanding accommodate types of sizes? i'm interested in both practical developer's standpoint , security standpoint. is 4k big stack? considering normal program execution, point of view of classes in c++, notice source code tends malloc/new data...
