i trying reset autoincrement field of particular field. reason because gets count auto populates in case number. when hits mindnight 12/31/2013 11:59:00 pm want autoincrement start again zero. this code have. code on form1 , value of id2 form2 keep case number consistant when hit @ field1 using double click private sub field1_dblclick(cancel integer) docmd.openform "form2",,,,acformadd,achidden me.field1 = format(date, "yy") & "-" & format(forms!form2!id2, "0000") me.field2.setfocus end sub maybe has different approach. counting upwards. problem have when reach "12/31/13 11:59:00 pm" want autoincrement reset 1 start brand new case number. format provided. right know works fine format see yy-0001 in order words 13-0001 case number example. have following code think should work reseting autoincrement. has better approach this. code. private sub field1_dblclick(cancel integer) if me.text5 > "12

question parts: is there "julia way" implement sliding window? what needed in julia ignore nan s? there matrix 264 recording points (rows) , 200 time points (columns). want median correlation of each recording point every other point on 10 sample window. i've tried matlab-way (tm) creating 3d 264x264x10 matrix third dim correlation window. in matlab, median(cors,3) julia can mean(cors,3) . median not have support this. looks mapslices(median,cors,3) might want, recording points have nans. in r, might na.omit() or function options na.ignore=t don't see julia. #oned=readdlm("10152_20111123_preproc_torque.1d") oned=rand(200,264); oned[:,3]=nan; oned[:,200]=nan windows=10 samplesperwindow=size(oned,1)/windows cors=zeros(size(oned,2),size(oned,2),windows) i=1:windows startat=(i-1)*windows+1 endat=i*windows corofsamples=cor(oned[startat:i*windows,:]) cors[:,:,i]= corofsamples end med = mapslices(median,cors,3) # fail b/c nan here

a typical socket program example this: while(1){ data = socket.recv() //do work } since don't know when package arrive,it must block wait until data listening port,suppose if program start heavy work after received command side,during work , package arrived,but because @ moment doing work,you not listening port, might missed package ,no matter how fast handle work. so how socket work handle data without lost? the operating system has receive buffer holds packets have been received network not yet recv() ed application. if buffer fills packets lost. don't have in recv() call when packets arrive, though should make sure call enough keep buffer overflowing.

i'm trying run sequence of disk-based, old-school avi animations (a b c...), back-to-back, nice transition in between. i'm looking little guidance admittedly not having done threading work time, , never having done nsoperation or gcd . these animations run @ 30fps , typically less minute in duration, along coreimage -assisted transition in between. timing-wise, things pretty tight, multi-threading needed. since i'm using ssd disk-access, read rate (theoretically) @ double consumption rate, there's still chunk of post-read , pre-display processing occur lag whole process if singly-threaded -- not mention being bad idea. here's flow: firstly, read starting frame(s) of animation (possibly using serial nsoperation queue these reads). have raw data in nsmutablearray of objects. then, each frame that's been read, convert data in array coreimage format (either using similar separate serial "rendered" queue, or completion handler on each fram

i seem have issue our cart , unsure if it's theme related or not! error/normal messages (local or global) showing twice on front end. not sure causing issue. doesn't mater if i'm adding cart, editing cart, deleting item cart, changing address - messages showing twice. i looked through error logs , nothing shows up. has else had issue magento? i'm using 1.7. thank you! seems issue theme. magento has block called global_messages, maybe theme renders block twice, although flash messages. if see messages in cart should in theme layout folder in file checkout.xml, of these lines: <block type="core/messages" name="global_messages" /> <block type="core/messages" name="messages" /> try deleting 1 or both if find them.

i want use akka in application multi processing. so, same block of code gets executed each actor , results aggregated listener. so, question there synchronisation problem in case. if not how being handled akka actors internally. by default there should not synchronization problems - if strictly respect actor approach. means actors should communicate using messages contain immutable objects - , should never expose internal state of actor outer world directly. make internal state mutable/readable solely reacting received messages. each actor executed in own executioncontext. means each actor has own private state. akka actors designed in way accessing internal state "outer world" not possible (or made hard) since after creating new actor, have intermediary reference actor (an actorref instance), not reference actual actor instance in memory. intention of akka developers way: made hard developers the actual reference , access properties directly - break actor ap

i quite confused how memory allocation (malloc/calloc) works in linux/c. suppose, have machine 16gb ram , run program root. 64-bit machine, 16gb can addressed single segment. can allocate of (less amount os of course) single malloc call? many malloc calls? how relates "heap memory" , "virtual memory"? if allocate small memory chunk, , happens in heap memory, resize (enlarge) chunk, happens when approach stack area? do have fiddle setrlimit rlimit_as if want (almost) ram assigned single process, thought it's running root? a 64-bit process can allocate of memory. doesn't need root, unless system has defined ulimit setting non-root users. try ulimit -v see if limit set. under linux default settings process can ask amount of memory , granted. memory assigned used, , come physical ram or disk swap needed. a memory allocation resize done in c library allocating new, larger size , copying old data new allocation. not done expanding existing a

i using request params in application transfer information other websites. request looks like: myapp.com/users/sign_up?customer=somevalue once user isn’t logged in, works fine , able retrieve these params in registrations controller (i have overridden devise's controller). them using: customer_key = params[:customer] once user logged in, cant retrieve these params , suspect devise has modified them me. "post-login" params are: {"action"=>"show", "controller"=>"users", "id"=>"my-user"} (this taken users controller) my question - how can retrieve these params when user logged in in users controller? you have create require_no_authentication method in overridden registrations controller. devise::registration controller have before filter prepend_before_filter :require_no_authentication, :only => [ :new, :create, :cancel ] that checks if user logged in or not , if redirect
