i have program taking input external source (right now, joystick), , plotting on graph. graph displays last 60 frames of data, 1-2 seconds. here data input: nextdatapoint(double x){ if (x > max){ max = x; } if (x < min){ min = x; } datainput.enqueue(x) //datainput qqueue<double> while (datainput.size() > 60){ datainput.dequeue(); } update(); //this triggers paint event } here graphing function graph function: //this draws min line , max line qpainter painter(this); int linedist = 25; qpen mypen(qt::black, 3); qpoint maxtext(10,20); painter.drawtext(maxtext, "max"); qpoint maxlineleft(0, linedist); qpoint maxlineright(width(), linedist); painter.drawline(maxlineleft, maxlineright); qpoint mintext(10, height()-10); painter.drawtext(mintext, "min"); qpoint minlineleft(0, height()-linedist); qpoint minlineright(width(), height()-linedist); //this draws actual graph mypen.setcolor(qt::blue); mypen.setwidth(2);

we're using compiled expression trees generate code dynamically; information available @ runtime enables (in theory) write simpler, faster code. performance boost in many cases. however, in cases performance hit. in such cases, visual studio profiler shows difference in performance due method (which doesn't show @ in statically compiled code) jit_methodaccesscheck what method do? (google doesn't have it). can optimize away somehow? jit_methodaccesscheck method performs security checks such securitytransparent , aptca , class access checks mentioned @xanatos. class access checks include securitycritical , securitysafecritical , attached profiler bypass , linkdemand . more details can found @ coreclr jithelpers.cpp . since coreclr compatible clr, can safely assume checks in same manner in both of them.

i think "call" instruction kind of "jump" instruction.

we trying create simulation script need send tcp packet data server in way appears coming different ip every time. need emulate multiple devices ( different ip) sending data server. server creates new connection request coming in new ip. best possible way achieve ? there way of using proxy servers or sort of virtualization accomplish ? what want use ip aliasing. allows create virtual network interfaces. each virtual interface can have 1 or more ip addresses assigned it. this link shows how in linux. link shows how in windows. next clients need specify of addresses use. use getifaddrs() enumerate available addresses. use bind() system call on socket before connect() . way can have multiple clients , each 1 use different source ip address. post has details.

is possible ask org mode report list of todo items worked on over period of time? we can assume each todo entry have time tag, e.g. <2014-03-13 thu 17:04> a quick way @ logbook in agenda. you can @ agenda (see agenda views in org mode docs). move agenda time period want - day, week, month, year. put in logbook mode (via 'l' key, described in section 10.5 commands in agenda buffer ). show time period tasks worked on , when. you can use clock table (see section 8.4.2 clock table ) detailed report can set details of interested in. (note: section heading numbers refer in org-mode version 8.2.5h - version may differ, sections still there)

i new vba. have 2 sheets under excel: "data", "sheet1".data sheet amended every day. use vlookup vba macro rows added column in sheet1. code doesn't give me results (it works if run macro under same sheet data are). thank you private sub commandbutton21_click() on error resume next sheet1.range("b3:d500").clear dim dept_row long dim dept_clm long table1 = sheet1.range("a3:a50") table2 = data.range("a3:h24") dept_row = sheet1.range("b3").row dept_clm1 = sheet1.range("b3").column dept_clm2 = sheet1.range("c3").column dept_clm3 = sheet1.range("d3").column each cl in table1 sheet1.cells(dept_row, dept_clm1) = application.worksheetfunction.vlookup(cl, table2, 6, false) sheet1.cells(dept_row, dept_clm2) = application.worksheetfunction.vlookup(cl, table2, 7, false) sheet1.cells(dept_row, dept_clm3) = application.worksheetfunction.vlookup(cl, table2, 8, false) dept_row = dept_row + 1

i have dataframe 10 fields. in 10th field there missing data, , need fill them. so let's row, row-a, have 10th field empty. if there row-b such fields 3 7 row-a , row-b have same values, want copy value @ 10th field of row-b 10th field of row-a. , don't know how it.

i'm trying emulate trustzone features in qemu. i've found 2 links seems explain process. the first reference doesn't attach image kernel supports trustzone (where can find it?) the second reference explains how can compile kernel doesn't start command line written in first website follows ./arm-softmmu/qemu-system-arm -kernel $path_to_kernel/zimage -m vexpress-a15 -cpu cortex-a15 -dtb path_to_dtb/vexpress-v2p-ca15-tc1.dtb -m 1024 -append 'console=ttyama0,38400n8' -serial stdio -initrd $path_to_initrd/initrd.img is there alternate way run trustzone emulator? with op-tee (an open source tee) it's easy run trustzone on qemu. have entire stack running code normal world user space , linux kernel down secure world, running both tee trusted applications. qemu + op-tee works on both armv7-a , armv8-a. if want try out on local pc encourage head on optee_os/readme.md , follow instructions in section 4.1, 5 (only qemu related) , 6. in we're

solution instead of using setinitialrange() had set initial x-values using setxaxismin() setxaxismax() . little bit confusing, think. original question i'm working on project involving acharteninge library drawing time diagrams works excellent far. user capable of switching between various graphs (one xymultipleseriesdataset plus 1 timeseries per graph) via separate buttons. far, achartengine displays x values when graph shown. however, asked display data captured in first 3 hours when graph shown, information relevant. nevertheless, user should still able scroll data captured after first 3 hours meaning limiting x-axis maximum value not option. for example: there 2 curves. first curve drawn using data captured on period of 4 hours, while second curve created out of data captured on 18 hours. in current version programme displays data of graph gets displayed meaning first curve shows 3 hours of relevant data while 1 hour of not important information shown too. &qu
