i wanting use visual studio's graphics diagnostics debug shader code, when try "start diagnostics", immediate access violation in dxgi.dll. access violation appears occur before program's main function entered. tried adding sleep inside winmain function attach separate debugger, code never hit. opened 1 of directx sdk sample programs same installation of vs2013 , graphics diagnostics worked fine. tried using graphics diagnostics on program on 2 separate pcs , both threw same access violation. i suspect maybe has project configuration? seems failing establish connection between graphics diagnostics debugger , program before entry point of program called. any ideas appreciated!

is there way know if has uploaded generated public presigned url of s3? callback trigger servlet. for example: i created presigned url docs amazons3 s3client = new amazons3client(new profilecredentialsprovider()); java.util.date expiration = new java.util.date(); long msec = expiration.gettime(); msec += 1000 * 60 * 60; // add 1 hour. expiration.settime(msec); generatepresignedurlrequest generatepresignedurlrequest = new generatepresignedurlrequest(bucketname, objectkey); generatepresignedurlrequest.setmethod(httpmethod.put); generatepresignedurlrequest.setexpiration(expiration); url url = s3client.generatepresignedurl(generatepresignedurlrequest); // use pre-signed url upload object. then, give url , if upload url , http://example.com/upload invoked data uploaded file. you can use s3 event notifications generate notification. @ objectcreated event. notifications can filtered s3 prefix.

i have hp procurve switch, added 2 new machines network, had assign ip addresses manually. using these 2 machines can ping current machine , other machines on network, if try ping 2 machines current machine (or others on network) not go through. thoughts router table has not updated that's why can't ping them machines have been on router. (not sure, not enough knowledge yet) at least think so. question router table update it's information automatically? assuming hp procurve acting switch, routing table should not problem. switch not route ips, switch concerned routing packets via layer-2 addresses (mac addresses). switch determined physical port connected device mac address, , when gets packet addressed mac address, sends packet out port. mapping on port destination mac address stored in cam table inside switch. different routing table maps ip address ranges physical interfaces. what happening arp not resolving. arp binds layer 3 ips layer 2 macs in local

i know dynamic recompilation can used translate instructions 1 architecture during execution. can used optimize program on same architecture? if write poorly optimized assembly language program, can use dynamic recompiler make run faster native speeds? it's impossible create code runs faster native speed, fastest code possible still runs @ native speed only. :) if mean "faster original code", yes, it's possible create tool such purpose, quite difficult make practical , successful. reasoning: with native-compiled languages c++, compiling original source compiler has many strong hints original intent of programmer, , optimizer can more aggressive, not blindly translating char char machine code, producing code holds language definition (ie. omitting whole function call, when result not used, , there's no side effect of function execution). once try optimize native machine code only, wouldn't have additional context. new optimized code must mi

i have query gets executed on sqlite database table wpf application; query can return large amount of records (from 80000 1 million) down-sample before displaying it. takes 10 seconds return 700000 records, can optimized in way? the clause filters records date time column: (where collectedon > @starttime , collectedon < @endtime) and i'm selecting of 18 columns of table. number of columns influence executing time of query? thanks comments. should point out few more things: the data collect needs displayed in chart; since want display 600 points algorithm picks 1 point every 600 700000 records. can achieved in single query? these of things consider: further narrowing down number of returned records (you said down-sample before displaying... can down-sample within database or clause)? do need records @ once? maybe paging (see limit , offset ) you try use index speed query. use explain find out query exactly... afterwards can optimize joins , selecti

i understand use when need give pointer array of pointers in dynamic memory don't understand how works in stack. does make array of pointers in stack pointing array of pointers in heap or make single pointer in stack pointing array of pointers in heap? if yes, difference between int **p = new int*[100] and int *p = new int[100] thanks in advance. have been trying understand long time , have read lot of documentation online still don't understand this. int **p declares pointer on stack points pointer(s) on heap. each of pointer(s) point integer or array of integers on heap. this: int **p = new int*[100]; means declared pointer on stack , initialized points array of 100 pointers on heap. each of 100 pointers point nowhere. "nowhere" mean point neither valid chunk of memory, nor nullptr s. not initialized, contain garbage value in memory before pointers allocated. should assign sensible them in loop before usage. note p[0] - p[99] pointers
