this code convert 1 hexadecimal digit decimal value. int value; // ch char variable holding hexadecimal digit if (isxdigit(ch)) if (isdigit(ch)) value = ch - '0'; else value = tolower(ch) - 'a' + 10; else fprintf(stderr, "%c not valid hex digit", ch); i don't understand how works though. can see different things subtracted char variable depending on whether number or letter. can understand part number gets converted, don't understand why 10 has added value when character letter. the subtraction of tolower(ch) - 'a' map character number in range 0..5 letters a..f. however, (decimal) value of hexadecimal digit a 16 10 10 , move range 10..15 needs be, 10 added. perhaps helps: +---------+------------+-----------------+-------------+ character | subtracted | resulting value | digit value | +---------+------------+-----------------+-------------+ | '0' | '0' | 0

how these sequence files generated ? saw link sequence file here, http://wiki.apache.org/hadoop/sequencefile are these written using default java serializer ? , how read sequence file ? sequence files generated mapreduce tasks , and can used common format transfer data between mapreduce jobs. you can read them in following manner: configuration config = new configuration(); path path = new path(path_to_your_file); sequencefile.reader reader = new sequencefile.reader(filesystem.get(config), path, config); writablecomparable key = (writablecomparable) reader.getkeyclass().newinstance(); writable value = (writable) reader.getvalueclass().newinstance(); while (reader.next(key, value)) // perform operating reader.close(); also can generate sequence files using sequencefile.writer. the classes used in example following: import org.apache.hadoop.conf.configuration; import org.apache.hadoop.fs.filesystem; import org.apache.hadoop.fs.path; import org.apache.hadoop.

i having bit of trouble retrieving variables asp page. returns entire page whereas need variable stranswer page. please help? here code: var loader:urlloader = new urlloader(); loader.addeventlistener(event.complete, ondatasaved); loader.dataformat = urlloaderdataformat.variables; var request:urlrequest = new urlrequest("http://" + host + urlpath + "setxml.asp"); request.method = urlrequestmethod.post; var variables:urlvariables = new urlvariables(); variables.xmlstring = str; variables.eltguid = eltguid; request.data = variables; loader.load(request); private function ondatasaved(e:event):void { var loader2:urlloader = urlloader(e.target); loader2.dataformat = urlloaderdataformat.variables; trace(loader2.data.stranswer); } asp page: <%@language="vbscript" codepage="65001"%> <% response.cachecontrol = &

so every calendar app out there have ever used lets add events schedule, , see color rectangle shows event title, , sized depending on length. if event runs 1:00-1:45, rectangle takes 3/4 of hour slot. using eventkit, , eventkitui, have realized making events going quite easy, wondering next step, graphically making events visible user. i plan on using simple uitableview day view, when add event, how go representing graphically? looking ideas on implementation here. don't know how this. matter of making custom label , adding top of selected cell? i realizing programming partly problem of knowing how something, , other knowing do. @ point, struggling part, because think if had direction, in code no problem. any ideas? check out. https://github.com/klazuka/kal i played sample code , threw watch on on github because liked did. calendar functions, maybe can ideas flowing.

i've been working on update shopping assistant , shopping list management application , trying create functionality email shopping lists nothing json encoded text files contain shopping list created application different user has application installed. when email received, , 1 tries preview/open attachment, shopping assistant app should presented option open attachment. however, no matter intent filers have tried, doesn't work. can't app called when attachment previewed. true created custom mime type called application/sal (sal extension give file attachment) , added intent filter manifest file looks this: <intent-filter> <action android:name="android.intent.action.action_view" /> <category android:name="android.intent.category.default" /> <data android:mimetype="application/sal" /> </intent-filter> but no success. i've tried use text/xml mime type in

i'm developing web application using simple (maybe not mvc-compliant) mvc framework, coded myself while developing application keep code clean. application, though, has many ajax components , i'm stuck trying integrate them within general mvc structure. how should integrated? i have in javascript files: $('#pagelist').load(base_site_url + 'ajax/pagelist.php'); and pagelist.php used have structure following one: <?php require '../includes/config.inc.php'; require base_path . 'includes/init.inc.php'; // whole load of controller logic here , then... echo "<table>"; //display user data echo "</table>"; i'm confused this, advice appreciated few pointers - website should functional without javascript. example, if have pagination page urls /list/?page=1 ... /list/?page=n should make sure of pages clickable without needing javascript. javascript should extension website. in above example,

i have built package r wraps r around java classes. on development laptop (ubuntu) package loads , works great. on 2 other machines (one ubuntu, 1 debian) have tried use package , classpath not being set .jpackage() call. all 3 machines running r 2.12.1 , rjava .8-8 believe recent. the entire package up @ google code here's contents of zzz.r file works set class path on 1 machine not others: ##' @import rjava .onload <- function(lib, pkg) { pathtosdk <- paste(system.file(package = "gsradr") , "/gsrad_sample/lib/", sep="") jarpaths <- c(paste(pathtosdk, "clima_core-1.0.0.jar", sep=""), paste(pathtosdk, "clima_gsrad-1.0.0.jar", sep=""), paste(pathtosdk, "colt-1.0.jar", sep=""), paste(pathtosdk, "commons-lang-2.0.jar", sep=""), paste(pathtosdk, "junit-3.8.1.jar",

i have general question, may little compiler-specific. i'm interested in conditions under constructor called. specifically, in release mode/builds optimised speed , compiler-generated or empty constructor called when instantiate object? class noconstructor { int member; }; class emptyconstructor { int member; }; class initconstructor { initconstructor() : member(3) {} int member; }; int main(int argc, _tchar* argv[]) { noconstructor* nc = new noconstructor(); //will call generated constructor? emptyconstructor* ec = new emptyconstructor(); //will call empty constructor? initconstructor* ic = new initconstructor(); //this call defined constructor emptyconstructor* ecarray = new emptyconstructor[100]; //is different? } i've done lot of searching, , spent time looking through generated assembly code in visual studio. can difficult follow in release builds though. in summary: constructor

is possible launch kernels different threads of (host) application , have them run concurrently on same gpgpu device? if not, know of plans (of nvidia) provide capability in future? the programming guide http://developer.download.nvidia.com/compute/cuda/3_1/toolkit/docs/nvidia_cuda_c_programmingguide_3.1.pdf says: 3.2.7.3 concurrent kernel execution devices of compute capability 2.0 can execute multiple kernels concurrently. applications may query capability calling cudagetdeviceproperties() , checking concurrentkernels property. maximum number of kernel launches device can execute concurrently sixteen. so answer is: depends. depends on device. host threads won't make difference in way. concurrent kernel launches serialized if device doesn't support concurrent kernel execution , if device does, serial kernel launches on different streams executed concurrently.

i've been racking brain trying figure out little bug in ipad half of app i'm working on. it's related problem in post: ipad splitviewcontroller strange behaviour actually, should it's same problem. however, solution given there won't work me, since app has main menu swaps on uisplitviewcontroller's view when proper button pressed. controller , contained view controllers aren't created until button press. thus, can't set controller's delegate before calling [window makekeyandvisible], since that's done way when main menu loads. now, i've added nslog calls delegate's willhideviewcontroller function follows: nslog(@"will hide popover view controller!"); nslog(@"self=%p",self); nslog(@"%@",detailpad.tbtoolbar); when start app on ipad in portrait mode, , click switch on split view controller, delegate's willhideviewcontroller indeed called, when finishes, i'm left empty toolbar in detail vi
