  • Question about effective logging in C#

    - by MartyIX
    I've written a simple class for debugging and I call the method Debugger.WriteLine(...) in my code like this: Debugger.WriteLine("[Draw]", "InProgress", "[x,y] = " + x.ToString("0.00") + ", " + y.ToString("0.00") + "; pos = " + lastPosX.ToString() + "x" + lastPosY.ToString() + " -> " + posX.ToString() + "x" + posY.ToString() + "; SS = " + squareSize.ToString() + "; MST = " + startTime.ToString("0.000") + "; Time = " + time.ToString() + phase.ToString(".0000") + "; progress = " + progress.ToString("0.000") + "; step = " + step.ToString() + "; TimeMovementEnd = " + UI.MovementEndTime.ToString()); The body of the procedure Debugger.WriteLine is compiled only in Debug mode (directives #if, #endif). What makes me worry is that I often need ToString() in Debugger.WriteLine call which is costly because it creates still new strings (for changing number for example). How to solve this problem? A few points/questions about debugging/tracing: I don't want to wrap every Debugger.WriteLine in an IF statement or to use preprocessor directives in order to leave out debugging methods because it would inevitable lead to a not very readable code and it requires too much typing. I don't want to use any framework for tracing/debugging. I want to try to program it myself. Are Trace methods (http://msdn.microsoft.com/en-us/library/system.diagnostics.trace.aspx) left out if compiling in release mode? If it is so is it possible that my methods would behave similarly? http://msdn.microsoft.com/en-us/library/fht0f5be.aspx output = String.Format("You are now {0} years old.", years); Which seems nice. Is it a solution for my problem with ToString()?

  • Hardware Pen device for presentation

    - by sankar
    Hi I have a scenario. Hope you could suggest the software and hardware required? I teach maths. I write math equations as i do in a paper/ohp and this should get displayed on the screen. I find hardware 'pen' - writing and pointing device. Tablet pen- I accept my limited knowledge on that. Here is how I conceive it could be done? I need you to correct my understanding and shed light anyother better method? tablet pen - plate (on which i write) - ms-powerpoint pen option - empty slide Is it possible to save the such content for reproduction. regds, sankar

  • What's the difference between hardware and software interrupt?

    - by robotrobert
    I'm gonna sketch my understanding of both. I've googled around but i'm not sure about my knowledge. Please correct me! Hardware interrupt is generated by the operation system event scheduler to reassign the cpu time for another process. Is this true? Software interrupt can be generated from a running program who wants for example to read a file, and for that we need to reassign the cpu for the appropriate operation system call. Is this true? Is there other kind of software/hardware interrupts?

  • How to make ssh/rsync/etc use a VLAN network interface?

    - by Annan
    A company I work for has a number of virtual servers with ElasticHosts. They are setup in such a way that eth1 is on a private VLAN connecting them to each other. This is so backups sent between servers are not charged at the same rate as external data transfer. My understanding of how VLANs and network interfaces work is sketchy at best. How can I make ssh, rsync, etc. transfer data through the VLAN? My final solution: I spent a while trying to figure this out, For all servers involved, edit /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 BOOTPROTO=static ONBOOT=yes HWADDR=YOUR_MAC_ADDR IPADDR=192.168.0.100 NETMASK=255.255.255.0 Where HWADDR should already be set and the last octate of IPADDR should be different from each other. Then run, on all servers /etc/init.d/network restart After this the IP addresses specified by IPADDR can be used directly as any other IP address.

  • clojure.algo.monad strange m-plus behaviour with parser-m - why is second m-plus evaluated?

    - by Mark Fisher
    I'm getting unexpected behaviour in some monads I'm writing. I've created a parser-m monad with (def parser-m (state-t maybe-m)) which is pretty much the example given everywhere (here, here and here) I'm using m-plus to act a kind of fall-through query mechanism, in my case, it first reads values from a cache (database), if that returns nil, the next method is to read from "live" (a REST call). However, the second value in the m-plus list is always called, even though its value is disgarded (if the cache hit was good) and the final return is that of the first monadic function. Here's a cutdown version of the issue i'm seeing, and some solutions I found, but I don't know why. My questions are: Is this expected behaviour or a bug in m-plus? i.e. will the 2nd method in a m-plus list always be evaluated if the first item returns a value? Minor in comparison to the above, but if i remove the call _ (fetch-state) from checker, when i evaluate that method, it prints out the messages for the functions the m-plus is calling (when i don't think it should). Is this also a bug? Here's a cut-down version of the code in question highlighting the problem. It simply checks key/value pairs passed in are same as the initial state values, and updates the state to mark what it actually ran. (ns monods.monad-test (:require [clojure.algo.monads :refer :all])) (def parser-m (state-t maybe-m)) (defn check-k-v [k v] (println "calling with k,v:" k v) (domonad parser-m [kv (fetch-val k) _ (do (println "k v kv (= kv v)" k v kv (= kv v)) (m-result 0)) :when (= kv v) _ (do (println "passed") (m-result 0)) _ (update-val :ran #(conj % (str "[" k " = " v "]"))) ] [k v])) (defn filler [] (println "filler called") (domonad parser-m [_ (fetch-state) _ (do (println "filling") (m-result 0)) :when nil] nil)) (def checker (domonad parser-m [_ (fetch-state) result (m-plus ;; (filler) ;; intitially commented out deliberately (check-k-v :a 1) (check-k-v :b 2) (check-k-v :c 3))] result)) (checker {:a 1 :b 2 :c 3 :ran []}) When I run this as is, the output is: > (checker {:a 1 :b 2 :c 3 :ran []}) calling with k,v: :a 1 calling with k,v: :b 2 calling with k,v: :c 3 k v kv (= kv v) :a 1 1 true passed k v kv (= kv v) :b 2 2 true passed [[:a 1] {:a 1, :b 2, :c 3, :ran ["[:a = 1]"]}] I don't expect the line k v kv (= kv v) :b 2 2 true to show at all. The first function to m-plus (as seen in the final output) is what is returned from it. Now, I've found if I pass a filler into m-plus that does nothing (i.e. uncomment the (filler) line) then the output is correct, the :b value isn't evaluated. If I don't have the filler method, and make the first method test fail (i.e. change it to (check-k-v :a 2) then again everything is good, I don't get a call to check :c, only a and b are tested. From my understanding of what the state-t maybe-m transformation is giving me, then the m-plus function should look like: (defn m-plus [left right] (fn [state] (if-let [result (left state)] result (right state)))) which would mean that right isn't called unless left returns nil/false. I'd be interested to know if my understanding is correct or not, and why I have to put the filler method in to stop the extra evaluation (whose effects I don't want to happen). Apologies for the long winded post!

  • Compiled Haskell libraries with FFI imports are invalid when imported into GHCI

    - by John Millikin
    I am using GHC 6.12.1, in Ubuntu 10.04 When I try to use the FFI syntax for static storage, only modules running in interpreted mode (ie GHCI) work properly. Compiled modules have invalid pointers, and do not work. I'd like to know whether anybody can reproduce the problem, whether this an error in my code or GHC, and (if the latter) whether it's a known issue. I'm using sys_siglist because it's present in a standard library on my system, but I don't believe the actual storage used matters (I discovered this while writing a binding to libidn). If it helps, sys_siglist is defined in <signal.h> as: extern __const char *__const sys_siglist[_NSIG]; I thought this type might be the problem, so I also tried wrapping it in a plain C procedure: #include<stdio.h> const char **test_ffi_import() { printf("C think sys_siglist = %X\n", sys_siglist); return sys_siglist; } However, importing that doesn't change the result, and the printf() call prints the same pointer value as show siglist_a. My suspicion is that it's something to do with static and dynamic library loading. Update: somebody in #haskell suggested this might be 64-bit specific; if anybody tries to reproduce it, can you mention your architecture and whether it worked in a comment? Code as follows: -- A.hs {-# LANGUAGE ForeignFunctionInterface #-} module A where import Foreign import Foreign.C foreign import ccall "&sys_siglist" siglist_a :: Ptr CString -- -- B.hs {-# LANGUAGE ForeignFunctionInterface #-} module B where import Foreign import Foreign.C foreign import ccall "&sys_siglist" siglist_b :: Ptr CString -- -- Main.hs {-# LANGUAGE ForeignFunctionInterface #-} module Main where import Foreign import Foreign.C import A import B foreign import ccall "&sys_siglist" siglist_main :: Ptr CString main = do putStrLn $ "siglist_a = " ++ show siglist_a putStrLn $ "siglist_b = " ++ show siglist_b putStrLn $ "siglist_main = " ++ show siglist_main peekSiglist "a " siglist_a peekSiglist "b " siglist_b peekSiglist "main" siglist_main peekSiglist name siglist = do ptr <- peekElemOff siglist 2 str <- maybePeek peekCString ptr putStrLn $ "siglist_" ++ name ++ "[2] = " ++ show str I would expect something like this output, where all pointer values identical and valid: $ runhaskell Main.hs siglist_a = 0x00007f53a948fe00 siglist_b = 0x00007f53a948fe00 siglist_main = 0x00007f53a948fe00 siglist_a [2] = Just "Interrupt" siglist_b [2] = Just "Interrupt" siglist_main[2] = Just "Interrupt" However, if I compile A.hs (with ghc -c A.hs), then the output changes to: $ runhaskell Main.hs siglist_a = 0x0000000040378918 siglist_b = 0x00007fe7c029ce00 siglist_main = 0x00007fe7c029ce00 siglist_a [2] = Nothing siglist_b [2] = Just "Interrupt" siglist_main[2] = Just "Interrupt"

  • multiple domains, one static IP address and latency

    - by shirish
    how is latency affected when multiple domains are using one single static IP address ? The scenario is in shared web-hosting By latency meaning the DNS lookup the client has to do. As far as I understand it, the browser would hit the root servers to try to figure out the IP Address and it belongs where and then when it comes to the correct server, it probably looks up some sort of table to determine which site names much and show that site as such via browser to the user. Is my understanding correct or backwards or what ?

  • Parsing xml with php and xpath

    - by Hyung Suh
    Hey guys, I'm trying to parse an xml file to return a item with a specific id only, but having trouble making it work. here's what I have in php $xml_str = file_get_contents("test.xml"); $xml = simplexml_load_string($xml_str); $albid = $_GET['id']; $nodes = $xml->xpath('//library/book[@id=1]'); foreach($nodes as $node) { echo $node['title'].'<br/>'; } First, the php is not returning anything from the xml file. What would I need to fix to return the data? Also, how would I enter $albid into the xpath so that the id will be retrieved from the link? Any pointers in the right direction would be appreciated. Thanks! --and here's the sample xml file-- <library> <book id="1"> <title>PHP and MySQL</title> <author fname="miguel" lname="alvarez">Miguel Alvarez</author> </book> <book id="2"> <title>JAVA 123</title> <author fname="william" lname="vega">WIlliam Vega</author> </book>

  • Having vCam on custom classes instead of the root class.

    - by Hwang
    Maybe some of you guys know bout vCam from http://bryanheisey.com/blog/?page_id=22 I'm trying to have the script running on a custom classes instead of a MovieClip in the library. But after some trying I fail so I stick back to having the MC in the library and load the MC from the project root action-script files. Now it works fine if I run the MC on the root as files, but for more organizing purposes on my action-script files, I was thinking of calling it from a custom classes(where I can control the vCam), then call the custom classes from the root action-script files. But seems like it won't work other than the root action-script files. I'm not sure whether I'm missing any codes between the two custom classes, or its not coded to run that way. If it's not, then its fine too just that I want the things more organize. Or if you have any idea how to 'by-pass' this, please do tell me so. In case you need my code for the 2 classes, here it is: package { import flash.display.MovieClip; import classes.vCamera; public class main extends MovieClip { private var vC2:vCamera = new vCamera(); public function main():void { addChild(vC2) } } } package classes{ import flash.display.MovieClip; import flash.display.Stage; import flash.events.Event; public class vCamera extends MovieClip{ private var vC:vCam = new vCam(); public function vCamera():void{ addEventListener(Event.ADDED_TO_STAGE, add2Stage) } private function add2Stage(event:Event):void{ vC.x=stage.stageWidth/2; vC.y=stage.stageHeight/2; vC.rotation=15; addChild(vC); } } }

  • Browsing Pictures on a Mac

    - by Mr Woody
    Hi. After many years using linux, I decided to buy a mac. Now my main problem is: how do I synchronize pictures within my linux machines and the mac? I have been using digikam in linux, and I like it because I can just browse the pictures directly from my directories (and it is easy for me to keep directories synchronized within mac and linux). I have been testing iphoto and aperture, which are quite nice but if use them, my understanding is that I have to import all the pictures into these softwares, and this doesn't seem to be the ideal solution for me. I tried picasa, but I don't find it as good as iphoto and aperture. On the other hand it allows me to browse directories, without having two copies of the same pictures. I didn't try lightroom yet, would that be a good solution? I would appreciate any suggestion on this. Thanks!

  • Why does the EFI shell not detect my Windows DVD?

    - by Oliver Salzburg
    I'm currently looking into (U)EFI for the first time and am already really confused. I insert the Windows Server 2008 R2 Enterprise disc into the DVD-ROM and boot into the EFI shell. The shell will automatically list all detected devices, which are: blk0 :CDRom - Alias (null) Acpi(PNP0A03,0)/Pci(1F|2)/Ata(Primary,Master)/CDROM(Entry0) blk1 :BlockDevice - Alias (null) Acpi(PNP0A03,0)/Pci(1F|2)/Ata(Primary,Master) To my understanding, it should have already detected the filesystem on blk0 and should have mounted it as fs0. Why is that not happening? If I insert a USB drive, it gets mounted just fine. The board is an Intel S5520HC in case that makes a difference.

  • Xen private networking between multiple hosts

    - by Joe
    I have two physical hosts running Xen 3.2, sharing storage via iSCSI. On these two hosts are a number of domUs and I'd like to network them in multiple private networks so they can only contact other domUs on their private network. My understanding of the xen documentation suggests it's possible to do this within one dom0 (ie create virtual networks between domUs), but I've found nothing explaining how this can be implemented across multiple dom0s on different hosts. The only thing that jumps to mind is manually creating iptable rules to route data to the other host, but this seems to lack elegance and could quickly grow cumbersome. Any suggestions? All advice is much appreciated!

  • Any program or editor in windows 7 to run ".md" files

    - by Anmol Saraf
    I understand that '.md' is an extension for markdown format. While installing 'Grunt' from GitHub I see a lot of .md extension files inside node_module/grunt/docs folder. As per my understanding these files are supported by GitHub for documentation kind of things if I am not wrong. My question here is - Are there any editors/tools or programs available for Windows 7 where I can see these .md files executing ? When I try to open any of these file inside my text editor it displays in raw format with all '#" etc. keywords. I want to see the formatted version of these files so that without an internet connection also I can navigate the documentation on my machine. Thanks for helping !!

  • How is it possible that Winrar can repair any volume with one .rev file?

    - by Coldblackice
    I just learned about .rev files with Winrar -- that if you have a 10-part RAR volume, for example, plus one .rev (recovery) volume -- that .rev volume will be able to "fix" any -one- corrupted volume. How is it able to do this? Obviously there's something I'm not understanding, as I don't understand how one volume could have the "data" to fix any/all of the individual broken volumes. I'd guess that it's because the volumes aren't broken up like I tend to imagine -- each volume having individual files of the whole packed into them, but rather, it's viewed as one continuous "file", so to speak, of data. And that there must be some type of CRC'ish repair work -- But I just don't understand how you could have 9 working volumes, with 1 damaged, but a recovery volume that would be able to repair -any- one of those volumes. How is it able to hold "all" of the data in just one recovery file?

  • mod_proxy failing as forward proxy in simple configuration

    - by Stabledog
    (On Mac OS X 10.6, Apache 2.2.11) Following the oft-repeated googled advice, I've set up mod_proxy on my Mac to act as a forward proxy for http requests. My httpd.conf contains this: <IfModule mod_proxy> ProxyRequests On ProxyVia On <Proxy *> Allow from all </Proxy> (Yes, I realize that's not ideal, but I'm behind a firewall trying to figure out why the thing doesn't work at all) So, when I point my browser's proxy settings to the local server (ip_address:80), here's what happens: I browse to http://www.cnn.com I see via sniffer that this is sent to Apache on the Mac Apache responds with its default home page ("It works!" is all this page says) So... Apache is not doing as expected -- it is not forwarding my browser's request out onto the Internet to cnn. Nothing in the logfile indicates an error or problem, and Apache returns a 200 header to the browser. Clearly there is some very basic configuration step I'm not understanding... but what?

  • Logging off does not kill process in Windows Server 2003

    - by Suraj Chandran
    I have a Windows Server 2003(Enterprise, SP2). My understanding was that any process created by a user will be terminated when the user loggs off the account. But its not happening. I login via Administrator account. Start a simple java process and logoff. But the process is not killed. Is there any configuration for this or something? I am mostly a software programmer and not much in to servers and so I am stuck. I found out that while logging off, 1) Win32 is supposed to send a CTRL_LOGOFF_EVENT to all processes started by that user. 2) JVM is supposed to handle this event and terminate the VM. But I can't understand why my java process is not killed when i logoff. Any idea!!!

  • Is any EXIF data stored within 3rd party Camera apps on the iPhone?

    - by 3rdparty
    I'm confused as to if any EXIF data is available when taking photos within 3rd party camera apps on the iPhone. My understanding is that Apple is currently not allowing any apps to save EXIF data to photos, and this is a limitation of saving to the camera roll on the phone. The last FAQ on this page indicates this, but appears to be out of date: http://www.codegoo.com/page/support I love some of the camera apps I've downloaded (Camera Genius, Best Camera, CameraBag) but don't want to continue using them if they aren't saving any/all EXIF data for the image. Anyone aware what the status of this 'limitation' is?

  • Unit testing opaque structure based C API

    - by Nicolas Goy
    I have a library I wrote with API based on opaque structures. Using opaque structures has a lot of benefits and I am very happy with it. Now that my API are stable in term of specifications, I'd like to write a complete battery of unit test to ensure a solid base before releasing it. My concern is simple, how do you unit test API based on opaque structures where the main goal is to hide the internal logic? For example, let's take a very simple object, an array with a very simple test: WSArray a = WSArrayCreate(); int foo = 5; WSArrayAppendValue(a, &foo); int *bar = WSArrayGetValueAtIndex(a, 0); if(&foo != bar) printf("Eroneous value returned\n"); else printf("Good value returned\n"); WSRelease(a); Of course, this tests some facts, like the array actually acts as wanted with 1 value, but when I write unit tests, at least in C, I usualy compare the memory footprint of my datastructures with a known state. In my example, I don't know if some internal state of the array is broken. How would you handle that? I'd really like to avoid adding codes in the implementation files only for unit testings, I really emphasis loose coupling of modules, and injecting unit tests into the implementation would seem rather invasive to me. My first thought was to include the implementation file into my unit test, linking my unit test statically to my library. For example: #include <WS/WS.h> #include <WS/Collection/Array.c> static void TestArray(void) { WSArray a = WSArrayCreate(); /* Structure members are available because we included Array.c */ printf("%d\n", a->count); } Is that a good idea? Of course, the unit tests won't benefit from encapsulation, but they are here to ensure it's actually working.

  • How do I merge multiple PDB files ?

    - by blue.tuxedo
    We are currently using a single command line tool to build our product on both Windows and Linux. Si far its works nicely, allowing us to build out of source and with finer dependencies than what any of our previous build system allowed. This buys us great incremental and parallel build capabilities. To describe shortly the build process, we get the usual: .cpp -- cl.exe --> .obj and .pdb multiple .obj and .pdb -- cl.exe --> single .dll .lib .pdb multiple .obj and .pdb -- cl.exe --> single .exe .pdb The msvc C/C++ compiler supports it adequately. Recently the need to build a few static libraries emerged. From what we gathered, the process to build a static library is: multiple .cpp -- cl.exe --> multiple .obj and a single .pdb multiple .obj -- lib.exe --> a single .lib The single .pdb means that cl.exe should only be executed once for all the .cpp sources. This single execution means that we can't parallelize the build for this static library. This is really unfortunate. We investigated a bit further and according to the documentation (and the available command line options): cl.exe does not know how to build static libraries lib.exe does not know how to build .pdb files Does anybody know a way to merge multiple PDB files ? Are we doomed to have slow builds for static libraries ? How do tools like Incredibuild work around this issue ?

  • What are the things to look out for when adding other domain user to your IIS?

    - by Jack
    I have a Windows Server 2008 R2 called Jack11 that joined a domain called Watson.org. It has IIS 7 installed. From my understanding, we need to add the following into the web.config file <system.web> <identity impersonate="true" /> </system.web> Also, we need to ensure that the server Jack11 can ping to the domain Watson.org. What other setting do we need to setup in order for a user of domain Watson.org (e.g. the user Watson\User1 to access the application in the Server IIS? This is because currently, there is a problem as follows: Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'WATSON\User1'. The error message was displayed when the user User1 wish to access one of the web application in server Jack11 IIS and that web application also do some retrieval of records from the database, which is installed in SQL Server 2008 Enterprise located in the same server Jack11.

  • How to- NSAttributedString to CGImageRef

    - by kroko
    Hello! I'm writing a QuickLook plugin. Well, everything works. Just want to try it make better ;). Thus the question. Here is a function that returns thumbnail image and that I'm using now. QLThumbnailRequestSetImageWithData( QLThumbnailRequestRef thumbnail, CFDataRef data, CFDictionaryRef properties); ); http://developer.apple.com/mac/library/documentation/UserExperience/Reference/QLThumbnailRequest_Ref/Reference/reference.html#//apple_ref/c/func/QLThumbnailRequestSetImageWithData Right now I'm creating a TIFF - encapsulated it into NSData. An example // Setting CFDataRef CGSize thumbnailMaxSize = QLThumbnailRequestGetMaximumSize(thumbnail); NSMutableAttributedString *attributedString = [[[NSMutableAttributedString alloc] initWithString:@"dummy" attributes:[NSDictionary dictionaryWithObjectsAndKeys: [NSFont fontWithName:@"Monaco" size:10], NSFontAttributeName, [NSColor colorWithCalibratedRed:0.0 green:0.0 blue:0.0 alpha:1.0], NSForegroundColorAttributeName, nil] ] autorelease]; NSImage *thumbnailImage = [[[NSImage alloc] initWithSize:NSMakeSize(thumbnailMaxSize.width, thumbnailMaxSize.height)] autorelease]; [thumbnailImage lockFocus]; [[NSColor whiteColor] set]; NSRectFill(NSMakeRect(0, 0, thumbnailMaxSize.width, thumbnailMaxSize.height)); [attributedString drawInRect:NSMakeRect(0, 0, thumbnailMaxSize.width, thumbnailMaxSize.height)]; [thumbnailImage unlockFocus]; (CFDataRef)[thumbnailImage TIFFRepresentation]; // This is data // Setting CFDictionaryRef (CFDictionaryRef)[NSDictionary dictionaryWithObjectsAndKeys:@"kUTTypeTIFF", (NSString *)kCGImageSourceTypeIdentifierHint, nil ]; // this is properties However QuickLook provides another function to return thumbnail image, namely QLThumbnailRequestSetImage( QLThumbnailRequestRef thumbnail, CGImageRef image, CFDictionaryRef properties); ); http://developer.apple.com/mac/library/documentation/UserExperience/Reference/QLThumbnailRequest_Ref/Reference/reference.html#//apple_ref/c/func/QLThumbnailRequestSetImage I have a feeling that passing CGImage to the QL instead of TIFF data would help in speeding things up. However- I have never worked with CG context before. I know, the documentation is there :), but anyways- could anyone give an example how to turn that NSAttributed string into CGImageRef. An example is worth 10 times reading the documentation ;) Any help appreciated. Thanks in advance!
