• Java generics SuppressWarnings("unchecked") mystery

  - by Johannes Ernst

  Why does code alternative(1) compile without warnings, and code alternative(2) produce an "unchecked cast" warning?

• Optimize code performance when odd/even threads are doing different things in CUDA

  - by Orion Nebula

  Hi all! I have two large vectors, I am trying to do some sort of element multiplication, where an even-numbered element in the first vector is multiplied by the next odd-numbered element in the second vector .... and where the odd-numbered element in the first vector is multiplied by the preceding even-numbered element in the second vector Ex. vector 1 is V1(1) V1(2) V1(3) V1(4) vector 2 is V2(1) V2(2) V2(3) V2(4) V1(1) * V2(2) V1(3) * V2(4) V1(2) * V2(1) V1(4) * V2(3) I have written a Cuda code to do this: (Pds has the elements of the first vector in shared memory, Nds the second Vector) //instead of using %2 .. i check for the first bit to decide if number is odd/even -- faster if ((tx & 0x0001) == 0x0000) Nds[tx+1] = Pds[tx] * Nds[tx+1]; else Nds[tx-1] = Pds[tx] * Nds[tx-1]; __syncthreads(); Is there anyway to further accelerate this code or avoid divergence ? Thanks

• How to read a file byte by byte in Python and how to print a bytelist as a binary?

  - by zaplec

  Hi, I'm trying to read a file byte by byte, but I'm not sure how to do that. I'm trying to do it like that: file = open(filename, 'rb') while 1: byte = file.read(8) # Do something... So does that make the variable byte to contain 8 next bits at the beginning of every loop? It doesn't matter what those bytes really are. The only thing that matters is that I need to read a file in 8-bit stacks. EDIT: Also I collect those bytes in a list and I would like to print them so that they don't print out as ASCII characters, but as raw bytes i.e. when I print that bytelist it gives the result as ['10010101', '00011100', .... ]

• How to trace a raw (character) device stream on Unix ?

  - by Fabien

  I'm trying to trace what is transiting in a raw (character) device on an Unix system (ex: /dev/tty.baseband) for DEBUG purpose. I am thinking of creating a deamon that would: upon start rename /dev/tty.baseband to /dev/tty.baseband.old. create a raw node /dev/tty.baseband spawn two threads: Thread 1: reading /dev/tty.baseband.old writing into /dev/tty.baseband Thread 2: reading /dev/tty.baseband writing into /dev/tty.baseband.old This would work a little bit like a MITM process. I wonder if there is not a 'standard' way to do this.

• Are we asking too much of transactional memory?

  - by Carl Seleborg

  I've been reading up a lot about transactional memory lately. There is a bit of hype around TM, so a lot of people are enthusiastic about it, and it does provide solutions for painful problems with locking, but you regularly also see complaints: You can't do I/O You have to write your atomic sections so they can run several times (be careful with your local variables!) Software transactional memory offers poor performance [Insert your pet peeve here] I understand these concerns: more often than not, you find articles about STMs that only run on some particular hardware that supports some really nifty atomic operation (like LL/SC), or it has to be supported by some imaginary compiler, or it requires that all accesses to memory be transactional, it introduces type constraints monad-style, etc. And above all: these are real problems. This has lead me to ask myself: what speaks against local use of transactional memory as a replacement for locks? Would this already bring enough value, or must transactional memory be used all over the place if used at all?

• Memory footprint of a parsed XML file in Classic ASP?

  - by Pete Duncanson

  Anyone know of a way to find out the amount of memory/size of a XMLDocument once it has parsed a XML file? I've been doing "beer mat" calculations so far but have been asked to come up with some more legit numbers through monitoring some how. I need to create about 1500 XML files (via FreeThreadedXMl-DOM object), which verge between 3-9K in size and store them in Application vars but our SysAdmin is worried about us gobbling up too much memory. Other than the crude method of booting up a fresh IIS instance and then loading everything in and monitoring before and after memory usage in Task Manager I can't think of a way of doing it with a bit more accuracy.

• In LaTeX prefer figures on text-heavy pages.

  - by bjarkef

  Hi LaTeX seems to have a preference for placing figures together on a page, and placing surrounding text on a separate page. Can I somehow change that balance a bit, as I prefer figures to break up the text to avoid too black text-heavy pages. Example: \section{Some section} [Half a page of text] \begin{figure} [...] \caption{Figure text 1} \end{figure} [Half a page of text] \begin{figure} [...] \caption{Figure text 2} \end{figure} [More text] So what LaTeX usually does is to stack the two half pages of text on a single page, and the figures on the following page. I believe this really gives a bad balance, and bores the reader. So can I change that somehow? I know about postfixing the \begin{figure} with [ht!], but often it does not really matter. I would like to configure the balancing algorithms in LaTeX to naturally prefer pages with combined figures and text.

• How can Request Validation be disabled for HttpHandlers?

  - by Mun

  Is it possible to disable request validation for HttpHandlers? A bit of background - I've got an ASP.NET web application using an HttpHandler to receive the payment response from WorldPay. The IIS logs show that the handler is being called correctly from WorldPay, but the code inside the handler is never called. If I create a physical ASPX page and set ValidateRequest=false in the header, and put the same code in the Page_Load method, the code is called without any problems. This solves the problem, though I'd prefer to stick with using an HttpHandler for this as it's better suited for this type of functionality, rather than having an empty ASPX page, though this is dependent on being able to disable request validation. The web application is using ASP.NET 2.0 and the server is IIS6.

• Filtering A MySQL Result Set Based On The Return Value Of A Function

  - by Joshua

  I'm a SQL noob, and I need a little bit of help understanding the big picture of if it is possible, and if so how to go about filtering a result set based on the return value of a function which is passed one of the fields of the record. Let's say I have a table called "Numbers" with just one field: "Value". How could I correctly specify the following "pseudo-sql"?: SELECT Value FROM numbers WHERE IsPrime(Value)=true Can I accomplish such a thing, and if so, where/how do I put/store "IsPrime"? I'm using MySQL.

• Activator.CreateInstance fails in Windows Service

  - by kbe

  I have an issue with a Windows Service which throws a NullReference exception whenever I try to use var myType = Activator.CreateInstance(typeof(MyType)) There is no problem whenever I run the exact same code in a console window - and after debugging the obvious "which user is running this code" I doubt that it is a mere fact of changing the user running the service as I've tried to run the service using the computer's Administrator account as well as LocalSystem. I'm suspecting a Windows Update fiddling with default user rights but that's a bit of a desperate guess I feel. Remember: The type and assembly exist and works fine - otherwise I wouldn't be able to run the code in a console window. It is only when running in the context of a Windows Service I get an error. The question is: Can I in any way impersonate i.e. LocalSystem in a unittest by creating a GenericPrincipal (how would that GenericPrincipal look)?

But please kindly help if you could.

• Talking to an Authentication Server

  - by Kyle Terry

  I'm building my startup and I'm thinking ahead for shared use of services. So far I want to allow people who have a user account on one app to be able to use the same user account on another app. This means I will have to build an authentication server. I would like some opinions on how to allow an app to talk to the authentication server. Should I use curl? Should I use Python's http libs? All the code will be in Python. All it's going to do is ask the authentication server if the person is allowed to use that app and the auth server will return a JSON user object. All authorization (roles and resources) will be app independent, so this app will not have to handle that. Sorry if this seems a bit newbish; this is the first time I have separated authentication from the actual application.

• count of distinct acyclic paths from A[a,b] to A[c,d]?

  - by Sorush Rabiee

  I'm writing a sokoban solver for fun and practice, it uses a simple algorithm (something like BFS with a bit of difference). now i want to estimate its running time ( O and omega). but need to know how to calculate count of acyclic paths from a vertex to another in a network. actually I want an expression that calculates count of valid paths, between two vertices of a m*n matrix of vertices. a valid path: visits each vertex 0 or one times. have no circuits for example this is a valid path: but this is not: What is needed is a method to find count of all acyclic paths between the two vertices a and b. comments on solving methods and tricks are welcomed.

• Problems with ASP.NET State Service version; state service is 1.1, website is 3.5

  - by Mick Byrne

  Hi there, I have a ASP.NET 3.5 website running on Windows Server 2003 and I'm using the ASP.NET State Service to manage sessions. It will appear to be working then I regularly get an error saying my code needs to have version 2.0 of the State Service running to work (I think that's what it said, I've temporarily switched back to storing sessions InProc). Refresh the page and the error goes away (for a bit, it's bound to come back). So I looked at the properties of the ASP.NET State Service in the Services interface and it's mapping to a .exe in the 1.1 framework folder: C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_state.exe There's a corresponding version in the 2.0 framework folder, but I don't know how to add it as a new service. I'm also not sure that adding the 2.0 version (and stopping and/or removing the 1.1 version) will solve the problem. Thanks in advance for any help anyone can provide. Mick

• How to handle multiple delegates

  - by mac_55

  I've got a view in my app that does pretty much everything, and I like it that way. The problem however is that it's implementing 5 or 6 different delegates, which seems a little bit messy. My question is, does the view controller have to implement all of the delegates? or is there some way I can separate the code out into different files (without having to do a major restructure or rewrite)? Here's all the delegates I'm implementing: @interface MyView : UIViewController <UIScrollViewDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate, UIActionSheetDelegate, MFMailComposeViewControllerDelegate>

• Why is my ipad's wireless so flakey?

  - by Mark

  I'm the proud owner of a new IPad here in the UK. All is good, except for the wifi, which is a bit flakey. It connects fine to my Draytek router which is set for WPA/WPA2 and 56g only, displaying full signal strength. Then, after a few minutes, it goes down to minimum strength... And sometimes it goes back up again. A few times, it seems to loose connection completely, and needs to be turned off and on again. I've looked at the Apple support site, and have tried their recommendations (which are not really very relevant), but still nothing. I've tried setting the router to wpa2 only, and setting long-preamble. Right now, I guess I want to know if it's a hardware problem with my device and should be returned, or if it's a problem with all ipads which will be resolved. Guess I could take it back to the Mac genius bar, but I find those guys so incredibly pretentious and, frankly, rather useless, that i'd rather wait until I've exercised other options!

• scanf("%d", char*) - char-as-int format string?

  - by SF.

  What is the format string modifier for char-as-number? I want to read in a number never exceeding 255 (actually much less) into an unsigned char type variable using sscanf. Using the typical char source[] = "x32"; char separator; unsigned char dest; int len; len = sscanf(source,"%c%d",&separator,&dest); // validate and proceed... I'm getting the expected warning: argument 4 of sscanf is type char*, int* expected. As I understand the specs, there is no modifier for char (like %sd for short, or %lld for 64-bit long) is it dangerous? (will overflow just overflow (roll-over) the variable or will it write outside the allocated space?) is there a prettier way to achieve that than allocating a temporary int variable? ...or would you suggest an entirely different approach altogether?

• git: How to diff changed files versus previous versions after a pull?

  - by doug

  I'm new to git, using it via Terminal on Snow Leopard. When I run "git pull" I often want to know what changed between the last version of a file and the new one. Say I want to know what someone else committed to a particular file. How is that done? I'm assuming it's "git diff" with some parameters for commit x versus commit y but I can't seem to get the syntax. I also find "git log" confusing a bit and am not sure where to get the commit ID of my latest version of the file versus the new one.

• Imagemagick command line in PHP

  Hello everyone, I've got the following two commands for imagemagick in the command line: convert in.png container-mask.png +matte -compose CopyOpacity -composite out.png composite container.png out.png -compose multiply final.png Those two commands include 3 files: in.png: the file that should be masked container-mask.png: the back/white mask of the areas of container.png where in.png should be visible container.png image that includes the container for in.png, the one that has been masked in black/white with container-mask.png Now the question is how to transpose this commands into PHP calls. I've played around quite a bit, but I can't make sense of the API at http://php.net/manual/en/book.imagick.php Thanks and Bests, Charly

• What to name an array of flags?

  - by Chris

  I have a project where lots of the objects hold state by maintaining simple boolean flags. There are lots of these, so I maintain them within a uint32_t and use bit masking. There are now so many flags to keep track of, I've created an abstraction for them (just a class wrapping the uint32_t) with set(), clear(), etc. My question: What's a nice accurate, concise name for this class? What name could I give this class so that you'd have a reasonable idea what it was [for] knowing the name only? Some ideas I had: FlagBank FlagArray etc Any ideas? Thanks in advance! Cheers, -Chris

• Populate DataTable with LINQ in C#

• switch to mysqli a good idea?

  - by Rob

  I'm considering switching to mysqli for all my php projects. The way my code is written (I run very simple websites and built my own basic framework which I use across all of them) I shouldn't have too many problems modifying the functions and classes. However, i've only heard positive things about prepared statements, bar a few grumblings about the php functions available, most notably the lack of a simple replacement for using mysql_fetch_array in a while. This sounds a bit too good to be true, so I wondered if anyone could highlight some of the issues with using prepared statements, such as speed and resource usage.

• GPU YUV to RGB. Worth the effort?

  - by Jaime Pardos

  Hello, I have to convert several full PAL videos (720x576@25) from YUV 4:2:2 to RGB, in real time, and probably a custom resize for each. I have thought of using the GPU, as I have seen some example that does just this (except that it's 4:4:4 so the bpp is the same in source and destiny)-- http://www.fourcc.org/source/YUV420P-OpenGL-GLSLang.c However, I don't have any experience with using GPU's and I'm not sure of what can be done. The example, as I understand it, just converts the video frame to YUV and displays it in the screen. Is it possible to get the processed frame instead? Would it be worth the effort to send it to the GPU, get it transformed, and sending it again to main memory, or would it kill performance? Being a bit platform-specific, assuming I work on windows, is it possible to get an OpenGL or DirectDraw surface from a window so the GPU can draw directly to it?
