  • Diagnosing PC crashes (most often while using shared folders or torrents)

    - by Dyppl
    For the last few weeks my PC (pretty old P4 with WinXP SP3) has been crashing randomly. It just suddenly reboots instanteneously. It feels hardware-related but I wasn't able to determine wether it's software or hardware that causes it. I did notice a pattern though: it's more likely to crash when I copy a lot of files over network or have uTorrent running, but sometimes it crashes when I am not doing anything with it. Copying files from it over network causes it to crash in 1 to 10 minutes almost every time. Using torrents causes it to crash every 1-3 hours. With neither or that on it crashes every 24 hours or so. I ruled out the following probable causes: PSU (I bought a new one and turned off most of the drives so the power is sufficient 100%) Bad HDD or interface cable on my SATA disk from which I was originally copying the data over network (bought new SATA cable and later yanked out the HDD completely, PC still crashes without it) Video adapter (AGP slot is now empty, using the onboard VGA at the moment) Network adapter (removed it from PCI, using onboard LAN) CPU (I think: I changed the termopaste and it's temperature is below 50C) RAM (I think: I ran Memtest86 and it didn't show any errors) At the moment I only have only one system HDD and DVD drives, a mouse and a keyboard plugged in. The fact that it crashes most often when I use network extensively makes me think that maybe it's software related (I removed the network adapter from PCI and now am using an onboard one, so network hardware is unlikely to cause problems). I am now pondering system reinstall but it's not a pleasant solution so I decided to ask wether there are better ideas first. If someone can share a good diagnostic tool it would be great because I didn't find anything good. Thanks in advance, I hope that "help to diagnose" questions aren't entirely banned here. EDIT: Motherboard is actually ~4 years old as I replaced it back in 2007

  • Ajaxtoolkit TextboxWatermarkExtender: How to change the text from Javascript

    - by George
    I think thaAjaxControlToolkitTextBoxWrapperThis use to work, but I think that upgrading to te latest version of teh Toolkit (4 something) broke it: var txtExpireYear = document.getElementById("ctl00_phPageContent_dtmPassportExpirationDate_txtYear"); txtExpireYear.AjaxControlToolkitTextBoxWrapper.set_Value(dtmDateOfExpire.getFullYear()); I now get the error: Microsoft JScript runtime error: 'AjaxControlToolkitTextBoxWrapper' is null or not an object Executing this: txtExpireYear.innerText="value1" txtExpireYear.value="value2" results in the watermark text being changed, not the textbox's text.

  • Given year, month and day, all in int, how would I generate an NSDate

    - by BU
    I think the solution is really simple, I just haven't come across it online. Suppose I am given int year, int month, int day, int hour, int min, int sec.. how do I generate NSDate out of it? I know we can use [NSDate initWithString:] but I think it gets complicated if month/day/hour/min/sec are one digit numbers. Thanks in advance for your help.

  • Django: How to get current user in admin forms

    - by lazerscience
    In Django's ModelAdmin I need to display forms customized according to the permissions an user has. Is there a way of getting the current user object into the form class, so that i can customize the form in its __init__ method? I think saving the current request in a thread local would be a possibility but this would be my last resort think I'm thinking it is a bad design approach....

  • What are all the differences between pipes and message queues?

    - by aks
    What are all the differences between pipes and message queues? Please explain both from vxworks & unix perspectives. I think pipes are unidirectional but message queues aren't. But don't pipes internally use message queues, then how come pipes are unidirectional but message queues are not? What are the other differences you can think of (from design or usage or other perspectives)?

  • How to parse bbcodes safely?

    - by Emily
    I'm trying to parse BBcodes in php but i don't think my code is safe at all. $Text = preg_replace("(\[color=(.+?)\](.+?)\[\/color\])is","<span style=\"color: $1\">$2</span>",$Text); I think you can pass an injection like this and it will work: [color=<script>alert('gotcha');</script>] How to improve my regex to only capture the two standar color formats: [color=red] OR [color=#FF0000] Thanks

  • Where specifically do UIImageWriteToSavePhotosAlbum or UISaveVideoAtPathToSavedPhotosAlbum save thei

    - by Chris Markle
    Simple question I think and I'll be trying ot myself to see... When people talk about using UIImageWriteToSavePhotosAlbum or UISaveVideoAtPathToSavedPhotosAlbum is the "saved photos album" the "Camera Roll" or the "Photo Library" (or something else either than these two) that I see in the Photo Albums application? I don't think the doc makes it super-explicit as to which it is...

  • Is there a compiled* programming language with dynamic, maybe even weak typing?

    - by sub
    I wondered if there is a programming language which compiles to machine code/binary (not bytecode then executed by a VM, that's something completely different when considering typing) that features dynamic and/or weak typing, e.g: Think of a compiled language where: Variables don't need to be declared Variables can be created doing runtime Functions can return values of different types Questions: Is there such a programming language? (Why) not? I think that a dynamically yet strong typed, compiled language would really sense, but is it possible?

  • How to remove lowercase sentence fragments from text?

    - by Aaron
    Hello: I'm tyring to remove lowercase sentence fragments from standard text files using regular expresions or a simple Perl oneliner. These are commonly referred to as speech or attribution tags, for example - he said, she said, etc. This example shows before and after using manual deletion: Original: "Ah, that's perfectly true!" exclaimed Alyosha. "Oh, do leave off playing the fool! Some idiot comes in, and you put us to shame!" cried the girl by the window, suddenly turning to her father with a disdainful and contemptuous air. "Wait a little, Varvara!" cried her father, speaking peremptorily but looking at them quite approvingly. "That's her character," he said, addressing Alyosha again. "Where have you been?" he asked him. "I think," he said, "I've forgotten something... my handkerchief, I think.... Well, even if I've not forgotten anything, let me stay a little." He sat down. Father stood over him. "You sit down, too," said he. All lower case sentence fragments manually removed: "Ah, that's perfectly true!" "Oh, do leave off playing the fool! Some idiot comes in, and you put us to shame!" "Wait a little, Varvara!" "That's her character," "Where have you been?" "I think," "I've forgotten something... my handkerchief, I think.... Well, even if I've not forgotten anything, let me stay a little." He sat down. Father stood over him. "You sit down, too," I've changed straight quotes " to balanced and tried: ” (...)+[.] Of course, this removes some fragments but deletes some text in balanced quotes and text starting with uppercase letters. [^A-Z] didn't work in the above expression. I realize that it may be impossible to achieve 100% accuracy but any useful expression, perl, or python script would be deeply appreciated. Cheers, Aaron

  • what does macosx-version-min imply?

    - by Quincy
    When I pass compiler flag "-mmacosx-version-min=10.5", what does it mean? I think it implies the result binary is x86, not ppc, but is it 32 bits or 64 bits? I'm compiling on snow leopard, so default output binary is 64 bits. I'm not passing -universal, it's not 32bit-64bit universal binary, I think.

  • Register all GUI components as Observers or pass current object to next object as a constructor argu

    - by Jack
    First, I'd like to say that I think this is a common issue and there may be a simple or common solution that I am unaware of. Many have probably encountered a similar problem. Thanks for reading. I am creating a GUI where each component needs to communicate (or at least be updated) by multiple other components. Currently, I'm using a Singleton class to accomplish this goal. Each GUI component gets the instance of the singleton and registers itself. When updates need to be made, the singleton can call public methods in the registered class. I think this is similar to an Observer pattern, but the singleton has more control. Currently, the program is set up something like this: class c1 { CommClass cc; c1() { cc = CommClass.getCommClass(); cc.registerC1( this ); C2 c2 = new c2(); } } class c2 { CommClass cc; c2() { cc = CommClass.getCommClass(); cc.registerC2( this ); C3 c3 = new c3(); } } class c3 { CommClass cc; c3() { cc = CommClass.getCommClass(); cc.registerC3( this ); C4 c4 = new c4(); } } etc. Unfortunately, the singleton class keeps growing larger as more communication is required between the components. I was wondering if it's a good idea to instead of using this singleton, pass the higher order GUI components as arguments in the constructors of each GUI component: class c1 { c1() { C2 c2 = new c2( this ); } } class c2 { C1 c1; c2( C1 c1 ) { this.c1 = c1 C3 c3 = new c3( c1, this ); } } class c3 { C1 c1; C2 c2; c3( C1 c1, C2 c2 ) { this.c1 = c1; this.c2 = c2; C4 c4 = new c4( c1, c2, this ); } } etc. The second version relies less on the CommClass, but it's still very messy as the private member variables increase in number and the constructors grow in length. Each class contains GUI components that need to communicate through CommClass, but I can't think of a good way to do it. If this seems strange or horribly inefficient, please describe some method of communication between classes that will continue to work as the project grows. Also, if this doesn't make any sense to anyone, I'll try to give actual code snippets in the future and think of a better way to ask the question. Thanks.

  • Web P2P video confrence solution

    - by dtroy
    I'm looking for the best possible solution which will allow me to incorporate live video/audio conference between 2 users(only 2 at this point) into a flash gaming platform. The video chat is not just an extra feature, it's the main one. I'm mainly looking at open source implementations or something I'll be able to implement myself, but will consider commercial products if they are exactly what I need. Here are a few things I've looked at, but so far, I didn't find any of them good enough: Flash player 10's P2P capabilities sound promising, but I am aware of the fact that Adobe has not release any information on the RTMFP protocol and that there is no commercial server which supports it at this point. Stream all the video/audio live through a flash server (not p2p), but from my personal experience you don't get a smooth conversation. I think TokBox uses this method Java applets are a possible solution too (to perform p2p), but I don't think it will be a nice and elegant solution to combine them in the game at this point (and requires the user to authorize them). BTW, I couldn't find any useful implementations. So, If you know of any, i'll look into them. Google Gmail Video Chat uses a custom (and proprietary) browser plug-in which does the p2p and streams the video/audio into the flash player. This is a possible solution, but I rather not implement the entire p2p protocol stack + browser plug-in at this stage and concentrate on other aspect of the game itself. I think they are using XMPP based protocol similar to Jingle and they've release a Jingle librarby but without the video confrencing implementation. EDIT: In response to Branden: I am aware of Adobe Stratus. Stratus is a beta, hosted rendezvous service that aids establishing communications between Flash Player endpoints (RTMFP server). This current release of the Stratus is prerelease and is designed for evaluation purposes only. The service is not final. There is no guarantee that the service will continue to exist in the future or any information about the future cost. That's why I don't think it can be used as a commercial solution. At least not yet. I'd appreciate your suggestions and advice. thanks!

  • Where to put a glossary of important terms and patterns in documentation?

    - by Tetha
    Greetings. I want to document certain patterns in the code in order to build up a consistent terminology (in order to easen communication about the software). I am, however, unsure, where to define the terms given. In order to get on the same level, an example: I have a code generator. This code generator receives a certain InputStructure from the Parser (yes, the name InputStructure might be less than ideal). This InputStructure is then transformed into various subsequent datastructures (like an abstract description of the validation process). Each of these datastructures can be either transformed into another value of the same datastructure or it can be transformed into the next datastructure. This should sound like Pipes and Filters to some degree. Given this, I call an operation which takes a datastructures and constructs a value of the same datastructure a transformation, while I call an operation which takes a datastructure and produces a different follow-up datastructure a derivation. The final step of deriving a string containing code is called emitting. (So, overall, the codegenerator takes the input-structure and transforms, transforms, derives, transforms, derives and finally emits). I think emphasizing these terms will be benefitial in communications, because then it is easy to talk about things. If you hear "transformation", you know "Ok, I only need to think about these two datastructures", if you hear "emitting", you know "Ok, I only need to know this datastructure and the target language.". However, where do I document these patterns? The current code base uses visitors and offers classes called like ValidatorTransformationBase<ResultType> (or InputStructureTransformationBase<ResultType>, and so one and so on). I do not really want to add the definition of such terms to the interfaces, because in that case, I'd have to repeat myself on each and every interface, which clearly violates DRY. I am considering to emphasize the distinction between Transformations and Derivations by adding further interfaces (I would have to think about a better name for the TransformationBase-classes, but then I could do thinks like ValidatorTransformation extends ValidatorTransformationBase<Validator>, or ValidatorDerivationFromInputStructure extends InputStructureTransformation<Validator>). I also think I should add a custom page to the doxygen documentation already existing, as in "Glossary" or "Architecture Principles", which contains such principles. The only disadvantage of this would be that a contributor will need to find this page in order to actually learn about this. Am I missing possibilities or am I judging something wrong here in your opinion? -- Regards, Tetha

  • Emulating hyperlink functionality in datawindow text fields

    - by mortalitysequence
    The idea is rather simple. Some datawindow (not web datawindow) varchar fields contain detailed descriptions. I was wondering if it is possible to provide the following (wikipedia-like) functionality to users: The ability to click (or dbl-click or whatever) on specific words of the text, while reading (which somehow should be indicated as clickable - it would be perfect if they could be colored blue but I don't think this is possible) and open a relevant window (or response). Do you think something like this could be implemented?

  • weird array syntax

    - by dnagirl
    I'm trying to figure how a function I've been given works -- or rather doesn't work. The problematic areas include array notation like this: $small[$end[$i]{0}] I think the idea is to append "0" to the value of $end[$i] and use that for the index of $small. But it doesn't work in PHP5.3. Is this a deprecated syntax and is it trying to do what I think it is?
