  • RAID and Partitions, guidance Needed

    - by beauregarde
    Alright I have a Biostar TA790GX3A2+ Mobo 2x Seagate 750Gb Hard drive (with 2 different speeds) an X4 9750 A GeForce 9800GT and 2GB RAM Hardware Specs link text I want to configure my computer with partitions in various RAID arrays. The Partitions I know i want (disk letters are mostly for reference here) C: XP Boot D: XP Swap E: XP Run F: Games G: Data The Partitions I think I want (repeat caveat) H: small FAT for Win Legacy and DOS I: Linux J: Linux Swap K-?M?: Other Linux /whatever partitions N & O: Attic for D1 and D2 What I'd like to do, is have C: written on Disk 1 (D1),.. D: on D2,.. E: and F: striped on D1 & D2,.. G: mirrored or D1 & D2,.. I: on D2 (so i can just switch disc boot priority to open in Ubuntu),.. J: on D1,.. and H: somewhere low on D1 I am inexperienced with VMs, so i am unsure as to whether those run out of XP, or whether i need to reserve a primary partition for them. However, I think they would be preferable for testing new OS's to scheduling a partition for the same purpose. I'm also not married to XP, but -64 IS pretty important to me. QUestion Time 1) Ignoring the irrationality of it all, is such a configuration possible? If not, can some pseudo-approximation be achieved? 2) My RAID is software, isnt it? 3) How much should I short a 750GB HD? And should i use that space for my attics, or for my attics and something else, or for something else (.iso's perhaps?)? 4) if XP is striped on D1 & D2, will that interfere egregiously with my Swap writes on D2? If so, would striping both XP and Swap relieve (or at least mitigate) that issue? Should XP and Swap just be written normally on 2 different HDs? 5) Should I keep DL's and Drivers on E: (XP Run), F: (Games), or elsewhere? 6) Is 4GB enough for C:? 7) Is 30GB enough (or too much) for E:? 8) How much to reserve for the Linux and sub-Linux partitions? Also, where on the platter do you think i should put them? 9) Am I a fool to use FAT16 instead of FAT32 for H: because I'd rather run 95 than 98SE? If not, do you think 2GB or 4GB? 10) I cant predict what my Max Commit Charge will be, so recommendations for Pagefile size? 5GB? 12GB? 11) VMs, where do I run them? do they exacerbate anything? Would it be better to just emulate Linux, 95, and DOS? EC) What havent I considered that I really should? Notes: computer is mostly for playing games and watching media, though I wouldnt rule out the use of particularly blah-intensive anything.

  • Ubuntu purple splash screen with blinking pixels?

    - by joxnas
    I had ubuntu 9.10 I upgraded to 10.04 after solving some problems (freeze at boot). Since then, I don't have the ubuntu's logo showing up when I boot, but a purple screen with some blinking pixels. I didn't care much about it... but today my computer took too long at that screen (normally it was just 1/4 second, but today it was like a minute..). And it happened like 4 or 5 times in a row (Only at the 5th time I realised that it was not freezing up, but it simply would took more time) After a reboot, it is again 1/4 second of purple screen but I don't want this problem to return.. so I want to get rid of the purple screen (I think it is an indicator of the problem) Well, I already installed the graphic drivers (going to system admnistration hardware drivers). But it didn't solve anything. (I don't know if it is even related) I searched in google, found something old (2006) and I think it maybe has some relation with my problems .. http://ubuntuforums.org/archive/index.php/t-294692.html But couldn't understand the conversation (i'm a linux novice) Sorry for my horrible english.. I would appreciate any help! My hardware: ATI Mobility Radeon 4650 HD P7450 2.13Ghz Core 2 Duo

  • Automatically determining the size of a UITableViewCell

    - by hanno
    I am trying to determine the size of a UITableCellView. The reason being that I am using one class for different orientations and devices. The cell contains one subview that is supposed to fill the entire cell. Right know I'm doing this in the UITableViewCell's init method: if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad){ //iPad subv = [[OrbitView alloc] initWithFrame:CGRectMake(52, 5, 660, 420) ]; }else{ //iPhone subv = [[OrbitView alloc] initWithFrame:CGRectMake(15, 5, 290, 200) ]; } Clearly, there must be a better way of doing this, without the magic numbers. How/Where should I set the frame of the subview in the UITableViewCell so that it fills the entire UITableViewCell?

  • Java array assignment (multiple values)

    - by Danny King
    Hello, I have a Java array defined already e.g. float[] values = new float[3]; I would like to do something like this further on in the code: values = {0.1f, 0.2f, 0.3f}; But that gives me a compile error. Is there a nicer way to define multiple values at once, rather than doing this?: values[0] = 0.1f; values[1] = 0.2f; values[2] = 0.3f; Thanks!

  • Learning Recommendations? Classroom? Tutorials?

    - by cdg
    Hi there. Does anyone have any recommendations for a class (online) or tutorial that teaches android programing for dummies? It's frustrating knowing exactly what you want to do and no idea how to do it. Something that uses basic language and explains each line in detail to help a person remember how to do it later. Any suggestions would be great. Thanks.

  • How to make a structure map powered viewengine in asp.net mvc

    - by Andrew Bullock
    My views extend a base view class ive made: public class BaseView : ViewPage At the moment im calling ObjectFactory.GetInstance inside this class' constructor to get some interface implementations but id like to use structuremap to inject them as constructor arguments. Im using a structuremapcontrollerfactory to create my controllers, but how can i do the same for views? I know i can implement a custom ViewEngine, but using reflector to look at the mvc default viewengine and its dependencies, it seems to go on and on and i'd rather not have to re-implement stuff thats already there. Has anyone got a cunning idea how to solve this? I know i could make things easier with setter instead of constructor injection but id rather avoid that if possible.

  • Multiple Headers in asp.net

    - by digiguru
    I'm running code that seems to hit the "AppendHeader" twice in the code. Response.Filter = New DeflateStream(Response.Filter, CompressionMode.Compress, True) Response.AppendHeader("Content-encoding", "deflate") ... Response.AppendHeader("Content-encoding", "deflate") I have tried using the following.... Response.Headers("Content-encoding") = "deflate" But it says This operation requires IIS integrated pipeline mode. How do I check for a headers existence, and overwrite it rather than appending it.

  • Installing mysql on leopard: "Can't connect to local MySQL server through socket"

    - by Neil
    I migrated to a new machine and used migration assistant to copy across my files (which seemed to copy across the DBs) but I had to use macports to install Mysql (whereas last time I compiled from source via Dan Benjamin's guide). For some reason, mysql is intermittently throwing the following error; Can't connect to local MySQL server through socket '/opt/local/var/run/mysql5/mysqld.sock' (2) It does this no matter what I try, which has included setting the socket in /opt/local/etc/mysql5/my.cnf. Previously I've managed to temporarily fix this by restarting the machine, but right now it just doesn't want to know, despite grep mysql telling me I seem to have a pid; 0 46 1 0 0:00.01 ?? 0:00.01 /opt/local/bin/daemondo --label=mysql5 --start-cmd /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper start ; --stop-cmd /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper stop ; --restart-cmd /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper restart ; --pid=none 0 70 1 0 0:00.01 ?? 0:00.01 /bin/sh /opt/local/lib/mysql5/bin/mysqld_safe --datadir=/opt/local/var/db/mysql5 --pid-file=/opt/local/var/db/mysql5/localhost.pid 74 100 70 0 0:09.22 ?? 1:02.68 /opt/local/libexec/mysqld --basedir=/opt/local --datadir=/opt/local/var/db/mysql5 --user=mysql --pid-file=/opt/local/var/db/mysql5/localhost.pid --socket=/tmp/mysql.sock 501 66217 65266 0 0:00.00 ttys001 0:00.00 grep mysql How do I fix this? Are there any steps I can take next? I've been trying for a few weeks now and I've read round all relevant blog posts, so I'm completely out of ideas.

  • Using thrift with PHP and Java

    - by Christopher McCann
    I am getting myself a bit confused about how to go about this. My plan is to use PHP to perform the final page construction and this PHP web app will contact multiple services, which i will also to develop, for the data. Lets say one of those services was done in Java. I would define a Java interface which was implemented by a concrete class. This is where I get confused - how does Thrift link the PHP web app with the java service or am I getting totally mixed up?? Thanks

  • XPath doesn't work as desired in C#

    - by Nick Brooks
    My code doesn't return the node XmlDocument xml = new XmlDocument(); xml.InnerXml = text; XmlNode node_ = xml.SelectSingleNode(node); return node_.InnerText; // node_ = null !!!!!!!!!!!!!!!!!!! I'm pretty sure my XML and Xpath are correct My Xpath : /ItemLookupResponse/OperationRequest/RequestId' My XML : <?xml version="1.0"?> <ItemLookupResponse xmlns="http://webservices.amazon.com/AWSECommerceService/2005-10-05"> <OperationRequest> <RequestId>xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx</RequestId> .......(the rest of the xml is irrelevant).......... The node my XPath returns is always null for some reason. Can someone help?

  • How does one build Mono with only the ECMA covered parts?

    - by Zifre
    I'm trying to figure out how to build Mono without the patented, non ECMA components, such as Winforms. Miguel de Icaza said that Mono would be split in two, so that we could build only the parts under Microsoft's Community Promise. It doesn't seem like this has happened yet. Is there any way to do this yet?

  • efficient thread-safe singleton in C++

    - by user168715
    The usual pattern for a singleton class is something like static Foo &getInst() { static Foo *inst = NULL; if(inst == NULL) inst = new Foo(...); return *inst; } However, it's my understanding that this solution is not thread-safe, since 1) Foo's constructor might be called more than once (which may or may not matter) and 2) inst may not be fully constructed before it is returned to a different thread. One solution is to wrap a mutex around the whole method, but then I'm paying for synchronization overhead long after I actually need it. An alternative is something like static Foo &getInst() { static Foo *inst = NULL; if(inst == NULL) { pthread_mutex_lock(&mutex); if(inst == NULL) inst = new Foo(...); pthread_mutex_unlock(&mutex); } return *inst; } Is this the right way to do it, or are there any pitfalls I should be aware of? For instance, are there any static initialization order problems that might occur, i.e. is inst always guaranteed to be NULL the first time getInst is called?

  • jQuery, html5, append()/appendTo() and IE

    - by karbassi
    How to replicate: Create an html5 page. Make sure you have the script from remysharp.com/2009/01/07/html5-enabling-script/ added so that IE will notice the tags. Create an hardcoded <section id='anything'></section> tag. Using jQuery 1.3.2, append another section tag: $('#anything').append('<section id="whatever"></section>'); So far, everything works in all the browsers. Repeat the previous step. $('#whatever').append('<section id="fail"></section>'); This is where IE6/7 fails. Firefox/Safari will continue working. Error This is the error displayed. Thoughts It could be that IE6/7 can't handle the HTML5 section tag. I say this because when I change step 4 from <section> to <div>, IE6/7 will start working. If I use document.createElement() and create my new element, it works, but it seems like jQuery's append() has a problem with html5 elements.

  • PHP/Oracle Connectivity randomly "drops out"

    - by user20555
    Hi! Here's the current situation - I have two web servers (for now named A and B) and two database servers (named C and D). The web servers are quite old, and are running an early version of Apache 2 + PHP4, while the DB servers are running Oracle 9i and 10g respectively. We're experiencing a strange problem connecting (via PHP code) to database A while on web server B only. Web server A has no issues at all... Randomly, web server B will report a "Not connected to Oracle" error (3114). I can't see a real pattern with this, but refreshing a few times seems to fix the issue. Apparently there are no drop-outs on the network interface, which leads me to believe that there's some misconfiguration between PHP/Apache and Oracle (which uses connection pooling). We're running SunOS 5.8... Any ideas?

  • More than one XP Mode virtual machines okay under Win 7?

    - by kousen
    I really like the Windows XP Mode virtual machine that comes with Windows 7 (once you download the integration components). I teach technical training classes, and having a machine configured for the classroom is very helpful. My question is, can I configure more than one? The documentation suggests you can make multiple virtual machines, but I can't tell if I can have multiple "Windows XP Mode" VMs. It can't be as simple as configuring one, then just making a copy of the primary disk file, could it? I only plan to run one at a time, but I'd like to configure multiple different VMs for different classes, all running XP if possible. Thanks for any help!

  • Unexpected "Connection timed out: proxy connect" lines in Apache error.log

    - by Gregg Lind
    I see some unexpected lines in my Apache (1.3!) error.log. What is happening here? My isp has complained in the past about proxying attempts... how do I check for them?

  • How to dictate a Non-English text on an English Windows 7?

    - by hellelampe
    I'm using an English Windows 7 with speech recognition working fine if I'm dictating in English. I would like to dictate a letter in German. I don't need further features that let you use your computer without a mouse, I want to dictate my letter. If I just start speaking German the Windows speech recognition software just gives me English gibberish. When I set the Speech Recognition to "German" in the Speech Properties dialog, I get the error message: Speech Recognition could not start because the language configuration is not supported. The recognizer language must match the language of the user interface. Please change the recognizer language in the Speech Recognition control panel under Advanced Options. This error message doesn't help me, because it tells me that I either need to change my system language or the language I want to dictate. But that's not what I want. How can I dictate in German on my PC with the English version of Windows 7?

  • FileNotFoundException when reading .xml file to parse

    I'm writing a program in Java where I read in data from an XML file and parse it. The file is imported into a folder named "Resources" in the src directory of my project. I'm using Eclipse. When I run the program, I get the following error: java.io.FileNotFoundException: /Users/thechiman/Dropbox/introcs/PSU SOC Crawler/resources/majors_xml_db.xml (No such file or directory) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(FileInputStream.java:106) at java.io.FileInputStream.<init>(FileInputStream.java:66) ...

  • RTF formatting in jasper reports

    I have a report which I generate RTF format off that. It displays fine on the jsp page or in the ireports preview but when it generates the RFT format, it gives me the "Invalid text height" error. I have no idea which field is causing this error, is there a way in ireports to drill down exactly which field is causing it?
