  • New harddrives failing within weeks.

    - by Jason Kealey
    I've experienced 8 hard disk failures in 3 months and have tried many things to solve the issue permanently but I have failed. I would like to know if you have any advice for me. System was running Win XP on an Asus P5W-DH Deluxe. I have setup a RAID-1 array. I started out with 2 x 500 GB 7200RPM Western Digital drives. One died. I took it out to RMA it. On the same day, the router was fried. Assumed a power surge occurred; connected an older UPS to protect the system. Once I got my hands on an identical disk, I installed it. The RAID array was rebuilt. A few days later, the other one died. Assumed the rebuild caused it to fail. Took it out for RMA. Before the other one arrived, the remaining one died. I then discovered I could re-enable them using the Intel Matrix Storage Manager. I re-enabled both and the system seemed fine for a week, until both died again. I got two new 1.5 TB 7200RPM Seagate drives and re-installed Windows 7. Also replaced the UPS and power supply. They both died again. The voltage on the plug is stable between 120 and 122V as per the UPS. None of the other devices have had any problems (monitors, etc.). At this point, I see two options: a) electrical issue in the house that was, for some reason, not blocked by the UPS. b) something else inside the system causing surges? motherboard? onboard raid controller? Failures happen fairly quickly, between 2 and 14 days after I fix the previous issue. I just gotten a new computer (Core i7) to replace it. If it is stable, I can determine that b) was the problem. If it fries its hard drive again, I can determine that it is an electrical issue in the house. Do you have any other thoughts? Any tools I can run on the drives that failed to get more information about the original SMART event history?

  • How to use Scanner to accept only valid int as input

    - by John
    I'm trying to make a small program more robust and I need some help with that. Scanner kb = new Scanner(System.in); int num1; int num2 = 0; System.out.print("Enter number 1: "); num1 = kb.nextInt(); while(num2<num1) { System.out.print("Enter number 2: "); num2 = kb.nextInt(); } Number 2 has to be greater than number 1 Also I want the program to automatically check and ignore if the user enters a character instead of a number. Because right now when a user enters for example r instead of a number the program just exits.

  • Why doesn't JFreeCharts correctly connect the points in my xy-line graph?

    - by Javajava
    /Each letter A,T,G,C represents a direction for the plot to graph. Specifically, “A” means move right, “T” is move down, “C” is move up, and “G” is move left. When the applet reads A,T,C, it plots the graph correctly. However, when I plot G, the graph is messed up. When I input "ACACACA," the graph is like a rising staircase. When I input "gtgtgt," the graph should look like a staircase, but it looks like a lightning bolt instead/ /This is all one code... i don't know why it's all split up like this:/ import java.applet.Applet; import java.awt.*; import java.awt.event.*; import java.util.Scanner.*; import java.jfree.chart.*; import java.jfree.data.xy.*; import java.jfree.chart.plot.PlotOrientation; public class If_Graph extends Applet implements ActionListener{ Panel panel; TextArea textarea, outputArea; Button move; String thetext; Scanner reader = new Scanner(System.in); String thetext2; int size,p,q; int x,y; public void init(){ setSize(500,500); //set size of applet panel = new Panel(); add(panel); setVisible(true); textarea= new TextArea(10,20); add(textarea); move=new Button("Graph"); move.addActionListener(this); add(move); } public void actionPerformed(ActionEvent e) { XYSeries series = new XYSeries("DNA Walk"); x= 0; y = 0; series.add(x,y); if(e.getSource() == move) { thetext=textarea.getText(); //the text is the DNA bases pasted thetext=thetext.replaceAll(" ",""); //removes spaces thetext2 = ""; for(int i=0; i<thetext.length(); i++) { char a = thetext.charAt(i); switch (a) { case 'A': //moves right x+=1; y+=0; series.add(x,y); break; case 'a': x+=1;y+=0; series.add(x,y); break; case 'C': //moves up x+=0; y+=1; series.add(x,y); break; case 'c': x+=0; y+=1; System.out.println(x + "," + y); series.add(x,y); break; case 'G': //move left x-=1; y+=0; series.add(x,y); System.out.println("G is: "+ x +"," +y); break; case 'g': x-=1; y+=0; System.out.println("g is: " +x + "," + y); series.add(x,y); break; case 'T': //move down x+=0; y-=1; series.add(x,y); System.out.println("T is: "+ x +"," +y); break; case 't': x+=0; y-=1; series.add(x,y); System.out.println("t is: "+ x +"," +y); break; default: // series.add(0,0); break; } } XYDataset xyDataset = new XYSeriesCollection(series); JFreeChart chart = ChartFactory.createXYLineChart ("DNA Random Walk", "", "", xyDataset, PlotOrientation.VERTICAL, true, true, false); ChartFrame frame1=new ChartFrame("DNA Random Walk",chart); frame1.setVisible(true); frame1.setSize(300,300); outputArea.setText(thetext2); } } }

  • How to change the default Help browser for VS2010?

    - by Scott Bilas
    Visual Studio 2010 changed the help system to run a little daemon and launch the system default web browser to view it. I'm using Firefox for my system browser but would like to use Chrome for VS help. Is there an option to change the Help browser that I'm not seeing in Tools|Options? If not, is there a workaround or registry setting to do this? As a backup I've been using H3Viewer but I'd like to be able to get context-sensitive F1 help from within the VS IDE.

  • BigInteger.Parse() on hexadecimal number gives negative numbers.

    - by brickner
    I've started using .NET 4 System.Numerics.BigInteger Structure and I've encountered a problem. I'm trying to parse a string that contains a hexadecimal number with no sign (positive). I'm getting a negative number. For example, I do the following two asserts: Assert.IsTrue(System.Int64.Parse("8", NumberStyles.HexNumber, CultureInfo.InvariantCulture) > 0, "Int64"); Assert.IsTrue(System.Numerics.BigInteger.Parse("8", NumberStyles.HexNumber, CultureInfo.InvariantCulture) > 0, "BigInteger"); The first assert succeeds, the second assert fails. I actually get -8 instead of 8 in the BigInteger. The problem seems to be when I'm the hexadecimal starts with 1 bit and not 0 bit (a digit between 8 and F inclusive). If I add a leading 0, everything works perfectly. Is that a bad usage on my part? Is it a bug in BigInteger?

  • Can I serialize a BitArray to XML?

    - by SimonNet
    Hello I have a business class which I need to serialize to xml. It has a BitArray property. I have decorated it with [XmlAttribute] but the serialization is failing with To be XML serializable, types which inherit from ICollection must have an implementation of Add(System.Boolean) at all levels of their inheritance hierarchy. System.Collections.BitArray does not implement Add(System.Boolean). I am not sure whether its possible to serialize to xml? If not what would be an efficient means of serializing the BitArray Thanks for looking

  • Choosing between assembler and COBOL

    - by Azares Cob
    I have to rewrite and greatly modify parts of a legacy COBOL application. The COBOL source-code is available (around 100.000 lines of copy & pasted code mixed with GOTOs). Some more details on the system: It is a general management system controlling transactions, bank management, customer data and employees of the company I work for. The COBOL-powered database is about 4 Terabytes distributed over 50 old HDDs. (But messing around with them is the sysadmins job) They are using COBOL85 only. Now I have two options: Rewrite and refactor 50% of the old COBOL system, or use X86 assembly. Should I use X86 assembler or COBOL?

  • ASP.Net MVC Web App not running

    - by Aidan Host
    Hi, I developed an ASP.Net MVC v1 web application and it ran fine on our server. The client wanted to move to another server, and the site does not run on the new host's server. The new server specs: Windows 2008 ASP.Net Framework v4 ASP.Net MVC 2 (afaik its included with .Net v4) IIS 7.5 (afaik) Error Message: Could not load file or assembly 'System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. My understanding is that it should be backwards compatible. Is the app really trying to run in ASP.Net MVC v1 when v2 is available? I have already tried deploying the MVC .dlls to the Bin folder, but it did not work. I also tried changing all the system.Web.Mvc Version values (in the web.config for the web app) from 1.0.0.0 to 2.0.0.0, which also did not work. Any assistance will be greatly appreciated.

  • How to validate Windows VC++ DLL on Unix systems

    - by Guildencrantz
    I have a solution, mostly C#, but with a few VC++ projects, that is pushed through our standard release process (perl and bash scripts on Unix boxes). Currently the initiative is to validate DLL and EXE versions as they pass through the process. All the versioning is set so that File Version is of the format $Id: $ (between the colon and the second dollar should be a git commit hash), and the Product Version is of the format $Hudson Build: $ (between the colon and the second dollar should be a string representing the hudson build details). Currently this system works extremely well for the C# projects because this version information is stored as plain strings within the compiled code (you can literally use the unix strings command and see the version information); the problem is that the VC++ projects do not expose this information as strings (I have used a windows system to verify that the version information is correctly being set), so I'm not sure how to extract the version on a unix system. Any suggestions for either A) Getting a string representation of the version embedded in the compiled code, or B) A utility/script which can extract this information?

  • How to run a restricted set of programs with Administrator privileges without giving up Admin acces (Win7 Pro)

    - by frLich
    I have a shared system, running Windows7 X64, restricted to a 'standard user' with no password. Not everyone who has access to the system has the administrator password. This works rather well, except for some applications - specially the unlock-applications for encrypted hard drives/USB flash drives. The specific ones either require Administrator access (eg. Seagate Blackarmor) or simply fail without it -- since these programs are sending raw commands to a device, this is to be expected. I would like to be able to add the hashes of these particular programs to a whitelist, and have them run as administrator without needing any prompts. Since these are by definition on removable media, I can't simply use a filename or even a path. One of the users who shares the system can be considered 'crafty', so anything which temporarily grants administrator rights to an user account is certain to cause problems. What i'd like to be able to do: 1) Create an admin account that can only run programs from a whitelist (or, failing that, from a directory) I can't find a good way to do this: As far as I can tell, SRP applies equally to ALL users? Even if I put a "Deny" token on all directories on the system, such that new directories would inherit it, it could still potentially run things from the mounted USB devices. I also don't know whether it's possible to create a new directory that DOESN'T inherit from the parent, that would lake the deny token, and provide admin access. 2) Find a lightweight service that will run these programs in its local context Windows7 seems to block cross-privilege level communication by default, and I haven't found such for windows 7. One example seems to be "sudo" (http://pages.cpsc.ucalgary.ca/~nfriess/sudo/) but because it uses a WLNOTIFY hook, it won't work under Vista nor Windows7 Non-Solutions: - RunAs: Requires administrator password! (but everyone calls it "sudo" anyway) - RunAs /savecred: Nice idea, but appears to be completely insecure. - RUNASSPC - Same concept as RunAs, uses "encrypted" files with credentials, but checks in user-space. - Scheduled Tasks - "Fixed" permissions make this difficult, and doesn't support interactive processes even if it did. - SuRun: From Google: "Surun uses its own Windows service that adds the user to the group of administrators during program start and removes him automatically from that group again"

  • .NET - Retrieve attribute from controller context?

    I have a controller insert action: <AcceptVerbs(HttpVerbs.Post)> _ Function InsertObject(<Bind(Exclude:="Id")> <ModelBinder(GetType(CustomModelBinder))> ByVal object As SomeObject) As ActionResult End Function And i have a CustomModelBinder class with a BindModel implementation: Public Function BindModel( _ ByVal controllerContext As System.Web.Mvc.ControllerContext, _ ByVal bindingContext As System.Web.Mvc.ModelBindingContext) As Object Implements System.Web.Mvc.IModelBinder.BindModel For Each s In HttpContext.Current.Request.Form.Keys HttpContext.Current.Response.Write(s & ": " & HttpContext.Current.Request.Form(s) & "<br />") Next HttpContext.Current.Response.End() End Function As you can see I have a controllerContext and a ModelBindingContext available. How do I get the: <Bind(Exclude:="Id")> part inside the BindModel implementation?

  • Is there anything like memcached, but for sorted lists?

    - by depesz
    I have a situation where I could really benefit from having system like memcached, but with the ability to store (per each key) sorted list of elements, and modifying the list by addition of values. For example: something.add_to_sorted_list( 'topics_list_sorted_by_title', 1234, 'some_title') something.add_to_sorted_list( 'topics_list_sorted_by_title', 5436, 'zzz') something.add_to_sorted_list( 'topics_list_sorted_by_title', 5623, 'aaa') Which I then could use like this: something.get_list_size( 'topics_list_sorted_by_title' ) // returns 3 something.get_list_elements( 'topics_list_sorted_by_title', 1, 10 ) // returns: 5623, 1234, 5436 Required system would allow me to easily get items count in every array, and fetch any number of values from the array, with the assumption that the values are sorted using attached value. I hope that the description is clear. And the question is relatively simple: is there any such system?

  • Calling C# from ColdFusion

    - by stomcavage
    I've written a .dll in C# to change the permissions on a folder. I also wrote an .exe to test the .dll and it successfully changes the permissions. Now I'm trying to call the .dll from ColdFusion, but I'm getting an error about System/Security/IPermission not being found. I'm assuming this is an interface in C# that ColdFusion can't find in any of the available assemblies on my system. I've added the System.Security assembly to my References in the C# project. Is there something else I need to do to make sure ColdFusion can find the interface? Here's how I'm using the .dll: <cfobject type="dotnet" name="permObj" assembly="#pathToDLLs#CoursePortal.dll" class="CoursePortal.Permissions"> <cfset permObj.revokePermissions(dir, username)>

The following are my current tricks for a Linux system serving over Apache with HTTPS and backed by Active Directory using LDAP authentication. Enabling KeepAlive on Apache Disable SVNPathAuthz Increase LDAP Cache Using the FSFS storage method instead of BDB Feel free to call this into question. I don't have hard proof that FSFS out performs BDB, only lots of tribal knowledge and hearsay.

  • Sequence diagram example

    - by Pamela
    The use case to model is the register of a new appointment. The user logins in the system as a patient (role). To make an appointment shoudl enter medical specialty and date. System shoudl look for the doctors availables for that specialty on that date. From the results patient should choose one and then system save the appointment. At the end user shoudl receive an email with the information of the appointment. The classes that I have in my model are: User PAtient Doctor Appointment DoctorShcedule and some more but I think these ones will be involve. I have this initial sequnce diagram: I have problem to set the return messages and also with the email step. Thanks

  • Verify p2p node

    - by mazzzzz
    Hey guys, I have been working on a p2p namespace for some of my programs. I created a system to encrypt/decrypt the packets send/received with the class. I was using the basic public private key system: 1) encrypt the data with Symmetric encryption 2) encrypt the symmetric key with RSA. Then do the opposite when you decrypted.. I was wondering though, how would you verify if the packet was coming from where it said it was. I was going to use a basic certificate system (where you encrypt with your private RSA key, then they decrypt it with your public key), but I don't know how to do this with C#. I am using the RSACryptoServiceProvider class. Does anyone know how do this? Thanks, Max

  • How to run shell script with live feedback from PHP?

    - by Highway of Life
    How would I execute a shell script from PHP while giving constant/live feedback to the browser? I understand from the system function documentation: The system() call also tries to automatically flush the web server's output buffer after each line of output if PHP is running as a server module. I'm not clear on what they mean by running it as a 'server module'. I attempted to run the script in the cgi-bin, but either I'm doing it wrong, or that's not what they mean. Example PHP code: <?php system('/var/lib/script_test.sh'); Example shell code: #!/bin/bash echo "Start..." for i in {1..10} do echo "$i..." sleep 1 done echo "Done."
