  • Monitor and Terminate Python script based on system resource use

    - by Vincent
    What is the "right" or "best" way to monitor the system resources a python script is using and terminate it if the resource use exceeds some predetermined values. In my case memory usage is of concern. I am not asking how to measure the system resource use although I am open to suggestions. As a simple example, let's assume I have a function that finds prime numbers less than some large number and adds them to a list based on some condition. I don't know ahead of time how many prime numbers will satisfy the condition so I what to be sure to terminate the function if I use up to much system memory (8gb lets say). I know that there are ways to monitor the size of python objects. What I don't know is the proper way to monitor the size of the list and exit is to just include a size test in the prime function loop and exit if it exceeds 8gb or if there is an "external" way to monitor and exit.

  • Handle leaks with .NET System.Threading.Thread class

    - by Mahno
    I've a problem that number of Handles in my app is continuously growing. I did the debugging and recognize that this is caused by System.Threading.Thread class which is used for some routine. To simplify the debugging I’ve created a sample .NET application: ... private void button1_Click(object sender, EventArgs e) { Thread t = new Thread(DoWork); t.Start(); } public void DoWork(object parameter) { // Do something... } ... Each time I’m clicking the button, a thread is created using System.Threading.Thread class. The problem is that looks like the thread do not frees Handles because each click cause number of Handles growing by ~5. The question is: how can I manually free all Handles created by System.Threading.Thread class? Thanks in advance.

  • design question for transportation agency/workflow system

    - by George2
    Hello everyone, I am designing a transportation agency/workflow system, and it including 3 types of people, customer who requests to transport some stuff, drivers who deliver the stuff, and truck manager who manages transport source/destination truck coordination and communicates/organizes drivers. The system is expected to be a web site, and 3 kinds of people could use the web site to submit request, accept request, monitor status of specific stuff transportation, etc. The web site is more like an open agency or a workflow system. I am wondering whether there are any existing technologies, tools or projects (better to be open source, but not a must) which I could build my application faster based on? I prefer to use .Net technologies, but not a must. thanks in advance, George

  • ASP.NET: Unable to validate data.

    - by SoloBold
    What is the cause of this exception in ASP.NET?

  • System.Threading.Timer example to run and display seconds until you click a button

    - by Roy
    Hi, I am having some issues creating an asp.net page using C# When you first click a button it starts the display of seconds via a label control. When you click the button again the seconds stop. Currently my code behind looks like this: System.Threading.Timer Timer; bool endProcess = false; int i = 0; protected void Page_Load(object sender, EventArgs e) { Timer = new System.Threading.Timer(TimerCallback, null, 10, 10); } private void TimerCallback(object state) { Label1.Text = i.ToString(); i++; if (endProcess == true) { Timer.Dispose(); return; } } public void Button1_Click(object sender, System.EventArgs e) { endProcess = true; }

  • a direct, simple api to run as system?

    - by fejesjoco
    Suppose a program is running with elevated privileges already, and it needs to see the contents of the System Volume Information folder, and by default, only NT Authority\System can do that. A workaround would be to change ACL's on the folder, but I don't want to mess with that. I already found two ways to do it: the task scheduler and psexec. They are too indirect, I don't even need to describe the first one, and the second one works by installing a windows service, running it, telling it to run whatever I wanted to run, then uninstalling the service. Now the question is: is there a direct, simple WinAPI function to run something as system? I don't think that such an API would circumvent the security restrictions, as an administrator I have the right to schedule a task or install a service, so there must be a shortcut.

  • Session is null when inherit from System.Web.UI.Page

    - by Andreas K.
    I want to extend the System.Web.UI.Page-class with some extra stuff. In the ctor I need the value of a session-variable. The problem is that the Session-object is null... public class ExtendedPage : System.Web.UI.Page { protected foo; public ExtendedPage() { this.foo = (int)HttpContext.Current.Session["foo"]; // NullReferenceException } } If I move the part with the session-object into the Load-Event everything works fine... public class ExtendedPage : System.Web.UI.Page { protected foo; public ExtendedPage() { this.Load += new EventHandler(ExtendedPage_Load); } void ExtendedPage_Load(object sender, EventArgs e) { this.foo = (int)HttpContext.Current.Session["foo"]; } } Why is the Session-object null in the first case??

  • Missing System.Core.dll and others on Visual Studio 2010 Project targeting 3.5 Framework

    - by Mark Struzinski
    I just got Visual Studio 2010 installed and running on my development machine (alongside VS 2008). The first thing I did was make a copy of an existing project and convert it up to the VS 2010 project. I told the conversion wizard to leave the project targeting the 3.5 framework. The project compiles and runs just fine in VS 2008. When I go to build it, several of my references are marked as missing (System.Core, System.Xml.Linq, System.Data.DataSetExtensions). When I go to the Add Reference dialog, they are not present. Yet if I view the GAC at C:\Windows\Assembly, I can see the entries there. I have tried converting the projects to 4.0, then back down to 3.5, and also unloading/reloading the projects. Nothing works. Has anyone else ran across this problem?

  • Using the system localizations on iPhone

    - by nevan
    I want to make a back button for a navigation controller with the title "Back" instead of the title of the previous controller. I'm using this code: UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Back", @"Back") style:UIBarButtonItemStyleBordered target:nil action:nil]; self.navigationItem.backBarButtonItem = backButton; I'd like to be able to skip localizing the "Back" string in my app (since I can only localize it in a limited number of languages). If I give my navigation controller no title, the back button will be automatically localized into whatever the language the user has chosen, so the system has translations of "Back" in many languages. Is there a way to access the localizations that are already present in the system and use them myself? These are things like "Back", "Cancel", "Done" and so on, which show up when creating one of the standard system buttons.

  • a completely decoupled OO system ?

    - by shrini1000
    To make an OO system as decoupled as possible, I'm thinking of the following approach: 1) we run an RMI/directory like service where objects can register and discover each other. They talk to this service through an interface 2) we run a messaging service to which objects can publish messages, and register subscription callbacks. Again, this happens through interfaces 3) when object A wants to invoke a method on object B, it discovers the target object's unique identity through #1 above, and publishes a message on the message service for object B 4) message services invokes B's callback to give it the message 5) B processes the request and sends the response for A on message service 6) A's callback is called and it gets the response. I feel this system is as decoupled as practically possible, but it has the following problems: 1) communication is typically asynchronous 2) hence it's non real time 3) the system as a whole is less efficient. Are there any other practical problems where this design obviously won't be applicable ? What are your thoughts on this design in general ?

  • How to use email adresses with special chars such as Ø

    - by Sir Code-A-Lot
    By writing this: var recipient = new MailAddress("name@abcø.dk"); Notice the "ø" in the domain part. I get an exception stating: System.FormatException: The specified string is not in the form required for an e-mail address. at System.Net.Mime.MailBnfHelper.ReadMailAddress(String data, Int32& offset, String& displayName) at System.Net.Mail.MailAddress.ParseValue(String address) at System.Net.Mail.MailAddress..ctor(String address, String displayName, Encoding displayNameEncoding) at System.Net.Mail.MailAddress..ctor(String address) The address used should be perfectly valid. So I'm guessing I have to encode the address somehow?

  • change an absolutely positioned webpage into a centered one

    - by Jonathan
    So I have this template design that is currently absolutely positioned, but I'm trying to make it centered in any widescreen browser.

  • Why so many individual System.Web.* DLLs?

    - by toasteroven
    I've been thinking about ways to refactor a fairly expansive class/utility library I have, and one thing I think I want to do is split off any higher-level helper utilities that introduce new dependencies. I read some previous questions here, and one that I particularly noticed was a comment about how Microsoft freely uses namespaces across DLLs. The example given was System.Web - it's in the base framework, but there's also a System.Web.dll that adds more functionality to the namespace if you want it. I also noticed several other System.Web.* DLLs available, and I was wondering if there's a reason why they wouldn't be combined into a single DLL. Could it be that they have their own individual dependencies and Microsoft (like me) wanted to separate assemblies along those lines? Or is it for easier maintenance? Something else entirely?

  • Best use of System.Windows.Forms.Application.Run()

So far I used the first approach without any problem. Thanks for your comments !

  • system() call returns "Permission Denied" on Windows XP

    - by bde
    I am experiencing a problem with a C program running on Windows XP that is getting Permission Denied (EACCES) errors when it tries to call system(). It doesn't seem to matter what I put in the command string, the commands all work manually but get Permission Denied errors when executed via system() The other interesting thing is that the program works correctly on other XP machines, just not this one. That makes it feel like some kind of OS setting, but I am not totally sure what system() does under the hood and would like to understand what is happening here. Thanks.

  • Why do we need different CPU architecture for server & mini/mainframe & mixed-core?

    - by claws
    Hello, I was just wondering what other CPU architectures are available other than INTEL & AMD. So, found List of CPU architectures on Wikipedia. It categorizes notable CPU architectures into following categories. Embedded CPU architectures Microcomputer CPU architectures Workstation/Server CPU architectures Mini/Mainframe CPU architectures Mixed core CPU architectures I was analyzing the purposes and have few doubts. I taking Microcomputer CPU (PC) architecture as reference and comparing others. Embedded CPU architecture: They are a completely new world. Embedded systems are small & do very specific task mostly real time & low power consuming so we do not need so many & such wide registers available in a microcomputer CPU (typical PC). In other words we do need a new small & tiny architecture. Hence new architecture & new instruction RISC. The above point also clarifies why do we need a separate operating system (RTOS). Workstation/Server CPU architectures I don't know what is a workstation. Someone clarify regarding the workstation. As of the server. It is dedicated to run a specific software (server software like httpd, mysql etc.). Even if other processes run we need to give server process priority therefore there is a need for new scheduling scheme and thus we need operating system different than general purpose one. If you have any more points for the need of server OS please mention. But I don't get why do we need a new CPU Architecture. Why cant Microcomputer CPU architecture do the job. Can someone please clarify? Mini/Mainframe CPU architectures Again I don't know what are these & what miniframes or mainframes used for? I just know they are very big and occupy complete floor. But I never read about some real world problems they are trying to solve. If any one working on one of these. Share your knowledge. Can some one clarify its purpose & why is it that microcomputer CPU archicture not suitable for it? Is there a new kind of operating system for this too? Why? Mixed core CPU architectures Never heard of these. If possible please keep your answer in this format: XYZ CPU architectures Purpose of XYZ Need for a new architecture. why can't current microcomputer CPU architecture work? They go upto 3GHZ & have upto 8 cores. Need for a new Operating System Why do we need a new kind of operating system for this kind of archictures?

  • Application Does Not Start in Windows 7

    - by Jim Fell
    I recently installed a new 60GB SSD as my primary hard drive and re-installed Windows 7 Professional 64-bit. I then installed SSD Fresh from Abelssoft to optimize Windows to run on the SSD. It seemed to install okay, but when I try to run the utility, its splash screen appears briefly before it quietly closes. No errors are displayed; the utility just fails to launch. I have run SSD Fresh on another SSD-equipped Windows 7 Pro x64 computer in the past without any problems. Does anyone know what might be preventing the program from running? I tried running sfc /scannow from the command line (with administrator privileges), shutting down the Spybot Resident, and disabling the firewall and virus scanner. I also tried running the tool as administrator; I even tried reinstalling it, running the installer as administrator. No luck. Every time I try to launch the program the Event Viewer logs this same set of errors: Error 4/2/2012 11:35:44 PM Application Error 1000 (100) Faulting application name: SSDFresh.exe, version: 1.0.0.0, time stamp: 0x4f2a45d8 Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000 Exception code: 0xc0000005 Fault offset: 0x000007ff0016dbba Faulting process id: 0x994 Faulting application start time: 0x01cd11fd9fe978df Faulting application path: C:\Program Files (x86)\SSD Fresh\SSDFresh.exe Faulting module path: unknown Report Id: dfeed551-7df0-11e1-a2c7-002522c47ec0 Error 4/2/2012 11:35:43 PM .NET Runtime 1026 None Application: SSDFresh.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception.

  • How can I create a weekly calendar view for an Android Honeycomb application?

    - by BVB
    I am working on an Android (v3.0) application that has a requirement of mimicking the weekly calendar layout found on Google Calendar: The events will be based on external requests through the Google Calendar API (I already have this part working). Using the API, I can obtain a list of events for the week, with each event having a starting and and ending datetime. I would like to use this data to show the scheduled events to the application's users in a view similar to the one above. Here's what I have so far: The XML appears below: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="800dp" android:layout_height="match_parent" android:orientation="vertical" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content"

</RelativeLayout> </ScrollView> </LinearLayout> My approach was to make 40dp equal to 1 hr of time. Thus, whenever I would like to add an event that has a duration of 1.5 hours, I will make an 60dp button that I will place at the exact location that the time begins (12am = 0dp from the top, 1pm = 40dp from the top, 2pm = 80d from the top, etc). My questions are: Is there a better way of doing this? How can I convert my XML to be stand-alone view that could be added to any Android project? (I plan on perhaps making a blog post about the end product) Thank you!
