  • Why does CPU processing time matter when compared to real wall clock time?

    - by PeanutsMonkey
    I am running the command time 7zr a -mx=9 sample.7z sample.log to gauge how long it takes to compress a file larger than 1GB. The results I get are as follows. real 10m40.156s user 17m38.862s sys 0m5.944s I have a basic understanding of the difference but don't understand how this plays a role in the time in takes to compress the file. For example should I be looking at real or user + sys?

  • Write a program that allows the user to enter a string and then prints the letters of the String sep

    - by WM
    The output is always a String, for example H,E,L,L,O,. How could I limit the commas? I want the commas only between letters, for example H,E,L,L,O. import java.util.Scanner; import java.lang.String; public class forLoop { public static void main(String[] args) { Scanner Scan = new Scanner(System.in); System.out.print("Enter a string: "); String Str1 = Scan.next(); String newString=""; String Str2 =""; for (int i=0; i < Str1.length(); i++) { newString = Str1.charAt(i) + ","; Str2 = Str2 + newString; } System.out.print(Str2); } }

  • C#.NET How to access fields in user control dynamically?

    - by Conor H
    Hi, I'm making a settings screen at the moment that will have a radiobutton group which will determine what controls are displayed. The different settings are contained within a UserControl. I am dynamically creating this UserControl like so: panel = new btSettings(); this.Controls.Add(panel); panel.Location = new Point(15, 49); Just wondering how I can access the fields within this control and design time when the object will only be created during run time? Thanks.

  • On demand upload server

    - by stimms
    I'm looking for a simple application which will do something like Allow user to sign up for an ftp account -> ask admin for approval -> create ftp account for that user now it doesn't have to be FTP, in fact I would be happy with a web based tool which supported upload via some sort of java applet or something similar. I don't care about what platform it runs on, although if we could avoid PHP that would be cool. Any ideas?

  • Is there a semi-standard way to associate a URL with an IRC user?

    - by DRMacIver
    I'm in the process of doing some identity consolidation, so I'm providing URLs to me at various locations on the internet. I'm quite active on IRC, so this naturally lead me to wonder whether there was a way to provide a link to my IRC presence. This lead to me finding http://www.w3.org/Addressing/draft-mirashi-url-irc-01.txt which appears to be a draft of an RFC for associating URLs with IRC, which suggests that I would be irc://irc.freenode.net/DRMacIver,isnick Which seems a little on the lame side. Further, this RFC draft has very thoroughly expired (February 28 1997). On the other hand it seems to be implemented in chatzilla at least: http://www.mozilla.org/projects/rt-messaging/chatzilla/irc-urls.html So does anyone know if there's a superseding RFC and/or any other de facto standard for this?

  • browser cookie issue

    - by George2
    Hello everyone, In my previous understanding, for a web site, only login user of a web site (no matter what login/authentication approach is used) could have cookie as persistent identifier, so that if the user close the browser, open browser again to go to the same web site, the web site could remember the user. But I learned recently that it seems for non-login user, there could still be a cookie associated with the user (after the user close browser, and then open the browser again to go to the same web site, the web site could remember the user), and it is called browser cookie? Is that true? If it is true, who is responsible to set the browser cookie? i.e. need some coding/config at web server side, client browser configuration (without coding from server side), or both? How could web server access such cookie? Appreciate if any code samples. thanks in advance, George

  • Windows powering off after "preparing your desktop" stage.

    - by Jack
    Windows 7 64 bit. The only recent change was I installed two updates for MS Office, and a cumulative security update for IE. As soon as I choose a user and login, after loading my user profile it states the preparing your desktop message, and then powers off. I have used DaRT to check the event log, but nothing is recorded. Ideas?

  • How to make a remote connection to a MySQL Database Server?

    - by MLB
    Hello: I am trying to connect to a MySQL database server (remote), but I can't. I am using an user with grant privileges (not root user). The error message is the following: Can't obtain database list from the server. Access denied for user 'myuser'@'mypcname' (using password: YES) "myuser" is an user I created with grant access. This user allows me to connect locally to every database. I am using the same software versions in both hosts: MySQL Server 4.1 (server) and EMS SQL Manager 2005 for MySQL, edition 3.7.0.1 (client). The point is that I need to connect to the remote server using a different user, not root user. So, how to make the connection? Thanks.

  • Partial form with nested routes

    - by jerhinesmith
    I have two models -- User and Entry -- that are related through a has_many relationship (a User has many Entries). I'm using RESTful routing, and have the following in my routes.rb file: map.resource :user, :controller => "users" do |user| user.resources :entries end This seems to work, but in my partial _form file, when I do this: form_for [@current_user, @entry] do |f| # Form stuff end It generates a URL like this: /user/entries.%23%3Cuser:0xb6a6aea8%3E instead of /user/entries Am I missing something? I should note that the correct classes are applied to the form when doing creation vs. editing, so it does seem to be correctly interpreting what I'm trying to do -- it's just that I can't submit the form to an invalid url.

  • Is there a way to achieve covariance of generic types in C# 3.0?

    - by nullDev
    This has been introduced in C# 4.0, but is there a way to achieve this in c# 3.0? For e.g., consider the following code: class Base { } class Derived1 : Base { } class Derived2 : Base { } class User<T> where T : Base { } class User1 : User<Derived1> { } Now, I would like to have a list of User<T>, in which I can store User<Derived1> as well as User<Derived2>, but the following code fails to compile in C# 3.0: List<User<Base>> users = new List<User<Base>>(); users.Add(new User1()); Any ideas?

  • Why assign write and execute permissions to a group when executing web scripts?

    - by PeanutsMonkey
    If I have a script that is to be executed by the nobody user, why is there a need to assign group write and execute permissions. For example in the article at http://www.zzee.com/solutions/unix-permissions.shtml, it notes that the permission 755 should be assigned to scripts on a web server. I understand that the user nobody is treated as others and as the owner of the script I would like full permissions. Am I missing something?

    Hello, is it possible to remove a user's password using the net command? I tried "net user *" and just hitting return twice, but this does not work as expected. Is there any other way to do this? (I'd gladly take non-net commands, as long as they are built-in in XP SP3) Best regards, MB
