  • Bug Tracking Etiquete - Necromany or Duplicate?

    - by Shauna
    I came across a really old (2+ years) feature request issue in a bug tracker for an open source project that was marked as "resolved (won't fix)" due to the lack of tools required to make the requested enhancement, but since the determination was made, new tools have been developed that would allow it to be resolved, and I'd like to bring that to the attention of the community for that application. However, I'm not sure as to what the generally accepted etiquette is for bug tracking in cases like this. Obviously, if the system explicitly states to not duplicate and will actively mark new items as duplicates (much in the way the SE sites do), then the answer would be to follow what the system says. But what about when the system doesn't explicitly say that, or a new user can't easily find a place that says with the system's preference is? Is it generally considered better to err on the side of duplication or necromancy? Does this differ depending on whether it's a bug or a feature request?

  • Connecting / disconnecting DisplayPort causes crash

    - by iGadget
    I wanted to file a bug about this using ubuntu-bug xserver-xorg-video-intel, but the system prompted my to try posting here first. So here goes :-) While the situation in Ubuntu 11.10 was still somewhat workable (see UI freezes when disconnecting DisplayPort), in 12.04 (using Unity 3D) it has gotten worse. The weird part is that during the 12.04 beta's, the situation was actually improving! I was able to successfully connect and disconnect a DisplayPort monitor without the system breaking down on me. But now with 12.04 final (with all updates), it's just plain terrible. When I now connect an external monitor using the DisplayPort connector on my HP ProBook 6550b, it only works sometimes. Most times (but not always!) the screen just goes blank and the system seems to crash (not even CTRL+ALT+F1 works anymore). Only a hard shutdown by keeping the power button pressed for several seconds and then a restart gets me out of this. I suspect the chances of the system crashing become higher as the system's uptime increases, especially when there have been one or more suspend-resume cycles (although I have also experienced this bug once from a cold boot). Disconnecting is roughly the same as with 11.10 (see issue mentioned above), with the difference that if I resume from suspend, I no longer have to do a CTRL+ALT+F1, ALT+F7 cycle to get my screen back. So what more can I try? Or should I just go ahead and file the bug anyway?

  • Swap on Ubuntu: No primary partition

    - by 3l4ng
    I am running Ubuntu 13.10 64bit on a system with 4GB RAM, dual booting with Windows Most people say that it is good to have swap on a system, and results in speed, so I used it with my previous Ubuntu installations. In my new HDD, I use 3 primary partitions: 1 for Windows OS, 1 for Ubuntu and 1 for data. The windows system also took up one primary partition for system, and I have only 4 MBR slots. Effectively I have no primary partition for SWAP. I do not know it happened earlier, but back then I had a partition for swap as well My CURRENT disk partitioning looks like this: http://imgur.com/YMTr879 How can I create swap in my current setup?

  • Where are Outlook 2010 Email Settings, not the pst data files

    - by user64908
    I've found all my Outlook data files which contain all my emails at the following paths: C:\Users\C\AppData\Local\Microsoft\Outlook C:\Users\C\AppData\Roaming\Microsoft\Outlook and C:\Users\C\My Documents\Outlook Files\ I've migrated all these and copied it to my new machine at the same directories however my configuration is not there! None of my email pop/smtp settings are there, only the pst is loaded with my emails but all other configuration is gone, where precisely is that configuration stored?

  • Mutable Records in F#

    - by MarkPearl
    I’m loving my expert F# book – today I thought I would give a post on using mutable records as covered in Chapter 4 of Expert F#. So as they explain the simplest mutable data structures in F# are mutable records. The whole concept of things by default being immutable is a new one for me from my C# background. Anyhow… lets look at some C# code first. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace MutableRecords { public class DiscreteEventCounter { public int Total { get; set; } public int Positive { get; set; } public string Name { get; private set; } public DiscreteEventCounter(string name) { Name = name; } } class Program { private static void recordEvent(DiscreteEventCounter s, bool isPositive) { s.Total += 1; if (isPositive) s.Positive += 1; } private static void reportStatus (DiscreteEventCounter s) { Console.WriteLine("We have {0} {1} out of {2}", s.Positive, s.Name, s.Total); } static void Main(string[] args) { var longCounter = new DiscreteEventCounter("My Discrete Counter"); recordEvent(longCounter, true); recordEvent(longCounter, true); reportStatus(longCounter); Console.ReadLine(); } } } Quite simple, we have a class that has a few values. We instantiate an instance of the class and perform increments etc on the instance. Now lets look at an equivalent F# sample. namespace EncapsulationNS module Module1 = open System type DiscreteEventCounter = { mutable Total : int mutable Positive : int Name : string } let recordEvent (s: DiscreteEventCounter) isPositive = s.Total <- s.Total+1 if isPositive then s.Positive <- s.Positive+1 let reportStatus (s: DiscreteEventCounter) = printfn "We have %d %s out of %d" s.Positive s.Name s.Total let newCounter nm = { Total = 0; Positive = 0; Name = nm } // // Using it... // let longCounter = newCounter "My Discrete Counter" recordEvent longCounter (true) recordEvent longCounter (true) reportStatus longCounter System.Console.ReadLine() Notice in the type declaration of the DiscreteEventCounter we had to explicitly declare that the total and positive value holders were mutable. And that’s it – a very simple example of mutable types.

  • Configuring Team Foundation Server Basic on Home Server.

    - by Enrique Lima
    For the installation I selected only the Team Foundation Server role. Then, I opened the Team Foundation Server Administration Console (which I think is a great addition and improvement over the way TFS was configured in the past) to proceed with the configuration of the pieces. Once I selected the Configure Installed Features, the Configuration Center opened up. Now, the choices … In my implementation here I just want to take advantage of Source Control primarily.  I want to be able to store my code and projects.  So, Basic it is! So, the Basic Configuration Wizard opens up.  Now the options to configure are very limited, but we have to provide details for the SQL Server Instance. And now, to select Install SQL Server express.  If you want to take advantage of another system in your environment to host your database, well you could Use an existing SQL Server Instance. Once it has the details it needs, you get a Summary view to confirm your choices. Once, you click next or verify, it runs readiness checks on your system to make sure the installation will have a successful pass.  And we love GREEN! Now, since got the green flag, our next stop is to let the wizard do its magic, click on Configure.  And once again, we love GREEN! We click Next, and … We like a big Green Success sign … We close the Configuration Center … First results … Web Access …  Nothing to show … but we are there! And all this running from a Microsoft Home Server installation.

  • configure open_basedir under Plesk

    - by cori
    This might be a question for ServerFault, and if it wasn't for the Plesk aspect I would ask it there to start with, so if it's better suited for over there let me know and I'll move it. I'm working on a dedicated server set up as a reseller account with Plesk to manage the domains and server configuration, and I need to add a directory to the local open_basedir configuration for a specific vhost. Given Plesk's normal methodology, I expected to be able to go to /var/www/vhost/{%DOMAINNAME%}/conf and modify vhost.conf and place a new value there, as I have successfully done with other configuration settings for this domain (turning safe_mode off, for instance). When I do so, however, the new setting doesn't take (per phpinfo();). If I edit httpd.conf (which the plesk configuration specifically says not to do in the notes at the top of httpd.conf) the setting takes. Is there something specific about the open_basdir setting that makes it not configurable in vhost.conf? How much trouble am I letting myself in for by editing the vhost-specific httpd.conf (I imagine is someone makes changes in the plesk web interface it might be overwritten, but what other risk is there)? Thanks!

  • Configuring a MySQL 5.1 Instance on Windows 7 Professional x64 Fails

    - by Thomas Owens
    I'm trying to set up my laptops to function as mobile development environments. Installing the software on my Linux machine and getting it configured was fairly straightforward, however I'm having trouble getting MySQL 5.1 Server installed and configured on Windows 7 Professional 64-bit. I'm currently using the Windows MSI Installer for the complete MySQL 5.1 system (as opposed to the Essentials installer also available). I've tried to install using both the 32-bit and 64-bit versions of MySQL 5.1 - the same events occur in both. I've installed both the Server Instance Configuration Wizard and Workbench and everything appears to be installed just fine. When I open the Instance Configuration Wizard, I select Detailed Configuration. On the next screen, I select Development Environment, then Multifunctional Database on the next screen. I leave the InnoDB settings unchanged. I select Manual Setting with 5 concurrent connections. I enable TCP/IP Networking on Port 3306 and Enable Strict Mode. I select the Standard Character Set. I check the boxes for Install as a Windows Service (and provide the name "MySQL") and Include the Bin Directory in Windows PATH. On the next screen, I set my root user name and password. I do not enable root access from remote machines and I also do not create an anonymous account. On the final screen of the wizard, when I click "Execute", the first two tasks (Prepare Configuration and Write Configuration File) complete. However, when it reaches Start Service, the wizard hangs and becomes unresponsive ("Not Responding" appears in the title bar and Task Manager). I would really like to be able to use both my Windows and Linux laptops as full-blown mobile development environments, but I can't do that without being able to run MySQL. Has anyone encountered this problem before? What options do I have to correct it?

  • cannot add or remove programs using ubuntu software center (USC)in Kubuntu 12.04

    - by Suhail cholassery
    I am using Kubuntu 12.04,currently.Recently ,I updated my system with update manager and downloaded USC from muon software center which was pre-installed in this system. I could download a lot of softwares such as: -firefox -XBMC media center -VLC media player But when I tried to get some more softwares using USC, after rebooting there began the problem . It does not begin either downloading or instaling the program. When I tried to download the same program using muon software center it showed the following: Unable to obtain the package at this time Another application seems to be using the package system at this time. You must close all other package managers before you will be able to install or remove any packages. I am quite sure that have closed USC . I tried to remove USC, assuming that it caused the problem using muon software center but the result was same.Now I cannot add or remove any programs into my system & I don't know what to do . Please help me as soon as possible.

  • Image first loaded, then it isn't? (XNA)

    - by M0rgenstern
    I am very confused at the Moment. I have the following Class: (Just a part of the class): public class GUIWindow { #region Static Fields //The standard image for windows. public static IngameImage StandardBackgroundImage; #endregion } IngameImage is just one of my own classes, but actually it contains a Texture2D (and some other things). In another class I load a list of GUIButtons by deserializing a XML file. public static GUI Initializazion(string pXMLPath, ContentManager pConMan) { GUI myGUI = pConMan.Load<GUI>(pXMLPath); GUIWindow.StandardBackgroundImage = new IngameImage(pConMan.Load<Texture2D>(myGUI.WindowStandardBackgroundImagePath), Vector2.Zero, 1024, 600, 1, 0, Color.White, 1.0f, true, false, false); System.Console.WriteLine("Image loaded? " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); myGUI.Windows = pConMan.Load<List<GUIWindow>>(myGUI.GUIFormatXMLPath); System.Console.WriteLine("Windows loaded"); return myGUI; } Here this line: System.Console.WriteLine("Image loaded? " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); Prints "true". To load the GUIWindows I need an "empty" constructor, which looks like that: public GUIWindow() { Name = ""; Buttons = new List<Button>(); ImagePath = ""; System.Console.WriteLine("Image loaded? (In win) " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); //Image = new IngameImage(StandardBackgroundImage); //System.Console.WriteLine( //Image.IsActive = false; SelectedButton = null; IsActive = false; } As you can see, I commented lines out in the constructor. Because: Otherwise this would crash. Here the line System.Console.WriteLine("Image loaded? (In win) " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); Doesn't print anything, it just crashes with the following errormessage: Building content threw NullReferenceException: Object reference not set to an object instance. Why does this happen? Before the program wants to load the List, it prints "true". But in the constructor, so in the loading of the list it prints "false". Can anybody please tell me why this happens and how to fix it?

  • Get error (Repair Filesystem) 1 # when I install 4 new Hard drives in RedHat Linux 5 on a Dell PowerEdge 2900

    - by Alos Diallo
    Hi I am using a Dell PowerEdge 2900 running RedHat 5. I had 4 drives in the system using a Raid 5, I purchased and installed 4 more drives keeping the configuration the same. Set up the Vertual disks in PERC 6/i. When I exit out and reboot the system I get the following: fsck.ext3: No such file or dirrectory while trying open /dev/ddb1 [FAILED] ***An error occurred during the file system check. ***Dropping you to a shell; the system will reboot ***when you leave the shell. Then am prompted for the root pw. I enter it and am then prompted with: (Repair filesystem) 1# if I type fdisk -l I get some info on the disk along with: Disk /dev/sdb doesn't contain a valid partition table I am then prompted for (Repair filesystem) 2# If I reboot I am taken to the same screen again. The system was working before this happened. Does anyone know why this is happening and or what I can do to fix it? Thanks

  • What should I recommend a small company looking for C# developers

    - by Coder
    Here is the issue. I am a senior developer, and one of the start-ups I designed the system (management system/database/web) a long time ago, have grown and need software updates. I have left their system to another developer long time ago, but apparently he has left the job, and so they are asking me if I can suggest them where to find a new one. The problem is that the company has no clue that the IT is not cheap. They expect multiple features to be added for 40$, so that's an issue. Actually one of the reasons why I left the project when I did. Lots of expectations, little pay, also I know those people outside work, so I decided to avoided stressing the nonwork-relationships and left the project gracefully. Today they asked me for an advice, and I told them that the feature list they want is probably going to cost some if they'll get a senior developer for the job. So I guess their best bet is to find someone who loves coding and has just finished the school. Which would give someone a chance to code for money which is good for a student, and at the same time, allow the student to get some hands on experience. Then again, the system is not exactly 20 line console program, there is an MSSQL database, ASP.NET web page and content management system with all the AJAX stuff and some other things. So student straight out of school could have some problems with that. But, I thought about the issue some more, and I think that junior developer is a tricky deal, without mentoring, he can either screw up royally, or just do what's asked. Also, it seems no one is coming to interviews at all, which is weird, or maybe not. What should I suggest them?

  • How to explain bad software to non-technical people?

    - by mtutty
    In discussing software development with non-technical people (customers, business owners, project sponsors, etc.), I often resort to analogies and metaphors. It's relatively easy and effective to use a "house" or other metaphor for describing the size and complexity of new development. However, we often inherit someone else's code or data, and this approach doesn't seem to hold up as well when trying to explain why we're gutting something that already seems to work. Of course we can point to cycle time and cost to be saved in the future but this generally means nothing to business folks. I know doctors can say "just take this pill," but I'm not sure that software devs have the same authority. Ideas? EDIT: Let me add a bit to the discussion. The specific project I'm talking about has customers that don't realize (or care) about specific aspects of the system we're retiring (i.e., they think it was just fine): The system would save a NEW RECORD every time someone updated a field The system contained tables for reference data. These tables had new records added every day, even though they were duplicates of previous records. And there was no way to tie the reference data used for a particular case at the time it was closed. This is like 99% of the data in the old system. The field NAMES also have spaces, apostrophes and other inappropriate characters in them, making everything harder to work with. In addition to the incredible amount of duplicate data, they have around 1000 XLS files with data they want added to the system. Previously, they would do a spreadsheet for each case in the database, IN ADDITION TO what they typed into the database. Getting rid of this old, unneeded information and piping in the XLS data comprises about 80% of the total project effort, and was not something we could accurately predict. I'm trying to find a concrete way to describe how bad this thing was, mostly so that the customer will understand why the migration process has been so time-consuming. The actual coding was done pretty quickly and the new system works fine, but without the old data they won't be happy. Sorry to get into the weeds, but most of the answers I've seen so far are pretty basic scope/schedule/cost things. I've been doing this for 15 years, so this really is more of a reflective, philosophical question - but without some of the details it can be difficult to really appreciate the awful beauty of this problem.

  • How to customize the initrd embedded in or coming with the kernel image

    - by STATUS_ACCESS_DENIED
    I would like to add some tools and not just kernel modules into the initrd (initramfs-based). Now I'm aware of how to unpack and how to pack the initrd with cpio and have even written a hook for /etc/initramfs-tools/hooks in the past to integrate a third-party kernel module. However, while the available script libraries seem to be geared towards the integration of modules, none of them seems to be for integration of other entities (in particular programs and their dependencies). What options do I have to automate the integration of some useful tools for recovery into the initrd? I'm talking about the "rescue" system that the system drops into if it is unable to mount the root drive given to it by the boot loader. Please note that I don't want the SquashFS approach as is used for Live-CDs because for the issue at hand it will be by far sufficient to include some relatively small tools that aid in recovery of the system (when it gets stuck in initrd and can't boot further). Also, the machines when they run into the issue that we have had in the past tend to boot into the rescue system, but there a few tools are missing to kick the system back on trail ...

  • How to create a filesystem mountable by windows in linux?

    - by wcoenen
    I have attached an external USB disk to my debian gnu/linux system. The disk showed up as device /dev/sdc, and I prepared it like this: created a single partition with fdisk /dev/sdc (and some more commands in the interactive session that follows) formatted the partition with mkfs.msdos /dev/sdc1 If I then attach the USB disk to a Windows XP or Vista system, then no new drive becomes available. The disk and its partition show up fine in the disk managment tool under "computer management", but apparently the file system in the partition is not recognized. How do I create a FAT32 file system which can actually be used in windows? edit: I've given up on this and went with a NTFS file system created by windows. In debian lenny this can be mounted read-write but apparently it requires you to install the "ntfs-3g" package and explicitly pass the -t ntfs-3g option to the mount command.

  • Exiting a reboot loop

    - by user12617035
    If you're in a situation where the system is panic'ing during boot, you can use # boot net -s to regain control of your system. In my case, I'd added some diagnostic code to a (PCI) driver (that is used to boot the root filesystem). There was a bug in the driver, and each time during boot, the bug occurred, and so caused the system to panic: ... 000000000180b950 genunix:vfs_mountroot+60 (800, 200, 0, 185d400, 1883000, 18aec00) %l0-3: 0000000000001770 0000000000000640 0000000001814000 00000000000008fc %l4-7: 0000000001833c00 00000000018b1000 0000000000000600 0000000000000200 000000000180ba10 genunix:main+98 (18141a0, 1013800, 18362c0, 18ab800, 180e000, 1814000) %l0-3: 0000000070002000 0000000000000001 000000000180c000 000000000180e000 %l4-7: 0000000000000001 0000000001074800 0000000000000060 0000000000000000 skipping system dump - no dump device configured rebooting...

However, we are using boot net -s as a "handle" with which to get at the Solaris prompt. Once at that prompt, we can perform actions as root that will let us back out our buggy driver (ok...

  • How to prevent Network Manager from auto creating network connection profiles with "available to everyone" by default

    - by airtonix
    We have several laptops at work which use Ubuntu 11.10 64bit. I have our Wifi Access Point requiring WPA2-EAP Authentication (backed by a LDAP server). I have the staff using these laptops when doing presentations by using the Guest Account. So by default when you have a wifi card, network manager will display available Wireless Access Points. So the logical course of action for a Novice(tm) user is to single left click the easy to use option in the Network Manager drop down list... At this point the Staff Member (who is logged in with the guest account) expects to just be able to connect and enter any authentication details if required. But because they are using the Guest account, they won't ever have admin permissions (nor do I want them to), and so PolKit kicks in with a request for admin authorisation. I solved this part by modifying the PolKit permissions required to allow all users to create System Network Connections... However, because these Staff members are logging onto the Wifi Access Point with Ldap Credentials and because the Network Manager is now saving those credentials as a System Connection, their password is available for the next guest user session (because system connection profiles are stored in /etc/NetworkManager/system-connections.d/* ). It creates system connections by default because "Available to all users" is ticked by default when you quickly connect to a new wifi access point. I want Network Manager to not tick this by default. This way I can revert the changes I made to Polkit and users network connection profiles will be purged when they log out.

  • Apache won't accept external requests

    - by Eric
    I am running Apache 2.2 on windows and I would like to access it remotely. Currently I can only access it from my local machine. I know the problem is not port forwarding because I tested it with other web servers (written in python). My httpd.conf file is below. I installed apache with the PHP installer. # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "logs/foo.log" # with ServerRoot set to "C:/Program Files (x86)/Apache Software Foundation/Apache2.2" will be interpreted by the # server as "C:/Program Files (x86)/Apache Software Foundation/Apache2.2/logs/foo.log". # # NOTE: Where filenames are specified, you must use forward slashes # instead of backslashes (e.g., "c:/apache" instead of "c:\apache"). # If a drive letter is omitted, the drive on which httpd.exe is located # will be used by default. It is recommended that you always supply # an explicit drive letter in absolute paths to avoid confusion. # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to point the LockFile directive # at a local disk. If you wish to share the same ServerRoot for multiple # httpd daemons, you will need to change at least LockFile and PidFile. # ServerRoot "C:/Program Files (x86)/Apache Software Foundation/Apache2.2" # # Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default. See also the <VirtualHost> # directive. # # Change this to Listen on specific IP addresses as shown below to # prevent Apache from glomming onto all bound IP addresses. # #Listen 12.34.56.78:80 Listen 80 # # Dynamic Shared Object (DSO) Support # # To be able to use the functionality of a module which was built as a DSO you # have to place corresponding `LoadModule' lines at this location so the # directives contained in it are actually available _before_ they are used. # Statically compiled modules (those listed by `httpd -l') do not need # to be loaded here. # # Example: # LoadModule foo_module modules/mod_foo.so # LoadModule actions_module modules/mod_actions.so LoadModule alias_module modules/mod_alias.so LoadModule asis_module modules/mod_asis.so LoadModule auth_basic_module modules/mod_auth_basic.so #LoadModule auth_digest_module modules/mod_auth_digest.so #LoadModule authn_alias_module modules/mod_authn_alias.so #LoadModule authn_anon_module modules/mod_authn_anon.so #LoadModule authn_dbd_module modules/mod_authn_dbd.so #LoadModule authn_dbm_module modules/mod_authn_dbm.so LoadModule authn_default_module modules/mod_authn_default.so LoadModule authn_file_module modules/mod_authn_file.so #LoadModule authnz_ldap_module modules/mod_authnz_ldap.so #LoadModule authz_dbm_module modules/mod_authz_dbm.so LoadModule authz_default_module modules/mod_authz_default.so LoadModule authz_groupfile_module modules/mod_authz_groupfile.so LoadModule authz_host_module modules/mod_authz_host.so #LoadModule authz_owner_module modules/mod_authz_owner.so LoadModule authz_user_module modules/mod_authz_user.so LoadModule autoindex_module modules/mod_autoindex.so #LoadModule cache_module modules/mod_cache.so #LoadModule cern_meta_module modules/mod_cern_meta.so LoadModule cgi_module modules/mod_cgi.so #LoadModule charset_lite_module modules/mod_charset_lite.so #LoadModule dav_module modules/mod_dav.so #LoadModule dav_fs_module modules/mod_dav_fs.so #LoadModule dav_lock_module modules/mod_dav_lock.so #LoadModule dbd_module modules/mod_dbd.so #LoadModule deflate_module modules/mod_deflate.so LoadModule dir_module modules/mod_dir.so #LoadModule disk_cache_module modules/mod_disk_cache.so #LoadModule dumpio_module modules/mod_dumpio.so LoadModule env_module modules/mod_env.so #LoadModule expires_module modules/mod_expires.so #LoadModule ext_filter_module modules/mod_ext_filter.so #LoadModule file_cache_module modules/mod_file_cache.so #LoadModule filter_module modules/mod_filter.so #LoadModule headers_module modules/mod_headers.so #LoadModule ident_module modules/mod_ident.so #LoadModule imagemap_module modules/mod_imagemap.so LoadModule include_module modules/mod_include.so LoadModule info_module modules/mod_info.so LoadModule isapi_module modules/mod_isapi.so #LoadModule ldap_module modules/mod_ldap.so #LoadModule logio_module modules/mod_logio.so LoadModule log_config_module modules/mod_log_config.so #LoadModule log_forensic_module modules/mod_log_forensic.so #LoadModule mem_cache_module modules/mod_mem_cache.so LoadModule mime_module modules/mod_mime.so #LoadModule mime_magic_module modules/mod_mime_magic.so LoadModule negotiation_module modules/mod_negotiation.so #LoadModule proxy_module modules/mod_proxy.so #LoadModule proxy_ajp_module modules/mod_proxy_ajp.so #LoadModule proxy_balancer_module modules/mod_proxy_balancer.so #LoadModule proxy_connect_module modules/mod_proxy_connect.so #LoadModule proxy_ftp_module modules/mod_proxy_ftp.so #LoadModule proxy_http_module modules/mod_proxy_http.so #LoadModule reqtimeout_module modules/mod_reqtimeout.so #LoadModule rewrite_module modules/mod_rewrite.so LoadModule setenvif_module modules/mod_setenvif.so #LoadModule speling_module modules/mod_speling.so #LoadModule ssl_module modules/mod_ssl.so LoadModule status_module modules/mod_status.so #LoadModule substitute_module modules/mod_substitute.so #LoadModule unique_id_module modules/mod_unique_id.so #LoadModule userdir_module modules/mod_userdir.so #LoadModule usertrack_module modules/mod_usertrack.so #LoadModule version_module modules/mod_version.so #LoadModule vhost_alias_module modules/mod_vhost_alias.so #LoadModule php5_module "c:/php/php5apache2_2.dll" <IfModule !mpm_netware_module> <IfModule !mpm_winnt_module> # # If you wish httpd to run as a different user or group, you must run # httpd as root initially and it will switch. # # User/Group: The name (or #number) of the user/group to run httpd as. # It is usually good practice to create a dedicated user and group for # running httpd, as with most system services. # User daemon Group daemon </IfModule> </IfModule> # 'Main' server configuration # # The directives in this section set up the values used by the 'main' # server, which responds to any requests that aren't handled by a # <VirtualHost> definition.

  • How to know how much detailed requirements should be?

    - by user1620696
    This doubt has to do with the requirements gathering phase of each iteration in one project based on agile methodologies. It arose because of the following situation: suppose I meet with my customer to gather the requirements and he says something like: "I need to be able to add, edit, remove and see details of my employees". That's fine, but how should we register this requirement? Should we simply write something like "the system must allow the user to manage employees", or should we be more specific writing for points The system must allow the user to add employees; The system must allow the user to see details of employees; The system must allow the user to edit employees; The system must allow the user to delete employees; Of course, this is just an example of a situation I was in doubt. The main point here is: how to know how much detailed I must be, and how to know what I should register? Are there strategies for dealing with these things? Thanks very much in advance!

  • apt - Remove not configured package

    I have a Linux-Mint Debian Edition System. When I install sendmail I get an infinite loop. Reading configuration from /etc/mail/sendmail.conf. Validating configuration. Creating /etc/mail/databases... Reading configuration from /etc/mail/sendmail.conf. Validating configuration. Creating /etc/mail/databases... When I try dpkg --configure -a it is the same. Now I want to simple remove sendmail from the installation queue - but I can't simply do that, because apt-get always wants to configure sendmail first. Is there a way to force apt-get to remove sendmail or set it to "configured" - even though the package is not properly configured?

  • solaris + EMC + power-path

    - by yael
    please advice - when I run powercf command on my Solaris machine , which changes this command do on the EMC storage , or on Solaris file system ? from maanual page: DESCRIPTION During system boot on Solaris hosts, the powercf utility configures PowerPath devices by scanning the HBAs for both single-ported and multiported storage system logical dev- ices. (A multiported logical device shows up on two or more HBAs with the same storage system subsystem/device identity. The identity comes from the serial number for the logical device.) For each storage system logical device found in the scan of the HBAs, powercf creates a corresponding emcpower device entry in the emcp.conf file, and it saves a primary path and an alternate primary path to that device.

  • Reasons behind polymorphism related behaviour in java

    - by Shades88
    I read this code somewhere class Foo { public int a; public Foo() { a = 3; } public void addFive() { a += 5; } public int getA() { System.out.println("we are here in base class!"); return a; } } public class Polymorphism extends Foo{ public int a; public Poylmorphism() { a = 5; } public void addFive() { System.out.println("we are here !" + a); a += 5; } public int getA() { System.out.println("we are here in sub class!"); return a; } public static void main(String [] main) { Foo f = new Polymorphism(); f.addFive(); System.out.println(f.getA()); // SOP 1 System.out.println(f.a); // SOP 2 } } For SOP1 we get answer 10 and for SOP2 we get answer 3. Reason for this is that you can't override variables whereas you can do so for methods. This happens because type of the reference variable is checked when a variable is accessed and type of the object is checked when a method is accessed. But I am wondering, just why is it that way? Can anyone explain me what is the reason for this behaviour
