Ubuntu 9.10 x86_32 with PAE causes graphics issues, mainly slowness

- by widgisoft

I've tried the 64bit version and found I was constantly hitting a brick wall trying to get 32bit stuff to run; I'd previously used PAE on 9.04 without any issues so figured I'd give it a shot. However, on 9.10 it seems PAE or the process of enabling PAE breaks the nvidia drivers/module somewhat as performance is terrible; I can't even enable desktop effects and there's lots of artifacting on random controls. Disabling the pae image and rebooting fixes the issue however I'm then stuck with "only" 2.7Gb of ram and unable to use the full 8gb that's installed. Is there somthing special I need to do when using pae and nVidia drivers or should I be using 64bit and just figure out how to force run 32bit packages? :-p

Overriding Object.Equals() instance method in C#; now Code Analysis / FxCop warning CA2218: "should

- by Chris W. Rea

I've got a complex class in my C# project on which I want to be able to do equality tests. It is not a trivial class; it contains a variety of scalar properties as well as references to other objects and collections (e.g. IDictionary). For what it's worth, my class is sealed. To enable a performance optimization elsewhere in my system (an optimization that avoids a costly network round-trip), I need to be able to compare instances of these objects to each other for equality – other than the built-in reference equality – and so I'm overriding the Object.Equals() instance method. However, now that I've done that, Visual Studio 2008's Code Analysis a.k.a. FxCop, which I keep enabled by default, is raising the following warning: warning : CA2218 : Microsoft.Usage : Since 'MySuperDuperClass' redefines Equals, it should also redefine GetHashCode. I think I understand the rationale for this warning: If I am going to be using such objects as the key in a collection, the hash code is important. i.e. see this question. However, I am not going to be using these objects as the key in a collection. Ever. Feeling justified to suppress the warning, I looked up code CA2218 in the MSDN documentation to get the full name of the warning so I could apply a SuppressMessage attribute to my class as follows: [SuppressMessage("Microsoft.Naming", "CA2218:OverrideGetHashCodeOnOverridingEquals", Justification="This class is not to be used as key in a hashtable.")] However, while reading further, I noticed the following: How to Fix Violations To fix a violation of this rule, provide an implementation of GetHashCode. For a pair of objects of the same type, you must ensure that the implementation returns the same value if your implementation of Equals returns true for the pair. When to Suppress Warnings ----- Do not suppress a warning from this rule. [arrow & emphasis mine] So, I'd like to know: Why shouldn't I suppress this warning as I was planning to? Doesn't my case warrant suppression? I don't want to code up an implementation of GetHashCode() for this object that will never get called, since my object will never be the key in a collection. If I wanted to be pedantic, instead of suppressing, would it be more reasonable for me to override GetHashCode() with an implementation that throws a NotImplementedException? Update: I just looked this subject up again in Bill Wagner's good book Effective C#, and he states in "Item 10: Understand the Pitfalls of GetHashCode()": If you're defining a type that won't ever be used as the key in a container, this won't matter. Types that represent window controls, web page controls, or database connections are unlikely to be used as keys in a collection. In those cases, do nothing. All reference types will have a hash code that is correct, even if it is very inefficient. [...] In most types that you create, the best approach is to avoid the existence of GetHashCode() entirely. ... that's where I originally got this idea that I need not be concerned about GetHashCode() always.

How to remove ActiveX Add on from IE 7 (normal method does not work)

- by James

Hi, Does anybody know how to remove an ActiveX control from Internet Explorer 7.0 ? I had been deleting and adding this control numerous times using the built in delete button in Tools, Manage Add-ons, Enable or Disable. This is required for me to test a downloader ActiveX used for a website. It had always shown up in the "Downloaded ActiveX Controls (32 bit) section of the drop down which activates the delete button. However, all of a sudden it now appears under "Add ons that have been used by Internet Explorer" and I cannot delete it from there. The "in folder" column says it's in the C:\WINDOWS\Downloaded Program Files folder... But it does not appear to be there either... Thanks, James

Dell SC1435 always requires F1 at boot

- by David Mackintosh

I have a Dell PowerEdge SC1435 that has come back after doing duty at a partner site. I am trying to configure it for local use. The only problem I have with it is that every time it boots it always requres a manual F1 press after the POST sequence. The last thing it does is give me the opportunity to configure the BMC, and then it says: Press F1 to continue or press F2 for Setup It will wait there forever (well, at least an hour). Pressing F1 starts the OS booting. I can't see the setting in the BIOS which controls this and I can't find it in the documentation. What am I missing?

SRSS Client Print Module must be downloaded every use

- by Jmcgee73

I am currently having an issue with SQL Server Reporting Services. Everytime a user clicks the print button for the report, the user must install the ActiveX client print module. The issue is that our clients are not admins on their computers. So therefore they can not install the module. I have gotten around this roughly by adding the SQL address to trust sites, setting "Download signed Active Controls" to enable, and then giving the users permission to write to "C:\Windows\Downloaded Program Files". However, this is fix is not easy to distrubute to our user base. I am using SQL Server 2008 SP3 CU3 running on Server 2008 R2. I believe the browser thinks the version is newer than what is on the server. I have tried downloading the print module CAB file from the SQL server and installing manually. That did not work either. Thanks!

Disable Mailman Reminders

- by VxJasonxV

We run a mailserver on OSX server, and a few mailing lists. The password/subscription reminds USED to come out at 8AM (local), but in the past months it's moved to 5AM, a nuisance to all involved. It would appear that mailman has been modified by Apple because there is no cronjob entry I can find that controls when these reminder notices come out, and I haven't found any launch agent/daemon plists that would control this ether. Nor have I found anything in the mailman configuration web pages. So... where are they?! Due to the specific-announcement style of use, they're a fairly worthless message to be originated, and they are a huge bother when announcing to support phones.

- by ProfessionalAmateur

Trying to install a fresh install of Sharepoint 2010 (w/ SP1) and SQL Server 2012 PowerPivot for Sharepoint. The prerequisites clearly show that Sharepoint 2010 SP1 is needed, which we have installed. However after when trying to install the SQL Server portion we consistently fail the rule SharePoint version requirement for PowerPivot for SharePoint' validation in theSQL Server` install process. Here is the process we are following: 1. install Sharepoint 2010 2. install Sharepoint 2010 SP1 3. install SQL Server 2012 PowerPivot for SharePoint Here is a screen shot of the error and the log file error. We are completely stuck at this point, anyone run into this before?

What options can I use in totem, xine or vlc to play on machines with limited resources?

- by Nina

Mplayer has some options that allow me to play it on a machine with limited resources. I can use mplayer -vo x11 -zoom -framedrop to play videos when otherwise I'd run out of memory. At least I think I'm running out of memory. I am running our of some resource for sure. -vo sets the video output driver -zoom actually I don't know what this does, but it works for me ;-) -framedrop allows mplayer to not render frames if it falls behind. Are there similar command line controls (or a defaults file) for totem, vlc or xine?

Java works under Firefox but crashes Internet Explorer

- by Dominic Grenier

Java works under Firefox and Chrome but not under IE. Here's what I tried (the advice normally given on forums): Java applet activated in tools - internet options - security tab - personnalise - Java applets Activated in tools - manage add-ons - tool bars and extensions - Java (tm) SSV2 helper - Activate Activated in tools - internet options - advanced tab - Use JRE for applet I've also deleted my temporary internet files (with Ccleaner), Reinstalled IE8 It is also set as the default Java for IE through the control panel - Java - Advanced tab - default Java for browsers - Microsoft Internet Explorer IE version: 8.0.6001.18702 Java version: 1.7.0_03. (also tried with 1.6.0_31) Windows XP SP3. Any advice? Thanks :) edit: I have activated the ActiveX controls through manage add-ons - all add-ons but now, although the coffe cup loading screen appears (which did not before) it makes IE crash (which is new). I might have fiddled too much with the registry by trying to completely remove Java to reinstall it, so I ran "rereg" (a tool to repair dlls and their registry entries) without success.

Alsa hardware volume with PulseAudio

- by Jan Hudec

Before installing pulseaudio, I was able to control volume for the front (meaning on the front panel, the "headphone" jack) and rear (meaning on the back panel, the "line out" jack) separately. When I installed pulseaudio, it became possible to control volume for each playing process separately, but the individual controls for outputs disappeared. While the default device in alsa now routes via pulseaudio, the sysdefault device provides access to the hardware. But kmix does not seem to let me show them now. Is there any way to beat kmix into showing the sysdefault device too? Or something else X-based that would not fight with kmix too much? The system is Debian Jessie (testing) amd64, updated, KDE version 4:4.13.3-1.

selinux permissive and type targeted

- by krisdigitx

i am running centos 6.2 recently i noticed that apache was running with selinux enabled # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=Permissive # SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted i noticed that these errors were coming on dmesg type=1400 audit(1354453732.704:9056368): avc: denied { name_connect } for pid=39006 comm="httpd" dest=11211 scontext=unconfined_u:system_r:httpd_t:s0 tcontext=system_u:object_r:memcache_port_t:s0 tclass=tcp_socket type=1400 audit(1354453735.777:9056369): avc: denied { name_connect } for pid=39046 comm="httpd" dest=6379 scontext=unconfined_u:system_r:httpd_t:s0 tcontext=system_u:object_r:port_t:s0 tclass=tcp_socket i then enabled /usr/sbin/setsebool httpd_can_network_connect=1 and this stopped the errors and also the webpages started to work. My question is if selinux is in permissive mode will selinuxtype=targeted enforce any polices? if not how did it solve the problem with apache as selinux was already in permissive mode?

Why only one video shows up in ASP.NET Video panel ?

It is possible to have multiple videos with Flowplayer http://flowplayer.org/demos/installation/multiple-players.html To do so in ASP.NET DYNAMICALLY, one has to use a Panel (see http://idevwebs.com/Default.aspx?id=25): <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head>   <script type="text/javascript" src="flowplayer-3.1.4.min.js"></script>  <title>Minimal Flowplayer setup</title> </head><body> <form id="form1" runat="server"> <div id="page"> <h1>Minimal Flowplayer setup</h1> <p>View commented source code to get familiar with Flowplayer installation.</p>   <asp:Panel ID="panelVideo" runat="server"> </asp:Panel>  <script type="text/javascript"> flowplayer("player", "flowplayer-3.1.5.swf"); </script>  <p> If you are running these examples <strong>locally</strong> and not on some webserver you must edit your <a href="http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.html"> Flash security settings</a>. </p> <p class="less"> Select "Edit locations" > "Add location" > "Browse for files" and select flowplayer-x.x.x.swf you just downloaded. </p> <h2>Documentation</h2> <p> <a href="http://flowplayer.org/documentation/installation/index.html">Flowplayer installation</a> </p> <p> <a href="http://flowplayer.org/documentation/configuration/index.html">Flowplayer configuration</a> </p> <p> See this identical page on <a href="http://flowplayer.org/demos/example/index.htm">Flowplayer website</a> </p> </div> </form> </body></html> and then add video anchor dynamically public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { this.panelVideo.Controls.Add(new LiteralControl("<a href=\"" + "http://blip.tv/file/get/" + "KimAronson-TwentySeconds58192" + ".flv\" style=\"display:block;width:388px;height:230px\" id=\"player\"></a>")); this.panelVideo.Controls.Add(new LiteralControl("<a href=\"" + "http://blip.tv/file/get/" + "KimAronson-TwentySeconds67463" + ".flv\" style=\"display:block;width:388px;height:230px\" id=\"player\"></a>")); } } But it works only partially as the first video shows up not both.

Error using Session in IIS7

- by flashnik

After deployment of my website to IIS I'm getting a following error message when trying to access session: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration. I access it in Page_Load or PreRender events (I tried both versions). With VS Dev Server it works without a problem. I tried both InProc an SessionState storage, 1 and multiple woker processes. I added a enableSessionState = "true" to my webpage explicitly.

Is there a lightweight MTA for Ubuntu 9.10 Desktop?

- by Joe Casadonte

I'm writing a Perl script to run as a cron job, and I want to email results & errors to a local account on the laptop. I'd like something that can talk SMTP (do any MTAs not adhere to SMTP?). I use Thunderbird 3, so I'll also need a POP/IMAP server (unless T-Bird can read straight from an mbox file; I'll have to check into that). No need for spam controls as I'll lock it down real tight, only accepting mail originating from the laptop itself. Thanks!

How to make VLC show single FLAC file containing many tracks as separate tracks

- by Bryce Thomas

I have a single .flac file that encompasses multiple tracks comprising a music album along with the corresponding .cue file. I'm running Ubuntu 10.04 with VLC player, and am trying to get VLC player to show the individual tracks and allow me to use the previous and next controls to move back and forth between tracks. The problem I'm having is that when I open the single .flac file with VLC, it just shows a single track the duration of the entire album, and I'm unable to skip back and forth between tracks. Is there any way to have VLC show the individual tracks contained within a .flac file without having to pre-split the .flac file into individual track files first?

Is there a way to change the date format used when InfoPath saves the form data to xml?

- by Robert

I have an InfoPath Form template that has some Date Picker controls in it bound to elements in an xml data source. I know I can change the display format of the date by going into the Date Picker Properties and setting the date format. This foramt is only used for display puposes when the form is being filled out. When the form is saved as an xml file the date is always stored in the format YYYY-MM-DD. Is there a way to change the date format that gets serialized to xml? I'm using InfoPath 2007.

A different interface for the Sql Server Reporting Service?

- by AngryHacker

I have a SQL Server 2005 SQL Reporting Services implementation. It seems that the only way to actually access the reports is for the users to use Internet Explorer. The web page uses an ActiveX control to do its printing (and probably other functions as well). Does SSRS have a different way to access its functionality via the web browser? Like maybe Java or HTML based? If so, how do I actually turn it on? The reason I am asking is because the security is being tightened and ActiveX controls will be banished, thus the users won't be able to print.

Bootcamp's "Use all F1, F2, etc. keys" switches back automatically

- by cheeesus

I use Windows 7 in a Bootcamp partition on my iMac. I always check the option "Use all F1, F2, etc. keys as standard function keys", and when it's checked, everything works great. But recently, something switches this setting back to 'unchecked' every few minutes. I constantly have to open the Boot Camp Control Panel, uncheck the checkbox, check it again and click on 'Apply'. And five minutes later, the F2 key again controls the brightness of the screen and not the renaming of files in Explorer. This is driving me mad. What could be the cause of this? Is there a keystroke to switch this feature?

Create Virtual Image of Laptop before Formatting

- by Simon Mark Smith

I have a 3 year old laptop running Windows XP that I used for business. Although I have not used the laptop in over a year, I now want to re-commission it with Windows 7 and a fresh install. Before I do the fresh install I want to create a Virtual Image of the laptop that I can keep and potentially run on my desktop machine should I ever need to access any of the old files/projects that it contains currently. I know that most people will say just copy the files over to your desktop, but my concern is the configuration of the laptop. I used to use it for development and it has older versions of Visual Studio, SQL Server, Active X controls etc, etc than I currently use so I really want to preserve the environment not just the files. So really I am asking what is the best tool-set/method to achieve this? I understand there are free VM tools available but I have never done this before and would appreciate any help.

Transfer nearly an entire file system to a fresh install as smoothly as possible

- by Xander

I've got a friend who needs his computer working in just a few hours. His files are safe, however, he managed to corrupt his main install of Windows 7. My plan is to go in with a Linux disk, copy his C:\ do a backup drive I've got and then reinstall. Restoring many of his files will be pretty simple (such as documents and such), however, things such as applications won't transfer as easily. Is there any easy way to transfer applications such as MS Office (which he needs in the morning) or other commercial software packages without having to go through the hassle of locating the keys and reinstalling them completely? I don't think just moving them over will work just because of the fact that I'm sure much of that is stored in the registry (validation stuff and such). Anyways, quick responses would be super nice! Also, additional help would be great!

Help Repainting a Line

- by serhio

I am doing a custom control (inherited from VisualBasic.PowerPacks.LineShape), that should be painted like as standard one, but also having a Icon displayed near it. So, I just overrided OnPaint like this: protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { e.Graphics.DrawIcon(myIcon, StartPoint.X, StartPoint.Y); base.OnPaint(e); } Now, everything is OK, but when my control moves, the icon still remains drawn on the ancient place. Is there a way to paint it properly? The sample code for tests using Microsoft.VisualBasic.PowerPacks; using System.Windows.Forms; using System.Drawing; namespace LineShapeTest { /// /// Test Form /// public class Form1 : Form { IconLineShape myLine = new IconLineShape(); ShapeContainer shapeContainer1 = new ShapeContainer(); Panel panel1 = new Panel(); public Form1() { this.panel1.Dock = DockStyle.Fill; // load your back image here this.panel1.BackgroundImage = global::WindowsApplication22.Properties.Resources._13820t; this.panel1.Controls.Add(shapeContainer1); this.myLine.StartPoint = new Point(20, 30); this.myLine.EndPoint = new Point(80, 120); this.myLine.Parent = this.shapeContainer1; MouseEventHandler panelMouseMove = new MouseEventHandler(this.panel1_MouseMove); this.panel1.MouseMove += panelMouseMove; this.shapeContainer1.MouseMove += panelMouseMove; this.Controls.Add(panel1); } private void panel1_MouseMove(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { myLine.StartPoint = e.Location; } } } /// /// Test LineShape /// public class IconLineShape : LineShape { Icon myIcon = SystemIcons.Exclamation; protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { e.Graphics.DrawIcon(myIcon, StartPoint.X, StartPoint.Y); base.OnPaint(e); } } } Nota Bene, for the lineShape: Parent = ShapeContainer Parent.Parent = Panel Update 1 TRACES In this variant of OnPaint, we have traces: protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { Graphics g = Parent.Parent.CreateGraphics(); g.DrawIcon(myIcon, StartPoint.X, StartPoint.Y); base.OnPaint(e); } Update 2 BLINKS In this variant of OnPaint, we have a blinking image: protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { Parent.Parent.Invalidate(this.Region, true); Graphics g = Parent.Parent.CreateGraphics(); g.DrawIcon(myIcon, StartPoint.X, StartPoint.Y); base.OnPaint(e); } Update 3: External Invalidation This variant works well, but... from exterior of IconLineShape class: private void panel1_MouseMove(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { Region r = myLine.Region; myLine.StartPoint = e.Location; panel1.Invalidate(r); } } /// /// Test LineShape /// public class IconLineShape : LineShape { Icon myIcon = SystemIcons.Exclamation; Graphics parentGraphics; protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { parentGraphics.DrawIcon(myIcon, StartPoint.X, StartPoint.Y); base.OnPaint(e); } protected override void OnParentChanged(System.EventArgs e) { // Parent is a ShapeContainer // Parent.Parent is a Panel parentGraphics = Parent.Parent.CreateGraphics(); base.OnParentChanged(e); } } Even this resolves the problem of the test example, I need this control to be done inside the control, because I can't force the external "clients" of this control do not forget to save the old region and invalidate the parent each time changing a location...

How to control the time before Windows 7 wakes from standby and hibernates?

- by Ricket

Ever since I reformatted my laptop, it just hasn't been the same. Before reformatting I noticed that if it was in standby for around 24 hours, it would automatically wake up and go into hibernation. I think that's a pretty cool feature and I didn't mind it. But lately, it's been waiting only a few hours (maybe 3-6; I haven't really timed it or paid enough attention) before waking up from standby and going into hibernation. There have been a few instances where this has been bothersome, and I'd like to change it back to a nice long wait time. Where is this setting? What setting in Windows controls the time before the computer wakes up from standby and goes into hibernation?
