• One samba directory is very slow

  - by Tim Rosser

  We have a RHEL server running as a samba server for our Windows network which has been running fine for ages. All of a sudden this morning one specific folder became really slow and sometimes inaccessible. It's the /home/ directory (containing all of the user specific stuff, like their windows desktops, documents etc). It's not only really slow over the network, but when I try to use ls to view the directory it just hangs. I'm getting loads of messages like the following in /var/log/messages Mar 20 09:53:32 zeus smbd[32378]: [2012/03/20 09:53:32, 0] smbd/service.c:set_current_service(184) Mar 20 09:53:32 zeus smbd[32378]: chdir (/opt/shares/home/tim.rosser) failed

• How can I set the Root Namespace property correctly in a C++/CLI application?

  - by Matthew Bowen

  I have a C++/CLI application in Visual Studio 2008 whose namespace follows the .NET guideline of CompanyName.TechnologyName[.Feature][.Design]. The problem is that there seems to be no way to set a multi-level namespace in the project's Root Namespace property. I have tried both CompanyName.TechnologyName and CompanyName::TechnologyName. It seems that I cannot have a Form control inside a namespace that is not the root namespace as this causes the resources it uses to not be found, thus to me it seems impossible to follow their guideline and be consistent with my C# applications. Is there a way to set this property to use multi-leveled namespaces or am I forced to use a root namespace that is simply one-level? Or is there a solution that I am overlooking? Any help would be appreciated. Thanks

• Is it possible to create a service like Feed My Inbox on my own server?

  - by Mark Bowen

  I was just wondering if it's at all possible to create a service like Feed My Inbox on my own server using PHP? Basically I have a site which has RSS feeds which are dynamic in nature and can search from thousands of posts based on many different criteria. I have the RSS feed working fine and bringing back data dynamically for whatever criteria I want so that bits fine. I am using the ExpressionEngine CMS to handle the site and there will be thousands of users on the site (currently there are around 2,0000) but that number is exponentially growing every single day. What I want to be able to do is allow the users to choose from certain criteria which will then build a dynamic RSS URL which will then be stored in a database table (one row for each user). This bit I will be able to do myself but then I want to be able to send out new RSS feed items via e-mail to each user. This is the part I'm a little stuck on. I'm guessing I would somehow need to run a cron job to hit a page which would check each users RSS feed and then if there are new items to send them to the user via e-mail. That's where I am totally stuck though and I'm just wondering what the best way to go about it would be? That or any software in PHP that already does this sort of thing would be great. I tried out phpList but it has severe problems working with RSS and I only ever got it to work once and now never again and I've read that lots of people have had this same problem so unfortunately it's not just me :-( I know there are services such as Feed My Inbox which I could easily set up so that users click a link and their RSS feed URL is added to go and use that service but I want to keep users from seeing the dynamic nature of the feed or they will easily be able to modify it to get at other items in the feed. I need this so that I can charge for access to the feeds but if people can see the URL of the feed then I will be totally unstuck as they will be able to get at whatever they want very easily. Therefore I'd like to be able to send the items out to them. Would really love to hear if anyone knows if this kind of thing is possible at all and what would be involved?

• c# - can you make a "weak" assembly reference to a strong named assembly

  - by Tim

  hi, for various reasons i would rather not use strong named (signed) assemblies in my project. however, one of the projects is referenced by a sharepoint web part which means it must be signed. is it possible to have this assembly signed but when I reference it from other projects, to do so using a non-strong reference. this would give me the advantages of having a non-signed assembly for the rest of my code but still allow it to be loaded by sharepoint Tim

• Removing table prefixes on ASP.NET MVC DataModel entities

  - by Tim Shults

  My database tables have prefixes on them and when the DataModel generates the EntityObjects they have the prefixes at the beginning of the class name. Is there anyway that I can have those prefixes ignored when the DataModel is updating/creating the classes? I've found the below question, but with no solution. http://stackoverflow.com/questions/1800065/removing-table-prefix-in-linq2sql-setup/2525827#2525827 Thanks in advance, Tim Shults

  I have an SVN repository that I've set up on my VPS, and I know all the basics (update, commit), but I don't know what all the other options mean.

• How do I make multi-page landscape tables in LaTeX

  The title is pretty much the extent of my question. I am trying to insert a large table into a document using the xtabular environment.

Thanks \begin{landscape} \singlespace \begin{xtabular}{|c|c|c|c|c|} \hline some & stuff & ... & \\ \end{xtabular} \end{landscape} Tim

• Rendering GDI components to a buffer or d3d texture

  - by Tim

  Hi, I'm trying to redirect the output of a GDI application to a buffer, preferably a d3d texture but I'll settle for a system memory buffer that I can then copy to a d3d texture. Specifically, I'm trying to get Google Chrome to render into a d3d buffer to be displayed in a d3d application. Are there any foolproof ways to do this or am I opening the mother of all worm-cans? Thanks, Tim.

• Check if webbased CertEnroll will succeed

  - by Tim Mahy

  Hi all, for a project we will be doing webbased certificate enrollment, in Vista / Win7 combination with IE this gives some problems if the user does not import the root certificate first and then changes a lot of default IE settings (Enable ActiveX not marked safe for scripting etc....). I was wondering if any of you ever created a test VB or Javascript to test that all the settings are OK. So it can be used by the user before he starts the enrollment process.... greetings, Tim

• Linq to Sql get SqlCommand when stored procedure execution fails

  - by Tim Mahy

  Hi all, currently I'm assigning a TextWriter to the Log property of my Linq to Sql data context (per request instancing) and write this to my logging when an exception is thrown while executing a stored procedure (is strongly typed mapped in the context, so not executing a custom command) however when using ADO.NET we normally inspect the SqlCommand upon unhandled exception to read out the parameters and log them is it possible to access the SqlCommand that was used for executing a Stored Procedure in L2S so we can reuse that existing logging component? This would be far nicer than the current Log TextWriter solution.... greetings, Tim

• C++: Can virtual inheritance be detected at compile time?

  - by Tim

  I would like to determine at compile time if a pointer to Derived can be cast from a pointer to Base without dynamic_cast<. Is this possible using templates and metaprogramming? This isn't exactly the same problem as determining if Base is a virtual base class of Derived, because Base could be the super class of a virtual base class of Derived. Thanks, Tim

• Web based KVM management for Ubuntu

  - by Tim

  Hey all, We've got a single Ubuntu 9.10 root server on which we want to run multiple KVM virtual machines. To administer these virtual machines I'd like a web based KVM management tool, but I don't know which one to choose from the list of tools mentioned on linux-kvm.org. I've used virsh & virt-manager on my desktop, but would like a web interface for the server. I tested ConVirt on my desktop, but it failed to pickup KVM machines from virsh / virt-manager, and I could not get KVM virtual machine import to work (only Xen). oVirt looks good, but I can't find out if and how I can install it on Ubuntu 9.10.. (And I'd really rather not waste another few days on testing stuff that might not work in the end.) Can anyone recommend any good web based KVM management tools that are easy to install on Ubuntu 9.10? I'm looking for something that will also allow me to run other services like apache and postgresql besides hosting virtual machines, so preferably fairly lightweight & no dedicated OS installs. We don't need any professional clustering / migration or anything, just something that will let us create, start, inspect, administer & stop virtual machines from a web page. Best regards, Tim

• Apache mod-pagespeed installation affects mod-spdy?

  - by tim peterson

  Recently my site (an https connection, running on an Amazon EC2 ubuntu apache2.2) has this issue where I need to load the page several times (3-4) before it will load normally without issue. It will then load normally as long as I keep loading pages regularly (every couple seconds). It will stall again if I don't load pages for a few minutes. It has nothing to do with my application because I don't have this problem with the exact same app codebase on my Apache installation on my laptop. The only things to my knowledge that I've changed is that I recently installed mod_spdy and then a few weeks later I installed mod_pagespeed, https://developers.google.com/speed/pagespeed/mod. However, I have since turned mod_pagespeed off by setting its pagespeed.conf to mod_pagespeed off. Unfortunately, that didn't solve the problem. The line below is how every of last 10 lines of my error.log look: # tail -f /var/log/apache2/error.log ... [32728:32729:ERROR:mod_spdy.cc(162)] request->chunked == 1 in request GET / HTTP/1.1 [Sat Jun 02 04:50:08 2012] [warn] [client 50.136.93.153] [stream 5] [32728:32729:WARNING:http_to_spdy_filter.cc(113)] HttpToSpdyFilter is not the last filter in the chain: chunk any thoughts? thank you, tim

• Page reload needed several times before loading normally

  - by tim peterson

  Sorry my question is so vague I just have no idea where to start in solving it and am quite a novice with servers. Recently my site (an https connection, running on an Amazon EC2 ubuntu apache2.2) has this issue where I need to load the page several times (3-4) before it will load normally without issue. It will then load normally as long as I keep loading pages regularly (every couple seconds). It will stall again if I don't load pages for a few minutes. It has nothing to do with my application because I don't have this problem with the exact same app codebase on my Apache installation on my laptop. The only thing to my knowledge that I changed is that I installed mod_pagespeed https://developers.google.com/speed/pagespeed/mod. However, I have since turned it off by setting my pagespeed.conf to mod_pagespeed off. Unfortunately, that didn't solve the problem. I'm wondering general advice on how to troubleshoot this problem. For instance are there linux commands to check page loading peformance? Also, it looks like I have lots of new error.logs in my /var/log/apache2 directory which i believe weren't there a few months ago. lots of this : error.log RewriteLog.log.24.gz ssl_access.log.40.gz error.log.1 RewriteLog.log.25.gz ssl_access.log.41.gz error.log.10.gz RewriteLog.log.26.gz ssl_access.log.42.gz error.log.11.gz RewriteLog.log.27.gz any thoughts? thank you, tim
