• HPC Cluster planning workflow?

  - by Veronica

  After three days of intensive Google searching, I have not found any high-level workflow of how to build a low profile - cheap - computing cluster (we are not interested in HA yet). This is just a front-end plus a node for now. We want to start small with rockscluster, provide a web-based server for offering services, and then add nodes as our budget increases. We're small company, so we haven't enough human resources to implement it smoothly. Here are some facts about our environment: Our hardware is not constant (we will add nodes). Our workload will vary (in the order from 200Mb - 1Tb) Our software will change (scientific applications for data mining) Do you know any visual workflow, worksheet, chart, describing the general necessary steps to begin our cluster planning?

• Outlook new message size nearly 1mb

  - by Yossi Dahan

  I've been using Outlook 2010 for several weeks with no issues. Suddently, a few days ago, the size of my outgoing messages got huge. Looking at thsi it appeas that a huge CSS style is beign created with around 14,000 definition for list items, making the message almost 1mb before I even typed in one word. Emails before that point were very small. Needless to say I can't remember changing anything, nor can anyone around here provide any possible explanation... Any ideas?

• creating decision tree based troubleshooting documentation?

  - by Joseph

  We troubleshoot a lot of server and network issues and follow a loose set of steps on what to do in different cases. With more and more people and responsibility, the need for standardization is needed so we don't miss something. I know I could accomplish what I want using flowcharts, but I'd like to do something similar to a "Choose Your Own Adventure" style. I think this is pretty much the same as what support call centers seem to do. Are there any tools to make creating such documentation easier? I'm looking for a web based approach if possible.

• Keepalived takes several minutes to recover in a particular situation

  - by NathanE

  I've setup Keepalived for a master-slave style virtual IP and it seems to work well. Both are hosted in almost identical VMs. If I "pause" the VM that is running the Master. The Slave will take over, as expected, almost instantly. However if I then "unpause" the VM that runs the Master. The virtual IP will stop responding the pings. And it takes a good 4 or 5 minutes for it to start pinging again. It seems to be getting desynchronised due to the nature of the way I'm testing it (by pausing/unpausing the VMs). I admit that pausing and unpausing VMs is a slightly dodgy way to test this. But it has raised a concern for me that there could be other scenarios that cause the same undesirable behaviour. Is this expected / by design? Is there anything I can do to the config to improve it? Thanks.

• remote desktop network failed connection

  - by tbischel

  I was trying to create a remote desktop connection from Windows XP to my Windows Vista Ultimate Addition machine at home. This normally works fine. Today after my connection was dropped, I tried to reconnect to my machine. It brings me to the normal startup screen, but when I tried to log in, it gave me the message "This network connection doesn't exist". This doesn't make much sense, as I have reached a Windows style login screen already. My connection returned later that day, but I'm curious as to what happened. Anyone see this before?

• How to make numbered chapter titles and paragraph headers in iWork Pages 09?

  - by dyve

  For most of my document writing I use iWork Pages (from iWork '09), and it's usually fine for me. I don't miss Microsoft Word, except for one simple feature: the ability to number chapter titles and paragraph headers for easy reference in the contents of the document and for cross references. Somehow, I cannot find this feature in Pages '09. It is possible to number headers by setting the style to numbered, but it doesn't mitigate well into the generated dynamic contents, and paragraphs don't follow the numbering of higher level elements it seems. Does anyone know how to make this work?

• How to fix poor rendering in Windows Movie Maker?

  - by Cyberherbalist

  I am using CamStudio to make some instructional videos about Visual Studio for our development team, and one of the videos needed some editing to remove audio and video mistakes and to add in a better ending. CamStudio outputs to .avi files, and they look pretty good, with the program source code being quite readable. However, after making the edits using WMM, it has rendered the results to a noticeable loss in quality. It has gone from from fairly sharp in focus and adequately readable to recognizable but somewhat blurred. It has also inflated the size of the new .avi file to three times its original size (before cropping half of the vido out!). And the .wmv I attempted to render was was certainly smaller but simply horrible-looking. The left image here is the original video, and the right image is WMM's rendering in .avi format: I have to be doing something wrong, but I know nothing about how to use WMM (my first use of it). I am using default settings to the best of my knowledge. Any suggestions welcomed!

• Indexing text file content with command line query

  - by Drew Carlton

  I take daily notes in a plaintext file labeled with date in the YYYYMMDD format. These files are no more than 100 lines long, and are written in a blog style format. I'd like to be able search these files as if they were blog posts indexed by google, with some phrase query returning the most relevant/recent date filenames, with a snippet containing the relevant part. Ideally it would be something like this: #searchindex "laptop no sound" returns: 20100909.txt: ... laptop sound isn't working... 20100101.txt ... sound is too loud... debating what laptop to buy... and so on and so forth. I'm working on a linux platform (Debian with GNOME). I've looked at beagle and tracker, but they just seem complete overkill for what I want.

• 32bit Application Memory Usage on 64bit Windows 7

  - by Brian

  I have an early 2012 Macbook Pro with and Intel I7 processor and 16 gigs RAM running Windows 7 Professional 64bit via Bootcamp. I work in Geographical Information Systems as a programmer so most of the applications I am running are 32bit Applications, but tend to use a lot of resources (i.e. ArcGIS, SQL Server Express, Visual Studio, etc.). I have been noticing that when I have multiple instances of either the same 32bit application or different 32bit applications and they are all working on hefty processing tasks, I am still only topping out at about 30% memory use. I understand 32bit applications are limited to less than 4gb RAM, but I assumed that one instance could use its own 4gb while another instance could use another 4gb to take full advantage of all the memory I have installed. Can anyone explain how this works and how I can get my applications to take advantage of all my memory via running multiple instances?

• Website deployment - managing user-uploaded content?

  - by Legion

  I'm a programmer by trade, "server administrator" by company necessity. We're looking at dumping the old painful "update site by FTP upload" style of deployment. Having the webserver check out the latest code base from version control into a folder and having a "current" symlink point to the latest checkout (allowing for easily stepping back to an older version by changing the symlink) seems to be the way we want to go. But I have a question: what's a good practice for dealing with user-uploaded content? This stuff isn't in version control. I have a couple of ideas for dealing with this, but what is the smart, accepted practice?

• How to handle user accounts for many sites running on same server

  - by Simon Courtenage

  Background to this question: I want to host multiple e-commerce sites on the same server, each with their own separate customer login application. Each site's login application needs to be secured by SSL. I'm unsure how best to handle this. For example, do I need to acquire a separate SSL certificate for each site (in which case, how do I do this dynamically, as the sites are created), or do I handle this using ONE login gateway-style application, which handles it on behalf of all the sites via a kind of transparent redirect? I'd be grateful for any pointers or advice. Thanks.

• Un-table a cell range in Excel 2007

  - by Joe

  In Excel 2007, if you highlight a block of cells and then "Format as Table", it doesn't just apply colors and formatting, it somehow marks those cells as being a table. Now I want to get rid of the table, but keep all the cells (i.e. keep the data). So I tried clearing the table style and formatting, but Excel still recognizes those cells as being a table. I can tell because: When I select a cell that was in the table, Excel still displays the "Table Tools / Design" tab I cannot merge cells that were in the table <- this is what's annoying me So, how do I un-table those cells? I want to keep all the cell data and formatting, but have Excel not recognize them as a table.

• Diagnosing extremely slow network operations.

  - by Chris Becke

  The network: * A windows 7 PC with 2 NICs - one connected to an old style ethernet hub - the other to the internet - with internet sharing enabled * An Apple iMac connected to the hub, successfully utilizing the ICS to access the internet. My problem: Using the Mac, copying from the internet is fast. However, if I connect to a SMB: share on the Windows 7 PC and try and copy anything a few kb the copy operation is appallingly slow with my network card using the Windows 7 control panel showing ~.1% utilization. The NICs are 100Mbs and show a 10x larger throughput (now ~1%) if I download large files over the internet using the Mac. WTF?

• What is the name of this screw? (from HP ProLiant quick-deploy rail kits)

  - by kockiren

  I need the name of the screw for the HP quick deploy rail kit. The screw clicks into the square holes of the rack. It is a Gen4 Rail kit but the screw is like the Gen8 Rail kit ones. I called HP support, but they couldn't really help me. Unfortunately the rack manual does not name this screw either. After googling a while, I found the compatible "Thumb Style Rack Screws". It would do the job but isn't exactly what I am looking for. So, what is the name of the pictured screw.

• SQL Server Management Studio - Error connecting to remote DB

  - by Julien Poulin

  All right, here is the deal: I'm connecting to a Windows 2003 Server using VPN. On this server, there is a remote SQL Server 2005 Express engine. I can connect to the database using Visual Studio 2008. What I can't do though, is connect to this same database with SQL Server 2005 Management Studio (Standard). I have checked the connection info a hundred times and still nothing. One thought: do VS ans SSMS use the same sql provider? Note: I'm running Windows 7 RC. I had absolutely no problem using the same config under Vista. This is the error I get when trying to connect with SSMS:

• Is it possible to define a virtual directory in IIS and make the files relative to the physical dir

  - by Mikey John

  Is it possible to define a virtual directory in IIS and somehow make the files in that directory relative to the physical directory and not to the virtual directory ? For instance on my server I have the following folders: D:\WebSite\Css\myTheme.css, D:\WebSite\Images\image1.jpg I created a virtual directory on IIS resources.mysite: Inside my website I reference the sheet like this resources.mysite/myTheme.css But inside myTheme.css I reference pictures from ../Images/images1.jpg. So the problem is that image1.jpg is not found because it is relative to the physical folder and not the virtual folder on IIS. Can I solve this problem without modifying the style sheet ?

• How to generate an ASCII representation of a Unix file hierarchy?

  - by Jenn D.

  Hi, all. I'm looking for a quick and dirty way to generate some diagrams of some directories that have almost, but not exactly, the same hierarchy, so I can show them around at a meeting and we can decide which flavor we like best. I'm not interested in the "leaf" nodes, just the directories. The catch: I don't want to mess with X. This is a server system I deal with entirely through SSH. So I'm looking for something that will do ASCII layout, maybe with simple pipes-and-hyphens for lines or something. Does anyone know of such a utility? I'm sure I could write something myself, but it's such a fiddly little sort of project, with handling spacing and layout and such; I'd really like to discover that someone's done it for me. Alas, Google doesn't seem to know of such a thing...or if it does, it's hidden beneath heaps of excellent visual explications of the standard general Unix file hierarchy. Thanks!

• Which VMs are easier to install/configure and more performant?

  - by André Alçada Padez

  well, i hope this doesn't get categorized as a boating question, but it really is related to programming. I have windows XP, and i am going to have to have a VM running: Windows 7 Visual Studio 2008 Sql Server 2008 IIS 7 (8 in a little while) Wamp Photoshop CS5 etc... so i was wondering what should i use to be easier to install and configure, and best performance: Virtual Box or Microsoft's Virtual Machine? Thank you Well i tried Virtual Box, it's always crashing for some reason. I think i'm going to try Virtual PC, just to stick to an all Microsoft Solution.

• Why not install Msvcr71.dll into system32?

  - by hillu

  While looking for an authoritative source for the missing Msvcr71.dll that is needed by a few old applications, I stumbled across the MSDN article Redistribution of the shared C runtime component in Visual C++. The advice given to developers is to drop the DLL into the application's directory instead of system32 since DLLs in this directory are considered before the system paths. What can/will go wrong if I (as an administrator, not a developer) decide to take the lazy path and install Msvcr71.dll (and Msvcp71.dll while I'm at it) into the system32 directory (of 32 bit Windows XP or Windows 7 systems) instead of putting a copy in each application's directory? Is there another good solution to provide the applications with the needed DLLs that doesn't involve copying stuff to the application directories?

• 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.

• How to combine wildcards and spaces (quotes) in an Windows command?

  - by Jan Fabry

  I want to remove directories of the following format: C:\Program Files\FogBugz\Plugins\cache\[email protected]_NN NN is a number, so I want to use a wildcard (this is part of a post-build step in Visual Studio). The problem is that I need to combine quotes around the path name (for the space in Program Files) with a wildcard to match the end of the path. I already found out that rd is the remove command that accepts wildcards, but where do I put the quotes? I have tried no ending quote (works for dir), ...example.com*", ...example.com"*, ...example.com_??", ...cache\"[email protected]*, ...cache"\[email protected]*, but none of them work. (How many commands to remove a file/directory are there in Windows anyway? And why do they all differ in capabilities?)

• Is there any way to get tree organisation for Windows 7 file explorer favorites?

  - by fostandy

  In XP there was a MenuBar called Favorites which seemed to be based on Internet Explorer Favorites. It was fantastic because it allowed for very fast tree style navigation (if set up correctly you could navigate it using first letter keystrokes, so to access a shortcut named "videos" in a folder named "files" was as quick as Alt-A f v) This was removed in Vista (and imo generally regressed the file explorer). This was fine because I never used it, but I'm resigned to eventually embracing the inevitability that is Windows 7. Dealing with a single non-nested list of favourites is pretty painful to me as I have quite a lot of them. Is there a way to make a tree like favorites structure in Windows 7? My fingers are crossed.
