  • Sharing information between nodes in Beowulf Cluster

    - by Alejandro Sazo
    I am setting up a beowulf cluster and I've been reading that it might be necessary to make the home directory of the cluster users shared between them (assuming this users are local to each machine). The other case is leave each user with its own home and the communication is up to the master node. Another idea that came up was to use an LDAP unique user logged on each machine in the cluster, that keeps the idea of the shared home between nodes (but is only one home of one user). Which approach is better for this kind of cluster? Edit: The cluster is running openmpi and it will support cuda and opencl

  • SharePoint 2010 - Can two or more people edit a file at the same time?

    - by Tobias Funke
    I have a SharePoint 2010 site with a document library for storing Excel files. If someone is editing an Excel file (using stand-alone Excel, not Excel services), everyone else will be forced to open the file read-only until the first person is done editing. Is there a way around this? What I want is to allow two or more people to be able to edit the file at the same time. Also, I don't want people to overwrite each other. Instead, I'd like SharePoint to merge their changes. Is this possible in SharePoint 2010?

  • PHP Startup: Unable to load dynamic library '/usr/lib/php5/20100525/apc.so'

    - by user3207586
    I have updated my php from 5.3.3 to 5.4.31. I have a Debian 6 Squeeze.

  • How to start Windows Explorer as domain administrator [closed]

    - by Otiel
    Possible Duplicate: How do you run windows explorer as a different user? Is it possible to start a Windows Explorer with the rights of another domain user? I tried to do the following to start a Windows Explorer on my computer as my domain Administrator, but without success: Right click on C:\Windows\explorer.exe to select Run as different user, Enter the domain administrator credentials: Domain\Administrator ************ The windows explorer session only opens with my current user rights (Domain\me). The reason behind my question is that I want to change some folder rights on a domain shared disk and I need the Domain\Administrator user rights to do it. Usually, I do it by login as Domain\Administrator on the server hosting the shared disk but I would like to be able to do it from my PC, logged as my current login (Domain\me). EDIT As seen in the linked posts, it is not possible anymore on Windows Vista or 7. On Windows XP, the solution is to do: runas /user:domain\username "explorer /separate"

  • Can't get Apache 2.2.21 to compile with OpenSSL support

    - by angstwad
    Alright -- having a bad couple days here compiling Apache 2.2.21 on CentOS 5.7 with the following configure commands: ./configure --enable-ssl=shared --with-ssl=/usr/local/openssl I've compiled from source OpenSSL 1.0.0e from source: ./config --prefix=/usr/local --openssldir=/usr/local/openssl shared zlib-dynamic I attempt to start Apache and it returns: httpd: Syntax error on line 54 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/mod_ssl.so into server: /usr/local/apache2/modules/mod_ssl.so: undefined symbol: SSL_get_servername If I look at how the libraries are linked, this is what I get: [root@web1 modules]# ldd mod_ssl.so libssl.so.6 => /lib64/libssl.so.6 (0x00002aaaaace4000) libcrypto.so.6 => /lib64/libcrypto.so.6 (0x00002aaaaaf30000) libdl.so.2 => /lib64/libdl.so.2 (0x00002aaaab281000) libz.so.1 => /lib64/libz.so.1 (0x00002aaaab486000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00002aaaab69a000) libc.so.6 => /lib64/libc.so.6 (0x00002aaaab8b5000) libgssapi_krb5.so.2 => /usr/lib64/libgssapi_krb5.so.2 (0x00002aaaabc0e000) libkrb5.so.3 => /usr/lib64/libkrb5.so.3 (0x00002aaaabe3c000) libcom_err.so.2 => /lib64/libcom_err.so.2 (0x00002aaaac0d1000) libk5crypto.so.3 => /usr/lib64/libk5crypto.so.3 (0x00002aaaac2d4000) /lib64/ld-linux-x86-64.so.2 (0x0000555555554000) libkrb5support.so.0 => /usr/lib64/libkrb5support.so.0 (0x00002aaaac4f9000) libkeyutils.so.1 => /lib64/libkeyutils.so.1 (0x00002aaaac702000) libresolv.so.2 => /lib64/libresolv.so.2 (0x00002aaaac904000) libselinux.so.1 => /lib64/libselinux.so.1 (0x00002aaaacb19000) libsepol.so.1 => /lib64/libsepol.so.1 (0x00002aaaacd32000) Basically, I've tired compiling from source OpenSSL (both 0.9.8r and 1e), having yum reinstall from the repos, done a make clean and remade both OpenSSL and Apache numerous times -- but I can't get it to compile into the apache base or dynamically as a shared object file. What am I doing wrong here? Update 1: After doing a make clean and make distclean, I've reconfigured with the same parameters as above without any effect. The config.log is at Pastebin. Update 2: Modifying the LD_LIBRARY_PATH had no effect on the lib-deps of mod_ssl.so. UPDATE 3: I've compiled and recompiled many times, and verified with ldconfig that the OpenSSL libs dir is in my path, and included in ld.so.conf. Still cannot get httpd/mod_ssl to load the library at runtime.

  • Databinding int32 to MaskedEditExtender enabled TextBox

    - by Zach Skinner
    I have a master/detail scheme for editing an asp:GridView using an asp:DetailsView. One of my fields is for a phone number of type int64 (always 10 digits). I would like this field to always be displayed as (###)###-####. My issue is the first digit in the phone number is always truncated for my edit item field which I used a MaskedEditExtender to achieve the formatting. Here is my EditItemTemplate for the details view: <cc1:MaskedEditExtender TargetControlID="edtPROJ_Leader_Phone" Mask="(999)999-9999" runat="server" ClearMaskOnLostFocus="false" ClipboardEnabled="true" MaskType="Number" /> <asp:TextBox ID="edtPROJ_Leader_Phone" runat="server" Text='<%# Bind("PROJ_Leader_Phone") %>' ></asp:TextBox> When my details view is displayed for editing, the text box displays(_23)456-7890 for the integer 1234567890. Also worth noting that if the property MaskType="Number" is removed, the textbox shows: (234)567-890_. I would of course have the textbox show (123)-546-67890 after binding.

  • Plesk 10 Postfix with multiple IP adresses and SSL certificates

    - by JulianB
    We are currently running a root server with Debian 6 and Plesk 10.4.4. We have some virtual hosts using one IP adress (shared) - e.g. example1.com - and another virtual host using a dedicated IP address (example2.com). Is there a way to configure postfix to do the following Always use the IP address of the virtual host to which the e-mail account belongs (so that an e-mail from [email protected] will originate from the shared IP-Address and an e-mail from [email protected] will originate from the dedicated IP? Use different certificates for TLS for example1.com and example2.com? If the latter is not possible: Could any problems arrive when using example1.com as certificate for example2.com users? Of course, example2.com users would have to configure their clients to use example1.com as the SMTP server name to avoid annoying security warnings. But if we still would be able to get the effect of the first point that would still be acceptable.

  • In Ruby, how to I read memory values from an external process?

    - by grg-n-sox
    So all I simply want to do is make a Ruby program that reads some values from known memory address in another process's virtual memory. Through my research and basic knowledge of hex editing a running process's x86 assembly in memory, I have found the base address and offsets for the values in memory I want. I do not want to change them; I just want to read them. I asked a developer of a memory editor how to approach this abstract of language and assuming a Windows platform. He told me the Win32API calls for OpenProcess, CreateProcess, ReadProcessMemory, and WriteProcessMemory were the way to go using either C or C++. I think that the way to go would be just using the Win32API class and mapping two instances of it; One for either OpenProcess or CreateProcess, depending on if the user already has th process running or not, and another instance will be mapped to ReadProcessMemory. I probably still need to find the function for getting the list of running processes so I know which running process is the one I want if it is running already. This would take some work to put all together, but I am figuring it wouldn't be too bad to code up. It is just a new area of programming for me since I have never worked this low level from a high level language (well, higher level than C anyways). I am just wondering of the ways to approach this. I could just use a bunch or Win32API calls, but that means having to deal with a bunch of string and array pack and unpacking that is system dependant I want to eventually make this work cross-platform since the process I am reading from is produced from an executable that has multiple platform builds, (I know the memory address changes from system to system. The idea is to have a flat file that contains all memory mappings so the Ruby program can just match the current platform environment to the matching memory mapping.) but from the looks of things I'll just have to make a class that wraps whatever is the current platform's system shared library memory related function calls. For all I know, there could already exist a Ruby gem that takes care of all of this for me that I am just not finding. I could also possibly try editing the executables for each build to make it so whenever the memory values I want to read from are written to by the process, it also writes a copy of the new value to a space in shared memory that I somehow have Ruby make an instance of a class that is a pointer under the hood to that shared memory address and somehow signal to the Ruby program that the value was updated and should be reloaded. Basically a interrupt based system would be nice, but since the purpose of reading these values is just to send to a scoreboard broadcasted from a central server, I could just stick to a polling based system that sends updates at fixed time intervals. I also could just abandon Ruby altogether and go for C or C++ but I do not know those nearly as well. I actually know more x86 than C++ and I only know C as far as system independent ANSI C and have never dealt with shared system libraries before. So is there a gem or lesser known module available that has already done this? If not, then any additional information as to how to accomplish this would be nice. I guess, long story short, how do I do all this? Thanks in advance, Grg PS: Also a confirmation that those Win32API calls should be aimed at the kernel32.dll library would be nice.

  • Multiple file types in vim

    - by Chad
    When I am working on a PHP file for example the default filetype is php. This makes sense, however when that PHP file has HTML as well the filetype is still only php. For some plugins that means that I get the PHP functionality for that plugin, but miss out on the HTML functionality. A more specific situation where this happens is with my snippet plugin. I get php snippets and not html snippets when I am editing a php file. Possible solutions to this (which I obviously don't like, hence my posting this question) are: add a map to toggle between different filetypes when I am editing different sections of the file. update my php snippets file to include the html snippets as well (while this would work for the example above, it doesn't solve the fundamental problem). So, Is there a way to edit a file using multiple filetypes at the same time in vim?

  • image rendering issue

    - by burkejam71
    I am running Apache/2.2.3 (CentOS). For some reason certain images, jpg, gif, or png will show up as byte code when accessed directly on the server. Firefox 3 and Safari both think the content type is text/html. IE I believe has something built in to recognize it is an image and ignore the content type and renders the image correctly regardless. I can't seem to find anyone else with this issue. An example of this can be found at http://www.thedacs.com/admin/gp/userfiles/image/gp28%5Fimg%5F01.jpg but the image below on same server the image is rendered correctly (use same path from above) Fig3mod.jpg The first image works fine in Photoshop CS, Illistrator, GIMP, Paint.net,and any other image editing software. I have tried everything when editing the images from trying multiple file formats to print screens and cropping to create a new image to lose old image meta data. Can anybody help?

  • What is a good dumbed-down, safe template system for PHP?

    - by Wilhelm
    (Summary: My users need to be able to edit the structure of their dynamically generated web pages without being able to do any damage.) Greetings, ladies and gentlemen. I am currently working on a service where customers from a specific demographic can create a specific type of web site and fill it with their own content. The system is written in PHP. Many of the users of this system wish to edit how their particular web site looks, or, more commonly, have a designer do it for them. Editing the CSS is fine and dandy, but sometimes that's not enough. Sometimes they want to shuffle the entire page structure around by editing the raw HTML of the dynamically created web pages. The templating system used by WordPress is, as far as I can see, perfect for my use. Except for one thing which is critically important. In addition to being able to edit how comments are displayed or where the menu goes, someone editing a template can have that template execute arbitrary PHP code. As the same codebase runs all these different sites, with all content in the same databse, allowing my users to run arbitrary code is clearly out of the question. So what I need, is a dumbed-down, idiot-proof templating system where my users can edit most of the page structure on their own, pulling in the dynamic sections wherever, without being able to even echo 1+1;. Observe the following psuedocode: <!DOCTYPE html> <title><!-- $title --></title> <!-- header() --> <!-- menu() --> <div>Some random custom crap added by the user.</div> <!-- page_content() --> That's the degree of power I'd like to grant my users. They don't need to do their own loops or calculations or anything. Just include my variables and functions and leave the rest to me. I'm sure I'm not the only person on the planet that needs something like this. Do you know of any ready-made templating systems I could use? Thanks in advance for your reply.

  • Is there any HTML wysiwyg editor?

    - by martin
    I wonder whether there is any good WYSIWYG editor when it comes to editing complex HTML pages generated from ASP.NET, PHP, GWT or anything else. I've tried a lot of WYSIWYG tools, but after a certain point I always end up with manually editing the HTML source code or CSS to fix different issues. The editors I've tried are never compatible with the ASP.NET/PHP/etc code I'm writing. Edit: I have used Visual Studio for a few years to do ASP.NET development. After a while, it always comes to the point where I can't even open the pages and user controls because they rely on so many things which aren't available in debug time.

  • Sending SPAM free mail through my website

    - by Sara
    Hi, I've been battling with this issue for couple of months. I need to send bulk mail (not spam) through my social network to users in situations like newsletters, site invitations (when user imports their address book contacts) I'm using shared hosting and it limits 500 mails per hour. Even though i manage to send mails most of them end up in user's spam box. After researching these are the solutions that i finally came up with. 1) Use Google Apps SMTP (http://www.google.com/apps/intl/en/business/features.html) 2) Move into VPS 3) Use shared hosting with throttle enabled Please advise me on what to choose. Will using Google Apps prevent mail being sent as spam? I can't use other 3rd party SMTP like iContact or Aweber as "invitation sending script" will send emails to thousands of contacts, depending on user's addressbook. Thanks in advance

  • Trim "Minify" inline css at runtime, expand it at edit time.

    - by Scott B
    My custom WP theme has a text block in the theme options panel that allows the user to create and maintain a custom css block that is applied to the site template at runtime. I would like to trim or "minify" this content before its stored in the database, but retain all the whitespace when its presented back to the user for editing. Would this be possible? For example, if the user has entered the following as their custom css code... .red {color:red;} .green {color:green;} .blue {color:blue;} Then I would like to store it in the database as: .red{color:red;}.green{color:green;}.blue{color:blue;} But still display it as it was input (ie, retain all the white space and line breaks) when the user is editing the content via my theme options panel.

  • Capture Silverlight 4 event when panel clicked

    - by Eric J.
    I have a small Silverlight 4 app that essentially consists of a grid containing a label and a combo box. When I click the label, I replace it with a second text box so that I can edit the label (much the way you can edit the name of a Silverlight control in VS2010). I have a LostFocus event handler on the text box that will end editing when the control loses focus (restoring the updated label). Trouble is, users tend to click on the panel when they are done editing rather than on another control (or hitting Enter, which is also supported). I tried adding a left mouse down event handler to the panel. However, that only fires when the text box does not have the focus (I guess the text box captured the mouse?) Is there an approach to recognize that a non-input control was clicked that would enable me to terminate edit mode?

  • How to prevent Mac OS X creating .DS_Store files on non Mac (HFS) Volumes?

    - by sudo petruza
    Is there a way to prevent Mac OS X creating .DS_Store and other hidden meta-files on foreign volumes like NTFS and FAT? I share an NTFS partition with data like Thunderird & Firefox's profiles and apache's DocumentRoot, between Mac OS X and Windows, which is very handy. I don't mind if Mac OS X is not capable of indexing or otherwise doing the neat things those metafiles are for. Note: It's not shared over a network, both operating systems and the shared partition coexist on the same disk, on the same machine.

  • Using Office 2010 web apps with ASP.NET

    - by Martin de Ruiter
    Would it be possible to use the Office 2010 web apps with an ASP.NET application? For example: - For each user of my ASP.NET application there is a folder with Word documents on my server - The ASP.NET application displays the available documents in a grid to the user - When clicking on one of the documents in the grid, the Word document is loaded in an IFrame which contains the Office 2010 web apps Word interface and editing of the document can take place - After editing, the document can be saved to the server, and the ASP.NET grid displays an updated status Would such a scenario be possible? And what do you need, e.g. Sharepoint, Office 2010 licenses?

  • PHP Tag Cloud System

    - by deniz
    Hi, I am implementing a tag cloud system based on this recommendation. (However, I am not using foreign keys) I am allowing up to 25 tags. My question is, how can I handle editing on the items? I have this item adding/editing page: Title: Description: Tags: (example data) computer, book, web, design If someone edits an item details, do I need to delete all the tags from Item2Tag table first, then add the new elements? For instance, someone changed the data to this: Tags: (example data) computer, book, web, newspaper Do I need to delete all the tags from Item2Tag table, and then add these elements? It seems inefficient, but I could find a more efficient way. The other problem is with this way is, if someone edits description but does not change the tags box, I still need to delete all the elements from Item2Tag table and add the same element. I am not an experienced PHP coder, so could you suggest a better way to handle this? (pure PHP/MySQL solution is preferable) Thanks in advance,

  • Intermittent Disconnection of Client Computers from Domain Server

    - by dilip nagle
    The Background: I have Windows 2008 server Enterprise Version with 25 user cal licences. It has a domain and all users and a network shared HP printer in it. The Server has two network cards and both these cards as well as all client machines are on IP addressing scheme of 192.168.1.* with subnetmask 255.255.255.0. Of the two network cards viz. 192.168.1.231 and 192.168.1.233, only 192.168.1.231 is registered with DNS. In 192.168.1.233(i.e. 2nd network card) has default getway as 192.168.1.231 and dns address as 192.168.1.231. The Server has three hard disks with capacities as 500gb, 500gb and 1TB and are partitioned as (C,D,E), (F,G) and (K) with partition K having all user data into various Shared Folders. Each of these folders(On Partition K), are mapped onto each user's computer as per the right of access given to them. The Problem: The Server was installed about 6 months ago and till date not even once, the Server has Hung or has given any problem. All the Clients computers are able to run the web based software from their computers via ip address, e.g. http://192.168.1.231/webERP/default.aspx. However, occassionally, when any client computer tries to browse network mappings, it hangs. Again, there is no fixed pattern. This may happen after running smoothly for say 3 days. On each Client's machine, the network settings are as follows: IP Address: 192.168.1.* where * is 1,2,3 .... Sunnetmask: 255.255.255.0 defauly getway: 192.168.1.231 Which is a server card and DNS address. preferred DNS Server: 192.168.1.231 In Advanced Tab under Wins: LMHostLookup is Unticked and default is radio buttoned. Ideally, I would have loved to have Disabled NETBIOS over TCP/IP but some network printers do not get accessed if this option is enabled(ie. Radio Buttoned). Bacause Disabling Netbios will drastically reduce traffic of NETBIOS broadcasting to all the computers on the net to do naming resolution. On Server, I have WINs Running which I have Scavanged Records, verified Database Integrity etc, removed Tombstoned Records etc. The Critical Errors shown only once a day when the server is statred are 4224(WINS) and 12923 - Server Licencing failed to Update DNS Record. I fail to understand as why do client machines HANG when they try to browse mapped network shared folders on K Drive. Kindly Advice

  • Can Time Capsule backup its own network share or can Time Machine be setup to do so?

    - by Sam Brightman
    Apple's Time Capsule can act as both a backup drive and a network shared drive at the same time. Can it backup its own data to incremental backups? I can't find this information anywhere. I've not used Time Machine so I don't know if it can be configured to backup shared drives (independently of whether Time Capsule has the option). I would like this to be a feasible way of freeing up some storage on an older MacBook Air by keeping large media such as photos archived on the drive like you would a USB external drive. But having the only copy accessible throughout the house and not backed up would make me nervous. I like the idea of having a good router, network storage and backup in one box, although obviously it's safer to backup the Capsule itself to USB occasionally too. Other solutions to this are of course welcome if this is not possible.

  • Non-Registry Fix for Secondary Mailboxes Sent Items

    - by Jai Kang
    There is a known issue with Outlook and Exchange where "secondary" mailboxes which are mounted in the same profile, e.g. "John Doe" + CorpMailbox1, CorpMailbox2, CorpMailbox3 will place "sent items" from the secondary mailboxes (e.g. CorpMailbox1) in the user's (e.g. "John Doe") Sent Items folder. There is a registry value (something like DelegateSentItems) to semi-fix this, but I'm looking for an Exchange-side solution. It seems like, at some point, an admin made CC rules to fix this, and for the mailboxes where I see a BCC rule: any item sent to [address] BCC to [address]. The behavior "fixes" the issue, but when I duplicate this work-around for new shared mailboxes, the email ends up in the Inbox and not the Sent Items for the shared mailbox. I don't believe there is any outlook/client-side shenanigans going on, as the intended behavior for the older mailboxes works for new PCs/Users (new imagse) without any Outlook Mailbox Rules.
