• PERC H710 mini raid controller advanced settings (BIOS)

  - by gregg

  I upgraded from a PERC h310 to an H710 controller on my Dell R620 but didnt get any increase in performance. This is a ESXi host with a 5 disk RAID 5. I noticed when going to the RAID BIOS that the advanced settings section was not activated/checked off. In that section is the strip element size: 64kb (default) read policy: no read ahead and the write policy: write-through. Will checking that section do any harm to the existing raid array or will it simply enable those policies and hopefully boost performance? Or, lastly, is it already using those policies and the checkmark is simply to activate them for changes

• amazon dynamoDB or MySQL for storing large arrays inside each row

  - by Logan Besecker

  I am trying to decide which database I should use for an application I'm making. I was leaning toward dynamoDB because of its scalability, but then I read in the documentation which said: there is a limit of 64 KB on the item size although it looks like MySQL has a similar restriction documented here This application will be storing a lot of data in two arrays, which could contain upwards of 10,000-100,000 strings in each. I estimate that these strings will each be somewhere around 20 characters long, so each element of the array will be around 40bytes and each array could be around 4MB. Given this predicament, what database on amazon AWS would you use; or how would you get around the limit of size per row? Thanks in advance, Logan Besecker

• how to determine which of the installed chrome extensions are showing text-enhanced ads or are injecting new CSS class names?

  - by syedrakib

  I have three google users [personal, work, work] in my chrome on Mac OS X. The chrome for my personal account [not the other two chromes] has text-enhanced ads in every site i go to. It double-underlines some keywords on every page. On mouse hover I get an ad overlay from http[colon][slash][slash]intext.nav-links.com[slash] Upon right-clicking one of the text-enhanced keywords and going to 'inspect element', i see that the text has been wrapped around with a CSS classname called adtext. It even shows the .adtext CSS descriptions on the right. How do i determine from WHICH particular extension is this CSS classname being injected into my pages?

  - by Michiel Overeem

  I'm running Windows7 Enterprise, x64 version.

• Firefox: box mode?

  - by Peter Mortensen

  What is the "box mode" (for a lack of a better word) in Firefox? How can I exit it again? If I hold down the Ctrl key and left click while the cursor is over some element on a page it becomes boxed: Firefox seems to go into some special mode. What is this mode for? How can I go back to normal mode? Installed add-ons in Firefox: BetterPrivacy 1.29, NoScript 1.9.0.6 and SQLite Manager 0.4.7. (Microsoft .NET Framework Assistent 1.0 is disabled.) Platform: Firefox 3.0.6, Windows XP 64 bit SP2, 8 GB RAM.

• Arch Linux Terminal (via ssh) + Dropbox but sync only 1 single selected folder

  - by Norfeldt

  Sorry for the weird title... I'm (still) quite new to linux and are doing shh commands to an Arch Linux device that has not screen output options. So everything has to be done in the terminal (not my super element). I use the linux device to play around with python (which is quite fun). Now I would like sync my script folder with dropbox. Since I don't have enought space to sync all my dropbox files to the device, I would like to know how I can set it up in a way that it only syncs with the folder I choose. At the time being I have not installed dropbox because I'm afraid that it will immediately begin to sync all my dropbox folders onto my linux device. BONUS INFO: I already have created a folder in my dropbox that I that contains some py scripts I would like to have synced with my linux device.

• Eclipse Helios on OS X Snow Leopard crashes frequently when editing certain PHP files

  - by William

  I use Eclipse Helios (Eclipse Platform: 3.6.0.I20100608-0911, Eclipse IDE for PHP Developers: 1.3.0.20100617-0520) all the time on OS X (Snow Leopard), and it seems I only run into trouble whenever I'm editing a PHP file that's part of the WordPress blogging framework. When I move my cursor to a variable or function name, that often triggers the beach ball of death. I suspect Eclipse is trying to look up that variable/function and for some reason that causes an endless loop. Sometimes it's not just variables or functions. Just today I was trying to replace all occurrences of a quoted string. Every time I clicked "Replace All", the program would freeze immediately after the string was replaced and the text cursor was moved to the replaced position. I think the moving of the text cursor is important, because I got the same result when I searched for the string (thus moving the cursor), but NOT when I searched for a nonexistent string. I tried disabling everything in my preferences related to marked occurrences, hovering, code assistance, etc. Nothing helps. I use Eclipse for all my projects, and I find that it's only WordPress projects where this happens. Here's my eclipse.ini file: -startup ../../../plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library ../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx_1.1.0.v20100503 -product org.eclipse.epp.package.php.product --launcher.defaultAction openFile -showsplash org.eclipse.platform --launcher.XXMaxPermSize 512m --launcher.defaultAction openFile -vmargs -Dosgi.requiredJavaVersion=1.5 -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -XX:PermSize=128m -XX:MaxPermSize=128m -XX:MaxGCPauseMillis=10 -XX:MaxHeapFreeRatio=70 -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing -XX:CompileThreshold=5 -Xms128m -Xmx512m -Xss2m -Xdock:icon=../Resources/Eclipse.icns -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -framework ../../../plugins/org.eclipse.osgi.services_3.2.100.v20100503.jar I have 4GB of RAM, so I don't know if the problem is I'm underutilizing my resources.

This value will be overwritten using the values from the preferences I did some experimenting with the particular script that's giving me trouble. It's a hybrid of HTML and PHP, so Eclipse has to do both HTML and PHP validation. I wondered if the HTML validation had something to do with it, so I created a new file, copied the contents over, and messed with the doctype element. I found that if I replaced the well-formed XHTML 1.0 Strict doctype element with a generic doctype (as such: <!DOCTYPE html>), then I did not crash the program just by moving the cursor around. I set all HTML validation rules to "Ignore", but it still didn't solve my problems. For now, I'm just going to echo the doctype using PHP instead of entering it literally. That seems to prevent crashes. I notice that when I move the cursor around the document, Eclipse displays the "xpath" to my current location at the bottom of the screen. Sometimes there's a delay while it figures out my current path. Perhaps when it's validating against the Strict doctype, it has problems quickly calculating the xpath as I move the cursor around? Maybe it has a stack overflow that causes it to crash.

• Equivalent of LaTeX "eqnarray" in Microsoft Word 2007 equation editor?

  - by Niten

  In LaTeX one can use the eqnarray environment to display a set of equations aligned horizontally on their equality signs or other element, e.g.: \begin{eqnarray*} x &=& 5! \\ &=& 5 \cdot 4 \cdot 3 \cdot 2 \cdot 1 \end{eqnarray*} This will render as follows (notice the alignment of the equality signs): http://imgur.com/TxH0Y.png (Sorry, I don't have any reputation here yet so I'm not allowed to inline the image.) Is there a good way to achieve the same effect in Microsoft Word 2007's built in equation editor?

• "sed" regex help: Replacing characters

  - by powerbar

  I want to change characters in a XML file by using sed. The input looks like this: <!-- Input --> <root> <tree foo="abcd" bar="abccdcd" /> <dontTouch foo="asd" bar="abc" /> </root> Now I want to change all c to X in the bar tag of the tree element. <!-- Output --> <root> <tree foo="abcd" bar="abXXdXd" /> <dontTouch foo="asd" bar="abc" /> </root> How is the correct sed command? Please consider, there can be more than one occurence of c (next to each other or not) in one tag... I tried this myself, but it won't change multiple c, and it does append a X :( sed -i 's/\(<tree.*bar=\".*\)c\(.*\"\/>\)/\1X\2/g' Input.xml

• Unable to connect to sites using IIS7 Manager

  - by Phil.Wheeler

  I'm a developer who has been assigned the task of managing and configuring a new IIS7 instance on a remote server. My domain account has been added as to the local Administrators group on the box, but IIS7 has been configured to accept connections only from accounts with Windows credentials. I've added my domain account to the IIS Manager Permissions for one of my sites, but I'm still unable to connect to either that site, the IIS instance or the server in general from my local machine. There's obviously a missing element to the configuration of this setup but I don't know where to start looking. The event logs on the IIS box show audit failures for my account when trying to connect remote via the IIS7 Manager tool on my local machine. Suggestions gratefully received.

• How do I backup Credentials Manager passwords (Windows 7)

  - by Andrew J. Brehm

  I am trying to create a backup of my stored passwords in Credentials Manager. But after Windows switches to the secure desktop to get the password for the backup file it simply announced that "Your stored logon credentials could not be backed up" and gives as explanation "Element not found", neither of which is helpful. (In fact I hate the "X could not Y" type of error message). I am an administrator on the machine and there is only one password in Credentials Manager. The sole point of the backup is to create a nearly empty Credentials Manager so that I don't have to delete manually hundreds of password entries every time I have to change my domain password. (I think Microsoft haven't throught this through properly. There appears to be no way to delete more than one entry at a time.) Any ideas?

• How to get both PIPESTATUS and output in bash script

  - by Mustafa Serdar Sanli

  I'm trying to get last modification date of a file with this command TM_LOCAL=`ls -l --time-style=long-iso ~/.vimrc | awk '{ print $6" "$7 }'` TM_LOCAL has value like "2012-05-16 23:18" after execution of this line I'd also like to check PIPESTATUS to see if there was an error. For example if file does not exists, ls returns 2. But $? has value 0 as it has the return value of awk. If I run this command alone, I can check the return value of ls by looking at ${PIPESTATUS[0]} ls -l --time-style=long-iso ~/.vimrc | awk '{ print $6" "$7 }' But $PIPESTATUS does not work as I've expected if I assign the output to a variable as in the first example. In this case, $PIPESTATUS array has only 1 element which is same as $? So, the question is, how can I get both $PIPESTATUS and assign the output to a variable at the same time?

• Preventing a confirmation pop-up when updating fields in Word

  - by Gilles

  In Word 2007, an obvious candidate for updating all the fields in a range is myrange.Fields.Update But if the range is the element of ActiveDocument.StoryRanges corresponding to the footnotes, endnotes or comments, this triggers a confirmation pop-up “Word cannot undo this action. Do you want to continue?” What is this pop-up telling me about? How do I get rid of it (if it's not important)? An obvious workaround is to iterate over the fields and call each field's Update method. It doesn't fire up that question. But if I do this, what do I miss? following up to How do I update all fields in a Word document

• Google Chrome auto-clicker extension?

  - by Joel Murphy

  I'm looking for an auto-clicker that will auto click page elements in Google Chrome. Standard auto-clickers work fine, but I'd like to continue working on my computer without having to keep Google Chrome open. Does anyone know of any extensions that offer this functionality? Anything that allows me to specify an element to be clicked on, or set screen co-ordinates within a webpage and will click away until I decide to stop the script would be perfect. I've tried looking at macro extensions, but they don't seem to offer the functionality I want. Can anybody suggest a particular extension? Thanks in advance.

• Custom animation problem in Powerpoint 2003

  - by Tom Gullen

  I have an animation of a grid that scrolls to the left. It's a Gantt chart, and it works fine. I then have several elements I want to drop on the grid, I give them all the same movement animation and this works fine, everything scrolls at the same speed and time. However I want to add entrance animations for the elements on the grid, I can have it so that when all the entrance animations are complete then it starts scrolling, but I want it to enter whilst it is scrolling. How do you have an entrance animation for an element and keep it's position updated? The entrance animation and movement animation don't seem to work together as expected when run simultaneously. cheers!

• Change the spell-checking language on a PowerPoint presentation

  - by Leonardo

  I received a PowerPoint presentation with dozens of slides, each of them with a number of text boxes. Although the presentation is written in English, the language for spell checking is set to Canadian French. I’m trying to change the language to English, but even if I select all the slides and select a new element on the Language dialog box, the language of the text boxes remain the same. So I have to go slide by slide selecting the text boxes and then changing the language individually. Is there a better way to do this? The version of PowerPoint I have installed is 2002 SP3.

• How to discharge static electricity before opening a computer?

  - by Pekka

  Before opening a computer, I often hear advice to touch something that is "grounded" - a computer case for example, or a heating element - to avoid damaging the sensitive electronic equipment through static discharge. What exactly is true here, and what are the do's and don'ts. Touching what objects will actually work, and what won't? If I touch a computer case, does it matter what it stands on, and whether it is connected to an outlet? What other ways are there to protect the equipment from a static discharge than touching something grounded? Are there common pieces of clothing that I shouldn't be wearing when working inside a computer, for example a woollen pullover? There is a lot on Google, but there seem to be many contradictions and misconceptions out there, so I think this is a question worth having here.

• Download/update webpages listed in XML sitemap

  - by unor

  I'm searching a FLOSS tool that downloads all pages (and embedded resources, e.g. images) linked in a XML sitemap (built according to http://www.sitemaps.org/). The tool should "crawl" the sitemap regularly and look for new and deleted URLs and changes in the lastmod element. So whenever a page gets added/deleted/updated, the tool should apply the changes. Some sitemaps list sub-sitemaps in sitemapindex?sitemap. The tool should understand this and load all linked sub-sitemaps and look for URLs in there. I know there are tools that allow me to extract all URLs from the sitemap, so that I could feed them to wget or similar tools (see for example: Extract Links from a sitemap(xml)). But this wouldn't help in getting noticed about updates to pages. Tracking the webpages itself for updates doesn't work, because "secondary" content on the pages changes daily, but lastmod gets only updated when relevant content changed.

• Limit HTTP VERBS on Apache2

  - by user72295

  I am trying to limit the use of certain HTTP verbs on my site. I entered the following into my VirtualHost config file within the Directory element: <Limit GET POST HEAD> Allow from all </Limit> <Limit PUT DELETE OPTIONS> Deny from all </Limit> This seemed to work but with unexpected results: I ran the following telnet/HTTP commands before and after this change, open server 80 OPTIONS server/abs_path HTTP/1.1 User-Agent: Telnet/1.0 Host: server before the change I received a successful response with the Allowed headers. After the change, however, I was expecting to receive a 405 'Method not allowed' response but rather I received a 403 'Access Forbidden' response. What do I need to change in apache to return the 405 HTTP response? Many thanks

• hudson/jenkins: help needed to get started with customization work

  - by user64204

  I'm would to customize jenkins by adding links to the left hand side panel and use the pages associated with these links to serve some custom content in place of the jobs/views table displayed by default. I managed to add links to the side-bar using the sidebar-links plugin. Now I'm trying to see how to replace the content of the <td id="main-panel"> element with some custom content. The custom content is generated by some PHP scripts which ideally should be called by hudson every time the custom pages are requested, though if too complicated I can either create static content to be served by jenkins by calling my PHP scripts in a crontab or see if calls to the PHP scripts can be done by apache itself before the page requests are sent to jenkins. I'm not sure writing a plugin is the best way to proceed and I would like to have your thoughts as to how you think I should implement this.

• Disk boot failure in Windows 7 64-bit after installing the latest NVIDIA drivers

  - by Domchi

  I successfully installed the newest NVIDIA drivers (275.33) in Windows 7 64-bit and rebooted afterwards just in case. After the reboot, I got an error about missing MBR. I disconnected the slave disk so that Windows doesn't get confused and got this message: DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER It seems that Windows doesn't recognize the main disk anymore. I booted from Windows install disk but the main disk doesn't get listed as possible Windows locations to repair, and I can't get to it from the recovery prompt. The BIOS does recognize it, and I'm able to see it if I run diskpart - however "detail disk" in diskpart says that there are no volumes on the disk. I also tried bootrec /FixMbr without effect, and bootrec /FixBoot which gives the error message: Element not found. What else can I do? Why would diskpart say there are no volumes on the disk?

• Subversion LDAP Configuration

  - by dbyrne

  I am configuring a subversion repository to use basic LDAP authentication. I have an entry in my http.conf file that looks like this: <Location /company/some/location> DAV svn SVNPath /repository/some/location AuthType Basic AuthName LDAP AuthBasicProvider ldap Require valid-user AuthLDAPBindDN "cn=SubversionAdmin,ou=admins,o=company.com" AuthLDAPBindPassword "XXXXXXX" AuthLDAPURL "ldap://company.com/ou=people,o=company.com?personid" </Location> This works fine for living, breathing people who need to log in. However, I also need to provide application accounts access to the repository. These accounts are in a different OU. Do I need to add a whole new <location> element, or can I add a second AuthLDAPURLto the existing entry?

• How to configure Windows 8.1 start screen search?

  - by AlexV

  I'm using Windows 8.1 and when you are in the "start screen" (where all the tiles are), if you type something, a search panel appears on the right side with search results. In 8.0 it searched within "start menu" shortcuts and control panel elements only (if I remember correctly). In 8.1 it now search "start menu" shortcuts, my library and files and no longer control panel items. Is there a way to configure this? I use this search solely to locate a "start menu" shortcut and/or control panel element, so I would like to narrow my search to only this.

• How to change windows bootloader target folder

  - by ST3

  Here is described part of windows boot process. I would like to ask if there is a way to change boot folder, I mean to use something else instead of C:\WINDOWS. And of course that something else is a copy of Windows directory. It looks like bcdedit is good for that purpose but I'm not sure how to use that. That I want is to change path, which currently is \Windows\system32\winload.exe to \Windows Copy\system32\winload.exe Another thing I have found out is registry, HKLM\BCD00000000\Objects\{df90fe29-c40d-11e2-a7bb-92410b6e649d}\Elements\12000002::Element value is \Windows\system32\winload.exe so changing this also may be promising. But I'm not sure if I should change registry value and don't know how to use bcdedit, so any related help will be appreciated.
