  • Building a PC, advice on SSD/Hybrid Hard Drives

    - by Jamie Hartnoll
    I am looking at building a new PC, it's mainly for office (graphics heavy) use and programming. Looking for good performance with opening and closing programs and files as well as a fast boot. I plan to have 3 primary hard drives Windows 7 Programs (photoshop etc) Current Files (There'll also be a large storage capacity back up drive, but this will be the Seagate drive I already have.) So, my question is, looking at standard "old fashioned" hard drives and SSD drives, obviously there's a massive price difference. I have been looking at drives like this: http://www.ebuyer.com/268693-corsair-120gb-force-3-ssd-cssd-f120gb3-bk-cssd-f120gb3-bk and this: http://www.ebuyer.com/321969-momentus-xt-750gb-sata-2-5in-7200rpm-hybrid-8gb-ssd-in-st750lx003 Having no experience of using either I don't know what's the most efficient thing to go for. Clearly the SSD will have better performance, but: If, for example, I had an SSD for Windows (say about 100gB), that would clearly give me the boot speed I want, then I guess my real questions are: If I were to buy one more SSD, would it give the greatest improvement on standard performance if used to store programs, or currently used files? Given that the OS is on an SSD, should I not bother with the 3 drives and instead, partition that Hybrid drive to store programs and currently used files on it? Obviously, option two is cheaper and option one could cause me storage issues, but that's when I can dump files I am not currently using onto another drive. Any, I am open to suggestions... so what do you suggest?!

  • Installing WinPcap on Windows 8

    - by Dave Robinson
    I know there has been lots of discussion already on installing WinPcap on Windows 8. I'm running the RTM version. I was able to install WinPcap without a hitch by using the Windows 7 compatibility mode. Since then, I've noticed that WinPcap has stopped running and is actually no longer even installed. I tried installing it again, but now it continues to tell me that WinPcap does not work with my version of Windows. Compatibility modes and admin privileges make no difference. The only thing I remember doing to my system was installed 900MBs of Windows Updates. Does anyone have any ideas about what I might do to get WinPcap installed? I've already ensured that the compatibility mode settings I changed were in effect for all users. I've already ensured that "run this program as an administrator" is checked on the compatibility tab for all users. I've also tried installing WinPcap 4.1.2 and 4.1.1. No success with either.

  • Excessive PHP errors in Joomla

    - by Rodnower
    I have Joomla 2.5 installed on Windows 7 with Apache 2 and PHP 5. I have countless PHP errors in the log like the following: [01-Sep-2012 19:33:55 UTC] PHP Strict standards: Only variables should be assigned by reference in C:\ammon_dev\ammon\plugins\system\jquery\jquery.php on line 24 [01-Sep-2012 19:33:55 UTC] PHP Stack trace: [01-Sep-2012 19:33:55 UTC] PHP 1. {main}() C:\ammon_dev\ammon\administrator\index.php:0 [01-Sep-2012 19:33:55 UTC] PHP 2.

Joomla isn’t in debug mode, and I am sure that I’m editing the correct copy of php.ini because other changes I make to it take effect. Any ideas why I am getting so many errors or how to stop it from exploding the log?

  • Permissions Required for Sharepoint Backups

    - by Wyatt Barnett
    We are in the process of rolling out an extranet for some of our partners using WSS 3.0 as the platform. We already use it internally for a variety of things, and we are using the following powershell script to backup the server: param( $url="http://localhost", $backupFolder="c:\" ) [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") $site= new-Object Microsoft.SharePoint.SPSite($url) $names=$site.WebApplication.Sites.Names foreach ($name in $names) { $n2 = "" if ($name.Length -eq 0) { $n2="ROOT" } else { $n2 = $name } $tmp=$n2.Replace("/", "_") + ".sbk" $saveas = "" if ($backupFolder.Length -eq 0) { $saveas = $tmp } else { $saveas = join-path -path $backupFolder -childPath $tmp } $site.WebApplication.Sites.Backup($name, $saveas, "true") write-host "$n2 backed up to $saveas." } This script works perfectly on the current installation running as our domain backup user. On the new box, it fails when ran as the backup user--claiming "The web application located at http://extranet/" could not be found. That url does, in fact, work so I'm fairly certain it isn't anything that dumb and rather is some permissions issue. Especially because, when executed from my security context, the script works perfectly. I have tried making the backup user a farm owner, as well as added him to the various site collection admin groups on the extranet. The one major difference between the extranet and the intranet server is that the extranet has an alternative access mapping (for https://xnet.example.com) and also uses forms authentication for that mapping. Anyhow, what permissions (or other voodoo) do I need to setup to get this script to work properly?

  • Apache web logs "GET http/1.1" 200 error?

    - by songdogtech
    I've got some puzzling (at least to me) errors that show up in my webserver logs. What's puzzling is that they show my error page being referenced, but that error page doesn't show up as being displayed in hits on statcounter.com. Can someone tell me the difference in these two kinds of errors? Or is only one a "real" error? This is in WordPress, and I have my 404.php file in my theme redirecting to a static Wordpress page at mydomain.com/error/ These first two log entries show /error/, but a "hit" on my /error/ page doesn't show in my webstats. The page referenced - /2009/08/delete-preference-files/ - exists, and shows a "hit" at statcounter. 92.17.232.242 - - [13/Mar/2010:01:45:43 -0800] "GET /error/ HTTP/1.1" 200 4012 "http://markratledge.com/2009/08/delete-preference-files/" "Mozilla/5.0 (Windows;U; Windows NT 5.1; en-US; rv:1.9.1.8) Gecko/20100202 Firefox/3.5.8 (.NET CLR 3.5.30729)" 732 4432 92.17.232.242 - - [13/Mar/2010:01:47:11 -0800] "GET /error/ HTTP/1.1" 200 4012 "http://markratledge.com/wp-content/themes/default/style.css" "Mozilla/5.0(Windows; U; Windows NT 5.1; en-US; rv:1.9.1.8) Gecko/20100202 Firefox/3.5.8 (.NET CLR 3.5.30729)" 861 4432 These are two error entries that display my /error/ page, because /error/ gets a "hit" in statcounter.

  • Windows 7 blank dvi screen

    - by user99
    I've just upgraded to Windows 7 Ultimate 64 bit. I had an issue during installation; after setup rebooted instead of going to the 'Completing installation' screen I just got a blank screen. I eventually(!) figured out that this meant 'un-plug your second monitor to proceed'. When I did this, installation completed in a snap and everything runs fine. However, whenever I plug my second monitor into my PC, it gets no signal, the the primary monitor removes all windows. icons, the taskbar and the cursor just shows the desktop wallpaper. I'm running a GTS8800 512mb, with the latest drivers (197 IIRC). The monitors are identical, and both plug into DVI sockets on the graphics card, the only difference is I connect one using a straight DVI cable and the other using a VGA cable and a VGA-DVI converter. It's the DVI cabled one that has the issues (if I plug it in by itself it gets no signal). Everything was working fine before I upgraded to Windows 7 (I used to run XPSP2). Anyone have any ideas?

  • Regular Windows 7 BSOD with Shrew VPN client

    The Shrew VPN client appears to be a good alternative to the Cisco VPN Client on x64 Windows 7. However, since installing it I've seen fairly regular BSODs.

Superuser appears to have several recommendations for the Shrew VPN Client as an alternative to the Cisco VPN client on 64 bit machines, so I wondered if anyone here has seen this problem and possibly found a solution to the problem? I've decided to run the VPN client under Windows 7 compatibility mode for the moment (Vista SP2) with administrator privileges to see if it makes a difference. Oddly, the VPN doesn't necessarily need to be connected. I've noticed it when browsing using Google Chrome and Internet Explorer, usually when I open up a new tab. If it carries on I think I'll be forced to shell out the 120 EUR for the NCP Client instead.

  • Some HTTPS connections via NAT fail, but work on firewall itself.

    - by hnxn
    Hi, I am having trouble establishing some HTTPS connections from internal machines, even though these same connections work if initiated on the firewall itself. The firewall machine is running Ubuntu 10.04.1 and shorewall 4.4.6. The internet connection is Bell PPPoE DSL (in Canada). I have tried various MTU settings, it doesn't seem to make any difference. Other protocols (HTTP, FTP, etc) generally work. The problem seems to be limited to certain sites; this one never works from an internal machine, but always works from the firewall itself: From internal machine: $ wget https://images.fedex.com/images/ascend/shared/headers/nxgen/corp_logo.gif --2011-01-13 20:51:31-- https://images.fedex.com/images/ascend/shared/headers/nxgen/corp_logo.gif Resolving images.fedex.com... 184.24.96.69 Connecting to images.fedex.com|184.24.96.69|:443... connected. ^C From firewall: $ wget https://images.fedex.com/images/ascend/shared/headers/nxgen/corp_logo.gif --2011-01-13 20:58:28-- https://images.fedex.com/images/ascend/shared/headers/nxgen/corp_logo.gif Resolving images.fedex.com... 184.24.96.69 Connecting to images.fedex.com|184.24.96.69|:443... connected.

  • Building a PC for Work and play? [closed]

    - by Derek Organ
    Ok, Its been a long time since I build my own PC so I'm looking to get back into it again and build a new one. First off budget is about €800 excluding the monitor and windows 7 licence and mouse. (just bought a new g500) I plan on using my computer for work, lots of applications open at once but none particularly excessive (photoshop being the most demanding, mostly coding tools) I also use it for some gaming, e.g. COD, Starcraft etc. One thing I do want to do eventually is get a really good monitor with hight resolution and maybe 27" so the graphics card needs to be able to make best use of that. So a few questions 1) Is the bottle neck in performance mostly still the harddrives? 2) Aren't most processors e.g. i5 etc even i3 so far a head of other bottlenecks it makes litte difference the higher you go. Isn't the Graphics card dealing with heavy graphics so what really slows because of a slow CPU? So from this my thinking is to get a SSD drive as my primary drive for OS etc and have loads of memory e.g. 6-8GB and a decent mid level graphics card? It doesn't seem at my level worth spending much on CPU and any other parts really. I basic parts off the top of my head Case, Motherboard CPU SSD Drive SATA Drive Power Supply Memory Cooling (fan?) Graphics Card Network Card Keyboard DVD drive Mouse Windows Monitor Am I missing anything? Any helpful tips or general education much appreciated. Thanks, Derek

  • Error - "IR Hardware not detected" - but it's installed/working

    - by Robert
    I am trying to do: Settings-TV-Set up TV signal. During this process I am getting the error "IR Hardware not detected." With the remote, I can select the "try again" button (to re-detect) and it tries again, so the remote works. Plugging in the "IR blaster" doesn't change anything. (I wouldn't expect any difference, but I read a post which said you needed that. I will get Media Center to change channels if I can get that working - but first things first.) I was able to do the setup months ago when I had cable. and everything was fine. I just got DirecTV. (BTW - During the above process, Media Center detects the signal coming in on channel 3. Windows XP Media Center SP3. The TV Tuner card is a Pinnacle TCTV HD PCI. Everything - and I mean everything - has the latest firmware and drivers - as of 4 months ago when I fixed a different problem. So I DON"T WANT TO HEAR the standard answer to check drivers/firmware. THANK YOU.) Thanks for any help.

  • AMD Fusion GPU passthrough to KVM or Xen

    - by BigChief
    Has anyone successfully gotten a passthrough working with the GPU portion of AMD's Fusion APUs (the E-350 is my target) on top of a Linux hypervisor? IE, I want to dedicate the GPU to one VM only, excluding all other VMs as well as the host. I know PCI passthrough can work with patches / kernel rebuilds for Xen and KVM. However, since the GPU is on the same chip, I don't know if the host OS will see it as PCI. I know there are a number of tangential issues here, such as: Poor Fusion drivers in Linux at the moment Unsuccessful patching efforts seem common VT-d / IOMMU is required and (from my reading) is supported on the APU, but the motherboard may not offer it KVM doesn't appear to support primary graphics cards, only secondary graphics cards (described here) However, I'd like to hear from anyone who has messed with this, even failed attempts. Fedora + KVM is my preferred virtualization platform but I'm willing to change that if it makes a difference. EDIT: The goal is to do this for a Windows 7 guest (I know it's asking a lot). Regardless, just assume this is HVM, not PV.

  • MOSS2007 tries to use ActiveDirectory when I have configured an alternative membership provider

    - by glenatron
    I've got a MOSS site that I am trying to configure using Forms authentication and absolutely any kind of membership provider whatsoever. Thus far ActiveDirectory has proved obstructively difficult so I've just whipped up a simple stub membership provider and put it in the GAC. It's a very basic and simple provider but it works fine with an ASP.Net site, I just can't make it work with Sharepoint. On Sharepoint I get the following error when I look for StubProvider:Bob ( or anything else for that matter) from the "Policy For Web Application" people picker: Error in searching user 'StubProvider:bob' : System.ComponentModel.Win32Exception: Unable to contact the global catalog server at Microsoft.SharePoint.Utilities.SPActiveDirectoryDomain.GetDirectorySearcher() at Microsoft.SharePoint.WebControls.PeopleEditor.SearchFromGC(SPActiveDirectoryDomain domain, String strFilter, String[] rgstrProp, Int32 nTimeout, Int32 nSizeLimit, SPUserCollection spUsers, ArrayList& rgResults) at Microsoft.SharePoint.Utilities.SPUserUtility.SearchAgainstAD(String input, SPActiveDirectoryDomain domainController, SPPrincipalType scopes, SPUserCollection usersContainer, Int32 maxCount, String customQuery, TimeSpan searchTimeout, Boolean& reachMaxCount) at Microsoft.SharePoint.Utilities.SPActiveDirectoryPrincipalResolver.SearchPrincipals(String input, SPPrincipalType scopes, SPPrincipalSource sources, SPUserCollection usersContainer, Int32 maxCount, Boolean& reachMaxCount) at Microsoft.SharePoint.Utilities.SPUtility.SearchPrincipalFromResolvers(List`1 resolvers, String input, SPPrincipalType scopes, SPPrincipalSource sources, SPUserCollection usersContainer, Int32 maxCount, Boolean& reachMaxCount, Dictionary`2 usersDict). The Provider is named as Authentication Provider for the Site Collection in question. As far as I can tell this is because Sharepoint is still trying to access ActiveDirectory rather than talking to the provider I'm asking it to use. My Sharepoint Central Administration section includes this: <membership> <providers> <add name="StubProvider" type="StubMembershipProvider.Provider, StubMembershipProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=5bd7e2498c3e1a03" /> </providers> </membership> And also: <PeoplePickerWildcards> <clear /> <add key="StubProvider" value="%" /> </PeoplePickerWildcards> Is there a clear reason why this would not be accessible from the PeoplePicker or why it is still trying to use ActiveDirectory? I've made sure I reset IIS and even restarted the server to see if either of those helped but they made no difference.

  • Using GUI ftp on Win7 and Vista without additional software

    - by Stephen Jones
    Goal: provide a 'no-software' method for 'less technical' users to access password protect ftp location from Win7 and Vista (existing approach for WinXP works). 'No software' method to mean without installing additional software (e.g. FileZilla, WinSCP) - the solution is supplied to external non-technical users. WinXP (works): Using Windows Explorer, WinXP supports non-technical ftp access by pasting: ftp://username:[email protected] into the address bar. The remote ftp site's files / directory structure becomes available and can be copied to / from easily (in the style of local file copy / paste) by a 'less technical' user. Win7 / Vista (doesn't work): Pasting the same URL into the Windows Explorer on Win7 or Vista causes an error: An error occurred opening that folder on the FTP server. Make sure you have permission to access that folder. Details: The connection with the server was reset. Notes: a) The same username/password/server typed from the (DOS) command line achieves access to the server, but this is a more 'technical' solution than desired. I am looking for a WinXP equivalent solution. b) Under 'Control Panel' / 'Internet options' / 'Advanced' tab - the boxes for 'Enable FTP folder view' and 'Use Passive FTP' are ticked (enabled) c) Adding an inbound firewall rule for local port 20 (TCP) was attempted with no difference in results (i.e. failure)

  • CentOS iscsi initiator has session but there is no block device

    I have installed the scsi-target-utils package on CentOS and I used it to perform a discovery. The discovery did give me an active session. I restarted the iscsi service but I do not see any new devices (fdisk -l). I see in /var/log/messages that my connection is operational now. I'm not sure how to debug this further.

  • BIND - why duplicate nameserver entries (@ and *)?

    - by user27465
    I had to manually tweak my DNS service providers BIND file. BIND file, created by professional hosting company, before: $ORIGIN mycoolsite.com. $TTL 300 @ SOA ns1.cheapreg.com. registry.cheapreg.com.

Any reason I should also duplicate nameserver entries (@ and *) ?

  • Can't connect to research.microsoft.com on home Qwest DSL connection

    - by rakingleaves
    I have a puzzling issue regarding accessing research.microsoft.com from my home Qwest DSL connection. By default, I frequently get timeouts when accessing research.microsoft.com from Firefox, Safari, or Chrome on my Mac. I also cannot access the site from Internet Explorer in a Windows VM. However, I am able to access the site through proxify.com, so I know the site is not down. Furthermore, I haven't noticed problems accessing other sites (in particular, www.microsoft.com works fine). Also, I can access research.microsoft.com when I'm connected to networks other than my home Qwest DSL connection. Together, the above make me suspect a problem with either my router (Airport Express) or, more likely, my ISP. Anyone have any thoughts on how I can narrow down the problem further? I could call my ISP and tell them the above, but my feeling is that probably won't get me very far. I can get by browsing research.microsoft.com through a proxy, but it would be nice to figure out what's going on here and fix the problem. Oh, the only relevant discussion I found via Google was here: http://forums.whirlpool.net.au/forum-replies-archive.cfm/1311734.html Update: Thanks to those who have tried to help! I found one other thing while Googling that may be vaguely relevant: http://thedaneshproject.com/posts/supportmicrosoftcom-not-working-behind-squid/ Disabling the Accept-Encoding headers in Firefox actually didn't make a difference for me. I just thought the above might spark some other ideas about how mishandling of HTTP headers somewhere might be causing this problem. Thanks again! Another update: In case anyone is still thinking about this; I've found that I can't surf research.microsoft.com using the links text-based browser, but I can reliably download individual files with wget. Maybe that helps?

  • How to calculate RAM value on performance per dollar spent

    - by Stucko
    Hi, I'm trying to make decisions on buying a new PC. I have most specifications (processor/graphic card/hard disk) pin-downed except for RAM. I am wondering what is the best RAM configuration for the amount of money I'm spending. As the question of best is subjective, I'd like to know how would I calculate the value of RAM sticks sold. 1.(sample)The value of amount of memory: 1) CORSAIR PC1333 D3 2GB = costs $80 2) CORSAIR PC1333 D3 4GB = costs $190 would it be better to buy 2 of item 1) instead of 1 of item 2) ?? Although I would normally choose to have 1 of 2) as the difference is only (190-(80*2)) = 30 as I would save 1 DIMM slot, What I need is the value per amount: 1) 80/ 2 = $40 per 1GB 2) 190/ 4 = $47.5 per 1GB 2. The value of frequency: 1) CORSAIR PC1333 4GB = costs 190 2) CORSAIR PC1600C7 4GB = costs 325 Im not even sure of the denominator ... $ per 1 ghz speed? 3. The value of latency: 1) CORSAIR CMP1600C8 8-8-8-24 2GBx3 (triple channel) = costs 589 2) CORSAIR CMP1600C7D 7-7-7-20 2GBx3 (triple channel) = costs 880 Im not even sure of the denominator ... $ per 1 ghz speed? Just for your information i'd like to get the best out of the money im going to spend to put on a 6 DIMM slot i7core motherboard.

  • "Safe" personal router use on apartment-wide network

    - by noisetank
    I recently moved into an apartment with internet included in my rent. This was a boon at first, but now I'm feeling limited. To get devices connected (wired or wireless), I have to whitelist the MAC addresses on mycampusnet.com. This is annoying (considering I'm well over the 10 device limit including my roommate's stuff), but what's really driving me mad is that I don't seem to have any semblance of a "local" network. I've relied heavily on static IPs and port forwarding in the past (accessing NAS and remote desktop) and (as far as I can understand), that functionality is nonexistent without my router set up. Also, as my wired and wireless devices don't always seem to make it onto the same subnet, I'm unable to use any of my iDevices with my Apple TV (I can, however, mirror to no less than four strangers' Apple TVs at any moment, which is a whole other level of discomforting). I've talked to the head of the apartment complex and she told me that they personally don't have any issue with my using a router, but the provider (CampusConnect) does not currently allow it. Apparently, enough people have put in complaints/requests about the restriction (the apartments are for graduate students and University staff, many of which need to set up things like VPNs for work reasons) to open up some sort of ticket to get the functionality in place, but all the calls I've made to get status updates have been a waste of time. My question is: If I plugged my router into the apartment network, what would happen? I've been told already that personal routers would "interfere with the wireless" and that they would shut my port down if I used one, but is that a legitimate thing or just something made up that sounds real to keep the average Joe from pushing it further? I'm guessing there's some way of configuring my router to keep it from disrupting the rest of the network, but it's not something they want to tell me for obvious reasons. Am I right? And if so, what are the chances that they'd notice the difference in traffic or whatever and shut off my port?

  • Trouble cloning a Macbook Pro hard drive

    - by Mirko Froehlich
    I am trying to upgrade the 250GB hard drive in my MacBook Pro (early 2008 model) to a 750GB drive. I have connected the new drive via an external USB enclosure. The drive is recognized fine, I can format it, etc. However, every time I try to clone the drive, I am getting Input/Output errors. Before the clone operation, I have verified both the internal and the external drive using Disk Utility, and they both check out fine. After the clone operation, the external drive shows multiple "Invalid node structure" errors: I have tried two approaches for cloning the drive: Using Disk Utility, by starting from the OSX install DVD Using Carbon Copy Cloner The outcome is the same in both cases. The Carbon Copy Cloner logs show a handful of the following types of errors: rsync: mkstemp "<... an external filename ...>" failed: Input/output error (5) rsync: stat "<... an external filename ...>" failed: Input/output error (5) The actual files affected seem to be different across different runs of the application. Before the last run, I used Disk Utility to (once more) reformat the external drive and explicitly overwrite it with zeros, but this made no difference. I also tried running a surface scan in Tech Tool Pro overnight. It got about 2/3 of the way through before I had to disconnect the drive (had to take my MacBook Pro to work), but so far it didn't report any bad blocks. Assuming it scans the drive in the same order in which blocks would be allocated during actual use, it seems like if bad blocks were to blame for the clone failures, they should have been found already (given that the source drive is only 250GB). As a last attempt, I may try SuperDuper as well, although my understanding is that it uses the same underlying rsync approach as Carbon Copy Cloner, so it's unlikely to perform any better. Are there any other things I should try before I send the drive in for a replacement? Could these problems be caused by my internal drive, even though it works fine and checks out fine in Disk Utility?

  • eAccelerator Issue - Cache Directory Empty.

    - by Tom
    Hi all, Hoping someone can give me a hand with this. I've recently installated eAccelerator 0.9.6.1 - On a CentOS LAMP server. Had it working fine, using the /tmp/accelerator as the cache directory. php.ini set up: zend_extension="/usr/local/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so" eaccelerator.shm_size="200" eaccelerator.cache_dir="/var/cache/eaccelerator" eaccelerator.enable="1" eaccelerator.optimizer="1" eaccelerator.check_mtime="1" eaccelerator.debug="0" eaccelerator.filter="" eaccelerator.shm_max="0" eaccelerator.shm_ttl="3600" eaccelerator.shm_prune_period="180" eaccelerator.shm_only="1" eaccelerator.compress="1" eaccelerator.compress_level="9" php -v output: PHP 5.2.12 (cli) (built: Feb 3 2010 00:34:28) Copyright (c) 1997-2009 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies with eAccelerator v0.9.6.1, Copyright (c) 2004-2010 eAccelerator, by eAccelerator with the ionCube PHP Loader v3.3.20, Copyright (c) 2002-2010, by ionCube Ltd. I had to remove the cache directory as I was testing something. Remade it, re-set permissions and found that eAccelerator was no longer creating cache files within the folder. I thought it might be down to ownership rights on the folder so chown'd it apache.apache and this made no difference. I recreated the directory in /var/cache instead and editted php.ini to point to the new cache dir location, chmod'd, chown'd etc. and still eAccelerator is not creating any of the cache files in the directory (just empty). Could someone suggest what I might be doing incorrectly here. I've read through numerous pages to try and troubleshoot the issue to no avail. Any help appreciated.

  • Destroyed user account on OS X with dscl; how to restore? [migrated]

    - by Sam Ritchie
    I was trying to create a new user on my OS X Lion machine, and somehow managed to destroy my own user's account. Here are the steps I took; hopefully someone here can recognize what I did, and maybe identify some way around this. First, I ran these commands: sudo dscl localhost -create /Local/Default/Users/elasticsearch sudo dscl localhost -create /Local/Default/Users/elasticsearch /bin/bash # mistake! sudo dscl localhost -create /Local/Default/Users/elasticsearch UserShell /bin/bash sudo dscl localhost -create /Local/Default/Users/elasticsearch RealName "Elastic Search" sudo dscl localhost -create /Local/Default/Users/elasticsearch UniqueID 503 # MY uniqueID sudo dscl localhost -create /Local/Default/Users/elasticsearch PrimaryGroupID 1000 sudo dscl localhost -create /Local/Default/Users/elasticsearch NFSHomeDirectory /Local/Users/elasticsearch The big mistake I made here was using "503", which was my user's UniqueID. Immediately my shell username changed to "elasticsearch". I fiddled around, tried to change the current user with sudo su -u sritchie, but this didn't work. On restart, only the "Elastic Search" user was available. I logged into the Lion Recovery partition and reset the root password. After logging in as root and checking on the terminal, I made the remarkable discovery that my home folder was totally empty. I deleted the elasticsearch user, but it made no difference. I don't see anything in Deleted Users either. The odd thing is that when I log in now as myself (sritchie) I can see desktop icons with previews. I can even open a few text files from the Downloads folder if I use the dock alias to Downloads. Could this data be hiding somewhere? Any help would be REALLY appreciated! Thanks, Sam

  • Troubleshooting a Windows 7 PC that wouldn't sleep

    - by NPE
    I have a new Windows 7 PC that wouldn't sleep (not just automatically, but also when specifically told to). The screen goes black momentarily, but within two seconds the machine comes back as if nothing has happened. I tried powercfg energy. This produces some errors quoted at the bottom of this post, plus some warnings about timer resolution. There are no USB devices connected other than wireless keyboard + mouse (Logitech MK250); I tried unplugging them to no effect. The motherboard is Asus P7P55D-E. powercfg lastwake says "Wake History Count - 0", which I take to mean that it never actually went to sleep. I dual boot into Ubuntu, and was having exactly the same problem on the Linux side. That turned out to do with USB 3.0, which I've now disabled in the BIOS. This has solved the problem on the Ubuntu side of things, but made no difference to Windows 7. Any suggestions? Suspend:USB Device not Entering Suspend The USB device did not enter the Suspend state.

  • backup of TFS with DPM 2007 - different backup times

    - by user46516
    I have DPM set up to back up my TFS server every 30 minutes, the reason being it's a way better interface than the quirky SQL backup interface. I also do a full backup nightly using an SQL maintenance job. My thinking is I would use DPM to restore my databases in case of losing my database and the nightly full backup would be a "just in case" the DPM restore doesn't work. I was thinking a little harder about this set up today and started to think about the fact that the DPM backup of the individual databases happens at different 30 min windows.. i.e. one happens at 13h30, another at 13h34 etc. Would this difference in time be a problem when it comes to restoring the TFS server? If I restore the databases and they are from different times, will this create corruption with pointers in one database pointing to missing items in the other database.. do the databases even rely on each other or are they completely interdependant. Lastly, how would SQL (log) backup cope with this?

  • How would I force Debian to use the physical sector size on a hard disk?

    - by Confused User
    I just purchased a few new 3TB WD drives. These have physical 4k sectors, but there is some sort of layer which is providing 512B logical sectors (see the partition table below). In order to attempt to get some more speed out of my hard drives, I would like to get rid of this logical layer and actually use the physical 4k sectors. However, I can't figure out how to do this (or even if it's possible) from the man pages of fdisk and parted, or from searching Google. Does anybody know how this could be done? As to why this is relevant, this page demonstrates that meerly aligning the sectors properly can already make up to a 25% speed difference for reads, and more than 2500% for writes in some cases! Getting rid of the logical sectors in favor of the physicals ones should improve speeds even more. Thanks! $ parted /dev/sdc GNU Parted 2.3 Using /dev/sdc Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Model: ATA WDC WD30EZRX-00M (scsi) Disk /dev/sdc: 3001GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 3001GB 3001GB zfs 9 3001GB 3001GB 8389kB P.S. I don't care about the data on the drives, I was just playing with different file systems. Also, this is my first time posting here, so please let me know if my posts should be formatted differently, etc.

  • Fix Linux-made png file for use on Windows

    - by BGM
    There is a particular icon library that I really like. Now, I have downloaded the package that has the png files inside (I know the ico files are there, but I want the png files). However, about my Windows 7 computer tells me that about 1/3 of the png files are corrupt. I usually use XnView to view the files, and it won't display the "corrupt" files. I've tried other editors and viewers and I get the same issue. Now, the png package was originally designed for Linux to be an OS-icon-package for the entire system, so I figure the png files were built in Linux. So, is there a way I can "fix" the "corrupted" png files for my Windows 7 computer? Maybe when the files were created there was some bit that was off-colour or something? Any clues? [edit] I have read in this thread that the "corruption" could happen during the extraction process. I did all the extraction with 7-zip. It was a zip containing a tar. I will try another extractor, but I don't think it will make any difference.
