  • Backup solutions for Rackspace Cloud Sites

    - by Daniel A. White
    What options do I have for backing up the content from a Rackspace Cloud Sites including files and databases? I know they have cron jobs, but I am not sure what options I have when it comes to that. Here are some of the things the Cron jobs they support. http://cloudsites.rackspacecloud.com/index.php/How%5Fdo%5FI%5Fschedule%5Fa%5Fcron%5Fjob%3F

  • Possible to capture and re-broadcast as RTMP?

    - by Jeremy White
    I may have a need coming up soon to capture a live video broadcast stream and re-broadcast it as an RTMP stream for playback in Flash Player. Is this possible? I'm seeing posts online from 2005 to 2009 claiming that RTMP either isn't or is poorly supported in VLC. I do not currently know what format the incoming video stream will be -- will update when I get that information.

  • Windows 7 mapped drive kicking off OS X users

    - by Collin White
    I've mapped a network drive on my Windows 7 PC at my office. The windows machine has a few TB of storage that is being accessed by my development team (all running mac os 10.7). The share seems to work fine for a little while but will timeout and kick the mac users off and sometimes disallows a connection on the next attempt. Restarting the windows machine fixes the problem. I've tried this tutorial as well as setting the maximum session length in the Local Security Policy section to 99999 (I discovered 0 did not mean unlimited, only a 'reasonable ammount of time') anyway, the setting is now for ~208 days which is sufficient (see attached). I'm having trouble debugging this in general so if anyone has some pointers I'm all ears. This is a intermittent issue which in my opinion are the hardest kinds to debug. If anyone knows of how I might monitor connections from the PC that would also be pretty cool. Previously the files were hosted on a mac mini and everything was working just fine (the mini just didn't have the ability for the storage capacity we needed) so I believe it is some windows setting that is kicking users off. Anyway, thanks for reading.

  • How to prepare WiFi for an on-stage demo?

    - by Jeremy White
    Today at WWDC, Steve Jobs gave his keynote and ended up having a failure on-stage when connecting to WiFi. Google had a similar issue a few weeks ago in the same conference center. Please reference the following article for more information. http://news.cnet.com/8301-31021_3-20007009-260.html I am looking for information on how to best prepare a demo which uses a closed wireless network in front of a large audience. Note that the network will be closed, and will not require internet access. What steps can I take to prevent interference from existing WiFi, Bluetooth, etc? How can I best prevent curious/malicious people from trying to intrude on my WiFi network? I am open to recommendations on specific models of routers.

  • Fuzzy Sound / Crackling

    - by Walter White
    Whenever I play music through my headphones on my laptop, I get a little bit of fuzz or cracking that is noticeable at lower volumes. When I listen through my phone, the sound is much clearer, both when music is playing and nothing is playing. The noise is more noticeable with my Sennheiser 280 PRO headphones than with earbuds. Is there anything I can do to improve audio playback on my laptop? I am surprised that the audio quality is better on my phone than my laptop which should have better hardware.

  • Logging with Resource Monitor?

    - by Jay White
    I am having sudden spikes in disk read activity, which can tie up my system for a few seconds at a time. I would like to figure out the cause of this before I set my machine to go live. With Performance Monitor I know I can log activity, but this does not show me individual processes that cause a spike. Resource Monitor allows me to see processes, but I have no way to keep logs. It seems unless I have Resource Monitor open at the time of a spike, I will not be able to identify the process causing the spike. Can someone suggest a way to log with Resource Monitor, or an alternative tool that can?

    Please help!, Here is my situation: I've been doing business using my current gmail address ([email protected]) and really wanted my mail address to read [email protected], so i looked into google apps. It says you can set up custom emails with your domain name, achieving the above goal, but how do i configure these addresses to run through my CURRENT gmail account? I have everything pretty well set up, and it would be very time consuming to effectively start again...Any help would be greatly appreciated. Many thanks. Barney

  • Windows 7 Home hangs at "Welcome" screen

    - by White Phoenix
    I'm asking on behalf of a friend who's currently having problems with his machine. Windows 7 Home 32-bit. He's too far away for me to help by going over to his house - I'm helping him over the Internet. This is his current machine: http://www.newegg.com/Product/Product.aspx?Item=N82E16883227134 The only two changes he made to that machine is to swap out the gfx card for a EVGA GTX 460 and the PSU for a Corsair TX650. Here's what happened: He was playing a computer game (fairly CPU/GPU intensive) and had some music going in the background in foobar while playing. Suddenly, he notices the music stopped playing, so he switches to foobar to try to close it, but it freezes up (window won't respond). So he figures it's just foobar having a bad day and force quits that program. Suddenly, his game won't respond, so he force quits that, then the entire computer just went to crap at that point, so he hits the restart button on his machine. Computer POSTS fine, but now he gets stuck at the Windows "welcome" screen (his account is set to auto-login). HD activity light is solid yellow but he doesn't hear HDD activity. He tried booting into Safe Mode - gets stuck at the "welcome screen". Tried a STartup Repair within Windows 7, it found a few problems, but still gets stuck at welcome. I advised him to boot off the DVD - sfc /scannow found nothing (couldn't use the regular /scannow option; says there's a repair pending, had to use use offbootdir/offwindir command switches). Ran startup repair 3 times - found nothing. My friend runs virus/malware scans on a regular basis, so he's fairly sure it's not that either. Right now I'm having my friend run chkdsk /R on the computer while in this Startup Recovery mode - so far it's caught a few bad sectors. However at this point I'm kinda wondering which way to go if chkdsk doesn't fix it. Quick Google search said someone had success by booting Windows with bootlogging on - some others have success with running the aforemented chkdsk, etc. The fact that Windows cannot even boot into Safe Mode concerns me. While we're waiting for chkdsk /R to finish, are there any other options I can give my friend short of reinstalling Windows 7? He has his data on a separate partition so that's not a major problem (though it'll be an annoyance for him). I suspect his hard drive may be having some issues, but my main concern is getting him back up and running before we start diagnosing the hard drive (I may have him run some sort of SMART test utility later).

  • Where should I plug in my monitor -- Motherboard or Graphics card?

    - by Jeremy White
    Assuming I am using the following equipment... motherboard with HDMI/DVI & no embedded graphics discrete graphics card (nVidia or ATI) on PCI-E slot Intel CPU with integrated graphics ...where should I plug my monitor into the computer? Presumably, I'll get the fastest speed on games connected directly to the graphics card. But there is also power savings when connecting to the motherboard and accessing the Intel on-board graphics. I've read that some motherboards can switch automatically between the Intel graphics and discrete graphics. Is that something that works well, and where do I connect the monitor to enable that?

  • Graphics card artifacting

    - by White Phoenix
    This is my current build: EVGA X58 (first generation) motherboard Intel i7 965 @ stock clocks 3x 2GB DDR3-1600 Corsair RAM at stock timings and voltages Corsair AX750 80 Plus Gold PSU 1 Optical Drive 1 Seagate 7200.10 500 GB drive 2x Western Digital Caviar Black 1 TB drives OCZ Vertex 1 60 GB EVGA GTX 460 Antec 1200 case HT-Omega Striker 7.1 Sound Card Windows 7 32-bit Professional (PAE Enabled) My graphics card started artifacting while I was playing a game. It artifacted, the display blinked, then I got an NVIDIA driver has crashed and recovered message. Kept going, more artifacts, another crash, but this time my display blanked out and I couldn't do anything. Restarted my computer - artifacting is in the BIOS - got to Windows 7 but it BSOD'd before I could even log in. I restarted the computer again - artifacts cleared themselves out and I managed to get to Win7, but it soon started blinking in and out and artifacting again. Checked the card temps and they're well within range. (50 idle, 70 full load) The ambient temperature here is about 80-85F with high humidity. Tried Safe Mode and it still froze up/BSOD'd. Already tried the following to fix this problem: - Reseat the graphics card and swapped in a different slot. - Removed cover on card and sprayed with compressed air to clean it out. - Swapped around memory and/or went with only using one stick at a time. - Underclocked card I called EVGA Tech Support and they said that the voltage on the 12V rail of my Corsair AX750 PSU was on the high end of the "acceptable" range (12.4V, highest within acceptable range is 12.6V - optimal is obviously 12V). They gave me an RMA number anyway, but I want to get a second opinion from you all before I send this thing off, as shipping from where I live to EVGA is kind of pricey. This PSU is only 6 months old. So that I don't have to play RMA tag, which case would be most likely? I'm strapped for cash at the moment so I want to reduce the amount of RMAs I have to do since shipping is expensive here. Is there any surefire way to test to see if it's really the graphics card or the PSU? I tried unplugging any devices that were connected to the 12V rail (except for my SSD and graphics card) as I do have 3 mechanical hard drives, but the voltage for that rail didn't drop (it remained at 12.4V). I'm fairly sure it isn't the drivers since I'm getting the artifacting at the BIOS too. Right now I'm back in Windows 7 but I don't know for how long until it messes up again. Any ideas?

  • How to version large binary files?

    - by Walter White
    I run Windows XP inside a virtual machine for some tasks. I attempted to use git to version the image for virtual box; however, it is about 6GB after all the service packs. I only have 6GB of ram and git bombs out saying it is out of memory. I would basically like to have snapshots of Windows so that I can simply blow away an image and start anew when I want to. I like to have something I can rollback to in the event that an upgrade doesn't work so I would prefer to use version control or snapshots if the filesystem supports it. Any ideas on what tools I can use to do that?

  • GPU Temperature comparisons between similar GPUs of the same line

    - by White Phoenix
    As a general rule of thumb, if there are two similar GPUs from the same line (i.e. an NVIDIA GTX 260 vs a NVIDIA GTX 280), will the less powerful or more powerful GPU run hotter? This is assuming all other factors stay the same - hardware configuration, cooling setup, ingame settings, etc. Or does this depend entirely upon the GPU itself? I do remember reading that the GTX 280 in this example was terribly inefficient with power and cooling.

  • Comparison of Unix shells

    - by Andy White
    Of the major Unix shells (bash, ksh, tcsh, zsh, others?), are there any compelling reasons to use one over another? Which is the most interactive/command-line friendly? Which is the most conducive/intuitive for writing scripts? Are there any major built-in features that one shell offers that others don't? Are any of these shells really good for one type of function, but not another? Or are they all pretty well-rounded/flexible? Is it just a matter of personal preference? I can make this community wiki if anyone prefers.

  • git - recover deleted files from a prior commit

    - by Walter White
    I accidentally deleted some files in a prior commit and would like to recover them. How can I do this? I ran this and found exactly what I was looking for: git whatchanged --diff-filter=D At the time I made the commit, I should have committed the new/changed files only and ran a reset --hard then to recover the missing files. I have about 100 files that I need to restore. I don't want to do a straight revert as that will also undo the changes in that commit. Any ideas?

  • WD: UDMA CRC Errors and Reallocated Sector

    - by Leo White
    I got a WD Caviar Black 1TB (WD1001FALS) and according to SMART, I got: one "Reallocated Sector" one "Reallocated Event" 26 UDMA CRC Errors in my drive but it's a "Pass" for the "SMART overall-health self assessment test". I think it's because of these, I'm having problems with Grub, and thus can't boot into any OS at all. Are these problems serious? According to "Warranty Services", my drive is still "In Limited Warranty". Would I be eligible for a replacement? FYI: I'm running Ubuntu 11.10. Any help will be appreciated. Thanks

  • Unable to SSH into ESXi 4.1 host - "Access Denied"

    - by Andrew White
    I am unable to SSH into an existing ESXi server. I have a user which is in the "root" and "users" group and is able to connect via vSphere. However after enabling "Remote support (SSH)", attempting to connect by putty and entering my username/password when prompted I am presented with an "Access Denied" message. I have run through the options presented at this KB article to no avail. I have taken down the firewall on the machine (it is remote) temporarily to check if this helped - no change. The username/password are definitely correct and I can obviously get connectivity if I am presented with the username/password prompt. I am at a bit of a loss what else I can try. Thanks all

  • htpasswd and htaccess in Plesk 9.3

    - by J White
    Greetings Here is my situation. I currently have one website on my dedicated server. As of now, I have protected the directory /exclusive using the Plesk control panel. I am having a billing company install their password management script on the server but they need the absolute location to the .htpasswd file. I can't find it or the .htaccess file. Would it be easier to unprotect the /exclusive directory and create the .htaccess file in notepad? If this is done, where should I place the .htpasswd file? -jw

  • BYOD (accessing files) on a domain without joining?

    - by Philip White
    I run a Samba 4 instance at a small private school. This makes a regular Linux server appear as a directory controller. There are two relevant benefits to this: I have a Samba share for people's documents, and I use the Redirected Folders feature to allow any employee to sit down at any PC, log in with their domain credentials, and their My Documents points to network storage. Everyone has a mapped drive (using Group Policy Preferences) to a share specific to their account type. Students can access one share (one share for all students), teachers have another, and office staff have another. However, I would like to allow BYOD (Bring Your Own Device). Some employees are already asking for it with their personal laptops, and I know eventually most everyone will want to. Is there any way to replicate the two features above without having to join PCs to the domain? Joining personal PCs is impractical if only because only professional editions of Windows support this. Ideally, any operating system (including mobile) could access the relevant shares, but of course Windows is key. Offline caching is optional. (I could set up OpenVPN for teachers who want to access their files from home.) The problem with simply giving SSH access to the relevant shares is primarily that Samba 4 relies on ext4 ACLs and ext4 extended attributes to maintain NTFS permissions. Writing files directly to the Linux server would bypass this and would (probably) not be interoperable with Samba4. Right now I am completely flexible. I am even fine with scrapping the whole domain and using some other software for the two features above. How can I allow school employees and students freedom to securely share files without requiring everyone to have specific editions of Windows?

  • Configure Web app for external access (IIS7), allowing only certain users via AD group. All users need internal access

    - by White Island
    We have a Web app running in IIS7 (Server 2008 R2). I now need to allow external access with an SSL certificate, so certain users (e.g. the owner of the company) can use it remotely without VPN. They want to roll out the external access only to those specific users at first (thinking: a Windows credential prompt), BUT everyone will still need access internally (HTTP), without the prompt. I have the SSL cert installed on the server and public DNS configured. I've been trying to figure out how to work the authentication/authorization. I was thinking I need to disable Anonymous authn and set Windows authn, then I keep coming back to 'URL Authorization' in my research for the group setting; however, when I tried URL authz, (removed allow all, added allow rule for the special group), it broke the site internally (403.2 Forbidden, I believe it was). I thought maybe setting up a second site in IIS pointing to the same program would work, but the exact same thing happened (and again with a new app pool, just for kicks). So I guess my question is, how would you do this: allow external access, limited to users in a specific AD group, while still allowing internal access without a credentials prompt? How do I separate the external HTTPS and internal HTTP authorization requirements? Will I need to just copy the entire contents of the app in Windows Explorer to a new folder and create my external site from that? Is Windows authentication the correct option for this? I did come across this, which refers to creating a custom module. While it sounds like a solution, it's not one I'm familiar with, and I just wondered if there is a simpler way to get it to work: http://forums.iis.net/p/1182792/2000775.aspx Thanks!

  • Dealing with huge SQL resultset

    - by Dave McClelland
    I am working with a rather large mysql database (several million rows) with a column storing blob images. The application attempts to grab a subset of the images and runs some processing algorithms on them. The problem I'm running into is that, due to the rather large dataset that I have, the dataset that my query is returning is too large to store in memory. For the time being, I have changed the query to not return the images. While iterating over the resultset, I run another select which grabs the individual image that relates to the current record. This works, but the tens of thousands of extra queries have resulted in a performance decrease that is unacceptable. My next idea is to limit the original query to 10,000 results or so, and then keep querying over spans of 10,000 rows. This seems like the middle of the road compromise between the two approaches. I feel that there is probably a better solution that I am not aware of. Is there another way to only have portions of a gigantic resultset in memory at a time? Cheers, Dave McClelland

  • We have multiple app servers running against a single database. How do I ensure that each row in a q

    - by Dave
    We have about 7 app servers running .NET windows services that ping a single sql server 2005 queue table and fetch a fixed amount of records to process at fixed intervals. The amount of records to process and the amount of time between fetches are both configurable and are initially set to 100 and 30 seconds initially. Currently, my queue table has an int status column which can be either "Ready, Processing, Complete, Error". The proc that fetches the records has a sql transaction with the following code inside the transaction: 1) Fetch x number of records into temp table where the status is "Ready". The select uses a holdlock hint 2) Update the status on those records in the Queue table to "Processing" The .NET services do some processing that may take seconds or even minutes per record. Another proc is called per record that simply updates the status to "Complete". The update proc has no transaction as I'm leaning on the implicit transaction as part of the update clause here. I don't know the traffic exceptions for this but figure it will be under 10k records per day. Is this the best way to handle this scenario? If so, are there any details that I've left out, such as a hint here or there? Thanks! Dave

  • SharePoint 2010 Hosting :: How to Customize SharePoint 2010 Global Navigation

    - by mbridge
    Requirements - SharePoint Foundation or SharePoint Server 2010 site - SharePoint Designer 2010 Steps 1. The first step in my process was to download from codeplex a starter masterpage http://startermasterpages.codeplex.com/ . 2. Once you downloaded the starter master page, open up your SharePoint site in SharePoint Designer 2010 and on the left in the “Site Objects “ area click on the folder “All Files” and drill down to catalogs >> masterpages . Once you are in the Masterpage folder copy and paste the _starter.master into this folder. 3. The first step in the customization process is to create your custom style sheet. To create your custom style sheet, click on the “all Files” folder and click on “Style Library.” Right click in the style library section and choose Style sheet. Once the style sheet is created, rename it style.css. Now open the style sheet you created in SharePoint Designer. 4. In this next step you will copy and paste the SharePoint core styles for the global navigation into your custom style sheet. Copy and paste the css below into the style sheet and save file .s4-tn{ padding:0px; margin:0px; } .s4-tn ul.static{ white-space:nowrap; } .s4-tn li.static > .menu-item{ /* [ReplaceColor(themeColor:"Dark2")] */ color:#3b4f65; white-space:nowrap; border:1px solid transparent; padding:4px 10px; display:inline-block; height:15px; vertical-align:middle; } .s4-tn ul.dynamic{ /* [ReplaceColor(themeColor:"Light2")] */ background-color:white; /* [ReplaceColor(themeColor:"Dark2-Lighter")] */ border:1px solid #D9D9D9; } .s4-tn li.dynamic > .menu-item{ display:block; padding:3px 10px; white-space:nowrap; font-weight:normal; } .s4-tn li.dynamic > a:hover{ font-weight:normal; /* [ReplaceColor(themeColor:"Light2-Lighter")] */ background-color:#D9D9D9; } .s4-tn li.static > a:hover { /* [ReplaceColor(themeColor:"Accent1")] */ color:#44aff6; text-decoration:underline; } 5. Once you created the style sheet, go back to the masterpage folder and open the _starter.master file and in the Customization category click edit file. 6. Next, when the edit file opens make sure you view it in split view. Now you are going to search for the reference to our custom masterpage in the code. Make sure you are scrolled to the top in the code section and press “ctrl f” on the key board. This will pop up the find and replace tool. In the” find what field”, copy and paste and then click find next. 7. Now, in the code replace You have now referenced your custom style sheet in your masterpage. 8. The next step is to locate your Global Navigation control, make sure you are scrolled to the top in the code section and press “ctrl f” on the key board. This will pop up the find and replace tool. In the” find what field”, copy and paste ID="TopNavigationMenuV4” and then click find next. Once you find ID="TopNavigationMenuV4” , you should see the following block of code which is the global navigation control: ID="TopNavigationMenuV4" Runat="server" EnableViewState="false" DataSourceID="topSiteMap" AccessKey="" UseSimpleRendering="true" UseSeparateCss="false" Orientation="Horizontal" StaticDisplayLevels="1" MaximumDynamicDisplayLevels="1" SkipLinkText="" CssClass="s4-tn" 9. In the global navigation code above you should see CssClass="s4-tn" . As an additional step you can replace "s4-tn" your own custom name like CssClass="MyNav" . If you can the name of the CSS class make sure you update your custom style sheet with the new name, example below: .MyNav{ padding:0px; margin:0px; } .MyNav ul.static{ white-space:nowrap; } 10. At this point you are ready to brand your global navigation. The next step is to modify your style.css with your customizations to the default SharePoint styles. Have fun styling and make sure you save your work often. Hope it helps!!
