  • RAID striping on a desktop machine

    - by Blazemore
    I currently have a 120Gib SSD which is pretty fast for things like game loading times and video editing. However, I was wondering about getting another identical drive and hooking it up with a striping RAID array in hardware (I boot multiple operating systems). This would have the dual benefits of providing a larger logical drive, while also providing greater performance. However, I have a few questions: What kind of performance increase can I expect to see with a pair of good quality SSDs? How expensive is a quality desktop RAID controller? Will the controller present the OS with a single logical drive? Does this mean I can still partition it and multi-boot? Basically, can I treat the RAID controller as "a hard drive" at the OS level?

  • Which topics do I need to research to enable me to complete my self-assigned "Learning Project"?

    - by Anonymous -
    I want to continue learning C#. I've read parts of a few books recommended on here and the language is feeling more familiar by the day. I'd like to tackle a mid-sized personal project to take my expertise to the next level. What I'd like to do, is create an application that 'manages expenses', that runs on multiple machines on a LAN. So for example, say we have person1 and person2 on seperate machines running the application, when person1 enters an expense, it will appear on person2's (pretty UI) view of the expenses database and vice versa. What topics do I need to research to make this possible for me? I plan on learning WPF for the UI (though the steep learning curve (or so I'm told) has me a little anxious about that at this stage. With regards to the database, which database would you recommend I use? I don't want a 'server' for the database to run on, so do I need to use an embedded database that each client machine runs a copy of that updates to each other (upon startup/entering of expense on any machine etc)? What topics under networking should I be looking at? I haven't studied networking before in any language, so do I need to learn about sockets or?

  • ESXi onboard SATA passthrough [on hold]

    - by lodge93
    I am running ESXi 5.5 on a home system. When I attempt to pass one of the onboard SATA controllers (Intel ICH10R) to a VM, it is successful. However, the controller never appears in the VM. What else am I missing that would cause a VM to not recognize the controller? Additional Info: The controller is set to AHCI mode in the BIOS Prior to setting up the controller for passthrough, ESXi did recognize the controller and the drives I have tried with multiple VMs, none of which recognized the controller or the attached drives I have two onboard SATA controllers, on controller for ESXi and one for passthrough The final ideal state is that I could passthrough the controller to a FreeNAS VM

  • Open file without specifying exact location

    - by person
    Say I have a file in some obscure directory that I want to open and edit. I don't want to do something like this... vim ~/foo/bar/blah/doh/ugh.txt I'd rather be able to say find this file and open it. I know there are commands like locate and find to find a file or directory, but I'm not sure whether these can (or even should) be utilized in what I'm trying to do. Basically, what is the simplest way to open a file with a program w/o specifying its exact location? (In cases where there isn't another file with the same name in the entire system, and cases where there are multiple).

  • SharePoint (2010) - Can't delete Service Application

    - by Chris W
    The search service application in our farm went bonkers complaining that it couldn't connect to itself. After multiple people fiddling to try and fix it we've ended up with two search application. The new one, which is working perfectly, and the original one which is very unhappy. I've tried deleting the original Search App in Central Admin but it just won't go - it sits on the screen saying "Processing" but it never completes regardless of how long it is left. There's lot's happening in the logs but I can't really decipher exactly why this isn't working. Things are working fine within the farm but I'd ideally like to clean up this old application if possible. Are there any other options like deleting it with stsadm? I've had a dig but can't seem to find the commands to enumerate the service applications and then delete the correct one.

  • I do not understand -printf script

    - by jerzdevs
    I have taken over the responsibility of RHLE5 scripting and I've not had any training in this platform or BASH scripting. There's a script that has multiple pieces to it and I will ask only about the second piece but also show you the first, I think it will help with my question below. The first part of the script shows the output of users on a particular server: cut -d : -f 1 /etc/passwd The output will look something like: root bin joe rob other... The second script requires me to fill in each of the accounts listed from the above script and run. From what I can gather, and from my search on the man pages and other web searches, it goes out and finds the group owner of a file or directory and obviously sorts and picks out just unique records but not really sure - so that's my question, what does the below script really do? (The funny thing is, is that if I plug in each name from the output above, I'll sometimes receive a "cannot find username blah, blah, blah" message.) find username -printf %G | sort | uniq

  • SQL Server database constantly restarting

    - by Michael Itzoe
    We have SQL Server 2008 Express installed on a Windows 2003 server. Looking at the event log, one of the databases appears to be restarting anywhere from every couple seconds to every 15 to 30 minutes. This server hosts about half a dozen databases; the problem is with only one. This database is also the onle one comprised of multiple schemas (not just dbo). There are thousands of events going back several months. There doesn't seem to be any affect on the website using the database, nor does any data appear to be corrupted or compromised. I'm not a DBA, so I don't even know where to look for causes to this. Any suggestions?

  • Replication with AK8

    - by Steve Tunstall
    Hello folks, This came up today and I want to make sure it's clear. Remember the "deferred update" I spoke about in my "Upgrade to AK8" entry just a bit ago? It's important to understand that this deferred update changes the way replication works. It is necessary that systems with the deferred update applied only replicate with other systems that have also had this deferred update applied. So if you apply it, your system can NOT replicate with ANY other system that has NOT had it applied, even if that other system is running AK8!!! Got it??? Remember, we do have a new version of the 2011 code for the older systems that do not want to upgrade to AK8. This 2011.1.8 code ALSO HAS this same deferred update in it. So, if you upgrade your system to AK8, and then apply the deferred update, and you have another system running either 2011.1.8 or AK8, you can replicate with them again once they apply the deferred update for multiple initiator groups. Yes, even if you're not using LUNs. Here is what it looks like if you try. It will fail.

  • SSH - SFTP/SCP only + additional command running in background

    - by Chris
    there are many solutions described to get ur SSH-connection forced to only run SFTP by modifying the sshd_config by adding a new group match and give that new group a Forcecommand internal-sftp Well that works great but i would love to have a little more feature. My servers automatically ban IP's which try to connect often in a short time. So when you use any SFTP-Client, which opens multiple connections to work faster it can get banned instandly by the server for a long time. The servers have a script to whitelist users by administrator. I've modified this script to whitelist the user, which runs the script. All i need to do is now get the server to execute that script, when somebody logins. On SSH it's no problem, just put it in .bashrc or something like, but the Forcecommand don't runs these scripts on login. Is there any way to run such a shellscript before or at the same time as the Forcecommand get fired?

  • Disabling the right-click sub menu using JQuery

    - by nikolaosk
    Recently I needed to disable the right-click contextual menu in an HTML page for a very simple HTML application I was creating for a friend.This is going to be a short post where I will demonstrate how to disable the right-click contextual menu.I will use the very popular JQuery Library. Please download the library (minified version) from http://jquery.com/downloadPlease find here all my posts regarding JQuery.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here. I am going to create a very simple HTML 5 page with some text and an image. The HTML markup for the page follows. <!DOCTYPE html><html lang="en">  <head>    <title>HTML 5, CSS3 and JQuery</title>        <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">     <script type="text/javascript" src="jquery-1.8.2.min.js">        </script><script type="text/javascript"> (function ($) { $(document).bind('contextmenu', function () { return false;}); })(jQuery); </script>       </head>  <body>      <div id="header">      <h1>Learn cutting edge technologies</h1>      <h2>HTML 5, JQuery, CSS3</h2>    </div>      <figure>  <img src="html5.png" alt="HTML 5"></figure>        <div id="main">          <h2>HTML 5</h2>                        <article>          <p>            HTML5 is the latest version of HTML and XHTML.

  • Video streaming over multi display units

    - by ramdaz
    We have to share video across around 4/8 terminals at a public facility where we need to display live video from within the facility, as well as display messages(advertisements), and also play videos(not live) which need to be controlled centrally from another location. We can do central location handling over Internet, over ssh. What we want to do is connect cameras to a computer, and use the computer to display over multiple display units. We need to do live titling if possible. Once the live local telecast which usually takes about an hour or two a day, we would like to play other videos locally off the PC server. Preferably everything should run off Linux, since budgets are very constrained.... Addendum -- Its not over WAN, it's over a local area. I prefer not using LAN, we would rather use co-axial cable if possible. The reason is if it's LAN, I need some kind of an Networking device, at least a thin client

  • Reliance on Outlook (been a looong time, I know)

    - by AndyScott
    Do you feel that your development group too reliant on Outlook? Have you reached a point that you have to search your email for pertinent information when asked? What are you using? I realized things had gotten out of hand a couple weeks ago over a weekend. I was at my in-laws house (in the country, no PC/laptop, no internet connection; and I get an email on my phone that I needed to reply to, but I couldn't send without deleting items from my inbox/sent items/etc. Now mind you, I have rules set up to move stuff into folders, and files more than a month old are automatically moved to the PST; but generally don't manually move items to a PST until I have had a chance to 'work' the item. Please don't bother mocking my process, it's just the way I work. That being said, it was a frustrating process of 'I need all this information, what can I afford to lose'. I work on an International project (think lots of customers), and conversations in 9 or 10 different directions about 10-20 different things are not abnormal for a given day. I have found myself looking data up in Outlook because that's where it is. I think that I have reached the point now, where I don't feel that Outlook is up to the task of organizing the data that it contains.   When you have that many emails (200 or so a day), information seems to get lost at times, and I find that Outlook's search capabilities are lacking. Additionally, I find that any sort of organizational 'system' of sorting emails that can cover multiple topics is a lost cause. But at the same time, the old process of taking the information that I got from emails and moving it into another 'notes' type of program has proved to be too time consuming. Anyone out there have some better type of system? (Comments about the capacity of my brain, and it's ability to recall information not needed.)

  • What is the best ways to duplicate DVDs in bulk?

    - by Axxmasterr
    I have some instructional videos I am getting ready to release on DVD and I want to know what is the quickest and most cost effective way to produce these in bulk? I am open to both customized PC based software/hardware solutions as well as dedicated hardware appliances which perform the same function. All options considered seriously. I don't have a problem building a system for this purpose. If I build something I would prefer it have the ability to make multiple copies at once. I figure I will need to make about 300 copies initially.

  • HTTPS load balancing based on some component of the URL

    - by user38118
    We have an existing application that we wish to split across multiple servers (for example: 1000 users total, 100 users split across 10 servers). Ideally, we'd like to be able relay the HTTPS requests to a particular server based on some component of the URL. For example: Users 1 through 100 go to http://server1.domain.com/ Users 2 through 200 go to http://server2.domain.com/ etc. etc. etc. Where the incoming requests look like this: https://secure.domain.com/user/{integer user # goes here}/path/to/file Does anyone know of an easy way to do this? Pound looks promising... but it doesn't look like it supports routing based on URL like this. Even better would be if it didn't need to be hard-coded- The load balancer could make a separate HTTP request to another server to ask "Hey, what server should I relay to for a request to URL {the URL that was requested goes here}?" and relay to the hostname returned in the HTTP response.

  • How do I block a single css file from being loaded with firefox or chrome?

    - by Tim Santeford
    I want to be able to block one css file from loading on my system. The site has multiple sheets that I do want to load but it has one hideous theme.css file that I just have to get rid of. I would prefer to use Chrome but FF is ok too. A system wide ban on the file would be ideal. I want to specify a single url that the computer becomes incapable of fetching it. I will then use stylish to create my own replacement. BTW its a SharePoint theme and it has way too many rules to have to override. Thanks

  • Explaining svn / apache permissions error? (I know "how" but not "why")

    - by Neil
    I have the following error occurring on occasion when trying to do an svn switch (have it set up to do via a web request): svn: Can't open file '/root/.subversion/servers': Permission denied This happens after an apache httpd.conf change and corresponding restart. How to fix this? I can get it to fix by doing an apache restart - BUT, it often takes multiple tries. Curious if anybody can explain this. Why did this error go away on my 8th apache restart, but not on the prior ones (with no edits to the conf file)? Basically, I kind of have a "how" in terms of solving this, but I don't have a "why" . . . Thanks!

  • Skype audio always goes 'robotic' for the same user

    - by John
    Someone I talk to on Skype a lot has a very persistent issue, where after a few minutes their voice goes very 'robotic'... still understandable but annoying. We can restart the call and it's fine, but fairly consistently after a few minutes it returns. He experiences this with other people too, not just me - I don't have anyone report problems with my audio quality. This is not an ISP issue - he gets the same problem on multiple PCs in different countries, in fact he's even recently moved to a different continent and got a new internet connection... same problem. It seems somehow to be a problem with his Skype account, which is really quite odd. It's been going on for months of not longer.

  • Minimal Lync 2013 Setup

    - by vkapadia
    I would like to install a Lync 2013 server at home. What would be the minimum requirements for it? I've seen the requirements and they seem pretty hefty, just want to know what I need for a basic set up. This will be for up to 5 users. I would like users to be able to connect from outside the network as well. From what I've been able to find, it looks like I'll need 3 servers. A domain controller, a lync front end server, and an edge server (for external connectivity, and it will need 2 network cards). Is that really all necessary? And how would they need to be connected (I've never connected a machine with multiple network cards)? Do they all have to be separate machines, or can I use VMs?

  • SEO consideration for duplicate sites

    - by Malk
    I am building a brochure-ware website for a company that sells products all across the world. They need the site to ask the user what region they are in before using the site; there are 5 regions. This is because there are different products offered to different regions and each region may or may not want to customize their own content. However, at launch and likely forever, most of the pages will be the exact same minus what is listed in the footer and in the product selection menu. My question is how should I structure the sitemap for this site for best SEO? Should I be concerned with duplicate content penalties and/or cannibalizing the site's presence on the SERP? Some considerations: The client wants to be able to print links directly to regional specific content bypassing any prompt for the user to select a region (to ensure they land on the target page). The client cannot have a 'default' region so the user must have a region specified "Clean" urls are important, but there is wiggle room The client does not want each region to have its own domain There will be a link on the page to allow users to specify a different region The client is not concerned with localization ...at this time Some products are available in multiple regions A quick list of options I am considering: www.site.com/region/page region.site.com/page www.site.com/page?region (no cookie, pages require the parameter. If visited without; the user must select a region) www.site.com/page (using cookie and a splash screen if needed; could pass parameter in to set the region for direct linking) Thanks in advance for your advice.

  • Uptime concerns in case of AWS outage

    - by Aditya Patawari
    I am running an Elastic Load Balancer backup by 2 instances in different Availability Zones in US East. I am using Multi-AZ RDS as well. Ideally this should ensure that if one AZ goes down, it should not effect the app because everything is spread across multiple AZs. But the recent AWS outage took the app down for a long time. I am not sure how this can happen. It would be great if someone can point out what went wrong. Major question here I have is how can I avoid this in future? I can setup app servers across different regions or even providers and use DNS for load balancing but what do I do with MySQL? Read Replicas will introduce some lag which I would want to avoid.

  • Git Repo to mantain the app configurations in several servers

    - by user62904
    Hi! I need to versioning in a GIT repository, configurations of a particular platform, spread across multiple servers. Take into account that in each of these servers there are completely different configurations, while the application is the same. What is the best way to do this? Create a branch for each server repository.git:conf -- [branch Server 1] repository.git:conf -- [branch Server 2] repository.git:conf -- [branch Server N] Note: This method seems to me, that is difficult to maintain because each change in the server configurations, I need to create subbranches which becomes confusing. Create a single repo with a different directory for each server repository.git:conf/Server 1 repository.git:conf/Server 2 repository.git:conf/Server N Note: This is easy to mantain Create a repo for each server repository_1.git:conf repository_2.git:conf repository_N.git:conf Note: This method requires me to create a branch for each new server. There are other methods, what are the best practices in this case? Should I use the one that I feel most comfortable? Tks, Gulden PT
