• Upgrade no raid server to raid

  - by AZee

  I have just learned that our PDC has a single drive with 2 partitions. I also know that this drive has bad blocks as recorded in the event log. What I would like to do is to convert this to a RAID solution with a nice balance between economy and performance. I will admit that I have only configured servers with RAID from scratch, and have no experience upgrading an existing system into a RAID system. In fact, I'm not sure it is even possible. Since this is the PDC for 350+ workstations downtime is important. I'd like to hear from other System Administators how they would tackle this and their recommendations for all devices. At this time it seems to me that I can replace the existing drive and then restore from backup or install a controller, drives, configure the RAID an basically start from scratch. Thank you for taking your time. ~AZee

• How SSD's drives reduce their latency?

  - by tigrou

  First time i read some information about SSD's, i was surprised to learn they internally use NAND flash chips. This kind of memory is generally slow (low bandwidth) and have high latency while SSD's are just the opposite. But here is how it works : SSD drives increase their bandwidth by using several NAND flash chips in parallel. In other words, they do some data striping (aka RAID0) across several chips (done by the controller). What i don't understand is how SSD's drives managed to reduce latency? (or at least lot better than what a single NAND chip without any controller can do)

• How do you override the warning "filename is not commonly downloaded" for a specific file?

  - by Oliver Salzburg

  There is a specific file on a customers server which I require to connect to one of their services. The contents of the file are confidential and the file is not intended for the public. Thus, the file is not "commonly downloaded", and every time I need to download it, I get this warning: I have to download that files sometimes multiple times a day (the contents of the file change periodically) and, every time, I have to click through this little annoyance. The Phishing and malware detection page only explains how to disable the feature completely, which is not what I want at all. Can I disable this feature for a single given URL?

• Display CPU usage separately (without root privileges)

  - by synaptik

  I need to display the CPU usage for each processing core on a single shared-memory 12-core (SMP) machine. I don't have access to install htop, else I would simply use that. I don't need fancy graphs or meters, though they would be nice. For example, simply displaying: X X X X X X X X X X X X where each X is the percentage utilization of 1 of the 12 processing cores on my machine. FYI: I know I can simply look at the utilization in "top" and divide that number by the number of cores on my machine, but I prefer a solution that shows each core separately.

• Ubuntu 11.10 loads from live usb fine, but boots to black screen from harddrive. Why?

  - by Estel

  A few days ago I had a hard drive failure, which was running Windows XP (32-bit) just fine. The second hard drive in my computer held a few unimportant files, so I formatted it in the Ubuntu setup and installed 11.10 without a hitch. I had been using it for about a week, but decided to install Windows 7 (64-bit) in order to utilize Networking with my home server (running Windows Server 2000). My system is 64-bit based, and thus I had no problems installing other than a basic RAM error that required me to remove my RAM down to a single stick. I played with the settings in Windows 7 for around an hour before I shut down. After reinstalling the RAM, Windows 7 would not boot. In this, I then assumed that something about my system was rejecting Win7 and I reinstalled Ubuntu. However, now Ubuntu (11.10) boots into black screen, and I've already attempted activating the grub menu with the shift key, and following steps listed here: https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen but nothing seems to work. I've reinstalled twice now, with the same result each time. Now, the very odd part about this whole scenario is that the USB I installed from has no problems booting as a live USB. This puzzles me greatly, because the hard drive boots straight to black screen and the live USB loads normally. At this point, my only theory is that the boot sector of the hard disk was somehow corrupted with Win7, and that Ubuntu was unable to completely write through. I used Darik's Boot n Nuke to wipe the drive, but was met with an error, this also puzzles me because the hard disk has no promblems reading or writing. Any suggestions/comments are appreciated. If you have a theory, I will be more than happy to oblige. Additional information: Intel Core2 Duo e6400 2.13GHz nVidia GeForce 7-series (7900 GS) 4 GB DDR2 333MHz (2x 2GB) Dell XPS 410 BIOS Revision 2.5.3

• Is there a chroot build script somewhere?

  - by Nils

  I am about to develop a little script to gather information for a chroot-jail. In my case this looks (at the first glance) pretty simple: The application has a clean rpm-install and did install almost all files into a sub-directory of /opt. My idea is: Do a find of all binaries Check their library-dependencies Record the results into a list Do a rsync of that list into the chroot-target-directory before startup of the application Now I wonder - ist there any script around that already does such a job (perl/bash/python)? So far I found only specialized solutions for single applications (like sftp-chroot). Update I see three close-votes for the reason "off topic". This is a question that arose because I have to install that ancient piece of software on a server at work. So if you still feel this is off-topic - leave a comment...

• Setting up Dependencies for Nagios

  - by hfranco

  I'm trying to setup dependencies for a router and several servers. What I want to do is setup the router as the Master Host so if the router fails all other services on the servers won't alert. Unfortunately this is easier said than done. Is there an easy way to setup service dependencies for all services on a server for a Master Host (or my router)? Nagios has some documentation but it will be extremely time consuming to add a single service dependency definition for every service. http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#servicedependency

• In an online questionnaire, what is a best way to design a database for keeping track of users all attempts?

  - by user1990525

  We have a web app where users can take online exams. Exam admin will create a questionnaire. A questionnaire can have many Questions. Each question is a multiple choice question (MCQ). Lets say an admin creates a questionnaire with 10 questions. Users attempt those questions. Now, unlike real exams users can attempt single questionnaire multiple times. And we have to keep track of his all attempts. e.g. User_id Questionnaire_id question_id answer attempt_date attempt_no 1 1 1 a 1 June 2013 1 1 1 2 b 1 June 2013 1 1 1 1 c 2 June 2013 2 1 1 2 d 2 June 2013 2 Now it can also happen that after user has attempted same questionnare twice, admin can delete a question from same questionnaire, but users attempt history should still have reference to that so that user can see his that question in his attempt history in spite of admin deleting that question. If user now attempts this changed questionnaire he should see only 1 question. User_id Questionnaire_id question_id answer attempt_date attempt_no 1 1 1 a 3 June 2013 3 Also, after this user modified some part of question, users attempt history should show question before modification while any new attempt should show modified question. How do we manage this at the database level? My first gut feeling was that, For deletes, do not do physical delete, just make a question inactive so that history can still keep track of users attempt. For modifications, create versions for questions and each new attempt refres to latest version of each question and history keeping reference to version of question at attempt time.

• Robust way to keep records of software releases?

  - by japreiss

  We release a number of small plug-ins that go along with our software. Each plug-in allows our software to talk to a single manufactuer's hardware. I would like to devise a system for keeping track of plug-in releases. Example info that should be stored: Hardware manufacturer name 32-bit? 64-bit? both? What modes of operation does the hardware support? What versions of the manufacturer's driver have been tested with the plugin? Desirable properties of the system: Able to synchronize with version control software Stores data in human-readable text file (also good for differ tool) Free visual, spreadsheet-like editor available Able to do simple analysis like "What is the oldest plug-in?" I've got to imagine that someone else has tackled this problem already. Right now my best guess is XML/JSON with a visual editor, but I have been disappointed in the editors I've tried so far. I'd like to get input from some more experienced developers. Thanks!

• Setting up Mac VPN on simple network with separate IPs

  - by Dave

  Hi there, We have a pretty simple network configuration. A typical ASDL line with two extra IP addresses. We have a basic home network router Dlink DIR-655. We have two Mac OS X Snow Leopard Servers that we want to setup VPN on. The problem is that we can't change the ports which VPN works under ie. we can only setup port forwarding for UDP 500,1701,4500 to a single server. I'm wondering how we can cost effectively re-work our network so that we can take advantage of the separate IP addresses and have both VPNs working with the same router. Is that possible with our current hardware setup or do we need something more powerful? We're also toying with Mobile Access and wondering if that might be easier to setup. Expert help is greatly appreciated.

• Can GNU sed (for Windows) handle Unicode? If so, is it a code-page/locale issue, or a switch?

  - by Peter.O

  I've been using GNU SED on and off for a couple of years now. It spins me out a bit sometimes, but it does a good job... for single-byte char sets! I now and then notice references to GNU SED being Unicode-aware, but the closest I've seen of this is its "binary" mode.. and binary is not Unicode. Can GSED process a Unicode text file at CodePoint resolution, including and especially \r\n (Windows)... and if it can, does it expect UTF-8, UTF-16, or what? and how does SED detect the encoding?

• Is there a schematic overview of Ubuntu's architecture?

  - by joebuntu

  Hi there, as enthusiastic, advanced Linux learner, I'd love to get an overview about Linux' architecure/structure in general. You know, like "the big picture". I'm thinking of a large schematic graphic showing what is what, who is who, what system (e.g. X) comprises which subsystems (GDM/Gnome/Compiz) on the way from a to z, from boot to interactive desktop, including the most important background services (auth, network, cron, ...). Maybe a bit like this: http://www.flickr.com/photos/pgc/140859386/ but way more detailed. There's bootchart, which produces very comprehensive charts, but they again are too detailed and difficult to get the "big picture" from. Is there such a thing? Possibly not for the whole System, but maybe for single subsystems? I had trouble searching for this, because using search terms like "scheme" or "architecture" pointed to the wrong direction (a tool called "scheme" or CAD software for linux). I appreciate any links. If there's interest in those schematic overviews and links, maybe someone could turn this post into a wiki post? Cheers, joebuntu

• Powershell enters foreach loop with null object

  - by SteB

  I'm listing all backups in a given directory: $backups = Get-ChildItem -Path $zipFilepath | Where-Object {($_.lastwritetime -lt (Get-Date).addDays(-7)) -and (-not $_.PSIsContainer) -and ($_.Name -like "backup*")} If I set it to deliberately return no files (.addDays(-600) then the following prints "Empty" (as expected): if (!$backups) { "Empty" } If I try to list the names with an empty $backups variable: foreach ($file in $backups) { $file.FullName; } I get nothing (as expected), if I change this to: "test"+ $file.FullName; then I get a single "test" under the "Empty". How is this possible if $backups is empty?

• Abbreviations override in comments and quoted text

  - by dotancohen

  I have the following handy abbreviation in VIM: iab for for<Space>(<Space>{{<Esc>kA<Left><Left><Left><Left><C-R>=Eatchar('\s')<CR> This nicely replaces for with the following text: for ( ) { } However, I would like this abbreviation to work only in code, not in comments or in single- or double- quoted strings. How might this constraint be accomplished? Note that I usually code in PHP, but often enough I find myself in other C-style languages (C, Java, occasional C#, etc.). Preventing the abbreviation from working in Python would be a nice bonus though I don't mind manually turning it off in Python if that is not an option. Thanks!

• Lenovo ThinkServer TS130 1105 - does 32/64 depend on RAM?

  - by Ecnerwal

  Just got in a Lenovo ThinkServer TS130 1105 (Xeon E3-1225V1) and a (new, sealed, holographed, looks legit) copy of Windows Server 2008 32/64 (standard) to run on it for a pretty lightweight job (currently handled, adequately, by a terrifyingly old Optima P4 running Windows 2000 server - really lightweight, but long-past-due for replacement, without any particular need or excuse for server 2012...) The 64 bit disc sits there and does nothing. The 32 bit disc boots. I haven't spotted any mention of this in the TS130 Manual (I have now combed it, and find no mention of a need to populate in pairs - a preferred order to populate in, yes, but no mention of pairs being required) but I begin to wonder if it's due to the fact that the 4GB RAM suppled with it was a single DIMM, rather than a pair. Better for upgrading, but perhaps requiring an upgrade (or sidegrade) right away to install the x64 version?? Anyone know? I tried the 64-bit DVD on a desktop with an AMD Athlon II X4 635 processor which normally runs Windows7 in 64 bit, and it booted up just fine.

• Hyper-V Server 2008 Configuration

  - by Eternal21

  I need to set-up Lync on a Server 2008 machine. The problem is that Lync cannot be set up on a Domain Controller. That means I need to have one Server 2008 that's a domain controller and another that's Server 2008 running Lync. I figured the best way would be hosting it on a single machine, using virtual machines. I installed Server 2008, but now my question is this. Do I add two virtual machines (Domain Controller and Lync), or do I only add one virtual machine for Lync, and the 'parent' Server 2008 can act as a domain controller?

• Filling cells with sequential numbers in an Excel (2003) macro

  - by Fred Hamilton

  I need to fill an excel column with a sequential series, in this case from -500 to 1000. I've got a macro to do it, but it takes a lot of lines for something that seems like it should be a single function [something like FillRange(A2:A1502, -500, 1000, 1)]. But if that function exists, I can't find it. Is the following as simple and elegant as it gets? 'Draw X axis scale Cells(1, 1).Value = "mV" Cells(2, 1).Value = -500 Cells(3, 1).Value = -499 Cells(4, 1).Value = -498 Dim selection1 As Range, selection2 As Range Set selection1 = Sheet1.Range("A2:A4") Set selection2 = Sheet1.Range("A2:A1502") selection1.AutoFill Destination:=selection2

• Enable/disable wireless interface in a bat file

  - by Herms

  Is there a way to enable/disable a wireless network interface via the command line (so I can put it in a bat file)? When I'm in the office I use a wired connection, but Windows still occasionally bugs me about my wireless connection not being connected (even though I turned off the option for notifying me when there's no connectivity). I'm guessing the only way to stop it from bugging me is to disable the interface, but I'd rather not have to go into the network settings every time I need to do so. I'd like to set up a bat file or a shortcut that I can use to enable/disable the wireless (preferably a single one that toggles the current state), and then just set up a keyboard shortcut for that. I just have no idea how to do so from the command line.

• More efficient in range checking

  - by Mob

  I am going to use a specific example in my question, but overall it is pretty general. I use java and libgdx. I have a ship that moves through space. In space there is debris that the ship can tractor beam in and and harvest. Debris is stored in a list, and the object contains it own x and y values. So currently there is no way to to find the debris's location without first looking at the debris object. Now at any given time there can be a huge (1000+) amount of debris in space, and I figure that calculating the distance between the ship and every single piece of debris and comparing it to maximum tractor beam length is rather inefficient. I have thought of dividing space into sectors, and have each sector contain a list of every object in it. This way I could only check nearby sectors. However this essentially doubles memory for the list. (I would reference the same object so it wouldn't double overall. I am not CS major, but I doubt this would be hugely significant.) This also means anytime an object moves it has to calculate which sector it is in, again not a huge problem. I also don't know if I can use some sort of 2D MAP that uses x and y values as keys. But since I am using float locations this sounds more trouble than its worth. I am kind of new to programming games, and I imagined there would be some eloquent solution to this issue.

• Which iPhone ad API has produced the highest revenue for you?

  - by Kyle Humfeld

  This isn't a technical question, but more of a request for advice and empirical/anecdotal data. I'm nearly done writing a free app for iPhone, and I'm at the stage where I'm going to put ads into the app. I've had mixed success in the past with iAd (their fill rates have been atrocious recently, and their payouts have cut by about 75% over the past 4 months or so), and would like to know how much ad revenue you, the community, has seen from the various ad APIs you've used for your iPhone apps. This isn't a request for opinion, i.e. which is 'better', only what kinds of numbers you're seeing. I don't need absolute figures, but 'iAd pays x% higher than AdMob, and y% lower than AdSense' would be extremely helpful to me as I make my decision as to which ad API to integrate into my App. Also, have you had any experience or success with integrating multiple ad APIs into the same app? That's something I'm considering doing in my current iAd-filled apps (particularly my iPad app, which has yet to receive a single impression after nearly 60,000 requests)... something like: 1) Request-from-iAd 2) if that fails, request-from-adSense 3) if that fails, request-from-adMob 4) if that fails, ... etc.

• How do I know if my Xeon Processor supports hardware virtualisation?

  - by gshankar

  I've been scouring the net (mainly the wikipaedia lists and intel's site. I even pulled out the datasheet for my processor) but I can't seem to answer this question. Does my Xeon support hardware virtualisation? The processor in question is a: "Nocona" (standard-voltage, 90 nm) 2800MHz. Other details can be found here: http://en.wikipedia.org/wiki/List_of_Intel_Xeon_microprocessors#.22Nocona.22_.28standard-voltage.2C_90_nm.29 I'm pretty sure the answer is no as it's a pretty old server but I can't find a single place which has a definitive yes/no answer so I'm still looking...

• When adding second processor to SQL Server, will it automatically balance the load?

  - by ddavis

  We have a SQL Server 2008 R2 (10.5) on a dedicated box with a single 2.4Ghz processor, which regularly runs at 70-80% CPU. We are going to be adding a significant number of users to the application and therefore want to add a second processor to the box (scale up). Will SQL Server automatically use the second processor to balance threads, or is there additional configuration that will need to be done? In other words, will adding the second processor drop my CPU usage to 35-40% per CPU, automatically balancing the load? Based on what I read here, it seems that it will: http://msdn.microsoft.com/en-us/library/ms181007.aspx However, I've read elsewhere that CPU performance gains can be made by assigning database tables to different filegroups, but I'm not sure we want to get that complicated at this point.

• Change Keybindings (hardware to software)

  - by Daniel

  I ran a search for this, but the answers I saw were referring to something altogether different than what I'm asking for. So let me clarify: I'm not asking how to change key-combo shortcuts. I'm asking--how do you actually change what your computer thinks you did when you press a given key? An example of what I mean (and the reason I'm asking). I'm a Chrome user, and I use Windows alongside Ubuntu. I own a Lenovo Thinkpad T61p--it came with my scholarship package, and I would have shopped for a nice computer if I could have. The T61p has two buttons above the left and right arrow keys that relate to browser commands to go back and forth one page. This is extremely frustrating for me, as I use the arrow keys, and a single accidental keystroke will catch me going back a page, losing temporary data, and yelling at my stupid keyboard. At the same time, I'm the type of person who keeps way too many tabs open. Chrome doesn't let me refigure keyboard shortcuts, and the only way it allows you to switch between tabs are ctrl+tab and ctrl+shift+tab, and ctrl+page up/down. I was using Notepad++, and they had finally found the solution to both problems! The page back and forth keys functioned as tab back and forth keys. I went through quite some effort to learn how to change the keybindings in Windows. The page back and page forward keys are now the page up and page down keys, respectively, and if I hit control, they let me switch tabs easily, and rather pleasantly. And if I hit the keys by accident, no harm, no foul. Alas, I'm in Ubuntu now, and I need to go through the process again. And while I couldn't just find the answer online, like I did for Windows, I know Ubuntu has nice, supportive communities like this one, where, hopefully, somebody can tell me how to do either what I did in Windows, or directly make it so that my computer changes tabs when I hit those buttons (removing the ctrl button from the tab-changing command).

• Is there a media player that allows me to group together radio streams which are just mirrors of the

  - by rakete

  I find it really annoying that for some radio stations, which have two or more servers to cope with the network load, there is not one single entry in amaroks playlist but two or more entries. This makes it hard to pick the radio station from the list I like to listen to because all the entries are always shown with the last played track as name, and even if I only have a few radio stations in my list there will eventually be many different entries. And, if I use the keyboard shortcuts to navigate the playlist I always have to remember that radio station X has for example four entries in the playlist, so I have to press the shortcut for switching tracks four times to actually switch the to the next station. Now, ideally I would like some solution for amarok, but if someone knows of another media player that does this or something I would appreciate that information as well.

• After installing Windows 8, boot hangs before BIOS setup

  - by Joe Purvis

  I have an Alienware M15x, 940MX processor, 16 GB RAM, 512GB M4 SSD, and I was running Win7 64bit. I backed up the disk and ran Win 8 setup. Setup appeared to go well through multiple reboots. After the last reboot, it simply stopped after POST at "Press F2 for bios setup". I have tried powering off, reducing RAM to one stick, removing MOS battery. Now, it gets to the screen with "Press F2 for setup" and "Press F12 for boot options". If I press F2, I get a single beep only. If I press F12, nothing. I cannot get into the BIOS to change boot options to boot from another disk and restore. I do have the latest BIOS. I am going to try replacing the CMOS battery, but I don't think that is likely to help. The computer has been fast and very reliable until now.
