• How do I diagnose the cause of a freeze after resuming in Windows XP (SP3)?

  - by Software Monkey

  I have just built a new computer from parts. Whenever I resume from any sleep mode (S1, S3 or S4) the computer freezes within about 60 seconds of the welcome screen appearing. I have updated the BIOS and all drivers to current from the motherboard manufacturer's site. I have reset BIOS settings to default, including disabling AMD Cool n Quiet. The windows event logs are not helpful at all. Other than immediately after resuming the system is stable as long as AMD CnQ is disabled. The system is: Mobo : MSI 790GX-G65 CPU : AMD Phenom II 965 BE at 3.6 GHz Memory : Corsair DDR3 1600, at 1333 MHz and 9-9-9-21 HDDs : 1 EIDE, 2 SATA in RAID-0 DVD : 1 Card Reader: 1 multi-card reader Keyboard is attached via PS2 and mouse is USB. Any thoughts or pointers would be most welcome. EDIT: It appears that the computer may not freeze if a program is left running which puts it under significant load. I left a stress test running which keeps all cores under 85% load, and my son put the computer to sleep - while this program is running it I have been able to resume from S3 successfully 4 times, compared against about 20 tests with the computer idle which have all frozen. So this may be related to being in an idle state when it resumes.

• Best way to troubleshoot intermittent network outages?

  - by Ben Scheirman

  We have a Comcast 50/10 line into our office. We keep seeing very short but sometimes frequent drops in our internet service. It's enough to kick you off of skype and stop any websites from loading, which is obviously affecting our productivity. We've tried 4 different routers, we've tried moving everyone off of wireless and onto wired via a switch and so far nothing has helped. Right now we're on a Cisco SB WRP400-G1 router. Attached to the router is a 16 port switch going to the ports in all of the offices. We've moved to OpenDNS in the case that it was the comcast DNS servers going down. Today we tried putting the modem, router, and switch on a UPS to make sure it wasn't power fluctuations that was causing it. Every time we call Comcast, by the time they are here the internet is working fine. I'd like to somehow prove that the problem is with Comcast, so if that means plugging in a machine directly into their router and collecting data all day, I'm up for that. I just want to hear ideas on what tools to run and how to collect this data. I could just continuously ping google.com all day long but I'm not sure how valuable that data would be. Thoughts?

• Completed downloads freeze Windows

  - by Ben Hooper

  The Issue Shortly after a file download via Google Chrome for Windows completes, the download will get stuck on "0 seconds left" and all other programs (except Google Chrome, for some reason, but browsing will not work) completely freezes into Windows' infamous "Not Responding" state, affecting Explorer particularly badly. Eventually, the programs will recover themselves but they will recover significantly faster if you cancel the file download, relative to how quickly you react. Performing the exact same operation immediately after cancelling the download usually works without issue. This issue occurs when with any file type (.ZIP, .MSI, .MSG, .PNG, .URL, etc) of any size from any source (Dropbox, SourceForge, Imgur, even tiny and locally-generated BLObs created by my own Chrome extension, etc) to any location.   Potential Causes As this issue is so inconsistent, I haven't been able to prove whether the issue is Chrome-specific or being caused by my system or my Chrome configuration but it's happening on both my work and home PCs. I originally suspected that this issue was being caused by security software scanning completed downloads for threats but I'm not as confident in that theory anymore as the issue persisted even after changing my security software from ESET NOD32 and Malwarebytes Anti-Malware Pro to ESET Endpoint to Microsoft Security Essentials.   System Information (of both PCs) Windows version: 7 Service Pack 1 64-bit Google Chrome version: 30.0.1599.101 (but has been happening for a long time)   Screenshots

• How to increase the speed between two external hard drives on my laptop?

  - by Roman

  Hello, I own Sony Vaio Z laptop with two external USB ports. It's quite new and has USB 2.0 support. I'm using Vista x64 on it. I also have two external usb hard drives, Iomega 500GB and WD for 1TB. Every hard drive has USB 2.0 support. I connect two devices to my laptop and trying to copy date from one hard drive to another. But it takes a lot of time! The speed is about 15 Megabytes per second. I have to wait toooooo long to copy all the information from one hard drive to another. When I try to copy information from my internal (SSD) hard drive, it works fine for both external drives. The speed is very high and it shows me something about 100 Megabytes per second. It makes me feel that USB 2.0 is OK on both drives. But when I'm trying to copy from one external drive to another external, I still get very low speed. I checked out Device Manager and here is the settings I have: (sorry, can't upload image because of my rating, check this url: http://picbite.com/image/122073daljo/ ) I think it's because two of my external drives use the same USB 2.0 controller. Is there any way to make it work faster? Is it possible to move one of my USB ports to other USB 2.0 controller? Or is there any software which can help me to automate copying all the files thru my internal drive? I have only about 3 gigabytes free space on internal drive and it's quite difficult to move manually every file from one hard drive to internal and then again to another internal.

• In a Shell scripts, check version of installed package, make a decision based on output

  - by DJDarkViper

  Looking to write a cross distro / cross version shell script that makes sure a forced version of PHP is installed Example: Ubuntu 12.04 has 5.3, Ubuntu 13.10 has 5.5, Debian 7 has 5.4 I need this script, when run on a distro that has an old version of PHP, to update the repo to point to a package for 5.4, and if the distro has too new of a version, can downgrade to 5.4 appropriately. Im still not entirely comprehensive of Shell/Terminals technical limit of what you can do with it, but ill be perfectly frank that im still not totally used to existing tools The best I can think at the moment is: php -v | grep "PHP 5" but that returns a bunch of potentially changeable granular characters (PHP 5.4.4-14+deb7u5 (cli) (built: Oct 3 2013 09:24:58) ). Im not sure what to pipe to after this to extract out the characters im interested in Im not sure if im being totally clear, im not sure how to ask this.. Basically, in an automated shell script for Linux distros, how do I extract the PHP version (and just the PHP version number preferably) and make a decision based on that output EDIT This line ended up doing pretty dang good php -v | grep "PHP 5" | sed 's/.*PHP \([^-]*\).*/\1/' | cut -c 1-3 Bit long in the tooth, but gives me "5.3", "5.4", and "5.5" which is exactly what I need to work with

• Reliable custom Windows shortcut keys?

  - by Peter Baer

  I have global Windows shortcut keys assigned to several different cmd.exe instances. I do this by creating shortcuts to cmd.exe on my desktop, and assigning each one a unique shortcut key (for example, CTRL + SHIFT + U). Pretty basic stuff. I'm using Win2K8 (R1 and R2). This works just fine... most of the time. But with infuriating regularity, sometimes it doesn't. Or it will work with a long delay (many seconds). It doesn't matter what app currently has focus (it can even be one of the command prompts). It doesn't matter what keys I assign (I've tried a few variations of WIN, CTRL and SHIFT). I did notice that this is often, but not always, correlated with explorer.exe struggling in some way or another (say, an explorer window opened to a file share that's unavailable, or an app being unresponsive, or whatever). In other words the shortcut key handling appears to be very sensitive to unrelated system activity. Note that whenever I have this problem I can always successfully ALT + TAB to the window I want to get to, but that's tedious. I use the shortcuts to these command windows hundreds of times a day so even a 1% failure rate becomes really annoying. Is there a way to fix this, or is there some third-party utility out there that will RELIABLY intercept custom key combinations to bring focus to whatever apps I want, in a way that is independent of other system activity? ADDENDUM: There is a property of the Windows shortcuts that I would not want to lose if switching to a third-party hotkey tool: Windows shortcuts are idempotent. Once you've launched a shortcut to some app, pressing the shortcut key combo again takes you to the already launched process - it does not launch a new process.

• System State Backup Retention Policies

  - by isoscelestriangle

  I was wondering if there was a general consensus on how long to keep system state backups. I am trying to reevaluate our current backup process, and trying to get a good handle on our current storage requirements. Our current setup involves tapes and sending backups offsite with Barracuda Networks. We have been doing our system state backups with Barracuda now, which does full backups daily, leaving our storage requirements growing quite quickly. My boss is a little too gung-ho with backups and wants our system states saved for quite a while. We currently have 5 days of nightlies, 5 weeklies, 3 monthlies, and so on. I think this is quite overkill for system state backups. My boss wants the ability to go back in time to find when an issue appeared, but I don't think that is practical. Many things change in the course of several months. I also think it would be hard not to notice problems with our DCs and other servers for several months. I would think that a previous week's snapshot and the current week's dailies would suffice. Any advice or reading you can point me to? Thanks!

• Connecting to unsecured wireless network

  - by Sanchez

  I would like to know what information is public and can be intercepted in a non-open, but unsecured wireless network. Moreover, is there anything I can do to make it more "secure", other than using https connection whenever possible. In more details, I recently discovered (with surprise) that the wireless network in my school is actually unsecured. Although not everyone can connect to it (you need a student ID), I am told that certain softwares like Wireshark would be able to intercept the data. Since I have been using the network for all private purposes (email, facebook etc), I do feel quite insecure now and would like to understand the situation a bit better. I installed Wireshark and tried to play with it but all I can see are something alien to me. In any case, all I see seems to come directly/indirectly from my IP address, and I have long thought that usually different computers in the same wireless network would be assigned different addresses. Am I wrong? If not, then I feel very confused about what information is actually being captured (potentially by other users in the network, since I don't think I could capture activities of others in the same network anyway), and whether it's safe to use the network at all. (Gambling on others in the same network showing good behaviour is apparently not an option.) Thank you.

• Virtual Machine Network Services causes networking problems in Vista Enterprise 64 bit install

  - by Bill

  I have a Quad-core/8GB Vista Enterprise 64-bit (SP2) installation on which I installed Virtual PC 2007. I have a problem that is opposite of all that I found searching around the Internet--everybody has problems making network connections from their guest VM. When Virtual Machine Network Services is enabled in the protocol stack for my network card across a reboot, it causes access problems to the network. The amount of time to login in using a domain credentialed account is upwards of 3 minutes, then after reaching the desktop the network and sharing center shows that my connection to the domain is unauthenticated. Disabling and re-enabling the Virtual Machine Network Services (uncheck in network properties/apply/recheck/apply) fixes the problem. And as long as I have the VMNS disabled when I shutdown the restart runs smoothly. I just have to remember to enable after login and disable before shutdown. I have un-installed and re-installed Virtual PC 2007 multiple times with restarts between. The install consists of the SP1 + a KB patch for guest resolution fix. Any help would be greatly appreciated. Some additional information... At one point during my hairpulling and teethgnashing with this, I tried to ping my primary DC and observed some weird responses: (Our DC is 10.10.10.25, my dynamic IP was 10.10.10.203) Reply from 10.10.10.203, Destination host unreachable. Request timed out. Reply from 10.10.10.25: ... This is not consistently repeatable, but thought it might strike a chord with someone.

• Virtualization in Ubuntu 9.10

  - by Jeff Dege

  I have an existing Centos 5 installation. I would like to upgrade to Ubuntu. Thing is, I don't want to be down for as long as it will take to get my entire environment moved over - software installed, connectivity configured, etc. I'd like to take it one step at a time. But I don't really want to keep rebooting back and forth from the new OS to the old OS. That's what I did last time I upgraded to a new OS, and it got old real fast. So, since my new MB is virtualization-ready (AMD Phenom II 945 quad-core), I figured I could create a virtual machine, under the new OS installation, that ran the old OS installation. The problem is that the documentation I've been able to find has been pretty sparse. I've found a lot of possibilities, and little info on which would be capable of doing what I want. I have a new Ubuntu 9.10 installation, and a second disk containing the Centos 5 installation. And I don't know where to go next. Any help would be appreciated.

• Computer always freezing after random periods of time. No errors listed.

  - by Wesley

  Hi, all. Here are my specs beforehand: AMD Athlon XP 2400+ @ 2.00 GHz, 160GB IDE HDD, 128MB GeForce 6200 AGP, 2 x 512MB PC3200 DDR RAM, CoolMax 350W PSU, 1 x CD-RW Drive, 1 x DVD-ROM Drive, FIC AM37 Mobo, Windows XP Pro SP3 My desktop freezes after random periods of time but there are no errors listed in the Event Viewer after a forced shutdown and restart. A couple months ago, I found that when it froze, the floppy was being accessed at the same time. So, I disconnected the floppy (since I never used it anyways) from the power supply and motherboard. Everything was working fine and the computer never froze. This past Christmas break, I left for a Conference and when I got home, the computer kept freezing again. So, this time, I just disconnected the DVD reader (from mobo and power) and started it up. Still, it froze almost right away. Then I found some older sticks of RAM (2 x 256MB PC2100 DDR) and swapped them in. Everything worked fine again after that. I even swapped the 2 x 512MB PC3200 DDR RAM back in and everything worked okay. Then it started freezing again, and I tried all possible RAM combos, still freezing within 5-10 minutes of startup. One thing I've realized is that the floppy drive is still listed in My Computer and I uninstalled it from my Device Manager already. There were no software errors, and I uninstalled the most recent software, with no effect. Still, I have no idea what is wrong because everything ran fine before that. Any suggestions? EDIT: Still have yet to buy some blank CD media to use Memtest86+. However, would a lack of virtual memory cause the computer to freeze? EDIT2: So after a long time, I ran Memtest86+ and all is well. Turns out though, after removing my original DVD reader and replacing it with a DVD-ROM drive, there is no freezing whatsoever! Thanks for all your suggestions!

• How to prevent Gnome-shell's Alt+Tab from grouping windows from similar apps?

  - by wleoncio

  I love pretty much everything about how Gnome Shell handles app-switching through Alt+Tab. My one gripe with it, though, is how it forces the user to use Alt+` to switch between windows of the same app. This is very annoying for me, because now I have to keep in mind if the last window I was using belonged to the same app as the current window or not. Definitely a nuisance for power users who thinks in terms of "windows I'm working with" instead of "applications I'm working on". I've tried the AlternateTab extension ( https://extensions.gnome.org/extension/15/alternatetab/ ), but it's looks way too ugly for me. Not to mention that in the end all I want is to remap Alt+(key above tab) to Alt+Tab on this application. I guess one option would be to just tweak Gnome-shell. My guess is that I should tinker with the altTab.js file at /usr/share/gnome-shell/js/ui/, but the file is too long and overwhelming for someone like me, who doesn't know JavaScript. Does anyone know how I can make Gnome Shell stop grouping windows by applications?

• ACER ASPIRE V3-571G-9435 Fan not kicking in leading to overclocking

  - by brythespy

  This laptop has always had this problem. The temperatures kick up to the thermal ceiling of 99C for the CPU (i7-3610QM) and 94C for the GPU (GT 640M). Problem is, the FAN doesn't give a damn. It's actually QUIETER when the temperatures are that high, than when it's at 60C or so. I figured it was a problem with the BIOS, so I updated that, no change. So maybe it was a problem with windows? Nope, same result on gaming with Ubuntu. The major problem of this, is that after gaming for ten minutes the CPU throttles itself to 1197MHz(as opposed to 3193), and the GPU goes down to 135MHz( as opposed to 843MHz). The problem is that the fan won't kick in like I know it can, because when the laptop is in POST, like at BIOS setup, the fan is like a vacuum cleaner it's so loud! I don't really care about noise, so I'd love to have the fan like that all the time as long as the temperatures don't fly through the roof... So, things I've tried so far, to avoid possible duplicate answers. Checked for dust: It's been this way since the laptop was new, and I've since then taken it apart. No dust buildup. Background stuff running?: No, problem persists across OS'es, and it happens while gaming anyways Manually underclocking both CPU/GPU: Using windows, I can force the CPU to stay at 1.1GHz, but the temperature STILL easily hits 99C after 5 min of gaming Contacted Acer support?: No help at all. They told me to update and reset the BIOS, which I have done multiple times. There are only about 6 changeable things anyway, none of which should affect the FAN control Third party fan control program?: None detect the fan So, I'm screwed until I can afford to replace this laptop, but I am very satisfied with performance in games... Whenever the CPU/GPU aren't being throttled. Anyone that can offer advice to solve this problem would be greatly appreciated. Hell, if you solved my problem I'd send you some monies through paypal.

• Is there a better way to do bonded vlan tagged interfaces with XEN

  - by AJ01

  We have a number of XEN servers all running CentOS or RHEL. The VM's that they run are all required to be on their own VLAN for no other reason than the customer expects them to be. Long story short however, I can't change this right now. We are also required to have bonding enabled on the interfaces. So to accommodat this we enslave eth1 and eth2 to bond0. We then create a seperate interface called bond0.VLANID where VLANID corresponds to the correct vlan; eg ifcfg-bond0.204 DEVICE=bond0.204 BOOTPROTO=static ONBOOT=yes VLAN=yes BRIDGE=xenvlan204 Bridge to XEN As you will see, we eventually have to bridge this out to XEN, and we do this by adding another interface called xenvlan204 (in this instance) which contains; ifcfg-xenvlan204 DEVICE=xenvlan204 BOOTPROTO=none ONBOOT=yes TYPE=bridge XEN Vm Config Finally in our XEN config for each VM, we add vif = [ "bridge=xenvlan204" ] This then allows the vm host to access that particular vlan The Problem We've noticed a few problems with this setup. One being that we currently create the interfaces manually. Which means if we add more vlan enabled interfaces and bridges we usually have to restart xend which is something I'm not so hot about. Also lower level staff have their heads melted by the number of interfaces and the risk of a mistake occurring is high. Secondly, it can take sometime for a host to come up if it has a number of vlan taged interfaces. Thirdly, its just not scaling well on the management aspects The Question Is there a better more flexible way to do this (in particular with Xen that ships with centos 5.3, 5.4 and 5.5 as we have to support all three) that leverages either scripting or other solutions to allow an arbitrary amount of interfaces to be created when a vm is instanced. Your advise and expertise is more that welcomed.

• Extremely Weird Computer Problem

  - by waiwai933

  Well, having worked with computers a long time, I thought I had seen everything that could go wrong with a computer. Today, I learned that I was wrong. My Mac has been behaving extremely weirdly. While the keyboard is fine, the mouse holds extremely weird behavior. It will open apps from the Dock, but not open documents from a Stack. The top menu bar will work, but only after I restart Finder. I am unable to close most windows, except with Cmd+Q. Clicking on a link in Safari, for some reason, opens it in a new tab. I can not select checkboxes, but I know a click is going through because you can see a quick indent in the check box, before it reverts to the unchecked state. I've restarted my computer, as well. I don't see a virus when looking through top, but I guess it could be subverting top. Does anyone have an idea what is going on?

• Getting Started in SuSE as an Ubuntu User

  - by Subhamoy Sengupta

  I am not a Linux newbie, but haven't touched SuSE in a very very long time (last time I tried it, it was SuSE 7!). Finally now I felt like giving it a try, and many things seem strange or unnecessarily complex. I have a series of questions. How do I ensure that my packages are uptodate? It sounds silly, but I tried the obvious methods already. I have disabled the default repositories that show up when you do zypper lr, and added Tumbleweed and packman repositories (Essentials, Multimedia, Extra). Then I did a sudo zypper ref --force and then sudo zypper dup, and it tells me many dependencies are not met. I have already added solder.allowVendorChange=true to /etc/zypp/zypp.conf, so it should not care which repository the latest versions are in, and just upgrade to it. Even when I chose to skip the packages with unmet dependencies, and seemed like quite a bit happened in the background, I opened Firefox afterwards and the version was 7! I am guessing things did not go as expected. But of course this is not a problem with SuSE, but I am not understanding the system right. How do I do it right? When I start typing arguments of a command, for example sudo zypper install, when I type sudo zypper ins and keep hitting TAB, nothing happens! It always worked in Ubuntu and I feel very uneasy with this. Is this how SuSE is supposed to be? When I try to install something, and I start writing its name, even though the package exists and I am sure of it, hitting TAB does not autocomplete it. This is also quite inconvenient. Why is it not happening? There are many things in SuSE that are really great, and I think I will stay with it and not go back to Ubuntu once I settle these very rudimentary issues. But right now they are giving me a lot of grief! Please help!

• How to get data from a borked Windows Home Server

  - by harhoo

  Yesterday we had a power surge, followed by a power outage. This left my WHS borked: powering on just gives to a flashing blue light (the led on the power supply also flashes green) - no fan or boot activity, nothing. I urgently needed some files off there in the short term (and the 500GB of photos, music, personal video etc in the long term) so I took the hard drive out and put it in my computer. The files and folders showed up, but I couldn't access them - clicking on an image gave an invalid image error in Picasa, I couldn't play MP3s etc. I changed the ownership and permissions of the files, still nothing. I booted in with a LiveCD, the same: files appear, but won't open. Is there anything else I can do? I'm now wondering if it was just the power cable that's broken, but if so, why can;t I access my files from the hard drive? If it is the power cable, and I replace that and the hard drive, will I have done any harm messing around with ownership and file permissions?

• How to encourage Windows administrators to pick up scripting

  - by icelava

  When i worked as an administrator in my first job, I was frustrated our administration processes with Windows servers were a series of point-and-clicks; we could never match the level of efficiency with the Unix servers which had a group of shell scripts to automate a lot of the work. I soon read about WSH and ADSI and wasted no time learning just how much automation I was able to achieve with scripting. There was a huge problem though - almost none of my Windows colleagues were really interested in learning scripting. They seemed happy with the manually mouse-clicking chores and were never excited at the prospect of using scripts to do the work on their behalf. I struggled to convince them to pick up scripting skills despite the evident increases in efficiency. I left that job in pursuit of a full-time software development career thereafter. Almost a decade on working in various environments and different customers, I still encounter Windows administrators mainly possessing this general "mood" where they would avoid scripting as much as possible. Despite the increasing level of accessibility Windows server technologies are opening up for scripting and automation. I am almost certain the majority of administrators are administrators precisely because they absolutely hate performing any kind of programming duties. What are some means to encourage and motivate administrators that scripting can really help them in the long run?

• Slow RDP after server joins domain

  - by Chris Grove

  We're having RDP issues with Amazon cloud servers that we recently joined to an Active Directory domain. The setup is: A local office network A virtual private cloud in Amazon An IPSec tunnel between the two networks A number of Windows 2008 R2 servers on both networks An AD domain (call it abc.net), with one domain controller in each network. The domain controllers are both new, fresh installs. Before we had the domain set up we had local accounts for the cloud computers which were used for RDP access. Our idea was to get all of the servers on to the domain so we could use domain logins instead of per-server local logins. Before the cloud servers were in the domain, RDP (from the office network or through a VPN to the cloud) worked great. After we joined the cloud servers to the domain, RDP from the office became very slow - a few minutes to log in, long frequent pauses when the interface is unresponsive, generally just a slow and frustrating experience. This is a problem regardless of whether a domain or local login is used for RDP. Oddly, when outside of the office network and connecting to the cloud directly with the VPN, RDP is still very responsive. Any idea why RDP from office to cloud is suddenly very slow after the cloud servers join the domain? What can I look at in our configuration to address this? Any help is greatly appreciated.

• Intermittent Trouble Entering Hibernate on WinXP

  - by kquinn

  My personal desktop, running 32-bit Windows XP SP2 (with 4GB RAM, 2.75GB addressable, swap disabled, hiberfil.sys existing and contiguous on C:\; SP3 is not installed because SP2 has been working fine and I do not want to re-qualify with SP3 just for sheer perversity) typically gets hibernated at night. For a long time this worked great, but recently the machine has had trouble entering hibernation. Sometimes when I press my power button (configured to hibernate), the box will start the procedure for hibernating (i.e., go to the blue "Windows XP" background logo and display a message about entering hibernation), but before displaying the usual blue-on-black hibernation progress bar it will drop back to the desktop. No error messages appear, on screen or in the system log. The only record of unsuccessful hibernation attempts in the system log, which proudly proclaims that "The Windows Image Acquisition (WIA) service entered the running state." once per failed hibernation attempt. The problem is almost certainly resource related: if I then close one or more applications which are running, and repeat the exact same process, the machine will hibernate perfectly. There does not appear to be a reliable high-water mark for virtual or physical memory use, below which the machine is guaranteed to hibernate; it's different every time (though typically, below about 1.1–1.4 GB memory usage seems to be where hibernate succeeds most often). Memory may not even be the relevant resource; as far as I know, it could also be handles or sockets. This behavior is relatively recent: it has only started in the last few months; before then, I could hibernate reliably no matter what the current resource use of the system. This machine claims to have hotfix Q909095 installed, but since the symptoms of my problem match KB909095 rather well, I'm suspicious if this fix is actually working as intended. Any ideas on how to fix this or where to start debugging?

• How to create a mysql database that can contain any character, also different languages

  - by Jakke

  I'm trying to create a database that has to contain articles in different languages. I'm using Mariadb as my server and I know bits of SQL. My knowledge doesn't really cover details like the differences between engines like MyISAM, InnoDB etc or character sets like utf8/16/32, latin 5/7/etc. I do know that the character set has importance, I guess what I'm looking for is an all-encompassing character set and an engine that best deals with this type of content. Also, is there an advantage in storing articles in multiple data rows (equivalent of different pages) to make things a little faster, or would you store a whole article in a single data row. Or does that depend on the size of the articles? Sorry for my noobish question, I know the information is all out on the internet but it would take me quite a long time to research and get a grip on everything. Would be cool if someone with experience could give me a little head start and point me in the right direction. This is for a intranet site, consider the content to be somewhat like a blog (and no, I don't want wordpress or something similar at this point). Not sure if it matters, but I tend to create and manipulate my tables with phpmyadmin, I use apache as web server and it all runs on Linux.

• Mac OS X in Virtualbox says "You need to restart your computer"

  - by humoeba

  I've been trying to figure out for the past week how to get Snow Leopard reliably running in a VM. Right now I am using VirtualBox, and it runs fine for a while, but every once in a while (happened 3 times in the last few hours) I get the "You need to restart your computer" message. Unfortunately, it hasn't even lasted long enough to finish installing the operating system yet. I first tried VMWare, which was a pain to set up. I got it running ok, operating system installed, with the guest tools. Every once in a while though, it just stops running. I click inside the VM, and there's no mouse. It doesn't respond to keyboard input either. I have to reset the VM to get a response. I'm wondering if this is the same error. This happens with both Workstation and Player. Here is the tutorial I used for VirtualBox: http://www.sysprobs.com/iboot-loader-virtualbox-install-snow-leopard Here's the tutorial I used for VMWare: http://bobhood.wordpress.com/2009/12/18/welcome-to-snow-leopard-mac-os-x-10-6-and-vmware-workstation-7/ I'm using an iso for Mac OS X 10.6.3. I have an HP Pavilion dm4 with an Intel Core i7 M640 running Windows 7; VT is turned on. Using VirtualBox 4.0.4 and VMWare Workstation 7.0.1 and VMWare Player 3.0.1 Does anyone know what might be causing this error or how I can fix it? Thanks.

• How can I automatically synchronize a directory tree on multiple machines?

  - by Blacklight Shining

  I have two Mac laptops and a Debian server, each with a directory that I would like to keep in sync between the three. The solution should meet the following criteria (in rough order of importance): It must not use any third-party service (e.g. Dropbox, SugarSync, Google whatever). This does not include installing additional software (as long as it's free). It must not require me to use specific directories or change my way of storing things. (Dropbox does this IIRC) It must work in all directions (changes made on /any/ machine should be pushed to the others) All data sent must be encrypted (I have ssh keypairs set up already) It must work even when not all machines are available (changes should be pushed to a machine when it comes back online) It must work even when the /directories/ on some machines are not available (they may be stored on disk images which will not always be mounted) This can be solved for Macs by using launchd to automatically launch and kill (or in some way change the behavior of) whatever daemon is used for syncing when the images are mounted and unmounted. It must be immediate (using an event-based system, not a periodic one like cron) It must be flexible (if more machines are added, I should be able to incorporate them easily) I also have some preferences that I would like to be fulfilled, but do not have to be: It should notify me somehow if there are conflicts or other errors. It should recognize symbolic and hard links and create corresponding ones. It should allow me to create a list of exceptions (subdirectories which will not be synced at all). It should not require me to set up port forwarding or otherwise reconfigure a network. This can be solved by using an ssh tunnel with reverse port forwarding. If you have a solution that meets some, but not all of the criteria, please contribute it in the comments as it might be useful in some way, and it might be possible to meet some of the criteria separately. What I tried, and why it didn't work: rsync and lsyncd do not support bidirectional synchronization csync2 is designed for server clusters and does not appear to work with machines with dynamic IPs DRBD (suggested by amotzg) involves installing a kernel module and does not appear to work on systems running OS X

• Hard Drive that was used before not detected or accessible in Windows 7

  - by Anders

  Hello SU: My PC crashed for some unknown reason, and I am still working on what caused that. However, I pulled my main (windows) drive from my computer and hooked it up to my roommate's machine and was able to pull the data I needed off of it (i.e. the drive is good). I hook up his drives as they were, I had to turn off his machine and unplug his secondary drive to hook mine up, boot his machine and there is no second drive available in windows explorer. I opened Device Manager to see if for some reason it's drive letter got un-assigned, but there is nothing listed in there except his primary hard drive, his optical drive and one other optical drive which I believe is the virtual drive Daemon Tools made. The drive shows up in the BIOS, however after I restarted his machine again it sits on the "Entering setup....." screen at the load window. The only thing I can think of is that may have messed with stuff is I used this tutorial to create a bootable XP install on a USB drive to install XP on my machine (I am 99% certain that the optical drive in my PC is broken) and maybe it used the other hard drive's letter for the USB drive for some reason, which doesn't make much sense since it was recognized it as a different drive letter before I started the process. It is possible that it used the secondary hard drive's letter for it's work, but once again I am uncertain. Where should I go from here? He his bound to wake up within the next several hours and will probably flip a lid if I cannot get some sort of handle on this. Any and all help is greatly appreciated. PS: Anyone who helps me get this situated has a beer or two on me, as long as you are in the greater metro Detroit area, or don't mind traveling a bit!
