• Graphics card failure, anything I could try...

  - by ILMV

  My gaming PC has decided to die, it's not the first time but usually a quick ATX reset brings it back to life. Today it didn't. I disconnect all unessasary devices so I've only got the case button / LED cables, GPU, CPU, RAM and power connected, the computer still didn't turn on. I've not got a speaker on my motherboard so found a spare one I have for testing and when the machine starts up I get one long beep and two short beeps from my Award BIOS, which apparently means a video card error. I change it with the GPU from another machine and all works well. Q: So I have a faulty graphics card (an nVidia 8800GT OC), is there anything I can try to resurect it?

• Alternative to Windows Home Server (WHS) backups

  - by Adam Tegen

  Since Microsoft announced the end of life for WHS, are there any alternatives? Specifically, I am interested in recovering from a catastrophic disk failure with WHS. For example, this is my ideal scenario when a desktop hard-drive fails (has a bad virus, etc): Install a disk of the same size or greater Boot the desktop with the Recovery Disc Point the recovery application at the WHS Pick the machine, the drive(s) and the date of the backup Have a couple beers Reboot to a working machine as if nothing happened. I would need to slap multiple disks in the machine without raid. It sounds like LVM will work here. It would be nice, but not required to have de-duplication of files when multiple machines are backed up. (Single Instance Storage)

• Setting up Windows 2008 with VPN and NAT

  - by Benson

  I have a Windows 2008 box set up with VPN, and that works quite well. NPS is used to validate the VPN clients, who are able to access the private address of the server, once connected. I can't for the life of me get NAT working for the VPN clients, though. I've added NAT as a routing protocol, and set the one on in the VPN address pool as private, and the other as public - but it still won't NAT connections when I add a route through the VPN server's IP on the client side (route add SomeInternetIp IpOfPrivateInterfaceOnServer). I know I can reach the server's private interface (which happens to be 10.2.2.1) with remote desktop client, so I can't think of any issues with the VPN.

• What's the fastest way to get CRUD over CGI on a database handle in Perl?

  - by mithaldu

  TL;DR: Want to write CGI::CRUD::Simple (a minimalist interface module for CGI::CRUD), but I want to check first if i overlooked a module that already does that. I usually work with applications that don't have the niceties of having frameworks and such already in place. However, a while ago i found myself in a situation where i was asking myself: "Self, i have a DBI database handle and a CGI query object, isn't there a module somewhere that can use this to give me some CRUD so i can move on and work on other things instead of spending hours writing an interface?" A quick survey on CPAN gave me: CGI::Crud Catalyst::Plugin::CRUD Gantry::Plugins::CRUD Jifty::View::Declare::CRUD CatalystX::CRUD Catalyst::Controller::CRUD CatalystX::CRUD::REST Catalyst::Enzyme Now, I didn't go particularly in-depth when looking at these modules, but, safe the first one, they all seem to require the presence of some sort of framework. Please tell me if i was wrong and i can just plug any of those into a barebones CGI script. CGI::CRUD seemed to do exactly what i wanted, although it did insist on being used through a rather old and C-like script that must be acquired on a different site and then prodded in various ways and manners to produce something useful. I went with that and found that it works pretty neat and that it should be rather easy to write a simple and easy-to-use module that provides a very basic [dbh, cgi IN]-[html OUT] interface to it. However, as my previous survey was rather short and i may have been hasty in dismissing modules or missed others, i find myself wondering whether that would only be duplication of work already done. As such i ponder the question in the title. PS: I tend to be too short in some of my explanations and make too many assumptions that others think about things similarly as me, resulting in leaving out critical details. If you find yourself wondering just what exactly I am thinking about when i say CRUD, please poke me in comments and I'll amend the question.

• HP dv6000 laptop powers on only if plugged in

  - by Ben

  My HP dv6000 laptop will not run on battery power. It will only run while plugged into the wall. I have already replaced the battery, but it still will not operate on battery power. The problem began slowly. The original battery's life got shorter and shorter, until eventually it would only last ~45 seconds before going into hibernation. Finally, the battery would not work at all, so I threw it out and just used it without a battery. I bought a replacement recently.... but the problem persists. When I connect the new battery to the system, the "charging" light turns on for about 30 seconds, then goes dark. I'm assuming there's something wrong with the internal charging circuitry? If this is the case, how would I go about fixing this, short of buying a new motherboard? If anyone could give me some assistance in confirming/rejecting my diagnosis I'd be very appreciative! :)

• Considerations for a business looking to transition from PSTN to IP Telephony

  - by Bryce Thomas

  Full disclosure - This is related to a homework assignment question. I am not asking you to do my work for me, I am merely looking for some pointers and considerations to direct me in my further research. I have an assignment I'm working on where I've been given a scenario where a business wants to look into transitioning to using "Internet Telephone" as opposed to a traditional PSTN/PBX system and I need to write a report on it. I'm after some high level pointers from people, especially anyone that has been involved in a real life transition of this nature, on what some of the most important considerations are. These can be financial considerations, initial setup considerations, ongoing administrative considerations, quality of service considerations or anything else that is pertinent to performing such a transition.

• Is there a work around to configure brightness or color on a DisplayLink monitor?

  - by shaneykakes

  I run 3 monitors in addition to my laptop display at work - two of the monitors are using DisplayLink adapters. I've always thought that all my displays were too bright (and possibly give me headaches?) - even after I reduced their brightness as far as possible using the monitor menus and the nvidia software control panel. Recently I installed f.lux - I love it's "halogen" color profile which has improved my life considerably. The problem is that f.lux has no effect on/will not adjust the color & brightness of my two DisplayLink monitors. F.lux has a faq (#4 under troubleshooting) that addresses this - saying DisplayLink has no support for color calibration so f.lux only works with monitors "directly connected to your computer". Does anyone know of a work around? Specifically a way to use windows color management/profiles (or some other software) to adjust the brightness/color tone of DisplayLink monitors? Thanks in advance!

• Recurring events repeatedly saves a draft every minute

  - by Henrik Rasmussen

  Using Outlook 2010, some of my recurring (planned, not drafts) events is saving a draft to my Drafts folder every single minute as long as it's active. An example taken from real life is that I have a calendar entry (Appointment) occuring every day from 24-09-2012 until 28-09-2012 from 08:00 to 16:00 (GMT+1) with a blue category, only one participant (me) with subject but without a place. So every minute from 24-09-2012 until 28-09-2012 from 08:00 to 16:00, but not from 16:00 to 08:00, a new draft is automatically saved in my Drafts folder. How do I get rid of that behaviour? Addition here: Removing the offending event just allows a new one to take its place. There doesn't seem to be much on the sites - Microsoft calls it a "personal" issue, but there are more and more instances.

• Turning off Chrome's visual effects

  - by Wesley

  Is there any way to turn off the visual effects used by Google Chrome? For example, the tabs slide around smoothly, the scrolling is really smooth, and there is a huge arrow that fades in and out during download. Reason why I'd like to know is primarily because I want to maximize battery life on my netbook by using less visual effects and, secondly, because I use Chrome on slower systems and would like to maximize the performance and efficiency of Chrome. This applies mainly to Windows XP, but also Vista, 7 and even (X)Ubuntu 9.10. EDIT1: Oh yes... disabling the attaching/detaching of tabs and turning them into translucent in the process. That's a bit stressful on my slower machines.

• Worth it to move /var to physical disk vs logical?

  - by Tammer Ibrahim

  Brief question about partition layout. I use an SSD for /, /boot, /usr, & /home partitions. I'd like to move /var to a mechanical disk to minimize writes to the SSD. I'm mainly concerned about maximizing drive life rather than maximizing performance (although I obviously wouldn't want to cripple my server). My mechanical disks consist of two drives sharing LVM, and a third used for nightly rsync backups. I also have a bunch of old 2.5in hard disks lying around. My question is, should I simply create a new LVM volume '/var' on my primary data store, or would it be worth the increased energy consumption (in terms of maximizing the lifetime of the LVMed drives) to install a low volume 2.5in disk to use just for /var? On a more general level my question is about the trade offs of placing OS mounts on the same physical volumes as my data. Thanks for any help!

• What is the best way to determine the path to the ISV directory?

  - by Luke Baulch

  MSCRM 4.0 Problem: I'm currently storing xml files in the ISV directory along with my web applications. From a plugin (or potentially a seperate app), I need to find an easy way to navigate to the ISV directory to read these xml files. This routine will be called extremely often, so processing minimization should be a strong consideration. Potential solutions: Registry: There is a registry key called 'WebSitePath' with the data 'C:\Inetpub\wwwroot\CRM'. Could potentially use this to build the path. (Will this be the same on all systems/installations?) IIS directory data: Looping through the DirectoryEntries of path '"IIS://localhost/W3SVC"' I could obtain the the web application where description is equal to "Microsoft Dynamics CRM". (Will this be the same on all systems/installations?) Webservice: Create one to read and return the data contained in these xml files The webservice would have easy access to its executing directory. Database: Store the data of these files in the database. Help: Can anyone suggest a simpler solution to obtaining and reading a file from the ISV directory? If not, which of the above solutions would be the quickest to process? Thanks for any and all contributions.

• Screen startup apps

  - by stillinbeta

  I know that most people don't bother with things like screen anymore, but I happen to really like it, even in this GUI day and age. I still do most of my development from a BASH prompt, so it's extremely useful to me. What I'm wondering is what the easiest way is to start an instance of screen (stored in a shell script or .screenrc or somewhere else) so that it starts up with set commands already running in set windows. For example, I use a django test server, so I'd like one window to come up running "python manage.py runserver" and another blank, waiting for commands. The man page is wholly indecipherable. These old unix utilities can do quite nearly everything, so I'm sure this is possible, but I can't for the life of me figure out how. I

• Can't access an internal IIS web site via IP address, only hostname

  - by chris-untrod-com

  I have a machine on my home network running Windows Server 2008 (IIS7) with a web application running under default website called HTCOMNET. The network is just on a Windows Workgroup. The server is named nas1 and has a (dynamically assigned) IPv4 address of 192.168.2.12. I can ping 192.168.2.12. When I ping the machine by name ("nas1"), the hostname resolves to an IPv6 link-local address (as opposed to the ipv4 address). In a browser, I can go to http://nas1/HTCOMNET/ and IIS serves the site, no problem. But if I go to http://192.168.2.12/HTCOMNET, no dice. I have all the windows firewalls turned off. Any idea what's going on? I can't for the life of me figure out why I can't hit IIS via the IP. I feel like it's something really obvious, but i can't figure out what. Thanks!

• Amazon EBS root volume persistence

  - by hipplar

  When I launch a new Windows EC2 instance I am given a 30 gig root EBS volume. I'm trying to make sure I understand the EBS terminology and want to make sure I understand this correctly: Q: What happens to my data when a system terminates? The data stored on a local instance store will persist only as long as that instance is alive. However, data that is stored on an Amazon EBS volume will persist independently of the life of the instance. What exactly does "instance is alive" mean? If I write files to the root volume and reboot the instance will the files remain? Or do I physically have to terminate (delete) the instance for the root volume to go away? Thanks

• pdftk utility and batch file

  - by duhaas

  I cant for the life of me figure out what I'm missing. I have the following batch file: As you can see, when I run this batch file from my desk against a mapped drive it runs just fine: When I run the same exact batch file on the server itself, the place where the mapped drive is located on, it doesnt run and makes me think I have a syntax problem: I just dont understand whats going on, and my eyes are having a hard time keeping track of what might be diff. The server where it isnt working is windows 2003, my desktop where the same batch file is working is Windows 7. Here is the batch file, nothing crazy: FOR /D /r %%G in ("*") DO pdftk "%%G\*.pdf" cat output "%%G\Report.pdf"

• How to maintain an ordered table with Core Data (or SQL) with insertions/deletions?

  - by Jean-Denis Muys

  This question is in the context of Core Data, but if I am not mistaken, it applies equally well to a more general SQL case. I want to maintain an ordered table using Core Data, with the possibility for the user to: reorder rows insert new lines anywhere delete any existing line What's the best data model to do that? I can see two ways: 1) Model it as an array: I add an int position property to my entity 2) Model it as a linked list: I add two one-to-one relations, next and previous from my entity to itself 1) makes it easy to sort, but painful to insert or delete as you then have to update the position of all objects that come after 2) makes it easy to insert or delete, but very difficult to sort. In fact, I don't think I know how to express a Sort Descriptor (SQL ORDER BY clause) for that case. Now I can imagine a variation on 1): 3) add an int ordering property to the entity, but instead of having it count one-by-one, have it count 100 by 100 (for example). Then inserting is as simple as finding any number between the ordering of the previous and next existing objects. The expensive renumbering only has to occur when the 100 holes have been filled. Making that property a float rather than an int makes it even better: it's almost always possible to find a new float midway between two floats. Am I on the right track with solution 3), or is there something smarter?

• Kerberos and/or other authentication systems - One time logon for all PHP scripts

  - by devviedev

  I'm managing a set of web apps, almost exclusively written in PHP, and would like to find an authentication platform to build a role-based authorization system on top of. Also, I'd like the authentication system to be extensible to use for, for example, system services (SSH, etc.) Here are some of the main characteristics I'm looking for, in order of importance: Easy PHP implementation (storing/reading easily roles, etc.). Redundant, if possible. If an auth system goes down everyone is not locked out. Has clients for Windows and Mac. Easy web-based administration (adding/removing users/roles, changing passwords). If not, I can build an administration system without too much effort. One-time log on. I'd also like, when an auth token is issued, to store the user's IP address and use that to authorize the user for some non web-based applications. For that reason, I'd like a desktop client to issue the token and revoke tokens when, for example, the user becomes idle at their workstation. I'm thinking Kerberos might be a solution, but what are other options?

I've swapped the PC units around so know it's not a faulty unit. I've followed the suggestions in the online Lexmark manuals and even called the Lexmark helpline but to no avail. any suggestions? Printer was fine until it gave me a PC unit life warning and I renewed them. Thanks.

• Where can I learn various hacking techniques on the web?

  - by Carson Myers

  I would like to try my hand at hacking -- that is, exploiting various website vulnerabilities. Not for any illegal purpose mind you, but so I can have a better understanding and appreciation of these exploits while writing my own web software. I seem to recall that there was a community that hosted a bunch of demo websites, and you had to find and exploit certain vulnerabilities with each one. I can't remember what it is called but this is the sort of thing I am looking for -- I have read a tonne of little XSS and CSRF examples but have yet to find a real-life hands-on example of one. Does anyone know of such a place, where I can be given an example page and look for security holes? I would really rather not try this with actual websites, I don't want to break any laws.

• Kanji characters appear as boxes

  - by s3d10s

  i'm having trouble with the display of japanese characters on Windows 8 Pro (English, 64-bit, updated regularly). They appear as boxes (picture) in windows explorer, windows menus (even in the language settings of control panel), iTunes and nearly everywhere else, besides web browsers. I was using windows 7 until now, and it didn't have any of these problems, and i'm using the same applications now, as i was using in windows 7. Sometimes (!) when i restart the machine the problem goes away, but that isn't a real solution. What i've tried so far: added japanese language to windows of course installed/uninstalled/reinstalled japanase language pack (didn't have any impact though) i've read in one of these superuser topics a possible solution, when i had to create a txt file on the desktop with a kanji in the filename - that also didn't work (but i honestly hope that hacking and tweaking an operation system released in 2012 can't be the solution to display kanjis..) Please give me any ideas, i'm a bit hopeless here, and don't want to spend my life installing operation systems..

• How to test an application for correct encoding (e.g. UTF-8)

  - by Olaf

  Encoding issues are among the one topic that have bitten me most often during development. Every platform insists on its own encoding, most likely some non-UTF-8 defaults are in the game. (I'm usually working on Linux, defaulting to UTF-8, my colleagues mostly work on german Windows, defaulting to ISO-8859-1 or some similar windows codepage) I believe, that UTF-8 is a suitable standard for developing an i18nable application. However, in my experience encoding bugs are usually discovered late (even though I'm located in Germany and we have some special characters that along with ISO-8859-1 provide some detectable differences). I believe that those developers with a completely non-ASCII character set (or those that know a language that uses such a character set) are getting a head start in providing test data. But there must be a way to ease this for the rest of us as well. What [technique|tool|incentive] are people here using? How do you get your co-developers to care for these issues? How do you test for compliance? Are those tests conducted manually or automatically? Adding one possible answer upfront: I've recently discovered fliptitle.com (they are providing an easy way to get weird characters written "u?op ?pisdn" *) and I'm planning on using them to provide easily verifiable UTF-8 character strings (as most of the characters used there are at some weird binary encoding position) but there surely must be more systematic tests, patterns or techniques for ensuring UTF-8 compatibility/usage. Note: Even though there's an accepted answer, I'd like to know of more techniques and patterns if there are some. Please add more answers if you have more ideas. And it has not been easy choosing only one answer for acceptance. I've chosen the regexp answer for the least expected angle to tackle the problem although there would be reasons to choose other answers as well. Too bad only one answer can be accepted. Thank you for your input. *) that's "upside down" written "upside down" for those that cannot see those characters due to font problems

• Automated method to convert .reg registry file to reg.exe commands

  - by nhinkle

  Occasionally I need to put registry entries into batch files to use in login scripts, unattended installers, etc. While it's pretty easy to add one or two registry commands to a batch file using reg.exe, when there is a large amount of registry data, it becomes tedious. I usually just end up merging an external reg file in those cases, which I would like to avoid, since it ruins the self-contained nature of the batch file. Does anybody know of any tools which can automatically convert a .reg file to a series of REG ADD and REG DELETE commands? This would make life a lot easier! Thanks.

• Ubuntu Nvidia Xorg Twinview doesnt like my monitors

  Basically, using the latest available ubuntu drivers (195.36.15) I cannot for the life of me get my two monitors to operate at suitable resolutions. When not using the drivers atall and going single-screen, both monitors support 1680x1050, but this option is only shown for one monitor in nvidia-settings, and when i manually add a metamode into the xorg.conf, it just gives up initialising the second screen.
