• Increasing Screen Resolution to more than limit and scaling to origional

  - by Akshat Mittal

  I have a laptop, with Screen Resolution - 1366x768 (most common) - I want to increase it further to 1600x900 (or higher), in the same ratio. I want to scale the higher resolution on my current screen to fit it. I found xrandr with command xrandr --output LVDS1 --scale 1.4x1.4, this worked but again resulted to another problem, it does the scaling thing but the cursor is still blocked into the native screen resolution and I am not able to move it further, I found that the bug is already filed here. Also this command was only for Linux, I wanted to do this thing with both Linux and Windows (including Windows 8). I want a similar software that is bug free (at least not a major bug like this) and that supports Windows as well (or two separate software for Windows and Linux). Any help is appreciated and Thanks in advance.

• Does LDAP fit the role of a user database for an application?

  - by Spredzy

  I (my company) run a webservice that integrates pieces of few entreprisey-level software. Most of them offer different type of authentication but all offers at least LDAP. I was wondering if storing my application users directly in an LDAP directory would be a good idea. This way all the application I am using could rely on it for authentication purpose. I am aware that LDAP is not a database per se, but it is a datastore. I am also aware that there is no kind of constraints thus deleting a user on the LDAP directory won't do anything on my actual data, but this case would be taken care of with an extra process. My main question here is : is there any reason why I shouldn't use LDAP as my users database ?

• Network adapters reliability

  - by casey_miller

  Can you help me with understanding of reliability of network adapters. Most of the time servers do have at least 2 NIC's bonded to provide sort of a HA for it. So in case of one NIC fails, the second would still do the job. I wonder which factors work when you use network adapters. I know that, the most important and weakest part of any computer system is: storage (i.e HDD). but how reliable actually network adapters are? There are more expensive ones, and cheaper adapters. In which cases do they actually fail? In what circumstances. May it be a intensive usage of them Time when it's on In your experience how often you found yourself changing NIC's due to their fail? Or just what's the typical lifetime of commodity NIC's? thanks.

• What is the maximum number of TCP connections I can have in Windows Server 2008?

  - by evilfred

  I would like to have as many connections (single connections from many different clients) as humanly possible in a server running on Windows Server 2008, in order to support a Comet-style application. The application is written in C#. The connections will not be chatty, they just need to be open (and stay open). Buying boatloads of memory and fast CPUs are not a problem. As far as I can tell, I will be limited to 65k simultaneous open connections per NIC - the maximum number of ports. Is this accurate? Or can I go beyond 65k connections / NIC somehow? It seems like there are server products for Linux at least that support hundreds of thousands of connections. How do they do this?

• Debug.Assert has locked / hung my IIS6 site - how do I bring it back?

  - by George

  I'm running some C# / ASP.net code on an IIS6 server. The code has triggered a "Debug.Assert", and now my IIS6 server is not responding for this site — at least that's what I strongly suspect given that this was the cause the last time this happened. How do I bring the site back up? Stopping and then starting the site doesn't bring it back — I continue getting timeouts from the proxy, which I think is caused by the site itself crashing. How do I disable Debug.Assert permanently in production? Do I just edit the web.config: <compilation defaultLanguage="c#" debug="false"... — is there anything else I need to do?

• Operating System Not Found - BIOS recognizes, Live OS doesn't (Laptop)

  - by Klaus Borges

  Here's the deal: I have a multi-partitioned hard drive on my laptop set up with GRUB. I got a blue-screen while working on Windows 7 and when rebooting I got the Operating System Not Found error message. I rebooted the computer once again and entered the BIOS setup just to see if recognized my HDD - it did. Next step for me was booting a Live CD and seeing if I could repair GRUB or at least check if something changed on the partitions, but it doesn't seem to recognize anything there. Tried blkid, fdisk -l, not even GParted can see it. What should I do?

• Can I use an nVidia Geforce 9600GT for triple-monitor?

  - by John Rudy

  My work PC has (as you can guess from the title) a single Geforce 9600GT card. According to the spec page for this card, both DVI ports are Dual-Link DVI. Both are currently in use on Dell 19" 1280x1024 screens. I'm running Windows 7, with Aero enabled, for what that's worth. What I'm wondering is if I can use a standard DVI splitter cable to drive a third screen from one of the ports -- specifically a Samsung 22" 1680x1050. I'm really outgrowing the two-screen setup, and am strongly considering bringing in my home monitor (which is almost never used) to bolster my usable space. If I can't, then my alternative is to replace one of these Dells with that Samsung, to give me at least a "little" more space. (Before you ask, there's probably no chance I can get my company to spring for a second video card and third monitor. Even if I could, it would not be politically expedient, as a number of my other coworkers are already pretty jealous at my setup.)

• Router which can modify TTL

  - by TheMouse

  My ISP has set up the TTL to 1. My current router Linksys WRT120N can't change this and my computers don't have connection to Internet. I will return my current router and take another. I have some options: D-Link DIR-615 D-Link DIR-320 Linksys WRT54G2 Linksys WRT54GL Is the last router the only fix (among these routers) to my problem? ( I have to buy the router from this shop: http://laptop.bg/#/accessories/routers/ .. the site is in Bulgarian but at least the models which I can choose from are there in English.)

• PC won't post after replacing mobo

  - by Dan

  I am trying to fix an older HP desktop (~2 yrs old) that didn't seem to have video working. The video card on the machine was integrated. After some debugging, it looked to be the mobo, so I went out and got a new one (also with integrated video). Now, it pretty much does the same thing. Here's the symptoms: no video, doesn't post at all, fans DO spin (both chasis and CPU). Any other ideas? I suppose it could be the CPU, but I would think if it was, it would at least post.

• Can installing URL Rewrite 2.0 on production IIS 7.5 have a negative impact?

  - by Olaf

  We have a Windows 2008 R2 server with IIS 7.5 and a lot of customer websites. Being no sys-admin but a developer, I hate to touch that wonderfully running system. However, I'd like to update the IIS plugin URL Rewrite to version 2.0 via Web Platform Installer. I do not want to do anything that might compromise the server, hence the question: can I expect it to work with at least a 99% chance? I did not find any bug reports or reviews on the web, so I'd like to hear an expert on that.

• How can I use fetchmail (or another email grabber) with OSX keychain for authentication?

  - by bias

  Every fetchmail tutorial I've read says putting your email account password clear-text in a config file is safe. However, I prefer security through layers (since, if my terminal is up and someone suspecting such email foolery slides over and simply types "grep -i pass ~/.*" then, oops, all my base are belong to them!). Now, with msmtp (as opposed to sendmail) I can authenticate using the OSX keychain. Is there an email 'grabber' that lets me use Keychains (specifically the OSX keychain) or at least, that lets me MD5 the password? This is a duplicate of my unanswered question on serverfault. I've put it on superuser because I'm doing this on a personal computer (viz. with OSX) so it's more of a superuser question.

• I have a server running Windows 2008 R2 Core and it needs to hosts either SVN or GIT

  - by Jason Adams

  The server allocated for our cross platform projects (both Mac & PC) source repository is running Win2008R2 Core. We're really happy with its stability and we aren't interested in moving over to non-core. We need to get either SVN or GIT installed on the aforementioned box in the shortest amount of steps. We know the advantages/disadvantages of both systems. That being said, we don't care which one we use, we're just are looking for the path of least resistance on setting up a repository on a machine running R2 core.

• Best practices for setting lm-factor in Squid refresh patterns

  - by Mpentecost

  I am running a Squid (3.1) cache in front of Django. The content of the site does not change very often, so Squid gives our backend much needed breathing room. Currently, this is the refresh pattern that we are using to cache the content: refresh_pattern . 60 100% 60 We basically want to cache everything for at least an hour (and only an hour) before Squid then re-validates the content. My question is on the "100%" parameter, which sets the lm-factor. I'm not sure if setting that to 100% is doing what we want it to. The assumption was that by setting it to 100%, it would ensure that objects stay in the cache for the max cache time. Is this an incorrect assumption? What are the best practices that one should follow when setting up a refresh pattern like this?

• how do I update php on centOS?

  - by matteo

  I have php 5.1.6 installed on a centOS server, and I need at least 5.3.2 (but would rather install the latest available 5.* version). If I run yum update php it says it will update to 5.1.6-34.el5_8 (mine is 5.1.6-27.el5_5.3)..... what the heck???? Are the available packages for centOS THAT much behind the current version, or is it because yum will by default only update within the subversion after the second dot (or something) and I need to tell it to give me a more recent version? If so how do I do that?

• Looking for Mini itx capable of running Photoshop + Illustrator (cs4 or higher)

  - by drozzy

  Ok, so I want to build a small pc for my gf that she can take with her instead of the crappy laptop that she has. Overall I think the complete system should not weight more than 10 lbs. The requirements are to run at least 4 applications simultaneously, and be able to switch between them with no problems: Photoshop Illustrator Word editor Browser Should be able to handle 1920x1200 resolution. I am currently looking at LGA775 socket as I can just transfer my desktop cpu Q6600 to it. Currently deciding between DQ45EK and DG41TX, but any other suggestions are welcome. So I am thinking something along the lines of: MINI-BOX M350 Case with 90 watt psu Q6600 cpu (my desktop cpu) 2x2GB kingston ram (or similar) Video? Need external or built-in G45 on DQ45EK will do? My primary concern is whether the 90WATT is sufficient of the Q6600? Thanks

• Network-Backup-Software with file versioning and web-interface

  - by dlang

  Dear All! I would like to backup our business-data to a remote backup-server. We would like to set-up our own backup-server running on any operating system (windows appreciated) which comes with a web-interface, that enables to restore individual versions of one file. Because budget is limited, an open-source software or at least a cheap software is a must! Unfortunately I couldn't find even a single software, which fulfills the requirements of file versioning and web-interface for single file-restore. Do any of you have already set-up such a system? Best regards, Daniel Lang

• Missing disk space in Windows XP

  - by Jørn Schou-Rode

  On my mother's Lenovo laptop, Windows XP claims that the hard drive is almost full. According to the properties window, 52.7 out of 55.2 GB is in use: By deleting temp files from Internet Explorer, System Restore, Recycle bin, Windows Update, System Cleanup, I managed to free up about one GB. That's still 50 GB in use, which still is a lot more than I expected. Hence, I gave good old WinDirStat a spin, and here's the output: It might be hard to read here, but the first line says that the total amount of disk space in use on drive C is 24.3 GB. So Windows claims usage of 52.7 GB and WinDirStat can only account for 24.3 GB. Where is the other half of that disk space being used? I hope someone has an answer, or some tricks or tips to do further research. UPDATE: The laptop in question has an SSD hard drive. I am aware that these disk (at least the earlier ones) have a limited life-time. Could the symptoms described be caused by wear and tear on the SSD?

• show php error message on IIS 7

  - by Max

  I am using IIS as a webserver on my development machine for PHP webdevelopment. Or at least, I am trying to. When there is a syntax error in a PHP script and I open that file in my webbrowser, I just get an 503 "internal server error" and the default IIS error page for this error. Some browsers dont open that file at all, possibly because of the 503 HTTP Response Header. I would like IIS to act in that case just like the apache webserver: display the PHP file with the error anyway, so that the error message gets printed out. How can this be done? EDIT: PHP settings: display_errors is on and error_reporting is set to E_ALL

• Choose an output audio device different from the default on WMP 11

  - by GetFree

  I like to play my music through a Hi-Fi audio equipment and everything else (like windows sounds, web videos and such) through my default PC speakers. On WIndows XP I had WMP 9 and I could do that with no problems since I can choose what audio device (which sound card) to use, and that selection is for WMP only, which can be different from Windows' default audio device. But now that I have Windows Vista and WMP 11 I cannot longer choose an audio device just for WMP, or at least I can't find a way to do it (the control in the options dialog is no longer there). Was this useful feature really removed from WMP 11? or there is some other way to do it?

• Alternative terminal emulators for OS X

  - by Joseph Silvashy

  This might sound ridiculous, but my eyes are tired of looking at the crappy font rendering in OS X's Terminal.app, is there anything you guys recommend? I know it's like one of those things that you can easily say, "It's shell! what more can you ask for!" but really, all these great methods for rendering fonts and anti-aliasing, and we developers haven't even integrated that into our most trusty tool... at least that I know of. Anyhow, let's discus shell alternatives, thoughts?

• How can I remove OLD history from Google Chrome?

  - by Norman Ramsey

  I'm working on a laptop with a modest hard drive, and 500MB is taken up with Google Chrome "History Index" and "Thumbnails" files. Some of these files are a year old. Chrome offers me the option to remove recent history, but I want the opposite: I want to remove old history. (Ideally I would remove the least recently used history information, but I don't expect to be able to do that.) Anyone have any ideas? I'm running the standard Debian google-chrome-beta package.

• Collect and Backup Photos from Multiple Photographers

  - by Graviton

  I have a few photographers working under me ( well, not exactly under me, but I say it anyway just for illustration purpose), so they shoot a lot of photos, the problem is that they all store their photos on their hard disk, and I have no way to retrieve them unless I pass them an USB and ask them to fill it with their photos. Very labor intensive and inefficient! Is there any other better ( more automated) ways of doing this? For the fear of losing the resolution, I don't really favor a online-synch approach, because I think all the photos uploaded to any website will suffer a resolution loss, which is the last thing I want. Is there a better idea? Edit: Being artistic as they are, I can't guarantee that they all use PC and Windows; so the software must at least be able to run on Mac.

• Installing ruby 1.9.1 on OS X with RVM, getting error I can't make sense of

  - by Pselus

  I'm trying to update my ruby install on Leopard to at least 1.9.1. I found a tutorial that tells me how to do it with RVM and I get as far as downloading, configuring and compiling the version I want, but during the compile I get errors.

• Reliable 1tb or larger hard drive?

  - by jasondavis

  I am in the market for 2-3 new drives, I would like each to be at least 1tb to 2tb in size. I have been reading all the reviews on newegg.com for 1tb and larger drives and they all have 1 thing in common. Almost all the ones I read about have complaints of them being DOA or dieing within a few weeks of use. I am hoping to find some drives with this storage range that have a reputation for lasting a long time instead of a short life. Please help me if you have any experience with these sort of drives? Most the ones I read about were Western Digital brand. I realize some might complain that this questions answer would be based upon a timeframe, so if a user searches and find this answer a year from now it will be outdated but I would appreciate any help based on the current hard drives available as of April 10th, 2010 on newegg.com

• How can I see logs in a server after a kernel panic hang?

  - by Low Kian Seong

  I am running a production gentoo Linux machine, and recently there was a situation where the server hung in my co-located premises and when I got there I noticed that the server was hung on what appeared to be a kernel panic hang. I rebooted the machine with a hard reboot and was disappointed to find out that I could not find a shred of evidence anywhere on why the machine hung. Is it true that when I do a hard reboot the messages itself will get lost or is there a setting I can do somewhere say in syslog-ng or maybe in sysctl to at least preserve the error log so that I can prevent such mishaps from happening in the future ? I am running a 2.6.x kernel by the way. Thanks in advance.
