• Tuning WebServer Response -

  - by Vedran Wex Maricevic

  I have this sam e question on StackOverflow and I was advised to ask it here hoping for more information. Here is the question: I am in rather unfavorable situation. I have aspdotneststore front e-commerce application and search addon called VibeTrib. I dont have source code for both of those. Store that runs on StoreFront and VibeTrib has close to 250k products. Also we have lots of filters. I spoke to ViTrib reps, and they want extra money so they could optimize Queries that they use. Money they require is nto a big deal, but the problem is I dont trust them anymore. What we got is much different then wha is being advertised. To cut the long story short. I am runing the store on Amazon AWS now, and regardless of what DB (MsSQL 2012) server I set (I tried 32GB RAM monsters instances) it is slow. Ajax search uses Full Text search and it displays search keywords relatively fast, but once the search is performed ( to display all results) it is still slow.!!! There is something that I could to do accelerate the speed on my own end? I do have full control over EC2 Instance (Web server Server 2012 and IIS 8). Can I set IIS to step in for the search and cache some of it? I was hoping to cache at least some most common words. My best bet is IIS 8 :) Is there any help in my case? Thanks

• DisplayPort to DVI not working on Quadro FX 580

  - by kaosvid

  I have a PNY NVIDIA Quadro FX 580 graphics card with 1x DVI and 2x DisplayPorts. The DVI port works fine with both my Viewsonic monitors but I cannot get either of the DPs to work using the supplied DP to DVI adapter; all I get is a "no signal" on either monitor when connected to either DP port. The NVIDIA Control Panel shows that the second monitor is not connected when in fact it is. How do I get the second monitor to work?

• Why would TCP wrappers stop working for sshd?

  - by toby1kenobi

  On a couple of CentOS 5 servers sshd seems to have become 'unwrapped' - previously I was using TCP wrappers and hosts.allow/hosts.deny to control access, but these are now not being used. If I execute $ldd /usr/sbin/sshd | grep libwrap $ it outputs nothing, whereas on servers where TCP wrappers are still working I see libwrap.so.0 => /lib64/libwrap.so.0 (0x00002b2fbcb81000) Does anyone know what might cause this, or how it could be rectified? Updated As requested: $ rpm -qV openssh-server S.5....T c /etc/pam.d/sshd S.?....T c /etc/ssh/sshd_config S.5..... /usr/sbin/sshd

• Server 2008 R2 file access permissions

  - by Napster100

  I'm finding it awkward to sort out permissions for file sharing and access on my LAN. I've created an account on the server node (as a normal user) and shared a drive that has 2 folders at the root, one is for personal file storage and the other shared files, if I connect to the shared area from a workstation running windows 7 and log-in using the account I created on the server, I can look through directories but can't look in some (which I wanted as I changed the permissions for that to happen), but my problem is although the permissions are set for this user account to have full control of the specific folder I can't create a folder in that area or upload files to that folder. Could someone explain why this is? Thanks in advanced

• How to emulate a domain name - Webmin Setup

  - by theonlylos

  I am currently working on a client project where they are using a custom CMS which relies on having the specific domains configured for it to work properly. So in English, that means that when I try running the site on my test environment, the entire website fails because it isn't located on the primary domain (and I'm pretty sure the domain is hard coded since there's no control panel to adjust the file locations). Anyway what I wanted to ask is whether it is possible to use my test environment URL but have Apache and the DNS emulate my clients website URL locally, rather than calling the actual name servers. Right now I have a virtual host setup in Apache but I am not sure where to go from there. Any assistance is greatly appreciated.

• Moving to an outside Exchange provider - How to create new Outlook profile on multiple PCs?

  - by imagodei

  Following an acquisition we are switching from our local Exchange to an outside provider. I need to change account settings / create new profile so that users are able to access their new mailbox, and I hate the idea of doing it manually on every single client. I have tried quick and dirty solution with copying profile information from Registry on one computer to the other, hoping that I could fix user info later. Quite obviously, this didn't work: Outlook recognized the profile, I could select it at the application startup, but there the fun ends - the profile was corrupt. I couldn't change settings in Mail settings on Control panel, either. Didn't find any Group policy solution. Is there any application, script or other solution, that would help me save time commuting from one PC to the other and typing the same info over and over again?

• Windows 8 Permissions

  - by Dane Balia

  I, 2 days ago, completed a standard Windows 8 installation. It was a fresh install, however Windows 7 was on the disk prior to which it migrated to Windows.old. But for some strange and weird reason, I am struggling to 'write' to my disk in regards to .NET Applications. It appears that none of my .NET (self-written) applications can write to their log files on disk, which are created on startup. I have disabled UAC, as well as set Full Control over Disk C: for my User, but no luck. I keep getting the error: A required privilege is not held by the client. I did google and try some online tuts - but no luck! Thanks

• Which metric/list should be used to evaluate whole software development team?

  - by adt

  Title might be seem vague, so let me tell you a little bit history what i am trying to clarify question. I have been hired as a consultant for a corporate's small developement divison ( The company also owns a couple of software dev. companies) My ex manager runs a BI team, with reportes, analyts and developers. He asked me to evaluate overall design, software developement process and code quality . Here what i found, Lots of copy/paste code everywhere ( no reuse ) Even though they have everything TFS, VS Ultimate etc, No Build process , No Cruise Control.net / team city... No unit tests Web Pages with 3700 lines of code, Lots of huge functions ( which can be divided into smaller one's ) No naming convention both db and c# code No 3r party or open source project No IoC No Seperation Of Concerns No Code Quality Check ( NDepend or FxCope or nothing ) No Code Review No Communication within the team They claim they wrote an application framework ( 6 months 3 persons), but I would hardly call a framework ( of course no unit test, there are some but all commented out). Framework contains 14 projects but there are some projects with 1 file 20 lines of code . Honestly, what people are doing fixing bug all thr day( which will provide more bugs eventually), they are kind of isolated from community, some team members even dont know github or stackoverflow they probably went there with google but they dont know about it. So here is question, Is This list ok ? Or am i being picky? Since I dont have any grudge against them, I just want to be fair, honest and I would like to hear you suggestions, before I would submit this list. And since this list also will be review by software division's manager, I dont want any heart break or something like this. http://www.hanselman.com/altnetgeekcode/ For example I would love to such lists, i cant make references. Thanks in advance.

• Rebooting an EC2 Instance

  - by ABrown

  I'm working on a project involving EC2 and I'm having a difficult time wrapping my head around this concept. With EC2 instances, will non-EBS backed volumes (standard EC2) survive a reboot of the OS? For example, I have an Ubuntu instance. If I type "/sbin/shutdown -r now", will I lose all data on the drive not in the AMI? I understand that if I terminate the instance via the tools or the control panel, I lose everything, but I can't find a concrete answer to the restart issue. An extra gold star goes to anyone who can link to documentation clearly explaining this. ;) Thanks for your time!

• Is it reasonable to null guard every single dereferenced pointer?

  - by evadeflow

  At a new job, I've been getting flagged in code reviews for code like this: PowerManager::PowerManager(IMsgSender* msgSender) : msgSender_(msgSender) { } void PowerManager::SignalShutdown() { msgSender_->sendMsg("shutdown()"); } I'm told that last method should read: void PowerManager::SignalShutdown() { if (msgSender_) { msgSender_->sendMsg("shutdown()"); } } i.e., I must put a NULL guard around the msgSender_ variable, even though it is a private data member. It's difficult for me to restrain myself from using expletives to describe how I feel about this piece of 'wisdom'. When I ask for an explanation, I get a litany of horror stories about how some junior programmer, some-year, got confused about how a class was supposed to work and accidentally deleted a member he shouldn't have (and set it to NULL afterwards, apparently), and things blew up in the field right after a product release, and we've "learned the hard way, trust us" that it's better to just NULL check everything. To me, this feels like cargo cult programming, plain and simple. A few well-meaning colleagues are earnestly trying to help me 'get it' and see how this will help me write more robust code, but... I can't help feeling like they're the ones who don't get it. Is it reasonable for a coding standard to require that every single pointer dereferenced in a function be checked for NULL first—even private data members? (Note: To give some context, we make a consumer electronics device, not an air traffic control system or some other 'failure-equals-people-die' product.) EDIT: In the above example, the msgSender_ collaborator isn't optional. If it's ever NULL, it indicates a bug. The only reason it is passed into the constructor is so PowerManager can be tested with a mock IMsgSender subclass.

• Missing 16:10 resolutions with Nvidia drivers (Can't add resolutions)

  - by Wuinny

  I have a laptop with a Nvidia 9650M GT and used the drivers that Seven brought me. It works fine but Metro 2033 tells me that I have to upgrade my drivers to play the game. So I did it. But since I did a clean install of the new Nvidia drivers, I just have 1440*900 or 4:3 resolutions. I usually played with 1280*800 or 1184*740 (for performance issue) With the "old" drivers I was able to create custom resolution (1184*740) in Nvidia control panel but now when I try it tells me that "my monitor cannot support this resolution". When I insist, it works but soon as I shut down my computer I have to recreate it.. Do anyone have a fix?

• Versioning files in Windows XP

  - by Mike Cole

  I would like to set up an archive folder in Windows XP that would allow me to drop several different versions of the same file, and have it store each version. I would envision this to work similar to the recycle bin, where you can drop the same file 10 times and it stores each version. Anybody know how I can do this? Thanks! Edit: Using a Version Control System is complete overkill for this situation. I may just write a script that appends a date/time stamp to the file when added to the folder.

• Do you have to recreate workspaces after upgrading a TFS 2008 server to TFS 2010?

  - by Clara Oscura

  I am just reposting this thread from a MSDN forum since it seems to be unavailable. It was very useful when I was having trouble with my folder mappings after migrating to TFS 2010. Question: I opened VS2008 and connected it to the upgraded 2010 TFS server.  Upon clicking any of our Team Projects in source control explorer I get "Team Foundation Error - The workspace MYWORKSPACE;DOMAIN\MYUsername already exists on computer MYPCNAME." Answer: The same local paths on your machine are mapped to 2 different workspaces, one on the preupgrade server and one on the postupgrade server.  It's not safe to have multiple workspaces on different servers mapped to the same local paths b/c you could pend some changes while connected to one server, and the other server would have no idea what you did.  You should either delete your conflicting workspaces from one of the servers (if you don't need them on both), or test the new TFS instance from a new workspace (on different machine). If you want to test an existing production workspace on both servers, then yes, you will have to mess around with the workspace cache. You don’t have to delete the entire cache, you just need to run "tf workspaces /remove:* /server:<serverurl>" to clear the cached workspaces from a server (the command won't delete the workspaces), and possibly "tf workspaces /server:<server>" to refresh the workspace cache for a given server.  You will also have to do back up and restore the workspace before switching servers or your local files could be inconsistent.

• $DISPLAY dependent gtk themes

  - by Vlad Seghete

  I have a computer at home that I log into remotely. The "monitor" for it is a TV, so I want gtk applications to use a large font and icon theme, which I managed to do by editing the ~/.gtkrc-2.0 file and some other similar stuff. What I want to be able to do is have a separate theme for when I'm logging in remotely. The best way to explain is that I would like my gtk theme choice to be dependent on the X display that the application is started on. For example, if I start something on :0.0 then that is the TV and I want large fonts, but if I start it on localhost:10.0 I want to use a regular size font, because it will get rendered on my laptop screen. The elegant solution would be to have some sort of IF statement in the .gtkrc-2.0 file that checks the $DISPLAY variable and behaves accordingly. The problem is I can't find any documentation on control structures in .gktrc files, or if it's even possible to do that.

• Laptop forgets second monitor when it goes to sleep

  - by al c

  I recently updated my nvidia driver... now I have to re-establish the connection to my second monitor everytime the laptop goes to sleep. When I open the NVIDIA control panel, the second monitor is listed there but the checkbox beside it has been cleared. Oddly my laptop screen is identified as display #3 and the external screen as display #4. Is there a registry key that I can clear to get them set back to #1 & #2? Will that fix the problem? Or is there a simpler solution. (It's a Dell Studio XPS laptop with GeForce 9500M running Windows Vista 64-bit) TIA Al

• Cannot start IIS on XP64 Professional

  - by headsling

  I have enabled the iis components for the first time on this machine, from control panel-add software-windows components, and rebooted. When I attempt to start the "Default Web Site" (which shows as 'Default Web Site (Stopped)' ) from inetmgr nothing happens.. no errors, nothing in the event log. Regmon and Filemon show no obvious errors. I've confirmed that nothing is running on port 80 and have tried changing the local port (8080, 8081 etc.,) with no effect. Further info -- I have removed the install, rebooted, added it back in, rebooted ... still not working. I have visual studio 2008, SQLServer 2008 installed.

• Pop current directory until specific file is found

  - by edarroyo

  I'm interested in writing a script with the following behavior: See if a file, build.xml, exists in the current directory, if so run a command supplied through arguments to the script. If not, pop the current directory and look at the parent. Go to 1. The script would end once we find the file or we reach the root. Also, once the script finishes and control comes back to the user I want the current directory to be that one where the script was initially l I'm not very familiar with shell scripting but any help/guidance will be much appreciated.

• Multi-monitor resolution and position settings lost after reboot

  - by SoftDeveloper

  I've had two 1280x1024 monitors running for years on an nVidia 8800GT card with no problems. I've now replaced one monitor with a new 2560x1440 one. The card seems to support both fine, however every time I reboot the resolutions and monitor positions revert to the old settings. I've tried upgrading, downgrading, stripping out and reinstalling many versions of the nvidia drivers to no avail. Logging in as another user doesn't help - same problem. Booting into another another OS (Win7 64) works OK, so it is just this OS installation. During boot up everything looks fine (ie native 2450x1440 res) until the nVidia control panel or something is loaded which flips it back into the old mode. I have no old saved nvidia profiles. I can't find anything in the registry relating to these old settings. Its driving me crazy having to set resolutions and realign monitors on every reboot! Can anybody help?

• How to go about designing an intermediate routing filter program to accept input and forward accordingly?

  - by phileaton

  My predicament: I designed an app, written in Python, to read my mail and check for messages that contain a certain digital signature. It opens these and looks for keywords. If the message contains these keywords, certain related functions area executed on the computer. It is a way I can control my computer from my cell phone without being there. I am still in the beginning stages and it can only currently remotely open and close applications/processes. The obvious issue is security risks. I hoped to spearhead that by requiring and checking for that digital signature. However, my issue comes when I'd like to make this program usable by multiple users. The idea is that the user will send keywords: username and password, for instance, to log into their personal email account and send messages to it to be parsed. Please ignore the security implications of sending non-encoded passwords through email. (Though if you could help me on that part I'd much appreciate it as well, but currently, that is not the scope of my question.) My issue is designing an intermediary process that will take an email/password to read an email and scan for those keywords. The issue is, that the program has to be accessing an email to read the email for the username/password! I have got myself into a loop and cannot figure out how to have this required intermediary program. I could just create an arbitrary email account and have that check for login-creds, but is there a better way of doing this than that? Also, is there a better way of communicating with a computer remotely than this? Especially if the computer is not a server and is behind a router with only a subnet ip? If I am asking this question in the wrong place, I deeply apologize. Any help would be much appreciated!

• Users can benefit from Session Tracking

  I use to work for a large Dental Plan marketing website a few years ago and they had a large customer-driven website that sold Dental Plans to consumers. Their website started tracking users as soon as they hit their web servers, and then they logged everything they could about the user. There are a lot of benefits for using session tracking for both the user and the website. Users can benefit from session tracking due to the fact that a website can retain pertaining information for the user so that they do not have to re-enter the same information repeatedly. In addition, websites can hold specific items in a cart for each user so that they can pay for all of their  items at once when they are ready to complete their purchases. Websites can also benefit from session tracking because they can determine where a specific user came from and which advertising partner gave them a sale. This information is very useful when deciding on where to spend an advertising budget. There is only one real disadvantage when it comes to session tracking, Users can not really control what is actually tracked by a website. Yes, they can disable cookies and this will help, but that means that no tracking can be done at all. Most sites require users to have cookies enabled in order for users to make purchases or login to their accounts.

• UVC device Logitech WebCam 9000 pro

  - by Pavel

  There is such a good webcam in universe that acts as a "USB Video Class" (UVC - video USB standart interface) - the logitech webcam 9000. UVC offer unified interface allowing to control it or grab a picture from it by any UVC-driver. You need one universal driver and you support all the UVC devices (webcams, video-cameras, video-grabbing-cards etc). For example, in linux - if you have UVC driver - you don't need to think about specific webcam driver for UVC webcam. UVC has unified way that webcam transmit its awailable resolutions and other capabilities, so i see 1600x1200 resolution without any problem. I wonder if windows 7 has UVC. I mean "universal UVC" (-; It says "USB Video Class", but doesn't give resolutions larger than 640x480 and webcam's controls, like 'sharpness', 'focus' and other as linux's driver does...

• External monitor on old Dell 700m?

  - by Adam Henne

  Okay, linux noob. I installed 10.04 on an old Dell 700m in hopes of using it as a media center device. That seems to work great, except now it won't output to the external monitor. VGA cable works fine, TV recognizes other computers fine, it's the laptop that won't output. Turns out that the 700m, unlike every other computer out there, doesn't have a Fn hotkey to switch monitors. The only way to do it in Windows was to go through the Control Panel. In Ubuntu, though, the Monitor setup won't detect or recognize any monitors. The laptop display works fine, but I can't adjust or add anything. I did a little research and found suggestions for older Ubuntu builds involving the xorg.conf. I tried one out, in spite of my unfamiliarity, and it's screwed the whole display big time. I can fix that with a clean reinstall, that's no problem, but I'm cautious about editing xorg again. Any suggestions? Thank you!

• How to install php cli with pnctl alongside Zend Server

  - by fazy

  I have Zend Server CE 5.6 with PHP 5.2 running on Ubuntu 11.10. Now the need has arisen to run a command line PHP script that uses PHP's pnctl functionality. First of all, I had no PHP command line in my path, so I made a symlink from the Zend one: sudo ln -s /usr/local/zend/bin/php /usr/bin However, when I run my script, I now get this error: PHP Fatal error: Call to undefined function pcntl_fork() The Zend web control panel doesn't offer pnctl in the list of modules, so how do I get this functionality? Is it safe to use apt-get to install PHP directly, to run alongside the Zend instance? If so, how do I make sure I get version 5.2? I guess the following would pull in PHP 5.3: apt-get php5-cli I could probably muddle through but any pointers to help me avoid making a mess would be much appreciated!
