• Website deployment - managing uploaded content?

  - by Legion

  I'm a programmer by trade, "server administrator" by company necessity. We're looking at dumping the old painful "update site by FTP upload" style of deployment. Having the webserver check out the latest code base from version control into a folder and having a "current" symlink point to the latest checkout (allowing for easily stepping back to an older version by changing the symlink) seems to be the way we want to go. But I have a question: what's a good practice for dealing with user-uploaded content? This stuff isn't in version control. I have a couple of ideas for dealing with this, but what is the smart, accepted practice?

• X11Forwarding on MacOSX (Leopard/Snow Leopard)

  - by Shyam

  Hi, I have some remote boxes, which are a bunch of Mac Mini's. I access them now through SSH, and it fits my needs to do the maintenance. In the past, I used X11Forwarding with Linux boxes, when I was still using Debian myself, and I was able to run a specific application as if it was natively present (Firefox). I haven't succeeded to do this yet, but I assume because of the BSD underneath the fancy Apple GUI should be able to do such a task similar. I am aware of the remote administration, but I rather keep access limited to SSH on these boxes for inbound connections. Background information about the why's, tips, advice and comments are all helpful! Thanks!

• Problems while applying an svn patch to a mercurial repository

  - by user26453

  Patch file is made with TopirtiseSVN - Create Patch... Attempting to import patch into the mercurial repository using hg import patchfile. The problem I'm running into is that there seems to be problems with how hg looks for files referenced in the patch file: unable to find 'gui/gui/RemoteFramework.cpp' for patching 2 out of 2 hunks FAILED -- saving rejects to file gui/gui/RemoteFramwork.cpp.rej Seems to be an issue of where the patch was made in terms of directories and where it should be applied. Have tried playing with the --base option for hg import, but haven't gotten anywhere just yet. Anyone have any tips?

• If two separate PATH directories contain a same-named executable, how does Windows choose?

  - by Coldblackice

  I'm in the process of upgrading PEAR (PHP) on my system. The upgrade script is encouraging me to add "..\PHP\PEAR" to my PATH so that I can use "pear.bat". However, I already am able to use pear.bat. Looking in my PATH, I see that I don't have any PEAR directories, only my PHP directory. Opening my PHP directory, I see that there's a "pear.bat" in the base. But there's also a pear.bat in the PEAR subfolder of PHP. I'm wondering if I borked a PEAR install. I digress. So if I leave ..\PHP in my path, but also add ..\PHP\PEAR -- both of which have a "pear.bat" in them -- which one will Windows "choose"? How does Windows decide?

• Timesync on HyperV with CentOS 6.2

  - by WaldenL

  I've got a CentOS VM (release 6.2) running under HyperV. I have integration services installed (part of base now), and CentOS shows the current clocksource is hyperv_clocksource, however my time in the VM is about 10 minutes fast after a week of uptime. My understanding of the new IC and plugable clocksource is that this shouldn't happen any more. Is there any additional configuration necessary to get the plugable clocksource to "work?" I know there are plenty of links about setting kernel options to PIT and various stuff like that, but those all seem to pre-date the integrated clocksource support, and as I understand it shouldn't be needed anylonger. Nor should ntpd nor adjtimex.

• SRSS Client Print Module must be downloaded every use

  - by Jmcgee73

  I am currently having an issue with SQL Server Reporting Services. Everytime a user clicks the print button for the report, the user must install the ActiveX client print module. The issue is that our clients are not admins on their computers. So therefore they can not install the module. I have gotten around this roughly by adding the SQL address to trust sites, setting "Download signed Active Controls" to enable, and then giving the users permission to write to "C:\Windows\Downloaded Program Files". However, this is fix is not easy to distrubute to our user base. I am using SQL Server 2008 SP3 CU3 running on Server 2008 R2. I believe the browser thinks the version is newer than what is on the server. I have tried downloading the print module CAB file from the SQL server and installing manually. That did not work either. Thanks!

• Debugging problems in Visual Studio 2005 - No source code available for the current location

  - by espais

  Hi all I've searched up and down Google for others with a similar problem, and while I can find the error I don't think that other people have the same base problem that I do. Basically, I had to create a project for a unit-testing environment in order to run this test suite. First, I add my original C file, compile, and then a test file (C++) is generated. I then exclude my original source from the project, include this test script (which includes the original source at the top), and then run. I can debug the test file fine, but when it jumps to the original C file I get the dreaded 'no source code available for the current location' error. Both files are located within the same location, and I compiled the original file without any issue. Anybody have any thoughts about this? Its driving me crazy!

• salted passwords confusion

  - by Vasiliy Stavenko

  I'm setting up email server for the first time and confused with strange thing. I have several user accounts which stored in previous server. Passwords for this accounts are in plain text. But I want to create crypts for them. Mysql (where my users will be stored) have function encrypt(passwd, salt). If no salt given used random value. I discovered that courier uses one certain salt and crypted all passwords with it. So the task done. But I'd like to know if there's a way to define my own salt for my pop3 server?

• Single sign-on for SharePoint to MySite?

  - by Chris W

  I've got a fairly simple SharePoint 2010 farm set up: 2 WFE servers with Network Load Balancing hosting the main portal site. As per Microsoft's best practice recommendations I've set up My Sites in a separate web application. As some of the user base are not using domain joined PCs they have to login once for the portal (http://portal) and then again when the access My Sites since they're crossing in to a separate web application on a separate host (http://mysite). Portal & MySite are both hosted on the same physical WFE servers. Is there an easy way to set up some thing to stop this happening and just have them login once? I understand that there's plans for us to deploy ISA in the not too distant future - could we use ISA to manage authentication to the two sites so that the users only need to log in once?

• Perl program not getting executed in xampp

  - by user1867151

  I am very new to CGI programming in Perl. In order to learn it i installed xampp 2 days back. But I am unable to execute my perl code . The code goes as folows: #!/usr/bin/perl use CGI; $co = new CGI; print $co->header, $co->start_html(title=>'CGI Example'), $co->center($co->hi('Subhayan welcome to CGI')), $co->end_html; Have saved the code in a text file named : Subhayan1.cgi and kept it in the folder cgi-bin under xampp folder in C drive. When i try to execute this through my web browser typing : "http://localhost/cgi-bin/Subhayan1.cgi" it comes up with a "Object not found page". I checked the apache configuration file under : xampp/apache/conf/httpd.conf. I checked the entry : ScriptAlias /cgi-bin/ "C:/xampp/cgi-bin/" It looks like pointing to the correct directory. What is the issue here can anyone help please???

• Computer Studdering When Transferring Over Network

  - by Nalandial

  This is a really weird problem that I've never even seen before. When I copy to or from my server share, my computer studders terribly and the data transfers very slowly at only around 12MB/s. By studdering I mean the mouse skips around and all my applications respond very slowly; as soon as I cancel the transfer it resolves immediately. I looked at Task Manager and the CPU is only at ~35% with plenty of RAM free. This only started semi-recently; before, I had no problems and the transfer speed maxed out the gigabit connection. I have two hard drives in my computer. When I try transferring files between drives it's fine, but when I copy from the share to either drive or to it from either drive, I get studdering. I'm running Windows 7 x64. Anyone have any idea what's going on? Any help would be much appreciated.

• Keyboard not detected when trying to install Ubuntu 10.10

  - by A-ha

  I tried to install Ubuntu 10.10 desktop edition on my laptop and unfortunately it didn't detect my keyboard (it detects my mouse) so I couldn't finish installation. Is it something wrong I'm doing? There isn't really much to specify during the installation process and I'm really disappointed that such a trivial task as installation cannot be done without asking a question on a forum. Maybe it's because I'm trying to install it on my laptop? Shall I the download the notebook edition? That sound silly to me.

• How to get Windows Server 2008 VM to use multiple cores

  - by David Fraser

  I have a Windows Server 2008 machine running in VirtualBox. On initial installation, only one processor was made available, but now I want to run it as a multiprocessor machine. I have made all four cores available in the VirtualBox settings (as well as enabling VT-x/AMD-V and Nested Paging), but Task Manager still only shows one CPU. However, the four CPU cores are visible in Device Manager under Processors. In the event log on startup, I can see the following relevant events: EventLog.6009 Microsoft (R) Windows (R) 6.00.6002 Service Pack 2 Multiprocessor Free Kernel-Processor-Power.4 Processor 0 exposes the following: 1 idle state(s), 0 performance state(s), 0 throttle state(s) Kernel-Processor-Power.4 Processor 255 exposes the following: 0 idle state(s), 0 performance state(s), 0 throttle state(s) Kernel-Processor-Power.4 Processor 255 exposes the following: 0 idle state(s), 0 performance state(s), 0 throttle state(s) Kernel-Processor-Power.4 Processor 255 exposes the following: 0 idle state(s), 0 performance state(s), 0 throttle state(s) How can I make this system actually boot up as a multiprocessor machine?

• Visible Keylogger (ie not evil)

  - by Ben Haley

  I want keylogging software on my laptop for lifelogging purposes. But the software I can find is targeted towards stealth activity. Can anyone recommend a keylogging software targeted towards personal backup. Ideal Functionality Runs publicly (like in the task bar). Easy to turn off (via keyboard shortcut is best... at least via button click) Encrypted log Fast Free Cross platform ( windows at least ) The best I have found is pykeylogger which does not attempt to be stealthy, but does not attempt to be visible either. I want a keylogger focused on transparency, speed, and security so I can safely record myself. *note: Christian has a similar question with a different emphasis

• How can I create persistent SSH connection to "stream" commands over a period of time?

  - by Darth

  Say that I have an application running on one PC that is sending commands via SSH to another PC on the network (both machines running Linux). For example every time something happens on #1, I want to run a task on #2. In this setup, I have to create SSH connection on every single command. Is there any simple way to do this with basic unix tools without programming custom client/server application? Basically all I want is to establish a connection over SSH and then send one command after another.

• Create 301 Redirection in Amazon Route 53 for Wildcard Subdomains

  - by Eric Yin

  My domain name hosted on Route 53 DNS. Amazon has a guide to do 301 redirection for www. To naked domain by point www. version to a S3 static website with 301 setted up. My question is, how can I have *.domain.com all have 301 redirec to naked domain name. I guess either: Some way to get all wildcard subdomains end up into one S3 bucket, how? Or: Use CloudFront on the www. version S3 site and put wildcard subdomains on the CloudFront, but how? Or: There's some hidden settings just lies on Router 53, then where? Or: use EC2, better not suggest me this, too costing for this task. Please advice.

• Windows XP waits for usb drive on almost every operation.

  - by Tomasz Kowalczyk

  Hello everyone, I have a problem with my Windows XP operating system, particularly with the USB device that is plugged in - 1TB WD My Book external drive. I haven't found any information about such behaviour when searching in Internet, so I have to ask You. The problem is: when I am using computer, especially during work (programming), when I try to access any information on a hard disk ("internal" one), Windows seems to "consult" it with the external drive. For example, when I open file selection dialog window, if I try to change directory, system activates external drive, reads something (I hear the disk's operational noise) and after some seconds of such pause it makes the operations I requested. There are many situations in which I can reproduce this behavior - opening My Computer, shutting down system, opening partition folder from My Computer - every operation involves the usage of external drive. Please understand me properly - this is not something that happens EVERY time, but at least "many" times a day. What causes such behavior and how can I "turn off" external drive when it's not needed? Thanks in advance for your answers.

• How do I delete a differential backup?

  - by BlueMonkMN

  I often like to create backups when testing the software I work on, and will sometimes create a differential backup if I want to be able to get back to multiple previous states. However, sometimes I realize that I forgot one thing I wanted to include in a differential backup, or I no longer need a previous differential backup. Sometimes I simply want to create a new scenario from the original base image and start working with a new series of differential backups. So I'd like to be able to delete some older differential backups so I don't get confused about which ones I'm using. But I can't find any way to delete just the differential backups, selectively or all at once.

• Which tool do you use for tracking daily/weekly progress on your long-term goals?

  - by NoCatharsis

  I read through this post and this post to get an idea of short-term task management applications out there. However, now I'm having a problem tracking my longer-term goals pertaining to things like career, education, and exercise. I just discovered Disciplanner which might meet my needs but haven't had time to set it up just yet. Not to mention, it took me about 2 weeks of playing with every online to-do list app I could find before I came to a decision on which to use. I'm very particular about my tasks and goal-setting, so I would prefer to get some advice from other superusers before diving into the web again to find another life-management website.

• differencing disk opinions

  - by troth

  I've read about the performance issues with dfferencing disks but I still think there is a solid place for them and thats the os boot partition. If I'm going to have 20 vms on a csv based volume I don't won't to waste the 20+ gigs per guest just for the os boot. If I get a good base disk with all of the most used applications installed and have the pagefile located somewhere else I don't think the delta's would be that great thus it should not create a performance issue. Also in a SAN based csv volumes does it make any sense in having the pagefile go to a seperate csv volume? Any opinions on this? thanks

• sending mail using mutt + emacs

  - by lakshmipathi

  How to sent mail from emacs? I have add from address and subject and trapped inside emacs I found this There are two ways to send the message. C-c C-s (mail-send) sends the message and marks the mail buffer unmodified, but leaves that buffer selected so that you can modify the message (perhaps with new recipients) and send it again. C-c C-c (mail-send-and-exit) sends and then deletes the window or switches to another buffer But both ( ctrl+c ctrl+s ) and (ctrl-c crtl+c) are not working ps:Thought it's not programming related. it's programmer environment related question-hoping it won't be closed :)

I've activate my screen sharing on my Mac OS X and I can use another Macbook to access it no problem but once I use TightVNC or UltraVNC and any VNC base program non of them really worked for me. So is there any alternative to VNC to give me option to access my Mac using VNC or something like that? Thanks.

• Software for formatting / web-publishing tutorial-type, technical articles

  - by gojira

  I want to put some of my own technical writing on the web: tutorials, how-to's, conceptual articles about programming etc. I write mostly for myself yet, but think others can benefit from it so I want to put it online, and I also have plans of making everything more coherent and turning it into a book. My articles are not meant as a blog, they're just meant as a collection of tutorials and how-to's, but I think a blog-type software would probably be the most appropriate mode of formatting that kind of stuff. Right now I am using the blog feature of cite u like, which is very low tech and I really need something better. On my wish list is, among other things: code snippets in scrollable boxes syntax highlighting for source code snippets tagging articles with graphical icons according to topic, like in slashdot of course users (i.e. readers) should be able to comment on articles Also, just more options than a super-simple blog should look slick! should not look wikipedia-like Is there any software you can recommend for this purpose?

• Automatic LaTex document generation from Excel spreadsheet

  - by Bowler

  I have some data in an excel file from which I have to generate a report. I repeat this task fairly regularly and am looking to automate it. I have a LaTeX project into which I usually just copy data by hand, export the necessary worksheets as pdfs and add them to my LaTeX project and compile with pdflatex. It has occured to me that there must be a way to automate this process. Is there an efficient way to export the data from excel and into a LaTeX project, possibly a vba script in excel could run the process? Also, it doesn't have to be LaTeX, I'm not all that experienced with MS office's more advanced features is there some way akin to a mail merge that I could achieve this with? In some ways this might be better in case I have to pass the work on to someone who doesn't know LaTeX. Thanks.
