• User Permissions: Daemon and User

  - by Eddie Parker

  Hello: I often run into this issue on Linux, and I'd love to know the proper way of solving it. Say I have a daemon running. In my example, I'll use LigHTTPD, a webserver. Some software, like Wordpress, enjoys having read/write access to files for updating applications via a web interface, which I think is quite handy. At the same time, I enjoy being able to hack on my files using vim, using my local user account, 'eddie'. Herein lies the rub. Either I chown everything to lighttpd or eddie and a shared group between them both, and chmod it 660, or perpetually sudo to edit the damned things. The former isn't a bad solution, until I create a new file in which case I have to remember to chmod it appropriately, or create some hack like a cron job that chmods for me. Is there an easier way of doing this? Have I overlooked something? Cheers, -e-

• Folder Redirection - Explorer requires manual refresh

  - by Pete

  Hello, I am having an issue where - when a users my documents folder is redirected to a DFS share, windows explorer requires a manual refresh after creating a new folder, file, etc. (Interestingly, not when making a new briefcase) I have tried a number of MS knowledge base articles, a hot-fix and a registry change, all with no success. (( http:// support.microsoft.com/?kbid=823291 ; http:// support.microsoft.com/kb/873392 )) The problem only occurs when going through the my documents icon. If I map a home drive for the user to the exact same location (IE - H:\DFS\user\documents) , open that drive and make new folders, then there is no problem. Mapping my documents to H:\ also resolves the issue, however, as we need folder sync and people logging on off site with cached profiles this is not a workable solution (as H: will not map and there will be no access to their docs.) Has anyone managed to figure a fix for this? Thanks, Pete.

• disable all hotkeys with dconf-editor

  - by Gijs

  I'm building a deb package that will create a kiosk user account. When you login to this account, the browser automatically starts and navigates to a pre-given website. Also all the hotkeys should be disabled except for one you defined. Now I'm at the part that the browser starts and my disable script is excecuted on logon but for exaple, I can still close the browser with Alt + F4. And when i check the dconf-editor for the hotkeys, for every single one the bind is deleted, but mine for close isn't added. Like you can see in the printscreen. I disabled all these keys with this code, one line for evere hotkey gsettings set org.gnome.desktop.wm.keybindings begin-resize [] So this seams to work, but at the bottom of my disable script this line should be executed. gsettings set org.gnome.desktop.wm.keybindings close ['<Alt>b'] Does anyone know why i'm able to unbind all these hotkeys in my dconf-editor but they are able to still do their job? And when it is possible to unbind them, why cant I bind mine? I searched the web for a solution but couldn't find one fitting my needs, I hope some of you know the answer to this. Regards Gijs

• How can I dual boot a UEFI OS and a legacy boot OS, or convert stock Windows 8 to BIOS?

  - by The Great Widi

  I have a computer (HP Pavilion g6-2342dx) which came with Windows 8, and thus the new UEFI boot system. I would like to install a few OS's which are not EFI compatible, and Arch GNU/Linux with BIOS mode. However, I would not like to completely wipe all my files to set to legacy. My preferred options would be to: 1. Multiboot legacy OS alongside my EFI os 2. Convert Windows 8 and Ubuntu to legacy without reformatting or switching to MSDOS part table. If anyone could suggest a solution or a method, your help would be appreciated! Thanks!

• How to black out second monitor when playing a full screen game?

  - by Gary

  I've got two monitors. When I play a full screen game in my primary monitor, the second monitor still shows the Windows desktop. How can I black out the second monitor so that it doesn't show anything at all? My graphics card is from ATI. I'm running Windows 7 in Boot Camp on an iMac. I don't know if this makes a difference, however, as any solution to my question will do, really. For instance, is there a tiny app that I could run to disable the second monitor for a while? I'd rather not have to open Windows display settings every time I run a game and disable the monitor that way, though.

• Dell Docking Station Doesn’t Detect USB Mouse and Keyboard

  - by Ben Griswold

  I’ve found myself in this situation with multiple Dell docking stations and multiple Dell laptops running various Windows operating systems.  I don’t know why the docking station stops recognizing my USB mouse and keyboard – it just does.  It’s black magic.  The last time around I just starting plugging the mouse and keyboard into the docked laptop directly and went about my business (as if I wasn’t completing missing out on a couple of the core benefits of using a docking station.)  I guess that’s what happens when you forget how you got yourself out of the mess the last time around.  I had been in this half-assed state for a couple of weeks now, but a coworker fortunately got themselves in and out of the same pickle this morning.  Procrastinate long enough and the solution will just come to you, right? Here’s how to get yourself out of this mess: Undock your computer Unplug your docking station Count to an arbitrary number greater than 12.  (Not sure this is really required, but…) Plug your docking station back in Redock your machine I put my machine to sleep before taking the aforementioned actions.  My coworker completely shutdown his laptop instead.  The steps worked on both of our Win 7 machines this morning and, who knows, it might just work for you too.

• Windows XP stay logged in

  - by VEC

  Is there a way to make Windows XP stay logged in even after the user logs off? Right now the PCs log in at start up and we're using WinOFF to shut down the computer after X minutes of inactivity. The problem is that WinOFF does not work when the user logs off and stays in the "Select user login" screen. I'm thinking a possible solution would be to make the computer log back in as the default user after Y minutes of inactivity. How can I make it so that Windows XP logs in automatically after the user logs off?

• Firefox does not print flash content

  - by Rochelle

  I am using Firefox 3.6.15 on a Windows 7 Professional, 64-bit Operating System, Intel Core i7 CPU, 3.33GHz, 10BG RAM, by Hewlett-Packard. Firefox does not print flash content, aka swf objects, nor does it show them in the print preview pane...I want to print out the entire web page with the flash content. I seem to only be able to see flash and html content together in print preview and to print in IE8. I have tried to google this issue, but could not find a solution. I was trying to print preview/print out the following site: http://www.discovertheponds.com/. Flash content will display in print preview and print in IE8, but neither print preview or print in Firefox. I have also updated the Java on my computer to the most recent update, and ran the firefox plug-in checker at http://www.mozilla.com/en-US/plugincheck/ . I do run Firebug and Web Developer, but have currently disabled them. Is this problem on my end, meaning some issue with my computer...or is this because of how the website was programmed in HTML/Flash...or is this a bug with Firefox? I am a website designer and am also concerned that others will not be able print sites I develop or have already developed that have flash content from Firefox. I used to think Firefox was better than IE at everything. What happened here? Was it some change in Firefox's version that caused this problem?

• Linux openSUSE 11.2 on VAIO Z890T

  - by alfredozn

  I have a VAIO Z-series (VGN-Z890T) and I want to install openSUSE 11.2. I found some guides to fix the problem for the video card switch, but all for older models, those preconfigured with windows vista. It looks like newer model use a different bios configuration to support hot swap between cards in Windows 7 and this change breaks the solution to my problem. I'm not an experienced linux user, but i was using it recently on my old computer ind definitively I want it on my laptop. I installed openSUSE once and i was trying and trying to solve it until I finished reinstall again and use a fresh installation. My question is: Does anyone has installed and configured successfully openSUSE on one of the latest vaio z laptops???

• How do you create large, growable, shared filesystems on Linux at AWS?

  - by Reece

  What are acceptable/reasonable/best ways to provide large, growable, shared storage at AWS, exposed as a single filesystem? We're currently making 1TB EBS volumes ~biweekly and NFS exporting with no_subtree_check and nohide. In this setup, distinct exports appear under a single mount on the client. This arrangement does not scale well. The options we've considered: LVM2 with ext4. resize2fs is too slow. Btrfs on Linux. not obviously ready for prime time yet. ZFS on Linux. not obviously ready for prime time yet (although LLNL uses it) ZFS on Solaris. future of this combo is uncertain (to me), and new OS in the mix glusterfs. heard mostly good but two scary (and maybe old?) stories. The ideal solution would provide sharing, a single fs view, easy expandability, snapshots, and replication. Thanks for sharing ideas and experience.

• What's the simplest way to serve RhodeCode over HTTPS on windows?

  - by Keith Nicholas

  I have RhodeCode working with http using the paster serve tool that it comes with... I'm struggling to find a "simple" solution to get this running on HTTPS. A lot of discussion is about using Apache to do this on unix. Not a lot of info on how to do it on IIS. I was looking at paster serve and it seems to be able to serve using HTTPS, but can't quite work out how to get this going. However the real goal is just to serve RhodeCode over HTTPS in the simplest way possible ( all self contained would be brilliant).

• Looking for Inneroffice Access Tool, Workstation to Workstation

  - by nicorellius

  This may be a simple question to answer, and I apologize if it's a duplicate. I looked through the suggestions and nothing jumped out at me as the right answer, so here goes: My office has several workstations, Macs and Windows boxes. We do have a firewall and a VPN solution, so getting in to the network from outside is easy. Likewise, we use GoToMeeting for demos and when we help our customers with their issues. But we have one workstation that has certain testing tools on it, and instead of walking across the office to this machine, I'd like to access it from my desk (and monitor it). I will need to open a command line and run commands. I could start a GoToMeeting and do it this way, but that seems overkill and clunky. Is there a simpler tool that allows pseudo-remote access within the same office/network for this kind of access?

• Throughput tool with decent graphing.

  - by Cory J

  I've been looking through some of the tools available for measuring network throughput, namely iperf, bwping, ttcp, etc. I am planning on doing throughput tests over a long period of time, so what I really need is good graphing output, preferably rrd graphs. The Jperf frontend for iperf will generate a graph, and bmon has a nice command-line graph, but these simply count seconds since the test was started. I am trying to measure trends in throughput over times of the day, so a graph with times and days is necessary. So a way to get iperf to log to RRDs would be best, if this isn't possible could someone point me toward another solution?

• 2D Procedural Terrain with box2d Assets

  - by Alex

  I'm making a game that invloves a tire moving through terrain that is generated randomly over 1000 points. The terrain is always a downwards incline like so: The actual box2d terrain extends one screen width behind and infront of the circular character. I'm now at a stage where I need to add gameplay elements to the terrain such as chasms or physical objects (like the demo polygon in the picture) and am not sure of the best way to structure the procedural generation of the terrain and objects. I currently have a very simple for loop like so: for(int i = 0; i < kMaxHillPoints; i++) { hillKeyPoints[i] = CGPointMake(terrainX, terrainY); if(i%50 == 0) { i += [self generateCasmAtIndex:i]; } terrainX += winsize.width/20; terrainY -= random() % ((int) winsize.height/20); } With the generateCasmAtIndex function add points to the hillKeyPoints array and incrementing the for loop by the required amount. If I want to generate box2d objects as well for specific terrain elements, I'll also have to keep track of the current position of the player and have some sort of array of box2d objects that need to be created at certain locations. I am not sure of an efficient way to accomplish this procedural generation of terrain elements with accompanying box2d objects. My thoughts are: 1) Have many functions for each terrain element (chasm, jump etc.) which add elements to be drawn to an array that is check on each game step - similar to what I've shown above. 2) Create an array of terrain element objects that string together and are looped over to create the terrain and generate the box2d objects. Each object would hold an array of points to be drawn and and array of accompanying box2d objects. Any help on this is much appreciated as I cannot see a 'clean' solution.

• Why Oracle Delivers More Value than IBM in Data Integration Solutions

  - by irem.radzik(at)oracle.com

  For data integration projects, IT organization look for a robust but an easy-to-use solution, which simplifies enterprise data architecture while providing exceptional value-- not one that adds complexity and costs. This is a major challenge today for customers who are using IBM InfoSphere products like DataStage or Change Data Capture. Whereas, Oracle consistently delivers higher level value with its data integration products such as Oracle Data Integrator, Oracle GoldenGate. There are many differentiators for Oracle's Data Integration offering in comparison to IBM. Here are the top five: Lower cost of ownership Higher performance in both real-time and bulk data movement Ease of use and flexibility Reliability Complete, Open, and Integrated Middleware Offering Architectural differences between products contribute a great deal to these differences. First of all, Oracle's ETL architecture does not require a middle-tier transformation server, something IBM does require. Not only it costs more to manage an additional transformation server including energy costs, but it adds a performance bottleneck as well. In addition, IBM's data integration products are complex and often require lengthy professional services engagements to integrate. This translates to higher costs and delayed time to market. Then there's the reliability factor. Our customers choose Oracle GoldenGate over IBM's InfoSphere Change Data Capture product because Oracle GoldenGate is designed for mission-critical systems that require guaranteed data delivery and automatic recovery in case of process interruptions. On Thursday we will discuss these key differentiators in detail and provide customer examples that chose Oracle over IBM in data integration projects. Join us on Thursday Feb 10th at 11am PT to learn how Oracle delivers more value than IBM in data integration solutions.

• Linux software to maintain old/backup versions of directory tree

  - by Bittrance

  I am replacing an old Linux file server serving NFS and CIFS. For the new server (still serving CIFS and NFS), I would like to have software that automatically and efficiently maintains old revisions of files in parallel trees, so that they can be accessed by users without special tools. I am looking for software that is akin to Time Machine or Flyback, but works well on a server. The dataset is some 10000 files weighing maybe 60 GB. Changes are relatively few, usually less than 100 files changes daily. Using LVM snapshots will not cut it, as the old revisions must reside on a separate set of disks from the live data. Edit: To clarify: keeping old revisions is non-vital addition to the solution, so any suggestion will have to stay in the range of some hundred euros.

• Out of sync audio / video on Hackintosh

  - by user22902

  I have a PC with OSx86 (10.6.2) on it. Under Leopard my videos worked great, but now with VLC the audio is all garbled and video is way too fast. In Quicktime X video is too fast. MPlayer OSX Extended plays videos fine, but doesn't support many codecs. I have a Geforce 9800 GTX with qe ci ocl... If theres no solution, then are there any other players for OS X that support a lot of codecs? I don't like Windows so that's not an option. Thanks

• Using Scrum on small projects where Owner doesn't want to be involved

  - by Andrej Mohar

  Recently I've been reading and learning quite a lot about scrum and I like it a lot. However, I do have a couple of likely scenarios in my head to which I don't know the solution. So let's say that I might want to organize an agile team of (for instance) four web developers (one of them UI/UX designer). This team would operate on scrum principles. Initially we would probably be working on projects like landing pages for ordinary people's small businesses, like renting apartments, selling cookies... Such customers simply can't be set with Product Owner role (IMHO), because they usually expect to hire a company, give them the overall project goal with some details, and then expect the job to be done (including a lot of decision making) with as little of their involvement as possible (in their opinion, they have more important things to do). Let's say I'd like to engage myself in a developer/scrum master role (I know that even that is debatable, being a team member and scrum master at once), so I simply shouldn't take the role of the product owner as well. So as for my questions: If I'm my company's business owner, do I simply need to be a product owner as well (do these roles include each other)? Can I employ a sales person which might have the product owner role? Would it be better if it is an experienced developer instead of a sales person? Is this even a smart move? Lastly, is there another agile approach that might better suit my position? EDIT: Thank you everyone for good inputs. I added some comments, any aditional info will be greatly appreciated.

• What are the benefits of full VDI over Remote Desktop Services?

  - by Doug Chase

  We're talking about piloting VDI here, but the more research I do, the more it seems like it would make more sense just to upgrade and expand our TS (RDS) environment. I feel like you can pull off more sessions per core on RDS than on any VDI solution I've looked at. Is this the case? Is there a decision matrix anywhere describing the benefits of using full virtualized desktops over using a remote desktop farm? We need good video performance for clinical imaging - will this work better on one infrastructure or the other? (Does this question have a specific enough answer for it to be on SF? Regardless, I feel like having this here will be helpful for someone in the future...)

• How to create Isolated test environment

  - by Safin09

  Hi All, I am very new to the VMware world. We have VMWare vCenter 4 in the production environment but we have created multiple VLAN through Cisco Switch. I want know, how I can create an isolated test environment for software testing purpose only, so anything will happen in that test vLan will not make trouble in the production environment. "Host-only networking" is the solution or there is a better way to achieve this result? My requirements A. Hosts should be able to access Internet and a Network Share drive but not Production network B. Hosts should connect each other inside the Virtual LAN C. I should be able to take automatic or periodic backup or snapshoot and deploy snapshot when necessary. Whatever your answer is, please give me steps, how to do, if possible. If I need to purchase anything, I am ready to do but I don't want to spend big money. Many thanks in advance.

• Wordpress site on EC2 instance suddenly superslow

  - by Emil

  Set up a wordpress page the other day following this guide. The site was up and running, loading quickly and all was well, until today. Suddenly, loading the site takes forever and doesn't even work properly, the page shows up in an incomplete fashion. I tried rebooting the instance but that didn't help. The only actions I've taken on the server is to create an elastic IP, and to point a domainname to that IP. But I don't see how that could've slowed down the page. Any thoughts on what could have caused this and on a solution to the problem?

• Is it Secure to Grant Apachie User Ownership of Directories & Files for Wordpress

  - by Oudin

  I'm currently setting up WordPress on an Ubuntu server 12 everything runs fine but there is an issue when it comes to automatically updating and uploading media via WP as Apache "www-data" user does not have permissions to write to the directories. "user1" has full permission All my directories have permissions of 0755 and files 644 my directories setup is as follows: /home/user1/public_html All WP files and directories are in "public_html" In order to work around the auto updating and uploading media I've granted Apache user ownership to the following directories sudo chown www-data:www-data wp-content -R sudo chown www-data:www-data wp-includes -R sudo chown www-data:www-data wp-admin -R I would like to know security wise how secure this is and if it is not secure what would be the best solution? That will allow me to keep all files and directories owned by user1 and still allow wp to be able to automatically update and uploading media

• Use external speakers with laptop hooked to separate monitor?

  - by lhan16

  I have a laptop with a set of external speakers hooked up to it on my computer desk. The speakers use the standard 3.5mm audio (headphones) jack. The speakers work fine, but I've recently added a separate monitor to my laptop via HDMI. With the monitor hooked up to my laptop and the speakers still hooked up to the laptop, sound will only come out of the built-in monitor speakers. When I look at my audio settings, there are three different "audio playback devices" showing up, but only the built-in monitor speakers make noise when I click "test" (and I hear nothing when I set any of the other devices as the default. Does anyone know how I can still use my external speakers when using a separate monitor with my laptop? I'm hoping there is a solution that doesn't require the laptop to be open or closed, because I use both scenarios. I came across this post, but it doesn't look like they had much luck.
