• From which plex am I booted from on raid?

  - by rumburak

  I have a server with mirrored boot volume. It is software raid 1 in Windows Server 2008 R2. I do not have physical access to the server. I am looking for a way to check which disk is a boot drive. I need a way to check it from os. How can I do that ? EDIT: I know how to do that, but I dont think its proper way. From diskpart I can break mirror: select volume 0 break disk=0 And Windows will only allow me to do that on not current boot disk. I want to check which one is boot without breaking mirroring.

• nautilus crash when merging/overwriting files

  - by sBlatt

  On my Ubuntu 10.10, whenever I want to copy some files/folders over some other files/folders, or when I try to empty the trash, nautilus crashes! Example: I have a folder with some files. Now I want to overwrite this folder with a folder with the same name, same files, but some additional files, the merge window comes up, I choose merge and nautilus crashes (does not respond, when I press the close button I can force close it). Some times it even does the copying/emptying (trash), but it always crashes! This happens when copying to the same partition/ntfs partition/netshares, but not when I make a new folder and copy the files/folders into that (without overwriting anything). On a netshare, it's even possible to merge these files afterwards with another computer! dmesg/syslog/messages does not show any entry related to that problem. Does anyone have a solution for this very annoying problem? EDIT: dpkg -l nautilus* (see output in pastebin) EDIT2: I found out, nautilus already crashes before clicking replace/merge (as soon as the question appeares. In the video it's not entirely clear, that i click the cross before the force-close dialog appeares. Video of problem nautilus-debug-log.txt EDIT3: Filed bugreport: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/678233

• dynamic 2d texture creation in unity from script

  - by gman

  I'm coming from HTML5 and I'm used to having the 2D Canvas API I can use to generate textures. Is there anything similar in Unity3D? For example, let's say at runtime I want to render a circle, put 3 initials in the middle and then take the result and put that in a texture. In HTML5 I'd do this var initials = "GAT"; var textureWidth = 256; var textureHeight = 256; // create a canvas var c = document.createElement("canvas"); c.width = textureWidth; c.height = textureHeight; var ctx = c.getContext("2d"); // Set the origin to the center of the canvas ctx.translate(textureWidth / 2, textureHeight / 2); // Draw a yellow circle ctx.fillStyle = "rgb(255,255,0)"; // yellow ctx.beginPath(); var radius = (Math.min(textureWidth, textureHeight) - 2) / 2; ctx.arc(0, 0, radius, 0, Math.PI * 2, true); ctx.fill(); // Draw some black initials in the middle. ctx.fillStyle = "rgb(0,0,0)"; ctx.font = "60pt Arial"; ctx.textAlign = "center"; ctx.fillText(initials, 0, 30); // now I can make a texture from that var tex = gl.createTexture(); gl.bindTexture(gl.TEXTURE_2D, tex); gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, gl.UNSIGNED_BYTE, c); gl.generateMipmap(gl.TEXTURE_2D); I know I can edit individual pixels in a Unity texture but is there any higher level API for drawing to texture in unity?

• Sharing folders with VirtualBox, Win7 Host and Ubuntu 9.10 Guest

  - by unknown (google)

  I have a development setup from this tutorial: http://www.sitepoint.com/blogs/2009/10/27/build-your-own-dev-server-with-virtualbox/ But what I can't figure out is how to share a folder on my Ubuntu virtualized machine with the host Win7. I want to use a Windows text editor to edit code that's on my Ubuntu server. I've tried using the Shared Folders setting, adding "/var/www" but it says that the path is not absolute. When I click on "other", it only allows me to browse folders on my Win7 host. Both the host and guest are 64-bit OS. Thanks in advance!

• Laptop charger disconnects and reconnects, charger or battery broken?

  - by Rob

  I've got an Acer Aspire One netbook (AOA-150) and there's obviously something wrong with it. The charging port gets VERY HOT and the charger seems to disconnect and reconnect quickly sometimes. This only happens when the netbook is running, and it doesn't seem to care what it's doing other than being on. The battery has an extremely short life (< 30minutes, sometimes) and I almost exclusively run it on the power cable (which needs the battery plugged in. Having it just plugged into the wall won't start up). Does this sound like a problem with the power cable or the battery? The plug for the cable and the port get so hot that if I held them for longer than a few seconds, I'm sure I'd get burnt. EDIT Just got "Popular Question" on this and it WAS the power jack. The ground on it came loose from the board. A bit of solder on it and everything is working great again.

• Google Chrome suspicious connections

  - by Poni

  I'm using Chrome at Windows and with TCPView (of the SysInternals freeware suit) I see that chrome.exe establish connections to these IPs: 173.194.37.104 209.85.146.138 Using http://www.ipaddresslocation.org/ I check about these IPs and see they're related to Google. Now, in order to clarify, these are the exact things I do: Open up chrome, the default page is set to BLANK (i.e no homepage whatsoever). Then I get into my website which has a blank page, so no "other" http requests are made. Right from this point there is a persistent connection, usually to '173.194.37.104'. What are these?? Very suspicious.. Edit #1: - I'm in 'incognito' mode right from start, when launching Chrome, using a shortcut with the '-incognito' switch. - I've turned off all phishing protections and other "advance" features in order to reduce Chrome's network activity.

• On WHM/cPanel how can you tell which packages are in use?

  - by Paul Masri

  I want to find out a) which packages are currently in use, and b) which accounts are using them, so I can do some housekeeping. If I go to 'Show Reseller Accounts', it'll list all the accounts by reseller and I can see which accounts use which, so I could go the longhand route of counting through them one by one, but I wondered if there's a way of getting a simple listing. NB: I've seen that if I go to 'Edit Reseller privileges & nameservers' for one of my resellers, I'll see a 'Package limits' table which has a 'Current' column that shows exactly what I'm looking for... but it's for that reseller only, and I don't get this table for resellers that have no package limits (e.g. me).

• What are the hard and fast rules for Cache Control?

  - by Metalshark

  Confession: sites I maintain have different rules for Cache Control mostly based on the default configuration of the server followed up with recommendations from the Page Speed & Y-Slow Firefox plug-ins and the Network Resources view in Google's Speed Tracer. Cache-Control is set to private/public depending on what they say to do, ETag's/Last-Modified headers are only tinkered with if Y-Slow suggests there is something wrong and Vary-Accept-Encoding seems necessary when manually gziping files for Amazon CloudFront. When reading through the material on the different options and what they do there seems to be conflicting information, rules for broken proxies and cargo cult configurations. Any of the official information provided by the analysis tools mentioned above is quite inaccessible as it deals with each topic individually instead of as a unified strategy (so there is no cross-referencing of techniques). For example, it seems to make no sense that the speed analysis tools rate a site with ETag's the same as a site without them if they are meant to help with caching. What are the hard and fast rules for a platform agnostic Cache Control strategy? EDIT: A link through Jeff Atwood's article explains Caching in superb depth. For the record though here are the hard and fast rules: If the file is Compressed using GZIP, etc - use "cache-control: private" as a proxy may return the compressed version to a client that does not support it (the browser cache will hold files marked this way though). Also remember to include a "Vary: Accept-Encoding" to say that it is compressible. Use Last-Modified in conjunction with ETag - belt and braces usage provides both validators, whilst ETag is based on file contents instead of modification time alone, using both covers all bases. NOTE: AOL's PageTest has a carte blanche approach against ETags for some reason. If you are using Apache on more than one server to host the same content then remove the implicitly declared inode from ETags by excluding it from the FileETag directive (i.e. "FileETag MTime Size") unless you are genuinely using the same live filesystem. Use "cache-control: public" wherever you can - this means that proxy servers (and the browser cache) will return your content even if the rest of the page needs HTTP authentication, etc.

• Compressing 2D level data

  - by Lucius

  So, I'm developing a 2D, tile based game and a map maker thingy - all in Java. The problem is that recently I've been having some memory issues when about 4 maps are loaded. Each one of these maps are composed of 128x128 tiles and have 4 layers (for details and stuff). I already spent a good amount of time searching for solutions and the best thing I found was run-length enconding (RLE). It seems easy enough to use with static data, but is there a way to use it with data that is constantly changing, without a big drop in performance? In my maps, supposing I'm compressing the columns, I would have 128 rows, each with some amount of data (hopefully less than it would be without RLE). Whenever I change a tile, that whole row would have to be checked and I'm affraid that would slow down too much the production (and I'm in a somewhat tight schedule). Well, worst case scenario I work on each map individually, and save them using RLE, but it would be really nice if I could avoind that. EDIT: What I'm currently using to store the data for the tiles is a 2D array of HashMaps that use the layer as key and store the id of the tile in that position - like this: private HashMap< Integer, Integer [][]

• When browsing a specific network share remotely, Windows Explorer continuously jumps back to the parent folder

  - by Evil Pigeon

  I am accessing a specific network path on another domain. It looks something like this: \\CoputerName.OtherDomain.in\c$\Inetpub\Testing\Website\ In under 30 seconds, I am automatically jumped back to \\CoputerName.OtherDomain.in\c$\Inetpub\Testing\ In less time it then jumps back to \\CoputerName.OtherDomain.in\c$\Inetpub\ Then it jumps back to c$ for its final resting place. \\CoputerName.OtherDomain.in\c$\ At first I thought this had to with a faulty keyboard, but this behaviour also occurs when the window does not have focus. It's as if windows thinks that the folder no longer exists (as in someone else has deleted or moved it). This behaviour is not specific to my PC either, it occurs from other machines in the office. Edit: It looks like this issue only occurs from other Windows 7 machines. There are no issues accessing the path from XP.

• How secure is a bluetooth keyboard against password sniffing?

  - by jhs

  In a situation where an admin will enter sensitive information into a keyboard (the root password), what is the risk that a bluetooth keyboard (ship by default with Mac systems these days) would put those passwords at risk? Another way of asking would be: what security and encryption protocols are used, if any, to establish a bluetooth connection between a keyboard and host system? Edit: Final Summary All answers are excellent. I accepted that which links to the most directly applicable information however I also encourage you to read Nathan Adams's response and discussion about security trade-offs.

• Why would a FaceBook application "work" on a profile, but not a page?

  - by edt

  I made a FaceBook application that works fine on profiles, but I can't figure out how to get it to show on a FaceBook page. For example, after I visit the application canvas URL, allow the application, then edit application settings and "add" to box and tab view... I cannot click the "plus" symbol to the left of the tabs in order to add a tab for the application. It does not appear in the list of available applications. Meanwhile, the application is working/showing up on profiles with no issues. I DID check the "Installable to Pages" checkbox on the application (authentication tab) settings. What could cause this? Here is the application canvas URL: http://apps.facebook.com/russian_girls/

• Give a session on C++ AMP – here is how

  - by Daniel Moth

  Ever since presenting on C++ AMP at the AMD Fusion conference in June, then the Gamefest conference in August, and the BUILD conference in September, I've had numerous requests about my material from folks that want to re-deliver the same session. The C++ AMP session I put together has evolved over the 3 presentations to its final form that I used at BUILD, so that is the one I recommend you base yours on. Please get the slides and the recording from channel9 (I'll refer to slide numbers below). This is how I've been presenting the C++ AMP session: Context (slide 3, 04:18-08:18) Start with a demo, on my dual-GPU machine. I've been using the N-Body sample (for VS 11 Developer Preview). (slide 4) Use an nvidia slide that has additional examples of performance improvements that customers enjoy with heterogeneous computing. (slide 5) Talk a bit about the differences today between CPU and GPU hardware, leading to the fact that these will continue to co-exist and that GPUs are great for data parallel algorithms, but not much else today. One is a jack of all trades and the other is a number cruncher. (slide 6) Use the APU example from amd, as one indication that the hardware space is still in motion, emphasizing that the C++ AMP solution is a data parallel API, not a GPU API. It has a future proof design for hardware we have yet to see. (slide 7) Provide more meta-data, as blogged about when I first introduced C++ AMP. Code (slide 9-11) Introduce C++ AMP coding with a simplistic array-addition algorithm – the slides speak for themselves. (slide 12-13) index<N>, extent<N>, and grid<N>. (Slide 14-16) array<T,N>, array_view<T,N> and comparison between them. (Slide 17) parallel_for_each. (slide 18, 21) restrict. (slide 19-20) actual restrictions of restrict(direct3d) – the slides speak for themselves. (slide 22) bring it altogether with a matrix multiplication example. (slide 23-24) accelerator, and accelerator_view. (slide 26-29) Introduce tiling incl. tiled matrix multiplication [tiling probably deserves a whole session instead of 6 minutes!]. IDE (slide 34,37) Briefly touch on the concurrency visualizer. It supports GPU profiling, but enhancements specific to C++ AMP we hope will come at the Beta timeframe, which is when I'll be spending more time talking about it. (slide 35-36, 51:54-59:16) Demonstrate the GPU debugging experience in VS 11. Summary (slide 39) Re-iterate some of the points of slide 7, and add the point that the C++ AMP spec will be open for other compiler vendors to implement, even on other platforms (in fact, Microsoft is actively working on that). (slide 40) Links to content – see slide – including where all your questions should go: http://social.msdn.microsoft.com/Forums/en/parallelcppnative/threads.   "But I don't have time for a full blown session, I only need 2 (or just 1, or 3) C++ AMP slides to use in my session on related topic X" If all you want is a small number of slides, you can take some from the session above and customize them. But because I am so nice, I have created some slides for you, including talking points in the notes section. Download them here. Comments about this post by Daniel Moth welcome at the original blog.

• How to set global PATH on OS X Server 10.6.6?

  - by Adam Lindberg

  I'm running Tomcat on OS X Server 10.6.6 under the normal Web component that comes with the OS. This has worked fine so far, but I need to add some entries to the $PATH environment variable for programs that I want access to from the web server (more specifically, I'm running Hudson under Tomcat which needs access to build tools that I have installed). Tomcat and the Web component seems to run under the user _appserver which has a different $PATH than the administrator account. What's the proper way to add a global entry to the $PATH in OS X Server for the Web component? Preferable it should be done only once so that both the _appserver and Administrator user can access the same $PATH. EDIT: Adding the path to /etc/paths or /etc/paths.d/somefile didn't work. Tomcat and Hudson does still not see those directories.

• Collision Detection with SAT: False Collision for Diagonal Movement Towards Vertical Tile-Walls?

  - by Macks

  Edit: Problem solved! Big thanks to Jonathan who pointed me in the right direction. Sean describes the method I used in a different thread. Also big thanks to him! :) Here is how I solved my problem: If a collision is registered by my SAT-method, only fire the collision-event on my character if there are no neighbouring solid tiles in the direction of the returned minimum translation vector. I'm developing my first tile-based 2D-game with Javascript. To learn the basics, I decided to write my own "game engine". I have successfully implemented collision detection using the separating axis theorem, but I've run into a problem that I can't quite wrap my head around. If I press the [up] and [left] arrow-keys simultaneously, my character moves diagonally towards the upper left. If he hits a horizontal wall, he'll just keep moving in x-direction. The same goes for [up] and [left] as well as downward-diagonal movements, it works as intended: http://i.stack.imgur.com/aiZjI.png Diagonal movement works fine for horizontal walls, for both left and right-movement However: this does not work for vertical walls. Instead of keeping movement in y-direction, he'll just stop as soon as he "enters" a new tile on the y-axis. So for some reason SAT thinks my character is colliding vertically with tiles from vertical walls: http://i.stack.imgur.com/XBEKR.png My character stops because he thinks that he is colliding vertically with tiles from the wall on the right. This only occurs, when: Moving into top-right direction towards the right wall Moving into top-left direction towards the left wall Bottom-right and bottom-left movement work: the character keeps moving in y-direction as intended. Is this inherited from the way SAT works or is there a problem with my implementation? What can I do to solve my problem? Oh yeah, my character is displayed as a circle but he's actually a rectangular polygon for the collision detection. Thank you very much for your help.

• Why do I have to manually 'Restart Management Network' on vSphere 5 host after reboot to get networking available?

  - by growse

  I've got a couple of vSphere 5.0 hosts in a small lab environment here and I've noticed a strange behaviour. When on of the hosts gets rebooted, it is unresponsive to the network until I log into the ESX console, Press F2 to customize and select Restart management network. Once this is done, the networking works perfectly as expected. Each host has two NICs which are trunked together using Etherchannel to a Cisco 3750. The link is also a .1q VLAN trunk and the management network is configured on VLAN121 with the VM traffic configured on VLAN118. Why would the host be completely dead to the world until I physically kick it?

• Getting Pango-WARNING: Invalid UTF-8 string passed to pango_layout_set_text()

  - by geerlingguy

  About three days ago, I noticed the exim mailqueue started filling up on one of my servers, and upon inspecting some of the emails using # exim -Mvb $ID, I noticed they were being sent to some system email address (which is not a real address), and the body of the messages were as follows: (process:8259): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text() I'm wondering what could be causing this strange issue, as I've never heard of 'pango' at all... I've never seen that function used in my lifetime! It seems the process id (PID) is for an apache process, though, as the pids are always gone by the time I use # ps -aux to look them up. Edit: Whoops! Forgot to include the subject - looks like it's actually munin-cron that's bringing up the issue: Subject: Cron /usr/bin/munin-cron --force-root

• The Connected Company: WebCenter Portal - Feedback - Analytics and Polls

  - by Michael Snow

  Evernote Export body, td { }Guest Post by: Mitchell Palski, Staff Sales Consultant The importance of connecting peers has been widely recognized and socialized as a critical component of employee intranets. Organizations are striving to provide mediums for sharing knowledge and improving awareness across their enterprise. Indirectly, the socialization of your enterprise should lead to cost savings and improved product/service quality. However, many times the direct effects of connecting an organization’s leadership with its employees are overlooked. Oracle WebCenter Portal can help you bridge that gap by gathering implicit and explicit feedback. Implicit Feedback Through Usage Analytics Analytics allows administrators to track and analyze WebCenter Portal traffic and usage. Analytics provides the following basic functionality: Usage Tracking Metrics: Analytics collects and reports metrics of common WebCenter Portal functions, including community and portlet traffic. Behavior Tracking: Analytics can be used to analyze WebCenter Portal metrics to determine usage patterns, such as page visit duration and usage over time. User Profile Correlation: Analytics can be used to correlate metric information with user profile information. Usage tracking reports can be viewed and filtered by user profile data such as country, company or title. Usage analytics help measure how users interact with website content – allowing your IT staff and business analysts to make informed decisions when planning development for your next intranet enhancement. For example: If users are not accessing your Announcements page and missing critical information that they need to be aware of, you may elect to use graphical links on the home page to direct more users to that page. As a result, the number of employee help-requests to HR decreases. If users are not accessing your News page to read recent articles, you may elect to stop spending as much time updating the page with new stories and cut costs in your communications department. You notice that there is a high volume of users accessing the Employee Dashboard page so your organization decides to continue making personalization enhancements to the page and investing in the Portal tool that most users are accessing. Usage analytics aren’t necessarily a new concept in the IT industry. What sets WebCenter Portal Analytics apart is: Reports are tailored for WebCenter specific tools Report can be easily added to a page as simple as a drag-and-drop Explicit Feedback Through Polls WebCenter Portal users can create, edit, take, and analyze online polls. With polls, you can survey your audience (such as their opinions and their experience level), check whether they can recall important information, and gather feedback and metrics. How many times have you been involved in a requirements discussion and someone has asked a question similar to “Well how do you know that no one likes our home page?” and the response is “Everyone says they hate it! That’s all anyone complains about.” No one has any measurable, quantifiable metric to gauge user satisfaction. Analytics measure usage, but your organization also needs to measure the quality of your portal as defined by the actual people that use it. With that information, your leadership can make informed decisions that will not only match usage patterns but also relate to employees on a personal level. The end result is a connection between employees and leadership that gives everyone in the organization a sense of ownership of their Portal rather than the feeling of development decisions being segregated to leadership only. Polls can be created and edited through the Poll Manager: Polls and View Poll Results can easily be added to a page through drag-and-drop. What did we learn? Being a “connected” company doesn’t just mean helping employees connect with each other horizontally across your enterprise. It also means connecting those employees to the decisions that affect their everyday activities. Through WebCenter Portal Usage Analytics and Polls, any decision that is made to remove a Portal page, update a Portal page, or develop new Portal functionality, can be justified by quantifiable metrics. Instead of fielding complaints and hearing that your employees don’t have a voice, give those employees a voice and listen!

• What should a developer know before building a public web site?

  - by Joel Coehoorn

  What things should a programmer implementing the technical details of a web site address before making the site public? If Jeff Atwood can forget about HttpOnly cookies, sitemaps, and cross-site request forgeries all in the same site, what important thing could I be forgetting as well? I'm thinking about this from a web developer's perspective, such that someone else is creating the actual design and content for the site. So while usability and content may be more important than the platform, you the programmer have little say in that. What you do need to worry about is that your implementation of the platform is stable, performs well, is secure, and meets any other business goals (like not cost too much, take too long to build, and rank as well with Google as the content supports). Think of this from the perspective of a developer who's done some work for intranet-type applications in a fairly trusted environment, and is about to have his first shot and putting out a potentially popular site for the entire big bad world wide web. Also: I'm looking for something more specific than just a vague "web standards" response. I mean, HTML, JavaScript, and CSS over HTTP are pretty much a given, especially when I've already specified that you're a professional web developer. So going beyond that, Which standards? In what circumstances, and why? Provide a link to the standard's specification. This question is community wiki, so please feel free to edit that answer to add links to good articles that will help explain or teach each particular point. To search in only the answers from this question, use the inquestion:this option.

• Explicitly pass context object versus injecting with IoC

  - by SonOfPirate

  I have a layered service application where the service layer delegates operations into the domain layer for execution. Many of these operations need to know the context under which they are operation. (The context included the identity of the current user, culture information, etc. received from the caller.) For example, I have an API method that returns a list of announcements. The list is based on the current user's role and each announcement is localized to their culture. The API is a thin-facade that delegates to an Application Service in my domain layer. The Application Service method obviously needs to know the context of the current request/operation as another call to the same API from another user should result in a different list. Within this method, we also have logging that uses some of the context information so we a clear understanding of the context when the operation was performed (this is especially useful if something goes wrong.) While this is a contrived example, in the real world, my Application Services will coordinate operations with many collaborative components, any number of them also needing the context information. My choice is to pass the context to the Application Service which would then pass it with any calls to collaborators or have the IoC container satisfy the dependency the Application Service and any collaborators have on the context. I am wondering if it is considered good/bad, best practices/code smell, etc. if I pass the context object as a parameter to the domain methods or if injecting the context via an IoC container is preferred. (EDIT: I should mention that the context object is instantiated per-request.)
