• Ubuntu 12.04 3.2 Kernel showing incorrect "cache size" in cpuinfo?

  - by Tom G

  2x Xeon E5620 . 16 Cores altogether. /proc/cpuinfo shows cache is only @ 4096kb According to intel this should have 12MB of "smart cache". Doing searched for E5620 and CPUinfo shows the correct number: cache size : 12288 KB However mine shows this: processor : 15 v endor_id : GenuineIntel cpu family : 6 model : 44 model name : Intel(R) Xeon(R) CPU E5620 @ 2.40GHz stepping : 2 microcode : 0x1 cpu MHz : 2400.104 cache size : 4096 KB fpu : yes fpu_exception : yes cpuid level : 11 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush mmx bogomips : 4800.20 clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual Any idea on why it shows like it's missing 8MB in CPU cache? .

• 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.

• Extend university wifi network [migrated]

  - by asfasdoiuh ouhouhouh

  i live in a university campus and i can get wifi signal on the outside of my window but not in the house. The solution i use at the moment is a usb wifi dongle outside connected to my laptop but the lack of an internal antenna make the connection quite unreliable at times. So i was trying to find another solution to improve the reception of my network. One idea is to setup a router on the outside (in a place with stronger signal) and redirect the connection inside the house with an ethernet cable but the problem is that our Uni Wifi is managed by a capitve portal (BlueSocket with DNS redirection to login page) and the authentication has to happen on the mac address that connect to the net (so the client appliance in this case). If I use a router with Mac-Clone capability i will be able to be redirected trough the captive portal on my laptop computer and login from there or i need to setup my router to fill in the login page by itself? There are other hardware/software solutions i can use to get what i want? Thank you all

• Audio input problem in Ubuntu 9.10

  - by Andrea Ambu

  My audio input is a mix of my mic output and my sound card output. I'd like it to be just my mic output. I was able to do so in Ubuntu 9.04 but the interface is 9.10 is totally changed and I tried every my creativity was able to think. It's really annoying when talking to other people over the internet because they keep hearing their voice back. I'm not sure I explained it in clear way so I'll give you an example: What I do: I put an mp3 on play or a video on youtube then open a recorder and start to talk on my mic. What happens: both my voice and audio from mp3/youtube get reordered, even if I put headphones volume to 0 (via hardware). What I'd like to happen: Only my voice should be recorded. I'm sure I'm missing some technical term, but that's the problem and I'd like to solve it in Ubuntu 9.10, any idea?

• What sort of data should be sent for mouse-based movement in a multiplayer game?

  - by Daniel

  I'm new to the Multiplayer Rodeo here so please bear with me... I am just getting started and I'm trying to figure out how to deal with movement. I've looked at the question Best way to implement mouse-based movement in MMOG which gives me a pretty good idea, but I'm still struggling with what kind of data should be sent to the server. If a player is on position [x:0, y:0] and I click with the mouse on [x:40, y:40] to start movement, what information should I send to the server? Should I calculate the position based on velocity on client side and just send the expected location? Or should I send current location and velocity and direction? When the server is updating the clients on the players' whereabouts, should the position be sent only, and the clients expected to interpolate/predict movement, or can the direction sent from the client (instead of just coordinates) be used. My concern(or confusion) is regarding the ping/lag frequency of data update and use of a predictive algorithm, as I'd like the movement to be smooth even with a high latency, and prevent ability to cheat(though that's not the top priority).

• How can I make this arcade-highscore game more fun/interesting?

  - by j-a

  I'm having difficulties getting the fun factor into this iPhone game, and I am looking for some ideas or advice. I was asked to generalize the question a bit. What are some techniques for arcade highscore games that can be applied to this game in order to: Make each second of the game fun and challenging, from the first second to the end of the game. Regardless of skill level. Make the player want to try again and again to beat the high score. Briefly about the game: you aim using your finger and pull the bow chord and release by lifting your finger. That part feels quite nice how the bow interacts with the finger. The game idea: hearts fall down and you get 1 pt for each heart you shoot. You start with a few arrows and every now and then a bag of arrow comes down which - if you hit it, you get more arrows. Once your out of arrows the game is over. So it is all about beating your previous high score or your friends high scores. Unfortunately I don't find it that fun. Thankful for any ideas/suggestions/thoughts on how to make it more fun/interesting.

• Using a CDN for CMS software (multiple sites)

  - by SmokeyPHP

  I'm currently researching ideas for the media management side of a CMS I'm writing. I was looking at having images served from a CDN which is fine on a single site, but I want all sites that run the CMS to make use of a CDN (which will most likely be a custom developed one, rather than a third party service like S3). My main question is: Is a multi-site CDN a good idea? I can't think of a downside, but have probably missed something - obviously they won't share the same folder, as I invisage the requests to be css.cdnsite.com/example.com/style.css or something along those lines. Having multiple sites in the same place will obviously make it easier for us to manage, as well as being cheaper, but then I wonder if it'll be worth it... Long story short: How should the CMS handle user uploaded media (separate installations) Just keep a local copy of all assets and serve them from the same site, like in days of yore? Keep a local copy, force site to use www. and have CDN subdomains per site? Or use a single separate CDN for all sites? Apologies for the length of this question, not sure if this should be multiple questions or not, as all parts are kind of related and could affect each other.

• Cygwin file and directory user and group

  - by dvanaria

  I use Cygwin as my main development environment on both my home and work computers. In order to share files between the two computers, I use Dropbox, which is installed in the following folder on both computers: c:\cygwin\home\dvanaria\dropbox Everything works great, except for one thing. When I'm working on my home computer and do an ls -l on any directory, all the files show up as owned by dvanaria of group Users. But when I work from my work computer, an ls -l shows all files as being owned by Administrators and of group Domain Users. I know Cygwin uses some kind of mapping between Windows users and permissions to the /etc/passwd file. But to be honest I have no idea how this file works or how it maps to Windows under Cygwin. Could anyone help figure this out? The main problem is that I can't edit any files when using my work computer, only read them.

• Java game design question (graphical objects)

  - by vemalsar

  Hello Guys, I'm beginner in game development, in Java and here on this site too and I have a game design question. Please comment my idea: I have a main loop which call update and draw method. I want to use an ArrayList which store graphical objects, they have coordinate and image or text to draw and my game objects extends this class. In update, I can choose which objects should be put in the array and in draw method I'll display the elements of array on the screen. I'm using a buffer and draw first there, but it is not important now I guess...Here is a simple (not full) code, only the logic: public class GamePanel extends JPanel implements KeyListener { ArrayList<graphicalObjects> graphArray = new ArrayList<graphicalObjects>(); public void update() { //change the game scene, update the graphArray, process input etc. } public void draw() { //draws every element of graphArray to a JPanel } public static main(String[] args) { while(true) { update(); draw(); } } } My questions: Should have I use interface or abstract class for graphicalObjects? graphicalObjects class and the ArrayList really needs or there is some better solution? How to draw objects? They draw themself with their own method or in the draw method I have to draw manually based on graphicalObjects variables (x,y coordinates, image etc.)? If this conception is wrong, please suggest another one! All comments are welcome and sorry if this is dumb question, thanks!

• Java application not starting in Tomcat, Plesk 9 server

  - by netagence

  Hi I have a Plesk 9.3 CentOS 5 server on which I installed the addon to have Tomcat functions. One application I have uploaded appears in the Plesk Tomcat user panel but with a yellow exclamation mark and the error "Actual status of the application does not correspond to the status retrieved from the database". The app therefore does not run, while other uploaded test .war applications do. The server runs Tomcat tomcat5.5.23-0jpp.7.el5_2.1 which matches the requirements for the required app according the the company that made it. While searching for the solution I could find all 3 uploaded .war applications in /usr/share/tomcat5/psa-wars/domainhere.com/ but they do not seem uncompressed there even though 2 of them run fine. Not enough Tomcat / Java knowlede to go on... Any idea to help me here ? Best regards.

• BUILD 2013 Sessions&ndash;Building Great Windows Phone UI in XAML

  - by Tim Murphy

  Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/06/27/build-2013-sessionsndashbuilding-great-windows-phone-ui-in-xaml.aspx Even the simplest of smart phone apps can be a challenge to give a compelling UI regardless of the platform.  Windows Phone and XAML are no exception.  That is what got my interest in this session by Shawn Oster.  He took a checklist type approach to the subject is good considering that is about the only way that many us get things done. Shawn started out giving us a set of bad design/good design examples.  They very effectively showed how good design gives a sense of professionalism to your app that could determine if your wonderful idea actually makes money is DOA. I won’t go over all his points since you will be able to get the session online, but a few of his checklist points included design from the beginning instead of as an afterthought, not being afraid to leave white space and making sure your application elegantly supports both landscape and portrait modes.  The many gems make this a must watch for any developers who struggle with visual design. del.icio.us Tags: BUILD 2013,Windows Phone,XAML,Design

• There is a way to change the SkyDrive default path in Windows 8.1?

  - by RobsonROX

  The deeper integration with SkyDrive is truly beneficial, but my laptop has a somewhat small primary drive (an 128 Gb MSATA SSD), and when possible, i try to move installations and other folders(like Documents and Downloads) to the secondary, 1 Tb drive. But i couldn't find any option to change the SkyDrive folder (it used to be in the secondary drive prior to the upgrade). Anyone have some idea how to change it? Thanks in advance! Edit 1: I've looked for an option to change this folder, to no avail. Really, it could only be a problem if i choose the option to keep my files offline, but it is exactly the option that i was looking for. Edit 2: Trying to install the old desktop app, the installer just quits silently.

• PPTP: Linux clients unreachable

  - by Bahman

  I have setup a PPTP server on a CentOS 6 box. Several clients (Windows and Linux) connect to this server. All clients use the same subnet. All clients (Win or Lin) can surf the Internet using the VPN successfully. Windows clients can ping any other Windows client (XP/Vista/7) connected to VPN. Linux clients (KVPNC) can ping any Windows client (XP/Vista/7) connected to VPN. So far so good. But there's this weird problem and I've been trying to figure it out with no luck: No client can ping (reach) a Linux client (successfully) connected to VPN. And yes, the firewall is completely disabled. I'd really appreciate any hint/idea. TIA, EDIT: The ultimate goal of this is to share services across the VPN, like accessing a HTTPD running on a Linux box from a Windows client.

• Blocking popups and ads

  - by user74364

  I'm having a fight with ads, popups and tracking cookies. But i'm having some issues. Software used: Chromium 18.0.1025.168 Extensions used: Adblock Plus (Beta)1.2 AdBlock+ Element Hiding Helper1.1.9.18 Better Pop Up Blocker2.1.6 Ghostery3.0.0 With this configuration, i'm always getting this error: Warning: This extension failed to modify a network request because the modification conflicted with another extension. I know if i disable "better popup", this goes away. It's perfectly normal, due to those extensions trying to block the same things. Problem is, i can't live without all of them! Can anyone advise me about some good configuration? Can't live without adblock plus, because i hate ads. Betterpopup blocker is essential too (believe me, chrome doesn't block a lot of popups, and i have a website or 2 that can proove that.) And ghostery is a must... i can't bare the idea of being tracked all the time by some companies. So i'm kinda lost here! everything is needed, but they conflict with each other. i mean, it has to exist a perfect combination out there, i know i'm not the only one hating the privacy issues nowadays! really thankful for any tips guys

• How can we best petition to bring Adobe creative software to Ubuntu?

  - by Sixthlaw

  Now I know its not as simple as asking for Adobe to support their design software on Ubuntu, but is there a way for the community and Canonical to make known to Adobe the rapidly growing amount of Linux users, and their desire for this great set of tools OFFICIALLY? I know that many of the answers I receive might be of the fashion "Its not going to happen", "use the free tools provided" or "Who knows it might happen in the near future", but this IS not what I am looking for. I have noticed, on sites like www.OmgUbuntu.com, there are links to pages where people can "like" the idea. Is there a way to try and get the whole community on board with this one, even Canonical, and as stated above, put forward this proposal to Adobe. The current requests for an Adobe CS, for Linux, are in dribs and drabs scattered all of the internet. Now is the best time to come up with productive solutions on how we can best gather statistics on the amount of people willing to buy the Adobe CS. These are the words of an Adobe employee: "I have forwarded this feedback on to the appropriate team who will consider it for future releases of Adobe software." The larger amount of people we have unified in the ONE community proposal, the greater chance we have of getting the software. How can we make this happen?

• Recover Lost data/partition

  - by Kaleido

  This is what happened: I was running 12.04.1 and wanted to install 12.10. upgrade, but a fresh install. When setting up my computer I anticipated for this by dividing my 640GB HD in following partitions: 1. 60 GB for Ubuntu, boot 2. 576 GB for data, mountpoint /home 3. swap, 4GB The idea was to manually select the correct partition in the installer but I got distracted for a moment and selected the wrong option. Result: The installer started repartitioning the entire HD. When I noticed this I interrupted the installer, but upon reboot it was clear that I was too late, no OS to boot to. I booted from a Gparted Live CD to see if I could recover the data on my previous /home-partition, but it's gone. Is there any way to recover the lost data? I searched around and read alot about Testdisk, but in all the tutorials I've seen, the set-up has been much easier than what I'm facing. I've not only lost my partition table, it's been replaced. Thanks in advance for any ideas that might help! If extra info is needed, please specify and I will do my best to provide.

• Selection Issues with a PDF from a Word document

  - by syrion

  I have a long Word document that has a running footer. When I try to copy and paste across pages in the PDF generated from this document, the behavior of this footer is unpredictable--sometimes it is unselected, sometimes it is selected, sometimes the footer on the next page is selected. I would prefer to make this portion of the document unselectable, so that it still shows up but doesn't interfere with copying and pasting. Does anyone have an idea of how to do this? No, changing it to an image isn't possible, because it includes a page number.

• I still can't figure out how to program!

  - by Mark K.

  Please help! I've read lots of programming books for various languages, Java, Python, C, etc. I understand and know all of the basics of the languages and I understand algorithms and data structures. (Equivilant of say 2 years of CompSci classes) BUT, I still can't figure how to write a program that does anything useful. All of the programming books show you how to write the language, but NOT how to use it! The programming examples are all very basic like build a card catalog for a library or a simple game or use algorithms etc... They dont't show you how to develop complex programs that actually do anything useful! I've looked a open-source programs on sourceforge, but they don't make much sense to me. There are hundreds of files in each program & thousands of lines of code. But how do I learn how to do this? There's nothing in any book I can buy on Amazon that will give me the tools to write any of these programs. How do you go from reading Intro to Java or Programming Python, or C Programming Language, etc.. to actually being able to say, I have an idea for X Program.. this is how I go about developing it? It seems like there is so much more involved in writing a program than you can learn in a book or from a class. I feel like there is someth Can anyone put me on the right track?

• Is it possible to use bittorrent for a fileserver

  - by sris

  I would like to set up a file server that is searchable, preferable via the web. I'm wondering if it would be possible to achieve this using the bittorrent protocol and have a single client sharing every single torrent on the server. I guess I could use some available tracker solution for the webinterface or write one myself. My concerns are the if there are any limits to the number of torrents a single client can share since this may potentially be 10k torrents. The number of downloading clients is very small, only myself and my relatives. The idea is to have a single place to host everything from vacation photos to musical creations. Is there any other options for this kind of file server. It should also be easy to upload files to the server.

• Why S3 website redirect location is not followed by CloudFront?

  - by ychaze

  I have a website hosted on Amazon S3. It is the new version of an old website hosted on WordPress. I have set up some files with the metadata Website Redirect Locationto handle old location and redirect them to the new website pages. For example: I had http://www.mysite.com/solution that I want to redirect to http://mysite.s3-website-us-east-1.amazonaws.com/product.html So I created an empty file named solutioninside my bucket with the correct metadata: Website Redirect Location= /product.html The S3 redirect metadata is equivalent to a 301 Moved Permanentlythat is great for SEO. This works great when accessing the URL directly from S3 domain. I have also set up a CloudFront distribution based on the website bucket. And when I try to access through my distribution, the redirect does not work, ie: http://xxxx123.cloudfront.net/solution does not redirect but download the empty file instead. So my question is how to keep the redirection through the CloudFront distribution ? Or any idea on how to handle the redirection without deteriorate SEO ? Thanks

• Network DFS Shares Jumping Back To Root

  - by Taz

  We map several network drives to DFS locations via a logon script. Recently we've had a number of users complain of a very unusual behaviour when navigating these shares. They will be going through folders and will get 'rubber-banded' back to the root of the share. This will happen for a few minutes and then go back to behaving normally. The users are on Windows 7 and the fileshare is on Windows Server 2K8R2. Any idea what could be causing this annoying behaviour?
