• Using Ogre with android [closed]

  - by Rich

  I am trying get Ogre 3d to work on android, I have managed to download and run the ogre sample browser but I am really struggling with trying to get a basic application working i have been trying for days now with no avail. Does anyone have any pointers on where to start with this? Thanks if anyone can help EDIT: Very sorry for my rubbish question! I am a bit new to this and I am just trying to seek some guidance. Ok so i followed the instructions on the Ogre wiki to build ogre for android and the sample browser here: http://www.ogre3d.org/tikiwiki/tiki-index.php?page=CMake+Quick+Start+Guide&tikiversion=Android so it is deffinately possible. The issue I am having is knowing what I need to do to get started with ogre e.g just a simple hello world style app where it might just show the ogre head, so tutorials might actually be good because I could not really find any simple ones as I am very new to 3D development. I just found that the sample browser was just massive and yes it has everything in it but it's very difficult to understand how it all works. What I am asking is basically some help, as I have been trying to pull out some parts of the sample browser to just create a view with a 3D model. Hope this is better?

• Facebook Payments & Credits vs. Real-World & Charities

  - by Adam Tannon

  I am having a difficult time understanding Facebook's internal "e-commerce microcosm" and what it allows Facebook App developers to do (and what it restricts them from doing). Two use cases: I'm an e-com retailer selling clothes and coffee mugs (real-world goods) on my website; I want to write a Facebook App that allows Facebook users to buy my real-world goods from inside of Facebook using real money ($ USD) I'm highschool student trying to raise money for my senior class trip and want to build a Facebook App that allows Facebook users to donate to our class using real money ($ USD) Are these two scenarios possible? If not, why (what Facebook policies prohibit me from doing so)? If so, what APIs do I use: Payments or Credits? And how (specifically) would it work? Do Facebook Users have to first buy "credits" (which are mapped to $ USD values under the hood) and pay/donate with credits, or can they whip out their credit card and pay/donate right through my Facebook App? I think that last question really summarizes my confusion: can Facebook users enter their credit card info directly into Facebook Apps, or do you have to go through Payments/Credits APIs as a "middleman"?

• windows 7 frequently crashes when running 64 bit debian on virtualbox

  - by erin c

  I've been having some hard times with Virtualbox. I use it to run 64-bit Debian guest on a Windows 7 host to be able to code for linux systems. It generally crashes when I build my code in eclipse cdt, or if I am doing some intensive operations. Should I lower the memory and core usage? Is this some sort of virtualbox problem? I upgraded to virtualbox v4.1.8 and the problem still occurs. My virtual machine instance uses 1736MB out of 4GB of ram, and I use 2 out of 8 processor cores. But still, the whole thing crashes 1 or 2 times every single day.

• How can I guess if a USB cable will power my devices?

  - by rsanchez

  I've had problems with one long (4 meter) USB Mini-B to USB Type-A cable not being able to boot a 2.5'' external hard disc due to not supplying enough current. On top of that, the cable used a Type-A to Mini-B adapter for the Mini-B part, which probably made things worse. Three different shorter cables I got around made the hard disk work without extra current, so it was definitively the cable's fault. However, if I plugged the hard disk to the power, and used the long cable just for data it worked. Here is some related information on powering through USB cables: http://www.girr.org/mac_stuff/usb_stuff.html I have not any long cables that don't have an intermediary Type-A to Mini-B adapter to try them out. My question is: is there a way to guess if a cable will provide enough power for charge/disk drive power? Is it related to the length of the cable, to the build quality of the cable, or the fact that uses intermediary adapters?

• Rebuild an existing Rackspace server from scratch?

  - by Mojo

  In the process of working out kinks in a server build, is it possible to re-bootstrap a server from scratch, image and all? (Same flavor, say.) By that I mean without recreating the server, keeping its IP address if nothing else. I can't find a way to do this. It would have some advantages, I should think: It wouldn't decrement the 'server create' quota. The existing server would keep its IP address. One machine of a cluster could be rebuilt to a new image without having to change the IP address. (Maybe load balancers make IP addresses a moot point, but it still seems like a worthwhile task.)

• Bluetooth Connectivity that an error

  - by eka anggraini

  I have a bluetooth USB, every time I enter the bluetooth, bluetooth is active only a few seconds, after which it can not be used again In 'devices and printer' there is still a bluetooth but if you want to save the settings it can not, there are error message or bluetooth is revoked. I am using windows 7, whereas if use Windows XP smoothly no problems. This not only happens on my computer alone, my friend who has a build-in bluetooth also experienced the same thing with the same OS. Is there a patch / fix / update for its Windows? I've been brain-tweaking drivers for all but still can not.

• Inserting new 'numbered item' on Word 2010

  - by MarceloRamires

  I have a very simple problem in Word 2010. I have a document with a Table of Contents, and I have the following items: 1. Title 1  [some text]   1.1 Title 1.1    [some text] I simply want to add an item 1.2. If I go at the end of Title 1.1 and press enter, an item 1.2 appears below it, but the text regarding item 1.1 stays below it all. I somehow used to be able to do it on word 2007, but I can't remember what I used to do, and before struggling in it for too long, I remembered SuperUser. Can someone answer this and maybe additionally link me to a tutorial on this ? Every one I find talks about having a text already numbered and adding a TOC in the beginning. I want to build the text all over the TOC.

• new pc..noisy fan

  - by BRQ

  It's a new build, but it's always had noisy fans. From start to end, they will not stop running. The case is a cooler master which I believe comes with a fan that is not controlled by BIOS (according to technician), so that may be the source of the problem..but my lack of knowledge on the matter prevents me from making a reasonable assessment. Here are readings from CoreTemp: Model: Intel Core i7 870 (Lynnfield) Platform: LAG 1156 (Socket H) Frequency: 1658.23MHz (132.66 x 12.5) Tj. Max: 99 C Core #0: low= 34 C; high= 42 C; Load= 0% Core #1: low 31 C; high 42 C; load= 0% Core #3: 35 C; 42 C; 0% Any input will be appreciated.

• Can I fully disable my PCIe Video/Graphics Card per BIOS/Software?

  - by Jook

  Because of a quite noisy fan of my HD6700 I was wondering, if I could fully disable my video card through BIOS or even some Software/Windows. Switching to Intel I7 2600 internal video helped already with the noise, but it would be great to have the HD6700 only build in, but not activated/powered. So that the fan could stay compleatly off. Of course, I could just remove the video card, but I would like to avoid that. Is there any way? My Mainboard is an ASUS P8H67-M Pro, with Intel I7 2600 and ATI HD6500

• Understanding why a 450W power supply is destroying my ATX motherboards but not mATX

  - by T. Webster

  Maybe I'm missing something really obvious here, but after going through 3 new motherboards in trying to build my new machine, I'm finally certain that the 450W power supply I bought has been destroying them. It seems like it should be simple: just connect the connectors where they fit and switch the thing on. But today after hooking it to my ASUS Sabertooth 990FX TUF Series Motherboard and switching it on, I could see and smell the smoke coming out of the motherboard. What I don't get is why I can hook this same 450W power supply up to my mATX motherboard and not run into the same problem. What am I missing here? Where on the box or manual is this? (I have 8x2 GB RAM, AMD FX-4100 3.6GHz CPU, 1 512MB ATI graphics card, 1 WD 7200 RPM SATA hard drive. )

• Host a SSTP VPN Server on Windows 8

  - by Maarten

  I have a small server computer running Windows 8 at home. Currently it is hosting a PPTP VPN server using the build-in Windows 8 functionality for that. What I would want is something more secure, like an SSTP VPN server. However, I can't find any functionality of windows 8 or 3rd party software that can HOST a SSTP vpn server on Windows 8. I've only seen Client stuff and vpn pass trough services via google, all which i don't want/need. The only HOST stuff i find via google is the PPTP i set up currently. Is there any way of hosting a SSTP VPN server on my home machine? Thanks in advance, Maarten

• Compiling custom kernel 3.7.x lowlatency on Ubuntu 12.04

  - by FlabbergastedPickle

  All, I have a peculiar problem with trying to compile a lowlatency flavor of the latest 3.7 kernel. I retrieved the prepatched source from the launchpad using bzr, compiled it using the usual make-kpkg using the current config file plus default options for the rest, installed the kernel and booted into it. Everything works except for the fglrx and wl drivers that I had to install in the original 12.04 lowlatency kernel. So, I tried recompiling these and succeeded with both of them (no errors were reported)--wl driver required a minor adjustment to system.h include while latest fglrx 12.11 beta11 (released yesterday, Dec. 3rd, 2012) compiled without the hitch. Yet, when I try to modprobe either module (both having in common the fact that they were built after the kernel, fglrx as a deb, and wl via the usual make/make install), I get "FATAL: no MODULENAME module found" (MODULENAME being either wl or fglrx). The graphic driver watermark shows 3D crossed out and "for testing purposes" (or "unsupported hardware," can't remember), and no fglrx or wl is loaded. More mysteriously, dmesg shows no attempt on kernel's behalf to load the said drivers, even though they are clearly in the right /lib/modules/KERNEL_VERSION folder. How is this possible? Has something fundamentally changed in 3.7 kernel that would prevent modprobing of these? I know that there is driver signing option that was merged recently but as far as I could tell the kernel config file generated by the build process had that disabled. OTOH, while building wl driver, I did get a warning that the driver was not signed... Then again, even if the kernel disallowed loading of those modules, shouldn't dmesg reflect that? Any thoughts on this one are most appreciated.

• How to manage many mobile device users at server side?

  - by Rami

  I built a social Android application in which users can see other users around them by GPS location. At the beginning thing went well as I had low number of users, but now that I have increasing number of users (about 1500 +100 every day) it has revealed a major problem in my design. In my Google App Engine servlet I have static HashMap that holds all the users profiles objects, currently 1500 and this number will increase as more users register. Why I'm doing it? Every user that requests for the users around him compares his GPS with other users and checks if they are in his 10km radius. This happens every five minutes on average. Consequently, I can't get the users from db every time because GAE read/write operation quota will tear me apart. The problem with this design is? As the number of users increases, the Hashmap turns to null every 4-6 hours, I think that this time is getting shorter, but I'm not sure. I'm fixing this by reloading the users from the db every time I detect that it becomes null, but this causes DOS to my users for 30 sec, so I'm looking for better solution. I'm guessing that it happens because the size of the hashmap. Am I right? I have been advised to use a spatial database, but that means that I can't work with GAE any more and it means that I need to build my big server all over again and lose my existing DB. Is there something I can do with the existing tools? Thanks.

• Problem with installing Nvidia display drivers on Ubuntu 13.10

  - by Pascal

  Hello everyone and thank you for taking a look at this topic! I'm currently trying out Ubuntu 13.10 but I keep hitting a wall when it comes to installing a driver. I've tried: sudo apt-get install nvidia-current This resulted in a un-bootable system. The screen just stayed black and the cursor displayed as an 'X'. After that I did had to re-install Ubuntu. The computer I'm using is an Acer-Aspire-V3 with a build in Nvidia geforce GT 630M and also with a Intel HD graphics chip-set (not sure if chip-set is the right word here). "lspci | grep VGA" output: pascal@pascal-Aspire-V3-571G:~$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev a1) I've searched a bit here and there and found out that it would be wise to mention that this laptop is using (or so I think) Nvidia Optimus, not sure if it will add anything to the subject but at least I'll mention it just to be sure. Now to the questions: Q1 How is this caused and how can I fix it? Q2 What additional information could I provide to help you help me?

• NetBeans has broken interface with OpenJDK

  - by Krzysztof Stanislawek

  Sorry for English. Usually (say, at 4/5 of times), when I start NetBeans, interface is partially broken. For example, menu items are appearing and at once disappearing after click; some parts of editor are also blocked for cursor actions. Another issue is broken Options window - I can show it only once for NetBeans execution. There are more similar issues. $ java -version java version "1.7.0_55" OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1ubuntu1~0.13.10.1) OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode) Version of NetBeans is 7.0.1. Linux version is Mint 16. I use Mate. I had the same issue at other computer, at the same operating system. I know that installing Sun version of Java could help, but I also know that there shouldn't be such issue with OpenJDK. Also, I had other problem with NetBeans and Sun Java 8 - NetBeans suddenly crashed before he fully started, so I want to stick with OpenJDK. What causes my problem? Should I use other version of NetBeans/OpenJDK?

• Where to obtain openssl-devel for SunOS 5.10

  - by user35949

  So I am having an issue that I have seen other people have on many different systems. I have to build Subversion on a SunOS 5.10 box and have run into issues. I have the openssl source code installed and in the subversion-1.6.9 folder, I run the following: ./configure --with-ssl --with-libs=/opt/exp/lib/openssl/lib and receive the error: checking for library containing RSA_new... not found configure: error: could not find library containing RSA_new configure failed for neon I have also tried running the command without the "lib" on the end of the --with-libs path. I read online that I need the openssl-devel packages, but I have been unable to find them for SunOS 5.10, and they do not show up already installed on my system when running pkginfo. I have looked online including http://www.sunfreeware.com/ which I was told was a good SunOS software source. Any help you can provide would be welcomed. Thanks, Sean

• Trying to compile from source newest apache with newest openssl

  - by AlexMA

  I need to install apache 2.4.10 using openssl 1.0.1i. I compiled openssl from source with: $ ./config \ --prefix=/opt/openssl-1.0.1i \ --openssldir=/opt/openssl-1.0.1i $ make $ sudo make install and Apache with: ./configure --prefix=/etc/apache2 \ --enable-access_compat=shared \ --enable-actions=shared \ --enable-alias=shared \ --enable-allowmethods=shared \ --enable-auth_basic=shared \ --enable-authn_core=shared \ --enable-authn_file=shared \ --enable-authz_core=shared \ --enable-authz_groupfile=shared \ --enable-authz_host=shared \ --enable-authz_user=shared \ --enable-autoindex=shared \ --enable-dir=shared \ --enable-env=shared \ --enable-headers=shared \ --enable-include=shared \ --enable-log_config=shared \ --enable-mime=shared \ --enable-negotiation=shared \ --enable-proxy=shared \ --enable-proxy_http=shared \ --enable-rewrite=shared \ --enable-setenvif=shared \ --enable-ssl=shared \ --enable-unixd=shared \ --enable-ssl \ --with-ssl=/opt/openssl-1.0.1i \ --enable-ssl-staticlib-deps \ --enable-mods-static=ssl make (would run sudo make install next but I get an error) I'm essentially following the guide here except with newer slightly newer versions. My problem is I get a linker error when I run make for apache: Making all in support make[1]: Entering directory `/home/developer/downloads/httpd-2.4.10/support' make[2]: Entering directory `/home/developer/downloads/httpd-2.4.10/support' /usr/share/apr-1.0/build/libtool --silent --mode=link x86_64-linux-gnu-gcc -std=gnu99 -pthread -L/opt/openssl-1.0.1i/lib -lssl -lcrypto \ -o ab ab.lo /usr/lib/x86_64-linux-gnu/libaprutil-1.la /usr/lib/x86_64-linux-gnu/libapr-1.la -lm /usr/bin/ld: /opt/openssl-1.0.1i/lib/libcrypto.a(dso_dlfcn.o): undefined reference to symbol 'dlclose@@GLIBC_2.2.5' I tried the answer here, but no luck. I would prefer to just use aptitude, but unfortunately the versions I need aren't available yet. If anyone knows how to fix the linker problem (or what I think is a linker problem), or knows of a better way to tell apache to use a newer openssl, it would be greatly appreciated; I've got apache 1.0.1i working otherwise.

• AllSparkCube Packs 4,096 LEDs into a Giant Computer Controlled Display

  - by Jason Fitzpatrick

  LED matrix cubes are nothing new, but this 16x16x16 monster towers over the tiny 4x4x4 desktop variety. Check out the video to see it in action. Sound warning: the music starts off very loud and bass-filled; we’d recommend turning down the speakers if you’re watching from your cube. So what compels someone to build a giant LED cube driven by over a dozen Arduino shields? If you’re the employees at Adaptive Computing, you do it to dazzles crowds and show off your organizational skills: Every time I talk about the All Spark Cube people ask “so what does it do?” The features of the All Spark are the reason it was built and sponsored by Adaptive Computing. The Cube was built to catch peoples’ attention and to demonstrate how Adaptive can take a chaotic mess and inject order, structure and efficiency. We wrote several examples of how the All Spark Cube can demonstrate the effectiveness of a complex data center.

• Organizing files relationally in Windows 7?

  - by Cayetano Gonçalves

  I just took a new job as a policy analyst, and after even one week keeping track of hundreds of files- lawsuits, legislation, letters, etc- in Windows 7 is proving difficult. In my last job I was a database architect and I helped build Linux based servers to track files among an entire department, however there is no way for me to do that at this time in this job. Is there any way to track files/indices/locations/tags/themes and store them in some kind of RDBMS system, instead of storing the files in folders that only allow for flat and fixed storage? For example, if I have a file that deals with: ELID organization Appeals court John Smith It really is inconvenient to have to decide which one of these tags to create into a folder and place the file into it, when it falls under all the categories. Even if I could place tags the way you can in Stack Exchange on files, it would solve a lot of heart ache.

• LinkSys WRT54GL + AM200 in half-bridge mode - UK setup guide recommendations?

  - by Peter Mounce

  Crossposted from here I am basically looking for a good guide on how to set up my home network with this set of hardware. I need: Dynamic DNS Firewall + port-forwarding VPN Wake-on-LAN from outside firewall VOIP would be nice QoS would be nice (make torrents take lower priority to other services when those other services are happening) DHCP Wireless + WPA2 security Ability to play multiplayer computer games I am not a networking or computing neophyte, but the last time I messed with network gear was a few years ago, so am needing to dust off knowledge I kinda half have. I have read that I should be wanting to set up the AM200 in half-bridge mode, so that the WRT54GL gets the WAN IP - this sounds like a good idea, but I'd still like to be advised. I have read that the dd-wrt firmware will meet my needs (though I gather I'll need the vpn-specific build, which appears to preclude supporting VOIP), but I'm not wedded to using it. I live in the UK and my ISP supplies me with: a block of 8 static IPs, of which 5 are usable to me a PPPoA ADSL2+ connection

• Trouble installing Mercurial 1.5 on Mac OS X 10.5.8 (without using MacPorts)

  - by gjvis

  I'm having trouble installing Mercurial 1.5 (build 20100307) from the prebuilt installer on Mac OS X 10.5.8. The installer is halting telling me that I need to install Python 2.6 to continue. I've installed the latest version of Python (2.6.5) twice now but it's not helping. which python is reporting /Library/Frameworks/Python.framework/Versions/2.6/bin/python, but I can see that I also have 2.3 and 2.5 in /System/Library/Frameworks/Python.framework/Versions directory, which I suspect is being picked up by the installer ahead of the 2.6 install. If possible I'd like to install Mercurial and Python without having to resort to MacPorts, but if that is the only option then so be it :)
