• How can WiFi access points recognize me?

  - by stephanos

  Due to heavy snowfall I was recently stranded on an airport. Having to do some surfing on my laptop I found an open access point. It offered 30 minutes of free surfing a day. I registered and used up my time. Then I wanted to see if I could use it again - mostly just for the fun of it. I opened a different browser then before and tried to register again. It didn't work. The access point recognized me and told me that I'd have to wait another day to get 30 free minutes again. I reconnected again to force a new IP - still the same. How did it recognize me?

• How to transfer a website hosted online to my Virtual Host

  - by user831740

  I'm doing some work on a webpage, meaning I gotta modify a few things. As a result of this I installed apache and all the things that come associated with it, and also installed Joomla, and I got everything running well. My problem is, I need to make apache run this website locally, so I downloaded the public_html folder from the FTP server on my website, but I have absolutely no idea how to implement the website in order to make it run on apache. I've read a few guides, but they all tell me how to create a new website instead of helping me host a website already done.

• Is it possible to create an "impossible" rooms in games?

  - by qwerty3000

  Forgive me my lack of knowlegde, but for quite a long time I asked myself whether it was possible to create a continous game space that some player could walk inside and so on, that would be absolutely impossible in reality, e.g. you have a very small house that allows you to go around it to see all sides and the full dimensions, and then, when you enter, it is like a giant hall, without any loading screen or (internal) "model change" and so on. I'm no game designer and I never needed to learn 3D-modelling, so I don't know what is possible and what isn't. And is this the same as Is the "impossible object" possible in computer graphics? this? Or is it just the same category, but not exactly the same question? Thanks.

• Setting up the GDM Theme

  - by Szymoninho

  I'm using Ubuntu 12.04 with Gnome Classic (no effects) and because of the fact that some system options have disappeared with the new system release I've been struggling with this for a while and despite this seems very easy I can't do this :/ - does anyone know how to choose a GDM Theme? I'm quite sure that GDM is now in use on my Ubuntu - I set it up with: sudo dpkg-reconfigure gdm Despite I moved the theme folder to /usr/share/gdm/themes nothing has changed by now, I've logged out and in a couple of times but everytime I get the standard log in window and wallpaper (different from mine). So I'll appreciate any kind of help from anybody, now I have absolutely no idea how to figure it out. Cheers.

• Windows 8 on iSCSI with LIO target: thin provisioning

  - by LubosD

  I have installed Windows 8.1 on an iSCSI target. This target is provided by Linux LIO and is backed by a sparse file. One of the reasons I created such an installation was thin provisioning. In other words, when I free disk space on Windows, LIO should punch holes into the file, thus free storage space on the Linux server as well. I have checked my kernel's sources and the SCSI UNMAP command is really supported for file-backed targets. On the other hand, deleting files on Windows doesn't lower the amount of space taken by the backing file on Linux (checked with du). Actually, the backing file sometimes grows even more. Some sources on Google say Win8 should support UNMAP/DISCARD on iSCSI, but even in Wireshark I only see ordinary read and write commands when files are being deleted. Any way to fix or troubleshoot it?

• What can I do in order to inform users of potential errors in my software in order to minimize liability?

  - by phobitor

  I'm an independent software developer that's spent the last few months creating software for viewing and searching map data. The software has some navigation functionality as well (mapping, directions,etc). The eventual goal is to sell it in mobile app markets. I use OpenStreetMap as my data source. I'm concerned about liability for erroneous map data / routing instructions, etc that might result when someone uses the application. There are a lot of stories on the internet where someone gets into an accident or gets stuck or gets lost because of their GPS unit/Google Maps/mapping app... I myself have come across incorrect map data as well in a GPS unit I have in my car. While I try to make my own software as bug free as possible, no software is truly bug free. And moving beyond what I can control, OpenStreetMap data (and street map data in general) is prone to errors as well. What steps can I take to clearly inform the user that results from the software aren't always perfect, and to minimize my liability?

• Are there some types of software that cannot be developed by all major programming languages?

  - by mbillard

  I'd like to know if some of the major programming languages can absolutely not be used to create some very specific types of software. By major programming language I mean the likes of C++, C#, Java, Ruby, Python. By "cannot be developed" I mean cannot be developed or it is unrealistic to do it due to performance, difficulty of implementation, etc. I've always thought that any programming language could be used to solve any problem but lately I've been thinking that some languages are unsuitable for some projects. If you can provide examples of such applications, it would be appreciated. Thanks.

• How to open-source a project whose git repository has copyrighted media in the history?

  - by phyzome

  I want to release an audio fingerprinting software project under a free license, but the repository contains copyrighted audio files. The test cases also currently use these files. How do I release the code to the public with maximum version history but without violating copyright? Details: The code is versioned under git. We will collapse it all back into one branch before release. There are 400 MB of audio data. Some files are free-licensed music from e.g. Jamendo, others are MP3s from our personal collections. No matter what approach we take, we'll always keep an immutable copy of the original repo, so as not to destroy project history. Main question: How to handle the public release? Expunge all history of the files in question from the git repository and release the altered repo. (v64 pointed out a way to do this.) Alternatively, take a snapshot of the current state of the code and don't even bother having a public history of the pre-release code. Side question: How could we have avoided this dilemma in the first place, given that sometimes private code or media is needed for the early stages of a project?

• Move 2TB Win7x64 to 640GB HDD

  - by reedacus25

  Basically I just got a new (refurbished) HP H8-1260t to use for Windows Media Center. The shipping drive is a 2TB Hitachi drive, but I have an older and barely used 640GB WD Caviar Blue 7200RPM drive I would like to move my Windows install to. I have about 750GB of data with over 1TB free left on the drive. Having googled my heart and fingers out, I would think that I can shrink my partition down to the size it is full at now with over 1TB free for a second partition where I can move my media files to further shrink my boot partition so that I can fit a system image smaller than 640GB on that WD drive. I want to have a separate drive for Media and TV Recordings from my boot disk. Does this sound like the easiest method for me? Or am I doing this all wrong. Help appreciated.

• How Do I get rid of this software? [closed]

  - by Marcus

  Some jerk who refurbished my computer intalled this crappy software instead of reinstalling my windows. I absolutely despise this crap. I cant do anything I could do on my PC before. I cant even save files to my computer correctly. I work from mozilla, i have a blackberry whose update manager cannot download on this crappy mainframe. Just tell me how to get windows back without having to buy it or buy a whole new computer. Or maybe just step your crappy ass game up

• Please help me debug this little C program on dynamic two-dimensional array? [migrated]

  - by azhi

  I am a newbie here. I have written a little C program, which is to create a two-dimensional matrix. Here is the code: #include <stdio.h> #include <stdlib.h> int **CreatMatrix(int m,int n){ int **Matrix; int i; Matrix=(int**)malloc(m*sizeof(int*)); for(i=0;i<m;i++){ Matrix[i]=(int*)malloc(n*sizeof(int)); } return Matrix; } int main(){ int m,n; int **A; printf("Please input the size of the Matrix: "); scanf("%d%d",&m,&n); A=CreatMatrix(m,n); printf("Please input the entries of the Matrix, which should be integers!\n"); int i,j; for(i=0;i<m;i++){ for(j=0;j<n;j++){ scanf("%d",&A[i][j]); } } printf("The Matrix that you input is:\n"); for(i=0;i<m;i++){ for(j=0;j<n;j++){ printf("%3d ",A[i][j]); } printf("\n"); } for(i=0;i<m;i++) free(A[i]); free(A); } I have run it, and it works fine. But I am not sure if it is right? Can anyone help me debug it?

• EXC_BAD_ACCESS error when box2d joint is destroyed

  - by colilo

  When I destroy the weldJoint in the update method (see below) I get an EXC_BAD_ACCESS error pointing to the line world->DestroyJoint(weldJoint); in the update method below: -(void) update: (ccTime) dt { int32 velocityIterations = 8; int32 positionIterations = 1; // Instruct the world to perform a single step of simulation.

Am I destroying the joint in the wrong way? I would really appreciate any help. Thanks

• What is the primary use of Vertex Buffer Objects?

  - by sensae

  From what I've read, it seems VBOs are purely for performance. I'm working on a very rudimentary learning project in lwjgl and I'm just trying to figure out what more advanced features of the library I should be delving into, and what their use is. My understanding is that VBOs allow a person to keep vertexes in VRAM while they aren't currently being drawn in a scene. In my case, I'm just drawing quads and performance probably isn't a concern at all, but I'm trying to piece together what's happening under the hood. If I'm drawing quads directly, I'm drawing from the CPU memory, correct? Also, if I'm not doing any checks for visibility, does that mean I'm rendering absolutely everything in the "scene", regardless of whether its in view? Are VBOs a way to store objects and only render what's needed?

• Game Development

  - by Sundareswaran Senthilvel

  I'm planning to write a game from scratch (a BIG Game, for commercial purpose). I'm aware that there are certain compute libraries like OpenCL, AMD APP SDK, C++ AMP as well as DirectCompute - both from MS (NOT interested in CUDA) are available in the market. I'm planning to write the game from the scratch, which includes the following engines... 1.Physics Engine 2.AI Engine 3.Main Game Engine (... and if anything is missed). I'm aware that, there are some free physics engine libraries in the market. Not sure about free AI engine libraries. I'm bit confused in choosing between the OpenCL, AMD APP SDK, and C++ AMP libraries (as already mentioned i'm NOT interested in CUDA). I want my game to be published in Windows/Android/Mac OSX. It means it should be a cross-platform game. I will be having "one source code" that i'll compile for various platforms like Windows/Android/Mac OSX, and any others if i missed. Note: Since I'm NOT a Java guy, kindly do NOT suggest me the Java Language. For Graphics language should i use OpenGL or DirectX 11? I have heard that OpenGL runs on a single core, and not sure of DirectX 11. Between OpenGL and DirectX which one should i follow? or else, are there any other graphics language that i need to start with? I want to make use of the parallelism in GPU as well as CPU.

• How can I install Ubuntu's 10.10 kernel I Ubuntu 12.10?

  - by user103533

  I did use Ubuntu 10.10 for a long time, and now I replaced it with Ubuntu 12.10, every thing works great, but I do have one little problem, which is with my wireless card. On Ubuntu 10.10, it worked PERFECTLY, and it even worked better than in windows 7, so I was very happy with Ubuntu 10.10, but, like I said, after installing 12.10, my wireless card doesn't work any more, so I heard that KERNELS are the reason for that. Are kernels the reason for my wireless not working now? If yes then please teach me how to remove my current kernels and install 10.10 kernels. I went to -Additional Drivers- and i found something very weird i took picture and this is what it look like "apply changes" Button NOT active so i can't install driver :( anyway... my Wireless card is WL-138g v2 (remember on Ubuntu 10.10 it was WORKING 100% normally and FREE i did NOT pay for it driver) so... now what shall i do ? it is saying in picture // Using Non-Free firmware for linux kernel drivers from linux-firmware-nonfree (proprietary) // BTW i did "rfkill list" but NO-thing appear under that command.

• Is there a single book that covers the breadth of computer science fundamentals? [closed]

  - by superFoo

  When I did my undergraduate studies in elecrical engineering, there was this book called "Basic Electricity" by Van Valkenburgh. If you read that book cover to cover, your fundamentals in electrical engineering would be bulletproof. I would recommend it all my juniors and I absolutely loved it. Is there such a book in the field of computer science? I am not so concerned about the algorithms. I am looking more into something that tells me how does everything work beneath the covers. TCPIP, memory management, DNS, routing, SSL, buffer, queuing etc.

• Java on 256MB system?

  For a school project, I've registered a free VPS on a hosting provider (pipni.cz). It has 256MB RAM: Mem: 262144k total, 148104k used, 114040k free, 0k buffers It's running on Debian Squeeze. I always get this error when I run a Java program: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I tried to use Xms, Xmx, Xss with low values and still same result. ulimit -v gives me "unlimited". My application will be pretty simple and I need to use rmiregistry also. Can somebody help?

• Vista Home Premium won't connect to network.

  - by Ice

  I deinstalled some software (e.g. some Toolbars for IE and Norton security suite, because the free trial period of 60 days is run out and so i want to switch to microsofts free security essentials). But now i cannot connect to the network again: Neither over LAN nor over WiFi. Neither with standard DHCP ON (sets a 169.254.x.y address) nor with fixed IP-Address. No error during changing the settings. Ping to the Gateway e.g. doesn't work and gives "generall failure". The DHCP-Client sets no IP-Address. There is allways only 'local access' on every network-connection. i ran out of ideas, please help. UPDATE per 2011-03-11: I followed each and every hint but nothing changed. I did a research on microsofts homepage through all the sites belonging to network but nothing helped. What can i do next?

• How to redirect a specific url through a proxy for multiple services?

  - by CrystalFire

  I have a website hosted on 000webhost.com for free. I am unable to connect directly to the site because Comcast has blocked a portion of 000webhost's servers for free accounts due to other people hosting malicious content. In order to maintain my website, I cannot use my computer to directly connect to the server. I am wondering if there is a way by which I can specifically forward attempts to access the server through a proxy, transparently. The current system that I am on is Windows, but I also have systems running Mac OSX and Linux, so solutions for any system could be fine. I've found answers which work for http, but I'm looking for a solution which will let me use all the other functions as well, such as ftp and ssh.

• What do you consider standard job perks? [closed]

  - by reseter

  What does a company need to offer you (apart from a fat pay cheque) for you to work for them? I am aware of this question, which is from an employer's perspective. I am interested in your views as employees. To get the discussion started, here is a list off the top of my head (not in any particular order): High-end computer with a huge screen or two. The best software tool money can buy as per Joel's test). That isn't too much to ask given many of the best tools are free (think git). Flexibility is a bonus- if a particular platform/ piece of software is not absolutely required, I would like to pick my OS and IDE. A quality chair Quiet workspace. Open plan is fine as long as there are meeting rooms so that there is no constant chatter going on around me. Spacious workspace. I would rather have more than three inches between my mouse and the person next to me's keyboard. Food and drink at work. Many companies these days have fruit baskets, biscuits, etc available to their employees, some even offer free lunch. Education. If my employer wants my skills to stay up-to-date, they should at the very least understand I need time to learn. If they want to pay for my books and conference registration fees, I am more than happy to accept. Other options include organizing internal knowledge exchange days or inviting speakers from outside. Flexible hours/ option to work from home is a bonus

• mongodb eating 48G in 1min

  - by ledy

  In mongodb i work with this collection: Size 55.93g Data Size 39.82g Storage Size 41.08g Extents 53 Indexes 4 Index Size 9.64g It takes few seconds of mongdb being up with this single collection and all 48GB RAM on the dedicated server are gone. That's worse because there is also a mysqld+nginx/fcgi on this machine which should be allowed to use at least 24GB together. I.e. remaining 24GB, enough for the mongod! However, it does not share in a fair way. Everybody says that the memory for mongod is managed by OS and releases unneccessary space for other processes if they demand RAM. On my machine it is not releasing RAM. What's wrong? free total used free shared buffers cached` Mem: 49559136 49403908 155228 0 57284 47247564 -/+ buffers/cache: 2099060 47460076 Swap: 8008392 164 8008228

• How create a virtual network for practice?

  - by light

  I need to organize a virtual network for practice with Windows Server 2008 and several workstations with Windows OS. To make it all I only have a laptop with Dual-Core 2.10Ghz, 3 GB RAM, 50 GB free space and Windows 7 on it. Also I have external USB 3.0 hard-drive with 250GB free space and flash disk with 8GB space. What can you suggest? Because I have limited resources, I think to install ESXi 5.1 on the main disk of my laptop as second OS, with installed Windows 7. I have no idea will it work or not, but after that I want to try to create hosts using availible space on external hard-drive. Is it possible?

• New mainboard with 890GX chipset disables lightdm, even when using old graphics card instead of onboard graphics, startx works (Xubuntu 12.04)

  - by user99250

  I am trying to migrate an installed Xubuntu 12.04 to a new mainbaord with 890GX chipset. The Chipset has a built-in Radeon HD 4290 graphics. The system boots, but X won't start. The most suspicious message in Xorg.0.log is "ddxSigGiveUp: Closing log". When searching for this message, I found some answers like "remove your xorg.conf" (but there is none on my system). Or bug reports for fglrx (but that's not installed on my system). Or NVidia-related questions ... Interestingly, "startx" succeeds in opening a basic XFCE session. Then, I tried to disable the onboard graphics in the BIOS setup and use the old PCIe graphics card (Radeon HD 5450). No change. I don't think I can just blacklist a module, because the graphics card and the onboard graphics are covered by the same module. At the moment, use the free radeon drivers, not the restricted fglrx driver. If possible, I would like to stay on the free driver for two reasons: The fglrx driver from the ubuntu packages fails to build the kernel module. In past, I had bad experiences with the fglrx driver and changing screen config with RandR. When I connect the harddisk and the graphics card to my old mainboard, everything works again. This means, I have not screwed up my system configuration wile installing and removing the fglrx drivers. When I ordered this mainboard, I thought the 890GX is old enough to be supported and if not, I could still use my graphics card as backup solution. But without even the backup soluton, I'm screwed ... Any ideas ? Thanks and Regards, Kubuntu-Man (now switched to Xubuntu)
