  • Why are 3D game scenarios so big? and.. are them shareable? [closed]

    - by Néstor Sánchez A.
    First, I apologize if this is not the forum for these type of questions. I was wondering... 1- Why 3D games (such as GTA IV) uses so much gigabytes of space? And my half-answar was... because of their huge 3D scenarios. But wait! are not these scenarios made with vector graphics and textures? then.. why are so big??? 2- If they are so big... would really these companies make a whole new scenario for every new game they develop? that would be very inefficient. Doesn't exist "shareable" scenarios that can be used in different games and expanded to no rebuild a whole one (like "New York" or "Liberty City")???. I mean.. the scenarios is almost the same in terms of vertices, just with improved textures.

  • Why can't I link my Skype contacts with the rest in Empathy?

    - by Arturo Torres Sánchez
    I'm using Skype in Empathy thanks to telepathy-haze and pidgin-skype. I've also added MSN, Jabber (Gtalk), and Facebook. When I link contacts from MSN, Gtalk, and Facebook, there's no problem, but if I include a Skype contact, either nothing happens or Empathy crashes and after restarting I see that the Skype contact was never linked. Is the fact that Skype is not natively supported in Telepathy a problem for linking?

  • Out of memory on MATLAB

    - by Eric Sánchez
    I'm trying to run a script on matlab_2011a, which calculate same means for a climatology of 50 years. When I started to run the script for all the years it worked fine until the iteration 20th, and then appeared the message: Out of memory. Type HELP MEMORY for your options. Then I used clear v1 v2 v3 ... to clear all the variables inside the function, also i used clear train because i saw it in another forum, and these with the modifications or not, I run again the script (since the 21th iteration), and the result is the same message, but curiously sometimes it run a year and then stop. Any ideas about solving this problem?, what I have to clean to run correctly? (in this matlab version there's not the command memory which maybe could help me).

  • Why sometimes Windows cannot kill a process?

    - by Néstor Sánchez A.
    Right now I'm trying to Run/Debung my app on VisualStudio, but it cannot create it because the las instance of the app.vshost.exe is still running. Then, by using the Task Manager i'm trying to kill it, but it just remains there with no signal of activity. Beyond that particular case (maybe a VS bug), i'm very curious about the technical reasons why sometimes Windows cannot kill a process??? Can, an enlighted OS related developer, please try to explain? (And please don't start a Unix/Linux/Mac battle against Windows)

  • How can I limit the upload/download bandwidth on my CentOS server?

    - by Dan Nestor
    How can I limit the upload and download bandwidth on my CentOS server? This is a box with a single interface, eth0. Ideally, I would like a command-line solution (I've been trying to use tc), something that I could easily switch on and off in a script. So far I've been trying to do something like tc filter add dev eth0 protocol ip prio 50 u32 police rate 100kbit burst 10240 drop but I'm obviously missing a lot of knowledge and information. Can somebody help with a quick one-liner? Many thanks, Dan

  • Installing Numpy locally

    - by Néstor
    I posted this question originally on StackOverflow, but a user suggested I moved it here so here I go! I have an account in a remote computer without root permissions and I needed to install a local version of Python (the remote computer has a version of Python that is incompatible with some codes I have), Numpy and Scipy there. I've been trying to install numpy locally since yesterday, with no success. I successfully installed a local version of Python (2.7.3) in /home/myusername/.local/, so I access to this version of Python by doing /home/myusername/.local/bin/python. I tried two ways of installing Numpy: I downloaded the lastest stable version of Numpy from the official webpage, unpacked it, got into the unpacked folder and did: /home/myusername/.local/bin/python setup.py install --prefix=/home/myusername/.local. However, I get the following error, which is followed by a series of other errors (deriving from this one): gcc -pthread -shared build/temp.linux-x86_64-2.7/numpy/core/blasdot/_dotblas.o -L/usr/local/lib -Lbuild/temp.linux-x86_64-2.7 -lptf77blas -lptcblas -latlas -o build/lib.linux-x86_64-2.7/numpy/core/_dotblas.so /usr/bin/ld: /usr/local/lib/libptcblas.a(cblas_dptgemm.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC Not really knowing what this meant (except that the error apparently has to do with the LAPACK library), I just did the same command as above, but now putting LDFLAGS='-fPIC', as suggested by the error i.e., I did LDFLAGS="-fPIC" /home/myusername/.local/bin/python setup.py install --prefix=/home/myusername/.local. However, I got the same error (except that the prefix -fPIC was addeded after the gcc command above). I tried installing it using pip, i.e., doing /home/myusername/.local/bin/pip install numpy /after successfully instaling pip in my local path). However, I get the exact same error. I searched on the web, but none of the errors seemed to be similar to mine. My first guess is that this has to do with some piece of code that needs root permissions to be executed, or maybe with some problem with the version of the LAPACK libraries or with gcc (gcc version 4.1.2 is installed on the remote computer). Help, anyone?

  • Can I enable discards on a LUKS-encrypted ssd drive in RHEL6 (and do I need to)?

    - by Dan Nestor
    I have a RHEL 6.4 workstation, running on a LUKS-encrypted LV residing on a SSD. I found RedHat documentation stating that dm_crypt does not currently support TRIM passthrough, however I also found other sources that state the opposite (albeit for other distributions) and even that discards are not needed for recent SSD drives which use some sort of automatic garbage collection. So: 1) Can I enable TRIM/discards with my setup? 2) Do I need to, for optimal disk performance? Thanks for your thoughts.

  • What's the issue with this Samba setup?

    - by Dan Nestor
    I asked this on superuser, but I realized that may be the wrong place. I am duplicating the question here, I hope this is allowed. I am trying to share a directory through samba. In smb.conf I have the following: [global] workgroup = WORKGROUP security = user passdb backend = tdbsam netbios name = <hostname> [share_name] path = </path/to/share> writable = yes valid users = <username> <username>, the user in question, is the owner of directory /path/to/share. Permissions on the directory are 755. If I try to connect from another computer, the connection attempt is unsuccessful (I assume it's an authentication error, because it re-prompts me for the password). The client requires a domain name for authentication, I tried both WORKGROUP and the hostname/netbios name of the samba server. Samba logs on the server have no mention of the failed connection attempt. Firewall on the server is down. What am I doing wrong? Update: have since run smbpasswd -a <username> and now I am getting a clear error message, "not enough permissions to view contents of share".

  • how to disable RemoteApp sessions lock if idle for 10 minutes and require no user needs to input password to unlock?

    - by Carlos Sanchez
    RemoteApp sessions lock if idle for 10 minutes, user needs to input password to unlock. My users are running an application from Win2008 Terminal server using RemoteApp. If the application remains idle for 10 minutes it gets "locked" and the user is required to enter username and password to continue using it. This is VERY VERY annoying as the app usually sits idle for bout 20-30 minutes, used for 1 min... repeat.

  • Can't ping other machines at Linux VPN PPTP server's local lan from outside

    - by Marco Sanchez
    Before anything else, hello guys, this is the first time I ask for something here so I hope someone can give me a hand, please look at the following network diagram: --------------------------------------------------------------- VPN Server Webserver (SuSE SLES11) | | | ------- VPN LAN -------- | Router with Unique IP (With Port Forwarding rules set and VPN through enabled) | PPTP connection over Internet | Workstation (PC or Laptop with Windows) --------------------------------------------------------------- So the idea is for the workstation to connect to the PPTP Server and then be able to access a Web Application on the Webserver, right now I have the PPTP server configured and the VPN works, I can connect to the SLES11 server with no problems from the workstation and I can ping it and everything works fine but if I try to ping the Webserver from the workstation, I can't reach it, I'm making a mistake somewhere but I don't see where, please note that I'm not a network expert and thus I'd greatly appreciate some specific guidance. Here is some info related to the IPs --------------------------------------------------------------- *** SLES11 VPN Server has 2 Network cards: -- eth0 (Internal Network) IP: 192.168.210.5 MASK: 255.55.255.0 -- eth1 (External Network) IP: 192.168.1.105 MASK: 255.55.255.0 *** Webserver has 1 network card -- eth0 (Internal Network) IP: 192.168.210.221 MASK: 255.55.255.0 *** Workstation -- IP info once connection has been established to the VPN PPP adapter Test VPN Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Test VPN Connection Physical Address. . . . . . . . . : DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 192.168.210.110(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : 0.0.0.0 DNS Servers . . . . . . . . . . . : 189.209.208.181 (Defined as part of the PPTP Server options config script) 189.209.127.244 Primary WINS Server . . . . . . . : 192.168.210.220 (Defined as part of the PPTP Server options config script) NetBIOS over Tcpip. . . . . . . . : Enabled --------------------------------------------------------------- I also defined the following within IP tables: ------------------------------------------------------------- iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE iptables -A INPUT -i eth0 -p tcp --dport 1723 -j ACCEPT iptables -A INPUT -i eth0 -p gre -j ACCEPT ------------------------------------------------------------- If you need any piece of information from the PPTP server scripts please let me know, the thing is that I can actually connect to the VPN server and access its services and everything but after that I can't reach any other computer on that LAN. Any help would be greatly appreciated and thanks in advance

  • Connecting to unsecured wireless network

    - by Sanchez
    I would like to know what information is public and can be intercepted in a non-open, but unsecured wireless network. Moreover, is there anything I can do to make it more "secure", other than using https connection whenever possible. In more details, I recently discovered (with surprise) that the wireless network in my school is actually unsecured. Although not everyone can connect to it (you need a student ID), I am told that certain softwares like Wireshark would be able to intercept the data. Since I have been using the network for all private purposes (email, facebook etc), I do feel quite insecure now and would like to understand the situation a bit better. I installed Wireshark and tried to play with it but all I can see are something alien to me. In any case, all I see seems to come directly/indirectly from my IP address, and I have long thought that usually different computers in the same wireless network would be assigned different addresses. Am I wrong? If not, then I feel very confused about what information is actually being captured (potentially by other users in the network, since I don't think I could capture activities of others in the same network anyway), and whether it's safe to use the network at all. (Gambling on others in the same network showing good behaviour is apparently not an option.) Thank you.

  • What is the most simple implementation of IDynamicMetaObjectProvider?

    - by Néstor Sánchez A.
    Hi, I have this scenario... 1.- I'm providing a "Dynamic Table" for wich users can define Fields. Each Dynamic Table will have as many rows/records as needed, but the Field definitions are centralized. 2.- My Dynamic Row/Record class was inherited from the .NET DLR DynamicObject class, and the underlying storage was a List appropriately associated to the defining fields. Everything works fine! BUT... 3.- Because I need to Serialize the content, and DynamicObject is not Serializable, I was forced to generate and carry a Dynamic Object when dynamic member access is required. But this is ugly and redundant. So, I need to implement IDynamicMetaObjectProvider myself to achieve dynamic access and serialization together. After googling/binging unsuccessfully I ask for your help... Can anybody please give a good example (or related link) for doing that?

  • How to Serialize a WPF Drawing?

    - by Néstor Sánchez A.
    Hi, maybe I'm missing something. I believed that WPF vector-based Drawings (like DrawingGroup, DrawingGeometry, etc.) were ready to be serialized. But they are not. So, should I navigate all these drawing childrens, and store they points, lines, brushes (that also are not serializable) and so on, and then made my custom serialization? Is really that difficult or I'm missing something pretty obvious? I mean, even serializing Bitmap images is easy. I thinked serializing vector-based drawings were easier (no quality loss, just descriptive info, no massive data). Thanks for your practical answers, alternate-way suggestions and comments!

  • How to program asynchronous Windows Forms Applications?

    - by Nestor
    I'm writting a Windows Forms application in C# that performs a lot of long-running procedures. I need to program the application so that the GUI doesn't lock. What is the best way to program it? I know how to use the following: BeginInvoke/EndInvoke Calling Application.DoEvents() repeatedly (probably not a good idea) BackgroundWorker etc. But how to manage GUI state with call backs, etc... is not trivial. Are there solutions for this (in the form of patterns or libraries)?
