  • Help Decide between C#/XNA client or Java

    - by Sparkky
    The game runs on a client/server architecture currently setup for TCP, and the client code was built in AS3 to be web based. What we're running into is 3 problems for the client. AS3 has no hardware acceleration so we are having some issues with slowdown when implementing some features TCP is really frustrating for a sidescroller when you're talking with a server. I'm having a heck of a time with the interpolation/extrapolation to make everyone else look smooth while minimizing lag. I would much rather be able to use UDP and throw in something similar to the age old Quake interpolation/extrapolation. No right click I work professionally with C#, and I did all my University (almost 2 years ago) with Java. Java really appeals to me because of the compatability while C# appeals to me because I've heard so much good about XNA and I love visual studio. For a Client/Server based MMOish sidescroller in your opinion should I stick with AS3 and the TCP protocol, or should I abandon some of my audience, ramp up the graphics and hit C#, or journey back to the land of Java. Thanks :D

  • Issue with increasing the root partition from the swap

    - by user211761
    I have an issue with increase the size of my root partition. I have ElementaryOS Luna, and while installing it asked me how much space I want to use. I choosed 15 GB for it, because I want to use this as an alternative system. The issue is that after the installation was complete, I found out that my root partition is only 7 GB big, and SWAP is 8 GB which is useless cuz I have 8 GB of RAM. Now I want to shrink the swap and increase the size of my root partition, so I booted the LiveCD and used GParted. I shrinked the swap without any problems, but now I cant add that free space to any partition. I also turned Swap off. I would add a picture, but I need at least 10 reputation to post images ( Stupid ) Its also worth mentioning that in Gparted its showing my partition in a different way. I would post an image BUT I CANT, so I need to write it down. Its something like this [Pointing arrow down] /dev/sda4 Extended /dev/sda5 ntfs /dev/sda6 ext4 (Which is my main partition) /dev/sda7 linux-swap unallocated Picture:

  • Our server hosting provider asked for our root password

    - by Andreas Larsson
    I work at a company that develops and hosts a small business critical system. We have an "Elastic cloud server" from a professional hosting provider. I recently got an email from them saying that they've had some problems with their backup solution and that they needed to install a new kernel. And they wanted us to send them the root password so they could do this work. I know that the email came from them. It's not [email protected] or anything like that. I called them and asked them about this, and they were like "yep, we need the password to do this". It just seems odd to send the root password over email like this. Do I have any reason to be concerned?

  • Protecting a webpage with an authentication form

    - by Luke
    I have created an employee webpage with a lot of company info, links, etc., but I want to protect the page because it contains some confidential company information. I am running IIS7.5 on Windows Server 2008 R2, and I already have the site setup as a normal, non-protected site. I want all active directory users to have access to the site. This is not an intranet site, it is exposed to the internet. I tried setting it up using Windows Authentication, but I had problems with multiple login prompts, etc. I just want a simple form for users to enter their credentials and have access to the site, and I need it to query the AD for login. I've searched the web for a guide on this, but I can't seem to find one that fits my situation. This is not a Web App. It is just a simple html site. Does anyone have any suggestions or a link to a guide on this? Thanks so much! -LB

  • Wifi interface changes name seemingly at random

    - by ray_voelker
    I'm currently having some issues getting a wireless interface to work continuously under an install of Ubuntu 12.04.1 LTS. Some of the issues I'm experiencing include Connection will drop out after some time after it has initially worked. Interface will be a different name after a reboot. For example, wlan0 will become wlan4 when using the ifconfig -a command. Ubuntu will take a long time to boot, looking for network adapters. The purpose of this build is to function as a web kiosk in a library. The computer is supposed to boot up into a web browser, and allow for browsing of the catalog. For some reason this interface does not appear to be working as it should. Are there any explanations for some of these problems I'm having, and perhaps some solutions? The wireless card appears as this after doing an lspci ... Ralink corp. RT2561/RT61 802.11g PCI In the /etc/network/interfaces file I have the following configuration for the interface. auto wlan0 iface wlan0 inet dhcp wireless-essid UDwireless wireless-mode Managed Thanks in advance for help on this.

  • Installing raid controller forces reinstall of Windows Server 2008

    - by Tyler
    So, I've tried two different RAID controllers that have external SATA connections on my Server 2008 machine. I can install the hardware, boot into Windows, install the drivers and reboot again. No problems. However, as soon as I try to use eSATA-connected drives and reboot something happens to the Windows install and I can no longer boot into Windows. I tried repairing from the command line, and the end result is that repair console tells me I have 0 Windows installations (?). I end up having no choice but to reinstall Windows to get back on track. I must be doing something fundamentally wrong here, but I don't know what :(

  • Solutions for iOS collaborative sync (iCloud CoreData, CouchDB)?

    - by mluisbrown
    I'm developing an iOS app where one of the features will be allowing users to share and collaborate on data (e.g. lists). From everything I've read and based on the way that iCloud CoreData sync works I assume that it would not be a good fit for the following reasons, but I wanted to make sure I wasn't missing anything, as I'd prefer not to use a 3rd party syncing solution if at all possible: iCloud sync of any kind (CoreData, Document or Key / Value pairs) can only ever be between devices that use the same iCloud account, so it's designed for a single user syncing data over multiple devices. Any kind of collaborative sync (several people editing the same document / list) simultaneously would be limited to everyone have the same iCloud account. Cases of people sharing the same iCloud account is usually limited to, for example, husband and wife or similar close relationships for a small number of people. iCloud Core Data sync is for ensuring that each sync'd device has the same data. It doesn't seem to allow syncing just a subset of the data, so scenarios in which each user has their own documents and is only sharing / collaborating on a subset of them are not supported. And I'm not even mentioning the well document problems with iCloud CoreData syncing which may or may not have been resolved with iOS 7. Given the above, it would seem that CouchDB (with TouchDB) would be a better option, as it seems to support everything I need. What other options are there that people can recommend?

  • Change Keybindings (hardware to software)

    - by Daniel
    I ran a search for this, but the answers I saw were referring to something altogether different than what I'm asking for. So let me clarify: I'm not asking how to change key-combo shortcuts. I'm asking--how do you actually change what your computer thinks you did when you press a given key? An example of what I mean (and the reason I'm asking). I'm a Chrome user, and I use Windows alongside Ubuntu. I own a Lenovo Thinkpad T61p--it came with my scholarship package, and I would have shopped for a nice computer if I could have. The T61p has two buttons above the left and right arrow keys that relate to browser commands to go back and forth one page. This is extremely frustrating for me, as I use the arrow keys, and a single accidental keystroke will catch me going back a page, losing temporary data, and yelling at my stupid keyboard. At the same time, I'm the type of person who keeps way too many tabs open. Chrome doesn't let me refigure keyboard shortcuts, and the only way it allows you to switch between tabs are ctrl+tab and ctrl+shift+tab, and ctrl+page up/down. I was using Notepad++, and they had finally found the solution to both problems! The page back and forth keys functioned as tab back and forth keys. I went through quite some effort to learn how to change the keybindings in Windows. The page back and page forward keys are now the page up and page down keys, respectively, and if I hit control, they let me switch tabs easily, and rather pleasantly. And if I hit the keys by accident, no harm, no foul. Alas, I'm in Ubuntu now, and I need to go through the process again. And while I couldn't just find the answer online, like I did for Windows, I know Ubuntu has nice, supportive communities like this one, where, hopefully, somebody can tell me how to do either what I did in Windows, or directly make it so that my computer changes tabs when I hit those buttons (removing the ctrl button from the tab-changing command).

  • Keyboard glitches for some when Ctrl key is pressed

    - by user270716
    I'm having some problems with my keyboard, if I press the Ctrl key it glitches for some time. For example, if I press Ctrl and press Tab while it's still glitched the computer shuts down as if i pressed the Power On/Off button. If I press a it "presses" Alt, A and a symbol I can't remember, if I recall correctly it's a currency symbol. If I press Ctrl again it "presses" the ' key. I'm using Windows 8 Single Language 64 bits with a ABNT2 keyboard. The processor is a Intel Celeron G530 with 2 GB of RAM.

  • How to properly uninstall/reinstall Ubuntu One on Windows XP?

    - by user73303
    I had previously installed an Ubuntu One client as a test on a Windows XP machine. Now I wanted to change the account for the client to a production one but had problems changing the email address so decided to do a reinstall. Ran uninstall. Downloaded ubuntuone-3.0.2-windows-installer.exe. It downloads, goes through the unpacking/install – strangely some of the messages say updating as if it was replacing something that was already there. I do not get the setup/signin screen. There is no ubuntu% processes running. The Program files/ubuntuone directory exists with data and dist folders. The U icon is on the desktop – pointing at ubuntuone/dist/ubuntuone-control-panel-qt.exe but this does not run. Ran uninstall again, deleted Program files/ubuntuone directory, removed any ubuntu entries for registry, rebooted. Downloaded install again - exactly the same as above. How can I uninstall Ubuntu One to get a clean reinstall? Or force the install to continue after downloading/unpacking?

  • How do I get a different type of scrollbars in 12.04? [closed]

    - by Joseph Garvin
    Possible Duplicate: How do I disable overlay scrollbars? By default 12.04 uses overlay scroll bars that do not suit my taste, and every method I've found so far of disabling them makes them broken in a different way. When I was using 11.10 this wasn't a problem because I could still change the GTK theme. In 12.04, the Appearance settings only contain a few stock themes, and other than the special purpose contrast ones they all have the overlay scroll bars. If I aptitude search gtk3 | grep theme I get no results so there appears to be no packaged alternative either. Most suggestions I've seen for disabling the overlay scroll bars involve uninstalling packages or editing files as root. I want to disable them just for the current user, not for everyone on the whole box; as should be the case for any theme/display setting. There is a gsettings command that temporarily disables the overlay scrollbars just for the current user, but this has two problems of its own: The setting doesn't stick after log off. Because who would want to save settings? The scroll bars put in place have no contrast. They have a black scroller on a black background and are completely unusable. In short what I'd like to know is how to disable overlay scroll bars such that: My preference is user specific. My preference is actually saved. The scroller can actually be seen against the background without having to use a special high contrast theme that makes my whole desktop look like a negative photo from Tron.

  • Ubuntu 10.04: boot error for custom compiled kernel - gave up waiting for root device

    - by atharva
    I have installed lucid on my Lenevo Laptop (Y 410 series , x86 platform) and it is working fine. Now I have compiled kernel 2.6.37 downloaded from the kernel tree. I followed usual procedure of compiling kernel (make menuconfig, make, make modules etc). Then I created the initrd image using mkinitramfs and updated my grub using update-grub command. update-grub detects the initrd image of the compiled kernel. However when I boot from this kernel it gives me following error: Gave up waiting for root device. Common problems: -Boot args (cat /proc/cmdline) -Check rootdelay= (did the system wait long enough?) -Check root= (did the system wait for the right device?) -Missing modules (cat /proc/modules; ls /dev) ALERT! root=UUID=/... does not exist and then it falls onto initramfs prompt. I have tried following solutions discussed in different Ubuntu forums: disable uuid and point root=/dev/sda8 (sda8 is where my kernel image resides (both default kernel and compiled one) from /etc/default/grub compile kernel using CONFIG_DEVTMPFS=y suggested here Still I am unable to boot from the compile kernel. Could someone please suggest me the solution?

  • JRE not running correctly on Windows 7 64Bit

    - by dkt91
    An application called DBGL (DosBox Game Launcher) requires JRE in order to run successfully. I had it installed and running on my old Windows 7 32Bit machine without any problems. Today I got my new PC with Windows 64Bit and I cannot get it running anymore. If I install the latest JRE 32Bit version to the \Program Files (x86) folder DBGL says it needs the latest JRE version in order to run and doesn't start. If I install the latest JRE 64Bit version to the \Program Files folder I do not get an error message anymore but the application doesn't start either. Clicking it has literally no effect. Right now I have both JRE versions running parallely and I get the same result I have when only the 64Bit version is installed. Thanks in advance!

  • Users will be kicked out of a network drive (DFS)

    - by user71563
    Hi, In early January 2011, we completely switched to Windows Server 2008 R2 and Windows 7. On our domain controller set up a DFS is that the users as "Z: drive" is displayed. The DFS was it in the same way during our time with Windows Server 2003 R2 and Windows XP. At the time it has always worked without problems. Since Windows 7, we have sometimes the case that when a user accesses to the Z drive, the Explorer will return to the workplace without a user can do. After two to three trials of the Explorer remains in the network drive and the users work. This phenomenon occurs irregularly and you can not restrict exactly why. In the event log at the time no obvious entries are logged. Does anyone know the problem or has had similar experiences? I am grateful for any help. Greetings, sY!v3Rs

  • Permission denied on network share

    - by Philipp
    i have a Windows 8 host system running a virtual(hyper-v) Debian6 client with an lamp environment. My development environment runs under Windows and I mapped the folder with my php files to a network drive so Apache has access to them.(mount.cifs //pc/share /var/share/) This far no problems - I see my app on windows in the browser. The problem is, I can't write stuff in php to the share folder - everytime i got a permission denied message in my error logs. For testing purpose i tried to change the directory permissions of /var/share with chmod -R 777 /var/share without success. Now Iam a little bit stumped.. has anyone an idea how to solve this?

  • Change the Log Level of Node Manager.

    - by adejuanc
    This is useful to troubleshoot issues related to Node Manager, such as problems starting a Managed Server or reasons a server could be (re)started. To change the Log Level of Node Manager, you need to edit the nodemanager.properties file. This is usually located at: <MIDDLEWARE_HOME>/wlserver_10.3/common/nodemanager What you need to modify is property: ...LogLevel=INFO... Information about the appropriate values for this property is available in the Node Manager Documentation at 10.3 WebLogic Documentation (and in further releases) which states: LogLevel: Severity level of logging used for the Node Manager log. Node Manager uses the same logging levels as WebLogic Server. Default value: INFO However, this is incorrect. WLS has its own implementation of LogLevel, but Node Manager uses the standard Log Level from the java.util.logging.Level class. Therefore, the possible values for Node Manager LogLevel, in descending order are: SEVERE (highest value) WARNING INFO CONFIG FINE FINER FINEST (lowest value) The highest value provides only messages at the severe level. The warning level provides warning messages and severe messages, and so on. Besides those levels, ALL and OFF are also accepted. For example, if you only want Severe messages to be logged, select SEVERE. If you need the most detailed tracing available, select FINEST. For more information on what it will log at each level, please read the Java SE API for LoggingLevel.

  • Testing my model for hybrid scheduling in Embedded Systems

    - by markusian
    I am working on a project for school, where I have to analyze the performances of a few fixed-priority servers algorithms (polling server, deferrable server, priority exchange) using a simulator in the case of hybrid scheduling, where we have both hard periodic tasks and soft aperiodic tasks. In my model I consider that: the hard tasks have a period equal to their deadline, with a known worst case execution time (wcet). The actual execution time could be smaller than the wcet. the soft tasks have a known wcet and random interarrival times. The actual execution time could be smaller than the wcet. In order to test those algorithms I need realistic case studies. For this reason I'm digging in the scientific literature but I am facing different problems: Sometimes I find a list of hard tasks with wcet, but it is not specified how the soft tasks parameters are found. Given the wcet of a task, how can I model its actual execution time? This means, what random distribution should I use considering the wcet? How can I model the random interarrival times of soft aperiodic tasks?

  • Where can I find a link to download the SP2 of OES2?

    - by Philippe
    Hi, I have a Netware Novell server with an eDirectory and different objects configured. I implemented an OEServer2 SP1 to emulate a DSfW to manage the eDirectory with AD. I join the domain with the Administrator login and I am logged as the Administrator domain. So far, there are no problems. When I open the MMC window on Windows Server 08 and snap in the "Active Directory Users and Computers" I can see all the OUs and objects presented in the Netware N. server. But, when I select some OUs I can have an error, and when I select other I don’t have this error. Error: “Data from XXXXX is not available from Domain Controller OES2.yyyy.local because: The server is unwilling to process the request. Try again later, or choose another DC by selecting Connect to Domain Controller on the Domain context menu.” With XXXX= OU’s name and yyyy.local= domain name and OES2 server name If somebody can upload this SP or post a link to download it... Thank you for your help!

  • Can I make Firefox ignore/interpret font sizes specified in pixels?

    - by Andy
    Hi all, I have an 11.1" notebook display with 1366x768 resolution, which gives it a DPI of 141. I'm running GNOME and have configured the DPI. Everything works OK except web browsing - far too many websites specify their font sizes in pixels, which ends up with very small text on a high DPI display. My ideal solution would be for Firefox to interpret an absolute pixel size in terms of normal DPI and display it appropriately for my DPI (eg scale it by 141/96). Obviously this would cause problems on the occasion where graphics had been pixel-aligned with fonts in some way, but I imagine that would cause me far less of a headache than either reading minute text, or scaling the text manually each time. Any suggestions? TIA, Andy

  • Lots of Internet browsing issues, all browsers

    - by dario_ramos
    Before the upgrade, everything was working fine. Now, however, I can connect to the Internet but a lot of stuff fails, and the weirdest thing is that it happens with Firefox, Chromium and Opera. Some of the things that fail: I can't log in to Stack Overflow, after entering user/pass it loads for a long time on Firefox and throws Error 408 (browser request timed out) on Chromium and Opera I can't log in to Hotmail, similar symptoms I can login to Facebook, but when I try to write a comment, or just post something in my wall, it stays loading for a long time, and then fails The first two issues seem to be related to secure pages, and the second one is another issue altogether, I believe. However, they all happen with all browsers, which is really weird. Talking about weird: I connect using a Huawei SmartAX MT 810 USB modem, which cost me blood and tears to get it working under Ubuntu. I ordered an ethernet modem/router with my ISP, and I'm still waiting, but this issue intrigues me anyway. Has anyone experienced this kind of problems? I Googled around, but couldn't find a similar case.

  • Why would he say "We don't want to support MVC3"?

    - by MadBurn
    I work in a small shop at a fairly big company doing intranet web applications. By small, I mean there is 1 other guy in my position... and he graduated with me last December. (we aren't the only IT, but the only ones in our field) We are switching out an old COBOL system and converting it's only used application suite to a Web App. My company has contracted to a Web Application firm to help with this process who has chosen ASP.NET MVC, during one of the important meetings I asked if they will be using MVC2 or MVC3. Their lead developer said: "MVC2, we don't want to support MVC3. haha" My question is, why is this? This was several months ago and I've been doing extensive and self training gearing up for the MVC switch. From everything I am understanding, MVC3 is just like MVC2 if you don't use Razor and it fixes a number of smaller bugs that MVC2 had. So in my eyes, I can't see any reason to NOT use MCV3. There has to be something I'm missing. Since I don't really have any mentors to turn to in the real world, I'm coming here. What problems are there with MVC3 that might possibly lead him to say this that I'm missing?

  • Client PC not booting when certain TFT plugged in - TFT or graphics card failure?

    - by Chake
    here comes something quite strange: On a client machine (DELL Vostro 420) we experienced problems when booting: when turning on the machine beeps normal but doesn't display anything and doesn't boot. After some testing I found out, that this only happens if one (of the two) monitors (Iiyama ProLite E2472HDD) is plugged in while booting. If the other monitor (TFT 2) is plugged in everything is fine. Here a small illustration, TFT 1 is the bad guy: TFT 1 | TFT 2 | failure x | x | x x | | x | x | After BIOS-Phase I can safely plug in TFT 1 and everything works just fine. The question is, what can be done to avoide this behavior: Change monitor? (Iiyama ProLite E2472HDD) Change graphics card? (GeForce 9800 GT) Other suggestions?
