  • Did You Know? What settings to always change

    - by Kalen Delaney
    A week ago, I taught my SQL Server 2012 Internals class to a great group of very interactive students. Even though a dozen of them were taking the class remotely, there were still lots of really great questions and and lots of discussion. One of the students asked if I could summarize all the settings that I recommended changing from the default, right out of the box. I said I’d try to put a list together by the end of the week, but I didn’t make it. So I said I would put it together and blog it....(read more)

  • Dynamic Memory Allocation and Memory Management

    - by Bunkai.Satori
    In an average game, there are hundreds or maybe thousands of objects in the scene. Is it completely correct to allocate memory for all objects, including gun shots (bullets), dynamically via default new()? Should I create any memory pool for dynamic allocation, or is there no need to bother with this? What if the target platform are mobile devices? Is there a need for a memory manager in a mobile game, please? Thank you. Language Used: C++; Currently developed under Windows, but planned to be ported later.

  • Port listening on localhost:8000 but not on ip:8000

    - by Marionette
    Hello I'm running a web application on port 8000. When I access it from the host server localhost:8000 it responds ok, 127.0.0.1:8000 also works, but 192.168.1.7:8000 does not work. 192.168.1.7 is the ip of my server. Also if i try to go to another web application running on port 80 it works 192.168.1.7 I enabled ufw firewall and set ufw default allow. I am using ubuntu server 12.04 Any suggestions on why I can't get to my app on port 8000 using the ip-address:8000? Thanks in advance!

  • assigning values to shader parameters in the XNA content pipeline

    - by Nick
    I have tried creating a simple content processor that assigns the custom effect I created to models instead of the default BasicEffect. [ContentProcessor(DisplayName = "Shadow Mapping Model")] public class ShadowMappingModelProcessor : ModelProcessor { protected override MaterialContent ConvertMaterial(MaterialContent material, ContentProcessorContext context) { EffectMaterialContent shadowMappingMaterial = new EffectMaterialContent(); shadowMappingMaterial.Effect = new ExternalReference<EffectContent>("Effects/MultipassShadowMapping.fx"); return context.Convert<MaterialContent, MaterialContent>(shadowMappingMaterial, typeof(MaterialProcessor).Name); } } This works, but when I go to draw a model in a game, the effect has no material properties assigned. How would I go about assigning, say, my DiffuseColor or SpecularColor shader parameter to white or (better) can I assign it to some value specified by the artist in the model? (I think this may have something to do with the OpaqueDataDictionary but I am confused on how to use it--the content pipeline has always been a black box to me.)

  • Blender Object Appearing Gray when all Lights are Off

    - by celestialorb
    I have an issue with Blender where, when I turn my only light off (a sun lamp) and render the image my object appears gray rather than black (and thus, not appear to the camera). I can't figure out why this is happening. Here's what I just did in my scene: Added a new UV Sphere mesh (to make a total of two spheres), made it visible to the camera, turned off the sun lamp (by setting energy to 0), and rendered. The result I obtained is below. I discovered this when attempting to render the first sphere with a material/texture on it and it was too bright. The material on the spheres (which are different) are very basic, there's no emit, diffuse and specular are at default values. Could there be an issue with the way my camera is setup? Thanks in advance!

  • Quickly and Automatically Restart a Windows Program When it Crashes

    - by Lori Kaufman
    We’ve all had programs crash on us in Windows at one time or another. You can take the time to manually start the program again, or you can have a simple program like ReStartMe restart it automatically for you. ReStartMe is a free program that has one purpose in life, to restart processes. You tell it to watch specific processes and if any of those processes exit, whether they crashed or you accidentally closed them, ReStartMe will automatically restart them. To install the program, double-click on the restartmeinstaller.exe file you downloaded (see the link at the end of the article). Follow the easy installation process, accepting the default settings.

  • Mount drives at `/drivename` from nautilus

    - by Anwar Shah
    I want to mount my other drives (mostly ntfs and fat) on /drivename by clicking on the drive icon in the nautilus side pane, where "drivename" refers to the label of the drive. By default nautilus (actually the udisks program) mounts drives in /media/ folder with drive name. How can I achieve this?. Note: Please do not suggest doing this by editing /etc/fstab file. I want this feature in nautilus and after clicking the drive should also be seen in the side pane. (should not be hidden). Edit: Seems to be some have misunderstood this. I don't want to mount in / but as /Main, where "Main" is the label of my ntfs partition. To make it clear, suppose I have two partitions named as "Work" and "Main". I want them to mount at /Work and /Main respectively, when clicked on their icon in nautilus

  • Deleted some files from home folder

    - by narendra shah
    I have recently installed Ubuntu for the first time in my life. So I am fairly new to it. I have deleted some files from my home folder. But now the problems have started. The system volume automatically reduces to zero. Further, as soon as I restarted my system, my panel settings we restored to default. When I right click in my home folder, it gives an option of 'restore missing files' but I am not able to restore them. Please guide me how to restore them. Thanks Narendra

  • Audiencing with Forms-Based Authentication (FBA)

    - by PeterBrunone
    This really is no different from when you create an audience with regular old NTLM (Windows Authentication).  The difference is that while the AD provider is set up by default in all environments, the extra membership provider (that you use for Forms Authentication) isn't included anywhere except in the web application where you install it.  To be able to find your FBA users in the audience creation tool, you'll need to add the extra membership provider(s) to the web.config for your SSP site in IIS.  At that point, the People Picker should start recognizing your Forms Auth users, and you can create your audience as needed.

  • How to Create AppArmor Profiles to Lock Down Programs on Ubuntu

    - by Chris Hoffman
    AppArmor locks down programs on your Ubuntu system, allowing them only the permissions they require in normal use – particularly useful for server software that may become compromised. AppArmor includes simple tools you can use to lock down other applications. AppArmor is included by default in Ubuntu and some other Linux distributions. Ubuntu ships AppArmor with several profiles, but you can also create your own AppArmor profiles. AppArmor’s utilities can monitor a program’s execution and help you create a profile. Before creating your own profile for an application, you may want to check the apparmor-profiles package in Ubuntu’s repositories to see if a profile for the application you want to confine already exists.

  • How to open OLE2 file format document

    - by Dominic Jordan Hasford
    I received a file that is .OLE2 format by email and I can't get it open. When I try to open it with Document Viewer (default pfd program ubuntu) it says it can't support it. I searched in the Software Center for OLE2, and it returned a program called RipOle. It says it opens that format, but you have to run it in the terminal and I don't know how. Does any one know how to open OLE2 documents? Or do you know how to work ripole? Thanks in advanced!

  • How to make bash quit tab autocompleting hidden directories

    - by Kristopher Micinski
    Most of the time, I don't need autocompletes for my hidden directories. In fact, that's the point of them being hidden! However, annoyingly, bash takes these directories into account when considering tab autocompletion. This is particularly annoying when I have the following scenario: a .svn foler along with a single folder that I want to traverse into by simply pushing tab. (This typically comes up with deep Java packages...) Is there any way to change the default behavior? Worst case scenario I have to type '.' before tab, which seems like a no brainer for my usability.

  • Central Exception Handler

    - by J-unior
    Recently I've been thinking about a general ExceptionHandler, that I could initialize once in my app context and inject it everywhere. The idea that it will have quite simple interface with just public void handle(Exception ex), and then according to exception type it should decide what to do, maybe just log it, or show an alert message to the user, or maybe kill the whole app. The question is, what is the prettiest way to write such handler without lots of instanceofs? Unfortunately googling gives me only the default exception handler for RuntimeException that was introduced in Java 5. My first idea is to create an enum, that will have Class field for exception type and it will return the appropriate execution point, for example a concrete exception handler that also implements the interface public void handle(Exception ex), but with the required casting already.

  • Bluetooth fix for Ubuntu 12.04, lenovo G580

    - by Sam Abraham
    Bluetooth not working, it shows turned on but manager indicated Bluetooth disabled. Uninstalled default manager and installed Blueman. The same with Blueman, clicking on connect to devices gets response 'adapters not found'. I've found many more people with the same problem. The fixes found in the archive don't work for me. I've tried a couple of things from the forum. I'm not familiar with computer hardware or software but have been using Ubuntu cause it saves me money, it's fairly easy to use and it does not tax my mid-range lap. Any help will be appreciated.

  • Firefox 4 stores passwords, but suddenly forgot that it did?

    - by Roland Taylor
    I am using firefox 4 as my default browser, but this is probably file system related. I will describe the problem and hopefully someone can point me in the right direction? Today I was using the browser as normal, all sign ins worked as usual, everything was normal. Then when I got back home tonight and opened it, none of my saved usernames/passwords would autofill/auto-signin anymore. I am guessing this must be something filesystem related, and it only happened this one time seemingly at random, so I don't think it is a firefox 4 bug. In fact, I think it might be something to do with suspending the system before I left? Anyone have any idea?

  • 3 Ways to Make Steam Even Faster

    - by Chris Hoffman
    Have you ever noticed how slow Steam’s built-in web browser can be? Do you struggle with slow download speeds? Or is Steam just slow in general? These tips will help you speed it up. Steam isn’t a game itself, so there are no 3D settings to change to achieve maximum performance. But there are some things you can do to speed it up dramatically. Speed Up the Steam Web Browser Steam’s built-in web browser — used in both the Steam store and in Steam’s in-game overlay to provide a web browser you can quickly use within games – can be frustratingly slow on many systems. Rather than the typical speed we’ve come to expect from Chrome, Firefox, or even Internet Explorer, Steam seems to struggle. When you click a link or go to a new page, there’s a noticeable delay before the new page appears — something that doesn’t happen in desktop browsers. Many people seem to have made peace with this slowness, accepting that Steam’s built-in browser is just bad. However, there’s a trick that will eliminate this delay on many systems and make the Steam web browser fast. This problem seems to arise from an incompatibility with the Automatically Detect Proxy Settings option, which is enabled by default on Windows. This is a compatibility option that very few people should actually need, so it’s safe to disable it. To disable this option, open the Internet Options dialog — press the Windows key to access the Start menu or Start screen, type Internet Options, and click the Internet Options shortcut. Select the Connections tab in the Internet Options window and click the LAN settings button. Uncheck the Automatically detect settings option here, then click OK to save your settings. If you experienced a significant delay every time a web page loaded in Steam’s web browser, it should now be gone. In the unlikely event that you encounter some sort of problem with your network connection, you could always re-enable this option. Increase Steam’s Game Download Speed Steam attempts to automatically select the nearest download server to your location. However, it may not always select the ideal download server. Or, in the case of high-traffic events like big seasonal sales and huge game launches, you may benefit from selecting a less-congested server. To do this, open Steam’s settings by clicking the Steam menu in Steam and selecting Settings. Click over to the Downloads tab and select the closest download server from the Download Region box. You should also ensure that Steam’s download bandwidth isn’t limited from here. You may want to restart Steam and see if your download speeds improve after changing this setting. In some cases, the closest server might not be the fastest. One a bit farther away could be faster if your local server is more congested, for example. Steam once provided information about content server load, which allowed you to select a regional server that wasn’t under high-load, but this information no longer seems to be available. Steam still provides a page that shows you the amount of download activity happening in different regions, including statistics about the difference in download speeds in different US states, but this information isn’t as useful. Accelerate Steam and Your Games One way to speed up all your games — and Steam itself —  is by getting a solid-state drive and installing Steam to it. Steam allows you to easily move your Steam folder — at C:\Program Files (x86)\Steam by default — to another hard drive. Just move it like you would any other folder. You can then launch the Steam.exe program as if you had never moved Steam’s files. Steam also allows you to configure multiple game library folders. This means that you can set up a Steam library folder on a solid-state drive and one on your larger magnetic hard drive. Install your most frequently played games to the solid-state drive for maximum speed and your less frequently played ones to the slower magnetic hard drive to save SSD space. To set up additional library folders, open Steam’s Settings window and click the Downloads tab. You’ll find the Steam Library Folders option here. Click the Add Library Folder button and create a new game library on another hard drive. When you install a game in Steam, you’ll be asked which library folder you want to install it to. With the proxy compatibility option disabled, the correct download server chosen, and Steam installed to a fast SSD, it should be a speed demon. There’s not much more you can do to speed up Steam, short of upgrading other hardware like your computer’s CPU. Image Credit: Andrew Nash on Flickr

  • How do I point a new domain to start on a page that's not index.html on separate hosting? [closed]

    - by Owen Campbell-Moore
    Possible Duplicate: How do I point a new domain to start on a page that's not index.html on separate hosting? I'm using a service called SquareSpace to host my site, and today I'm registering the domain for it. Basically, how do I make it so when somebody types www.tedxoxford.com it points at http://www.tedxoxford.com/landing (currently http://tedxoxford.squarespace.com/landing) instead of the default index? Is this possible? Squarespace is quite a restricted CMS and means that your logos etc all point to the index so I don't want people ending up on my landing/splash page every time they want the home page, only on the first time they type in the URL. A dirty hack would be to check the refferer and redirect anyone hitting the index to the landing page, but that's a lot of loading overhead I'd rather avoid...

  • How to open a file or folder from Terminal

    - by Victor Hugo Souza
    I'd like to know if there is a way to open a file or a folder from terminal? When I wrote a URL LINK in terminal, it's allows me to open that link on my default browser. So I'd like to do the same with my files and folders. I know that there is a way via cli using gnome-open or xdg-open, but I'd like a solution that use mouse by clicking on the path or the url. Eg. When I write "pwd" the path allows me to click and open on Nautilus It's the inverse of what "nautilus-open-terminal" does.

It creates a bridge with eth0 and wlan0 and starts hostapd. #!/bin/bash service network-manager stop ifconfig eth0 0.0.0.0 #remove IP from eth0 ifconfig eth0 up #ensure the interface is up ifconfig wlan0 0.0.0.0 #remove IP from eth1 ifconfig wlan0 up #ensure the interface is up brctl addbr br0 #create br0 node hostapd -d /etc/hostapd/hostapd.conf > /var/log/hostapd.log & sleep 5 brctl addif br0 eth0 #add eth0 to bridge br0 brctl addif br0 wlan0 #add wlan0 to bridge br0 ifconfig br0 192.168.1.15 netmask 255.255.255.0 #ip for bridge ifconfig br0 up #bring up interface route add default gw 192.168.1.1 # gateway This script works efficiently. But if I want to revert back to use Network Manager, I cannot do it. The bridge simply cannot be deleted. How can I modify this script so that if I run bridge_script --stop, the bridge gets deleted, network manager starts and interfaces behave as if the machine had a fresh reboot.

  • Flash 10.2 RC + Crystal HD for HW accelerated video on Ubuntu

    - by Gee
    I have a netbook with a N450 Atom and a BCM70012 aka Crystal HD card. On Windows 7 I can play HD flash video with very little CPU usage because of the RC of Flash 10.2. I did some reading and saw posts claiming that the Crystal HD card is finally supported by the newer Flash 10.2 RC in Ubuntu but I can't get it to work. I can confirm that flash 10.2 is loaded and used, and there's even a HW acceleration option that is enabled in the settings but performance is horrible. From what I read, the Crystal HD card is supposed to be enabled on 10.10 by default - I don't know if it is. I tried installing drivers for it in various ways but HD flash video is still a slideshow So does anyone have it working? If so, how'd you set it up?

  • How can I reorient the axes of an object?

    - by d3vid
    I spent some time in Unity yesterday trying to fire a sphere from a horizontal cylinder (like a ball from a cannon). I was using Vector3.forward, but the sphere kept coming out the top of the cylinder rather than the front. Someone suggested using Vector3.up instead, and sure enough it worked! The cylinder is vertical by default. So, it appears that when I rotated the cylinder by 90 degrees to lay it flat, the local axes remained the same. The relative front of the cylinder remained at the same point, so when I fired the sphere it shot out the new "top", not what looked to me like the "front". If I had happened to be facing the other way, I would have had to fire at Vector3.down instead. How can I reorient/reset the axes of an object so that they match my expectations? (And if I can't, how can I tell by looking which way an object is oriented?)
