• XNA Per-Polygon Collision Check

  - by user22985

  I'm working on a project in XNA for WP7 with a low-poly environment, my problem is I need to setup a working per-polygon collision check between 2 or more 3d meshes. I've checked tons of tutorials but all of them use bounding-boxes, bounding-spheres,rays etc., but what I really need is a VERY precise way of checking if the polygons of two distinct models have intersected or not. If you could redirect me to an example or at least give me some pointers I would be grateful.

• Nautilus statusbar visibilty - Quickly check free space

  - by Jeremy

  In prior versions, I would open Nautilus and check the statusbar, which would tell me how much free space there is. Now, the statusbar isn't shown by default. I know you can enable it from the View menu, but 99% of users won't do that (and I'd rather not do that, if possible). So, is there some new recommended way to keep tabs on hard drive usage? Or is there maybe some other method that I should have been using in the past but never noticed?

• Hard disk with bad clusters

  - by Dan

  I have been trying to backup some files up to DVD recently, and the burn process failed saying the CRC check failed for certain files. I then tried to browse to these files in Windows explorer and my whole machine locks up and I have to reboot. I ran check disk without the '/F /R' arguments and it told me I had bad sectors. So I re-ran it with the arguments and check disk fails during the 'Chkdsk is verifying usn journal' stage with this error: Insufficient disk space to fix the usn journal $j data stream The hard disk is a 300GB Partition on a 400GB Disk, and there is 160GBs of free space on the partition. My os (Windows 7) is installed on the other partition and is running fine. Any idea how I fix this? or repair it enough to copy my files off it?

• Eclipse Check for Updates issue

  - by Nicholas Ryan Bowers

  I install Eclipse from the Software Center so it links up and will be updated with the rest of my software. Because I am developing for Android, however, I have to install the ADT Plugin within Eclipse by going to Help Install new software (or something to that effect). Now, I do understand that I can update Eclipse through the actual Ubuntu software center/system, but in order to update plugins and extensions within Eclipse, I have to go to Help Check for Updates (which then scans all plugins for updates). The only issue, is that when I installed through the software center, the owner became root, and whenever I run it without root, I'm not able to update - I get the error message "Insufficient access privileges to apply this update." When I run it as root, all of my plugins disappear, because I guess I installed them as myself, not as root. I tried to install the plugins as root, but the Install New Software choice would not work. Ubuntu 12.04 and Eclipse 3.7.2-1

• BFCM &ndash; Big Fat Check Mark

  - by onefloridacoder

  I was installing TFS on my local laptop last week and just got around to setting up my initial collection using the TFS Console tool and “Bang!”  I received a message that told me that my local database didn’t have the full-text search option installed.  I remember the option in a (long) list of options and didn’t remember fiddling with it.   Whatever the reason, if you are installing TFS Basic on your box, make sure you have that little check ticked, or you won’t get the big fat one pictured above.  I installed SQL 2008 Developer edition which worked well for what I needed so far, and just needed to run the “Add Feature” option instead of the “Repair” option.

• Oracle Service Bus duplicate message check using Coherence by Jan van Zoggel

  - by JuergenKress

  In a situation where you need some sort of duplicate message check for an Oracle Service Bus project you would need some custom code. Since the Oracle Service Bus is stateless, when it handles a proxy service call it will not know if this specific message was handled before. So there needs to be some sort of logic in your service for validating it’s a new unique message id. Read the full article here.

• BASH Scripting: Check If running with sudo/superuser, if not, dont run, return error

  - by EvilPhoenix

  This is something I've been curious about. I make a lot of small bash scripts (.sh files) to do tasks that I routinely do. Some of those tasks require everything to be ran as superuser. I've been curious: Is it possible to, within the BASH script prior to everything being run, check if the script is being run as superuser, and if not, print a message saying You must be superuser to use this script, then subsequently terminate the script itself. The other side of that is I'd like to have the script run when the user is superuser, and not generate the error. Any ideas on coding (if statements, etc.) on how to execute the aforementioned?

• Check If You Are Eligible To Try Amazon Fire TV Free for 30 days

  - by Gopinath

  Re/Code first broke the story of Amazon offering its customers to try Amazon Fire TV free for 30 days. The Amazon Fire TV costs $99 but with this offer you get a chance to try it for 30 days without paying any money. After 30 days if you are interested you can keep it with you by paying $99 otherwise you can return it to Amazon. All the costs associated with shipping to your home as well as returning back to Amazon are covered by the offer, which means it’s a real FREE offer to try! This offer is not available for everyone, but selected customers are receiving emails from Amazon. If you are interested to try free Amazon TV either you may wait to receive an offer email or click on this link to check if you are eligible. I verified it today and it says that I’m not eligible for this offer. Try your luck and all the best.

• How to check the process is already running or not

  - by TechGuru

  I want to check the particular process in already running or not. I refereed this Q&A. But I didn't get any specific solution. Following is the example that I tried: I have created abc.sh file and run this script on background, like sh abc.sh &. Now this file is running on background and I fire the ps aux | grep "abc" command. Following is the output of this command: prakash 3594 0.0 0.0 4388 820 pts/0 S+ 16:44 0:00 grep --color=auto abc After that I stop the abc.sh running script and fire the same command ps aux | grep "abc" command. But I am getting same output like: prakash 3594 0.0 0.0 4388 820 pts/0 S+ 16:44 0:00 grep --color=auto abc Is there any other way to find the process is running or not?

• Check/Monitor Amount of SQL Queries per Hour

  - by deathlock

  My website is hosted on a shared hosting and I'd like to know how much SQL queries it is using per hour. I tried to navigate through cPanel and I find nothing to check or monitor the amount of SQL queries per hour. I tried to ask my host and they said it is not possible to do manually. However I found this http://forum.powweb.com/archive/index.php/t-49937.html and another one on Stackoverflow: http://stackoverflow.com/questions/9842094/sql-how-can-i-get-the-number-of-executed-queries-per-database-or-hour-or And since this exists, I assume that it is actually possible. Problem is I can't execute that in my phpmyAdmin. Can someone here guide me through the process?

• Check connection and reconnect wifi

  - by Ruud

  I'm building a wireless photoframe. The one thing I haven't been able to figure out is how to get my wifi connection back up using a recommended method. Right now I edited /etc/network/interfaces so wlan0 is started at boot: auto wlan0 iface wlan0 inet dhcp wireless-essid ourssid This method works fine for booting. But I found that if I do not check the connection for a long time (could be a week) it might be down. So I should reconnect. What I do now to verify the connection is working is downloading a file from the server that can't be cached (http://server.ext/ping.php?randomize=123456) If I fail to retrieve the file I assume that the connection is no longer working and I run a shell script like #!/bin/bash ifconfig wlan0 up iwconfig wlan0 essid "ourssid" dhclient wlan0 And the connection comes back. But I can't find anything if this is in any way a good method. Can this be improved upon, or is this already right?

• How to Quickly Check If Your Computer Can Run a PC Game

  - by Chris Hoffman

  PC gaming isn’t quite as simple as console gaming. If you have a laptop with weak graphics hardware or an older PC, it’s important to check whether your computer can support a game before you spend your hard-earned cash. Gamers don’t have to upgrade their hardware as often as they used to. Even a gaming PC built years ago should be able to handle the newest games just fine. Laptops not build for gaming and older PCs are a different matter.

• Check for bodies within a specific circle in Box2D

  - by ltjax

  I'm trying to find positions to insert new bodies into my world. For that, I'd like to have a "free" spot where this body wouldn't overlap with anything else. So my plan was to sample "random" positions and check whether they overlap with my "potential" new body. Since my bodies are always circular, I'd need to test within a given circle. So far, the only way to use box2d for this seems to use b2World::QueryAABB around my circle and manually doing an overlap test with all the fixtures it gives me (Box2D doesn't event seem to allow me to tap into its overlapping tests?!). It seems to me like Box2D should already provide such functionality - is there a way that lets me do this without reinventing most of the wheel again?
