  • Collision in PyGame for spinning rectangular object.touching circles

    - by OverAchiever
    I'm creating a variation of Pong. One of the differences is that I use a rectangular structure as the object which is being bounced around, and I use circles as paddles. So far, all the collision handling I've worked with was using simple math (I wasn't using the collision "feature" in PyGame). The game is contained within a 2-dimensional continuous space. The idea is that the rectangular structure will spin at different speed depending on how far from the center you touch it with the circle. Also, any extremity of the rectangular structure should be able to touch any extremity of the circle. So I need to keep track of where it has been touched on both the circle and the rectangle to figure out the direction it will be bounced to. I intend to have basically 8 possible directions (Up, down, left, right and the half points between each one of those). I can work out the calculation of how the objected will be dislocated once I get the direction it will be dislocated to based on where it has been touch. I also need to keep track of where it has been touched to decide if the rectangular structure will spin clockwise or counter-clockwise after it collided. Before I started coding, I read the resources available at the PyGame website on the collision class they have (And its respective functions). I tried to work out the logic of what I was trying to achieve based on those resources and how the game will function. The only thing I could figure out that I could do was to make each one of these objects as a group of rectangular objects, and depending on which rectangle was touched the other would behave accordingly and give the illusion it is a single object. However, not only I don't know if this will work, but I also don't know if it is gonna look convincing based on how PyGame redraws the objects. Is there a way I can use PyGame to handle these collision detections by still having a single object? Can I figure out the point of collision on both objects using functions within PyGame precisely enough to achieve what I'm looking for? P.s: I hope the question was specific and clear enough. I apologize if there were any grammar mistakes, English is not my native language.

  • Sharing internet connection with WDS

    - by cornjuliox
    Is it possible to share an internet connection through WDS? I'm on the very edge of a wireless network, the spot that I'm in maintains a stable 22% according to XP with the help of a parabolic reflector crafted from a cheap pie tin. I was thinking I could grab another wireless router, use WDS to bridge the this router with the other one and share the 'net connection through it thus giving me a little bit more freedom but when I tried it it didn't work. WDS looks like it bridged the networks just fine, but I couldn't access anything on the internet. Do I need to do anything special or is this just not possible?

  • Best Practices for serializing/persisting String Object Dictionary entities

    - by Mark Heath
    I'm noticing a trend towards using a dictionary of string to object (or sometimes string to string), instead of strongly typed objects. For example, the new Katana project makes heavy use of IDictionary<string,object>. This approach avoids the need to continually update your entity classes/DTOs and the database tables that persist them with new properties. It also avoids the need to create new derived entity types to support new types of entity, since the Dictionary is flexible enough to store any arbitrary properties. Here's a contrived example: class StorageDevice { public int Id { get; set; } public string Name { get; set; } } class NetworkShare : StorageDevice { public string Path { get; set; } public string LoginName { get; set; } public string Password { get; set; } } class CloudStorage : StorageDevice { public string ServerUri { get; set } public string ContainerName { get; set; } public int PortNumber { get; set; } public Guid ApiKey { get; set; } } versus: class StorageDevice { public IDictionary<string, object> Properties { get; set; } } Basically I'm on the lookout for any talks, books or articles on this approach, so I can pick up on any best practices / difficulties to avoid. Here's my main questions: Does this approach have a name? (only thing I've heard used so far is "self-describing objects") What are the best practices for persisting these dictionaries into a relational database? Especially the challenges of deserializing them successfully with strongly typed languages like C#. Does it change anything if some of the objects in the dictionary are themselves lists of strongly typed entities? Should a second dictionary be used if you want to temporarily store objects that are not to be persisted/serialized across a network, or should you use some kind of namespacing on the keys to indicate this?

  • Sharing wireless internet connection between 2 Ubuntu 10.04 systems using cross-over cable

    - by Gary
    I have a Lenovo T60 with Ubuntu 10.04 connected with a cross-over cable to a Dell Vostro 1400, also running Ubuntu 10.04. My internet is coming into the Lenovo through an external wireless antennae, and I want to share the internet with the Dell. On the Lenovo: eth0 connection has IPv4 Settings 'Shared to other computers' I can ping the Dell (10.42.43.10) successfully I can use mtr to trace to www.google.com successfully On the Dell: eth0 connection has IPv4 Settings 'Automatic DHCP' I can ping the Lenovo (10.42.43.1) successfully when I use mtr to trace to www.google.com, I can only reach 10.42.43.1 I must be missing some setting, but cannot see what it is; can anyone help me?

  • Directories shown as files, when sharing a mounted cifs drive

    - by Johan Sigfred Abildskov
    I have an issue where a directory is shown as a file when accessing a samba share ( on Ubuntu 12.10 ) from a Windows machine. The output from ls -ll in the folder on the linuxbox is as follows: chubby@chubby:/media/blackhole/_Arkiv$ ls -ll total 0 drwxrwxrwx 0 jv users 0 Jun 18 2012 _20 drwxrwxrwx 0 jv users 0 Apr 17 2012 _2006 drwxrwxrwx 0 jv users 0 Apr 17 2012 _2007 drwxrwxrwx 0 jv users 0 May 12 2011 _2008 drwxrwxrwx 0 jv users 0 Feb 19 09:53 _2009 drwxrwxrwx 0 jv users 0 Dec 20 2011 _2010 drwxrwxrwx 0 jv users 0 May 8 2012 _2011 drwxrwxrwx 0 jv users 0 Mar 5 11:37 _2012 drwxrwxrwx 0 jv users 0 Feb 28 10:09 _2013 drwxrwxrwx 0 jv users 0 Feb 28 11:18 _Mailarkiv drwxrwxrwx 0 jv users 0 Jan 3 2011 _Praktikanter The entry in /etc/fstab is: # Mounting blackhole //192.168.0.50/kunder/ /media/blackhole cifs uid=jv,gid=users,credentials=/home/chubby/.smbcredentials,iocharset=utf8,file_mode=0777,dir_mode=0777 0 0 When I access the share directly from the NAS on my Windows box, there are no issues. The version of Samba is 3.6.6, but I couldn't find anything in the changelogs that seem relevant. I've tried mounting it in different locations with different permissions, users and groups but I have not made any progress Due to my low reputation on serverfault ( mostly stackoverflow user ) I'm unable to post a screenshot that shows that the directories are shown as files. If I type the full path in explorer, the directory listing works excellently, except for any subdirectories that are then shown as files. Any attack vector for this issue would be greatly appreciated. Please let me know if I have provided insufficient details. Edit: The same share when accessed from a OS X, works perfectly listing the directories as directories. Best Regards!

  • Sharing public key with ssh

    - by jtnire
    Hi Everyone, Is it possible to somehow setup an ssh server that doesn't require a username,password or cert to login? If that's not possible, if I were to give all customers the same public key, would each connection be encrypted individually? (i.e. user A coudn't decrypt the payload of user B's connection) I wish to provide access to a single program, which will prompt for a username and password. Encryption is essential though, and users must not be able to snoop in on each other Thanks

  • Server speed: sharing one script.php or using many copies the same script.php

    - by Marco Demaio
    Let's assume: I have thousands of domains on same Apache server. Each domain is in a folder under server public_html document folder, so it can be accessed by calling "www.somedomain.com" or by calling "www.serverdomain.com/somedomain_folder" In each domain there is a website who needs a certain script.php (identical for each domain). From a coding point view, its obvious that it's better to use a unique script.php, so when i update it with new features/bug fixes etc, I need to update on server only one file and it will work for all domains. But from a server point of view? If i use a unique script all domains will access it at the same time, will the server run slower compared to the situation where each domain called its own script?

  • How get and set accessors work

    - by Chris Halcrow
    The standard method of implementing get and set accessors in C# and VB.NET is to use a public property to set and retrieve the value of a corresponding private variable. Am I right in saying that this has no effect of different instances of a variable? By this I mean, if there are different instantiations of an object, then those instances and their properties are completely independent right? So I think my understanding is correct that setting a private variable is just a construct to be able to implement the get and set pattern? Never been 100% sure about this.

  • Need solutions in sharing a 3Mb/768Kbps DSL line to 60+ users and faster bandwidth

    - by elistp
    Two parts. Part 1: We currently have 2 DSL Lines with 3Mb/768Kbps speeds load balanced for 60+ users. Accessing the Internet is borderline unusable. The simple solution would be to get a faster DSL Line but the highest DSL package is 6Mb/768Kbps, has quite the price jump, and doesn't do anything to help with upload speeds. I'm looking for free or extremely low cost solutions (web cache, traffic shaping, bandwidth controls, etc) to help with making Internet access more bearable until the next funding year. Can anyone give any advice? Part 2: We're looking into a 4.5Mb bonded T1 in the next funding year which is of course significantly more expensive than 2 DSL lines. Are bonded T1s our only hope for faster speeds? Are there any better alternatives?

  • Rotation, further I go from 0:0, the further the object positions around the origin while rotating

    - by Serguei Fedorov
    For some reason I am having the issue where the following code: global.spriteBatch.Draw(obj.sprite, obj.getPosition(), null, Color.White, obj.rotation, obj.center, 2f, SpriteEffects.None, 1); causes the object to rotate around the origin in such a way, as though there is an offset to the position relative to its location. The calculation for the center it correct and this happens even if I set the pivot to be the location of the object. The further I get from 0:0 the larger the radius or rotation. I am not sure what is going on here because given the following tutorial http://www.riemers.net/eng/Tutorials/XNA/Csharp/Series2D/Rotation.php I have done the code setup correctly. Any ideas? Any help is greatly appreciated!!!

  • Sharing accounts between multiple computers running Ubuntu Linux

    - by john
    My school has a computer lab full of machines running Red Hat Linux. They have it set up so that you can log into any computer in the lab, and it automatically loads your desktop, home directory, etc, which makes it so all computers in the lab look the same to you, regardless or which one you're using. I have two computer at home running Ubuntu Linux. Could I do this same thing with my computers at home? What's it called, and how do I find documentation on how to set it up? Thanks!

  • Windows XP/Firewall -- Can't open UDP port 9100 for JetDirect sharing

    - by Barton Chittenden
    I'm setting up my Dad's laptop (Vista) to print to an HP Deskjet printer attached to a Windows XP Desktop box. The XP box is running Windows firewall. Laptop sits on 192.168.1.66, Desktop 192.168.1.65. I set up logging in the firewall, and determined that it is dropping inbound packets on TCP port 9100, used by JetDirect, the printing protocol. I set up an exception on TCP port 9100, allowing access to the local subnet. There's also an entry under the 'allow applications' tab which was marked for the exact printer model. I selected this as well, then tried to print again... I see more dropped packets from 192.168.1.66 to 192.168.1.65 for TCP port 9100. What do I try next?

  • PHP on several servers with session-sharing

    - by Etu
    there's certanly other threads about this, but I have one more question. We are about to scale the website at work to have more than one server. And we need to share the sessions between the servers. We have been looking into different solutions, one in memcached and use Memcached as sessionhandler in PHP. That will probably work. And the idea would be to run memcached on every machine and let all webservers access all other servers memcached servers, and then we have shared sessions between the machines, yay. (we have no resources to setup with sticky-sessions yet, that's a later project. we need this running, and we need this running now. and we will loadbalance with DNS for a starter) But then... If I want to take one server down, say, for maintenance, or a server crashes, or whatever reason. I don't want the users to just loose their sessions and have to start from the beginning... That's why we need some kind of replication, which Memcached does not support. Then I found http://repcached.lab.klab.org/ -- which has multi-master replication of memcached, which is great, and is what I want. But does it work with 2 machines? Say 3, 5, 10? For future scaling. I also looked into redishttp://redis.io/ -- which also seems great, but is a bit more "shaky" with the php-session-handler support, and no multi-master-replication. The thing is that I like to use memcached, but I want to be able to power down one of two boxes without loosing half of the sessions. Any suggestions?

  • Linux and Windows machines sharing a network

    - by Saif Bechan
    I have different Windows and Linux machines that share an internal private network. From within this network I can SSH to every machine etc. This internal network works great. I have my main windows machine from where I control these machines either trough SSH or virtual desktop. Is there a way for me on my main machine to see all the machines that are connected to the network. I want to be able to see all the machines and maybe browse them, share files etc. I am very new to networking of this kind so any recommendations are welcome. Should I set up this network by workgroup? I do not think Linux supports that. Or should I set up the network with domain, I never did that before.

  • How to move an object along a circumference of another object?

    - by Lumis
    I am so out of math that it hurts, but for some of you this should be a piece of cake. I want to move an object around another along its ages or circumference on a simple circular path. At the moment my game algorithm knows how to move and position a sprite just at the edge of an obstacle and now it waits for the next point to move depending on various conditions. So the mathematical problem here is how to get (aX, aY) and (bX, bY) positions, when I know the Centre (cX, cY), the object position (oX, oY) and the distance required to move (d)

  • Is OOP becoming easier or harder?

    - by tunmise fasipe
    When the concepts of Object Oriented Programming were introduced to programmers years back it looks interesting and programming was cleaner. OOP was like this Stock stock = new Stock(); stock.addItem(item); stock.removeItem(item); That was easier to understand with self-descriptive name. But now OOP, with pattern like Data Transfer Objects (or Value Objects), Repository, Dependency Injection etc, has become more complex. To achieve the above you may have to create several classes (e.g. abstract, factory, DAO etc) and Implement several interfaces Note: I am not against best practices that makes Collaboration, Testing and Integration easier

  • Sharing files between multiple sites using only desktop software

    - by perlyking
    Our organisation has three sites; a head office, where the master copies of company files are stored, plus two branch offices using only workstations and a NAS or two. Currently we're talking about <10GB. At the main office, we have no admin access to the file server, as this is entirely controlled by the larger institution where we are located. For the same reason, we have no VPN remote access to this network. Instead, we simply have access to a network share using over a Novell LAN. Question: how can we share files between offices in way that minimises latency, i.e. that gives us a mirror of the main network share at each site? (There is little likelihood of concurrent editing, and we can live with the odd file conflict now and again). Up to now branch office staff have had to use GotoMyPC-type solutions to remotely access files held at the main office. Or email. I was hoping to use Google Drive on a dedicated workstation at each office to sync the contents of the network share (head office) or NAS (branch offices) via the cloud, but at my last attempt (29 Jun '12), the Google Drive installer would not allow me to designate the remote network share as the "target" folder. (I chose Google Drive over Drobbox et al. as we already use GMail for corporate mail) The next idea was to use a designated workstation at head office to mirror the network share to a local drive, then use Google Drive to push that to the cloud. This seems a step too far. Nor do I have any good ideas about how to achieve this network/local mirroring, as we can't, for example, install the rsync daemon on the server. I do not want to use Google Drive locally on each workstation as this will inconvenience users, and more importantly, move files off the backed-up, well-maintained (UPS, RAID etc) network share at head office. Our budget is only in the £100's. Should we perhaps just ditch the head office server and use something like JungleDisk? At least this presents the user with what appears to be a mapped drive.

  • Getting started with object detection - Image segmentation algorithm

    - by Dev Kanchen
    Just getting started on a hobby object-detection project. My aim is to understand the underlying algorithms and to this end the overall accuracy of the results is (currently) more important than actual run-time. I'm starting with trying to find a good image segmentation algorithm that provide a good jump-off point for the object detection phase. The target images would be "real-world" scenes. I found two techniques which mirrored my thoughts on how to go about this: Graph-based Image Segmentation: http://www.cs.cornell.edu/~dph/papers/seg-ijcv.pdf Contour and Texture Analysis for Image Segmentation: http://www.eng.utah.edu/~bresee/compvision/files/MalikBLS.pdf The first one was really intuitive to understand and seems simple enough to implement, while the second was closer to my initial thoughts on how to go about this (combine color/intensity and texture information to find regions). But it's an order of magnitude more complex (at least for me). My question is - are there any other algorithms I should be looking at that provide the kind of results that these two, specific papers have arrived at. Are there updated versions of these techniques already floating around. Like I mentioned earlier, the goal is relative accuracy of image segmentation (with an eventual aim to achieve a degree of accuracy of object detection) over runtime, with the algorithm being able to segment an image into "naturally" or perceptually important components, as these two algorithms do (each to varying extents). Thanks! P.S.1: I found these two papers after a couple of days of refining my search terms and learning new ones relevant to the exact kind of techniques I was looking for. :) I have just about reached the end of my personal Google creativity, which is why I am finally here! Thanks for the help. P.S.2: I couldn't find good tags for this question. If some relevant ones exist, @mods please add them. P.S.3: I do not know if this is a better fit for cstheory.stackexchange (or even cs.stackexchange). I looked but cstheory seems more appropriate for intricate algorithmic discussions than a broad question like this. Also, I couldn't find any relevant tags there either! But please do move if appropriate.

  • Resource Pool sharing in Hyper-V Virtual Machines

    - by user67905
    I understand that we can install Hyper-V on one server and run a number of Virtual Machines on it, upto the limit of resources of that server. I want to know if it is possible to install Hyper-V lumped on two or more servers, so that the Virtual Machines can use the underlying resources pool of both the servers? And also if that same is possible for an “n” number of servers, instead of just 2 servers.

  • How to allow simple file sharing on Windows Server 2008R2 through VPN

    - by Martin Wiboe
    We are a small, distributed company with a Windows Server 2008R2 installation. I would like to set up a way for our employees to connect securely to this server via VPN and then be able to map a network drive. I have gotten this to work somewhat by installing the Network Policy and Access Services Role on the server and using the default settings. I have also created a network share on the server. The problem is that our connectivity is sporadic (sometimes the service stops listening on the port or simply refuses to authorize correct credentials) and slow. I can always connect through VPN, but mapping is problematic. I would be grateful for the answer on how to accomplish this as well as some guidance on whether I am on the right track. Thanks in advance!
