• Designing extensible, interactive systems

  - by vemv

  Steve Yegge's The Pinoccio Problem describes a very special type of program: one that not only fulfills the original purpose of its creators, but also is capable of performing arbitrary, user-defined computations. They typically also host a console, by which one can reprogram the software on runtime, maybe persisting the modifications. I find this problem very hard to reason about - there seems to be a conflict between implementing the 'core modules' of a program, and making the system really implementation-agnostic (i.e. no functionality is hard-coded). So, how to architecture such a program - what techniques can help? Is it a well-studied topic?

• What library should I use for 2D Geometry? [closed]

  - by Luka

  I've been working on a 2D game in java, but found that java just didn't cut it for me and had forced me to a lot of bad design choices, so I've decided to port all my work to c++. The main reason I've decided change to c++ is that i had reached a point where i had 3 geometry libraries (the native, one from the game engine and one to handle "complex" polygons), none of witch worked very well together and i couldn't keep track of them. I'm new to c++, but i know all the basics. My question is, what would be a good geometry library to use, ideally it should be able to handle integer and decimal data types, have point, line, and polygon classes witch are able to check for intersection and contains. Thanks in advance, Luka

• How is Basic Physics applied in CS/SE?

  - by Wulf

  What basic physics principles do software engineers and/or computer scientists use to help solve specific or common problems? The first one that came to my head was creating a Physics engine for a game; physics is involved, as it requires knowledge of: Forces and Motion: Kinematics, Dynamics, Circular Motion However, I need another example, but haven't come across one that involves basic physics. Please consider the following basic physics (grade 12 level) concepts: Energy and Momentum: Work and Energy, Momentum and Collisions, Gravitational and Celestial Mechanics Electric, Gravitational & Magnetic Field: Electric Charges and Electric Field, Magnetic Fields and Electomagnetism The Wave Nature of Light: Waves and Light, Wave Effects of Light Matter-Energy Interface: Einstein’s Special Theory of Relativity, Waves, Photons and Matter, Radioactivity and Elementary Particles I will be happy with any response; Keywords for google, names of methods like raycasting, etc.

• Hosting a website from a dynamic IP

  - by nick

  I recently upgraded my internet to the point that it is much faster and more reliable than my current webhost. I would like to move my current domain to be hosted at home, but my IP address is dynamic. As far as I know, I only get a new IP when I restart my modem and or router (which is almost never) or when cable one (my ISP) pushes out a firmware update (rarely). There are a few ways I can see doing this 1) convince my ISP to give me a static IP 2) assign my router my current IP to force a static IP (which might work?) 3) set my dns record to my current IP address and update it on the rare occasions that it changes. Obviously I'm hoping that the first one works, but I don't want to pay a lot of extra money (if that's what it takes) to get a static IP address. Has anyone had any luck with something like that?

• Advanced Charts Part I

  - by Tim Dexter

  Yeeeep! Another series looms ... this one could stretch out a bit and more options become available. Ever needed to generate something similar to these? Beyond what BIP can provide today but there are a few options; one from Oracle and R, now out in the wild and another out there from JFreeChart, open source and therefore almost free. Of course Google is ever present and they have been extending their chart support. I blogged the How for Google charts a while back here. Different ways to integrate but they can all help to close the charting gap for you.

• What are the technial and programming requirements for writing a stealth keylogger?

  - by user970533

  I'm planning to write/code one such stealth keylogger that would bypass detection by a certain antivirus. (I don't want to name the vendor as I know how good Google queries are against StackExchange websites). I don't want to just download any keylogger from internet and try to encode it to evade detection. Writing code myself I would have the ability to make changes as I go; obscuration on both high-level and low-level language. I like control too. It seems naive but is it true that keyloggers are a thing of the past, probably because of how effective AV's have become in detecting such programs? I want some nice points on how can one easily write a robust, effective key logger preferably for a Windows environment?

• How to add a command permanently to grub2

  - by tomodachi

  I have a fairly special setup, using Linux on a MacBook Laptop. to switch off my secondary graphics card in it I'm required to add these lines to my grub outb 0x728 1 outb 0x710 2 outb 0x740 2 outb 0x750 0 I do this by pressing 'e' for my selected grub menu option and adding the lines one by one . then finally booting . But as we know it's not permanent. I cant really figure out where i need to add it for grub to always append it to my Linux boot options. It's doesn't seem to belong in /etc/default/grub since here i can add stuff to the kernel boot line Honestly i'm afraid to fiddle to much with grub on my computer since getting it to triple boot Linux/Mac/Windows was a very delicate and timely matter. Does anyone have any idea of where to add it?

• Non persistent keyboard shortcuts in Unity

  - by nblumoe

  I did change the keyboard shortcuts for window navigation in Unity to use hjkl (vim movement). I did reassign the shortcuts via GUI in System Settings Keyboard Shortcuts. Here are two examples of the assigned shortcuts: Move window one workspace to the left = Shift+Ctrl+Alt+H Switch to workspace left = Ctrl+Alt+H Occasionally, when restarting the maching, these shortcuts are being reset to theit default values: Move window one workspace to the left = Shift+Ctrl+Alt+Left Switch to workspace left = Ctrl+Alt+Left How can I make these changes permanent? Can someone help me, narrowing down the problem?

• booth multiplication algorithm

  - by grassPro

  Is booth algorithm for multiplication only for multiplying 2 negative numbers (-3 * -4) or one positive and one negative number (-3 * 4) ? Whenever i multiply 2 positive numbers using booth algorithm i get a wrong result. example : 5 * 4 A = 101 000 0 // binary of 5 is 101 S = 011 000 0 // 2's complement of 5 is 011 P = 000 100 0 // binary of 4 is 100 x = 3 y = 3 m = 5 -m = 2's complement of m r = 4 After right shift of P by 1 bit 0 000 100 After right shift of P by 1 bit 0 000 010 P+S = 011 001 0 After right shift by 1 bit 0 011 001 Discarding the LSB 001100 But that comes out to be the binary of 12 . It should have been 20(010100)

• EAV - is it really bad in all scenarios?

  - by Giedrius

  I'm thinking to use EAV for some of the stuff in one of the projects, but all questions about it in stackoverflow end up to answers calling EAV an anti pattern. But I'm wondering, if is it that wrong in all cases? Let's say shop product entity, it has common features, like name, description, image, price, etc., that take part in logic many places and has (semi)unique features, like watch and beach ball would be described by completely different aspects. So I think EAV would fit for storing those (semi)unique features? All this is assuming, that for showing product list, it is enough info in product table (that means no EAV is involved) and just when showing one product/comparing up to 5 products/etc. data saved using EAV is used. I've seen such approach in Magento commerce and it is quite popular, so may be there are cases, when EAV is reasonable?

• What caused you to stop using UML tools on your team?

  - by jamie

  There seems to be plenty of good, free UML tools. I hear about UML tools being used by large organizations, and they seem to have plenty of advocates. However, in my career I have never seen them used beyond "dabbling". Now, I have seen many UML diagrams drawn on whiteboards, and I use them myself all the time, on paper, to think about problems. I've also seen articles such as this one claiming why developers don't use UML, but the arguments just don't land with me. Frankly, this seems like an opportunity for a start-up if one can figure out why developers really don't use them, and solve those problems. So I'm asking anyone here who has attempted to use UML tools in a team, and stopped, this question: "why did you stop?" I'm especially interested in experience from agile teams. I am looking for concrete experience, not hypothetical opinion. Thanks.

• If most of team can't follow the architecture, what do you do?

  - by Chris

  Hi all, I'm working on a greenfields project with two other developers. We're all contractors, and myself and one other just started working on the project while the orginal one has been doing most of the basic framework coding. In the past month, my fellow programmer and I have been just frustrated by the design descisions done by our co-worker. Here's a little background information: The application at face value appeared to be your standard n-layered web application using C# on the 3.5 framework. We have a data layer, business layer and a web interface. But as we got deeper into the project we found some very interesting things that have caused us some troubles. There is a custom data access sqlHelper type base which only accepts dictionary key/valued entries and returns only data tables. There are no entity objects, but there are some massive objects which do everything and then are tossed into session for persitance. The general idea is that the pages (.aspx) don't do anything, while the controls (.ascx) do everything. The general flow is that a client clicks on a button, which goes to a user control base which passes a process request to the 'BLL' class which goes to the page processor, which then goes to a getControlProcessor, which at last actually processes the request. The request itself is made up of a dictionary which is passing a string valued method name, stored procedure name, a control name and possibly a value. All switching of the processing is done by comparing the string values of the control names and method names. Pages are linked together via a common header control that uses a combination of javascript and tables to create a hyperlink effect. And as I found out yesterday, a simple hyperlink between one page and another does not work because of the need to have quite a bit of information in session to determine which control to display on a page. My fellow programmer and I both believe that this is a strange and uncommon approach to web application development. Both of us have been in this business for over five years and neither of us have seen this approach. My question is this, how would we approach our co-worker and voice our concerns and what should we do if he does not want to accept the criteic? We both do not want to insult the work that has been done, but feel that going forward will create a nightmare for development. Thanks for your comments.

• Linqpad and Autocompletion

  I have mentioned before about doing development for StreamInsight in Linqpad. I have it installed on two separate PCs and I have enabled autocompletion on only one of them. Whilst both versions are an excellent tool, the one with autocompletion enabled is so much easier to use. After enabling autocompletion you can see I now get parameter listing Free trial of SQL Backup™“SQL Backup was able to cut down my backup time significantly AND achieved a 90% compression at the same time!” Joe Cheng.

• .htaccess 301 Redirect for wildcard subdomains

  - by Steve

  I run Wordpress in Network mode, which means I can have multiple websites running off one installation of Wordpress. Each website runs as a subdomain. Wordpress handles this using .htaccess, and a wildcard subdomain pointing to the location of Wordpress, so there are no actual subdomains created in cPanel; just a wildcard subdomain in cPanel, ad Wordpress handles the rest. I want to 301 redirect http://one.example.com/portfolio to http://two.example.com/portfolio. If I only have 1 .htaccess file in the web root of example.com, how do I achieve this?

• Network programming under windows: is WSA functions can be more complete than pSock functions [on hold]

  - by Kane

  I plan to make a set of classic socket functions to simplify their usages. Since i work under windows and linux indifferently i usually make it portable (it's not my first version of this set of functions), but i want to do something different this time and dedicate one version to windows, and one other to linux. With that i wonder for the windows version, if the WSA* functions can have any interest using them instead of the psock ones. I have found nothing about a comparison between them, so if any of you have any idea, suggestion, link or benchmark ?

• Most supported/easiest to get started gamedev language?

  - by user1009013

  In what language are the most libraries/frameworks (like lwjgl for Java, XNA for C#)? What language is the easiest to start making a game (very easy to get a 3D-environment rendered)? What language has the friendliest learning curve? Say I want to make a game and I don't know any programming languages, I want to develop for any platform(so don't give the answer "the one you know best/the platform you are working on"), then what is the best language to start with. I get this question a lot "I have this and that ideas for a game and want to make it, what language should I use"(mostly asked by beginning programmers), but I don't know how to answer that. The answer "use the one you are most familiar with", because sometimes they don't even know a language yet... I am not asking for someone's personal opinion, but an objective list of what languages are the easiest/most supported/have the most/best libraries/frameworks to get started with gamedevelopment.

• Code Design question, circular reference across classes?

  - by dsollen

  I have no code here, as this is more of a design question (I assume this is still the best place to ask it). I have a very simple server in java which stores a mapping between certain values and UUID which are to be used by many systems across multiple platforms. It accepts a connection from a client and creates a clientSocket which stores the socket and all the other relevant data unique to that connection. Each clientSocket will run in their own thread and will block on the socket waiting for a read. I expect very little strain on this system, it will rarely get called, but when it does get a call it will need to respond quickly and due to the risk of it having a peak time with multiple calls coming in at once threaded is still better. Each thread has a reference to a Mapper class which stores the mapping of UUID which it's reporting to others (with proper synchronization of course). This all works until I have to add a new UUID to the list. When this happens I want to report to all clients that care about that particular UUID that a new one was added. I can't multicast (limitation of the system I'm running on) so I'm having each socket send the message to the client through the established socket. However, since each thread only knows about the socket it's waiting on I didn't have a clear method of looking up every thread/socket that cares about the data to inform them of the new UUID. Polling is out mostly because it seems a little too convoluted to try to maintain a list of newly added UUID. My solution as of now is to have the 'parent' class which creates the mapper class and spawns all the threads pass itself as an argument to the mapper. Then when the mapper creates a new UUID it can make a call to the parent class telling it to send out updates to all the other sockets that care about the change. I'm concerned that this may be a bad design due to the use of a circular reference; parent has a reference to mapper (to pass it to new ClientSocket threads) and mapper points to parent. It doesn't really feel like a bad design to me but I wanted to check since circular references are suppose to be bad. Note: I realize this means that the thread associated with whatever socket originally received the request that spawned the creation of a UUID is going to pay the 'cost' of outputting to all the other clients that care about the new UUID. I don't care about this; as I said I suspect the client to receive only intermittent messages. It's unlikely for one socket to receive multiple messages at one time, and there won't be that many sockets so it shouldn't take too long to send messages to each of them. Perhaps later I'll fix the fact that I'm saddling higher work load on whatever unfortunate thread gets the first request; but for now I think it's fine.

• movement of sprites with kinect and xna

  - by pablopp83

  im working on a proyect with kinect sdk and xna 4.0. i need take the position of the hands and draw a sprite over it. im doing it directly and, because of that, i get a "trembling hands" effect. so, i was thinking on make the sprite move from the previous position to the new one, given in every frame by the new hand position. this way, the sprite does not jump from one position to another. this is working just fine, but im using a constant value for the velocity, and i really would like to use a variable velocity given by the difference between the prev and the new position. this is, if the hand move more quickly in the reality, the velocity will be higher. I really dont have a clue on how to make this works. can somebody point me in the right direction? thanks.

• How to remove shells?

  - by MyNameIs...

  I installed few shells that I wanted to try out on Ubuntu 12.04, but none of them worked at all. It could be that I installed them all at the same time, meaning the OS didn't get a chance to work everything out, but either way, they didn't work. I would now like to remove them. The one's that I installed are Fluxbox, OpenBox, XFCE, and MATE. I installed them through the help of this site. Everything seemed to have been working properly until I actually tried to use the shells and nothing loaded at all. Except for Fluxbox, I think that one worked. I want to know of any way to repair or perhaps just remove the packages entirely. I might have already removed them because I did the apt-get remove command on all of them, but they were still in the list on the login screen.

• Managing multiple people working on a project with GIT

  - by badZoke

  I'm very new to GIT/GitHub (as new as starting yesterday). I would like to know what is the best way to manage multiple people working on the same project with Github. Currently I'm managing one project with four developers. How do I go about the workflow and making sure everything is in sync? (Note: All developers will have one universal account.) Does each developer need to be on a different branch? Will I be able to handle 2 people working on the same file? Please post a detailed answer, I'm not a shy reader. I need to understand this well.
