• Which other "photo booth" program can I use besides cheese (on a Toshiba AC100)?

  - by imz

  After installing Ubuntu 12.04 on a Toshiba AC100 several days ago, as described at https://wiki.ubuntu.com/ARM/TEGRA/AC100, and seeing during the installation that the OS was able to use the camera (the installer suggested to make a photo for the first user), I wanted to play with the camera. I couldn't understand how to find a "photo booth" program in the new-style menu+desktop (not the classical menu with sections), so I remembered the popular "cheese" Linux program, and installed it via the Software Update tool (or whatever it is called; can be invoked from the panel on the desktop). But cheese doesn't start, i.e., it crashes. (The bug report telling the same.) As I said, the camera could be used by the OS on this machine -- this could be seen in the installer. Which "photo booth" programs can be installed and used without crashes in Ubuntu 12.04 on a Toshiba AC100 in order to play with the webcamera?

• What time to display in text messages in multiplayer game?

  - by Krom Stern

  Say I'm having a multiplayer RTS game. There's a main server for each individual game and several clients connected to it. All packets are sent to server first and then server retransmits them back to clients. Say Server is located in one time-zone and all of the clients are in different time-zones. ClientA send a text message in chat at 12:03, what times should be stamped for other clients? Should his message be uniformely timestamped by Server (12:02) or each client should timestamp the message whenever it is recieved (12:04, 16:04, 03:03, etc..). Bear in mind, that all the messages are to be in the same order on all clients, server takes care of that. So thats the question - use local time for each client or use global server time to timestamp chat messages?

• Background & Research Methods section (Writing an Article)

  - by sterz

  It is my first time writing an article on a software project. I am supposed to use ACM UbiComp paper format. I already have a structure that I should follow and there is a Background & Research Methods section after Abstract, Introduction, Related Work sections. I have browser through several articles, but some of them either dont have it, have only background section or have only research methods section. I am having hard time to find an article that has this section and moreover what I must write on here. My project is about Bluetooth location tracking and I do have the implementation and evaluation, so it is not something theoretical.

• Problems installing Ubuntu on unallocated space

  - by Adam

  I've been trying to install Ubuntu on some unallocated space, but I'm getting confused with the manual partition setup. I didn't want to try the other options for it suggested that everything on my drive would be erased (but I might be wrong) I have an old(ish) laptop with a 60GB hard-drive. Theres a Windows 7 partition of 30GB, followed by 20GB of unallocated space, then HP's Windows recovery partition of under 10GB. Do I need to format the empty space in windows first? What's the recommended method in this case?

• Ubuntu 13.10 Security Key

  - by Toby J

  I was attempting to install Ubuntu 13.10 today and it came up with a screen asking for me to setup a security key. In the first place, I'm not sure what a security key is, but It said I would have to enter it everytime I booted Ubuntu so I assume it's the same thing as a logon password in Windows 8. Is there anyway I can bypass this step without setting up a security key or logon password? I hate these things and have always avoided them in Windows. I don't need them as there is never anyone but myself and my wife on our computers. We are retired, no children or nieces, nephews, friends, etc. who ever use our computer and we don't have any security information such as SS #, etc. on it. Also, I quit the installation at this point but I was not seeing any of the screen prompts as listed in the setup instructions on the Ubuntu website. Has the setup for Ubuntu 13.10 changed since these instructions were written? Thanks

• AMD Catalyst diskless cluster

  - by Nathan Moos

  I'm using Ubuntu 13.10 to set up a diskless compute cluster. When I use the procedure detailed in https://help.ubuntu.com/community/DisklessUbuntuHowto, I successfully am able to boot all four nodes. However, once I install Catalyst, I immediately have problems: only one diskless node boots properly, with the other two hanging while attempting to start X. My assumption is that my Catalyst build was somehow specific to the node which I booted from first, which somehow prevents the other nodes from loading Catalyst. Can anyone provide hints to help solve this? Thank you in advance!

• Create a fast algorithm for a "weighted" median

  - by Hameer Abbasi

  Suppose we have a set S with k elements of 2-dimensional vectors, (x, n). What would be the most efficient algorithm to calculate the median of the weighted set? By "weighted set", I mean that the number x has a weight n. Here is an example (inefficient due to sorting) algorithm, where Sx is the x-part, and Sn is the n-part. Assume that all co-ordinate pairs are already arranged in Sx, with the respective changes also being done in Sn, and the sum of n is sumN: sum <= 0; i<= 0 while(sum < sumN) sum <= sum + Sn(i) ++i if(sum > sumN/2) return Sx(i) else return (Sx(i)*Sn(i) + Sx(i+1)*Sn(i+1))/(Sn(i) + Sn(i+1)) EDIT: Would this hold in two or more dimensions, if we were to calculate the median first in one dimension, then in another, with n being the sum along that dimension in the second pass?

• How do I select DWM or fluxbox to start on login?

  - by axe

  I am trying to setup DWM in Ubuntu 10.10. The package is successfully built - and now I am trying to get it up and running. I created the dwm.desktop file with the proper text and the path to the dwm exec is correct. On login screen, I can see dwm as a alternate session : but if I select it, still gnome starts. I even tried another window manager (fluxbox) - same problem. I can see and select it in the login screen, but gnome starts up. Trying gconftool-2 -s /desktop/gnome/session/required_components/windowmanager dwm --type string also does nothing. Killing the windows manager just restarts it - even if I chvt first. Also, don't see the xinit daemon running. Any ideas ? This setup was trivial in Debian, and older versions of Ubuntu. What changed ? I am guessing gnome integration is to blame - but am clueless as of now.

• What top companies look for in an Interview?

  - by Geek

  Basically I am looking for what is it that you goof up and you are out from the remaining process ? Are elimination rounds a fair way to judge a person ? Anyone can have a bad hour :-( Should you code the best possible or should you get the Algorithm right ? I generally first code a workable solution and then work on it till a level I think it looks beautiful to me. Is this a wrong approach ? Recently I had a telephonic interview in which I was asked to write a variation of Level Order traversal in 20 minutes. I could get the Algorithm and working code in 20 minutes but couldn't get the Exception handling and the coding convention right, after which I didn't hear back from them :-( All the other questions in the interview went very well this was the only thing which was 'not upto the mark'. Needless to say I like the company and will apply again but want to get it right the next time :-) Please share your experiences and valuable suggestions.

• XHTML fix solution republished

  - by TATWORTH

  As a post VS2010 SP1 installation activity, I am recompiling all my open source projects. The first is XHTMLFIX at http://xhtmlfix.codeplex.com/ This LGPL project has simple fixes to ASP.NET 2.0/4.0 to achieve XHTML compliance as measured by the W3C tests at http://validator.w3.org/ The XHTML project shows as untrue the commonly held belief that MVP or MVC are necessary for producing XHTML compliant web pages. Incidentally the other supposed advantage of MVP and MVC over web forms of easier testing is also very dubious as web forms can be tested by systems such as Selenium or WaTiN. I have used NUnitASP (alas sadly discontinued) with web forms and found it be more effective than unit testing MVP. Now if you prefer the MVP and / or MVC approach over Web forms then fine, that is your preferance. Now if you can find an example where ASP.NET 4.0 Web forms properly written do not produce XHTML compliant markup, I would be glad of your example and will look at ways of modifying the markup to be XHTML compliant.

• About lenguages strongly typed with late binding, do they make sense?

  - by llazzaro

  I never learnt anything about VB6 (and I dont want to) but I wanted to search for bad things in computer software, so my first though was VB6. So for example, VB6 was strongly typed with late binding. Makes some sense to have a language with that combination? (I dont think so). I want to know reasons of why VB6 was like this! or why is good idea for a lenguage to be like this. Bad things that happend with a lengugage like this? good things?

• Ubuntu 10.10 crashing on initialization, how to solve?

  - by Tom Brito

  Yesterday I installed Ubuntu 10.10, and on the first login it got frozen, so I powered off and on the computer, and it started well. Now, during the updates it got frozen again, and after every login again. I can't even change to the command line with ctrl+f1 or f2. Is there a way to get some log information on the initialization? I have no idea what can be causing this. Previously I was using Ubuntu 9.04, which is now not receiving new updates. Versions 10.04 and 9.10 behavior the same as 10.10, and version 11.04 crashes much on many situations. So, is there a way to get some log information on the initialization to help find what's wrong?

• .htaccess file to implement multiple redirects

  - by RobMorta

  I have a dynamic site and from .htaccess file creating clean URLs: RewriteCond %{REQUEST_URI} !(\.png|\.jpg|\.gif|\.jpeg|\.bmp)$ RewriteRule ^([a-zA-Z0-9_\-\+\ ]+)$ flight.php?flights=$1&slug=$1 This code worked fine for me but when I created a new type of page and trying to get clean URLs with the same code i.e.: RewriteCond %{REQUEST_URI} !(\.png|\.jpg|\.gif|\.jpeg|\.bmp)$ RewriteRule ^([a-zA-Z0-9_\-\+\ ]+)$ manual-page.php?url=$1&slug=$1 it's not working and if I comment the previous two lines then its is working fine. Only one code is working at a time. For first I have a URL domain.com/flight.php?flight-san-fransisco-london-flights and I want this being redirect to domain.com/san-fransisco-london-flights & from the second one I have domain.com/manual-page.php?url=my-new-page and I want this being redirect to domain.com/my-new-page. Is these any way to get both working together?

• Inexpensive generation of hierarchical unique IDs

  - by romaninsh

  My application is building a hierarchical structure like this: root = { 'id': 'root', 'children': [ { 'name': 'root_foo', 'children': [] }, { 'id': 'root_foo2', 'children': [ { 'id': 'root_foo2_bar', 'children': [] } ] } ] } in other words, it's a tree of nodes, where each node might have child elements and unique identifier I call "id". When a new child is added, I need to generate a unique identifier for it, however I have two problems: identifiers are getting too long adding many children takes slower, as I need to find first available id My requirement is: naming of a child X must be determined only from the state in their ancestors When I re-generate tree with same contents, the IDs must be same or in other words, when we have nodes A and B, creating child in A, must not affect the name given to children of B. I know that one way to optimize would be to introduce counter in each node and append it to the names which will solve my performance issue, but will not address the issue with the "long identifiers". Could you suggest me the algorithm for quickly coming up with new IDs?

• As a Junior Software Engineer should I say that something has been done wrong if I feel so?

  - by Why123

  I recently joined a company and it is my first job. When reading the code base, I felt that the code was not well written. It seemed to me that the code had most of the problems mentioned here and also seemed to have an Anemic Domain Model. There are no unit tests and they don't employ any code quality checking tools like findbugs or pmd. The problem I have is that the code is very difficult to understand. Maybe my conclusions are wrong because I am not that experienced. I need advice on whether to communicate the above facts to a superior or not. If I am to communicate, to whom(Tech Lead, Architect, Product Manager) and how? And if I do communicate will they take it badly since I'm a Junior and has no experience?

• How much C/C++ knowledge is needed for Objective-C/iPhone development?

  - by BFree

  First, a little background. I'm a .Net developer (C#) and have over 5 years experience in both web development and desktop applications. I've been wanting to look into iPhone development for some time now, but for one reason or another always got side tracked. I finally have a potential project on the horizon, and I'm now going full steam ahead learning this stuff. My question is this: I haven't done any C/C++ programming since my schooling days, I've been living in managed land ever since. How much knowledge if any is needed to be successful as an iOS developer? Obviously memory management is something that I'll have to be conscious about (although with iOS 5 there seems to be something called ARC which should make my life easier), but what else? I'm not just talking about the C API (for example, in order to get the sin of a number, I call the sin() function), that's what Google is for. I'm talking about fundamental C/C++ idioms that the average C# developer is unaware of.

• Ubuntu 11.04 Compiz crash after using Macbuntu script

  - by iman

  First of all, I have to say I am new to using Linux! I have installed Ubuntu 11.04 and I wanted to change its interface by using Macbuntu 10.10. I've done it but the problem is that genie effect was not activated until now. So I searched in many forums and I found out that I must change my compizconfig manager! I've done it but when I try to use this command: compiz --replace my laptop crashes, so I could not move any windows or terminal! I could not minimize or close them! What I am supposed to do for solving this crash???

• Is self learning Computer Science/programming over a college degree worth it? [on hold]

  - by user106576

  I am currently in college and I just want to skip to learning and gaining experience in what I came here to do, but unfortunately the first two years of college is general classes that everyone takes. I have a couple of friends that are also in Computer Science and we were planning on starting a small company/self employment. Would dropping out and gaining experience and a portfolio qualify for smaller companies if I look for a job there? What programs should I learn, and which ones should I learn before others to better understand the programs that are harder?

• How to solve problems with movement in simple tile based multiplayer game?

  - by Murlo

  I'm making a simple tile based 2D multiplayer game in JavaScript using socket.io where you can move one tile every 200 ms. The two solutions I've tried are as follows: The client sends "walk one tile north" every 200 ms. Problem: People can easily hack the client to send the action more often. The client sends "walking north" and "stopped walking". Problem: Sometimes the player moves extra steps when "stopped walking" doesn't arrive in time. Do you know a way around these problems or is there a better way to do it? EDIT: Regarding the first solution I've tried adding validation on the server to check if it has been 200 ms since last movement. The problem is that latency still encourages people just to spam the action as much as possible, giving them an unfair advantage.

• XNA - Debugging/Testing Individual Sprites and Pixel Collision

  - by kwelch

  I ran through the first training on XNA where you make a shooter game. They did some thing that I would not do and I want to use their starting point to learn more things. I want to try better collision and adding a menu. I saw something online with the sonic physics where they have a frame by frame of sonic moving 1 pixel. See picture below. I am new to development, but I have been programming for years now. What would you guys suggest to try these different things out. How would I simulate a similar frame by frame testing as they do in the above picture? Thanks!
