  • How do I secure a Tomcat installation?

    - by spangeman
    I have installed tomcat on my Ubuntu Home 11.10 system and can successfully access the test page online after port forwarding on 8080 within my router. I have not made any other changes to the router, Ubuntu or the tomcat install, everything else has remained standard. I intend on using this to play around with Java Servlets and basic web development for my own personal use. What steps, if any, would you suggest I take to ensure this is secure? Should I change anything within the Tomcat configuration? This seemed like a good idea to limit access - http://www.seankilleen.com/2010/09/how-to-allow-only-specific-ip-addresses_30.html But I am open to any other recommendations.

  • Looking to create a website ... need assistance on what technologies to use!

    - by rsala004
    First off, My group and I don't have any experience with databases or anything of that sort, only programming (not web-programming), so this post is just me wondering what things I should start researching and possibly some referral to a hosting company. The abstract idea is to have a list of things, each categorized, and each item with user-submitted reviews (made by users who are signed up with the website). Would absolutely everything be stored on a SQL database? (the long text reviews for example) Does anyone have any suggestions on some 'web frameworks' we could use to jumpstart us? What should our absolute first step be? (I was thinking about first designing the basic database? so we have something to work around...?) Should we worry about which host we choose right now, any recommendations? (would it be a trivial task to switch hosts in the future?) Thanks again, any help is appreciated!

  • More complex learning source for C# .NET [closed]

    - by Leron
    By complex I don't mean more difficult but including a larger area of possibilities cover. I've started a few years ago with PHP and the transition from learning the syntax of the language and the basic logical structures to working with databases, including JavaScript and so on was very short. And now I'm more interested in studying working with languages like Java/C#. Recently I spend a lot of time reading and writing some simple console applications, I've read almost 2K pages for C# programming and still don't know how to connect to database for example. Just for info I'm interested in web development, socket programing and live streaming, don't know if I'm exceeding myself too much writing that but despite that I want to find some books/internet sources where I can extend my current knowledge of C#/.NET, start using database queries, maybe try something more complicated webwise.

  • How can you put all images from a game to 1 file?

    - by ThePlan
    I've just finished a basic RPG game written in C++ SFML, I've put a lot of effort into the game and I'd want to distribute it, however I've ran into a small issue. Problem is, I have well over 200 images and map files (they're .txt files which hold map codes) all in the same folder as the executable, when I look in the folder, it makes me want to cry a little bit seeing so many resources, I've never seen a game which shows you all the resources directly, instead I believe they pack the resources in a certain file. Well, that's what I'm trying to achieve: I'm hoping to pack all the images in 1 file (Maybe the .txt files as well) then being able to read from that file or easily add to it.

  • Can't find my DVD drive in Ubuntu 12.04

    - by user72953
    I am completely new to Linux, due to some problems in my Windows I decided to give Linux a try. I am quite liking it accept for some minor issues. The biggest of them is that I cannot find my DVD drive in Ubuntu. After I insert the disk, the drive's green light flickers and then nothing. I don't get anything on my unity bar or desktop. There is no folder inside my /dev folder which indicates a dvd drive. There is a cdrom folder in my root folder but nothing is there. If you guys know what's wrong, I'd appreciate the help. Am a complete newbie so don't expect me to know anything about Ubuntu, although I have spent lots of hours in last 2 days googling my issue so I have basic information...

  • << and >> in C++

    - by JacKeown
    I don't quite understand what this means...I'm just learning C++ from my very very very basic Python experience...and so this may be a very stupid question. My question is...say you have your classic "Hello World" program and you have the line: cout<<"Hello World!"<<endl; what does the << mean...because I was just looking at using input in C and saw that you'd do something like: int i; cini; and I noticed that it has instead of << and I've read that those are bitwise shifts...and I don't exactly understand what those are...but I think it might be different here...Help...Thanks in advance

  • Developing a search algorithm

    - by Richart Bremer
    I want to create a basic search engine, and I want you to give me some ideas how to filter out the best results for my visitors. I have three fields regarding a product the user can search in: Title Category Description I came up with these ideas and I ask you to either competently criticize them or add to them. If the search term occurs in all three fields it should be among the first results. If it is in two of the fields it is below the results of 1. Combine the amount of occurences and output a value in per cent. For instance if in all fields together the term clock appeared 50 times and in all fields together there are 200 words, then the per cent value is 50/200*100 = 25%. Another product entry amounts to say 20% so product one having 25% is listed before product two having 20%.

  • What kind of math should I be expecting in advanced programming?

    - by I_Question_Things_Deeply
    And I don't mean just space shooters and such, because in non-3D environments it's obvious that not much beyond elementary math is needed to implement. Most of the programming in 2D games is mostly going to involve basic arithmetic, algorithms for enemy AI and dimensional worlds, rotation, and maybe some Algebra as well depending on how you want to design. But I ask because I'm not really gifted with math at all. I get frustrated and worn out just by doing Pre-Algebra, so Algebra 2 and Calculus would likely be futile for me. I guess I'm not so "right-brained" when it comes down to pure numbers and math formulas, but the bad part is that I'm no art-expert either. What do you people here suppose I should do? Go along avoiding as much of the extremely difficult maths I can't fathom, or try to ease into more complex math as I excel at programming?

  • Are there any resources for motion-planning puzzle design?

    - by Salano Software
    Some background: I'm poking at a set of puzzles along the lines of Rush Hour/Sokoban/etc; for want of a better description, call them 'motion planning' puzzles - the player has to figure out the correct sequence of moves to achieve a particular configuration. (It's the sort of puzzle that's generically PSPACE-complete if that actually helps anyone's mental image). While I have a few straightforward 'building blocks' that I can use for puzzle crafting and I have a few basic examples put together, I'm trying to figure out how to avoid too much sameness over a large swath of these kinds of puzzles, and I'm also trying to figure out how to make puzzles that have more of a feel of logical solution than trial-and-error. Does anyone know of good resources out there for designing instances of this sort of puzzle once the core puzzle rules are in place? Most of what I've found on puzzle design only covers creating the puzzle rules, not building interesting puzzles out of a set of rules.

  • C++ unmanaged inside winform

    First: I am using C# and C++ on windows 7. I have created a basic rendering engine in c++ with directx 10. It works good as a stand alone application. But, when I sending the Form.Handle of a WinForm I want to render inside to the engine it crashes during D3D10CreateDeviceAndSwapChain with the following error: HRESULT: 0x887a0001 (2289696769) Name: DXGI_ERROR_INVALID_CALL I get the handle from the winform during loading of the form. unsafe { void *ptr=m_view.Handle.ToPointer(); uint v = (uint)ptr; lhandle = v.ToString(); };

  • Understanding how to go from a scene to what's actually rendered to screen in OpenGL?

    - by Pris
    I want something that explains step by step how, after setting up a simple scene I can go from that 'world' space, to what's finally rendered on my screen (ie, actually implement something). I need the resource to clearly show how to derive and set up both orthographic and perspective projection matrices... basically I want to thoroughly understand what's going on behind the scenes and not plug in random things without knowing what they do. I've found lots of half explanations, presentation slides, walls of text, etc that aren't really doing much for me. I have a basic understanding of linear algebra/matrix transforms, and a rough idea of what's going on when you go from model space - screen, but not enough to actually implement it in code.

  • How do i add a start menu page to my java game?

    - by user2149407
    I have a rather cool space invaders game that my friend and I have been working on for a while, and we have decided it needs an opening page, with "Start" options, "Quit" options and so forth. I have looked at several methods online, but cant seem to get any of them to work! Does anybody have any ideas? P.S Using JFrame to draw the main frame Im just looking to do this within Java, so just a panel that appears at a state change (GAME, MENU). Id like it to contain a few buttons to start the game, and quit. Later, I will add achievements, but im after something really basic for now. But thanks for the suggestions!

  • Good source for interview-style coding problems for entry/intermediate developers?

    - by soster
    I have taught myself to code over the past few years and do not have a computer science degree. As a result, I lack experience from many things, such as the basic homework/test questions many CS graduates take for granted. I recently had a tech screen interview where I fumbled and struggled to finish a (relatively) common question, I believe due to this inexperience. My question to all of you is this: do you know a good source for a bunch of these problems that includes answers, for an entry/intermediate developer who is trying to gain coding problem solving experience? The ones I've been able to find on the internet are for coding teams, so they're a bit too complicated for me. Thanks so much in advance.

  • Someone who needs inspiration [on hold]

    - by Anestis
    My apologies if it is not a code problem. However, it is a problem that concerns programming. As a recently graduated Computer Systems Engineering I have gained some basic knowledge with programming using JAVA. I have realised 2 things, the first one is that I realy liked programming and the second is that I am not good at all. More specifically, I struggle on problem solving and when i face complex tasks I feel lost. Every day , I spend some quality time doing simple exercises in order to be more familiar with JAVA. My target is to become a good programmer and find a job on a software company. I am afraid maybe " I dont have it" thats why I am asking you , what should I do? Should i give up? Thanks in advance, Anestis

  • How to install libdvdcss?

    - by skwd
    I'm relatively new to Ubuntu and I'm trying to figure out how to play DVDs. I've read through a lot of forums, and got to the one asking how to read encrypted DVDs. I was able to do the first step and installed libdvdread4, but when I got to the second step of installing libdvdcss, I got what amounted to error messages. This is the command I ran: sudo /usr/share/doc/libdvdread4/install-css.sh Is there something important that I should know? As in, probably something basic that I don't know because I'm new...?

  • Why does Ubuntu Freezes on ASUS K42DY laptop with RADEON HD6470M Graphics Card?

    - by ix3
    Hi,I have an ASUS K42DY laptop with AMD Phenom II x2, 8 GB Ram , 500 GB Hard Drive and has a didicated ATI RADEON HD 6470M Graphics Card and I'm running Ubuntu 12.04 LTS 64bit on it. I have installed GNOME 3 and also followed this Make Ubuntu look like Mac OS X. I have also installed apps from the software center, getdeb & playdeb all of which worked fine. However, I noticed that Ubuntu freezes after inactivity let's say 1-3hrs. I have already set power setting to never standby or hibernate. This is completely annoying because all I can do is log-out via ctrl+alt+del or manually shut down and reboot my laptop. What should I do? By the way, this happens on all shells Unity, Gnome (even with the basic) and Cairo Dock.I set Swap Space at 8GB during installation. Any help will be appreciated. Thanks!

  • How to make a scrolling background?

    - by Liamh101
    I'm making a Shooter game like "1943" and "Jamestown". I was wondering how I would make the background scroll up to simulate moving forward. I would also like it to scroll slightly to the left and right when the player reaches the sides of the screen. Finally, how would I make this efficient? I was thinking about using a animated GIF or to make a looping BitMap. Please could someone help me out. (I am Using Visual Basic 2010) Thanks!

  • SharePoint 2010 slow page response time suddenly !

    - by H(at)Ni
    Hello, One of my customers faced a problem that suddenly their SharePoint portal was loading extremely slower than usual. After some basic troubleshooting I did not find anything suspicious in the ULS logs, IIS logs or even Event logs. After that, I came to the part that I like most which is capturing a memory dump for the IIS process and analyzing the threads running. I searched for any common mistakes like looping a large list, calling a remote web service but couldn't find any. After a deep analysis of the memory dump (Which was done by an Escalation Engineer for SharePoint), it seems that the farm root certificate was missing and therefore was trying to validate it from the internet every time the user requests to load the page and this was the resolution http://support.microsoft.com/kb/2625048 Cheers,

  • Start Programming embedded devices

    I am good at C programming and also I am good at embedded devices. I have setup an embedded circuit myself using the basic arduino and by interfacing some devices with it. But the main problem is that I do not know where and how to start programming this device with the known C programming skills. The device has an on chip boot loader. By "start programming", I mean how to bring the embedded device into my programming and stuff. I know program starts from a main() and an infinite loop makes the application run. But the real question is, how to start this all and integrate the hardware with the software which I write. Kindly help with this. Thanks for the help in advance.

  • Which optional features would you recommend for a raytracer? [closed]

    - by locks
    I'm developing a basic triangle mesh raytracer on a short deadline. This means I can't implement every feature I come across, so I'm looking for some feedback about which features you think are most important, taking into consideration the performance of the feature and how much punch it packs. I'm especially looking for optimization techniques that allow for a faster rendering and simple techniques that make a big impact on the final scene quality. Is there any chance of making it fast enough to run in realtime? Here are some example of features I've read about: Anti-aliasing Bounding box Sky box
