  • Do most programmers cut & paste code?

    - by John MacIntyre
    I learned very early on that cutting & pasting somebody else's code takes longer in the long run that writing it yourself. In my opinion unless you really understand it, cut & paste code will probably have issues which will be a nightmare to resolve. Don't get me wrong, I mean finding other peoples code and learning from it is essential, but we don't just paste it into our app. We rewrite the concepts into our app. But I'm constantly hearing about people who cut & paste, and they talk about it like it's common practice. I also see comments by others which indicate it's common practice. So, do most programmers cut & paste code?

  • What is the diffference between "data hiding" and "encapsulation"?

    - by john smith optional
    I'm reading "Java concurrency in practice" and there is said: "Fortunately, the same object-oriented techniques that help you write well-organized, maintainable classes - such as encapsulation and data hiding -can also help you crate thread-safe classes." The problem #1 - I never heard about data hiding and don't know what it is. The problem #2 - I always thought that encapsulation is using private vs public, and is actually the data hiding. Can you please explain what data hiding is and how it differs from encapsulation?

  • Where is a good place to start to learn about custom caching in .Net

    - by John
    I'm looking to make some performance enhancements to our site, but I'm not sure exactly where to begin. We have some custom object caching, but I think that we can do better. Our Business We aggregate news stories on a news type of web site. We get approximately 500-1000 new stories per week. We have index pages that show various lists of the items and details pages that show the individual stories. Our Current Use case: Getting an Individual Story User makes a request The Data Access Layer(DAL) checks to see if the item is in cache and if item is fresh (15 minutes). If the item is not in cache or is not fresh, retrieve the item from SQL Server, save to cache and return to user. Problems with this approach The pull nature of caching means that users have to pay the waiting cost every time that the cache is refreshed. Once a story is published, it changes infrequently and I think that we should replace the pull model with something better. My initial thoughts My initial thought is that stories should ALL be stored locally in some type of dictionary. (Cache or is there another, better way?). If the story is not found, then make a trip to the database, update the local dictionary and send the item back. Since there may be occasional updates to stories, this should be an entirely process from the user. I watched a video by Brent Ozar, How StackOverflow Scales SQL Server, in which Brent states "the fastest database query is the one that you don't make". Where do I start? At this point, I don't know exactly what the solution is. Is it caching? Is there a better way of using local storage? Do I use a Dictionary, OrderedDictionary, List ? It seems daunting and I'm just looking for some good starting points to learn more about how to do this type of optimization.

  • Default file permissions for php user www-data

    - by John Isaacks
    I have a php installed on my ubuntu machine. The web root is /var/www I set the permissions for this folder like so: sudo chown -R ftpuser:www-data /var/www ftpuser is the user I set up so I can ftp to /var/www from another machine on the network. www-data is the user php uses. I double checked using whoami from php. Whenever I ftp upload a new file to the machine the group has no permissions to the file. So when I try to access it in my browser via machine-name/new-file.php I am told permission denied and I have to go and chmod the new file. I am wondering if there is a way I can default the www-data user/group to have access permissions to new files so I don't have to keep chmod every new file?

  • Remote Display Config.sh Using SSH

    - by john.graves(at)oracle.com
    How often I see people look to VNC, NXMachine, RDP, etc to get a windowing environment on a remote system.  These products are great and I use them too, but there is a fancy feature in SSH to help. ssh –X remoteserver This is a great feature for hooking into headless VirtualBox machines and remote displaying an install wizard. The remote server must have some lines put in the /etc/ssh/sshd_conf file: X11Forwarding yes X11DisplayOffset 10 The second line is optional, but the first is required.  Restart sshd (sudo /etc/init.d/ssh restart). Now I can ssh –X remote server Then run /opt/app/wls10.3.4/wlserver_10.3/common/bin/config.sh to build a new domain. Note: For some reason, the jdk that comes with WebLogic often fails to work on the remote display.  In that case, I modify the config.sh to just use /usr/bin/java (from openjdk-6-jre package).

  • How to do geometric projection shadows?

    - by John Murdoch
    I have decided that since my game world is mostly flat I don't need better shadows than geometric projections - at least for now. The only problem is I don't even know how to do those properly - that is to produce a 4x4 matrix which would render shadows for my objects (that is, I guess, project them on a horizontal XZ plane). I would like a light source at infinity (e.g., the sun at some point in the sky) and thus parallel projection. My current code does something that looks almost right for small flying objects, but actually is a very rude approximation, as it doesn't project the objects onto the ground, but simply moves them there (I think). Also it always wrongly assumes the sun is always on the zenith (projecting straight down). Gdx.gl20.glEnable(GL10.GL_BLEND); Gdx.gl20.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); //shells shellTexture.bind(); shader.begin(); for (ShellState state : shellStates.values()) { transform.set(camera.combined); transform.mul(state.transform); shader.setUniformMatrix("u_worldView", transform); shader.setUniformi("u_texture", 0); shellMesh.render(shader, GL10.GL_TRIANGLES); } shader.end(); // shadows shader.begin(); for (ShellState state : shellStates.values()) { transform.set(camera.combined); m4.set(state.transform); state.transform.getTranslation(v3); m4.translate(0, -v3.y + 0.5f, 0); // TODO HACK: + 0.5f is a hack to ensure the shadow appears above the ground; this is overall a hack as we are just moving the shell to the surface instead of projecting it on the surface! transform.mul(m4); shader.setUniformMatrix("u_worldView", transform); shader.setUniformi("u_texture", 0); // TODO: make shadow black somehow shellMesh.render(shader, GL10.GL_TRIANGLES); } shader.end(); Gdx.gl.glDisable(GL10.GL_BLEND); So my questions are: a) What is the proper way to produce a Matrix4 to pass to openGL which would render the shadows for my objects? b) I am supposed to use another fragment shader for the shadows which would paint them in semi-transparent grey, correct? c) The limitation of this simplistic approach is that whenever there is some object on the ground (it is not flat) the shadows will not be drawn, correct? d) Do I need to add something very small to the y (up) coordinate to avoid z-fighting with ground textures? Or is the fact they will be semi-transparent enough to resolve that problem?

    I have one shopping site related to Home Goods and I need to create and submit the sitemap of my site in Google Webmaster Tool. I know there are several online tools to generate XML sitemap but some one told me that, Shopping site's sitemaps are different than other sites which means we have to submit sitemaps in two format. One is static page site map and another one is dynamic product page sitemap. Is it true? If so how create sitemaps in these two formats?

  • Java Not Recognized As Default Application

    - by John
    I just installed java according to this article, and 'java -version' displays java version "1.7.0_07" Java(TM) SE Runtime Environment (build 1.7.0_07-b10) Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode) 'update-alternatives --config java' returns this: There are 2 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ------------------------------------------------------------ 0 /usr/bin/gij-4.6 1046 auto mode 1 /usr/bin/gij-4.6 1046 manual mode * 2 /usr/local/java/jdk1.7.0_07/bin/java 1 manual mode Press enter to keep the current choice[*], or type selection number: with update-alternatives --config javac (or javaws) returning similarly. however java isn't listed in the default applications menu when I click on a .jar file and go to "open with application". I tried to install java this way, and on the update-alternatives part of the command returned me: /etc/alternatives/[java,javac,javaws] is dangling, it will be updated with best choice I just confirmed that I can use java, as 'java -jar file.jar' does work. Just figured that I'd mention it, don't know why I didn't before, but when I right click on a .jar file, java 7 run-time isn't even listed there, it seems that the file-manager isn't recognizing it as a program, but it is there, and it does work...

  • Preventing adult content in a forum

    - by John Doe
    I'm working on a forum that allows images attached to the posts and doesn't require registration. Thing is, I'd like to provide a work-safe navigation option in which the posts with porn images attached aren't shown. The ideas I've come up with are: Making the work-safe option the default and treating all posts with images attached as pornographic, and making them visible only if the user "unchecks" it. Making all posts with images attached not work-safe by default and changing their status to work-safe only after a moderator approved it. Only then they would be visible if the user has the "work-safe" option checked. Does anyone else have an idea? Also, how the big web services deal with this? (YouTube, CraigsList, even StackExchange). By the way, I don't think that "nudity detector" libraries are accurate and they give plenty of false positives and negatives. Thanks!

  • How to explain OOP concepts to a non technical person?

    - by John
    I often try to avoid telling people I'm a programmer because most of the time I end up explaining to them what that really means. When I tell them I'm programming in Java they often ask general questions about the language and how it differs from x and y. I'm also not good at explaining things because 1) I don't have that much experience in the field and 2) I really hate explaining things to non-technical people. They say that you truly understand things once you explain them to someone else, in this case how would you explain OOP terminology and concepts to a non technical person?

  • Mapping a 3D texture to a standard hollow-hull 3D model

    - by John
    I have 3D models which are typical hollow hulls. If such a model also had a 3D volumetric/voxel texture map then given a point P inside such a model, I'd like to be able to find its uvw coordinates within the 3D texture. Is this possible by simply setting 3D texcoords on my existing mesh or does it have to be broken up into polyhedra? Is there a way to map a 3D texture onto a mesh without doing this?

  • A way to return multiple return values from a method: put method inside class representing return value. Is it a good design?

    - by john smith optional
    I need to return 2 values from a method. My approach is as follows: create an inner class with 2 fields that will be used to keep those 2 values put the method inside that class instantiate the class and call the method. The only thing that will be changed in the method is that in the end it will assign those 2 values to the fields of the instance. Then I can address those values by referencing to the fields of that object. Is it a good design and why?

  • 403 error on index file

    - by John L.
    When I try to access index.py in my server root through http://domain/, I get a 403 Forbidden error, but when I can access it through http://domain/index.py. In my server logs it says "Options ExecCGI is off in this directory: /var/www/index.py". However, my httpd.conf entry for that directory is the same as the ones for other directories, and getting to index.py works fine. My permissions are set to 755 for index.py. I also tried making a php file and naming it index.php, and it works from both domain/ and domain/index.php.

  • Squeezing all the SEO out of a URL as possible.

    - by John Isaacks
    I am working on an ecommerce site, I told our SEO consultant that I plan to make the URL scheme: /products/<id>/<name>. This is similar to Stackoverflow's URLs which are /questions/<id>/<title>. He asked me if I could change the URL scheme to /p/<id>/<name> instead. I know why he wants this change, the word "products" isn't needed to find the correct product, and it doesn't offer any SEO, so shortening it to just p would make the relevant keywords in the <name> weigh more. His main priority is maximizing SEO, but the part that I don't think he is considering is how this effects the semantics of the site. Also having the word "products" looks like it has meaning and a reason for being there, just having a p looks chaotic and ugly to me. I also don't think it makes that much of a difference does it? Stackoverflow doesn't use /q/<id>/<title> and they do just fine, I do realize that theres many factors at play here though, not just the URL. So I want some outside opinions on which is the better way and why?
